Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology, specifically to an air regulating device for metal heat treatment equipment. Background Technology

[0002] Metal heat treatment equipment is used to heat, cool, and hold metal materials to change their microstructure and properties. In metal heat treatment equipment, the air regulating device is mainly used to control the atmosphere and temperature distribution in the furnace. For combustion heating equipment, a reasonable air supply can ensure that the fuel is fully combusted. In some atmosphere furnaces, the air regulating device can also regulate the flow of the protective atmosphere to ensure that the metal workpiece is not oxidized or decarburized during the heat treatment process.

[0003] CN216274244U discloses an air regulating device for metal heat treatment equipment, relating to the field of metal heat treatment technology. This air regulating device includes a fan body. A groove penetrating the surface of the fan body is formed on its upper surface. A sliding plate is slidably connected to the inner wall of the groove. Extrusion grooves are formed on both the front and rear sides of the sliding plate. The bottoms of two extrusion grooves on the surface of the sliding plate are interconnected and penetrate the surface of the sliding plate. An air regulating mechanism is installed inside the two extrusion grooves. By setting up the air regulating mechanism, the device can adjust the area of ​​airflow according to the size of the metal workpiece, avoiding the situation where the airflow above the fan body is useless due to a small metal workpiece, thus preventing the waste of airflow. Simultaneously, it can concentrate the airflow for air cooling of the metal workpiece, accelerating the cooling time, improving the cooling efficiency of the device, and enhancing its practicality.

[0004] While the existing technology CN216274244U has many advantages in use, it still has the following problems: its air volume regulation is not perfect; its large-size adjustment method causes airflow to collide with the baffles, which directly causes wind noise when the gas flows inside the pipe; and dust particles mixed in the gas will adhere to the ventilation holes, and the clumps of dust particles will eventually affect the airflow.

[0005] To address the problems in the existing technology, this utility model provides an air regulating device for metal heat treatment equipment.

[0006] The technical solution adopted by this utility model to solve its technical problem is an air regulating device for metal heat treatment equipment, including an air supply box, a partition plate, and a baffle plate. An air supply baffle plate is provided on one outer wall of the air supply box, an air supply pipe is provided on one inner wall of the air supply box, a partition plate is installed on one inner wall of the air supply pipe, a linkage shaft is rotatably installed on one inner wall of the partition plate, a baffle plate is installed on the outer wall of one end of the linkage shaft, a first ventilation hole with a circular array is opened inside the partition plate, a second ventilation hole is opened inside the baffle plate, a dust suction pipe is provided on one inner wall of the second ventilation hole, a connecting pipe is screwed to one outer wall of one side of the baffle plate, and a rubber hose is inserted and installed on one outer wall of the upper end of the connecting pipe.

[0007] By adopting the above technical solution, the air supply box provides a relatively enclosed space in the overall device, ensuring that the air delivery and regulation process takes place in a stable environment, and ensuring the easy installation of the air supply duct and air supply baffle. The partition plate can divide the interior of the air supply duct, allowing the airflow inside the air supply duct to flow in a controlled manner between the first ventilation hole and the second ventilation hole. Through the cooperation of the baffle plate and the partition plate, the ventilation volume can be precisely controlled by adjusting the overlap area between the baffle plate and the first ventilation hole. The suction pipe can extend into the first ventilation hole to extract and collect the dust and impurities adhering to the inner wall of the first ventilation hole, reducing the dust and impurities stored in the inner wall of the first ventilation hole and ensuring the airflow inside the first ventilation hole. Through the flexibility and sealing of the rubber hose, the connecting pipe and the external pipe can be flexibly connected, ensuring that the dust and impurities extracted by the suction pipe can be discharged through the connecting pipe, rubber hose and external pipe, ensuring the smooth discharge of dust and impurities and preventing the accumulation of dust and impurities inside the first ventilation hole.

[0008] Specifically, a fan body is provided on one side of the outer wall of the air supply baffle, and a filter screen is provided on one side of the outer wall of the air supply baffle.

