It is currently mainly used for screening and gas, liquid filtration and other media separation under acid and alkaline environmental conditions. During the production process of nickel mesh, the nickel in the wastewater is a strong carcinogen, which will destroy the ecological balance of the water body if discharged into the water body. At present, the wastewater recovery device can remove nickel by adding flake caustic soda materials so that the hydroxide generated by the flake caustic soda materials will combine with nickel ions in the wastewater to form nickel hydroxide precipitates, thereby removing nickel and achieving the purpose of removing nickel from nickel-containing wastewater.

The nickel electroplating wastewater recycling and treatment device of the utility model is convenient for filtering impurities in the wastewater by arranging the filter assembly on the rotating shaft and the second filter screen on the connecting rod, and is also convenient for disassembling the filter screen at a later stage, so that the staff can clean up the impurities and increase the quality of the finished product.

[0004] Most of the existing technical solutions have the following defects: during stirring, the stirring rod is not well protected, which causes impurities to be excessively adsorbed on the stirring rod, resulting in cumbersome subsequent cleaning. Therefore, the utility model provides a wastewater recovery device for nickel mesh production to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a wastewater recovery device for nickel mesh production to solve the problem in the above-mentioned background technology that the stirring rod does not have a good protection function during stirring, resulting in impurities being excessively adsorbed on the stirring rod, causing the subsequent cleaning to be more complicated.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a wastewater recovery device for nickel mesh production, comprising a treatment box, a box cover fixedly installed on the outer side of the upper end of the treatment box by bolts, and a water inlet pipe arranged on the left side of the upper end surface of the box cover, and also comprising:

[0007] A filter screen is installed on the left side of the upper end of the treatment box, and a guide block is arranged directly below the filter screen and located on the left side of the inside of the treatment box. A mounting cylinder is fixedly installed on the inner wall end of the treatment box, and a guide cavity is arranged in the middle of the lower end of the mounting cylinder. A drainage pipe is arranged on the lower side of the front side of the treatment box;

[0008] The filter cartridge is arranged in the middle of the mounting cartridge, a driving motor is installed on the left side of the upper end surface of the box cover, and the output end of the driving motor is connected to a stirring rod located in the filter cartridge, and a feed port is installed on the right side of the upper surface of the box cover.

[0009] Preferably, the guide block is arranged at an angle, and a prefabricated through groove penetrating the left side of the installation tube is arranged at the right end of the guide block.

[0010] Preferably, the prefabricated through groove is connected to the installation tube, and a positioning column is fixedly installed on the bottom of the installation tube.

[0011] Preferably, a positioning hole adapted to the positioning column is opened inside the lower end of the filter cartridge, and the filter cartridge is connected to the positioning column by plugging through the positioning hole.

[0012] Preferably, the lower end of the filter cartridge is provided with a protruding structure in contact with the interior of the mounting cartridge, and the upper end of the filter cartridge is open, and the stirring rod forms a rotating structure with the filter cartridge via a bearing.

[0013] Preferably, the feed inlet is located just above the internal gap between the filter cylinder and the mounting cylinder and serves the purpose of feeding.

[0014] Preferably, the filter screen is connected to the processing box by plugging, and the filter aperture size of the filter screen is larger than the filter aperture size of the filter cartridge.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the wastewater recovery device produced by the nickel mesh has a good filtering function, and when stirring, it has a good protection function for the stirring rod to prevent impurities from being excessively adsorbed on the stirring rod;

[0016] 1. The filter mesh has a larger pore size than the filter cartridge. The filter mesh can perform preliminary filtration on the wastewater, which is convenient for removing large impurities. The filtered wastewater can be injected into the installation cartridge through the prefabricated slot under the action of the guide block. At the same time, the filter cartridge can filter the nickel hydroxide precipitate, so that the overall filtration function is better.

[0017] Furthermore, the caustic soda flake material is injected into the installation cylinder through the feed port and is located outside the filter cylinder. Then the drive motor is started so that the drive motor can drive the stirring rod to rotate in the filter cylinder, so that the filter cylinder has a better protection function for the stirring rod, and prevents impurities from being excessively adsorbed on the stirring rod. At this time, the stirring rod can speed up the flow rate of the wastewater in the installation cylinder, thereby speeding up the mixing of the caustic soda flake material and the wastewater, so that the hydroxide generated by the caustic soda flake material will combine with the nickel ions in the wastewater to generate nickel hydroxide precipitate, which makes it convenient for the filter cylinder to filter the nickel hydroxide precipitate;

[0018] 2. The filter cartridge is connected to the positioning column through the positioning hole by plugging, and the filter screen is connected to the treatment box by plugging. When the filter screen and the filter cartridge need to be cleaned, the box cover can be removed from the treatment box by bolts, and then the filter screen and the filter cartridge can be lifted up respectively. At this time, the filter screen can be separated from the treatment box, and the filter cartridge can be separated from the positioning column, so that the positioning column and the positioning hole can lose the installation function of the filter cartridge, thereby facilitating cleaning.
