Description

Technical Field

[0001] The present invention relates to the technical field of waste incineration power generation, and specifically to an environment-friendly waste incineration power generation device based on multi-pollutant collaborative purification. Background Art

[0002] As is well known, waste incineration power generation is a technical means of converting municipal domestic waste and other waste into electric energy through incineration. After preliminary crushing treatment, the waste is sent into the incinerator and undergoes processes such as pyrolysis and combustion to generate high-temperature flue gas. This high-temperature flue gas passes through a waste heat boiler, transfers heat to the water in the boiler, turns the water into high-temperature and high-pressure steam, and the steam drives the steam turbine to rotate, thereby driving the generator to generate electricity, realizing the conversion from waste heat energy to electric energy.

[0003] When it comes to waste environmental protection treatment, waste incineration power generation devices can be used. The problems existing in the prior art are as follows: When conducting waste incineration treatment, multi-pollutant collaborative purification is mostly adopted. In a treatment system, multiple pollutants are efficiently removed and purified simultaneously. However, compared with incinerating single-type waste, when multiple pollutants are put into the incinerator for incineration, due to different waste types and uneven dispersion, it may lead to incomplete combustion of some waste. At the same time, there is still a lot of heat in the flue gas to be treated generated after waste incineration for power generation. Although it is not enough to continue heating the water in the boiler at a high temperature, during flue gas purification treatment, the residual temperature may cause the adsorption capacity of the adsorbent in the purification system to decline, thereby affecting the removal effect of these pollutants and possibly damaging the purification equipment.

[0004] Based on the above-mentioned situation, we found that it is very difficult for the existing environment-friendly waste incineration power generation device based on multi-pollutant collaborative purification to avoid the above problems at the same time. Therefore, we propose an environment-friendly waste incineration power generation device based on multi-pollutant collaborative purification that can reuse the flue gas after thermal power generation, reduce its temperature before entering the purification system while reusing it, homogenize the waste put in, improve its own dryness and temperature at the same time, and after preheating, reduce its moisture content so that when it enters the incinerator, it can reach the ignition point faster, burn more fully, and improve the overall combustion efficiency. Summary of the Invention

[0005] (I) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the present invention provides an environment-friendly waste incineration power generation device based on multi-pollutant collaborative purification, which has the advantages of being able to reuse the flue gas after thermal power generation, reducing its temperature before entering the purification system while reusing it, homogenizing the input waste, and simultaneously improving its own drying degree and temperature. After preheating, its moisture content is reduced, so that after entering the incinerator, it can reach the ignition point faster, burn more fully, and improve the overall combustion efficiency.

[0007] (II)Technical Solution

[0008] The above technical object of the present invention is achieved through the following technical solutions: An environment-friendly waste incineration power generation device based on multi-pollutant collaborative purification, including an incinerator and a flue gas purification system. At the top of the right feed inlet of the incinerator, there is a feed outer shell. An insulating outer shell is sleeved outside the feed outer shell. A hot flue gas pipe is installed inside the insulating outer shell. A preheating assembly is arranged inside the feed outer shell. An exhaust mechanism is installed at the rear of the feed outer shell.

[0009] The preheating assembly includes a fixed seat installed on the inner wall of the feed outer shell. A frame is arranged inside the fixed seat. A waste slide is fixedly connected inside the frame. An integrally formed shielding frame is arranged inside the waste slide.

[0010] The right side of the smoke exhaust pipe at the top of the incinerator is fixedly connected to an input pipe. The right side of the smoke exhaust pipe at the front of the flue gas purification system is fixedly connected to an output pipe. The two ends of the hot flue gas pipe are respectively communicated with the input pipe and the output pipe. A transmission shaft is rotatably connected inside the feed outer shell. A striking hammer is fixedly connected to the outside of the transmission shaft. The top of the striking hammer is used in cooperation with the waste slide.

