Description

Technical Field

[0001] This invention relates to the field of combustion technology, and in particular to a staged combustion device for a plasma combustion system. Background Technology

[0002] The plasma combustion system's staged combustion device is a combustion optimization device and an important component of energy-saving generators. In coal-fired power generation systems, the plasma combustion system's staged combustion device works by having air carrying pulverized coal enter the combustion unit, where it is ignited to generate a high-temperature, high-pressure hot gas flow. To improve energy efficiency, the air containing pulverized coal undergoes thermal exchange with the generator's exhaust gas before ignition, resulting in hot gas and raising the pre-combustion gas temperature. However, under high temperature, impurities in the pulverized coal combine with oxygen to form non-combustible solid particles, such as iron oxide particles formed from iron ore impurities. These components enter the hot gas flow with the combustion process. As the system continues to operate, these solid particles, carried by the high-temperature, high-pressure hot gas flow, impact the generator's turbine blades at high speed, damaging the blade's streamlined surface and reducing the airflow's work efficiency. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a staged combustion device for a plasma combustion system.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a plasma combustion system staged combustion device, comprising a plasma burner connecting pipe, a plasma combustion guide pipe provided on the plasma burner connecting pipe, a pulverized coal inlet pipe fixedly connected to the plasma combustion guide pipe, and the pulverized coal inlet pipe being fixedly connected to the plasma burner connecting pipe, two fixed arms fixedly connected inside the pulverized coal inlet pipe, and a processing component for treating impurities in the hot gas flow provided on the fixed arms, the processing component containing a filter disc and a movable bolt, the cooperation of the filter disc and the movable bolt providing power for treating impurities, and two fixed columns within the processing component, the filter disc being fixedly connected inside the pulverized coal inlet pipe. The filter disc has several circular holes for filtration. Each fixed arm is L-shaped, and each fixed post is fixedly connected to the corresponding fixed arm. Each fixed post is fixedly connected to the inner wall of the pulverized coal inlet pipe. A bearing block is fixedly connected to the bottom of each of the two fixed arms, and a movable bolt is movably connected to the bearing block. A flow divider is fixedly connected between the two fixed arms, and a placement post is fixedly connected inside the flow divider. Two second sleeves are movably connected to the outer side of the placement post, and a first sleeve is provided between the two second sleeves. The first sleeve is movably connected to the placement post. Two baffles are provided on the outer side of the placement post, and the two baffles are fixedly connected to the two second sleeves and one first sleeve, respectively.

[0005] With the above technical solution, when it is necessary to adjust the airflow of the plasma combustion system, the movable bolt is rotated, and the movable bolt moves towards the position of the baffle plate when it rotates. Then, the movable bolt drives the baffle bar to rotate when it rotates. When the baffle bar rotates, it pushes the two baffle plates to expand. When the baffle plates expand, they block the hot airflow entering the plasma combustion guide tube. When the hot gas passes through, the filter plate intercepts the iron oxide solid particles.

[0006] In a preferred embodiment of the present invention, a flow divider is provided on the fixed arm, and an adjustment component for cooperating with the processing assembly is provided on the flow divider. The adjustment component contains a tension spring and a scraper frame. The hot airflow speed can be adjusted by the cooperation of the tension spring and the scraper frame. The adjustment component contains two positioning bolts. Each baffle has a placement hole for placing the positioning bolt, and each positioning bolt is fixedly connected to the corresponding placement hole of the baffle. A positioning block is movably connected to the outside of each positioning bolt. A tension spring is positioned between the two positioning blocks, and both ends of the tension spring are fixedly connected to the two positioning blocks respectively. A baffle is fixedly connected to the top of the movable bolt, and a bearing plate is fixedly connected to the bottom of each of the two baffles. The bearing plate is sleeved on the two... Outside the spoiler, the adjustment assembly has a processing platform, which is fixedly connected to the outside of the movable bolt. The processing platform consists of a disc and several long strips, and each long strip of the processing platform is fixedly connected to several positioning cylinders. Each positioning cylinder has an extension post inserted into it. Each positioning cylinder has a spring inside it, and each spring is sleeved on the outside of the corresponding extension post. Each extension post has a scraper fixedly connected to its bottom. Several contact strips are fixedly connected to the top of the filter disc, and the scraper is in contact with the filter disc. The spoiler strip consists of a ring and two long circular blocks. When the long circular block part of the spoiler strip rotates to the position corresponding to the two spoilers, the long circular block part of the spoiler strip is in contact with the spoiler.

