[0001] The utility model relates to the technical field of pusher, in particular to a pusher for an incinerator. Background Technique
[0002] A pusher is a device used to push and control the flow of materials in an incinerator, which is used to control the flow and uniform distribution of materials in the combustion chamber. By pushing and controlling the position of materials, it ensures the full combustion of fuel and the flue gas emissions meet environmental protection standards.
[0003] The conventional design of the pusher device is inclined at 5° as a whole to facilitate the transportation of garbage to the incinerator considering the gravity factor. At present, when the water content of the garbage entering the furnace is relatively high, leachate often overflows, and the gap of the surface guard plate of the pusher is too small, so serious coking occurs inside the ash hopper, which is difficult to clean. Occasionally, it will also cause a fire in the drying section, causing great trouble to operation and maintenance. Therefore, this application provides a pusher for an incinerator to meet the requirements. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a pusher for an incinerator to solve the problems that when the water content of the garbage entering the furnace is relatively high, leachate often overflows in the slag hopper of the drying section, so serious coking occurs inside the ash hopper, which is difficult to clean. Occasionally, it will also cause a fire in the drying section, causing great trouble to operation and maintenance.
[0005] To solve the above technical problems, the utility model provides the following technical solutions:
[0006] A pusher for an incinerator includes a bottom shell. A protective shell and a plurality of electric telescopic rods are fixedly connected to the top of the bottom shell. A feeding groove for garbage to pass through is opened at the top of the protective shell. The top of the electric telescopic rod is rotatably connected to a placement platform. A hydraulic press is fixedly connected to the top of the placement platform. The output end of the hydraulic press is fixedly connected to an output shaft. One end of the output shaft away from the hydraulic press extends into the protective shell and is equipped with a pushing mechanism. The pushing mechanism includes an upper slider. A lower slider is fixedly connected to one side of the upper slider away from the output shaft. Rotatable connecting bars are arranged on both sides of the lower slider. Cylinders are rotatably connected to the inner walls of both sides of the protective shell. One ends of the cylinders close to each other are fixedly connected to the same baffle. Sliding grooves are opened on the connecting bars. The cylinders are slidably connected to the sliding grooves. A fixing block is fixedly connected to the bottom of the connecting bar. A connecting column that can abut against the side of the baffle away from the lower slider is fixedly connected between the fixing blocks. A scraper that can abut against the top of the upper slider is fixedly connected to the inner wall of the top of the protective shell. Two support blocks fixedly connected to the inner walls of both sides of the protective shell respectively abut against the side of the baffle away from the lower slider.
[0007] Preferably, a plurality of first through grooves penetrating the upper slider are formed in the upper slider, the gap of the first through grooves is 10 mm, and a plurality of grooves facilitating the flow of leachate are formed at the top of the lower slider.
[0008] Preferably, a second through groove is formed in the placement platform below the upper slider, and a plurality of holes are formed in the placement platform below the baffle.
[0009] Preferably, a collection hopper penetrating the bottom shell is arranged below the second through groove, a pipeline communicated with the holes is arranged below the holes, and one end of the pipeline far away from the holes is communicated with the inside of the collection hopper.
[0010] Preferably, a plurality of H-shaped steels are installed inside the bottom shell, and the H-shaped steels are all located below the electric telescopic rods.
[0011] Preferably, a refractory block for isolating the flame of the incinerator is fixedly connected to one side of the bottom shell.
