During daily ash delivery work, more than a dozen pipelines may simultaneously deliver ash to the silo body, which may cause the feed pipeline layout in the central area of ​​the silo roof to occupy a large space, which is not conducive to the layout of the central feed and the use of dust collection equipment. The safety of the silo roof structure needs to be further improved. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Example:

[0027] Reference Figure 1-Figure 4 , a ash conveying pipeline feeding device for large storage equipment, comprising a silo body 1;

[0028] A silo roof 2 is fixedly connected to the silo body 1;

[0029] The material collector assembly 3 is fixedly connected to the silo top 2;

[0030] The conveying pipe 4 is fixedly connected to the material collector assembly 3;

[0031] The air supply pipe 6 is fixedly connected to the collector assembly 3 .

[0032] It should be noted that the silo body 1 is a grid structure composed of steel plates and vertical and circumferential ribs, and the silo roof 2 is a lattice shell structure composed of steel plates and trusses or grid structures.

[0033] It should also be noted that the delivery pipe 4 is connected to an external pneumatic delivery pump, and the air supply pipe 6 is connected to an air compressor or an air storage tank.

[0034] The collector assembly 3 includes a shell 302 , a fluidizing rod 301 and a discharge pipe 303 . The discharge pipe 303 is fixedly connected to the shell 302 , and the discharge pipe 303 is fixedly connected to the silo top 2 . The air supply pipe 6 is connected to the fluidizing rod 301 .

[0035] Reference Figure 1 , Figure 2 During the ash delivery process, the delivery pipe 4 delivers the fly ash to the shell 302. The fly ash delivered to the shell 302 will slide along the inner wall of the shell 302, and finally enter the bin body 1 through the discharge pipe 303 at the bottom of the shell 302, thereby completing the ash collection operation.

[0036] Reference Figure 4 , through the fluidizing rod 301 set on the shell 302, when in use, the second valve 7 is opened, and the air transported by the air supply pipe 6 will be transported along the air supply pipe 6, and finally sprayed out through the fluidizing rod 301. The gas sprayed by the fluidizing rod 301 can blow and turn the material transported to the shell 302, and then can homogenize the material, enhance the fluidity of the material in the shell 302, and improve the powder delivery efficiency.

[0037] The delivery pipe 4 is connected to a first valve 5 .

[0038] The air supply pipe 6 is connected to a second valve 7 .

[0039] The first valve 5 and the second valve 7 are solenoid valves or pneumatic valves available on the market.

[0040] It should be noted that the first valve 5 and the second valve 7 are both connected to the control room via communication cables. The specific control technology may adopt wireless communication control, and this application does not elaborate on this control technology.

[0041] The housing 302 is an arc-shaped shell.

[0042] Reference Figure 4 By setting the shell 302 as an arc-shaped shell, it is more conducive to the sliding of the coal ash into the warehouse, thereby improving the ash collection effect and efficiency.

[0043] The coal ash is collected by the device, which reduces the possibility of unsafe structure of the silo roof 2 caused by the large area occupied by the pipeline feeding above the silo roof 2 and the large number of openings, and realizes the centralized and convenient operation of the central feeding and pipeline feeding of the silo roof 2. At the same time, in the ash collection process, the speed of material entering the silo can also be reduced by the air supply pipe 6 and the fluidizing rod 301, thereby reducing the wear on the silo body 1 and extending the service life of the silo body 1.

[0044] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
