Description

Technical Field

[0001] The utility model relates to the technical field of mineral processing reagent wastewater treatment, in particular to a processing device for production wastewater. Background Art

[0002] Mineral processing reagents mainly refer to collectors, foaming agents, inhibitors, flocculants, regulators, extractants used in hydrometallurgy, matrix improvers for extraction, diluents, etc., involving hundreds of inorganic or organic synthetic substances. There are hundreds of chemical reagents that are harmful to the environment, such as cyanide, hydrogen sulfide, phosphine and fluoride. Therefore, the treatment of wastewater from the production of mineral processing reagents is very important.

[0003] The patent with publication number CN213231833U discloses a treatment device for wastewater produced by mineral processing reagents, which first neutralizes the wastewater by setting a neutralization box and a filter box, and then uses the filter box to circulate and filter the neutralized wastewater, thereby improving the treatment effect. However, since the device is provided with two boxes, it occupies a large area, and the filter assembly is arranged before the circulation pump, the impurity particles in the wastewater are easy to damage the circulation pump, thereby affecting the service life of the circulation pump. Secondly, the filter layer of the circulation assembly is located inside the filter box, which is troublesome to disassemble and clean. In addition, since the neutralization reaction generates a large amount of heat, the heat cannot be recycled, resulting in waste, and therefore, further improvement is needed. Utility Model Content

[0026] A hopper 13 is fixedly connected to the top wall of the processing box 3. A neutralizing agent can be added into the processing box 3 through the hopper 13.

[0027] like Figure 2 As shown, the stirring assembly 4 includes a motor 41 fixed to the middle of the upper surface of the processing box 3, a vertical shaft 42 is fixedly connected to the bottom driving end of the motor 41, and a plurality of stirring rods 43 are fixed to the surface of the vertical shaft 42.

[0028] The motor 41 can drive the stirring rod 43 to rotate inside the treatment box 3 to stir the wastewater and the neutralizing agent and increase the reaction speed.

[0029] like Figure 1-Figure 3 As shown, the filter assembly 7 includes a disc 71 fixed to the top of the vertical pipe 6, and an annular support plate 72 is fixed to the inner wall of the disc 71, an annular frame plate 73 is provided on the upper surface of the support plate 72, a filter screen 74 is fixed inside the annular frame plate 73, and the lower surface of the cover plate 8 is in contact with the top of the disc 71 and the top of the annular frame plate 73.

[0030] When the neutralized wastewater is discharged from the bottom pipe 10 , it will pass through the filter screen 74 , and the filter screen 74 can be used to filter out particulate impurities in the wastewater. The filtered water will enter the temporary storage box 2 along the vertical pipe 6 .

In this process, cold water can be introduced from the cold water pipe 14, and the cold water will be heated by the heat released by the neutralization reaction after entering the annular pipe 16, and the heated water will be discharged from the hot water pipe 15.
