Description
Technical field
The invention belongs to Geldart-D particle fields, are related to a kind of straight suction nozzle of the novel bitubular.
Background technology
Geldart-D particle refers to the energy using air-flow, is stream along airflow direction conveying granular material in closed conduit
A kind of concrete application of state technology.The structure of Pneumatic conveyer is simple, easy to operate, can make horizontal, vertical or incline
The conveying of tilted direction, can be also carried out at the same time in transmission process material heat, cool down, drying and the physical operations such as air current classifying
Or certain chemical operations.
Geldart-D particle is broadly divided into suction and conveying formula and pressure sending type two types according to operation principle.When gas in conveyance conduit
When pressure subatmospheric power, referred to as suction and conveying formula Geldart-D particle, after wind turbine starts, when reaching certain vacuum degree in pipeline,
Air in air is portable to enter pipeline with material by suction nozzle, and the separator of delivery end is transported to along pipeline.It is detaching
In device, material and air separation, the material isolated draws off by separator bottom, and air by after deduster dedusting through wind turbine
It is discharged into air.
When using the Geldart-D particle of suction and conveying formula, suction nozzle is a very important component, the quality of the component capabilities, directly
Connecing influences continuous, efficient, the stable operating of transport system, so will be according to material characteristic and transport condition etc. when design
Factor reasonable selection.
At present when carrying out suction and conveying formula Geldart-D particle, most common suction nozzle is double telescopic straight suction nozzles, its primary structure
It is made of inner and outer tubes, outer tube can be realized by adjusting bolt and be moved up and down, to adjust the end clearance between inner and outer pipes.
When work, material and partial air are entered by the trumpet type port of inner tube, and supplement air, that is, auxiliary air is through between inner and outer pipes
Annular space from top to bottom enters inner tube.Outer tube is adjusted by adjusting bolt to move up and down to change between inner and outer pipes lower end surface
Gap makes material effectively be accelerated to adjust the auxiliary air amount for entering inner tube from annular space.
But adjust four adjusting bolts manually and be difficult to ensure that outer tube uniform force, displacement are identical, influence inside and outside end surfaces
Gap causes to feed unstable；Suction nozzle is connect with suction tube using plain bolt simultaneously, keeps dismounting inconvenient；And outer tunnel end
Portion's circular arc, increases manufacture difficulty；Conventional suction nozzle inner and outer pipes are determined with one heart and are play the guiding role by sliding block, and auxiliary air is by inside and outside
Enter between pipe and generate friction with sliding block, not only increase pressure loss but also influence the efficiency of conveying air, inner and outer pipes can be mutually
It is mobile, under the force effect that rubs, vibrations are easy tod produce, cause suction unstable.
In order to solve problem above, the present invention devises a kind of straight suction nozzle of the novel bitubular.
Invention content
The purpose of the present invention is：A kind of straight suction nozzle of the novel bitubular is devised, it has simple in structure, easy to process, side
Just the characteristics of adjusting material capture velocity, while the flowing of material can be accelerated when absorbing material, improve the suction of material
Take efficiency.
The technical scheme is that：
A kind of straight suction nozzle of the novel bitubular, primary structure are made of inner and outer tubes, and bottom of inner tube is set as horn mouth, and
The indentation with certain altitude, inner tube are processed on bell-mouthed bottom edge（1）And outer tube（2）It is fixed by welding in one
It rises, and the bottom of outer tube and the horn mouth bottom of inner tube are fixed by welding together at the bottom interface to ensure outer tube,
Two secondary air inlets have been symmetrical arranged in outer tube upper-end part of driving, and have been mounted with two valves at secondary air inlet（3）, pass through
Control valve（3）Openings of sizes control the auxiliary air amount of entrance, reach and accelerate material particles movement and adjust inner tube（1）
The effect of conveying air velocity.
In a kind of straight suction nozzle of the novel bitubular, outer tube（2）And inner tube（1）Entirety is fixed and welded together, and is formed
The vessel of certain volume, and inner tube（1）Bottom is designed as horn mouth, and is processed with certain high on bell-mouthed bottom edge
The indentation of degree, the flowing and auxiliary air for facilitating material enter inner tube（1）.
A kind of straight suction nozzle of the novel bitubular, it is characterised in that：Auxiliary air inlet is by valve（3）To control
, two valves on outer tube are mounted on by adjusting（3）Openings of sizes, to control the inlet of auxiliary air；Pass through rotation
Rotary valve door（3）Valve handle（5）, make valve butterfly（6）With valve fixed baffle（7）Between partly overlap, shape
At certain gap, to adjust the auxiliary air amount size of entrance.
A kind of straight suction nozzle of the novel bitubular, which is characterized in that the connection of the horn mouth and outer tube of bottom of inner tube is such as
Shown in Fig. 3, the wedge angle at horn mouth position（9）Weld together with outer tube.
Suction nozzle is inserted into material heap appropriate depth by a kind of straight suction nozzle of the novel bitubular at work, at this time suction nozzle
Inner tube is by with certain vacuum degree, and air at this time enters suction nozzle inner tube through two approach, and a part is by the bed of material and takes
Band material particles enter inner tube by suction inlet, another part via valve openings at, then entered by the sawtooth notch of bottom of inner tube
Inner tube, this partial air, that is, auxiliary air help to be transported material Particle Acceleration and adjust the conveying air velocity of inner tube.Drawing object
When material, we can control valve openings of sizes at any time, to realize absorbing material particle rapidly and efficiently.
Compared with the straight suction nozzle of the existing frequently-used bitubular, it is an advantage of the invention that：One, simple in structure, it is easy to process, due to interior
Pipe and outer tube are directly to be welded and fixed together, and do not have to processing outer tube circular arc portion, greatly reduce the difficulty of processing of suction nozzle；
Two, suction nozzle auxiliary air amount of the invention, it is only i.e. adjustable by the openings of sizes of valve, it is no longer necessary to by adjusting bolt come
Reach the section gap adjusted between inner and outer tubes, greatly reduces adjusting difficulty；Three, suction nozzle inner tube bottom end is designed as sawing
Odontoid facilitates the flowing of material and auxiliary air, plays the role of that material is accelerated to draw.
