[0021] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:

[0022] like Figures 1 to 3 As shown, an aluminum alloy dyeing pretreatment device includes a reaction tank 1, a material rack 2 and a raw material tank 3.

A boss is provided on one side of the tank cover 12 close to the tank body 11, a sealing strip is provided on the side of the boss, and a side groove 116 matching the boss is provided on the top surface of the tank body 11. The top surface of the tank body 11 is open in a large area, which is easy to cause the loss of the pretreatment agent in the tank body 11 due to the volatilization of the liquid. In turn, there are some requirements for the sealing of the tank cover 12. The cooperation between the boss and the side groove 116 makes the tank cover 12 and the tank body 11 tightly assembled, and the sealing strip can improve the sealing of the tank cover 12. A lifting cylinder 112 is provided on the side of the tank body 11, and the lifting cylinder 112 is fixedly connected to the tank body 11, and the telescopic end of the lifting cylinder 112 is fixedly connected to the tank cover 12.

A plurality of top blocks 221 are arranged in an array on the interlayer 22. The top blocks 221 lift the aluminum alloy, reduce the contact area between the aluminum alloy and the material rack 2, and make the surface of the aluminum alloy fully contact with the pretreatment agent.

[0025] The tank body 11 is connected to the raw material tank 3 through the intermediate pipe 4. The intermediate pipe 4 includes a main pipe 41 and multiple branch pipes 42. The main pipe 41 is provided with a feeding pump 44. One end of the main pipe 41 is connected to the tank body 11, and the other end is connected to the branch pipe 42. A plurality of mutually independent material chambers 33 are provided in the raw material tank 3, and a feeding port 32 is provided at the top of the raw material tank 3 corresponding to the material chamber 33.

In this way, the pretreatment agent is automatically configured.

[0026] The working principle of the specific implementation of the utility model is as follows: the aluminum alloy is placed on the material rack 2, and as the tank cover 12 is closed, the telescopic cylinder 121 retracts, and the material rack 2 carries the aluminum alloy and immerses it in the pretreatment agent in the tank body 11. The electronic acid-base tester 113 and the liquid level tester 114 monitor the pH value and liquid level changes of the liquid in the tank body 11 in real time, and control the feeding pump 44 to add the pretreatment agent into the tank body 11 through the first control circuit, so as to keep the physical and chemical indicators of the pretreatment agent in the tank body 11 within an appropriate range.
