Description

Technical Field

[0001] The utility model relates to the field of filters, in particular to a tray structure used for a filter element seat of a filter. Background Art

[0002] In the filtering equipment, the filter cartridge and the filter element seat are both key components.

[0003] The filter cartridge is a structure used to accommodate the filter element. It is usually composed of a shell with a filter element installed inside. Its function is to protect the filter element, support the filter element, and provide an interface for connecting the pipeline.

[0004] The filter seat is a component installed at the bottom of the filter cartridge to fix and support the filter element. The design of the filter seat can vary according to the type and size of the filter element, ensuring that the filter element can be properly installed inside the filter cartridge and providing stable support.

[0005] For example, the patent document with patent number 201210458015.3 discloses an integrally formed filter cartridge, which includes a filter cartridge, a filter element tray arranged at the bottom of the filter cartridge, and a filter element seat arranged on the filter element tray, wherein the filter element tray and the filter element seat are threadedly connected; the filter element tray and the filter cartridge are separately arranged; a through hole is arranged at the bottom of the filter cartridge, a threaded column matching the through hole is arranged at the lower part of the filter element tray, a nut matching the threaded column is arranged on the threaded column, and the filter element tray is fixed to the filter cartridge by the nut; a positioning block is arranged on the outer side of the filter element tray, and the filter cartridge is provided with a positioning groove matching the positioning block; a top column is arranged on the filter element tray, and the top column abuts against the filter element seat.

[0006] In the above scheme, after the fluid to be filtered is introduced into the interior through the inlet at the bottom of the filter cartridge, it needs to pass through the flow channel between the outer edge of the filter element seat and the inner wall of the filter cartridge, and then enter the filter element (usually installed on the filter element seat) for filtration, and finally reach the water outlet of the filter cartridge through the water outlet of the filter element for discharge.

[0007] However, the above solution still has the following problems:

[0008] 1) During the filtration process, the flow channel between the outer edge of the filter element seat and the inner wall of the filter cartridge is affected by the filter element seat, and the size of the flow channel is limited, resulting in a small flow rate of the fluid introduced, and the rated filtration power of the filter element cannot be fully utilized.

[0009] 2) A flow channel needs to be set between the water outlet of the filter element and the water outlet of the filter cartridge. Generally, the water outlet of the filter element and the water outlet of the filter cartridge are connected by a pipeline to realize the transmission of the fluid. However, this solution is difficult to meet the fluidity and pressure drop of the fluid at the same time.

[0010] If the fluidity is insufficient, it is impossible to ensure that the fluid can flow smoothly from the water outlet of the filter element to the water outlet of the filter cartridge, and the fluid may be blocked and accumulated, affecting the normal operation of the system. If the pressure drop of the fluid during the flow process is too large, the pump needs to provide additional kinetic energy, and low energy consumption cannot be achieved.

[0011] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content
