Description

Technical Field

[0001] This invention relates to the field of pulse dust collector technology, specifically a pulse dust collector for cement mixing production. Background Technology

[0002] Dust collectors are key environmental protection equipment used in industrial production to capture solid particulate matter in waste gas. Their core technology is to purify dust-laden gas by using principles such as gravity settling, inertial separation, filtration, or electrostatic adsorption. Modern equipment has developed into high-efficiency bag filters, electrostatic precipitators, and their composite forms. Through intelligent dust removal control and structural optimization, filtration efficiency and operational stability have been significantly improved. They are key equipment for achieving ultra-low emissions in industries such as cement, metallurgy, and power.

[0003] Patent CN217188539U discloses a pulse-jet dust collector for cement production, relating to the field of cement production technology. The collector includes a pulse-jet body, an air inlet, a hopper, and an exhaust pipe. The air inlet is integrally formed on the left side of the pulse-jet body and is sealed to an air inlet pipe. A hopper is installed at the lower end of the pulse-jet body, and a valve is provided at the lower end of the hopper. An exhaust pipe is sealed to the upper end of the side of the pulse-jet body away from the air inlet pipe. The beneficial effect is that, through the inclusion of a dehumidification device, the gas and cement dust entering from the air inlet pipe can be dried before entering the pulse-jet body, preventing cement dust and water vapor from entering the gas. The mixed gas adheres to the dust collector filter bag, causing blockage. The combined design of the stirring and diversion devices allows cement dust or impurities settling in the hopper to flow out more quickly and effectively from the diversion port, preventing blockage. However, this device still suffers from uneven utilization of the filter bags during use, leading to localized blockages and reduced dust collection efficiency. Furthermore, the residual alkaline odor gas from the cement dust is difficult for the filter bags to handle, resulting in persistent odors in the discharged gas. Therefore, a pulse-jet dust collector for cement mixing production is proposed to address these issues. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a pulse dust collector for cement mixing production, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a pulse dust collector for cement mixing production, including a housing, a frame foot provided at the bottom of the housing, a pulse air pipe provided at the top of the housing, a distribution mechanism provided on the left side of the housing, a discharge mechanism provided at the bottom of the housing, a filter bag provided inside the housing, and a processing mechanism provided on the right side of the housing.

[0006] The sub-mechanism also includes a smoke inlet, a support frame, a reciprocating screw, and a rack. The smoke inlet is fixedly connected to the outer wall of the housing, the support frame is fixedly connected to the inner wall of the smoke inlet, the reciprocating screw is rotatably connected to the inner wall of the support frame, a motor is provided on the left side of the reciprocating screw, and the rack is fixedly connected to the inner wall of the housing.

[0007] Preferably, the sub-mechanism further includes a horizontal movable frame, a rotary drive rod, a flapping plate, and a partition plate. The horizontal movable frame is movably connected to the outer circumferential surface of the reciprocating lead screw. The rotary drive rod is rotatably connected to the outer wall of the horizontal movable frame. The flapping plate is fixedly connected to the outer wall of the rotary drive rod. The rotary drive rod and the rack are connected by gear transmission. The partition plate is fixedly connected to the inner wall of the housing.

[0008] Preferably, the sub-mechanism further includes reciprocating screw two, reciprocating screw three, reciprocating screw four, a vertical movable ring, a horizontal drive frame, a fabric pull ring, and a torsion spring fabric roll. The reciprocating screw two is rotatably connected to the inner wall of the partition plate, and the reciprocating screw two is connected to the reciprocating screw one via a bevel gear set. The reciprocating screw three is rotatably connected to the top of the partition plate, and the reciprocating screw two is connected to the reciprocating screw three via a pulley set. The reciprocating screw four is rotatably connected to the top of the partition plate, and the reciprocating screw four is connected to the reciprocating screw two via a pulley set. The vertical movable ring is movably connected to the outer circumferential surface of the reciprocating screw three. The horizontal drive frame is fixedly connected to the outer circumferential surface of the vertical movable ring. The fabric pull ring is fixedly connected to the outer wall of the horizontal drive frame. The torsion spring fabric roll is fixedly connected to the top inner wall of the machine housing. The sealing film wound around the outer circumferential surface of the torsion spring fabric roll is fixedly connected to the top of the fabric pull ring.

