Abstract
The utility model relates to a pipeline for pneumatically conveying materials. The pneumatical pipeline is fixed on the upper wall of a conveying pipeline by welding holes. The pneumatical pipeline is provided with uniformly distributed blowing holes on the lower wall of the pneumatical pipeline, which prevents the pipeline from clogging because of high pressure and keep materials from stacking up on the pipeline base because of low conveying airspeed when materials being conveyed in the pipeline. The pipeline utilizes the action of the blowing holes to enhance mixture strength and keep the pipeline from clogging. Whatever the powdery material is or long distance or short distance of conveying is the device can achieve the goal of conveying successfully, which saves a good deal of foreign exchange for China and makes air conveying equipment become a complete set and advanced.
Description
A kind of Pipeline for pneumatically conveying materials of convey materials.
At present, the strength convey materials mainly is made up of transmission pump and delivery duct two large divisions.It all is at the research transmission pump that there are a lot of units in past, develops into various forms of cone pumps by screw delivery pump, fluidization strength transmission pump.These are carried all is will be by delivery duct the place of mass transport to appointment.Therefore, Pipeline for pneumatically conveying materials can with the supporting use of various strength transmission pumps.When remote the conveying, mainly reconcile melting concn by transmission pump.The melting concn height, just the blocking pipe melting concn is low easily, and air consumption is many, and wind speed is too fast, and pipe wear is serious, wastes energy, and increases maintenance capacity, and influence is produced.
When material was carried in pipeline, if hypertonia will produce the close stream in the end, more near the pipe end, it was close more to distribute for particle, but does not occur stagnating, and some is rotated in the above, collided, and one side is transferred, and pressure has some fluctuation, and pipeline will stop up.
Most producer all is to use the air pipe network, pressure instability, this just carries to strength and causes difficulty, when air-transport system is worked, once other places wind, material will produce stagnation in pipeline, most material loses the ability of suspension, the material that is stuck in the pipe end is collected at together in some areas, makes the local stenosis of pipe section narrow, and therefore the air-flow velocity at this place increases, again the material of stagnating is being blown away in a flash down, material comes to this and stagnates aggregation, blows away, and alternate with each otherly is unsettled feed status, and pipe vibration is bigger.
When delivery air speed was too small, solid accumulation was at the pipe end, and air-flow flows on top, when air-flow increases, will produce plug flow, the material bed delivery duct that has been full of of accumulation, one section is material, one section is air-flow, and by the pressure promotion of air, pipeline will produce vibration and obstruction during convey materials.
The purpose of this utility model provides a kind of Pipeline for pneumatically conveying materials, it not only can improve mixing of materials concentration, no matter what granular material, carry at a distance or closely, under the injection hole effect, material can not stagnated aggregation and cause pipe vibration and obstruction in pipeline, solved the existing hard nut to crack of delivery duct for many years, this pipeline is succeeded in developing, and Pneumatic Conveying Technology is further developed.
The utility model is achieved in that Pipeline for pneumatically conveying materials comprises delivery duct, suspension air pipe, steam line, induction tract etc., the suspension air duct is fixed on the delivery duct by access hole, the delivery duct inlet is connected with the transmission pump outlet by flange (or welding), material enters delivery duct slowly from transmission pump, because external source of the gas enters in the suspension air duct, by its lower wall injection hole effect, make material remain suspended state, and deliver to order ground by outlet smoothly.
Advantage and good effect:
1, no matter be to carry central power failure suddenly or device fails to cause pipe choking, as long as fault handling finishes, starting Pipeline for pneumatically conveying materials, pipeline will be open-minded automatically, and material is carried out smoothly.
2, under the effect of air suspension pipe, the formed stagnation stream of the delivery duct of making over, group's stream, the close stream in the end, abnormal flowing such as plug flow thoroughly changes, and reaches suspension flow fully.The delivery duct vibration is very little.
3, in remote course of conveying, can improve melting concn 1-3 doubly.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof
The structure connection diagram of Fig. 1 Pipeline for pneumatically conveying materials
Fig. 2 lateral plan
Fig. 3 injection hole gradient enlarged drawing
Fig. 4 injection hole is developed and printed A to view
Be described in detail concrete structure of the present utility model and operational detail below in conjunction with accompanying drawing.
As shown in Figure 1: fixedly formed by access hole, (9) air communication pipe of suspension pipe by air inlet pipe, (6) shutoff valve, (7) steam line, (8) of the logical pipe that firmly suspends of (1) delivery duct, (2) injection hole, (3) suspension air pipe, (4) closure plate, (5) for Pipeline for pneumatically conveying materials.
Suspension air pipe (3) places in the delivery duct (1), be fixed on delivery duct (1) upper wall by access hole (8), weld with closure plate (4) at suspension air pipe (3) two ends, has air inlet pipe (5) at the one end towards the suspension pipe, be connected with steam line (7) by shutoff valve (6), suspension air pipe (3) lower wall have the rectangular distribution gradient be 10-15 °, diameter is the injection hole (2) of 2mm.
The calculating of the distance L 1 of suspension air pipe length L and injection hole
L＝L1 (d3)/(d)
L1＝（d1－d2）ctg15°
L-suspension air pipe length
L1-injection hole distance
The internal diameter of d1-delivery duct
D2-suspension air pipe external diameter
D3-suspension air pipe internal diameter
But the Pipeline for pneumatically conveying materials single-unit, also or more piece, for the Pipeline for pneumatically conveying materials that connects, the delivery duct of every joint Pipeline for pneumatically conveying materials (1) all is connected by air communication pipe (9) with suspension air pipe (3) more.
The diameter of suspension air pipe (3) is according to the diameter of delivery duct (1) and length and fixed, can select the steel pipe of φ 1/2 " 1 " for use, stayed 100 millimeters beginnings by an end, its distance is some injection holes (2) of 2 millimeters for L1 tilts 10 °-15 ° to be drilled to diameter in turn.The practice of injection hole (2) is: be washed into leg-of-mutton gravure 3 * 12 in fixing position with special-purpose punching pin earlier, gradient boring along gravure is 2 millimeters of φ, be injection hole (2), the two ends welding is blocked up, flow out 100 millimeters by an end, 100 millimeters high and air pipe diameter are mutually as air inlet pipe and connection pipe.
The assembling of suspension pipe
The hole of on delivery duct (1), opening an air inlet pipe earlier, then by flow direction in turn 2000 millimeters open an access hole φ 8-10 millimeter, suspension air pipe (3) is fixedly welded on the delivery duct (1), the more piece pipeline is formed weld, can be in delivery duct (1) outside with being welded No. 9 communicating pipes (9).Shown in figure (1).
