To eliminate the air quality that preamble handles the raising processing environment of dust emission, also on the feed inlet of feeding-passage
Provided with separation dust device, it includes seal closure 34, the whirlpool that seal closure side is arranged in which, which separates dust device,
Flow fan 33 and the main pipe 36 that the other side is arranged in, vortex air outlet is opposite with the air inlet position of main pipe, is vortexed wind
The input terminal of machine is equipped with driving machine 32.Seal closure is set to the stalk feeding inlet of bulking machine (not shown), and makees at sealing
Reason, can effectively stop dust recycling.It is equipped with strainer 35 between main pipe and seal closure, dominates pipe end and is equipped with filter cloth 39, dominate
Pipe is equipped with secondary conduits 37, is equipped with pressure release component 38 in secondary conduits, main pipe exhaust outlet 40 and secondary conduits exhaust outlet 42 are passed through filter
In liquid container 41.Pressure release component includes overflow valve, pressure switch and pressure sensor.
Stalk section after the processing of seal closure upper opening investment preamble (being primarily referred to as hand hay cutter pressure process from this), seal closure are whole
Body uses up big and down small funnel-shaped structure, and since stalk sheet is as loose and porous structure, relative density is smaller, by seal closure
There are certain difficulty when into bulking machine auger feeding mechanism, string configuration can will be made into seal closure in common practice, from
And the stalk material of bottom can be pushed by the stalk material at top, to guarantee that charging is smooth.But if not using the program
It obtains and seal closure is not made long, be unfavorable for the preparation of complete machine.Compaction apparatus can also be increased, but manufacture and dimension can be obviously increased
Protect cost.And after using funnel structure, the chamfered portion of funnel-shaped structure can form sliding force, oppress bottom downwards by self weight
The vertical side of material, funnel structure can then increase the consolidation effect.On the one hand, seal closure length can be shortened, on the other hand,
System for compacting can be saved, has not only simplified overall structure, and reduce operating cost.
Vortex fan generates cyclone under the drive of driving source, since dust monomer weight is light, is easier in vortex
Effect is with eddy motion, to make tiny dust from the biggish stalk section sur-face peeling of volume weight, and is vortexed and then can guarantee
The direction of dust flowing, avoiding dust is in unordered state of disturbance " disorderly flying " in seal closure, but straight along vortex direction diameter
In primary conduit.And strainer has the function of that certain pore size can play limitation and flow into agent particle size, avoid the biggish stalk of volume
Section enters wherein and by line clogging.Stalk section drops downward into bulking machine along seal closure under the action of self-weight, carries out next
Process.After dust leads to strainer, lead to filtrate container along main pipe, absorbed first by filter cloth, completes primary filtering；More tiny
Dust particles pass through filter cloth and then pass through exhaust outlet 40 and be passed through in filtrate to be absorbed by filtrate, completes secondary filter.Further, filter cloth
The purpose for breaing up bubble in filtrate is also acted as, air pocket was avoided and is mingled with dust and be passed through in atmosphere.Finally, by secondary mistake
The clean gas of filter is discharged into atmosphere.
Filter cloth is porous structure, and with the progress of production, the dust on filter cloth is constantly accumulated, if replaced not in time, meeting
Main pipe exhaust outlet 40 is at a time caused to block.At this point, to avoid pipe-line system from blocking, and realize off-load, then leading
Secondary conduits 37 are set by pipe, even if main pipe 36 blocks, eddy airstream can also be flowed along secondary conduits 37, and eventually by
Exhaust outlet 42 is passed through in filtrate.
On the one hand, secondary conduits 37 can be used and the identical structure of main pipe.On the other hand, it can also be set in secondary conduits
The pressure release component being mainly made of overflow valve, pressure switch and pressure sensor is set, while being arranged in driving machine and being used for
The driving circuit for controlling output power of motor, establishes negative feedback loop between pressure release component and driving circuit.Specifically, letting out
The air pressure in the pressure sensor real-time monitoring main pipe of assembly end is pressed, using air pressure as the letter of driving circuit control output power
Number source, when air pressure rises, driving machine output power is reduced, and revolving speed is slack-off；When air pressure is a standard atmospheric pressure, driving machine amount of exports
Determine power.On the one hand the resistance of several parallel connections by relay control can be used, when air pressure is in the control mode of the variable power
When one standard atmospheric pressure, parallel resistance is all accessed.On the other hand the adjustable resistance being made of slide switch then can be used, works as gas
When pressure is a standard atmospheric pressure, adjustable resistance accesses circuit with minimum resistance value.
Meanwhile the overflow valve of controllable exhaust open size is set in secondary conduits end, when air pressure is a normal atmosphere
When 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 discharge, to guarantee to maintain a standard atmospheric pressure in main pipe, and when overflow valve is in fully open state, in main pipe
Air pressure be still higher than a standard atmospheric pressure and (to reach the purpose, the internal diameter of secondary conduits be set as to be less than leading bore, thus may be used
Guarantee that air pressure when using secondary conduits completely in the identical situation of vortex fan discharge quantity of fan is greater than completely using main pipe
Air pressure), then the pressure of main pipe is reduced by control driving machine revolving speed at this time.
Further, since filter cloth blocking is the process gradually changed, 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 by testing in advance, such as:
1) exhaust outlet of leading pipe end is completely closed, when secondary conduits exhaust outlet is fully opened, driving machine is set
For minimum speed r1, corresponding main pipe chocking-up degree is 0.5a+0.5b at this time, a=1, and b=1 is that is, completely plugged；
2) exhaust outlet of leading pipe end is completely closed, when secondary conduits exhaust outlet is fully opened, driving machine is set
For rated speed r2, corresponding main pipe chocking-up degree is 0.5a+0.5b, a=0 at this time, and b=1, i.e. Partial Blocking only remain and starts
Machine revolving speed is controllable；
3) exhaust outlet of leading pipe end is completely closed, when secondary conduits exhaust outlet is completely closed, driving machine is set
For rated speed r2, corresponding main pipe chocking-up degree is 0.5a+0.5b, a=0 at this time, and b=0, i.e. chocking-up degree are 0；
A=1 when revolving speed is minimum speed r1, a=0 when revolving speed is rated speed r2；
B=1 when overflow valve fully opens when secondary conduits end, b=0 when overflow valve completely closes.(or it is set as 0.3a+
0.7b can voluntarily adjust weight shared by motor speed and overflow valve opening degree as needed.)
When chocking-up degree reaches 50b% or more, alarm signal being issued, prompting replacement filter cloth, when to guarantee to replace filter cloth not
Valve is closed when requiring replacement in secondary conduits and main pipe junction setting controllable valve, is made by the progress for influencing production
Air only flows to branch pipe.Filter cloth uses card insert type, replaces convenient and efficient.