[0012] Compared with the prior art, the utility model has at least the following beneficial effects:
[0013] In the above scheme, by setting up a pushing mechanism, before operation, first control the length of the electric telescopic rod to level or tilt the placement platform. During operation, the placement platform is tilted, and the hydraulic press controls the output shaft to push the upper slider on the placement platform. At this time, the top of the upper slider collides with the scraper, and the garbage falls from the feed chute on the protective shell onto the upper slider and moves in the direction of the lower slider under the influence of gravity until the garbage contacts the scraper and is blocked on the top of the upper slider. At this time, a certain amount of leachate in the garbage will drip from the through slot 1 on the upper slider and pass through the through slot 2. The gap of the through slot 1 is expanded to 10mm, allowing the leachate to be more The good ones drip from the through slot one and are discharged in time. The upper slider will shrink back after pushing the upper slider to the top. When the side of the upper slider fixedly connected to the lower slider shrinks to the point where it no longer conflicts with the scraper, the garbage will fall from the space between the upper slider and the scraper to the top of the lower slider. Under the influence of gravity, the garbage will continue to move until it falls from the lower slider to the top of the placement platform. During the movement of the garbage, the hydraulic press has been controlling the output shaft to push and pull the upper slider. When the upper slider moves, it will drive the lower slider to move, and when the lower slider moves, it will drive the connecting bar. When the connecting bar moves, the cylinder slides inside the chute, and the connecting column at the bottom of the connecting bar will drive The baffle rotates, so that when the hydraulic press controls the output shaft to pull the upper slider to retract, the baffle is in an open state where it does not conflict with the top of the placement platform. When the hydraulic press controls the output shaft to push the upper slider, the baffle is in a closed state where it conflicts with the top of the placement platform. In the closed state, the baffle will also conflict with the support block, allowing the support block to limit the rotation of the baffle. When the garbage falls to the top of the placement platform, the output shaft pushes the upper slider to make the baffle conflict with the top of the placement platform and become closed. The lower slider will cooperate with the baffle to squeeze the garbage on the top of the placement platform, squeezing out the leachate in the garbage. The squeezed leachate will drip from the hole. When the shaft pulls the upper slider to contract, the lower slider drives the baffle to open through the connecting strip. At this time, the garbage will fall from the placement platform through the opened baffle and start to be incinerated in the incinerator. The advantage of this is that when the moisture content of the garbage is high, the leachate will first drip from the expanded groove 1 on the upper slider into the groove 2 on the placement platform. After the garbage falls on the top of the placement platform, the lower slider and the baffle will cooperate to squeeze out the excess leachate and let the leachate drip from the holes, so that the moisture of the garbage entering the furnace is discharged in time, effectively reducing the frequency of coke cleaning, thereby reducing the input of coke cleaning labor and reducing the risk of fire.
[0014] By setting up a collecting bucket and a pipe, when the leachate drips from the groove 1 on the upper slider into the groove 2 on the placement platform, it will be directly caught by the collecting bucket, and the leachate dripping from the hole will directly enter the pipe and then flow into the interior of the collecting bucket from the pipe, which is convenient for collecting the leachate, reduces the environmental impact caused by the overflow of the leachate, and reduces the corrosion of downstream equipment. By setting up H-shaped steel, the load-bearing capacity of the bottom shell on the electric telescopic rod is enhanced, which facilitates the movement of the upper slider, the lower slider and the garbage entering the furnace.

[0024] As Figures 1-4As shown in the figure, an embodiment of the utility model provides a pusher for an incinerator, which includes a bottom shell 1. A protective shell 3 and a plurality of electric telescopic rods 4 are fixedly connected to the top of the bottom shell 1. A feeding groove for garbage to pass through is opened at the top of the protective shell 3. The top of the electric telescopic rod 4 is rotatably connected to a placement platform 5. A hydraulic press 6 is fixedly connected to the top of the placement platform 5. The output end of the hydraulic press 6 is fixedly connected to an output shaft 7. One end of the output shaft 7 away from the hydraulic press 6 extends into the protective shell 3 and is provided with a pushing mechanism 8. The pushing mechanism 8 includes an upper slider 801. A lower slider 803 is fixedly connected to one side of the upper slider 801 away from the output shaft 7. Rotatable connecting bars 805 are arranged on both sides of the lower slider 803. Cylinders 807 are rotatably connected to the inner walls on both sides of the protective shell 3. One ends of the cylinders 807 close to each other are fixedly connected to the same baffle 808. A chute 806 is opened on the connecting bar 805. The cylinder 807 is slidably connected to the chute 806. A fixed block 809 is fixedly connected to the bottom of the connecting bar 805. A connecting column 810 that can abut against the side of the baffle 808 away from the lower slider 803 is fixedly connected between the fixed blocks 809. A scraper 13 that can abut against the top of the upper slider 801 is fixedly connected to the inner wall of the top of the protective shell 3. Two support blocks 14 fixedly connected to the inner walls on both sides of the protective shell 3 respectively abut against the side of the baffle 808 away from the lower slider 803. A plurality of through grooves 802 penetrating the upper slider 801 are opened on the upper slider 801. The gap of the through groove 802 is 10 mm. A plurality of grooves 804 facilitating the flow of leachate are opened at the top of the lower slider 803. A through groove 11 is opened on the placement platform 5 below the upper slider 801. A number of holes 12 are opened on the placement platform 5 below the baffle 808 near it.
