Description

Technical Field

[0001] This invention relates to an ash unloading device, specifically an electric double-disc automatic ash unloading device used in conjunction with dust removal equipment. Background Technology

[0002] Existing dust removal equipment is used to filter and purify gases containing dust or ash before releasing them into the atmosphere, preventing direct emission of such gases and potential environmental pollution. In existing technologies, dust removal equipment includes a filtration chamber, a dust collection chamber, and a purification chamber. The dust collection hopper at the bottom of the filtration chamber is connected to the dust collection chamber via a pipe, and two pneumatic valves are installed on the pipe connecting the dust collection hopper to the dust collection chamber.

[0003] The specific working process is as follows: gas containing dust or waste ash enters the filter chamber for filtration and is then discharged into the atmosphere through the purification chamber. The filtered dust or waste ash first falls into the ash collection hopper. When the gas is being filtered, one pneumatic valve in the ash collection hopper near the filter chamber is in the open state, and the other pneumatic valve near the ash collection chamber is in the closed state. When collecting ash, one pneumatic valve in the ash collection hopper near the filter chamber is in the closed state, and the other pneumatic valve near the ash collection chamber is in the open state, so that the two pneumatic valves operate alternately. The advantage of this design is that it ensures the airtightness of the equipment and does not affect its negative pressure state, thereby improving the guarantee for online ash unloading.

[0004] If the sealing is affected, the negative pressure of the dust collector will make it difficult to unload dust from the ash collection hopper, or even prevent the ash collection hopper from unloading dust at all. It will also bring dust, moisture or other harmful substances from the outside air into the ash collection hopper, and the dust in the ash collection chamber will also be sucked into the ash collection hopper. This is not conducive to the collection of dust or waste ash. At the same time, this structure also has certain defects. Because two pneumatic valves are installed on the ash collection hopper at the bottom of the filter chamber and the pipeline connecting the ash collection chamber, not only does the cost of the dust collector increase, but it also requires two independent control mechanisms to control the working status of the pneumatic valves, and it is also very inconvenient to use. Summary of the Invention

[0005] The purpose of this invention is to provide an electric dual-disc automatic ash unloading device that not only has a dual-disc structure, making it highly integrated, but also has good sealing performance, and can realize the alternating action of the dual discs without the need for an additional control mechanism.

[0006] To achieve the above objectives, the technical solution of the present invention is: an electric dual-disc automatic ash unloading device, the innovation of which lies in: including an electric ash unloading valve housing, a small valve plate, a large valve plate, a small valve plate rotating mechanism, a large valve plate rotating mechanism, and an electric drive mechanism.

[0007] The electric ash discharge valve housing has open ends, and its interior includes interconnected small and large chambers. A small valve plate is rotatably disposed within the small chamber and is connected to a small valve plate rotation mechanism located on the outside of the electric ash discharge valve housing. A large valve plate is rotatably disposed within the large chamber and is connected to a large valve plate rotation mechanism located on the outside of the electric ash discharge valve housing.

[0008] The electric drive mechanism includes a drive motor, a torque limiter, and an eccentric transmission assembly. The power output shaft of the drive motor is connected to the eccentric transmission assembly via the torque limiter. The eccentric transmission assembly simultaneously engages with both the small valve plate rotation mechanism and the large valve plate rotation mechanism.

[0009] The drive motor is activated, and as the eccentric transmission assembly rotates, it drives the small valve plate rotation mechanism to rotate, causing the small valve plate to flip within the small chamber under the action of the small valve plate rotation mechanism. The small chamber is then in the open state. At this time, the large valve plate remains stationary within the large chamber, and the large chamber is in the closed state.

[0010] As the eccentric transmission assembly continues to rotate, it drives the large valve plate rotation mechanism to rotate, causing the large valve plate to flip inside the large chamber under the action of the large valve plate rotation mechanism. The large chamber is in the open state, while the small valve plate remains stationary inside the small chamber, and the small chamber is in the closed state.

