Description

Technical Field

[0001] The utility model belongs to the technical field of flash cooling, and in particular relates to a flash cooling device for a nickel sulfate solution. Background Art

[0002] The structure of a flash tank is generally composed of a tank body, a feed pipe, a discharge pipe, a steam pipe, an exhaust pipe, etc. The feed pipe and the discharge pipe are used to input and output liquid substances into and out of the flash tank, respectively, while steam is used to input steam into the tank body, and the exhaust pipe is used to discharge the gas in the flash tank. The boiling point of the substance increases with increasing pressure and decreases with decreasing pressure. In this way, the high-pressure and high-temperature fluid can be reduced in pressure to reduce its boiling point and enter the flash tank. At this time, the fluid temperature is higher than the boiling point under this pressure. The fluid boils and vaporizes rapidly in the flash tank, and the two phases are separated.

[0003] After the nickel sulfate solution undergoes flash evaporation, the temperature is relatively high. At this time, the nickel sulfate solution will be cooled when it leaves the flash tank, but the existing cooling device has a poor effect on the nickel sulfate solution, resulting in insufficient cooling and inability to be directly output to the liquid storage device.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content

[0005] In order to solve the above problems, the purpose of the utility model is to provide a flash evaporation device with strong cooling capacity.

[0006] To achieve the above-mentioned purpose, the utility model proposes a flash cooling device for nickel sulfate solution, characterized in that it comprises a flash tank, on which a solution input pipe, a liquid outlet pipe and a steam discharge pipe are arranged, and valves are installed on the solution input pipe, the liquid outlet pipe and the steam discharge pipe, and a cooling device is arranged at one end of the liquid outlet pipe, and the cooling device comprises a retention tank, which is fixedly connected to the liquid outlet pipe, and the retention tank is communicated with the liquid outlet pipe, and one end of the retention tank is fixedly connected to a shell, and a circular through groove is arranged on the shell, and the retention tank is fixed on the inner wall of the circular through groove, and one side of the retention tank is opened, and one side of the retention tank is rotatably connected to a rotating plate, and four circular through holes are arranged on the rotating plate, and one side of the shell is rotatably connected to an output pipe, and the output pipe is communicated with the shell, and a connecting pipe is connected to the shell, and the other end of the connecting pipe is connected to a cold air machine.

[0007] In one example, one side of the rotating plate is fixedly connected to four transverse tubes, the transverse tubes are aligned with four circular through holes, the outer sides of the four transverse tubes are fixedly connected to a cooling tank, one side of the cooling tank is connected to an inclined tube, the four inclined tubes are connected to an output pipe, one side of the transverse tube is conical, the center of the transverse tube and the center of the cooling tank are on the same axis, and the connection position between the inclined tube and the cooling tank is located at the edge of the cooling tank, close to the center of the rotating plate.

[0008] In one example, all of the transverse tubes are fixedly connected to the inclined baffle at one end located in the cone, and the edge of the circular through groove is close to the edge of the retention tank.

[0009] In one example, one side of the housing is fixedly connected to the motor, the main shaft of the motor is fixedly connected to the gear, the outer side of the output pipe is fixedly connected to the gear ring, and the gear is meshed with the gear ring.

[0010] In one example, one end of the steam exhaust pipe is connected to the condenser, one end of the condenser is connected to the air outlet pipe, a vertical pipe is fixedly connected between the shell and the condenser, the vertical pipes are connected to the shell and the condenser, and a water outlet hole is provided on the side wall of the condenser.

[0011] In one example, the inner wall of the condenser tube is fixedly connected to a plurality of condenser plates, and all of the condenser plates are arranged in an array.

[0012] The flash cooling device for nickel sulfate solution proposed by the utility model can bring the following beneficial effects:

[0013] First, by setting a cooling tank, the solution passes through the interception tank and the flow rate is reduced. When the circular through hole rotates to the lowest point, the solution passes through the circular through hole and the horizontal tube into the cooling tank. Then the rotating plate continues to rotate from the lowest point to the highest point. When it is at the highest point, the solution enters the output pipe through the inclined tube and is discharged. During the rotation of the rotating plate, the cooling tank is cooled by the cold air inside the shell, thereby cooling the solution inside. In this process, the four cooling tanks are operated in turn to continuously cool the liquid in the interception tank and then discharge it. The time passing through the shell becomes longer, and the cooling time becomes longer, thereby improving the cooling effect.

