Double-in-and-out chamber type filter plate assembly and corresponding double-in-and-out chamber type automatic filter press

Abstract

The invention discloses a double-in-and-out compartment type filter plate assembly and a corresponding double-in-and-out compartment type automatic filter press. The filter plate assembly comprises an upper single-lug feeding filter plate, a cloth clamping distributor, a trapezoidal double-lip sealing ring and a pull plate deviation rectifying spring washer, wherein the innovative points are as follows: a single-lug-hole two-way feeding mode is innovated, so that the area occupied by a feeding hole on a filter plate is reduced, and the feeding uniformity is improved; secondly, an orifice mounting type trapezoidal double-lip sealing ring is innovated, so that the area of the filter plate occupied by a sealing groove is reduced, and the high-pressure automatic sealing performance is improved; thirdly, the elastic rubber pads are additionally arranged to automatically correct the perpendicularity deviation of the filter plates, so that the peripheral filter frames are consistently sealed after the adjacent filter plates are pressed in parallel; and finally, the double-in-and-out characteristics of single-hole two-way feeding, double-hole one-way water or gas inlet and double-hole one-way undercurrent liquid outlet are achieved. According to the double-in-and-out compartment type automatic filter press, by using the filter plate assembly, various technical problems of low single-in-out efficiency, large occupied area of double feeding holes and sealing grooves, liquid leakage caused by the fact that the lower end of the filter plate is not pressed tightly due to self-inclination of the pull plate and the like are comprehensively solved, and therefore, the effects are significant.

Description

technical field [0001] The invention belongs to the technical field of van-type automatic filter press (patent classification number B01D25 / 12), and relates to a van-type filter plate assembly (filter plate and its accessories). Background technique [0002] The filter press is a pressurized filtration equipment with multiple filter chambers intermittently operated; the box filter press is a filter equipment composed of a plurality of box filter plates and filter cloths arranged alternately to form a filter room; the box automatic filter press The machine is a box-type filter press that integrates machinery, electricity, and hydraulics and is intelligently controlled by PLC; it mainly consists of a frame, a pressing mechanism, a box-type filter mechanism, a plate pulling mechanism, a cloth washing mechanism, and a liquid-contacting flap mechanism. , hydraulic drive mechanism, PLC program control system and other parts; suitable for solid-liquid separation of various suspensi...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to overcome the multiple defects of the existing parallel feed chamber filter plate assembly, and comprehensively solve the low efficiency of single in-out, double-hole one-way feed type feed hole and fluid hole end sealing groove occupying a relatively small area of ​​the filter plate. Large, filter plate support point eccentric pull plate self-tilts, so that the lower end of the filter plate is not pressed tightly and leaks, and other technical problems, provide a double-inlet box-type filter plate assembly with the characteristics of spring pad deviation correction and double-lip sealing and the corresponding double In and out of the box-type automatic filter press; elastic gasket correction - refers to the use of elastic rubber pads to automatically correct (correct) the verticality deviation of the filter plate, double lip seal - refers to the trapezoidal double lip high pressure automatic sealing ring installed at the orifice, double In and out—refers to the way of single-hole two-way feeding, double-hole one-way water or gas inlet, and double-hole one-way dark outflow.