[0011] In the above technical solution, the small valve plate rotation mechanism includes a small valve plate shaft, a small valve plate shaft housing, and a small linkage plate. The electric ash discharge valve housing is provided with a small shaft hole on the outer wall of the small chamber. The small valve plate shaft housing is located at the small shaft hole of the electric ash discharge valve housing. The small valve plate shaft is rotatably connected to the small valve plate shaft housing. One end of the small linkage plate passes through the small shaft hole and is detachably connected to the small valve plate shaft, and the other end is rotatably connected to the small valve plate. The eccentric transmission assembly is drively connected to the small valve plate shaft.

[0012] In the above technical solution, the bottom of the small valve plate is provided with a small connecting seat, and the other end of the small linkage plate is provided with a small connecting sleeve. The small connecting sleeve is fitted onto a small shaft that is rotatably connected to the small connecting seat. One end of the small linkage plate is provided with a shaft positioning groove, and the shaft of the small valve plate shaft is engaged in the shaft positioning groove and detachably connected to the small linkage plate by fasteners.

[0013] In the above technical solution, the large valve plate rotation mechanism includes a large valve plate shaft, a large valve plate shaft housing, and a large linkage plate. The electric ash discharge valve housing is provided with a large shaft hole on the outer wall of the large chamber. The large valve plate shaft housing is located at the large shaft hole of the electric ash discharge valve housing. The large valve plate shaft is rotatably connected to the large valve plate shaft housing. One end of the large linkage plate passes through the large shaft hole and is detachably connected to the large valve plate shaft, and the other end is rotatably connected to the large valve plate. The eccentric transmission assembly is drively connected to the large valve plate shaft.

[0014] In the above technical solution, the bottom of the large valve plate is provided with a large connecting seat, and the other end of the large linkage plate is provided with a large connecting sleeve. The large connecting sleeve is fitted onto a large shaft that is rotatably connected to the large connecting seat. One end of the large linkage plate is provided with a shaft positioning groove, and the shaft body of the large valve plate shaft is engaged in the shaft positioning groove and detachably connected to the large linkage plate through fasteners.

[0015] In the above technical solution, the eccentric transmission assembly includes an eccentric disk, an upper transmission unit, a tension spring, and a lower transmission unit. The eccentric disk is connected to a torque limiter and has a flange portion. The eccentric disk is connected to the upper and lower transmission units for transmission. The upper transmission unit is connected to a small valve plate rotation mechanism, and the lower transmission unit is connected to a large valve plate rotation mechanism. The two ends of the tension spring are connected to the upper and lower transmission units respectively, and under the limiting action of the tension spring, the outer circumferential surface of the eccentric disk is always in close contact with the upper and lower transmission units, thus limiting the running trajectory of the upper and lower transmission units.

[0016] In the above technical solution, the upper transmission unit includes an upper traveling wheel, an upper connecting plate, and an upper tension spring seat. One end of the upper tension spring seat is provided with a pin. The upper traveling wheel and the upper connecting plate are both mounted on the pin of the upper tension spring seat. The upper connecting plate is connected to the small valve plate rotation mechanism. One end of the tension spring is connected to the other end of the upper tension spring seat. The upper connecting plate is also connected to the small valve plate rotation mechanism.

[0017] The lower transmission unit includes a lower traveling wheel, a lower connecting plate, and a lower tension spring seat. One end of the lower tension spring seat has a pin. The lower traveling wheel and the lower connecting plate are both mounted on the pin of the lower tension spring seat. The lower connecting plate is connected to the large valve plate rotation mechanism. The other end of the tension spring is connected to the other end of the lower tension spring seat. The lower connecting plate is also connected to the large valve plate rotation mechanism.

[0018] Under the restraining action of the tension spring, the upper and lower traveling wheels remain in contact with the outer circumference of the eccentric disc, restricting their running trajectory. As the eccentric disc rotates, when the upper traveling wheel reaches the flange of the eccentric disc, the flange pushes the upper traveling wheel upward, driving the small valve plate rotating mechanism to rotate via the upper connecting plate. This causes the small valve plate to flip within the small chamber, opening the small chamber. At this time, the large valve plate remains stationary.

