[0002] Air cannon, also known as air flow aid, arch breaker and blockage clearer, is a strong airflow of compressed gas that is suddenly ejected at a speed exceeding Mach 1 (the speed of sound) and directly rushes into the blocked fault area where bulk materials are stored. This sudden release of expansion shock wave overcomes the static friction of the material and allows the material in the container to resume flowing. At present, in the normal production process of the blast furnace coal injection workshop, the type of coal changes frequently, the material viscosity is high, the silo is severely adhered, and the material is not discharged smoothly, resulting in frequent material collapse. Usually, electric shock vibration and air cannon are used to perform dual functions.

The unsafe factors are too high and the processing time is too long, which brings great troubles to production and safety. Therefore, an air cannon multi-angle adjustment device is proposed to solve the above problems. Utility Model Content

[0024] An air cannon multi-angle adjustment device comprises an air cannon body 1, a raw coal bin 11 and a wind-locking belt scale 12, an output pipe 2 is installed inside the air cannon body 1, a first flange 3 is installed outside the output pipe 2, a built-in pipe 4 is rotatably connected to the inside of the output pipe 2, a limit ring 5 is fixedly connected to the outside of the built-in pipe 4, a protective sleeve 6 is fixedly connected to the outside of the built-in pipe 4, a second flange 8 is rotatably connected to the outside of the built-in pipe 4, a fixed pipe 9 is fixedly connected to the outside of the second flange 8, and a seamless bent pipe 10 with an equal aperture is connected to one end of the built-in pipe 4 away from the limit ring 5.

[0025] A first sealing sleeve 13 is fixedly connected to the outer side of the first flange 3, and the first sealing sleeve 13 is rotatably connected to the built-in pipe 4, and the first sealing sleeve 13 fits the built-in pipe 4. This arrangement enables the first sealing sleeve 13 to enhance the sealing effect between the built-in pipe 4 and the first flange 3, and reduce the occurrence of air leakage from the first flange 3 of the gas gun; a second sealing sleeve 14 is fixedly connected to the outer side of the second flange 8, and the second sealing sleeve 14 is rotatably connected to the built-in pipe 4, and the second sealing sleeve 14 fits the built-in pipe 4. This arrangement enables the second sealing sleeve 14 to enhance the sealing effect between the built-in pipe 4 and the second flange 8 , reducing the occurrence of air leakage from the second flange 8 of the gas gun; the end of the fixed pipe 9 away from the second flange 8 is fixedly connected to the raw coal bunker 11, the built-in pipe 4 runs through the raw coal bunker 11, and the seamless elbow 10 is arranged on the inner side of the raw coal bunker 11. This arrangement enables the installation of the fixed pipe 9 and determines the position of the seamless elbow 10, so that the seamless elbow 10 can act on the inner side of the raw coal bunker 11; the outer side of the protective sleeve 6 is fixedly connected with rubber bumps 7 of equal size, and the number of rubber bumps 7 is several. This arrangement allows the rubber bumps 7 to increase the friction to a certain extent, making it easier to rotate the built-in pipe 4.

[0026] Working process: During the normal production process in the blast furnace coal injection workshop, the raw coal bin 11 cooperates with the air-locking belt scale 12 installed at the bottom thereof to operate. Due to the frequent changes in coal types and high material viscosity, the inner side of the raw coal bin 11 is severely bonded, and the material is not discharged smoothly, resulting in frequent material bursting. Under normal circumstances, the air cannon body 1 can be used to work on the raw coal bin 11. The air cannon generated by the air cannon body 1 is ejected from the output pipe 2, and then the air cannon is transported to the seamless elbow 10 through the built-in pipe 4. The opening of the seamless elbow 10 works downward under normal circumstances. The air cannon is ejected from the seamless elbow 10, acting on the inner side of the raw coal bin 11 to dredge the raw coal bin 11. When encountering severe material adhesion, hold the protective sleeve 6 and rotate the built-in pipe 4. The built-in pipe 4 is installed through the first flange 3 and the second flange 8. The first sealing sleeve 13 enhances the built-in pipe 4 and the first method The sealing effect between the flanges 3 reduces the occurrence of air leakage from the first flange 3 of the air gun. The second sealing sleeve 14 enhances the sealing effect between the built-in pipe 4 and the second flange 8, reducing the occurrence of air leakage from the second flange 8 of the air gun. The rubber protrusion 7 on the outside of the protective sleeve 6 can increase the friction force, making it easier to rotate the built-in pipe 4. The outer ring of the limit ring 5 cannot pass through the circle of the first flange 3, so that the limit ring 5 limits the built-in pipe 4, so that the built-in pipe 4 will not separate from the output pipe 2. The built-in pipe 4 drives the seamless elbow 10 to rotate, thereby increasing the range of action of the seamless elbow 10, which can effectively break up the materials within the effective diameter range of the air cannon body 1, increase the operating area, maximize the effect of the air cannon body 1, reduce the downtime caused by fluffing materials, realize mechanical processing of fluffing materials, and reduce the hidden dangers of human processing.
