[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] The following gives specific embodiments.

[0026] Please refer to Figures 1 - 5, the utility model provides a garbage conveying device for an incinerator, which includes an outer cylinder 1. Fixed frames 2 are fixed at both ends of the outer cylinder 1. An inlet 3 is fixed at one end of the outer cylinder 1. A screw conveyor 10 is fixed inside the outer cylinder 1. The inlet 3 is communicated with the screw conveyor 10. A discharge box 5 is fixed at the other end of the outer cylinder 1. A crushing component is arranged on the inner side of the end of the discharge box 5 close to the outer cylinder 1. An adsorption component is arranged at the lower end inside the discharge box 5. A heating pipe 11 is sleeved at a position inside the outer cylinder 1 and outside the screw conveyor 10. An inlet port 8 is fixed at one end of the heating pipe 11. An exhaust port 9 is fixed at the other end of the heating pipe 11. A cover 4 is fixed at the end of the outer cylinder 1 away from the inlet 3. When working, before the conveying operation, first connect the inlet port 8 with the exhaust pipe of the incinerator, so that part of the high-temperature flue gas during combustion can enter the inside of the heating pipe 11 through the inlet port 8, and then heat the inside of the screw conveyor 10 through the heating pipe 11, and finally discharge it out through the exhaust port 9. Then, the garbage enters the inside of the screw conveyor 10 through the inlet 3 and is conveyed towards the discharge box 5 through the screw conveyor 10 and discharged out through the discharge box 5. When the garbage enters the inside of the screw conveyor 10, the high heat inside it will evaporate and dry the moisture in the garbage, thereby reducing the moisture in the garbage. Subsequently, the garbage is crushed by the crushing component, and then the iron filings and metals contained in the garbage are adsorbed and collected by the adsorption component. This step can effectively utilize the excess heat during the combustion of the combustion furnace through the combined structural design of the inlet port 8, the exhaust port 9 and the heating pipe 11, so that the moisture in the garbage is evaporated and dried, thereby reducing the moisture in the garbage, facilitating the improvement of the combustion efficiency of the garbage, reducing the combustion cost, and at the same time, the dried garbage can be crushed by the crushing component, further improving the combustion effect of the garbage and enhancing the practicability of the device.

[0027] Furthermore, as Figure 2 and Figure 3As shown in the figure, the crushing component includes a fixed box 7; the fixed box 7 is fixed at one side of the discharge box 5; a motor 12 is fixed inside the fixed box 7; two crushing rollers 15 are symmetrically arranged inside the discharge box 5; both crushing rollers 15 are rotatably connected to the discharge box 5; one end of the crushing roller 15 extends inside the fixed box 7; one ends of the two crushing rollers 15 located inside the fixed box 7 are respectively fixed with a driving gear 13 and a transmission gear 14; the driving gear 13 is meshed with the transmission gear 14; the output end of the motor 12 is fixedly connected to the driving gear 13. During operation, when the garbage falls between the two crushing rollers 15 through the screw conveyor 10 and the outer cylinder 1, by starting the motor 12, the motor 12 drives the driving gear 13 to rotate. When the driving gear 13 rotates, it drives the other crushing roller 15 to rotate simultaneously through the transmission gear 14, so that the two crushing rollers 15 rotate simultaneously, and then the garbage located between the two crushing rollers 15 is crushed. This step can effectively crush the garbage through the structural design of the two crushing rollers 15, thereby improving the combustion efficiency of the garbage and reducing the combustion cost.

[0028] Further, as Figure 2 and Figure 3 shown, a baffle 16 is fixed at the position inside the discharge box 5 and below the crushing roller 15. During operation, when the garbage is crushed by the two crushing rollers 15 and then falls to the top of the baffle 16, and then is discharged downward through the baffle 16. This step can guide the crushed garbage through the baffle 16 to avoid the garbage falling vertically.

[0029] As Figure 4 shown, the adsorption component includes two magnetic adsorption plates 17; the two magnetic adsorption plates 17 are respectively arranged inside the discharge box 5 and at the position below the baffle 16; there is a height difference between the two magnetic adsorption plates 17; one side of the magnetic adsorption plate 17 is fixed with a connecting slider 18; the connecting slider 18 is slidably connected to the discharge box 5; a plug-in slot 21 is opened at one end of the connecting slider 18 away from the discharge box 5; a plug-in component is arranged at the position inside the discharge box 5 corresponding to the plug-in slot 21. During operation, the garbage that has fallen through the baffle 16 will fall to the top of the magnetic adsorption plate 17 and flow downward through the magnetic adsorption plate 17. When the garbage passes through the magnetic adsorption plate 17, the iron filings in the crushed garbage will be adsorbed by the magnetism of the magnetic adsorption plate 17 itself. This step can effectively adsorb the iron filings and metals in the crushed garbage through the structural design of the magnetic adsorption plate 17, so as to collect the iron filings and metals in the garbage centrally, avoid waste of resources, and at the same time, through the structural design of the plug-in component, it can effectively prevent the magnetic adsorption plate 17 from sliding out of the inside of the discharge box 5, improving the practicability of the device.

