Description

Technical Field

[0001] This invention relates to the field of waste incineration technology, specifically to a waste incineration grate feeding and propulsion device. Background Technology

[0002] Garbage is a pollutant generated by human production activities. Large amounts of waste pose a great threat to the environment, mainly by encroaching on land, polluting the atmosphere, soil and water, and the damage caused is difficult to restore. At present, there are various incinerator structures used to solve urban domestic waste, with grate incinerators being the most commonly used. A grate incinerator is a garbage incinerator equipped with a grate that can move combustibles.

[0003] According to the patent announcement "CN119436150A" published on the China Patent Network, entitled "A Fixed Grate Incinerator," it includes a warm air box, a placement box fixedly connected to the top of the warm air box, a feeding plate rotatably connected to both sides of the inner wall of the placement box via a rotating shaft, a discharge chamber fixedly connected to the right side of the placement box, a warm air pipe fixedly connected to the bottom of the inner wall of the warm air box, and the top of the warm air pipe fixedly connected to the inner wall of the placement box. It also includes a cutting mechanism, including a dropping plate fixedly connected to the left side of the inner wall of the placement box, and a rotating cavity fixedly connected to the bottom of the inner wall of the dropping plate. By setting up the cutting mechanism, a negative pressure suction is generated inside the absorption bag, and the absorption plate contacts the surface of the waste, thereby absorbing the moisture in the waste into the interior of the folded belt. This can cut a gap in some sealed packaged waste and absorb excess moisture from the surface of the waste, improving the subsequent evaporation efficiency of the moisture inside the waste.

[0004] While the aforementioned patents can absorb excess moisture and improve evaporation efficiency, the incinerator requires continuous feeding during operation, resulting in a large amount of waste accumulating near the feeding location for an extended period. This reduces the surface area of ​​the waste in contact with air during combustion, ultimately leading to reduced incineration efficiency. To address this issue, we provide a waste incinerator grate feeding and propulsion device. Summary of the Invention

[0005] The purpose of this invention is to provide a waste incinerator grate feeding and propulsion device to solve the problem that waste accumulates near the feeding position for a long time, thereby reducing the contact area between waste and air during incineration and ultimately reducing the efficiency of waste incineration.

A feeder is provided on the top of the flipping fixed plate.

[0009] As a further embodiment of the present invention: the material spreading mechanism further includes a material spreading arc-shaped toothed plate fixedly connected to the inside of the furnace body, and a flipping toothed shaft is meshed with the outer wall of the material spreading arc-shaped toothed plate.

The sealing ring abuts against the opening of the arc-shaped groove, and the arc-shaped groove matches the flipping connecting rod.

[0010] As a further embodiment of the present invention: the material turning mechanism includes a material turning motor fixedly connected to the inside of the furnace body, and a material turning gear shaft fixedly connected to the output end of the material turning motor. A material turning gear ring is meshed with the outer wall of the material turning gear shaft, and a material turning arc plate is fixedly connected to the inner wall of the material turning gear ring. A bearing arc plate is slidably connected to the inner wall of the material turning arc plate, and one side of the bearing arc plate is fixedly connected to one side of the mounting frame. A material turning sealing plate is fixedly connected to the other side of the bearing arc plate, and an auxiliary sealing component is provided on one side of the material turning arc plate.

[0013] As a further embodiment of the present invention: the feeding mechanism further includes a connecting rod fixedly connected to one side of the feeding push plate, and the other end of the connecting rod is fixedly connected to a movable sealing plate. The feeding push plate and the movable sealing plate are both slidably connected inside the flipping arc plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Through the coordination of components such as the material spreading mechanism, the waste can be slowly and continuously fed on the conveyor belt and feeder, allowing for initial combustion. This process evaporates the moisture inside the initially burning waste, facilitating subsequent full combustion. The rotating extension threaded rod drives the extension plate to move linearly into the tilting and fixing plate. As the extension plate tilts, it moves linearly into the tilting and fixing plate, evenly spreading the waste on top onto the inner side of the supporting arc plate for secondary combustion. This avoids oxygen deficiency caused by local accumulation and increases the contact area between the waste and air. Through the above operations, the waste combustion is continuous, preventing waste from accumulating in one place and thus improving the efficiency of subsequent waste incineration.

