Utility model works principle:
Pulser sends signal, and dust-laden exhaust gas, under dust absorption fan effect, is received by entering-dust mouth
Collection enter dust deashing region, a part of dust because of effect of inertia collide cabinet wall or other
Falling into ash bucket after object, another part waste gas ramps up arrival filter bag, and dust is delayed at filter bag
Outside, clean gas enters in bag, and through bag mouth, gas zones, air port, emptying bank of tubes
Go out.
Deashing is then sent signal by pulser, makes blowing device timing winding-up.Air reservoir is to spray
Mouth provides source of the gas, and nozzle sprays in filter bag, filter bag therefore flash expansion, in adding of producing
Under the effect of speed and back draught, investing the dust releasing in bag to ash bucket, dust is by unloading ash
Mouth is discharged.The dust stratification on dust cloth bag is removed by air pulse blowback, good dedusting effect,
But also the pulse period can be regulated by pulse signal controller and pulse width changes
The persistent period of blowing operation and interval time, make the filtration condition that the holding of dust cloth bag is good,
Dust catching efficiency is high, consumes energy little, and detergent power is strong, processes gas capacity big, safe and reliable to operation,
Simultaneously because be to use compressed air to carry out reverse gas cleaning, dust cloth bag mechanical is moved, and significantly prolongs
Long life is long, and maintenance load is little, additionally compact overall structure, and intensity is high, and rigidity is strong,
Good airproof performance, operates easy to maintenance, beneficially wide popularization and application, is particularly well-suited to five metals, builds
Material, pottery, electronics, chemical industry, casting, aluminum products, control gold, machining, have coloured gold
The dust purification of each industrial circles such as genus, improve five metals, building materials, pottery, electronics, chemical industry,
Casting, aluminum products, control each industrial circle product qualities such as gold, machining, non-ferrous metal with
And reduce workshop dust pollution.
The pressure of explosion-proof pressure sensing device measured medium is sent to pressure sensing by communicating joint
Device, measuring head is the components and parts that can change capacitance, due to the effect of pressure, measures
The capacitance of head changes along with the change face of pressure.The change electric capacity measuring head output is sent to shake
Swinging the agitator of plate, agitator changes frequency of oscillation according to the capacitance of change, shaking of change
Swing the half-wave voltage signal that frequency signal amplifies, detection output frequency of oscillation is little through integrated computation, this
Signal delivers to intelligent microprocessor again.
Explosion-proof type pressure transducer housing uses isolation Explosion-proof Design, and circuit intrinsic safe explosion-proof designs,
Circuit uses signal isolation to amplify, cut-off frequency disturbance-proof design (capacity of resisting disturbance is strong, anti-lightning strike) mistake
Pressure protection, current-limiting protection, shock resistance, anticorrosion, small and exquisite nimble etc..The 316 full soldering and sealing of rustless steel,
Compact structure, compact, there are good moisture protection and excellent media compatibility.
Explosion-proof pressure sensing device air intake need to be connected and fixed with high temperature trachea.
Explosion-proof pressure sensing device is by (PID of cleaner unit energy-saving controller exploitation finely tunes skill
Centered by art), by the Modbus current industry standard agreement of controller, through RS485 interface with
The startup of converter Interface Controller converter, stopping fast frequency shift, set institute by man-computer interface
Needing air duct pressure, current for feedback channel negative pressure to controller and then is automatically adjusted by pressure transducer
Blower fan revolution is to reach energy-efficient.
In design at each air port design automatic air-valve.When production equipment is under stopped status
Air-valve is automatically switched off；By pressure reduction relation, signaling system gather and transmit to microcomputer system；
Read signal by microcomputer system again and change the running frequency of motor；If production equipment is opened
Opening quantity when being 40%, system automatically generates a Fans operational mode.Thus reach to greatest extent
To the purpose reducing energy consumption minimizing use cost.Whole system operation side under micro computer shows
Just；The method of operation is very clear, and has monitoring in real time.Secure context has forward and reverse setting,
Default-phase protection function, overload protection and warning function.
Such as Fig. 6, energy-saving and frequency-variable principle, for blower fan blast one air quantity under constant rotational speed n1
(H-Q) characteristic, curve (2) is pipe network windage characteristic (full trrottle).Curve (4) is
It is the highest that converting operation characteristic (full trrottle) assumes that blower fan is operated in A point efficiency, now blast
For H2, air quantity is Q1, and shaft power N1 is directly proportional to the product of Q1, H2, usable area in the drawings
AH2OQ1 represents.If manufacturing technique requirent, air quantity needs to reduce to Q2 from Q1, at this moment with regulation
The method of air door is equivalent to increase resistance of pipe system, makes resistance of pipe system characteristic change to curve (3), is
Unite and changed to new operating point B operation by original operating point A.As seen from the figure, blast increases on the contrary
Adding, shaft power is directly proportional to area B H1OQ2.Obviously, shaft power declines little.If used
Speed govornor by frequency modulator mode, rotation speed of fan is dropped to n2 by n1, according to the ratio of fan parameter
Law, draws in rotating speed n2 air quantity (Q-H) characteristic, as shown in curve (4).Visible full
In the case of the same air quantity Q2 of foot, blast H3 is greatly lowered, power N3 along with substantially reducing,
Represent with area CH3OQ2.Power △ N=(the H1-H3) × Q2 saved, uses area B H1H3C
Represent.
Bag filter wind-force is affected when the system is operated because winding-up electromagnetic valve damages, and one two
Individual damage is difficult to investigation and finds, Intelligent reading power taking magnet valve state is damaged by native system when electromagnetic valve
Time show which damages and reports to the police to facilitate maintenance to change at touch screen.
The beneficial effects of the utility model are: this utility model smart structural design, rationally,
Have the advantage that
(1) efficiency of dust collection is high, efficiency of dust collection >=99%；
(2) the recyclable process of dust processed；
(3) the overall dimensions of dedusting according to design air flow, can be set；
(4) automaticity is high.
Embodiment of above is only to be described preferred implementation of the present utility model, and
Non-scope of the present utility model is defined, before without departing from this utility model design spirit
Putting, it is various that the technical solution of the utility model is made by this area ordinary skill technical staff
Deformation and improvement, all should fall in the protection domain that claims of the present utility model determine.
