Description

Technical Field

[0001] The present invention belongs to the technical field of waste treatment equipment, and particularly relates to an incinerator for pyrolysis gasification incineration treatment of domestic waste. Background Art

[0002] A domestic waste pyrolysis gasification incinerator is an efficient and environmentally friendly device specifically used for treating urban domestic waste. It converts domestic waste into combustible gas and other useful products through a high-temperature pyrolysis process, while reducing the volume of waste and its impact on the environment.

[0003] When traditional domestic waste pyrolysis gasification incinerators are used to treat domestic waste, it is necessary to manually open the furnace door of the incinerator and then shovel the domestic waste into the incinerator. This is not a problem when adding domestic waste to the incinerator for the first time, but when adding domestic waste again after the incinerator is running, not only a large amount of heat in the incinerator is lost, but also the operator needs to bear the high temperature radiated inside the incinerator. At the same time, the shoveled domestic waste accumulates near the entrance of the incinerator, and the domestic waste is unevenly heated, and more energy needs to be wasted to ensure the full pyrolysis of domestic waste. In addition, it is inconvenient to handle the slag of traditional domestic waste pyrolysis gasification incinerators. It is necessary to open the incinerator to handle the slag after the domestic waste is processed, and the use is relatively troublesome. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide an incinerator for pyrolysis gasification incineration treatment of domestic waste. The present invention can automatically open the incineration chamber. The operator only needs to add domestic waste from above the incineration chamber without facing the high-temperature radiation of the incineration chamber. At the same time, the domestic waste is uniformly fed into the pusher mechanism after being crushed by the feeding mechanism, and then pushed into the incineration chamber by the pusher mechanism. This not only effectively reduces the volume of domestic waste and increases the amount of domestic waste fed at one time, but also the waste is evenly distributed in the pusher mechanism, without wasting a large amount of energy to pyrolyze domestic waste, effectively saving energy. Moreover, the slag generated in the incineration chamber can be timely processed by the slag discharging mechanism, and the use is convenient.

[0005] The technical solution adopted to solve the above technical problem is: an incinerator for pyrolysis gasification incineration treatment of domestic waste, including an incineration chamber and a pusher mechanism. The pusher mechanism is slidably connected in the incineration chamber. The front side of the top of the incineration chamber is slidably connected with a feeding mechanism. The top of the incineration chamber is slidably connected with a transmission mechanism. The bottom of the incineration chamber is fixedly provided with a slag discharging mechanism. The top of the incineration chamber is fixedly connected with a secondary combustion chamber. The top of the secondary combustion chamber is fixedly connected with a tail gas treatment device. The side of the incineration chamber is fixedly connected with a burner;

[0006] The pusher mechanism can drive the transmission mechanism when sliding in the incineration chamber, and the transmission mechanism can drive the feeding mechanism to slide horizontally left and right on the top of the incineration chamber;

[0007] The bottom of the secondary combustion chamber is communicated with the incineration chamber, the top of the secondary combustion chamber is communicated with the tail gas treatment device, and the burner is communicated with the incineration chamber.

[0008] Through the above technical solution, during operation, the pusher mechanism is opened, and the operator throws domestic waste into the feeding mechanism from above the incineration chamber. During the opening and closing of the pusher mechanism, the transmission mechanism can be driven. The transmission mechanism drives the feeding mechanism to slide horizontally left and right on the top of the incineration chamber, so that the domestic waste in the feeding mechanism is evenly scattered onto the pusher mechanism, and then the pusher mechanism is pushed into the incineration chamber. The burner is started to pyrolyze the domestic waste entering the incineration chamber at high temperature. The domestic waste evenly scattered into the pusher mechanism avoids the problem of garbage accumulation near the entrance during traditional manual feeding, effectively reducing the energy required for the pyrolysis of domestic waste. The combustible gas generated by pyrolysis enters the secondary combustion chamber, and the combustible gas burns fully in the secondary combustion chamber to remove most of the harmful substances. At the same time, a heat exchange device can be connected to the secondary combustion chamber to make full use of the heat generated by the full combustion of the combustible gas in the secondary combustion chamber. Subsequently, the flue gas generated by combustion in the secondary combustion chamber is introduced into the tail gas treatment device, and the flue gas treated by the tail gas treatment device can be discharged up to standard into the atmosphere.