[0011] With the above technical solution, a feed housing is provided to buffer the garbage about to be burned. During use, the material is put into the feed port of the incinerator from the feed housing. When the garbage enters the interior of the feed housing, it will fall on the top of the garbage slide plate. During normal operation, the drive shaft is driven to rotate by an externally connected drive device. While rotating, the hammer will strike the garbage slide plate. When the garbage slide plate is impacted, the frame connected to it will also vibrate along the fixed seat. At this time, various pollutants on the garbage slide plate will be evenly vibrated and dispersed to avoid incomplete combustion caused by uneven distribution of different types of pollutants during feeding. The flue gas after thermal power generation in the incinerator will be discharged from the input pipe to the hot flue pipe. The hot flue pipe is coiled in the feed housing. Therefore, it will heat the air between the feed housing and the partition housing to increase the temperature inside the feed housing, so that when the garbage is repeatedly vibrated and stays in the air briefly, it will be dried due to the temperature higher than the normal temperature, reducing the moisture inside it. At the same time, the hot air flow will directly enter the path position of the garbage through the bottom of the feed housing and the inside of the shielding frame to directly purge it, further achieving a preheating effect. After the heated garbage enters the incinerator, the garbage that is relatively difficult to burn can also reach the ignition point faster and burn more fully, indirectly improving the thermal power generation efficiency. The blown hot air flow can also be discharged from the exhaust mechanism to avoid air flow backwash.

[0012] The present invention is further configured as follows: a docking cover is welded to the left side of the feed housing, the outside of the docking cover is bolted to the feed port on the right side of the incinerator, a feeding housing is fixedly connected to the right side of the feed housing, and the inside of the flue gas purification system is connected to the exhaust pipe through an air induction device.

[0013] With the above technical solution, by providing a docking cover for connecting the feed housing and the feed port of the incinerator, it can prevent garbage leakage or rapid cooling of the preheated garbage after contacting cold air. The provided feeding housing is used to directly connect to the previous garbage crushing device or directly connect to the garbage feeding system. The air induction device provided in the flue gas purification system can generate negative pressure on the flue gas to prevent it from staying in the hot flue pipe. Since the temperature of the flue gas is further reduced by passing through the hot flue pipe, it is not easy to cause damage or accelerated aging of the air induction device due to temperature.

[0014] The present invention is further configured as follows: air flow baffles are fixedly connected to both sides of the bottom of the feed housing, a sealing plate is fixedly connected to the right side inside the partition housing, and the inside of the sealing plate is bolted to the feed housing.

[0015] With the above technical solution, by providing air flow baffles to block the air flow, it can prevent the hot air flow from outputting from both sides of the feed housing and the partition housing, resulting in unstable air flow. The provided sealing plate can improve the sealing performance between the feed housing and the partition housing, preventing the heated air from escaping and causing heat waste and thermal pollution.

[0016] The present invention is further configured such that: a connecting pin is fixedly connected to the inner side of the fixed seat, a through groove for cooperating with the connecting pin is formed in the inner side of the frame, a return spring is fixedly connected to the top of the frame, and the top of the return spring is fixedly connected to the fixed seat.

[0017] With the above technical solution, by providing the connecting pin to cooperate with the through groove, it is used to connect the fixed seat and the frame. At the same time, the frame can have a certain displacement space through the gap between the through groove and the connecting pin for its vibration, avoiding direct force on the structure which may cause deformation during long-term use. The provided return spring quickly pushes the frame and the garbage slide plate to reset after vibration, facilitating continuous operation in the later stage.

[0018] The present invention is further configured such that: air flow holes are formed in the bottom of the feeding outer shell, a frame is fixedly connected to the bottom of the partition outer shell, and a turbo fan is installed inside the frame.

[0019] With the above technical solution, by providing the frame for installing the turbo fan, the turbo fan concentrates the wind force and increases the directivity of the external air flow, can effectively cut and accelerate the air flow, making the air flow blown into the partition outer shell more concentrated and with stronger wind force, and can more effectively blow the heated air flow into the feeding outer shell through the air flow holes and blow and preheat the garbage from inside the shielding frame. The inverted U-shaped setting of the shielding frame and the continuously output air flow can also prevent the garbage from falling into the bottom of the shielding frame due to vibration.

[0020] The present invention is further configured such that: a secondary shell is fixedly connected to the rear side of the partition outer shell, an outer hoop is fixedly connected to the outside of the partition outer shell, and legs integrally formed are provided at the bottom of the outer hoop.

[0021] With the above technical solution, by providing the secondary shell, it is convenient to connect the internal rotating components. The provided outer hoop cooperates with the legs to support the structure and at the same time compensate the structure height to a position convenient for operation.

[0022] The present invention is further configured such that: the exhaust mechanism includes an exhaust outer shell, a exhaust pipe is fixedly connected to the rear side of the exhaust outer shell, the outside of the exhaust pipe penetrates through the secondary shell, and a needle punched felt filter cloth is provided inside the exhaust outer shell.

