[0013] Beneficial effects of the utility model:

[0014] 1. During the cleaning process of the filter bag, the utility model drives all the first transmission shafts on the upper plate to rotate synchronously through the first pneumatic motor. The first transmission shaft drives the sleeve to rotate, and the sleeve drives the spiral strip to rotate. At the same time, the upper plate moves downward, driving the first transmission shaft, sleeve, and spiral strip to move downward along the inside of the filter bag. The spiral strip will continuously push the filter bag to shake left and right, so as to facilitate the breakage and falling of material lumps inside the filter bag, and at the same time scrape off the remaining residual particles inside the filter bag. When the sleeve and the spiral strip move down to the bottom of the filter bag, the electric telescopic rod extends, driving the upper plate to drive the sleeve and the spiral strip to move up and reset, thereby completing the cleaning operation.

[0015] 2. The utility model divides multiple air vents into two groups, left and right, and each group of air vents corresponds to the corresponding upper plate. The opening states of the two groups of air vents are different, but the opening states of the air vents in the same group are the same. When the filter bag at the bottom of one group of upper plates needs to be cleaned, the second pneumatic motor can be driven to rotate the second transmission shaft, and the second transmission shaft drives the driving disk to rotate, and the driving disk drives all the driven wheels to rotate, so that each group of driven wheels drives the corresponding closing disk to rotate 90°. At this time, the air vents that were blocked in the initial state are all opened, and the air vents opened in the initial state are all blocked by the closing disk. The air flow velocity inside the blocked air vents is reduced, which facilitates the cleaning of the filter bag and reduces the cleaning difficulty. This method is used to perform cyclic alternating cleaning operations on the corresponding filter bags, so that filtering and cleaning are carried out simultaneously, thereby ensuring the stability of the air pressure inside the shell.

After a long time, the material particles will form a plate on the internal surface of the filter bag 4, thereby affecting the filtering effect.

[0025] In some specific embodiments, in order to realize the rotation of the first transmission shaft 705, each group of driving components includes a rotating wheel 702, and the rotating wheels 702 are provided with multiple groups. Each group of rotating wheels 702 is coaxially fixedly connected to the corresponding first transmission shaft 705. There is a transmission wheel 703 engaged between two adjacent groups of rotating wheels 702. Each group of transmission wheels 703 is rotatably connected to the upper plate 701. The transmission wheel 703 can realize the transmission between the two adjacent groups of rotating wheels 702. The upper plate 701 is fixedly connected to the first pneumatic motor 704. The output end of the first pneumatic motor 704 is connected to one of the first transmission shafts. The driving shaft 705 is fixedly connected; when the upper plate 701 moves downward, the first pneumatic motor 704 drives the first transmission shaft 705 matched with it to rotate, the first transmission shaft 705 drives the rotating wheel 702 to rotate, the rotating wheel 702 drives the adjacent transmission wheel 703 to rotate, the transmission wheel 703 drives another group of adjacent rotating wheels 702 to rotate, and the rotating wheel 702 drives the first transmission shaft 705 fixedly connected to it to rotate. The transmission connection is performed in this way, so that all the first transmission shafts 705 on the same upper plate 701 can rotate synchronously to realize the driving of the shaking component.

[0026] In some specific embodiments, in order to achieve the shaking cleaning effect of the filter bag 4, the shaking assembly includes a sleeve 8, and the sleeve 8 is provided with multiple groups, each group of sleeves 8 is fixedly connected to the bottom of the corresponding first transmission shaft 705, and each group of sleeves 8 is surrounded by a spiral strip 10 fixedly connected to the filter bag 4; when the first transmission shaft 705 rotates, the first transmission shaft 705 will drive the sleeve 8 to rotate, and the sleeve 8 drives the spiral strip 10 to rotate. At the same time, the upper plate 701 moves downward, driving the first transmission shaft 705, the sleeve 8, and the spiral strip 10 to move downward along the inside of the filter bag 4. The spiral strip 10 will continuously push the filter bag 4 to shake left and right, so as to facilitate the breakage and falling of the material lumps inside the filter bag 4, and at the same time scrape off the remaining residual particles inside the filter bag 4. When the sleeve 8 and the spiral strip 10 move down to the bottom of the filter bag 4, the lifting assembly drives the upper plate 701 to drive the sleeve 8 and the spiral strip 10 to move upward, thereby completing the cleaning operation.

