Description

Technical Field

[0001] This invention relates to the field of feeding device technology, and proposes an anti-clogging fly ash feeding device. Background Technology

[0002] Fly ash is the ash produced after coal combustion. It is a good building material, often used to manufacture fly ash bricks. Fly ash is usually transported by pneumatic conveyor and screw conveyor. During the operation of screw conveyors, the fly ash needs to be manually transported to the transport port. During the manual transport of fly ash with shovels, the fly ash is constantly in contact with the outside environment, which easily causes dust and leads to environmental pollution. Pneumatic conveying devices use a suction fan to generate a high-speed airflow to suck the fly ash into the pipe. The high-speed airflow can quickly carry away the fly ash and prevent it from spreading and flying. Although pneumatic conveying devices can prevent fly ash from flying during transportation, the fly ash needs to be sucked to a high place through the pipe so that it can settle and enter the transport vehicle through the discharge pipe below. At the corner where the pipe rises vertically from the ground, if the fly ash becomes damp and clumps, the suction in the pipe will not be able to carry the clumps up, causing the clumps to accumulate at the corner and block the passing fly ash, eventually causing blockage and affecting transportation efficiency. Summary of the Invention

[0003] In order to overcome the disadvantage that when fly ash gets damp and clumps together, the clumps accumulate in the pipes and cause blockages, the present invention provides a blockage-proof fly ash feeding device.

[0011] Furthermore, it also includes a suction mechanism for sucking fly ash into the first hose. The suction mechanism is located at the end of the second hose away from the second auger. The suction mechanism includes a handle that is slidably connected to the second hose. The handle is fixedly connected to a second fixing member. The second hose is fixedly connected to circumferentially distributed second fixing rods. The second fixing member is slidably connected to an adjacent second fixing rod. A bracket is fixedly connected to the second fixing rod away from the second fixing member. The first hose is fixedly connected to circumferentially distributed limiting plates.

[0014] The present invention has the following advantages: The present invention uses a suction component in conjunction with the first and second augers to move the solid particles generated by moisture in the fly ash upward, preventing the solid particles from depositing below the bend and causing blockage of the bend. At the same time, the second auger rotates continuously, spreading the fly ash on the surface of the second auger, reducing fly ash accumulation and facilitating the upward transport of fly ash.

[0015] When fly ash accumulates in the first hose, it moves into the first hose through the air outlet shell on the lower side of the fly ash accumulation. During the movement, the integrity of the accumulated fly ash is disrupted. Under the negative pressure inside the first hose and the positive pressure between the first hose and the second hose, air enters the first hose through the air outlet shell, blowing away and dispersing the accumulated fly ash, thus maintaining the ventilation of the first hose.

[0016] Even after the fly ash buries the discharge port below the third hose, it can still be discharged by the push of the third auger. Because the accumulated fly ash buries the discharge port, the discharged fly ash squeezes the accumulated fly ash below, thereby stabilizing the discharged fly ash and reducing the fly ash from flying.

[0017] The automatic movement of the moving ring allows for convenient adsorption of fly ash in narrow spaces, and automatically adjusts the suction force of the second suction pipe in four directions, improving the efficiency of the second suction pipe in adsorbing fly ash and saving the manual process of constantly adjusting the position of the first hose.

The first auger 202 is rotatably connected to the bend 106 and is located inside the bend 106. A straight pipe 203 is fixedly connected to the bend 106 through a square plate. The straight pipe 203 is used for... For transporting solid particles, a first auger 202 is rotatably connected to a straight pipe 203. A second auger 204 is fixedly connected to the lower side of the first auger 202. The second auger 204 is provided with filter holes, and its diameter gradually decreases from bottom to top. An annular baffle is provided at the edge of the second auger 204 to prevent solid particles from falling off. An anti-clogging component 3 is provided between the first hose 107 and the second hose 108 to prevent powder from entering the first hose 107. The coal ash is accumulated. The material tank 102 is equipped with a feeding mechanism 4 for feeding. A straight pipe 203 is connected to a discharge pipe 205. The discharge pipe 205 is fixedly connected to and connected to a storage shell 206. The storage shell 206 is located inside the material tank 102. The bottom of the storage shell 206 is provided with a filter hole. The storage shell 206 is connected to a storage pipe 207. A solenoid valve is installed in the storage pipe 207. The storage pipe 207 passes through the material tank 102 and is used to discharge solid particles from the storage shell 206.

