Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1

[0018] refer to Figures 1-3A coating mixing device includes a mixing tank 1, a filter box 2 and a filter assembly 3. The top and bottom of the mixing tank 1 are respectively provided with a feed pipe 11 and a first discharge pipe 12. The first discharge pipe 12 is connected to the filter chamber 21 of the filter box 2. The filter box 2 is provided with a second discharge pipe. The filter box 2 is provided with an insertion port (not shown in the figure) for the filter assembly 3 to be inserted into the filter chamber 21 on one side.

[0019] At least two first bending portions 35 are symmetrically arranged on the side wall of the filter assembly 3. A horizontally extendable connecting assembly 4 is provided in the filter cavity 21, and the connecting assembly 4 corresponds one-to-one with the first bending portions 35. When the connecting assembly 4 retracts horizontally, it pulls the first bending portions 35 to fix the filter assembly 3 in the filter cavity 21.

[0020] It should be noted that valves (not shown in the figure) are installed on both the first discharge pipe 12 and the second discharge pipe 23. The opening and closing of the first discharge pipe 12 and the second discharge pipe 23 are controlled by the valves.

[0021] In this design, the worker first controls the connecting component 4 to extend, then inserts the filter component 3 into the filter chamber 21 through the socket. Once the filter component 3 is in the filter chamber 21, the worker controls the connecting component 4 to retract, pulling the first bend 35 on the side wall of the filter component 3 to fix the filter component 3 in the filter chamber 21. Then, the paint raw material can be added from the feed pipe 11, and the paint raw material in the mixing tank 1 can be stirred. After stirring is completed, the valves on the first discharge pipe 12 and the second discharge pipe 23 are opened. When it is necessary to replace the filter component 3, the worker controls the filter component 3 to extend, thereby loosening the filter component 3. Then, the worker can pull the filter component 3 out of the filter chamber 21. In this way, the filter component 3 is not easy to shake, and the replacement of the filter component 3 is convenient and quick.

[0022] In this embodiment, the connecting component 4 includes an elastic telescopic member 41 disposed on one side of the filter box 2 and a connecting block 42 disposed on the telescopic end of the elastic telescopic member 41. The filter box 2 has a through hole 22 corresponding to the elastic telescopic member 41 on one side. The telescopic end of the elastic telescopic member 41 passes through the through hole 22 and extends into the filter cavity 21. The connecting block 42 is provided with a second bending portion 43 corresponding to the first bending portion 35.

[0023] Specifically, when the worker needs to fix the filter assembly 3, the worker presses the elastic telescopic member 41 to extend the telescopic end of the elastic telescopic member 41, so as to drive the connecting block 42 and the second bending part 43 to move horizontally. Then, the worker inserts the filter assembly 3 into the filter cavity 21 from the socket and then releases his hand. Under the action of the elastic telescopic member 41, the telescopic end of the elastic telescopic member 41 drives the connecting block 42 and the second bending part 43 to reset, so that the second bending part 43 contracts and pulls the first bending part 35, thereby fixing the filter assembly 3.

[0024] Preferably, both the first bending portion 35 and the second bending portion 43 are hook-shaped. When the second bending portion 43 retracts, it hooks with the first bending portion 35 to fix the filter assembly 3. Providing the first bending portion 35 and the second bending portion 43 with hooks allows for better and more secure fixation of the filter assembly 3.

[0025] In this embodiment, the elastic telescopic member 41 includes a spring 412, a connecting plate 413 and a fixing plate 414 respectively connected to both ends of the spring 412, and a movable rod 411. The fixing plate 414 is connected to one side of the filter box 2. One end of the movable rod 411 moves sequentially through the connecting plate 413, the spring 412, the fixing plate 414 and the through hole 22, and extends into the filter cavity 21. The connecting block 42 is connected to the end of the movable rod 411 located in the filter cavity 21.

[0026] The other end of the movable rod 411 is threaded with a nut 415, which abuts against the connecting plate 413.

[0027] Specifically, first adjust the position of the nut 415 so that it abuts against the connecting plate 413, compressing the spring 412. Before inserting the filter assembly 3 into the filter chamber 21, push the movable rod 411 horizontally to move the second bend 43 on the connecting block 42 and compress the spring 412 through the nut 415. Then, after the worker inserts the filter assembly 3 into the filter chamber 21 through the insertion port, release the hand that was pushing the movable rod. Under the action of the spring 412, the second bend 43 is driven to contract and pull the first bend 35, thereby fixing the filter assembly 3 in the filter chamber 21.

[0028] More preferably, the fixing plate 414 is connected to one side of the filter box 2 by bolts. The bolt connection method facilitates the replacement of the spring 412.

[0029] Preferably, the mixing tank 1 includes a tank body 15 and a motor 13. The feed pipe 11 and the first discharge pipe 12 are respectively disposed at the top and bottom of the tank body 15. A stirring rod 14 is provided on the rotating shaft of the motor 13. The stirring rod 14 is driven by the motor 13 to rotate, thereby stirring the paint raw materials in the tank body 15.

[0030] Preferably, a support plate 6 is horizontally arranged on the side of the filter box 2, and a hydraulic pump 5 is provided on the support plate 6. The hydraulic pump 5 is provided with an inlet pipe 51 and an outlet pipe 52. The inlet pipe 51 is connected to the filter chamber 21, and the outlet pipe 52 is connected to the stirring chamber 151 of the tank body 15.

[0031] Specifically, the valves of the first discharge pipe 12 and the second discharge pipe 23 are closed. After the coating is stirred, the valve of the first discharge pipe 12 is opened to allow the stirred coating to flow into the filter chamber 21. Then the valve of the first discharge pipe 12 is closed. After that, the hydraulic pump 5 is turned on to extract the coating from the filter chamber 21. The coating flows back into the stirring chamber 151 of the tank 15 after passing through the inlet pipe 51 and the outlet pipe 52 to continue stirring. After stirring is completed again, the valve of the first discharge pipe 12 is opened to allow the coating to flow through the filter assembly 3 for filtration again. When discharging, the valve of the second discharge pipe 23 can be opened. In this way, the coating can be stirred and filtered multiple times, which improves the mixing effect and reduces impurities when the coating is used.

[0032] More preferably, there are two first bending portions 35. Two first bending portions 35 are provided, which hook together with two second bending portions 43 to fix the filter assembly 3.

[0033] In this embodiment, the filter assembly 3 includes a mounting plate 31. A filter plate 32 is provided on one side of the mounting plate 31, and a handle 33 is provided on the other side. When the filter plate 32 is inserted into the filter chamber 21 through the insertion port, the mounting plate 31 can seal the insertion port. The first bent portion 35 is symmetrically arranged on the side wall of the filter plate 32. The handle 33 on the mounting plate 31 allows workers to easily pull out or insert the filter plate 32 into the filter chamber 21, thereby filtering impurities in the paint through the filter plate 32.

[0034] Preferably, the mounting plate 31 is further provided with a sealing strip 34 that matches the socket, the sealing strip 34 being disposed on the side of the mounting plate 31 facing away from the handle 33. The sealing strip 34 is used to improve the sealing effect.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of the present utility model, and these improvements or modifications should also be considered within the protection scope of the present utility model.
