The staff is required to disassemble the disassembly plate, open the installation shell, and use the portable handle to take out the filter element and replace it. Although this design is simple and direct, it requires manual operation, which increases maintenance costs and workload. In addition, the causes of filter element blockage may include filter element quality problems, improper installation position or incorrect installation, etc. These problems may cause the filter element material to absorb too many impurities, thereby causing blockage. Therefore, when designing a dust collector, consideration should be given to adding an automatic cleaning mechanism to reduce manual intervention and improve the efficiency of equipment operation.

DETAILED DESCRIPTION
[0023] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.
[0024] Example 1
[0025] A dust removal device for processing concrete expansion agent, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, it includes a base 1, a dust removal pipe 2, an air pump 3, a filter bag 4, a filter screen 5, a collection box 6, a mounting plate 7, a rotating shaft 8, a motor 9, a transmission assembly 10 and a scraper frame 11. The dust removal pipe 2 is fixedly connected to the base 1, the air pump 3 is installed on the left side of the dust removal pipe 2, the filter bag 4 is threadedly connected to the right side of the dust removal pipe 2, the filter screen 5 is fixedly connected to the right side of the inner side of the dust removal pipe 2, the bottom wall of the dust removal pipe 2 is provided with a discharge port, and a collection box 6 is slidably connected between the base 1 and the bottom wall of the dust removal pipe 2. The collection box 6 is located just below the discharge port. The mounting plate 7 is fixed to the right side of the dust removal pipe 2, the rotating shaft 8 is rotatably connected to the mounting plate 7, a motor 9 is installed on the right side of the mounting plate 7, the output shaft on the left side of the motor 9 is connected to the rotating shaft 8 through a coupling, the scraper frame 11 is rotatably connected to the middle part of the filter 5, and a transmission assembly 10 is connected between the rotating shaft 8 and the scraper frame 11. The transmission assembly 10 consists of two pulleys and a flat belt. One pulley is fixed to the rotating shaft 8, and the other pulley is fixed to the scraper frame 11. A flat belt is wound around the two pulleys.
[0026] When using the device, first install the device on the discharge pipe of the concrete mixing station, control the air pump 3 to make the dust enter the dust removal pipe 2 from the discharge pipe, the dust will be filtered by the filter 5 first, and the concrete expansion agent remaining in the dust will be blocked by the filter 5. As the filter 5 continues to filter, the concrete expansion agent will slide along the inner wall of the dust removal pipe 2 into the collection box 6 for collection, and the extremely fine dust will continue to move to the right through the filter 5. At this time, the filter bag 4 will perform a secondary filtration on the dust. The filter bag 4 will hold the extremely fine dust, and the air with dust removed will be discharged through the filter bag 4. At the same time, the motor 9 is controlled to drive the rotating shaft 8 to rotate, thereby passing through the transmission component 10 drives the scraper frame 11 to rotate, and the rotating scraper frame 11 will scrape off the concrete expansion agent stuck on the filter screen 5 to prevent the filter screen 5 from being blocked and maintain the permeability of the filter screen 5. When the dust removal is completed, the collection box 6 can be pulled out to recycle the collected concrete expansion agent, and then 4 can be unscrewed to pour out the trapped dust. In summary, the scraper frame 11 can automatically clean the filter screen 5 during dust removal, which can effectively remove accumulated dust and avoid clogging of the filter screen 5, ensuring the dust removal effect and the long-term use of the filter screen 5, while reducing the frequency and labor intensity of manual cleaning, reducing the need for frequent replacement due to blockage, and reducing overall operating costs.
[0027] Example 2
[0028] On the basis of Example 1, Figure 1 、 Figure 6 、 Figure 7 and Figure 8As shown, it also includes a guide seat 12, a fixed plate 13, a guide plate 14, a sliding rod 15, a guide rod 17 and a cam 20. The guide seat 12 is fixed to the left inner side of the dust removal pipe 2. There are two fixed plates 13, and the fixed plates 13 are respectively fixed to the front and rear parts on the right side of the guide seat 12. Nine guide plates 14 evenly distributed vertically are rotatably connected between the two fixed plates 13. The right sides of the nine guide plates 14 are rotatably connected to the sliding rod 15. The front and rear parts of the left side of the top wall of the base 1 are fixed with guide rods 17. An elastic component is provided between the two guide rods 17, and the cam 20 is fixed to the left side of the rotating shaft 8.
[0029] like Figure 7 As shown, it also includes an elastic component, which includes a guide frame 16, a spring 18 and a mounting seat 19. The guide frame 16 is slidably connected between the two guide rods 17. Nine evenly distributed elliptical holes are opened on the front and rear sides of the guide frame 16. The sliding rods 15 slide in the adjacent elliptical holes. The guide frame 16 and the top wall of the base 1 are also slidably connected. Springs 18 are connected between the upper sides of the two guide rods 17 and the guide frame 16. The two springs 18 are both wound around the adjacent guide rods 17. The mounting seat 19 is fixed to the middle part of the upper side of the guide frame 16, and the cam 20 is squeezed into fit with the mounting seat 19.
[0030] When the motor 9 drives the rotating shaft 8 to rotate, it also drives the cam 20 to rotate together. When the rotating cam 20 contacts the mounting seat 19, the cam 20 will push the mounting seat 19 upward, thereby driving the guide frame 16 to move upward, the spring 18 will be deformed, and the guide frame 16 will drive the guide plate 14 to deflect upward through the sliding rod 15. When the rotating cam 20 separates from the mounting seat 19, under the elastic action of the spring 18, the guide frame 16 will drive the mounting seat 19 and the sliding rod 15 to move downward, thereby causing the guide plate 14 to deflect downward and reset. As the cam 20 continues to contact and separate from the mounting seat 19, the guide plate 14 deflects back and forth up and down. The reciprocating deflection of the guide plate 14 up and down will cause the air flow distribution in the dust removal pipe 2, and can generate an air flow velocity component in the same direction as the dust deposition direction inside the dust removal pipe 2, thereby improving the cleaning efficiency, reducing the equipment resistance, and extending the service life of the filter bag 4 and the filter screen 5.
[0031] It should be understood that the above description is only for illustrative purposes and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be within the scope of the claims herein.
