Description

Technical Field

[0001] This utility model relates to the technical field of environmental protection equipment, and in particular to a feeding device for a small-scale waste incinerator. Background Technology

[0002] Decentralized disposal of municipal solid waste, especially small-scale incinerators, has advantages in rural areas, but it needs to meet requirements such as waste adaptability, incineration thoroughness, and pollutant emissions, and also needs to consider reliability and ease of operation.

[0003] The incinerator's feeding mechanism is not only responsible for delivering waste into the furnace but also for its airlock function, preventing flue gas leakage and the entry of outside air. However, waste retention and adhesion at the feed inlet can lead to coking, feed inlet deformation, and reduced airtightness, affecting combustion efficiency and furnace performance. Furthermore, unstable internal pressure can also impact the incinerator's environmental friendliness and safety. Ordinary feed inlets are easily deformed by the high temperatures in the furnace, reducing their airlock capacity. For specific types of waste, the combustion atmosphere needs to be adjusted, but mechanized addition of reagents is difficult to achieve in small incinerators. Summary of the Invention

[0017] As a further improvement and optimization of this solution, an eaves plate is provided below the bottom edge of the discharge end of the material guide section, and an air distribution groove is formed between the eaves plate and the discharge end of the material guide section.

[0018] The furnace body is equipped with an air guide tube, which is horizontally positioned. The air outlet of the air guide tube is connected to the air distribution groove, and the air inlet is connected to an air supply system. The air supply system is used to blow air into the furnace chamber to maintain negative pressure inside the furnace chamber.

[0019] The furnace body is also equipped with a dosing system, which is connected to the air guide tube and is used to add chemicals into the air guide tube so that the chemicals follow the air out of the air distribution groove and mix with the garbage discharged from the discharge end of the material guide section, thereby adjusting the atmosphere for garbage combustion.

[0020] As a further improvement and optimization of this solution, the dosing system includes:

[0021] A dosing cartridge, one end of which is connected to the side wall of the air delivery cylinder;

[0022] A dosing tank, wherein the dosing tank stores the reagent, and the bottom of the dosing tank is connected to the top side wall of the dosing cylinder;

[0023] A conveying auger is coaxially rotatable inside the dosing cylinder;

[0035] The positive effects of the above technical solution compared with the existing technology are:

[0036] (1) This utility model achieves high air-locking capability of the feeding mechanism through the combined action of the main seal of the feeding door and the auxiliary seal of the guide door, ensuring that the air tightness of the furnace is not affected by the pressure fluctuation of the furnace. At the same time, the high temperature flue gas in the furnace is effectively isolated by the insulation door, reducing the heat load on the guide door, while the feeding door hardly bears any heat load, thus avoiding the deformation problem caused by high temperature and thermal shock.

[0037] (2) By making the feeding shaft and the guiding shaft vertically distributed on the horizontal plane, this utility model effectively ensures that the garbage is constrained in multiple directions when passing through the feeding gate and the guiding gate, reducing the possibility of sticky substances entering the dead zone of the channel and adhering to the wall and corners, and improving the smoothness and efficiency of garbage disposal.

[0038] (3) In this utility model, by setting the eaves and air distribution groove at the bottom edge of the discharge end of the material guide section, the garbage can be promoted to slide down. At the same time, the airflow released by the air distribution groove forms an air cushion effect, which not only accelerates the falling process of the garbage, but also promotes the dispersion of the garbage, thereby forming a uniform and loose garbage pile in the furnace and optimizing the incineration effect.

[0039] (4) This utility model can accurately control the angle through which the stepper motor rotates by the control system, thereby accurately adjusting the conveying amount of the conveying auger, that is, the amount of medicine supplied each time, realizing the precise control of the amount of medicine supplied without manual intervention, improving the degree of automation and the accuracy of medicine use in the waste treatment process.

[0040] (5) In this utility model, the agent is fully contacted and evenly mixed with the garbage by the airflow, without the need for manual mixing. This not only reduces the labor intensity of the staff, but also significantly improves the effect of agent mixing, thus achieving high efficiency and convenience in garbage treatment.

