Description

Technical Field

[0001] The utility model belongs to the field of filter presses of filtering equipment, and relates to a material distribution hole cloth clamp for a corner hole feeding filter plate. Background Art

[0002] The filter press is the main filtering equipment for solid-liquid separation. The filter cloth is the filter medium installed on both sides of the filter plate of the filter press. When working, the filter plate frame presses the filter cloth tightly, and a closed filter chamber is formed between two adjacent filter cloths. The material enters the filter chamber through the feed hole under the pressure of the feed pump, and the filter cloth intercepts the particles in the material to form a filter cake in the filter chamber.

[0003] The applicant proposed "Combined filter plate with corner hole feeding type in cavity part of parallel filter chamber and corresponding parallel filter chamber" with authorization number CN216778023U. By arranging double-chamber distribution holes (commonly known as single-chamber feed holes) in the corner recess (cavity part) of the filter plate adjacent to the main feed channel hole, the material is simultaneously and quickly and evenly diverted from the main feed channel to the filter chambers on both sides through the double-chamber feed branch holes. During use, the materials in some industries contain high-hardness particles. When the materials are poured into the filter chamber, they repeatedly impact the filter cloth around the distribution holes and the opposite area, causing the filter cloth to wear and material leakage. This not only affects the filtering effect, but also causes high production costs, high maintenance frequency, and reduced production efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the deficiencies existing in the above-mentioned background technology and to provide a corner hole feed filter plate distribution hole cloth clamp.

[0005] The corner hole feed filter plate distributor clamp comprises: a main body A, a main body B, and bolts. The main body A and the main body B have the same appearance. The main body is in the shape of a truncated cone and is hollow inside. A fixing platform is arranged on the inner side of the top of the main body. A bolt countersunk hole coaxial with the main body A is arranged on the fixing platform of the main body A, and a threaded hole coaxial with the main body B is arranged on the fixing platform of the main body B. A long strip hole is arranged on the side of the main body as a discharge hole. The bolt is a hexagon socket bolt.

[0006] Preferably, a convex ring is provided on the bottom surface of the main body, and the outer diameter of the convex ring matches the inner diameter of the distribution hole on the feed filter plate; during installation, the convex ring is inserted into the distribution hole, so that the corner hole feed filter plate distribution hole clamp is firmly installed and will not move.

[0007] Preferably, there are two elongated discharge holes arranged on the side of the main body, so that the discharge is more uniform.

[0008] The two main bodies of the corner hole feed filter plate dividing hole cloth clamp of the utility model are symmetrically arranged on both sides of the feed filter plate dividing hole, the convex ring is inserted into the dividing hole, the bottom surface of the round table is buckled on the feed filter plate, and bolts are passed through the bolt countersunk holes of the main body A and connected to the threaded holes of the main body B to fix the two main bodies and clamp the filter cloth; the nuts of the bolts are sunk into the bolt countersunk holes, the surface of the corner hole feed filter plate dividing hole cloth clamp is smooth and not easy to adhere to the filter cake; the material flows out from the long strip hole-shaped discharge holes on the side of the main body, the material diversion and circulation effect is good, and the filter cake is well formed; the material impacts the inner cavity of the main body but does not impact the filter cloth on the opposite side, thereby improving the service life of the filter cloth.
