Description
Technical Field
[0001] The utility model relates to the technical field of exhaust, in particular to an exhaust hood with a wind direction regulating function. Background Art
[0002] In the process of producing the rolls, a series of tests were conducted to make the rolls after heat treatment form a uniform martensitic transformation. Based on the test data, a set of rolling air-cooled rolling brackets was designed. A set of transmission motors outside the bracket can drive the rotation of the bracket rollers, and the strong wind can be used to transform the metal material, reducing a series of problems such as uneven material hardness caused by uneven transformation.
[0003] A fan is a mechanical device used to transport gas. It generates airflow through rotating blades or impellers driven by a motor, thereby achieving gas circulation and pressure increase. The airflow passes through the exhaust hood and blows to the rollers to achieve the transformation of the metal material of the rollers. However, no matter how much air volume the fans purchased on the market have, the wind force is not concentrated and the wind direction range cannot be controlled. These problems are uncontrollable in the air cooling of heat treatment, making it difficult to control the material transformation of the metal after heat treatment.
[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0023] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.
[0024] According to an embodiment of the utility model, an exhaust hood with a wind direction adjustment function is provided.
[0025] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4As shown, the exhaust hood with wind direction adjustment function according to the embodiment of the utility model comprises a fan 1, an exhaust compression section 2 is arranged at the exhaust port of the fan 1, and a wind direction adjustment section 3 is arranged at the end of the exhaust compression section 2 away from the fan 1; a wind guide mechanism 4 is arranged in the middle of the wind direction adjustment section 3, and an air outlet 5 is arranged at the end of the wind direction adjustment section 3 away from the exhaust compression section 2, and a wind direction adjustment mechanism 6 is arranged at the air outlet 5; both ends of the exhaust compression section 2 are provided with a connecting plate 7, and a bolt 8 is arranged in the connecting plate 7, and one end of the bolt 8 is connected to the fan 1; the cross-sectional area of the exhaust compression section 2 gradually decreases in the direction away from the fan 1 and is connected to the inside of the wind direction adjustment section 3. The exhaust compression section 2 and the wind direction adjustment section 3 constitute the main body of the exhaust hood. After the general fan 1 is installed with the exhaust hood main body and related parts, the required air volume is obtained, and the fan 1 outputs the required air volume, and the air volume passes through the exhaust compression section 2. The wind speed becomes faster, and the air flow is more concentrated, so that the air volume blown to the cooling position of the roller becomes larger.
[0026] With the help of the above scheme, the utility model can realize the exhaust of the fan 1, and by increasing the wind speed, can effectively improve the cooling effect of the rolling roller. It is suitable for the metal cooling process after heat treatment. The wind direction is adjusted according to actual needs to ensure uniform cooling and avoid uneven cooling of the metal after heat treatment.
[0027] In one embodiment, for the above-mentioned wind guide mechanism 4, the wind guide mechanism 4 includes a rotating shaft 401 arranged inside the wind direction adjustment section 3, a wind guide plate 402 is arranged on the side wall of the rotating shaft 401, a mounting bracket 403 is arranged at the bottom end of the wind direction adjustment section 3, a motor 404 is arranged inside the mounting bracket 403, and the output shaft of the motor 404 is connected to the rotating shaft 401, wherein the motor 404 is connected to a power supply to obtain the electric energy required for operation, and is connected to an external control panel to receive control instructions; limit plates 405 are arranged on both sides of the interior of the wind direction adjustment section 3, and the limit plates 405 are connected to the inner wall of the wind direction adjustment section 3 through the mounting plate 406, so that the airflow direction is adjusted by the rotation direction of the air guide plate 402 to guide the airflow, and the wind guide mechanism 4 can be automatically adjusted by the mounting bracket 403 and the internal motor 404, and the limit plates 405 can ensure that the rotation angle of the air guide plate 402 is within a safe range.
[0028] The working principle of the wind guide mechanism 4 is as follows: after receiving the command from the control panel, the motor 404 drives the rotating shaft 401 to rotate through the output shaft. The rotation of the rotating shaft 401 drives the wind guide plate 402 on its side wall to change its angle, thereby guiding the airflow in different directions. The limit plate 405 ensures that the rotation angle of the wind guide plate 402 is within the set safety range.
[0029] In one embodiment, for the above-mentioned wind direction adjustment mechanism 6, the wind direction adjustment mechanism 6 includes a fixed block 601 arranged at the end of the air outlet 5 away from the exhaust compression section 2, a slide groove 602 is arranged in the fixed block 601, two baffles 603 are arranged in the slide groove 602, and a sealing plate 604 is arranged at the end of the baffle 603 close to the wind direction adjustment section 3; a handle 605 is arranged on the outer wall of the baffle 603, and baffle rods 606 are arranged at both ends of the fixed block 601, so that the opening and closing degree and direction of the air outlet 5 can be adjusted, and then the air outlet range can be controlled to meet the needs of air cooling, and the sealing plate 604 ensures that when the wind direction is adjusted, the airflow will not leak from the baffle 603, and the baffle rod 606 provides additional protection to prevent the baffle 603 from falling off.
[0030] The working principle of the wind direction adjustment mechanism 6 is as follows: the operator adjusts the position of the baffle 603 by the handle 605. The position of the baffle 603 determines the opening and closing degree and direction of the air outlet 5, thereby controlling the direction of the airflow. In specific applications, if one side baffle 603 of the wind direction adjustment mechanism 6 is opened, the airflow is blown to the open direction through the air guide plate 402. If the two baffles 603 are opened at the same time, the air flows out from the middle of the air outlet 5, and the air guide plate 402 is located in the middle position.
[0031] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.
[0032] In actual application, after the fan 1 is started, the air is discharged through the exhaust port and enters the exhaust compression section 2. In the exhaust compression section 2, the cross-sectional area of the channel gradually decreases, so that the air flow velocity increases and the dynamic pressure increases, thereby achieving air volume compression. The position of the baffle 603 is adjusted according to demand, so that the opening position is different, and the blown wind can be directed to different cooling positions of the roller. At the same time, by adjusting the angle of the air guide plate 402 in the wind guide mechanism 4, the air flow is guided to the opening position of the wind direction adjustment mechanism 6.
[0033] In summary, the utility model can realize the exhaust of the fan 1, and by increasing the wind speed, it can effectively improve the cooling effect on the rollers. It is suitable for the cooling process of metal after heat treatment. The wind direction can be adjusted according to actual needs to ensure uniform cooling and avoid the problem of uneven cooling of metal after heat treatment. By setting the exhaust compression section 2, the wind speed is increased, and the airflow is more concentrated. The increase in wind speed can effectively increase the dynamic pressure, making the exhaust more powerful and more suitable for scenes that require forced cooling. By setting the wind guide mechanism 4, the direction of the airflow is adjusted by the rotation direction of the air guide plate 402 to achieve the guidance of the airflow. The wind guide mechanism 4 can be automatically adjusted by the mounting frame 403 and the internal motor 404, and the limit plate 405 can ensure that the rotation angle of the air guide plate 402 is within a safe range. By setting up a wind direction adjustment mechanism 6, the opening and closing degree and direction of the air outlet 5 can be adjusted, thereby controlling the air outlet range to meet the needs of air cooling. The sealing plate 604 ensures that the air flow will not leak from the baffle 603 when the wind direction is adjusted, and the baffle rod 606 provides additional protection to prevent the baffle 603 from falling off.
