Description

Technical Field

[0001] The utility model relates to the field of bag filters, in particular to a lower cover assembly for bag filters. 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 on the filter lower seat is a closed structure opened inside, which 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 purpose of the utility model is to provide a lower cover assembly for 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] A lower cover assembly for a bag filter comprises a lower mounting seat, wherein the lower mounting seat comprises a disc-shaped lower mounting seat body, and a lower water through hole, a positioning groove and a water outlet hole are arranged on the lower mounting seat body;

[0014] The plurality of lower water holes are evenly distributed along the outer edge of the lower mounting seat body. The body of the lower water holes is an open structure. A plurality of positioning grooves are provided on the upper surface of the lower mounting seat body, and are respectively connected to the bottom of a bag filter through the positioning grooves. Water outlet holes are provided in the positioning grooves. The bottom of the bag filter is fixedly mounted in the lower mounting seat through the positioning grooves. The water outlet holes are connected to the bottom of the bag filter and are used to discharge the fluid filtered by the bag filter.

[0015] Furthermore, the lower water holes are evenly distributed along the outer edge of the lower mounting seat body, and the positioning grooves and the water outlet holes are symmetrically distributed on the lower mounting seat with the center point of the lower mounting seat as a point.

[0016] Furthermore, the lower surface of the lower mounting seat body has a lower mounting seat boss protruding downward, and an external thread is provided on the outer surface of the lower mounting seat boss. The lower mounting seat body is installed inside the bag filter barrel through the lower mounting seat boss, and a sealing groove is provided at the connection between the lower mounting seat boss and the lower mounting seat body, and the sealing groove is used to place a sealing ring.

[0017] Furthermore, the water outlet is located in the boss of the lower mounting seat.

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

[0019] By adopting an open lower 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 and improving the yield rate.
