Filter plates of different materials are needed in different production environments, so what are the common materials of filter plates? Let's take a look together. 1. Nowadays, the most common thing is to say PP polypropylene filter plate, that is to say, the polymer material polypropylene. This kind of material has good resistance to various kinds of pH, including strong alkali hydrochloric acid, which often has excellent resistance. However, the range of operating temperature is relatively small. Most of them are raw materials with tolerance of 70 ° in the short term. The filter plate of high-pressure filter machine is an organic chemical material with alkali resistance and good resistance. All normal high temperature resistance can reach around 150 °, but the corrosion resistance deviation. 2. The filter plate of estrangement filter press has good ductility, and the water content of the filter cake has already been guaranteed to be below 30%. 3. The filter plate of vulcanized rubber filter press has high corrosion resistance, heat resistance and high tightness. 4. Aluminum filter press filter plate, in all metal material filter press, is light, but relatively speaking, it has weak tolerance to acid and alkali. 5. Filter plate of pig iron filter press, net weight, weak alkaline resistance and extremely high heat resistance. In fact, it is necessary to apply organic chemical materials to make surface protrusion, therefore, it is also an inevitable limitation. 6. The filter plate of stainless steel plate filter press has good corrosion resistance, but the price is much higher than that of all filter presses. After all, the price of the material itself is expensive, and it takes a lot of time to process. The actual work of the filter press is to create a robust driving force according to the hydraulic press management system. The actual effect is on the filter plate of the filter press, only in that way can the separated filter press filter plate form a necessary part of the machine equipment when working...
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...
