Description

Technical Field

[0001] This invention relates to the field of waste incineration technology, specifically to a feed processing structure for a waste incinerator. Background Technology

[0002] In the field of harmless treatment of industrial and domestic waste, incineration is the core technical means to achieve waste reduction and harmlessness. The feed treatment structure is the core component of the incinerator, which directly determines the sufficiency of waste incineration, the continuity of equipment operation, and the compliance of environmental emission standards. Among the currently disclosed prior art, Chinese invention patent with announcement number CN117553301B discloses a rotary waste gas incineration integrated treatment device. This device realizes the incineration treatment of waste through a rotary incineration structure and is equipped with a waste gas treatment mechanism to purify the incineration flue gas, which to a certain extent meets the basic needs of waste incineration and waste gas treatment. However, this existing technology still has obvious technical defects: the feeding structure of this scheme can only realize basic waste feeding, and cannot pre-crush the waste during the feeding stage. Large pieces and high-humidity waste are prone to incomplete combustion and coking after entering the incineration chamber directly, which greatly reduces the combustion efficiency and easily produces toxic and harmful flue gas. This scheme lacks a drying pretreatment structure in the feeding stage. After high-humidity waste is fed in, it will greatly reduce the temperature of the incineration chamber, increase fuel consumption, and exacerbate the problem of incomplete combustion. This scheme cannot achieve continuous isolation between feeding and incineration, which can easily lead to the safety hazard of backflow of combustion flue gas from the feed inlet. At the same time, it cannot achieve quantitative and uniform feeding of waste, resulting in large fluctuations in the load of the incinerator and insufficient operational stability, which cannot meet the needs of large-scale and continuous waste incineration treatment.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a planetary gear structure to drive the central cylinder and the rotating seat to rotate in opposite directions. Combined with the counter-rotation of the auxiliary fan blades and the main fan blades, it can efficiently shear and crush waste during the feeding stage, breaking large waste items into small particles, greatly improving the sufficiency of subsequent incineration and avoiding coking and agglomeration problems. At the same time, the tilt angle of the main fan blades can be switched by rotating the structure to realize the function switching between crushing and air drying. No additional multiple drive mechanisms are required. The equipment has a compact structure and high functional integration.

[0013] 2. This invention, by switching the angles of the main fan blades and the auxiliary fan blades, and in conjunction with the circulating air path formed by the flow box, the air outlet and the air inlet, can utilize the residual heat of the incineration chamber to dry the high-humidity waste during the feeding stage with hot air, reduce the moisture content of the waste, avoid the temperature drop of the incineration chamber caused by the feeding of high-moisture materials, and reduce the consumption of auxiliary fuel. At the same time, the bumping and lifting structure drives the storage plate to bump, so that the hot air can fully penetrate the material layer, improving the drying uniformity and efficiency.

[0014] 3. This invention, through the cooperation of the suction duct, auxiliary fan blades, and main fan blades, can form a continuous downward negative pressure during the feeding process, preventing the flue gas in the incineration chamber from flowing back into the feeding channel and eliminating safety hazards. At the same time, through the cooperation of the threaded rod, coupling, and storage plate, the quantitative lifting and feeding of waste can be realized, ensuring uniform feeding of the incinerator, stable load, and improving the continuity and stability of equipment operation.

[0015] 4. This invention, through a bumping and lifting structure combined with a one-way trough and a one-way plate, enables the crushed and dried material to automatically fall into the incineration chamber without manual intervention, achieving continuous operation. At the same time, the storage plate can rotate synchronously, and with the scraping of the auxiliary fan blades, the material is evenly fed, avoiding material accumulation and further improving the uniformity and completeness of incineration.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-9 The present invention provides a technical solution: a feeding structure for a waste incinerator, including an incineration box 1, a gas pipe 43 installed at the bottom of the incineration box 1, a heat insulation cylinder 38 installed at the upper slot of the gas pipe 43, a storage plate 9 placed at the upper end of the heat insulation cylinder 38, and a bumping and lifting structure provided at the lower end of the storage plate 9. The center of the storage plate 9 is movably connected to the central cylinder 3. Several auxiliary fan blades 4 are fixedly connected to the outer wall of the upper end of the central cylinder 3. The upper end of the central cylinder 3 is fixedly connected to the sleeve 6. The outer wall of the sleeve 6 is fitted with a rotating blade mechanism 5. The rotating blade mechanism 5 includes a rotating seat 11, and a number of connecting shafts 12 are rotatably connected to the outer side wall of the rotating seat 11. Each connecting shaft 12 is fixedly connected to a main fan blade 16 at the end away from the rotating seat 11. A rotating structure is provided between the connecting shaft 12 and the central cylinder 3, which can drive the connecting shaft 12 to rotate. The upper end of the rotating seat 11 is provided with a planetary gear structure, which can drive the central cylinder 3 and the rotating seat 11 to rotate synchronously, and the central cylinder 3 and the rotating seat 11 rotate in opposite directions. A suction tube 7 is fitted on the outer wall of the upper end of the sleeve 6. A drive shaft 8 is also fixedly connected to the upper end of the sleeve 6, and the drive shaft 8 extends to the upper surface of the incinerator 1. A drive structure is installed at the upper end of the incinerator 1.

