Description

Technical Field

[0001] The utility model relates to the technical field of gas stoves, in particular to a gas stove with a coal cinder recovery structure. Background Technique

[0002] A gas stove uses coal, air, and water vapor as raw materials and gasifying agents, and produces clean and environmentally friendly combustible gas - coal gas through a gasification reaction process in a closed container. Now, a gas stove with the application number CN201920068860.7 is retrieved. This invention increases a furnace ring connected to the furnace body on the top cover of the furnace, that is, utilizes the outer space of the conical part of the automatic coking machine to raise the height of the gas stove to a reasonable size. At the same time, the inlet of the upward gas pipeline is changed to be connected to the furnace ring, solving the problem of gas deflection caused by the upward gas exiting from one side of the top cover of the furnace, enabling various gasifying agents to be evenly distributed in the furnace and improving the gas production of the gas stove.

[0003] Similar to the above gas stove: Although the problem of gas deflection caused by the upward gas exiting from one side of the top cover of the furnace is solved by raising the height of the gas stove to a reasonable size and changing the inlet of the upward gas pipeline to be connected to the furnace ring, first, a large amount of coal cinder will adhere to the inner wall during the use of the gas stove, and long-term adhesion is prone to phenomena such as accumulation, blockage, and difficulty in cleaning. Second, the gas stove equipment will add a filtering device at the exhaust port to improve the purity of the gas, but a large amount of coal cinder that can continue to burn will be treated by the filtering device and not fully utilized.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a gas stove with a coal cinder recovery structure is proposed to achieve a more practical value purpose. Content of the Utility Model

The end of the connecting rod 11 far from the rotating shaft 8 is connected to a scraping plate 12. The outer wall of the side of the scraping plate 12 far from the connecting rod 11 abuts against the inner wall of the furnace body 1. The rotating shaft 8 can be driven to rotate by the servo motor 10. When the rotating shaft 8 rotates to drive the stirring rods 9 to stir, it also drives the connecting rods 11 to rotate. The connecting rod 11 rotates to drive the scraping plate 12 to rotate, so as to scrape off impurities such as cinder attached to the inner wall of the furnace body 1, which is convenient for improving the cleanliness of the inner wall of the furnace body 1 and enabling the cinder attached to the inner wall of the furnace body 1 to continue to be smelted.

[0022] An insulating layer 13 is provided on the inner wall of the furnace body 1. The insulating layer 13 is made of materials such as insulating cotton to improve the heat insulation performance of the furnace body 1. An air outlet 14 is provided on one side of the top of the furnace body 1. Through the air outlet 14, the gas can be discharged into the exhaust duct 15.

The hot air is blown upward into the furnace body 1 through the small holes in the air blowing plate 5, so as to achieve better heating and make the smelting more smooth. The servo motor 10 can drive the rotating shaft 8 to rotate. The rotation of the rotating shaft 8 drives the stirring rod 9 to stir the coal stones, so that the coal stones can be fully heated and smelted. While the rotation of the rotating shaft 8 drives the stirring rod 9 to stir, it also drives the connecting rod 11 to rotate. The rotation of the connecting rod 11 drives the scraper 12 to rotate, so as to scrape off impurities such as cinder attached to the inner wall of the furnace body 1, which is convenient for improving the cleanliness of the inner wall of the furnace body 1 and enabling the cinder attached to the inner wall of the furnace body 1 to continue smelting. The exhaust fan 151 makes the exhaust pipeline 15 generate suction to facilitate the suction of the gas in the furnace body 1 for collection. A filter plate 16 is arranged inside one side of the exhaust pipeline 15 close to the air outlet 14. The filter plate 16 plays a filtering role. Some unreacted cinder particles and waste residues will enter the exhaust pipeline 15 with the upward gas flow of the gas and be blocked and filtered by the filter plate 16. The driving motor 20 can drive the movable shaft 18 to rotate, thus driving the brush 19 to rotate, so that the brush brushes the surface of the filter plate 16, so as to brush off the cinder filtered by the filter plate 16 for collection. At the same time, brushing off the cinder can prevent the filter plate 16 from being blocked. The brushed-off cinder will fall into the blanking chute 21 by gravity. When the blanking chute 21 collects a certain amount of cinder, the solenoid valve 23 can be opened to make the cinder fall back into the furnace body 1 through the recovery pipeline 22 for re-smelting, realizing the function of recycling cinder. Opening the furnace door 24 can discharge the smelted coal stones, and the transparent observation window 25 is convenient for observing the reaction situation.
