Description

Technical Field

[0001] The utility model relates to the technical field of cooling tanks, in particular to a cooling tank device utilizing compressed air stirring. Background Art

[0002] Cooling tanks are equipment used in industrial production and laboratory research to cool and control the temperature of liquids. In industrial production, cooling tanks can cool chemical reactors, heat exchangers, generators and other equipment. In experiments, cooling tanks can be used to control the temperature of reactions and cool samples. In the Bayer process, the seed liquor of aluminum can be used to extract metallic gallium. In such a gallium-making workshop, qualified gallium-containing analytical liquid can be obtained after analysis by an analytical tower, and the liquid is sent to the evaporator for evaporation. After that, the evaporated mother liquor can be sent to the cooling tank for cooling. However, the evaporated mother liquor in the cooling tank cannot be evenly cooled during cooling, resulting in the coolant failing to reach the required temperature after treatment. It takes a long time to cool the evaporated mother liquor, which is a waste of time. Utility Model Content

[0005] Preferably, the rotating mechanism includes: a stirring blade, the stirring blade is fixedly mounted on the output end of the driving motor, and the output end of the driving motor passes through the outer surface of the cooling tank, the stirring blade is located directly below the cooling coil, and the cooling coil does not contact the stirring blade, one end of the cooling coil is fixedly mounted with a liquid inlet, and the liquid inlet is connected to the water outlet of the cooling tower, and one end of the cooling coil is fixedly mounted with a liquid outlet, and the liquid outlet is connected to the water inlet of the cooling tower.

[0006] By adopting the above technical scheme, cooled water is sent into the interior of the cooling coil through the liquid inlet, heat is exchanged through the cooling coil, the temperature of the evaporation mother liquid injected into the cooling tank is absorbed, and the liquid after absorbing heat is discharged from the cooling coil through the liquid outlet for further cooling, so that the temperature of the evaporation mother liquid in contact with the cooling coil is reduced, and the stirring blade is driven to rotate by starting the driving motor, so that the mother liquid in the cooling tank can quickly and more comprehensively contact with the cooling coil, and the evaporation mother liquid after cooling flows so that the evaporation mother liquid that has not been cooled contacts with the cooling coil, so that the evaporation mother liquid is cooled faster, and at the same time the temperature of the evaporation mother liquid in the cooling tank is made more uniform.

[0007] Preferably, a mounting plate is fixedly mounted on the outer surface of the cooling coil, and two sides of the mounting plate are slidably connected to the cooling trough, and the cooling trough and the mounting plate are fixed by screws.

[0008] By adopting the above technical solution, the cooling coil is fixed by installing a fixing plate so that the cooling coil will not be deformed and broken. At the same time, the cooling coil can be conveniently fixed inside the cooling tank, making it more convenient to clean or replace the cooling coil.

[0009] Preferably, a gas ejection mechanism is fixedly installed inside the cooling tank, and the gas introduced through the air inlet pipe causes the evaporated mother liquid in the cooling tank to tumble, so that the evaporated mother liquid can be further evenly cooled.

[0010] By adopting the above technical scheme, the evaporation mother liquor that has been in contact with the cooling coil and cooled can be brought upward by the ejected compressed air, and the evaporation mother liquor that has not been cooled can be rolled down to continue to contact the cooling coil, thereby accelerating the cooling of the evaporation mother liquor. At the same time, the evaporation mother liquor can be stirred and rolled, so that the evaporation mother liquor can be cooled more evenly.

[0011] Preferably, the gas ejection mechanism includes: an outlet pipe, which is a ring-shaped body composed of two circular rings, and the outlet pipe is connected to the inlet pipe, the outlet pipe and the cooling trough are concentrically designed, and the inner surface of the cooling trough is in contact with the outer surface of the outlet pipe, the outlet pipe and the drive motor are concentrically designed, and the output end of the drive motor passes through the center of the outlet pipe, the outlet pipe and the stirring blade are concentrically designed, and the stirring blade is located between the outlet pipe and the cooling coil, and the outer surface of the outlet pipe is evenly provided with outlet holes.

[0016] By adopting the above technical solution, the bracket can be quickly fixed to the outer surface of the liquid storage tank through the socket groove, and the plastic shielding film can prevent the evaporated mother liquid in the cooling tank from splashing out, so that the splashed evaporated mother liquid can only flow down the plastic shielding film and fall into the liquid storage tank.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the cooling tank device using compressed air stirring:

[0018] 1. The evaporation mother liquid is discharged into the cooling tank through the external pipeline, and the cooling water enters the cooling coil through the liquid inlet to absorb the temperature of the evaporation mother liquid for heat replacement. Then, the heat-absorbing cooling liquid is discharged into the cooling tower through the liquid outlet for circulation. The stirring blades are driven to rotate with the rotation of the driving motor to push away the cooled evaporation mother liquid, so that the cooling coil is always in contact with the evaporation mother liquid that has not been cooled, so that the evaporation mother liquid is cooled faster and more evenly;

[0019] 2. By injecting compressed air into the air inlet pipe, the compressed air is ejected from the air outlet holes along the air outlet pipe. Through the double-ring design of the air pipe, the air outlet holes are evenly distributed inside the cooling tank. The gas ejected from the air outlet holes drives the evaporation mother liquid to roll up, and brings the cooled evaporation mother liquid to the top of the cooling tank, so that the evaporation mother liquid that has not been cooled down descends and contacts with the cooling coil for cooling. At the same time, the evaporation mother liquid is driven to roll by the compressed air so that the evaporation mother liquid can be evenly mixed and cooled.

[0020] 3. When the evaporation mother liquid in the cooling tank rolls and rotates, it will inevitably splash or overflow the cooling tank. At this time, the overflowing evaporation mother liquid will fall into the interior of the storage tank, and the splashing evaporation mother liquid will be blocked by the plastic shielding film and fall into the storage tank. It only takes time for people to open the manual drain valve or use containers and water pumps to return the evaporation mother liquid to the cooling tank to reduce the loss of the evaporation mother liquid and the pollution to the outside world.
