DETAILED DESCRIPTION

[0018] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0019] like Figure 1-10The incinerator for waste incineration power plant shown in the figure is easy to control, including a furnace body 10 and an incinerator spray gun 11. A smoke exhaust pipe 3 is installed on the top of the furnace body 10, and an incineration support plate 18 is installed inside the furnace body 10. A ball screw 12 is installed on the top of the furnace body 10, and the top of the ball screw 12 extends to the top of the furnace body 10. The bottom end of the ball screw 12 is movably connected with the incineration support plate 18. Long blocks 15 are provided on both sides of the ball screw 12. A wavy slide groove 16 is opened on the side of the long block 15. A garbage support plate 14 is provided between the two long blocks 15. A second slide groove 23 is opened on the surface of the garbage support plate 14. The ball screw 12 is inserted in the second slide groove 23. Two limit baffles 24 are fixedly sleeved on the surface of the nut of the ball screw 12. The surfaces of the two limit baffles 24 are in contact with the top and bottom of the garbage support plate 14 respectively. Both ends of the garbage support plate 14 are installed The slider 21, one end of the two sliders 21 extends to the inside of the two wavy chute 16 respectively, and the top of the ball screw 12 is connected to the driving motor 4. When the garbage on the garbage support plate 14 is dropped to the incineration area by vibration, it is only necessary to control the driving motor 4 to be powered on, and the active end of the ball screw 12 moves in the vertical direction after being forced, and at the same time drives the garbage support plate 12 to move synchronously. When the garbage support plate 14 moves, it drives the slider 21 to slide along the wavy chute 16, so that the garbage support plate 14 vibrates back and forth in the horizontal direction on the active end surface of the ball screw 12 through the second chute 23, so that the garbage is gradually dropped from the garbage support plate 14 due to vibration. By reducing the rate at which the garbage falls to the incineration area, the amount of garbage falling on the surface of the incinerated garbage is reduced, the range of contact between the flame and the surrounding air and the intensity of the flame are increased, and the efficiency of garbage incineration in the incinerator is improved.

[0020] A feeding port is provided at the top of the furnace body 10, and a ventilation port 1 is provided at the bottom of the furnace body 10. The ventilation port 1 and the feeding port are respectively located below and above the incineration support plate 18. A movable baffle 2 is movably installed in the feeding port. The feeding port can allow garbage to be fed to the top of the garbage support plate 14, and the ventilation port 1 can allow air to flow from the bottom of the furnace body 10 to the bottom of the incineration support plate 18, thereby facilitating air circulation into the furnace body 10.

[0021] The incinerator spray gun 11 is installed through the side of the furnace body 10. The incinerator spray gun 11 is located above the incineration support plate 18. The incinerator spray gun 11 also needs to be connected to the power switch through a wire and to the gas fuel bottle through a hose. The power switch also needs to; when spraying garbage, only the valve of the gas fuel bottle needs to be opened, and the gas fuel is transported to the muzzle of the incinerator spray gun 11 through the hose. At the same time, the incinerator spray gun 11 is energized, and electric sparks are generated at the muzzle of the incinerator spray gun 11. When the fuel contacts the electric sparks, an open flame is generated. The flame ignites the garbage along with the sprayed fuel. After a period of spraying, the flame on the surface of the garbage stabilizes, and the incinerator spray gun 11 is stopped.

[0022] A mounting shaft 19 is installed on the top of the incineration support plate 18 through a bearing, the top of the mounting shaft 19 is connected to the bottom end of the ball screw 12, a fixing ring 17 is arranged around the mounting shaft 19, the bottom of the fixing ring 17 contacts the top of the incineration support plate 18, a plurality of connecting rods 20 are installed between the mounting shaft 19 and the top of the fixing ring 17, a plurality of second pusher blocks 32 are installed on the arc surface of the mounting shaft 19, a plurality of first pusher blocks 30 are installed on the inner arc surface of the fixing ring 17, and a third pusher block 31 is installed at the bottom of each of the plurality of connecting rods 20. 31 is located between the second pusher block 32 and the first pusher block 30. During the rotation of the ball screw 12 under force, the mounting shaft 19 is driven to rotate synchronously on the surface of the incineration support plate 18. The mounting shaft 19 drives the fixing ring 17 to rotate on the top of the incineration support plate 18 through multiple connecting rods 20, and at the same time drives multiple third pusher blocks 31, the second pusher block 32 and the first pusher block 30 to rotate on the top of the incineration support plate 18, so as to push the garbage accumulated on the top of the incineration support plate 18, so that the garbage can be evenly dispersed, so that the garbage can fully contact with the flame, and the garbage can be fully burned.

[0023] A plurality of ash holes 33 are provided on the surface of the incineration support plate 18 . Ash produced after the garbage on the top of the incineration support plate 18 is burned can be dropped to the inner bottom surface of the furnace body 10 through the ash holes 33 . The staff can clean the ash out of the furnace body 10 through the vent 1 .

