Description

Technical Field

[0001] This invention belongs to the field of municipal road waste treatment technology, specifically a rapid degradation composting device for municipal road waste. Background Technology

[0002] Municipal road waste refers to various types of waste generated on urban roads and in adjacent public areas. Its sources are wide-ranging and its composition complex, directly impacting road traffic efficiency, urban appearance, and citizens' travel experience. Municipal road waste includes household waste, commercial waste, construction waste and engineering waste, green space maintenance waste, and other special waste. A rapid degradation composting device is a device that accelerates the decomposition of organic waste into mature organic fertilizer. It utilizes a fermentation chamber, mixing system, and ventilation and temperature control system to process organic waste and other materials for resource recovery. Since municipal road waste includes organic waste, a rapid degradation composting device for municipal road waste is needed, specifically designed to quickly convert organic components such as fallen leaves, fruit peels, paper scraps, and kitchen waste from road sweeping into mature organic fertilizer.

[0003] Existing rapid degradation composting devices for municipal road waste typically involve directly collecting and storing municipal road waste, then mixing it using several mixing structures, and finally introducing gas through ventilation pipes on the side walls of the device. However, during operation, the waste gradually compacts during mixing, reducing porosity and preventing oxygen from penetrating into the accumulated waste. Furthermore, uneven distribution of waste within the device often creates localized anoxic zones. Microorganisms in these zones are forced to undergo anaerobic metabolism, producing organic acids, alcohols, and other substances. This not only reduces composting efficiency but also generates foul odors, thus lowering the overall degradation and composting efficiency of the rapid degradation composting device and severely impacting compost quality, failing to meet public demand. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art; to this end, the present invention proposes a rapid degradation composting device for municipal road waste.

[0005] A rapid degradation composting device for municipal road waste includes: a composting bin and a composting mechanism mounted on the composting bin; a leachate collection tank is installed at the bottom of the composting bin for discharging leachate generated during composting, and a drain pipe connected to the leachate collection tank is provided on one side of the composting bin; before the municipal road waste is transported to the composting bin, the moisture content of the waste needs to be controlled to meet the requirements for composting degradation, and waste that cannot be composted is screened out; the composting bin has a composting chamber for storing municipal road waste, and the composting bin has a door for sealing the composting chamber; the composting mechanism includes several stirring structures rotatably mounted in the composting chamber and a device mounted on the composting bin that works in conjunction with the stirring structures. The ventilation assembly used in conjunction with the composting chamber provides hot air for the rapid degradation and composting of municipal road waste. The stirring structure includes several rotating tubes rotatably disposed inside the composting chamber and several stirring paddles disposed on the rotating tubes to stir the municipal road waste. A stirring motor for controlling the rotation of the rotating tubes is installed at the top of the composting chamber. The stirring structure also includes several spiral sleeves disposed on one side of the stirring paddles and first spiral blades fixed on the spiral sleeves. The spiral sleeves are coaxially mounted on the rotating tubes, and the spiral sleeves and stirring paddles on adjacent rotating tubes are staggered. The staggered arrangement of adjacent stirring structures enables all-round stirring of the municipal road waste inside the composting chamber.

[0006] As a further aspect of the present invention: the ventilation assembly includes a heating pipe detachably disposed on the outside of the compost bin, a filter box detachably connected to the heating pipe, and a first connector installed on the other side of the filter box.

A solenoid valve is installed on each of the second air guides, and the upper end of each second air guide is connected to a second connector. A ventilation groove communicating with the second connector is formed in the rotating pipe. The heating pipe guides hot air into the ventilation groove inside the rotating pipe through the cooperation of the main ventilation pipe and the secondary ventilation pipe. The ventilation assembly also includes several ventilation holes inclinedly formed on the rotating pipe and the spiral sleeve.

Under the action of centrifugal force, the second spiral blade of the cleaning rod is in close contact with the inner wall of the ventilation holes, forming a scraping action. At the same time, the rotation of the rotating tube causes the cleaning rod to move axially, thereby realizing continuous cleaning of the ventilation holes. As a further aspect of the present invention: the cleaning assembly further includes a filter screen disposed on the support block and a scraper strip attached to the filter surface of the filter screen.

