Description

Technical Field

[0001] The utility model relates to the technical field of electrolyte circulation cleaning, and particularly relates to a double-filter mechanism for circulating electrolyte. Background Art

[0002] Tungsten wire is a kind of fine wire made by forging and drawing tungsten bars or tungsten rods. It is a typical tungsten product. Due to its high melting point, good flexibility, large tensile strength, strong fatigue resistance, high temperature resistance, corrosion resistance and oxidation resistance, etc., it is deeply favored by the majority of diamond wire busbars and is often used in various fields. The preparation process of tungsten wire usually requires two processes: wire drawing and cleaning. After the tungsten wire is drawn, since some impurities (graphite milk) such as oxides will adhere to the surface of the tungsten wire, it is necessary to remove them through the cleaning process.

[0003] Existing cleaning equipment generally uses circulating electrolyte to clean tungsten wire, and a set of filters is added to the circulating electrolyte pipeline. The filters filter the electrolyte to ensure the cleaning effect of tungsten wire. However, because the cleaning equipment works for a long time (24 hours), the filtering effect of the filters will gradually decrease, and the filter element of the filters needs to be replaced. During the replacement process of the filter element, the cleaning equipment needs to be paused, which will cause the cleaning of tungsten wire to be paused and reduce the cleaning efficiency of tungsten wire. In view of the above problems, it is urgent to improve this. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a double-filter mechanism for circulating electrolyte that ensures the filtering effect and cleaning efficiency.

[0005] To solve the above technical problems, the utility model can adopt the following technical solutions:

[0006] A double-filter mechanism for circulating electrolyte includes a base, a main inlet pipe, a first filter, a second filter, a main outlet pipe and a circulation pump. The first filter, the second filter and the circulation pump are respectively installed on the base. The lower part of the first filter has a first inlet, the upper part has a first outlet, and first control valves are arranged at the first inlet and the first outlet. The lower part of the second filter has a second inlet, the upper part has a second outlet, and second control valves are arranged at the second inlet and the second outlet. One end of the main inlet pipe is respectively connected to the first inlet and the second inlet, one end of the main outlet pipe is respectively connected to the first outlet and the second outlet, and the other end is connected to the circulation pump.

[0007] In one embodiment, the first filter and the second filter have the same structure, and both include a filter cylinder and a cylinder cover. The bottom of the filter cylinder is fixed to the base, and the cylinder cover is hermetically covered with the top of the filter cylinder through a locking member.

[0008] In one embodiment, a gasket is provided between the cylinder cover and the filter cylinder.

[0009] In one embodiment, the locking member includes a locking rod and a locking handle. One end of the locking rod is rotatably connected to the side wall of the filter cylinder. A locking groove is formed in the side wall of the cylinder cover. The other end of the locking rod can be inserted into the locking groove and is threadedly connected to the locking handle.

[0010] In one embodiment, a plurality of the locking members are provided and are evenly spaced apart.

[0011] In one embodiment, a first pressure gauge is provided on the side wall of the first filter.

[0012] In one embodiment, a second pressure gauge is provided on the side wall of the second filter. Advantageous Effects

[0013] For the double-filter mechanism for circulating electrolyte of the present utility model, when cleaning tungsten wires, the electrolyte is circulated and transported by a circulation pump, and the electrolyte is filtered by the first filter or the second filter. When it is necessary to disassemble, clean or replace the filter element of the first filter or the second filter after working for a period of time, the first control valve and the second control valve can be controlled without stopping the machine, so as to realize the switching work of the first filter and the second filter, thereby ensuring the filtering effect of the electrolyte.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0021] Please refer to Figure 1 , a double-filter mechanism for circulating electrolyte, comprising a base 100, a liquid inlet main pipe 200, a first filter 300, a second filter 400, a liquid outlet main pipe 500, and a circulation pump 600. The first filter 300, the second filter 400, and the circulation pump 600 are respectively installed on the base 100; the lower part of the first filter 300 has a first liquid inlet 310, the upper part has a first liquid outlet 320, and a first control valve 330 is provided at the first liquid inlet 310 and the first liquid outlet 320. The lower part of the second filter 400 has a second liquid inlet 410, the upper part has a second liquid outlet 420, and a second control valve 430 is provided at the second liquid inlet 410 and the second liquid outlet 420; one end of the liquid inlet main pipe 200 is respectively connected to the first liquid inlet 310 and the second liquid inlet 410, one end of the liquid outlet main pipe 500 is respectively connected to the first liquid outlet 320 and the second liquid outlet 420, and the other end is connected to the circulation pump 600.

[0022] Specifically, in this embodiment, one end of the liquid inlet main pipe 200 is connected to the first liquid inlet 310 and the second liquid inlet 410 of the first filter 300 and the second filter 400 respectively, and one end of the liquid outlet main pipe 500 is connected to the first liquid outlet 320 and the second liquid outlet 420 of the first filter 300 and the second filter 400 respectively. The other end of the liquid outlet main pipe 500 is connected to the circulation pump 600. The circulation pump 600 circulates and transports the electrolyte. During the transportation process, the electrolyte will be filtered by the first filter 300 or the second filter 400, so as to ensure the cleaning effect of the electrolyte on the tungsten wire.