[0007] Through the above technical solution, when the equipment needs to be shut down and the iron oxide solid particles inside the equipment need to be cleaned, as the two baffles expand, the two baffles drive the corresponding positioning bolts to move. The positioning bolts, in turn, drive the positioning blocks to move, and the positioning blocks, in turn, stretch the positioning bolts. Then, as the baffles expand, they squeeze the scraper frame upwards towards the position of the diverter strip. As the scraper frame rises, it scrapes away the impurities attached to the outside of the baffles. When the diverter strip leaves the position corresponding to the baffles, the stretched tension spring rebounds, causing the two baffles to reset. The reset of the two baffles then causes the scraper frame to reset, thereby repositioning the support plate. The scraper frame is limited and blocked. When the movable bolt rotates, it drives the processing table to rotate. When the processing table rotates, it drives the corresponding positioning cylinder to rotate. When the positioning cylinder rotates, it drives the extension column to rotate. When the extension column rotates, it drives the scraper to rotate. When the scraper rotates, it processes the impurities attached to the top of the filter disc. When solid particles are stuck in the round hole of the filter disc, the scraper rotates to the position of the opening contact bar. The opening contact bar pushes the scraper to rise. When the scraper leaves the position corresponding to the opening contact bar, the spring rebounds and drives the scraper to fall down, generating vibration. The vibration generated by the scraper falling down causes the solid particles stuck in the round hole of the filter disc to fall down.

[0008] In a preferred embodiment of the present invention, a pressure block is fixedly connected inside the pulverized coal inlet pipe. The pressure block is equipped with a contacting component for cooperating with an adjusting assembly. The contacting component contains a support column and a collection box. The cooperation of the support column and the collection box allows for the collection of processed impurities. A support platform is provided inside the contacting component, and the support platform is fixedly connected to the pressure block. The end of the pressure block away from the support platform is fixedly connected to the pulverized coal inlet pipe. A bearing is fixedly connected to the top of the bearing platform. A support column is fixedly connected to the inner ring of the bearing on the bearing platform. An extension strip is fixedly connected to the outer side of the bearing platform, and a blocking column is fixedly connected to the extension strip. The support column has a U-shaped annular groove for placing the blocking column, which is inserted into the U-shaped annular groove. Several collection boxes are fixedly connected to the outer side of the support column. An insert is fixedly connected to the top of the support column, and the bottom of the movable bolt is provided with a mechanism for releasing... The insert has a slot. When the insert moves to the position corresponding to the movable bolt, the insert engages in the slot of the movable bolt. The contact assembly also has a machine base, which is fixedly connected to the outside of the support platform. The top of the machine base is fixedly connected to the housing. The housing contains a servo motor. A transmission column is movably connected to the machine base. The output shaft of the servo motor is fixedly connected to the transmission column. A scraper frame is fixedly connected to the support platform. A trigger cylinder is movably connected to the scraper frame. A toothed ring is fixedly connected to the bottom of the trigger cylinder. A limit post is fixedly connected to the bottom of the toothed ring. A limit strip is connected to the outside of the limit post. A rack is inserted into the limit strip. A trigger post is fixedly connected to the outside of the rack. A starting strip is movably connected to the outside of the trigger post. The starting strip is fixedly connected to the transmission column. A track post is fixedly connected to the outside of the support post. The trigger cylinder has an inverted V-shaped groove for placing the track post, and the track post is inserted into the inverted V-shaped groove of the trigger cylinder.

