It is regular polygon or rectangular parallelepiped structure to state material and disperse device, close to one side of funnel bottom end opening perpendicular to screw rod.It is specific
It act as coming the material dispersion to lump by the pressure between screw rod and screw sleeve, restores original pulverulence.
The funnel is the device for holding material, ensures that material supply is abundant；Its taper is not less than 45 °, and bottom end opening
Size matches with screw sleeve, ensures that screw sleeve can be fixed at bottom end opening, and the two does not produce relative sliding, center is one
On straight line.
The holder is to ensure electric machine main shaft, screw rod, screw sleeve, funnel bottom outlet as support for whole device
Center on the same line, provide necessary condition for the normal operation of equipment.
A method of it is fed intake, is included the following steps using vertical micro charging device：
Step 1）The vertical micro charging device is installed on the pipeline of cleaner air flow inlet, granular material is put into
In funnel;
Step 2）Start stepper motor switch button, drives screw rod rotation, material is taken out of funnel under the driving effect of screw rod；
Step 3) material falls, and into the pipeline of air flow inlet, under the action of material disperses device, makes due to screw rod and spiral shell
The material that pressure effect between rod set flocks together disperses, its is made to feed intake evenly dispersedly；
Step 4）Screw rod velocity of rotation is changed by regulation motor rotating speed using the frequency converter of stepper motor, controls object
The injected volume of material realizes the micro uniform dispensing of material.
The beneficial effects of the invention are as follows：The vertical micro charging device of one kind and method, wherein speed change gear adjust stepping electricity
Machine rotating speed drives screw rod to provide stable driving force；Screw rod disperses device and is used cooperatively with screw sleeve, material, make material dispersion,
Uniformly, continuous supply；Funnel ensures that material supplies surplus, and material supply is made not to be interrupted；Holder ensure screw rod and screw sleeve,
Hopper outlet is to the heart, on same straight line.The vertical micro charging device can realize within the scope of 0.1-5g/min uniformly, point
It dissipates, be fed to steady and continuous.Finally realization disperses, is uniform, stablizes, being continuously fed, to meet industrial or laboratory applications mistake
Requirement in journey.
