Description

Technical Field

[0001] The utility model relates to the technical field of gasifiers, in particular to a rice husk moving bed gasifier system. Background Art

[0002] A gasifier is a new type of kitchen stove or power generation equipment. Its main function is to pyrolyze the rice husks entering the gasifier to produce rice husk charcoal and a large amount of by-product biomass gas. The high-temperature biomass gas is sent into the "regenerative oxidation chamber", oxidized after air distribution, and then enters the waste heat boiler for heat exchange. The heat energy in the gas is fully recovered and utilized, converted into steam, hot water or other forms of heat energy output, and supplied for various fields such as heating, power generation or industrial production, thus realizing the maximum utilization and recycling of energy.

[0003] When the current moving bed gasifier is in use, after the rice husks undergo high-temperature pyrolysis and carbonization processes inside the gasifier, a certain amount of solid residues will be generated. These residues are mainly carbonized rice husk ashes, which will gradually accumulate on the conveyor belt. When the conveyor belt works, the rice husk ashes will be discharged, but there will still be a small amount of ashes remaining on the conveyor belt, which will increase the operating load of the conveyor belt and affect its service life. For this reason, we provide a rice husk moving bed gasifier system. Summary of the Utility Model

[0004] The utility model provides a rice husk moving bed gasifier system to solve the technical problem that when the rice husks undergo high-temperature pyrolysis and carbonization processes inside the gasifier, a certain amount of solid residues will be generated.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] First embodiment

[0027] As shown in Attached Figure 1 and Attached Figure 2 As shown: A rice husk moving bed gasifier system includes a gasifier body 1 and a conveyor belt 2 arranged inside the gasifier body 1. The conveyor belt 2 can be used to convey and discharge rice husk ash: a cleaning scraper 3 is arranged below the conveyor belt 2 for scraping the residual ash on the conveyor belt 2.

[0028] The upper surface of the gasifier body 1 is fixedly inlaid with a feed cylinder 8 and a smoke exhaust pipe 9. The smoke exhaust pipe 9 is located on the right side of the feed cylinder 8. The feed cylinder 8 facilitates the staff to add rice husk raw materials, and the smoke exhaust pipe 9 can discharge the biomass gas.

[0029] The bottom surface of the gasifier body 1 is fixedly connected with a group of supports 10. The arranged supports 10 can stably support the gasifier body 1 and enable it to maintain a stable state during operation.

[0030] Second embodiment

[0031] As shown in Attached Figure 2 and Attached Figure 3As shown: The jacking assembly 4 is arranged on one side of the cleaning scraper 3 and includes two top plates 401 installed on one side surface of the cleaning scraper 3 and a jacking structure arranged inside the gasifier body 1. The jacking structure of the jacking assembly 4 includes a motor 402 installed on the inner bottom wall of the gasifier body 1. The output end of the motor 402 is fixedly connected with a rotating rod 403. Two eccentric wheels 404 are fixedly connected to the outer surface of the rotating rod 403. Each eccentric wheel 404 is located below the top plate 401. By the operation of the motor 402, the rotating rod 403 will drive the eccentric wheels 404 to rotate, and the eccentric wheels 404 will push the top plates 4 to move, and the cleaning scraper 3 will repeatedly contact the conveyor belt 2, so as to complete the removal of the residual ash on the conveyor belt 2.

[0032] The rear end of the rotating rod 403 is rotatably connected with a support plate 405. The bottom end of the support plate 405 is connected to the inner bottom wall of the gasifier body 1. The set support plate 405 can support the other end of the rotating rod 403, further ensuring the stability of the rotating rod 403 during rotation.

[0033] The bottom surface of the gasifier body 1 is fixedly inlaid with a discharge hopper 6. The discharge hopper 6 is located right below the conveyor belt 2. The conveyor belt 2 will convey the ash into the discharge hopper 6, so as to discharge the ash outside the gasifier body 1.

[0034] Third Embodiment

[0035] As shown in the attached Figure 2 and attached Figure 4 As shown: The pressing-down assembly 5 is arranged on one side of the cleaning scraper 3 and includes two abutting blocks 501 installed on one side surface of the cleaning scraper 3 and a pressing-down structure arranged inside the gasifier body 1. The pressing-down structure of the pressing-down assembly 5 includes sliding rods 502 slidably connected to each abutting block 501. The bottom end of each sliding rod 502 is connected to the inner bottom wall of the gasifier body 1. The top end of each sliding rod 502 is fixedly connected with a baffle 503. A spring 504 is sleeved on the outer surface of each sliding rod 502. When the cleaning scraper 3 rises, it will drive the abutting blocks 501 to compress the spring 504. When the eccentric wheel 404 releases the pushing on the top plate 401, the spring 504 will stretch and push the abutting blocks 501, and the abutting blocks 501 will drive the cleaning scraper 3 away from the conveyor belt 2, so as to avoid damage to the conveyor belt 2 caused by the long-term contact between the cleaning scraper 3 and the conveyor belt 2.

[0036] The right side surface of the cleaning scraper 3 is fixedly connected with a guide plate 7. The guide plate 7 is located above the discharge hopper 6. The set guide plate 7 can guide the ash scraped by the cleaning scraper 3, and can ensure that all the ash enters the discharge hopper 6 and is discharged.

[0037] Working principle: When it is necessary to clean the ash on the conveyor belt 2, start the motor 402. The motor 402 will drive the eccentric wheel 404 to rotate through the rotating rod 403. When the eccentric wheel 404 rotates, it will push the top plate 401. The top plate 401 will drive the cleaning scraper 3 to rise and disengage from the conveyor belt 2. As the conveyor belt 2 rotates, the cleaning scraper 3 will remove the residual ash on the conveyor belt 2, reducing the operating load of the conveyor belt 2 and ensuring its service life. At the same time, the cleaning scraper 3 will drive the abutting block 501 to compress the spring 504. When the eccentric wheel 404 rotates to the lower position, the spring 504 will push the abutting block 501, and the cleaning scraper 3 will descend away from the conveyor belt 2, which can prevent the cleaning scraper 3 from being damaged due to long-term contact with the conveyor belt 2.
