Description

Technical Field

[0001] This utility model relates to the field of steam generator technology, specifically to an automatic feeding device for a biomass industrial steam generator. Background Technology

[0002] Biomass energy, as a clean and renewable energy source, has been increasingly widely used in the industrial field. Biomass industrial steam generators produce steam by burning biomass fuel, providing thermal energy support for many industries such as food processing, textile printing and dyeing, and papermaking. However, automatic feeding equipment is required in the process of feeding biomass industrial steam generators. However, the existing automatic feeding equipment for biomass industrial steam generators still has certain defects in use. For example, the biomass pellet feeding mechanism for a biomass steam generator proposed in application number CN202122531195.0 includes a furnace chamber, a hopper, and a feeding cylinder. When feeding is required into the furnace chamber, a telescopic push rod is used to push the feeding screw into the furnace chamber. At this time, the feeding screw pushes the sealing plate, the isolation frame, and the heat insulation plate into the furnace chamber. The drive motor drives the feeding screw to rotate through the transmission shaft and the drive gear plate, thereby pushing the biomass fuel in the feeding cylinder into the furnace chamber to achieve feeding. In actual use, when biomass pellets are stored inside the hopper and fed through the bottom feeding cylinder, the biomass pellets accumulated inside the hopper will cause accumulation and blockage, which will affect the efficiency of biomass pellets entering the feeding cylinder. At the same time, the inlet positions of different specifications of biomass steam generators are different, and the biomass pellet feeding mechanism of this biomass steam generator cannot adjust its own height, so it can only be connected and adapted to biomass steam generators of specific specifications, which reduces its practicality.

[0003] Therefore, we propose an automatic feeding device for biomass industrial steam generators to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide an automatic feeding device for biomass industrial steam generators, in order to solve the problems mentioned in the background art, such as the accumulation and blockage of biomass pellets and the inconvenience of adapting to biomass steam generators with different feeding heights.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for a biomass industrial steam generator, comprising a storage bin, a support frame fixedly installed on the outer ring of the storage bin, a conveying pipe fixedly connected to the bottom inner side of the support frame, a discharge bin fixedly connected to the top of the conveying pipe, the outer ring of the discharge bin being fixedly connected to the support frame, an auger shaft rotatably installed inside the conveying pipe, a drive motor connected to the front end of the auger shaft, positioning frames fixedly installed on both sides of the drive motor, and the positioning frames being fixedly connected to the front end of the conveying pipe; An anti-clogging mechanism is installed at the front end of the auger shaft and inside the discharge hopper to prevent accumulation and blockage. The bottom end of the support frame is fixedly connected to a base plate.

[0006] Preferably, the anti-clogging mechanism includes a driving bevel gear fixedly sleeved on the front end of the auger shaft, a driven bevel gear meshing with the top of the driving bevel gear, a transmission rod fixedly installed on the top surface of the driven bevel gear, a support seat rotatably sleeved on the outer ring of the transmission rod, and the rear end of the support seat fixedly connected to the outer ring of the discharge hopper.

[0007] Preferably, the anti-clogging mechanism further includes a drive gear fixedly installed at the top of the transmission rod. The rear side of the drive gear is meshed with a toothed ring. The upper and lower ends of the toothed ring are rotatably connected to the storage bin and the discharge bin, respectively. A connecting rod is fixedly installed at equal angles on the inner ring of the toothed ring, and a scraper is fixedly installed at the bottom end of the connecting rod.

[0008] Preferably, the driving bevel gear and the driven bevel gear are perpendicularly meshed, the drive gear is parallelly meshed with the gear ring, and the bottom surface of the scraper is in close contact with the inner wall of the discharge bin.

[0009] The above-mentioned structural design, through the mechanical transmission consisting of an active bevel gear, a driven bevel gear, a transmission rod, a drive gear, and a gear ring, combined with the close fit between the scraper and the inner wall of the discharge bin, can effectively break up the accumulated clumps of biomass fuel when the scraper rotates, improving the smoothness of feeding and the anti-clogging effect.