[0023] With the above technical solution, by providing the exhaust outer shell to cooperate with the exhaust pipe, after the air flow enters the feeding outer shell, it can be output through the exhaust outer shell, and the needle punched felt filter cloth blocks the garbage, and finally the air flow will be discharged from the secondary shell through the exhaust pipe.

[0024] The present invention is further configured as follows: the top and bottom of the inner side of the exhaust casing are fixedly connected with a fabric frame, the fabric frame is arranged on the rear side of the needle-punched felt filter cloth, and a clamping frame is provided on the front side of the needle-punched felt filter cloth, and the inner side of the clamping frame is penetrated by a bolt through the needle-punched felt filter cloth and is threadedly connected to the fabric frame.

[0025] By adopting the above technical solution and providing the fabric sticking frame and the clamping frame, the needle-punched felt filter cloth can be easily installed or disassembled and replaced.

[0026] The present invention is further configured as follows: the inner side of the exhaust shell is rotatably connected to a driven shaft, the outer side of the driven shaft is fixedly connected to two fixed sleeves, the outer side of the fixed sleeves is fixedly connected to two groups of rotating shaft frames, the inner side of the rotating shaft frame is rotatably connected to a striking frame, and the top of the inner side of the exhaust shell is provided with a force storage frame used in conjunction with the striking frame, both sides of the striking frame are fixedly connected to torsion springs, and the side of the torsion spring away from the striking frame is fixedly connected to the rotating shaft frame.

[0027] By adopting the above technical solution, by setting a driven shaft, the active sleeve connected to it will also rotate when it rotates, and the impact frame on the outside of the rotating shaft frame will rotate along the rotating shaft frame when it presses against the force storage frame. At this time, the torsion spring stores force, and rebounds through the torsion spring after missing the force storage frame, so that the impact frame hits the needle-punched felt filter cloth, knocking off the garbage attached to its surface, avoiding blockage of the airflow and causing failure of normal exhaust.

[0028] The present invention is further configured as follows: the outer side of the driven shaft is rotatably connected to the shaft frame, the rear side of the shaft frame is fixedly connected to the auxiliary housing, the inner side of the auxiliary housing is rotatably connected to the auxiliary shaft, the front side of the auxiliary shaft is rotatably connected to the inner side of the feed housing, the outer sides of the auxiliary shaft and the driven shaft are both fixedly connected to bevel gears, the two bevel gears are meshed together, the outer sides of the auxiliary shaft and the transmission shaft are both fixedly connected to pulleys, and the two pulleys are connected by a transmission belt.

[0029] By adopting the above technical solution, a shaft bracket is set up to install the driven shaft and enable it to rotate reasonably. The auxiliary shaft is equipped with a bevel gear to facilitate transmission between the driven shaft and the auxiliary shaft, and the pulley is equipped with a transmission belt to transmit data between the transmission shaft and the auxiliary shaft, so that the external drive device can drive the driven shaft by directly transmitting the transmission shaft.

[0030] (III) Beneficial effects

[0031] Compared with the existing technology, the present invention provides an environmentally friendly waste incineration power generation device based on multi-pollutant coordinated purification, which has the following beneficial effects:

[0032] The environmental protection type waste incineration power generation device based on multi-pollutant collaborative purification buffers the waste to be burned by setting a feeding outer shell. During use, the material is put into the feeding port of the incinerator from the feeding outer shell. When the waste enters the inside of the feeding outer shell, it will fall on the top of the waste slide plate. During normal operation, the transmission shaft is driven to rotate by an external driving device. While rotating, the hammer will strike the waste slide plate. When the waste slide plate is struck, the frame connected to it will also vibrate along the fixed seat. At this time, various pollutants falling on the waste slide plate will be evenly vibrated and dispersed to avoid incomplete combustion caused by uneven distribution of different types of pollutants during feeding. The flue gas after heat power generation in the incinerator will be discharged from the input pipe to the hot flue pipe. The hot flue pipe is coiled in the feeding outer shell. Therefore, it will heat the air between the feeding outer shell and the interlayer outer shell to increase the temperature inside the feeding outer shell, so that when the waste is repeatedly vibrated and stays in the air briefly, its drying degree will be improved because of the temperature higher than the normal temperature, and the internal moisture will be reduced. At the same time, the hot air flow will directly enter the path position of the waste through the bottom of the feeding outer shell and the inside of the shielding frame to directly blow it, further playing a preheating effect. After the heated waste enters the incinerator, the waste that is relatively difficult to burn can also reach the ignition point faster and burn more fully, indirectly improving the heat power generation efficiency. The blown hot air flow can also be discharged from the exhaust mechanism to avoid air flow backwash. Description of the Drawings