[0009] By adopting the above technical solution, sufficient airflow can be generated to deliver external air into the air supply pipe, and the air supply pipe can deliver external air into the connecting equipment, providing a stable air supply for the metal heat treatment equipment. In addition, the filter screen can effectively filter out large particulate impurities in the air, preventing these impurities from entering the metal heat treatment equipment.

[0010] Specifically, the air supply pipe is equipped with fasteners on both sides of the lower outer wall, and the air supply pipe is connected to the lower inner wall of the air supply box through the fasteners. A flange is welded to one end of the air supply pipe that passes through the outer wall of the air supply box.

[0011] By adopting the above technical solution, the fasteners ensure that the air supply duct is firmly installed inside the air supply box, which enhances the stability of the air supply duct and prevents displacement or damage due to vibration or other external forces during operation. This ensures the stable delivery of airflow in the air supply duct, and the flange facilitates the connection of the air supply duct with other equipment or pipelines, providing a reliable and robust connection method to ensure the airtightness and continuity of airflow.

[0012] Specifically, a sealing ring is fixed to the outer wall of one end of the air supply pipe, and the sealing ring is in contact with the outer wall of the air supply baffle.

[0013] By adopting the above technical solution, the sealing ring can effectively prevent gas leakage between the air supply pipe and the air supply baffle. While ensuring the air pressure in the air supply pipe, it avoids air volume loss and efficiency reduction caused by air leakage, improves the working efficiency and performance of the air conditioning device, and ensures that air can be accurately delivered along the predetermined path, making the air conditioning effect more precise and stable.

[0014] Specifically, one end of the suction pipe protrudes from the second ventilation hole and is located inside the first ventilation hole, and the connecting pipe is connected to the suction pipe.

[0015] By adopting the above technical solution, the suction pipe can move inside the first ventilation hole according to the rotation of the baffle plate, ensuring the completeness of the suction pipe to the inside of the first ventilation hole, thereby ensuring the thoroughness of the suction of dust and impurities on the inner wall of the first ventilation hole, ensuring the smooth flow of air inside the first ventilation hole, and ensuring the airflow volume.

[0016] Specifically, an external connecting pipe is inserted and installed on one side of the upper outer wall of the air supply pipe. The upper end of the external connecting pipe protrudes from the upper end of the air supply box, and the lower outer wall of the external connecting pipe is connected to a rubber hose.

[0017] By adopting the above technical solution, the external pipe is connected to an external vacuuming device, thereby enabling the vacuuming of the inner wall of the first ventilation hole through the rubber hose, connecting pipe and vacuuming pipe.

[0018] Specifically, both sides of the inner walls of the first and second ventilation holes are designed with an arc shape, and the sizes of the first and second ventilation holes are matched.

[0019] By adopting the above technical solution, the arc-shaped design helps to reduce the resistance when the airflow passes through, allowing the airflow to pass through the ventilation holes more smoothly. Furthermore, the multi-channel diversion of the first and second ventilation holes reduces the noise of airflow, ensuring the stability and smooth operation of the equipment. Moreover, by precisely adjusting the angle of the baffle, the opening degree between the first and second ventilation holes can be adjusted, achieving fine adjustment of the air volume and meeting the precise air volume requirements of metal heat treatment equipment at different process stages.

[0020] Specifically, a drive motor is provided on the outer wall of one end of the linkage shaft, and the drive motor is connected to the outer wall of the partition plate.

[0021] By adopting the above technical solution, the drive motor provides power support for the rotation of the wind deflector, and the rotation angle of the wind deflector can be precisely controlled by the drive motor to realize the automatic adjustment of the air volume.

