AI Technical Summary
When unloading, the existing powder truck has many dead corners in the breathable cloth fluidized bed structure, and the powder accumulation cannot be completely discharged. In addition, the unloading method is single and it is impossible to switch between pressure unloading and gravity unloading.
The powder truck adopts an annular direct-blowing fluidization device, which is connected to the gas supply device through the air inlet. The gas enters the gas bin and is blown into the internal cone from the air holes of the fluidizing ring to completely fluidize the powder. Combined with the design of the discharge valve and the sewage valve, the complete discharge of the powder and the pressure-free unloading of the granular material are achieved.
The powder is discharged in a completely fluidized state, which reduces the residual material rate. It can also clean the inside of the gas bin without disassembling parts, and provides flexible options for pressure unloading and gravity unloading.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of powder and particle material transport semi-trailers, in particular to an annular direct-blowing fluidization device for a powder material transport vehicle. Background Art
[0002] Powder trucks are suitable for transporting solid powders and granular goods such as fly ash, cement, lime powder, ore powder, and grain. Powder trucks effectively reduce dust, save packaging materials, and reduce loading and unloading labor. They are widely used in cement plants, cement warehouses, and large construction sites.
[0003] However, when unloading, the existing powder trucks need the powder to be in a completely fluidized state so that the powder can be discharged from the tank along with the gas. The commonly used breathable cloth fluidized bed structure has many dead corners, causing powder accumulation, making it impossible to completely discharge and difficult to clean, which increases the residual rate of the material.
[0004] Another original discharge port is a valve, which cannot realize pressure unloading and gravity unloading. In response to the above problems, the inventor proposed a powder truck annular direct blowing fluidization device to solve the above problems. Utility Model Content
[0005] In order to solve the problem that the air-permeable cloth fluidized bed structure has many dead corners, resulting in powder accumulation and inability to be completely discharged, the purpose of the utility model is to provide a powder vehicle annular direct-blowing fluidization device.

The air device facilitates the external air to enter the air bin through the air inlet, and then blows it into the inner cone from the air vents in the fluidizing ring and blows it towards the powder in the inner cone. At the same time, the air inlet can inflate and pressurize the tank body, so that the powder is in a completely fluidized state. Then, the discharge valve 1 is opened, so that the powder passes through the discharge pipe with the gas and is discharged from the discharge pipe, thereby achieving a fluidized state of the powder, thereby reducing the accumulation of the powder, enabling it to be completely discharged, and reducing the residual rate of the material. When too much powder is accumulated in the air bin, air is inflated through the air inlet, and then the drain valve is opened to force the powder to be discharged through the drain valve, thereby achieving the cleaning of the air bin without disassembling parts.
[0007] During the unloading process of the granular material, the discharge valve 2 is opened so that the granular material flows directly to the conveyor belt of the pit, realizing pressure-free unloading.
[0008] Preferably, an air inlet is fixedly provided on the outer surface of the external funnel, and a sewage valve is fixedly provided on the outer surface of the external funnel.
[0009] Preferably, a second discharge valve is installed on the outer surface of the discharge pipe, a first discharge valve is installed on the outer surface of the discharge pipe, the external funnel and the discharge pipe are interconnected, and the discharge pipe and the discharge pipe are interconnected.
