Box type filter press with automatic vibration and beating device

Abstract

The invention discloses a box type filter press with automatic vibration and beating device. The box type filter press comprises two sets of support plates arranged in parallel, and a support frame and a liquid collection tank are arranged between the two sets of support plates. The front side wall of the liquid collection tank is provided with the vibration and beating device. The top of the support frame is provided with a passive extrusion plate, a filter cake and an active extrusion plate sequentially from left to right in a clamping connection way, the passive extrusion plate is fixed onthe left support plate, the right side of the active extrusion plate is provided with a hydraulic push rod, the right end of the hydraulic push rod is fixed on the right support plate, and the right side wall of the right support plate is provided with a water delivery pipe. The structure of the box type filter press is reasonable in design, can achieve effects of cleaning material residues and dye residues through an electric sliding block driving a brush to make reciprocating movement in the liquid collection tank, and reduces influences of waste gas generated in a press filtration process on operators by using a gas collection hood and a suction pump communicating with the gas collection hood to extract the waste gas generated in the press filtration process into a gas purification device.

Description

technical field [0001] The invention relates to the technical field of filter presses, in particular to a box-type filter press with an automatic rapping device. Background technique [0002] The filter mechanism is composed of a filter plate, a filter frame, a filter cloth, and a squeeze diaphragm. Both sides of the filter plate are covered by filter cloth. When a squeeze diaphragm is required, a set of filter plates is composed of a diaphragm plate and a side plate. The two sides of the base plate of the diaphragm plate are covered with rubber diaphragms, the outside of the diaphragm is covered with filter cloth, and the side plates are ordinary filter plates. The material enters each filter chamber from the feed hole on the thrust plate, and the solid particles are trapped in the filter chamber because the particle size is larger than the pore size of the filter medium (filter cloth), and the filtrate flows out from the outlet hole under the filter plate. When the filter...

Problems solved by technology

[0003] The filter press is an important equipment widely used in chemical, petroleum, pharmaceutical, food and other industries to achieve solid phase and liquid phase separation. After the existing filter press washes the pigment, the solid content of the pigment between the filters is 8%- Between 15%, water accounts for 85%-92%, and it takes more than 30 hours to evaporate the water during the drying process, because the quality of the pigment is greatly reduced due to the long drying time

[0004] In the process of pressing the filter, part of the dye in the filter cake will fall into the inner cavity of the effusion tank along with the extruded water, and the slag will also fall into the effusion tank. The traditional filter press, Most of them manually clean up the slag and the dye attached to the inner cavity of the effusion tank, which increases the labor intensity of the operator