[0032] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0033] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the air regulating device of the metal heat treatment equipment of this utility model includes an air supply box 1, a partition plate 2, and a baffle plate 3. An air supply baffle 11 is provided on one outer wall of the air supply box 1, an air supply pipe 13 is provided on one inner wall of the air supply box 1, a partition plate 2 is installed on one inner wall of the air supply pipe 13, a linkage shaft 22 is rotatably installed on one inner wall of the partition plate 2, a baffle plate 3 is installed on the outer wall of one end of the linkage shaft 22, a first ventilation hole 21 is opened in a circular array inside the partition plate 2, a second ventilation hole 31 is opened inside the baffle plate 3, a dust suction pipe 32 is provided on one inner wall of the second ventilation hole 31, a connecting pipe 33 is screwed to one outer wall of one side of the baffle plate 3, and a rubber hose 34 is inserted and installed on one outer wall of the upper end of the connecting pipe 33.

[0034] In use, the air supply box 1 provides a relatively enclosed space within the overall device, ensuring that the air delivery and regulation process takes place in a stable environment and facilitating the installation of the air supply duct 13 and the air supply baffle 11. The partition plate 2 divides the interior of the air supply duct 13, allowing the airflow inside the duct 13 to flow in a controlled manner between the first ventilation hole 21 and the second ventilation hole 31. Furthermore, through the cooperation of the baffle plate 3 and the partition plate 2, the ventilation volume can be precisely controlled by adjusting the overlap area between the baffle plate 3 and the first ventilation hole 21, thereby improving dust collection efficiency. The tube 32 can extend into the first ventilation hole 21 to extract and collect dust and impurities adhering to the inner wall of the first ventilation hole 21, reducing the amount of dust and impurities on the inner wall of the first ventilation hole 21 and ensuring the airflow inside the first ventilation hole 21. Through the flexibility and sealing of the rubber hose 34, it can flexibly connect the connecting tube 33 and the outer tube 15, ensuring that the dust and impurities extracted by the suction tube 32 can be discharged through the connecting tube 33, the rubber hose 34 and the outer tube 15, ensuring the smooth discharge of dust and impurities and preventing the accumulation of dust and impurities inside the first ventilation hole 21.

[0035] To drive airflow, for example, such as Figure 2 As shown, a fan body 12 is provided on one side of the outer wall of the air supply baffle 11, and a filter screen is provided on one side of the outer wall of the air supply baffle 11.

[0036] During use, it can generate sufficient airflow to deliver external air to the air supply duct 13, and through the air supply duct 13, it can deliver external air into the connected equipment, providing a stable air supply for the metal heat treatment equipment. The filter screen can effectively filter out large particulate impurities in the air, preventing these impurities from entering the metal heat treatment equipment.

[0037] To connect to external devices, for example, such as Figure 2 As shown, fasteners 16 are installed on both sides of the lower outer wall of the air supply pipe 13. The air supply pipe 13 is connected to the lower end of the inner wall of the air supply box 1 through the fasteners 16. A flange 14 is welded to one end of the outer wall of the air supply box 1 through the air supply pipe 13.

[0038] During use, the fastener 16 ensures that the air supply pipe 13 is firmly installed inside the air supply box 1, which enhances the stability of the air supply pipe 13 and prevents displacement or damage due to vibration or other external forces during operation. This ensures the stable delivery of airflow within the air supply pipe 13. Furthermore, the flange 14 facilitates the connection of the air supply pipe 13 with other equipment or pipelines, providing a reliable and robust connection method that ensures the airtightness and continuity of the airflow.

[0039] For sealing, exemplarily, such as Figure 2 As shown, a sealing ring is fixed to the outer wall of one end of the air supply duct 13, and the sealing ring is in contact with the outer wall of the air supply baffle 11.

[0040] During use, the sealing ring can effectively prevent gas leakage between the air supply pipe 13 and the air supply baffle 11. While ensuring the air pressure in the air supply pipe 13, it avoids air volume loss and efficiency reduction caused by air leakage, improves the working efficiency and performance of the air conditioning device, and ensures that the air can be accurately delivered along the predetermined path, making the air conditioning effect more precise and stable.

[0041] For vacuuming, for example, such as Figure 3 As shown, one end of the suction pipe 32 protrudes from the second ventilation hole 31 and is located inside the first ventilation hole 21, and the connecting pipe 33 is connected to the suction pipe 32.

