Description

Automatic batching device for powder bulk truck and its application method

technical field

The invention relates to an automatic batching device for a powder bulk vehicle and a use method thereof, which is particularly suitable for fully mixing a small amount of powder batching with a large amount of powder.

Background technique

Bulk powder materials such as cement, fly ash, slag powder, steel slag powder, gypsum powder, lime powder, etc. are generally stored in cylindrical powder silos and transported by powder bulk trucks. The powder material loading method is generally from the cone-shaped outlet at the bottom of the cylindrical powder silo, or put it directly into the bulk truck, or put it into the bulk truck through a screw reamer, and then transfer it to the place where the powder is used, and then transport it to the bulk truck through pneumatic conveying. The powder is unloaded to the storage bin. Many powder materials need to be mixed with a small amount of other powder materials before use. Generally, they need to be produced or processed by equipment such as mixers. During this period, they need to go through steps such as metering, transportation, mixing, lifting, and storage. It is also necessary to use a dust collection device to solve the dust problem generated during production and processing.

In the process of transferring powder in this way, the powder material being transferred undergoes three violent fluidization movements. The first time occurs when the powder enters the bulk vehicle from the powder silo. The outlet position of the large powder silo is usually higher, and the bulk vehicle can be driven under the silo so that the discharge port is aligned with the bulk vehicle connection. Material port, after opening the door, use the weight of the powder to complete the loading. Generally, before opening the warehouse, blow compressed gas into the warehouse from the vicinity of the conical outlet of the warehouse to prevent the warehouse mouth from "arching" and prevent the material from being unloaded. High fluidity is produced during the loading process, so that the powder will rush into the bulk truck at a high speed after opening the warehouse, and the loading can be completed as soon as possible. It is conceivable that the powder will generate violent fluidization movement in the bulk vehicle. Of course, during this period, a large amount of dust will be generated and an instantaneous high air pressure will be formed in the bulk vehicle. These problems can be solved by the "vehicle bulk head" specially equipped for powder bin unloading. Exhaust dust collector. The second and third times occurred when the powder material was transported from the bulk vehicle to the storage bin at the place of use, because the powder bulk vehicle mostly uses pneumatic conveying, and the vehicle-mounted air compressor is used to transport the powder from the bulk warehouse on the vehicle before conveying the material. At the same time, multiple parts, such as the bottom and side of the tank, blow high-pressure gas into the closed bulk vehicle compartment to make the powder in the compartment "boil" and fluidize, and at the same time generate a certain pressure in the compartment, and then open the compartment. powder export. In this way, the powder in the bulk vehicle can be transported to the high feed inlet of the storage bin by using air pressure and pipelines, so that the unloading process of the bulk vehicle can be completed quickly and efficiently. It can be seen that the powder has undergone two violent movements before and after leaving the bulk truck. First, it is fluidized by high-pressure gas in the truck, and then it is blown into the storage bin and then highly dispersed and spread from the top of the bin to the bottom of the bin.

Therefore, by using the three violent fluidization movements that the powder materials naturally experience during the transfer process, the full mixing of different powder materials can be achieved, and the effect, that is, the uniformity of mixing is even much higher than that of the special mixing process. . This patented product is based on this principle, and a kind of automatic batching device for powder bulk truck is designed.
