Problems solved by technology

However, the discharge ports of the existing large-scale fluidized storage are all set in the discharge corridor, which is not easy to check. Once the flow control device is damaged, it will be difficult to block the large flow of materials in the storage, and it is easy to block and bury the discharge corridor. Material conveying equipment, causing great economic losses, especially when there are people in the unloading corridor, may also cause casualties, so there are certain safety hazards

Embodiment 1

[0030] Such as figure 1 and figure 2 The floor-standing powder storage of the present invention includes a top 1, a wall 2, a bottom 3 and a foundation 4, and the top 1, wall 2, bottom 3 and foundation 4 are all made of reinforced concrete. When building the warehouse, the warehouse bottom 3 is directly set on the land 8, and the warehouse bottom 3 and the warehouse foundation 4 are integrated. The bottom of the storehouse 3 is provided with a material flow aid device 27, the material flow aid device is composed of a pneumatic fluidization rod, and the pneumatic fluidization rod is connected with an air supply pipeline, and the air supply pipeline includes a main air supply pipeline 10, and the main air supply pipeline 10 The branch gas supply pipeline 11 communicates with the pneumatic fluidization rod, and the branch gas supply pipeline 11 is provided with a valve 26 to control the passing gas volume and air pressure. In addition, the floor-type powder storage of the pres...

Embodiment 2

[0036] Such as Figure 6 , Figure 7 and Figure 8 The difference between the shown floor-standing powder storage of the present invention and Embodiment 1 is that the top 1, the wall 2, and the bottom 3 are made of steel, and the foundation 4 is made of reinforced concrete. Wall 2 is welded into one. The reclaiming device 5 is provided with seven, and the decompression chamber 7 is fixedly arranged on the material conveying pipe 14 in the reclaiming device 5. The decompression chamber is positioned at the top of the discharge port 15. The decompression chamber includes a decompression chamber body 18, and the decompression chamber includes a decompression chamber body 18. The side wall of the bin body 18 is provided with a feed opening 19 , and the pneumatic fluidization rod constituting the material flow aid device 27 partially extends below the decompression bin 7 . In addition, an enclosure 17 is also provided around the material feeding port 15 of the material conveyin...

Embodiment 3

[0040] Such as Figure 6 , Figure 7 , Figure 9 and Figure 10 The difference between the floor-standing powder storage of the present invention and the second embodiment is that, in order to meet the needs of long-distance horizontal feeding, in addition to increasing the number of discharge ports 15 provided on the material delivery pipe 14 in the reclaiming device 5, Corresponding to the blanking port 15 , the material conveying pipe 14 is also provided with a forward deflector 25 , and the forward deflector 25 is gradually inclined downward along the discharge direction of the material conveying pipe 14 . In addition, if Figure 9 As shown, the inner diameter of the chamber surrounded by the air-permeable cloth 23 in the pneumatic fluidization rod 16 is larger than the outer diameter of the steel pipe 21 .

[0041] Compared with Embodiment 2, in the floor-standing powder storage warehouse described in this example, due to the addition of a forward deflector 25 at the ...

Abstract

The invention relates to a floor type powdery material storehouse which comprises a storehouse top, storehouse walls, a storehouse bottom and a storehouse foundation, wherein material flowing assisting devices are arranged on the storehouse bottom and are composed of pneumatic fluidization rods which are connected with air supply pipelines, material falling openings are formed in material conveying pipes, a decompression cabin is arranged on each material falling opening of the material conveying pipes, the side wall of each decompression cabin is provided with a feeding notch, the pneumatic fluidization rods are arranged in the material conveying pipes, the material conveying pipes are horizontally arranged on the surface of the storehouse bottom and penetrate through the bottoms of the storehouse walls and extend out of the storehouse, a material flow control device is arranged at a discharge end, located outside each storehouse wall, of each material conveying pipe, the other end, located inside the storehouse, of each material conveying pipe is an air supply end, and the air supply end of each material conveying pipe is connected with an air supply pipeline. In addition, barriers can be arranged on the periphery of each material falling opening of the material conveying pipes. The floor type powdery material storehouse is simple in structure and good in economy and safety performance, and can be widely applied to storage of powdery materials such as coal ash and cement.

Description

technical field [0001] The invention relates to the field of storage equipment, in particular to a floor storage for storing powdery materials. Background technique [0002] At present, floor-standing large-scale fluidized storages are mainly divided into two types: concrete silos and steel plate silos. The silo is cylindrical in shape and has the characteristics of large storage capacity and good stability. It is widely used in building materials, grain and chemical raw materials, etc. Storage of powdery or solid materials. Existing large-scale fluidized storage mainly relies on the discharge port at the bottom of the storage to discharge materials, and the corresponding discharge corridor is set at the bottom of the storage to lead to the outside of the storage to accommodate material conveying equipment and provide maintenance space. In order to ensure the rate of material out of the warehouse, it is usually necessary to set up multiple discharge ports, and the multiple ...
