Description
Technical field
The utility model is related to batcher technical field, specially a kind of double-spiral feeder.
Background technology
The fuel of biomass fuel boiler with straw as main fuel, it is necessary to use screw(-type) feeder in feeding process
It is fed, in order to accelerate feeding efficiency, existing some enterprises employ the batcher of double helix, by two helical blades
Axle realizes feeding, and belt is driven so as to realize the rotation of helical-blade bobbin by motor, easily occurs skidding, and drives unstable
It is fixed, and use equidistant screw thread, the Density inhomogeneity of material in feeding process, it is unstable to add driving, have impact on feeding
Effect.
The content of the invention
In order to solve the above problems, the utility model provides a kind of double-spiral feeder, and it can effectively ensure that feeding
Effect.
Its technical scheme is such：A kind of double-spiral feeder, it includes base, batcher is provided with the base
Housing, the batcher housing forward end is provided with charging aperture, rear end and is provided with discharging opening, is arranged side by side in the batcher housing
There are two helical-blade bobbins, it is characterised in that the helical-blade bobbin front end is through the feeder housing and is connected and installed in
First bearing seat on the base, is provided with the second bearing coordinated with the helical-blade bobbin on the feeder housing
Seat, the helical-blade bobbin forward end connects reductor, and the reductor upper end connects synchronous motor, in two spirals
In the middle of sharf, triangle convex is provided with the batcher housing, the triangle convex top is higher than the helical-blade bobbin
Bottom, the helical-blade bobbin includes gradual change thread segment and uniform screw thread section, the gradual change thread segment be correspondingly arranged in it is described enter
It is uniform screw thread section at material mouth, between the charging aperture and the discharging opening, the flight pitch of the gradual change thread segment is along feed
Direction becomes larger.
It is further characterized by, and the gradual change thread segment at least includes three circle gradual change screw threads；
Maintenance door, the feed casing of the discharge outlet are provided with the batcher housing at the charging aperture
Inspection door is provided with body.
After structure of the present utility model, helical-blade bobbin is directly realized driving by reductor and synchronous motor,
The part of the intermediate transfer power such as belt and belt wheel is eliminated, the reliability of driving, and synchronous motor is substantially increased
Two synchronous drivings of helical-blade bobbin are realized, triangle convex realizes that two screw thread sharf conveying materials are more convenient and reliable,
Can be compacted for material well by the gradual change thread segment at charging aperture, then realize uniform feeding by uniform screw thread section, be protected
Feeding effect is demonstrate,proved.