[0035] like Figure 3 , Figure 5 and Figure 6As shown, the anti-clogging component 3 includes circumferentially and equally spaced fixed shells 301, all of which are fixedly connected to and pass through the first flexible hose 107. Each fixed shell 301 is slidably connected to an air outlet shell 302, which has circumferentially distributed air outlets for blowing away accumulated fly ash. A U-shaped block 303 is rotatably connected to each fixed shell 301, and the U-shaped block 303 has a square groove. A first fixed rod 304 is fixedly connected to the air outlet shell 302. A fixed rod 304 engages with an adjacent U-shaped block 303 for limiting. The first fixed rod 304 passes through a square groove on the adjacent U-shaped block 303. When the U-shaped block 303 rotates, it drives the adjacent first fixed rod 304 to move through the square groove. A sliding block 305 is slidably connected to the fixed shell 301. The sliding block 305 consists of two semicircular rings, two semi-circular truncated cones, and one circular ring. The two semi-circular truncated cones are located in the middle of the two semicircular rings and the circular ring, and there is a gap between the two semicircular rings. There is a gap between the two semicircular truncated cones. The radius of the arc of the semicircular truncated cone gradually decreases from the semicircular ring to the circular ring. The sliding block 305 is in a limiting engagement with the adjacent U-shaped block 303. When the U-shaped block 303 contacts the semicircular ring on the adjacent sliding block 305, the U-shaped block 303 is fixed under the limiting of the sliding block 305. The sliding block 305 is fixedly connected to the limiting hook 306. The sliding block 305 contacts the second flexible hose 108. The limiting hook 306 is in a limiting engagement with the adjacent air outlet shell 302. The air outlet shell 302 is open. There is a sliding groove, and the limiting hook 306 slides in the sliding groove of the adjacent air outlet shell 302. The sliding block 305 is fixedly connected to the adjacent fixed shell 301 with an elastic element 307, which is a spring. The air outlet pipe of the suction component 104 is connected to the second hose 108 and passes through the second hose 108 to connect with the outside, so that the air blown out by the suction component 104 enters between the second hose 108 and the first hose 107 through the air outlet pipe, so that there is wind pressure in the second hose 108 and the first hose 107.

[0036] like Figures 7-9As shown, the feeding mechanism 4 includes a fixed ring 401, which is fixedly connected to the lower side of the material tank 102. A first baffle 402 is fixedly connected to the upper side of the fixed ring 401. The first baffle 402 has a V-shaped opening with an angle of less than 120 degrees. The first baffle 402 is rotatably connected to a rotating shaft 403. A feeding disc 404 is fixedly connected to the rotating shaft 403. The feeding disc 404 is composed of circumferentially distributed square blocks and is rotatably connected to the inner ring of the fixed ring 401. A second baffle 405 is fixedly connected to the lower side of the fixed ring 401. The second baffle 405 has a V-shaped opening with an angle of less than 120 degrees and is rotatably connected to the rotating shaft 403. The upper side of the feeding disc 404 is sealed and rotatably connected to the first baffle 402, and the lower side of the feeding disc 404 is sealed and rotatably connected to the second baffle 405. The opening direction of the V-shaped opening on the first baffle 402 is opposite to the opening direction of the V-shaped opening on the second baffle 405. The fixing ring 401 is fixedly connected to the second motor 406. The output shaft of the second motor 406 is driven by the pulley belt to the rotating shaft 403. When the second motor 406 starts, the output shaft of the second motor 406 drives the rotating shaft 403 to rotate through the pulley belt. The second baffle 405 is fixedly connected to and connected to the discharge shell 407. The upper side of the discharge shell 407 is larger than the V-shaped opening on the second baffle 405.