[0009] With the above technical solution, when the movable bolt needs to rotate, the servo motor is started. When the servo motor rotates, it drives the transmission column to rotate. When the transmission column rotates, it drives the starting bar to rotate. When the starting bar rotates, it pushes the trigger column to move. When the trigger column moves, it pushes the rack to move. When the rack moves, it pushes the gear ring to rotate. When the gear ring rotates, it pushes the track column to move. Then, when the track column moves, it moves towards the top of the inverted V-groove of the trigger cylinder. In turn, the track column drives the support column to rise. Then, the support column drives the insert bar to enter the slot of the movable bolt. When the track column moves to the top of the inverted V-groove of the trigger cylinder, the blocking column enters the bottom of the U-shaped ring groove of the support column. Then, when the gear ring rotates, it drives the support column to rotate. When the support column rotates, it drives the movable bolt to rotate. In turn, when the support column rotates, it drives the collecting device to rotate and collect the impurities that fall from the filter disc.

[0010] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention, through the arrangement of processing components, adjustment components, and contact components, enables the following during the normal combustion and gas production process of the staged combustion device in the plasma combustion system: when the hot gas flow containing iron oxide solid particles flows through the pulverized coal inlet pipe, the movable bolt and the processing table drive the scraper to continuously rotate along the surface of the filter disc, which can accurately intercept the iron oxide solid particles remaining in the hot gas flow and prevent them from impacting the turbine blades with the high-speed hot gas flow; when cleaning is performed during equipment shutdown or low-load operation, the scraper generates periodic vibration under the lifting action of the contact bar and the spring reset action, effectively loosening and discharging the particles stuck in the filter disc mesh, avoiding blockage, and realizing the dual functions of protection during operation and clearing blockage after shutdown.

[0011] 2. This invention, through the arrangement of processing components, adjustment components, and contact components, and the circular hole structure of the pulverized coal inlet pipe and the filter disc, utilizes the structural layout of the pulverized coal inlet pipe and the filter disc with circular holes. Combined with the elastic support of the extension column by the spring inside the positioning cylinder, the scraper blade remains in contact with the filter disc during rotation, thereby achieving dynamic scraping and cleaning of iron oxide particles adsorbed on the surface and preventing the accumulation of impurities from affecting the filtration efficiency.

[0012] 3. By setting up processing components, adjustment components, and contact components, and through the contact transmission between the disturbance strip and the turbulence plate, combined with the elastic reset function of the tension spring, the expansion angle of the turbulence plate can be flexibly adjusted, thereby controlling the hot airflow through the cross section, achieving precise control of airflow speed, adapting to the combustion requirements of plasma combustion guide tubes under different loads, and improving fuel combustion uniformity.

[0013] 4. By setting up processing and adjustment components, this invention enables the scraper to automatically scrape off attached impurities during the expansion and repositioning process of the baffle plate when impurities accumulate on its surface due to long-term contact with dusty airflow or during regular system maintenance, through the squeezing linkage with the scraper frame. The scraper frame moves up and down along the surface of the baffle plate, and the bearing plate limits the scraper frame, ensuring a stable and reliable cleaning process, keeping the surface of the baffle plate clean, avoiding flow field turbulence caused by impurity accumulation, and ensuring the efficiency of airflow.

[0014] 5. The movable bolt of this invention, in conjunction with the processing table, positioning cylinder, and extension column, drives the scraper to rotate along the surface of the filter disc. The elastic support of the extension column by the spring ensures that the scraper and the filter disc are in close contact, thereby improving the cleaning effect of impurities.

[0015] 6. By adjusting the components and contacting components, and by designing a fixed connection between the support column and the collection box, the present invention allows the collection box to simultaneously receive impurities falling from the filter disc and the baffle plate during the rotation of the support column, thereby achieving centralized collection of impurities. This eliminates the need for frequent manual disassembly and cleaning, reducing the workload and maintenance costs of the equipment. Attached Figure Description