A second transmission rod is coaxially disposed on the first rotating gear. The bottom end of the second transmission rod extends out of the protective box and is provided with a first universal joint that is pulverizedly connected to the first transmission rod. When the first rotating gear rotates, the second transmission rod controls the bevel gear structure to rotate through the first universal joint and the first transmission rod, thereby controlling the second spiral blades to clean the ventilation holes through the cleaning rod.

[0012] As a further aspect of the present invention: a rotating rod is vertically provided at the center of the ventilation slot and coaxially connected to the rotating frame. The top end of the rotating rod passes through the rotating tube and is connected to the stirring motor. When the stirring motor is working, the rotating rod drives several first rotating gears to rotate through the rotating frame and the transmission external gear ring. The rotating frame includes a fixed ring provided on the rotating rod, a connecting ring that rotates in contact with the inner wall of the protective box, and a fixed rod arranged in a circular array and connecting the fixed ring and the connecting ring. The outer wall of the connecting ring is provided with several reinforcing blocks that are connected to the transmission external gear ring.

[0013] As a further aspect of the present invention: the cleaning assembly further includes a rotating component rotatably disposed on the inner top surface of the composting chamber and connected to the top end of the rotating tube. The top end of the rotating component has a rotating groove. The inner top surface of the composting chamber is rotatably provided with a second rotating gear and a transmission gear meshing with the second rotating gear via an mounting block. The second rotating gear is provided with a coupling rod connected to the output shaft of the stirring motor. The top end of the rotating rod extends into the rotating groove and is connected to the second rotating gear. The inner wall of the rotating groove is equipped with a transmission internal gear ring meshing with the transmission gear. The stirring motor controls the rotating rod to rotate through the second rotating gear, and controls the transmission internal gear ring to rotate through the second rotating gear and the transmission gear, thereby controlling the rotation of the rotating tube through the rotating component.

[0014] As a further aspect of the present invention: the composting mechanism further includes a sealing assembly disposed on the rotating tube and the spiral sleeve to seal the ventilation holes. The sealing assembly includes a first sealing block movably disposed in the spiral sleeve and a screw drive structure cooperating with the first sealing block. The first sealing block is disposed in a region of the ventilation hole that has an oblique elongated structure. The spiral sleeve has a first sealing groove that fits against the first sealing block. The first sealing groove is disposed on the lower side of the ventilation hole and communicates with the ventilation hole. The screw drive structure is disposed on the outer side of the first sealing block. The screw drive structure has a second connecting block that connects to the outer wall of the first sealing block. A sealing block that is aligned with the first sealing block is disposed on the upper side of the ventilation hole. The spiral sleeve has a sealing groove that fits with the sealing block. The sealing block is movably disposed in the sealing groove. The top and bottom ends of the first sealing block are both set as inclined surfaces. When the first sealing block is inserted into the sealing groove, it controls the movement of the sealing block within the sealing groove. The top of the first sealing block is flush with the inner bottom surface of the ventilation hole. The sealing assembly also includes a first guide rod disposed at the top of the sealing groove and inserted into the sealing block, and a return spring sleeved on the first guide rod. The top of the sealing block has a first guide hole that fits with the first guide rod. One side of the sealing block has a guide block.

[0015] As a further aspect of the present invention: the sealing assembly further includes a second guide rod vertically disposed on one side of the lead screw drive structure and inserted into the first sealing block; the bottom end of the first sealing block has a second guide hole matching the second guide rod, and a buffer spring connected to the second guide rod is disposed in the guide hole; the sealing assembly further includes a lifting block movably disposed in the ventilation slot and a lifting strip disposed on one side of the lifting block and guided by the rotating tube; the rotating tube has a lifting groove matching the lifting strip; the sealing assembly further includes a first lifting rack disposed on the other side of the lifting strip and a lifting gear meshing with the first lifting rack; one end of the lifting gear has a first lifting rack rotatably connected to the rotating tube. The first connecting rod has a second universal joint at its other end, and a third universal joint at the bottom of the screw drive structure. One end of the second universal joint is connected to a third drive rod, which is inclined and parallel to the ventilation hole. The sealing assembly also includes a second connecting rod vertically disposed on the outer side of the lifting block and a floating ball disposed at one end of the second connecting rod. The floating ball is hollow. When the lifting block moves downward, the lifting gear and the first lifting rack cooperate through the second universal joint, the third drive rod, the third universal joint, and the screw drive structure to control the first sealing block to move upward, thus sealing the ventilation hole.

