Description
Technical field
The utility model is related to Powder Processing Technology in China field more particularly to a kind of anti-uniform feeding devices of bridge formation powder.
Background technology
Since powder particle particle is small, in irregular shape, heap density and strict density diversity ratio are larger, in powder particle
Friction coefficient is larger, and arch formation easily occurs in powder material charging process, i.e. powder easily lumps or even block feed inlet and outlet.
It solves the method that feed powder is built bridge and usually adds vibrator in feed bin lower part, vibrator impacts feed bin so that powder
Material is flowed out from material mouth, however, vibrator is to mobility, general material is effective, and the micro mist poor to mobility does not have effect, this
It is since powder body material granularity is smaller, mobility is poorer, forms column cavity during blanking in feed bin, even if increasing vibrator,
Material bottom can not flowed a little by jolt ramming, material, into feed bin solid accumulation during charging is caused not add how many material relatively, be fed
Effect is also unequal to ideal.
Utility model content
The purpose of this utility model is that solving the problems of the prior art, a kind of anti-bridge formation powder is provided and is uniformly fed dress
It puts, prevents powder material charging process from building bridge.
The technical solution adopted in the utility model is：
A kind of anti-uniform feeding device of bridge formation powder, including funnelform feeding chamber, charge door is located at feeding chamber closing top
The left side in portion, discharge port are located at feeding chamber bottom, it is characterised in that：Vertically center position is equipped with rotation in the feeding chamber
Turn feeding mechanism, rotary feeding mechanism upper end is connect with the motor outside feeding chamber top, and lower end extends to discharging
In mouthful；The rotary feeding mechanism includes circular top plate and circular bottom plate, and even number is equipped between the top plate and bottom plate
Root stirring rod, the stirring rod circumferentially uniformly arrange by mode, upper and lower ends respectively at top plate lower surface edge and bottom plate
Upper surface vertical connection, in the top plate lower surface, center position is vertically equipped with a connecting rod and connecting rod lower end extends
Above to charge door, several braces are additionally provided between the connecting rod lower end and plate upper surface.
Further, middle part is horizontal between the top plate and bottom plate is equipped with circular support plate, and the stirring rod is worn
Support plate and connection fixed thereto are crossed, auxiliary improves the structural stability of rotation feeding mechanism.
Further, be separately installed with a curved bar in two opposite stirring rod, the both ends of curved bar respectively with stirring
Stick epimere side wall and bottom side of the wall connection, assist disturbing powder in feeding chamber, can be gradually to discharge outlet
Transfer.
Further the curved bar bending shape is similar to feeding chamber interior shape, bending part close to feeding chamber side wall and
Bottom wall is disturbed to being gathered in the powder at feeding chamber side wall and bottom in rotary course.
The beneficial effects of the utility model are：
The utility model is susceptible to arch formation to solve during existing powder feed, and vibrator is not suitable for
The problem of poor fluidity powder feeds, devises a kind of anti-uniform feeding device of bridge formation powder, increases inside original feeding chamber
Add and rotary feeding mechanism is formed by top plate, bottom plate, stirring rod and brace etc..Rotary feeding mechanism is integrally in cage structure, rotation
It is small to turn resistance, does not on the one hand interfere with powder feed amount, on the other hand to form a cylindricality stirring region since stirring rod rotates
And cylindricality stirring region is extended in discharge port so that the powder moment by stirring interference effect, prevents it from mutually accumulating mutually
Bridge is overlapped to form, furthermore in the more serious spout area that arch formation occurs, powder is easily assembled inside discharge port
Bridge is overlapped to form, is then rotated by brace and forms a taper stirring region and overlapped with cylindricality stirring region, Stirring causes
For powder by that cannot assemble stop during discharge port, it is broken due to taper stirring region and with cylindricality stirring area that moment forms powder bridge
It badly caves in, powder is even added in equipment.The utility model is simple in structure, suitable for the dosing operation of various powders, energy
Effectively avoid arch formation.