[0025] By setting the pushing mechanism 8, before operation, first control the length of the electric telescopic rod 4 to level or tilt the placement platform 5. During operation, tilt the placement platform 5, and the hydraulic press 6 controls the output shaft 7 to push the upper slider 801 on the placement platform 5. At this time, the top of the upper slider 801 conflicts with the scraper 13, and the garbage falls from the feed trough on the protective shell 3 onto the upper slider 801 and moves in the direction of the lower slider 803 under the influence of gravity until the garbage contacts the scraper 13 and is blocked on the top of the upper slider 801. At this time, a certain amount of leachate in the garbage will drip from the through groove 1 802 on the upper slider 801 and pass through the through groove 2 11. The gap of the through groove 1 802 is expanded to 10 mm, allowing the leachate to drip better from the through groove 1 802 , so as to be discharged in time, the upper slider 801 will retract after pushing the upper slider 801 to the top, and when the side of the upper slider 801 fixedly connected to the lower slider 803 retracts to the point where it no longer conflicts with the scraper 13, the garbage will fall from the space between the upper slider 801 and the scraper 13 to the top of the lower slider 803, and the garbage will continue to move under the influence of gravity until it falls from the lower slider 803 to the top of the placement platform 5. During the process of garbage movement, the hydraulic press 6 has been controlling the output shaft 7 to push and pull the upper slider 801. When the upper slider 801 moves, it will drive the lower slider 803 to move, and when the lower slider 803 moves, it will drive the connecting bar 805. When the connecting bar 805 moves, the cylinder 807 slides inside the slide groove 806, and the connecting column 81 at the bottom of the connecting bar 805 0 will drive the baffle 808 to rotate, so that when the hydraulic press 6 controls the output shaft 7 to pull the upper slider 801 to retract, the baffle 808 is in an open state where it does not conflict with the top of the placement platform 5. When the hydraulic press 6 controls the output shaft 7 to push the upper slider 801, the baffle 808 is in a closed state where it conflicts with the top of the placement platform 5. In the closed state, the baffle 808 will also conflict with the support block 14, allowing the support block 14 to limit the rotation of the baffle 808. When the garbage falls to the top of the placement platform 5, the output shaft 7 pushes the upper slider 801 to make the baffle 808 conflict with the top of the placement platform 5 and become closed. The lower slider 803 will cooperate with the baffle 808 to squeeze the garbage on the top of the placement platform 5, squeezing out the leachate in the garbage, and the squeezed leachate will flow out from the hole The garbage will first fall from the expanded through groove 1 802 on the upper slider 801 into the through groove 2 11 on the placement platform 5. After the garbage falls on the top of the placement platform 5, the lower slider 803 and the baffle 808 will cooperate to squeeze out the excess leachate and let the leachate drip from the hole 12, so that the moisture of the garbage entering the furnace can be discharged in time, which effectively reduces the frequency of coke cleaning, thereby reducing the input of labor for coke cleaning and reducing the risk of fire.