[0019] As the eccentric disc continues to rotate, when the lower traveling wheel reaches the flange of the eccentric disc, the flange of the eccentric disc presses down on the lower traveling wheel and moves it downward. This causes the large valve plate rotating mechanism to rotate via the lower connecting plate, causing the large valve plate to flip inside the large chamber. The large chamber is in an open state, while the small valve plate is in a stationary state.

[0020] In the above technical solution, the small chamber is provided with a small sleeve, and the bottom opening of the small sleeve is oblique. The small valve plate is located at the oblique opening at the bottom of the small sleeve, and when the small valve plate is stationary, it can form a sealed fit with the oblique opening at the bottom of the small sleeve. The large chamber is provided with a large sleeve, and the bottom opening of the large sleeve is oblique. The large valve plate is located at the oblique opening at the bottom of the large sleeve, and when the large valve plate is stationary, it can form a sealed fit with the oblique opening at the bottom of the large sleeve.

[0021] In the above technical solution, the electric drive mechanism also includes a protective cover disposed between the drive motor and the electric ash discharge valve housing, and the torque limiter and the eccentric transmission assembly are both disposed inside the protective cover.

[0022] In the above technical solution, the electric ash discharge valve housing includes an upper sleeve and a lower sleeve arranged vertically and having a coaxial axis. The upper sleeve forms a small chamber inside, and the lower sleeve forms a large chamber inside. The outer diameter of the upper sleeve is smaller than the outer diameter of the lower sleeve.

[0023] The positive effects of this invention are: When using the electric dual-disc automatic ash unloading device of this invention, since this invention includes an electric ash unloading valve housing, a small valve plate, a large valve plate, a small valve plate rotating mechanism, a large valve plate rotating mechanism, and an electric drive mechanism,

[0024] The electric ash discharge valve housing has open ends, and its interior includes interconnected small and large chambers. A small valve plate is rotatably disposed within the small chamber and is connected to a small valve plate rotation mechanism located on the outside of the electric ash discharge valve housing. A large valve plate is rotatably disposed within the large chamber and is connected to a large valve plate rotation mechanism located on the outside of the electric ash discharge valve housing.

[0025] The electric drive mechanism includes a drive motor, a torque limiter, and an eccentric transmission assembly. The power output shaft of the drive motor is connected to the eccentric transmission assembly via the torque limiter. The eccentric transmission assembly simultaneously engages with both the small valve plate rotation mechanism and the large valve plate rotation mechanism.

[0026] The drive motor is activated, and as the eccentric transmission assembly rotates, it drives the small valve plate rotation mechanism to rotate, causing the small valve plate to flip within the small chamber under the action of the small valve plate rotation mechanism. The small chamber is then in the open state. At this time, the large valve plate remains stationary within the large chamber, and the large chamber is in the closed state.

[0027] As the eccentric transmission assembly continues to rotate, it drives the large valve plate rotation mechanism to rotate, causing the large valve plate to flip inside the large chamber under the action of the large valve plate rotation mechanism. At this time, the large chamber is in the open state, while the small valve plate remains stationary inside the small chamber, and the small chamber is in the closed state.

[0028] When in use, this invention is installed on the ash collection hopper at the bottom of the filter chamber and the pipe connecting the ash collection chamber. During use, the different opening and closing states of the upper and lower valve plates are realized through the eccentric transmission component. That is, when one valve plate is in the flipped state, the other valve plate is in the stationary state. This invention not only has a double disc structure, making it highly integrated, but also replaces the existing technology that uses two independent pneumatic valves to control the opening and closing actions separately. It can realize the alternating action of the double discs without the need for additional control mechanisms. Moreover, it has good sealing performance, and dust or waste ash will not stick to the valve plates. At the same time, this invention is also very convenient to use and reduces the cost.

