[0025] During the process of continuous generation of flue gas in the tempering furnace 11, in order to reduce excessive loss of flue gas and heat, the flow control valve 16 will only maintain a small opening. At this time, the explosion-proof valve 13 can prevent the air pressure in the working chamber from being too high, and evacuate the excessive air pressure in time to improve safety. Subsequently, the heat exchange mechanism 2 and the water delivery mechanism 3 cooperate with each other to utilize the flue gas and heat the cold water.

[0026] like Figure 2 , Figure 3 As shown, the left part of the top of the heat exchanger 21 is fixedly connected to the motor 23, the output end of the motor 23 is fixedly connected to the rotating rod 24, the outer wall of the rotating rod 24 is rotatably connected to the top of the heat exchanger 21, the top of the rotating rod 24 is rotatably connected to the sealing ring 211, the outer wall of the sealing ring 211 is fixedly connected to the top of the heat exchanger 21, the bottom end of the rotating rod 24 is fixedly connected to the active bevel gear 25, the outer wall of the active bevel gear 25 is meshed with the driven bevel gear 26, the axis of the driven bevel gear 26 is fixedly connected to the rotating shaft 27, the left end of the rotating shaft 27 is rotatably connected to the top of the inner cavity of the heat exchanger 21, the outer wall of the rotating shaft 27 is rotatably connected to the connecting block 212, and the top of the connecting block 212 is fixedly connected to the top of the inner cavity of the heat exchanger 21.

[0027] By starting the motor 23, the motor 23 drives the rotating rod 24 to rotate, so that the rotating rod 24 drives the active bevel gear 25 to mesh with the driven bevel gear 1 26, and the driven bevel gear 1 26 drives the rotating shaft 27 to rotate.

[0028] like Figure 2 , Figure 4 As shown, the right part of the rotating shaft 27 is fixedly connected with the driven bevel gear 28, the bottom of the driven bevel gear 28 is meshed with the driven bevel gear 3 29, the axis of the driven bevel gear 3 29 is fixedly connected with a rotating block 291, the bottom end of the rotating block 291 is rotatably connected with the guide net 213, the outer wall of the guide net 213 is fixedly connected to the top of the inner cavity of the heat exchanger 21, the bottom of the rotating block 291 is fixedly connected with a brush rod 292, the bottom end of the brush rod 292 is slidably connected to the top of the guide net 213, one end of the brush rod 292 is fixedly connected with a guide block 293, and the outer wall of the guide block 293 is slidably connected to the top of the heat exchanger 21.

[0029] When the rotating shaft 27 rotates, it drives the driven bevel gear 28 to mesh with the driven bevel gear 3 29, and the driven bevel gear 3 29 drives the rotating block 291 to rotate synchronously, and the rotating block 291 drives the brush rod 292 to rotate synchronously, and the brush rod 292 drives the guide block 293 to rotate synchronously, and the guide block 293 guides the brush rod 292, so that the brush rod 292 rotates more smoothly, thereby allowing the brush rod 292 to clean the guide net 213 to prevent the guide net 213 from being blocked, thereby achieving a cleaning effect.

[0030] like Figure 2 , Figure 5 As shown, a water inlet 32 ​​is fixedly connected to the front portion of the top of the water tank 31, a filter screen 33 is fixedly connected to the top of the inner cavity of the water tank 31, a water pump 34 is fixedly connected to the middle portion of the top of the water tank 31, and water pipes 35 are fixedly connected to the output and input ends of the water pump 34. The outer wall of the water pipe 35 at the input end is fixedly connected to the inner wall of the filter screen 33, the outer wall of the water pipe 35 at the output end is fixedly connected to the bottom of the heat exchanger 21, and a spiral water pipe 36 is fixedly connected to the left end of the water pipe 35 at the output end, and the outer wall of the spiral water pipe 36 is fixedly connected to the inner wall of the heat exchanger 21.