[0016] As a further aspect of the present invention: the sealing assembly further includes a second lifting rack disposed on the other side of the lifting gear and meshing with the lifting gear, and a second sealing block connected to the second lifting rack. The rotating tube has a second sealing groove that fits against the second sealing block. The second sealing groove communicates with the ventilation hole. When gas is introduced into the ventilation slot, the floating ball causes the lifting block to move upward, thereby causing the lifting gear to control the second sealing block to move downward. The lifting gear and the lead screw transmission structure control the first sealing block to move downward, opening the ventilation hole. When gas is not introduced into the ventilation slot, the lifting block moves downward under the action of gravity, and causes the first sealing block and the second sealing block to move upward, sealing the ventilation hole.

[0017] As a further embodiment of the present invention: the ventilation assembly further includes several exhaust hoods installed on the inner top surface of the composting chamber and exhaust branch pipes set at the top of the exhaust hoods. The top end of the exhaust branch pipes penetrates through the composting chamber. The ventilation assembly also includes an exhaust main pipe connected to the exhaust branch pipes. Several exhaust main pipes are respectively set on one side of the stirring motor. Several exhaust hoods are aligned. One end of the exhaust main pipe is connected to a gas purification device. The gas purification device is set as a chemical scrubbing tower, a bio-trickling filter tower or other purification device.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] (1) The present invention uses a composting box and composting mechanism, with rotating pipe, stirring paddle, stirring motor, spiral sleeve and first spiral blade working together. During the stirring process, the garbage can be fully turned over. The spiral pushing action of the first spiral blade can also reduce the accumulation and compression of garbage under gravity, effectively ensuring the porosity of the compost material and providing basic space conditions for oxygen infiltration and microbial metabolism. This fundamentally alleviates the problem of local hypoxia. The heating pipe, filter box, main ventilation pipe, first air guide pipe, secondary ventilation pipe, rotating pipe, ventilation slot and ventilation hole work together to make oxygen evenly penetrate into the material, avoid the formation of local hypoxia areas, and guide the material to turn over with the stirring action, further improving the gas-solid contact efficiency, significantly improving the composting degradation efficiency, improving the compost quality and improving the use effect of the degradation composting device.

[0020] (2) The present invention uses a cleaning component, a cleaning rod, a second spiral blade, a support block, a filter screen and a scraper to clean the ventilation holes. It also uses a stirring motor, a rotating component, a mounting block, a second rotating gear, a transmission gear, a transmission internal gear ring, a bevel gear structure, a first transmission rod, a first rotating gear, a second transmission rod, a rotating frame, a transmission external gear ring and a rotating rod to clean the ventilation holes. During the rotation of the rotating tube, the cleaning rod rotates synchronously with the rotating tube. Under the action of centrifugal force, the second spiral blade is pressed against the inner wall of the ventilation hole to form a scraping action, which performs continuous cleaning and completely removes the material impurities remaining in the ventilation holes. This further avoids the accumulation of impurities that block the ventilation channel and the filter screen, ensures the long-term stable operation of the ventilation system, ensures the effective operation of the ventilation component, and improves the use effect of the degradation composting device.

[0021] (3) The present invention achieves adaptive switching control of ventilation holes by using the sealing components, floating ball, lifting block, lifting bar, first lifting rack, lifting gear, second lifting rack and screw transmission structure. When the ventilation component supplies air, the floating ball drives the lifting block to move upward under the action of airflow. The transmission mechanism controls the first sealing block and the second sealing block to move synchronously, opening the ventilation hole to ensure hot air delivery. When the air supply stops, the lifting block resets under the action of gravity, driving the first sealing block and the second sealing block to seal the ventilation hole in both directions. This effectively prevents compost material or leachate from flowing back into the ventilation hole, avoids the blockage of the ventilation hole and damage to the cleaning components, extends the service life of the composting mechanism, reduces maintenance costs, and improves the use effect of the degradation composting device.