[0009] During operation, exhaust gas mixed with cement dust enters the device through the flue gas inlet. The motor then drives the reciprocating screw to rotate. This rotation, via the cross-shaped spiral grooves on the circumferential surface, drives the transverse movable frame to reciprocate. This reciprocating movement of the transverse movable frame drives the rotary drive rod to reciprocate, which in turn drives the dispersing blades to reciprocate. The dispersing blades then engage with the gear and rack, causing the rotary drive rod to rotate. This rotation of the rotary drive rod, in turn, drives the dispersing blades to rotate. The rotating blades contact the cement dust gas entering through the flue gas inlet, dislodging larger cement particles that fall directly into the bottom hopper under gravity. Finer particles are drawn into the filter bag by the internal blower. The reciprocating screw then rotates, driving the... The second reciprocating screw rotates, which in turn drives the third and fourth reciprocating screws to rotate via a pulley system. The rotation of the third and fourth reciprocating screws, through the intersecting spiral grooves on their circumferential surfaces, causes the vertical movable ring to reciprocate. This reciprocating motion of the vertical movable ring drives the horizontal drive frame to reciprocate, which in turn drives the fabric pull ring to reciprocate. The fabric pull ring then causes the sealing membrane, wound around the circumferential surface of the torsion spring cloth roll, to reciprocate up and down along the outer circumference of the filter bag. When the front filter bag is sealed by the sealing membrane, the rear filter bag filters dust. The rear filter bag, covered by the sealing membrane, filters dust from the front filter bag. The division of labor among multiple filter bags extends their service life, prevents premature breakage due to excessive load, stabilizes the device's filtration efficiency, and prevents partial blockage or air leakage that could reduce dust removal efficiency.

[0010] Preferably, the discharge mechanism further includes a reciprocating screw five, a winding chamber, and a dust conveying pipe. The reciprocating screw five is fixedly connected to the right side of the reciprocating screw one, the winding chamber is fixedly connected to the bottom of the machine housing, and the dust conveying pipe is fixedly connected to the bottom of the winding chamber.

[0011] Preferably, the discharge mechanism further includes a dust-discharging agitator, a drive U-rod, and an activated carbon plate. The dust-discharging agitator is rotatably connected to the inner wall of the roll chamber, the drive U-rod is movably connected to the outer circumferential surface of the reciprocating lead screw, the activated carbon plate is fixedly connected to the bottom of the drive U-rod, and the drive U-rod is slidably connected to the inner wall of the partition plate.

[0012] Preferably, the discharge mechanism further includes a sliding groove and a one-way torsion bar. The sliding groove is formed on the outer wall of the activated carbon plate, and the one-way torsion bar is rotatably connected to the bottom outer wall of the partition plate by a torsion spring.

[0013] The reciprocating screw two rotates, driving the drive U-rod to reciprocate within the housing's limit via the cross-shaped spiral grooves on the circumferential surface. This reciprocating motion of the drive U-rod causes the activated carbon plate to move up and down. During this movement, the activated carbon plate contacts the gas filtered by the filter bag, adsorbing residual alkaline impurities from the gas and reducing the concentration of alkaline particles in the exhaust gas. This prevents the alkaline gas from producing odors that could affect the surrounding environment and vegetation. The sliding chute moves downwards, pressing the one-way torsion bar to change its position from horizontal to vertical. Then, the sliding chute moves upwards, and the one-way torsion bar contacts the surface of the sliding chute, scraping the waste residue adhering to the outer wall of the sliding chute to the bottom of the device. The reciprocating screw five rotates, driving the dust-discharging agitator to rotate via the pulley assembly. The rotating agitator pushes impurities from its interior into the dust conveying pipe through the spiral blades on its outer circumferential surface, reducing manual maintenance workload and ensuring continuous and stable operation of the equipment.

