Description
Technical Field
The utility model relates to an airtight rotary feeder with novel design and convenient maintenance.
Background
At present, the rotary feeder is widely used for dedusting and feeding chemical solid particle materials. The material enters the feeder cavity from the feeding hole by means of gravity, is output from the material outlet below the feeder under the driving of the rotation of the rotor, and enters the next procedure. The feeding amount is always controlled by the volume and the rotating speed of the star-shaped rotor. At present, the rotor blade is mostly of a common plate type structure, and for the rotation effect of the rotor, a certain gap needs to be kept between the rotor blade and the inner wall of the storage bin, so that the air tightness between the rotor blade and the inner wall of the storage bin is reduced. Along with the long-time running of the feeder, the air tightness of the worn rotor blade is more difficult to guarantee, and the air leakage quantity greatly influences the air locking performance of the feeder, so that the normal running of the equipment is influenced.
SUMMERY OF THE UTILITY MODEL
To the technical problem, the utility model provides an airtight type rotary feeder, it has made the modified design to the rotor blade, guarantees the rotor normal rotation, has improved the lock gas performance of feeder simultaneously, and blade leak protection material anti-sticking material is effectual.
In order to achieve the technical purpose, the utility model adopts the following technical scheme:
an airtight rotary feeder, characterized in that: the feed bin including the cylinder type, the top of feed bin is equipped with the feed inlet, the bottom sets up the discharge gate, the feed bin outside sets up rotor drive motor, inside rotor and the rotor blade of setting up of feed bin, rotor blade's one end is installed on the rotor, the other end is equipped with the elastic sealing strip with feed bin inner wall contact, rotor blade's tip sets up the open slot, be equipped with a plurality of mounting holes on the open slot, be equipped with the through-hole that corresponds with the mounting hole position on the elastic sealing strip, install elastic sealing strip in the open slot.
Preferably, the inner wall of the bin is uniformly provided with a plurality of convex strips with arc-shaped sections in the radial direction, and the height of each convex strip is lower than that of one end of each rotor blade connected with the corresponding elastic sealing strip.
Preferably, the elastic sealing strip is made of styrene butadiene rubber.
Due to the adoption of the technical scheme, the utility model discloses following technological effect has: the utility model discloses improved design has been made to the rotor blade, guarantees the rotor normal rotation, has improved the lock gas performance of dispenser simultaneously, and blade leak protection material anti-sticking material is effectual.
