Specific embodiment
Below in conjunction with Fig. 1 ~ 8, present disclosure is described in detail by specific embodiment.The straw bulking machine separates dust
Device includes seal closure 34, is arranged on the vortex fan 33 of seal closure side and is arranged on the main pipe 36 of opposite side, is vortexed
Air outlet is relative with the air inlet position of main pipe, and the input of vortex fan is provided with driving machine 32.Seal closure is arranged at expanded
Machine（Not shown in figure）Stalk feeding mouth, and make encapsulation process, can effectively stop dust recycling.Between main pipe and seal closure
Filter screen 35 is provided with, leading pipe end is provided with filter cloth 39, and main pipe is provided with secondary conduits 37, and pressure release component 38 is provided with secondary conduits,
Main pipe exhaust outlet 40 and secondary conduits exhaust outlet 42 are passed through in filtrate container 41.Pressure release component includes overflow valve, pressure switch
And pressure sensor.
From the input preamble treatment of seal closure upper opening（This place is primarily referred to as hand hay cutter pressure operation）Stalk section afterwards, seal closure is whole
Body uses up big and down small funnel-shaped structure, and because stalk sheet is as loose and porous structure, relative density is smaller, by seal closure
There is certain difficulty during into bulking machine auger feeding mechanism, common practice can will enter seal closure and be made string configuration, from
And the stalk material of bottom can be pushed by the stalk material at top, so as to ensure that charging is smooth.But if using the program not
Obtain and seal closure is not made thin long, and be unfavorable for the preparation of whole machine.Compaction apparatus can also be increased, but can substantially increase manufacture with dimension
Shield cost.And after using funnel structure, the chamfered portion of funnel-shaped structure can form sliding force, bottom is oppressed downwards by deadweight
Material, the vertical side of funnel structure can then increase the consolidation effect.On the one hand, can be by seal closure contraction in length, another aspect,
System for compacting can be saved, overall structure has not only been simplified, and reduce operating cost.
Vortex fan produces cyclone under the drive of driving source, because dust monomer weight is light, therefore is more easy in vortex
With eddy motion, so that tiny dust is from the larger stalk section sur-face peeling of volume weight, and vortex can then ensure for effect
The direction of dust flowing, it is to avoid dust is in unordered state of disturbance " disorderly flying " in seal closure, but straight along vortex direction footpath
In primary conduit.And filter screen have certain pore size can play a part of limitation flow into agent particle size, it is to avoid the larger stalk of volume
Section enters wherein and by line clogging.Stalk section is dropped downward into bulking machine in the presence of deadweight along seal closure, is carried out next
Operation.After the logical filter screen of dust, filtrate container is being led to along main pipe, absorbed by filter cloth first, completion is once being filtered；More tiny
Dust granules are absorbed in being then passed through filtrate by exhaust outlet 40 through filter cloth by filtrate, complete secondary filter.Further, filter cloth
Also act as the purpose for breaing up bubble in filtrate, it is to avoid cross air pocket and be mingled with dust and be passed through in air.Finally, by secondary mistake
The clean gas of filter are discharged into air.
Filter cloth is loose structure, and with the carrying out of production, the dust on filter cloth is constantly accumulated, if changed not in time, meeting
Main pipe exhaust outlet 40 is at a time caused to block.Now, to avoid pipe-line system from blocking, and off-load is realized, then leading
Pipe side sets secondary conduits 37, even if main pipe 36 is blocked, eddy airstream can also flow along secondary conduits 37, and eventually through
Exhaust outlet 42 is passed through in filtrate.

Press assembly end pressure sensor real-time monitoring main pipe in air pressure, using air pressure as drive circuit controlled output power letter
Number source, when air pressure rises, driving machine power output reduction, rotating speed is slack-off；When air pressure is a standard atmospheric pressure, driving machine amount of exports
Determine power.The control mode of the variable power, on the one hand can be using some resistance in parallel by Control, when air pressure is
During one standard atmospheric pressure, parallel resistance is all accessed.On the other hand then gas can be worked as using the adjustable resistance being made up of slide switch
Press during for a standard atmospheric pressure, adjustable resistance accesses circuit with minimum resistance.
Meanwhile, the overflow valve of controllable exhaust open size is set in secondary conduits end, when air pressure is a normal atmosphere
During pressure, overflow valve is in completely closed state, and when leading overpressure gradually rises, overflow valve is gradually opened off-load, and gas passes through
Secondary conduits are discharged, to ensure to maintain a standard atmospheric pressure in main pipe, and when overflow valve is in fully open state, in main pipe
Air pressure remain above a standard atmospheric pressure（To reach the purpose, the internal diameter of secondary conduits is set to, less than leading bore, thus may be used
Ensure air pressure when in the case of vortex fan discharge quantity of fan identical completely using secondary conduits more than completely using main pipe
Air pressure）, then now by controlling driving machine rotating speed to reduce the pressure of main pipe.
Further, since it is a process for gradually changing that filter cloth is blocked, and it is difficult to observe from outside, therefore in driving machine
Upper setting speed probe, can directly monitor the use state of filter cloth.Can be by testing in advance, such as：
1）The exhaust outlet of leading pipe end is completely closed, when secondary conduits exhaust outlet is fully opened, driving machine is set as most
Small rotating speed r1, now corresponding main pipe chocking-up degree be 0.5a+0.5b, a=1, b=1, i.e., it is completely plugged；
2）The exhaust outlet of leading pipe end is completely closed, when secondary conduits exhaust outlet is fully opened, driving machine is set as volume
Determine rotating speed r2, now corresponding main pipe chocking-up degree is 0.5a+0.5b, a=0, b=1, i.e. Partial Blocking, only remain engine and turn
Fast controllable；
3）The exhaust outlet of leading pipe end is completely closed, when secondary conduits exhaust outlet is completely closed, driving machine is set as volume
Determine rotating speed r2, now corresponding main pipe chocking-up degree is that 0.5a+0.5b, a=0, b=0, i.e. chocking-up degree are 0；
The a=1 when rotating speed is minimum speed r1, the a=0 when rotating speed is rated speed r2；
B=1, the b=0 when overflow valve is completely closed when secondary conduits end overflow valve is fully opened.（Or it is set as 0.3a+0.7b,
Weight that can as needed voluntarily shared by regulation motor rotating speed and overflow valve opening degree.）
