[0002] In the operation of thermal power generation and metallurgical ironmaking, the materials will be crystallized or solidified due to the influence of raw materials, temperature and weather, so that the materials will adhere to the inner wall of the silo, and the materials adhered to the inner wall will gradually accumulate to form sticky materials. The sticky materials on the inner wall of the silo will accumulate and increase in weight. Since the sticky materials on the inner wall of the silo block the flow of materials, the production quality may be reduced, the composition and performance of the products cannot meet the requirements, and the silo will be blocked, and even the production line will be shut down, which will have a serious impact on production. Therefore, it is necessary to regularly clear the inner wall of the silo.

[0003] Among the existing silo blockage clearing equipment, high-pressure water jet devices and pneumatic blowing devices are mostly used. However, the high-pressure water jet device has great limitations on the material of the materials stored in the silo. The existing pneumatic blowing device mostly has a blowing nozzle that blows materials in a direction corresponding to the silo busbar, with a small blowing range and average clearing effect.

DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0028] First embodiment:

[0029] See also Figure 1-Figure 6 As shown, the utility model provides a high-pressure pneumatic rotary cutting and clearing device, including a conical warehouse body 1, an outer wall of the warehouse body 1 is provided with a warehouse pipe 2 surrounding the outer side of the warehouse body 1, the warehouse pipe 2 is a part of a ring as a whole, and preferably the warehouse pipe 2 is an arc shape, and the two ends of the warehouse pipe 2 are respectively a blocking part 201 and an air inlet part 202, one end of the blocking part 201 is sealed, and the other end of the air inlet part 202 is connected to a horizontally extending pipe, the end of the pipe is connected to the air source pipe 5, and a pressure gas warehouse or an air pump can be provided at the end of the air source pipe 5, and an air pressure control part 4 is connected to the pipe, and the air pressure control part 4 plays a role mainly by controlling the air intake of the pipe, that is, the air intake and closing operation of the auxiliary warehouse pipe 2 are controlled by the air pressure control part 4. After the air pressure control part 4 is turned on, the gas compressed through the air source pipe 5 passes through the air pressure control part 4 and enters the interior of the warehouse pipe 2;

[0030] The warehouse bypass pipe 2 and the warehouse body 1 are connected through the explosion-proof pipe 3, and the explosion-proof pipe 3 is connected to the warehouse bypass pipe 2 or the warehouse body 1 by welding or flange connection. The explosion-proof pipe 3 is distributed circumferentially with the axis of the warehouse body 1 as the reference. The position of the explosion-proof pipe 3 is designed according to actual needs. When the gas enters the explosion-proof pipe 3 through the air pressure control component 4 and the warehouse bypass pipe 2, and the high-pressure gas can be guided to the interior of the warehouse body 1 through the explosion-proof pipe 3, the connecting line of the centers of the two connecting pipe openings of the explosion-proof pipe 3 constitutes a pipeline line 301, and the high end of the pipeline line 301 is away from the busbar of the warehouse body 1 and deflected at a certain angle relative to the busbar of the warehouse body 1.

[0031] Specifically, see Figure 1 As shown, the lower end of the explosion tube 3 is connected to the warehouse body 1, the busbars of the explosion tube 3 and the warehouse body 1 are in an inclined state, and the lower end thereof is connected to the warehouse body 1.

[0032] Specifically, the explosion tube 3 is a straight tube or an arc tube, see Figure 4-Figure 6As shown, the horizontal projection of pipeline line 301 and the busbar of warehouse body 1 are deflected at an angle of 25°-40°. The busbars of pipeline line 301 and warehouse body 1 are horizontally projected onto the same vertical plane, and the horizontal projection of pipeline line 301 is pipeline projection line 303. The busbar at the connection position between warehouse body 1 and explosion pipe 3 is horizontally projected, and its horizontal projection is busbar projection line 101. Thus, pipeline projection line 303 and busbar projection line 101 are set in the same plane, and pipeline projection line 303 The angle between the pipeline line 301 and the busbar projection line 101 is the deflection angle between the horizontal projection of the pipeline line 301 and the busbar projection of the silo 1, as shown in the projection angle 302 in the figure, which is 25°-40°. After the high-pressure gas enters the interior of the silo 1 through the bottom opening of the explosion pipe 3, and because the inner wall of the silo 1 is conical, the high-pressure gas deflects and rotates along the inner wall of the silo 1 to increase the range of the explosion, assist in guiding the material on the inner wall of the silo 1 downward, and clear the inner wall of the silo 1.