[0009] Furthermore, electric push rods are symmetrically and fixedly connected to both sides of the incineration chamber, and the tops of the electric push rods are fixedly connected to the pusher mechanism.

[0010] Through the above technical solution, since electric push rods are symmetrically and fixedly connected to both sides of the incineration chamber, and the tops of the electric push rods are fixedly connected to the pusher mechanism, the electric push rods can drive the pusher mechanism to slide horizontally in the incineration chamber, realizing the automatic opening and closing of the pusher mechanism, and effectively reducing the operation difficulty of the operator.

[0011] Furthermore, the pusher mechanism includes a material receiving frame, a movable material receiving grille and vibration components. The tops of the electric push rods are fixedly connected to the material receiving frame. The movable material receiving grille is vertically slidably connected in the material receiving frame. There are multiple vibration components, and the vibration components are symmetrically and rotatably connected to both sides of the material receiving frame.

[0012] Through the above technical solution, since the movable material receiving grille is vertically slidably connected in the material receiving frame and there are multiple vibration components symmetrically and rotatably connected to both sides of the material receiving frame, the vibration components can drive the movable material receiving grille to slide vertically in the material receiving frame.

[0013] Furthermore, a fixed material receiving grille is fixedly connected to the bottom of the incineration chamber, and the movable material receiving grille can be inserted into the fixed material receiving grille.

[0014] Through the above technical scheme, since a fixed receiving grille is fixedly connected to the bottom of the incineration chamber, the movable receiving grille can be inserted into the fixed receiving grille, so that after the pushing mechanism enters the incineration chamber, the movable receiving grille and the fixed receiving grille can form an integral receiving chassis, so that domestic garbage can be pyrolyzed at high temperature on it. After the pushing mechanism is pulled out of the incineration chamber, the slag produced after the high-temperature pyrolysis of the domestic garbage can fall through the gaps in the fixed receiving grille, and the slag can be discharged quickly and conveniently, making room for the domestic garbage to enter the incineration chamber again, simplifying the operation difficulty for the operator.

[0015] Furthermore, the vibration component includes a toggle wheel and a first gear, the toggle wheel is arranged below the movable material receiving grid, avoidance grooves are arranged on both sides of the fixed material receiving grid, the avoidance grooves allow the first gear to pass through, a first rack is arranged at the bottom of the avoidance groove, and the first gear is meshed with the first rack.

[0016] Through the above technical solution, since the vibration component includes a toggle wheel and a first gear, the toggle wheel is arranged below the movable material receiving grille, avoidance grooves are arranged on both sides of the fixed material receiving grille, the avoidance grooves allow the first gear to pass through, and a first rack is arranged at the bottom of the avoidance groove, and the first gear is meshed with the first rack, so that when the pushing mechanism slides horizontally in the incineration chamber, the first rack drives the first gear to rotate, the first gear drives the vibration component to rotate, and the rotation of the vibration component drives the toggle wheel to rotate, thereby driving the movable material receiving grille to slide vertically back and forth in the material receiving frame, thereby realizing the vibration of the movable material receiving grille;

[0017] When the pushing mechanism is pulled out of the incineration chamber, the vibration of the movable material-bearing grid can drive the slag produced by high-temperature pyrolysis in the incineration chamber to vibrate, thereby accelerating the slag to fall from the gap on the fixed material-bearing grid and accelerating the discharge of the slag;

[0018] At the same time, when the feeding mechanism scatters new domestic waste into the pushing mechanism, the vibration of the movable material receiving grid can further help the domestic waste to be evenly distributed on the movable material receiving grid, prevent the accumulation of domestic waste, make the domestic waste evenly heated during high-temperature pyrolysis, and reduce energy waste.

[0019] Furthermore, the feeding mechanism includes a hopper, a first feeding roller, a second feeding roller, a driving motor and a transmission ring. A first track is fixedly arranged on the front side of the top of the incineration chamber. The hopper is slidably connected to the first track. The first feeding roller and the second feeding roller are symmetrically rotatably connected in the hopper. The driving motor is fixedly connected to one side of the hopper. The transmission ring is fixedly connected to the rear side of the hopper. A second track is arranged on the top of the incineration chamber. The transmission ring is slidably connected to the second track. A sealing plate is fixedly connected to the top of the pushing mechanism, and the sealing plate can seal the bottom of the hopper.

