[0004] The utility model provides a technical solution for solving the above technical problems: a deep-well furnace oil tank rapid cooling device, comprising an oil tank, a water jacket wrapped around the outside of the oil tank, water in the water jacket and oil in the oil tank performing heat exchange through the oil tank wall, water in the water jacket being collected into the water tank by a self-priming pump, water in the water tank flowing into the water jacket through a pipe, and water circulation between the water jacket and the water tank.

[0005] The above-mentioned deep well furnace oil tank rapid cooling device also includes a chiller, which is connected to the water tank to form a circulation, and the temperature of the water in the water tank is controlled by the chiller.

[0006] The above-mentioned deep-well furnace oil tank rapid cooling device also includes a blower, which is connected to the oil tank through a pipeline, and nitrogen is introduced into the oil tank through the blower.

[0007] The beneficial effects of the utility model are: the utility model realizes high-speed cooling through external water circulation heat exchange cooling and internal blast heat loss, and solves the problem of overheating of oil temperature in continuous quenching oil tank of deep well furnace; and the utility model is easy to operate, and the cooling process can be automatically completed by a one-button start device, which reduces the difficulty of operation and labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a schematic diagram of the overall structure of the utility model. DETAILED DESCRIPTION

[0009] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0010] like Figure 1As shown, a deep-well furnace oil tank rapid cooling device includes an oil tank 1, a chiller 7, and a blower 4. The oil tank 1 is wrapped with a water jacket 2.