[0037] The present invention will be further described below with reference to the accompanying drawings and the given embodiments, but is not limited thereto.

[0038] like Figure 1 , 2 As shown in Figures 3, 4, 5, 6, 7, and 8, an electric double-disc automatic ash unloading device includes an electric ash unloading valve housing 1, a small valve plate 2, a large valve plate 3, a small valve plate rotation mechanism 4, a large valve plate rotation mechanism 5, and an electric drive mechanism 6.

[0039] The electric ash discharge valve housing 1 has open ends, and its interior includes a small chamber 11 and a large chamber 12 that are interconnected. The small valve plate 2 is rotatably disposed inside the small chamber 11 and is connected to a small valve plate rotating mechanism 4 located on the outside of the electric ash discharge valve housing 1. The large valve plate 3 is rotatably disposed inside the large chamber 12 and is connected to a large valve plate rotating mechanism 5 located on the outside of the electric ash discharge valve housing 1.

[0040] The electric drive mechanism 6 includes a drive motor 61, a torque limiter 62, and an eccentric transmission assembly 63. The power output shaft of the drive motor 61 is connected to the eccentric transmission assembly 63 via the torque limiter 62. The eccentric transmission assembly 63 simultaneously engages with both the small valve plate rotation mechanism 4 and the large valve plate rotation mechanism 5. A connecting seat is provided on the outer wall of the electric ash discharge valve housing 1. A motor mounting seat 60 is provided at the bottom of the drive motor 61, and the motor mounting seat 60 is detachably connected to the connecting seat of the electric ash discharge valve housing 1.

[0041] The drive motor 61 is driven to operate. As the eccentric transmission assembly 63 rotates, it drives the small valve plate rotation mechanism 4 to rotate, causing the small valve plate 2 to flip inside the small chamber 11 under the action of the small valve plate rotation mechanism 4. The small chamber 11 is in the open state. At this time, the large valve plate 3 remains stationary inside the large chamber 12, and the large chamber 12 is in the closed state.

[0042] As the eccentric transmission assembly 63 continues to rotate, the eccentric transmission assembly 63 drives the large valve plate rotation mechanism 5 to rotate, causing the large valve plate 3 to flip inside the large chamber 12 under the action of the large valve plate rotation mechanism 5. The large chamber 12 is in the open state. At this time, the small valve plate 2 remains stationary inside the small chamber 11, and the small chamber 11 is in the closed state.

[0043] like Figure 2 , 3As shown in Figures 4 and 8, in order to achieve a transmission connection between the small valve plate rotating mechanism located on the outside of the electric ash discharge valve housing 1 and the small valve plate inside the small chamber, the small valve plate rotating mechanism 4 includes a small valve plate shaft 41, a small valve plate shaft housing 42, and a small linkage plate 43. The electric ash discharge valve housing 1 has a small shaft hole on its outer wall located in the small chamber 11. The small valve plate shaft housing 42 is located at the small shaft hole of the electric ash discharge valve housing 1. The small valve plate shaft 41 is rotatably connected to the small valve plate shaft housing 42. One end of the small linkage plate 43 passes through the small shaft hole and is detachably connected to the small valve plate shaft 41, and the other end is rotatably connected to the small valve plate 2. The eccentric transmission assembly 63 is transmissionally connected to the small valve plate shaft 41. The cross-section of the small valve plate shaft housing 42 is U-shaped, and the inner surface of the small valve plate shaft housing 42 that mates with the electric ash discharge valve housing 1 is an open structure, allowing the small valve plate shaft housing 42 to communicate with the small chamber 11. This facilitates the small valve plate shaft 41 being exposed at the small shaft hole and connected to the small valve plate for transmission. The small valve plate shaft 41, housed within the small valve plate shaft housing 42, also provides excellent protection, ensuring it is not contaminated or damaged, thus preventing any impact on the normal use of the shaft.

