[background technology]
Airflow milling is to inject disintegrating area after compressed air is accelerated into supersonic airstream through special nozzle to make material be in fluidised form
Change (flow expansion suspends in fluidized-bed and seethes with excitement and collide with each other), therefore each particle has identical motion state.
Disintegrating area, accelerated particle mutually clashes crushing in each nozzle joint.Material after crushing is raised air-flow and is delivered to point
Level area, the fine powder for reaching granularity requirements is filtered out by horizontally disposed grading wheel, and the not up to meal of granularity requirements is returned and crushed
Continue to crush in area.Qualified fine powder is collected with air-flow into efficient cyclone separator, and dusty gas is through dust-precipitator filtration, purification
After enter air.But when raw material enters and grinds often because the pressure inside grinding chamber causes raw material very slow or seldom enters
The grinding chamber for arriving, and then influence the crudy and yield of product.
[utility model content]
The purpose of this utility model seeks to solve above-mentioned deficiency and provide a kind of air-flow for not influenceing airflow milling to work
Mill continuous feeding device, solve the pressure inside grinding chamber cause raw material very slow or grinding chamber that is seldom entering into and cause
Product processing quality is unstable and production capacity deficiency this technical problem.
A kind of continuous feeding device for jet mill, including charging butterfly valve 1, limit switch 1, electricity are designed to achieve the above object
Magnet valve 1, intermediate buffer tank 4, discharging butterfly valve 5, limit switch 26, magnetic valve 27, equilibrium air pressure butterfly valve 8, magnetic valve 39 and
Limit switch 3 10, the upper end of the intermediate buffer tank 4 is provided with charging butterfly valve 1, and limit switches are installed on the charging butterfly valve 1
One 2 and magnetic valve 1, the lower end of the intermediate buffer tank 4 is provided with discharging butterfly valve 5, installs limited location on the discharging butterfly valve 5 and opens
26 and magnetic valve 27 are closed, equilibrium air pressure butterfly valve 8, the balance are installed on the discharge duct at the middle part of the intermediate buffer tank 4
Magnetic valve 39, limit switch 3 10 are equiped with air pressure butterfly valve 8.
The charging butterfly valve 1, discharging butterfly valve 5, equilibrium air pressure butterfly valve 8 are Puffer-type butterfly valve.
The exhaust end of the equilibrium air pressure butterfly valve 8 is provided with filter 11.
The concentration of emission of the filter 11 is≤20mg/m3。
The charging butterfly valve 1 is arranged on raw material cabin outlet at bottom, and the intermediate buffer tank 4 and discharging butterfly valve 5 are arranged on gas
The charging aperture of stream mill main frame.
The utility model compared with the existing technology, by the alternation of upper and lower two groups of butterfly valves and the butterfly valve of intermediate exhaust,
Avoid the feed pipe feed system that the compressed air of airflow milling cavity passes through causes feed system malleation, and proportion is lighter
Powder cannot be normally entered and is processed in airflow milling grinding chamber；And, the present apparatus be with the addition of at equilibrium air pressure gas permeability compared with
Good filter, emission request≤20mg/m3, so that the residual gas pressure of storage tank can be discharged smoothly in when both ensure that charging
Outward, working environment is also protected, while the groceries that it also avoid the external world pollute raw material；Additionally, the utility model is in electric-controlled
System aspect have also been made corresponding chain control, and every group of opening and closing of butterfly valve has corresponding position display and control, each job step
It is rapid to be driven by corresponding position feed back signal, to ensure the reliability of this feed arrangement.
[brief description of the drawings]
Fig. 1 is structural representation of the present utility model；
In figure：1st, charging butterfly valve 2, limit switch 1, magnetic valve 1, intermediate buffer tank 5, discharging butterfly valve 6, limit
Bit switch 27, magnetic valve 28, equilibrium air pressure butterfly valve 9, magnetic valve 3 10, limit switch 3 11, filter.
[specific embodiment]