[0020] Through the above technical solution, since the front side of the top of the incineration chamber is fixedly provided with a first track, the aggregate hopper is slidably connected to the first track, the first feeding roller and the second feeding roller are symmetrically rotatably connected in the aggregate hopper, the driving motor is fixedly connected to one side of the aggregate hopper, the transmission ring is fixedly connected to the rear side of the aggregate hopper, the top of the incineration chamber is provided with a second track, the transmission ring is slidably connected to the second track, the top of the pushing mechanism is fixedly connected with a blocking plate, and the blocking plate can block the bottom of the aggregate hopper, so that the horizontal left and right sliding of the transmission ring on the second track can drive the aggregate hopper to horizontally slide left and right on the first track. The setting of the blocking plate makes that when the pushing mechanism is closed, the blocking plate blocks the bottom of the aggregate hopper to prevent the domestic waste in the aggregate hopper from leaking. When the pushing mechanism is opened, the blocking plate leaves the bottom of the aggregate hopper, and the domestic waste in the aggregate hopper can fall into the pushing mechanism.

[0021] Further, a plurality of cutters are staggered on the first feeding roller and the second feeding roller. A driven gear is fixedly connected to one side of the first feeding roller, a driving gear is fixedly connected to one side of the second feeding roller, the driven gear meshes with the driving gear, and the driving motor can drive the second feeding roller to rotate.

[0022] Through the above technical solution, since a plurality of cutters are staggered on the first feeding roller and the second feeding roller, a driven gear is fixedly connected to one side of the first feeding roller, a driving gear is fixedly connected to one side of the second feeding roller, the driven gear meshes with the driving gear, and the driving motor can drive the second feeding roller to rotate. When the driving motor drives the second feeding roller to rotate, the driving gear rotates, and the rotation of the driving gear can drive the driven gear to rotate. The rotation of the driven gear can drive the first feeding roller to rotate, and the first feeding roller and the second feeding roller can rotate towards each other, so that the domestic waste put into the aggregate hopper can be sent below the aggregate hopper by the first feeding roller and the second feeding roller, and the staggered cutters can crush the domestic waste put into the aggregate hopper while sending it below the aggregate hopper.

[0023] Further, the transmission mechanism includes a first transmission component, a second transmission component and a transmission chain. The first transmission component and the second transmission component are both rotatably connected to the top of the incineration chamber. The second transmission component is arranged inside the transmission ring. A first transmission wheel is arranged on the first transmission component, a second transmission wheel is arranged on the second transmission component, and the first transmission wheel and the second transmission wheel are connected by a transmission chain.

[0024] Through the above technical solution, since both the first transmission component and the second transmission component are rotatably connected to the top of the incineration chamber, the second transmission component is arranged within the transmission circle, a first transmission wheel is arranged on the first transmission component, a second transmission wheel is arranged on the second transmission component, and the first transmission wheel and the second transmission wheel are connected by a transmission chain, the rotation of the first transmission wheel can drive the rotation of the second transmission wheel, that is, the rotation of the first transmission component can drive the rotation of the second transmission component.

[0025] Furthermore, a second rack is fixedly connected to the top of the pusher mechanism, a transmission gear is arranged on the first transmission component, the transmission gear meshes with the second rack, a first transmission rack is arranged on the front side within the transmission circle, a second transmission rack is arranged on the rear side within the transmission circle, a sector gear is arranged on the second transmission component, and the sector gear can mesh with the first transmission rack or the second transmission rack.