[0037] like Figure 8 and Figure 9 As shown, a first rubber wheel 5 is fixedly connected to the lower side of the rotating shaft 403. A first fixing member 501 distributed circumferentially is fixedly connected to the discharge shell 407. The first fixing member 501 is U-shaped. A pipe 502 is fixedly connected to the lower side of the first fixing members 501 distributed circumferentially. A second rubber wheel 503 is rotatably connected to the upper side of the pipe 502. The second rubber wheel 503 is located between the first fixing members 501 distributed circumferentially. The upper side of the second rubber wheel 503 is rotatably connected to the discharge shell 407. A circular through hole is opened inside the second rubber wheel 503. A third auger 504 is fixedly connected to the circular through hole inside the second rubber wheel 503. The third auger 504 is used to push the fly ash in the discharge shell 407 to the bottom of the second rubber wheel 503. The second rubber wheel 503 and the first rubber wheel 5 are in a transmission cooperation. When the rotating shaft 403 drives the first rubber wheel 5 to rotate, the first rubber wheel 5 drives the second rubber wheel 503 to rotate. A third hose 505 is fixedly connected to and connected to the pipe 502.

[0038] like Figure 7 and Figure 10As shown, a fixed rod 6 is fixedly connected to the rotating shaft 403. A T-shaped block 601 is rotatably connected to the fixed rod 6. A torsion spring is provided between the T-shaped block 601 and the fixed rod 6 to reset the scraper 603. Two symmetrically distributed elastic telescopic rods 602 are fixedly connected to the T-shaped block 601. A scraper 603 is fixedly connected to the T-shaped block 601. The scraper 603 is made of soft material, allowing it to deform during rotation, thus ensuring continuous contact between the scraper 603 and the material conveying tank 10. The inner wall of the conveying tank 102 is in contact with the scraper 603, which is fixedly connected to two symmetrically distributed elastic telescopic rods 602. The scraper 603 is in contact with the inner wall of the conveying tank 102. The conveying tank 102 is fixedly connected to the limiting pin 7, which cooperates with the scraper 603. When the scraper 603 contacts the limiting pin 7, the scraper 603 strikes the limiting pin 7 to generate vibration, which shakes off the fly ash around the scraper 603 and the conveying tank 102, reducing the residue of fly ash on the inner wall of the conveying tank 102.

[0039] When using this device to transport fly ash, the operator turns on the suction fan inside the suction unit 104 and starts the first motor 201. The output shaft of the first motor 201 drives the first auger 202 to rotate, and the first auger 202 drives the second auger 204 to rotate. The suction fan draws air into the first suction pipe 103. The drawn air passes through the outlet pipe between the first hose 107 and the second hose 108 and is discharged to the outside. A negative pressure is generated in the first suction pipe 103. The air in the conveying tank 102 enters the first suction pipe 103 through the filter bag 105. A negative pressure is generated in the conveying tank 102, causing the outside air to enter the conveying tank 102 through the bend pipe 106 and the first hose 107. The first hose 107 generates suction. At this time, the operator places the opening of the first hose 107 into the fly ash pile. The fly ash is drawn into the first hose 107 by the suction force. The fly ash then enters the bend pipe 106 along the first hose 107.

[0040] The fly ash entering the bend 106 first contacts the second auger 204 and moves upward under the rotation of the second auger 204. Simultaneously, air flows upward through the filter holes on the second auger 204, carrying the fly ash on the second auger 204 upward. Most of the upward-moving fly ash enters the conveying hopper 102 through the annular channel between the bend 106 and the straight pipe 203, while a small portion enters the straight pipe 203. The fly ash entering the conveying hopper 102... The ash moves upward and is blocked by the filter bag 105, located on the outside of the filter bag 105. The fly ash on the outside of the filter bag 105 falls downward under the action of gravity, causing the fly ash to move into the conveying tank 102. The dust entering the straight pipe 203 moves upward through the first auger 202 and enters the storage shell 206 through the discharge pipe 205. The dust entering the storage shell 206 is discharged through the filter hole at the bottom of the storage shell 206 and enters the conveying tank 102.