[0031] When the water in the water tank 31 is insufficient, water is added into the water tank 31 through the water inlet 32, and the water flows through the filter 33 to filter out impurities in the water, thereby preventing the subsequent spiral water pipe 36 from being blocked, thereby achieving the effect of preventing blockage.

[0032] like Figure 2 , Figure 5 As shown, the outer wall of the top of the spiral water pipe 36 penetrates through the outer wall of the heat exchanger 21 and is fixedly connected to a water temperature sensor 37 , and the top of the spiral water pipe 36 is fixedly connected to a heating pipe 38 .

[0033] When the water pipe 35 draws out the cooling water in the water tank 31 and transports it to the spiral water pipe 36, the cooling water in the spiral water pipe 36 exchanges heat with the flue gas, and the cooling water in the spiral water pipe 36 is heated. The heated water is discharged from the spiral water pipe 36. When being discharged, the water temperature is monitored by the water temperature sensor 37. If the water temperature is not high enough, the heating pipe 38 is started to heat the water to meet the water temperature standard.

[0034] The working principle of the utility model is as follows: when in use, the tempering furnace 11 works to continuously generate flue gas, and then the vacuum pump 17 is started, and the flue gas in the tempering furnace 11 is extracted by the vacuum pump 17 through the gas pipe 15 and discharged into the heat exchanger 21. When the flue gas enters the heat exchanger 21 through the gas pipe 15, the temperature sensor 14 monitors the temperature of the flue gas in the tempering furnace 11. When the temperature does not reach the process requirement, the flow control valve 16 will only transport a part of the flue gas in the tempering furnace 11, which has the effect of controlling the flow rate. The flue gas entering the heat exchanger 21 is guided through the guide net 213 and flows downward. At the same time, the motor 23 is started, and the motor 23 drives the rotating rod 24 to rotate, so that the rotating rod 24 drives the active bevel gear 25 to mesh with the driven bevel gear 1 26, and the driven bevel gear 1 26 drives the rotating shaft 27 to rotate, and the rotating shaft 27 drives the driven bevel gear 28 to mesh with the driven bevel gear 3 29, and the driven bevel gear 3 29 drives the rotating block 291 to rotate synchronously, and the rotating block 291 drives the brush rod 292 to rotate synchronously, and the brush rod 292 drives the guide block 293 to rotate synchronously, and the guide block 293 guides the brush rod 292, so that the brush rod 292 rotates more smoothly, thereby allowing the brush rod 292 to clean the guide net 213 to prevent the guide net from being damaged. The net 213 is blocked, which has a cleaning effect. After that, the water pump 34 is started, and the cooling water in the water tank 31 is pumped out by the water pipe 35 and transported to the spiral water pipe 36, so that the cooling water in the spiral water pipe 36 exchanges heat with the flue gas, and the cooling water in the spiral water pipe 36 is heated. The heated water is discharged from the spiral water pipe 36. When discharged, the water temperature is monitored by the water temperature sensor 37. If the water temperature is not enough, the heating pipe 38 is started to heat the water to make the water temperature meet the standard. In this process, the flue gas in the heat exchanger 21 is output by the vacuum pump 17 and discharged to the outside. When the flue gas is discharged, it is filtered by the smoke filter 18. , to treat the flue gas and prevent it from polluting the atmosphere. Later, when the water in the water tank 31 is insufficient, water is added to the water tank 31 through the water inlet 32, and the water flows through the filter 33 to filter out impurities in the water, thereby preventing the subsequent spiral water pipe 36 from being blocked, thereby preventing blockage. Later, when the temperature in the tempering furnace 11 reaches the process requirements, the temperature sensor 14 will control the flow control valve 16 to increase the opening, thereby increasing the flue gas delivery rate without losing the heating temperature in the tempering furnace 11, and using the flue gas to heat the cold water to improve the utilization of the flue gas, thereby greatly improving the user experience.