[0034] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] Please see Figure 1 - Figure 6This application provides a rapid degradation composting device for municipal road waste, including a composting bin 1 and a composting mechanism installed on the composting bin 1; a leachate collection tank is installed at the bottom of the composting bin 1 for discharging leachate generated during composting, and a drain pipe 58 connected to the leachate collection tank is provided on one side of the composting bin 1; before the municipal road waste is transported to the composting bin 1, the moisture content of the waste needs to be controlled to meet the requirements for composting degradation, and waste that cannot be composted is screened out and crushed; the composting bin 1 is provided with a composting chamber 2 for storing municipal road waste, and the composting mechanism needs to be inoculated with microorganisms during use. The composting mechanism also includes a heating structure for controlling the temperature of the waste and a spray structure for regulating the humidity of the waste. The heating structure can be a heating block or a heating wire, and the composting bin 1 is provided with a door to seal the composting chamber 2. The composting mechanism includes several stirring structures 3 rotatably arranged in the composting chamber 2 and a ventilation assembly arranged on the composting box 1 and used in conjunction with the stirring structures 3. The ventilation assembly can provide hot air to the composting chamber 2 for the rapid degradation and composting of municipal road waste. The stirring structure 3 includes several rotating pipes 4 rotatably arranged inside the composting chamber 2 and several stirring paddles 5 arranged on the rotating pipes 4 to stir the municipal road waste. The top of the composting box 1 is equipped with a stirring motor 6 for controlling the rotation of the rotating pipes 4. The stirring structure 3 also includes several spiral sleeves 7 arranged on one side of the stirring paddles 5 and first spiral blades 8 fixed on the spiral sleeves 7. The spiral sleeves 7 are coaxially mounted on the rotating pipes 4. The spiral sleeves 7 and stirring paddles 5 on adjacent rotating pipes 4 are staggered, and the adjacent stirring structures 3 are staggered, which can stir the municipal road waste inside the composting chamber 2 in all directions.

[0037] In this embodiment, the collected municipal road waste is screened to remove non-degradable compostable waste, including construction waste, plastic and rubber products, metal and glass, or other hazardous waste. The moisture content of the waste is then controlled, and the qualified municipal road waste is transported to the composting chamber 2 in the composting bin 1 for decomposition and composting. The stirring structure 3 is controlled to stir the municipal road waste. The stirring motor 6 is started, driving the rotating pipe 4 to rotate, which in turn drives the stirring paddle 5 to mix the waste. The rotating pipe 4 also drives the spiral sleeve 7 to rotate, which in turn drives the first spiral blade 8 to rotate, causing the first spiral blade 8 to control the upward transport of the waste, thereby ensuring thorough mixing.

[0038] The ventilation assembly of this invention includes a heating pipe 63 detachably disposed on the outside of the compost bin 1, a filter box 9 detachably connected to the heating pipe 63, and a first connector 10 installed on the other side of the filter box 9. One end of the heating pipe 63 is connected to a gas supply device, and the heating pipe 63 can heat the gas supplied by the gas supply device and preheat the transported gas. Several filter plates for filtering the gas are installed in the filter box 9. The ventilation assembly also includes a main ventilation pipe 11 connected to the first connector 10, several first air guide pipes 12 connected to the main ventilation pipe 11, and secondary ventilation pipes 13 connected to the first air guide pipes 12. One end of the secondary ventilation pipes 13 extends into the interior of the compost bin 1, and the secondary ventilation pipes 13 are respectively aligned with the rotating pipe 4.

[0039] In this embodiment, the heating tube 63 preheats the gas and delivers the preheated gas to the filter box 9, so that the filter plate filters impurities from the gas and prevents impurities from entering the rotating tube 4. The filtered gas enters the main ventilation tube 11 through the first connector 10, and the main ventilation tube 11 guides the gas into several secondary ventilation tubes 13 respectively.

[0040] The ventilation assembly of this invention also includes several second connectors 15 disposed on the bottom inner side of the composting chamber 2 and rotatably connected to the bottom end of the rotating pipe 4, and several second air guides 16 vertically disposed on the upper end of the secondary ventilation pipe 13. A solenoid valve 14 is installed on each of the second air guides 16, and the upper end of the second air guide 16 is connected to the second connectors 15. A ventilation groove 17 connected to the second connectors 15 is opened in the rotating pipe 4. The heating pipe 63 guides hot air into the ventilation groove 17 inside the rotating pipe 4 through the cooperation of the main ventilation pipe 11 and the secondary ventilation pipe 13. The ventilation assembly also includes several ventilation holes 18 inclinedly opened on the rotating pipe 4 and the spiral sleeve 7. The inner walls of the ventilation groove 17 and the ventilation holes 18 are designed to be non-stick. The ventilation groove 17 is connected to the ventilation holes 18, enabling the introduction of hot air into municipal road waste to assist in the rapid degradation of municipal road waste.