[0014] Preferably, the processing mechanism includes a reciprocating lead screw six, a transverse movable ring, a helical drive rod, and a movable drive plate. The reciprocating lead screw six is ​​fixedly connected to the right side of the reciprocating lead screw five. The transverse movable ring is movably connected to the outer circumferential surface of the reciprocating lead screw five. The helical drive rod is rotatably connected to the inner wall of the housing. The movable drive plate is fixedly connected to the outer wall of the transverse movable ring and movably connected to the outer circumferential surface of the helical drive rod.

[0015] Preferably, the processing mechanism further includes a dust-sweeping soft brush, a movable block, a sliding L-shaped frame, and a smoke outlet. The dust-sweeping soft brush is fixedly connected to the outer wall of the spiral drive rod, the movable block is movably connected to the outer circumferential surface of the reciprocating lead screw, the sliding L-shaped frame is fixedly connected to the outer wall of the movable block, the smoke outlet is fixedly connected to the outer wall of the housing, and the sliding L-shaped frame is slidably connected to the inner wall of the housing.

[0016] Preferably, the processing mechanism further includes a rack two and a rotating exhaust plate. The rack two is fixedly connected to the inner wall of the smoke outlet, and the rotating exhaust plate is rotatably connected to the top of the sliding L-frame. The rotating exhaust plate and the rack two are connected by a gear set for transmission.

[0017] The rotation of reciprocating screw five drives the rotation of reciprocating screw six. The rotation of reciprocating screw six, through the cross-shaped spiral grooves on its outer circumference, drives the movable block to reciprocate. This reciprocating movement of the movable block causes the sliding L-frame to reciprocate against the inner wall of the smoke outlet. The reciprocating movement of the sliding L-frame then drives the rotating exhaust plate to reciprocate. This rotation of the exhaust plate causes the top gear to mesh with rack two, resulting in the rotating exhaust plate's rotation. This subsequently disturbs and disperses the gas exiting the smoke outlet, reducing the gas velocity and impact force during exhaust, preventing high-speed airflow from carrying away incompletely settled dust, and simultaneously reducing exhaust noise. To reduce secondary pollution to the surrounding environment, after gas filtration is complete, the device is started and run empty. Then, the reciprocating screw rotates, driving the horizontal movable ring to reciprocate through the cross-shaped spiral grooves on the circumferential surface. The reciprocating movement of the horizontal movable ring drives the movable drive plate to reciprocate. The movable drive plate contacts the outer circumferential surface of the bottom spiral drive rod, and the spiral grooves on the outer circumferential surface of the spiral drive rod cause the spiral drive rod to rotate. The rotation of the spiral drive rod drives the dust-sweeping soft brush to sweep away the cement dust adhering to the bottom of the casing, causing it to fall into the inside of the roll chamber. This reduces the frequency of manual cleaning of the inside of the device and lowers the maintenance cost of the device.

[0018] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0019] 1. This pulse-jet dust collector for cement mixing production, through the coordinated operation of the torsion spring cloth roll, horizontal movable frame, flue gas inlet, and dust collector blades, utilizes the following mechanisms: the horizontal movable frame reciprocates, driving the rotary drive rod; the rotary drive rod reciprocates, driving the dust collector blades; and the dust collector blades engage gears and racks, causing the rotary drive rod to rotate. This rotation of the rotary drive rod, in turn, drives the dust collector blades to rotate. The rotating dust collector blades contact the cement dust gas entering from the flue gas inlet, dislodging larger cement particles from the gas and causing them to fall directly to the bottom of the dust collection chamber by gravity. In the process, finer particles are drawn into the interior of the filter bag by the blower inside the device. The reciprocating movement of the cloth ring drives the sealing membrane, which is wound around the circumference of the torsion spring cloth roll, to move up and down along the outer circumference of the filter bag. The front filter bag is sealed by the sealing membrane, and the rear filter bag filters the dust. The rear filter bag is covered by the sealing membrane, and the front filter bag filters the dust. The division of labor among multiple filter bags can extend the service life of the filter bags, prevent some filter bags from breaking prematurely due to excessive load, stabilize the filtration efficiency of the device, and prevent the filter bags from being partially blocked or leaking air, which would reduce the dust removal effect.

