After the impurities are filtered out by the filter cartridge, the impurities still remain in the tank body and cannot be discharged in time. The impurities will accumulate in the tank body for a long time, reducing the storage capacity of the water in the tank body. Therefore, the cooling device of the quenching furnace is proposed to solve the above problems. UTILITY MODEL

This removes residual impurities from the water and solves the problem that some water remains in the gas discharged from the exhaust pipe, which would be wasteful if discharged directly. Also, even after the filter cartridge removes impurities, some impurities still remain in the tank and cannot be discharged in time. Over time, impurities accumulate in the tank, reducing the amount of water stored in the tank. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figs. 1 to 3 This embodiment of a cooling device for a quenching furnace includes a housing 1, a filtration device on the upper side of the housing 1, and a circulation device on the upper side of the housing 1. The filtration device includes a left-end water pump 4 fixedly installed on the upper side of the housing 1, a suction pipe 3 connected to the right side of the water pump 4, an upper first drain pipe 5 connected to the left side of the water pump 4, a lower second drain pipe 6 connected to the left side of the water pump 4, a filter box 7 connected to the lower side of the second drain pipe 6, a filter plate 8 inserted into the filter box 7, and a third drain pipe 9 connected to the lower side of the filter plate 8. The circulation device includes a right-end air pump 10 fixedly installed on the upper side of the housing 1, a cooling box 11 connected to the right side of the air pump 10, two condenser pipes 13 fixedly connected to the upper side of the cooling box 11, multiple heat absorption plates 12 inserted into the condenser pipes 13, and an oxygen barrier pipe 14 connected to the lower side of the cooling box 11.

[0025] Among them, an exhaust pump 15 is fixedly installed on the left side of the lower end of the box 1, and an aeration pipe 16 is connected to the right side of the exhaust pump 15. Multiple aeration nozzles 17 are connected to the inner side of the aeration pipe 16. The exhaust end of the exhaust pump 15 is connected to the aeration pipe 16. The upper side of the front face of the box 1 is connected to the water inlet pipe 2. The front face of the filter box 7 is hinged with a box door. The front face of the first drain pipe 5 is equipped with a first solenoid valve. The front face of the second drain pipe 6 is equipped with a second solenoid valve. The suction pipe of the air pump 10 is connected to the upper side of the box 1. The exhaust end of the air pump 10 is connected to the upper side of the cooling box 11. The condenser pipe 13 passes through the heat absorption plate 12 and the cooling box 11 and extends to its outside. The oxygen barrier pipe 14 is inserted into the inside of the box 1 on the side away from the cooling box 11. The front face of the box 1 is inlaid with a window 18.

[0026] It should be noted that the heat absorption plate 12 absorbs heat energy and transfers it to the condenser tube 13, which then converts the heat energy back into liquid and discharges it into the chamber 1, thus realizing the recycling of gas. The oxygen barrier tube 14 can effectively allow gas to enter and ensure the flow of liquid in the cooling chamber 11.

[0027] The working principle of the above embodiments is as follows:

[0028] Water inlet pipe 2 discharges water into tank 1. Exhaust pump 15 absorbs cold air and discharges it from aeration nozzle 17 inside aeration pipe 16 to the high-temperature water for cooling. Air pump 10 absorbs the hot air generated in the water and discharges it to cooling tank 11. After heat exchange through condenser pipe 13, the water is rapidly cooled and turned back into liquid. It is then discharged into tank 1 through oxygen barrier pipe 14, completing the cycle. Water pump 4 can absorb water in tank 1. If the water is used to cool the quenching furnace, the first solenoid valve on the surface of the first drain pipe 5 needs to be opened, and the second solenoid valve on the surface of the second drain pipe 6 needs to be closed to discharge the water into the quenching furnace. If the water is not used to cool the quenching furnace, the first solenoid valve is closed and the second solenoid valve is opened. The water will then be transferred to filter box 7. After the filter plate 8 filters the impurities remaining in the water, it is discharged back into tank 1 to reduce the residue of impurities in the water in tank 1.

Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply.
