DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 6 A wall-mounted fan for a melting section comprises a mounting plate 1, a base plate 2 is mounted on the surface of the mounting plate 1 through multiple groups of buffer components, a shell 3 is fixedly mounted on the surface of the base plate 2, a rotating shaft 4 is rotatably mounted on the inner wall of the shell 3 through a support frame, a fan blade 5 is fixedly mounted on one end of the rotating shaft 4, a driving component for driving the rotating shaft 4 to rotate is provided on the base plate 2, the driving component comprises a driving motor 15 fixedly mounted on the base plate 2, a first pulley 16 sleeved on the output shaft of the driving motor 15, a second pulley 17 mounted on one end of the rotating shaft 4 through a locking component, and a transmission belt 18, the transmission belt 18 is sleeved on the first pulley 16 and the second pulley 17, and the diameter of the first pulley 16 is smaller than the diameter of the second pulley 17.

[0024] The wall-mounted fan is achieved by fixing the mounting plate 1 on the wall. When the fan is in use, the drive motor 15 is started, and the output shaft of the drive motor 15 drives the first pulley 16 to rotate, and then the second pulley 17 is driven to rotate through the transmission belt 18, and then the rotating shaft 4 is driven to rotate through the locking component, and then the fan blades 5 are driven to rotate in the shell 3 through the rotating shaft 4. The rotation of the fan blades 5 is used to supply air to the wall, thereby cooling the wall. Since the diameter of the first pulley 16 is smaller than the diameter of the second pulley 17, the rotation rate of the rotating shaft 4 is effectively increased, and the air supply rate of the fan blades 5 is increased.

[0025] A filter plate 6 is fixedly installed at one end of the shell 3 by means of screw and nut fixings, a rotating column 7 is rotatably installed on the surface of the filter plate 6, a rotating hole is opened on the surface of the rotating column 7, one end of the rotating shaft 4 passes through the rotating hole, a limiting component for driving the rotating column 7 to rotate together is provided between the rotating shaft 4 and the rotating column 7, scraping strips 8 are symmetrically fixedly installed on the surface of the rotating column 7, and the two scraping strips 8 are in sliding contact with the filter plate 6.

[0026] When the fan blades 5 rotate, the air will pass through the filter plate 6 into the shell 3 and then be discharged from the air outlet. When the air passes through the filter plate 6, the impurity particles contained in the air will be blocked by the filter plate 6 outside the shell 3, making it impossible for them to enter the shell 3. In the process of rotation, the rotating shaft 4 will drive the rotating column 7 to rotate through the limit assembly, and then the rotating column 7 will drive the two scraping strips 8 to rotate around the rotating shaft 4. The surface of the filter plate 6 is cleaned by the rotation of the two scraping strips 8, thereby preventing dust from accumulating on the surface of the filter plate 6 and affecting the air passing through the filter plate 6, thereby reducing the damage of the fan blades 5 and effectively improving the service life of the fan.

[0027] The buffer assembly includes a connecting column 9 fixedly mounted on the mounting plate 1, a buffer column 10, a telescopic spring 11 fixedly mounted on the buffer column 10, a sleeve 12 fixedly mounted on one end of the buffer column 10, a threaded column 13 fixedly mounted on the sleeve 12, and a rotating column 14 rotatably mounted on the base plate 2. A buffer groove is provided on the surface of the connecting column 9, one end of the telescopic spring 11 is fixedly connected to the inner wall of the buffer groove, the sleeve 12 is sleeved on the connecting column 9, a threaded groove is provided on the surface of the rotating column 14, and the threaded column 13 is threadedly inserted in the threaded groove.

[0028] The installation of the base plate 2 can be achieved by inserting the threaded column 13 into the threaded groove formed in the rotating column 14. When the fan is in use, vibration will be generated. Under the vibration, the telescopic spring 11 will continuously deform, thereby driving the buffer column 10 to move in the buffer groove. Under the action of the elastic force of the telescopic spring 11, the vibration can be effectively converted into elastic force, thereby reducing the vibration.

[0029] The limit assembly includes multiple limit rods 21 fixedly mounted on the rotating shaft 4, multiple limit grooves are opened on the inner circle of the rotating column 7, and the multiple limit rods 21 are respectively inserted into the multiple limit grooves. The locking component includes a threaded rod 19 fixedly mounted on one end of the rotating shaft 4 and a positioning block 20 threadedly sleeved on the threaded rod 19. The second pulley 17 is sleeved on the threaded rod 19, and the positioning block 20 is in contact with the second pulley 17.

[0030] When the filter plate 6 needs to be removed for maintenance, the positioning block 20 can be first removed from the threaded rod 19, and then the second pulley 17 can be removed from the threaded rod 19, and then the screw and nut fixings between the filter plate 6 and the housing 3 are removed, driving the filter plate 6 to move away from the housing 3, and the rotating column 7 moves along the direction of the limit rod 21 until the filter plate 6 is removed from the rotating shaft 4 for maintenance.

[0031] In the utility model, when the rotating shaft 4 drives the fan blades 5 to rotate, the air will pass through the filter plate 6 into the shell 3 and then be discharged from the air outlet. When the air passes through the filter plate 6, the impurity particles contained in the air will be blocked by the filter plate 6 outside the shell 3, making it impossible for it to enter the shell 3. In the process of rotation, the rotating shaft 4 will drive the rotating column 7 to rotate through the limit assembly, and then the surface of the filter plate 6 is cleaned by the rotation of the two scraping strips 8, preventing dust from accumulating on the surface of the filter plate 6 and affecting the air passing through the filter plate 6, effectively preventing the fan blades 5 from being damaged and improving the service life of the fan.

[0032] In general, in view of the technical problem: when the wall-mounted fan is in use, some impurity particles in the air will follow the wind direction to the inner wall of the fan. The fan blades 5 in the fan will collide with some larger particles under high-speed rotation, which may cause the fan blades 5 to be damaged, and the fan cannot be used, reducing the service life of the fan; adopting a technical solution: through the mutual cooperation of the rotating shaft 4, the limit assembly, the rotating column 7, the filter plate 6 and the scraper 8, it can effectively prevent the dust particles in the air from entering the fan with the wind direction; because the implementation process of the technical solution is: the rotating shaft 4 drives the fan blades 5 to rotate , the air will pass through the filter plate 6 into the shell 3, and then be discharged from the air outlet. When the air passes through the filter plate 6, the impurity particles contained in the air will be blocked by the filter plate 6 outside the shell 3, so that it cannot enter the shell 3, and during the rotation of the rotating shaft 4, the rotating column 7 will be driven to rotate through the limit assembly, and then the surface of the filter plate 6 will be cleaned through the rotation of the two scraper strips 8 to prevent dust from accumulating on the surface of the filter plate 6 and affecting the air passing through the filter plate 6; therefore, the technical problem can be solved inevitably, and the technical effect achieved is: effectively preventing the damage of the fan blades 5 and prolonging the service life of the fan.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
