Description

Technical Field

[0001] The utility model belongs to the field of filter presses, and in particular relates to a hook structure of a filter press base. Background Art

[0002] Filter press is the main filtering equipment in the solid-liquid separation industry and is widely used in chemical, coal washing, food, environmental protection and sewage treatment industries. The commonly used filter press frame is mainly composed of the main beam, thrust plate, cylinder seat, etc. The filter elements are filter plates and filter cloth. The two ends of the main beam are set on the thrust plate and the cylinder seat, and the thrust plate and the cylinder seat are collectively called the machine seat.

[0003] The applicant's authorized patent "A filter press main beam fixing structure" authorization announcement number CN 205182288 U discloses a main beam fixing structure, where circular load-bearing protrusions, commonly known as hooks, are set on both sides of the machine base, and corresponding circular load-bearing shaft holes are opened in the main beam. The main beam load-bearing shaft holes and the machine base load-bearing protrusions are assembled to withstand tension. In the prior art, the machine base side panels and load-bearing protrusions are milled from thick metal plates, which is time-consuming and material-intensive to process, and the cost is too high. Utility Model Content

[0004] The utility model aims to provide a filter press base hook structure which is more convenient to process and saves more materials in view of the above-mentioned problems.

[0005] The utility model discloses a hook structure for a filter press base, wherein a circular hole is arranged on a side plate on the base, and a load-bearing protrusion is a stepped cylindrical shape, which is divided into a thin shaft end and a thick shaft end; the inner diameter of the circular hole arranged on the side plate is slightly smaller than the outer diameter of the thin shaft end of the load-bearing protrusion, the thin shaft end of the load-bearing protrusion is inserted into the circular hole of the side plate, the thin shaft end of the load-bearing protrusion and the circular hole of the side plate are interference fit, and the thick shaft end of the protruding side plate is assembled with the load-bearing shaft hole on the main beam.

[0006] The utility model has a hook structure for a filter press base, wherein the side plate is preheated first, and then the thin shaft end of the load-bearing protrusion is inserted into the circular hole of the side plate, and an interference fit is formed after cooling. The side plate and the load-bearing protrusion assembly are welded to the base and then machined. The utility model has a more convenient processing, saves more materials, and effectively reduces production costs. BRIEF DESCRIPTION OF THE DRAWINGS
