DETAILED DESCRIPTION

[0023] Example

[0024] See also Figures 1-6 , the utility model provides a technical solution:

[0025] A self-cleaning bag dust collector, inside which there are two groups of fixed seats 2 fixedly connected. A dust bag 3 is installed between the two groups of fixed seats 2. The upper end of the dust collection box 1 is fixedly connected with an air duct 4, and the other end of the air duct 4 is connected to a negative pressure fan. At the same time, two symmetrically distributed dust suction pipes 5 are fixedly connected to the side surface of the lower end of the dust collection box 1. During use, by aligning the dust suction pipes 5 with the dust suction area and turning on the negative pressure fan, a negative pressure suction force is formed inside the dust collection box 1, so that dust enters the dust collection box 1 through the dust suction pipes 5 along with the air flow. Further, the dust in the gas is filtered by the dust bag 3, and solid particles are captured on the surface of the dust bag.

[0026] However, as the filtration process progresses, the dust on the surface of the dust bag 3 gradually increases, resulting in an increase in the filtration resistance, thereby affecting the dust removal efficiency and equipment performance. A cleaning mechanism 6 is installed inside the dust collection box 1. By operating the cleaning mechanism 6, the dust adhered to the surface of the dust bag 3 can be cleaned, the surface of the dust bag 3 can be cleaned, and the filtration effect of the dust bag 3 can be reset, further increasing the dust removal efficiency of this device.

[0027] The cleaning mechanism 6 includes an installation box 601 installed on the inner wall of the dust collection box 1. Inside the installation box 601, there is a motor 602 fixedly connected. A driving bevel gear 603 is fixedly connected to the output shaft of the motor 602. A vertical shaft 604 is also inserted into the installation box 601. The upper end of the vertical shaft 604 is vertically inserted into the dust bag 3, and the lower end of the vertical shaft 604 is inserted into the installation box 601 and fixedly connected with a driven bevel gear 605. The driving bevel gear 603 and the driven bevel gear 605 are meshed. A rotating cylinder 606 is fixedly connected to the surface of the vertical shaft 604 inserted into the dust bag 3. Connecting rods 607 are connected to the upper and lower surfaces of the rotating cylinder 606. Two connecting rods 607 connected to the same end of the rotating cylinder 606 are parallel and have different lengths. Scrapers 608 are installed on the surface of the rotating cylinder 606 through the connecting rods 607. The scrapers 608 are provided in two groups and are located on both sides of the rotating cylinder 606. The distance between the two groups of scrapers 608 is equal to the inner diameter of the dust bag 3.

[0028] During use, by turning on the motor 602, the motor 602 drives the driving bevel gear 603 to mesh with the driven bevel gear 605 to rotate, further controlling the vertical shaft 604 to drive the rotating cylinder 606 to rotate, so that the two groups of scrapers 608 are in contact with the inner wall of the dust bag 3. During the rotation of the scrapers 608, the dust adhered to the inner wall of the dust bag 3 can be scraped off, realizing self-cleaning of the dust bag 3 and improving the filtration effect of the dust bag 3.

[0029] When the two groups of scraping plates 608 clean the dust on the inner wall of the cloth bag 3, the two groups of scraping plates 608 always tighten the cloth bag 3. As the rotation position of the two groups of scraping plates 608 changes, the cloth bag 3 can be pulled in different directions, further enabling the scraping plates 608 to control the vibration of the cloth bag 3 during rapid rotation, thereby achieving efficient cleaning of the cloth bag 3.

[0030] An opening is provided on the lower surface of the dust collection box 1, and a collection box 10 is installed in the opening, further enabling the dust cleaned from the cloth bag 3 to fall into the collection box 10 for collection.

