The utility model recovers and filters the pickling liquid in the box through the recovery component and the filter element on the fixed box, thereby reducing the impurity content in the pickling liquid and ensuring the pickling effect of the suspension system.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model to solve its technical problem is: a copper strip pickling line filtering device, including a box body of the pickling line, a fixed box is provided on the box body, a filter element for filtering the pickling liquid is provided on the fixed box, and a recovery component for recovering the pickling liquid is provided outside the box body.

[0006] As a further solution of the utility model, the recovery component includes a recovery box arranged outside the box body, a delivery pump is provided in the recovery box, a connecting pipe is provided at the liquid outlet end of the delivery pump, one end of the connecting pipe extends to the upper side of the filter element, and a recovery pipe is provided on the recovery box.

[0007] As a further solution of the utility model, a valve is provided on the connecting pipe.

[0008] As a further solution of the utility model, an observation tube is provided on the recovery box.

[0009] As a further solution of the utility model, a sealing cover is provided on the observation tube, and the sealing cover is connected to the observation tube by bolts.

[0010] As a further solution of the utility model, the fixed box is provided with flow holes.

[0011] As a further solution of the utility model, a connecting rod is provided on the fixed box, and the connecting rod is connected to the box body.

[0012] As a further solution of the utility model, the connecting rod is welded to the box body.

[0013] As a further solution of the utility model, a clamping block is provided on the connecting rod, and the clamping block is clamped with the side wall of the box body.

[0014] The beneficial effects of the utility model are:

[0015] The recovery component recovers the pickling liquid on the pickling line to a fixed box, and filters the pickling liquid through the filter element to reduce impurities in the pickling liquid. The filtered pickling liquid falls into the box to continue pickling, thereby increasing the pickling effect of the pickling line and making it more practical.

[0016] The stable recovery of the pickling liquid is achieved through the cooperation of the recovery box, the delivery pump, the connecting pipe and the recovery pipe, thereby ensuring that the pickling liquid after pickling on the pickling line is stably recovered to the fixed box for filtration.
