Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0022] This utility model provides, for example Figure 1-5 The cleaning device shown is for spray guns of an acid regeneration unit. It includes a holding platform 1, a cleaning tank 2 installed on the upper end of the holding platform 1, and a rinsing mechanism installed on the holding platform 1. The rinsing mechanism includes a holding rack 3 installed in the cleaning tank 2. The disassembled spray gun parts are placed on the holding rack 3. Multiple liquid inlet pipes 4 are installed on one side of the cleaning tank 2. The inlet end of the spray gun parts is connected to the liquid inlet pipe 4. A cleaner 5 is installed on the holding platform 1. The cleaner 5 can introduce the soaking solution into the interior of the spray gun parts through the liquid inlet pipe 4.
[0023] The process of cleaning the spray gun using this device is as follows: After disassembling the spray gun and draining the residual acid inside, multiple spray gun parts are installed on the holding rack 3, and the inlet end of the spray gun parts is connected to the liquid inlet pipe 4. The soaking solution is introduced into the spray gun parts through the cleaner 5, allowing the soaking solution to move inside the spray gun parts and finally flow out into the cleaning tank 2. When the liquid level of the soaking solution exceeds the spray gun parts, the cleaner 5 is turned off. At this time, the inside and outside of the spray gun parts can be soaked, and there is no air inside the spray gun parts, which allows for a more thorough soaking. After a period of time, the soaking solution is moved into the spray gun parts again through the cleaner 5 to replace the soaking solution inside the spray gun parts and to remove the sediment inside the spray gun parts. After replacing with a new soaking solution, the sediment inside the spray gun parts can be dissolved again, resulting in a better cleaning effect.
[0024] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 4 Included with instruction manual Figure 5 The rack 3 includes multiple support plates 6 installed at the lower end of the cleaning tank 2. Multiple limiting grooves 7 are opened at the upper end of the support plates 6. The spray gun accessories are placed in the limiting grooves 7 and fixed with bolts. Placing the spray gun accessories in the limiting grooves 7 can facilitate limiting the spray gun accessories. Then, the accessories are installed on the support plates 6 by bolt connection, which can prevent the spray gun accessories from being blown open when liquid is introduced into the spray gun accessories.
[0025] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 4 Included with instruction manual Figure 5 The cleaner 5 includes a solution tank 8 installed on one side of the upper end of the holding platform 1. A first movable piston 9 is installed inside the solution tank 8. A drive frame 10 is installed on one side of the first movable piston 9. The drive frame 10 can drive the first movable piston 9 to move inside the solution tank 8. The inlet pipe 4 can connect the solution tank 8 and the cleaning tank 2.
[0026] The process by which the cleaner 5 introduces the soaking solution into the spray gun accessories is as follows: Under normal conditions, an appropriate amount of soaking solution is put into the solution tank 8, and the first moving piston 9 is moved towards the cleaning tank 2 by the drive frame 10, so that the solution in the solution tank 8 can be discharged into the spray gun accessories through the liquid inlet pipe 4.
[0027] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 3The lower surface of the solution tank 8 is lower than the lower surface of the cleaning tank 2. A connecting pipe 11 is installed at the lower end of the cleaning tank 2, with one end of the connecting pipe 11 extending into the solution tank 8. A connecting rod 12 is installed on the front side of the first moving piston 9, and a second moving piston 13 is installed at one end of the connecting pipe 11. The second moving piston 13 can extend into the connecting pipe 11. When the first moving piston 9 moves towards the cleaning tank 2, the second moving piston 13 can first enter the connecting pipe 11, thereby preventing the solution in the cleaning tank 2 from returning to the solution tank 8. The solution is then sprayed out through the spray gun accessories and accumulates in the cleaning tank 2, allowing the outer surface of the spray gun accessories to be soaked. After soaking, the first moving piston 9 returns to its original position, and the second moving piston 13 is removed from the connecting pipe 11. Then, the solution in the cleaning tank 2 can return to the solution tank 8 through the connecting pipe 11.
[0028] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 4 Included with instruction manual Figure 5 The solution tank 8 is equipped with an exhaust pipe 14 at the top. The first moving piston 9 can be positioned at one end to both sides of the exhaust pipe 14. When the first moving piston 9 is located on the side of the exhaust pipe 14 away from the cleaning tank 2, the second moving piston 13 is located outside the connecting pipe 11. When the second moving piston 13 enters the connecting pipe 11, the first moving piston 9 moves to the other side of the exhaust pipe 14, which allows the solution level in the solution tank 8 to rise slowly. Air can be discharged through the inlet pipe 4 and the spray gun accessories, and residual acid in the spray gun accessories can also be discharged. Then the solution can gradually soak the spray gun accessories. When the first moving piston 9 moves in the opposite direction, the liquid level in the cleaning tank 2 that is higher than the spray gun accessories can be extracted first, and then the air in the cleaning tank 2 can be extracted. When the first moving piston 9 moves to the side of the exhaust pipe 14 away from the cleaning tank 2, the second moving piston 13 is removed from the connecting pipe 11, which allows the solution in the cleaning tank 2 to return to the solution tank 8.
[0029] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 4 Included with instruction manual Figure 5 The drive frame 10 includes a movable screw 15 mounted on one side surface of the first movable piston 9, a rolling bearing 16 mounted on one side surface of the solution tank 8, a screw sleeve 17 mounted inside the rolling bearing 16, the screw sleeve 17 and the movable screw 15 being connected by threads, a first gear 18 mounted on the outside of the screw sleeve 17, a servo motor 19 mounted on the container 1, a second gear 20 mounted on the rotating end of the servo motor 19, and the first gear 18 and the second gear 20 meshing.
[0030] The process of the drive frame 10 driving the first moving piston 9 to move is as follows: the servo motor 19 is started to rotate, the servo motor 19 can drive the second gear 20 to rotate, the second gear 20 meshes with the first gear 18, which can drive the first gear 18 and the screw sleeve 17 to rotate, the screw sleeve 17 and the moving screw 15 are connected by threads, which can drive the moving screw 15 and the first moving piston 9 to move.
[0031] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 4 Included with instruction manual Figure 5 The cleaning box 2 is equipped with a filter box 21, which is located below the outlet end of the spray gun accessories. The filter box 21 has multiple filter ports 22 at its lower end. The filter box 21 is installed in the lower end of the cleaning box 2 by multiple fixing rods 23. The filter box 21 can collect the impurities and liquid sprayed from the spray gun accessories. The filter ports 22 can facilitate the passage of liquid and intercept impurities.
