Bidirectional in-out multifunctional filtering mechanism and corresponding high-efficiency large chamber type filter press

Abstract

The invention discloses a bidirectional in-out multifunctional filtering mechanism and a corresponding high-efficiency large chamber type filter press. The filtering mechanism comprises head and tail single-face filtering plates, a bidirectional inlet and outlet filtering plate, a multifunctional material passing matching plate, a complete set of filtering cloth, a cloth clamping distributor, a hole end lip-shaped sealing ring, a filtering plate supporting handle and all inlet and outlet function external pipelines. According to the innovative scheme, a double-hole two-way parallel feeding mode, a single-hole two-way undercurrent liquid outlet mode and a single-hole alternate high-pressure water or gas inlet washing, back flushing and blow-drying mode are adopted, various functional holes are formed in a filter plate and a matching plate of the filter plate, and a machine tail movable type high-pressure hose is additionally arranged. According to the high-efficiency large chamber type filter press, the filtering mechanism is used, and meanwhile, relevant thrust plate and pressing plate inlet and outlet holes are correspondingly improved; materials are quickly and uniformly distributed to the filter chambers in two directions through the double feeding main channels, and filtrate quickly flows out from the two ends of the single-hole bidirectional undercurrent main channel; the technical problems that one-way parallel feeding is slow and not uniform enough, and one-way undercurrent liquid outlet is slow are comprehensively solved, and the effect is remarkable.

Description

technical field [0001] The invention belongs to the technical field of large box filter presses (patent classification number B01D25 / 12), and relates to a two-way in-out large box filter mechanism. Background technique [0002] A filter press is a multi-chamber intermittently operated pressurized filtration equipment. The concave part of the adjacent filter plates sandwiching the filter cloth constitutes a filter chamber; a chamber filter press is composed of multiple chamber filter plates, filter Filter equipment in which cloth and matching plates are arranged alternately to form a filter room; large filter press refers to a filter press with an effective filter area of ​​750 m² or more, a filter plate size of 2000mm×2000mm, and a length of 13m or more (exceeding the length of an international standard container); It is composed of frame, pressing mechanism, box filter mechanism, pulling plate mechanism, cloth washing mechanism, liquid-contacting flap mechanism, hydraulic d...