[0042] When in use, the suction pipe 32 can move inside the first ventilation hole 21 according to the rotation of the baffle plate 3, ensuring the completeness of the suction pipe 32 to the inside of the first ventilation hole 21, thereby ensuring the thorough suction of dust and impurities on the inner wall of the first ventilation hole 21, ensuring the smooth flow of air inside the first ventilation hole 21, and ensuring the airflow volume.

[0043] For vacuuming, for example, such as Figure 5 As shown, an external pipe 15 is inserted and installed on one side of the upper outer wall of the air supply pipe 13. The upper end of the external pipe 15 protrudes from the upper end of the air supply box 1, and the lower outer wall of the external pipe 15 is connected to the rubber hose 34.

[0044] In use, the external tube 15 is connected to an external vacuum cleaner, so that the inner wall of the first ventilation hole 21 can be vacuumed through the rubber hose 34, the connecting tube 33 and the vacuum tube 32.

[0045] For example, to adjust the airflow, such as... Figure 3 As shown, both sides of the inner walls of the first ventilation hole 21 and the second ventilation hole 31 are designed with an arc shape, and the sizes of the first ventilation hole 21 and the second ventilation hole 31 are matched.

[0046] In use, the arc-shaped design helps to reduce airflow resistance, allowing airflow to pass through the ventilation holes more smoothly. The multi-channel diversion of the first ventilation hole 21 and the second ventilation hole 31 reduces the noise of airflow, ensuring stable and smooth operation of the equipment. Furthermore, by precisely adjusting the angle of the baffle plate 3, the opening degree between the first ventilation hole 21 and the second ventilation hole 31 can be adjusted, achieving fine adjustment of the air volume and meeting the precise air volume requirements of metal heat treatment equipment at different process stages.

[0047] To drive rotation, for example, such as Figure 3 As shown, a drive motor 23 is provided on the outer wall of one end of the linkage shaft 22, and the drive motor 23 is connected to the outer wall of the partition plate 2.

[0048] In use, the drive motor 23 provides power support for the rotation of the baffle 3, and the rotation angle of the baffle 3 can be precisely controlled by the drive motor 23 to realize the automatic adjustment of the air volume.

[0049] In use, the airflow generated by the blower body 12 enters the air supply pipe 13 through the air supply baffle 11 and is prevented from leaking gas by the sealing ring. The airflow flows along the air supply pipe 13 and encounters the first ventilation holes 21 distributed in a circular array at the partition plate 2. These first ventilation holes 21 initially distribute the airflow evenly, causing the airflow to begin to disperse and form a relatively stable and orderly flow state. Then the airflow passes through the second ventilation hole 31 and is transported through the air supply pipe 13 to ensure that the airflow can be smoothly transported to the metal heat treatment equipment.

[0050] Start the drive motor 23, which drives the linkage shaft 22 to rotate, thereby rotating the baffle plate 3. The second ventilation hole 31 on the baffle plate 3 overlaps to a certain extent with the first ventilation hole 21 on the partition plate 2. By adjusting the rotation angle of the baffle plate 3, the overlapping area of ​​the second ventilation hole 31 and the first ventilation hole 21 can be changed, thereby precisely controlling the ventilation volume. When the baffle plate 3 rotates to the point where the second ventilation hole 31 and the first ventilation hole 21 completely overlap, the ventilation volume is at its maximum; while when the baffle plate 3 rotates to the point where the second ventilation hole 31 and the first ventilation hole 21 almost do not overlap, the ventilation volume is at its minimum.

[0051] During subsequent cleaning, the blower body 12 stops, and the baffle plate 3 is driven to rotate. The suction pipe 32 and the external vacuum cleaner then come into play. The suction pipe 32 can extract and collect dust and impurities on the inner wall of the first ventilation hole 21. The collected dust and impurities are discharged into the external vacuum cleaner through the connecting pipe 33, the rubber hose 34, and the external connecting pipe 15.

The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
