Description

Technical Field

[0001] This utility model relates to the field of heat treatment furnace technology, and in particular to a controlled cooling air-cooling device for a heat treatment furnace. Background Technology

[0002] Heat treatment furnaces are classified into bell-type furnaces, roller hearth furnaces, chain furnaces, traction heat treatment furnaces, and steel wire lead quenching furnaces. Heat treatment furnaces can adopt various furnace types, but require strict control of furnace temperature and atmosphere. Most heat treatment furnaces use gaseous fuel for heating. To accurately control the furnace temperature, some heat treatment furnaces use electric heating. Modern heat treatment (especially chemical heat treatment) processes are becoming increasingly complex, and there are many forms of heat treatment furnaces. It is a general term for industrial furnaces used to perform various metal heat treatments on metal workpieces.

[0003] In the prior art, a rapid cooling device for a heat treatment furnace, according to patent publication number CN220153279U, includes a base, a cooling pool fixedly connected to the inside of the base, a connecting pipe fixedly connected to the inside of the cooling pool, a water pump fixedly connected to one end of the connecting pipe, a water inlet pipe fixedly connected to the outlet of the water pump, an electric slide rail fixedly connected to the top of the base, a slider fitted inside the electric slide rail, a limit frame fixedly connected to the top of the base, and a limit block fitted inside the limit frame. This utility model can realize the raising and lowering of the spray nozzle to make the spray uniform, thereby achieving uniform cooling of the heat treatment furnace. However, for the rapid cooling of the heat treatment furnace, this device only uses water cooling and does not use an air cooling structure, which forces the rapid cooling efficiency of the heat treatment furnace to decrease. Moreover, current air cooling structures all use a single fan blade for blowing air, without setting multiple fan blades to blow air simultaneously, thus reducing the air cooling efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a controlled cooling air-cooling device for heat treatment furnaces to solve the problem of rapid cooling of heat treatment furnaces. This device only uses water cooling for cooling and does not use air cooling structure, which forces the rapid cooling efficiency of heat treatment furnaces to decrease. Moreover, the current air cooling structure uses a single fan blade for blowing air, and does not set up multiple fan blades to blow air simultaneously, which reduces the air cooling efficiency.

[0005] To achieve the above objectives, a controlled cooling air-cooling device for a heat treatment furnace is provided, comprising a heat treatment furnace body, a shell-like structure at the lower end of the outer front side of the heat treatment furnace body, and a baffle plate on its exterior. A control panel is fixed to the outer front end of the baffle plate and is electrically connected to an external power supply. A middle bottom plate is fixed to the outer bottom end of the heat treatment furnace body. An air-cooling structure is provided on the outer right side of the heat treatment furnace body, including a right bottom plate. The outer left end of the right bottom plate contacts the outer right end of the middle bottom plate. An air-cooling box is fixed to the top of the right bottom plate. A drive motor is fixed at the center of the outer right end of the air-cooling box. The output end of the drive motor extends into the air-cooling box and is fixed to a front round rod via a coupling. A fixed plate is fixed to the rear right side of the air-cooling box. A rear round rod rotates to the outer left end of the fixed plate. The front and rear round rods are connected by a conveyor belt. Air-cooling blades are fixed to the outer left ends of both the front and rear round rods.

[0006] According to the aforementioned heat treatment furnace control cooling air-cooling device, a water-cooling structure is provided on the outer left side of the main body of the heat treatment furnace. The water-cooling structure includes a left bottom plate, a water-cooling box is fixed on the top of the left bottom plate, a water inlet pipe is fixed on the outer left side of the water-cooling box, the outer right side of the water inlet pipe extends into the interior of the water-cooling box, a telescopic water pipe is fixed on the outer right end of the water-cooling box, the lower outer left end of the telescopic water pipe extends into the interior of the water-cooling box, and a spray plate is fixed on the upper outer right end of the telescopic water pipe.

[0007] According to the aforementioned heat treatment furnace control cooling air-cooling device, a telescopic air pipe is fixed on the outer left side of the air-cooling box, the lower right end of the telescopic air pipe extends into the interior of the air-cooling box, and a jet hood is fixed on the upper left side of the outer side. Both the telescopic air pipe and the telescopic water pipe include a lower pipe, and an upper pipe is embedded in the inner side of the upper end of the lower pipe.

