Technical Field
[0001] This invention relates to the field of waste treatment technology, and more particularly to a device for treating solid waste. Background Technology
[0002] Solid waste, also known as fixed waste, refers to solid or semi-solid substances generated during production, daily life, and other activities that have lost their original utilization value or have been discarded or abandoned even if they have not lost their utilization value. Currently, fixed waste is often treated by incinerators, which oxidize and decompose it at high temperatures, converting it into ash, gas, and heat energy. Its core purpose is to significantly reduce the volume of waste, completely eliminate pathogens and harmful organic matter, recover energy, and achieve safe disposal of waste.
[0003] In the operation of incinerators, auxiliary fuel, often liquefied natural gas (LNG), is frequently used to maintain furnace temperature and ensure combustion stability. Injecting LNG into the combustion furnace supplements energy. While the overall structure is simple, in actual use, firstly, the nozzle position is fixed. Preheating is required before spraying auxiliary combustion, as the nozzle is located in a lower-temperature area within the combustion chamber, consuming significant energy for heating. Secondly, the fixed nozzle position means the sprayed area is also fixed, sometimes failing to receive timely energy replenishment. Thirdly, the fixed spray volume during spraying easily leads to "carbon-coated oil," wasting calorific value and generating CO. Furthermore, to ensure complete combustion, manual agitation of the waste within the combustion chamber is necessary, which is time-consuming, labor-intensive, troublesome, and poses certain risks. Therefore, this paper proposes a solid waste treatment device. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a solid waste treatment device.
[0005] The present invention adopts the following technical solution:
[0006] A solid waste treatment device includes a fixed box, a combustion box fixedly connected to the fixed box, an exhaust pipe fixedly connected to the combustion box, a feed pipe fixedly connected to the combustion box, a conveying pipe fixedly connected through the combustion box, a hydraulic cylinder fixedly connected to the combustion box, an annular pipe fixedly connected to the hydraulic cylinder, the annular pipe communicating with the conveying pipe, a plurality of flexible hoses fixedly connected inside the annular pipe, a nozzle fixedly connected to the plurality of flexible hoses, a plurality of clamping plates fixedly connected to the annular pipe, the clamping plates being in pairs, each pair of clamping plates and a nozzle facing each other, a rotating shaft rotatably connected between each pair of clamping plates, the rotating shaft being fixedly connected to the nozzle, a first torsion spring fixedly connected between the clamping plate and the nozzle, and a control component for controlling the rotation of the nozzles fixedly connected to the annular pipe.
[0007] Preferably, the control assembly includes multiple movable plates fixedly installed on the lower side of the annular tube. The position and number of the movable plates are opposite to the nozzle. Multiple round rods are slidably connected through the movable plates. Multiple triangular blocks are uniformly fixedly connected to the combustion chamber. Threaded rods are rotatably connected to the round rods. Movable rings are fixedly connected to the threaded rods. Multiple protrusions are circumferentially fixedly connected to the movable rings. Conical heads are also fixedly connected to the movable rings. Tension springs are fixedly connected to the movable rings. Connecting rings are fixedly connected to the tension springs. The connecting rings and movable plates are rotatably connected.
[0008] Preferably, the nozzle is rotatably connected to a rotating ring, the rotating ring is fixedly connected to a baffle via a connecting rod, a second torsion spring is fixedly connected between the rotating ring and the nozzle, and a connecting ball is fixedly connected to the rotating ring.
[0009] Preferably, the threaded rod is threadedly connected to a threaded cylinder, and the threaded cylinder and the movable plate are fixedly connected.
[0010] Preferably, a filter plate is snapped between the combustion chamber and the fixing chamber, and the filter plate has multiple filter holes evenly distributed on its upper side.
[0011] Preferably, a slide rail is fixedly connected to the outside of the fixed box, and a slide plate is slidably connected to the upper side of the slide rail. The slide plate is opposite to the fixed box, and an observation window is fixedly installed on the side wall of the slide plate. Multiple rotating rods are threadedly connected to the side wall of the fixed box, and a sealing plate is rotatably connected to the outside of each rotating rod.
