Biomass gasification furnace

Abstract

This utility model discloses a biomass gasification furnace, including a biomass gasification furnace body. A fixing plate is fixedly connected to the surface of the biomass gasification furnace body. A conveying pipe is fixedly connected to the end of the fixing plate away from the biomass gasification furnace body. A geared motor is fixedly connected to one end of the conveying pipe. The output shaft of the geared motor movably passes through and extends into the interior of the conveying pipe. When material is conveyed to the top of the conveying pipe, the output shaft of the geared motor simultaneously drives the fixing plate to rotate. Multiple material plates on the fixing plate rotate accordingly. The inclined design of the material plate near the output shaft helps to disperse the material. Then, with the help of centrifugal force, the dispersed material is thrown into the discharge hopper, so that the material enters the biomass gasification furnace body evenly. The heat-resistant silicone scraper on the material plate rotates synchronously with the material plate and continuously contacts the inner wall of the top of the conveying pipe near the discharge port, scraping off the material adhering in this area, realizing the cleaning of the top of the conveying pipe and avoiding the accumulation of material residue.

Description

Technical Field

[0001] This utility model belongs to the technical field of biomass gasification furnaces, and particularly relates to a biomass gasification furnace. Background Technology

[0002] A biomass gasifier is a device that converts biomass materials, such as straw and wood waste, into combustible gas. The working principle of a biomass gasifier is to heat the biomass materials to cause a pyrolysis reaction, generating gaseous fuel, liquid and solid residue. Among them, gaseous fuel is a green energy source because its raw materials are renewable and have a small impact on the environment, and it has great potential for promotion.

[0003] Biomass materials are prone to accumulating and sticking to the pipe wall near the discharge port at the top of the conveying pipe due to slowed flow rate and changes in spatial shape. This may cause poor discharge, require frequent shutdowns and manual cleaning, and affect the continuous operation of the equipment. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a biomass gasification furnace. When the material is conveyed to the top of the conveying pipe, the output shaft of the geared motor simultaneously drives the fixed disk to rotate. Multiple material plates on the fixed disk rotate accordingly. The inclined design of the material plate near the output shaft helps to disperse the material. Then, with the help of centrifugal force, the dispersed material is thrown into the discharge hopper, so that the material enters the biomass gasification furnace body evenly. The heat-resistant silicone scraper on the material plate rotates synchronously with the material plate and continuously contacts the inner wall of the top of the conveying pipe near the discharge port, scraping off the material adhering in this area, achieving cleaning of the top of the conveying pipe and avoiding the accumulation of material residue.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a biomass gasification furnace, comprising a biomass gasification furnace body, a fixed plate fixedly connected to the surface of the biomass gasification furnace body, a feeding pipe fixedly connected to the end of the fixed plate away from the biomass gasification furnace body, a geared motor fixedly connected to one end of the feeding pipe, the output shaft of the geared motor movably penetrating and extending into the interior of the feeding pipe, a spiral blade fixedly connected to the output shaft of the geared motor, a feed hopper fixedly connected to the surface of the feeding pipe, a discharge hopper fixedly connected to the surface of the feeding pipe, the interiors of the feed hopper and the discharge hopper being connected to the interior of the feeding pipe, a fixed disc fixedly connected to the output shaft of the geared motor, the fixed disc being rotatably connected to the interior of the feeding pipe, a plurality of material plates fixedly connected to the surface of the fixed disc, a scraper fixedly connected to one end of each material plate, and an inclined surface at the end of each material plate corresponding to the position of the output shaft of the geared motor.

[0006] Furthermore, a support base is provided at the bottom of the geared motor, and a controller is fixedly connected to the surface of the support base. The controller is electrically connected to the geared motor through wires.

[0007] Furthermore, the scraper is made of heat-resistant silicone, and the surface of the scraper is in contact with the inner wall of the conveying pipe.

[0008] Compared with the prior art, the beneficial effects of this utility model are: When the material is conveyed to the top of the conveying pipe, the output shaft of the geared motor simultaneously drives the fixed disk to rotate. Multiple material plates on the fixed disk rotate accordingly. The inclined design of the material plate near the output shaft helps to disperse the material. Then, with the help of centrifugal force, the dispersed material is thrown into the discharge hopper, so that the material enters the biomass gasification furnace body evenly.

[0015] See appendix Figure 1-3 As shown, a biomass gasification furnace includes a biomass gasification furnace body 1. A fixing plate 2 is fixedly connected to the surface of the biomass gasification furnace body 1. A feeding pipe 3 is fixedly connected to one end of the fixing plate 2 away from the biomass gasification furnace body 1. A geared motor 8 is fixedly connected to one end of the feeding pipe 3. The output shaft of the geared motor 8 movably passes through and extends into the interior of the feeding pipe 3. A spiral blade 9 is fixedly connected to the output shaft of the geared motor 8. A feed hopper 4 and a discharge hopper 6 are fixedly connected to the surface of the feeding pipe 3. The interiors of the feed hopper 4 and the discharge hopper 6 are both connected to the interior of the feeding pipe 3. A fixing disk 10 is fixedly connected to the output shaft of the geared motor 8. The fixing disk 10 is rotatably connected to the interior of the feeding pipe 3. Multiple material plates 11 are fixedly connected to the surface of the fixing disk 10. A scraper blade 12 is fixedly connected to one end of each material plate 11. The end of the material plate 11 corresponding to the position of the output shaft of the geared motor 8 is set at an angle.

[0016] A support base 5 is provided at the bottom of the geared motor 8, and a controller 7 is fixedly connected to the surface of the support base 5. The controller 7 is electrically connected to the geared motor 8 through wires.

[0017] The scraper blade 12 is made of heat-resistant silicone scraper blade 12, and the surface of the scraper blade 12 is in contact with the inner wall of the conveying pipe 3.

[0018] Working principle: During use, biomass material enters the conveying pipe 3 through the feed hopper 4. The controller 7 starts the reduction motor 8, and the output shaft of the reduction motor 8 synchronously drives the spiral blades 9 to rotate. The spiral blades 9 use the spiral propulsion to continuously convey the material in the conveying pipe 3 upward. When the material is conveyed to the top of the conveying pipe 3, the output shaft of the reduction motor 8 simultaneously drives the fixed disk 10 to rotate. The multiple material plates 11 on the fixed disk 10 rotate accordingly. The inclined design of the material plates 11 near the output shaft helps to disperse the material. Then, centrifugal force is used to further disperse the material. The material is thrown into the discharge hopper 6, so that the material enters the biomass gasification furnace body 1 evenly. The heat-resistant silicone scraper 12 on the material plate 11 rotates synchronously with the material plate 11 and continuously contacts the inner wall of the top of the conveying pipe 3 near the discharge port, scraping off the material adhering in this area, realizing the cleaning of the top of the conveying pipe 3, avoiding the accumulation of material residue, and ensuring the long-term smooth flow of the conveying pipe 3. The geared motor 8 is stably supported by the support base 5. The controller 7 can flexibly adjust the operating status of the geared motor 8, such as start / stop and speed, so as to adapt to the conveying needs of biomass materials with different humidity and types.
