[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model provides a technical solution: a hot dip plating tank with filtering effect, comprising an operating table 1, a tank body 10 is provided on the upper end surface of the operating table 1, a circulation pump 11 is fixedly installed in the hot dip plating tank, a first circulation pipe 14 and a second circulation pipe 13 are fixedly connected at both ends of the circulation pump 11, a cavity 2 is provided in the middle of the first circulation pipe 14, a filter 21 is inserted and installed in the cavity 2, sealing sleeves 22 are provided at the upper and lower ends of the outer periphery of the filter 21, the upper and lower sealing sleeves 22 are respectively sleeved with the outer peripheries of the first circulation pipe 14 on both sides, and a first threaded sleeve 23 threadably matched with the two sealing sleeves 22 is rotatably installed on the outer periphery of the filter 21.

[0024] Working principle: When filtering impurities in the plating solution, the circulation pump 11 is started, and the first circulation pipe 14 and the second circulation pipe 13 are cooperated to circulate the plating solution inside the tank body 10, and when the plating solution flows through the filter 21, the impurities in the plating solution can be filtered through the filter 21;

[0025] Then, the first threaded sleeve 23 is rotated on the periphery of the filter 21. Through the threaded cooperation between it and the upper and lower sealing sleeves 22, the two sealing sleeves 22 can be driven to move toward each other, so that the sealing sleeves 22 are separated from the first circulation pipe 14, so that the filter 21 can be disassembled at the cavity 2, so that the impurities inside the filter 21 can be collected.

[0026] Specifically, a discharge pipe 15 is fixedly installed at the outer end of the first circulation pipe 14 , an installation cavity 12 is opened on the outer side of the operating table 1 , and the filter 21 and the discharge pipe 15 are arranged in the installation cavity 12 .

[0027] A discharge pipe 15 is provided. After the immersion plating operation, the valve at the discharge pipe 15 is opened to discharge the immersion plating liquid outward. The installation cavity 12 is provided to facilitate the operation of the discharge pipe 15 and the filter 21 outside the device.

[0028] It is worth mentioning that the upper and lower ends of the filter 21 are respectively fixedly installed with limit rings 24 that fit with the facing end surfaces of the first circulation pipes 14 on both sides, the first threaded sleeve 23 is rotatably installed between the two limit rings 24, and the outer periphery of the first circulation pipes 14 on the upper and lower sides is fixedly installed with limit clamps 241 that match the two sealing sleeves 22, and the outer sides of the facing end surfaces of the first circulation pipes 14 on the upper and lower sides are provided with positioning slots 25, and the outer sides of the limit rings 24 on both sides are fixedly installed with positioning blocks 251 that are plugged into the positioning slots 25, and the inner wall surfaces of the sealing sleeves 22 on the upper and lower sides are provided with first limit slide grooves 26, and the outer periphery of the limit rings 24 on both sides is fixedly installed with first limit sliders 261 that slidably cooperate with the first limit slide grooves 26.

[0029] When installing the filter 21, the filter 21 is placed in the cavity 2, and the positioning block 251 and the positioning slot 25 are plugged into each other, and then the first threaded sleeve 23 is rotated on the periphery of the filter 21. Due to the plug-in cooperation between the positioning block 251 and the positioning slot 25, the rotating first threaded sleeve 23 is prevented from rotating, and the filter 21 is driven to rotate with it. Then, through the sliding cooperation between the first limiting slider 261 and the first limiting groove 26, the movement direction of the sealing sleeve 22 is restricted. The rotating first threaded sleeve 23 can drive the two sealing sleeves 22 to move in reverse through the thread cooperation between it and the two sealing sleeves 22, so that the two sealing sleeves 22 are respectively plugged into the first circulation pipes 14 on both sides, thereby achieving the effect of installing the filter 21. Conversely, the filter 21 can be disassembled by rotating the first threaded sleeve 23 in the opposite direction.

[0030] It is worth noting that a filter net 3 is slidably installed in the filter 21, and a movable snap ring 32 and a fixed snap ring 31 are slidably and fixedly installed on the upper and lower sides of the inner cavity of the filter 21 respectively. The movable snap ring 32 and the fixed snap ring 31 are respectively arranged on the upper and lower sides of the filter net 3, and a second limiting groove 35 is opened on the inner wall of the filter 21. A second limiting slider 34 that slidably cooperates with the second limiting groove 35 is fixedly installed on the periphery of the filter 21 and the movable snap ring 32, and a second threaded sleeve 33 that cooperates with the thread of the inner wall of the filter 21 is rotatably installed on the upper end surface of the movable snap ring 32.

[0031] A filter screen 3 is arranged in the filter 21, and the filter screen 3 is used to give the filter 21 the ability to filter impurities. When the filter screen 3 is installed, the filter screen 3 and the movable snap ring 32 are slidably installed into the inner cavity of the filter 21 through the sliding cooperation between the second limiting slider 34 and the second limiting slide groove 35. When the second threaded sleeve 33 contacts the inner wall surface of the filter 21, the second threaded sleeve 33 is rotated, and the movable snap ring 32 is driven to move downward through the thread cooperation between the second threaded sleeve 33 and the inner wall of the filter 21. In cooperation with the fixed snap ring 31, the filter screen 3 can be positioned in the filter 21, so that the filter screen 3 can be prevented from loosening during the flow of the immersion solution.

[0032] Among them, structures such as the filter screen 3 and the circulation pump 11 are all made of high temperature resistant materials.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