[0041] When fly ash becomes damp and produces large solid particles, these particles enter the bend in the pipe 106 through the first hose 107 and fall onto the second auger 204. The upward-moving airflow through the filter holes of the second auger 204 cannot blow the solid particles away. At this time, the solid particles move upward under the rotation of the second auger 204. The upward-moving solid particles move to the first auger 202 and move upward under its drive. The upward-moving solid particles enter the storage shell 206 through the discharge pipe 205, separating the solid particles. When the feeding is completed or the storage shell 206 is filled with solid particles, the operator opens the solenoid valve in the storage pipe 207, and the solid particles in the storage shell 206 are discharged through the storage pipe 207. After the solid particles in the storage shell 206 are discharged, the solenoid valve in the storage pipe 207 is closed.

[0042] By cooperating with the suction component 104, the first screw conveyor 202 and the second screw conveyor 204, any solid particles that may be present in the fly ash are lifted up, preventing solid particles from depositing below the bend 106 and causing blockage of the bend 106.

[0043] During the movement of fly ash within the first flexible hose 107, the fly ash continuously gathers and moves under the action of suction. When a large amount of fly ash accumulates within the first flexible hose 107, the accumulated fly ash settles into the first flexible hose 107 and is squeezed together by gravity, making it difficult for the accumulated fly ash to separate under the action of wind. This hinders the subsequent flow of fly ash and may accumulate more and more, eventually causing the first flexible hose 107 to become blocked.

[0044] When fly ash accumulates inside the first hose 107, the first hose 107 presses downward against the fixed shell 301. Taking a fixed shell 301 and its internal parts on the lower side of the first hose 107 as an example, the fixed shell 301 moves downward, the sliding block 305 remains in the same position under the limit of the first hose 107, and the sliding block 305 moves upward relative to the fixed shell 301. The upward movement of the sliding block 305 compresses the elastic element 307. During the upward sliding process of the sliding block 305 inside the fixed shell 301, the sliding block 305 gradually contacts the air outlet shell 302, and the limiting hook 306... Sliding within the air outlet housing 302, when the sliding block 305 contacts the air outlet housing 302, the lower end of the U-shaped block 303 corresponds to the side of the upper semicircular platform of the sliding block 305, and the restriction on the U-shaped block 303 is released. The sliding block 305 continues to move, and the sliding block 305 squeezes the air outlet housing 302 to move upward. The air outlet housing 302 drives the first fixed rod 304 to move upward. The first fixed rod 304 squeezes the U-shaped block 303, causing the U-shaped block 303 to rotate. The first fixed rod 304 slides within the U-shaped block 303, and the air outlet housing 302 moves upward along the fixed housing 301.

[0045] When the air outlet shell 302 moves upward into the first hose 107, it squeezes the fly ash accumulated inside the first hose 107, disrupting the integrity of the accumulated fly ash. Under the negative pressure inside the first hose 107 and the positive pressure between the first hose 107 and the second hose 108, air enters the air outlet shell 302 through the sliding block 305 and is discharged from the air outlet hole on the air outlet shell 302. The air discharged from the air outlet hole on the air outlet shell 302 blows the fly ash accumulated on the first hose 107, dispersing the fly ash. After the fly ash is dispersed, the gravity on the first hose 107 decreases, the compressive force on the fixed shell 301 decreases, and finally the compressive force on the elastic element 307 decreases. The elastic element 307 is released and drives the sliding block 305 to move downward relative to the fixed shell 301.

