The terms used herein in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings:

[0024] Dust has an adverse impact on both the production process and the production environment; since employees stay in the dusty workshop for a long time, dust is likely to accumulate in the respiratory tract, affecting the physical health of employees. For the fabric workshop, the dust generated during the production and tailoring of fabrics is also flammable, posing a safety hazard; currently, the existing dust removal equipment only has the function of sucking dust and cannot achieve self-cleaning. Therefore, it is necessary to manually clean and repair the equipment, resulting in a relatively high cost and wasting time cost due to the need to clean the dust on the equipment irregularly. Therefore, the present invention designs this scraping plate 15 polishing and dust removal equipment, and the specific structure is as Figures 1-5 shown, including a housing 1. The housing 1 includes a first cavity 2 and a second cavity 3. The second cavity 3 is located above the first cavity 2. The first cavity 2 includes a dust scraping mechanism, a dust collection vehicle 6, and multiple groups of dust removal filter bags 12. Multiple groups of dust removal filter bags 12 communicate with the second cavity 3. On one side wall of the housing 1 at the first cavity 2, there are multiple rows of dust inlet openings 4. The dust scraping mechanism is located below the dust removal filter bags 12, and the dust collection vehicle 6 is located on one side of the dust scraping mechanism. The dust scraping mechanism includes a transmission component and multiple scraping plates 15. The scraping plates 15 are vertically arranged on the transmission surface of the transmission component. (Since the transmission component in the present invention is a conveyor belt 8, there will be an upper end and a lower end. The upper end is the upper transmission part, and the lower end is the lower transmission part). When the scraping plate 15 moves horizontally at the upper end of the transmission component, the scraping plate 15 impacts on the dust removal filter bag 12 to make the dust on the surface of the dust removal filter bag 12 fall off. When the scraping plate 15 moves horizontally at the lower end of the transmission component (the scraping plate 15 conveys the dust on the bottom surface of the first cavity 2 into the dust collection vehicle 6. The length of the scraping plate 15 is greater than the distance between the upper surface of the third part and the bottom end of the dust removal filter bag 12, and the length of the scraping plate 15 is less than or equal to the distance between the lower surface of the first part and the upper surface of the dust collection plate 7), the second cavity 3 includes multiple groups of pulse back blowing mechanisms 9. The pulse back blowing mechanisms 9 respectively introduce air flow into the dust removal filter bags 12 to make the dust removal filter bags 12 expand. On the upper surface of the housing 1, there are multiple air outlet openings 5, and an exhaust fan is covered on the air outlet openings 5.

[0025] As Figures 2-5As shown in the figure, the conveying assembly includes a conveyor belt 8 and a plurality of transmission wheels 13 (in the present invention, it includes 2 driving wheels, 2 driven wheels and 4 guide wheels). The plurality of transmission wheels 13 divide the conveyor belt 8 into a first section 81, a second section 82, a third section 83 and a fourth section 84 (the two driving wheels are respectively located in the upper left and lower right, and the two driven wheels are respectively located in the lower left and upper right, so that the conveyor belt is divided into four sections, and the 4 guide wheels are located on the third section 83). The first section 81 is parallel to the bottom surface of the second cavity 3. The second section 82 is located between the first section 81 and the third section 83 and is close to the dust collecting vehicle. The fourth section 84 is located between the first section 81 and the third section 83 and is far from the dust collecting vehicle. The intersection of the second section 82 and the first section 81 is on the side of the dust collecting vehicle 6, and the intersection of the second section 82 and the third section 83 is above the dust collecting vehicle 6 (as Figure 4 shown, the end of the second section 82 connected to the driving wheel is higher than the end connected to the driven wheel, and the second section 82 is inclined towards the dust collecting vehicle 6. The purpose is to push the dust on the bottom surface of the first cavity 2 to the corner of the driven wheel at the first section 81 by the scraper 15. When the scraper 15 shovels up the dust of the first section 81 and passes through the second section 82, it will fall into the dust collecting vehicle 6).

[0026] As Figures 2-4 shown, in order to clean the fallen dust, a dust collecting plate 7 is provided on the bottom surface of the second cavity 3. The dust collecting plate 7 includes a horizontal plate 71 and an inclined plate 72. The horizontal plate 71 is located below the first section 81. The inclined plate 72 is connected to one end of the horizontal plate 71 close to the dust collecting vehicle 6, and the inclined plate 72 is parallel to the second part. The end point of the inclined plate 72 is higher than the upper opening of the dust collecting vehicle 6. A notch 14 is provided on the side of the inclined plate 72 facing the dust collecting vehicle 6. One side of the upper opening of the dust collecting vehicle 6 is located in the notch 14. When the scraper 15 brings the dust below the first section 81 to the second section 82, there is a corner here. In order to prevent the dust from falling directly below the second section 82 before falling into the dust collecting vehicle 6, it is difficult for the scraper 15 to shovel up the dust at this place, which causes difficulties for subsequent cleaning. And if there is no obstruction of the inclined plate 72, the dust below the first section 81 will be directly pushed forward by the scraper 15 and it is difficult to shovel up.

