However, these methods have problems such as low efficiency, secondary pollution, high cost, and high requirements for operators in treating graphite wastewater, making it difficult to achieve stable and standard discharge of wastewater.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0028] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0030] See also Figure 1-Figure 6 As shown, the utility model is a treatment system for cathode graphite wastewater of new energy batteries, comprising a raw water tank 1, a low-temperature evaporation device 2 is fixedly installed at one end of the raw water tank 1, a concentrated water tank 3 is fixedly installed at the other end of the low-temperature evaporation device 2, and a distilled water tank 4 is fixedly installed at one end of the concentrated water tank 3;

[0031] The low-temperature evaporation equipment 2 includes an evaporation tank 201, a condensation tank 202, a cooling water tank 203, a vacuum pump 204, a diaphragm pump 205, and a heat pump 206, wherein the evaporation tank 201 is fixedly installed on the raw water tank 1, the concentrated water tank 3 is fixedly installed on the diaphragm pump 205, and the distilled water tank 4 is fixedly installed on the condensation tank 202.

[0032] The graphite wastewater stored in the raw water tank 1 is pumped into the evaporation tank 201 under the vacuum suction of the low-temperature vacuum evaporation equipment 2. The compressor generates heat to heat the wastewater in the evaporation tank 201. Under the vacuum state, the wastewater temperature rises to about 37°C, causing the wastewater to boil and evaporate rapidly, thereby separating the pollutants from the water vapor. Most of the pollutants are concentrated in the concentrated water, and the water vapor is discharged into the clean water tank after being condensed into water for subsequent treatment. This system has a short process flow and few equipment; no additional reagents are required, and there is no secondary pollution; high concentration ratio, water production rate can reach 92%, and the degree of automation is high.

[0033] Among them: raw water tank, made of PE, used to store graphite wastewater; low-temperature evaporation equipment, used to evaporate and concentrate wastewater; evaporation tank, made of 316 stainless steel, used to evaporate and concentrate wastewater; condensation tank, made of 316 stainless steel, used to condense steam into liquid and temporarily store distilled water; cooling water tank, made of 316 stainless steel, used to store cooling water; vacuum pump, made of 304 stainless steel, used to evacuate the evaporation tank; diaphragm pump, made of PP plastic, used to discharge concentrated liquid; heat pump, made of carbon steel, used to provide heat for wastewater; concentrated water tank, made of PE, used to store concentrated wastewater; distilled water tank, made of PE, used for clean water after distillation.

[0034] In addition, in specific applications, the evaporation temperature is preferably 37 degrees. The low evaporation temperature is not easy to produce scale and there is no hidden danger to operational safety. The process flow is short and the equipment is small. There is no need to add chemicals, no secondary pollution, and the effluent is stable and of good quality.

[0035] In one embodiment, a distilled water tank 4, as described above, comprises an outer shell 401, a connection port 402 is fixedly mounted on the top of the outer shell 401, the connection port 402 is fixedly mounted on the condensation tank 202, a condensation pipe 403 is fixedly mounted at one end of the connection port 402 and located in the inner cavity of the outer shell 401, and the other end of the condensation pipe 403 passes through the circumferential surface of the outer shell 401.

[0036] A heat dissipation pipe 404 is fixedly installed in the inner cavity of the shell 401 , and the other end of the heat dissipation pipe 404 passes through the circumferential surface of the shell 401 . A driving motor 405 is arranged at the bottom of the heat dissipation pipe 404 , and the driving motor 405 is fixedly installed on the shell 401 .

[0037] Two first synchronous wheels 406 are fixedly installed at the output end of the driving motor 405, and a synchronous belt 407 is rotatably installed at one end of the two first synchronous wheels 406, and a second synchronous wheel 408 is rotatably installed at the other end of the synchronous belt 407, and a rotating rod 409 is fixedly installed on the top of the two second synchronous wheels 408.

[0038] A plurality of stirring rods 410 are fixedly mounted on the circumferential surface of the rotating rod 409 , and a fan blade 411 is fixedly mounted on the output end of the driving motor 405 .

[0039] The fan blade 411 is located in the inner cavity of the heat dissipation pipe 404 .

[0040] The water vapor in the condensation tank 202 first enters the condensation tube 403, and then condenses into water in the housing 401 filled with water at a lower temperature through the condensation tube 403, and then goes out from the other end of the condensation tube 403; when the water temperature inside the housing 401 increases, the heat will gather around the heat dissipation tube 404, and then the output end of the driving motor 405 will drive the fixedly installed fan blade 411 to rotate, and the rotation of the fan blade 411 will blow the temperature in the heat dissipation tube 404 out of the housing 401 from the other port of the heat dissipation tube 404;

[0041] At the same time, the output end of the driving motor 405 will also drive the two first synchronous wheels 406 fixedly installed to rotate, because one end of the two first synchronous wheels 406 is rotatably installed with a synchronous belt 407. Then the two first synchronous wheels 406 will respectively drive the synchronous belts 407 rotatably installed to rotate, and then the synchronous belt 407 will drive the second synchronous wheel 408 rotatably installed to rotate, and then the rotating rod 409 fixedly installed with the second synchronous wheel 408 will also rotate together, and then the rotating rod 409 will drive the fixedly installed several stirring rods 410 to rotate, so the several stirring rods 410 will rotate in the inner cavity of the shell 401, so that the water in the shell 401 has the effect of rotating back and forth, so that the water and the condenser 403 are perfectly fitted to ensure better heat dissipation of the water vapor in the condenser 403.

[0042] Thus, the output end of the driving motor 405 is driven to drive the fan blade 411 to rotate, and the rotation of the fan blade 411 will blow the temperature in the heat dissipation pipe 404 out of the housing 401 from another port of the heat dissipation pipe 404, thereby avoiding the problem of water rising in the inner cavity of the housing 401 and poor condensation effect on the condensation pipe 403;

[0043] The output end of the driving motor 405 will also drive the two first synchronous wheels 406 to rotate, so that the several stirring rods 410 will rotate in the inner cavity of the shell 401, causing the water in the shell 401 to rotate back and forth, allowing the water to fit perfectly with the condenser 403, so as to ensure better heat dissipation of the water vapor in the condenser 403.
