Description

Technical Field

[0001] This utility model relates to the technical field of ferric phosphate wastewater treatment devices, specifically to a filter element for ferric phosphate wastewater treatment that is easy to install. Background Technology

[0002] Lithium iron phosphate (LFP) batteries are an important resource in the new energy field and a crucial material for the production of electric vehicle batteries. The manufacture of LFP batteries involves a complete process that requires the use of LFP battery electrolyte filters.

[0003] In the process of realizing this utility model, the inventors discovered the following problems with the prior art: the filter element may be located at the bottom, inside or in a low position of the equipment, which makes it inconvenient for maintenance personnel to replace and install it due to the limited angle. Utility Model Content

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an easy-to-install iron phosphate wastewater treatment filter element, which can effectively solve the problems in the existing technology.

[0006] Technical solution

[0007] This utility model provides an easy-to-install iron phosphate wastewater treatment filter element, including an outer cylinder, a sealing cap, and a connecting plate fixed inside the outer cylinder. A positioning head frame, a screw fixing seat, and a bracket are fixed on the inner wall of the connecting plate. The top of the bracket is fixedly connected to a collar, and a screw is fitted in the middle of the collar. A filter assembly is fixed to the inner side of the outer cylinder, and the filter assembly includes a positioning tail frame. Filter cotton is fitted between the positioning head frame and the positioning tail frame. The positioning head frame is fixed to the inner side of the outer cylinder, and a circular hole is opened in the middle of the outer cylinder. The screw is disposed in this circular hole and is fixedly connected to the outer cylinder by a locking ring.

[0008] Furthermore, the inner wall of the outer cylinder and the outer wall of the connecting disc are engaged and fixed by a threaded structure.

[0009] Furthermore, a filter screen is fixed to the outside of the filter cotton, and annular grooves are provided in the middle of the outer sides of both the positioning head frame and the positioning tail frame.

[0010] Furthermore, the positioning head frame, the lead screw fixing seat, and the bracket are concentrically arranged, and the bracket is located inside the positioning head frame, and the bracket is a multi-set inclined plate structure.

[0011] Furthermore, the connecting plate has a circular hole structure in the middle and on the outer side of the middle. The screw fixing seat is fixed outside the circular hole in the middle. The sealing cover has an inlet pipe fixed in the middle and an outlet pipe fixed on one side of the middle. The end of the inlet pipe is connected to the circular hole in the middle of the connecting plate, and the circular hole on the outer side of the middle of the connecting plate is connected to the inner tube.

[0012] Furthermore, the length of the inner tube is less than the length of the filter cotton, and the inner tube is located on the outside of the filtration assembly.

[0013] Beneficial effects

[0014] This utility model, through its combined structure of outer cylinder and connecting plate, allows the user to fix the filter assembly onto the connecting plate during assembly. Liquid is added through the outer inlet pipe, enters the filter assembly through the screw fixing seat and bracket, and after filtration, flows out from the filter assembly, merges into the space between the outer cylinder and the filter screen, and flows out through the inner pipe, sealing cap, and outlet pipe, thus achieving the filtration function. The collar-screw-locking ring structure set inside the filter assembly allows the user to engage the locking ring with the screw after the outer cylinder and connecting plate are fixed. The end of the screw is then fixedly connected to the bracket and connecting plate through the screw fixing seat, thereby achieving overall fixation from the inside. This, combined with the external structure, enables rapid assembly and fixation.

[0015] This device can be divided into three parts: first, a fixed structure consisting of a sealing cover and a connecting plate; second, a middle filter assembly; and third, a fixed structure consisting of an outer cylinder and a positioning tail frame. During assembly, the filter screen and filter cotton structure inside the filter assembly can be locked inside the positioning head frame and positioning tail frame. Therefore, during use, the filter cotton and filter screen structures are separate structures, which can be easily disassembled and replaced by the user after a certain period of use.
