Feeding operation of plate and frame filter press in filtration process

It plays a prominent role in the industrial filtration process. If the feeding speed is too fast in the process of use, it may also lead to the failure of the plate and frame filter press. This is mainly because the fast feeding speed will easily cause the blockage of the plate and frame filter press. Therefore, reasonable control of feeding speed can make the plate and frame filter press work more smoothly.


In general, in the industry's filter production line, the plate and frame filter press in different stages of its feed speed is not the same, plate and frame filter press press at the beginning of the filter, the filter chamber pulp is not too much, the thickness of the filter cake is not large. Therefore, a fast packing speed should be adopted to ensure that the plate and frame filter press can be filled in time to ensure that there is enough pressure in the filter chamber. When the plate and frame filter press has been running for some time, the feeding speed should be slowed down so as to avoid too much feeding and causing clogging of the plate and frame filter press.


The outstanding advantage of the flexible transmission system of the plate and frame filter press is that it does not affect the normal operation of the cake unloading and does not cause the deformation of other structural parts. It is a highly reliable transmission system. Fully considering the basic requirement of frequent replacement of press cloth in daily operation, an innovative pressure tube press cloth rack is designed to make it convenient to replace press cloth. When the filter plate is normally replaced, there is no need to remove the hinged steel plate, nor does it have the cover of vibration beam. After moving the flexible wire rope, the filter plate can be easily lifted, creating a good working condition for maintenance.


The new plate and frame filter press can not be put into work directly. It needs to go through the necessary debugging before it is officially used, and it can only be put into operation after it is confirmed to be qualified for debugging. Debugging work before use of plate and frame filter press:


1. Clean and check the hydraulic station, electric control box and other parts of the plate and frame filter press. Clean these parts first. 2. First, ensure the correct installation and check whether the upper and lower limits of the electrical contact pressure meter of the plate and frame filter press meet the requirements.


3, check the power wiring, pay attention to the waterproof and moisture-proof, the layout should be safe and reasonable, avoid the equipment in the work of the power cord. Clean the frame, filter plate and piston rod. Check whether the filter plate is arranged neatly and correctly. Thirdly, check the press cloth to see if it is folded or flattened.


4. Check whether the configuration of pipes and valves, such as feeding, washing, blowing and discharging, is correct and reasonable.


The plate and frame filter press must do the above debugging work before putting into use, for the plate and frame filter press that has been out of use for a period of time, can also be adjusted before putting back into use, which is an important guarantee for the use efficiency and safety. Open all outlet valves of plate and frame filter press, close the valve of washing and blowing washable type, open the feeding valve about 1/4, start the feeding pump at this time, check the change of filtrate and feeding pressure, if the pressure is too high, open the valve on the return pipe to adjust. Due to the capillary effect of the filter cloth of the plate and frame filter press, the filtrate will look cloudy at the beginning of the filtration, which is a normal phenomenon.
