High-efficient and environment-friendly transferring and unloading method for powder and powder container used for same

Abstract

The invention discloses a high-efficient and environment-friendly transferring and unloading method for powder and a powder container used for the same. The method and the powder container aim to overcome the defects that in the prior art, bulk transfer of powder is high in manufacturing cost, conveying efficiency is low, energy consumption and unloading cost are high, potential safety hazards exist, an amount of dust is leaked outside, and the environment is polluted. The powder container which is flexible, waterproof and foldable is arranged on a means of transport, powder is loaded into the powder container and transported to the destination, and the powder is sucked out from the powder container under a negative pressure condition and transported to a powder field of the destination or a material warehouse of the destination. The powder container is provided with a flexible and waterproof material wall capable of being folded, and the flexible and waterproof material wall is provided with a powder channel and an exhaust mechanism. The powder container is mainly used for storing, transferring and conveying the powder such as cement and pulverized fuel ash, the powder container can be folded so that the size of the powder container can be reduced, the environment protection property and safety are good, the manufacturing cost is reduced by more than 70%, energy is saved by more than 15%, transferring cost is lowered by more than 40%, efficiency and benefits are improved by more than 20%, and floating dust is reduced by more than 10%.

Description

Technical field [0001] The invention relates to a powder transfer and unloading method and a used appliance, in particular to an efficient and environmentally friendly powder transfer and unloading method and a used powder container. Background technique [0002] Existing bulk powder transfer devices include trains, automobile powder hopper tankers, open-ended hoppers, such as train bulk powder hopper trucks, automobile bulk cement tankers, fly ash transfer hoppers, etc. These transfer devices are expensive After being transported to the destination, the vehicles must be returned empty-loaded one by one, which wastes resources and fuel and makes the transport cost high; when unloading, high-pressure air is introduced into the tank to increase the pressure in the tank, and the tank The powder is pressed out of the tank and transported to the storage device at the destination through a conveying pipe. This positive pressure discharging and conveying device and method has high cost,...

AI Technical Summary

Problems solved by technology

[0002] Existing devices for transferring powder in bulk include trains, automobile powder tank cars, open car bodies, etc., such as train bulk powder tank cars, automobile bulk cement tank cars, fly ash transfer car bodies, etc. These transfer devices are expensive , after being transported to the destination, it is necessary to return empty vehicles and loads one by one, which wastes resources and fuel and makes the cost of transshipment high; The powder is pressed out of the tank and transported to the storage device at the destination through the conveying pipe. This device and method of positive pressure discharge conveying has high cost, low conveying efficiency, high energy consumption, high unloading cost, and potential safety hazards. ; And the transport of the transfer car body is not conducive to waterproofing, it is dumped at one time when unloading, the dust is large, and the environment is polluted
