[0002] Bag dust collector is an efficient and reliable dust treatment equipment, widely used in the field of industrial dust control. Its core component is the filter bag, which is usually made of high-performance textile materials and can effectively filter dust particles in dust-laden gas. When the dust collector is working, the dust-laden gas passes through the filter bag, the dust is trapped in the bag, and the clean gas is discharged.

[0003] In industrial environments with high dust concentrations, bag dust collectors are key dust treatment equipment. During long-term operation of existing bag dust collectors, a large amount of dust will gradually accumulate on the surface of the bags, causing blockage, which will increase the resistance of the dust collector and increase energy consumption. This not only reduces the dust removal efficiency, but also aggravates the wear of the filter bags and shortens the service life of the dust collector. Summary of the invention

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the present invention provides a bag dust collector with improved service life, including a dust removal box body 1, one side of the outer wall of the dust removal box body 1 is fixedly connected to an exhaust pipe 2, the bottom of the dust removal box body 1 is fixedly connected to a conical box body 3, the outer wall of the conical box body 3 is fixedly connected to an air inlet pipe 4, the bottom of the conical box body 3 is fixedly connected to an ash discharge port 5, the inner surface wall of the conical box body 3 is fixedly connected to a cylinder 6, the outer wall of the cylinder 6 is provided with two ventilation slots 7, the inner surface wall of the dust removal box body 1 is fixedly installed with a group of fixed plates 8, and the group of fixed plates 8 are fixedly connected to the inner surface wall of the dust removal box body 1. A plurality of movable grooves 9 are provided on one side of the outer wall, and rotating rods 10 are movably inserted between the inner walls of the plurality of groups of movable grooves 9, and the outer walls of the plurality of rotating rods 10 are fixedly sleeved with flipping blocks 11, and the outer walls of the plurality of rotating rods 10 are fixedly sleeved with gears 12, and a driving motor 13 is fixedly connected to one side of the outer wall of one of the plurality of gears 12, and a mounting plate 14 is fixedly installed on the inner wall of the dust removal box 1, and a plurality of groups of mounting grooves 15 are provided on the top of the mounting plate 14, and dust removal bags 16 are fixedly inserted on the inner walls of the plurality of groups of mounting grooves 15.

[0024] The effect achieved by the entire embodiment 1 is that, driven by the fan, the dust-containing gas first enters the conical box 3 along the air inlet pipe 4, and in the conical box 3, the gas rotates downward at a high speed along the outer wall of the cylinder 6, and the larger particles are gathered on the inner wall of the conical box 3 due to the inertia generated by the rotation, and then discharged from the dust discharge port 5 under the action of gravity, and the air flow and the smaller dust particles enter the dust removal box 1 through the two ventilation slots 7 with lower air pressure in the middle of the cyclone, thereby reducing the amount of large dust particles entering the dust removal box 1. In the dust removal box 1, multiple groups of dust removal bags 16 filter the gas again to ensure the cleanliness of the exhaust gas. After a period of time, the efficiency of multiple groups of dust bags 16 will decrease due to dust accumulation. At this time, the staff starts the driving motor 13, and its output end drives the gear 12 connected to it to rotate. Through the meshing transmission between the multiple gears 12, the linkage rotation of the multiple gears 12 is realized. The multiple gears 12 then drive the multiple rotating rods 10 to rotate, causing the multiple flipping blocks 11 to rotate accordingly. One side of the flipping block 11 is designed to be in an arc shape, which will not cause damage when hitting the dust bag 16. Instead, it will effectively remove the accumulated dust on the dust bag 16 through gentle patting, restore its filtering performance, and thus extend the service life of the dust bag 16.

[0025] Embodiment 2, as Figure 2-Figure 4 As shown, the inner wall of the conical box body 3 is fixedly connected with a spray pipe 17, the outer wall of the spray pipe 17 is fixedly connected with a plurality of nozzles 18, the input end of the spray pipe 17 is fixedly connected with a delivery pipe 19, the input end of the delivery pipe 19 is fixedly connected with a water pump 20, the input end of the water pump 20 is fixedly connected with a connecting pipe 21, and the input end of the connecting pipe 21 is fixedly connected with a water tank 22.

[0026] The effect achieved by the entire embodiment 2 is that after the dust-containing gas enters the conical box 3 through the air inlet pipe 4, the staff immediately starts the water pump 20. The water pump 20 extracts clean water from the inside of the water tank 22 based on the centrifugal principle, and pressurizes the water through mechanical action, so that the water flows into the spray pipe 17 through the delivery pipe 19. The outer wall of the spray pipe 17 is fixedly connected with multiple nozzles 18. The multiple nozzles 18 can spray water evenly in the form of mist. The generation of mist water mist not only significantly increases the contact area between the gas and water, thereby improving the humidification effect, but also can effectively adsorb and settle the dust particles in the dust-containing gas, so that the dust removal efficiency of the bag dust collector is greatly improved.

[0027] Working principle: Driven by the fan, the dust-containing gas enters the conical box 3 along the air inlet pipe 4. Inside the conical box 3, the dust-containing gas rotates downward at high speed along the outer wall of the cylinder 6. The rotation inertia generates centrifugal force. When it reaches the bottom, the larger particles in the gas are separated and discharged from the ash outlet 5 by gravity. At the same time, the airflow and small dust particles enter the dust removal box 1 through the two ventilation slots 7, thereby reducing the amount of large dust particles entering the box. In this process, the staff will start the water pump 20, which draws clean water from the water tank 22 and delivers the water to the spray pipe 17 through the delivery pipe 19, and sprays the water evenly in the form of mist through multiple nozzles 18, thereby increasing the gas and water. The contact area can effectively adsorb and settle dust particles, improve the dust removal efficiency, and reduce the dust entering the dust removal box 1 again. Subsequently, the gas enters the dust removal box 1 and is filtered again through multiple groups of dust removal bags 16 to ensure the cleanliness of the exhaust gas. When the dust removal efficiency of the dust removal bags 16 is affected by dust accumulation, the staff starts the driving motor 13, and the output end of the driving motor 13 drives the gear 12 to rotate, and the transmission of multiple gears 12 drives the multiple rotating rods 10 and the multiple flipping blocks 11 to rotate. The arc-shaped surfaces of the multiple flipping blocks 11 avoid damage to the multiple groups of dust removal bags 16. By gently patting the multiple groups of dust removal bags 16, the accumulated dust is effectively removed, the filtering performance is restored, and the service life is extended.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