[0026] Through the above technical solution, since a second rack is fixedly connected to the top of the pusher mechanism, a transmission gear is arranged on the first transmission component, the transmission gear meshes with the second rack, a first transmission rack is arranged on the front side within the transmission circle, a second transmission rack is arranged on the rear side within the transmission circle, a sector gear is arranged on the second transmission component, and the sector gear can mesh with the first transmission rack or the second transmission rack, when the pusher mechanism horizontally slides within the incineration chamber, the second rack can drive the transmission gear to rotate, the rotation of the transmission gear can drive the first transmission component to rotate, and the rotation of the first transmission component can drive the second transmission component to rotate;

[0027] The rotation of the second transmission component can drive the rotation of the sector gear, and the rotation of the sector gear can intermittently and cyclically mesh with the first transmission rack and the second transmission rack, so that the transmission circle horizontally slides left and right reciprocally on the second track.

[0028] Furthermore, the slag discharge mechanism includes a slag collection hopper and a slag discharge frame. The top of the slag collection hopper is communicated with the incineration chamber. A slag collection bin is arranged at the bottom of the slag collection hopper. The slag discharge frame is slidably connected within the slag collection bin, and a handle is fixedly connected to one side of the slag discharge frame.

[0029] Through the above technical solution, since the slag discharge mechanism includes a slag collection hopper and a slag discharge frame, the top of the slag collection hopper is communicated with the incineration chamber, a slag collection bin is arranged at the bottom of the slag collection hopper, the slag discharge frame is slidably connected within the slag collection bin, and a handle is fixedly connected to one side of the slag discharge frame, when the pusher mechanism is opened, the slag that drops into the incineration chamber can enter the slag collection hopper and finally enter the slag discharge frame on the slag collection bin. When the pusher mechanism is closed, since a bottom plate is arranged at the bottom of the material receiving frame, at this time, the top of the slag collection hopper is disconnected from the incineration chamber, and the slag discharge frame can be pulled out of the slag collection bin by pulling the handle, and the slag can be discharged, realizing that the slag can be cleaned and discharged even when the incineration chamber is working, effectively improving the working efficiency.

[0030] The beneficial effects of the present invention are as follows:

[0031] (1) During the opening process of the pusher mechanism in the present invention, the pusher mechanism slides horizontally in the incineration chamber. The second rack can drive the transmission gear to rotate. The rotation of the transmission gear can drive the first transmission component to rotate. The rotation of the first transmission component can drive the second transmission component to rotate. And the rotation of the second transmission component can drive the sector gear to rotate. The sector gear rotates and intermittently cycles to engage with the first transmission rack and the second transmission rack, causing the transmission ring to slide horizontally left and right on the second track. The horizontal left and right sliding of the transmission ring on the second track can drive the aggregate hopper to slide horizontally left and right on the first track, thereby realizing the uniform spreading of domestic waste in the aggregate hopper into the pusher mechanism, avoiding the problem of garbage accumulation near the entrance during traditional manual feeding, making the domestic waste evenly heated, and effectively reducing the energy required for the pyrolysis of domestic waste;

[0032] (2) When the pusher mechanism slides horizontally in the incineration chamber in the present invention, the first rack drives the first gear to rotate. The first gear drives the vibration component to rotate. The rotation of the vibration component drives the dial wheel to rotate, thereby driving the movable material-bearing grille to slide vertically back and forth in the material-bearing frame, realizing the vibration of the movable material-bearing grille. Since the feeding mechanism sprinkles domestic waste into the pusher mechanism at this time, the vibration of the movable material-bearing grille can further help the domestic waste to be evenly distributed on the movable material-bearing grille, preventing the accumulation of domestic waste, making the domestic waste evenly heated during high-temperature pyrolysis, and reducing energy waste;

[0033] (3) When the pusher mechanism in the present invention is opened, the slag generated after the high-temperature pyrolysis of domestic waste can fall through the gaps on the fixed material-bearing grille, then enter the slag collection hopper, and finally enter the slag discharge frame on the slag collection bin. When the pusher mechanism is closed, since there is a bottom plate at the bottom of the material-bearing frame, at this time, the top of the slag collection hopper is disconnected from the incineration chamber. By pulling the handle, the slag discharge frame can be pulled out of the slag collection bin, and the slag can be discharged, realizing the cleaning and discharging of slag even when the incineration chamber is working, effectively improving the working efficiency.

