Description
Technical field
The present invention relates to a kind of purging methods of powder transmission pipeline, for glass fibre manufacture industry transmission stone powder
Pipe flushing.
Background technique
In glass fibre manufacture industry, the stone exploited on mountain becomes flour, these substances after crushing
By some iron or steel pipelines, under the action of pressure-air, it is transported in kiln and carries out high temperature incineration, melts, then
The stone powder of thawing is drawn into glass fibre by some special equipment.In actual operation, the stone powder of crushing is not
It always is dry, quite a few is that moist, moist stone powder transmits in pipeline, because of the gas of pressure-air
Source pressure is typically all constant pressure, and the transmission process of stone powder can be more stable, and pipeline will not vibrate, and one is in pipeline
A more stable state, under such environment, stone powder will be attached on the inner wall of pipeline gradually over time, more attached
It is more, so that transmission pipeline aperture is constantly attenuated, until line clogging, pipeline is scrapped, and influences the raw material supply of kiln, in turn
Influence production.
Summary of the invention
In order to which the stone powder for solving moist transmits in pipeline, the case where being liable to stick on tube wall, and then block pipeline,
The present invention provides a kind of purging methods of powder transmission pipeline, by the invention it is possible to prevent the attached of powder in production
, when there is congestion, certain removing attachment can be played the role of, thus the case where avoiding line clogging generation.
The present invention is to solve technical solution used by its technical problem: in the starting point of transmission pipeline close to lime
Cang Xialiaokouchu welds several segments flushing pipe, and on-off valve is provided on flushing pipe and gas source is rinsed in other end connection, is passed through
The on-off of on-off valve controls opening and closing for flushing pipe, and flushing pipe, which is divided into, to be rinsed main pipeline and rinse auxiliary pipeline, flushing pipe
The erection sequence in road is as follows, rinses main pipeline and transmission pipeline structure at an angle, referred to as X angle, is to rinse main pipeline
Point, along the transmission direction of transmission pipeline, auxiliary pipeline 1 is rinsed in setting at a certain distance from from main pipeline is rinsed, and rinses auxiliary pipeline 1
At an angle with transmission pipeline structure, referred to as Y angle, Y angle is less than 90 degree and the sum of X angle and Y angle is less than 270 degree,
Auxiliary pipeline 2 is rinsed from setting with a certain distance from auxiliary pipeline 1 is rinsed, auxiliary pipeline 2 is rinsed with transmission pipeline and equally constitutes an angle,
Also it is Y angle, according to the length of transmission pipeline, sets gradually several angles constituted with transmission pipeline at a certain distance respectively
Also be the auxiliary pipeline of flushing of Y angle, be set as N number of, rinse gas source bleed pressure be 2 times of compressed air gas source pressure or with
On, the on-off valve for rinsing main pipeline and rinsing above auxiliary pipeline is connected on controller, and controller is connected with input unit, such as presses
Button or touch screen etc., purging method of the invention are divided into service mode and cleaning mode, and both of which can pass through input unit
It switches over, when normal use, is set as service mode, rinse main pipeline and close, rinse auxiliary pipeline and open, to make for daily
Used time maintenance, prevents line clogging, when transmission pipeline has stopping state, is set as cleaning mode, opens rinse auxiliary pipe at this time
Road 1 allows the gas for rinsing gas source to enter transmission pipeline, after certain interval of time, if the time is T1, closes and rinses auxiliary pipeline 1,
It opens simultaneously and rinses auxiliary pipeline 2, after interval time T1, close and rinse auxiliary pipeline 2, open simultaneously and rinse auxiliary pipeline 3, according to this class
It pushes away, with same interval time T1, closes respectively and open auxiliary pipeline 4,5,6 of flushing etc., until n-th rinses auxiliary pipeline, when
When n-th rinses auxiliary pipeline opening, after interval time T1, closes n-th and rinses auxiliary pipeline, open simultaneously flushing main pipeline,
The time of opening is set as T2, and time interval T1 and T2 can be configured in the controller, and the time range of T1 1 second to 20
Between second, the time range of T2 is between 3 seconds to 30.
The principle of the present invention is: in the maintenance mode, by rinsing under the back flush effect of auxiliary pipeline, in transmission pipeline
Transmission process will not stablize, have sinuous flow generation, by the effect of sinuous flow, prevent powder to be attached on tube wall and cause congestion,
Under rinse mode, rinsing auxiliary pipeline by the opening being successively spaced makes pipeline generate vibration, the powder that will be attached on tube wall
Vibration is fallen, while rinsing the powder that vibration is fallen by rinsing main pipeline, to achieve the purpose that flushing pipe.
Detailed description of the invention
Fig. 1 is the installation diagram in the use of the present invention, scene.
Fig. 2 is to rinse main pipeline on transmission pipeline and rinse the installation detail view of auxiliary pipeline.
In figure, 1 is lime silo feed opening, and 2 be compressed air gas source, and 3 be transmission pipeline, and 4 be to be led with feed bin, 5 to rinse
Pipeline, 6 be that rinse auxiliary pipeline 1,7 be that rinse auxiliary pipeline 2,8 be that rinse auxiliary pipeline 3,9 be the auxiliary pipeline N of flushing, and 10 be X angle, 11
For Y angle.
Specific embodiment
In the starting point of transmission pipeline at lime silo feed opening, several segments flushing pipe is welded, is set on flushing pipe
It is equipped with on-off valve and gas source is rinsed in the connection of the flushing pipe other end, on-off valve can be solenoid valve or motor-driven valve, the arrow in Fig. 1
Head indicates that transmission pipeline transports the transporting direction of powder, opening and closing for flushing pipe is controlled by the on-off of on-off valve, rinses
Pipeline, which is divided into, to be rinsed main pipeline and rinses auxiliary pipeline, and the erection sequence of flushing pipe is as follows, rinses main pipeline and transmission pipeline structure
