Description

An anti-clogging feeding mechanism for a gasifier Technical Field

[0001] This utility model relates to the field of chemical technology, and in particular to an anti-clogging feeding mechanism for a gasifier. Background Technology

[0002] A biomass gasifier is a device that converts biomass materials into combustible gas. It utilizes a thermochemical reaction under high temperature and oxygen-deficient conditions. A Chinese utility model patent, authorized publication number "CN221522477U", discloses a biomass gasifier feed anti-blocking device, belonging to the field of biomass processing technology. This biomass gasifier feed anti-blocking device includes a furnace body and a dispersing anti-blocking mechanism. A feed hopper is installed on the top of the furnace body, and a rotating shaft is movably connected inside the feed hopper. A motor is fixedly connected to the left side of the top of the furnace body, and the left side of the rotating shaft is fixedly connected to the output end of the motor. Dispersing rods are fixedly connected to both sides of the rotating shaft surface, and contact balls are fixedly connected to the outer side of the dispersing rods. A translational feeding mechanism is movably connected to the four corners inside the feed hopper. By setting up the dispersing anti-blocking mechanism, the material is dispersed and prevented from blocking as it enters the furnace body through the feed hopper, ensuring that the material passes evenly through the feed hopper and enters the furnace body, thus avoiding blockage during the feed hopper's operation.

[0003] The above-mentioned technical solution, by setting up a translational material-dispersing mechanism, can use the rotational force of the contact ball to move the material at the top of the feed hopper when the dispersing rod drives the contact ball to disperse the material, thus avoiding the material from accumulating at the top of the feed hopper. However, the above-mentioned technical solution still has certain drawbacks. For example, although the above equipment uses the dispersing rod to drive the contact ball to disperse the material, thus avoiding the material from clogging during feeding, the feeding speed is sometimes fast and sometimes slow. This will affect the combustion efficiency of the gasifier, which will lead to a decrease in combustion efficiency and reduce the practicality of the equipment. Summary of the Invention

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an anti-clogging feeding mechanism for a gasifier. This mechanism can solve the problem that the equipment uses a dispersing rod to drive a contact ball to disperse the material, thus avoiding blockage during feeding. However, the feeding speed is sometimes fast and sometimes slow, which affects the combustion efficiency of the gasifier and leads to a decrease in combustion efficiency, thereby reducing the practicality of the equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an anti-clogging feeding mechanism for a gasifier, comprising a gasifier body and a mounting box, wherein an adjustment device is provided on the mounting box;

Fixing bolts 12 are threadedly connected to one end of each limit bracket 13. The ends of the two fixing bolts 12 near the fixing bolt grooves 11 extend threadedly to the outside of one end of the limit bracket 13 and are respectively threadedly connected to the internal threads of the corresponding fixing bolt grooves 11. The vibration motor 9... The feed box 8 is fixedly installed on one side of the outer wall. The lower surfaces of the two sliding seats 3 are fixedly connected to the connecting brackets 19. The two connecting brackets 19 are both "L" shaped. The outer walls of the two sides of the baffle 18 are fixedly connected to the outer walls of the opposite side of the lower end of the corresponding connecting brackets 19. The upper surfaces of the two fixed limiting seats 10 are rotatably connected to the rotating threaded rods 17. The upper surfaces of the two sliding seats 3 are provided with fixing bolts 12. The ends of the two rotating threaded rods 17 near the fixing bolts 12 are threaded into the interior of the sliding seat groove 20 and are respectively threaded into the interior of the corresponding fixing bolts 12. The baffle 18 is conical. The upper outer wall of the baffle 18 contacts the inner wall of the lower outlet of the feed box 8. The upper surfaces of the two sliding seats 3 are provided with rotating threaded rod grooves 21. The ends of the two rotating threaded rods 17 near the fixed limiting seats 10 are rotatably extended into the interior of the sliding seat groove 20 and are respectively threaded into the interior of the corresponding rotating threaded rod groove 21.

[0034] The mounting box 2 is fixedly connected to the upper surface of the gasifier body 1. The interior of the feeding box 8 is connected to the interior of the mounting box 2. One end of the mounting box 2 near the gasifier body 1 is fixedly extended into the interior of the gasifier body 1. The interior of the gasifier body 1 is connected to the interior of the mounting box 2. Inclined plates 15 are fixedly connected to both inner walls of the mounting box 2. The two inclined plates 15 are inclined inside the mounting box 2. A rotating shaft 7 is rotatably connected to the upper end of the feeding box 8. Multiple fixed mounting seats 6 are fixedly connected to the outer wall of the rotating shaft 7. The outer wall of the multiple fixed mounting seats 6 is provided with four dispersing rod grooves 14. A motor 4 is fixedly connected to one outer wall of the upper end of the feeding box 8. The output end of the motor 4 rotatably extends into the interior of the feeding box 8 and is fixedly connected to one end of the rotating shaft 7. Multiple dispersing rods 5 are provided inside the feeding box 8. The outer wall of one end of the multiple dispersing rods 5 is respectively threadedly connected to the interior of the corresponding dispersing rod groove 14.