Figure 1-12 The diagram illustrates a preferred embodiment of a feeding device for a small waste incinerator, comprising a feeding channel 1, a feeding gate 3, a guide gate 20, an insulating door 7, a drive mechanism, and an automatic control mechanism. The feeding channel 1 is mounted on the furnace body 2, with its discharge end connected to the furnace chamber 21. The feeding gate 3, guide gate 20, and insulating door 7 are sequentially rotatably arranged within the feeding channel 1 from top to bottom and are engaged with the feeding channel 1 in a sealing manner. The drive mechanism is drivenly connected to the feeding gate 3 and guide gate 20, and is used to drive the feeding gate 3 and insulating door 7 to rotate synchronously, so that the feeding gate 3 and insulating door 7 open or close the feeding channel 1 synchronously. The automatic control mechanism is drivenly connected to the guide gate 20, and the automatic control mechanism can rotate the guide gate 20 to open or close according to the weight of the material borne on the guide gate 20.

[0058] In this embodiment, the main seal of the feed gate 3 and the auxiliary seal of the guide gate 20 work together to achieve a high air-locking capability of the feed mechanism, ensuring that the airtightness of the furnace is not affected by the pressure fluctuation of the furnace chamber 21. At the same time, the high-temperature flue gas in the furnace chamber 21 is effectively isolated by the insulation door 7, reducing the heat load on the guide gate 20, while the feed gate 3 hardly bears any heat load, thereby avoiding deformation problems caused by high temperature and thermal shock.

[0059] Furthermore, in a preferred embodiment, the feed gate 3 is rotatably mounted on the feed channel 1 via the feed shaft 31; the guide gate 20 is rotatably mounted on the feed channel 1 via the guide shaft 30, and the guide shaft 30 and the feed shaft 31 are vertically distributed along the horizontal plane, and the automatic control mechanism is drivenly connected to the guide shaft 30; the insulation door 7 is rotatably mounted on the feed channel 1 via the heat insulation shaft 71, and the drive mechanism is drivenly connected to the feed shaft and the heat insulation shaft 71 respectively.

[0060] In this embodiment, by making the feed shaft 31 and the guide shaft 30 vertically distributed on the horizontal plane, it is effectively ensured that the waste is constrained in multiple directions when passing through the feed gate 3 and the guide gate 20, reducing the possibility of sticky substances entering the dead zone of the channel and adhering to the wall and corners, thus improving the smoothness and efficiency of waste treatment.

[0061] Of course, in some embodiments, the feed shaft 31 and the guide shaft 30 may also be arranged in parallel.

[0062] Furthermore, in a preferred embodiment, the feeding channel 1 includes a vertically distributed feeding section 11 and an inclinedly distributed guiding section 12. The feeding gate 3 is rotatably installed in the feeding end of the feeding section 11. The guiding section 12 is installed on the furnace body 2, and the feeding end of the guiding section 12 is connected to the discharge end of the feeding section 11, and the discharge end is connected to the furnace chamber 21. The guiding gate 20 is rotatably connected at the connection between the feeding section 11 and the guiding section 12, and the insulating door 7 is rotatably connected in the guiding section 12.

[0063] In another embodiment, the installation positions of the feed gate 3 and the guide gate 20 can be interchanged.

[0064] Furthermore, as a preferred embodiment, an eaves plate 50 is provided below the bottom edge of the discharge end of the guide section 12, and an air distribution groove 501 is formed between the eaves plate 50 and the discharge end of the guide section 12.

[0065] The furnace body 2 is equipped with an air guide cylinder 40, which is set horizontally. The air outlet of the air guide cylinder 40 is connected to the air distribution groove 501, and the air inlet is connected to an air supply system 6. The air supply system 6 is used to blow air into the furnace to maintain the negative pressure in the furnace.