[0012] Preferably, the exhaust pipe is equipped with multiple filter elements, the exhaust pipe and the combustion chamber are rotatably connected by multiple mounting bolts, and a sealing ring is installed between the exhaust pipe and the combustion chamber.
[0013] The beneficial effects of this invention are:
[0014] 1. First, during the combustion of solid waste, when additional heat energy is needed, liquefied natural gas is introduced into the ring pipe through the delivery pipe. The liquefied natural gas is sprayed out through the nozzle. During this process, the hydraulic cylinder is activated, which drives the ring pipe to move up and down. During this process, the liquefied natural gas sprayed out by the nozzle is sprayed into the combustion chamber, which can supplement the heat in the combustion chamber and keep the combustion chamber at a suitable temperature.
[0015] 2. Furthermore, during the up-and-down movement of the annular tube, the round rod moves back and forth relative to the moving plate. During this process, when the uppermost moving ring comes into contact with the nozzle, the nozzle rotates around the pivot, which allows the nozzle to spray a wider range of liquefied natural gas, providing better heat to different locations within the combustion chamber 2 and further reducing the occurrence of "carbon encapsulation". In addition, during this process, the lower the cone head penetrates deeper into the solid waste, breaking down the combustible material and making the solid waste burn more completely.
[0016] 3. Then, as the round rod moves relative to the moving plate, the moving ring and the conical head rotate and also rotate on their own axis. This not only improves the agitation of waste by the conical head, but also causes the connecting ball and the rotating ring to rotate relative to the nozzle when the protrusion and the connecting ball abut against each other. The nozzle drives the baffle to rotate through the connecting rod. Since the baffle is on the outside of the nozzle, when the baffle rotates relative to the nozzle, it will cause the actual spraying area of the nozzle to change, which can further reduce the occurrence of the "carbon coating oil" phenomenon.

Detailed Implementation
[0028] See Figures 1-10 A solid waste treatment device includes a fixed box 1, a combustion box 2 fixedly connected to the upper side of the fixed box 1, and a filter plate 8 clamped between the combustion box 2 and the fixed box 1. The filter plate 8 has multiple evenly spaced filter holes on its upper side. During and after combustion, the waste residue can pass through the filter plate 8 and fall into the fixed box 1, completing the waste residue collection operation. An exhaust pipe 4 is fixedly connected to the upper side of the combustion box 2. Multiple filter elements are installed inside the exhaust pipe 4. Multiple mounting bolts rotatably connect the exhaust pipe 4 and the combustion box 2, and a sealing ring is installed between the exhaust pipe 4 and the combustion box 2. The air after combustion is filtered through the filter elements (which also contain various different filter materials, such as activated carbon), removing most of the harmful substances. The combustion box 2 and the exhaust pipe 4 are fixed together by the mounting bolts. After a period of operation, the exhaust pipe 4 can be removed and the filter elements inside the exhaust pipe 4 replaced, allowing the exhaust pipe 4 to continuously and effectively treat the air after combustion.
[0029] A slide rail is fixedly connected to the outside of the fixed box 1, and a sliding plate is slidably connected to the upper side of the slide rail. The sliding plate is opposite to the fixed box 1, and an observation window is fixedly installed on the side wall of the sliding plate. Multiple rotating rods are threadedly connected to the side wall of the fixed box 1, and a sealing plate is rotatably connected to the outside of each rotating rod. After waste residue falls into the fixed box 1, when there is too much waste residue in the fixed box 1, the sliding plate can be moved to open the fixed box 1, thereby cleaning the waste residue inside the fixed box 1. Furthermore, through the rotating rods and sealing plates, the connection between the sliding plate and the fixed box 1 can be made tighter, reducing heat loss.
[0030] A feed pipe 3 is fixedly connected to the side wall of the combustion chamber 2. A conveying pipe 5 is fixedly connected through the side wall of the combustion chamber 2. A hydraulic cylinder 7 is fixedly connected to the upper side of the combustion chamber 2. The output end of the hydraulic cylinder 7 passes through the combustion chamber 2 and is fixedly connected to an annular pipe 6. The annular pipe 6 and the conveying pipe 5 are connected. Multiple hoses 12 are fixedly connected inside the annular pipe 6. A nozzle 13 is fixedly connected to the outside of the multiple hoses 12. Multiple clamping plates 22 are fixedly connected to the outside of the annular pipe 6. The multiple clamping plates 22 are in pairs, and each pair of clamping plates 22 is opposite to the nozzle 13. A rotating shaft 24 is rotatably connected between each pair of clamping plates 22. The rotating shaft 24 is fixedly connected to the nozzle 13. A first torsion spring 25 is fixedly connected between the clamping plates 22 and the nozzle 13.
