Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of bag dust removal devices, and in particular to an anti-clogging bag dust removal device. Background Art
[0002] A bag filter is a dry dust filter suitable for capturing fine, dry, non-fibrous dust. When dust-laden gas enters the bag filter, large, high-density dust particles settle due to gravity and fall into the hopper. Finer dust particles are retained as the gas passes through the filter material, resulting in purification.
[0003] In the prior art, bag-type dust collectors typically use a motor-driven screw to drive a circular array of brushes to clean dust from the filter bag surface. The cleaned dust is discharged through multiple through-holes at the bottom of the housing, preventing clogging of the filter bag surface over time. In this method, as the circular brushes move vertically to clean the dust from the filter bag surface, some dust (especially sticky dust) may remain inside the brushes because they form a circle around the filter bag surface. This affects the dust cleaning efficiency of the filter bag surface and reduces the anti-clogging effect. There is an urgent need for an anti-clogging bag-type dust collector to address this issue.

The design drives the arc-shaped connecting plate 27 to move toward the side close to the filter bag 9 through the operation of the electric push rod 28 in the anti-clogging component 2. The movement of the arc-shaped connecting plate 27 drives the arc-shaped cleaning brush 26 to contact the surface of the filter bag 9. Then, the driving motor 21 drives the rotating shaft 23 to rotate. The rotation of the rotating shaft 23 drives the pair of driving gears 24 to rotate.

The guide pipe 6 is connected to the guide tray 12 through a sealed connection.
[0025] Reference Figure 3 、 Figure 4 and Figure 5 , a pressing assembly 14 is provided at the connection points between the two ends of the filter bag 9 and the first connecting plate 82 and the second connecting plate 102 respectively; The clamping assembly 14 includes an annular connecting groove 141 formed at the end of the first connecting disc 82 or the second connecting disc 102. An annular mounting groove 143 is formed at the end of the first connecting disc 82 or the second connecting disc 102, located outside the annular connecting groove 141 and connected to the annular connecting groove 141. The end of the filter bag 9 is located within the annular connecting groove 141. An annular pressure seat 142 is provided within the annular mounting groove 143 for compressing the filter bag 9 within the annular connecting groove 141. A clamping bolt 144 is provided at the connection between the annular pressure seat 142 and the first connecting disc 82 or the second connecting disc 102, respectively. This design facilitates pressing the end of the filter bag 9 within the annular connecting groove 141 through the annular pressure seat 142 in the clamping assembly 14, improving the sealing between the filter bag 9 and the annular connecting groove 141, and facilitating the installation and replacement of the filter bag 9. At the same time, it improves the tightness of the connection between the filter bag 9 and the first connecting disc 82 or the second connecting disc 102, preventing the filter bag 9 from falling during rotation.
[0026] Reference Figure 4The annular pressure seat 142 includes a mounting ring 1422 disposed within the annular mounting groove 143. Extending from the inner wall of the mounting ring 1422 is a pressure ring 1421 located within the annular connecting groove 141. The vertical length of the pressure ring 1421 is greater than that of the mounting ring 1422, and the depth of the annular mounting groove 143 is less than that of the annular connecting groove 141. This design uses the pressure ring 1421 to press the end of the filter bag 9, improving the sealing and stability of the connection between the filter bag 9 and the annular connecting groove 141.

[0028] Reference Figures 1-9 As an embodiment of the present invention: when it is necessary to clean the dust on the surface of the filter bag 9 to prevent clogging, the staff drives the arc-shaped connecting plate 27 to move to the side close to the filter bag 9 through the electric push rod 28 in the anti-clogging component 2. The movement of the arc-shaped connecting plate 27 drives the arc-shaped cleaning brush 26 to contact the surface of the filter bag 9; then, the driving motor 21 drives the rotating shaft 23 to rotate, and the rotation of the rotating shaft 23 drives the pair of driving gears 24 to rotate. The rotation of the pair of driving gears 24 drives the ring gear 25 on the first connecting disk 82 and the second connecting disk 102 to rotate, and the rotation of the ring gear 25 on the first connecting disk 82 drives the connecting column 81 around It rotates around the first bearing 22, and the ring gear 25 on the second connecting disk 102 rotates, driving the connecting pipe 101 to rotate around the second bearing 29. The first connecting disk 82 and the second connecting disk 102 rotate at the same time, driving the filter bag 9 to rotate; then, the cleaning brush 26 contacts the surface of the rotating filter bag 9 to clean the dust on the surface of the filter bag 9. Since the filter bag 9 rotates, the separation speed of the dust and the surface of the filter bag 9 is accelerated, the speed of cleaning the dust is increased, the surface of the filter bag 9 is avoided to be blocked, and the anti-blocking effect is enhanced; at the same time, the use of the annular brush to occupy a part of the space on the surface of the filter bag 9 is avoided, so that the area of the filter bag 9 filtering the air will not be reduced, thereby improving the filtration efficiency.
[0029] When the second connecting disk 102 drives the connecting tube 101 to rotate, the fixed column 135 can rotate simultaneously with the connecting tube 101 on the second connecting disk 102. The rotation of the fixed column 135 drives the cleaning brush 134 to rotate and clean the dust between the through holes 11 inside the collection chamber 132, ensuring that the dust completely flows out of the shell 1 from the through holes 11 and enters the collection box 4 for collection.
[0030] When it is necessary to remove the dust inside the collection box 4, the dust will be concentrated at the arc-shaped cleaning port 41 under the action of the material guide slope 121 on the material guide plate 12. By opening the arc-shaped sealing plate 7, the dust at the arc-shaped cleaning port 41 is unobstructed, making it convenient to remove the dust inside the collection box 4; in order to facilitate the outflow of dust from the arc-shaped cleaning port 41, a vibration motor can be set on the collection box 4 as needed to facilitate the dust to slide along the material guide slope 121 toward the arc-shaped cleaning port 41, thereby facilitating the collection of dust.
