Abstract
The invention relates to the technical field of feeders, in particular to a double screw feeder. According to the double screw feeder, the feeding effect can be effectively guaranteed; the double screw feeder comprises a base, wherein a feeder casing is arranged on the base; a feeding opening is formed in the front end of the feeder casing; a discharging opening is formed in the rear end of the feeder casing; and two spiral blade shafts are arranged in the feeder casing side by side. The double screw feeder is characterized in that the front ends of the spiral blade shafts penetrate through the feeder casing and are connected with and arranged to first bearing blocks of the base; second bearing blocks matched with the spiral blade shafts are arranged on the feeder casing; a speed reducer is connected with the end part of the front end of each spiral blade shaft; the upper end of each speed reducer is connected with a synchronous motor; a triangular convex block is arranged between the two spiral blade shafts in the feeder casing; the top of the triangular convex block is higher than the bottoms of the spiral blade shafts; each spiral blade shaft comprises gradient thread sections and uniform thread sections; the gradient thread sections are correspondingly arranged at the feeding opening; the uniform thread sections are arranged between the feeding opening and the discharging opening; and the thread pitch between the gradient thread sections in the feeding direction is gradually increased.
Description
Technical field
The present invention relates to batcher technical field, specially a kind of double-spiral feeder.
Background technology
The fuel of biomass fuel boiler, needs to use screw(-type) feeder with straw as main fuel in feeding process
It is fed, in order to accelerate feeding efficiency, existing some enterprises employ double-helical batcher, by two helical blades
Axle drives belt so as to realize the rotation of helical-blade bobbin by motor realizing feeding, easily occurs skidding, and drives unstable
It is fixed, and adopt 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 invention provides a kind of double-spiral feeder, which can effectively ensure that feeding effect.
Its technical scheme is such：A kind of double-spiral feeder, which includes base, is provided with batcher on the base
Housing, the batcher housing forward end are provided with charging aperture, rear end and are provided with discharging opening, are 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 run 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 connect reductor, and the reductor upper end connects synchronous motor, in two spirals
In the middle of sharf, triangle convex in the batcher housing, is provided with, is higher than the helical-blade bobbin at the top of the triangle convex
Bottom, the helical-blade bobbin include gradual change thread segment and uniform screw thread section, the gradual change thread segment be correspondingly arranged in it is described enter
At material mouth, it is uniform screw thread section between the charging aperture and the discharging opening, the flight pitch of the gradual change thread segment is along feed
Direction becomes larger.
Which is further characterized by, and the gradual change thread segment is at least including three circle gradual change screw threads；
Maintenance door is provided with the batcher housing at the charging aperture, on the batcher housing of the discharge outlet
It is provided with inspection door.
Using the present invention structure after, helical-blade bobbin directly by reductor and synchronous motor come realize drive, save
The part of the intermediate transfer power such as belt and belt wheel, substantially increases the reliability of driving, and synchronous motor is realized
The synchronous driving of two helical-blade bobbins, triangle convex realize that two screw thread sharfs convey the convenient reliability of material, charging
Material can be compacted by gradual change thread segment at mouthful well, then realize uniform feeding by uniform screw thread section, it is ensured that
Feeding effect.
