Method for processing injection phenomenon in a plate frame filter board
Frame Bill filter plate The processing method of the injection phenomenon 1, it may be that the feed pressure is over Highly causing the injection, many users do not install the pressure gauge on the feed line, resulting in out of control, causing spray. 2, the topping force of the filter plate is insufficient, and the force between the feed press is increased, and the filter plate is supported by the filter plate. 3, filter cakes such as filter cakes and other debris attached to the surface, and the filter plates always have a larger slit after the filter plate is pressed, so the sealing surface should be cleaned after the filter cake is removed. 4, the filter plate sheet has a through trench or the filter plate itself is damaged.
What is the advantages and disadvantages of a board frame filter? The plate frame filter is extruded through the plate frame, so that the water in the sludge is discharged through the filter cloth, and the purpose of dehydration is achieved. It is mainly composed of a concave-type filter plate, a frame, an automatic-pneumatic closed system plate suspension system, a filter plate vibration system, an air compression device, a filter, high pressure flushing device, and a body side photoelectric protection device. The advantage is that the price is cheap, the mud cake is high; the disadvantage is that the intermittent operation is large, the area is large, and the maintenance frequency is high. So now Most sewage treatment plants have no longer use this equipment. Let’s first take a filter room. I believe that as long as you see the horizontal filter machine, you know the extremely important part of the board frame filter machine. It is a separately separate filter plate, which holds the filter cloth in the middle, then pass through The equipment provides powerful pressure to make them a filter chamber. It is mainly to bear the separation of the filter. When it works, it is full of filtrate, and they can be very high, if there is a tiny place in the filter room, it is not enough to cause the overall inside the filter chamber. High, resulting in the flow of the filtration to flow in normal filtering path, thereby affecting the efficiency and quality of the equipment. In addition, the filtrate is also constantly penetrating from no secret, which not only reduces the quality of equipment, but also adds the use of devices, causing waste of equipment. It can be seen that the normal operation of the filter machine equipment must be filtered in the filter chamber.
