[0022] As Figures 1-3 shown, a copper-containing waste liquid purification and recovery device includes a reaction barrel 1 and a waste liquid tank 2. Support columns 3 are arranged around the waste liquid tank 2, and the reaction barrel 1 is arranged on the support columns 3. A liquid inlet pipe 4 is arranged on the side wall of the reaction barrel 1 near the top, and the liquid inlet pipe 4 is communicated with the inner cavity of the reaction barrel 1. A liquid outlet pipe 5 is arranged at the bottom of the reaction barrel 1, and the liquid outlet pipe 5 is communicated with the inner cavity of the reaction barrel 1. The liquid outlet pipe 5 is located directly above the waste liquid tank 2. A drain pipe 6 is arranged at the bottom of the waste liquid tank 2, and the drain pipe 6 is communicated with the inner cavity of the waste liquid tank 2. A filter element 7 is arranged in the waste liquid tank 2. Wings 8 extending outward are arranged on both sides of the top of the filter element 7, and a hydraulic cylinder 9 is arranged below the wings 8. The output shaft of the hydraulic cylinder 9 is connected to the wings 8.

[0023] In this embodiment, the reaction barrel 1 serves as the reaction place for the copper-containing waste liquid. Iron powder can be added therein to displace copper powder. After displacement, the copper powder will be discharged into the waste liquid tank 2 through the liquid outlet pipe 5 along with the copper-containing waste liquid. The copper powder will stay on the filter element 7, and the filter element 7 will rise under the action of the hydraulic cylinder 9, thus facilitating the staff to recover the copper powder.

[0024] In this embodiment, the hydraulic cylinder 9 can be replaced by a pneumatic cylinder and an electric push rod.

[0025] Further, the filter element 7 includes an outer frame 10 and an inner filter screen 11, and the inner filter screen 11 is arranged at the bottom of the outer frame 10. A notch is arranged on one side of the outer frame 10, and a baffle 12 is arranged on the notch. The baffle 12 is detachably connected to the notch.

[0026] In this embodiment, jacks are provided on the outer frame 10 and the baffle 12. A bolt can be inserted into the jacks, and the baffle 12 can be fixed in the notch by the bolt. When the bolt is pulled out, the baffle 12 can be withdrawn, facilitating the collection of copper powder.

[0027] Furthermore, an openable cover 13 is provided at the top of the reaction barrel 1. A driving motor 14 is provided on the cover 13, and a stirring paddle 15 is provided on the output shaft of the driving motor 14. The stirring paddle 15 is located in the reaction barrel 1.

[0028] In this embodiment, the driving motor 14 operates to drive the stirring paddle 15 to rotate, thereby agitating the copper-containing waste liquid and increasing the efficiency of the equipment during the iron powder replacement process.

[0029] Furthermore, the inner bottom wall of the reaction barrel 1 is lower in the middle and higher on the outside. The bottom wall with a lower middle and higher outside can prevent the copper-containing waste liquid from remaining in the reaction barrel 1.

[0030] Furthermore, the height of the filter element 7 is half of the height of the support column 3. The design of a specific height facilitates the staff to collect copper powder.

[0031] Furthermore, an observation window 16 is provided on the side wall of the reaction barrel 1. The observation window 16 facilitates the staff to observe the internal situation of the reaction barrel 1.

[0032] Furthermore, stop valves can be installed on the liquid inlet pipe 4, the liquid outlet pipe 5, and the drain pipe 6 to control the opening and closing of the liquid inlet pipe 4, the liquid outlet pipe 5, and the drain pipe 6.

[0033] The present utility model is a copper-containing waste liquid purification and recovery device, and its working principle is described in conjunction with the accompanying drawings:

[0034] First, open the cover 13 to add iron powder, close the cover 13, introduce the copper-containing waste liquid into the reaction barrel 1 through the liquid inlet pipe 4, start the driving motor 14, and agitate the copper-containing waste liquid in the reaction barrel 1. Use iron powder to replace copper. After replacement, the copper-containing waste liquid is discharged into the waste liquid tank 2 through the liquid outlet pipe 5, and the replaced copper powder remains on the filter element 7 (inner filter screen 11). Start the hydraulic cylinder 9 to drive the filter element 7 to rise, pull out the bolt and remove the baffle 12, and use a brush to brush out and collect the copper powder on the filter element 7 through the notch. The purified copper-containing waste liquid is discharged through the drain pipe 6.

[0035] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
