Description

Technical Field

[0001] This utility model relates to the field of centrifugal fan technology, and in particular to an adjustable exhaust port centrifugal fan. Background Technology

[0002] Centrifugal fans are a type of impeller machinery widely used in energy, environment, aviation and other fields, and are one of the main energy-consuming equipment in industrial and agricultural production. Centrifugal fans are one of the four major components of dust removal and ventilation systems. They are relatively precise operating machines that rely on the rotation of the impeller to create negative pressure inside the fan, drawing in outside air and discharging it through the impeller channel and volute.

[0003] In the existing technology, by installing centrifugal fans on industrial plants, the centrifugal fans can quickly extract dust and impurities generated in the production process from the plant with their strong suction capacity, and then introduce fresh outdoor air through the air intake device to form air convection between the inside and outside of the plant. However, during the use of centrifugal fans, the gas exhaust end is directional and cannot be changed. It can only exhaust air in a fixed direction. When it is necessary to adjust the exhaust direction according to the external environment of the factory, since the centrifugal fan is fixed at the installation point in the factory, the only way to adjust the airflow direction is to add an extra air guide duct.

The port of hole 16 is fixedly connected to one end of the connecting cavity 18. An inner frame 19 is provided on the inner surface of the connecting cavity 18. The inner surface of the connecting cavity 18 is rotatably connected to one side of the inner frame 19. A filter screen 110 is provided on the inner surface of the inner frame 19. The inner surface of the inner frame 19 is fixedly connected to the outer side of the filter screen 110. A connecting plate 12 is provided at one end of the tapered tube 13. One end of the tapered tube 13 is fixedly connected to one end of the connecting plate 12. A fan body 11 is provided on the inner side of the connecting plate 12. The inner side of the connecting plate 12 is connected to the fan body 11. The connecting end is fixedly connected. A motor 17 is provided on the inner surface of the tapered tube 13. The inner surface of the tapered tube 13 is fixedly connected to the outer side of the motor 17. The output end of the motor 17 is fixedly connected to the center of the tapered tube 14. A cavity 112 is provided on one side of the connecting cavity 18. One side of the connecting cavity 18 is fixedly connected to one end of the cavity 112. A brush plate 115 is provided on the inner surface of the cavity 112. The inner surface of the cavity 112 fits into the outer side of the brush plate 115. A side plate 114 is provided at one end of the brush plate 115. One end of plate 115 is fixedly connected to one end of side plate 114. The outer side of side plate 114 is slidably connected to the inner wall of cavity 112. A telescopic rod 113 is provided on one side of side plate 114. One side of side plate 114 is fixedly connected to one end of telescopic rod 113. The other end of telescopic rod 113 is fixedly connected to the top side of cavity 112. A second motor 111 is provided on one side of inner frame 19. One side of inner frame 19 is fixedly connected to the output end of second motor 111. One end of second motor 111 is fixedly connected to one side of connecting cavity 18.

[0023] In this embodiment, the adjustable exhaust centrifugal fan is used by installing a connecting plate 12 at the exhaust port of the fan body 11. One end of the connecting plate 12 is fixed with a cone tube 13, and the two are fixedly connected. Four corresponding holes 15 are opened on the outer side of the cone tube 13. The four corresponding holes 15 are equidistantly distributed and face different directions. Since a cone tube 2 14 is installed on the outer side of the cone tube 13 in a sleeve manner, the cone tube 13 is located on the inner surface of the cone tube 2 14 and in contact with it. A corresponding hole 2 16 is opened on the cone tube 2 14, and a motor is installed at the center of the inner surface of the cone tube 13. Motor 17 is fixed at the center of cone tube 14, so that when motor 17 starts, it can drive cone tube 14 to rotate around cone tube 13. By rotating cone tube 14, the corresponding hole 16 can be aligned with one of the four corresponding holes on cone tube 13. At this time, the fan can only exhaust air through the aligned hole, realizing directional exhaust in a single direction. If it is necessary to switch the exhaust direction, simply control motor 17 to drive cone tube 14 to rotate until the corresponding hole 16 is aligned with the corresponding hole 15 in another direction. At the same time, the fitting design of cone tube 13 and cone tube 14 can reduce airflow leakage in non-directional holes. A connecting cavity 18 is installed at the port corresponding to hole 16. An inner frame 19 is designed on the inner surface of the connecting cavity 18. A filter screen 110 is located in the inner frame 19. The filter screen 110 is made of high-density metal mesh, which can intercept dust and impurities in the air during the exhaust process. A cavity 112 is installed on one side of the connecting cavity 18. A brush plate 115 is designed on the inner surface of the cavity 112. At this time, by starting the motor 111, the inner frame 19 drives the filter screen 110 to rotate 180 degrees, so that the side with dust adhesion faces the inner frame 110. Since a side plate 114 is installed on one side of the brush plate 115, and a telescopic rod 113 is connected to one side of the side plate 114, the brush plate 115 slides out of the cavity 112 and is located on the filter plate by retracting the telescopic rod 113. Then, the brush plate 115 cleans the filter plate by extending and retracting. During the cleaning process, the dust is rubbed, and the dust and impurities are mixed together, so the cleaned object will be fluffy. Even if it falls on the surface of the object after being scattered, it is easy to be treated.

[0024] Example 2 like Figure 1-5 As shown, the auxiliary mechanism 2 includes a baffle 21, a motor 22 is provided at the bottom end of the baffle 21, the bottom end of the baffle 21 is fixedly connected to the output end of the motor 22, the outer side of the motor 22 is fixedly connected to one side of the connecting cavity 18, and the top end of the baffle 21 is located above the top end of the connecting cavity 18.

[0025] In this embodiment, a baffle 21 is installed above the connecting cavity 18. The baffle 21 can cover the top of the connecting cavity 18 during special weather conditions to prevent rainwater from entering the fan through the connecting cavity 18. During normal weather conditions, a motor 22 is installed at the bottom of the baffle 21 and fixed to one side of the connecting cavity 18. By starting the motor 22, the baffle 21 can be rotated 90 degrees, so that the baffle 21 is no longer located above the top of the connecting cavity 18, thereby further improving the adaptability and safety of the fan under different weather conditions.

[0026] Working principle: like Figure 1-6 As shown, a connecting plate 12 is installed at the exhaust port of the fan body 11. A cone tube 13 is fixed to one end of the connecting plate 12. A cone tube 2 14 is installed on the outside of the cone tube 13 in a sleeve manner. When the motor 17 starts, it can drive the cone tube 2 14 to rotate around the cone tube 13. By rotating the cone tube 2 14, the corresponding hole 2 16 can be aligned with one of the four corresponding holes on the cone tube 13. At this time, the fan can only exhaust air through the aligned hole, realizing directional exhaust in a single direction. If it is necessary to switch the exhaust direction, simply control the motor 17 to drive the cone tube 2 14 to rotate until the corresponding hole 2 16 aligns with one of the four corresponding holes on the cone tube 13. Align the corresponding hole 15 in the other direction. Next, a connecting cavity 18 is installed at the port of the corresponding hole 16. The inner surface of the connecting cavity 18 is designed with an inner frame 19. The inner frame 19 contains a filter screen 110. The filter screen 110 is made of high-density metal mesh, which can intercept dust and impurities in the air during the exhaust process. By starting the motor 111, the inner frame 19 drives the filter screen 110 to rotate 180 degrees, so that the dust-attached surface faces upward. The telescopic rod 113 is retracted. Then, by extending and retracting, the brush plate 115 cleans the filter plate. The cleaned objects will be fluffy and easy to process.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