[0020] 2. This pulse-jet dust collector for cement mixing production, with the cooperation of the drive U-rod, filter bag, and activated carbon plate, drives the U-rod to move up and down, causing the activated carbon plate to move up and down. During the up and down movement of the activated carbon plate, it comes into contact with the gas filtered by the filter bag, adsorbing the residual alkaline fine impurities of cement in the gas, thereby reducing the concentration of alkaline particles in the exhaust gas and avoiding the generation of odors from alkaline gas that may affect the surrounding environment and vegetation.

[0021] 3. This pulse-jet dust collector for cement mixing production, through the coordinated operation of the dust collection chamber, the soft brush for dust removal, the rotating dispersion plate, and the smoke outlet, causes the rotating dispersion plate to reciprocate, driving the gear and rack at the top to mesh, thereby causing the rotating dispersion plate to rotate. Subsequently, it disturbs and disperses the gas discharged from the smoke outlet, thereby reducing the flow rate and impact force of the gas during discharge, preventing the high-speed airflow from carrying away incompletely settled dust, reducing exhaust noise, and reducing secondary pollution to the surrounding environment. The rotating spiral drive rod drives the soft brush to sweep away the cement dust adhering to the bottom of the machine casing, causing it to fall into the interior of the dust collection chamber, thereby reducing the frequency of manual cleaning of the inside of the device and lowering the maintenance cost of the device.

[0032] Please see Figures 1-8 One embodiment of the present invention is: a pulse dust collector for cement mixing production, including a housing 1, a support leg 2 at the bottom of the housing 1, a pulse air pipe 3 at the top of the housing 1, a distribution mechanism 4 on the left side of the housing 1, a discharge mechanism 5 at the bottom of the housing 1, a filter bag 6 inside the housing 1, and a processing mechanism 7 on the right side of the housing 1.

[0033] Substructure 4 also includes a smoke inlet 401, a support frame 402, a reciprocating screw 403, and a rack 404. The smoke inlet 401 is fixedly connected to the outer wall of the housing 1, the support frame 402 is fixedly connected to the inner wall of the smoke inlet 401, the reciprocating screw 403 is rotatably connected to the inner wall of the support frame 402, a motor is provided on the left side of the reciprocating screw 403, and the rack 404 is fixedly connected to the inner wall of the housing 1.

[0034] The sub-mechanism 4 also includes a horizontal frame 405, a rotary drive rod 406, a flapping sheet 407, and a partition plate 408. The horizontal frame 405 is movably connected to the outer circumferential surface of the reciprocating lead screw 403. The rotary drive rod 406 is rotatably connected to the outer wall of the horizontal frame 405. The flapping sheet 407 is fixedly connected to the outer wall of the rotary drive rod 406. The rotary drive rod 406 is connected to the rack 404 via gear transmission. The partition plate 408 is fixedly connected to the inner wall of the housing 1.