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] Embodiment 1

[0044] Please refer to Figures 1-7 , an environment-friendly waste incineration power generation device based on multi-pollutant collaborative purification, comprising an incinerator 1 and a flue gas purification system 2. A feed housing 3 is provided at the top of the feed inlet on the right side of the incinerator 1. An interlayer housing 4 is sleeved outside the feed housing 3. A hot flue gas pipe 5 is installed inside the interlayer housing 4. A preheating assembly 6 is provided inside the feed housing 3. An exhaust mechanism 7 is installed at the rear of the feed housing 3;

[0045] The right side of the smoke exhaust pipe at the top of the incinerator 1 is fixedly connected to an input pipe 11. The right side of the smoke exhaust pipe on the front side of the flue gas purification system 2 is fixedly connected to an output pipe 12. Both ends of the hot flue gas pipe 5 are communicated with the input pipe 11 and the output pipe 12 respectively;

[0046] By setting up the feeding housing 3 to buffer the waste about to be burned, during use, the material is put into the feeding port of the incinerator 1 from the feeding housing 3. When the waste enters the inside of the feeding housing 3, it will fall on the top of the waste slide plate 63. The flue gas after completing thermal power generation in the incinerator 1 is discharged into the hot flue pipe 5 from the input pipe 11. The hot flue pipe 5 is coiled in the feeding housing 3, so it will heat the air between the feeding housing 3 and the partition housing 4 to increase the temperature inside the feeding housing 3. When the waste is repeatedly vibrated and stays in the air briefly, its drying degree will be improved and its internal moisture will be reduced because of the temperature higher than the normal temperature. At the same time, the hot air flow will be directly input to the path position of the waste through the bottom of the feeding housing 3 and the inside of the shielding frame 64 to directly purge it, further achieving a preheating effect. After the heated waste enters the incinerator 1, the waste that is relatively difficult to burn can also reach the ignition point faster and burn more fully, indirectly improving the thermal power generation efficiency. The blown hot air flow can also be discharged from the exhaust mechanism 7 to avoid air flow backwash.