[0016] 2. By coordinating components such as the tipping mechanism, the unloading mechanism can push down some of the burned waste from the top of the supporting arc plate for unloading. When new waste to be burned is laid on top of the supporting arc plate, the rotating supporting arc plate can push the waste at the bottom, flipping over the unburned waste at the bottom to the top of the newly laid waste. This allows the unburned waste to cover the new waste for rapid combustion. The newly laid waste can be preheated and burned at the bottom of the unburned waste. During the combustion process, the unburned waste covers the waste. When the waste is above the unburned waste, its residual heat and combustibles can directly contact oxygen and continue to burn, avoiding the waste of heat and the residue of combustibles caused by incomplete combustion. The new waste is preheated below the unburned waste, and its temperature rises rapidly to the ignition point, reducing the energy consumption from room temperature to combustion state, shortening the combustion start-up time, and making the overall combustion process more efficient. The residual heat of the unburned waste is directly transferred to the new waste below, forming a heat cycle of "upper layer combustion and heat release - lower layer heat absorption and preheating", reducing the loss of heat from the furnace to the outside and improving the thermal energy utilization rate.

[0017] 3. Through the coordination of components such as the feeding mechanism, the feeding motor drives the flipping fixed plate to reset, thereby pushing the toothed plate to move linearly, which in turn drives the feeding push plate to move linearly. The linearly moving feeding push plate drives the movable sealing plate to move linearly through the connecting rod. The feeding push plate can push the incineration ash through the gap between the movable sealing plate and the flipping sealing plate and move it out of the bearing arc plate, realizing the automation of the ash discharge process of the waste incinerator and achieving efficient, energy-saving and low-emission ash treatment.

[0033] Please see Figures 1-12This embodiment provides a feeding and propulsion device for a waste incinerator grate furnace, comprising: a furnace body 1, a feeding trough 2 fixedly connected to one side of the furnace body 1, a vertical combustion box 3 fixedly connected to the top of the furnace body 1, an inclined combustion box 4 fixedly connected to the other side of the furnace body 1, a mounting frame 5 fixedly connected inside the furnace body 1, a conveying mounting base 6 fixedly connected to the outside of the furnace body 1, a conveying motor 7 fixedly connected to the top of the conveying mounting base 6, a conveying roller 39 and a driven roller 40 rotatably connected to the inside of the furnace body 1, and a conveyor belt 8 installed on the outer wall of the conveying roller 39 and the driven roller 40, the output end of the conveying motor 7 penetrating through the furnace body. The furnace body 1 is fixedly connected to the inner side of the furnace body 1 and to the conveyor roller 39. A material spreading mechanism is provided inside the furnace body 1 near the conveyor belt 8. A material feeding mechanism is provided on the top of the mounting frame 5. A material turning mechanism is provided inside the mounting frame 5 away from the conveyor belt 8. The material spreading mechanism includes a material spreading mounting base 9 fixedly connected to the inner side of the furnace body 1. A material spreading motor 10 is fixedly connected to the top of the material spreading mounting base 9. A material spreading rotating rod 11 is fixedly connected to the output end of the material spreading motor 10. One end of the material spreading rotating rod 11 passes through the inner side of the mounting frame 5 and is rotatably connected to the mounting frame 5. A flipping fixing plate is fixedly connected to the outer wall of the material spreading rotating rod 11 inside the mounting frame 5. 12. A flipping connecting rod 13 is rotatably connected to the inner side of the flipping fixing plate 12, and one end of the flipping connecting rod 13 extends through to the outside of the flipping fixing plate 12 and is fixedly connected to a flipping gear shaft 14. A sealing ring 20 is fixedly connected to the outer wall of the flipping connecting rod 13 near the outer wall of the flipping fixing plate 12, and the sealing ring 20 is rotatably connected to the inner side of the furnace body 1. The material spreading mechanism also includes a first bevel gear 16 fixedly connected to the other end of the flipping connecting rod 13, and a second bevel gear 17 is meshed with the outer wall of the first bevel gear 16. An extension threaded rod 18 is fixedly connected to one side of the second bevel gear 17, and the outer wall of the extension threaded rod 18 is threaded. An extension plate 19 is connected, and the outer wall of the extension plate 19 is slidably connected to the inside of the flipping fixing plate 12. The inner side of the flipping fixing plate 12 is provided with a limiting groove that matches the extension plate 19. A feeder 21 is provided on the top of the flipping fixing plate 12. The material spreading mechanism also includes a material spreading arc-shaped toothed plate 15 fixedly connected to the inside of the furnace body 1. The outer wall of the material spreading arc-shaped toothed plate 15 is meshed with a flipping toothed shaft 14. One end of the flipping connecting rod 13 extends through to the outside of the furnace body 1. An arc-shaped groove communicating with the inside is provided on the outside of the furnace body 1. The sealing ring 20 abuts against the opening of the arc-shaped groove, and the arc-shaped groove matches the flipping connecting rod 13.

