[0070] The working principle of the present invention is: when the waste liquid used in the coating machine equipment needs to be processed, the motor 102 of the active component in the driving mechanism 10 is started first. The output end of the motor 102 drives the gear 103 to run counterclockwise, and at this time the gear 103 and the rack 105 meshing with the gear 103 mesh with each other. After meshing with the gear 103, the rack 105 moves to the right with the cooperation of the fixed frame 1010 and the carrier block, stretching the extrusion spring. When the rack 105 moves to the right to the maximum mileage, the rack 105 is disengaged from the gear 103, but due to the setting of the extrusion spring, after the rack 105 moves to the right to the maximum mileage, it is disengaged from the gear 103 during the counterclockwise rotation of the gear 103. The rack 105 is always at the maximum mileage of the right shift in a dynamic state.

[0071] During the rightward movement of the rack 105, the movement of its carrier block will drive the moving plate 108 to move synchronously through the splicing rod 109, and the moving plate 108 will cause the adjustment plate 1011 loaded thereon to move and adjust. During the rightward movement and adjustment of the adjustment plate 1011, the convex rod slidably connected to the upper inclined groove thereof drives the horizontal plate 82 in the transmission assembly 8 to move downward and adjust under the action of the movement of the adjustment plate 1011. At this time, the downward adjustment of the horizontal plate 82 synchronously drives the movable rod 81 and the back plate 83 to move.

[0072] The downward movement of the movable rod 81 causes the conical platform 54 at its bottom to move downward synchronously inside the separation barrel 51. When the rack 105 moves right to the maximum distance, the conical platform 54 moves to the maximum distance driven by the movable rod 81, and the conical platform 54 blocks the position below the preliminary separation net 52 in the separation barrel 51.

[0073] When the back plate 83 moves downward, the round rod movably slidably mounted on the slide rail 96 of the airflow cleaning assembly 9 in the airflow cleaning mechanism is adjusted along the inclined groove on the back plate 83. This causes the U-shaped tube 95 in the airflow cleaning assembly 9 to move upward. The U-shaped tube 95 causes the annular housing 91 to move upward through the air inlet pipe 94, thereby driving the blocking ring 93 to move upward synchronously through the drainage pipe 92.

[0074] When the rack 105 moves right to the maximum mileage, the transmission assembly 8 is adjusted to the maximum extent, and then the airflow cleaning assembly 9 completes the adjustment of the maximum mileage. At this time, the annular shell 91 corresponds to the air inlet notch opened on the upper tube 53 in the preliminary treatment mechanism 5, and the barrier ring 93 moves to the top of the preliminary separation net 52, so as to prevent the waste liquid from being thrown into the internal space of the separation barrel 51 above the barrier ring 93 during centrifugal treatment.

[0075] The gear 103 drives the gear ring 104 to move so that the preliminary processing mechanism 5 performs an integral rotation movement.

[0076] The air pump body 16 in the airflow cleaning mechanism is opened, and the air is delivered to the U-shaped tube 95 in the airflow cleaning assembly 9 through the hose. The gas entering the U-shaped tube 95 enters the annular shell 91 from the air inlet pipe 94. At this time, the inner space of the annular shell 91 is connected with the inner space of the sandwich shell 55 through the air inlet notch, and then part of the gas enters the inner space of the sandwich shell 55 through the air inlet notch, and then is discharged into the separation barrel 51 through the air holes on the sandwich shell 55. The other part of the gas enters each drainage tube 92 and is then discharged from the gas nozzles opened thereon.

[0077] After completing the above operations, the waste liquid in the cleaning tank is transported by the input pipeline from the feed pipe on the rotating connector 7 into the separation barrel 51 in the preliminary treatment mechanism 5. At this time, the preliminary treatment mechanism 5 is in a rotating state, and the waste liquid entering the separation barrel 51 flows around by itself after falling on the conical table 54. The centrifugal force generated by the rotation of the preliminary treatment mechanism 5 not only accelerates the diffusion speed of the waste liquid to the surroundings, but also enables the waste liquid to pass through the preliminary separation net 52 under the centrifugal action to achieve preliminary separation and treatment with impurities. When the preliminary treatment mechanism 5 realizes the preliminary treatment of the waste liquid under the action of the rotating centrifugal force, the gas entering the separation barrel 51 can only be discharged from the preliminary separation net 52 due to the blocking effect of the conical table 54, thereby further carrying the waste liquid to increase its processing speed on the preliminary separation net 52.

[0078] The waste liquid after the preliminary treatment converges in the barrel body 11 of the preliminary treatment barrel 1 under the action of gravity, and then falls on the fine separation net 23 in the fine treatment mechanism 2. As the preliminary treatment mechanism 5 rotates, it simultaneously drives the scraping member 6 loaded thereon to move, thereby scraping the waste liquid falling on the fine separation net 23, thereby accelerating the separation and treatment efficiency of the waste liquid on the fine separation net 23 under the action of gravity.

[0079] The waste liquid treated by the fine separation net 23 meets the standard for reuse, and then the delivery pump body 15 pumps the filtered waste liquid back to the cleaning tank through the cooperation of the conduit and the discharge pipe for reuse.

[0080] When the preliminary separation net 52 in the preliminary treatment mechanism 5 needs to be cleaned after the waste liquid is treated, the motor 102 is started to move clockwise, and then under the action of the extrusion spring, the rack 105 and the gear 103 are quickly meshed, and the gear 103 and the gear ring 104 are also meshed.

[0081] The gear ring 104 rotates in the opposite direction, and the rack 105 moves leftward under the rotation of the gear 103. When the rack 105 moves leftward, it drives the carrier block to move under the action of the fixed frame 1010, and then the splicing rod 109 drives the moving plate 108 to move leftward, so that the adjustment plate 1011 moves synchronously.

[0082] When the rack 105 moves to the left to the maximum mileage, the gear ring 104 continues to move. At this time, the state of the rack 105 is similar to that when it was at the maximum mileage on the right side, and the transmission assembly 8 is reset.

[0083] After the transmission assembly 8 is reset, the conical platform 54 moves up to achieve the blocking effect, and then the airflow cleaning assembly 9 in the airflow cleaning mechanism moves down for adjustment. After the airflow cleaning assembly 9 moves down, the annular shell 91 is misaligned with the air inlet notch. At this time, all the gas entering the annular shell 91 is diverted and discharged by each drainage pipe 92.

[0084] When the airflow cleaning assembly 9 moves down to the maximum distance, the drainage pipe 92 sprays air from the outside to the inside to the preliminary separation net 52 on the separation barrel 51. In this way, the impurities adhering to the inner wall of the preliminary separation net 52 are separated from the preliminary separation net 52 under the action of the gas, and pass through the collection cylinder 24 under the influence of gravity and gas to enter the collection box 3 for collection, thereby reducing the burden of manual cleaning.

[0085] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