One end of the pipe 9 away from the hole 12 communicates with the inside of the collection hopper 10. A plurality of H-shaped steels 2 are installed inside the bottom shell 1, and the H-shaped steels 2 are all located below the electric telescopic rod 4. A refractory block 15 for isolating the flame of the incinerator is fixedly connected to one side of the bottom shell 1. By providing the collection hopper 10 and the pipe 9, when the leachate drips from the first through groove 802 on the upper slider 801 into the second through groove 11 on the placement platform 5, it will be directly received by the collection hopper 10, and the leachate dripping from the hole 12 will directly enter the pipe 9 and then flow into the inside of the collection hopper 10 from the pipe 9, facilitating the collection of the leachate, reducing the environmental impact problem caused by the overflow of the leachate, and reducing the corrosion of downstream equipment. By providing the H-shaped steels 2, the load-bearing capacity of the bottom shell 1 for the electric telescopic rod 4 is strengthened, facilitating the movement operation of the upper slider 801, the lower slider 803 and the waste entering the furnace.

Before operation, the length of the electric telescopic rod 4 is first controlled to level or tilt the placement platform 5. During operation, the placement platform 5 is tilted, and the hydraulic press 6 controls the output shaft 7 to push the upper slider 801 on the placement platform 5. At this time, the top of the upper slider 801 conflicts with the scraper 13, and the garbage falls from the feed trough on the protective shell 3 onto the upper slider 801 and moves in the direction of the lower slider 803 under the influence of gravity until the garbage contacts the scraper 13 and is blocked on the top of the upper slider 801. At this time, a certain amount of leachate in the garbage will drip from the through groove 1 802 on the upper slider 801 and pass through the through groove 2 11. The gap of the through groove 1 802 is expanded to 10 mm, allowing the leachate to be better The garbage will drip from the through slot 1 802 and be discharged in time. The upper slider 801 will shrink back after pushing the upper slider 801 to the top. When the side of the upper slider 801 fixedly connected to the lower slider 803 shrinks to the point where it no longer conflicts with the scraper 13, the garbage will fall from the space between the upper slider 801 and the scraper 13 to the top of the lower slider 803. Under the influence of gravity, the garbage will continue to move until it falls from the lower slider 803 to the top of the placement platform 5. During the garbage movement, the hydraulic press 6 has been controlling the output shaft 7 to push and pull the upper slider 801. When the upper slider 801 moves, it will drive the lower slider 803 to move. When the lower slider 803 moves, it will drive the connecting bar 805. When the connecting bar 805 moves, the cylinder 807 slides inside the slide groove 806, and the bottom of the connecting bar 805 The connecting column 810 at the top will drive the baffle 808 to rotate, so that when the hydraulic press 6 controls the output shaft 7 to pull the upper slider 801 to retract, the baffle 808 is in an open state that does not conflict with the top of the placement platform 5. When the hydraulic press 6 controls the output shaft 7 to push the upper slider 801, the baffle 808 is in a closed state that conflicts with the top of the placement platform 5. In the closed state, the baffle 808 will also conflict with the support block 14, allowing the support block 14 to limit the rotation of the baffle 808. When the garbage falls to the top of the placement platform 5, the output shaft 7 pushes the upper slider 801 to make the baffle 808 conflict with the top of the placement platform 5 and become closed. The lower slider 803 will cooperate with the baffle 808 to squeeze the garbage on the top of the placement platform 5, squeeze out the leachate in the garbage, and the squeezed out leachate It will drip from the hole 12. When the output shaft 7 pulls the upper slider 801 to contract, the lower slider 803 drives the baffle 808 to open through the connecting strip 805. At this time, the garbage will fall from the placement platform 5 through the opened baffle 808 and start to be incinerated in the incinerator. The advantage of this is that when the moisture content of the garbage is high, the leachate will first drip from the expanded groove 1 802 on the upper slider 801 into the groove 2 11 on the placement platform 5. After the garbage falls on the top of the placement platform 5, the lower slider 803 and the baffle 808 will cooperate to squeeze out the excess leachate and let the leachate drip from the hole 12, so that the moisture of the garbage entering the furnace is discharged in time, effectively reducing the frequency of coke cleaning, thereby reducing the input of coke cleaning labor and reducing the risk of fire.