[0034] The material turning mechanism includes a material turning motor 22 fixedly connected inside the furnace body 1, and a material turning gear shaft 23 fixedly connected to the output end of the material turning motor 22. A material turning gear ring 24 is meshed with the outer wall of the material turning gear shaft 23, and a material turning arc plate 25 is fixedly connected to the inner wall of the material turning gear ring 24. A bearing arc plate 26 is slidably connected to the inner wall of the material turning arc plate 25, and one side of the bearing arc plate 26 is fixedly connected to one side of the mounting frame 5. A material turning sealing plate 27 is fixedly connected to the other side of the bearing arc plate 26. An auxiliary closing assembly is provided on one side of the arc plate 25. The auxiliary closing assembly includes two auxiliary mounting seats 28 symmetrically installed on one side of the flipping arc plate 25. An auxiliary rotating rod 37 is rotatably connected inside the flipping arc plate 25. One end of the auxiliary rotating rod 37 extends through to the outside of the flipping arc plate 25 and is rotatably connected to the auxiliary mounting seat 28. An auxiliary flipping plate 30 is fixedly connected to the outer wall of the auxiliary rotating rod 37. A torsion spring 29 is installed between the auxiliary mounting seat 28 and the auxiliary flipping plate 30.

[0035] The feeder 21 includes components such as a feeder motor, a feeder fixed seat, a feeder rotating rod, and a feeder conveyor belt. Since it is existing technology, this solution does not specifically describe how to achieve feeding. When the garbage falls to the top of the feeder 21 through the conveyor belt 8, the feeder 21 can drive the garbage to continuously fall to the top of the extension plate 19, avoiding the accumulation of garbage on one side of the flipping fixed plate 12, which prevents effective feeding.

[0036] The combustion operation of the vertical combustion box 3 and the inclined combustion box 4 is existing technology, so it is not described in detail in this solution. The flame temperature ejected from the vertical combustion box 3 is lower than that ejected from the inclined combustion box 4.

[0037] Before incineration, the waste is fed into the feeding trough 2. At this time, the vertical combustion box 3 is started. The vertical combustion box 3 can spray the flame vertically downward toward the conveyor belt 8. Then the conveyor motor 7 is started. The conveyor motor 7 drives the conveyor roller 39 to rotate, thereby driving the conveyor belt 8 to rotate. The rotating conveyor belt 8 can carry the waste in the feeding trough 2 to the feeder 21. During the transportation process, the flames sprayed from the top vertical combustion box 3 can evaporate the moisture in the waste, thereby improving the subsequent combustion efficiency.

[0038] When the waste is transported to the tilting fixing plate 12, the spreading motor 10 is started. The spreading motor 10 drives the spreading rotating rod 11 to drive the tilting fixing plate 12 to perform a reciprocating tilting motion (swinging back and forth at 10-60 degrees, with the tilting fixing plate 12 initially tilted). The tilting fixing plate 12 drives the extension plate 19 to tilt, causing the extension plate 19 to move closer to the mounting frame 5 from away from it. The tilting fixing plate 12, through the tilting connecting rod 13, drives the tilting gear shaft 14 to perform a circular motion. The circularly moving tilting gear shaft 14 rotates through meshing with the spreading arc-shaped toothed plate 15, thereby driving the first bevel gear 16 through the spreading rotating rod 11. The rotation of the first bevel gear 16, through meshing with the second bevel gear 17, drives the extension threaded rod 18 to rotate. The rotating extension threaded rod 18 drives the extension plate 19 to move linearly into the flipping fixed plate 12 through the thread action. While the extension plate 19 flips towards the mounting frame 5, it moves linearly into the flipping fixed plate 12, which can evenly spread the garbage on the top to the inner side of the bearing arc plate 26 for concentrated combustion, avoiding oxygen deficiency combustion caused by local accumulation, increasing the contact area between garbage and air, accelerating the release of volatiles, and reducing unburned residue. Through the above operation, the garbage combustion is continuous, avoiding garbage accumulation in one place, thereby improving the efficiency of subsequent garbage incineration.