[0046] During the downward movement of the sliding block 305 relative to the fixed shell 301, the sliding block 305 drives the limiting hook 306 to slide within the air outlet shell 302. When the limiting hook 306 contacts the edge of the groove within the air outlet shell 302, the limiting hook 306 drives the air outlet shell 302 to move downward. When the U-shaped block 303 contacts the side of the upper semicircular platform of the sliding block 305, the sliding block 305 continues to move downward, squeezing the U-shaped block 303. The U-shaped block 303 rotates and, through the first fixed rod 304, drives the air outlet shell 302 to move downward. When the U-shaped block 303 disengages from the side of the upper semicircular platform of the sliding block 305, the air outlet shell 302 completely enters the fixed shell 301. The movement of the air outlet shell 302 prevents the accumulation of fly ash in the first hose 107. After fly ash accumulates, the movement of the lower side of the air outlet shell 302 at the point of fly ash accumulation prevents the accumulation of fly ash in the first hose 107. The fly ash accumulated inside the first hose 107 is compressed, disrupting the integrity of the accumulated fly ash and reducing the accumulation of fly ash inside the first hose 107. By introducing outside air into the first hose 107 through the air outlet shell 302, the accumulated fly ash is dispersed, further reducing the accumulation of fly ash inside the first hose 107. During the compression of the elastic element 307, the U-shaped block 303 and the sliding block 305 move towards each other. The air outlet shell 302 only moves when the edge of the semi-circular frustum of the U-shaped block 303 and the sliding block 305 contacts, preventing the elastic element 307 from being subjected to small external forces. However, when no accumulation occurs inside the first hose 107, the sliding block 305 drives the air outlet shell 302 to move, making the air outlet shell 302 connected to the inside of the first hose 107. This leads to the inner wall of the first hose 107 being connected to the outside, reducing the suction force inside the first hose 107.

[0047] After the fly ash accumulates in the conveying tank 102 for a period of time, the operator starts the second motor 406. The second motor 406 drives the rotating shaft 403 to rotate, which in turn drives the feeding disc 404 and the first rubber wheel 5 to rotate. The fly ash enters the feeding disc 404 through the notch on the first baffle 402 and is then discharged through the notch on the second baffle 405. The fly ash discharged from the second baffle 405 enters the discharge shell 407, causing the fly ash to fall continuously. Simultaneously, because the V-shaped openings of the first baffle 402 and the second baffle 405 are relatively small (the opening of the V-shape of the first baffle 402 faces left and the opening of the V-shape of the second baffle 405 faces right), the square plates of the feeding disc 404 are densely arranged. As the square plates on the feeding disc 404 rotate the fly ash, the front of the fixing ring 401 always has two adjacent square plates forming a sealed cavity with the first baffle 402 and the second baffle 405. Located at the rear of the fixed ring 401, there are always two adjacent square plates forming a sealed cavity with the first baffle 402 and the second baffle 405. Through the two sealed cavities, the openings of the first baffle 402 and the second baffle 405 are always isolated, thus preventing the interior of the conveying tank 102 from communicating with the outside world. This prevents wind from entering from the bottom of the conveying tank 102, which would prevent the fly ash inside the conveying tank 102 from settling. At the same time, the first rubber wheel 5 drives the third auger 504 to rotate through the second rubber wheel 503. The third auger 504 discharges the fly ash into the third hose 505. Even after the fly ash covers the discharge port below the third hose 505, the third auger 504 can still push the fly ash in the third hose 505 downwards. Because the accumulated fly ash covers the discharge port, the discharged fly ash compresses the fly ash accumulated below, thus stabilizing the discharged fly ash and reducing the fly ash from flying.

[0048] During the rotation of the rotating shaft 403, the rotating shaft 403 drives the fixed rod 6 to rotate, the fixed rod 6 drives the T-shaped block 601 to rotate, and the T-shaped block 601 drives the elastic telescopic rod 602 and the scraper 603 to rotate. As the fly ash settles within the conveying tank 102, it randomly settles on the inner wall of the conveying tank 102. The fly ash on the side wall of the conveying tank 102 accumulates and then slides downwards. When the fly ash on the side wall contacts the fly ash on the lower side, it provides support to the fly ash on the side wall, ensuring that there is still a large amount of fly ash on the side wall of the conveying tank 102. During the rotation of the scraper 603, the scraper 603 scrapes off the fly ash on the side wall. At the same time, the fly ash on the upper side of the scraper 603, lacking support, slides downwards, reducing... The fly ash adhering to the conveying tank 102 is dislodged during the rotation of the scraper 603. When the scraper 603 contacts the limiting pin 7, the scraper 603 strikes the limiting pin 7, generating vibration that shakes off the fly ash around the scraper 603 and the conveying tank 102, reducing the amount of fly ash remaining on the inner wall of the conveying tank 102. Under the obstruction of the limiting pin 7, the scraper 603 rotates around the center point of the fixed rod 6. The torsion spring stores force, and the scraper 603 bends inward under the obstruction of the conveying tank 102. The elastic telescopic rod 602 retracts. After the limiting pin 7 loses contact with the scraper 603, the scraper 603 returns to its original position under the action of the torsion spring. Under the compression of the elastic telescopic rod 602, the scraper 603 straightens and adheres to the conveying tank 102, and the elastic telescopic rod 602 returns to its original position.

