[0002] The temperature control measures for concrete have always been a major technical problem in summer construction, especially the temperature control for dam concrete pouring is more stringent. The pouring of dam concrete is a key process in water conservancy project construction.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. The ice storage coil mechanism uses the evaporation of liquid refrigerant to store ice and form an ice layer, so that the normal temperature water flowing through the ice layer can be cooled into the required mixing water. The refrigerant circulation mechanism provides liquid refrigerant to the ice storage coil mechanism. The refrigerant circulation mechanism can convert the gaseous refrigerant into liquid refrigerant by means of cooling water. The cooling water circulation mechanism cools the heated cooling water. In this way, the ice storage coil mechanism, the refrigerant circulation mechanism, and the cooling water circulation mechanism cooperate to form a cooling system, which can quickly cool the normal temperature water.

[0025] Combined with Figure 1 As shown, this embodiment is a cooling device for the water used in concrete mixing, including an ice storage coil mechanism, a refrigerant circulation mechanism, and a cooling water circulation mechanism. The ice storage coil mechanism can use the refrigerant to store ice to form an ice layer, so that the normal temperature water flowing through the ice layer is cooled into the mixing water that meets the requirements. The refrigerant circulation mechanism is connected to the ice storage coil mechanism through the first circulation pipeline. The ice storage coil mechanism stores ice by evaporating the liquid refrigerant during the ice storage process, and the refrigerant circulation mechanism can convert the gaseous refrigerant into a liquid refrigerant with the help of the cooling water and circulate and supply the liquid refrigerant to the ice storage coil mechanism. The cooling water circulation mechanism is connected to the refrigerant circulation mechanism through the second circulation pipeline. The refrigerant circulation mechanism absorbs heat from the cooling water, and the cooling water circulation mechanism can cool the heated cooling water and circulate and supply the cooled cooling water to the refrigerant circulation mechanism.

[0026] In some embodiments, the ice storage coil mechanism includes a direct expansion ice storage coil group 10, an external melt ice thermal storage tank 12, a chilled water transfer pump 14, and a chilled water outlet pipe 15. The direct expansion ice storage coil group 10 is placed in the first chamber of the external melt ice thermal storage tank 12, and the direct expansion ice storage coil group 10 is connected to the refrigerant circulation mechanism through a first circulation pipeline. The water inlet of the external melt ice thermal storage tank 12 is provided with a water inlet 6 for inputting normal temperature water. The inner wall of the external melt ice thermal storage tank 12 is provided with a water supply distributor 9 communicating with the water inlet 6. The water outlet end of the external melt ice thermal storage tank 12 is connected to a chilled water outlet pipe 15 through the chilled water transfer pump 14. In this embodiment, the direct expansion ice storage coil group 10 is made of aluminum alloy material and is of direct cooling type.

[0027] Further, a vertical stirrer 13 is provided in the second chamber of the external melt ice thermal storage tank 12. The inner wall of the second chamber is provided with a water outlet distributor 11 communicating with the first chamber. The outer wall of the second chamber is communicated with the water outlet end of the external melt ice thermal storage tank 12.

[0028] Further, an automatic make-up water valve 7 for adjusting the flow rate of the water inlet 6 is provided on the external melt ice thermal storage tank 12.

[0029] Further, a sight glass 8 is provided on the external melt ice thermal storage tank 12.

[0030] In some embodiments, the refrigeration cycle mechanism includes a water-cooled screw condensing compressor unit 3. The first circulation pipeline includes a refrigerant supply pipe 5 and a refrigerant return pipe 4. The water-cooled screw condensing compressor unit 3 is connected to the cooling water circulation mechanism through a second circulation pipeline. The water-cooled screw condensing compressor unit 3 is connected to the direct expansion ice storage coil group 10 through the refrigerant supply pipe 5 and the refrigerant return pipe 4. The water-cooled screw condensing compressor unit 3 uses cooling water as a medium to transfer the heat of the refrigerant to the cooling water, thereby realizing the condensation process of the refrigerant.

[0031] In some embodiments, the cooling water circulation mechanism includes a cooling water tower 1. The second circulation pipeline includes a cooling water pipe and a cooling water circulation pump 2. The cooling water tower 1 is connected to the water-cooled screw condensing compressor unit 3 through the cooling water pipe, and the cooling water circulation pump 2 is installed on the cooling water pipe. The cooling water tower 1 can cool and dissipate the heat of the cooling water flowing through the water-cooled screw condensing compressor unit 3 and then return the cooled cooling water to the water-cooled screw condensing compressor unit 3.

[0032] The implementation principle of an embodiment of a cooling device for concrete mixing water is as follows:

[0033] In use, connect normal temperature water to the water inlet 6, and use the automatic water replenishing valve 7 to control the water inflow. The normal temperature water enters the external melt ice thermal energy storage tank 12 through the water supply distributor 9. A direct expansion ice storage coil group 10 is arranged in the first chamber of the external melt ice thermal energy storage tank 12. The water-cooled screw condensing compressor unit 3 flows liquid refrigerant into the aluminum alloy coils of the direct expansion ice storage coil group 10. The evaporation of the liquid refrigerant causes an ice layer to form on the outer surface of the aluminum alloy coils. The normal temperature water flowing into the external melt ice thermal energy storage tank 12 is in direct contact with the ice layer, with good heat exchange effect and fast heat release, facilitating the direct expansion ice storage coil group 10 to convert the incoming normal temperature water into cold water.

[0034] Meanwhile, the cold water flows into the second chamber of the external melt ice thermal energy storage tank 12 through the water outlet distributor 11. A vertical stirrer 13 is arranged in the second chamber, and the vertical stirrer 13 is used to assist in improving the heat exchange efficiency of the aluminum alloy coils in the direct expansion ice storage coil group 10. The converted cold water enters the cold water outlet pipe 15 through the cold water pump 14, and the water flowing out through the cold water outlet pipe 15 can be used as concrete mixing water.

[0035] This device forms a cooling system by combining the "cooling tower 1, water-cooled screw condensing compressor unit 3, and direct expansion ice storage coil group 10" in a combined manner. First, make the required cooling capacity into an ice-water mixture, store the cooling capacity by making ice, and form an ice layer outside the coils, so as to quickly convert normal temperature water into mixing water at 0°C - 1°C, solving the problems of complex process, long time, and poor refrigeration effect existing in conventional direct ice addition.

[0036] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