[0035] Furthermore, when using this device, it is started by connecting to an external power source. First, the material is fed into the feed box 8. Then, the output of the motor 4 rotates, driving the rotating shaft 7 to rotate, which in turn drives multiple fixed mounting seats 6 to rotate, and simultaneously drives multiple dispersing rods 5 to disperse the material. At the same time, the force generated by the vibrating motor 9 on the feed box 8 prevents the material from adhering to the inner wall of the feed box 8. Then, the fixing bolt 12 is turned to rotate, causing its other end outer wall to disengage from the inside of the fixing bolt groove 11. Next, the rotating threaded rod 17 is turned to rotate, which in turn drives the sliding seat 3 to move downward, and simultaneously drives the connecting frame 19 to move downward. Then, the downward movement of the connecting frame 19 drives the baffle 18 to move downward. Move it downwards to adjust the gap between the upper outer wall of the baffle 18 and the discharge port of the feed box 8. After adjustment, tighten the fixing bolt 12 so that the other end of the outer wall enters the corresponding fixing bolt groove 11 for limiting. Then, control the gap between the upper end of the baffle 18 and the discharge port of the feed box 8 to control the discharge speed, effectively avoiding the discharge speed from being too fast or too slow. Then, the broken material falls into the installation box 2 and is guided by the two inclined plates 15 to fall into the gasifier body 1. Then, when it is necessary to remove the dispersing rod 5, twist the dispersing rod 5 to rotate so that the other end of the outer wall is disengaged from the inside of the dispersing rod groove 14. In this way, the dispersing rod 5 can be removed from the fixed mounting base 6.

[0036] By rotating the fixing bolt 12 in the adjusting device, the outer wall of its other end is disengaged from the inside of the fixing bolt groove 11. Then, by rotating the threaded rod 17, the sliding seat 3 is moved downwards, which in turn moves the connecting frame 19 downwards. The downward movement of the connecting frame 19 then moves the baffle 18 downwards. This controls the gap between the upper end of the baffle 18 and the discharge port of the feed box 8, thus controlling the feeding speed and effectively avoiding inconsistent feeding speeds. This improves the combustion efficiency and the practicality of the equipment. By rotating the dispersing rod 5, the outer wall of its other end is disengaged from the inside of the dispersing rod groove 14. This allows the dispersing rod 5 to be removed from the fixed mounting base 6, facilitating maintenance and repair. This improves the maintenance and repair efficiency of the dispersing rod 5 and enhances the flexibility of the equipment.

[0037] Working principle: First, the material is fed into the feed box 8. Then, the output of the motor 4 rotates, driving the rotating shaft 7 to rotate, which in turn drives multiple fixed mounting seats 6 to rotate, and simultaneously drives multiple dispersing rods 5 to disperse the material. At the same time, the force generated by the vibrating motor 9 on the feed box 8 prevents the material from adhering to the inner wall of the feed box 8. Then, the fixing bolt 12 is turned to rotate, causing its other end to disengage from the inside of the fixing bolt groove 11. Next, the rotating threaded rod 17 is turned to rotate, driving the sliding seat 3 to move downward, which in turn drives the connecting frame 19 to move downward. Then, the downward movement of the connecting frame 19 drives the baffle 18 to move downward, thus adjusting the baffle. After adjusting the gap between the upper outer wall of the plate 18 and the discharge port of the feed box 8, tighten the fixing bolt 12 so that the other end of the outer wall enters the corresponding fixing bolt groove 11 for limiting. Then, control the gap between the upper end of the baffle 18 and the discharge port of the feed box 8 to control the discharge speed, effectively avoiding the discharge speed from being too fast or too slow. Then, the broken material falls into the installation box 2 and is guided by the two inclined plates 15 to fall into the gasifier body 1. Then, when it is necessary to remove the dispersing rod 5, twist the dispersing rod 5 to rotate so that the other end of the outer wall is disengaged from the inside of the dispersing rod groove 14. In this way, the dispersing rod 5 can be removed from the fixed mounting base 6.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
