At present, many friends who don't know about the filter press equipment think that the plate and frame filter press and the diaphragm filter press are the same type of machine because they are all frame type. In fact, there is a difference between the two. Here is a detailed introduction to the distinction between plate and frame filter press and membrane filter press: The basic principle and the same structure of plate and frame filter press and diaphragm filter press are different in that the filter plate used by diaphragm filter press is double with diaphragm cavity. The membrane filter plate and the filter plate with the same shape are arranged at intervals to form a filter chamber with a certain volume. When the material filtration is completed, gas (liquid) with a certain pressure is injected into the membrane chamber) make the diaphragm bulge and rotate the filter cake in reverse direction to achieve the purpose of reducing the moisture content of the filter cake. Compared with the filter plate of ordinary box type or frame type filter press, the diaphragm filter plate has two filters which can move back and forth and one membrane. When squeezing medium (such as compressed air) is introduced to the back of the membrane, these movable membrane will be bulged out in the direction of the filtering Chamber, that is to say, after the filtering process is over, press the filter cake again under high pressure. The benefits brought by the diaphragm filter plate to you are: equipped with the filtration technology of the diaphragm filter plate, the moisture content of the filter cake can be 10-40% lower than that of the ordinary filter plate. It can save you a lot of follow-up costs (see benefit analysis for details ). At the same time, when washing the filter cake, the washing water can be less and the effect can be better by squeezing the membrane. The above is the distinguishing point between plate and frame filter press and membrane filter press.
Precautions for the use of filter press in winter, plate and frame filter press is a kind of filter press, the purpose of this filter press is to accumulate the moisture contained in the slurry, but not all the weather is suitable for this kind of filter press to work. If it is under extremely low temperature, if this kind of filter press wants to work better, it still needs to be observed with certain precautions. 1. Water in low temperature is easy to freeze Because when the plate and frame filter press is working, it is to accumulate the water inside the object to the greatest extent of love, but under extremely low temperature, the water is very easy to freeze, in this way, it is easy to cause damage to the machine, and the following work cannot be carried out. Therefore, in the low quarterly temperature, if you want the plate and frame filter press to work normally, you need to pay attention to keep the plate and frame filter press warm in time to prevent the machine from freezing. 2. It is easy to cause filter plate deviation and filter cloth damage Under low temperature, some machines are easy to deform, and the plate and frame filter press is no exception. In this case, if you still insist on working, it is easy to cause the plate and frame filter press to malfunction and the filter plate to deviate, if the machine is not working, it will be a very serious accident if an accident hurts people. After removing the filter plate, the slurry is easy to freeze and stick to the filter cloth at low temperature. If the filter cloth is not processed timely at this time, it is easy to cause the damage of the filter cloth, and the filter press of the plate and frame can not continue to be used. 3. If there is no water object, you need to use it carefully When the plate and frame filter press is working at a low temperature, it is easy to freeze after removing water, and the machine may change...
At present, with people's emphasis on environmental protection, the filter press market in our country is still thriving, and the filter press manufacturers are also constantly improving their technical level steadily in the development of the industry, but the filter press manufacturers can not satisfy this, they should strengthen the scientific research in the technical field aiming at the high-end market, and further strengthen the strength of the industry. With the acceleration of industrialization in our country, filter press manufacturers have continuously improved the application technology in the industry. How difficult is the current technology situation faced by the filter press industry in our country, which means that there is much room for improvement in the future. The filter press was first introduced from abroad, but with the continuous improvement of the filter press equipment technology in our country and the improvement of the supply chain of related supporting equipment, our country has basically realized the independent research, development and manufacture of the filter press equipment at present. Moreover, in terms of performance, the gap with foreign similar equipment is also narrowing. However, in terms of some high-end industrial demand, filter press manufacturers still have more space to improve, and the high-end industry will certainly develop in the future, and the demand will further increase. For the production demand of general filter press manufacturers, the filter press independently developed and produced in our country is enough to meet the production demand of most enterprises, and there is still a certain gap between the management and technology of filter press manufacturers. Because the development speed of modern industry is very fast, for some high-end markets, many enterprises in our country can't meet these demands of high precision and high strength technically because they start relatively late, the filter press manufacturer aims at the performance, working intensity, service time and other aspects of the filter press equipment. Supply of supporting parts related to filter press manufacturer...
