Technical Field

[0001] The utility model belongs to the technical field of drainage cooling, in particular to an automatic mixed cooling drainage device. Background Art

[0002] In the laboratory, many items need to be sterilized in an autoclave before they can be used. The autoclave uses steam for sterilization, which will discharge a large amount of high-temperature soda-water mixture in a short time. If the high-temperature soda-water mixture is discharged directly through the pipe, it will cause serious damage to the municipal drainage pipe. Therefore, before discharge, the high-temperature soda-water mixture needs to be cooled to about 40°C in a short time through a cooling drainage device before it can be discharged into the municipal pipe.

[0003] At present, the most common cooling measure in laboratories is to keep the tap water in a normally open state, use the tap water to cool the high-temperature steam-water mixture, and then manually open the valve to discharge it. However, after a long period of research, it was found that this cooling method would waste a lot of tap water and be costly, and on the other hand, it would also bring great inconvenience to laboratory operation and maintenance personnel. Therefore, it is urgent to improve the existing cooling and drainage device and provide an automatic mixed cooling drainage device. Summary of the invention

[0004] The purpose of the utility model is to provide a cooling and drainage device with reasonable design, simple structure, automatic mixing of cold and hot water to a set temperature, and then automatic water replenishment and drainage, good cooling effect, and easy operation, so as to solve the problems existing in the prior art.

[0008] As a preferred embodiment, an exhaust valve is fixedly installed at the top of the cooling tank.

[0009] As a preferred embodiment, the stirring and mixing assembly includes a fixed rod, a stirring shaft, a first conical tooth, a motor, a mounting rod, a support block and a second conical tooth. The fixed rod is located at the middle position inside the cooling tank, and both ends of the fixed rod are welded and fixed to the inner wall of the cooling tank. A stirring shaft is installed on the middle of the fixed rod through a bearing. A first conical tooth is fixedly connected to the top of the stirring shaft. The motor is fixedly installed on the outer wall of the left side of the cooling tank. An output end of the motor is fixedly connected to the mounting rod.

[0023] Based on the above structure, the hot water inlet pipe 4 and the cold water inlet pipe 5 are both located on the same side of the cooling tank 1, the drain pipe 7 is located on the other side of the cooling tank 1, and a sewage pipe 11 is embedded in the bottom of the cooling tank 1, and a fourth solenoid valve 12 is installed on the outside of the sewage pipe 11.

[0024] In this embodiment, by opening the fourth solenoid valve 12 , impurities remaining in the cooling tank 1 can be discharged through the sewage pipe 11 , so that the interior of the cooling tank 1 can be cleaned regularly.

[0025] On the basis of the above structure, an exhaust valve 3 is fixedly installed at the top of the cooling tank 1.

[0026] In this embodiment, by installing the exhaust valve 3, when the high-temperature hot water mixture enters the cooling tank 1 through the hot water inlet pipe 4, the gas therein can be directly released into the external environment through the exhaust valve 3.

[0027] On the basis of the above structure, the stirring and mixing assembly 9 includes a fixed rod 91, a stirring shaft 92, a first conical tooth 93, a motor 94, a mounting rod 95, a support block 96 and a second conical tooth 97. The fixed rod 91 is located at the middle position inside the cooling tank 1, and both ends of the fixed rod 91 are welded and fixed to the inner wall of the cooling tank 1. A stirring shaft 92 is installed on the middle part of the fixed rod 91 through a bearing. A first conical tooth 93 is fixedly connected to the top of the stirring shaft 92. The motor 94 is fixedly installed on the left outer wall of the cooling tank 1, and an output end of the motor 94 is fixedly connected to a mounting rod 95. A support block 96 is sleeved on the outer side of the mounting rod 95 through a bearing, and a second conical tooth 97 is fixedly connected to an end of the mounting rod 95 away from the motor 94.

[0028] In this embodiment, through the arrangement of the support block 96, the mounting rod 95 can be supported, the stability of the state of the mounting rod 95 during long-term use can be improved, and deformation can be avoided.

[0029] On the basis of the above structure, the longitudinal section of the stirring shaft 92 is in the shape of "丰", and the first conical tooth 93 and the second conical tooth 97 are meshed with each other.

[0030] In this embodiment, by using the mutually meshed first conical tooth 93 and second conical tooth 97, when the motor 94 is started to control the mounting rod 95 to drive the second conical tooth 97 to rotate, the first conical tooth 93 can drive the stirring shaft 92 to rotate, which is convenient for the rapid mixing of cold and hot water and for quickly reducing the water temperature.

[0033] The working principle of the present utility model is as follows:

[0034] When in use, firstly, each pipeline is connected to each pipeline interface on the cooling tank 1 by means of existing technology, and then the first solenoid valve 13 is opened, and the high-temperature hot water mixture enters the cooling tank 1 through the hot water inlet pipe 4. The gas in the high-temperature hot water mixture can be directly released into the external environment through the exhaust valve 3 on the top of the cooling tank 1. The water temperature is detected by the temperature sensor 10. When the water temperature is higher than the set temperature of the controller 2, the second solenoid valve 6 can be opened, and cold water can be input into the cooling tank 1 through the cold water inlet pipe 5. By mixing a large amount of cold water with the high-temperature hot water, the water temperature can be quickly reduced. Through the temperature sensor 10 monitoring, when the water temperature is lower than the set temperature of the controller 2, the second solenoid valve 6 can be controlled to be closed, and the third solenoid valve 8 can be controlled to be opened, and the water can be safely discharged into the municipal pipeline through the drain pipe 7;

[0035] Different from the conventional method of normally opening cooling water, the present device monitors the temperature sensor 10. When the water temperature is higher than the set value of the controller 2, the third solenoid valve 8 is closed, and the second solenoid valve 6 is opened to input cold water. When the water temperature is lower than the set value of the controller 2, the second solenoid valve 6 is closed to stop the cold water input, and the third solenoid valve 8 is opened to drain water through the drain pipe 7. This can solve the problem of high-temperature hot water mixture discharge in the laboratory, that is, prevent the waste of tap water, and save the time of scientific researchers.

[0036] Moreover, when mixing cold and hot water, the motor 94 can also be turned on to control the mounting rod 95 and the second conical tooth 97 to rotate rapidly, and the first conical tooth 93 meshing with the second conical tooth 97 can be used to control the stirring shaft 92 to rotate rapidly inside the cooling tank 1, so as to facilitate the rapid mixing of cold and hot water, facilitate the rapid reduction of the water temperature, and facilitate the temperature sensor 10 to monitor the accurate water temperature, avoid excessive cold water input, and play a certain role in saving water resources. Finally, the fourth solenoid valve 12 can be opened regularly to facilitate the discharge of impurities remaining in the cooling tank 1 through the drain pipe 11, so as to facilitate regular cleaning of the inside of the cooling tank 1.

[0037] The above are only preferred specific embodiments of the utility model and are not intended to limit the protection scope of the utility model; any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the protection scope determined by the claims.
