Abstract

The utility model belongs to the field of solid-liquid separation equipment, in particular to a filter disc component of a tilting disc vacuum filter; in order to solve the inconvenient and plane yielding problem of the filter plate dismantlement clearance that prior art exists, the utility model provides a hem piecemeal and press beam combination filter plate structure adopts polylith hem filter plate to add the filter plate that the press beam concatenation of punching a hole made up into single filter disc, and no bolt-up, piecemeal hem filter plate plane degree is easily guaranteed and light quick detachable clearance.

Description

Folding blocking and pressing beam combined filter plate structure

Technical Field

The utility model belongs to the solid-liquid separation equipment field especially relates to tilting pan vacuum filter's filter disc part.

Background

The filtering medium (filtering cloth) arranged on the filtering disc of the tilting-disc vacuum filter is supported by the metal punched filtering plate, the area of a single filtering disc reaches 8 square along with the large-scale development of equipment, so that the weight of the filtering plate of the original single filtering disc can reach 120-150 Kg, and the disassembly and the cleaning are inconvenient. Along with the diversification of treatment materials, a lot of solid-liquid separation materials are recrystallized or subjected to secondary reaction in the inner cavity of the filter disc and the pores of the filter plate to form scaling blockage, so that the disassembly and cleaning work is frequent, and the disassembly and cleaning work of the filter plate usually damages the flatness of the filter surface to reduce the performance of equipment. The filter plate is usually fastened on a cavity bottom bracket of the filter disc by bolts, the connecting bolts are frequently bitten and broken when the filter plate is disassembled in the filter in the prior production and operation, and the scaling of materials at the threaded connection part is also a main factor. The convenience of filter plate disassembly and flatness stability are related to the performance and the driving rate of the filter, so a filter plate structure with the convenience of disassembly is required to replace the filter plate structure.

SUMMERY OF THE UTILITY MODEL

In order to solve the inconvenient and plane yielding problem of the filter plate dismantlement clearance that prior art exists, the utility model provides a hem piecemeal and press beam combination filter plate structure adopts polylith hem filter plate to add the filter plate that the press beam concatenation of punching a hole made up into single filter disc, and no bolt-up, piecemeal hem filter plate plane degree is easily guaranteed and light quick detachable clearance.

The utility model provides a technical scheme that its technical problem adopted is: a folding block and pressing beam combined filter plate structure comprises a plurality of sub-filter plates and pressing beams which form an integral filter plate, wherein the pressing beams are arranged between the sub-filter plates; the sub-filter plate consists of a butt strap, a folded and punched plate and a folded rib plate, and the press beam consists of a butt strap, a folded rib plate, a punched ribbon plate and a press sheet.

Holes are fully distributed on the folded edge punching plate of the filter dividing plate to form liquid flow passages; the folded rib plate is arranged in the middle of the folded punching plate to increase rigidity; the lap plates are arranged below the peripheral hems of the hem punching plates, the lap plates on the compression beam sides of the sub-filter plates are arranged right below the compression sheets on the compression beam sides, and the lap plates are used for fixing the sub-filter plates.

Holes are fully distributed on the punching ribbon board of the pressing beam to form a liquid flow channel; the folded rib plate is arranged in the middle of the punched batten to increase rigidity; the lap plates are positioned below the folded edges at the two ends of the punching strip plate and used for fixing the pressing beam; the pressing sheets are arranged below the punching lath and on two sides of the folded rib plate and used for fixing the filter separating plate.

When the periphery of the filter cloth of the filter is compressed, downward pressure is also applied to the lap plates of the sub-filter plates and the pressing beams, so that the sub-filter plates and the pressing beams are fixed on the cavity bottom bracket of the filter disc, and the pressing beams transmit the downward pressure to the indirect compression edges of the sub-filter plates.

The utility model relates to a hem piecemeal and press beam combination filter plate structure realizes that the filter plate does not have the bolt-up, dismantles light not fragile purpose through above-mentioned mode.