[0044] like Figure 8 As shown, in order to achieve quick positioning and connection between the small valve plate and the small valve plate shaft 41, the bottom of the small valve plate 2 is provided with a small connecting seat 21, and the other end of the small linkage plate 43 is provided with a small connecting sleeve 431. The small connecting sleeve 431 is fitted onto the small shaft that is rotatably connected to the small connecting seat 21. One end of the small linkage plate 43 is provided with a shaft positioning groove, and the shaft body of the small valve plate shaft 41 is engaged in the shaft positioning groove and detachably connected to the small linkage plate 43 by fasteners.

[0045] like Figure 2 , 3 As shown in Figures 5 and 8, in order to achieve a transmission connection between the large valve plate rotation mechanism located on the outside of the electric ash discharge valve housing 1 and the large valve plate inside the large chamber, the large valve plate rotation mechanism 5 includes a large valve plate shaft 51, a large valve plate shaft housing 52, and a large linkage plate 53. The electric ash discharge valve housing 1 is provided with a large shaft hole on the outer wall of the large chamber 12. The large valve plate shaft housing 52 is located at the large shaft hole of the electric ash discharge valve housing 1. The large valve plate shaft 51 is rotatably connected to the large valve plate shaft housing 52. One end of the large linkage plate 53 passes through the large shaft hole and is detachably connected to the large valve plate shaft 51, and the other end is rotatably connected to the large valve plate 3. The eccentric transmission assembly 63 is transmissionally connected to the large valve plate shaft 51. The cross-section of the large valve plate shaft housing 52 is U-shaped, and the inner surface of the large valve plate shaft housing 52 that mates with the electric ash discharge valve housing 1 has an open structure, allowing the large valve plate shaft housing 52 to communicate with the large chamber 12. This facilitates the large valve plate shaft 51 being exposed at the large shaft hole and connected to the large valve plate for transmission. The large valve plate shaft 51, housed within the large valve plate shaft housing 52, also provides excellent protection, ensuring it is not contaminated or damaged, thus preventing any impact on the normal use of the shaft.

[0046] like Figure 8 As shown, in order to achieve quick positioning and connection between the large valve plate and the large valve plate shaft 51, the bottom of the large valve plate 3 is provided with a large connecting seat 31, and the other end of the large linkage plate 53 is provided with a large connecting sleeve 531. The large connecting sleeve 531 is fitted onto the large shaft that is rotatably connected to the large connecting seat 31. One end of the large linkage plate 53 is provided with a shaft positioning groove, and the shaft body of the large valve plate shaft 51 is engaged in the shaft positioning groove and detachably connected to the large linkage plate 53 by fasteners.

[0047] like Figure 1 , 6 As shown in Figures 7 and 8, in order to achieve the alternating action of the small valve plate and the large valve plate and ensure the overall sealing performance of the invention under working conditions, the eccentric transmission assembly 63 includes an eccentric disk 631, an upper transmission unit, a tension spring 632, and a lower transmission unit. The eccentric disk 631 is connected to the torque limiter 62. The eccentric disk 631 has a flange portion. The eccentric disk 631 is connected to the upper transmission unit and the lower transmission unit for transmission. The upper transmission unit is connected to the small valve plate rotation mechanism 4, and the lower transmission unit is connected to the large valve plate rotation mechanism 5. The two ends of the tension spring 632 are connected to the upper transmission unit and the lower transmission unit respectively. Under the limiting action of the tension spring 632, the outer peripheral surface of the eccentric disk 631 is always in close contact with the upper transmission unit and the lower transmission unit, restricting the running trajectory of the upper transmission unit and the lower transmission unit.

