Description

Technical Field

[0001] The utility model relates to the field of bag filters, in particular to a bag filter pressing plate assembly which is easy to install. Background Art

[0002] Bag filters are a common industrial filter. Their working principle is to filter fluids using filter bags, removing impurities, particles, and other substances, thereby purifying the fluid. Bag filters typically consist of a filter housing, filter bags, inlet and outlet pipes, and a supporting frame.

[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, which is provided with a liquid inlet and a liquid outlet; the guide assembly includes a filter upper seat and a filter lower seat arranged in the main barrel, and a number 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. 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 the 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 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, effectively preventing it from entering other structures inside the filter.

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

[0009] The filter medium and the filter screen upper seat need to be connected and fixed by a filter bag pressing plate respectively. When a large number of filter media are set, it takes a lot of time to install the filter bag pressing plate.

[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 bag filter pressing plate assembly that is easy to install, so as to solve the defects existing in the prior art.

[0012] The above technical objectives of the present invention are achieved through the following technical solutions:

[0013] A bag filter pressure plate assembly that is easy to install, comprising a pressure plate, wherein the pressure plate comprises a pressure plate body in a rounded triangular shape, and a water inlet, a connecting boss and a center hole are respectively provided on the pressure plate body;

[0014] The water inlet is arranged along the inner side of the corner of the pressure plate body, and the number of the water inlet is the same as that of the bag filter; one end of the water inlet is the fluid introduction end, and the other end of the water inlet extends downward and forms a pressure plate boss on the lower surface of the pressure plate body, and the pressure plate is connected to the upper cover plate of the bag filter through the pressure plate boss;

[0015] The center hole is set in the middle position of the pressure plate body, which is used to set the rotating connector. After the pressure plate and the upper cover plate are pre-installed, the center hole is opposite to the preset connection hole on the upper cover plate, and the rotating connector passes through the center hole and the connection hole in turn to connect and fix the pressure plate and the upper cover plate.

[0016] Furthermore, the center hole is a threaded hole, an inner connecting thread is provided on the inner wall of the center hole, and the connecting end of the rotary connector has an outer connecting thread that matches the inner connecting thread.

[0017] Furthermore, the connecting boss has a stepped limiting structure and is pre-installed on the upper cover plate through the stepped limiting structure.

[0018] Furthermore, the water inlets are symmetrically distributed with the central hole as the center.

[0019] In summary, the present invention has the following beneficial effects:

[0020] By adopting an integrated pressure plate assembly, the pressure plate assembly has the same number of connecting bosses as the bag filters, and can complete the pre-installation with all bag filters at one time. After the pre-installation is completed, the fixed installation can be completed by rotating the connecting piece, the installation process is simple and the installation efficiency is high.
