Therefore, the present invention is not limited to the specific embodiments disclosed below.

The air inlet 3 is provided with an air cooling component on the outer end of the air inlet 3; there is a gap between the bottom surface of the other partition 2 and the inner bottom surface of the heat treatment furnace body 1, and the inner top surface of the channel formed by the partition 2 is penetrated with an exhaust hole 4 connected with the outside of the heat treatment furnace body 1, and an exhaust fan 5 with an upward wind direction is installed in the exhaust hole 4. After the workpiece is heated inside the heat treatment furnace body 1, the exhaust fan 5 is started, and the exhaust fan 5 extracts the air inside the channel formed by the partition 2 to create a negative pressure, and the partition 2 The bottom surface has a spacing gap, which is close to the workpiece, so the hot air around the workpiece enters the channel formed by the partition 2 under the attraction of negative pressure and is discharged from the heat treatment furnace body 1 by the exhaust fan 5. The space between the two partitions 2 also forms a negative pressure due to the air being sucked out. Since the top surface of the other partition 2 has a spacing gap, the channel formed by the other partition 2 is drawn air. Under the action of air pressure, the channel sucks in external air from the air inlet 3. When the external air passes through the air inlet 3, it will contact the air cooling component. The air cooling component absorbs heat and cools the external air, so that the temperature of the air entering the heat treatment furnace body 1 is lower than the room temperature. The external air flows along the channel formed by the partition 2 under the attraction of negative pressure and contacts the workpiece for heat exchange, thereby circulating and accelerating the cooling of the workpiece. The partition 2 separates the air inlet 3 and the exhaust hole 4 to form an N-shaped air duct, ensuring that the external cold air is fully in contact with the workpiece, thereby accelerating the cooling of the workpiece, and then facilitating the workers to take out the workpiece, facilitating the subsequent processing of the workpiece, and improving the efficiency of workpiece processing.

[0030] Specifically, an electric heater 13 is provided at the inner top of the heat treatment furnace body 1 between the two partitions 2, a furnace opening 14 is provided at the front end surface of the heat treatment furnace body 1 between the two partitions 2, and a sealing door 15 covering the furnace opening 14 is movably connected to the heat treatment furnace body 1.

[0031] Specifically, the outer surface of the partition 2 is a smooth plane, and the end surface is an arc surface, which is conducive to the flow of air along the channel formed by the partition 2.

[0032] Specifically, the air cooling assembly includes a water curtain mechanism and a water spray mechanism, the water curtain mechanism covers the outer port of the air inlet 3, the water spray mechanism is located on the top of the water curtain mechanism, the water curtain mechanism includes a plurality of water guide plates 6, the water guide plates 6 are stacked at intervals and cover the outer port of the air inlet 3, the shape of the water guide plates 6 is a continuous S shape and is placed vertically, the water spray mechanism includes a water tank 7, a pump body 8, a spray pipe 10 and a connecting pipe 9, the water tank 7 is located below the bottom of the water curtain mechanism, the spray pipe 10 is installed on the top of the water curtain mechanism, the pump body 8 is installed inside the water tank 7, and the connecting pipe 9 connects the pump body 8 with the spray pipe 10. The principle of the air cooling assembly is as follows: the water tank 7 of the water spray mechanism is filled with water and is transported to the spray pipe 10 by the pump body 8. The spray pipe 10 evenly sprinkles the water on the top surface of the water curtain mechanism. The water flows along the water guide plate 6 of the water curtain mechanism under the action of gravity. The continuous S-shaped water guide plate 6 significantly increases the surface area of ​​the water and prolongs the water flow time. The outside air flows from the gaps between the water guide plate 6 to the air inlet 3. The water evaporates faster under the action of the airflow, and the evaporation of water absorbs heat to reduce the temperature of the air flowing through.

[0033] Specifically, a protective shell 11 covering the air cooling assembly is disposed on the outer side of the heat treatment furnace body 1. A square opening 12 is penetrated through the outer surface of the protective shell 11 corresponding to the air inlet 3. The protective shell 11 protects the air cooling assembly and improves the neatness and beauty of the appearance.

[0034] The utility model provides a heat treatment equipment that is convenient for rapid cooling of workpieces. Its working principle is as follows: after the workpiece is heated inside the heat treatment furnace body 1, the exhaust fan 5 is started, and the exhaust fan 5 extracts the air inside the channel formed by the partition 2 to create a negative pressure. The bottom surface of the partition 2 has a gap, which is close to the workpiece, so the hot air around the workpiece enters the channel formed by the partition 2 under the suction of the negative pressure and is discharged from the heat treatment furnace body 1 by the exhaust fan 5. The space between the two partitions 2 also forms a negative pressure due to the sucked air. Since the top surface of the other partition 2 has a gap, the channel formed by the other partition 2 is drawn air. Under the action of air pressure, the channel sucks in external air from the air inlet 3. When the external air passes through the air inlet 3, it will contact the air cooling component, and the air cooling component absorbs heat and cools the external air. The principle of the air cooling component is as follows: the water tank 7 of the water spraying mechanism Water is contained inside and transported to the spray pipe 10 by the pump body 8. The spray pipe 10 evenly sprinkles the water on the top surface of the water curtain mechanism. The water flows along the water guide plate 6 of the water curtain mechanism under the action of gravity. The continuous S-shaped water guide plate 6 significantly increases the surface area of ​​the water and prolongs the water flow time. The outside air flows to the air inlet 3 from the gaps between the water guide plate 6. The water will evaporate faster under the action of the air flow, and the evaporation of water will absorb heat to reduce the temperature of the air flowing through, so that the temperature of the air entering the heat treatment furnace body 1 is lower than the room temperature. The outside air flows along the channel formed by the partition 2 under the attraction of negative pressure and contacts with the workpiece for heat exchange, thereby circulating and accelerating the cooling of the workpiece. The partition 2 separates the air inlet 3 and the air extraction hole 4 and forms an N-shaped air duct, ensuring that the outside cold air is fully in contact with the workpiece, thereby accelerating the cooling of the workpiece, and then facilitating the workers to take out the workpiece, facilitating the subsequent processing of the workpiece, and improving the efficiency of workpiece processing.
