Description

Technical Field

[0001] This utility model relates to the field of biomass gasification equipment technology, and more specifically, to a slag removal device for a high-temperature furnace for co-production of biomass and gas. Background Technology

[0002] Biomass gasification is a clean energy process that uses agricultural and forestry waste biomass raw materials such as crop straw, agricultural waste, sawdust, and wood shavings to process into biomass pellet fuel. Biomass pellet fuel is pyrolyzed and gasified into combustible gas at high temperatures. Biomass gasification technology turns ordinary straw, sawdust, and other waste into clean fuel. In particular, it is expected to effectively solve the environmental pollution problem caused by straw burning in plain areas, protect the ecological environment, and increase energy supply. Traditional gasification devices use a feeding machine to feed raw materials into the biomass gasification furnace to produce fuel gas through pyrolysis and reduction reactions. Only one biomass gasification furnace is used to produce fuel gas, resulting in low production efficiency.

[0003] To address the aforementioned issues, patent document publication number CN220376618U discloses a downdraft high-temperature gasifier, comprising a fluidized bed conveying mechanism, a screw conveyor feeding mechanism, a fluidized bed gasifier body, a carbonization furnace feeding mechanism, a carbonization furnace body, and a gas main pipe.

[0004] However, it still has some drawbacks in actual use. For example, the gasifier body of the above device is equipped with a fluidized bed blower at the bottom for oxygen supply, but the pipe connecting the blower and the gasifier is not equipped with a corresponding slag discharge structure. When the carbon slag accumulates in the pipe for a long time, it will hinder the airflow, thereby reducing the material combustion efficiency and reducing the practicality of the device to a certain extent. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a slag removal device for a high-temperature furnace for co-production of carbon and gas, so as to solve the problem that the existing technology lacks a slag discharge structure in the connecting pipe between the blower and the gasifier.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a slag removal device for a high-temperature furnace for co-production of carbon and gas, comprising a connecting pipe, and the slag removal device for a high-temperature furnace for co-production of carbon and gas further comprising...

[0007] Mounting cover, the mounting cover being disposed on the top of the communicating pipe;

[0008] A connecting plate is fixedly installed on the right side of the top surface of the mounting cover, and a motor is fixedly installed on the right side of the connecting plate;

[0009] A screw, one end of which is fixedly connected to the drive shaft of a motor, and the other end of which is rotatably connected to the inner wall of the mounting cover;

[0010] The mounting block is threaded onto the surface of the screw rod, and the surface of the mounting block is in contact with the inner wall of the mounting cover. A scraper ring is fixedly mounted on the bottom surface of the mounting block, and the edge of the scraper ring is in contact with the inner wall of the connecting pipe.

[0011] A sealing ring is provided on the right side of the mounting cover, and the inner ring of the sealing ring is in contact with the surface of the screw.

[0012] The system also includes a slag discharge pipe, the top of which is fixedly connected to the bottom of a connecting pipe. A second motor is fixedly installed on the outer wall of the slag discharge pipe. A connecting shaft is fixedly connected to the drive shaft of the second motor. A sealing plate is provided on the surface of the connecting shaft. A sealing ring is provided on the edge of the sealing plate. The surface of the sealing ring is in contact with the inner wall of the slag discharge pipe.

[0013] It also includes a limiting ring, which is fixedly installed on the outer wall of the bottom end of the slag discharge pipe.

[0014] The system also includes a collection box, a fixing plate, a spring, a snap-fit ​​seat, and a limiting plate. The top of the collection box is connected to the bottom of the slag discharge pipe. The fixing plate is positioned opposite each other on the left and right sides of the collection box. One end of the spring is fixedly connected to the surface of the fixing plate, and the other end of the spring is fixedly connected to the inside of the snap-fit ​​seat. The side of the snap-fit ​​seat opposite the spring is snapped into the surface of the limiting ring. The limiting plate is positioned opposite each other on both sides of the surface of the fixing plate, and the surface of the limiting plate is slidably connected to the side of the snap-fit ​​seat.

[0015] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0016] In the above scheme, when the carbon slag inside the connecting pipe needs to be cleaned and removed, the motor drives the screw to rotate, so that the mounting block installed on the surface of the screw can move horizontally in the mounting cover, thereby driving the scraper ring set at the bottom of the mounting block to move synchronously. As the scraper ring moves, it can scrape off the carbon slag accumulated inside the connecting pipe and gradually push the carbon slag to the slag discharge pipe, thus completing the treatment of the accumulated carbon slag, avoiding the accumulation of carbon slag in the pipe and obstructing the airflow, ensuring the efficiency of material combustion, and thus improving the practicality of the device.

[0017] When the slag is pushed to the discharge pipe by the scraper ring, the connecting shaft is rotated by the motor, causing the horizontal sealing plate to rotate 90 degrees. At this time, the discharge pipe is open, and the pushed slag enters the collection box for collection. Subsequently, the locking seat can be moved horizontally. At this time, the spring set between the locking seat and the fixed plate is compressed and deformed, and one side of the locking seat disengages from the outer periphery of the limiting ring. Then, the collection box can be moved vertically downward, separating the collection box from the discharge pipe, so that the slag collected in the collection box can be discharged uniformly, further improving the practicality of the device.

[0034] The working process of this utility model is as follows: When the carbon slag inside the connecting pipe 1 needs to be cleaned and removed, the screw 5 is driven to rotate by the motor 4, so that the mounting block 6 installed on the surface of the screw 5 can move horizontally in the mounting cover 2, thereby driving the scraper ring 7 installed at the bottom of the mounting block 6 to move synchronously. Thus, the scraper ring 7 can scrape off the carbon slag accumulated inside the connecting pipe 1 during the movement, and gradually push the carbon slag to the slag discharge pipe 9, thereby completing the treatment of the accumulated carbon slag.
