[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A garbage incineration power generation device includes an incinerator 1, a garbage feed pipe 2 is fixedly connected to the side wall of the incinerator 1, and a manual butterfly valve is provided on the garbage feed pipe 2, which is not shown in the figure. Closing the garbage feed pipe 2 is a prior art. A tilted combustion plate 3 is fixedly connected to the lower part of the inner wall of the incinerator 1, and garbage can be incinerated on the combustion plate 3. Its incineration ignition method is a prior art. A slag discharge pipe 4 is fixedly connected to the inner wall of the incinerator 1 located at the lower left side of the combustion plate 3, and a smoke exhaust pipe 5 is fixedly connected to the top of the incinerator 1. The hot flue gas in the incinerator 1 can be discharged to the external hot boiler for heat exchange to generate superheated steam, which drives the steam turbine generator set to generate electricity.

[0023] A plurality of pump air pipes 6 are fixedly connected to the side wall of the combustion plate 3, and a one-way valve is installed on the inner wall of the pump air pipe 6. The one-way valve only allows outside air to enter the incinerator 1, so that the outside air enters the incinerator 1 to provide oxygen to the garbage incineration environment and increase the garbage incineration effect.

[0024] The incinerator 1 is provided with a stirring mechanism for stirring the garbage on the combustion plate 3. The stirring mechanism includes two rotating shafts 7 which are sealed and rotatably connected to the inner wall of the incinerator 1. The side walls of the rotating shafts 7 are fixedly connected with fixed cylinders 8. The side walls of the fixed cylinders 8 are fixedly connected with multiple scraping teeth 9. The two rotating shafts 7 are located on the combustion plate 3. One end of the two rotating shafts 7 passes through the inner wall of the incinerator 1 and are respectively fixedly connected with two first wheels 10. A synchronous belt is connected between the two first wheels 10. The side wall of the incinerator 1 is fixedly connected with a first motor 11 through a bracket. The movable end of the first motor 11 is fixedly connected to one end of one of the rotating shafts 7.

[0025] Furthermore, when the garbage is incinerated on the combustion plate 3, the first motor 11 is driven to rotate counterclockwise, and then the two rotating shafts 7 rotate synchronously under the action of the two first wheels 10 and the synchronous belt, so that the two fixed cylinders 8 drive the multiple scrapers 9 to rotate, which can stir the garbage obliquely upward to avoid the garbage from piling up, so that the contact area between the internal garbage and the air is small, a large amount of harmful smoke will be generated during the incineration process, and there will be unclean garbage in the slag discharged from the incinerator later, which affects the subsequent centralized treatment of the slag.

[0026] The upper end of the inner wall of the incinerator 1 is slidably connected to an annular frame 12, and the upper end of the annular frame 12 is elastically connected to the top of the incinerator 1 through multiple springs 13. The inner wall of the annular frame 12 is fixedly connected to a filter plate 14, which can block the floating ash in the incinerator 1 and perform preliminary treatment on the exhaust flue gas. The inner wall of the incinerator 1 located below the annular frame 12 is sealed and rotatably connected to a cross bar 15, and the side wall of the cross bar 15 is fixedly connected to two cams 17, and the side wall of the cam 17 is in contact with the lower end of the annular frame 12. A second motor 16 is fixedly connected to the side wall, and a movable end of the second motor 16 is fixedly connected to one end of the cross bar 15, so that when the second motor 16 rotates, the cross bar 15 drives the two cams 17 to rotate continuously, and then the annular frame 12 slides up and down under the squeezing of the two cams 17 and the elastic force of multiple springs 13, and the ash accumulated on the lower surface of the filter plate 14 can be shaken off to prevent the ash from accumulating on the lower surface of the filter plate 14 and affecting the normal discharge of smoke in the incinerator 1.

[0027] An L-shaped baffle 18 is sealingly and slidingly connected to the inner wall of the slag discharge pipe 4, and a plurality of electric push rods 19 are fixedly connected to the upper end of the slag discharge pipe 4. The movable end of the electric push rod 19 is fixedly connected to the lower end of the L-shaped baffle 18. During the garbage incineration process, the lower surface of the L-shaped baffle 18 fits tightly with the bottom of the slag discharge pipe 4 to prevent the discharge of garbage and smoke. When the slag needs to be discharged later, the plurality of electric push rods 19 can be adjusted to extend so that the L-shaped baffle 18 moves up, and the slag can flow out of the slag discharge pipe 4.

[0028] In the utility model, when the garbage is incinerated to generate electricity, the manual butterfly valve on the garbage feed pipe 2 is opened, and the garbage can be transported to the combustion plate 3 through the garbage feed pipe 2, and then the garbage on the combustion plate 3 can be incinerated by an external igniter, and after the garbage is transported, the manual butterfly valve is closed;

[0029] During the garbage incineration process, the incinerator 1 is pumped with air through a plurality of pump air pipes 6, so that the outside air enters the incinerator 1, providing oxygen to the garbage incineration environment and increasing the incineration effect of the garbage;

[0030] And drive the first motor 11 to rotate counterclockwise, at this time, the two rotating shafts 7 rotate synchronously under the action of the two first wheels 10 and the synchronous belt, so that the two fixed cylinders 8 drive the multiple scraping teeth 9 to rotate, which can stir the garbage obliquely upward to prevent the garbage from piling up and affecting its incineration effect;

[0031] During the incineration process of garbage, the flue gas and ash generated will flow upward. At this time, the filter plate 14 can initially block the ash. Then the flue gas will be discharged through the exhaust pipe 5 to the external hot boiler for heat exchange, generating superheated steam to drive the steam turbine generator set to generate electricity;

[0032] At the same time, the second motor 16 is driven to rotate, and then the cross bar 15 drives the two cams 17 to rotate continuously, and then the annular frame 12 slides up and down under the extrusion of the two cams 17 and the elastic force of the multiple springs 13, and the ash accumulated on the lower surface of the filter plate 14 can be shaken off to prevent the ash from accumulating on the lower surface of the filter plate 14 and affecting the normal discharge of the smoke in the incinerator 1;

[0033] When the slag in the incinerator 1 needs to be discharged after the garbage is incinerated, the multiple electric push rods 19 are adjusted to extend so that the L-shaped baffle 18 moves up, and the first motor 11 is driven to rotate clockwise, and then the multiple scrapers 9 rotate clockwise, which can speed up the flow of slag out of the slag discharge pipe 4.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