[0041] In this embodiment, when the solenoid valve 14 opens the second air duct 16, the gas in the secondary ventilation duct 13 enters the second connector 15 through the second air duct 16, and then enters the ventilation groove 17 inside the rotating pipe 4 through the second connector 15. The ventilation groove 17 introduces the gas into the garbage through several ventilation holes 18, so that the garbage is in full contact with oxygen, and the oxygen concentration in the composting chamber 2 reaches the oxygen range required by aerobic microorganisms in the garbage degradation composting process.

[0042] In this invention, the ventilation hole 18 has a round hole structure at one end near the ventilation slot 17, and an oblique elongated structure at the other end. The edge of the hole is chamfered. The oblique design is conducive to the directional distribution of airflow, which can form a more uniform oxygen supply during composting. The tilt angle of the ventilation hole 18 is set to 30°-45°, so that the airflow can form the best diffusion effect, while avoiding material stagnation in the channel. The chamfered design of the edge of the hole can not only reduce material adhesion, but also guide the direction of airflow and enhance the aeration effect. The tilt direction of the ventilation hole 18 is the same as the rotation direction of the first spiral blade 8, both upward.

[0043] In this embodiment, when the ventilation slot 17 and the ventilation hole 18 work together to provide oxygen, the rotating pipe 4 drives the ventilation hole 18 to rotate, thereby adjusting the oxygen inlet point and allowing the ventilation hole 18 to introduce oxygen into the garbage in different areas.

[0044] The ventilation assembly of this invention also includes several exhaust hoods 55 installed on the inner top surface of the composting chamber 2 and exhaust branch pipes 56 set at the top of the exhaust hoods 55. Several oxygen sensors are provided in the composting chamber 2 to detect the oxygen content. The top of the exhaust branch pipe 56 penetrates through the composting box 1. The ventilation assembly also includes an exhaust main pipe 57 connected to the exhaust branch pipes 56. Several exhaust main pipes 57 are respectively set on one side of the stirring motor 6. Several exhaust hoods 55 are aligned. One end of the exhaust main pipe 57 is connected to a gas purification device through an exhaust device. The gas purification device is set as a chemical scrubbing tower, a bio-trickling filter tower or other purification device.

[0045] In this embodiment, when it is necessary to discharge the gas inside the composting chamber 2, the exhaust device is activated, so that the air inside the composting chamber 2 enters the exhaust hood 55 and then enters the exhaust branch pipe 56 through the exhaust hood 55. The exhaust branch pipe 56 guides the air into the exhaust main pipe 57 and guides the discharged air into the gas purification device for purification treatment. After purification, the air is tested and discharged into the air after meeting the standards.

[0046] Example 2

[0047] Based on Example 1, referring to Figure 4 - Figure 9This is the second embodiment of the invention. In this embodiment, the composting mechanism further includes a cleaning component mounted on the rotating tube 4 to clean the ventilation holes 18. The cleaning component includes a cleaning rod 19 movably mounted in the ventilation holes 18 and a second spiral blade 20 mounted on the cleaning rod 19. The second spiral blade 20 is in contact with the inner wall of the ventilation holes 18. A support block 21, rotatably connected to the cleaning rod 19, is vertically mounted in the ventilation holes 18. One end of the cleaning rod 19 is vertically connected to the support block 21. When the rotating tube 4 rotates, the cleaning rod 19 and the second spiral blade 20 rotate together with the rotating tube 4. Under centrifugal force, the second spiral blade 20 of the cleaning rod 19 is tightly... The cleaning rod 19 moves axially along the inner wall of the ventilation hole 18, while the rotation of the rotating tube 4 causes the cleaning rod 19 to move axially, thus achieving continuous cleaning of the ventilation hole 18. The cleaning assembly also includes a filter screen 22 mounted on the support block 21 and a scraper 23 attached to the filter surface of the filter screen 22. The scraper 23 is mounted on the cleaning rod 19 via a first connecting block. The filter screen 22 has through holes that match the cleaning rod 19. One end of the second spiral blade 20 is close to the filter screen 22, so that when the cleaning rod 19 rotates, the scraper 23 cleans the impurities on the filter screen 22, and the second spiral blade 20 cleans the impurities at the filter screen 22.