[0020] Specifically, the inner cavities of the suction tube 7, sleeve 6, central tube 3, and air pipe 43 are interconnected. Furthermore, when the rotating structure does not drive the main fan blade 16 to rotate, the tilt states of the auxiliary fan blade 4 and the upper main fan blade 16 are symmetrical. (Refer to...) Figure 2 , Figure 4When the auxiliary fan blade 4 is tilted at 45 degrees, the main fan blade 16 is tilted at 135 degrees. Then, when the sleeve 6 is driven to rotate, it will drive the rotating blade mechanism 5 to rotate in the opposite direction through the planetary gear structure. Thus, although the auxiliary fan blade 4 and the main fan blade 16 have opposite tilt angles, their rotation directions are also opposite. Therefore, when the rotation trend of the auxiliary fan blade 4 is to blow air upward, the rotating blade mechanism 5 also blows air upward. At the same time, when the rotating seat 11 is not stretched and lifted upward by the driving structure to drive the rotating structure, the main fan blade 16 and the auxiliary fan blade 4 are in a close-fitting state. Both sides of the main fan blade 16 and the auxiliary fan blade 4 are high-hardness blades. When the storage plate 9 is driven upward by the bump lifting structure, it will lift the waste on the upper end of the storage plate 9 to contact the auxiliary fan blade 4 and the rotating blade mechanism 5. Then, through the tearing force of the main fan blade 16 and the auxiliary fan blade 4 rotating in opposite directions and the shearing force of the blades, the waste can be further crushed, making it easier to completely incinerate.

[0021] In this embodiment, the rotating structure includes a gear 13, which is sleeved and fixedly connected to the outer side wall of the connecting shaft 12. A toothed rod 14 meshes with one side of the gear 13, and a rotating ring 15 is fixedly connected to the lower end of the toothed rod 14. The rotating ring 15 is rotatably connected to the upper end of the central cylinder 3.

[0022] Specifically, the area between the bottom of the incinerator 1 and the storage plate 9 is the incineration chamber, and an oxygenator is installed at the bottom of the incinerator 1 to supply oxygen to the chamber. When the auxiliary fan blade 4 and the main fan blade 16 do not need to cut the waste above the storage plate 9, and the storage plate 9 is accumulating waste, the gear 14 is longitudinally slidably connected in the cavity of the rotating seat 11. When the planetary gear structure is driven upward by the drive structure, it will drive the rotating seat 11 to rise together, and the upward rise of the rotating seat 11 will bring... The moving rack 14 slides longitudinally on the outer wall of the gear 13, thereby driving the gear 13 to rotate locally. At the same time, the rack 14 is restricted, and its movement distance can only allow the gear 13 to rotate 90 degrees, so that the tilt angle of the main fan blade 16 and the auxiliary fan blade 4 are consistent. Meanwhile, as the planetary gear structure drives the rotating blade mechanism 5 to rotate, the rotating ring 15 will also rotate accordingly, so that the rotating ring 15 rotates on the upper surface of the central cylinder 3, and the rotation directions of the central cylinder 3 and the rotating ring 15 are opposite. When the main fan blade 16 rotates and changes its tilt angle, the auxiliary fan blade 4 and the main fan blade 16, although at the same tilt angle, rotate in opposite directions. Therefore, the auxiliary fan blade 4 delivers air upward, while the main fan blade 16 delivers air downward. Because the rotating blade mechanism 5 is lifted upward by the drive structure, the rotating blade mechanism 5 and the main fan blade 16 are no longer in contact, but rather form an air cavity. Since the auxiliary fan blade 4 and the main fan blade 16 simultaneously deliver air to the center, the pressure in the central air cavity is greater than the normal pressure. Then, through the air outlet 45, the air inlet 46, and the flow box 2, the air in the air cavity can be delivered to the upper end of the storage plate 9, thereby using the residual heat in the incinerator 1 and the gas pipe 43 to dry the waste material at the upper end of the storage plate 9.

