Currently, the commonly used method for treating municipal solid waste incineration fly ash is to incinerate the fly ash of domestic waste through a melting treatment device. Generally, the fly ash to be treated is put into the device, and then the air in the device is heated to about 1300 °C, and the stirring component stirs the fly ash located in the device to ensure that the fly ash will come into full contact with the high-temperature air and will not fail to melt sufficiently due to accumulation.

[0003] The existing stirring components generally stir in one direction, and the stirring direction is too single, resulting in only partial stirring of the fly ash and unable to improve the overall melting efficiency of the fly ash. Summary of the Invention

Therefore, a device for melting municipal solid waste incineration fly ash is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A barrel body, the lower surface of the barrel body is provided with a plurality of support legs, a heating device is arranged inside the side wall of the barrel body, and a feed inlet and a discharge outlet are respectively opened on the upper surface and the lower surface of the barrel body;

[0008] A smoke outlet component for discharging the accumulated gas in the barrel body;

[0009] A first stirring component for horizontally stirring the municipal solid waste incineration fly ash located in the barrel body. The first stirring component includes a servo motor fixedly installed on the upper surface of the barrel body, a rotating shaft, and a plurality of stirring rods rotatably installed on the side wall of the rotating shaft. The output shaft of the servo motor penetrates into the barrel body and is fixedly connected to one end of the rotating shaft;

[0010] A disturbance component for vertically stirring the municipal solid waste incineration fly ash located in the barrel body. The disturbance component includes a plurality of rotating rods respectively fixedly installed at the ends of the plurality of stirring rods far from the rotating shaft and a plurality of disturbance rods respectively fixedly installed on the plurality of rotating rods;

[0011] A driving component, which is used to provide driving force for multiple rotating rods to rotate vertically together.

[0012] Preferably, the driving component includes multiple gears respectively fixedly installed at one end of multiple rotating rods away from the stirring rod and a rack ring fixedly installed in the barrel body. The multiple gears are meshed and connected, and the gears located at the uppermost part are all meshed and connected with the rack ring.

[0013] Preferably, a second stirring component is provided on the stirring rod, and the second stirring component is used to stir the fly ash in the barrel body horizontally.

[0014] Preferably, the second stirring component includes a stirring plate. A reciprocating thread is provided on the surface of the stirring rod, the stirring plate is threadedly sleeved on the stirring rod, and the stirring plate is restricted from rotating by a limiting component.

[0015] Preferably, the limiting component includes a limiting rod horizontally and fixedly installed on the side wall of the rotating shaft, and the stirring plate is slidably sleeved on the limiting rod.

[0016] Preferably, the smoke outlet component includes an L-shaped smoke outlet pipe communicated with the inside of the barrel body and a filter screen arranged at the smoke outlet of the smoke outlet pipe. The filter screen is fixedly installed at the smoke outlet of the smoke outlet pipe through a clamping component, and an electric control valve is provided at the smoke inlet of the smoke outlet pipe.

[0017] Preferably, the clamping component includes placement plates fixedly installed on the front and rear surfaces of the filter screen and two clamping openings respectively vertically opened on the surfaces of the two placement plates. Placement platforms are fixedly installed on the front and rear surfaces at the smoke outlet of the smoke outlet pipe, and clamping rods are fixedly installed on the upper surfaces of the two placement platforms. The position of the filter screen on the clamping rods is restricted by a limiting component.

[0018] Preferably, the limiting component includes a mounting plate fixedly installed on the side wall of the smoke outlet pipe and a spring rod vertically and rotatably installed on the upper surface of the mounting plate.

The filter screen is no longer fixed to the smoke outlet of the smoke outlet pipe through screw and nut fixing parts.