[0047] Among them, a docking cover 31 is welded to the left side of the feeding outer shell 3. The outer side of the docking cover 31 is bolted to the feeding port on the right side of the incinerator 1. The right side of the feeding outer shell 3 is fixedly connected to a feeding outer shell 32. The inside of the flue gas purification system 2 is connected through an air guiding device and a smoke exhaust pipe. By setting the docking cover 31, it is used to connect the feeding outer shell 3 and the feeding port of the incinerator 1 to prevent garbage leakage or the preheated garbage from rapidly cooling after contacting cold air flow. The set feeding outer shell 32 is used to be directly connected to the previous garbage crushing device or directly connected to the garbage feeding system. The air guiding device installed in the flue gas purification system 2 can generate negative pressure on the flue gas to prevent it from staying in the hot flue pipe 5. Since the temperature of the flue gas is further reduced through the hot flue pipe 5, it is not easy to cause damage or accelerated aging of the air guiding device due to temperature. Both sides of the bottom of the feeding outer shell 3 are fixedly connected with air flow baffles 13. The right side inside the partition outer shell 4 is fixedly connected with a blocking plate 14. The inside of the blocking plate 14 is bolted to the feeding outer shell 3. By setting the air flow baffles 13, it is used to block the air flow to prevent the hot air flow from outputting from both sides of the feeding outer shell 3 and the partition outer shell 4, resulting in unstable air flow. The set blocking plate 14 can improve the sealing performance between the feeding outer shell 3 and the partition outer shell 4 to prevent the heated air from escaping, causing heat waste and thermal pollution. An air flow hole 8 is opened at the bottom of the feeding outer shell 3. The bottom of the partition outer shell 4 is fixedly connected with a frame 9. A turbo fan 10 is installed inside the frame 9. By setting the frame 9, it is used to install the turbo fan 10. The turbo fan 10 concentrates the wind power and increases the directivity of the external air flow, and can effectively cut and accelerate the air flow, making the air flow blown into the partition outer shell 4 more concentrated and with stronger wind power, and can more effectively blow the heated air flow into the inside of the feeding outer shell 3 through the air flow hole 8 and blow and preheat the garbage from inside the shielding frame 64. The inverted U-shaped setting of the shielding frame 64 and the continuously output air flow can also prevent the garbage from falling into the bottom of the shielding frame 64 due to vibration. A secondary shell 19 is fixedly connected to the rear side of the partition outer shell 4. An outer hoop 20 is fixedly connected to the outside of the partition outer shell 4. The bottom of the outer hoop 20 is provided with integrally formed legs. By setting the secondary shell 19, it is convenient to connect the internal rotating components. The set outer hoop 20 and the legs are used to support the structure and at the same time compensate the structure height to a position convenient for operation. The exhaust mechanism 7 includes an exhaust outer shell 71. A smoke exhaust pipe 72 is fixedly connected to the rear side of the exhaust outer shell 71. The outside of the smoke exhaust pipe 72 penetrates through the secondary shell 19. A needle-punched felt filter cloth 73 is arranged inside the exhaust outer shell 71. By setting the exhaust outer shell 71 and the smoke exhaust pipe 72, after the air flow enters the feeding outer shell 3, it can be output through the exhaust outer shell 71, and the garbage is blocked by the needle-punched felt filter cloth 73. Finally, the air flow will be discharged from the secondary shell 19 through the smoke exhaust pipe 72. Fabric attachment frames 21 are fixedly connected to both the top and bottom inside the exhaust outer shell 71. The fabric attachment frames 21 are arranged at the rear side of the needle-punched felt filter cloth 73. A clamping frame 22 is arranged on the front side of the needle-punched felt filter cloth 73,The inner side of the card frame 22 passes through the needle-punched felt filter cloth 73 through a bolt and is threadedly connected to the fabric frame 21. By setting the fabric frame 21 and the card frame 22, the needle-punched felt filter cloth 73 can be easily installed or disassembled and replaced. The inner side of the exhaust shell 71 is rotatably connected to the driven shaft 23, and the outer side of the driven shaft 23 is fixedly connected to two fixed sleeves 24. The outer side of the fixed sleeve 24 is fixedly connected to two sets of rotating shaft frames 25. The inner side of the rotating shaft frame 25 is rotatably connected to the striking frame 26. The exhaust shell 71 is A force storage frame 27 is provided on the top for use with the striking frame 26. Torsion springs are fixedly connected to both sides of the striking frame 26. The side of the torsion spring away from the striking frame 26 is fixedly connected to the rotating shaft frame 25. By setting the driven shaft 23, the active sleeve connected thereto will also rotate when rotating, and the striking frame 26 on the outside of the rotating shaft frame 25 will rotate along the rotating shaft frame 25 when pressing the force storage frame 27. At this time, the torsion spring stores force and rebounds through the torsion spring after missing the force storage frame 27, so that the striking frame 26 hits the needle-punched felt filter cloth 7 3. Knock down the garbage attached to its surface to avoid blocking the airflow and causing abnormal exhaust. The outer side of the driven shaft 23 is rotatably connected to a shaft bracket. The rear side of the shaft bracket is fixedly connected to the auxiliary housing 19. The inner side of the auxiliary housing 19 is rotatably connected to an auxiliary shaft 28. The front side of the auxiliary shaft 28 is rotatably connected to the inner side of the feed housing 3. The auxiliary shaft 28 and the outer side of the driven shaft 23 are both fixedly connected to a bevel gear 29. The two bevel gears 29 are meshed and connected. The auxiliary shaft 28 and the outer side of the transmission shaft 17 are both fixedly connected to a pulley 30. The two pulleys 30 are connected by a transmission belt. The shaft bracket is provided to install the driven shaft 23 and enable it to rotate reasonably. The auxiliary shaft 28 cooperates with the bevel gear 29 to facilitate transmission between the driven shaft 23 and the auxiliary shaft 28, and the pulley 30 cooperates with the transmission belt to transmit transmission between the transmission shaft 17 and the auxiliary shaft 28, so that the external drive device can drive the driven shaft 23 by directly transmitting the transmission shaft 17.

