Description

Technical Field

[0001] This utility model relates to the field of incineration equipment, and in particular to a feeding device for an incinerator. Background Technology

[0002] Incinerators, as key equipment for treating municipal solid waste, medical waste, industrial solid waste, and hazardous waste, rely on high-temperature incineration to achieve the harmlessness, reduction, and resource recovery of waste. Maintaining a stable high-temperature environment and negative pressure within the furnace is crucial. This not only affects incineration efficiency and the effective decomposition of pollutants but is also a fundamental requirement to prevent the escape of unburned harmful gases, dust, and odors into the operating environment, ensuring the health of personnel and the safety of the surrounding environment. Traditional incinerator feeding systems often employ a single-door design. During the feeding process, when the feeding door is opened, the high-temperature gases inside the furnace will rapidly leak out due to negative pressure or thermal expansion, leading to energy loss, a sudden drop in furnace temperature that disrupts incineration conditions, and the risk of toxic and harmful substances escaping. Simultaneously, a large amount of cold air from outside enters the furnace, diluting the combustion atmosphere, increasing combustion energy consumption, and potentially disrupting airflow organization, creating low-temperature zones, exacerbating incomplete combustion, and increasing the risk of pollutant generation. Furthermore, frequent opening of the single door causes severe thermal shock to the door body and surrounding refractory materials, shortening the equipment's lifespan. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the present invention provides a feeding device for an incinerator, which solves the problems of reduced internal temperature of the combustion furnace and leakage of harmful gases when the single door is opened in the existing technology.

[0004] According to an embodiment of this utility model, a feeding device for an incinerator is provided. The feeding device is disposed at the inlet of the incinerator and includes an isolation chamber, a front baffle, a rear baffle, a pushing assembly, and a driving assembly. One end of the isolation chamber is connected to the inlet of the incinerator, and the other end of the isolation chamber away from the incinerator is open. The top surface of the front baffle is rotatably connected to the top of the end of the isolation chamber away from the incinerator, and the size of the front baffle is adapted to the opening of the isolation chamber. The rear baffle is slidably connected to the side wall of the incinerator in the vertical direction and is used to close or open the inlet. The driving assembly is used to drive the front baffle to rotate or the rear baffle to slide. The pushing assembly is disposed on the front baffle and is used to push the material in the isolation chamber into the incinerator.

[0005] The technical principle of this utility model is as follows: This device forms an airtight isolation chamber by alternately opening and closing the front baffle and the rear baffle. The drive component controls the linkage between the two to realize staged feeding. The push component is used to send the material into the furnace, avoiding direct connection between the inside and outside of the incinerator.

[0006] Preferably, the drive assembly includes a drive shaft, a first gear, a second gear, a third gear, and a power unit. The first gear is fixedly mounted on the end of the rotating shaft of the front baffle, and the side of the rear baffle is provided with strip teeth in the vertical direction. The drive shaft is horizontally mounted on the top of the outer side of the isolation chamber and rotatably connected to the isolation chamber. The second gear and the third gear are respectively fixed at both ends of the drive shaft. The first gear and the second gear are bevel gears and mesh with each other. The third gear meshes with the strip teeth. The drive shaft is composed of two coaxial and separate shaft segments, with a gap between the two shaft segments. The power unit is located at the gap and is used to drive the two ends of the drive shaft to rotate respectively.

[0007] Preferably, the power unit includes a movable shaft, a motor, a fourth gear, a fifth gear, and an adjustment mechanism. The movable shaft and the transmission shaft are coaxial and located at the interval. The length of the movable shaft is less than the distance of the interval. The movable shaft is rotatably connected to the outside of the isolation chamber. Both ends of the transmission shaft are provided with blind holes. The opening position of the blind holes is provided with an inlet angle. The sidewall of the blind holes is provided with a keyway along the axial direction. Both ends of the movable shaft are adapted to the blind holes. The end of the movable shaft is fixedly provided with a positioning key adapted to the keyway. The fourth gear is fixedly connected to the movable shaft. The motor is fixedly connected to the incinerator. The fifth gear is fixedly mounted on the output shaft of the motor. The fourth gear meshes with the fifth gear. The adjustment mechanism is used to control the axial movement of the movable shaft.

[0008] Preferably, the adjusting mechanism includes a first telescopic rod and a connecting plate, the connecting plate and the movable shaft are fixedly connected, the first telescopic rod and the movable shaft are parallel, the fixed end of the first telescopic rod is fixedly connected to the isolation chamber, the side of the connecting plate is provided with an annular T-groove, and the movable end of the first telescopic rod is provided with a T-joint that slides with the T-groove.

[0009] Preferably, the pushing assembly includes a second telescopic rod and a push plate. The push plate is vertically disposed on the side of the front baffle near the incinerator. The fixed end of the second telescopic rod is fixedly disposed on the other side of the front baffle. The movable section of the second telescopic rod passes through the front baffle and is fixedly connected to the middle of the push plate.

[0010] Preferably, the isolation chamber has a rectangular structure, the bottom surface of the isolation chamber is inclined, and the side closer to the incinerator faces downward.