[0039] After the waste is evenly spread from the extension plate 19 onto the top of the supporting arc plate 26, the turning motor 22 is started. The turning motor 22 drives the turning gear shaft 23 to rotate. The rotating turning gear shaft 23, through meshing, drives the turning arc plate 25 to rotate around the supporting arc plate 26 via the turning gear ring 24 (the turning arc plate 25 rotates within a range of 0-60 degrees). The rotating supporting arc plate 26 can push the waste at the bottom, turning over the unburned waste at the bottom to the top of the waste. By continuously adjusting the waste at the bottom to the top of the newly laid waste, the unburned waste can be covered on top of the new waste for rapid incineration. The newly laid waste can... The unburned waste at the bottom is preheated and burned. During the combustion process, when the unburned waste covers the new waste, its residual heat and combustibles can directly contact oxygen and continue to burn. This avoids the waste of heat and the residue of combustibles caused by incomplete combustion. The new waste is preheated under the unburned waste, and its temperature rises rapidly to the ignition point, reducing the energy consumption from room temperature to combustion state, shortening the combustion start-up time, and making the overall combustion process more efficient. The residual heat of the unburned waste is directly transferred to the new waste below, forming a heat cycle of "upper layer combustion and heat release - lower layer heat absorption and preheating", reducing the loss of heat from the furnace to the outside and improving the thermal energy utilization rate.

[0040] Before the material-turning arc plate 25 rotates, the auxiliary turning plate 30 is offset towards the inner wall of the furnace body 1 by the torsion spring 29, which can avoid blocking the turning of the extension plate 19. When the material-turning arc plate 25 rotates, it can drive the auxiliary turning plate 30 to perform a circular motion. During the circular motion, the auxiliary turning plate 30 contacts the bearing arc plate 26, which can drive the auxiliary turning plate 30 to rotate around the auxiliary rotating rod 37. After the auxiliary turning plate 30 rotates, it matches the curvature of the material-turning arc plate 25 and can rotate with the material-turning arc plate 25. When the material-turning arc plate 25 rotates away from its original position, it accurately fills the gap formed between the auxiliary turning plate 30 and the bearing arc plate 26, which can prevent garbage from accumulating in the material-turning dead corner and prevent the connecting machine from getting stuck in the gap, causing the device to stop.

[0041] An arc groove matching the bearing arc plate 26 is provided between the flipping arc plate 25 and the flipping toothed ring 24 so that the flipping arc plate 25 and the flipping toothed ring 24 can rotate along the outer wall of the bearing arc plate 26.

[0042] Please see Figures 10-11 The feeding mechanism includes a feeding fixing frame 38 fixedly connected to the top of the mounting frame 5, and a feeding gear shaft 32 rotatably connected inside the feeding fixing frame 38. A feeding arc-shaped gear plate 31 is meshed with the outer wall of one side of the feeding gear shaft 32, and the top of the feeding arc-shaped gear plate 31 is fixedly connected to the bottom of the flipping fixing plate 12. A pushing gear plate 33 is meshed with the bottom of the other side of the feeding gear shaft 32, and a feeding push plate 34 is fixedly connected to the end of the pushing gear plate 33. The feeding mechanism also includes a connecting rod 35 fixedly connected to one side of the feeding push plate 34, and a movable sealing plate 36 is fixedly connected to the other end of the connecting rod 35. The feeding push plate 34 and the movable sealing plate 36 are both slidably connected inside the flipping arc-shaped plate 25.

[0043] After the tilting fixed plate 12 evenly spreads the garbage on the top of the bearing arc plate 26 through the extension plate 19, the tilting combustion box 4 is started. After the garbage is burned for a period of time (meaning that the garbage at the top is completely burned), the turning motor 22 is turned off. The spreading motor 10 drives the tilting fixed plate 12 to reset. The reset of the tilting fixed plate 12 drives the feeding arc toothed plate 31 to tilt. The tilting feeding arc toothed plate 31 drives the pushing toothed plate 33 to move linearly towards the bearing arc plate 26 through the feeding toothed shaft 32. The pushing toothed plate 33 moves linearly and drives the feeding push plate 34 to move linearly. The linearly moving feeding push plate 34 drives the movable sealing plate 36 to move linearly through the connecting rod 35. The feeding push plate 34 can push the incinerated ash through the gap between the movable sealing plate 36 and the tilting sealing plate 27 and move it out of the bearing arc plate 26. This realizes the automation of the ash discharge process of the garbage incinerator and achieves efficient, energy-saving and low-emission ash treatment.

[0044] Inside the furnace body 1, below the supporting arc plate 26, there is a slag discharge port for collecting ash and slag produced by the combustion of waste. The slag discharge port inlet is located on one side of the turning sealing plate 27, so that the ash and slag after combustion can fall into the slag discharge port during the process of being pushed by the feeding push plate 34, so that the staff can remove it later.

[0045] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art of small furnaces who makes equivalent substitutions or changes based on the technical solution and inventive concept of the present invention within the scope of the technology disclosed in the present invention should be covered within the scope of protection of the present invention.