[0024] 4. When the high-temperature flue gas flows in the smoke outlet pipe, the rotating blades located in the smoke outlet pipe will rotate at high speed. During the rotation process, some of the larger-volume fly ash in the high-temperature flue gas will be crushed, reducing the frequency of the filter screen being blocked by the larger-volume fly ash, thereby reducing the working frequency of the staff to clean the filter screen.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] Referring to Figures 1-5 , a garbage incineration fly ash melting treatment device includes:

[0033] A barrel body 1, with multiple support legs 2 provided on the lower surface of the barrel body 1, a heating device provided inside the side wall of the barrel body 1, and a feed inlet 3 and a discharge outlet 4 respectively opened on the upper surface and the lower surface of the barrel body 1;

[0034] A smoke outlet assembly for discharging the accumulated gas inside the barrel body 1;

[0035] A first stirring assembly for stirring the garbage fly ash located inside the barrel body 1 in the horizontal direction. The first stirring assembly includes a servo motor 5 fixedly installed on the upper surface of the barrel body 1, a rotating shaft 6, and multiple stirring rods 7 rotatably installed on the side wall of the rotating shaft 6. The output shaft of the servo motor 5 penetrates into the barrel body 1 and is fixedly connected to one end of the rotating shaft 6;

[0036] A disturbance assembly for stirring the garbage fly ash located inside the barrel body 1 in the vertical direction. The disturbance assembly includes multiple rotating rods 8 respectively fixedly installed at the ends of the multiple stirring rods 7 away from the rotating shaft 6 and multiple disturbance rods 9 respectively fixedly installed on the multiple rotating rods 8;

[0037] A driving component for providing a driving force for the multiple rotating rods 8 to rotate together in the vertical direction.

[0038] In the embodiments applying the above technical solutions, through the cooperation among the first stirring assembly, the disturbance assembly and the driving component, when the servo motor 5 is started, the output shaft of the servo motor 5 drives the rotating shaft 6, the multiple stirring rods 7 and the multiple rotating rods 8 to stir the fly ash located inside the barrel body 1 in the horizontal direction. At the same time, the multiple rotating rods 8 will also drive the disturbance rods 9 fixedly installed on themselves to stir the fly ash in the vertical direction. The stirring directions are diverse, so that the fly ash at any position can be stirred, and the flow rate of the high-temperature air inside the barrel body 1 can be increased, and the overall melting efficiency of the fly ash can be improved.

[0039] In the preferred technical solution of this embodiment, the driving component includes a plurality of gears 10 respectively fixedly installed at one end of multiple rotating rods 8 away from the stirring rod 7 and a rack ring 11 fixedly installed in the barrel 1. The multiple gears 10 are meshed and connected, and the gears 10 located at the uppermost part are all meshed and connected with the rack ring 11. When the servo motor 5 is started, the output shaft of the servo motor 5 will drive the rotating shaft 6, multiple stirring rods 7 and multiple rotating rods 8 to rotate horizontally together. During the rotation, since the two gears 10 respectively fixedly sleeved at one end of the two rotating rods 8 located at the uppermost part are both meshed and connected with the rack ring 11, at this time, these two gears 10 will drive these two rotating rods 8 to rotate vertically. Also, because the multiple gears 10 are meshed and connected, when the two gears 10 located at the uppermost part rotate, at this time, the remaining multiple gears 10 will also rotate, so that the multiple rotating rods 8 will rotate together, and the rotation directions of two adjacent rotating rods 8 in the vertical direction are opposite, thus achieving a better flow disturbance effect, accelerating the flow rate of the high-temperature air in the barrel 1, and improving the overall melting efficiency of the fly ash.

[0040] In the preferred technical solution of this embodiment, the stirring rod 7 is provided with a second stirring assembly for horizontally stirring the waste fly ash located in the barrel 1.

[0041] In the preferred technical solution of this embodiment, the second stirring assembly includes a stirring plate 12. The surface of the stirring rod 7 is provided with a reciprocating thread, and the stirring plate 12 is threadedly sleeved on the stirring rod 7. The stirring plate 12 is restricted from rotating by a limiting component. When the gear 10 drives the rotating rod 8 to rotate, at this time, the stirring rod 7 will also rotate, so that the stirring plate 12 threadedly sleeved on the stirring rod 7 will move horizontally under the action of the limiting component at this time. During the movement, it will stir the fly ash in the barrel 1, accelerating the stirring rate of the fly ash and improving the overall melting efficiency of the fly ash.

