Abstract
Description
Technical Field
[0001] This utility model relates to the field of gasifier technology, specifically to a gasifier ash removal device. Background Technology
[0002] A gasifier is a reactor used to produce coal gas, water gas, and semi-water gas. It uses coal or coke as raw material and air and steam as gasifying agents, undergoing oxidation and reduction reactions in a fixed bed to produce a mixed gas. The specific process includes the oxidation and reduction of coal, generating combustible gases such as carbon monoxide and hydrogen. Gasifiers are widely used in various industrial fields, such as chemical, metallurgical, and machinery manufacturing, as fuel. The produced gas has a high calorific value and is suitable for industrial processes requiring high-temperature combustion.
[0003] During long-term operation, dust gradually accumulates on the inner wall of a gasifier. To prevent dust accumulation and blockage, workers usually use scrapers to clean the dust from the inner wall of the gasifier. However, this method results in high labor intensity and low work efficiency for workers. Therefore, those skilled in the art have provided a dust removal device for gasifiers to solve the problems mentioned in the background art. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This ash-cleaning device for a gasifier uses a first motor to drive a first gear, which in turn drives a second gear to rotate a drum. This causes a scraper to clean the dust from the inner wall of the furnace. An electric push rod drives a lifting rod to move up and down, ensuring the scraper moves up and down against the inner wall of the furnace and guaranteeing effective ash cleaning. A second motor, through a synchronization assembly, drives two threaded rods to rotate synchronously, causing two sliders to move synchronously in a straight line. This allows the scraper to be adjusted according to the diameter of the inner wall of the furnace, ensuring that the scraper contacts the inner wall. This device solves the problem of high labor intensity and low work efficiency caused by workers using scrapers to clean the dust from the inner wall of the gasifier. Attached Figure Description

[0023] Please see Figures 1-5In this embodiment of the present invention, a ash removal device for a gasifier includes a housing 1. A first motor 6 is installed inside the housing 1. The output end of the first motor 6 is connected to a first gear 7. A first bearing 9 is embedded in the bottom surface of the housing 1. A rotating cylinder 4 is connected to the inner ring of the first bearing 9. A second gear 8 is connected to the top of the rotating cylinder 4. The first gear 7 and the second gear 8 mesh. An electric push rod 14 is installed inside the rotating cylinder 4. One end of the electric push rod 14 is connected to a lifting rod 5. The bottom end of the lifting rod 5 is connected to an adjusting box 17. A second motor 16 is installed on the upper surface of the adjusting box 17. A groove 15 is formed at the bottom end of the lifting rod 5. The second motor 16 is located inside the groove 15. A second bearing 18 is embedded in the inner wall of the adjusting box 17. A synchronization component 19 is provided on the inner ring of the second bearing 18. The output end of the second motor 16 is connected to a second... Bearing 18 is connected to synchronization component 19. The inner wall of the regulating box 17 is inlaid with symmetrical third bearings 20. The inner rings of the two third bearings 20 are connected to threaded rods 21. The ends of the two threaded rods 21 that are close to each other are connected to synchronization component 19. The outer surfaces of the two threaded rods 21 are threaded with sliders 23. The outer surfaces of the two sliders 23 are connected with scrapers 24. The first motor 6 drives the first gear 7, which enables the second gear 8 to drive the rotating drum 4 to rotate. By setting an electric push rod 14, the scraper 24 can be driven up and down by the lifting rod 5 to clean the inner wall of the furnace, thereby ensuring the cleaning effect. The second motor 16, through synchronization component 19, can drive the two threaded rods 21 to rotate simultaneously, so that the sliders 23 drive the scraper 24 to move linearly, so that the scraper 24 is matched with the diameter of the inner wall of the furnace.
[0024] The outer surface of the casing 1 is provided with a heat dissipation vent 2, and a filter screen 3 is connected inside the heat dissipation vent 2 to facilitate airflow and thus dissipate heat from the first motor 6. The bottom surface of the casing 1 is connected to two sets of positioning frames 10, and positioning plates 11 are slidably connected inside the two sets of positioning frames 10. By sliding the positioning plates 11 inside the positioning frames 10, the fastening rods 13 can be adjusted according to the diameter of the furnace opening. The inner walls of the two sets of positioning plates 11 are threaded with fastening rods 13, and one end of the two sets of fastening rods 13 is connected to a handle 12.

[0025] Synchronization component 19 includes a first bevel gear 191. The output end of the second motor 16 is connected to the top of the first bevel gear 191 via a second bearing 18. Two threaded rods 21 are each connected to a second bevel gear 192 at their close ends. Both second bevel gears 192 mesh with the first bevel gear 191.

The ends of the two threaded rods 21 that are far apart from each other pass through the slider 23 and extend into the cavity 25. The ends of the two threaded rods 21 that are far apart from each other are connected to a limiting plate 26. Through the cooperation between the cavity 25 and the limiting plate 26, the slider 23 can be limited, preventing the slider 23 from separating from the threaded rod 21.
[0026] The working principle of this utility model is as follows: During use, the second motor 16 first drives the first bevel gear 191 to rotate through the second bearing 18. The first bevel gear 191 drives the second bevel gear 192 to rotate, and the second bevel gear 192 drives the threaded rod 21 to rotate, so that the slider 23 drives the scraper 24 to move linearly and contact the inner wall of the furnace. Then, the first motor 6 drives the first gear 7 to rotate, and the first gear 7 drives the rotating drum 4 to rotate through the second gear 8, so that the scraper 24 rotates on the inner wall of the furnace to clean the dust on the inner wall of the furnace. At the same time, the electric push rod 14 drives the lifting rod 5 to move up and down, so that the scraper 24 moves up and down on the inner wall of the furnace, thereby ensuring the cleaning effect.