[0023] In this embodiment, the planetary gear structure includes an outer sleeve 21, which is fixedly connected to the upper end of the outer wall of the rotating seat 11. A gear ring 18 is fixedly connected to the cavity of the outer sleeve 21. A sun gear 17 is longitudinally slidably connected to the outer wall of the sleeve 6. A plurality of planet gears 19 mesh between the sun gear 17 and the gear ring 18. A positioning frame 20 is rotatably connected to the center of each planet gear 19, and the positioning frame 20 extends to the upper surface of the incinerator 1.

[0024] Specifically, the upper end of the outer sleeve 21 is equipped with a sealing plate to prevent smoke from entering the interior of the outer sleeve 21. The sealing plate is rotatably connected to the upper end of the outer sleeve 21. During the rotation of the sun gear 17 driven by the central cylinder 3 and the sleeve 6, the planetary gear 19 drives the gear ring 18 to rotate in the opposite direction. During this process, the positioning frame 20 provides positioning, so that the planetary gear 19 can only rotate. During the rotation of the gear ring 18, the outer sleeve 21 will be driven to rotate accordingly. Then, the outer sleeve 21 drives the lower vane mechanism 5 to rotate. The rotation speed of the sleeve 6 and the sun gear 17 is 1.5 times the rotation speed of the gear ring 18 and the vane mechanism 5. At the same time, the outer sleeve 21 and the sun gear 17 rotate. During the process, the sealing plate at the upper end of the outer jacket 21 and the positioning frame 20 remain in the same position. However, when the drive structure pulls the positioning frame 20 upward, the positioning frame 20 will drive the sealing plate to rise, which will then drive the outer jacket 21 and the rotating blade mechanism 5 to rise accordingly. At this time, the rack 14 on the rotating structure can be triggered to drive the gear 13 and the connecting shaft 12 to rotate, thereby causing the position of the main fan blade 16 to switch. At the same time, since the rotation speed of the central cylinder 3 is 1.5 times that of the rotating blade mechanism 5, when the air cavity is formed between the auxiliary fan blade 4 and the main fan blade 16, the gas will still be preferentially transported into the upper suction duct 7, thereby preventing the gas inside the incinerator 1 from having a serious backflow problem at the slot of the feed channel 30.

[0025] In this embodiment, the drive structure includes a cylinder 23, which is fixedly connected to the upper end of the incinerator 1. An L-shaped connecting rod 22 is fixedly connected to the output end of the cylinder 23, and the L-shaped connecting rod 22 is fixedly connected to the positioning frame 20. A gear ring 24 is sleeved on the outer side wall of the upper end of the drive shaft 8. A motor 26 is also fixedly connected to the upper end of the incinerator 1, and a gear 25 is fixedly connected to the output end of the motor 26, and the gear 25 meshes with the gear ring 24.

[0026] Specifically, the cylinder 23 drives the L-shaped connecting rod 22 to rise, and then the L-shaped connecting rod 22 drives the positioning frame 20 to rise, so that the positioning frame 20 can drive the planetary gear structure and the blade mechanism 5 to rise, thereby allowing the main fan blade 16 to switch rotation; The rotation of the central cylinder 3 and the sleeve 6 is achieved by the motor 26 driving the gear 25 to rotate, which in turn drives the gear ring 24 to rotate. The gear ring 24 then drives the drive shaft 8 to rotate, and the drive shaft 8 is fixedly connected to the sleeve 6. Therefore, the sleeve 6 and the central cylinder 3 rotate together, thereby driving the rotation of the auxiliary fan blade 4 and the main fan blade 16. At the same time, the rotation speed of the sleeve 6 and the central cylinder 3 can be precisely controlled by adjusting the speed of the motor 26, adapting to the crushing and drying needs of different types and moisture levels of waste, and improving the adaptability of the equipment.