[0048] like Figure 1 , 6 As shown in Figures 7 and 8, to make the structure more reasonable, to enable the eccentric transmission assembly to drive the small valve plate and the large valve plate to move differently, and to limit the running trajectory of the upper and lower traveling wheels, ensuring that the upper and lower traveling wheels always move in contact with the outer circumferential surface of the eccentric disc, the upper transmission unit includes an upper traveling wheel 633, an upper connecting plate 634, and an upper tension spring seat 635. One end of the upper tension spring seat 635 is provided with a pin. The upper traveling wheel 633 and the upper connecting plate 634 are both mounted on the pin of the upper tension spring seat 635. The upper connecting plate 634 is connected to the small valve plate shaft 41 of the small valve plate rotation mechanism 4. One end of the tension spring 632 is connected to the other end of the upper tension spring seat 635. The upper connecting plate 634 is connected to the small valve plate rotation mechanism 4.

[0049] The lower transmission unit includes a lower traveling wheel 636, a lower connecting plate 637, and a lower tension spring seat 638. One end of the lower tension spring seat 638 is provided with a pin. The lower traveling wheel 636 and the lower connecting plate 637 are both fitted onto the pin of the lower tension spring seat 638. The lower connecting plate 637 is connected to the large valve plate shaft 51 of the large valve plate rotating mechanism 5. The other end of the tension spring 632 is connected to the other end of the lower tension spring seat 638. The lower connecting plate 637 is connected in cooperation with the large valve plate rotating mechanism 5.

[0050] like Figure 2 As shown, under the restraining action of the tension spring 632, the upper traveling wheel 633 and the lower traveling wheel 636 are always in contact with the outer circumferential surface of the eccentric disk 631, restricting the running trajectory of the upper traveling wheel 633 and the lower traveling wheel 636. As the eccentric disk 631 rotates, when the upper traveling wheel 633 reaches the flange of the eccentric disk 631, the flange of the eccentric disk 631 pushes against the upper traveling wheel 633 and moves upward. Through the upper connecting plate 634, it drives the small valve plate rotating mechanism 4 to rotate, causing the small valve plate 2 to flip in the small chamber 11. The small chamber 11 is in the open state. At this time, the large valve plate 3 is in the stationary state.

[0051] like Figure 3 As shown, as the eccentric disk 631 continues to rotate, when the lower traveling wheel 636 reaches the flange of the eccentric disk 631, the flange of the eccentric disk 631 presses down on the lower traveling wheel 636 and moves it downward. Through the lower connecting plate 637, the large valve plate rotating mechanism 5 is driven to rotate, causing the large valve plate 3 to flip inside the large chamber 12. The large chamber 12 is in the open state, and at this time the small valve plate is in the stationary state.

[0052] like Figure 2 , 3 As shown, in order to ensure the sealing of the corresponding chamber when the small valve plate or the large valve plate is stationary, and to maximize the opening for easy ash removal when the valve plate is flipped, a small sleeve 13 is provided in the small chamber 11, and the bottom opening of the small sleeve 13 is oblique. The small valve plate 2 is located at the oblique opening at the bottom of the small sleeve 13, and the small valve plate 2 can form a sealed fit with the oblique opening at the bottom of the small sleeve 13 when stationary. A large sleeve 14 is provided in the large chamber 12, and the bottom opening of the large sleeve 14 is oblique. The large valve plate 3 is located at the oblique opening at the bottom of the large sleeve 14, and the large valve plate 3 can form a sealed fit with the oblique opening at the bottom of the large sleeve 14 when stationary. A sealing ring is provided around the bottom bevel of the small sleeve 13, so that when the small valve plate 2 is attached to the bottom bevel of the small sleeve 13, the sealing ring ensures the sealing between the two. A sealing ring is also provided around the bottom bevel of the large sleeve 14, so that when the large valve plate 3 is attached to the bottom bevel of the large sleeve 14, the sealing ring ensures the sealing between the two.

[0053] like Figure 1 As shown, in order to protect the torque limiter and the eccentric transmission assembly, the electric drive mechanism 6 also includes a protective cover 64 disposed between the drive motor 61 and the electric ash discharge valve housing 1, and the torque limiter 62 and the eccentric transmission assembly 63 are both disposed inside the protective cover 64.