[0066] In some cases, for example, the amount of harmful pollutants generated by incinerating a lot of waste in an acidic environment is two orders of magnitude higher than that generated by incinerating it in an alkaline environment. It is necessary to adjust the atmosphere of the waste during combustion in the furnace 21 by adding agent 54. However, directly adding agent 54 into the furnace is not effective. Generally, alkaline substances are mixed into the waste before it enters the furnace and stirred evenly. However, this method is very labor-intensive for small incineration plants that are difficult to mechanize, and it is also difficult to mix agent 54 evenly with waste. To solve the above problems, a dosing system 5 is also installed on the furnace body 2. The dosing system 5 is connected to the air guide tube 40 and is used to add agent 54 into the air guide tube 40 so that agent 54 follows the air out of the air distribution groove 501 and mixes with the waste discharged from the discharge end of the material guide section 12, thereby adjusting the atmosphere of waste combustion.

[0067] In this embodiment, by setting an eaves plate 50 and an air distribution groove 501 at the bottom edge of the discharge end of the material guide section 12, the garbage can be facilitated to slide down. At the same time, the airflow released by the air distribution groove 501 forms an air cushion effect, which not only accelerates the falling process of the garbage, but also promotes the dispersion of the garbage, thereby forming a uniform and loose garbage pile in the furnace 21 and optimizing the incineration effect.

[0068] Furthermore, in a preferred embodiment, the dosing system 5 includes a dosing cylinder 56, a dosing tank 52, a conveying auger 57, and a driving component. One end of the dosing cylinder 56 is connected to the side wall of the air guide cylinder 40. The dosing tank 52 stores the agent 54. The bottom of the dosing tank 52 is connected to the top side wall of the dosing cylinder 56. The conveying auger 57 is coaxially rotatably disposed inside the dosing cylinder 56. The driving component is connected to the conveying auger 57 for driving the conveying auger 57 to rotate so that the agent 54 is conveyed into the air guide cylinder 40.

[0069] Even better, the top of the dosing tank 52 is also connected to a dosing hopper 51. A pull-out door 53 is provided at the connection between the dosing hopper 51 and the dosing tank 52 to control the connection or disconnection between the dosing hopper 51 and the dosing tank 52. When it is necessary to add medicine 54 to the dosing tank 52, the pull-out door 53 can be pulled out, and the medicine 54 can be poured into the interior of the dosing tank 52 through the dosing hopper 51. Then the pull-out door 53 can be closed.

[0070] This embodiment can precisely control the angle through which the stepper motor 55 rotates by the control system, thereby accurately adjusting the conveying amount of the conveying auger 57, that is, the amount of medicine supplied each time, realizing precise control of the amount of medicine supplied without manual intervention, improving the degree of automation in the waste treatment process and the accuracy of the use of medicine 54.

[0071] In this embodiment, the airflow allows the agent 54 to fully contact and be evenly mixed with the waste, eliminating the need for manual mixing. This reduces the labor intensity of workers and significantly improves the mixing effect of the agent 54, achieving efficient and convenient waste treatment.

[0072] Furthermore, as a preferred embodiment, the driving component is a stepper motor 55 mounted on the dosing cylinder 56, and the output end of the stepper motor 55 is connected to the driving end of the conveying auger 57.

[0073] Furthermore, in a preferred embodiment, the air inlet of the air guide 40 has a nozzle 401, which is funnel-shaped. The air supply system 6 is connected to the air inlet of the nozzle 401. When the airflow passes through the nozzle 401, the static pressure decreases and the dynamic pressure increases, that is, the flow rate accelerates. In a preferred embodiment, the air supply system 6 can be an air pump.

[0074] Furthermore, in a preferred embodiment, the drive mechanism includes a drive assembly 8 and a transmission assembly 9. The drive assembly 8 is connected to one end of the feed shaft 31 for driving the feed shaft 31 to rotate. The transmission assembly 9 is connected between the feed shaft 31 and the heat insulation shaft 71, and the feed shaft 31 and the heat insulation shaft 71 rotate synchronously through the transmission assembly 9.

[0075] Even better, the drive component 8 can be a motor, and the transmission component 9 can be a belt drive, chain drive, etc.