[0027] In this embodiment, a flow box 2 is fitted on the outer wall of the incinerator 1. A sealing ring 27 is longitudinally slidably connected inside the cavity of the incinerator 1. The cavity of the flow box 2 is provided with a plurality of sliding seats 28 that are fixedly connected at equal intervals to the outer wall of the incinerator 1. A sliding rod 29 is installed in the cavity of the sliding seat 28 and is connected to the sealing ring 27. A feeding channel 30 is fixedly connected to the outer wall of the flow box 2, and one end of the feeding channel 30 is connected to the inner cavity of the incinerator 1.

[0028] Specifically, the central cylinder 3 is equipped with an external waste conveying device. This device is a conveying system housed within a sealed box, which is connected to the infeed channel 30. A program-controlled electrically operated door is located in the sealed box away from the infeed channel 30, with the door's opening directly above the conveying system. This allows for continuous, sealed feeding of waste, preventing dust spillage and gas leakage during the feeding process. A sliding plate is fixed to the outer wall of the sealing ring 27, and this plate can slide longitudinally along the outer wall of the sliding rod 29. When the storage plate... When the 9 is lifted upwards, its upper edge will abut against the lower end face of the sealing ring 27, thereby pushing the sealing ring 27 upwards along the sliding rod 29, so that its side wall completely covers the sealing air inlet 46, preventing the splashed material from flowing into the flow box 2 and causing air passage blockage when the auxiliary fan blade 4 and the main fan blade 16 are shearing waste. When all the waste on the storage plate 9 is discharged from the one-way groove 47, the storage plate 9 is lowered and reset, and the sealing ring 27 will slide down along the sliding rod 29 and reset due to its own weight, so that the air inlet 46 is unobstructed and the subsequent hot air drying process is carried out normally.

[0029] In this embodiment, several air outlets 45 are provided on the outer wall of the incinerator 1 directly above the storage plate 9, and several air inlets 46 are also provided on the outer wall of the incinerator 1 directly above the auxiliary fan blade 4. The air outlets 45 and air inlets 46 are connected through the flow box 2. Several one-way grooves 47 are provided at the upper end of the storage plate 9, and a one-way plate 10 is rotatably connected in the cavity of each one-way groove 47.

[0030] Specifically, torsion springs are installed at both ends of the one-way plate 10 and the one-way groove 47. During the stage when the auxiliary fan blade 4 and the main fan blade 16 are crushing the waste material at the top of the storage plate 9, the oxygen supply unit at the bottom of the incinerator 1 will not supply oxygen to the interior of the auxiliary fan blade 4. When no gas enters the interior of the incinerator 1, the torsion springs, combined with the one-way groove 47, will keep the one-way plate 10 in a horizontal position, thereby sealing the one-way groove 47 and preventing the flue gas in the incinerator from overflowing upwards. During the oxygen supply phase, when the oxygenator is feeding gas into the incinerator 1, the gas pushes the one-way plate 10 to rotate in the opposite direction, allowing the waste to enter the combustion chamber. The entry method is that the bumping and lifting structure lifts the storage plate 9 to the position directly below the auxiliary fan blade 4, where it is sheared by the auxiliary fan blade 4 and the main fan blade 16. At this time, the drive structure reduces the rotation speed of the sleeve 6, and the auxiliary fan blade 4 scrapes the waste on the upper surface of the storage plate 9, causing the waste above the storage plate 9 to be scraped to the position of the one-way groove 47. At the same time, the one-way plate 10 no longer blocks the one-way groove 47, so the waste falls into the bottom of the incinerator 1 for incineration. The bottom of the incinerator 1 also needs to be equipped with ash discharge equipment, which can be achieved by setting automatically opening and closing holes and scrapers at the bottom of the incinerator 1, so as to realize the continuous discharge of incineration ash and ensure the continuous operation of the equipment.