DETAILED DESCRIPTION

[0049] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0050] like Figure 1 - Figure 2 As shown, an incinerator for pyrolysis and gasification incineration of domestic waste comprises an incineration chamber 1 and a pushing mechanism 2, the pushing mechanism 2 is slidably connected in the incineration chamber 1, a feeding mechanism 3 is slidably connected to the front side of the top of the incineration chamber 1, a transmission mechanism 4 is slidably connected to the top of the incineration chamber 1, a slag discharge mechanism 5 is fixedly arranged at the bottom of the incineration chamber 1, a secondary combustion chamber 6 is fixedly connected to the top of the incineration chamber 1, an exhaust gas treatment device 7 is fixedly connected to the top of the secondary combustion chamber 6, and a burner 8 is fixedly connected to the side of the incineration chamber 1;

[0051] The pushing mechanism 2 slides in the incineration chamber 1 to drive the transmission mechanism 4, and the transmission mechanism 4 can drive the feeding mechanism 3 to slide horizontally left and right on the top of the incineration chamber 1;

[0052] The bottom of the secondary combustion chamber 6 is communicated with the incineration chamber 1 , the top of the secondary combustion chamber 6 is communicated with the tail gas treatment device 7 , and the burner 8 is communicated with the incineration chamber 1 .

[0053] In this embodiment, when working, the pushing mechanism 2 is opened, and the operator puts domestic garbage into the feeding mechanism 3 from the top of the incineration chamber 1. During the opening and closing process of the pushing mechanism 2, the transmission mechanism 4 can be driven, and the transmission mechanism 4 drives the feeding mechanism 3 to slide horizontally left and right on the top of the incineration chamber 1, so that the domestic garbage in the feeding mechanism 3 is evenly scattered on the pushing mechanism 2, and then the pushing mechanism 2 is pushed into the incineration chamber 1, and the burner 8 is started to allow the domestic garbage entering the incineration chamber 1 to be pyrolyzed at high temperature. The domestic garbage evenly scattered into the pushing mechanism 2 avoids the problem of garbage accumulation near the entrance during traditional manual feeding, and effectively reduces the energy required for pyrolysis of domestic garbage. The combustible gas generated by pyrolysis enters the secondary combustion chamber 6, and the combustible gas is fully burned in the secondary combustion chamber 6 to remove most of the harmful substances. At the same time, a heat exchange device can be connected to the secondary combustion chamber 6 to fully utilize the heat generated by the full combustion of the combustible gas in the secondary combustion chamber 6. Subsequently, the flue gas generated by the combustion in the secondary combustion chamber 6 is passed into the exhaust gas treatment device 7, and the flue gas treated by the exhaust gas treatment device 7 can be discharged into the atmosphere in a standard manner.

[0054] like Figure 2 - Figure 7 As shown, electric push rods 11 are symmetrically fixedly connected to both sides of the incineration chamber 1, and the top of the electric push rods 11 is fixedly connected to the pushing mechanism 2;

[0055] The material pushing mechanism 2 includes a material receiving frame 21, a movable material receiving grid 22 and a vibration component 23. The top of the electric push rod 11 is fixedly connected to the material receiving frame 21, the movable material receiving grid 22 is vertically slidably connected in the material receiving frame 21, and there are multiple vibration components 23, which are symmetrically rotated and connected to both sides of the material receiving frame 21;

[0056] A fixed material receiving grid 12 is fixedly connected to the bottom of the incineration chamber 1, and a movable material receiving grid 22 can be inserted into the fixed material receiving grid 12;

[0057] The vibration component 23 includes a toggle wheel 231 and a first gear 232. The toggle wheel 231 is arranged below the movable material receiving grid 22. Avoidance grooves 13 are arranged on both sides of the fixed material receiving grid 12. The avoidance grooves 13 allow the first gear 232 to pass through. A first rack 131 is arranged at the bottom of the avoidance groove 13, and the first gear 232 is meshed with the first rack 131.

