Description

Technical Field

[0001] This utility model relates to the field of anti-clogging technology for biomass gasifiers, and more specifically, to an anti-clogging device for biomass gasifiers. Background Technology

[0002] A biomass gasification furnace is a device that takes biomass raw materials, such as wood chips, sawdust, wheat straw, and rice straw, and feeds them into the furnace after pressing or simple crushing. In an anaerobic environment, the biomass polymers undergo pyrolysis, oxidation, reduction, and reforming reactions, allowing the tar produced by pyrolysis to further crack, ultimately generating combustible gases rich in CO, H2, and CH4. Its raw material sources are wide-ranging, covering agricultural and forestry waste, and due to the inherent characteristics of biomass, it has high gasification activity.

[0003] In existing biomass gasifiers, the feed hopper, as the primary channel for materials to enter the furnace, plays a crucial role in feeding. However, many biomass raw materials, such as straw, firewood, and sludge, often contain a certain amount of moisture during collection and storage due to the influence of the natural environment. When these wet materials enter the feed hopper, under the combined effects of gravity, material compression, and heat conduction within the gasifier, a caking layer easily forms on the inner wall of the feed hopper and at the material accumulation points. As operating time increases, the caking layer thickens, gradually reducing the effective feed opening diameter of the feed hopper. This not only severely affects the feeding speed but also easily causes blockages, forcing the gasifier to shut down for cleaning, significantly reducing production efficiency and increasing maintenance costs.

[0004] In addition, biomass raw materials with a certain moisture content are prone to clumping during storage and transportation. These clumps are dense with low internal porosity. If they are directly fed into the gasifier, uneven heat and mass transfer will occur during the gasification reaction. The outer layer of material may gasify rapidly, while the inner material may not be able to fully contact the gasifying agent, resulting in incomplete gasification. This not only reduces the conversion efficiency of biomass but also produces a large amount of unreacted residue, affecting the quality and output of the gas. This significantly reduces the overall operating performance of the gasifier and causes many problems in actual production.

[0005] In view of this, we propose an anti-clogging device for biomass gasification furnaces. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] The purpose of this invention is to provide an anti-clogging device for a biomass gasification furnace to solve the problems mentioned in the background art.

[0008] 2. Technical Solution

[0009] An anti-clogging device for a biomass gasifier includes a gasifier body, an anti-clogging component on the top of the gasifier body, a rotating seat rotatably connected to the top of the gasifier body, the rotating seat extending into the interior of the gasifier body, a stirring component on the inner wall of the rotating seat, the stirring component including a connecting rod fixedly connected to the inner wall of the rotating seat, a connecting cylinder on the top of the rotating seat, a fixed cylinder rotatably connected inside the connecting cylinder, a fixing cover fixedly connected to the top of the connecting cylinder for limiting the fixed cylinder, a feed hopper on the top of the fixed cylinder, a mounting frame connected to the outer wall of the feed hopper, a drive motor fixedly connected to the bottom of the mounting frame, and a drive seat connected to the output end of the drive motor.

[0010] Preferably, a connecting rod is provided at the top of the connecting rod, and a scraper is provided on the outer circumference of the connecting rod, the scraper contacting the inner wall of the feed hopper.

[0011] Preferably, the outer circumferential wall of the connecting rod is also connected to a breaking blade, and the ends of the plurality of breaking blades are connected to scrapers II, which are in contact with the inner wall of the fixed cylinder.

[0012] Preferably, the outer wall of the connecting cylinder is provided with a groove, and the inner wall of the groove and the outer circumferential wall of the drive seat are fitted together with a transmission belt.

[0013] Preferably, the inner wall of the connecting cylinder is further provided with a groove, and a knocking plate is rotatably connected to the inner wall of a plurality of grooves. A spring is fixedly connected to the outer wall of a plurality of knocking plates, and the ends of a plurality of springs are respectively fixedly connected to the inner wall of the connecting cylinder.

[0015] Preferably, the bottom of the fixed cylinder extends into the interior of the rotating seat, and the sleeve ring is located inside the connecting cylinder.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of this utility model are as follows: In actual use, materials can be put into the feeding hopper for feeding. When the materials enter the feeding hopper, the drive motor can be started to drive the drive seat to rotate. During the rotation of the drive seat, its transmission belt can synchronously drive the connecting cylinder to rotate. During the rotation of the connecting cylinder, multiple striking plates set on the inner wall of the connecting cylinder will pass through multiple arc grooves opened on the outer wall of the sleeve ring in sequence. The striking plates can generate a continuous vibration effect on the sleeve ring in the process of the spring's back and forth compression and release, in conjunction with its rotation. This vibration force can be transmitted to the fixed cylinder fixedly connected to it, thereby vibrating and removing impurities attached to the inner wall of the fixed cylinder, reducing the phenomenon of material caking.

