Parameter compare.6, the parameter of spiral weighing balance is revised on the basis of measured value after comparing.This scheme is maximum
Disadvantage be exactly when demarcating complete equipment necessarily be in shutdown status, and calibration needs to expend long time.
Utility model content
The utility model provides a kind of caliberating device of continuous asphalt mixing plant powder metering helix balance,
Complete equipment necessarily is in shutdown status when main purpose is to overcome existing powder to demarcate, and demarcates when needing to expend very long
Between the shortcomings of.
The utility model adopts the following technical solution：
The caliberating device of continuous asphalt mixing plant powder metering helix balance, including middle transition metering
Bucket, the powder inlet on middle transition weighing hopper top is connect by Pneumatic butterfly valve with the meal outlet of powder holding vessel, in described
Between the bottom of transition weighing hopper go out powder screw conveyor equipped with one, it is described go out powder screw conveyor be obliquely installed, and under its inclination
End is docked with the bottom of the middle transition weighing hopper, this go out powder screw conveyor slanted upper end and powder metering helix balance into
Material mouth is docked, and the discharge port of the powder metering helix balance is connected to continous way mixture a mixing bowl.
Further, the discharge port of the powder holding vessel connects a rotary plow feeder, which passes through method
It is blue to be fixedly connected with the Pneumatic butterfly valve.
Further, the middle transition weighing hopper includes batch box and weighing sensor, and the batch box passes through suspension
Below the weighing sensor.
Further, the powder metering helix balance is made of screw conveyor and weighing sensor, the helical feed
Machine floats be set on the weighing sensor completely.
Further, the screw conveyor uses three-point support structure, one of supporting point to be equipped with described weigh
Sensor, other two supporting point are equipped with hinges.
Further, the caliberating device of the utility model powder metering helix balance further includes a computer control, institute
State computer control respectively with the Pneumatic butterfly valve, middle transition weighing hopper, go out powder screw conveyor and powder metering spiral shell
Revolve scale connection.
By the above-mentioned description to the utility model structure it is found that compared to the prior art, the utility model has following excellent
Point：
1, the utility model is additionally arranged middle transition weighing hopper, and middle transition weighing hopper powder inlet passes through Pneumatic butterfly valve and powder
Expect holding vessel connection, when calibration, Pneumatic butterfly valve is closed, with the operation for going out powder screw conveyor of middle transition weighing hopper, in
Between powder weight in transition weighing hopper gradually reduce, gradually decreased by detecting the powder weight in middle transition weighing hopper
Velocity arithmetic goes out the actual measurement yield that middle transition weighing hopper bottom goes out powder screw conveyor, by this actual measurement yield and powder metering spiral shell
The yield parameters of rotation scale are compared.If there is inconsistent after comparison, then the amendment ginseng of modification powder metering helix balance automatically
Number, keeps it consistent with measured value.The utility model realizes on-line proving of the mixing plant under not shutdown status.
2, powder metering helix balance is by weighing sensor and the helical feed unit being set on weighing sensor that floats completely
At since screw conveyor rotating speed is constant, and the weighing sensor weight signal for being placed in its bottom can reflect powder
Uninterrupted, be equivalent to a flowmeter.
3, screw conveyor uses three-point support structure, one of supporting point to be equipped with the weighing sensor, in addition
Two supporting points are freely movably hinged.When powder weight changes and leads to the support of screw conveyor pair three in screw conveyor
When point pressure changes, then the weighing process that powder screw claims is realized.
