Problems solved by technology

In the existing hydraulic compression, the hydraulic station pushes the compression plate to compress the filter plate in one direction through the hydraulic cylinder components on the frame. Since the hydraulic cylinder components push and compress the filter plate in one direction, the output of one compression is low. , the same energy consumption will easily lead to energy waste
[0003] In order to improve the filter press effect, reduce the water content after the press filter, and improve the work efficiency, the current filter press is equipped with a spring mechanism between the main board and the sub-frame. However, the use of the spring mechanism makes this patent have the following disadvantages: 1) The spring mechanism is set between the main board and the sub-frame, which generates tension on the main board and the sub-frame on both sides. If too many springs are used, the resistance will be large during the filter pressing process, which will increase the workload of the hydraulic pressing device and reduce the efficiency. , less materials for one-time filter press, 2) Due to the different tension of each spring, th

Abstract

The invention relates to a plate-and-frame filter press which comprises a support, two cross beams and a hydraulic compressing device arranged on the support, wherein a push plate, a stop plate and a plate-and-frame group are arranged between the two cross beams, one side of each plate frame is in a plane structure, another side of each plate frame is a frame convex, each plate frame has a concave structure inside, one side of each plate frame plane is provided with a plate frame extruding balance beam, a spring and a small hydraulic cylinder are arranged between each plate frame and each plate frame extruding balance beam, a hydraulic oil opening is arranged on a small hydraulic cylinder body, the hydraulic oil opening is connected with a hydraulic oil support pipe, and a hydraulic oil branch pipe on each plate frame is communicated with a hydraulic oil main pipe on each plate frame. The position except a material inlet on the surface at one side of each plate frame is provided with an automatic filter cloth cleaning device. The plate-and-frame filter press is simple in structure, each plate frame can be synchronously pushed in the process of filter-press, the plate frames can be compacted with one another, the material can not be lost, the plate-and-frame filter press is high in filter-press efficiency, the workload of the hydraulic compressing device can be effectively reduced, each plate frame can not deform or be damaged, and the plate-and-frame filter press has a function for cleaning a filter cloth on line.

Description

Technical field [0001] The invention relates to a plate and frame filter press, which belongs to the technical field of solid-liquid separation equipment. Background technique [0002] The plate and frame filter press is a kind of intermittent solid-liquid separation equipment, which is light, flexible and reliable. It is composed of filter plates and filter frames arranged to form a filter chamber. Under the action of a feed pump, the material and liquid are transported to each The filter chamber separates the solid and liquid through the filter medium. Compared with other solid-liquid separation equipment such as centrifuges, the plate and frame filter press has the advantages of low investment, energy saving, and safety. It is widely used in chemicals, dyes, petroleum, ceramics, medicine, food, smelting and various industries. Sewage treatment etc. The compression method of the filter press has three forms: manual compression (small size), mechanical compression and hydrauli...
