Referring to fig. 1 of the drawings, fig. 1 is a schematic structural diagram of an on-line treatment device for wire acid-washing phosphated slag provided by the utility model, and as shown in fig. 1, the on-line treatment device for wire acid-washing phosphated slag provided by the utility model comprises a phosphatization tank 1 and two filter tanks 2; a liquid outlet of the phosphating tank 1 is connected to a first pipeline 31 of a three-way pipe, and a second pipeline 32 and a third pipeline 33 of the three-way pipe are respectively connected to the two filtering tanks 2; the filter tank is used for filtering the phosphating solution to deposit the phosphating slag in the phosphating solution. The two filtering ponds 2 are both connected with a clear liquid pond 4, and the clear liquid pond 4 is used for filling the phosphating liquid filtered by the filtering ponds. The clear liquid tank 4 is connected with the liquid inlet end of the phosphating tank 1; the second pipeline 32 and the third pipeline 33 are both provided with pipeline switches. The pipeline switch is used for controlling the opening or closing of the corresponding pipeline.

The pipe switch of the tee controls the second pipe 32 and the third pipe 33 so that one of the second pipe 32 and the third pipe 33 is in a conducting state and the other is in a closed state. Therefore, the phosphating solution in the phosphating tank 1 can be discharged into a filtering tank in time for filtering, so that the phosphating slag is deposited into the filtering tank for treatment. And at the moment, the other filtering tank is not conducted, so that the phosphorization slag deposited in the filtering tank can be treated. The two filter tanks 2 alternately filter the phosphating solution, so that the phosphating slag can be cleaned without stopping the phosphating and pickling production line, and the production efficiency of the phosphating and pickling production line is improved.

In a possible implementation, the two filter tanks 2 are each connected to a slag press 5. And the slag press machine 5 is used for pressing slag of the sediment in the filtering tank.

After phosphorization liquid in clear liquid pond 4 is heated through heating device 6, carry the feed liquor end in bonderizing pond 1, carry out pickling bonderizing to the wire rod in the bonderizing pond 1.

In a possible implementation manner, the clear liquid tank 4 is connected with the liquid inlet end of the phosphating tank 1 through a liquid guide pipe, and a liquid guide switch is arranged on the liquid guide pipe. Because the two liquid guide pipes are communicated to the liquid inlet end of the phosphating tank 1, in order to reduce the possibility that phosphating liquid flows into the liquid guide pipe of the other liquid cleaning tank 4 from the liquid guide pipe of one liquid cleaning tank 4, the liquid guide switch is arranged and used for closing the other liquid guide pipe when one liquid guide pipe is conducted.

In a possible implementation manner, a connection port of the filtering tank for connecting the clear liquid tank 4 is arranged on the upper half side of the filtering tank. This arrangement reduces the possibility of sucking the sediment in the filtration tank into the clear liquid tank 4.

The working principle of the wire acid pickling phosphorization slag on-line treatment device provided by the utility model is as follows: initially, one of the pipe switches is opened, e.g., the pipe switch on the second pipe 32 is opened, while the pipe switch on the third pipe 33 is closed. Then the phosphating solution containing the phosphating slag in the phosphating tank 1 is input into a filtering tank connected with a second pipeline 32 through the second pipeline 32, the phosphating solution containing the phosphating slag is filtered in the filtering tank, the phosphating slag is precipitated, the clear liquid on the upper layer is conveyed into a clear liquid tank 4, and the clear liquid is heated by a heating device 6 and then is guided into the phosphating tank 1 through a liquid guide pipe to complete circulation.

After a certain time of recirculation, the pipeline switch on the second pipeline 32 is closed, and the pipeline switch on the third pipeline 33 is opened at the same time, and the work is repeated by the filter tank, the clear liquid tank 4, the heating device 6 and the liquid guide pipe on the side of the third pipeline 33. At this time, the filter tank connected to the second pipe 32 performs slag pressing processing on the sediment inside by the slag pressing machine 5.