[0031] First, a rotating plate matching the feed pipe 3 is installed on the outside of the feed pipe 3. By rotating the rotating plate, the opening and closing control of the feed pipe 3 can be completed. Second, the output end of the hydraulic cylinder 7 slides through the side wall of the combustion chamber 2, and a sealing element (such as a silicon ceramic fiber sealing gasket, which can achieve a sealing effect in high-temperature environments) is installed between the combustion chamber 2 and the hydraulic cylinder 7. Then, the conveying pipe 5 is a high-temperature resistant and non-flammable hose, such as a stainless steel hose, and the conveying pipe 5 is longer on one side inside the combustion chamber 2. Figure 3 , Figure 4 The middle section only represents the part of the conveying pipe 5 located inside the combustion chamber 2. The conveying pipe 5 does not affect the normal up-and-down movement of the annular pipe 6. Finally, when solid waste needs to be treated, the solid waste to be treated is put into the combustion chamber 2 and the combustion operation can be started. After burning for a period of time, when energy needs to be replenished, liquefied natural gas is introduced into the annular pipe 6 through the conveying pipe 5. The liquefied natural gas is sprayed out through the nozzle 13. During this process, the hydraulic cylinder 7 is activated, and the hydraulic cylinder 7 drives the annular pipe 6 to move downward. After a period of time, the hydraulic cylinder 7 is activated again, and the hydraulic cylinder 7 drives the annular pipe 6 to move upward. During the up-and-down movement of the annular pipe 6, the liquefied natural gas sprayed out by the nozzle 13 is sprayed into the combustion chamber 2, which can replenish the heat in the combustion chamber 2 and keep the combustion chamber 2 at a suitable temperature.
[0032] A control assembly for controlling the rotation of the nozzle 13 is fixedly connected to the outside of the annular tube 6. The control assembly includes multiple movable plates 9 fixedly installed on the lower side of the annular tube 6. The position and number of movable plates 9 are opposite to the nozzle 13. Multiple round rods 10 are slidably connected through the side wall of the movable plate 9. Multiple triangular blocks 11 are evenly fixedly connected to the side wall of the combustion chamber 2. A threaded rod 23 is rotatably connected to the side of the round rod 10 away from the triangular block 11. A movable ring 16 is fixedly connected to the outside of the threaded rod 23. Multiple protrusions 17 are circumferentially fixedly connected to the side wall of the movable ring 16. A conical head 14 is also fixedly connected to the outside of the movable ring 16. A tension spring 18 is fixedly connected to the side wall of the movable ring 16. A connecting ring 28 is fixedly connected to the other side of the tension spring 18. The connecting ring 28 and the movable plate 9 are rotatably connected.
[0033] During the up-and-down movement of the annular pipe 6, the annular pipe 6 drives the moving plate 9 to move up and down, and the moving plate 9 drives the round rod 10 to move up and down. During this process, when the round rod 10 and the triangular block 11 abut against each other, the round rod 10 will move back and forth relative to the moving plate 9 due to the obstruction of the triangular block 11. With the cooperation of the tension spring 18, the round rod 10 drives the moving ring 16 and the conical head 14 to move back and forth relative to the moving plate 9 through the threaded rod 23. During this process, when the uppermost moving ring 16 moves, the protrusion 17 on the outer side of the moving ring 16 abuts against the nozzle 13, causing the nozzle 13 to rotate around the pivot 24. This allows the nozzle 13 to spray a wider range during the spraying of liquefied natural gas, providing better heat to different locations in the combustion chamber 2 and further reducing the occurrence of "carbon coating on oil". In addition, the lower the conical head 14, the deeper it will penetrate into the solid waste. The conical head 14 will destroy the combustibles, making the solid waste burn more completely.