[0011] Preferably, the drive components are symmetrically arranged on the left and right sides of the isolation chamber.

[0012] Preferably, a latch is provided between the isolation compartment and the front baffle.

[0013] Preferably, the side of the rear baffle facing the incinerator is provided with a heat insulation layer.

[0014] Compared to existing technologies, this invention offers the following advantages: The incinerator feeding device, through the coordinated design of the front and rear baffles, significantly improves the safety, controllability, and environmental friendliness of the feeding process. The front baffle, acting as the first barrier, uses a top-rotating connection. It opens outwards during feeding to form a material inlet and closes immediately after feeding, effectively preventing direct contact between the high-temperature flue gas inside the incinerator and the external environment, reducing heat loss and the risk of toxic gas spillage. Its dimensions are precisely matched to the opening of the isolation chamber, ensuring airtightness and preventing dust diffusion. The rear baffle controls the opening and closing of the feed inlet through vertical sliding, forming a linkage mechanism with the front baffle. After the front baffle closes, the rear baffle opens, pushing the component to feed material into the incinerator, and then the rear baffle quickly closes. This phased operation mode further extends the sealing time of the incinerator, preventing high-temperature airflow from backflowing into the isolation chamber and protecting the equipment from thermal stress damage. The dual isolation effect of the double-baffle structure maintains a negative pressure state inside the incineration system, improving thermal efficiency and significantly reducing air pollution in the operating area. In addition, the independent drive design of the front and rear baffles reduces wear on individual components and extends the equipment maintenance cycle. Combined with precise automated control, it enables flexible adjustment of the feed rate and rhythm to adapt to different working conditions. Attached Figure Description

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 As shown in the figure, this utility model embodiment proposes a feeding device for an incinerator. The feeding device is located at the feed inlet of the incinerator 1. The device includes an isolation chamber 3, a front baffle 5, a rear baffle 2, a pushing assembly, and a driving assembly. One end of the isolation chamber 3 is connected to the feed inlet of the incinerator 1, and the other end of the isolation chamber 3 away from the incinerator 1 is open. After the material enters the isolation chamber 3, it enters the incinerator 1. The top surface of the front baffle 5 is rotatably connected to the top of the end of the isolation chamber 3 away from the incinerator 1. The size of the front baffle 5 is adapted to the opening of the isolation chamber 3. When the front baffle 5 rotates upward, the opening of the isolation chamber 3 is open. When the front baffle 5 rotates downward, it can close the opening of the isolation chamber 3 to prevent gas from escaping from the isolation chamber 3. The rear baffle 2 is slidably connected to the side wall of the incinerator 1 in the vertical direction. The rear baffle 2 is used to close or open the feed inlet. In this embodiment, a sliding cover is fixedly installed on the side wall of the isolation chamber 3, and the rear baffle 2 slides along the vertical direction of the sliding cover. One end of the isolation chamber 3 is connected to the lower side wall of the sliding cover. The driving component is used to drive the front baffle 5 to rotate or the rear baffle 2 to slide. The isolation chamber 3 and the front baffle 5 prevent the incinerator 1 from being directly connected to the outside. The driving component makes the two ends of the isolation chamber 3, the front baffle 5 and the rear baffle 2, in different states, thereby completing the feeding. The pushing component is installed on the front baffle 5 and is used to push the material in the isolation chamber 3 into the incinerator 1. After the material is put into the isolation chamber 3, the pushing component works, avoiding the need for manual labor to complete the final step of feeding into the incinerator 1.

[0023] like Figure 2As shown, preferably, the drive assembly includes a drive shaft 11, a first gear 9, a second gear 10, a third gear 22, and a power unit. The first gear 9 is fixedly mounted at the end of the rotating shaft 8 of the front baffle 5, and the side of the rear baffle 2 is provided with strip teeth in the vertical direction. The drive shaft 11 is horizontally mounted on the top of the outer side of the isolation chamber 3 and rotatably connected to the isolation chamber 3. The second gear 10 and the third gear 22 are respectively fixed at both ends of the drive shaft 11. The first gear 9 and the second gear 10 are bevel gears and mesh with each other, and the third gear 22 meshes with the strip teeth. The drive shaft 11 is composed of two coaxially separated shaft segments, with a gap between the two shaft segments. The power unit is located at the gap and is used to drive the two ends of the drive shaft 11 to rotate respectively. In this embodiment, a through hole is provided on the side wall of the sliding cover for the third gear 22 to enter the interior of the sliding cover and mesh with the strip teeth. The width of the rear baffle 2 is greater than the size of the incinerator 5. The rear baffle 2 has a sandwich structure with a heat insulation layer in the middle. The strip teeth are located in the sandwich of the rear baffle 2 away from the incinerator 5. The drive assembly achieves efficient and stable power transmission and independent and precise drive of the front and rear baffles 2 through a compact and flexible gear transmission and segmented drive shaft 11 design, which is convenient for maintenance and upgrades and has strong adaptability.