[0008] According to the aforementioned heat treatment furnace control cooling air-cooling device, a temperature sensor is fixed on the outer left side of the heat treatment furnace body, and a temperature display screen is connected to the lower outer end of the temperature sensor.

[0010] According to the aforementioned heat treatment furnace control cooling air-cooling device, both the water-cooled box and the air-cooled box are equipped with moisture-proof features.

[0011] According to the aforementioned heat treatment furnace control cooling air-cooling device, the jet hood is arranged in an overall trapezoidal shape.

[0012] According to the heat treatment furnace control cooling air cooling device, the bottom of the middle bottom plate, the right bottom plate and the left bottom plate are all fixed with support frames.

[0013] The above solution has the following beneficial effects: When the drive motor starts, the output shaft drives the front round rod to rotate, and the air-cooling blades on the front round rod rotate synchronously, generating a high-speed airflow. The conveyor belt links with the rear round rod, causing the air-cooling blades on the rear round rod to also rotate synchronously, forming a dual-fan coordinated blower, which enhances the air pressure and air volume inside the air-cooling box. The high-pressure airflow inside the air-cooling box is delivered to the jet hood through the telescopic air pipe (composed of a lower pipe and a telescopic upper pipe). The jet hood adopts a trapezoidal flared design to expand the airflow coverage area and blow it evenly onto the outer wall of the heat treatment furnace body, accelerating heat dissipation. External water source enters the water-cooling box through the water inlet pipe to store cooling water. The interior of the water-cooling box adopts a moisture-proof design to avoid affecting the operation of the water cooling system. When the control valve on the telescopic water pipe is opened, the water flows through the telescopic water pipe (adjustable height) to the spray plate. The spray plate sprays the water evenly on the outer wall of the heat treatment furnace body, utilizing the high specific heat capacity of water to quickly absorb heat and achieve efficient cooling.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4 This utility model discloses a controlled cooling air-cooling device for a heat treatment furnace, comprising a heat treatment furnace body 1, a shell-like structure on the lower outer side of the heat treatment furnace body 1, and a baffle plate 2 on its exterior. A control panel 3 is fixed to the outer front end of the baffle plate 2 and is electrically connected to an external power supply. A middle bottom plate 4 is fixed to the outer bottom end of the heat treatment furnace body 1. An air-cooling structure is provided on the outer right side of the heat treatment furnace body 1, including a right bottom plate 5. The outer left end of the right bottom plate 5 contacts the outer right end of the middle bottom plate 4. An air-cooling box 6 is fixed to the top of the right bottom plate 5. A drive motor 7 is fixed at the center of the outer right end of the air-cooling box 6. The output end of the drive motor 7 extends into the air-cooling box 6 and is fixed to a front round rod 8 via a coupling. A fixed plate 9 is fixed to the rear right end of the air-cooling box 6. A rear round rod 10 rotates to the outer left end of the fixed plate 9. The front round rod 8 and the rear round rod 10 are connected by a conveyor belt 11. The outer left ends of both the front round rod 8 and the rear round rod 10 are fixed. The existing technology uses only water cooling for rapid cooling of heat treatment furnaces, without using an air cooling structure. This reduces the rapid cooling efficiency of the heat treatment furnace. Moreover, current air cooling structures use only one fan blade for blowing air, without multiple fan blades blowing air simultaneously, which reduces the air cooling efficiency. To address this issue, an air cooling structure can be installed on the right side of the outside of the heat treatment furnace body 1. By starting the drive motor 7, its output end rotates the front round rod 8 and the corresponding air cooling blade 12. Since the rear round rod 10 is connected to the front round rod 8 by the conveyor belt 11, the rear round rod 10 and its corresponding air cooling blade 12 are also forced to rotate around the fixed plate 9, which increases the air force inside the air cooling box 6. Finally, the air flows through the telescopic air pipe into the jet hood 17, thereby performing air cooling treatment on the outside of the heat treatment furnace body 1.