Detailed Implementation

[0018] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0019] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the plasma combustion system staged combustion device includes a plasma burner connecting pipe 1, a plasma combustion guide pipe 2 on the plasma burner connecting pipe 1, a pulverized coal inlet pipe 3 fixedly connected to the plasma combustion guide pipe 2, and the pulverized coal inlet pipe 3 fixedly connected to the plasma burner connecting pipe 1. Two fixed arms 4 are fixedly connected inside the pulverized coal inlet pipe 3. The fixed arms 4 are equipped with a processing component for treating impurities in the hot gas flow. The processing component contains a filter disc 11 and a movable bolt 13. The cooperation of the filter disc 11 and the movable bolt 13 provides power for treating impurities. Two fixed columns 5 are provided inside the processing component. The filter disc 11 is fixedly connected inside the pulverized coal inlet pipe 3. The filter disc 11 is equipped with several... For the filter's circular holes, each fixed arm 4 is L-shaped, and each fixed post 5 is fixedly connected to the corresponding fixed arm 4. Each fixed post 5 is fixedly connected to the inner wall of the coal powder inlet pipe 3. The bottom of each of the two fixed arms 4 is fixedly connected to a bearing block 12, and a movable bolt 13 is movably connected in the bearing block 12. A diversion strip 6 is fixedly connected in the middle of the two fixed arms 4. A placement post 7 is fixedly connected inside the diversion strip 6. Two second sleeves 9 are movably connected to the outer side of the placement post 7. A first sleeve 8 is provided between the two second sleeves 9, and the first sleeve 8 is movably connected to the placement post 7. Two baffles 10 are provided on the outer side of the placement post 7, and the two baffles 10 are fixedly connected to the two second sleeves 9 and one first sleeve 8, respectively. like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when the airflow of the plasma combustion system needs to be adjusted, the movable bolt 13 is rotated, and the movable bolt 13 moves towards the position of the baffle 10 during rotation. The movable bolt 13 then drives the baffle bar 14 to rotate, and the baffle bar 14 pushes the two baffles 10 to expand during rotation. As the baffles 10 expand, they block the hot airflow entering from the plasma combustion guide pipe 2. When the hot gas passes through, the filter disk 11 intercepts the iron oxide solid particles. Specifically, the outer diameter of the iron oxide solid particles is relatively large, and the mesh size of the filter disk is smaller than the outer diameter of the iron oxide solid particles, much larger than the outer diameter of the coal powder, thus achieving the purpose of filtration. The specific size of the mesh size of the filter disk can be adjusted by those skilled in the art according to different qualities of coal. The specific process can be obtained through a limited number of experiments and is existing technology, so it will not be described in detail here.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the fixed arm 4 is equipped with a flow divider 6, and the flow divider 6 is equipped with an adjustment component for cooperating with the processing assembly. The adjustment component contains a tension spring 17 and a scraper frame 43. The hot airflow speed can be adjusted by the cooperation of the tension spring 17 and the scraper frame 43. The adjustment component contains two positioning bolts 15. Each baffle 10 has a placement hole for placing the positioning bolt 15. Each positioning bolt 15 is fixedly connected to the corresponding placement hole of the baffle 10. A positioning block 16 is movably connected to the outside of each positioning bolt 15. The tension spring 17 is located between the two positioning blocks 16, and both ends of the tension spring 17 are fixedly connected to the two positioning blocks 16 respectively. A baffle strip 14 is fixedly connected to the top of the movable bolt 13. A support plate 44 is fixedly connected to the bottom of each of the two baffles 10. The support plate 44 is sleeved on the outside of the two baffles 10. The adjustment assembly includes a processing platform 18, which is fixedly connected to the outside of the movable bolt 13. The processing platform 18 consists of a disc and several long strips. Each long strip of the processing platform 18 is fixedly connected to several positioning cylinders 19. Each positioning cylinder 19 is inserted with an extension post 20. Each positioning cylinder 19 has a spring 21 inside, and each spring 21 is sleeved on the outside of the corresponding extension post 20. Each extension post 20 has a scraper 22 fixedly connected to its bottom. The top of the filter disc 11 is fixedly connected to several contact strips 45, and the scraper 22 is in contact with the filter disc 11. The disturbance strip 14 consists of a ring and two round blocks. When the round block part of the disturbance strip 14 rotates to the position corresponding to the two baffles 10, the round block part of the disturbance strip 14 is in contact with the baffles 10. like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, when the equipment is shut down and the iron oxide solid particles inside the equipment need to be cleaned, when the two baffles 10 expand, the two baffles 10 drive the corresponding positioning bolts 15 to move. When the positioning bolts 15 move, they drive the positioning blocks 16 to move. When the positioning blocks 16 move, they drive the positioning bolts 15 to stretch. Then, when the baffles 10 expand, they squeeze the scraper frame 43 and rise towards the position of the diverter strip 6. When the scraper frame 43 rises, it scrapes off the impurities attached to the outside of the baffles 10. When the baffle strip 14 leaves the position corresponding to the baffles 10, the stretched tension spring 17 rebounds and drives the two baffles 10 to reset. When the two baffles 10 reset, they drive the scraper frame 43 to reset. Then, the bearing plate 44 performs a pressure adjustment on the scraper frame 43. The limit stop is activated when the movable bolt 13 rotates, which drives the processing table 18 to rotate. When the processing table 18 rotates, it drives the corresponding positioning cylinder 19 to rotate. When the positioning cylinder 19 rotates, it drives the extension column 20 to rotate. When the extension column 20 rotates, it drives the scraper 22 to rotate. When the scraper 22 rotates, it processes the impurities attached to the top of the filter disc 11. When solid particles are stuck in the round hole of the filter disc 11, the scraper 22 rotates to the position of the opening contact bar 45. The opening contact bar 45 pushes the scraper 22 to rise. When the scraper 22 leaves the position corresponding to the opening contact bar 45, the spring 21 rebounds and drives the scraper 22 to fall and generate vibration. The vibration generated by the falling scraper 22 causes the solid particles stuck in the round hole of the filter disc 11 to fall.