[0054] like Figure 2 , 3As shown, to further improve the rationality of the structure, the electric ash discharge valve housing 1 includes an upper sleeve and a lower sleeve arranged vertically and coaxially. The upper sleeve forms a small chamber 11, and the lower sleeve forms a large chamber 12. The outer diameter of the upper sleeve is smaller than that of the lower sleeve. This is also to facilitate improving the ash discharge efficiency, making the ash discharge efficiency from the sleeve greater than the dust entry efficiency into the upper sleeve. For convenient maintenance and repair, the upper sleeve is provided with an upper inspection door 15, and the lower sleeve is provided with a lower inspection door 16.

[0055] The working process of this invention is as follows: When in use, it is placed on the ash collection hopper at the bottom of the filter chamber and the pipe connecting the ash collection chamber. During use, the different opening and closing states of the upper and lower valve plates are realized through the eccentric transmission component, that is, when one valve plate is in the flipped state, the other valve plate is in the stationary state.

[0056] Specifically, the drive motor 61 is driven to operate, and the drive motor 61 drives the eccentric transmission assembly 63 through the torque limiter 62.

[0057] like Figure 2 As shown, as the eccentric disk 631 of the eccentric transmission assembly 63 rotates, the running trajectory of the upper traveling wheel 633 and the lower traveling wheel 636 is restricted by the tension spring 632, ensuring that the upper traveling wheel 633 and the lower traveling wheel 636 remain in contact with the outer circumferential surface of the eccentric disk 631. As the eccentric disk 631 rotates, when the upper traveling wheel 633 reaches the flange of the eccentric disk 631, the flange of the eccentric disk 631 pushes against the upper traveling wheel 633 and moves upward. This causes the small valve plate shaft 41 of the small valve plate rotating mechanism 4 to rotate via the upper connecting plate 634. At this time, the small valve plate shaft 41 acts as a hinge point, causing the small valve plate 2 to rotate counterclockwise downward within the small chamber 11. The small chamber 11 is in an open state, allowing dust or waste ash in the ash hopper to fall into the small chamber 11.

[0058] like Figure 3 As shown, as the eccentric disk 631 continues to rotate, the small valve plate 2 returns to its initial position, and the small chamber 11 is in a closed state. When the lower traveling wheel 636 travels to the flange of the eccentric disk 631, the flange of the eccentric disk 631 presses down on the lower traveling wheel 636 and moves it downward. Through the lower connecting plate 637, the large valve plate shaft 51 of the large valve plate rotating mechanism 5 is driven to rotate. At this time, the large valve plate shaft 51 acts as a hinge fulcrum, causing the large valve plate 3 to rotate counterclockwise downward in the large chamber 12. The large chamber 12 is in an open state, so that dust or waste ash enters the large chamber 12 and can fall directly into the dust collection chamber of the dust removal equipment.

[0059] Under the action of the eccentric transmission assembly 63, the present invention drives the small valve plate rotation mechanism 4 and the large valve plate rotation mechanism 5 to alternately operate, so that the small valve plate 2 is flipped in the small chamber 11 under the action of the small valve plate rotation mechanism 4, and the small chamber 11 is in the open state. At this time, the large valve plate 3 remains stationary in the large chamber 12, and the large chamber 12 is in the closed state; or, the large valve plate 3 is flipped in the large chamber 12 under the action of the large valve plate rotation mechanism 5, and the large chamber 12 is in the open state. At this time, the small valve plate 2 remains stationary in the small chamber 11, and the small chamber 11 is in the closed state.

[0060] This invention not only features a dual-disc structure, resulting in high integration, but also replaces the existing technology that uses two independent pneumatic valves to control the opening and closing actions. It can achieve alternating action of the dual discs without the need for additional control mechanisms, and it has good sealing performance, preventing dust or ash from sticking to the valve plate. In addition, this invention is very convenient to use and reduces manufacturing costs.

[0061] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.

