Description
Technical field
Powder metering field is the utility model is related to, specifically a kind of powder metering conveying device.
Background technology
Powder metering conveying device be it is a kind of fine powder material is stored, conveyed, the device of accurate measurement, be mostly used for city
In city's infrastructure mix mixing equipment, current powder metering conveying device generally has following drawback：It is right when equipment is run
Filler bin carries out powder supply, and powder overflow phenomena now occurs, so as to cause powder metering inaccurate；When equipment is run,
Because of equipment principle problem, powder metering is the fuzzy metering used in certain time period（I.e. non-momentary actual metered）, now
As powder carry is unstable, powder metering can be caused inaccurate；The equipment directly measured after filler bin, easily because filler bin knot
Arch causes stream unstable, so as to cause powder metering inaccurate.
The content of the invention
To solve above-mentioned technical problem, the utility model provides a kind of powder metering conveying device, powder warp
Smoothly transport is crossed, realizes accurately metering, it is simple in construction, it is easy for installation.
To reach above-mentioned purpose, technical scheme is used by the utility model：
A kind of powder metering conveying device, include filler bin, current stabilization storehouse, frequency conversion pressure feeding spiral and metering screw, it is described
Current stabilization storehouse is arranged at the lower section of filler bin and connected by valve, and the current stabilization storehouse, frequency conversion pressure feeding spiral and metering screw are sequentially
Connection, during work, the powder in the filler bin is kept under the control of valve even into current stabilization storehouse, then is entered through current stabilization storehouse
Enter frequency conversion pressure feeding spiral to be steadily fed, reach metering screw and accurately measured.
The valve uses Pneumatic butterfly valve.
The utility model is simple in construction, convenient for installation and maintenance, and follow-up in filler bin adds a current stabilization storehouse, realizes
One after powder falls is buffered, and conveyor screw is fed by frequency conversion again after being kept in current stabilization storehouse, smoothly that powder is defeated
Metering screw is delivered to, metering screw is using bikini pressure sensor collection weight data, by influence of the external environment to metering
It is preferably minimized, ensure that the accuracy of metering.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings：
As shown in figure 1, the powder metering conveying device, includes filler bin 1, current stabilization storehouse 3, frequency conversion pressure feeding spiral 4 and meter
Spiral 5 is measured, the current stabilization storehouse 3 is arranged at the lower section of filler bin 1 and connected by valve 2, the current stabilization storehouse 3, frequency conversion feed spiral shell
Rotation 4 and metering screw 5 are sequentially connected with, and during work, the powder in the filler bin 1 is under the control of valve 2 even into current stabilization
Kept in storehouse 3, then enter frequency conversion pressure feeding spiral 4 through current stabilization storehouse 3 and be steadily fed, reached metering screw 5 and accurately measured.
As preferable mode, the valve 2 uses Pneumatic butterfly valve, small volume and less weight, easily dismounting and maintenance, and can be
Install optional position；Simple in construction tightly to walk, operation moment of torsion is small, and 90 ° of revolution opening speeds, discharge characteristic becomes straight line, regulation performance
It is good.
In the present embodiment, current stabilization storehouse 3 is placed in the lower section of filler bin 1, whether fallen by valve 2 realizing powder and
The flow of powder, batch (-type) feed supplement is carried out to current stabilization storehouse 3, and such powder is kept in current stabilization storehouse 3, alleviated in current stabilization storehouse 3
Storehouse is pressed, and because the volume in current stabilization storehouse 3 is smaller, wherein powder is in fluffy, uniform state, so as to realize powder in next step
Uniform conveying.The powder in current stabilization storehouse 3 is delivered in metering screw 5 by frequency conversion pressure feeding spiral 4, passes through frequency conversion pressure feeding spiral 4
Electrodeless frequency control realize the stable and uniform conveying of powder, and the transporting velocity of powder can be controlled in real time, and and be metering
Accuracy lay the foundation.Metering screw 5 is used as measuring equipment, and weight data is gathered using bikini pressure sensor, will
Influence of the external environment to metering is preferably minimized, and so as to ensure that the accuracy of metering, realizes stable conveying and the essence of powder
Really metering.The component after dynamic measuring is carried out by metering screw 5 to be delivered to again using in equipment, such as mixer etc..
Certainly, it is to be also not limited to the example above to limitation of the present utility model, the utility model that described above, which is not,
The variations, modifications, additions or substitutions that those skilled in the art are made in essential scope of the present utility model, also should
Belong to the scope of protection of the utility model.
