Abstract
The invention relates to a double auxiliary pipe pneumatic conveying pipeline, which improves an air supply mode into staged air supply, avoids air waste of series air supply of a single auxiliary pipe, and supplies a small quantity of air through a local material blocked pipe in a main conveying pipe, so as to save the air. Moreover, the double auxiliary pipe pneumatic conveying pipeline can effectively control the air quantity in the main conveying pipe, and is favorable for reducing the conveying air velocity. The double auxiliary pipe pneumatic conveying pipeline comprises the main conveying pipe which is arranged between a middle bin and a target bin, and the auxiliary pipe which is arranged in parallel to the main conveying pipe, wherein a plurality of sections of branched conveying pipes are arranged between the main conveying pipe and the auxiliary pipe, and each section of branched conveying pipe is respectively communicated with the main conveying pipe and the auxiliary pipe.
Description
Technical field
The present invention relates to a kind of two auxilliary pipe delivery duct that strength is carried powder and granule shape material that is used for, belong to mechanical manufacturing field.
Background technology
In the storage and transportation apparatus such as feed bin of existing storage, loading powder and granule shape material, need carry out fluidization to material for the normal conveying that guarantees material and handle.
It is carrier is carried the powder material in closed conduit a kind of mode of movement with the pressure gas exactly that strength is carried, and existing strength is carried the three kinds of modes that generally are divided into, i.e. dilute phase conveying, the close conveying mutually and hybrid conveying.For existing polytype powder and granule shape material, adopt the dilute phase conveying can be easier to form bolt stream, and the shortcoming that dilute phase is carried is that air consumption is big, be difficult to satisfy the material that transportation performance is had relatively high expectations.Adopt close phase mode of movement, its material-gas ratio is big, carry gas speed lower, and material is easy to form bolt stream, sand dune stream or moving bed and flows in pipeline, thereby forms lower floating velocity, be easy to reduce the percentage of damage of material and the wearing and tearing that improve pipeline.
Pneumatic conveying mode comparatively commonly used at present is to adopt the auxiliary tube tonifying Qi to stop up to prevent that effectively pipeline is local.Such as auxiliary tube in the outside increase of main delivery pipe one bypass.When the main feedline part bolt occurs when stifled, in main feedline, carry out tonifying Qi realizing broken arch by auxiliary tube, so can in a pipeline, carry various materials.
The shortcoming that existing hybrid conveying exists is, when in main feedline, carrying out tonifying Qi by auxiliary tube, fed distance is longer, the tandem tonifying Qi of Dan Fuguan needs bigger tolerance, often do not occurring expecting that stifled position also charges into pressure gas, therefore the gas speed in the main feedline is higher, also is unfavorable for reducing the percentage of damage of material.
Summary of the invention
Pneumatic conveying pipeline with two auxiliary pipes of the present invention, its purpose is to address the above problem and adopts two assisting to manage segmentation structures, promptly between main feedline and auxiliary tube, be provided with multistage branch delivery pipe, realize carrying out targetedly tonifying Qi to change according to the local material pressure in the main feedline.
The objective of the invention is to, the tonifying Qi mode is improved to interim tonifying Qi, avoided the tolerance waste of Dan Fuguan tandem tonifying Qi, according to the replenishing of a small amount of gas of the local material plugging carrying out of main feedline in-to-in, to reach the purpose of solar term.
Another purpose is that control enters the tolerance in the main delivery pipe effectively, helps reducing and carries gas speed, helps reducing percentage of damage, the reduction plugging time of run of material.
For achieving the above object, Pneumatic conveying pipeline with two auxiliary pipes of the present invention comprises a main feedline that is arranged between intermediate bunker and the purpose feed bin and an auxiliary tube that be arranged in parallel with main feedline, wherein,
Be provided with multistage branch delivery pipe between main feedline and auxiliary tube, every section branch's delivery pipe is communicated in main feedline and auxiliary tube respectively.
As above-mentioned scheme feature, every section branch's delivery pipe is at the different parts of main feedline, when plugging appears in a certain part, material occurs than great fluctuation process in main feedline internal pressure and flow velocity, in main feedline, mend from auxiliary tube by a certain branch delivery pipe this moment and go into pressure gas, can will should break arch by the part putty.
Further improving design is that described branch delivery pipe is not communicated with each other mutually.Each section branch delivery pipe with the place of connection of auxiliary tube one connection control cock being set, is provided with shutoff valve or plug at branch's delivery pipe end simultaneously.
Increase some branches on auxiliary tube, can change original disposable tandem tonifying Qi mode into stage tonifying Qi in parallel with respect to Dan Fuguan, really having reached which part needs tonifying Qi just to carry out the solar term purpose of tonifying Qi.
In addition, can with the corresponding position of each section branch delivery pipe, a pressure sensor is set on main feedline.Pressure boost sensor on cooresponding main feedline can determine whether the connection control cock on branch's delivery pipe should be opened by the force value of pressure sensor feedback.
The end of described auxiliary tube is communicated in main feedline, can realize carrying out to the end of main feedline by original auxiliary tube the operation of tonifying Qi.
Content to sum up, advantage of the present invention and beneficial effect be, realized a kind of stage tonifying Qi, avoided the tolerance waste of Dan Fuguan tandem tonifying Qi.Also may command enters the tolerance in the main delivery pipe, helps reducing carrying gas speed, helps reducing percentage of damage, the reduction plugging time of run of material.