[0027] As Figure 2 shown, one end of the third section 83 close to the second section 82 is inclined downward. Since the scraper 15 enters the third section 83 after the corner of the second section 82, the scraper 15 needs to contact the dust removal filter bag 12 and slowly enter the gap between two adjacent dust removal filter bags 12, so that the shaking amplitude of the dust removal filter bag 12 will not be too large. The position of the guide wheel on the side of the third section 83 close to the dust collecting vehicle 6 is higher than the height of the driving wheel above the dust collecting vehicle 6, so that an inclined slope will be generated. The conveyor belt 8 in the present invention moves clockwise.

[0028] As Figures 2-3As shown in the figure, the pulse backflush mechanism 9 includes an air bag 91, a plurality of pulse valves 92, and a plurality of backflush pipes 93. A partition 10 is provided between the first chamber and the second chamber. The partition 10 is provided with multiple rows of equally distributed through holes 11. The dust removal filter bags 12 are connected to the through holes 11. In order to prevent the air bag 91 from blocking the through holes 11, a bracket 94 is provided on the partition 10. The air bag 91 is located on the bracket 94. A plurality of pulse valves 92 are respectively connected to the air bag 91. A plurality of backflush pipes 93 are respectively connected to the pulse valves 92. Each backflush pipe 93 is horizontally arranged above each row of through holes 11. The bottom surface of each backflush pipe 93 is provided with a plurality of backflush ports. Each backflush port is respectively aligned with the through hole 11 (here, the backflush pipe 93 includes a vertical pipe and a horizontal pipe. The vertical pipe is connected to the pulse valve 92, and the horizontal pipe is horizontally arranged above the through hole 11. The vertical pipe and the horizontal pipe are communicated).

[0029] Working principle: First, it is dust suction and dust removal. The workshop workers place the dusty materials at the dust inlet 4. The exhaust fan works. The exhaust fan sucks the air in the housing 1 outwards to generate an air flow. Then the dust on the dusty materials is sucked into the housing 1 from the dust inlet 4. After the dust enters the first cavity 2, it is filtered by the dust removal filter bags 12. The dust in the air flow is blocked on the outer surface of the dust removal filter bags 12. The filtered air flow is directly discharged from the air outlet 5. When it runs for a certain period of time, too much dust on the surface of the dust removal filter bags 12 will cause blockage. Therefore, the self-cleaning starts. The pulse backflush mechanism 9 in the second cavity 3 starts to work. The pulse valve 92 is opened. The air bag 91 injects pressurized air into the dust removal filter bags 12 through the backflush pipes 93, so that the dust removal filter bags 12 expand. The dust attached to the outer surface of the dust removal filter bags 12 will fall off onto the dust collection plate 7. The conveyor belt 8 starts to move clockwise. The scraper 15 on the conveyor belt 8 follows the conveyor belt 8 and moves clockwise. The scraper 15 pushes the dust on the dust collection plate 7 to the inclined plate 72 on one side of the dust collection vehicle 6. After the scraper 15 passes through the corner, it shovels up the dust at the junction of the horizontal plate 71 and the inclined plate 72 and drives it upwards and then pushes it to the head end of the inclined plate 72 and then into the dust collection vehicle 6. The scraper 15 then passes through the corner and enters the slope of the third section 83 and then contacts the bottom surface of the dust removal filter bag 12, slowly giving the dust removal filter bag 12 a thrust. When the scraper 15 moves, it will insert into the gap between two adjacent dust removal filter bags 12 and then continuously push the next dust removal filter bag 12, so that the passing dust removal filter bags 12 will all shake, more effectively shaking off the dust on the outer surface of the dust removal filter bags 12 and falling onto the dust collection plate 7. In this way, the self-cleaning cycle is carried out. After cleaning for a period of time, when all the dust on the dust collection plate 7 is pushed into the dust collection vehicle 6, the workshop workers can pull out the dust collection vehicle 6 from the housing 1. The wheels of the dust collection vehicle 6 are located on the track at the inner bottom of the housing 1, and the inside and outside of the housing 1 can be pulled.

[0030] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
