Abstract
The utility model provides an anti-blocking pneumatic ash-delivery bend. The lower portion of an ascending section of the ash-delivery bend is slantly connected with a blocking clearing air pipe which is connected with an air source through an air quantity control valve. The air quantity in the ascending section can be increased due to the fact that the blocking clearing air pipe is added, thereby guaranteeing materials to pass through the ascending section under constant speed or accelerated speed, and avoiding blocking caused by deceleration and deposition of the materials. Once the ash-delivery bend is blocked because of sundries, stopping of air feeding and the like, users can use a pulse method to start the air quantity control valve to dredge the bend, and production is recovered rapidly.
Description
Technical field
The utility model belongs to the line transportation field, particularly a kind of pneumatic defeated grey elbow of anti-plugging that is used to carry dry bulk materials.
Background technique
The pneumatic conveying of pipeline is in field extensive uses such as power plant, cement, iron and steel.When pneumatic conveying bulk material, because defeated place's resistance of grey elbow ascent stage increases, mass transport speed slows down, and material gathers the back resistance and further strengthens, and therefore the elbow blocking phenomenon often occurs, and the dirt ash can't smooth and easyly be seen off, causes system's stopping production accident.Therefore need the pipeline tapping block clearing, resume production after the shutoff again.The time of not only clearing up obstruction is long, and labor intensity is big; And during artificial mediation elbow, the airborne dust that causes has a strong impact on operating environment.In addition, the defeated grey elbow rough surface after the recovery, the resistance increase more is prone to stop up.
Existing another mediation stemming method is to use the suction tank car.Be that ash conveying pipe stops defeated ash, the defeated ash of dismounting connects sebific duct.Connecting the suction tank car provides the suction sucking-off stifled ash.Shortcoming is to guarantee enough suction mediations, and also causing simultaneously to produce pause and purchase car increases expense.
Summary of the invention
It is a kind of simple in structure that the purpose of the utility model is to provide, and can prevent effectively that the elbow is stopped up in the defeated grey process, and the pneumatic defeated grey elbow of anti-plugging with block clearing function.
The solution that the utility model is taked is:
The pneumatic defeated grey elbow of a kind of anti-plugging is characterized in that, at the oblique connection one block clearing airduct in bottom of defeated grey elbow ascent stage, the block clearing airduct is connected with wind regime through the volume control damper door.
The axis of said block clearing airduct and the angle between the vertical line
βIt is 15 °～35 °.
The diameter of said block clearing airduct is 1/4～1/3 of defeated grey elbow diameter.
The beneficial effect of the utility model is:
1, owing to be provided with the block clearing airduct in the bottom of elbow ascent stage, can increase the air quantity of ascent stage, guarantee that material at the uniform velocity or quicken through the ascent stage, has prevented that material reduction of speed deposition from resulting in blockage.
When 2, in a single day causing defeated grey elbow to stop up because of reasons such as blowing-out, foreign material, the method for volume control damper door is started in pulse capable of using, and the mediation elbow resumes production fast.
Description of drawings
Accompanying drawing is the pneumatic defeated grey elbow structure schematic representation of anti-plugging.
Among the figure: wearing layer 1, elbow ascent stage 2, bend horizontal section 3, block clearing airduct 4, volume control damper door 5.
βAngle between expression block clearing airduct axis and the vertical line.
Embodiment
Visible by accompanying drawing; Pneumatic defeated grey elbow comprises elbow ascent stage 2, bend horizontal section 3 two-part, elbow ascent stage 2 and bend horizontal section 3 intersect vertical axis, on defeated grey elbow bending circular arc, is provided with wearing layer 1; In order to the wear resistance at the bottom of the increase elbow arc, prolong the working life of elbow.
At first, choose the specification of block clearing airduct 4 in the ratio of defeated grey elbow diameter 1/4; Again by the circular arc portion perforate of block clearing airduct 4 diameter dimensions in the bottom of elbow ascent stage 2; One section block clearing airduct 4 of oblique welding in perforate then, direction are that block clearing airduct 4 the other ends tilt to bend horizontal section 3 directions, and the axis of block clearing airduct 4 and bend horizontal section 3 axes intersect, angle between block clearing airduct 4 axis and the vertical line
βIt is 25 °.At last, on block clearing airduct 4, install volume control damper door 5 and fixture, again with volume control damper door 5 with can come into operation after wind regime is connected.
Claims (3)
1. the pneumatic defeated grey elbow of anti-plugging is characterized in that, at the oblique connection one block clearing airduct in bottom of defeated grey elbow ascent stage, the block clearing airduct is connected with wind regime through the volume control damper door.
2. the pneumatic defeated grey elbow of anti-plugging according to claim 1 is characterized in that the axis of said block clearing airduct and the angle between the vertical line
βIt is 15 °～35 °.
3. the pneumatic defeated grey elbow of anti-plugging according to claim 1 is characterized in that, the diameter of said block clearing airduct is 1/4～1/3 of defeated grey elbow diameter.
