Wet Material Unloading Method for Large Bulk Cargo Terminal Ship Unloader

Abstract

The invention provides a method for unloading wet material from a ship unloader at a large bulk cargo terminal, comprising the following steps: S1, controlling the grab to grab the wet material from the silo, and the grab grabs the wet material and then stays above the hopper; S2, slowly Quickly open the grab bucket, and the wet material in the grab bucket slowly flows out into the hopper; S3, after the wet material in the grab bucket reaches the preset time, close the grab bucket until the wet material in the hopper is completely discharged; S4, repeat steps S2 and S3 , until the wet material in the grab is finished; S5, repeat steps S1 to S4, until the wet material in the silo is unloaded. The invention controls the running time and running mode of the grab bucket and the vibrating feeder, so that the internal parts of the ship unloader will not overflow and exceed the flow rate, and ensure the safe and efficient unloading of wet materials, which is conducive to the stability of the equipment run.

Description

technical field [0001] The invention relates to the field of ship unloader unloading, in particular to a wet material unloading method for a large bulk cargo terminal ship unloader. Background technique [0002] The ship unloader is a machine head that can lift bulk materials by using continuous conveying machinery, or has the ability to reclaim materials by itself, or is equipped with a retrieving and feeding device, continuously lifts the bulk materials out of the cabin, and then unloads them to the It is a special machine that can be transported to the main transport system on the shore with a jib or rack. The use of ship unloaders can greatly improve the unloading efficiency, and the minimum dust pollution can keep the environment clean, efficient and environmentally friendly. [0003] When the large-scale bulk cargo terminal is operated to the middle and lower parts, the mineral materials in the cabin gradually appear as muddy and irregular quagmire at the bottom of th...

AI Technical Summary

Problems solved by technology

[0004] The conventional operation method of the ship unloader at the bulk cargo terminal is to grab the material above the hopper through the semi-automatic circulation of the grab bucket and then open it. The conventional operation method for wet material operation has the following disadvantages: it is easy to cause a large amount of overflow and excessive flow in the ship unloader It is also not conducive to the stable and forward movement of the equipment; the unrestrained grabbing operation will also cause the pressing, slipping, deviation of the ground conveying system and the overflow of a large part of the wet material, causing the belt to scatter abnormally along the line

[0006] 1. Consequences of spillage: Abnormal scattering along the belt, serious waste of mineral materials, and pollution to the surrounding environment

[0007] 2. Equipment damage: the wet material in the hopper of the ship unloader is discharged concentratedly and destroys the steel frame structure inside the ship unloader

[0009] 4. Safety factor: There are potential safety hazards in the patrol inspection personnel in the machine