[0021] like Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, a pressure block 23 is fixedly connected inside the pulverized coal inlet pipe 3. The pressure block 23 is equipped with a contacting component for cooperating with the adjusting assembly. The contacting component contains a support column 28 and a collection box 30. The cooperation of the support column 28 and the collection box 30 allows for the collection of processed impurities. A support platform 24 is provided inside the contacting component, and the support platform 24 is fixedly connected to the pressure block 23. The end of the pressure block 23 furthest from the support platform 24 is fixedly connected to the pulverized coal inlet pipe 3. A pressure platform 25 is fixedly connected to the top of the support platform 24, and a... The pressure plate 25 has a bearing. A support column 28 is fixedly connected to the inner ring of the bearing. An extension bar 26 is fixedly connected to the outer side of the pressure plate 25. A blocking column 27 is fixedly connected to the extension bar 26. The support column 28 has a U-shaped annular groove for placing the blocking column 27, which is inserted into the U-shaped annular groove. Several collection boxes 30 are fixedly connected to the outer side of the support column 28. An insert bar 29 is fixedly connected to the top of the support column 28. The bottom of the movable bolt 13 has a slot for placing the insert bar 29. When the insert bar 29 moves... When the movable pin 13 is in position, the insert 29 engages in the slot of the movable pin 13. The contact assembly also includes a machine base 33, which is fixedly connected to the outside of the support platform 24. A housing 31 is fixedly connected to the top of the machine base 33. A servo motor 32 is housed inside the housing 31. A transmission column 34 is movably connected to the machine base 33. The output shaft of the servo motor 32 is fixedly connected to the transmission column 34. A scraper frame 43 is fixedly connected to the support platform 24. A trigger cylinder 36 is movably connected to the scraper frame 43. The bottom of the trigger cylinder 36... A toothed ring 40 is fixedly connected. A limit post 38 is fixedly connected to the bottom of the toothed ring 40. A limit strip 39 is connected to the outside of the limit post 38. A rack 41 is inserted into the limit strip 39. A trigger post 42 is fixedly connected to the outside of the rack 41. A starting strip 35 is movably connected to the outside of the trigger post 42. The starting strip 35 is fixedly connected to the transmission post 34. A track post 37 is fixedly connected to the outside of the support post 28. An inverted V-shaped groove is provided on the trigger cylinder 36 for placing the track post 37. The track post 37 is inserted into the inverted V-shaped groove of the trigger cylinder 36. like Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, when the movable bolt 13 needs to rotate, the servo motor 32 is started. The servo motor 32 rotates, driving the transmission column 34 to rotate. The transmission column 34 rotates, driving the starting bar 35 to rotate. The starting bar 35 rotates, pushing the trigger column 42 to move. The trigger column 42 moves, pushing the rack 41 to move. The rack 41 moves, pushing the gear ring 40 to rotate. The gear ring 40 rotates, pushing the track column 37 to move. Then, the track column 37 moves, pushing it towards the top of the inverted V-groove of the trigger cylinder 36. The movement causes the track column 37 to lift the support column 28, which in turn causes the insert 29 to enter the slot of the movable bolt 13. When the track column 37 moves to the top of the inverted V-shaped groove of the trigger cylinder 36, the blocking column 27 enters the bottom of the U-shaped annular groove of the support column 28. Then, the toothed ring 40 rotates, causing the support column 28 to rotate. As the support column 28 rotates, it causes the movable bolt 13 to rotate. As the support column 28 rotates, it causes the collecting container 30 to rotate, collecting the impurities that fall from the filter disc 11.

