Description
Technical field
The present invention relates to a kind of powder tap density detection means, more particularly, it relates to a kind of determine coke vibration density
The device of degree.
Background technology
The method of measure coke tap density mainly has following two at present：1st, Traditional Method；2nd, instrumental method.The former, is most
Common, the graduated cylinder of also simple selection certain specification is operated, will be treated that test sample loads wherein, and vertically be shaken to volume not with hand
Till change, then tap density is obtained final product with coke quality divided by measurement cylinder reading.But the method is affected greatly, to cause to survey by artificial factor
The precision and poor accuracy of amount result, is not now substantially adopted.
In order to solve human error and loaded down with trivial details workload, tap density is determined at present mostly using tap density meter, rule
Lattice are also more.But these Density Measuring Instruments have the shortcomings that one common, i.e., be all operation in open environment, be not fee from during measure
Particle is affected by air drag, causes institute's measured value react truth, especially powder materials, and the dust for hiking up can also pollute
Environment, has a strong impact on operator's health.
Chinese patent《A kind of measure device of electromagnetism positive pole powder material tap density》（CN202362035）, change
Traditional Density Measuring Instrument, increased a lid on graduated cylinder, prevent powder in continuous mode from sputtering away, to affect measurement result
Accuracy, but do not guarantee whole measurement process in the air-tight state all the time, it is impossible to eliminate the rings such as air drag or humidity
Border factor treats the impact of test sample, ultimately results in measurement result and deviates actual value.
Chinese patent《A kind of new tap density meter》（CN202126381）Devise a kind of more complicated machinery knot
Structure, drives instrument vibration by motor, although can solve the problem that the problem of abundant vibration, but equally cannot be avoided except air drag
Or the environment factor such as humidity treats the impact of test sample.
Content of the invention
The purpose of the present invention aims to provide a kind of device for determining coke tap density, solves to determine Jiao in prior art
Closed problem cannot be truly realized during charcoal tap density.
According to the present invention, there is provided a kind of device of measure coke tap density, including sealing system and vavuum pump.Wherein,

True property.
Description of the drawings
In the present invention, identical reference represents identical feature all the time, wherein：
Fig. 1 is the structural representation of the device that the present invention determines coke tap density.
Specific embodiment
Technical scheme is further illustrated with reference to the accompanying drawings and examples.
In tap density continuous mode, as whole process is in open system, cause powder floats in the environment,
Operator's health is affected, while being affected by environment factors such as air drag and humidity, causes particle packing leakiness, affected
The accuracy of final measurement.The purpose of the present invention exactly in order to solve the above problems, improves working environment, improves measured value
Accuracy.
With reference to Fig. 1, the present invention is mainly made up of 7 big parts：Sealing system 1, Density Measuring Instrument 2, vacuum buffer tank 3, vavuum pump
4th, pressure gauge 5, triple valve 6 and gate valve 7.Below describing effect and the annexation of all parts in detail.
As shown in figure 1, the key of the present invention is sealing system 1, which is by eyepiece 1-1, slit 1-4, gathering hole 1-2 and infrared
Lamp 1-3 is constituted.Density Measuring Instrument 2 is arranged on the bottom of sealing system 1, and graduated cylinder is securable on Density Measuring Instrument 2, and Density Measuring Instrument 2 can vibrate.
The big 2cm of the width ratio graduated cylinder diameter of slit 1-4, length be by Density Measuring Instrument fix at graduated cylinder on the basis of line, until with
Graduated cylinder mouth is concordant, can effectively guarantee volume reading in FOV.
Eyepiece 1-1 is one piece of oval convex lens, can freely slide up and down on slit 1-4, it is ensured that graduated cylinder is carved
Degree line is clear, it is to avoid the error in reading that should be obscured and cause.
Infrared lamp 1-3 guarantees sealing system 1 in dry environment all the time, prevents powder or particle in measurement process
Make moist and stick together so that granularity becomes big, and final measurement deviates actual value, while light makes the ken become brighter clear
Clear.
Gathering hole 1-2 can be closed, is easy to take, varies operation, enables sealing system 1 to guarantee that whole measurement process is in all the time
Under air-tight state, do not affected by environment such as air drag and humidity, it is ensured that measurement result is accurate.
Vacuum buffer tank 3 is set between vavuum pump 4 and sealing system 1, between vavuum pump 4 and vacuum buffer tank 3, passes through lock
Valve 7 connects, and is connected by triple valve 6 between vacuum buffer tank 3 and sealing system 1.Pressure gauge 5, pressure are set on vacuum buffer tank
Power table 5 can be shared with positive/negative-pressure.
The specific operation process that the present invention determines the device of coke tap density is as follows：
Preparatory stage
To treat in test sample charge weight cylinder, then opening operation mouth 1-2 is fixed on graduated cylinder on Density Measuring Instrument 2, shutoff operation mouth
1-2, opens infrared lamp 1-3, opens gate valve 7, and triple valve 6 is pulled to logical main road direction, vavuum pump 4 is finally opened, when vacuum is delayed
When the pressure gauge rushed on tank 3 points to tiny structure, show that air is replaced, close vavuum pump 4, closing gate valve 7.Now, whole
Individual measuring environment in close drying and without any resistance in the state of.
Serviceability limit stage
By in the attaching plug insertion socket of Density Measuring Instrument 1, vibration starts, i.e. measurement starts.When reaching regulation vibration number
Afterwards, power supply is pulled out.Then slip eyepiece 1-1 starts reading to appropriate location, and writes down numerical value.Finally, by triple valve 6 pull to
Atmosphere direction, makes system recover normal pressure, and opening operation mouth 1-2 carries out the measure of next group sample.
Detailed process " prepares " and " serviceability limit stage " step repeatedly.
Can ensure that whole measurement process, in enclosed system, improves operating environment using the present invention, particle is not also received
Truth has been reacted in the impact of the environment factor such as the resistances such as air and humidity, measured result.During reading without the need for by graduated cylinder from close
Remove on degree instrument, it is to avoid should remove graduated cylinder causes sample stacking face artificially to be inclined or overturn and affect final measurement
Accuracy.Meanwhile, two infrared lamps can ensure that system is constantly in dry environment, prevent powder or particle make moist adhesion and most
The accuracy of whole measured value.
Those of ordinary skill in the art is it should be appreciated that above specification is only numerous embodiments of the invention
In one or more embodiments, and not use limitation of the invention.Any equalization for embodiment described above becomes
The technical schemes such as change, modification and equivalent substitute, as long as meeting the spirit of the present invention, will all fall in the power of the present invention
In the range of sharp claim is protected.
