detailed information

Current situation of slaughter sludge

The slaughterhouse is a typical heavily polluting industry, and its production process generates a large amount of sludge, mainly composed of animal excrement, food residues, cleaning wastewater, etc. These sludge contain high moisture content and organic matter content. If not treated properly, they will have a serious impact on the environment and human health. Sludge treatment in slaughterhouses is also an essential task for modern slaughterhouses.

Introduction to Plate and Frame Filter Press

It has the advantages of high filtration driving force, high solid content of filter cake, clear filtrate, high solid recovery rate, and low consumption of conditioning drugs, and is widely used in sludge dewatering projects in various industries.

Structure of Plate and Frame Filter Press

The plate and frame filter press consists of a set of filter chambers composed of alternately arranged filter plates and filter frames. The surface of the filter plate has grooves, and its protruding parts are used to support the filter cloth. There are through holes on the corners of the filter frame and filter plate, which form a complete channel after assembly, allowing suspension, washing water, and filtrate to be introduced. Both sides of the board and frame are supported by handles on the crossbeam, and are compressed by a clamping device. The filter cloth between the board and the frame serves as a sealing gasket. The suspended fluid is pumped into the filter chamber by the feed pump, forming filter residue on the filter cloth until the filter chamber is filled. The filtrate passes through the filter cloth and flows along the groove of the filter plate to the corner channel of the plate frame, and is discharged in a concentrated manner. After filtration, the filter residue can be washed with washing water. After washing, sometimes compressed air is also introduced to remove the remaining washing solution. Then open the filter press to remove the filter residue, clean the filter cloth, re press the plate and frame, and start the next work cycle.

Function of Plate and Frame Filter Press

Plate and frame filter press is used for solid-liquid separation. Compared with other solid-liquid separation technology equipment management, the mud cake filtered by the filter press has a high solid content and excellent separation control effect. With the changes in product model requirements, especially in food filtration requirements, it is not only required that food filtration be simple and novel, but also pay more attention to the reliability of the material of the plate and frame products. The plate and frame filter press uses some high-tech plate and frame materials, which are safe, reliable, free of heavy metals, and have relatively stable performance. Different materials have made a significant contribution in food filter press. With the application of technology, today's plate and frame filter presses are not only used in other fields, but also widely used in the food industry. The plate and frame filter press is suitable for suspensions with high compressibility or near incompressibility of filter residue. The solid particle concentration of suitable suspension is generally below 10%, and the operating pressure is generally 0.3-0.6MPa, with some reaching 3MPa or higher. The filtering area can increase or decrease with the number of frames used. The frame is usually square, with an inner edge length of 320-2000mm, a frame thickness of 16-80mm, and a filtering area of 1-1200 square meters. The board and frame are tightened using manual screws, electric screws, and hydraulic methods. The plates and frames are made of materials such as wood, cast iron, cast steel, stainless steel, polypropylene, and rubber. The Petrochemical Plant 5 uses polypropylene filter plates.

Advantages of Plate and Frame Filter Press

Advantages: Simple structure, easy operation, stable operation, and convenient maintenance. The selection range of filtration area is flexible and occupies less space. Strong adaptability to materials, suitable for various small and medium-sized sludge dewatering treatment scenarios.

The outstanding advantage of the flexible transmission system of the plate and frame filter press is that when the filter plate tilts, it does not affect the normal operation of the discharge cake and the deformation of other structural components. It is a highly reliable transmission system. Considering the basic requirements for daily operation and replacement of filter cloth, the innovative design of the pressure pipe filter cloth rack is very convenient. When replacing the filter plate normally, there is no need to disassemble the hinged steel plate, and the vibration beam is not shielded. After moving the flexible steel wire rope, the filter plate can be easily lifted, providing good working conditions for maintenance.

Plate and frame filter press equipment is favored by customers in sludge dewatering and other treatments, mainly including filter presses and centrifuges. Compared with these two types of equipment, the procurement cost of sludge centrifuge is higher, and the maintenance cost in the later stage is also higher. Therefore, more and more users are choosing plate and frame filter press equipment. The plate and frame filter press is gradually gaining market recognition and attracting the attention of many buyers.
