Nowadays, no matter what kind of equipment it is, it can exert excellent working efficiency under good operating condition, so does the plate and frame filter press, which adjusts all preparation work and parameters to the best state, it can naturally achieve better sludge treatment effect. But for sludge treatment enterprises without experience in using plate and frame filter press, what details should be paid attention to when adjusting to the best sludge treatment effect? From what aspects? As follows, beibang environmental protection technical engineer made a summary of the adjustment of plate and frame filter press: the contact part between the filter cloth and filter plate of plate and frame filter press should be guaranteed to be flat and no wrinkles can occur, prevent the filter cloth from being squeezed by the filter plate to form damage or mud leakage. To prevent the tail of the buckle from being too long or reaching into the place where the filter plate is pressed to damage the filter cloth, or form mud leakage, the short tail should be cut off. When the plate and frame filter press device is installed, it should be noted that there is no foreign matter or larger sludge particles between the filter cloth and the filter plate, and larger sludge particles or foreign matter may be in the plywood, which will easily cause damage to the filter plate or filter cloth. In addition to the details that need to be paid attention to above, beibang environmental technical engineer said that the following points should also be paid attention: 1. Check carefully at any time whether each joint is firm and whether the running contact of each component is good. If any abnormality is found, inform the repair personnel to repair it in time. The plate and frame filter press has strict requirements on the electric control system, and the insulation and reliability tests should be conducted regularly. If the movement accuracy is poor and insensitive caused by electrical components are found, it should be repaired or replaced timely. 2. Regularly inspect the parts such as pulling plate trolley, sprocket chain, bearing, piston rod and so on...
Filter press is divided into box filter press, plate and frame filter press, membrane filter press, automatic filter press, circular filter press and so on; I. Components The structure of filter press consists of three parts: 1. Rack rack is the basic component of filter press, both ends are thrust plate and compression head, and the girders on both sides connect the two together, the girder is used to support the filter plate, filter frame and compressing plate. In order to meet the needs of advanced hygiene, the rack needs to be wrapped with stainless steel. The package stainless steel technology of Hangzhou Gerent can be used as a reference, and its quality can meet the needs of European customers. A. Thrust Plate: it connects with the bearing to place one end of the filter press on the foundation. In the middle of the thrust plate of the box-type filter press is the feed hole, and there are four holes at four corners, the holes in the upper two corners are the inlet of washing liquid or squeezing gas, while the lower two corners are the outlet (undercurrent structure or the outlet of filtrate ). B. Compressing plate: it is used to compressing the filter frame of the filter plate, and the rollers on both sides are used to support the compressing plate to roll on the track of the girder. C. Girder: it is a load-bearing component. According to the anticorrosion requirements of the using environment, hard PVC, polypropylene, stainless steel coating or new anticorrosion coating can be chosen. 2. Compressing mechanism Manual pressing, mechanical pressing and hydraulic pressing. A. Manual pressing: push the pressing plate with spiral mechanical Jack to press the filter plate tightly. B. Mechanical compaction: The compaction mechanism consists of electric motor (equipped with advanced overload protector) reducer, gear holder, screw rod and fixed nut. When compressing, the motor rotates forward, driving the reducer and the gear pair, making the lead screw rotate in the fixed silk thread, pushing the compressing plate to compact the filter plate and the filter frame. When the tightening force becomes bigger and bigger...
Application materials: mining application equipment: plate and frame filter press Scheme Introduction: Mine waste water mainly comes from pit water discharged from mining production, rain waste water from waste stone yard and ore washing and tailings waste water discharged from ore dressing plant, according to the analysis of Bebon laboratory, there is a certain amount of special acidic waste water in the Experimental Mine waste water, including heavy metals such as mercury, cadmium, lead, chromium and other elements with significant toxicity such as non-metallic sulfur and arsenic, and there are some toxic elements such as zinc, copper, nickel, etc., and the tailing leachate will cause the pollution of groundwater and soil. The scheme we give is: flow into the three-layer sedimentation tank through the drainage ditch, the water through the three-layer sedimentation tank can be recycled after long precipitation. Use a mixer in the three-layer sedimentation tank, stir evenly, and use a slurry pump to drive the slurry from the three-layer sedimentation tank into the slurry tank. Use the medicament conditioning tank to add medicine (add the medicament into the mud tank through the medicament tank). After the mud tank is evenly stirred by the mixer, it is provided by the plunger Mud Pump (the plunger mud pump needs to be specially customized, using the spherical valve core) dripping into the filter press for dehydration treatment, the mud cake formed by the treatment is pulled away and buried, and the clean water flows into the clear water tank for recycling, finally achieving the purpose of turning the sewage into clean water.
Applied Materials: printing and dyeing wastewater applicable equipment: diaphragm filter press Scheme Introduction: The Laboratory of our company has conducted laboratory analysis on the waste water of the printing factory, and the difficulty is that the quality of the waste water mixed with high concentration waste liquid fluctuates greatly, the conductivity is high and the biological treatment is difficult, it is difficult to remove the index such as amine and AOX. The processing scale of this printing factory is 1000 T/D, and the diaphragm filter press is recommended. This machine adopts the whole structure of concentrated filter press, with compact structure, it occupies a small space and has a relatively large processing capacity, which is suitable for the rapid dewatering treatment of industrial sludge with a large amount of mud. It is a preferred model for sludge dewatering in printing and dyeing industry. Part of the emission standard is used back for production, and the rest reaches the discharge standard of water pollutants in textile dyeing and finishing industry.
Applied Materials: Machine sand applicable equipment: plate and frame filter press Scheme introduction: This project is in Shandong province. After understanding the demand, the Project Department designers of our company designed a combination of sand washing machine recycling integrated machine, sedimentation tank and plate and frame filter press according to the terrain, first, discharge the crushed machine sand into the sand washing machine and recycle all-in-one machine, then discharge all the waste water produced by the sand washing machine into the sedimentation tank, and use the medicament to make the mud precipitate quickly, after sedimentation, the supernatant can be directly discharged or recycled, and the precipitated thick mud can be pumped into the plate-frame filter press through a high-pressure pump, and the filter cake after the filter press has been very dry, it can reach the situation that the hand can't pinch the water completely, and then load the produced filter cake directly through the belt conveyor and transport it to the recycling place designated by the company.
Prebiotic production is not only a production mode with the main goal of minimizing the resources occupied by production and reducing the cost of enterprise management and operation, but also a kind of enterprise culture, the goal is to strive for perfection and perfection, and to pursue the ultimate goal of seven "zeros" endlessly.
