Then, the dust-containing gas enters the arc-shaped cavity 203 and disperses, the servo motor 5 is started by an operator through the control terminal, the servo motor 5 drives the rotating sleeve 3 to rotate through the second gear 6 and the first gear 4, the rotating sleeve 3 drives the three separating sleeves 7, the rectangular shell 9 and parts on the rectangular shell 9 to rotate, the rectangular shell 9 drives the T-shaped baffle 1203 to rotate anticlockwise, in an initial state, the T-shaped baffle 1203 is in contact with the left half part of the inner wall of the fixed shell 2, the tension spring 1204 is in a stretching state, the T-shaped baffle 1203 is sealed with one side of the rectangular shell 9 close to the separating sleeve 7, when the T-shaped baffle 1203 rotates to the front side of the arc-shaped cavity 203, the arc-shaped surface of the T-shaped baffle 1203 is in contact with the front side reducing part of the inner side of the fixed shell 2, the tension spring 1204 resets, the tension spring 1204 drives the T-shaped baffle 1203 to be far away from the separating sleeve 7, the arc-shaped baffle 1203 and parts on the rectangular shell 9 rotate anticlockwise, in the arc-shaped shell 9 is detected into the arc-shaped cavity 203, the arc-shaped surface of the T-shaped baffle 1203 is in contact with the right half part of the inner wall of the fixed shell 2, the tension spring 1204 is no longer in the stretching state, the tension spring 1204 is in the stretching state, the air in the front of the silicon carbide film is in the gap between the T-shaped baffle 1203 and the silicon carbide film 11, and the dust-containing film 11 is separated from the silicon dust in the silicon carbide film 11, and the silicon dust is in the outside of the silicon carbide film 11, and the silicon dust film 11 is separated from the silicon film 11.

Because the silicon carbide ceramic membrane 11, the rectangular shell 9 and the air inlet 202 are aligned and have equal longitudinal lengths, dust-containing gas sprayed on the silicon carbide ceramic membrane 11 is dispersed in a strip shape, and then the dust-containing gas blown out by the rectangular shell 9 is uniformly distributed on the silicon carbide ceramic membrane 11 through the rotation of the silicon carbide ceramic membrane 11. In the initial state, the electromagnetic valve in the stock sleeve 8 is in a closed state, dust-containing gas between the separating sleeve 7 and the silicon carbide ceramic membrane 11 is not conveyed downwards, and the dust-containing gas filtered by the silicon carbide ceramic membrane 11 is not conveyed downwards due to the blocking of the circular baffle 1101. Thus, the dust-containing gas (clean) filtered by the silicon carbide ceramic membrane 11 is transported upward through the gap between the barrier disc and the silicon carbide ceramic membrane 11 into the bellows 1503 and through the bellows 1503 into the exhaust chamber 301, and the gas in the exhaust chamber 301 is exhausted through the through holes of the rotating sleeve 3 and the exhaust holes 201.

In the process of rotating the rotating rod 1301, the rotating rod 1301 drives the connecting sleeve 10 to rotate through the connecting block, the connecting sleeve 10 drives the connecting frame 1502 to rotate through the fixing ring 1504 and the corrugated pipe 1503, the connecting sleeve 10 drives the silicon carbide ceramic membrane 11 to rotate, dust-containing gas sprayed out from the T-shaped baffle 1203 between the rectangular shells 9 uniformly impacts the outer side surface of the silicon carbide ceramic membrane 11, the number of teeth of the gear lack 1303 is an integral multiple of the number of teeth of the third gear 1304, in the process of meshing the number of teeth of the third gear 1304 with the gear lack 1303, the number of rotation turns of the third gear 1304 is an integral, the number of rotation turns of the silicon carbide ceramic membrane 11 is an integral, the time of each part of the outer side surface of the silicon carbide ceramic membrane 11 impacted by the dust-containing gas is equal, and the dust removal efficiency of the silicon carbide ceramic membrane 11 on the dust-containing gas is improved. For example, when the number of turns of the silicon carbide ceramic film 11 is 3, dust adhering to the outer side surface of the silicon carbide ceramic film 11 adheres to 3 layers on the outer side surface thereof, instead of the non-completed turns, resulting in uneven dust distribution. The mode avoids that the gas is singly impacted on one side of the silicon carbide ceramic membrane 11, so that the silicon carbide ceramic membrane 11 is only dedusted by one part, the rest parts basically do not participate in dedusting, the whole dedusting effect of the silicon carbide ceramic membrane 11 cannot be exerted, and the silicon carbide ceramic membrane 11 rotates to enable dust attached to the outer side surface of the silicon carbide ceramic membrane to be uniformly distributed, so that the follow-up cleaning is facilitated.

Along with the anticlockwise rotation of the rectangular shell 9, when the arc surface of the T-shaped baffle 1203 is positioned at the rear side of the arc cavity 203, the arc surface of the T-shaped baffle 1203 is contacted with the rear side diameter-changing part of the inner side surface of the fixed shell 2, the T-shaped baffle 1203 continuously rotates, the arc surface of the T-shaped baffle 1203 is extruded by the fixed shell 2 to gradually approach the separating sleeve 7, the tension spring 1204 is stretched, when the arc surface of the T-shaped baffle 1203 is contacted with the left half part of the inner wall of the fixed shell 2, the arc surface of the T-shaped baffle 1203 seals the rectangular shell 9, dust-containing gas in the arc cavity 203 does not enter the separating sleeve 7 any more, and at the moment, the arc degree of the arc surface of the T-shaped baffle 1203 is equal to the arc degree of the inner side surface of the separating sleeve 7, and the middle parts of the inner walls of the T-shaped baffle 1203, the rectangular shell 9 and the separating sleeve 7 form a complete annular curve.