[0024] like Figure 2 , 3As shown in Figure 4, preferably, the power unit includes a movable shaft 15, a motor 18, a fourth gear 16, a fifth gear 17, and an adjustment mechanism. The movable shaft 15 and the transmission shaft 11 are coaxial and located at the interval. The length of the movable shaft 15 is less than the distance of the interval, so that the movable shaft 15 can only be connected to one end of the transmission shaft 11. The movable shaft 15 is rotatably connected to the outside of the isolation chamber 3. A connecting block 12 is fixedly provided on the outside of the isolation chamber 3 for rotatably connecting with the movable shaft 15. Both disconnected ends of the transmission shaft 11 are provided with connecting blind holes 13. The opening position of the connecting blind holes 13 is provided with an inlet angle 21, which facilitates the insertion of the end of the movable shaft 15 into the connecting blind holes 13. The sidewall of the connecting blind holes 13 is provided with a keyway 25 along the axial direction. Both ends of the movable shaft 15 are adapted to the connecting blind holes 13. The end of the movable shaft 15 is fixedly provided with a positioning key 14 adapted to the keyway 25. When one end of the movable shaft 15 is inserted into the connecting blind hole 13, the positioning key 14 also enters the keyway 25, making the movable shaft 15 and the transmission shaft 11 radially fixed, thus enabling the movable shaft 15 and the transmission shaft 11 to rotate synchronously. The fourth gear 16 is fixedly connected to the movable shaft 15, the motor 18 is fixedly connected to the incinerator 1, and the fifth gear 17 is fixedly mounted on the output shaft of the motor 18, with the fourth gear 16 meshing with the fifth gear 17. The adjusting mechanism is used to control the axial movement of the movable shaft 15. The adjusting mechanism controls the movable shaft 15 so that one end of the movable shaft 15 meshes with the corresponding shaft segment, driving the front baffle 5 or the rear baffle 2 to move respectively.

[0025] like Figure 5 As shown, preferably, the adjusting mechanism includes a first telescopic rod 20 and a connecting plate 19. The connecting plate 19 is fixedly connected to the movable shaft 15. The first telescopic rod 20 and the movable shaft 15 are parallel. The fixed end of the first telescopic rod 20 is fixedly connected to the isolation chamber 3. The side of the connecting plate 19 is provided with an annular T-slot 23. The movable end of the first telescopic rod 20 is provided with a T-joint 24 that slides with the T-slot 23. In this embodiment, the orthographic projection of the T-joint 24 on the horizontal plane is circular. The T-slot 23 and the T-joint 24 are in clearance fit. When the first telescopic rod 20 extends or retracts, it pushes the connecting plate 19 to move along the axis of the movable shaft 15, thereby driving the movable shaft 15 to move. In addition, to avoid rigid contact between the end of the positioning key 14 and the end of the keyway 25 when the first telescopic rod 20 extends, the movable end of the first telescopic rod 20 includes a fixed sleeve and a sliding rod. The fixed sleeve and the sliding rod are coaxial and slidably connected. A spring is provided inside the fixed sleeve, and the two ends of the spring are fixedly connected to the fixed sleeve and the sliding rod, respectively. One end of the sliding rod is fixedly connected to the T-joint 24. To facilitate the insertion of the positioning key 14 into the keyway 25, the entry end of the keyway 25 is chamfered.

[0026] Preferably, the pushing assembly includes a second telescopic rod 6 and a push plate 4. The push plate 4 is vertically disposed on the side of the front baffle 5 near the incinerator 1. The fixed end of the second telescopic rod 6 is fixedly disposed on the other side of the front baffle 5. The movable section of the second telescopic rod 6 passes through the front baffle 5 and is fixedly connected to the middle of the push plate 4. In this embodiment, a connecting rod 7 for support is provided below the fixed end of the second telescopic rod 6, making the connection between the second telescopic rod 6 and the front baffle 5 more stable. When the second telescopic rod 6 extends, the push plate 4 pushes the material in the isolation chamber 3 into the incinerator 1.

[0027] Preferably, the isolation chamber 3 has a rectangular structure, and its bottom surface is inclined, with the side closest to the incinerator 1 facing downwards. The inclined surface makes it easier for materials to slide into the incinerator 1, avoiding blockages caused by insufficient thrust of the second telescopic rod 6.

[0028] Preferably, the drive components are symmetrically arranged on the left and right sides of the isolation chamber 3. The force applied to both sides of the front baffle 5 and the rear baffle 2 makes the movement more stable.

[0029] Preferably, a latch is provided between the isolation chamber 3 and the front baffle 5. The presence of the latch provides a clear physical lock / unlock signal point for the control system. Subsequent operations, such as opening the rear baffle 2 for material feeding, are only permitted after confirming that the latch is securely locked. Conversely, the latch must be released before opening the front baffle 5, enhancing the safety and rigor of the control logic.

[0030] Preferably, the rear baffle 2 is provided with a heat insulation layer on the side facing the incinerator 1, the heat insulation layer being used to reduce heat loss within the incinerator 1. In this embodiment, the heat insulation layer is made of ceramic fiber.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
