Wherein, ventilation slots 3011 are formed on two sides of the bottom end of the socket 403 of the sleeve 301, so as to exhaust the gas of the connection end and increase the stability during connection.
The working principle of the invention is as follows:
when the drying operation is performed, the quantity of the sludge to be screened is judged according to the quantity of the sludge to be screened, when less sludge is to be dried, the drying module 2 between the motor assembly module 1 and the discharging device 3 is disassembled, the quantity of the drying module 2 is changed, so that the maximum economic benefit is achieved, when the sludge is poured in from the top end of the motor assembly module 1, the motor of the motor assembly module 1 is started at the moment, the motor assembly module 1 rotates, when the motor assembly module 1 rotates, the stirring assembly 4 rotates through the sleeving tooth grooves 403, when the stirring assembly 4 rotates, the stirring rod 401 rotates along with the rotation, and when the stirring rod 401 rotates, the stirring rod 401 rotates due to the torsion structure, a certain thrust force is generated to push the sludge in the drying module 2, and as the temperature of the drying module 2 rises, the stirring rod 401 and the scraping smearing block 4011 are driven by the stirring assembly 4 to rotate, and the generated centrifugal force causes the tip of the scraping smearing block 4011 to be in close contact with the inner wall of the drying module 2, so that when the scraping smearing block 4011 rotates along with the stirring assembly 4, the high-temperature sludge is scraped from the inner wall of the drying module 2 by the scraping smearing block 4011 along with the temperature rising of the inner wall of the drying module 2, after the scraping, due to the mobility of the sludge, particularly the part which is not covered by the sludge, the gap between the scraping smearing block 4011 on the inner wall of the drying module 2 and the adjacent scraping smearing block 4011 is filled with the sludge which is not dried at the moment along with the scraping of the scraping smearing block 4011, and meanwhile, as the rotating speed of the stirring assembly 4 is faster, the scraped part of sludge is thrown away, so that when the temperature is too high, the thin sludge attached to the inner wall of the drying module 2 is dried, the scraping smearing block 4011 is used for scraping the dried sludge, the dried sludge falls down, the sludge is mixed with the sludge, the sludge is repeatedly started, the dryness of the sludge is kept consistent, meanwhile, due to the structural shape of the stirring rod 401, wind force is generated to push the sludge to the discharging device 3, when the motor of the motor assembly module 1 is reversed, the stirring assembly 4 is caused to reversely rotate, and when the motor of the motor assembly module 1 is reversed, the sludge is pushed by the action of the rebound spring 406 and the action of the stirring rod 401, meanwhile, due to the fact that the reverse rotation is performed, the speed is reduced when the reverse rotation is performed, the scraping smearing block 4011 is not caused to fly the sludge, the scraping smearing block 4011 is pushed to the inner wall of the drying module 2, the scraping smearing block 4011 is pushed to the rebound spring 406 by the thrust force in the smearing process, the rebound spring 406 is compressed, the rebound spring 406 is controlled to compress, and the rebound spring 406 is prevented from being continuously rotated forward and backward, and backward rotation of the rebound spring 406 is prevented from being caused to continuously;
when a large amount of sludge is required to be dried or quick drying is required, the effect can be achieved by adding the drying module 2, the discharging device 3 is detached from the drying module 2, at this time, a new drying module 2 is added between the discharging device 3 and the drying module 2, when the new drying module 2 is added, the sleeve tooth groove 403 of the new drying module 2 is aligned with the sleeve tooth bar 402 of the old drying module 2, when the sleeve is carried out, the sleeve tooth bar 402 is pushed into the sleeve tooth groove 403, the gas in the sleeve tooth groove 403 is pushed out through the spiral exhaust groove 4031, when the connection is carried out, the gas in the sleeve tooth groove 403 is discharged through the spiral exhaust groove 4031, and the special shape of the spiral exhaust groove 4031 is caused when the stirring assembly 4 rotates, because the spiral exhaust groove 4031 is positioned at one end of the sleeve tooth groove 403 to be approximately closed during rotation, so the sludge can not flow in from the spiral exhaust groove 4031 far away from the socket tooth groove 403 basically through the generated air pressure, and a small amount of sludge flows in, but due to the special shape of the spiral exhaust groove 4031, the sludge can be thrown out when rotating forward, the new socket clamping groove 202 and the heat conduction electrifying groove 201 can be sleeved with the socket clamping block 204 of the old drying module 2 and the convex block at the socket clamping block 204, after the socket is sleeved, the temporary fixing is performed by utilizing the sleeved depth, at the moment, only the fixing bolt is needed to be installed, the fixing bolt is fixed, the length of the sludge dryer is increased by repeatedly adding the drying module 2, the length of the drying box of the sludge is increased, the capacity of the dried sludge can be increased or the drying time is shortened, and the drying degree is improved.
Finally: the foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and principles of the invention are intended to be included within the scope of the invention.