[0031] In this embodiment, the bumping and lifting structure includes a high-friction ring 33, which is disposed on the lower surface of the storage plate 9. A stainless steel spring 32 is fixedly connected to the lower end of the high-friction ring 33. A large gear ring 31 is fixedly connected to the lower surface of the stainless steel spring 32, and the lower surface of the large gear ring 31 is rotatably connected within the cavity of the incinerator 1. A second heat insulation cylinder 48 is fixedly connected to the lower end of the storage plate 9, and the second heat insulation cylinder 48 is longitudinally slidably connected to the cavity of the large gear ring 31. A frame 36 is installed on the outer wall of the incinerator 1. A second gear 34 is rotatably connected inside the frame 36, and the second gear 34 meshes with the large gear ring 31. A second motor 35 is fixedly connected to the lower end of the frame 36, and the output end of the second motor 35 is fixedly connected to the second gear 34.

[0032] In this embodiment, a threaded rod 37 is fixedly connected to the lower end of the central cylinder 3, and the threaded rod 37 is disposed in the cavity of the insulation cylinder 38. A threaded seat 42 is screwed onto the outer wall of the threaded rod 37. A coupling 41 is fixedly connected to the outer wall of the threaded seat 42. The upper end of the coupling 41 abuts against a coupling 40. A connecting cylinder 39 is fixedly connected to the upper end of the coupling 40, and the connecting cylinder 39 is fixedly connected to the lower surface of the storage plate 9. A smoke exhaust seat 44 is fixedly connected to the end of the gas pipe 43 away from the incinerator 1.

[0033] Specifically, when the central cylinder 3 is driven to rotate by the drive structure, it also drives the threaded rod 37 to rotate. During the rotation of the threaded rod 37, friction is generated on the threaded contact surface with the inner wall of the threaded seat 42. The contact surfaces of coupling one 40 and coupling two 41 are both single-sided bevel structures. When there is little waste on the upper surface of the storage plate 9, the force generated by the storage plate 9 pressing on coupling one 40 cannot stop the rotation of the threaded seat 42. Therefore, during this process, the rotation of the threaded rod 37 will drive the threaded seat 42 to rotate. Then, the rotation of the threaded seat 42 will drive the coupling two 41 to rotate, and the bevel will then cause coupling one 40 to rise upward until the weight of the waste at the upper end of the storage plate 9 reaches the target, causing coupling one 40 to rotate upward. The downward force restricts the rotation of coupling 41 and threaded seat 42. At this time, the rotation of threaded rod 37 will cause it to rotate with the inner wall of threaded seat 42, causing threaded seat 42 to rise. At the same time, threaded seat 42 will push coupling 40, connecting cylinder 39 and storage plate 9 to rise, thereby raising the waste to contact with auxiliary fan blade 4 and main fan blade 16. When storage plate 9 needs to be lowered, the waste at the top of storage plate 9 only needs to be discharged into the bottom of the incineration chamber 1. Then, the drive structure drives threaded rod 37 to rotate in the opposite direction. Then, coupling 41 rotates in the opposite direction, causing the contact surface with coupling 40 to be straight. At this time, during the reverse rotation of threaded rod 37, storage plate 9 will be lowered. The storage plate 9 can also rotate, ensuring that the waste material conveyed by the feed channel 30 to the storage plate 9 is evenly distributed. Specifically, motor 2 35 drives gear 2 34 to rotate, then gear 2 34 drives the large gear ring 31 to rotate, which in turn drives the stainless steel spring 32 and the high-friction ring 33 to rotate. Finally, the high-friction ring 33 drives the storage plate 9 to rotate together through the friction of its contact surface with the storage plate 9. The resistance to the rotation of the storage plate 9 is relatively large. During the rotation, the stainless steel spring 32 will tighten and press down appropriately. At the same time, the stainless steel spring 32 also plays a certain supporting role for the storage plate 9, ensuring that the storage plate... When the waste material at the top of plate 9 reaches a certain weight standard, sufficient downward pressure can be applied to compress the stainless steel spring 32 while simultaneously allowing coupling 40 to abut against coupling 41, preventing coupling 41 from rotating. During the feeding process onto the upper part of the storage plate 9, the rotation direction of the storage plate 9 is the same as that of the threaded rod 37, but the rotation speed of the storage plate 9 is slower than that of the threaded rod 37. Therefore, even when coupling 40 rotates along with the storage plate 9, it will still be lifted upwards by coupling 41. Simultaneously, when coupling 41 pushes coupling 40 upwards, the storage plate 9 will be lifted during this process. This causes a brief separation of the high-friction ring 33, reducing the friction between them. At this point, the elastic potential energy generated by the twisting of the stainless steel spring 32 returns to its original position, pushing the storage plate 9 further upward. During this process, the waste material at the top of the storage plate 9 is jolted and lifted. As the storage plate 9 rises, it also partially blocks and reduces the size of the holes in the air outlet 45, thus increasing the wind speed generated by the air outlet 45. Because the waste material at the top of the storage plate 9 is jolted and lifted, the stronger airflow can better penetrate the waste material, thereby drying it. When the weight at the top of the storage plate 9 reaches the target, then... This will cause the storage plate 9 to rise further, and then the storage plate 9 will separate from the high friction ring 33. The second heat insulation cylinder 48 is used to prevent the internal temperature of the incinerator 1 from being too high and affecting the performance of the stainless steel spring 32. It plays the role of isolating the internal temperature of the incinerator 1. The stainless steel spring 32 is made of 310S high temperature resistant austenitic stainless steel, which can withstand the working environment of 650℃ for a long time and can withstand the high temperature of 800℃ for a short time. It is suitable for the high temperature conditions inside the incinerator. The second heat insulation cylinder 48 adopts a high temperature resistant composite structure, which can isolate the high temperature of the incineration chamber and ensure the stability of the elastic performance of the stainless steel spring 32, so as to achieve long-term stable use of both in the incinerator 1.