[0058] In this embodiment, the electric push rod 11 can drive the pushing mechanism 2 to slide horizontally in the incineration chamber 1, so that the pushing mechanism 2 can be automatically opened and closed, effectively reducing the difficulty of operation for the operator;

[0059] After the pusher mechanism 2 enters the incineration chamber 1, the movable material-bearing grille 22 and the fixed material-bearing grille 12 can form an integral material-bearing chassis, so that domestic waste can be pyrolyzed at high temperature on it. After the pusher mechanism 2 is pulled out of the incineration chamber 1, the slag generated after the high-temperature pyrolysis of domestic waste can fall through the gaps on the fixed material-bearing grille 12, quickly and conveniently discharging the slag, making room for the domestic waste to enter the incineration chamber 1 again, and simplifying the operation difficulty of the operator;

[0060] When the pusher mechanism 2 slides horizontally in the incineration chamber 1, the first rack 131 drives the first gear 232 to rotate, the first gear 232 drives the vibration member 23 to rotate, and the rotation of the vibration member 23 drives the dial wheel 231 to rotate, thereby driving the movable material-bearing grille 22 to slide vertically back and forth in the material-bearing frame 21, realizing the vibration of the movable material-bearing grille 22;

[0061] When the pusher mechanism 2 is pulled out of the incineration chamber 1, the vibration of the movable material-bearing grille 22 can drive the vibration of the slag generated by the high-temperature pyrolysis in the incineration chamber 1, thereby accelerating the fall of the slag from the gaps on the fixed material-bearing grille 12 and accelerating the discharge of the slag;

[0062] At the same time, when the feeding mechanism 3 sprinkles new domestic waste onto the pusher mechanism 2, the vibration of the movable material-bearing grille 22 can further help the domestic waste to be evenly distributed on the movable material-bearing grille 22, prevent the accumulation of domestic waste, make the domestic waste evenly heated during high-temperature pyrolysis, and reduce energy waste.

[0063] Such as Figure 8 - Figure 9 As shown, the feeding mechanism 3 includes a collecting hopper 31, a first feeding roller 32, a second feeding roller 33, a driving motor 34 and a transmission ring 35. A first track 14 is fixedly arranged on the front side of the top of the incineration chamber 1. The collecting hopper 31 is slidably connected to the first track 14. The first feeding roller 32 and the second feeding roller 33 are symmetrically rotatably connected in the collecting hopper 31. The driving motor 34 is fixedly connected to one side of the collecting hopper 31. The transmission ring 35 is fixedly connected to the rear side of the collecting hopper 31. A second track 15 is arranged on the top of the incineration chamber 1. The transmission ring 35 is slidably connected to the second track 15. A sealing plate 25 is fixedly connected to the top of the pusher mechanism 2, and the sealing plate 25 can seal the bottom of the collecting hopper 31;

[0064] A plurality of cutters are arranged alternately on the first feeding roller 32 and the second feeding roller 33. A driven gear 321 is fixedly connected to one side of the first feeding roller 32. A driving gear 331 is fixedly connected to one side of the second feeding roller 33. The driven gear 321 meshes with the driving gear 331, and the driving motor 34 can drive the second feeding roller 33 to rotate.

[0065] In this embodiment, the setting of the plugging plate 25 enables the plugging plate 25 to plug the bottom of the aggregate hopper 31 when the material pushing mechanism 2 is closed, preventing the leakage of domestic waste in the aggregate hopper 31. When the material pushing mechanism 2 is opened, the plugging plate 25 leaves the bottom of the aggregate hopper 31, and the domestic waste in the aggregate hopper 31 can fall into the material pushing mechanism 2;

[0066] When the driving motor 34 drives the second feeding roller 33 to rotate, the driving gear 331 rotates. The rotation of the driving gear 331 can drive the driven gear 321 to rotate, and the rotation of the driven gear 321 can drive the first feeding roller 32 to rotate. The first feeding roller 32 and the second feeding roller 33 can rotate towards each other, so that the domestic waste put into the aggregate hopper 31 can be sent below the aggregate hopper 31 by the first feeding roller 32 and the second feeding roller 33. The staggered cutting tools can crush the domestic waste put into the aggregate hopper 31 while sending it below the aggregate hopper 31, reducing the volume of the domestic waste entering the incineration chamber 1 and saving the energy required for the high-temperature pyrolysis of domestic waste.