[0014] Secondly, by setting up a condenser, steam enters the condenser. Since the air conditioner is in the on state, cold air is continuously transported into the shell. The cold air in the shell enters the condenser through the vertical pipe. When the steam meets the cold air, condensation occurs. The condensed water falls into the condenser and flows out through the water outlet. The staff only needs to collect it through the water outlet and recycle the water in the steam through the cold air, thus saving water resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figure 1 to Figure 5As shown, an embodiment of the utility model proposes a flash cooling device for nickel sulfate solution, comprising a flash tank 1, on which a solution input pipe 2, a liquid outlet pipe 3, and a steam discharge pipe 4 are arranged, valves are installed on the solution input pipe 2, the liquid outlet pipe 3, and the steam discharge pipe 4, a cooling device 5 is arranged at one end of the liquid outlet pipe 3, the cooling device 5 comprises a retention tank 51, the retention tank 51 is fixedly connected to the liquid outlet pipe 3, the retention tank 51 is communicated with the liquid outlet pipe 3, one end of the retention tank 51 is fixedly connected to a shell 52, a circular through groove is arranged on the shell 52, the retention tank 51 is fixed on the inner wall of the circular through groove, one side of the retention tank 51 is opened, one side of the retention tank 51 is rotatably connected to a rotating plate 53, the rotating plate 53 is provided with four circular through holes, one side of the shell 52 is rotatably connected to an output pipe 54, the output pipe 54 is communicated with the shell 52, the shell 52 is connected to a connecting pipe 55, and the other end of the connecting pipe 55 is connected to a cold air Machine 56; nickel sulfate solution enters the flash tank 1 through the solution input pipe 2 for flash concentration, flows out through the liquid outlet pipe 3 below after flash evaporation, and the steam is discharged through the steam discharge pipe 4 above. The nickel sulfate solution enters the retention tank 51 through the liquid outlet pipe 3, and the liquid flow is stopped and gathered in the retention tank 51. At this time, the rotating plate 53 is rotated. When the circular through hole rotates to the lowest point, the solution will enter the range of the shell 52 through the circular through hole. At this time, the air conditioner 56 passes the cold air into the shell 52 through the connecting pipe 55. When the solution passes through the shell 52 and flows out through the output pipe 54, the cold air in the shell 52 cools the solution and reduces the temperature. The solution is blocked by the retention tank 51, the flow speed is reduced, the time it takes to pass through the shell 52 is prolonged, and the cooling time is prolonged, thereby improving the cooling effect and avoiding the rapid passage of the liquid, resulting in too short a cooling time and an unobvious cooling effect.

[0028] Specifically, one side of the rotating plate 53 is fixedly connected to four transverse tubes 6, the transverse tubes 6 are aligned with the four circular through holes, the outer sides of the four transverse tubes 6 are fixedly connected to the cooling tank 7, one side of the cooling tank 7 is connected to the inclined tube 8, and the four inclined tubes 8 are connected to the output pipe 54. One side of the transverse tube 6 is conical, and the center of the transverse tube 6 and the center of the cooling tank 7 are on the same axis. The connection position of the inclined tube 8 and the cooling tank 7 is located at the edge of the cooling tank 7, close to the center of the rotating plate 53; when the circular through hole rotates to the lowest point, the solution passes through the circular through hole and the transverse tube 6 into the cooling tank 7, and then The rear rotating plate 53 continues to rotate from the lowest point to the highest point. When it is at the highest point, the solution enters the output pipe 54 through the inclined tube 8 and is discharged. During the rotation of the rotating plate 53, the cooling tank 7 is cooled by the cold air inside the shell 52, thereby cooling the internal solution. In this process, the four cooling tanks 7 are operated in turn to continuously cool the liquid in the retention tank 51 and then discharge it. The liquid stays in the cooling tank 7 for cooling to ensure the cooling effect, and at the same time, the liquid is continuously transported out to avoid liquid accumulation in the retention tank 51.

