Specific embodiment]
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Usually here in attached drawing description and
The component of the utility model embodiment shown can be arranged and be designed with a variety of different configurations.
In addition, being only used for distinguishing description if there is term " first ", " second ", " third " etc., and should not be understood as indicating
Or imply relative importance.
As shown in Figure 1-3, structure such as Fig. 1 of the utility model embodiment solid material metering device, including：Feed portion
Divide, metering section；
Feed section, the top in metering section, including feed bin 1, the first belt conveyor 2, motor 3.First belt
Motor 3 is housed, raw material is sent out from 2 end of the first belt conveyor on conveyer 2；
Metering section is in feed section in the following, including scale hooper 4, the second belt conveyor 7, scale hooper 4 and the second skin
Band conveyer 7 is connected, and forms Weighing body；Scale hooper 4 is connect by connector 8 of weighing with Weighing body 6, on belt conveyor
Equipped with decelerating motor 9, the operating of 9 driving conveying belt of decelerating motor, Weighing body centre is equipped with 5 weighing body of weighing sensor and weighs,
Weight body 6 is connected below weighing sensor 5, weight body 6 is in metering section lower part.The quantity of weighing sensor 5 is three.
Wherein belt conveyor could alternatively be auger.
As shown in figure 3, metering device further includes PLC controller and touch screen and frequency converter, PLC controller connection weighing is passed
The motor 3 and frequency converter of sensor 5, feed section, frequency converter are connect with metering section decelerating motor 9.
The following are one of setting of the High Accuracy Solid material measuring device of the utility model citings, and this is practical new
Type not only only has this working method, and the parameter of setting is also and not exclusive.
The course of work is as follows：After metering device starting, PLC detects Weighing body weight first, lower than setting maximum upper limit weight
When amount, start and be fed the first belt conveyor 2, in feedstock transportation to metering section scale hooper 4, until reaching preset Weighing body
When maximum upper limit weight, stop the first belt conveyor 2 feed.The weight value of PLC record this moment, PLC are pre- by Setting signal *
If maximum range, calculate an output revolving speed, export to frequency converter, the second belt conveyor of Frequency Converter Control metering section 7
Outputting material is operated, PLC starts integrating velocity amplitude, and PLC records weight value this moment again after 30 seconds.According to formula：Per small
When instantaneous flow=（Weight after weight -30 seconds before 30 seconds）Speed integrating value * 120 in/30 seconds.It is calculated automatically according to this value PLC
Maximum range under current material jaw opening.This calculates range * Setting signal in next step, and PLC is exported at once to frequency converter, frequency converter control
7 revolving speed of the second belt conveyor of metering section processed exports accurate flow.Next 30 seconds repetition this step.Such maximum range
New range can be constantly calculated, has been built such that in 30 second period, the second belt conveyor revolving speed and raw material are made every 30 seconds
The corresponding relationship of instantaneous flow.Second belt conveyor revolving speed has the condition for following input signal to change immediately.Due to not
It is adjusted as the PID generallyd use again, so tracking velocity is completed in several seconds, has accomplished quick adjusting, this is this metering dress
Set a big advantage.Until when raw material weight is reduced to setting limit weight in weighing hopper 4, the automatic range that calculates stops this process
Only, the second belt conveyor of metering section 7 continues the speed operation calculated by current range, the first belt conveyor of feed section
2 startings stop charging after quickly raw material being added to again the setting upper limit weight of scale hooper 4.Again primary every 30 seconds, automatically
Range is calculated, this completes a cyclic processes.By the above course of work it is found that thering is interval weighing difference to calculate range, than logical
Calculate instantaneous flow with instant weighing, for DYNAMIC SOLID weighing, measuring accuracy can be much higher, and measuring accuracy not by
Zero point of weighing influences, this is also another big advantage of this metering device.In addition, 4 material jaw opening of feed bin 1 and scale hooper, depending on institute
Requirement journey, suitably manually adjusts.
The present apparatus is also added into perfect warning note, is detected and controlled by PLC controller, there is belt conveyor
（Or flood dragon）Fracture alarm, belt conveyor stall alarm etc..
Above description is merely a prefered embodiment of the utility model, on the protection scope of the utility model is not limited in
Embodiment is stated, for a person skilled in the art, what is carried out without departing from the principles of the present invention several changes
Into these improvement also should be regarded as the protection scope of the utility model.
