Description
Technical field
This utility model belongs to wind-force and inhales the flow automatic control technology of sand, particularly relates to a kind of wind-force and inhales sand flow amount
Control structure, when multiple wind-force suction sand flow control structure is arranged on a wind-force sand suction pipe road, can be to one
The sand stream amount of bar wind-force sand suction pipe road multiple spot material feeding automatically controls, and multiple wind-force inhales sand flow-control knot
When structure is arranged on the wind-force sand suction pipe road that a plurality of combination is installed, large-area multiple spot wind-force can be realized further and return
Receive sand material.
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.
