Description

Technical Field

[0001] The utility model relates to the field of bag filters, in particular to an upper cover component in a bag filter. Background Art

[0002] Bag filter is a common industrial filter. Its working principle is to use filter bags to filter fluids, filter out impurities, particles and other substances, so as to achieve the purpose of purifying fluids. Bag filters are usually composed of filter housings, filter bags, inlet and outlet pipes and support frames.

[0003] Specifically, the working process of the bag filter is as follows:

[0004] Feed: The fluid enters the bag filter housing through the inlet pipe.

[0005] Filtration: When the fluid passes through the filter bag, the pores on the filter bag filter out impurities, particles and other substances, thereby achieving the purpose of purifying the fluid. Discharge: The fluid filtered by the filter bag flows out from the outlet pipe of the bag filter, achieving the purpose of purification.

[0006] For example, the patent document with patent number 202321481069.1 discloses a low-residue bag filter structure, including a filter housing, a guide assembly and a filter assembly; the filter housing includes a main barrel, on which a liquid inlet and a liquid outlet are provided; the guide assembly includes a filter upper seat and a filter lower seat arranged in the main barrel, and a plurality of water-saving filling pipes are provided between the filter upper seat and the filter lower seat, and a water collecting pipe is provided on the outer side of the water-saving filling pipe, and the filter assembly is installed between the water-saving filling pipe and the water collecting pipe, and the bottom end of the water collecting pipe is connected to a first outlet opened on the filter lower seat, and a water collecting tray is provided below the filter lower seat, and a second outlet connected to the liquid outlet is provided on the water collecting tray; the filter assembly includes a filter material frame and a filter medium, the bottom of the filter material frame is fixed in the positioning groove of the filter lower seat, and the top of the filter medium is fixed to the filter upper seat through a filter bag pressure plate.

[0007] The above technical solution provides a flow guide assembly for installing the filter assembly inside the filter, so that the flow path of the liquid is restricted to the space between the water-saving filling pipe and the water collecting pipe, thereby effectively preventing the liquid from entering other structures inside the filter.

[0008] However, the above technical solution still has the following defects:

[0009] The water inlet of the filter seat is a closed structure opened inside the filter seat. It will generate stress during processing and may cause structural damage if not handled properly.

[0010] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0011] The utility model aims to provide an upper cover assembly in a bag filter to solve the defects in the prior art.

[0012] The above technical objectives of the utility model are achieved through the following technical solutions:

[0013] An upper cover assembly in a bag filter comprises an upper mounting seat, wherein the upper mounting seat comprises a disc-shaped upper mounting seat body, and a center hole, a plurality of upper water holes and a water inlet circular hole are opened on the upper mounting seat body;

[0014] The center hole is opened in the middle position of the upper mounting seat body, the upper mounting seat is connected to the pressure plate through the center hole, and a plurality of upper water holes are arranged along the outer edge of the upper mounting seat body, and the main body of the upper water holes is an open structure; the water inlet circular hole is arranged at a position between the center hole and the upper water holes, and the upper mounting seat is connected to the top of a bag filter through the water inlet circular holes.

[0015] Furthermore, the upper water holes are evenly distributed along the outer edge of the upper mounting seat, and the circular water inlet holes are distributed on the upper mounting seat with the center hole as a symmetrical point.

[0016] Furthermore, the back side of the upper mounting seat is the connection surface with the bag filter, and the inner wall of the water inlet circular hole is provided with a connecting thread. The bag filter is rotated and screwed into the water inlet circular hole from the back side of the upper mounting seat and is locked and fixed by the connecting thread.

[0017] Furthermore, the circular water inlet holes are evenly distributed along the inner side of the upper mounting seat, and the circular water inlet holes and the upper water through holes are staggered on the upper mounting seat.

[0018] In summary, the utility model has the following beneficial effects:

[0019] By adopting an open upper water hole as the main structure, the stress generated during processing can be guided out by the open structure, thereby avoiding structural damage that is easy to occur during processing, reducing the processing difficulty of the upper cover assembly, and improving the yield rate.
