It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0020] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0021] Embodiment 1: As Figures 1-4 shown, the present utility model provides a water cooling device for extrusion processing, including a bottom plate 1. An extruder 2 and a cooling pool 3 are respectively fixed on the top of the bottom plate 1. A heat preservation water tank 4 and a water chiller 5 are respectively arranged below the cooling pool 3. Both the heat preservation water tank 4 and the water chiller 5 are fixed on the top of the bottom plate 1. A water outlet hole 6 is opened at the bottom of the cooling pool 3. A water outlet pipe 7 communicated with the water outlet hole 6 is fixed at the bottom of the cooling pool 3. An electromagnetic valve 8 is fixed on the surface of the water outlet pipe 7. A water circulation assembly 9 is arranged on the heat preservation water tank 4 and the water chiller 5.

[0022] The overall effect achieved by the entire Embodiment 1 is that, with the cooperation of the electromagnetic valve 8 and the water circulation assembly 9, the water in the cooling pool 3, the heat preservation water tank 4, and the water chiller 5 can form a cycle. The water is repeatedly heated and cooled, so that the water in the cooling pool 3 can be maintained at a lower temperature, improving the cooling and quenching effect of the aluminum profile, and the water resources can be reasonably and effectively utilized.

[0023] Embodiment 2: As Figures 1-4 shown, a temperature sensor 10 is fixed on the top of the heat preservation water tank 4. The temperature sensing probe of the temperature sensor 10 is located inside the heat preservation water tank 4. A water level observation window 11 is arranged on one surface of the heat preservation water tank 4; the water circulation assembly 9 includes a first water pump 901 fixed on the top of the water chiller 5. The bottom end of the water outlet pipe 7 is fixedly communicated with the water inlet of the water chiller 5 by a hot water pipe 902. The water inlet of the first water pump 901 is fixedly communicated with the water outlet of the water chiller 5 by a cold water pipe 903; the water outlet of the first water pump 901 is fixedly communicated with the water inlet of the heat preservation water tank 4 by a delivery pipe 904. A second water pump 905 is fixed on the top of the heat preservation water tank 4; a connecting pipe 906 is arranged above the cooling pool 3. Both ends of the connecting pipe 906 are respectively sleeved and fixed with two brackets 907. Both brackets 907 are fixed on the top of the cooling pool 3; water discharge pipes 908 are equidistantly communicated with the surface of the connecting pipe 906. The bottom ends of the water discharge pipes 908 are all located inside the cooling pool 3; the water inlet of the second water pump 905 is fixedly communicated with the water outlet of the heat preservation water tank 4 by a water suction pipe 909. The water outlet of the second water pump 905 is fixedly communicated with one end of the connecting pipe 906 by a flexible pipe 910.

[0024] The effect achieved by the entire Embodiment 2 is that the temperature sensor 10 facilitates personnel to detect the temperature of the water in the heat preservation water tank 4, so that people can observe whether the water chiller 5 is working effectively. The water level observation window 11 enables personnel to directly determine the water storage capacity in the heat preservation water tank 4. The first water pump 901 can smoothly transport the water cooled by the water chiller 5 into the heat preservation water tank 4. The second water pump 905 can transport the low-temperature water in the heat preservation water tank 4 upward into the connecting pipe 906, so that the water discharge pipe 908 in the cooling pool 3 can smoothly discharge the low-temperature water.

[0025] Working principle: When using the extruder 2 to extrude aluminum profiles, the extruded aluminum profiles flow from the discharge port of the extruder 2 into the cooling pool 3. The cooling pool 3 is filled with cooling water, and the second water pump 905 is always in the working state. Then, the low-temperature water in the heat preservation water tank 4 can be pumped out through the water suction pipe 909, transported through the hose 910 into the connecting pipe 906. Thus, the water discharge pipes 908 can continuously discharge low-temperature water into the cooling pool 3. And the solenoid valve 8 is always in the open state. After the high-temperature aluminum profiles are quenched at low temperature, the temperature of the water in the cooling pool 3 rises. Then, the relatively high-temperature water can flow from the water outlet pipe 7 to the water chiller 5 below. The relatively high-temperature water can conduct heat exchange in the water chiller 5 and be cooled down to a suitable temperature again. The first water pump 901 can transport the water cooled again into the heat preservation water tank 4 for storage. Therefore, the water used in the water cooling process can form a cycle among the cooling pool 3, the heat preservation water tank 4, and the water chiller 5, so that the water in the cooling pool 3 can be maintained at a relatively low temperature state. The temperature sensor 10 can detect the temperature of the low-temperature water in the heat preservation water tank 4 in real time to ensure that the water in the circulation process can meet the water cooling requirements.

[0026] The wiring diagrams of the solenoid valve 8, the first water pump 901, the second water pump 905, and the temperature sensor 10 in this utility model with an external controller belong to the common knowledge in the field. Their working principles are already known technologies. Their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the solenoid valve 8, the first water pump 901, the second water pump 905, and the temperature sensor 10 will not be explained in detail. In summary, the problems raised in the above background are solved.

[0027] The above description is only a preferred embodiment of the present utility model, and it is not a limitation to the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
