[0007] Adsorption tower: the main body is made of carbon steel material lined with corrosion-resistant material (such as glass steel), and the tower is filled with high-efficiency adsorbent.

[0008] Desorption device: when the adsorbent reaches adsorption saturation, it needs to be desorbed to restore its adsorption performance.

[0009] At present, the traditional zinc concentrate flotation of precious metal wastewater treatment method has many drawbacks. Some treatment processes are too simple, relying only on single sedimentation or filtration step, which is difficult to effectively remove various impurities and heavy metal ions in wastewater, resulting in treated wastewater cannot be discharged. The structure of some treatment devices is complex, and the operation is cumbersome, which requires professional technical personnel to operate and maintain, increasing the operating cost of enterprises. Moreover, most of the existing treatment equipment lacks flexibility, and it is difficult to adjust the treatment mode in time according to the different characteristics of wastewater, which cannot meet the diversified treatment demand. In the replacement of filter parts, the traditional device is often not designed reasonably, and the replacement process is time-consuming and laborious, which affects the efficiency and continuity of wastewater treatment.

The structure of some treatment devices is complex, and the operation is cumbersome, which requires professional technical personnel to operate and maintain, thereby increasing the operation cost of enterprises. Moreover, most of the existing treatment equipment lacks flexibility, and it is difficult to adjust the treatment mode in time according to different characteristics of wastewater, and cannot meet diversified treatment requirements. In the replacement of the filter part, the traditional device is often not reasonably designed, and the replacement process is time-consuming and laborious, which affects the efficiency and continuity of wastewater treatment. The overall idea is as follows:

[0029] In view of the problems in the prior art, the utility model provides a zinc concentrate flotation precious metal wastewater treatment device, including the sedimentation tank 23, the sedimentation tank 23 is opened and is used for the settlement of suspended solids and part of heavy metal ions and is provided with the sedimentation groove, the design of the sedimentation groove is extremely key, it provides a relatively stable environment for wastewater, so that the suspended solids are naturally settled to the groove bottom under the action of gravity, and part of the heavy metal ions will react with certain substances in the wastewater, and form a precipitate and settle down, thereby effectively reducing the impurity content in the wastewater.

[0030] The two limiting grooves 24 are formed in the sedimentation tank 23, and the lifting rod 26 is slidably installed in the two limiting grooves 24 of the sedimentation tank 23. The filter box 25 is fixedly installed at the lower end of the lifting rod 26. The limiting grooves 24 precisely limit the lifting rod 26, so that the lifting rod 26 can only slide in a specific track, and deviation or shaking of the lifting rod 26 during movement is avoided. The lifting rod 26 facilitates the operation of the filter box 25. The operator can take out the filter box 25 from the sedimentation tank 23 by pulling the lifting rod 26, so that the filter box 25 can be cleaned or replaced, the maintenance efficiency is greatly improved, and the filter box 25 is designed as a filter screen. The filter screen gap is smaller than that of the filter plate 15, so that the wastewater can be further finely filtered, smaller impurity particles can be effectively intercepted, and the precision of wastewater treatment is improved.

[0031] The waste liquid inlet 21 is fixedly installed at the side end of the sedimentation tank 23, and the grid plate 22 is fixedly installed in the waste liquid inlet 21. The waste liquid inlet 21 is the inlet of the wastewater into the entire treatment device, and plays a role in guiding the flow direction of the wastewater. The grid plate 22 is the first line of defense for wastewater treatment, and its role cannot be underestimated. It can preliminarily intercept larger impurity particles in the wastewater, such as branches, plastic fragments, etc. These large particles are prevented from entering the subsequent treatment link, so as to avoid blocking or damaging the subsequent equipment, thereby ensuring the stable operation of the entire treatment device.

[0032] The filter plate 15 is slidably installed in the waste liquid inlet 21. The installation plate 11 is arranged at the upper end of the filter plate 15. The two sliding grooves 12 are formed in the installation plate 11. The two sliding grooves 12 of the installation plate 11 and the filter plate 15 are provided with two groups of quick release mechanisms. The gap of the filter plate 15 is smaller than that of the grid plate 22, so that the wastewater preliminarily filtered by the grid plate 22 can be further filtered, and the fine impurities in the wastewater can be further removed. The installation plate 11 provides a support structure for the installation and fixation of the filter plate 15, and the sliding groove 12 provides a track for the operation of the quick release mechanism.

[0034] Working principle:

[0035] Firstly, according to the actual characteristics of the wastewater, the appropriate filter plate 15 can be selected flexibly, the wastewater first passes through the waste liquid inlet 21, the grid plate 22 in the waste liquid inlet 21 can preliminarily filter the wastewater and intercept larger impurities, then the wastewater flows through the filter plate 15, since the gap of the filter plate 15 is smaller than that of the grid plate 22, it can further filter out smaller impurities, realizing secondary filtration, the wastewater filtered twice flows to the filter box 25, the filter box 25 adopts a filter screen design, the filter screen gap is smaller, which can further filter the wastewater, the wastewater filtered by the filter box 25 finally flows into the sedimentation tank 23, and the sedimentation tank 23 completes the settlement treatment of suspended solids and part of heavy metal ions, thereby realizing the purification of the wastewater.

[0036] Second, if the filter plate 15 needs to be replaced in order to better handle wastewater of different characteristics, the operation steps are as follows: first, unscrew the bolts connecting the mounting plate 11 and the waste liquid inlet 21, and remove the fixed connection between the two; then, pull the two L-shaped latches 14 respectively, at this time, under the elastic action of the reset spring 13, the L-shaped latches 14 will be separated from the connecting plug plate 16, and the limiting between the connecting plug plate 16 and the mounting plate 11 will be removed, in this way, the filter plate 15 can be separated from the mounting plate 11, then, select the appropriate size of the filter plate 15, insert its connecting plug plate 16 into the sliding slot 12 of the mounting plate 11, loosen the L-shaped latches 14, under the push of the reset spring 13, the L-shaped latches 14 will be inserted into the connecting plug plate 16, and the limiting and fixing of the filter plate 15 will be realized again, the replacement of the filter plate 15 is completed, and the device can continuously and efficiently handle wastewater of different characteristics.

[0037] Finally, it should be noted that: obviously, the above examples are only examples for clearly illustrating the utility model, and are not limited to the implementation. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to enumerate all the implementation. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
