[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] First embodiment:

[0026] See also Figure 1-Figure 3 As shown, the utility model provides a high-pressure pneumatic flow-assisted warehouse clearing device, the silo bucket 1 is an inverted conical structure, the silo pipe 2 is arranged on the outside of the silo bucket 1, and the silo pipe 2 is spirally distributed or annularly distributed on the outside of the silo bucket 1. The outer end of the silo pipe 2 is connected to the gas source pipeline 5 through the start-up quick-opening valve 4. After the start-up quick-opening valve 4 is opened, the high-pressure gas in the gas source pipeline 5 flows into the inside of the silo pipe 2 through the start-up quick-opening valve 4. After the start-up quick-opening valve 4 is closed, the gas inside the silo pipe 2 is blocked;

[0027] The outer wall of the silo hopper 1 is provided with a plurality of nozzles 3, and the external air inlet end of the nozzles 3 is connected with the silo pipe 2, and the gas in the silo pipe 2 can enter the silo hopper 1 through the nozzles 3, so that the high-pressure gas impacts the inner wall of the silo hopper 1, and clears the inner wall of the silo hopper 1;

[0028] Specifically, in the structure of the nozzle 3, the nozzle 3 is detachably connected to the silo bucket 1, and the nozzle 3 includes a columnar gas bin 301, the inner end of the columnar gas bin 301 extends into the interior of the silo bucket 1, and is penetrated by a through hole 303, and the through hole 303 is arranged close to the side wall of the columnar gas bin 301. By starting the quick-opening valve 4, the high-pressure gas can be controlled. After the quick-opening valve 4 is started, the high-pressure gas in the gas source pipeline 5 is guided to the interior of the bypass bin pipe 2. After the gas enters the columnar gas bin 301, it enters through the through hole 303 on the columnar gas bin 301. Enter the silo bucket 1 and when the nozzle 3 is installed, the through hole 303 is set toward the bottom of the silo bucket 1. The through hole 303 can be in a vertical downward or inclined downward state, which can not only reduce the contamination of the through hole 303 by the material, but also when the through hole 303 is exhausted, the through hole 303 uses the high-pressure gas discharged downward to impact the inner wall of the silo bucket 1, and clear the inner wall of the silo bucket 1 to break up and remove the blocked material, loosen it and restore fluidity, which has a good cleaning effect on the inner wall of the silo bucket 1.

[0029] The second embodiment is different from the first embodiment in that:

[0030] See also Figure 1 , Figure 2 As shown, the warehouse winding pipe 2 has a multi-section structure, one end of which is blocked, and the other end is connected to the gas source pipeline 5 by starting the quick-opening valve 4. After the gas is introduced into the multi-section warehouse winding pipe 2, the gas passes through the nozzle 3 to introduce high-pressure gas into the silo bucket 1, and the high-pressure gas can clean the inner wall of the silo bucket 1. Furthermore, the warehouse winding pipe 2 has a multi-section arc pipe structure, and the arc pipe is distributed up and down on the outer wall of the silo bucket 1. The connecting ends of multiple warehouse winding pipes 2 and the quick-opening valve 4 are staggered, which can balance the air intake pressure of the multi-layer nozzles 3 as a whole, so that the air intake effect is better. Furthermore, the warehouse winding pipe 2 is arranged in layers from top to bottom, and the gas flow directions inside the two adjacent layers of warehouse winding pipes 2 are arranged in opposite directions, so that the air intake pressure of the nozzle 3 is balanced as a whole. After the high-pressure gas enters the silo bucket 1, it impacts the gas on the inner wall of the silo bucket 1, and the inner wall of the silo bucket 1 is cleared.

[0031] The third embodiment is different from the first embodiment in that:

[0032] In the structure of the nozzle 3, see Figure 3 As shown, the columnar gas bin 301 is a hollow cylindrical structure as a whole, and an inner tube 307 is provided on the columnar gas bin 301, and the end of the inner tube 307 passes through the outer end surface of the columnar gas bin 301, and the inner end of the inner tube 307 extends into the columnar gas bin 301, and a sealing block 302 is slidably connected to the outer side thereof, and a through hole is provided on the sealing block 302, and the through hole is slidably matched with the inner tube 307, and the outer wall thereof is slidably matched with the inner wall of the columnar gas bin 301. In the structure of the sealing block 302, a thrust accommodating cavity is provided on the side of the inner end of the sealing block 302 facing the inner end of the columnar gas bin 301, and the thrust cavity is staggered with the through hole 303, and the through hole 303 is in a connected state with the inner tube 307;

[0033] After the inner tube 307 is ventilated, the gas is guided to the thrust accommodating chamber through the inner tube 307. As the air pressure in the thrust accommodating chamber increases, the sealing block 302 overcomes the elasticity of the thrust spring 306. The thrust spring 306 is compressed, and the sealing block 302 slides inside the columnar gas bin 301. When the sealing block 302 moves away from the columnar gas bin 301, the through hole 303 is opened, and the gas enters the silo bucket 1 through the through hole 303. The high-pressure gas is used to clear the blockage of the inner wall of the silo bucket 1. After the quick-opening valve 4 is closed, the gas is no longer introduced into the silo pipe 2 and the nozzle 3. The elasticity of the thrust spring 306 is used to push the sealing block 302 to reset. The sealing block 302 blocks the through hole 303 to avoid contamination and blockage caused by materials entering the through hole 303. This can not only meet the requirements of clearing the granular materials, but also have a certain clearing effect on the liquid materials.

[0034] Specifically, the inner end of the columnar gas bin 301 is an outwardly convex arc structure, and the through hole 303 is eccentrically arranged. The inclination direction of the through hole 303 can be adjusted during installation according to the usage. In the installation limiting structure of the nozzle 3, the silo bucket 1 is penetrated with an installation groove 101 corresponding to the plug-in of the columnar gas bin 301, the columnar gas bin 301 is provided with an insert block 304, and the silo bucket 1 is provided with a limiting groove 102 corresponding to the plug-in of the insert block 304, see Figure 3 As shown, the columnar gas bin 301 is inserted into the installation groove 101, and the insert block 304 is inserted into the limiting groove 102 to limit the columnar gas bin 301. The installation ring 305 is installed on the outside of the columnar gas bin 301 by threaded connection. The installation ring 305 is used to limit the columnar gas bin 301, so as to achieve overall fixation of the columnar gas bin 301 and make the installation more secure.

[0035] A flexible joint is provided around the end of the warehouse tube 2 toward the inner tube 307, and the flexible joint is threadedly connected to the outer end of the inner tube 307 through threads.

[0036] 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.