[0076] In another embodiment, the drive assembly 8 may also be a hydraulic cylinder / pneumatic cylinder / electric cylinder. A rocker arm is provided between the hydraulic cylinder / pneumatic cylinder / electric cylinder and the feed shaft 31. One end of the hydraulic cylinder / pneumatic cylinder / electric cylinder is hinged to the outer wall of the feed channel 1, and the other end is hinged to one end of the rocker arm. The other end of the rocker arm is connected to one end of the feed shaft 31. The feed shaft 31 is driven to rotate by the extension and retraction of the output end of the hydraulic cylinder / pneumatic cylinder / electric cylinder.

[0077] Furthermore, as a preferred embodiment, the guide door 20 has a double-door structure, which includes two door bodies 201, which are arranged opposite to each other and located on both sides of the feeding channel 1; the guide shaft 30 includes two rotating shafts 301, and each door body 201 is rotatably installed in the feeding channel 1 through a rotating shaft 301.

[0078] Furthermore, as a preferred embodiment, the automatic control mechanism includes: two counterweight arms 10, one end of each counterweight arm 10 being connected to one end of two rotating shafts 301 and the other end being connected to a counterweight block 101, and the counterweight arms 10 being perpendicular to the rotating shafts 301.

[0079] Furthermore, as a preferred embodiment, a sealing structure 4 is provided between the feed gate 3 and the feed channel 1, and between the guide gate 20 and the feed channel 1. When the feed gate 3 / guide gate 20 is in the closed state, the feed gate 3 / guide gate 20 is sealed and blocked from the feed channel 1 by the sealing structure 4.

[0080] Each sealing structure 4 includes a door cover 41 coaxially distributed with the feeding channel 1. The door cover 41 is shaped like a bucket, which can effectively constrain the garbage to flow in the center of the garbage channel of the feeding mechanism, and prevent the garbage from being caught by the feeding shaft 31 and the guide shaft 30 and stuck inside the feeding channel 1. Each door cover 41 has a sealing element 42 at the bottom. The sealing element 42 is arranged around the bottom opening of the door cover 41 and is used to seal with the guide door 20 / feeding door 3 to improve the sealing effect of the feeding door 3 and the guide door 20, thereby improving the air-locking performance of the feeding structure. In some embodiments, the sealing element 42 can be a rubber gasket.

[0081] This embodiment also relates to a feeding method using the above-described feeding mechanism for a small waste incinerator, comprising:

[0082] S1: When it is necessary to feed waste into the incinerator, start the drive mechanism and open the feed door 3 and the insulation door 7 simultaneously;

[0083] S2: The waste enters through the feeding section 11 of the feeding channel 1. When the waste falls to the guiding section 12, it will come into contact with the guiding gate 20. Under the action of the impact momentum and its own weight, the guiding gate 20 will rotate against the gravity of the counterweight block 101 and open the guiding gate 20. The waste slides down the guiding section 12 into the furnace 21. At the same time, the chemical dosing system 5 mixes the chemical agent 54 into the waste in the guiding section 12.

[0084] S3: After all the waste is discharged from the guide section 12 and enters the furnace 21, the guide door 20 is reset and closed under the action of the counterweight 101. At the same time, under the action of the drive mechanism, the feed door 3 and the insulation door 7 are closed synchronously, completing the feeding process.

[0085] In step S2, when a chemical mixing operation is required:

[0086] S21: Ensure that the dosing tank 52 contains sufficient reagent 54;

[0087] S22: Connect the air supply system 6 and the airflow enters the air guide tube 40 from the nozzle 401;

[0088] S23: Start the stepper motor 55 and drive the conveying auger 57 to rotate, so that the agent 54 in the dosing tank 52 is conveyed to the air guide cylinder 40 through the conveying auger 57, and the amount of agent supplied is precisely controlled by controlling the rotation angle of the stepper motor 55.

[0089] S24: The airflow from the air supply system 6 is accelerated by the nozzle 401 and blown toward the agent 54, while the agent 54 is sprayed out from the air distribution groove 501 under the action of the air.

[0090] S24: The airflow carrying agent 54 comes into full contact with the garbage that is about to leave the guide section 12 and begin to fall, and allows agent 54 to adhere to the garbage, thereby achieving uniform mixing of garbage and agent 54 to regulate the incineration atmosphere.

[0091] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
