Description

Technical Field

[0001] The invention belongs to the technical field of solid-liquid separation, and in particular relates to a combined filter press filter plate. Background Art

[0002] At present, filter presses have been widely used in various industries for material filtration and dehydration. They use a certain number of filter plates to be tightly arranged in a row under the action of strong mechanical force. Filter chambers are formed between the filter plates. The filter material is sent into the filter chamber under strong positive pressure. The solid part of the filter material entering the filter chamber is intercepted by the filter cloth to form a filter cake, and the liquid part passes through the filter medium and is discharged from the filter chamber, thereby achieving the purpose of solid-liquid separation.

[0003] In order to prevent the filter plates from being deformed and damaged due to the force applied to the filter plates and the channels from being blocked, it is necessary to set bosses on the filter plates. The concave space designed between the two filter plates forms a chamber, which supports the filter cavities of the filter plates and prevents them from being damaged under the pressure of filter pressing and dehydration.

[0004] In traditional processes, the bosses on filter plates are positioned according to the pressure they withstand. This is typically achieved through integrated processing. To address the varying pressures experienced during filter press dehydration, filter plates with varying numbers of bosses must be manufactured to meet the demands of various filter presses. Manufacturing filter plates requires molds, and multiple molds are required for various filter plate models. This increases production costs, extends production cycles, and complicates production management, hindering timely response to market demand.

[0005] Therefore, how to provide a combined filter plate with a simple structure and the ability to adjust the number of bosses has become a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0006] In view of this, the present invention provides a combined filter press filter plate, which has a simple structure and is easy to install. By designing the filter plate and the boss separately, the number of bosses can be reasonably adjusted according to the needs of dehydration and filtration to meet different filtration requirements.

[0007] In order to achieve the above-mentioned objectives, the present invention adopts the following technical solutions: a combined filter press filter plate, comprising a filter substrate, a boss structure and a filter plate handle, the boss structure comprising a top support platform, a boss base and a shield, the top support platform is rotatably connected to the boss base, a connecting shaft is provided at the center position of the top support platform, a return spring is mounted on the connecting shaft, the return spring is fixedly connected to the top support platform, and is used for returning the top support platform after rotation, a buffer structure is provided at the bottom of the boss base, a rotation locking mechanism is provided in the boss base, the connecting shaft is fixedly connected to the rotation locking mechanism, the shield is conically arranged, and the shield is arranged on the outer wall of the boss base, the surface of the filter substrate is evenly arranged with boss mounting grooves, the boss structure is installed in the boss mounting grooves, and the filter plate handle is inserted on both sides of the filter substrate.