Sometimes, due to long working time, high ambient temperature, high pressure and other reasons, the filter press will have transitional work phenomenon. The filter mechanism of sand washing filter press consists of filter plate, filter frame, filter cloth and squeezing membrane. Both sides of the filter plate are covered by filter cloth. When squeezing membrane needs to be configured, a group of filter plates consist of membrane plate and side plate. The two sides of the base plate of the diaphragm plate are covered with rubber membrane, and the outer side of the membrane is covered with filter cloth, and the side plate is the ordinary filter plate. When there is transition work, we need to do some work to slow down the solution and make the filter press run more effectively. Therefore, how to judge the transition work of filter press is very necessary. Next, let's talk about some performance of the filter press transition. The poor quality of filter cake after filtration is the main manifestation of the work transition of filter press equipment. Once the filter chamber is not perfect, the solid-liquid separation will be unwillingly realized, and the final filter cake may not achieve the expected effect in moisture content and formation, or the moisture content of the filter cake may become higher, or the filter cake cannot fill the gap of the filter chamber, etc. The transition work of filter press is first reflected in the power system. The power system of the filter press not only provides power for the operation of each part of the equipment, but also provides strong pressure for the filter plate, making the filter plate become a closed filtering environment. When the filter press equipment works for a long time, the hydraulic oil of the hydraulic system may be overheated, making the hydraulic oil no longer able to bear relatively strong pressure, and its volume will change with the change of pressure. This directly results in that the hydraulic system cannot generate enough power. In the working process, when the power system of the equipment can not generate pressure normally, the pressure acting on the filter plate will naturally decrease, acting on the filter plate...
The filter press produced by our company has the characteristics of high degree of automation, large daily processing capacity, high filtering precision, low labor intensity, small floor area and so on. It is widely used in the solid-liquid separation of all kinds of sewage and sludge, and is committed to providing advanced and efficient integrated filtration system for global customers. When it comes to the filter equipment, I believe we think of the filter press at the first time, and the filter press can basically be divided into three types: box filter press, plate and frame filter press and membrane filter press. The most widely used one is the diaphragm filter press. Today, let's explain what effect the diaphragm filter press has. Why can't the environmental management of various industries be separated from the diaphragm filter press? The diaphragm filter press and the Chamber filter press both use the same feed shunt channel, and enter the Channel in the center of the filter plate. In this way, the filter liquid imported from the feed inlet moves evenly from the center of the filter plate to all directions, make the filter cloth and filtrate fully touch to achieve the effect of filtration and separation. It also makes the forming of blocked filter cake more uniform than before, creating conditions for subsequent operations. In addition, the rubber diaphragm filter press is an advanced technology introduced from abroad. It is manufactured by using the implantation method of vertical fiber and static electricity, taking its essence and discarding its dregs. Finally, it is a kind of water equipment processing machine developed, it can work continuously for a long time and a large amount of sludge can be operated continuously. This is also due to its own structure. The filter press uses three kinds of matching equipments with different lengths, and at the same time, it also uses super high quality strainers for filtering operation, thus, the function and quality of the filter press and the function and quality of finishing the operation are ensured. Now you know the diaphragm filter press...
First of all, many people think that the filter press provides a lot of pressure, which can make the liquid press over the hydraulic station through the filter cloth. But the fact is not true. The pressure provided by the filter press only increases the pressure difference between the two sides of the filter cloth, making the filtrate have stronger kinetic energy, which accelerates the liquid channel. The speed of the filter cloth is actually the same as the pressure of the filter. Just like the increase of the water level of the power station, it forms a certain decline and the kinetic energy brought by falling. Secondly, the number of screens of the filter cloth only affects the filtering effect. This is not the case. The filter cloth affects the size of intercepting solid, and the number of curtains of the filter cloth also affects the filtering speed of the filter press (the number of curtains is density ). The larger the number of filter cloth curtain is affected by other factors, and the slower the filtering speed is under the same conditions. Moreover, the filter cloth also needs to be cleaned frequently. Beibang environmental protection suggests that customers clean it once in about half a month. I believe that many customers have no habit of cleaning the filter cloth, and they will replace it until the filter cloth can not continue to be used, but this will have a great impact on the filtering effect of the filter press and the service life of the filter press. The last is the misunderstanding about the diaphragm filter plate of the diaphragm filter press. Many people think that it is impossible to design the drainage channel. In fact, the part of the diaphragm filter plate needs to be expanded in the middle and usually does not move. We just need to design the drainage channel to the edge. Like box filter press, each filter plate can be emptied to make the equipment passageway smoother. Do you understand the above misunderstanding?