[0024] A garbage baffle 13 is provided above the garbage support plate 14, and a plurality of support adjustment mechanisms are provided between the garbage baffle 13 and the side of the garbage support plate 14. The garbage baffle 13 is used to limit the position of the garbage on the top of the garbage support plate 14, and the distance between the top of the garbage support plate 14 and the bottom of the garbage baffle 13 can allow the garbage to fall due to vibration. At the same time, as the height of the garbage baffle 13 increases, the height of the garbage that can be piled on the garbage support plate 14 increases accordingly.

[0025] The support adjustment mechanism includes a first fixing block 28 and a second fixing block 29, which are respectively mounted on the surface of the garbage support plate 14 and the garbage baffle 13. A screw 34 is mounted on the top of the first fixing block 28. The top of the screw 34 passes through the surface of the second fixing block 29 and extends above it. Two mounting screw tubes 35 are threadedly sleeved on the surface of the screw 34. The ends of the two mounting screw tubes 35 are respectively in contact with the top and bottom of the second fixing block 29. When the height of the garbage baffle 13 is adjusted, the top of the garbage support plate 14 and the garbage baffle 13 can be adjusted. The spacing distance between the bottom of the plate 13, during operation, only needs to rotate the two mounting screws 35 at the same time, and the two mounting screws 35 will rise or fall on the screw 34 according to the different rotation directions, so that the two mounting screws 35 can drive the second fixed block 29 to rise or fall, and the spacing distance between the top of the garbage support plate 14 and the bottom of the garbage baffle 13 can be adjusted conveniently. When the spacing distance is large, more garbage will fall into the incineration area, and when the spacing distance is small, less garbage will fall into the incineration area. Adaptive adjustment can be performed according to work requirements.

[0026] Two fixed slide bars 25 are installed at the movable end of the ball screw 12, and two symmetrical sides of the second slide groove 23 are provided with slide holes 27. One end of the two fixed slide bars 25 is respectively inserted into the two slide holes 27, and the surfaces of the two fixed slide bars 25 are movably sleeved with shock-absorbing springs 26. The two ends of the shock-absorbing springs 26 are respectively connected to the movable end of the ball screw 12 and the inner side of the second slide groove 23. The garbage support plate 14 slides on the two fixed slide bars 25 in the horizontal direction, and the garbage support plate 14 squeezes and stretches the two shock-absorbing springs 26 respectively. After the shock-absorbing springs 26 are subjected to force, the force strength of the garbage support plate 14 can be reduced to prevent damage caused by a hard collision between the garbage support plate 14 and the ball screw 12, thereby protecting the garbage support plate 14.

[0027] A fixing rod 5 is installed through the top of the furnace body 10, and a first slide groove 22 is provided on the surface of the garbage supporting plate 14. The bottom end of the fixing rod 5 passes through the first slide groove 22 and extends below it. Two limit blocks 36 are installed at the bottom end of the fixing rod 5. The surfaces of the two limit blocks 36 are respectively in contact with the top and bottom of the garbage supporting plate 14. The top of the fixing rod 5 extends to the top of the furnace body 10. A supporting block 6 is installed at the top of the fixing rod 5. A fixing plate 9 is provided on one side of the fixing rod 5. A long hole 8 is provided on the side of the fixing plate 9. One end of the supporting block 6 extends into the long hole 8. Travel switches 7 are installed on the top and bottom of the supporting block 6. The two travel switches 7 correspond to the internal top and bottom positions of the long hole 8 respectively. The two travel switches 7 are connected to the driving motor 4 through wires. When the garbage supporting plate 14 cannot complete the garbage falling during a single lifting process, the garbage can be controlled. The garbage support plate 14 is lifted and lowered reciprocatingly for multiple times. During the operation, as the garbage support plate 14 moves downward, the garbage support plate 14 drives the fixed rod 5 to move synchronously, and the fixed rod 5 drives the two travel switches 7 to slide in the long hole 8. When the travel switch 7 located at the bottom contacts the inner bottom surface of the long hole 8, the garbage support plate 14 reaches the end of the moving stroke. At this time, the travel switch 7 controls the active end of the drive motor 4 to rotate in the opposite direction, which is convenient for controlling the garbage support plate 14 to move in the opposite direction. When the travel switch 7 located at the top contacts the inner top surface of the long hole 8, the travel switch 7 controls the active end of the drive motor 4 to rotate in the opposite direction, which is convenient for controlling the garbage support plate 14 to move back and forth for multiple times. During the reciprocating motion, the slider 21 is also pressed in the wavy slide groove 16 to vibrate in the horizontal direction, which is convenient for putting the garbage accumulated on the top of the garbage support plate 14 into the incineration area.
