When the exhaust gas drying device is used, the motor drives the rotating shaft 7 to rotate clockwise, the rotating shaft 7 drives the inner barrel 6 to rotate, the inner barrel 6 drives the filter cartridge 5 to rotate relative to the shell 1 through the groove 13 and the bump 14 when rotating, so that dried exhaust gas enters the shell 1 from the air inlet 2 on the left side of the shell 1, the exhaust gas is filtered by the filter cartridge 5 and then is discharged from the air outlet 3 on the rear side of the shell 1, dust in the exhaust gas is attached to the outer side of the filter cartridge 5, a clean filter surface is continuously rotated to the position of the air outlet 3 along with the continuous clockwise rotation of the filter cartridge 5, and the part attached with the dust on the filter cartridge 5 is gradually rotated to the upper part of the dust exhaust port 4;
before the long slat 11 rotates to the position above the dust exhaust port 4 along with the inner cylinder 6, the blocking rods 16 on the front side and the rear side of the long slat 11 extend into the spiral groove 18 and slide along the spiral groove 18, meanwhile, the blocking rods 16 drive the long slat 11 to continuously compress the first pressure spring 15 to move towards one end close to the rotating shaft 7, as the side wall of one end of the spiral groove 18 close to the rotating shaft 7 is an inclined surface, in the process that the long slat 11 rotates to the position right above the dust exhaust port 4, the blocking rods 16 on the front side and the rear side of the long slat 11 can be gradually extruded into the blind hole 19 by the inclined surface, when the blocking rods 16 are completely separated from the spiral groove 18, the first pressure spring 15 pushes the long slat 11 and the flat plate 12 to rapidly slide downwards along the sliding rod 10, the elasticity of the torsion spring can enable the two flat plates 12 to respectively contact with the partition plates 8 on the two sides in the downward sliding process, and the friction between the flat plates 12 and the partition plates 8 is not enough to prevent the flat plates 12 and the long slat 11 from sliding downwards, since the rotating shaft 7 is a hollow shaft and the inner cavity of the rotating shaft 7 is communicated with each chamber through a circular hole, when the strip plate 11 and the flat plate 12 slide downwards, the chamber on the long strip plate 11 does not form negative pressure to prevent the long strip plate 11 from sliding downwards, the chamber below the long strip plate 11 is quickly extruded by the long strip plate 11 and the flat plate 12, the air in the chamber is sprayed out from the air hole 9, meanwhile, as the slide bar 10 is provided with the circular groove 21, the long strip plate 11 is provided with the stop block 22 through the bolt 23 and the third pressure spring, when the strip plate 11 slides downwards, the stopper 22 will repeat the actions of embedding the circular groove 21 and compressing the third compression spring, thereby generating vibration on the slide rod 10, the vibration on the slide rod 10 is transmitted to the filter cartridge 5 through the inner cylinder 6, the dust attached to the filter cartridge 5 is backflushed to be clean under the combined action of the high-speed ejected airflow and the vibration, and the backflushed dust is discharged from the dust discharge port 4;
when the long lath 11 continuously leaves the dust exhaust port 4 clockwise along with the inner cylinder 6, the blocking rods 16 on the front side and the rear side of the long lath 11 are positioned at the outermost end of the abdicating groove 17, and the blocking rods 16 are always subjected to the elastic force given by the second pressure spring 20, and because the distance between one end of the worm-shaped groove 18 far away from the rotating shaft 7 and the rotating shaft 7 is greater than the distance between the outer end of the abdicating groove 17 and the rotating shaft 7, the blocking rods 16 on the front side and the rear side of the long lath 11 can certainly fall into the worm-shaped groove 18 under the action of the second pressure spring 20 when the inner cylinder 6 continuously rotates clockwise, and then slide along the worm-shaped groove 18 towards the direction close to the rotating shaft 7 under the driving of the rotating inner cylinder 6, in the sliding process, filtered cleaning gas enters between the long lath 11 and the outer wall of the inner cylinder 6 through the air hole 9, and the gas between the long lath 11 and the rotating shaft 7 is exhausted through the round hole and the hollow rotating shaft 7;
the chambers rotate circularly, and the part of the filter cartridge 5 which rotates to the upper part of the dust exhaust port 4 is continuously subjected to vibration and backflushing.
The invention has the following remarkable advantages:
1. when the dust filter is used, the inner cylinder 6 drives the filter cylinder 5 to rotate, so that the filter surface on the filter cylinder 5 continuously rotates between the air inlet 2 and the dust exhaust port 4 in a circulating manner, the clean filter surface rotates to the position above the dust exhaust port 4 after dust filtration work at the air inlet 2 is finished, the long strip plate 11 and the flat plate 12 in the inner cylinder 6 timely carry out backflushing on the filter cylinder 5 through the air hole 9, the phenomenon that dust adheres to the filter cylinder 5 for too long time and is scabbed due to water vapor in dried tail gas is avoided, the service life of the filter cylinder 5 is prolonged, meanwhile, the filter surface on the filter cylinder 5 which rotates to the position of the air inlet 2 each time can be always in a clean state due to timely backflushing of the filter cylinder 5, the filter effect is improved, and manual operation and shutdown are not needed in the whole process.
2. When the inner cylinder 6 of the invention recoils the filter cylinder 5, the strip plate 11 drives the two flat plates 12 to quickly blow air to the filter cylinder 5 under the action of the first pressure spring 15, and the strip plate 11 vibrates between the stop block 22 and the circular groove 21 when moving downwards along the slide bar 10, and the vibration and the air blowing disappear simultaneously, thus not only vibrating and recoiling the dust on the filter cylinder 5 and strengthening the recoiling cleaning effect, but also reducing the vibration time to the maximum extent and protecting the filter cylinder 5 from being damaged.
3. The vibration generated between the strip plate 11 and the slide bar 10 of the invention is only concentrated at the lower end of the filter cylinder 5, and the vibration of other parts is weakened in turn, thereby preventing the dust in the tail gas from being shaken off the filter cylinder 5 when the dust does not move to the upper part of the dust exhaust port 4.
