DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figures 1 to 7 The aluminum alloy aging furnace of the utility model shown in the figure comprises a bottom plate 1, a chute is provided on the bottom plate 1, a controller 2 is installed on the bottom plate 1, an aging furnace body 3 is fixedly installed on the bottom plate 1, two cooling water tanks 4 are fixedly connected to the bottom plate 1, a water inlet is provided on the cooling water tank 4, a temperature sensor 5 is installed inside the cooling water tank 4, a first cooler 6 is fixedly installed on the cooling water tank 4, and the first cooler 6 is used to cool down the hot water, two water pumps 7 are fixedly installed on the aging furnace body 3, a first delivery pipe 8 is connected between the water pump 7 and the cooling water tank 4, a second delivery pipe 9 is connected between the water pump 7 and the aging furnace body 3, a heat exchange pipe 10 is connected inside the aging furnace body 3, and the heat exchange pipe 10 is connected to the second delivery pipe 9. A delivery pipe 9 is connected, a first electric valve 11 is installed on the second delivery pipe 9, a drain pipe 12 is connected between the heat exchange pipe 10 and the cooling water tank 4, a second electric valve 13 is installed on the drain pipe 12, an exhaust fan 14 is fixedly installed on the aging furnace body 3, the exhaust fan 14 is used to extract hot air, a heat dissipation pipe 15 is fixedly connected to the aging furnace body 3, the exhaust fan 14 is installed on the heat dissipation pipe 15, a cooling box 16 is fixedly connected to the bottom plate 1, a second cooler 17 is installed on the cooling box 16, the second cooler 17 is used to cool the cold water, an exhaust pipe 18 is fixedly connected to the aging furnace body 3, a third electric valve 19 is installed on the drain pipe 18, and a liquid level sensor 25 is installed inside the cooling water tank 4.

[0021] The controller 2 is provided with a start button.

[0022] A slide rail 20 is fixedly connected to the aging furnace body 3, two fixing frames 21 are fixedly connected to the bottom plate 1, an electric push rod 22 is fixedly installed on the fixing frame 21, a connecting rod 23 is connected to the telescopic rod of the electric push rod 22, and a closing plate 24 is connected to the connecting rod 23.

[0023] The working principle of the utility model is as follows: the liquid level sensor is provided with a first threshold value and a second threshold value, and the value of the first threshold value is smaller than the value of the second threshold value.

[0024] In the first step, when the aging furnace body is working, the electric push rod is controlled to stop working after a certain period of time, and the electric push rod drives the connecting rod and the closing plate to move inward, so that the closing plate closes the entrance of the aging furnace body to prevent excessive volatilization of heat, and then the third electric valve is controlled to open the exhaust pipe channel to prevent excessive air pressure inside the aging furnace body.

[0025] In the second step, after the aging furnace body completes its working task, the electric push rod is controlled to drive the connecting rod and the closing plate to move outward to reset, thereby opening the entrance of the aging furnace body, and at the same time controlling the third electric valve to close the exhaust pipe channel, and then injecting cold water into the cooling water tank through the water inlet. When it is necessary to cool the inside of the aging furnace body, press the start button to control the first electric valve and the water pump to work, and the first electric valve opens the second delivery pipe channel, so that the water pump extracts cold water, and the cold water enters the heat exchange tube through the first delivery pipe and the second delivery pipe, completing the heat exchange step inside the aging furnace body. When the liquid level of the cold water in the cooling water tank is lower than the first threshold preset by the liquid level sensor, the first electric valve and the water pump are controlled to stop working.

[0026] The third step is to control the second electric valve to open the drain pipe channel after the heat exchange is completed, so that the hot water in the heat exchange tube flows into the cooling water tank through the drain pipe. When the liquid level of the hot water in the cooling water tank reaches the second threshold value preset by the liquid level sensor, the second electric valve is controlled to close the drain pipe channel, and the first cooler is controlled to cool down the hot water, thereby speeding up the cooling speed of the hot water to avoid the situation where the hot water temperature is too high and heat exchange cannot be performed when the aging furnace body needs to exchange heat quickly. When the temperature of the cold water reaches the threshold value preset by the temperature sensor, the first cooler is controlled to stop working.

[0027] The fourth step is to pour cold water into the cooling box, start the vacuum pump and the second cooler. The vacuum pump extracts the hot air in the aging furnace body, so that the hot air enters the cold water in the cooling box through the heat dissipation pipe. The second cooler cools the cold water to prevent excessive hot air from increasing the temperature of the cold water, reducing the effect of cooling the hot air, and preventing the discharge of hot air from affecting the surrounding environment. After the hot air is extracted, turn off the vacuum pump and the second cooler.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