[0048] Working principle of this embodiment: First, during the equipment assembly, the docking cover 31 on the left side of the feeding housing 3 is bolted to the feeding port on the right side of the incinerator 1 to ensure a tight connection, prevent garbage leakage, and prevent the garbage from contacting the cold air flow and rapidly cooling after preheating. The feeding housing 3 on the right side is connected to the previous-stage garbage crushing device or garbage feeding system. The garbage to be incinerated is put into the feeding housing 3 from the feeding housing 32. The garbage falls on the top of the garbage slide 63 inside the feeding housing 3. The flue gas after the incinerator 1 completes heat power generation is discharged from the input pipe 11 on the right side of the top smoke exhaust pipe to the hot smoke pipe 5. The hot smoke pipe 5 is coiled between the feeding housing 3 and the partition housing 4 to heat the air between the two housings, thereby increasing the internal temperature of the feeding housing 3. The turbine fan 10 concentrates and accelerates the external air flow and blows it into the partition housing 4. The heated air flow enters from the air holes 8 at the bottom of the feeding housing 3 and blows and preheats the garbage through the inside of the shielding frame 64, improving the dryness of the garbage, reducing the moisture content, enabling the garbage to reach the ignition point faster after entering the incinerator 1, and burning more fully. The hot air flow blown into the feeding housing 3 is discharged through the exhaust mechanism 7. The hot air flow first enters the exhaust housing 71, and the garbage is blocked by the needle felt filter cloth 73 inside, and then discharged from the auxiliary housing 19 through the exhaust pipe 72. The driven shaft 23 rotates inside the exhaust housing 71, driving the striking frame 26 on the outside of the fixed sleeve 24 and the rotating shaft frame 25. When the striking frame 26 presses against the energy storage frame 27, the torsion spring stores energy. After passing the energy storage frame 27, the torsion spring rebounds and strikes the needle felt filter cloth 73, knocking down the garbage attached to its surface to prevent the air flow from being blocked. The driven shaft 23 is installed on the rear side of the auxiliary housing 19 through the shaft frame. The auxiliary shaft 28 inside the auxiliary housing 19 is meshed and connected to the driven shaft 23 through the bevel gear 29 on the outside. The auxiliary shaft 28 and the transmission shaft 17 are connected by the belt pulley 30 and the transmission belt on the outside, enabling the external drive device to drive the driven shaft 23 by driving the transmission shaft 17.

[0050] Reference Figures 1-8 , an environment-friendly garbage incineration power generation device based on multi-pollutant collaborative purification further includes a preheating component 6. Among them, the preheating component 6 includes a fixed seat 61 installed on the inner wall of the feeding housing 3. A frame 62 is provided inside the fixed seat 61. A garbage slide 63 is fixedly connected to the inside of the frame 62. A shielding frame 64 is integrally formed inside the garbage slide 63;

[0051] A transmission shaft 17 is rotatably connected to the inside of the feeding housing 3. A striking hammer 18 is fixedly connected to the outside of the transmission shaft 17. The top of the striking hammer 18 is used in cooperation with the garbage slide 63;

[0052] During normal operation, the transmission shaft 17 is driven to rotate by an external driving device. While rotating, the hammer 18 strikes the garbage slide plate 63. When the garbage slide plate 63 receives the impact, the frame 62 connected thereto will also vibrate along the fixed seat 61. At this time, various pollutants falling on the garbage slide plate 63 will be evenly vibrated and dispersed to avoid incomplete combustion caused by uneven distribution of different types of pollutants during feeding.

[0053] Among them, a connecting pin 15 is fixedly connected to the inner side of the fixed seat 61, a through groove for cooperating with the connecting pin 15 is provided on the inner side of the frame 62, a return spring 16 is fixedly connected to the top of the frame 62, and the top of the return spring 16 is fixedly connected to the fixed seat 61. By setting the connecting pin 15 to cooperate with the through groove, it is used to connect the fixed seat 61 and the frame 62. At the same time, the frame 62 can have a certain displacement space through the gap between the through groove and the connecting pin 15 for vibration, so as to avoid direct force on the structure and cause deformation during long-term use. The provided return spring 16 quickly pushes the frame 62 to reset after the frame 62 and the garbage slide plate 63 vibrate, facilitating subsequent continuous operation.

[0054] The working principle of this embodiment: During normal operation, an external driving device drives the transmission shaft 17 to rotate, driving the hammer 18 to strike the garbage slide plate 63, causing the frame 62 to vibrate along the fixed seat 61, evenly dispersing various pollutants on the garbage slide plate 63, avoiding incomplete combustion caused by uneven feeding. After vibration, the return spring 16 quickly pushes the frame 62 to reset, ensuring subsequent continuous operation. The cooperation with the hot air flow output from the shielding frame 64 can increase its preheating efficiency in cooperation with the vibration effect.
