Description
Technical field
The invention belongs to wind-force and inhale the flow automatic control technology of sand, particularly relate to a kind of wind-force and inhale sand flow-control
Method.
Background technology
Pipeline wind model is a kind of efficient, practical, easy mode of movement.Particularly pipeline wind model sand
Pipe material inhales sand, owing to it has simple in construction, is easily installed and the advantage such as use, currently extensively should
With.
During pipeline wind model sand material, in order to guarantee to carry sand continuously in wind-force sand suction pipe road
Material, needs the flow that sand material enters pipeline to be adjusted, if sand material and conveying tolerance ratio are improper, holds very much
Easily cause sand material blocking pipeline.
At present, it is usually and uses mechanical flow adjusting device that the flow of sand material is adjusted, but, this
There is following defect in regulative mode:
(1) use mechanical flow adjusting device that the flow of sand material is adjusted, regulation operation and use the most side
Just.
(2) limited by on-site actual situations, if the concrete structure in wind-force sand suction pipe road does not allow to arrange mechanical flow
Adjusting means, then will result in in-site installation difficulty so that this regulative mode is difficult to really implement.
(3) the control of sand stream amount is required higher by the wind model sand material system of large area multiple spot material feeding, if regulation
The most improper, sand material easily blocks pipeline.
(4) the transfer efficiency of wind model sand material is the most relatively low, to improve transfer efficiency, avoiding line clogging,
Existing method is to increase diameter and the air quantity in wind-force sand suction pipe road, improves blast simultaneously, and its essence increases merit exactly
Rate, this will cause wind model system to consume energy very much, substantially increase production cost, it is difficult to large area multiple spot
The system of material feeding carries out promoting and actual application.
Summary of the invention
It is an object of the invention to provide a kind of simple, use cost is low, less energy consumption, simple to operate, use
Conveniently, reliably the wind-force that sand material carries continuously, transfer efficiency is high, be applicable to various wind-force suction sand occasion, is guaranteed
Inhaling sand flow amount control method, when being applicable to large area, multiple spot and automatically collecting sand material, its technique effect is the most aobvious
Write.
The purpose of the present invention is realized by following technical measures: a kind of wind-force inhales sand flow amount control method, and it is special
Levy and be: in the wind-force sand suction pipe road of level and the receiving opening that is right against on wind-force sand suction pipe road end face makes from being subject to
The sand material that material mouth enters forms natural packing state, and enters wind-force by the accumulation angle of repose control sand material of sand material
The flow in sand suction pipe road, and then realize sand stream amount in wind-force sand suction pipe road is automatically controlled.
Accumulation angle of repose refers to: bulk cargo is fallen on horizontal plate continuously from funnel, is piled into cone, the mother of cone
Angle between line same level face is referred to as piling up angle of repose, and it is to keep natural stability shape when bulk cargo is piled up
The maximum angle of state.
The present invention utilizes the physical state piling up angle of repose of sand material, realizes automatically controlling sand stream amount,