[0027] In some specific embodiments, in order to facilitate the control of the state of the air vents 5, a closing mechanism 9 is provided on the support plate frame 3, and the closing mechanism 9 includes a second pneumatic motor 901 fixedly connected to the support plate frame 3, and the output end of the second pneumatic motor 901 is fixedly connected to the second transmission shaft 902, and the output end of the second transmission shaft 902 is fixedly connected to the driving disk 903, and the air vents 5 are arranged around the driving disk 903, and each group of air vents 5 is fixedly connected to a fixed sleeve 906, and the filter bag 4 is cooperatively arranged between the fixed sleeve 906 and the support plate frame 3, and the fixed sleeve 906 is rotatably connected to the closing disk 904 inside, and the fixed sleeve 906 is rotatably connected to the side of the driving disk 903 close to the driving disk 903, and the driven wheel 905 is fixedly connected to one side of the closing disk 904; in the initial state, all the air vents 5 at the bottom of one group of upper plates 701 are controlled by the corresponding closing disk 904 4 and 904. The filter bag 4 at the bottom of the second group of upper plates 701 needs to be cleaned, and the second pneumatic motor 901 can be driven to drive the second transmission shaft 902 to rotate, and the second transmission shaft 902 drives the driving disk 903 to rotate, and the driving disk 903 drives all the driven wheels 905 to rotate, so that each group of driven wheels 905 drives the corresponding closing disk 904 to rotate 90°.

[0029] In some specific embodiments, in order to ensure the filtering effect, a rubber sleeve that cooperates with the first transmission shaft 705 is provided in the through hole; the rubber sleeve can prevent the gas inside the filter bag 4 from gushing out from the through hole, thereby avoiding contamination of the filtered airflow.

[0030] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will now be described in conjunction with specific application scenarios:

[0031] During use, the high-temperature and high-humidity airflow carries the material particles upward from the bottom of the partition 2 and enters the interior of the filter bag 4, where the material particles are filtered out. After a long time, the material particles will form a plate on the inner surface of the filter bag 4, thereby affecting the filtering effect. In the initial state, all the air vents 5 at the bottom of one of the two groups of upper plates 701 are blocked by the corresponding closing disk 904 to reduce the airflow at this position, while all the air vents 5 at the bottom of the other group of upper plates 701 are not blocked by the corresponding closing disk 904, thereby facilitating the circulation of the airflow at this position and achieving filtering of the airflow. When the filter bag 4 at the bottom of the rear group of upper plates 701 needs to be cleaned, the second pneumatic motor 901 can be driven to rotate the second transmission shaft 902, which in turn drives the driving disc 903 to rotate, and the driving disc 903 drives all the driven wheels 905 to rotate, so that each group of driven wheels 905 drives the corresponding closing disc 904 to rotate 90°. At this time, the air vents 5 that were blocked in the initial state are all opened, and the air vents 5 that were opened in the initial state are all blocked by the closing disc 904. The air flow velocity inside the blocked air vents 5 is reduced, thereby facilitating the cleaning of the filter bag 4 and reducing the cleaning difficulty.

[0032] At this time, the electric telescopic rod 6 drives the upper plate 701 to move downward, and then drives the corresponding first transmission shaft 705 to move downward. When the upper plate 701 moves downward, the first pneumatic motor 704 drives the first transmission shaft 705 matched therewith to rotate, and the first transmission shaft 705 drives the rotating wheel 702 to rotate, and the rotating wheel 702 drives the adjacent transmission wheel 703 to rotate, and the transmission wheel 703 drives another set of adjacent rotating wheels 702 to rotate, and the rotating wheel 702 drives the first transmission shaft 705 fixedly connected thereto to rotate. The transmission connection is performed in this way, so that all the first transmission shafts 705 on the same upper plate 701 can be synchronized. Rotation. When the first transmission shaft 705 rotates, the first transmission shaft 705 will drive the sleeve 8 to rotate, and the sleeve 8 will drive the spiral strip 10 to rotate. At the same time, the upper plate 701 moves downward, driving the first transmission shaft 705, the sleeve 8, and the spiral strip 10 to move downward along the inside of the filter bag 4. The spiral strip 10 will continuously push the filter bag 4 to shake left and right, so as to facilitate the breakage and falling of the material agglomerates inside the filter bag 4, and at the same time scrape off the remaining residual particles inside the filter bag 4. When the sleeve 8 and the spiral strip 10 move down to the bottom of the filter bag 4, the electric telescopic rod 6 extends, driving the upper plate 701 to drive the sleeve 8 and the spiral strip 10 to move up and reset, thereby completing the cleaning operation.

[0033] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