The electric drive mechanism (6) includes a drive motor (61), a torque limiter (62), and an eccentric transmission assembly (63). The power output shaft of the drive motor (61) is connected to the eccentric transmission assembly (63) through the torque limiter (62). The eccentric transmission assembly (63) is simultaneously connected to the small valve plate rotation mechanism (4) and the large valve plate rotation mechanism (5). The drive motor (61) is driven to operate. As the eccentric transmission assembly (63) rotates, the eccentric transmission assembly (63) drives the small valve plate rotation mechanism (4) to rotate, causing the small valve plate (2) to flip inside the small chamber (11) under the action of the small valve plate rotation mechanism (4). The small chamber (11) is in the open state. At this time, the large valve plate (3) remains stationary inside the large chamber (12), and the large chamber (12) is in the closed state. As the eccentric transmission assembly (63) continues to rotate, it drives the large valve plate rotation mechanism (5) to rotate, causing the large valve plate (3) to flip inside the large chamber (12) under the action of the large valve plate rotation mechanism (5). The large chamber (12) is in the open state. At this time, the small valve plate (2) remains stationary in the small chamber (11), and the small chamber (11) is in the closed state. The eccentric transmission assembly (63) includes an eccentric disk (631), an upper transmission unit, a tension spring (632), and a lower transmission unit. The eccentric disk (631) is connected to a torque limiter (62). The eccentric disk (631) has a flange portion. The eccentric disk (631) is connected to the upper transmission unit and the lower transmission unit. The upper transmission unit is connected to the small valve plate rotating mechanism (4), and the lower transmission unit is connected to the large valve plate rotating mechanism (5). The two ends of the tension spring (632) are connected to the upper transmission unit and the lower transmission unit, respectively. Under the limiting action of the tension spring (632), the outer peripheral surface of the eccentric disk (631) is always in close contact with the upper transmission unit and the lower transmission unit, thus limiting the running trajectory of the upper transmission unit and the lower transmission unit. The upper transmission unit includes an upper traveling wheel (633), an upper connecting plate (634), and an upper tension spring seat (635). One end of the upper tension spring seat (635) is provided with a pin. The upper traveling wheel (633) and the upper connecting plate (634) are both mounted on the pin of the upper tension spring seat (635). The upper connecting plate (634) is connected to the small valve plate rotating mechanism (4). One end of the tension spring (632) is connected to the other end of the upper tension spring seat (635). The upper connecting plate (634) is connected to the small valve plate rotating mechanism (4). The lower transmission unit includes a lower traveling wheel (636), a lower connecting plate (637), and a lower tension spring seat (638). One end of the lower tension spring seat (638) is provided with a pin. The lower traveling wheel (636) and the lower connecting plate (637) are both mounted on the pin of the lower tension spring seat (638). The lower connecting plate (637) is connected to the large valve plate rotating mechanism (5). The other end of the tension spring (632) is connected to the other end of the lower tension spring seat (638). The lower connecting plate (637) is connected to the large valve plate rotating mechanism (5). Under the restraint of the tension spring (632), the upper traveling wheel (633) and the lower traveling wheel (636) are always in contact with the outer circumference of the eccentric disk (631), restricting the running trajectory of the upper traveling wheel (633) and the lower traveling wheel (636). As the eccentric disk (631) rotates, when the upper traveling wheel (633) reaches the flange of the eccentric disk (631), the flange of the eccentric disk (631) pushes the upper traveling wheel (633) upward, driving the small valve plate rotating mechanism (4) to rotate through the upper connecting plate (634), causing the small valve plate (2) to flip in the small chamber (11), and the small chamber (11) to be in the open state. At this time, the large valve plate (3) is in the stationary state. As the eccentric disc (631) continues to rotate, when the lower traveling wheel (636) reaches the flange of the eccentric disc (631), the flange of the eccentric disc (631) presses down on the lower traveling wheel (636) and moves it down. Through the lower connecting plate (637), the large valve plate rotating mechanism (5) is driven to rotate, so that the large valve plate (3) flips in the large chamber (12). The large chamber (12) is in the open state. At this time, the small valve plate (2) is in the stationary state.
