[0002] The vacuum heat treatment cooling circulating water device is a system for cooling the high temperature generated during the vacuum heat treatment process. The vacuum heat treatment cooling circulating water device is widely used in industrial fields that require high-temperature cooling, such as vacuum heat treatment equipment in the petroleum, chemical, pharmaceutical, electronic, metallurgical and other industries. During the heating and insulation process of the vacuum high-pressure gas quenching furnace, the heating electrode, stirring motor, furnace door sealing ring, and hydraulic devices drawn from the furnace all need to ensure the flow of cooling water to avoid failure of the sealing device and transmission mechanical device due to excessive temperature. At this time, only cooling water needs to flow, and the water pressure and flow requirements are not large. The quenching cooling stage requires high pressure and large flow of cooling water to ensure that the heat generated in the quenching stage can be fully taken away.

[0003] The existing cooling method does not have the function of regulating pressure and flow, resulting in a generally single cooling method. As a result, the pressure and flow differences of the cooling circulating water required at different stages of the vacuum quenching furnace cannot be adjusted, which not only reduces the cooling efficiency, but also causes a waste of resources and cannot meet the process requirements.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0027] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a vacuum heat treatment cooling circulating water device, comprising a main body mechanism 1, the top of which is fixedly connected with a cooling mechanism 2;

[0028] The cooling mechanism 2 includes a cooling box 201, a semiconductor refrigerator 202 is fixedly connected to the bottom of the cooling box 201, a plurality of partitions 209 are fixedly inserted on the inner wall of the cooling box 201, a plurality of temperature detectors 203 are fixedly connected to the inner wall of the cooling box 201, a plurality of one-way valves 204 are fixedly connected to the inner wall of the cooling box 201, a pipe A205 is fixedly connected between one side of the outer walls of the plurality of one-way valves 204, an output end of the pipe A205 is fixedly connected to a multi-channel solenoid valve 206, an outer wall side of the multi-channel solenoid valve 206 is fixedly connected to a pipe B207, and an output end of the pipe B207 is fixedly connected to three pumps 208.

[0029] The effect achieved by the entire embodiment 1 is that, first, multiple one-way valves 204 can draw cooling water from the isolated space inside the cooling box 201 into itself, and then transfer it to the inside of the multi-channel solenoid valve 206, and multiple temperature detectors 203 can detect and process the water temperature inside different isolated spaces. However, when the cooling temperature is too high, the coolant inside other spaces is selected to provide sufficient time for the coolant inside the space with too high temperature to cool down. In addition, the flow and pressure used by the three pumps 208 are at different stages. The first pump 208 has a low head and flow, providing low-pressure, low-flow cooling circulating water for the heat treatment equipment. The second pump 208 has a moderate head and flow, providing medium-pressure, medium-flow cooling water for the quenching and cooling stage of the vacuum quenching furnace. The third pump 208 has a larger head and flow, providing high-pressure, large-flow cooling water for the quenching and cooling stage of the vacuum quenching furnace.

[0030] Embodiment 2, as Figure 2-Figure 4 As shown, the main mechanism 1 includes a placement plate 101, the bottom of the placement plate 101 is fixedly connected to two support plates 102, the bottoms of the two support plates 102 are fixedly connected to a group of support pads 103, the top of the placement plate 101 is fixedly connected to a vacuum high-pressure gas quenching furnace 104 near the edge, the top of the vacuum high-pressure gas quenching furnace 104 is fixedly connected to a circulation pump A105, and the output end of the circulation pump A105 is connected to the internal cooling tank of the vacuum high-pressure gas quenching furnace 104, the output end of the circulation pump A105 is fixedly connected to a cooling water delivery pipe 106, and the vacuum high-pressure gas quenching furnace 104 is fixedly connected to the cooling water delivery pipe 106. The top of the furnace 104 is fixedly connected to a quenching detector 107, and the detection end of the quenching detector 107 is connected to the interior of the vacuum high-pressure gas quenching furnace 104, the output end of the quenching detector 107 is fixedly connected to a signal control line 108, the output end of the signal control line 108 is fixedly connected to the control ends of three station pumps 208, the top of the placement plate 101 is fixedly connected to the bottom of the three station pumps 208, the top of the placement plate 101 is fixedly connected to the bottom of the cooling box 201 near the edge, and the output ends of the three station pumps 208 are all fixedly connected to the input end of the cooling water delivery pipe 106.

[0031] The effect achieved by the entire embodiment 2 is that, first, when the water is transported to the inside of the cooling water delivery pipe 106, it stays there and the flow rate and pressure are regulated therein. When the quenching detector 107 detects that cooling is required, the signal is transmitted to the inside of other components through the signal control line 108, thereby starting the circulation pump A105, keeping the cooling water inside the cooling water delivery pipe 106 instantly entering the cooling tank inside the vacuum high-pressure gas quenching furnace 104, thereby cooling the various components inside it.

[0032] The use method and working principle of the device: First, when the device is in use, multiple partitions 209 can form multiple isolated spaces inside the cooling box 201, and multiple temperature detectors 203 can detect the water temperature inside different isolated spaces. However, when the cooling temperature is too high, the coolant inside other spaces is selected to provide enough time for the coolant inside the space with too high temperature to cool down. Multiple one-way valves 204 can draw the cooling water from the isolated space inside the cooling box 201 into itself, and then pass it to the inside of the multi-channel solenoid valve 206, and then according to The quenching detector 107 detects different cooling requirements for circuit breakers and selects different pumps 208. The pump 208 then transfers the liquid inside the multi-channel solenoid valve 206 to its own interior through the pipeline B207, and then transfers the coolant to the interior of the cooling water delivery pipe 106, ensuring that the pipe diameter pressure and flow rate meet the equipment requirements when the equipment enters the quenching cooling stage. Then, when the circulating pump A105 is in the started state, it can ensure that the coolant inside the cooling water delivery pipe 106 enters the interior of the vacuum high-pressure gas quenching furnace 104, thereby effectively cooling the interior thereof.