[0010] Preferably, the bottom of the base plate is connected to a height adjustment mechanism; The height adjustment mechanism includes fixed bearing seats symmetrically installed on the bottom surfaces of both ends of the base plate. A movable support plate is rotatably connected inside the fixed bearing seat. A sliding bearing seat is rotatably installed at the bottom of the movable support plate. A base is sleeved on the left and right sides of the sliding bearing seats. Sliding grooves are opened at both ends of the base. Adjustment screws are rotatably installed at both ends of the base.

[0011] Preferably, the sliding bearing seats on the left and right sides are slidably connected to the base through the sliding grooves on the left and right sides, and the adjusting screws on the left and right sides are threadedly connected to the sliding bearing seats on the left and right sides, with the threads at both ends of the adjusting screws opening in opposite directions.

[0012] The above-mentioned structural design allows for the lateral movement of the sliding shaft seat by adjusting the screw, while the movable support plate rotates around the fixed shaft seat to form a lifting structure. This enables the adjustment of the overall height of the equipment, which in turn facilitates the adaptation to the inlet height of steam generators of different specifications. This avoids installation and adaptation problems caused by the fixed height of the equipment and improves the practicality of the automatic feeding equipment for biomass industrial steam generators.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the automatic feeding equipment for the biomass industrial steam generator; 1. Through the vertical meshing transmission of the active bevel gear and the driven bevel gear, the power of the auger shaft is synchronized to the transmission rod. The parallel meshing structure of the drive gear and the gear ring further drives the scraper to make a circular motion on the inner wall of the discharge bin. This allows the scraper to effectively break up the accumulation and clumping problem of biomass fuel caused by irregular shape or high humidity. It helps to avoid the arch-shaped accumulation and blockage phenomenon common in traditional equipment, so that the fuel falls evenly into the conveying pipe and improves the anti-clogging effect and feeding smoothness of the automatic feeding equipment for biomass industrial steam generator. 2. Based on the reverse drive design of the trapezoidal thread adjusting screw, the left and right sliding shaft seats move synchronously through the sliding groove limit, and the movable support plate forms a four-bar lifting structure, which can adjust the height of the equipment within the range. This is beneficial for adapting to the feed inlet height of biomass industrial steam generators of different specifications, which helps to improve the feeding adaptability and practicality of the automatic feeding equipment for biomass industrial steam generators. Furthermore, the screw self-locking and sliding groove limit double protection ensure the stability of the equipment during operation, significantly improving installation efficiency and usage safety.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please refer to Figures 1-3 This utility model provides a technical solution: an automatic feeding device for a biomass industrial steam generator, including a storage bin 1, a support frame 2 fixedly installed on the outer ring of the storage bin 1, a bottom plate 16 fixedly connected to the bottom end of the support frame 2, a conveying pipe 4 fixedly connected to the bottom inner side of the support frame 2, a discharge bin 3 fixedly connected to the top of the conveying pipe 4, the outer ring of the discharge bin 3 fixedly connected to the support frame 2, an auger shaft 5 rotatably installed inside the conveying pipe 4, a drive motor 6 connected to the front end of the auger shaft 5, positioning frames 7 fixedly installed on both sides of the drive motor 6, and the positioning frames 7 fixedly connected to the front end of the conveying pipe 4; In the above-described structure, the storage bin 1 is used to store biomass fuel. The fuel falls to the discharge bin 3 at the bottom by its own gravity, and the discharge bin 3 is connected to the top of the conveying pipe 4 to form a channel for the fuel to enter the conveying pipe 4. The drive motor 6 generates rotational power after being powered on, and is fixed to the front end of the conveying pipe 4 by the positioning frame 7 to ensure the stability of power transmission. The output shaft of the drive motor 6 is directly connected to the auger shaft 5, which drives the auger shaft 5 to rotate inside the conveying pipe 4. When the auger shaft 5 rotates, the spiral blades on its outer periphery generate axial thrust, which transports the fuel falling from the discharge bin 3 along the conveying pipe 4 axially, ensuring that the fuel does not slip or get blocked during the transportation process, and moves evenly towards the feed port of the steam generator, thereby completing the feeding process of biomass pellet fuel. The support frame 2 on the outer ring of the storage bin 1 provides structural support for the equipment, and its bottom end is fixedly connected to the bottom plate 16 to form a stable vertical frame structure.

