[0026] Refer to Figure 1 - Figure 4The output end of the blower 9 is fixedly connected to a heater 7. By connecting the output end of the blower 9 to the heater 7, the hot air collected by the blower 9 can be heated to prevent the temperature of the hot air from decreasing. The output end of the heater 7 is fixedly connected to a delivery pipe 5. The hot air heated by the heater 7 can be transported out by setting the delivery pipe 5. The outer wall of the delivery pipe 5 is provided with an insulation block 6. The insulation block 6 is provided to reduce the contact time of the delivery pipe 5 with the outside world to prevent the internal hot air from cooling. One end of the delivery pipe 5 is fixedly connected to a filter box 2, and the exhaust gas in the hot air can be filtered through the filter box 2; the filter box 2 is fixedly connected to a first filter plate 10 near the inner wall of the insulation block 6, the second filter plate 11 is fixedly connected to the inside of the filter box 2, and the third filter plate 12 is fixedly connected to the inside of the filter box 2.

[0027] Working principle: In the heat circulation mechanism for metal heat treatment, a heat circulation process is carried out. The air inside the shell 1 is extracted by the blower 9 to form an airflow. The blower 9 transports the collected air to the heater 7. The heater 7 heats the air to increase the air temperature. The heated hot air is transmitted through the delivery pipe 5. During the transportation process, the insulation block 6 installed on the outer wall of the shell 1 can reduce the heat exchange between the delivery pipe 5 and the outside world, which can effectively prevent the hot air from cooling. When the hot air passes through the filter box 2, the first filter plate 10, the second filter plate 11 and the third filter plate 12 filter and purify the exhaust gas and other harmful substances in the hot air. The filtered hot air is then sent back to the inside of the shell 1 through the delivery pipe 5. This cycle realizes the recycling of heat within the mechanism. When installing the blower 9, by The chassis is aligned with the groove of the base 8, and the mounting sleeve 15 is placed therein. The ball 17 inside the mounting sleeve 15 is squeezed by the squeezing block 18. Since the pressure caused by the ball 17 is not enough to move the squeezing block 18, the ball 17 will be ejected from the mounting sleeve 15 and stuck in the groove inside the base 8, thereby fixing the blower 9. When the blower 9 is disassembled, the button 13 is pressed, and the button 13 drives the squeezing rod 16 to move. The squeezing rod 16 pushes the squeezing block 18 to further compress the spring 19. At this time, the ball 17 is no longer squeezed by the squeezing block 18. Under the rebound action of the spring 19, the squeezing plate 20 moves upward, driving the squeezing block 18 upward, and the ball 17 is detached from the groove of the base 8, so that the mounting sleeve 15 can be pulled out, and the blower 9 can be easily disassembled, reducing equipment downtime and improving work efficiency.