[0023] During actual operation, only one of the first filter 300 and the second filter 400 needs to be opened. After the first filter 300 is used for filtration for a period of time, it needs to be disassembled, cleaned or the filter element needs to be replaced. At this time, the second control valve 430 at the second liquid inlet 410 and the second liquid outlet 420 can be opened to connect the second liquid inlet 410 with the liquid inlet main pipe 200 and the second liquid outlet 420 with the liquid outlet main pipe 500. At the same time, the first control valve 330 at the first liquid inlet 310 and the first liquid outlet 320 is closed to disconnect the first liquid inlet 310 from the liquid inlet main pipe 200 and the first liquid outlet 320 from the liquid outlet main pipe 500, so as to realize the switching between the first filter 300 and the second filter 400. After switching, the second filter 400 filters the electrolyte, and the first filter 300 can be disassembled, cleaned or the filter element can be replaced to ensure the cleaning effect on the tungsten wire. Moreover, when switching between the first filter 300 and the second filter 400, there is no need to stop the cleaning equipment, so as to ensure the cleaning efficiency of the tungsten wire.

[0024] On the contrary, when the second filter 400 is used for filtration for a period of time and needs to be disassembled, cleaned or the filter element needs to be replaced, the first control valve 330 at the first liquid inlet 310 and the first liquid outlet 320 can be opened, and the second control valve 430 at the second liquid inlet 410 and the second liquid outlet 420 can be closed to connect the first liquid inlet 310 with the liquid inlet main pipe 200, disconnect the second liquid inlet 410 from the liquid inlet main pipe 200, connect the first liquid outlet 320 with the liquid outlet main pipe 500, and disconnect the second liquid outlet 420 from the liquid outlet main pipe 500, so as to realize the switching between the first filter 300 and the second filter 400. Similarly, the cleaning effect and cleaning efficiency of the tungsten wire can be ensured. Moreover, during the switching process, only the first control valve 330 and the second control valve 430 need to be operated, so that the switching process runs smoothly and the operation is simple and convenient.

[0025] Of course, for safe production, a first pressure gauge 700 is provided on the side wall of the first filter 300, and a second pressure gauge 800 is provided on the side wall of the second filter 400. The internal pressures of the first filter 300 and the second filter 400 can be monitored in real time through the first pressure gauge 700 and the second pressure gauge 800 to ensure the overall safety of the cleaning equipment.

[0026] Please refer to Figure 1 and Figure 2 For the purpose of filtering the electrolyte, the structures of the first filter 300 and the second filter 400 in this embodiment are the same, and both include a filter cartridge 340 and a cartridge cover 350. The bottom of the filter cartridge 340 is fixed to the base 100, and the cartridge cover 350 is hermetically covered with the top of the filter cartridge 340 through a locking member 360. A filter element is provided in the filter cartridge 340. This filtering structure is a prior art and will not be elaborated here. At the same time, a gasket (not shown in the figure) is provided between the cartridge cover 350 and the filter cartridge 340. The gasket can achieve the seal between the cartridge cover 350 and the filter cartridge 340 to ensure that the electrolyte can circulate smoothly without flowing out of the filter cartridge. Of course, in order to ensure the hermetic closure between the cartridge cover 350 and the filter cartridge 340, several locking members 360 are provided and evenly spaced.

[0027] In order to lock the filter cartridge 340 and the cartridge cover 350, the locking member 360 includes a locking rod 361 and a locking handle 362. One end of the locking rod 361 is rotatably connected to the side wall of the filter cartridge 340. A locking groove 351 is formed in the side wall of the cartridge cover 350. The other end of the locking rod 361 can be inserted into the locking groove 351 and is threadedly connected to the locking handle 362. When the filter element needs to be replaced, the locking handle 362 can be rotated to loosen it from the cartridge cover 350, and then the locking rod 361 is rotated to disengage it from the locking groove 351 of the cartridge cover 350. At this time, the cartridge cover 350 can be opened to replace the internal filter element. After the replacement is completed, the cartridge cover 350 is covered on the filter cartridge 340, and the locking rod 361 is rotated to make the locking rod 361 snap into the locking groove 351. Finally, the locking handle 362 is rotated to press tightly on the cartridge cover 350 to achieve the hermetic closure between the cartridge cover 350 and the filter cartridge 340.

[0028] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry can smoothly implement the present utility model according to what is shown in the accompanying drawings of the specification and what is described above; however, any minor changes, modifications and equivalent variations made by those skilled in the relevant art without departing from the technical solution of the present utility model and by using the technical content disclosed above are equivalent embodiments of the present utility model; at the same time, any changes, modifications and equivalent variations made to the above embodiments based on the essential technology of the present utility model still fall within the scope of protection of the technical solution of the present utility model.