[0018] While the connecting cylinder is vibrating, it can also drive the stirring component to rotate, thus working with scraper one and scraper two to scrape the inner wall of the feed hopper and the fixed cylinder for conveying materials. This better coordinates the vibration to effectively clean the material adhering to the clumps. The cleaned material can then fall into the gasifier body by gravity. In this process, multiple breaking blades can also rotate and break up the clumps of material, thereby reducing the possibility of large clumps falling directly into the gasifier body and causing incomplete combustion, effectively improving the practicality of the feeding process.

[0029] In some embodiments, the fixing cover 290 facilitates the enclosure of the sleeve ring 310 inside the connecting cylinder 250. The outer circumferential wall of the fixing cylinder 300 is also provided with a limiting ring. The top of the limiting ring is attached to the bottom of the sleeve ring 310 but not connected, so that the fixing cylinder 300 can be rotated while limiting and closing.

[0030] The top of the fixed cylinder 300 is provided with a feed hopper 330, the outer wall of the feed hopper 330 is connected to a mounting bracket 340, the bottom of the mounting bracket 340 is fixedly connected to a drive motor 350, and the output end of the drive motor 350 is connected to a drive base 360.

[0031] In some embodiments, the drive motor 350 can be a common model available on the market, and is connected to the drive seat 360 via a coupling, so as to facilitate the rotation of the connecting cylinder 250 with the transmission belt 370.

[0032] Specifically, a connecting rod 220 is provided at the top of the connecting rod 210, and a scraper 230 is provided on the outer circumference of the connecting rod 220. The scraper 230 contacts the inner wall of the feed hopper 330, which facilitates cleaning of the inner wall of the feed hopper 330.

[0033] In some embodiments, a baffle can be connected to the top of the feed hopper 330 via a hinge, and the baffle can be fixed by means of a pin. All of the above belong to the prior art.

[0034] Furthermore, the outer circumference of the connecting rod 220 is also connected to a breaking blade 240, and the ends of the multiple breaking blades 240 are connected to scrapers 241. The scrapers 241 are in contact with the inner wall of the fixed cylinder 300, which facilitates cleaning of the inner wall of the fixed cylinder 300.

[0035] In some embodiments, the bottom circumferential outer wall of the fixed cylinder 300 is in contact with the circumferential inner wall of the rotating seat 200 and is rotatably connected to the circumferential inner wall of the rotating seat 200.

[0036] Furthermore, the outer wall of the connecting cylinder 250 is provided with a slot 251, and the inner wall of the slot 251 and the outer circumferential wall of the drive seat 360 are fitted together with a transmission belt 370, so as to drive the connecting cylinder 250 to rotate through the transmission belt 370.

[0037] Furthermore, the inner wall of the connecting cylinder 250 is provided with grooves 260, and multiple grooves 260 are rotatably connected to the inner walls of the grooves 260. Multiple springs 280 are fixedly connected to the outer walls of the multiple springs 270, and the ends of the multiple springs 280 are respectively fixedly connected to the inner wall of the connecting cylinder 250.

[0038] It is worth noting that a sleeve ring 310 is fixedly sleeved on the outer circumference of the fixed cylinder 300. The outer circumference of the sleeve ring 310 is provided with an arc groove 320, which facilitates the vibration of the inner wall of the fixed cylinder 300 in conjunction with the striking plate 270.

[0039] It is worth noting that the bottom of the fixed cylinder 300 extends into the interior of the rotating seat 200 and rotates inside it, reducing dust from entering the interior of the connecting cylinder, and the sleeve ring 310 is located inside the connecting cylinder 250.

[0042] Working Principle: In actual use, materials can be fed into the feed hopper 330. When the materials enter the feed hopper 330, the drive motor 350 can be started to drive the drive base 360 ​​to rotate. During the rotation of the drive base 360, its transmission belt 370 can synchronously drive the connecting cylinder 250 to rotate. During the rotation of the connecting cylinder 250, multiple striking plates 270 set on the inner wall of the connecting cylinder 250 will pass through multiple arc grooves 320 opened on the outer wall of the sleeve ring 310 in sequence. During the compression and release of the spring, the striking plates 270, in conjunction with the rotation, will generate a continuous vibration effect on the sleeve ring. This vibration force can be transmitted to the fixed cylinder 300 fixedly connected to it, thereby vibrating the inside of the fixed cylinder 300. The impurities adhering to the wall are vibrated and detached, reducing the phenomenon of material caking. At the same time as this knocking vibration, the connecting cylinder 250 can also drive the stirring component to rotate, thereby working with the scraper 1 230 and scraper 2 250 to scrape the inner wall of the feed hopper 330 and the fixed cylinder 300 for conveying materials. This better coordinates the vibration to effectively clean the adhering and caking material. The cleaned material can fall into the gasifier body 100 by gravity. In this process, the multiple breaking blades 240 can also rotate and break up the clumps of material, thereby reducing the situation where large clumps fall directly into the gasifier body 100 and cause incomplete combustion, effectively improving the practicality of feeding.