[0018] An anti-clogging mechanism is installed at the front end of the auger shaft 5 and inside the discharge bin 3 to prevent accumulation and blockage. The anti-clogging mechanism includes a drive bevel gear 8 fixedly sleeved at the front end of the auger shaft 5. A driven bevel gear 9 is meshed with the top of the drive bevel gear 8. The drive bevel gear 8 and the driven bevel gear 9 are meshed vertically. A transmission rod 10 is fixedly installed on the top surface of the driven bevel gear 9. A support seat 11 is rotatably sleeved on the outer ring of the transmission rod 10. The rear end of the support seat 11 is fixedly connected to the outer ring of the discharge bin 3. The anti-clogging mechanism also includes a drive gear 12 fixedly installed at the top end of the transmission rod 10. A toothed ring 13 is meshed with the rear side of the drive gear 12. The drive gear 12 and the toothed ring 13 are meshed in parallel. The upper and lower ends of the toothed ring 13 are rotatably connected to the storage bin 1 and the discharge bin 3, respectively. A connecting rod 14 is fixedly installed at equal angles on the inner ring of the toothed ring 13. A scraper 15 is fixedly installed at the bottom end of the connecting rod 14. The bottom surface of the scraper 15 is tightly fitted to the inner wall of the discharge bin 3. In the above-described structure, when the drive motor 6 drives the auger shaft 5 to rotate and transport fuel, the active bevel gear 8 fixed at the front end of the auger shaft 5 rotates synchronously. Through the vertically meshing driven bevel gear 9, the horizontal rotational power is converted into the vertical rotational power of the transmission rod 10. The drive gear 12 at the top of the transmission rod 10 rotates accordingly, forming a transmission structure with the parallel meshing gear ring 13. This amplifies the torque and drives the gear ring 13 to make a circular motion. The connecting rod 14 of the inner ring of the gear ring 13 drives the scraper 15 to rotate synchronously against the inner wall of the discharge bin 3, continuously scraping and breaking up the blockage formed by fuel accumulation. This allows the fuel to fall evenly into the conveying pipe 4 under the action of gravity, which works in conjunction with the spiral conveying action of the auger shaft 5 to achieve continuous and stable feeding of biomass fuel.

[0019] Example 2: Based on Example 1, this utility model adopts the following... Figures 4-5 The technical solution shown further discloses that the bottom of the base plate 16 is connected to a height adjustment mechanism. The height adjustment mechanism includes fixed shaft seats 17 symmetrically installed on the bottom surfaces of both ends of the base plate 16. A movable support plate 18 is rotatably connected inside the fixed shaft seat 17. A sliding shaft seat 19 is rotatably installed at the bottom of the movable support plate 18. A base 20 is respectively fitted on the left and right sliding shaft seats 19. Slide grooves 21 are opened at both ends of the base 20. The left and right sliding shaft seats 19 are slidably connected to the base 20 through the slide grooves 21. Adjusting screws 22 are rotatably installed at both ends of the base 20. The left and right adjusting screws 22 are threadedly connected to the left and right sliding shaft seats 19. The threads at both ends of the adjusting screws 22 are reversed. The above-described structure allows for the adjustment of equipment height by rotating the adjusting screw 22. The reverse threads at both ends of the screw cause the sliding bearings 19 on both sides to move synchronously in opposite directions along the grooves 21 of the base 20. When the sliding bearings 19 move towards the center, the movable support plate 18 rotates upward around the fixed bearing 17, pushing the base plate 16 upward. Conversely, when the sliding bearings 19 move away from both ends, the movable support plate 18 rotates downward, causing the base plate 16 to descend. Throughout this process, the grooves 21 provide horizontal guidance and vertical limitation for the sliding bearings 19, ensuring stable movement. The high-strength movable support plate 18 and the symmetrical double-support structure together bear the weight of the equipment, forming a stable support that is suitable for adapting to the inlet height of steam generators of different specifications.