[0035] Sub-mechanism 4 also includes reciprocating lead screw two 409, reciprocating lead screw three 410, reciprocating lead screw four 411, vertical movable ring 412, horizontal drive frame 413, fabric pull ring 414, and torsion spring fabric roll 415. Reciprocating lead screw two 409 is rotatably connected to the inner wall of partition plate 408. Reciprocating lead screw two 409 and reciprocating lead screw one 403 are connected via a bevel gear set. Reciprocating lead screw three 410 is rotatably connected to the top of partition plate 408. Reciprocating lead screw two 409 and reciprocating lead screw three 410 are connected via a pulley set. The fourth lead screw 411 is rotatably connected to the top of the partition plate 408. The reciprocating lead screw 411 and the second reciprocating lead screw 409 are connected by a belt pulley group. The vertical movable ring 412 is movably connected to the outer circumferential surface of the third reciprocating lead screw 410. The horizontal drive frame 413 is fixedly connected to the outer circumferential surface of the vertical movable ring 412. The fabric pull ring 414 is fixedly connected to the outer wall of the horizontal drive frame 413. The torsion spring fabric roll 415 is fixedly connected to the top inner wall of the housing 1. The sealing film wound on the outer circumferential surface of the torsion spring fabric roll 415 is fixedly connected to the top of the fabric pull ring 414.

[0036] This pulse-jet dust collector for cement mixing production uses a horizontal movable frame 405 that reciprocates, driving a rotating drive rod 406 to reciprocate. This reciprocating motion of the drive rod 406 drives a dispersing blade 407 to reciprocate, which in turn engages a gear and rack 404, causing the drive rod 406 to rotate. This rotation of the drive rod 406, in turn, causes the dispersing blade 407 to rotate. The rotating blade 407 comes into contact with the cement dust gas entering from the flue gas inlet 401, dislodging larger cement particles from the gas. These particles then fall directly into the bottom dust collection chamber 502 under gravity. Fine particles are drawn into the interior of filter bag 6 by the blower inside the device. The reciprocating movement of the cloth ring 414 drives the sealing membrane wound around the circumference of the torsion spring cloth roll 415 to move up and down along the outer circumference of the filter bag 6. When the front filter bag 6 is sealed by the sealing membrane, the rear filter bag 6 filters the dust. The rear filter bag 6 is covered by the sealing membrane while the front filter bag 6 filters the dust. The division of labor among multiple filter bags 6 can extend the service life of filter bags 6, prevent some filter bags 6 from breaking prematurely due to excessive load, stabilize the filtration efficiency of the device, and prevent the filter bags 6 from being partially blocked or leaking air, which would lead to a decrease in dust removal effect.

[0037] The discharge mechanism 5 also includes a reciprocating screw 501, a winding chamber 502, and a dust conveying pipe 503. The reciprocating screw 501 is fixedly connected to the right side of the reciprocating screw 403, the winding chamber 502 is fixedly connected to the bottom of the housing 1, and the dust conveying pipe 503 is fixedly connected to the bottom of the winding chamber 502.

[0038] The discharge mechanism 5 also includes a dust-discharging agitator 504, a drive U-rod 505, and an activated carbon plate 506. The dust-discharging agitator 504 is rotatably connected to the inner wall of the roll chamber 502. The drive U-rod 505 is movably connected to the outer circumferential surface of the reciprocating screw 409. The activated carbon plate 506 is fixedly connected to the bottom of the drive U-rod 505. The drive U-rod 505 is slidably connected to the inner wall of the partition plate 408.

[0039] The discharge mechanism 5 also includes a sliding groove 507 and a one-way torsion bar 508. The sliding groove 507 is opened on the outer wall of the activated carbon plate 506, and the one-way torsion bar 508 is rotatably connected to the bottom outer wall of the partition plate 408 by a torsion spring.

[0040] This pulse-type dust collector for cement mixing production drives the U-shaped rod 505 to move up and down, which in turn drives the activated carbon plate 506 to move up and down. During the up and down movement of the activated carbon plate 506, it comes into contact with the gas filtered by the filter bag 6, adsorbing the residual alkaline fine impurities of cement in the gas, thereby reducing the concentration of alkaline particles in the exhaust gas and preventing the alkaline gas from producing odors that may affect the surrounding environment and vegetation.

