TECHNICAL FIELD

[0001] The present application relates to the technical field of garbage feeding, and in particular to a garbage incinerator feeding structure. BACKGROUND

[0002] A garbage incinerator is a device that uses high-temperature combustion technology to process municipal solid waste. It sends garbage into the combustion chamber for combustion at high temperatures, thereby converting waste into heat energy, flue gas and residual ash. Garbage incinerators are usually equipped with flue gas treatment systems to reduce harmful gas emissions and ensure compliance with environmental standards. The device can effectively reduce the volume of garbage, reduce the amount of garbage landfill, and utilize the generated heat energy for power or hot water, with the advantages of environmental protection and energy saving. Before reuse, the garbage needs to be fed into the incinerator through the feeding structure.

[0003] The current garbage incinerator feeding structure can successfully add garbage to the incinerator, but there are some deficiencies in actual operation. First, the existing feeding system cannot effectively isolate the high-temperature flue gas in the combustion chamber during garbage feeding, which may expose the operator to a harmful environment and affect safety. Second, the feeding structure lacks intermittent air (combustion-supporting) function, which cannot accurately control air supply, affecting the efficiency and stability of garbage combustion. In addition, the feeding process does not fully guarantee the safety of the discharging process, which may cause garbage accumulation or jam, thereby reducing the overall operation efficiency and affecting the effect and economy of garbage incineration. To address these issues, the feeding structure needs to be optimized to improve safety, combustion efficiency and operation convenience. Therefore, there is an urgent need to design a garbage incinerator feeding structure. SUMMARY

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Please see the attached Figure 1 -Attached Figure 9, a waste incinerator feeding structure, including a feed hopper 3 for feeding waste, and also including: a transfer bucket 1 and a discharge assembly, the transfer bucket 1 is connected and installed at the bottom of the feed hopper 3, and the transfer bucket 1 is used to discharge waste in batches, the bottom of the transfer bucket 1 is connected and installed with a discharge hopper 4, the end of the discharge hopper 4 is connected and installed with an incinerator 2, the discharge assembly is arranged inside the transfer bucket 1, and the discharge assembly is used to intermittently discharge the waste inside the transfer bucket 1; wherein the discharge assembly includes: a discharge roller 9, a push plate 13 and a U-shaped groove 18, the discharge roller 9 is rotatably installed inside the transfer bucket 1, the discharge roller 9 is a cylinder, and four annular evenly distributed receiving grooves 10 are opened on the surface of the discharge roller 9, and the receiving grooves 10 are used to receive waste Garbage, a driving mechanism is installed on the outer end surface of the transfer bucket 1, and the driving mechanism is a driving motor 6. The output shaft of the driving motor 6 is installed at the center of the end surface of the unloading roller 9. There are four pusher plates 13, and the four pusher plates 13 are respectively slidably arranged inside the four accommodating grooves 10. There are multiple U-shaped grooves 18, and multiple U-shaped grooves 18 are evenly opened at both ends of the multiple accommodating grooves 10. A fourth one-way valve is installed inside each U-shaped groove 18. There are two U-shaped grooves 18 at each end of the accommodating groove 10. The thickness of the pusher plate 13 is adapted to the long side of the U-shaped groove 18, so that the two ends of the U-shaped groove 18 can be respectively located on both sides of the pusher plate 13. The U-shaped groove 18 is used to discharge and guide the gas, and the guided gas can clean the pusher plate 13; Each time the material is fed, it can not only ensure that the garbage is fully discharged, but also provide gas to the incinerator 2 on a regular basis, thereby achieving the purpose of assisting the combustion of the incinerator 2, while avoiding the smoke in the incinerator 2 from overflowing from the feed hopper 3 and affecting the working environment.

[0021] Please see the attached Figure 2 -Attached Figure 9 In a preferred embodiment, filter discs 15 are installed at both ends of each U-shaped groove 18. The filter discs 15 are used to allow gas to pass through the U-shaped groove 18 and prevent impurities from entering the interior of the U-shaped groove 18. Each time the push plate 13 moves, impurities on the surface of the filter disc 15 are cleaned, which is equivalent to scraping, ensuring that the filter disc 15 will not be blocked. A chute 14 is provided at both ends of each accommodating groove 10. A trapezoidal slider 23 is slidably installed inside each chute 14. The end face of the trapezoidal slider 23 is fixedly installed on the end face of the push plate 13, and the trapezoidal slider 23 is a right-angled trapezoidal slider 23. The oblique edge of the trapezoidal slider 23 is used to clean impurities inside the chute 14. It should be noted that the chute 14 and the trapezoidal slider 23 are used to limit the moving path of the push plate 13, and the trapezoidal slider 23 is used to clean the impurities entering the chute 14, thereby ensuring the smooth movement of the trapezoidal slider 23 in the chute 14; A cylindrical groove 16 is formed in the center of the blanking roller 9, and a pipe body 17 is horizontally rotatably installed in the cylindrical groove 16. When the blanking roller 9 rotates, the pipe body 17 can be stationary relative to the blanking roller 9. The surface of the pipe body 17 is linearly and uniformly connected to a plurality of gas injection pipes 20. The gas injection pipes 20 are sealed between the inner wall of the cylindrical groove 16, used to generate high pressure in the pipe body 17, which is equivalent to storing gas at high pressure. The high pressure formed will spray gas to clean the garbage, which helps to improve the cleaning effect of the pushing plate 13. A plurality of annularly and uniformly distributed communication holes 19 are formed in the inner wall of the cylindrical groove 16. Each communication hole 19 is connected to the corresponding holding groove 10, so that the gas in the pipe body 17 can enter the holding groove 10 through the communication hole 19. A plurality of annularly and uniformly distributed second exhaust holes 12 are also formed in the inner wall of the cylindrical groove 16, and each second exhaust hole 12 penetrates the blanking roller 9. A third one-way valve is installed on each second exhaust hole 12, which allows gas to flow from the cylindrical groove 16 to the second exhaust hole 12 only, preventing smoke from overflowing from the second exhaust hole 12 to the outside. The second exhaust hole 12 and the communication hole 19 are arranged in a staggered manner. A plurality of first exhaust holes 8 are formed in the side of the transfer hopper 1, and the corresponding first exhaust holes 8 are connected to the second exhaust holes 12. The first exhaust hole 8 and the second exhaust hole 12 are used to exhaust the gas when the pushing plate 13 is reset, ensuring that the pushing plate 13 can be reset smoothly, avoiding the situation that the pushing plate 13 and the gas in the holding groove 10 cannot be exhausted, causing the pushing plate 13 to be unable to reset.