[0022] Working principle: First step, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when it is necessary to adjust the airflow of the plasma combustion system, the movable plug 13 is rotated, and the movable plug 13 moves toward the position of the baffle 10 when it rotates. Then, the movable plug 13 drives the baffle bar 14 to rotate when it rotates. The baffle bar 14 pushes the two baffles 10 to expand when it rotates. When the baffles 10 expand, they block the hot airflow entering the plasma combustion guide tube 2. When the hot gas passes through, the filter plate 11 intercepts the iron oxide solid particles. The second step, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, when the equipment is shut down and the iron oxide solid particles inside the equipment need to be cleaned, when the two baffles 10 expand, the two baffles 10 drive the corresponding positioning bolts 15 to move. When the positioning bolts 15 move, they drive the positioning blocks 16 to move. When the positioning blocks 16 move, they drive the positioning bolts 15 to stretch. Then, when the baffles 10 expand, they squeeze the scraper frame 43 and rise towards the position of the diverter strip 6. When the scraper frame 43 rises, it scrapes off the impurities attached to the outside of the baffles 10. When the baffle strip 14 leaves the position corresponding to the baffles 10, the stretched tension spring 17 rebounds and drives the two baffles 10 to reset. When the two baffles 10 reset, they drive the scraper frame 43 to reset. Then, the bearing plate 44 performs a pressure adjustment on the scraper frame 43. The limit stop is activated when the movable bolt 13 rotates, which drives the processing table 18 to rotate. When the processing table 18 rotates, it drives the corresponding positioning cylinder 19 to rotate. When the positioning cylinder 19 rotates, it drives the extension column 20 to rotate. When the extension column 20 rotates, it drives the scraper 22 to rotate. When the scraper 22 rotates, it processes the impurities attached to the top of the filter disc 11. When solid particles are stuck in the round hole of the filter disc 11, the scraper 22 rotates to the position of the opening contact bar 45. The opening contact bar 45 pushes the scraper 22 to rise. When the scraper 22 is away from the position corresponding to the opening contact bar 45, the spring 21 rebounds and drives the scraper 22 to fall and generate vibration. The vibration generated by the falling scraper 22 causes the solid particles stuck in the round hole of the filter disc 11 to fall. The third step, as Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, when the movable bolt 13 needs to rotate, the servo motor 32 is started. The servo motor 32 rotates, driving the transmission column 34 to rotate. The transmission column 34 rotates, driving the starting bar 35 to rotate. The starting bar 35 rotates, pushing the trigger column 42 to move. The trigger column 42 moves, pushing the rack 41 to move. The rack 41 moves, pushing the gear ring 40 to rotate. The gear ring 40 rotates, pushing the track column 37 to move. Then, the track column 37 moves, pushing it towards the top of the inverted V-groove of the trigger cylinder 36. The movement causes the track column 37 to lift the support column 28, which in turn causes the insert 29 to enter the slot of the movable bolt 13. When the track column 37 moves to the top of the inverted V-shaped groove of the trigger cylinder 36, the blocking column 27 enters the bottom of the U-shaped annular groove of the support column 28. Then, the toothed ring 40 rotates, causing the support column 28 to rotate. As the support column 28 rotates, it causes the movable bolt 13 to rotate. As the support column 28 rotates, it causes the collecting container 30 to rotate, collecting the impurities that fall from the filter disc 11.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
