Diaphragm Filter Press AdvantagesThe filter chamber of the diaphragm filter press is formed by staggered splicing of chamber plates and diaphragm plates, a solid filter plate and a diaphragm filter plate.The diaphragm plate of the diaphragm filter press has a diaphragm cavity on both sides. When the material is filtered, inject a certain pressure of gas (liquid) into the diaphragm cavity to make the diaphragm bulge and spin the filter cake in reverse to achieve the purpose of reducing the moisture content of the filter cake. When the press medium (such as compressed air) is passed through the back side of the diaphragm, these movable diaphragms will bulge toward the filter chamber, that is to say, the filter cake will be squeezed under high pressure again after the filtering process is over. The Nanxing chamber filter press is equipped with a membrane filter plate filtration process, and the moisture content of the filter cake can be 10-40% lower than that of ordinary filter plates. Can save a lot of follow-up costs. The filter part is composed of filter plates neatly arranged on the main beam and a filter medium sandwiched between the filter plates. Reinforced polypropylene filter plate is mainly made of high-quality polypropylene and pressed by our company’s unique formula. It has good mechanical properties, stable chemical properties, pressure resistance, heat resistance, corrosion resistance, light weight, flat and smooth surface, good sealing, and easy Features such as washing. At the beginning of filtration, the filter slurry is driven by the feed pump and enters each filter chamber through the feed port of the thrust plate. The filter slurry is separated from the solid and liquid by the pressure generated by the feed pump, due to the role of the filter medium (filter cloth) , Make the solid stay in the filter chamber to form a filter cake, and the filtrate is discharged from the water nozzle or the liquid outlet valve. If the filter cake needs to be washed, the washing water can be passed through the washing port on the thrust plate to wash the filter cake; if a filter cake with lower moisture content is required, compressed air can be passed through the washing port to pass through the filter cake layer and blow out Part of the water in the filter cake can be squeezed through the diaphragm to make the washing water less and the effect is better.

How to process mud sewage1. Concentration of sludge. The purpose of sludge thickening is to dehydrate sludge and reduce sludge volume, creating conditions for subsequent processing. Concentration and dehydration methods include gravity sedimentation concentration, floating concentration and other concentration methods.2. Sludge digestion. In order to reduce sludge amount, prevent environmental pollution and increase its utilization value, digestion treatment is generally required. Sludge digestion is the use of microbial metabolism to decompose the organic matter in the sludge into stable substances, remove odors, kill parasite eggs, and reduce the volume of sludge. The biogas produced in the digestion process is recycled.　3. Sludge dewatering and sludge drying. After the sludge is concentrated and digested, its water content is still about 96%, and the volume is large, which is not convenient for transportation and use. It needs further dehydration and drying treatment. The main methods are natural evaporation and mechanical dehydration.4. Sludge incineration. After the sludge is dried. The water content is still 10%-15%, and the volume is still large. The water and organic impurities in the sludge can be completely removed by incineration, and kill pathogenic microorganisms. Some sludge contains toxic substances and is not suitable for agricultural fertilizers, or it is difficult to use sludge for other reasons, in order to prevent pollution, Incineration method is also used. The device for burning sludge is an incinerator.　5. Final treatment of sludge. When the sludge contains toxic substances such as heavy metal ions, it must be finished, buried deep or thrown into the ocean.　In fact, in the above steps, if there is a mud-water separation equipment (horizontal plate filter press & Slurry Sewage Pump from our Nanxing company, it will save time.

Precautions for Filter Press Safe Operation10. Wash the filter press filter cloth as required to increase the water permeability of the filter cloth and improve the efficiency of filter press. 11. Before stopping, stop feeding and unload all the materials in the filter press before stopping. It is strictly forbidden to stop with materials. 12. After the board frame is loosened, after the slag is finished under one board, use a plastic spatula to clean the remaining waste, and then clean the other board. It is strictly forbidden not to clean the residue. 13. After unloading the board slag, when cleaning the board frame and filter cloth, ensure that the holes are unblocked, and do not allow the residue to stick to the sealing surface or the feeding channel. 14. When installing the board, when the board frame moves on the main beam, it must not be collided or beaten. The force should be evenly applied to prevent damage to the handle and damage to the sealing surface. 15. The damaged filter cloth should be replaced in time. When installing the filter cloth, it must be flat and not allowed to be folded to prevent damage and material leakage when the plate frame is compressed. 16. When storing the disassembled board and frame, it should be laid flat to prevent warping and deformation. 17. The sealing surface of the recessed filter plate must be clean and free of wrinkles. The filter plate should be vertical and tidy with the main beam, and must not be leaning forward and backward, otherwise the pressing action must not be started. 18. It is strictly forbidden to extend the head and limbs into the filter plate during the process of unloading the slag. 19. Leaking muddy water and damaged filter cloths should be replaced in time, washed, dried, stacked neatly, and treated in a unified manner. 20. Keep the filter cloth free from entrainment and wrinkles. Keep the surface of the pp chamber filter plate flat and smooth. The handle of the filter plate should be handled gently. When pressing, ensure that the filter plate discharges neatly and does not deviate from the compression centerline.