[0067] As Figure 9 - Figure 12 As shown in the figure, the transmission mechanism 4 includes a first transmission component 41, a second transmission component 42 and a transmission chain 43. Both the first transmission component 41 and the second transmission component 42 are rotatably connected to the top of the incineration chamber 1. The second transmission component 42 is arranged inside the transmission ring 35. A first transmission wheel 411 is arranged on the first transmission component 41, a second transmission wheel 421 is arranged on the second transmission component 42, and the first transmission wheel 411 and the second transmission wheel 421 are connected by the transmission chain 43;

[0068] A second rack 24 is fixedly connected to the top of the material pushing mechanism 2. A transmission gear 412 is arranged on the first transmission component 41, and the transmission gear 412 meshes with the second rack 24. A first transmission rack 351 is arranged on the front side inside the transmission ring 35, a second transmission rack 352 is arranged on the rear side inside the transmission ring 35, and a sector gear 422 is arranged on the second transmission component 42. The sector gear 422 can mesh with the first transmission rack 351 or the second transmission rack 352.

[0069] In this embodiment, the rotation of the first transmission wheel 411 can drive the rotation of the second transmission wheel 421, that is, the rotation of the first transmission component 41 can drive the rotation of the second transmission component 42;

[0070] When the material pushing mechanism 2 slides horizontally in the incineration chamber 1, the second rack 24 can drive the transmission gear 412 to rotate, the rotation of the transmission gear 412 can drive the first transmission component 41 to rotate, and the rotation of the first transmission component 41 can drive the second transmission component 42 to rotate;

[0071] When the second transmission member 42 rotates, it can drive the sector gear 422 to rotate. The rotation of the sector gear 422 can intermittently and cyclically engage with the first transmission rack 351 and the second transmission rack 352, causing the transmission ring 35 to slide horizontally back and forth on the second track 15. The horizontal left - right sliding of the transmission ring 35 on the second track 15 can drive the aggregate hopper 31 to slide horizontally left and right on the first track 14, thereby realizing the uniform spreading of the domestic waste in the aggregate hopper 31 into the pushing mechanism 2.

[0072] As Figure 13 - Figure 14 shown, the slag discharging mechanism 5 includes a slag collecting hopper 51 and a slag discharging frame 52. The top of the slag collecting hopper 51 is connected to the incineration chamber 1. A slag collecting bin 511 is provided at the bottom of the slag collecting hopper 51. The slag discharging frame 52 is slidably connected in the slag collecting bin 511, and a handle 521 is fixedly connected to one side of the slag discharging frame 52.

[0073] In this embodiment, when the pushing mechanism 2 is opened, the slag falling from the incineration chamber 1 can enter the slag collecting hopper 51 and finally enter the slag discharging frame 52 on the slag collecting bin 511. When the pushing mechanism 2 is closed, since a bottom plate is provided at the bottom of the material - bearing frame 21, at this time, the top of the slag collecting hopper 51 is disconnected from the incineration chamber 1. By pulling the handle 521, the slag discharging frame 52 can be pulled out of the slag collecting bin 511, and the slag can be discharged, realizing the cleaning and discharging of the slag even when the incineration chamber 1 is working, effectively improving the working efficiency.

[0074] Working principle:

[0075] During operation, the electric push rod 11 is used to open the pushing mechanism 2. The operator throws domestic waste into the feeding mechanism 3 from above the incineration chamber 1. When the driving motor 34 is started and the driving motor 34 drives the second feeding roller 33 to rotate, the driving gear 331 rotates. The rotation of the driving gear 331 can drive the driven gear 321 to rotate, and the rotation of the driven gear 321 can drive the first feeding roller 32 to rotate. Moreover, the first feeding roller 32 and the second feeding roller 33 can rotate towards each other, so that the domestic waste put into the aggregate hopper 31 can be sent below the aggregate hopper 31 by the first feeding roller 32 and the second feeding roller 33. The staggered cutting tools can cause the domestic waste put into the aggregate hopper 31 to be crushed while being sent below the aggregate hopper 31;

[0076] When the pushing mechanism 2 is opened, the blocking plate 25 leaves the bottom of the aggregate hopper 31, and the domestic waste in the aggregate hopper 31 can fall into the pushing mechanism 2;

