The second auxiliary slope body 1102 is fixedly arranged at the bottom inner side wall position of the second filtering cover cylinder 1101. The second auxiliary slope body 1102 is arranged in an annular shape. The bearing ring piece 1103 and the auxiliary placement groove body 905 are arranged in corresponding positions and have the same number of groups. The bearing ring piece 1103 is placed in the auxiliary placement groove body 905. The caliber of the second filtering cover cylinder 1101 is smaller than that of the first filtering cover cylinder 901. The outer side wall of the second filtering cover cylinder 1101 is equidistantly provided with the loading groove body 1105. The loading groove body 1105 is provided with the auxiliary structure.

[0044] The auxiliary structure here includes the adsorbing cotton board 1201, the extended installation cotton board 1202, the installation hole 1203, the auxiliary through slot body 1204, the storage auxiliary groove 1205, the auxiliary inclined groove 1206, the cleaning auxiliary strip 1207 and the auxiliary ball 1208; the extended installation cotton board 1202 is symmetrically and fixedly arranged at both ends of one side of the adsorbing cotton board 1201, the installation hole 1203 is arranged in the extended installation cotton board 1202, and the extended installation cotton board 1202 is fixed in the loading slot body 1105 through a screw; here, the auxiliary through slot body 1204 is equidistantly arranged in the adsorbing cotton board 1201, the storage auxiliary groove 1205 is equidistantly arranged at both sides of the adsorbing cotton board 1201, the slot bottom end of the storage auxiliary groove 1205 is symmetrically provided with the auxiliary inclined groove 1206, the slot body slot opening formed by the auxiliary inclined groove 1206 and the auxiliary groove 1205 is trapezoidal in shape; the cleaning auxiliary strip 1207 is equidistantly and fixedly arranged at the end of the adsorbing cotton board 1201, one end of the cleaning auxiliary strip 1207 is fixedly provided with the auxiliary ball 1208, and the auxiliary ball 1208 and the cleaning auxiliary strip 1207 are arranged in the same number.

[0045] The exhaust gas entering from the air inlet pipe 5 is first filtered and adsorbed by the cleaning auxiliary cotton bar 908 arranged on the support rod 907 in this embodiment, and the auxiliary groove 909 arranged on the side wall of the cleaning auxiliary cotton bar 908 has a simple collection and adhesion effect on the particles and other impurities in the gas. Then, the second filter cover cylinder 1101 is used for filtering and removing impurities, and finally the first filter cover cylinder 901 on the outside is used for filtering and removing impurities. The pretreated gas is then output from the gas conveying pipe 6 and enters the next processing process. In this process, the second filter cover cylinder 1101 is driven to rotate by the rotary control motor 7, and the bearing ring 1103 arranged at the bottom end of the second filter cover cylinder 1101 is inserted into the auxiliary placement groove 905 on the support disc body 31. The auxiliary ball 1104 is arranged at the bottom end of the bearing ring 1103, which facilitates the rotation of the second filter cover cylinder 1101. The rotating second filter cover cylinder 1101 performs filtering and removing impurities at the same time. During rotation, the inner side of the second filter cover cylinder 1101 also contacts the cleaning auxiliary cotton bar 908 at the corresponding position on the support rod 907. The cleaning auxiliary cotton bar 908 can provide a cleaning effect on the inner side wall of the second filter cover cylinder 1101, thereby avoiding blockage caused by excessive accumulation of impurities on the second filter cover cylinder 1101.

On the one hand, it provides a good auxiliary effect for the rotation of the bearing ring 1103 in the placement groove 905. On the other hand, the gas also has a corresponding oil sealing effect, avoiding the direct outflow of the gas from the gap between the auxiliary placement groove 905 and the bearing ring 1103.

[0046] The auxiliary structure arranged outside the second filter cover cylinder 1101 has an auxiliary effect on the removal of impurities from the gas while the second filter cover cylinder 1101 rotates, and the cleaning auxiliary strip 1207 and the auxiliary ball 1208 arranged at the end of the adsorbing cotton board 1201 also have corresponding cleaning and anti-blocking effects on the particles adhered to the inner wall of the first filter cover cylinder 901. The adsorbing cotton board 1201 is fixed by extending the mounting cotton board 1202 and cooperating with the screw, and is detachably arranged, which is convenient for subsequent cleaning and maintenance or replacement work. The adsorbing cotton board 1201 and the storage auxiliary groove 1205 arranged on the adsorbing cotton board 1201 have a corresponding adsorption effect on the particles in the gas, and the auxiliary slope groove 1206 arranged in the storage auxiliary groove 1205 makes the impurities adsorbed in the storage auxiliary groove 1205 not easy to fly out.

Part of the particles removed from the first filter cover cylinder 901 will fall on the support disc body 31, and part of the particles will fall on the second storage cavity groove 904. The second auxiliary slope body 1102 arranged inside the bottom of the first filter cover cylinder 901 also has the effect of better guiding the falling impurities to the second storage cavity groove 904.
