Working principle of cast iron plate and frame filter press
2023 / 08 / 12
Working principle of cast iron plate and frame filter press The plate and frame filter press consists of a set of filter chambers arranged alternately through filter plates and filter frames. There are grooves on the surface of the filter plate, and the 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, and can pass into the suspension, washing water and lead out the filtrate. There are handles on both sides of the plate and frame to support the beam, and the plate and frame are pressed by the pressing device. The filter cloth between the plate and the frame acts as a sealing gasket. The suspension is hydraulically pumped into the filter chamber by the feed pump, and filter residue is formed on the filter cloth until the filter chamber is full. The filtrate passes through the filter cloth and flows along the groove of the filter plate to the channel at the corner of the plate frame, where it is discharged concentratedly. After the filtration is completed, the filter residue can be washed with clean water. After washing, sometimes compressed air is introduced to remove the remaining washing liquid. Then open the filter press to remove the filter residue, clean the filter cloth, re-press the plate and frame, and start the next working cycle. The plate and frame filter press is suitable for suspensions with high compressibility or nearly incompressible suspensions. The plate and frame are usually square, and the plate and frame are compressed by manual screw, electric screw and hydraulic pressure. Plates and frames are manufactured from materials such as wood, cast iron, cast steel, stainless steel, polypropylene and rubber. Plate and frame filter presses are used for the separation of solids and liquids

2023 / 07 / 18
Causes, hazards and solutions of high slurry inlet pressure of chamber filter press 1. Reasons and hazards of high pulp inlet pressure of box filter press 1. 1.Reasons for high slurry feeding pressure (1) Excessive slurry feed flow: If the feed flow exceeds the range that the box filter press equipment can handle, the box filter press will be subject to excessive pressure, resulting in an increase in the slurry feed pressure. (2) Blockage of filter medium: When the filter medium (such as filter cloth or filter plate) is blocked by solid particles, it will hinder the passage of liquid and cause the pressure of slurry to increase. (3) Damage to the filter medium: Damage to the filter medium will increase the resistance of the fluid to pass through, thereby increasing the slurry feeding pressure. (4) Increase in liquid viscosity: The increase in liquid viscosity will lead to an increase in the resistance of the liquid through the filter medium, thereby increasing the slurry feeding pressure. 2. The danger of high slurry feeding pressure (1) Increased force on the equipment: Excessively high slurry inlet pressure will cause the filter press to be subjected to additional force, which may cause deformation, rupture or other structural damage of the equipment. (2) Decreased filtration efficiency: Excessively high slurry inlet pressure will affect the solid-liquid separation process, resulting in a decrease in filtration efficiency and failing to achieve the expected separation effect.

Working principle of the pile sludge filter press
2023 / 06 / 01
Working principle of the pile sludge filter press After the pile type sludge filter press has been pressed, it is ready for feeding operation. Turn on the feed pump and slowly open the feed valve, the feed pressure gradually rises to normal pressure. After filtering for a period of time, the amount of liquid discharged from the liquid outlet hole of the plate and frame filter press gradually decreases. At this point, it indicates that the filter residue in the filter chamber is gradually filling. When no liquid comes out of the outlet hole or only a small amount of liquid, it proves that the sludge in the filter chamber has been completely filled and formed into a filter cake. The pile type sludge filter press consists of a group of filtration chambers with alternating filter plates and filter frames. The filter plates have a groove on their surface with a protruding part to support the filter cloth. The filter frames and filter plates have a through-hole in the corner and when assembled form a complete channel for passing the suspension, washing water and leading the filtrate.

What are the factors that affect the normal use of a slurry filter press?
2023 / 05 / 26
As the mud filter press is usually used in a poor environment that does not contain a certain concentration of acidic gases, or is full of kerosene, alkaline dust, etc., the damage and build-up of these corrosive chemicals on the electrical components of the filter press may lead to electrical problems and the formation of control buttons without care. When the mud filter press control button is invalid, first check whether the structure and contacts of the filter press control button itself are normal. Check method: press the corresponding button and investigate whether the corresponding node indicator at the PLC input can be lit. If there is no problem with the button, stop checking the relevant terminal wires if no response button is pressed. The slurry filter press operates by means of a hydraulic system that produces a powerful power effect on the filter plates. Only in this way can each separated filter plate form the local filter chamber necessary for the operation of the machine, i.e. a certain number of filter plates must operate under a strong pressure effect. When the pressure inadvertently exceeds the acceptance range of the filter plates, the plates will naturally split and be damaged. When unloading, the convex edges around the filter plate of the filter press tend to wear away. Once the edges are badly worn, the resulting filter chamber will not be sealed and the strongly pressurised liquid within the filter chamber will leak or spurt out through the worn area. The slurry filter press will increase the level of wear on the filter plate during the movement of the liquid, resulting in complete damage to the filter plate.
How fast diaphragm filter presses are used in the coal processing industry?
2023 / 05 / 04
How fast diaphragm filter presses are used in the coal processing industry? The fast diaphragm filter press is used in the coal processing industry to separate solids from liquids in the slurry produced during coal washing and processing. The Filter Press is designed to remove water from the slurry, leaving behind a Filter Press Cake of dry solids that can be easily transported and disposed of. The fast diaphragm Filter Press Machine is particularly well-suited to coal processing because it is highly efficient and can handle large volumes of slurry. The press uses a series of diaphragms to apply pressure to the slurry, forcing the water through a series of filter cloths and leaving behind a cake of dry solids. The diaphragms are designed to move quickly, allowing the press to process large volumes of slurry in a short amount of time. The fast diaphragm Filter Presses is also highly automated, with sensors and controls that monitor the process and adjust the pressure and flow of the slurry as needed. This makes it a reliable and efficient tool for coal processing plants, where large volumes of slurry must be processed quickly and efficiently.

2023 / 05 / 03
Shenzhen Hongfa filter press plant sand and gravel wastewater zero discharge treatment system The traditional mud treatment process is to use sedimentation pond treatment, pour the mud into the sedimentation pond for natural air-drying, this natural air-drying method through this sedimentation pond is easy to be affected by the weather, and the time to complete the air-drying treatment is also relatively long. Moreover, if the terrain does not allow, it will cause secondary pollution to the surrounding environment and cannot fully meet the standard of recycling or discharge. Due to the reduction of environmental protection and resources, the mining of river sand is becoming less and less, and the mechanism sand is gradually replacing river sand, but more sand farms often do not pay enough attention to the slurry sewage treatment after sand washing. Sand washing mud sewage is discharged without treatment or directly into the nearby rivers, causing water pollution, disturbing the water ecological balance around the rivers, aggravating the coastline collapse, and posing major hidden dangers. This also makes the river channel shallow and increases flooding during the rainy season. The zero discharge system of sand washing wastewater developed by Shenzhen Hongfa Filter Press Factory is a new type of sewage and slurry treatment system with the functions of environmental protection, recycling and reuse, etc. It is a systematic solution to the problems of sewage purification and dry discharge of solid waste in mechanism sand plant. It has large treatment capacity, low operation cost, intelligent unattended, and meets the demand of waste water recycling in sand and gravel industry.