[0022] Please refer to the accompanying Figure 1 -attached Figure 9 In a preferred embodiment, a gas tank 5 is fixedly installed on the side of the transfer hopper 1. An air outlet pipe 11 is connected to the side of the gas tank 5. The end of the air outlet pipe 11 penetrates the end face of the transfer hopper 1 and the end face of the blanking roller 9, and is connected to the pipe body 17. A second one-way valve is installed on the air outlet pipe 11, which allows the gas in the gas tank 5 to be exhausted through the air outlet pipe 11. An air inlet pipe 21 is connected to the surface of the gas tank 5, and a first one-way valve is installed on the air inlet pipe 21, which allows only external gas to enter the gas tank 5 through the air inlet pipe 21. A piston plate 22 is slidably installed in the gas tank 5. An electric telescopic rod 7 is installed on the top of the gas tank 5, and the telescopic end of the electric telescopic rod 7 penetrates the top of the gas tank 5 and is installed on the top of the piston plate 22. When it is necessary to add garbage to the incinerator 2, the garbage is first placed in the feed hopper 3, and then the garbage enters the holding groove 10 connected to the feed hopper 3. Then start the drive motor 6 and the electric telescopic rod 7 to drive the unloading roller 9 to rotate. It should be noted that the drive motor 6 is a 90-degree intermittent motor, and when the drive motor 6 rotates 90 degrees, the electric telescopic rod 7 extends and retracts once, and the unloading roller 9 rotates to drive the four receiving slots 10 to rotate, so that the receiving slots 10 with garbage will be separated from the unloading hopper 4, and the transfer bucket 1 will seal the receiving slots 10, ensuring that when the unloading roller 9 rotates, the smoke in the incinerator 2 will not enter the transfer bucket 1 and the feeding hopper 3 through the unloading hopper 4, so that the smoke will not overflow from the feeding hopper and affect the staff; When the telescopic end of the electric telescopic rod 7 retracts, it drives the piston plate 22 to move upward. The upward movement of the piston plate 22 opens the first one-way valve on the air inlet pipe 21, and the external gas enters the air box 5 from the air inlet pipe 21. When the telescopic end of the electric telescopic rod 7 is extended, it drives the piston plate 22 to move downward. When the piston plate 22 moves downward, the second one-way valve on the air outlet pipe 11 opens, and the gas inside the air box 5 enters the tube body 17 and the air injection pipe 20 through the inlet pipe. Since the air injection pipe 20 is not connected with the communicating hole 19 during the rotation of the blanking roller 9, the air injection pipe 20 is sealed with the inner wall of the cylindrical groove 16, causing the gas to accumulate inside the tube body 17 to form a high pressure. Until the blanking roller 9 rotates ninety degrees, the air injection pipe 20 is connected with the communicating pipe, and the gas inside the tube body 17 enters the interior of the receiving tank 10 through the communicating hole 19; When the holding tank 10 with garbage is transferred to the vertical downward position and connected to the lower hopper 4, the high-pressure gas ejected through the connecting pipe will push the push plate 13 to move downward. The push plate 13 moves downward and drives the garbage in the holding tank 10 to pass through the lower hopper 4 into the incinerator 2, completing the feeding of the garbage and avoiding the situation where the garbage in the holding tank 10 is stuck in the holding tank 10 and cannot be discharged; When the trapezoidal slider 23 follows the push plate 13 to move to the maximum stroke, the push plate 13 will be located between the two ends of the U-shaped groove 18, and then the gas inside the receiving tank 10 will be ejected through the U-shaped groove 18. Due to the guide setting of the U-shaped groove 18, the high-pressure gas ejected from the U-shaped groove 18 will clean the bottom surface of the push plate 13 that receives garbage, ensuring that all the garbage inside the receiving tank 10 can enter the incinerator 2; In addition, the gas ejected through the U-shaped groove 18 will also provide oxygen to the incinerator 2 to assist combustion. When the push plate 13 is at the end of the receiving groove 10, the receiving groove 10 is blocked, and the flue gas in the incinerator 2 will not enter the interior of the receiving groove 10. It should be noted that a fourth one-way valve is installed inside the U-shaped groove 18, which ensures that the gas can only enter from the end of the U-shaped groove 18 close to the cylindrical groove 16 and eject from the end away from the cylindrical groove 16, thereby preventing the flue gas from entering the interior of the receiving groove 10 through the U-shaped tube. Then, as the unloading roller 9 continues to rotate, the receiving groove 10 after unloading will be connected to the feed hopper 3 again. At this time, the corresponding first exhaust hole 8 will be connected to the first exhaust hole 8, and the garbage will squeeze the push plate 13, causing the push plate 13 to move downward and reset. When the push plate 13 is reset, the gas inside it will be discharged to the outside from the second exhaust hole 12 and the first exhaust hole 8, ensuring that the push plate 13 can be reset smoothly.

[0023] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
