[0008] A filter structure is installed on the outer wall of one end of the spray structure.

[0009] When using this device, the spray structure facilitates cleaning, thereby improving the applicability of the pre-coating treatment tank for low-pressure aluminum alloy wheels; the filter structure facilitates filtration, further enhancing the ease of use of the pre-coating treatment tank for low-pressure aluminum alloy wheels.

[0010] Preferably, the spray pipes are symmetrically distributed on both sides inside the second treatment tank.

[0011] Preferably, the spray pipes are evenly spaced on one side of the diversion pipe. Filtered water enters the interior of the diversion pipe and then the interior of the spray pipes, ensuring a cleaning effect through the action of the spray pipes.

[0012] Preferably, one end of the diversion pipe extends to the outside of the housing. Finally, the water is discharged through the first and second nozzles. The action of the first and second nozzles ensures that the filtered water is evenly distributed on the wheel hub surface, further improving cleaning efficiency.

[0013] Preferably, the filtration structure includes a cylinder, a filter cartridge, a cover plate, a water inlet pipe, a fixing frame, and a connecting frame. The cylinder is fixed to the outer wall of one end of the spray structure box. A cover plate is fixed to the top of the cylinder. A water inlet pipe passes through the inside of the cover plate. A connecting frame is fixed to the bottom of the cover plate. A fixing frame is provided inside the connecting frame. The bottom of the fixing frame extends to the outside of the connecting frame and is fixed with the filter cartridge.

[0014] Preferably, one side of the bottom of the cylinder is fixedly connected to one end of the diversion pipe, and one end of the water inlet pipe is fixed with a flange. The flange facilitates connection to an external water pump, and the filter cartridge filters impurities from the water, ensuring water clarity and preventing clogging of the first and second nozzles, while impurities remain inside the filter cartridge.

[0015] Preferably, the inner wall of the connecting frame is provided with internal threads, and the outer wall of the fixing frame is provided with external threads. The fixing frame and the connecting frame are connected by threaded engagement. Under the cooperation of the external and internal threads, the fixing frame and the connecting frame are fixed or separated, so as to fix or disassemble the filter cartridge and thus clean the impurities inside the filter cartridge.

[0016] The present invention provides a pretreatment groove for low-pressure aluminum alloy wheel hubs before painting, the advantages of which are:

[0017] By incorporating a spray structure, filtered water enters the interior of the diversion pipe and then the interior of the spray pipe. Under the action of the spray pipe, the cleaning effect is ensured, and finally, the water is discharged through the first and second spray nozzles. The action of the first and second spray nozzles ensures that the filtered water is evenly distributed on the surface of the wheel hub, further improving the cleaning efficiency and realizing the easy-to-clean function of the device. This enhances the applicability of the pre-coating treatment tank for low-pressure aluminum alloy wheel hubs during use.

[0018] With its filtration structure and flange, the device facilitates the connection of an external water pump. The filter cartridge effectively removes impurities from the water, ensuring its clarity and preventing clogging of the first and second nozzles. Impurities remain inside the filter cartridge. The interlocking external and internal threads allow the fixing frame and connecting frame to be fixed or separated, enabling the filter cartridge to be secured or disassembled and its interior cleaned. This design facilitates filtration and enhances the usability of the pre-coating treatment tank for low-pressure aluminum alloy wheels. Attached Figure Description