[0031] An electric telescopic rod 7 is fixedly connected to the side of the dust collection box 1. The piston rod of the electric telescopic rod 7 penetrates into the interior of the dust collection box 1 and is fixedly connected to a dust receiving plate 8. At the same time, a dust prevention and dust raising mechanism 9 is installed on the surface of the dust collection box 1, and the dust prevention and dust raising mechanism 9 is located on the side opposite to the electric telescopic rod 7. By operating the electric telescopic rod 7, the dust receiving plate 8 can be controlled to insert into the dust prevention and dust raising mechanism 9. Through the operation of the dust prevention and dust raising mechanism 9, the surface of the dust receiving plate 8 can be smeared with a water solution. After the dust receiving plate 8 retracts into the dust collection box 1, the dust falling from the cloth bag 3 will fall onto the surface of the dust receiving plate 8, further enabling the water solution to adhere to the dust to achieve the settlement of the dust and reduce the dust raising phenomenon inside the dust collection box 1.

[0032] The dust prevention and dust raising mechanism 9 includes a wetting box 901 connected to the surface of the dust collection box 1. An opening is provided on the surface of the dust collection box 1 and is communicated with the interior of the wetting box 901. A connecting pipe 902 is fixedly connected to the upper surface of the wetting box 901, and a water tank 903 is fixedly connected to the upper end of the connecting pipe 902. The water solution in the water tank 903 can be transported to the wetting box 901 through the connecting pipe 902. Further, after the dust receiving plate 8 is inserted into the wetting box 901, it can be wetted by the water solution, achieving surface wetting and facilitating the adhesion and collection of dust.

[0033] A push block 904 is inserted inside the humidifying box 901. A push rod 905 is fixedly connected to the upper end surface of the push block 904. The upper end of the push rod 905 penetrates into the inside of the connecting pipe 902, and a sealing plug 906 is connected to the upper end of the push rod 905. The sealing plug 906 is used to seal the inside of the connecting pipe 902 to prevent the water liquid in the humidifying box 901 from leaking. The push block 904 is trapezoidal in shape and the surface facing the dust collecting box 1 is beveled. When the dust receiving plate 8 is inserted into the humidifying box 901, it will abut against the bevel on the surface of the push block 904, further pushing the push block 904 to slide upward in the humidifying box 901. Control the push rod 905 to push the sealing plug 906 to slide upward in the connecting pipe 902, so that after the dust receiving plate 8 pushes the push block 904 to the highest position, the sealing plug 906 is inserted into the inside of the humidifying box 901, further making the sealing plug 906 unable to seal the connecting pipe 902, and enabling the water liquid in the water tank 903 to smoothly enter the humidifying box 901. Through holes 907 penetrating up and down are provided on the surface of the push block 904, so that after the water liquid enters the humidifying box 901, the surface of the dust receiving plate 8 can be wetted through the through holes 907. A spring 908 is sleeved on the surface of the push rod 905. One end of the spring 908 is connected to the inner wall of the humidifying box 901, and the other end of the spring 908 is connected to the surface of the push block 904. When the push block 904 is pushed upward, the spring 908 will be compressed at the same time. Further, after the dust receiving plate 8 slides out of the humidifying box 901, the push block 904 will reset under the elastic force of the spring 908, further realizing the re-sealing of the connecting pipe 902 by the sealing plug 906.

[0034] An opening is provided on the outer surface of the humidifying box 901, and a baffle 909 is hingedly installed in the opening. A torsion spring is provided inside the baffle 909, and the baffle 909 always seals the opening on the surface of the humidifying box 901 under the action of the torsion spring. After the dust receiving plate 8 is inserted into the humidifying box 901, pushing up the push block 904 will push the baffle 909 to rotate, further enabling the dust receiving plate 8 to penetrate out of the humidifying box 901, and during the reset process of the dust receiving plate 8, its surface will be completely wetted. Further, after the dust receiving plate 8 retracts into the dust collecting box 1, the dust falling from the cloth bag 3 will adhere to the surface of the dust receiving plate 8 and be collected. And after the dust receiving plate 8 is inserted into the anti-dust-raising mechanism 9 again, the upper surface of the dust receiving plate 8 will abut against the inner wall of the dust collecting box 1, so that the dust on the surface of the dust receiving plate 8 will be scraped off and fall into the collecting box 10 for collection. And after the dust receiving plate 8 pushes the baffle 909 to open and extends out of the humidifying box 901, it is convenient to repair the surface of the dust receiving plate 8.