[0041] Working principle: During operation, exhaust gas mixed with cement dust enters the device through the smoke inlet 401. The motor then starts, driving the reciprocating screw 403 to rotate. During this rotation, the screw 403 drives the transverse movable frame 405 to reciprocate via the cross-shaped spiral grooves on its circumferential surface. This reciprocating movement of the transverse movable frame 405 drives the rotary drive rod 406 to reciprocate, which in turn drives the sheet-breaking mechanism 407 to reciprocate. The reciprocating movement of the sheet-breaking mechanism 407 then drives the gear... The wheel meshes with the rack 404, causing the drive rod 406 to rotate. During this rotation, the drive rod 406 drives the leaf spring 407 to rotate as well. The leaf spring 407 rotates and comes into contact with the cement ash gas entering from the flue gas inlet 401, knocking off larger cement particles. These particles fall directly into the bottom chamber 502 under gravity. Finer particles are drawn into the filter bag 6 by the blower inside the device. Subsequently, the reciprocating screw 403 rotates, passing through the bevel gear set... The reciprocating screw 2 409 rotates, which in turn drives the reciprocating screws 3 410 and 411 411 to rotate via a pulley set. The rotation of the reciprocating screws 411 and 3 410, through the intersecting helical grooves on the circumferential surface, drives the vertical movable ring 412 to reciprocate. The reciprocating movement of the vertical movable ring 412 drives the horizontal drive frame 413 to reciprocate, which in turn drives the fabric pull ring 414 to reciprocate. The reciprocating movement of the fabric pull ring 414 then drives the torsion spring. The sealing membrane wound around the circumference of the cloth roll 415 moves back and forth along the outer circumference of the filter bag 6. When the front filter bag 6 is sealed by the sealing membrane, the rear filter bag 6 filters the dust. When the rear filter bag 6 is covered by the sealing membrane, the front filter bag 6 filters the dust. The division of labor among multiple filter bags 6 can extend the service life of the filter bags 6, prevent some filter bags 6 from breaking prematurely due to excessive load, stabilize the filtration efficiency of the device, and prevent the filter bags 6 from being partially blocked or leaking air, which would reduce the dust removal effect.

[0042] The reciprocating screw 409 rotates, driving the drive U-rod 505 to reciprocate within the limit of the housing 1 via the cross-shaped spiral grooves on its circumferential surface. The reciprocating movement of the drive U-rod 505 causes the activated carbon plate 506 to move up and down. During this movement, the activated carbon plate 506 comes into contact with the gas filtered by the filter bag 6, adsorbing residual alkaline impurities from the gas, thereby reducing the concentration of alkaline particles in the exhaust gas and preventing the alkaline gas from producing odors that could affect the surrounding environment and vegetation. The sliding groove 5... 07. The downward movement of the one-way torsion bar 508 changes it from horizontal to vertical. Then, the sliding groove 507 moves upward and the one-way torsion bar 508 contacts the surface of the sliding groove 507, scraping the waste residue adhering to the outer wall of the sliding groove 507 to the bottom of the device. The reciprocating screw 501 rotates and drives the dust discharge agitator 504 to rotate through the pulley group. The rotating dust discharge agitator 504 pushes the impurities inside it into the dust conveying pipe 503 through the spiral blades on the outer circumference, thereby reducing the workload of manual operation and maintenance, while ensuring the continuous and stable operation of the equipment.

[0043] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the processing mechanism 7 includes a reciprocating lead screw 701, a transverse movable ring 702, a helical drive rod 703, and a movable drive plate 704. The reciprocating lead screw 701 is fixedly connected to the right side of the reciprocating lead screw 501, the transverse movable ring 702 is movably connected to the outer circumferential surface of the reciprocating lead screw 501, the helical drive rod 703 is rotatably connected to the inner wall of the housing 1, the movable drive plate 704 is fixedly connected to the outer wall of the transverse movable ring 702, and the movable drive plate 704 is movably connected to the outer circumferential surface of the helical drive rod 703.

