The filter press is placed on a flat concrete foundation. The filter mechanism of the sand washing filter consists of a filter plate, a filter frame, a filter cloth, and a pressing diaphragm. The two sides of the filter plate are covered with the filter cloth. composition. The two sides of the base plate of the diaphragm plate are covered with a rubber diaphragm, and the outer side of the diaphragm is surrounded by the filter plate of the filter cloth side plate. Diaphragm filter press is a filter press with an elastic membrane installed between the filter plate and the filter cloth. When the feeding is completed during the operation, the high-pressure fluid or gas medium can be injected into the diaphragm plate, and the filter cake is further dehydrated and squeezed. The thrust plate at the feed end should be fixed. After the support end is positioned, lock it with two nuts. There are no anchor bolts or anchor bolts. There is a proper gap between the nut washer and the foot. The front corrects the verticality of the large plane between the beam and the thrust plate. The layout shall be held by the construction engineer according to the configuration load, and the anchor rod shall be re-grouted at the reserved hole position. There should be sufficient filter pressure around the operating and maintenance space. The hydraulic filter press should choose a suitable location to arrange the hydraulic station. Filter plates, wash tubes and drains. Equipped with filter pressure indicator and return channel to control the filter pressure. In the environment where the diaphragm is squeezed, a compression atmosphere pipeline is set. Hydraulic filter press and hydraulic station oil tank are filled with clean hydraulic oil, such as hydraulic oil with low ambient temperature, similar viscosity, and low condensation point. When the hydraulic pressure is applied, the pressure gauge rises and there is no leakage in the hydraulic system. The pressure of the hydraulic station should be adjusted accurately according to the size of the model. If it is found that the oil storage capacity of the oil tank is insufficient after the test, it must be supplemented.
