Description

Cement container capable of being integrally assembled and disassembled and transportation method thereof

Technical Field

The invention belongs to a cement transportation method, and particularly relates to a cement container capable of being integrally assembled and disassembled.

Background

Bulk cement means that after the cement is produced from the factory, it is transported directly from the factory to a transfer station or to the hand of a user without any small packages, by means of special equipment or containers. After the cement leaves the factory, the manufacturer can not know the cement transportation route and the position.

The bulk cement loading mode includes movable negative pressure sucking, unpacking and loading, lifting, unloading, moving, transporting, loading, unloading, transporting, loading or storing.

As shown in fig. 6, a process flow diagram of the existing mobile negative pressure suction unpacking and loading is shown. The method comprises the following steps: the material is directly taken from a container on a collecting card by a manual operation suction nozzle by utilizing the principle of negative pressure suction, the material is sucked into a separator of a suction unit (comprising a vacuum pump, an air compressor, an integrated electric control cabinet and the like, and the like) through a hose, the material is discharged into a bulk head (comprising an embedded dust removing device, and the like) through a gas locking and discharging device at the bottom of the separator after being separated by the material gas, the material is dustless filled into a bulk cement transport vehicle, and the purified gas is discharged into the atmosphere through the vacuum pump.

As shown in fig. 7, a process flow diagram of a conventional lifting inverted box mobile mechanical conveying loading is shown. The method comprises the following steps: the container door is opened, the container dumper is lifted slowly, the materials in the container are unloaded into the feed hopper, the inclined conveyor continuously conveys the materials to the head of the inclined conveyor and carries the materials through the bulk head in a dust-free manner, and the dust raised in the unpacking process is controlled by the dust remover to be collected in the dust-proof telescopic awning and then discharged into the conveyor to be taken away. The inclined conveyor may be a screw conveyor, a buried scraper conveyor, a bucket conveyor, a corrugated flange belt conveyor, or the like.

As shown in fig. 8, a process flow diagram of the unloading machine inverted box fixed mechanical conveying loading or warehousing is provided. The method comprises the following steps: the truck is opened to the appointed position of the platform of the unloader, the unloader lifts up the wheel stopper to fix the truck, the container door is opened, the unloader lifts up slowly, the materials in the container are unloaded into the feed hopper, the follow-up conveying equipment conveys the materials to the storage warehouse or the bulk head in a dust-free loading manner, the dust lifted up in the unpacking process is controlled in the fixed dust collection cover and the follow-up dust collection cover by the dust remover, and the dust is discharged into the conveyor to be taken away. The subsequent conveying equipment which is in butt joint with the underground receiving belt conveyor can be an inclined spiral conveyor, a buried scraper conveyor, a belt conveyor, a lifter and the like.

Therefore, the short plates of various links such as multiple cement transportation links, opacity, rough operation and the like lead to high cost, low efficiency, large pollution and large labor intensity, and severely restrict the further development of the cement 'bulk change set'. At present, the policy level is very important to the multi-mode intermodal transportation of containers, but the actual operation lacks a long-acting and smooth cross-department cooperation mechanism, so that the connection between different transportation modes has certain difficulty. The transportation service, in particular to the multi-mode intermodal 'one-stop' integrated service, has narrow coverage, and the operation mode of 'one-to-one, information sharing and supervision common management' has the influence on the goods in-transit time in popularization.
