[0030] As shown in Figure 3 As shown in Figure 6 As shown in Figure 7 The bottom of the long anchor rod 11 is fixedly connected with a connecting rod 24; the ends of a plurality of connecting rods 24 are fixedly connected with a connecting ring 21; during work, a plurality of long anchor rods 11 can be supported by the connecting ring 21 and the connecting rod 24 to resist the influence of external load and prevent deformation of the bottom of the long anchor rod 11; this step supports the bottom of a plurality of long anchor rods 11 by arranging the connecting ring 21 and the connecting rod 24, avoids deformation of the long anchor rod 11, and improves the structural strength of the dust removal bag.

[0031] As shown in Figures 3 to 5As shown, the bottom of the narrow mouth hoop 17 is provided with a wide mouth hoop 18, and the wide mouth hoop 18 is arranged inside the dust removal cloth 7; the inside of the wide mouth hoop 18 is fixedly connected with an embedded ring 19; in work, the narrow mouth hoop 17 maintains its shape by connecting with the fixed table 22, and the embedded ring 19 helps the wide mouth hoop 18 to maintain its shape, so that the dust removal cloth 7 maintains the shape; this step maintains the shape of the dust removal cloth 7 by arranging the embedded ring 19, avoids the collision between the dust removal cloth 7 and the components inside the dust removal cloth 7, and improves the stability of the dust collector.

[0032] As shown in Figure 1 , Figure 3 , Figure 4 and Figure 7 , the top of the fixed disc 2 is provided with air holes 3, and a plurality of air holes 3 are arranged at equal angles; in work, the purified gas inside the dust removal cloth 7 is discharged from the clean gas outlet 10 through the fixed disc 2, and the opening area of the air hole 3 at the top is increased through the air hole 3, so as to facilitate the discharge of the purified gas; this step increases the discharge rate of the purified gas by arranging the air holes 3 on the top of the fixed disc 2, which is beneficial to maintain the high pressure environment inside the sealed box 23 and improve the efficiency of the dust collector.

[0033] As shown in Figure 3 and Figure 4 , the inner side wall of the fixed disc 2 and the fixed table 22 is provided with a protrusion 25; the first fixed ring 12 and the second fixed ring 14 are provided with a protrusion 25; in work, a plurality of protrusions 25 cooperate with the bolt connection of each component to improve the tightness of each component; this step reduces the volume of each component by arranging the protrusion 25, so as to improve the space inside the dust removal cloth 7, and then increase the dust removal efficiency of the dust collector.

[0034] In operation, the gas to be filtered first enters the sealed box 23 through the turbid gas port 8. After the gas enters the sealed box 23, the air pump connected with the turbid gas port 8 continuously operates, and the air pressure in the sealed box 23 also rises accordingly, thereby forcing the gas to pass through the tiny gap on the surface of the dust removal cloth 7, filtering out the contaminated particles, and finally discharging the purified gas from the clean gas port 10 at the top of the top plate 1. During the process, the contaminated particles continuously accumulate on the surface of the dust removal cloth 7, increasing the gravity of the dust removal cloth 7. The increased gravity of the dust removal cloth 7 acts on the fixed table 22 through the narrow mouth hoop 17, and then acts on the first fixed ring 12, the tension spring 13, the second fixed ring 14, and the compression spring 15 through the fixed table 22 and the cloth bag fixing ring 16. The structure of all forces is finally transmitted to the top plate 1 and the fixed disc 2 at the top through the multiple long anchor rods 11. The tension spring 13 and the compression spring 15 are subjected to additional gravity and then produce additional deformation, causing the cloth bag fixing ring 16 between the first fixed ring 12 and the second fixed ring 14 to displace, and then pulling the narrow mouth hoop 17 through the fixed table 22, finally stretching the shape of the dust removal cloth 7, and then shaking off the contaminated particles deposited on the surface of the dust removal cloth 7. After long-term use of the dust removal cloth 7, the cleaning water is introduced into the inside of the water distribution box 5 through the water pipe 4 after stopping the dust removal work. After the water body is introduced into the inside of the water distribution box 5, the water body is evenly distributed to the inside of the four spray pipes 6 through the pipeline in the inside of the water distribution box 5, and then sprayed out from the spray head at the bottom of the four spray pipes 6. The water body sprayed out from the bottom of the spray pipe 6 penetrates and flushes the dust removal cloth 7 through the water inlet 26, thereby carrying away the substances deposited on the outer surface of the dust removal cloth 7. The deposited substances are finally deposited on the top of the sediment tank 9, and the bottom of the sediment tank 9 can be opened to clean the deposited substances. The dust removal cloth 7 is connected with the fixed disc 2 through the top sealing connecting disc 20, thereby isolating the inside of the dust removal cloth 7 from the inside of the sealed box 23. After the gas enters the inside of the sealed box 23, it cannot enter from the top of the dust removal cloth 7. The multiple long anchor rods 11 can be supported by the connecting ring 21 and the connecting rod 24 to resist the influence of external load and prevent deformation of the bottom of the long anchor rod 11. The narrow mouth hoop 17 maintains its shape by being connected with the fixed table 22, and the embedded ring 19 helps the wide mouth hoop 18 maintain its shape, thereby maintaining the shape of the dust removal cloth 7. The purified gas in the inside of the dust removal cloth 7 is discharged from the clean gas port 10 through the fixed disc 2, and the opening area at the top of the air hole 3 is increased through the air hole 3, thereby facilitating the discharge of the purified gas. The multiple protrusions 25 cooperate with the bolts to connect the components, thereby improving the tightness of the components.
