The elastic part is arranged between the brush plate and the connecting block, and the elastic part is connected to the brush plate and the connecting block, and is used to push the brush plate to always abut against the circumferential outer wall of the material barrel. The guide rod is arranged in a one-to-one correspondence with the guide hole, one end of the guide rod is slidably inserted in the guide hole, and the other end is connected to the brush plate.

6. The pickling device according to claim 5, characterized in that: The anti-blocking component also includes a plurality of material guide plates, which are arranged along the axial direction of the material barrel and connected to the circumferential inner wall of the material barrel.

7. The pickling device according to claim 6, characterized in that: The spray assembly also includes a liquid storage tank, a spray pipe, a liquid return pipe and a pressure pump. The liquid storage tank is connected to the outer wall of the box body, one end of the spray pipe is connected to the interior of the liquid storage tank, and the other end is arranged along the axis of the material barrel and extended to be connected to the material barrel. The other end of the spray pipe is provided with a plurality of spray holes along its length direction. The number of the spray heads in the spray assembly is multiple, and the spray heads are arranged in a one-to-one correspondence with the spray holes and are connected to the spray holes. One end of the liquid return pipe is connected to the interior of the liquid storage tank, and the other end is connected to the interior of the box body. The pressure pump is arranged on the liquid return pipe.

8. The pickling device according to claim 7, characterized in that: The bracket includes a first support column, a second support column and a second linear drive unit that are spaced apart from each other. One end of the box is hinged to the first support column, and the other end abuts against the second support column. The fixed end of the second linear drive unit is hinged to the second support column, and the other end is hinged to the box, and is used to drive the box to rotate relative to the second support column around the axis of its hinge point.

9. A pickling system, characterized in that: The method comprises at least two pickling devices according to any one of claims 1 to 8.

10. A pickling method, characterized in that: Using the pickling system as claimed in claim 9 comprises the following steps: Loading, the extended end of the first linear drive unit drives the baffle plate to slide away from the material barrel, the opening of the material barrel is opened, the pickling material is put into the material barrel from the opening, and the opening is closed after the feeding is completed; In the first-stage pickling, the driving motor drives the material barrel to rotate relative to the box body, and the spray head opens to spray the inside of the material barrel. The material contacts the acid during the rotation process, completing the first-stage pickling; When unloading, the driving motor stops driving the material barrel to rotate relative to the box body, the spray head is closed, the extended end of the second linear drive unit drives the box body to rotate around the hinge point between it and the first support column, the extended end of the first linear drive unit drives the baffle plate to slide away from the material barrel, the opening of the material barrel opens, and the material is unloaded; Secondary pickling: the material that has completed the primary pickling is put into the next adjacent material barrel again. The driving motor drives the material barrel to rotate relative to the box again. The spray head is turned on again to spray the inside of the material barrel. The material contacts the acid again during the rotation process, completing the secondary pickling.