[0049] After transportation is completed, the staff turns off the suction unit 104 and the first motor 201. After the material is discharged from the material tank 102, the staff turns off the second motor 406.

[0050] Example 2: Based on Example 1, such as Figure 11 and Figure 12As shown, it also includes a suction mechanism 8 for sucking fly ash into the first hose 107. The suction mechanism 8 is located at the left end of the second hose 108. The suction mechanism 8 includes a handle 801, which is slidably connected to the second hose 108. The handle 801 is fixedly connected to a second fixing member 802, which consists of a straight rod and a square plate at the left end of the straight rod. Four circumferentially distributed second fixing rods 803 are fixedly connected to the left side of the second hose 108. The second fixing member 802 is slidably connected to two adjacent second fixing rods 803 on the upper side. The lower sides of the two second fixing rods 803 on the lower side are fixedly connected to brackets. Four circumferentially distributed limiting plates 804 are fixedly connected to the first hose 107. The four circumferentially distributed limiting plates 804 are located in the circumferential distribution... The four second fixing rods 803 form the inside of an annular ring. The limiting plate 804 is slidably connected to the moving ring 805. The moving ring 805 cooperates with the second fixing member 802. When the second fixing member 802 moves to the left, the second fixing member 802 contacts the moving ring 805 and continues to move, driving the moving ring 805 to move to the left. The moving ring 805 is slidably connected to the circumferentially distributed second fixing rods 803. The circumferentially distributed limiting plates 804 are jointly fixed to the fixing plate 806. The fixing plate 806 and the moving ring 805 are fixedly connected to the sealing cloth 807. The moving ring 805 and the second hose 108 are fixedly connected to the sealing cloth 807. The sealing cloth 807 is located between the four circumferentially distributed second fixing rods 803 and the four circumferentially distributed limiting plates 804.

[0051] like Figures 12-14 As shown, a first flexible hose 107 is fixedly connected to a fixing block 901. A limiting rod 902 is fixedly connected to the middle of the fixing block 901. A moving ring 805 is fixedly connected to and passes through four circumferentially distributed second suction pipes 903. The limiting rod 902 is slidably connected to a limiting component 904 and an elastic disc 905. The limiting component 904 consists of a circular plate and four square plates. The elastic disc 905 is located to the right of the limiting component 904 and consists of four arc-shaped elastic plates. The limiting component 904 is fixedly connected to the elastic disc 905. The limiting component 904 is fixedly connected to the moving ring 805 through the circular plate on it. The elastic disc 905 is fixedly connected to the circumferentially distributed second suction pipes 903. The four circumferentially distributed limiting posts 906 are all in cooperation with the limiting rods 902. When the elastic disc 905 bends, the limiting posts 906 on the elastic disc 905 move towards the limiting rods 902. When the limiting posts 906 contact the limiting rods 902, the limiting rods 902 restrict the movement of the limiting posts 906 under the action of friction. The four circumferentially distributed second suction pipes 903 are all provided with four circumferentially distributed slots. A third rotating rod 907 is rotatably connected in each of the circumferentially distributed slots of the second suction pipes 903. The third rotating rod 907 is used to move the fly ash during material suction.