[0048] In this embodiment, the cleaning rod 19 is controlled to rotate, which causes the second spiral blade 20 to rotate, so that the second spiral blade 20 cleans the ventilation hole 18. The rotation of the cleaning rod 19 causes the first connecting block to rotate, which in turn causes the scraper 23 to rotate, so that the scraper 23 scrapes and cleans the filter screen 22, and the second spiral blade 20 transports the cleaned impurities and discharges them from the ventilation hole 18.

[0049] The cleaning assembly of this invention also includes a bevel gear structure 24 rotatably disposed inside the support block 21 and a first transmission rod 25 coaxially connected to the bevel gear structure 24. One end of the first transmission rod 25 passes through the rotating tube 4 and extends into the interior of the ventilation slot 17. One end of the cleaning rod 19 is coaxially connected to the other end of the bevel gear structure 24. The cleaning assembly also includes several protective boxes 64 fixedly installed on the inner wall of the ventilation slot 17 and a first rotating gear 26 rotatably disposed inside the protective box 64. A second transmission rod 27 is coaxially disposed on the first rotating gear 26. The bottom end of the second transmission rod 27 extends out of the protective box 64 and is provided with a first universal joint 65 that is connected to the first transmission rod 25. When the first rotating gear 26 rotates, the second transmission rod 27 controls the bevel gear structure 24 to rotate through the first universal joint 65 and the first transmission rod 25, thereby controlling the second spiral blade 20 to clean the ventilation hole 18 through the cleaning rod 19.

[0050] In this embodiment, when the first rotating gear 26 rotates inside the protective box 64, it causes the second transmission rod 27 to rotate, the second transmission rod 27 to rotate the first universal joint 65, the first universal joint 65 to rotate the first transmission rod 25, the first transmission rod 25 to rotate the bevel gear structure 24, the bevel gear structure 24 to rotate the cleaning rod 19, and the cleaning rod 19 to rotate the second spiral blade 20.

[0051] The cleaning assembly of the present invention also includes several rotating frames 28 arranged in parallel rotation inside the ventilation slot 17 and a transmission external gear ring 29 connected to the rotating frames 28.

[0057] Example 3

[0058] Based on Example 2, referring to Figure 7 and Figure 10 - Figure 11 This is the third embodiment of the invention. In this embodiment, the composting mechanism further includes a sealing assembly disposed on the rotating tube 4 and the spiral sleeve 7 to seal the ventilation hole 18. The sealing assembly includes a first sealing block 36 movably disposed in the spiral sleeve 7 and a screw drive structure 37 cooperating with the first sealing block 36. The first sealing block 36 is disposed in a region of the ventilation hole 18 that has an oblique elongated structure. The spiral sleeve 7 has a first sealing groove that fits against the first sealing block 36. The first sealing groove is disposed on the lower side of the ventilation hole 18 and communicates with the ventilation hole 18. The screw drive structure 37 is disposed on the first sealing block 36. On the outside, the lead screw drive structure 37 is provided with a second connecting block that is connected to the outer wall of the first sealing block 36. The upper side of the ventilation hole 18 is provided with a sealing block 38 that is aligned with the first sealing block 36. The spiral sleeve 7 is provided with a sealing groove that fits with the sealing block 38. The sealing block 38 is movably disposed in the sealing groove. The top end of the first sealing block 36 and the bottom end of the sealing block 38 are both set as inclined surfaces. When the first sealing block 36 is inserted into the sealing groove, the first sealing block 36 fits and controls the sealing block 38 to move in the sealing groove. The top end of the first sealing block 36 can be flush with the inner bottom surface of the ventilation hole 18.

[0059] In this embodiment, when no gas is introduced into the ventilation slot 17, the lead screw drive structure 37 is activated. The lead screw drive structure 37 drives the second connecting block to move, and the second connecting block drives the first sealing block 36 to move upward, so that the first sealing block 36 enters the ventilation hole 18 from the first sealing slot and is inserted into the sealing groove, so that the upper end face of the first sealing block 36 is in contact with the lower end face of the sealing block 38, and the sealing block 38 moves in the sealing groove, so that the first sealing block 36 fits and seals the ventilation hole 18.

[0060] The sealing assembly of the present invention also includes a first guide rod 39 disposed at the top of the sealing groove and inserted into the sealing block 38, and a reset spring 40 sleeved on the first guide rod 39. The top of the sealing block 38 is provided with a first guide hole that fits with the first guide rod 39, and a guide block 62 is provided on one side of the sealing block 38. A guide groove matching the guide block 62 is provided on the spiral sleeve 7.

