Dual-system material-smoothening automatic-balancing regulating control device and method

Abstract

The invention relates to the field of bulk cargo conveying of belt conveyor, in particular to a conveying material-smoothening control device and method of a belt conveyor. A dual-system material-smoothening automatic-balancing regulating control device comprises a moving trolley, a trolley track, a track fixing frame, a trolley traveling motor, a moving chute, a dual-system left chute, a dual-system right chute and an electronic scale. A dual-system material-smoothening automatic-balancing regulating control method comprises the steps that a unit displacement distance, a test time interval and a deviation threshold value of the moving chute are set, the electronic scale measures the flow of material on a dual-system downstream belt conveyer every other test time interval, and if deviation of the left material flow and the right material flow of the dual-system downstream belt conveyer is greater than the deviation threshold value, the moving chute moves towards the side with the lower material flow. The dual-system material-smoothening automatic-balancing regulating control device and method ensure that the locating point of the moving chute is in a dual-system material-smoothening balancing state all the time, avoid material leakage and accumulation accidents caused by flow deviation of the moving chute, guarantee that a conveying belt operates normally, and facilitate safety production and productivity improvement.

Description

technical field [0001] The invention relates to the field of bulk material conveying by belt conveyors, in particular to a material conveying control device and method for belt conveyors. Background technique [0002] The mobile chute is a device used for dual-system distribution of materials conveyed by the upstream belt conveyor. The material distribution method of the mobile chute is to adjust the feed distribution of the chute entering the downstream dual-system belt conveyor through the position of the mobile trolley, so as to achieve the purpose of dual-system feed balance. [0003] Due to material accumulation and liner wear in the downstream belt conveyor chute of the dual-system material distribution process, the material distribution in the mobile chute is uneven, and the effect of the downstream belt conveyor is reduced. The dual-system material distribution deviation caused by Unbalanced material delivery and accidents such as material spreading and pressing of ...

AI Technical Summary

Problems solved by technology

[0005] 1) When the moving chute is blocked and the material enters one side, when the belt conveyor on one side exceeds the system setting table, the belt conveyor on one side will stop due to overload and stop, while the other side will run without load;

[0006] 2) The moving chute is partially blocked and the material is unbalanced on both sides, and the effect of the belt conveyor on the side where the system flow rate is too high decreases, which affects the system's operating time.

[0007] 3) The material on both sides of the moving chute is unbalanced, causing accidents such as material spreading and pressing on one side of the belt conveyor

[0015] At present, due to the lack of automatic control and adjustment functions in the implementation of the above two methods, coupled with the negligence of operators, it is often impossible to find out the material deviation of the two sides of the system in time; the belt conveyor is basically a closed device (the belt conveyor has an organic cover), It is relatively difficult for on-site personnel to visually observe the material deviation of the dual-system feeding; to observe the balance of material distribution on both sides of the system with the naked eye and the control room, the operator needs to be highly concentrated and has a high labor load; the on-site operators often adjust the flow on both sides. Misjudgment not only affects the operation efficiency, but also has high labor intensity

Sometimes, although the materials on both sides are relatively balanced, the system time cannot meet the design requirements and cannot meet the requirements of the crushing and screening operation of fine lump ore blast furnaces

Therefore, there is no practical and effective solution to the adjustment of the moving chute of the belt conveyor.