[0034] A rotating ring 26 is rotatably connected to the outside of the nozzle 13. A baffle 21 is fixedly connected to the upper side of the rotating ring 26 via a connecting rod 20. A second torsion spring 27 is fixedly connected between the rotating ring 26 and the nozzle 13. A connecting ball 19 is fixedly connected to the lower side of the rotating ring 26. A threaded cylinder 15 is threadedly connected to the outside of the threaded rod 23. The threaded cylinder 15 is fixedly connected to the moving plate 9.
[0035] First, during the movement of the round rod 10 relative to the moving plate 9, due to the sliding connection between the round rod 10 and the moving plate 9, the threaded rod 23 will rotate under the action of the threaded cylinder 15 and the threaded rod 23. The threaded rod 23 will drive the moving ring 16 and the conical head 14 to rotate, which will not only improve the agitation of waste by the conical head 14, but also cause the rotating moving ring 16 to drive the protrusion 17 to rotate. When the rotating protrusion 17 abuts against the connecting ball 19, the connecting ball 19 and the rotating ring 26 will rotate relative to the nozzle 13. The rotating ring 26 will drive the baffle 21 to rotate through the connecting rod 20. Since the baffle 21 is on the outside of the nozzle 13, when the baffle 21 rotates relative to the nozzle 13, the actual spray area of the nozzle 13 will change, which can further reduce the occurrence of the "carbon coating oil" phenomenon.
[0036] In this invention, when solid waste needs to be treated, the solid waste to be treated is placed into the combustion chamber 2 and combustion is started. After combustion for a period of time, when energy needs to be replenished, liquefied natural gas is introduced into the annular pipe 6 through the delivery pipe 5. The liquefied natural gas is sprayed out through the nozzle 13. During this process, the hydraulic cylinder 7 is activated, and the hydraulic cylinder 7 drives the annular pipe 6 to move downward. After a period of time, the hydraulic cylinder 7 is activated again, and the hydraulic cylinder 7 drives the annular pipe 6 to move upward. During the up and down movement of the annular pipe 6, the liquefied natural gas sprayed out by the nozzle 13 is sprayed into the combustion chamber 2, which can replenish the heat in the combustion chamber 2 and keep the combustion chamber 2 at a suitable temperature.
[0037] During the up-and-down movement of the annular pipe 6, the annular pipe 6 drives the moving plate 9 to move up and down, and the moving plate 9 drives the round rod 10 to move up and down. During this process, when the round rod 10 and the triangular block 11 abut against each other, the round rod 10 will move back and forth relative to the moving plate 9 due to the obstruction of the triangular block 11. With the cooperation of the tension spring 18, the round rod 10 drives the moving ring 16 and the conical head 14 to move back and forth relative to the moving plate 9 through the threaded rod 23. During this process, when the uppermost moving ring 16 moves, the protrusion 17 on the outer side of the moving ring 16 abuts against the nozzle 13, causing the nozzle 13 to rotate around the pivot 24. This allows the nozzle 13 to spray a wider range during the spraying of liquefied natural gas, providing better heat to different locations in the combustion chamber 2 and further reducing the occurrence of "carbon-coated oil". In addition, the lower the conical head 14, the deeper it will penetrate into the solid waste. The conical head 14 will destroy the combustibles, making the solid waste burn more completely.
[0038] During the movement of the round rod 10 relative to the moving plate 9, due to the sliding connection between the round rod 10 and the moving plate 9, the threaded rod 23 will rotate under the action of the threaded cylinder 15 and the threaded rod 23. The threaded rod 23 will drive the moving ring 16 and the conical head 14 to rotate, which will not only improve the agitation of waste by the conical head 14, but also cause the rotating moving ring 16 to drive the protrusion 17 to rotate. When the rotating protrusion 17 abuts against the connecting ball 19, the connecting ball 19 and the rotating ring 26 will rotate relative to the nozzle 13. The nozzle 13 will drive the baffle 21 to rotate through the connecting rod 20. Since the baffle 21 is on the outside of the nozzle 13, when the baffle 21 rotates relative to the nozzle 13, the actual spray area of the nozzle 13 will change, which can further reduce the occurrence of "carbon coating oil".