[0061] In this embodiment, when the sealing block 38 moves in the sealing groove, the first guide rod 39 moves in the first guide hole, causing the reset spring 40 to be conveyed. When the sealing block 38 moves, it drives the guide block 62 to move in the guide groove.

[0062] The sealing assembly of the present invention also includes a second guide rod 41 which is vertically disposed on one side of the lead screw drive structure 37 and inserted into the first sealing block 36. The bottom end of the first sealing block 36 is provided with a second guide hole that matches the second guide rod 41, and a buffer spring 42 connected to the second guide rod 41 is provided in the guide hole.

[0063] In this embodiment, when the first blocking block 36 moves, the second guide rod 41 moves in the second guide hole, causing the buffer spring 42 to extend and retract.

[0064] The sealing assembly of this invention further includes a lifting block 43 movably disposed in the ventilation slot 17 and a lifting strip 44 disposed on one side of the lifting block 43 and guided and connected to the rotating tube 4. The rotating tube 4 has a lifting groove that matches the lifting strip 44. The sealing assembly also includes a first lifting rack 45 disposed on the other side of the lifting strip 44 and a lifting gear 46 meshing with the first lifting rack 45. One end of the lifting gear 46 is provided with a first connecting rod 47 rotatably connected to the rotating tube 4, and the other end of the first connecting rod 47 is provided with a second universal joint 48. The bottom end of the screw drive structure 37 is provided with a third universal joint 49. One end of 48 is provided with a third transmission rod 50 connected to the third universal joint 49. The third transmission rod 50 is inclined and parallel to the ventilation hole 18. The sealing assembly also includes a second connecting rod 51 vertically disposed on the outer side of the lifting block 43 and a floating ball 52 disposed at one end of the second connecting rod 51. The floating ball 52 is a hollow structure. When the lifting block 43 moves downward, the lifting gear 46 and the first lifting rack 45 cooperate to control the first sealing block 36 to move upward through the second universal joint 48, the third transmission rod 50, the third universal joint 49 and the lead screw transmission structure 37, thereby sealing the ventilation hole 18.

[0065] In this embodiment, when gas is introduced into the ventilation slot 17, the floating ball 52 moves upward, causing the second connecting rod 51 to move. The second connecting rod 51 then moves the lifting block 43 upward, causing the lifting block 43 to guide the lifting bar 44. The lifting bar 44 then moves the first lifting rack 45 upward, which in turn rotates the lifting gear 46. The lifting gear 46 then rotates the first connecting rod 47, which in turn rotates the second universal joint 48. This second universal joint 48 then rotates the third transmission rod 50. The third universal joint 49 rotates, causing it to drive the screw drive structure 37. This causes the screw drive structure 37 to move the first sealing block 36 downward, opening the ventilation hole 18 and allowing it to supply air. When the air supply to the ventilation slot 17 stops, the floating ball 52, lifting block 43, lifting bar 44, and first lifting rack 45 move downward under gravity. This causes the second universal joint 48, third drive rod 50, third universal joint 49, and screw drive structure 37 to work together to control the first sealing block 36 to move upward, sealing the ventilation hole 18.

[0066] The sealing assembly of this invention also includes a second lifting rack 53 disposed on the other side of the lifting gear 46 and meshing with the lifting gear 46, and a second sealing block 54 connected to the second lifting rack 53. A second sealing groove is provided on the rotating tube 4 to fit against the second sealing block 54. The second sealing groove is connected to the ventilation hole 18. When gas is introduced into the ventilation channel 17, the floating ball 52 causes the lifting block 43 to move upward, thereby causing the lifting gear 46 to control the second sealing block 54 to move downward. The lifting gear 46 and the lead screw transmission structure 37 control the first sealing block 36 to move downward, opening the ventilation hole 18. When gas is not introduced into the ventilation channel 17, the lifting block 43 moves downward under the action of gravity, and causes the first sealing block 36 and the second sealing block 54 to move upward, sealing the ventilation hole 18.

[0067] In this embodiment, when the lifting block 43 and the lifting bar 44 cooperate to control the lifting gear 46 to rotate, the lifting gear 46 drives the second lifting rack 53 to move. That is, when the lifting block 43 and the lifting bar 44 move downward, the second lifting rack 53 moves upward, which in turn drives the second blocking block 54 to move upward and block the ventilation hole 18.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
