Control method of mixing and conveying device for civil engineering

Abstract

The invention provides a control method of a mixing and conveying device for civil engineering. The control method specifically adopts a mode of combining a pipe belt conveyor and a spiral conveyor to realize lifting and conveying of silt materials in civil engineering operation, and is matched with a flow monitor to realize comparison of front and back flows, the positive rotating speed and the negative rotating speed of the spiral conveyor are controlled to avoid material accumulation, and therefore, the problem that the pipe belt conveyor cannot convey the materials in the direction of a high inclination angle is solved.

Description

technical field [0001] The invention relates to a control method of a conveying device in civil engineering, in particular to a control method of a mixed conveying device for civil engineering. Background technique [0002] In the prior art, round pipe conveyors are often used in civil engineering operations to transport various excavated sediments. Since they can be set up in a closed conveying mode by using ordinary conveyor belts, they are dust-proof, Factors such as conveying speed are widely used. In order to meet conveying operations at different heights, it is often set up as a zigzag conveying mechanism for lifting and conveying operations in civil operations. However, in specific applications, its lifting angle exists. To a certain limit, the highest lifting angle is often set at about 30°. If the angle is too large, it cannot be effectively lifted, which will cause the sediment material to accumulate at the starting position of the lifting end of the Z-shaped struc...

[0002] In the prior art, the circular pipe conveyor is often used in civil engineering operations to transport various excavated silt. Since it can be set as an airtight conveying method by using an ordinary conveyor belt, it is dust-proof, Factors such as conveying speed have been widely used. In order to meet the conveying operations at different heights, it is often set up as a Z-shaped conveying mechanism for lifting and conveying operations in civil engineering operations. However, in specific applications, the lifting angle may vary. Within a certain limit, the highest lifting angle is often set at about 30°. If the angle is too large, it cannot be effectively lifted, and the sediment material will accumulate at the starting position of the lifting end of the Z-shaped structure, causing the material to break through the circular pipe conveyor. The seal of the material will spill outside; similarly, when the material is conveyed from the high position to the low position during the two-way transportation, the material will also accumulate at the starting position of the lifting end of the Z-shaped structure due to gravity, which will also cause damage and cannot Realize effective conveying. For the screw conveyor, although it can realize the maximum lifting in the vertical direction, however, due to its special structure and cost considerations, it is difficult to realize long-distance conveying