When the arc surface of the T-shaped baffle 1203 is contacted with the left half part of the inner wall of the fixed shell 2, the third gear 1304 is meshed with the arc gear ring 1305, the third gear 1304 starts to reversely rotate, the third gear 1304 drives the fan blades 1306 to reversely rotate through the rotating rod 1301, gas in the exhaust cavity 301 is blown into the silicon carbide ceramic membrane 11 through the corrugated tube 1503 and impacts the blocking disc, the inclined surface of the blocking plate changes the downward flowing gas direction, so that the gas disperses to the periphery to impact the inner side surface of the silicon carbide ceramic membrane 11, and part of dust attached to the outer side surface of the silicon carbide ceramic membrane 11 is blown through the penetrating part of the inner wall of the T-shaped baffle 1203, the rectangular shell 9 and the middle part of the inner wall of the separation sleeve 7, so that the dust is prevented from entering the rectangular shell 9, the subsequent cleaning of the dust in the rectangular shell 9 is not facilitated, in the process of reversely rotating the fan blades 1306, at this time, an operator starts the electric push rod 1502 through the control terminal to drive the electric push rod 1502 to rotate through the connecting block, the electric push rod 1401 drives the sliding ring 1403 to move downwards through the first pull rod 1402, the electric push rod 1401 drives the sliding ring 1403 to blow the brush 1503 to the electric push rod 1502 down, and the electric push rod 1502 moves down through the control terminal to blow the electric push rod 1502 down, and the air flow through the connecting frame to the corrugated rod 1502 moves down through the connecting rod 1502 to the corrugated rod 1502 to move down to the silicon carbide ceramic membrane 1502, and the air is prevented from being blown down to the connecting frame to the side of the corrugated ceramic frame 1502 is blown down.

Along with the rotation of the silicon carbide ceramic film 11, the dust on the outer side surface of the silicon carbide ceramic film 11 is scraped off by the brush 1404 after contacting with the brush 1404, because the longitudinal height of the brush 1404 is positioned between the connecting frame 1502 and the blocking disk, when the blocking disk and the brush 1404 synchronously move downwards, the blocking disk changes the air direction, and the dust scraped off by the brush 1404 is blown through the silicon carbide ceramic film 11, so that the amount of dust attached on the brush 1404 is reduced, the dust attached on the outer side surface of the silicon carbide ceramic film 11 is uniformly distributed, the cleaning of the brush 1404 is facilitated, the uneven distribution of the dust attached on the outer side surface of the silicon carbide ceramic film 11 is avoided, excessive accumulation of dust is caused at a certain position, the brush 1404 is difficult to thoroughly clean the dust on the outer surface of the silicon carbide ceramic film 11, and the annular baffle 1405 is prevented from being blown to the upper part of the sliding ring 1403 by the air blown out of the silicon carbide ceramic film 11, the downward movement of the blocking disk is sequentially carried out, the inner side surface of the silicon carbide ceramic film 11 is prevented from being blown from top to bottom, the connecting frame 1502 (air outlet) is prevented from being too far, and the air speed of the silicon carbide ceramic film 11 cannot be blown uniformly from the position of the connecting frame 1502.

After the dust-containing gas treatment is completed, an operator stops the servo motor 5 through the control terminal, and opens the electromagnetic valve in the material storage sleeve 8 through the control terminal, so that the operator collects dust discharged by the material storage sleeve 8, and the device is completed.

To sum up, the separator firstly separates large-particle impurities from dust-containing gas through the filter screen of the air inlet 202, secondly adsorbs dust in the dust-containing gas through the silicon carbide ceramic membrane 11 to separate dust from the gas, and then scrapes dust on the silicon carbide ceramic membrane 11, so that multistage separation treatment is carried out on the dust-containing gas, and finally, filtration of the dust-containing gas is realized.

In the process of rotating the silicon carbide ceramic film 11, the silicon carbide ceramic film 11 drives the scraping plate 1602 to rotate through the fixing sleeve 1601, as shown in fig. 11, when the lower surface of the annular baffle 1405 is flush with the upper surface of the scraping plate 1602, the blocking plate is in contact with the circular baffle 1101, the control terminal stops the electric push rod 1401, at this time, the arc surface of the T-shaped baffle 1203 does not rotate to the arc cavity 203, along with the rotation of the scraping plate 1602, the scraping plate 1602 scrapes off dust attached to the brush 1404, the dust attached to the brush 1404 is prevented from affecting the subsequent cleaning of the silicon carbide ceramic film 11 again, the dust between the separating sleeve 7 and the silicon carbide ceramic film 11 moves downwards into the storage sleeve 8 to be collected, after the dust attached to the brush 1404 is cleaned, the control terminal starts the electric push rod 1401 to reset, and when the arc surface of the T-shaped baffle 1203 rotates to the arc cavity 203, the steps are continuously repeated to treat dust-containing gas, and the dust-containing gas is alternately removed through the three silicon carbide ceramic films 11, so that the dust removing efficiency of the separator is increased.