[0033] See also Figure 5 FIG. 1 is a schematic diagram of the state when the explosion pipe 3 is in a straight pipe state and the angle between the pipeline projection line 303 and the generatrix projection line 101 is 32°, see Figure 6 As shown, it is a schematic diagram of the state when the explosion tube 3 is an arc tube and the angle between the pipeline projection line 303 and the busbar projection line 101 is 34°. When the high-pressure gas enters the interior of the warehouse body 1 through the explosion tube 3, the inner wall of the warehouse body 1 can be flushed in a rotary cutting manner to achieve cleaning of the inner wall of the warehouse body 1. Not only is the cleaning effect good, but the cleaning area is larger and there are fewer cleaning dead corners.

[0034] The air pressure control component 4 is installed in the pipeline. The air pressure control component 4 is a gas releaser that controls the lifting pressure on the corresponding pipeline, regulates and releases the gas in the pipeline, and realizes the purpose of automatic control of the pipeline pressure and regulation of the gas pressure. When the gas releaser is turned on, the compressed air can be instantly blown into the silo to clean the materials adhering to the silo wall, thereby achieving the effect of clearing the warehouse; the air pressure control component 4 is a pneumatic quick-opening valve installed on the pipeline, with the compressed air generated by the air source pipeline 5 as the power source. When the pneumatic quick-opening valve is opened, the compressed air can be instantly blown into the silo to clean the materials adhering to the silo wall, thereby achieving the effect of clearing the warehouse. The air pressure control component 4 can ensure the constancy of the gas pressure and keep the silo body 1 stable. The design has a wide spraying range, greatly reduces user costs and daily maintenance, and is particularly suitable for installation in narrow spaces.

[0035] Second embodiment:

[0036] There are multiple groups of winding pipes 2, and the multiple groups of winding pipes 2 are distributed along the height direction of the silo body 1, and the overall arc is set close to the conical surface of the outer wall of the silo body 1. From top to bottom, the diameter of the arc pipe formed by the multiple groups of winding pipes 2 gradually decreases. The diameter of the arc pipe refers to the diameter of the arc formed by the winding pipe 2 with the axis of the silo body 1 as the center. The diameter of the arc pipe is arranged according to the size of the silo, see Figure 1-Figure 3 As shown, the air inlet pipes of the multiple groups of warehouse pipes 2 are all connected to the gas source pipe 5 through the same air inlet pipe. Further, the upper and lower adjacent groups of explosion-proof pipes 3 are staggered with the connection ports of the warehouse body 1. When the gas is guided to the interior of the warehouse body 1 through the explosion-proof pipes 3, the compressed gas is flushed on the inner wall of the warehouse body 1 through the multi-layer explosion-proof pipes 3, and there are fewer dead corners. Further, the upper and lower adjacent groups of warehouse pipes 2 are staggered with the ports connected to the air pressure control member 4. Figure 2 As shown, the sealed end of the lower layer of the warehouse winding pipe 2 corresponds to the open end of the upper layer of the warehouse winding pipe 2. In this arrangement, when the high-pressure gas enters the interior of the warehouse winding pipe 2 through the air inlet portion 202, the high-pressure gas pressures derived by the explosion-proof pipe 3 located at the end of the air inlet portion 202 and the explosion-proof pipe 3 located at the end of the blocking portion 201 are different, that is, the gas pressure of the explosion-proof pipe 3 close to the end of the air inlet portion 202 is large, and the gas pressure of the explosion-proof pipe 3 located at the end of the blocking portion 201 is relatively small. In this embodiment, the staggered or reverse arrangement of the multiple layers of the warehouse winding pipes 2 can reduce the uneven cleaning effect in some areas caused by the gas pressure difference.

[0037] Reverse setting see Figure 3 As shown, the air inlet portion 202 on the upper layer of the warehouse winding pipe 2 corresponds to the blocking portion 201 on the lower layer of the warehouse winding pipe 2, the blocking portion 201 on the upper layer of the warehouse winding pipe 2 corresponds to the air inlet portion 202 on the lower layer of the warehouse winding pipe 2, the inclination directions of the explosion-proof tubes 3 on the upper and lower layers of the warehouse winding pipes 2 are consistent, the air inlet directions of the upper and lower layers of the warehouse winding pipes 2 are in opposite directions, and the outlet direction of the explosion-proof tubes 3 remains unchanged.

[0038] The staggered setting means that the air inlet parts 202 on the multiple layers of the warehouse pipes 2 are staggered with each other, the gas directions of the upper and lower warehouse pipes 2 are consistent, and the inclination directions of the explosion-proof tubes 3 on the upper and lower warehouse pipes 2 are consistent. After the high-pressure gas is introduced into the warehouse pipes 2, part of the clearing gap caused by the low pressure can be offset, thereby improving the overall clearing effect on the inner wall of the warehouse body 1.

[0039] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
