Technical Field

[0001] The utility model relates to the technical field of cooling water circulation, in particular to an automatic cooling water conversion circulation device. Background Art

[0002] Cooling water refers to water used to lower the temperature of the object being cooled. There are mainly circulating cooling water, direct cooling water, indirect cooling water, etc. Among them, circulating cooling water refers to cooling water that returns to the cooling structure for cooling after heat exchange, and is recycled after necessary treatment. Direct cooling water refers to cooling water that is used only once and then discharged during the cooling process. Indirect cooling water refers to cooling water that indirectly exchanges heat with the cooled material through heat exchange equipment. With the development of air conditioning cold source technology and the requirement of water conservation, direct cooling is no longer allowed in cooling water systems. The cooling water of water-cooled chillers and packaged air conditioners is recycled, and the condensation waste heat of the chiller should also be utilized as much as possible through cooling water; especially in equipment or processes that require continuous cooling, such as cooling towers, cooling units, processing machine tools, etc.

[0003] Currently in the market, the treatment of cooling water cannot achieve the effect of automatic conversion, and does not have the function of cooling water recycling, resulting in waste of water resources and energy consumption, which is not conducive to environmental protection. Therefore, it is necessary to provide a cooling water automatic conversion circulation device. Utility Model Content

[0004] The main purpose of the utility model is to provide an automatic conversion circulation device for cooling water, which can effectively solve the problem that the treatment of cooling water in the background technology cannot achieve the effect of automatic conversion and does not have the function of circulating cooling water, resulting in waste of water resources and consumption of energy, which is not conducive to environmental protection.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a cooling water automatic conversion circulation device, comprising a conversion box, a tank unit fixedly connected to the top of the conversion box, and a barrier unit fixedly connected between the inner walls of the tank unit, and also comprising a cooling circulation unit arranged inside the conversion box and an opening and closing unit arranged inside the barrier unit;

[0006] The cooling circulation unit comprises a cooling box installed inside the conversion box, and a circulation pump installed on the inner bottom wall of the conversion box for circulating and extracting cooling water;

[0007] The opening and closing unit includes a fixing frame movably fixedly connected to one side of the tank unit, and an opening and closing plate movably arranged inside the barrier unit for opening and closing the water flow.

[0008] Preferably, the tank unit includes a transfer tank fixedly connected to the top center of the conversion box, a water inlet pipe fixedly connected to the top of one side of the transfer tank, and a water outlet pipe fixedly connected to the top of the other side of the transfer tank.

[0009] Preferably, the barrier unit comprises a barrier platform fixedly connected between the inner walls of the transfer tank, a drainage hole penetrating through the concave center of the top of the barrier platform, and a movable groove formed on the inner wall of the drainage hole.

[0010] Preferably, the cooling circulation unit also includes a connecting pipe fixedly connected to the bottom center of the transfer tank, a disc pipe fixedly connected to one end of the connecting pipe, a cooler installed outside the disc pipe, and a circulation pipe fixedly connected to the water outlet end of the circulation pump.

[0011] Preferably, the opening and closing unit also includes a servo motor fixedly connected to one side of the fixed frame, a screw fixedly connected to the driving end of the servo motor, a threaded block threadedly connected to the outer surface of the screw, a connecting sealing plate fixedly connected to the upper and lower ends of the threaded block, and a rod hole opened at one end of the opening and closing plate.

[0012] Preferably, the coiled tube is arranged inside the cooling box, one end of the coiled tube is fixedly connected to the water inlet end of the circulation pump, and one end of the circulation tube is fixedly connected to one side of the transfer tank and communicated with the upper part of the interior of the transfer tank.

[0013] Preferably, there are two connecting sealing plates, the other ends of the two connecting sealing plates are respectively fixedly connected to the upper and lower surfaces of one end of the opening and closing plate, the inner diameter of the rod hole is larger than the outer diameter of the screw rod, and the fixing frame is fixedly connected to one side of the transfer tank.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the utility model, when hot water is lowered, it is sent into the inside of the coiled tube inside the cooling box through the connecting pipe. The arrangement of the coiled tube makes the hot water transportation process longer, so that the heat is dissipated, and then the cooler at the bottom of the coiled tube cools the water flowing in the coiled tube again. The cooled cooling water is pumped by the starting of the circulation pump and sent into the inside of the transfer tank through the circulation pipe, so as to form a circulation utilization of the cooling water. This structure can make full use of the cooling water, form automatic conversion and circulation, avoid the waste of water resources and the loss of energy, and achieve the purpose of energy saving and environmental protection.

[0016] 2. In the utility model, when the opening and closing plate is in a closed state, when the cooling water is converted into hot water after use, the hot water exists in the transfer tank above the barrier platform. When the hot water reaches a certain value, the servo motor screw is started to rotate, and the rotation of the screw drives the threaded block to move laterally on its outer surface. The lateral movement of the threaded block drives the two connected sealing plates to move synchronously, thereby pulling the opening and closing plate connected to the two connected sealing plates. As the opening and closing plate is pulled, one end of the screw enters the interior of the rod hole and the drain hole leaks out, thereby causing the hot water to fall and then be sent into the interior of the conversion box by the connecting pipe for cooling. This structure can concentrate the hot water after the cooling water is used to avoid heat loss. After full utilization, it is rotated and transported for cooling, forming an automatic conversion function for cooling water. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The cooling circulation unit 400 includes a cooling box 401 installed inside the conversion box 100 , and a circulation pump 404 installed on the inner bottom wall of the conversion box 100 for circulating and pumping cooling water.

[0035] like Figure 1 and Figure 2 As shown, the tank unit 200 includes a transfer tank 201 fixedly connected at the top center of the conversion box 100, a water inlet pipe 202 fixedly connected to the top of one side of the transfer tank 201, and a water outlet pipe 203 fixedly connected to the top of the other side of the transfer tank 201.

The barrier platform 301 is provided to facilitate the concentration of hot water after the cooling water is used, thereby facilitating the conversion between cold and hot.

[0037] like Figure 1 , Figure 2 and Figure 4As shown, the opening and closing unit 500 includes a fixing frame 501 movably fixedly connected to one side of the tank unit 200, and an opening and closing plate 506 movably arranged inside the barrier unit 300 for opening and closing the water flow.
