[0044] A ventilation groove 51 is opened on the upper part of the box body 1 and extends through the outer surface of the box body 1 to the inner cavity of the box body 1.

[0046] Example 4

[0047] like Figure 8 As shown, based on Example 3, the utility model provides a technical solution: preferably, the second filtering structure 66 includes a partition 661, the lower end of the partition 661 is fixedly connected to the upper end of the liquid storage tank 61, a slide groove 662 is opened on one side of the partition 661, and the inner cavity of the slide groove 662 is slidably connected to a dust box 663.

[0048] In this embodiment, by operating the conveying pipe 65, the rust removal liquid in the inner cavity of the immersion box 64 flows into the inner cavity of the second dust box 663 together with the rust chips. The rust chips in the rust removal liquid can be filtered through the filter screen on the bottom wall of the inner cavity of the second dust box 663. The filtered rust removal liquid will flow into the inner cavity of the liquid storage tank 61, waiting to be used on the lower side. When the rust chips in the inner cavity of the second dust box 663 accumulate to a certain extent, the second dust box 663 is operated to slide and pull it out from the inner cavity of the slide groove 1 662, and then the rust chips accumulated in the inner cavity of the second dust box 663 are processed.

[0049] The working principle of the rust removal device for scrap metal recycling will be described in detail below.

[0050] like Figure 1-8As shown, when it is necessary to remove rust from scrap metal, firstly, the scrap metal to be removed rust is placed in the inner cavity of the mesh box 31, and then the electric telescopic rods 32 are operated to drive the electric telescopic rods 32 to push the mesh box 31 toward the soaking box 64. When the electric telescopic rods 32 push the mesh box 31 down to a suitable position, the water pump 62 is operated to transport the rust removal liquid in the inner cavity of the liquid storage tank 61 to the inner cavity of the soaking box 64 through the infusion tube 63, and then the rust removal liquid will soak and remove rust from the scrap metal in the inner cavity of the mesh box 31 through the upper flow hole of the mesh box 31.

[0051] Then, by operating the hydraulic cylinder 41, the output end of the piston rod of the hydraulic cylinder 41 pushes the waterproof cover 42 to move toward the net box 31. At the same time, the waterproof cover 42 drives the motor 1 43 and the friction ball 44 to move together. When the friction ball 44 contacts the scrap metal in the inner cavity of the net box 31, the motor 1 43 drives the friction ball 44 to rotate, thereby driving the friction ball 44 to rub and clean the scrap metal, accelerating the rust removal process of the scrap metal. When the rust removal of the scrap metal in the inner cavity of the net box 31 is completed;

[0052] Stop the motor 43, and then use the hydraulic cylinder 41 to drive the waterproof cover 42 to reset, thereby pulling the motor 43 and the friction ball 44 to reset, and then use the electric telescopic rod 32 to pull the net box 31 up. When the net box 31 rises to a certain position, operate the motor fan 52 to allow the motor fan 52 to send strong wind to the net box 31, so that the wind can be used to dry the water marks on the scrap metal in the inner cavity of the net box 31, and at the same time, some waste chips remaining in the inner cavity of the net box 31 will be blown toward the dust box 53, and then the waste chips will be collected by the dust box 53;

[0053] Then, by operating the conveying pipe 65, the rust removal liquid in the inner cavity of the immersion box 64 can flow into the inner cavity of the second dust box 663 together with the rust chips. The rust chips in the rust removal liquid can be filtered through the filter screen on the bottom wall of the inner cavity of the second dust box 663. The filtered rust removal liquid will flow into the inner cavity of the liquid storage tank 61, waiting to be used on the lower side. When the rust chips in the inner cavity of the second dust box 663 accumulate to a certain extent, the second dust box 663 can be slid and pulled out from the inner cavity of the slide groove 1 662 by operating the second dust box 663, and then the rust chips accumulated in the inner cavity of the second dust box 663 can be processed, and then the air-dried scrap metal can be taken out from the inner cavity of the mesh box 31, and then new scrap metal to be processed can be put into the inner cavity of the mesh box 31, and then the above steps are repeated to remove the rust from the scrap metal.

[0054] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