[0052] During the process of drawing fly ash into the first hose 107, the angle and position of the opening of the first hose 107 need to be adjusted manually. When the cooled fly ash is located below the boiler, due to the narrow space under the boiler, it is difficult for workers to change the opening position of the first hose 107. Automatic suction is achieved by sliding the moving ring 805. The specific operation is as follows: The operator first inserts the second fixing rod 803 into the fly ash section below the boiler, starts the suction device 104, and then pushes the handle 801 to the left. The handle 801 drives the second fixing part 802 to the left. When the second fixing part 802 contacts the moving ring 805... The second fixing member 802 continues to move to the left, which drives the moving ring 805 to move to the left. When the moving ring 805 moves to the left end of the second fixing rod 803, the operator begins to move the handle 801 to the right to reset it. The handle 801 drives the second fixing member 802 to the right to reset it. When the left side of the second fixing member 802 contacts the second hose 108, it stops. At the same time, fly ash is sucked in from the second suction pipe 903. During the process of sucking in fly ash from the second suction pipe 903, the wind drives the third rotating rod 907 on the second suction pipe 903 to rotate. During the rotation of the third rotating rod 907, the deposited fly ash is stirred up, improving the suction efficiency.

[0053] During the process of drawing in fly ash through the second suction pipe 903, taking the lower second suction pipe 903 as an example, the fly ash entering the second suction pipe 903 is guided by the limiting member 904 and passes through the lower part of the lower elastic disc 905, squeezing the elastic disc 905. The lower part of the elastic disc 905 is squeezed and bent. The elastic disc 905 drives the lower limiting post 906 to approach the limiting rod 902 and contact the limiting rod 902. After the limiting post 906 contacts the limiting rod 902, the limiting post 906 remains stationary under the action of friction. When there is no fly ash under the lower part of the lower second suction pipe 903, the second suction pipe 903 draws in air. However, the airflow speed is faster than that of fly ash. At this time, the lower part of the elastic disc 905 is subjected to a small force, which is enough to make the elastic disc 905 move. When the air pressure on both sides of 05 is balanced, the force on the elastic disc 905 decreases, causing the lower part of the elastic disc 905 to reset slightly. The limiting post 906 disengages from the limiting rod 902. When all four limiting posts 906 disengage from the limiting rod 902, the limiting member 904 moves to the right under the suction of the first hose 107. The sealing cloth 807 on the right side of the moving ring 805 wrinkles and gathers, while the sealing cloth 807 on the left side of the moving ring 805 extends. During the movement of the limiting member 904 to the right, when a second suction pipe 903 sucks in fly ash, the limiting member 904 immediately stops moving. After the fly ash outside the second suction pipe 903 is completely sucked in, the limiting member 904 continues to move, preventing fly ash from being left behind and saving manpower from constantly adjusting the first hose 107.

[0054] When there is no fly ash in the second suction pipe 903 on one side, taking the upper second suction pipe 903 as an example, there is no fly ash on the outside of the upper second suction pipe 903, but there is fly ash on the outside of the front, rear, and lower second suction pipes 903. The front, rear, and lower second suction pipes 903 draw in fly ash, which then passes through the front, rear, and lower sides of the elastic disc 905. Because the mass of fly ash is greater than that of air, the front, rear, and lower sides of the elastic disc 905 are compressed by the fly ash and air, causing the elastic disc 905 to... The large deformation on the sides and the large openings on the front, rear, and bottom sides of the elastic disc 905 allow more air to pass through. The second suction pipe 903 on the upper side is free of fly ash, so the upper side of the elastic disc 905 is only compressed by the wind. The deformation of the upper side of the elastic disc 905 is smaller than that on the front, rear, and bottom sides, allowing more air to pass through the second suction pipes 903 on the front, rear, and bottom sides, increasing the suction force of the second suction pipes 903 on the front, rear, and bottom sides, and improving the efficiency of fly ash extraction.

[0055] When the moving ring 805 moves to contact the second fixing part 802, the worker moves the second fixing rod 803. The four second fixing rods 803 drive the parts between them to move to other locations where fly ash exists. At the same time, the worker moves the moving ring 805 to the left end of the second fixing rod 803 again by moving the handle 801 to continue sucking up fly ash until all fly ash is transported. After the fly ash is transported, the worker turns off the suction part 104 to complete the cleaning.