[0077] During the opening process of the pushing mechanism 2, the pushing mechanism 2 slides horizontally in the incineration chamber 1. The second rack 24 can drive the transmission gear 412 to rotate, the rotation of the transmission gear 412 can drive the first transmission member 41 to rotate, and the rotation of the first transmission member 41 can drive the second transmission member 42 to rotate;

[0078] The rotation of the second transmission component 42 can drive the rotation of the sector gear 422. The rotation of the sector gear 422 can intermittently and cyclically engage with the first transmission rack 351 and the second transmission rack 352, causing the transmission ring 35 to slide horizontally back and forth on the second track 15. The horizontal left and right sliding of the transmission ring 35 on the second track 15 can drive the collection hopper 31 to slide horizontally left and right on the first track 14, thereby realizing the uniform spreading of the domestic waste in the collection hopper 31 into the pushing mechanism 2;

[0079] At this time, the first rack 131 drives the first gear 232 to rotate, the first gear 232 drives the vibration component 23 to rotate, and the rotation of the vibration component 23 drives the dial wheel 231 to rotate, thereby driving the movable material receiving grille 22 to slide vertically back and forth in the material receiving frame 21, realizing the vibration of the movable material receiving grille 22;

[0080] Since the feeding mechanism 3 spreads domestic waste into the pushing mechanism 2 at this time, the vibration of the movable material receiving grille 22 can further help the domestic waste to be evenly distributed on the movable material receiving grille 22, prevent the accumulation of domestic waste, make the domestic waste evenly heated during high-temperature pyrolysis, and reduce energy waste;

[0081] Then, the electric push rod 11 is used to close the pushing mechanism 2. During the closing process of the pushing mechanism 2, the pushing mechanism 2 slides horizontally in the incineration chamber 1, the collection hopper 31 continues to slide horizontally left and right on the first track 14, spreading the domestic waste in the collection hopper 31 evenly into the pushing mechanism 2, and the movable material receiving grille 22 continues to vibrate, continuing to help the domestic waste to be evenly distributed on the movable material receiving grille 22;

[0082] Until the pushing mechanism 2 is completely closed, the sealing plate 25 seals the bottom of the collection hopper 31, and the domestic waste in the collection hopper 31 stops falling. At this time, the driving motor 34 is turned off;

[0083] Then, the burner 8 is turned on to pyrolyze the domestic waste entering the incineration chamber 1 at high temperature. The combustible gas generated by pyrolysis enters the secondary combustion chamber 6, and the combustible gas burns fully in the secondary combustion chamber 6 to remove most of the harmful substances. At the same time, a heat exchange device can be connected to the secondary combustion chamber 6 to make full use of the heat generated by the full combustion of the combustible gas in the secondary combustion chamber 6. Subsequently, the flue gas generated by combustion in the secondary combustion chamber 6 is introduced into the tail gas treatment device 7, and the flue gas treated by the tail gas treatment device 7 can be discharged up to standard into the atmosphere.

[0084] After the pushing mechanism 2 is closed, the pushing mechanism 2 completely enters the incineration chamber 1, and the movable material receiving grille 22 and the fixed material receiving grille 12 can form an integral material receiving chassis for the domestic waste to pyrolyze at high temperature on it;

[0085] When the pusher mechanism 2 is opened, the slag generated after the high-temperature pyrolysis of domestic waste can fall through the gaps on the fixed material-loading grille 12, then enter the slag collection hopper 51, and finally enter the slag discharge frame 52 on the slag collection bin 511;

[0086] When the pusher mechanism 2 is pulled out of the incineration chamber 1, the vibration of the movable material-loading grille 22 can drive the vibration of the slag generated by the high-temperature pyrolysis in the incineration chamber 1, thereby accelerating the fall of the slag through the gaps on the fixed material-loading grille 12 and accelerating the discharge of the slag;

[0087] When the pusher mechanism 2 is closed, since a bottom plate is provided at the bottom of the material-loading frame 21, at this time, the top of the slag collection hopper 51 is disconnected from the incineration chamber 1. By pulling the handle 521, the slag discharge frame 52 can be pulled out of the slag collection bin 511, and the slag can be discharged, realizing that the slag can be cleaned and discharged even when the incineration chamber 1 is working, effectively improving the working efficiency.

[0088] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
