After the diaphragm filter press operates for a period of time, when the filter cake in the filter chamber is filled with filter cloth, the equipment will not be able to continue the solid-liquid separation operation. Therefore, when the filter cake fills the entire filter chamber, it is difficult to remove the filter cloth from the filter cloth. Therefore, at this time, the feeding system of the membrane filter press stops feeding, and the feeding hole is temporarily closed. At this time, the filter plate expansion system of the membrane filter press will start to run.
How does the filter plate expansion system of the diaphragm filter press work? The first is to start the hydraulic pump, and then press the continuous hydraulic oil into the filter plate. Then, a large amount of hydraulic oil will accumulate in the hollow space of the diaphragm filter press. When the hydraulic oil As it continues to increase, the filter plate will expand outward. This will cause the filter cake to be kneaded and the volume of the filter cake will decrease. At this point, the filter cake will be kneaded and the remaining liquid will be discharged. This will greatly reduce the filter Cake. Moisture content.
Do you know the equipment and debugging process of the diaphragm filter press?
1. The diaphragm filter press should be installed on a flat concrete foundation. The thrust plate feet at the feed end are fixed on the foundation through anchor bolts. There is no need to use anchor bolts at the end of the bracket, and there is no need to use 2 nuts to locate and determine The machine feet can be pulled slightly by removing the anchor bolts and leaving a proper gap between the nut washers and the feet. Before equipment, the equipment personnel should correct the straightness of the beam and the large plane of the thrust plate.
2. The foundation structure should be designed by the construction engineer according to the load of the equipment, and the anchor bolts should be filled with two reserved holes.
3. There should be enough space for operation and maintenance around the diaphragm filter press. The hydraulic filter press should choose a suitable position to place the hydraulic station to ensure the normal operation of the hydraulic station.
4. Place the filter plate according to the job requirements, and place the water inlet, cleaning and drainage pipes. It is equipped with a filter pressure display and a return channel to control the filter pressure. In the case of the diaphragm kneading type, place the compressed air line.
5. Diaphragm filter press, the oil tank of the hydraulic station is equipped with clean 20-40 hydraulic oil, and the operating temperature is -5 degrees Celsius; if the ambient temperature is low, the hydraulic oil with similar viscosity and low freezing point can be used. 80-100 mesh screen to increase hydraulic oil.
