Hydraulic drive type filter press and filter pressing method

Abstract

The invention discloses a hydraulic drive type filter press and filter pressing method. The hydraulic drive type filter press comprises a frame, an oil tank, an oil pump, a hydraulic cylinder, a feeding port valve, a discharging port valve and a liquid outlet valve, the oil tank and the oil pump are installed outside the top end of the frame, and the oil tank, the oil pump and the hydraulic cylinder are communicated through oil pipes. By arranging a motor, a push plate, a pressing plate and a stirring rod, the push plate drives the pressing plate to synchronously rotate through the stirring rod, the stirring rod stirs and crushes a filter cake subjected to filter pressing, and the crushed filter cake flows out of a discharge port; and when the output shaft of the hydraulic cylinder retracts, certain friction force between the stirring rod and the pressing plate makes the pressing plate move synchronously, the pressing plate moves to a certain position and stops, and the stirring rod is drawn out from a through groove in the surface of the pressing plate, so that residues adhered to the surface of the stirring rod are scraped, the problem that filter cakes subjected to filter pressing of an existing filter press are difficult to take out can be effectively solved, and the filter press is faster and more efficient than manual cleaning.

Description

technical field [0001] The invention belongs to the technical field of filter presses, and in particular relates to a hydraulically driven filter press and a filter press method. Background technique [0002] The filter press uses a special filter medium to apply a certain pressure on the object to make the liquid dialysis out. It is a kind of mechanical equipment commonly used for solid-liquid separation. It was used in chemical production at the beginning of the 18th century, and is still widely used in chemical, pharmaceutical, metallurgy, dyestuff, food, brewing, ceramics and environmental protection industries. However, there are still some problems in the actual use of existing filter presses. After the filter press is completed, a filter cake will be formed, and the filter cake will adhere to the surface of the filter tank and filter plate under the high pressure of the filter press, and manual cleaning is required. It is not ideal. On the other hand, improper operat...
