Description
Technical field
The utility model belongs to asphalt production equipment field, and in particular to a kind of asphalt-regenerating system for balancing metering pressure difference
System and metering device.
Background technology
Regeneration asphalt equipment working condition of metering：The push-pull valve for regenerating scale hooper is closed, and the push-pull valve for regenerating transitional storehouse is opened, mistake
Storehouse is crossed toward reclaimed asphalt mixture is unloaded in scale hooper, now because material enters in scale hooper, the air being extruded but can not be from weighing
The enterprising smooth discharge of material mouth and underthrust plate valve of bucket, struggle against interior formation malleation interferometer, similar, when scale hooper discharging, mistake
Storehouse push-pull valve is crossed to be closed, the push-pull valve of scale hooper is opened toward its lower chute discharging, now because of material discharge scale hooper,
The air that need to be sucked but can not be from the enterprising smooth suction of material mouth and underthrust plate valve of scale hooper, and the interior negative pressure that formed that struggles against also disturbs meter
Amount, and reclaimed asphalt mixture could need to enter after regeneration drying drum heating and measure link, the regeneration after high-temperature heating
Asphalt is also easy to produce the flue gas of harmful health such as polycyclic organic matter, colloidal particle, so in above-mentioned working condition of metering, claims
Batch box not directly with atmosphere exchange of air with balance bucket in pressure difference, so using said structure metering can not eliminate because entering
Malleation interferometer caused by material or because of negative pressure interferometer caused by discharging, is further improved.
Utility model content
The purpose of this utility model is the shortcomings that overcoming prior art, there is provided one kind can improve measuring accuracy, will can measure
Flue gas in storehouse repeatedly utilizes, the Weighing system of the bitumen regeneration equipment of environmental protection, and another object is to provide a kind of pitch again
The metering device of raw system.
The utility model adopts the following technical scheme that：
A kind of asphalt-regenerating system for balancing metering pressure difference, including regeneration roller, the mistake of connection regeneration roller discharging opening
Storehouse, the weighing hopper for connecting transition bin discharge port external, the flue of one end connection regeneration roller tail gas delivery outlet, in addition to connection is crossed to count
Negative tube between batch box and flue, flue are provided with air exhauster, and air exhauster can make weighing hopper be internally formed negative pressure.
Further, in addition to primary roller, the other end of flue connect the combustion chamber of primary roller.
Further, the negative tube has mountain peak structure, and mountain peak structure includes ascent stage and the descending branch being sequentially connected,
Ascent stage, lower end connected with weighing hopper.
Further, the ventilation interface for being connected with negative-pressure pipeline, the negative tube are provided with the top of the weighing hopper
It is to be flexible coupling between ventilation interface.
A kind of metering device for asphalt-regenerating system, including weighing hopper, the flue for handling tail gas, in addition to negative pressure
Pipe, negative tube one end connect with weighing hopper, and the other end connects with flue, and flue is provided with air exhauster, and air exhauster can make weighing hopper
It is internally formed negative pressure.
From above-mentioned to description of the present utility model, compared with prior art, the beneficial effects of the utility model are：It is logical
Cross and negative tube is set between weighing hopper and flue, air exhauster is set on flue, can make to be formed in weighing hopper metastable negative
Pressure ring border, improve measuring accuracy；Negative tube has mountain peak structure, and mountain peak structure includes ascent stage and the descending branch being sequentially connected,
It is easy to settling particulate matter, avoids negative tube laying dust from blocking；Flue connects with primary roller, can introduce the flue gas in weighing hopper former