[0030] As Figure 5As shown, the plug-in assembly includes a plug-in block 22; the plug-in block 22 is arranged on the inner side of the discharge box 5 and at a position corresponding to the plug-in slot 21; the plug-in block 22 is slidably connected to the discharge box 5; a connecting rod 23 is fixed to the top of the plug-in block 22; the connecting rod 23 extends from one end away from the plug-in block 22 to the outside of the discharge box 5; a paddle 24 is fixed to one end of the connecting rod 23 located on the outside of the discharge box 5; a spring 25 is sleeved on the outside of one end of the connecting rod 23 close to the plug-in block 22; one end of the spring 25 is fixedly connected to the plug-in block 22; the other end of the spring 25 is fixedly connected to the discharge box 5. During operation, when the magnetic adsorption plate 17 needs to be disassembled, first push the paddle 24 upwards so that the paddle 24 drives the plug-in block 22 to move through the connecting rod 23. When the plug-in block 22 moves to disengage from the plug-in slot 21, the plug-in block 22 cancels the limit on the connecting slider 18, so that the connecting slider 18 can be moved out from the inside of the discharge box 5, thereby facilitating the disassembly of the magnetic adsorption plate 17. This step can effectively limit the connecting slider 18 through the structural design of the plug-in block 22, thereby preventing the magnetic adsorption plate 17 and the connecting slider 18 from sliding out from the inside of the discharge box 5, thereby improving the stability of the connecting slider 18 and facilitating the disassembly of the magnetic adsorption plate 17.

[0031] like Figure 5 As shown, a fixing plate 19 is fixed to one end of the connecting slider 18 away from the discharge box 5; a handle 20 is fixed to one end of the fixing plate 19 away from the connecting slider 18. During operation, when the magnetic adsorption plate 17 needs to be disassembled, the handle 20 is first pulled so that the handle 20 drives the connecting slider 18 to move through the fixing plate 19. This step can facilitate the movement of the connecting slider 18 and the magnetic adsorption plate 17, which is convenient for the operator to operate.

[0032] like Figure 1 and Figure 2 As shown, a plurality of exhaust ports 6 are evenly provided on the surface of the cover 4. When the water inside the screw conveyor 10 evaporates during operation, the water vapor can be discharged outward through the exhaust ports 6. This step can effectively discharge the water vapor inside the screw conveyor 10 outward through the structural design of the exhaust ports 6.

[0033] Working principle: before the conveying operation, the smoke inlet 8 is first connected to the exhaust pipe of the incinerator, so that part of the high-temperature flue gas during combustion can enter the heating tube 11 through the smoke inlet 8, and then the inside of the screw conveyor 10 is heated by the heating tube 11, and finally discharged outward through the smoke outlet 9, and then the garbage enters the screw conveyor 10 through the feed port 3 and is transported by the screw conveyor 10 to the direction close to the discharge box 5, and is discharged outward through the discharge box 5. When the garbage enters the inside of the screw conveyor 10, the high heat inside it will evaporate and dry the moisture in the garbage, thereby reducing the moisture in the garbage. Then the garbage is crushed by the crushing component, and then the iron filings and metals contained in the garbage are adsorbed and collected by the adsorption component; when the garbage falls between the two crushing rollers 15 through the screw conveyor 10 and the outer cylinder 1, the motor 12 is started, so that the motor 12 drives the driving gear 13 to rotate, and when the driving gear 13 rotates, the other crushing roller 15 is driven to rotate at the same time through the transmission gear 14, so that the two crushing rollers 15 rotate at the same time, thereby The garbage between the two crushing rollers 15 is crushed; after the garbage is crushed by the two crushing rollers 15, it falls to the top of the baffle 16 and is then discharged downward through the baffle 16; the garbage that falls through the baffle 16 will fall to the top of the magnetic adsorption plate 17 and be sent downward through the magnetic adsorption plate 17. When the garbage passes through the magnetic adsorption plate 17, the magnetic adsorption plate 17 will adsorb the iron filings in the crushed garbage by its own magnetism; when the magnetic adsorption plate 17 needs to be disassembled, first push the paddle 24 upward so that the paddle 24 can be removed. The sheet 24 drives the plug-in block 22 to move through the connecting rod 23. When the plug-in block 22 moves to disengage from the plug-in slot 21, the plug-in block 22 cancels the limit on the connecting slider 18, so that the connecting slider 18 can be moved out from the inside of the discharge box 5, thereby facilitating the disassembly of the magnetic adsorption plate 17; when the magnetic adsorption plate 17 needs to be disassembled, first pull the handle 20 so that the handle 20 drives the connecting slider 18 to move through the fixed plate 19; when the moisture inside the screw conveyor 10 evaporates, the water vapor can be discharged to the outside through the exhaust port 6.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