[0024] A water-cooling structure is provided on the left side of the main body 1 of the heat treatment furnace. The water-cooling structure includes a left bottom plate 13, a water-cooling box 14 is fixed on the top of the left bottom plate 13, a water inlet pipe 15 is fixed on the left side of the water-cooling box 14, and the right side of the water inlet pipe 15 extends into the interior of the water-cooling box 14. A telescopic water pipe is fixed on the right side of the water-cooling box 14, and the lower left end of the telescopic water pipe extends into the interior of the water-cooling box 14. A spray plate 16 is fixed on the upper right side of the telescopic water pipe. Water accumulates inside the water-cooling box 14 through the water inlet pipe 15. Finally, the control valve 22 on the telescopic water pipe is opened to allow the water inside the water-cooling box 14 to flow into the spray plate 16 and then be sprayed out to perform water cooling treatment on the exterior of the main body 1 of the heat treatment furnace.

[0025] A telescopic air pipe is fixed to the left side of the air-cooled box 6. The lower right end of the telescopic air pipe extends into the interior of the air-cooled box 6, and a jet hood 17 is fixed to the upper left side of the exterior. Both the telescopic air pipe and the telescopic water pipe include a lower pipe 18. An upper pipe 19 is embedded in the inner side of the upper end of the lower pipe 18. By designing the telescopic air pipe and the telescopic water pipe, it is easy to change the overall height of the jet hood 17 and the spray plate 16, so as to achieve more thorough cooling treatment of the exterior of the heat treatment furnace body 1.

[0026] A temperature sensor 20 is fixed on the left side of the exterior of the heat treatment furnace body 1. A temperature display screen 21 is connected to the lower end of the exterior of the temperature sensor 20. The temperature display screen 21 is fixedly connected to the left side of the exterior of the heat treatment furnace body 1. Through the temperature sensor 20 and the temperature display screen 21, the overall temperature of the exterior of the heat treatment furnace body 1 can be sensed in a timely manner.

[0027] Control valves 22 are installed on the top side of the telescopic water pipe, the water inlet pipe 15, and the telescopic air pipe to facilitate the control of water and air flow. The water-cooled box 14 and the air-cooled box 6 are both moisture-proof to avoid affecting the water-cooling and air-cooling treatment effects.

[0028] The jet hood 17 is designed in a trapezoidal shape to expand the spray area of ​​the airflow. The bottom of the middle bottom plate 4, the right bottom plate 5 and the left bottom plate 13 are all fixed with support frames 23 to stabilize the heat treatment furnace body 1, the air-cooled box 6 and the water-cooled box 14, thereby improving the stability of the three.

[0029] Working principle: First, for the air-cooled system, the drive motor 7 starts, and the output shaft drives the front round rod 8 to rotate. The air-cooling blades 12 on the front round rod 8 rotate synchronously, generating a high-speed airflow. The conveyor belt 11 is linked to the rear round rod 10, causing the air-cooling blades 12 on the rear round rod 10 to also rotate synchronously, forming a dual-fan coordinated blower, which enhances the air pressure and air volume inside the air-cooled box 6. The high-pressure airflow inside the air-cooled box 6 is delivered to the jet hood 17 through the telescopic air pipe (composed of the lower pipe 18 and the telescopic upper pipe 19). The jet hood 17 adopts a trapezoidal flared design to expand the airflow coverage area and blow it evenly onto the outer wall of the heat treatment furnace body 1 to accelerate heat dissipation. The control valve 22 can adjust the airflow size to adapt to different cooling requirements. For the water-cooled system, the external water source enters the water-cooled box 14 through the water inlet pipe 15 to store cooling water. The interior of the water-cooled box 14 adopts a moisture-proof design to avoid affecting the cooling system. When the water cooling system is in operation, the control valve 22 on the telescopic water pipe is opened, and water flows through the telescopic water pipe (adjustable height) to the spray plate 16. The spray plate 16 sprays water evenly on the outer wall of the heat treatment furnace body 1, utilizing the high specific heat capacity of water to quickly absorb heat and achieve efficient cooling. Then, the temperature sensor 20 monitors the furnace body temperature in real time and feeds back the data through the temperature display screen 21. The system can automatically or manually select the air cooling mode, water cooling mode, or mixed mode to achieve the optimal cooling strategy. When the temperature is high, air cooling is activated first. If the cooling rate is insufficient, water cooling is activated to avoid wasting water resources. The telescopic air pipe and telescopic water pipe both adopt a nested structure of lower pipe 18 + upper pipe 19. The height of the air jet hood 17 and the spray plate 16 can be manually or automatically adjusted to ensure that the airflow / water flow covers the furnace body surface at different locations, improving the cooling uniformity and thus completing the overall operation.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
