Description

Technical Field

[0001] This utility model relates to the technical field of air purification devices, specifically to a side-inserted flat cloth bag dust collector. Background Technology

[0002] Side-mounted flat bag dust collectors, as a highly efficient dry dust filtration device, have been widely used in industrial fields. Their principle is to achieve high-precision filtration through the initial dust layer formed on the surface of the filter bag. However, existing technologies still have the following significant drawbacks in practical applications: as dust accumulates on the surface of the filter bag, the system resistance increases significantly; conventional reverse-flushing cleaning methods can only remove external dust, making it difficult to completely remove internal dust accumulation; and the reverse-flushing airflow reduces the fan's cleaning efficiency and speed. Utility Model Content

[0003] I. Technical problems to be solved

[0004] The purpose of this invention is to provide a side-inserted flat bag dust collector that can quickly respond and remove dust from the inside and outside of the flat bag, preventing dust accumulation.

[0005] II. Technical Solution

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model proposes a side-inserted flat bag dust collector, including a housing. A fan is connected to the top of the housing, a dust collection hopper is arranged at the bottom, and an exhaust port is arranged in the middle. An upper frame and a lower frame are arranged between the outlet of the fan and the dust collection hopper. Multiple fixed frames are arranged and connected at equal intervals between the upper frame and the lower frame. The middle parts of the upper and lower ends of the fixed frames are rotatably connected to the upper frame and the lower frame respectively through a rotating shaft. The fixed frames are subjected to force when the fan blows air and reciprocate about the rotating shaft.

[0008] Furthermore, elastic reset members are fixed at both ends of the upper frame. The elastic reset members can abut against both sides of the upper frame when the fixed frame rotates to limit the maximum rotation angle of the fixed frame.

[0009] Furthermore, the upper frame includes a frame body and a plurality of spaced back plates fixed below the frame body, and the elastic reset member is fixed at both ends of the back plates.

[0010] Furthermore, the elastic reset component is a spring or elastic rubber pad fixed to the surface of the back plate; the elastic reset component is set at a preset distance between the two sides of the fixing frame, and the preset distance limits the maximum unobstructed rotation angle of the fixing frame before contacting the elastic reset component.

[0011] Furthermore, two fan blades are symmetrically fixed above the fixed frame; the windward surfaces of the two fan blades are arranged symmetrically in opposite directions so that the two fan blades tend to cause the fixed frame to rotate in opposite directions when facing the wind.

[0012] Furthermore, the frame body is provided with a wind deflector located above the fixed frame, and the wind deflector has a width that can cover the entire windward surface of the fan blades on one side when the fixed frame is rotated to its maximum angle.

[0013] III. Beneficial Effects

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] This invention uses springs or elastic rubber pads at both ends of the upper frame back plate as elastic reset elements to limit the maximum rotation angle of the fixed frame and buffer the impact force when it touches the reset element, while accumulating elastic potential energy. When the airflow changes and becomes disturbed, the elastic reset element releases energy, driving the fixed frame to rotate in the opposite direction, forming continuous oscillation, so that the dust on the surface of the filter bag is evenly dislodged during the periodic vibration.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please refer to a side-inserted flat bag dust collector. Figure 1-3The system includes a housing 1, with a fan 2 connected to the top, a dust collection hopper 3 at the bottom, and an exhaust port 4 in the middle. An upper frame 5 and a lower frame 6 are provided between the outlet of the fan 2 and the dust collection hopper 3. The upper frame 5 and the lower frame 6 are vertically installed and welded from channel steel. Multiple fixing frames 7 are arranged at equal intervals between the upper frame 5 and the lower frame 6. The middle parts of the upper and lower ends of the fixing frames 7 are rotatably connected to the upper frame 5 and the lower frame 6 through rotating shafts 8, respectively. The fixing frames 7 are used to fix the flat cloth bags (filter bags). When the fan 2 blows air, the fixing frames 7 are subjected to force and reciprocate about the rotating shaft 8.

[0022] The upper frame 5 includes a frame body 51 and multiple spaced back plates 52 fixed below the frame body 51. Elastic reset members are fixed at both ends of the upper frame 5. Specifically, the elastic reset members are fixed at both ends of the back plates 52. These elastic reset members can abut against the sides of the upper frame 5 when the fixed frame 7 rotates, thus limiting the maximum rotation angle of the fixed frame 7. The flat bag dust collector uses pulse-jet dust collection. Due to the instability of the fixed frame 7's rotation, when disturbed by pulse airflow or other airflow changes, the fixed frame 7 easily rotates back and forth around the axis of rotation 8 in both clockwise and counterclockwise directions. When the edge of the fixed frame 7 touches the elastic reset member, the elastic reset member buffers the impact and stores energy. When the airflow changes, the fixed frame 7 is bounced back by the elastic reset member and rotates in the opposite direction, achieving back-and-forth oscillation to prevent dust accumulation on the surface of the flat bag and reduce the dust collection effect.

[0023] The elastic reset component is a spring 9 or an elastic rubber pad fixed to the surface of the back plate 52. The elastic reset component is set at a preset distance between the two sides of the fixing frame 7. The preset distance limits the maximum unobstructed rotation angle of the fixing frame 7 before it comes into contact with the elastic reset component.

[0024] Two fan blades 10 are symmetrically fixed above the fixed frame 7; the windward surfaces of the two fan blades 10 are arranged symmetrically in opposite directions so that the two fan blades 10 have a tendency to make the fixed frame 7 rotate in opposite directions when facing the wind. By setting the fan blades 10, the response sensitivity of the fixed frame 7 to airflow disturbance is increased, so that the flat cloth bag can quickly oscillate back and forth.

[0025] A wind deflector 53 is provided on the frame body 51 above the fixed frame 7. The wind deflector 53 has a width that allows the fixed frame 7 to be rotated to its maximum angle and completely cover the fan blade 10 on one side. When the fixed frame 7 is rotated to its maximum angle, the wind deflector 53 completely covers one fan blade 10, while the other fan blade 10 is exposed outside the wind deflector 53 and blown by the wind, causing the fixed frame 7 to rotate rapidly. This process is repeated to increase the oscillation frequency of the fixed frame 7.

[0026] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. The technical content for which protection is sought in the present invention has been fully described in the claims.