[0044] The processing mechanism 7 also includes a dust-sweeping soft brush 705, a movable block 706, a sliding L-shaped frame 707, and a smoke outlet 708. The dust-sweeping soft brush 705 is fixedly connected to the outer wall of the spiral drive rod 703. The movable block 706 is movably connected to the outer circumferential surface of the reciprocating screw 701. The sliding L-shaped frame 707 is fixedly connected to the outer wall of the movable block 706. The smoke outlet 708 is fixedly connected to the outer wall of the housing 1. The sliding L-shaped frame 707 is slidably connected to the inner wall of the housing 1. A telescopic sealing plate is provided between the smoke outlet 708 and the sliding L-shaped frame 707 to reduce gas leakage when the L-shaped frame 707 slides on the inner wall of the smoke outlet 708. Since this is an air outlet, a telescopic sealing plate can be installed depending on actual needs.

[0045] The processing mechanism 7 also includes a rack 2 709 and a rotating exhaust plate 710. The rack 2 709 is fixedly connected to the inner wall of the smoke outlet 708, and the rotating exhaust plate 710 is rotatably connected to the top of the sliding L frame 707. The rotating exhaust plate 710 and the rack 2 709 are connected by a gear set.

[0046] This pulse-jet dust collector for cement mixing production uses a rotating exhaust plate 710 that reciprocates, driving the top gear and rack 709 to mesh. This causes the rotating exhaust plate 710 to rotate, disturbing and dispersing the gas discharged from the exhaust port 708. This reduces the flow rate and impact force of the discharged gas, preventing high-speed airflow from carrying away incompletely settled dust and reducing exhaust noise and secondary pollution to the surrounding environment. The rotating spiral drive rod 703 drives the dust-sweeping brush 705 to sweep away cement dust adhering to the bottom of the casing 1, causing it to fall into the inside of the dust collection chamber 502. This reduces the frequency of manual cleaning of the inside of the device and lowers the maintenance cost of the device.

[0047] Working principle: The rotation of reciprocating screw 501 drives the rotation of reciprocating screw 6 701. The rotation of reciprocating screw 6 701 drives the movable block 706 to reciprocate through the cross-shaped spiral grooves on its outer circumference. The reciprocating movement of movable block 706 drives the sliding L-frame 707 to reciprocate on the inner wall of the smoke outlet 708. The reciprocating movement of sliding L-frame 707 drives the rotating dispersion plate 710 to reciprocate. The reciprocating movement of rotating dispersion plate 710 drives the gear and rack 2 709 at the top to mesh, thereby causing rotating dispersion plate 710 to rotate. Subsequently, the gas discharged from the smoke outlet 708 is disturbed and dispersed, thereby reducing the flow velocity and impact force of the gas during discharge and preventing high-speed airflow from carrying away incompletely settled dust. Simultaneously, exhaust noise is reduced, minimizing secondary pollution to the surrounding environment. After gas filtration is complete, the device is started for no-load operation. Subsequently, the reciprocating screw 501 rotates, driving the transverse movable ring 702 to reciprocate through the cross-shaped spiral groove on the circumferential surface. The reciprocating movement of the transverse movable ring 702 drives the movable drive plate 704 to reciprocate. The movable drive plate 704 reciprocates and contacts the outer circumferential surface of the bottom spiral drive rod 703. The spiral groove on the outer circumferential surface of the spiral drive rod 703 drives the spiral drive rod 703 to rotate. The rotation of the spiral drive rod 703 drives the dust-sweeping soft brush 705 to sweep away the cement dust adhering to the bottom of the casing 1, causing it to fall into the interior of the roll chamber 502. This reduces the frequency of manual cleaning of the device's interior and lowers the maintenance cost of the device.
