Description

Technical Field

[0001] This utility model relates to the field of fan air regulation technology, specifically to an air volume regulating mechanism for an air supply system. Background Technology

[0002] In industrial production and ventilation systems, airflow regulation is a crucial element in ensuring efficient and stable system operation. Especially in air supply systems, the airflow from fans needs to be precisely adjusted according to actual needs to meet ventilation requirements under different operating conditions. Traditional airflow regulation methods often employ fixed ducts or manual regulating valves. These methods suffer from drawbacks such as low adjustment accuracy, slow response speed, and complex operation, making it difficult to meet the demands of modern industry for automated and intelligent control.

[0003] With the continuous development of fan technology, dual-inlet induced draft fans have been widely used in air supply systems due to their high efficiency and energy saving. However, the problem of adjusting the air intake volume of dual-inlet induced draft fans has also become prominent. Traditional adjustment methods are difficult to achieve precise and rapid adjustment of the air inlets on both sides of the dual-inlet induced draft fan, resulting in uneven air volume distribution in the system and affecting the overall ventilation effect.

[0004] Therefore, it is particularly important to develop a mechanism that can accurately and quickly adjust the airflow of a dual-inlet induced draft fan. This mechanism needs to overcome the shortcomings of traditional adjustment methods, improve the accuracy and response speed of airflow regulation, while simplifying the operation process and reducing maintenance costs, in order to meet the high demands of modern industry on air supply systems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and provide an air volume adjustment mechanism for an air supply system. Through the innovative design of the air adjustment components and drive mechanism, it can achieve precise and rapid adjustment of the air volume of the dual-inlet induced draft fan.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: an air volume regulating mechanism for an air supply system, including a frame, on which a dual-inlet induced draft fan is installed, and an air regulating component is installed on the frame corresponding to the air inlet positions of the dual-inlet induced draft fan. The air regulating component includes air regulating plates that are movably covered on both sides of the air inlet positions of the dual-inlet induced draft fan, and a driving mechanism is provided on the frame for driving the air regulating plates to slide along the conveying direction of the sorting and conveying surface. The driving mechanism drives the air regulating plates to slide, thereby adjusting the air volume of the dual-inlet induced draft fan.

[0007] To further optimize this utility model, the following technical solutions may be preferred:

[0008] Preferably, a support base is provided on the frame corresponding to the position of the dual air inlet induced draft fan, and a suspension plate is provided on the frame corresponding to the top position of the air inlets on both sides of the dual air inlet induced draft fan, with the top of the air regulating plate being clamped on the suspension plate.

[0009] Preferably, the drive mechanism includes an adjusting rod rotatably mounted on the frame, an adjusting gear being provided on the adjusting rod corresponding to the position of the air regulating plate, and a driven rack portion cooperating with the adjusting gear being provided on the top of the air regulating plate.

[0010] Preferably, one end of the adjusting rod extends through the frame and is coaxially provided with an adjusting handle or a rotary driver.

[0011] Preferably, a gap is reserved between the air regulating plate and the air inlet of the dual-inlet induced draft fan.

[0012] Preferably, an air supply grille is provided on the frame at the air outlet position corresponding to the dual air inlet induced draft fan.

[0013] The air volume regulating mechanism for the air supply system of this utility model has significant advantages over traditional air volume regulating methods, specifically in the following aspects:

[0014] (1) Precise air volume adjustment: Through the movable air regulating plates installed at the air inlets on both sides of the dual-inlet induced draft fan, and the driving mechanism that drives the air regulating plates to slide, this utility model can achieve precise adjustment of the air volume of the dual-inlet induced draft fan. This adjustment method not only improves the accuracy of air volume control, but also enables the system to flexibly adjust the air volume according to actual needs, so as to meet the ventilation needs under different working conditions.

[0015] (2) Improve system efficiency: Due to its ability to precisely adjust the air volume, the adjustment mechanism of this utility model helps to optimize the overall efficiency of the air supply system. By reducing unnecessary air volume loss and energy consumption, the system can achieve higher ventilation effect with lower energy consumption, thereby improving energy utilization and system economy.

[0016] (3) Enhanced system stability: By precisely controlling the air intake of the dual-intake induced draft fan, this utility model helps to maintain the stability of the air supply system. When the air volume demand changes, the system can quickly respond and adjust the air volume to avoid system fluctuations caused by excessive or insufficient air volume, thus ensuring stable system operation.

[0017] (4) Simplified operation process: Compared with the traditional manual adjustment method, the adjustment mechanism of this utility model adopts automatic control, which greatly simplifies the operation process. Users can achieve precise adjustment of air volume through the control panel or remote control system, reducing the difficulty of operation and labor intensity.

[0018] (5) Reduced maintenance costs: Due to the adoption of automated control, the adjustment mechanism of this utility model reduces the frequency of manual intervention and lowers the risk of equipment damage caused by improper operation or frequent adjustments. At the same time, the precise adjustment method also helps to extend the service life of the equipment, thereby reducing maintenance costs.

[0019] In summary, the air volume regulating mechanism for the air supply system of this utility model has significant beneficial effects such as precise air volume regulation, improved system efficiency, enhanced system stability, simplified operation procedures, and reduced maintenance costs. It is of great significance for improving the overall performance and economic benefits of the air supply system. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1:

[0027] like Figure 1-4 As shown, an air volume regulating mechanism for an air supply system includes a frame 1, on which a dual-inlet induced draft fan 2 is mounted. An air regulating component 3 is mounted on the frame 1 corresponding to the air inlet positions of the dual-inlet induced draft fan 2. The air regulating component includes air regulating plates 10 that are movably covered at the air inlet positions on both sides of the dual-inlet induced draft fan. A drive mechanism is mounted on the frame for driving the air regulating plates to slide along the conveying direction of the sorting conveying surface. The drive mechanism drives the air regulating plates to slide, thereby adjusting the air volume of the dual-inlet induced draft fan.

[0028] The frame 1 is equipped with a support base 5 corresponding to the position of the dual air inlet induced draft fan. The frame is equipped with a suspension plate 11 at the top position of the air inlets on both sides of the dual air inlet induced draft fan. The top of the air regulating plate is fixed on the suspension plate 11. Specifically, the top of the air regulating plate is designed with a bending part 9, which overlaps the suspension plate. The drive mechanism includes an adjusting rod 12 rotatably mounted on the frame. The adjusting rod is equipped with an adjusting gear 13 corresponding to the position of the air regulating plate. The top of the air regulating plate is equipped with a driven rack part 14 that cooperates with the adjusting gear.

[0029] One end of the adjusting rod 12 extends through the frame 1 and is coaxially mounted with an adjusting handle or a rotary drive. The adjusting handle facilitates manual operation, while the rotary drive enables automated control, improving the operational flexibility and intelligence level of the equipment.

[0030] A gap 8 is reserved between the air regulating plate 10 and the air inlet of the dual-inlet induced draft fan 2. This design helps to reduce friction and collision between the air regulating plate and the air inlet of the dual-inlet induced draft fan during movement, thereby reducing wind resistance and noise. At the same time, the gap can also act as an airflow buffer, allowing the airflow to enter the dual-inlet induced draft fan more smoothly and improving the utilization efficiency of wind energy.

[0031] An air supply grille 4 is installed on the frame 1 at the air outlet position corresponding to the dual-inlet induced draft fan 2; this allows for more effective control of the airflow direction and speed. The air supply grille can evenly disperse the airflow, reduce airflow turbulence and eddy currents, and make the airflow act more smoothly on the material, thereby improving the accuracy and stability of sorting.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