[0029] Specifically, all the transverse tubes 6 are fixedly connected to the inclined baffle 9 at one end of the cone, and the edge of the circular through groove is close to the edge of the retention tank 51; after the liquid enters the cooling tank 7, during the process of rotating from the lowest point to the highest point, the liquid moves in the cooling tank 7, and the baffle can block the liquid to a certain extent to prevent a large amount of solution from flowing back through the transverse tube 6 during the rotation process, affecting the cooling and transportation of the liquid.

[0030] Specifically, one side of the shell 52 is fixedly connected to the motor 10, the main shaft of the motor 10 is fixedly connected to the gear 11, the outer side of the output pipe 54 is fixedly connected to the gear ring 12, and the gear 11 is meshed with the gear ring 12; the motor 10 drives the gear 11 and the gear ring 12 to drive the output pipe 54 to rotate, and then drives the rotating plate 53 to rotate, which is more convenient for cooling and transporting the liquid. The gear 11 and the gear ring 12 are located inside the shell 52, which is convenient for maintaining a low temperature environment inside the shell 52.

[0031] Specifically, one end of the steam discharge pipe 4 is connected to the condenser 13, and one end of the condenser 13 is connected to the air outlet pipe 14. A vertical pipe 15 is fixedly connected between the shell 52 and the condenser 13. The vertical pipe 15 is connected to the shell 52 and the condenser 13, and a water outlet hole 16 is provided on the side wall of the condenser 13; steam enters the condenser 13 through the steam discharge pipe 4. Since the air conditioner 56 is in the on state, cold air is continuously transported into the shell 52. The cold air in the shell 52 enters the condenser 13 through the vertical pipe 15. When the steam meets the cold air, condensation is performed, and the condensed water falls into the condenser 13 and flows out through the water outlet hole 16. The staff only needs to collect it through the water outlet hole 16, and the water in the steam is recovered through the cold air, thereby saving water resources. Since the cold air continuously enters the condenser 13, the condensed water is blown by the cold air in the vertical pipe 15 and will not flow into the shell 52 through the vertical pipe 15.

[0032] Specifically, the inner wall of the condenser tube 13 is fixedly connected to a plurality of condenser plates 17, and all the condenser plates 17 are arranged in an array; after the cold air enters the condenser tube 13, the temperature of the condenser plates 17 is lowered, and the condenser plates 17 block the outlet pipe 14. The condenser plates 17 come into contact with the steam to condense, thereby preventing the steam from directly passing through the outlet pipe 14 and flowing out, causing waste.

[0033] Working principle: Nickel sulfate solution enters the flash tank 1 through the solution input pipe 2 for flash concentration. After flash, it flows out through the liquid outlet pipe 3 at the bottom, and the steam is discharged through the steam discharge pipe 4 at the top. The nickel sulfate solution enters the retention tank 51 through the discharge pipe, and the motor 10 drives the gear 11 and the gear ring 12 to drive the output pipe 54 to rotate, thereby driving the rotating plate 53 to rotate. When the circular through hole rotates to the lowest point, the solution will enter the cooling tank 7 through the circular through hole, and then the rotating plate 53 will continue to rotate from the lowest point to the highest point. When it is at After the highest point, the solution enters the output pipe 54 through the inclined tube 8 and is discharged. During the rotation of the rotating plate 53, the cooling tank 7 is cooled by the cold air inside the shell 52, and the steam enters the condenser 13 through the steam discharge pipe 4. Since the air conditioner 56 is in the on state, cold air is continuously transported into the shell 52. The cold air in the shell 52 enters the condenser 13 through the vertical pipe 15. When the steam meets the cold air, condensation is performed, and the condensed water falls into the condenser 13 and flows out through the water outlet 16. The staff only needs to collect it through the water outlet 16.