[0042] In the preferred technical solution of this embodiment, the limiting component includes a limiting rod 13 horizontally fixedly installed on the side wall of the rotating shaft 6, and the stirring plate 12 is slidably sleeved on the limiting rod 13. The stirring plate 12 can only move horizontally on the limiting rod 13. Thus, when the stirring rod 7 rotates, at this time, the stirring plate 12 threadedly sleeved on the stirring rod 7 can only move horizontally and will not rotate together with the rotation of the stirring rod 7.

[0043] In the preferred technical solution of this embodiment, the smoke outlet assembly includes an L-shaped smoke outlet pipe 14 connected to the inside of the barrel body 1 and a filter screen 15 provided at the smoke outlet of the smoke outlet pipe 14. The filter screen 15 is fixedly installed at the smoke outlet of the smoke outlet pipe 14 through a clamping member, and an electric control valve is provided at the smoke inlet of the smoke outlet pipe 14. The filter screen 15 can filter some relatively large fly ash that has not been completely melted, and the electric control valve can prevent some fly ash from entering the smoke outlet pipe 14 during the melting process of the fly ash located in the barrel body 1, resulting in the inability to be melted.

[0044] In the preferred technical solution of this embodiment, the clamping member includes placement plates 16 fixedly installed on the front and rear surfaces of the filter screen 15 and two clamping ports 17 respectively vertically opened on the surfaces of the two placement plates 16. Placement platforms 18 are fixedly installed on the front and rear surfaces at the smoke outlet of the smoke outlet pipe 14, and clamping rods 19 are fixedly installed on the upper surfaces of the two placement platforms 18. The position of the filter screen 15 on the clamping rods 19 is restricted by a restricting member. When the staff installs the filter screen 15, they only need to align the two clamping ports 17 with the two clamping rods 19 and move them downwards, so that the two clamping rods 19 respectively enter the two clamping ports 17, and then fix the position of the filter screen 15 on the clamping rods 19 through the restricting member. Through the cooperation between the restricting member and the clamping member, the filter screen 15 can be quickly removed from the smoke outlet of the smoke outlet pipe 14 and cleaned, which is convenient and fast. The filter screen 15 is no longer fixedly installed at the smoke outlet of the smoke outlet pipe 14 through screw and nut fixing parts.

[0045] In the preferred technical solution of this embodiment, the restricting member includes a mounting plate 20 fixedly installed on the side wall of the smoke outlet pipe 14 and a spring rod 22 vertically rotatably installed on the upper surface of the mounting plate 20. The lower surface of the filter screen 15 is fixedly connected to the top end of the spring rod 22 through a connecting plate. As long as the spring rod 22 is first pulled to control its stretching, so that the two clamping rods 19 are respectively removed from the two clamping ports 17, at this time the clamping between the clamping rods 19 and the clamping ports 17 is released, and then the spring rod 22 is rotated to remove the filter screen 15 from the smoke outlet of the smoke outlet pipe 14. At this time, the upper and lower surfaces of the filter screen 15 can be cleaned. After cleaning, the spring rod 22 is pulled again to stretch it, and then the spring rod 22 is rotated to align the two clamping ports 17 with the two clamping rods 19, and then the spring rod 22 is released. The spring rod 22 will quickly drive the filter screen 15 to move downwards, and the two clamping rods 19 will instantly insert into the two clamping ports 17 to form a clamp. And under the elastic potential energy of the spring rod 22, the filter screen 15 will not move in the vertical direction.

[0046] In the preferred technical solution of this embodiment, a rotary blade 21 is rotatably installed in the smoke outlet pipe 14 through two connecting rods 23. When it is necessary to collect the toxic flue gas accumulated in the barrel 1, first open the electric control valve, and then suck at the smoke outlet of the smoke outlet pipe 14 through a suction fan. At this time, the toxic flue gas in the barrel 1 will flow at a high speed in the smoke outlet pipe 14. At this time, the rotary blade 21 in the smoke outlet pipe 14 will rotate at a high speed. During the rotation, some of the larger fly ash that has not been completely melted in the high-temperature flue gas will be crushed, reducing the frequency of the filter screen 15 being blocked by the larger fly ash, thereby reducing the working frequency of the staff to clean the filter screen 15.

[0047] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
