Abstract
The utility model relates to a novel spiral feeding auger. The novel spiral feeding auger comprises an auger shaft, an auger blade and a barrel. One end of the auger shaft is coaxially installed in the barrel, the auger shaft in the barrel is spirally provided with the auger blade, one end of the barrel is communicated with a feeding hopper, the part, located on one side of the feeding hopper, of the barrel is provided with a connecting flange, the part, between the feeding hopper and the connecting flange, of the auger blade is provided with grooves at the interval of half thread pitch, the grooves are perpendicular to the auger shaft, and the parts, corresponding to the grooves, of the barrel are vertically and symmetrically provided with a pair of hinge pins in the radial direction, and the grooves penetrate through the hinge pins when the auger blade rotates. Materials at the compressed section are scattered through the shearing and stirring functions of the hinge pins to the materials at the compressed section, the density of the materials is reduced, the friction force between the materials and the barrel is weakened, and therefore the axial resistance produced in the material pushing process is reduced, the materials can be pushed towards a discharging end conveniently, and meanwhile power consumption of the auger can be reduced.
Description
Technical field
The utility model belongs to drum drying equipment technical field, specifically, is a kind of Novel spiral pan feeding screw feeder.
Background technology
At present, most roller driers are taking spiral pan feeding screw feeder as feeding device.The problem that tradition screw feeder was prone in when work is, while especially carrying wet adhesive material, for example wet sticky amargosite material in the process of feeding, exist pusher difficulty, material wrap up in axle not before, the problem such as pan feeding inefficiency.
The basic reason that causes the problems referred to above is that the design of pan feeding screw feeder inner structure exists defect.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of Novel spiral pan feeding screw feeder is provided, and this screw feeder makes the material loosening of compression section, has reduced the density of material, has greatly improved work efficiency.
Technical solutions of the utility model are achieved in that
A kind of Novel spiral pan feeding screw feeder, comprise screw conveyor shaft, screw feeder blade, cylindrical shell, described screw conveyor shaft one end is coaxially arranged in cylindrical shell, on screw conveyor shaft in this cylindrical shell, spiral is installed screw feeder blade, this cylindrical shell one end connection is installed into hopper, be positioned on the cylindrical shell of this feeder hopper one side butt flange is installed, be shaped with a groove in feeder hopper to every half pitch on the screw feeder blade between butt flange, this groove is vertical with screw conveyor shaft, the upper and lower radial symmetry of cylindrical shell of respective slot is installed a pair of bearing pin, and groove is through bearing pin described in screw feeder blade when rotation.
And, the open gap of described groove is pin diameter 1.25 times.
And the lead angle of described screw feeder blade is 15 degree.
And described bearing pin is coaxially installed captive nut and jam nut, described captive nut is welded on cylindrical shell, adjusts the extension elongation of bearing pin by the spanner adjustable side of end part of pin shaft, by jam nut, lock clasp is fixed.
And described end part of pin shaft to the distance between screw conveyor shaft is 5mm.
Advantage of the present utility model and good effect are:
The conveying of material in screw feeder is divided into three phases: pan feeding section, compression section and extruding zone, bearing pin installation site is mainly distributed in compression section.By bearing pin to material shearing, the beating action in compression section, make the material loosening of compression section, reduce the density of material, weaken the friction force of material and cylindrical shell, thereby reduce the axial resistance producing in material progradation, be convenient to the propelling of material to discharge end, can also reduce the power consumption reduction of screw feeder simultaneously; This screw feeder can also weaken the deboost of screw conveyor shaft, the service life of extension device greatly simultaneously.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model screw feeder blade;
Fig. 3 is the structural representation of the utility model bearing pin.
Detailed description of the invention
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of Novel spiral pan feeding screw feeder, as shown in Figure 1, comprise screw conveyor shaft 1, screw feeder blade 2, cylindrical shell 3, described screw conveyor shaft one end is coaxially arranged in cylindrical shell, on screw conveyor shaft in this cylindrical shell, spiral is installed screw feeder blade, this cylindrical shell one end is communicated with and is installed into hopper 6, is positioned on the cylindrical shell of this feeder hopper one side butt flange 5 is installed.
Innovative point of the present utility model is:
Be shaped with a groove 7 in feeder hopper to every half pitch on the screw feeder blade between butt flange, this groove is vertical with screw conveyor shaft, thereby screw feeder blade is separated into multiple equidistant blades, the upper and lower radial symmetry of cylindrical shell of respective slot is installed a pair of bearing pin 4, and groove is through bearing pin described in screw feeder blade when rotation.
In the present embodiment, the open gap of described groove is pin diameter 1.25 times, object is the insertion of being convenient to bearing pin, the lead angle of described screw feeder blade is 15 °, as for screw feeder blade outside diameter, screw pitch can be according to user's feeding flexible.
The structural representation of described bearing pin as shown in Figure 3, this bearing pin is coaxially installed captive nut 9 and jam nut 8, described captive nut is welded on cylindrical shell, adjust the extension elongation of bearing pin by the spanner adjustable side 10 of end part of pin shaft, by jam nut 8, bearing pin is fixed, thereby be convenient to adjusting pin shaft end with respect to the distance between screw conveyor shaft.
Described end part of pin shaft to the preferred distance between screw conveyor shaft is 5mm.
The beneficial effects of the utility model are:
The conveying of material in screw feeder is divided into three phases: pan feeding section, compression section and extruding zone, bearing pin installation site is mainly distributed in compression section.By bearing pin to material shearing, the beating action in compression section, make the material loosening of compression section, reduce the density of material, weaken the friction force of material and cylindrical shell, thereby reduce the axial resistance producing in material progradation, be convenient to the propelling of material to discharge end, can also reduce the power consumption reduction of screw feeder simultaneously; This screw feeder can also weaken the deboost of screw conveyor shaft, the service life of extension device greatly simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