[0034] Working principle: When this device is working, the waste is first transported to the storage plate 9 in the incineration box 1 through the feeding channel 30. The motor 26 starts and drives the drive shaft 8 to rotate through the meshing of the gear 25 and the gear ring 24. This drives the sleeve 6 and the central cylinder 3 to rotate synchronously. The central cylinder 3 drives the auxiliary fan blade 4 to rotate. At the same time, the sleeve 6 drives the rotating seat 11 to rotate in the opposite direction to the main fan blade 16 through the planetary gear structure. At this time, the main fan blade 16 and the auxiliary fan blade 4 are at a symmetrical tilt angle. The two rotate in opposite directions to form an upward negative pressure. Through the suction pipe 7, a continuous suction effect is formed to prevent the flue gas in the incineration chamber from flowing back into the feeding channel 30. When the weight of the material on the storage plate 9 reaches the target, coupling 1 40 presses down to restrict coupling 2 41 and threaded seat 42 from rotating. The central cylinder 3 drives the threaded rod 37 to rotate, which drives the threaded seat 42 to rise through the threaded transmission, thereby pushing the storage plate 9 to move upward. At the same time, motor 2 35 starts and drives the large gear ring 31 to rotate through gear 2 34. In conjunction with the stainless steel spring 32 and the high friction ring 33, the storage plate 9 rotates. The release of the elastic potential energy of the stainless steel spring 32 causes the storage plate 9 to bump, making the material loose. The cylinder 23 drives the positioning frame 20 to rise upward through the L-shaped connecting rod 22, which in turn drives the rotating blade mechanism 5 to move upward, triggering the rotating structure to drive the main fan blade 16 to rotate 90 degrees, so that the main fan blade 16 and the auxiliary fan blade 4 have the same tilt angle. At this time, the two rotate in opposite directions to form a circulating air path. The residual heat of the combustion chamber is used to deliver hot air to the material on the storage plate 9 through the air outlet 45, the flow box 2, and the air inlet 46. The material is dried evenly by the bumping of the storage plate. After drying, cylinder 23 drives positioning frame 20 to reset, main fan blade 16 returns to its original angle, and storage plate 9 continues to rise, so that the material comes into contact with main fan blade 16 and auxiliary fan blade 4. The two rotate in opposite directions, and the waste is crushed by the shearing and tearing force of the blades. After crushing, oxygen is supplied to the incineration chamber by the oxygen supply unit, which pushes the one-way plate 10 to open. The auxiliary fan blade 4 rotates and scrapes the crushed material into the incineration chamber through the one-way groove 47 for incineration. The flue gas generated by incineration is discharged through gas pipe 43 and flue gas seat 44 for subsequent purification. After the material is discharged, motor 26 drives threaded rod 37 to rotate in the opposite direction, driving storage plate 9 to fall and reset, completing one feeding cycle. This process is repeated to realize continuous feeding, pretreatment and incineration of waste.
