Abstract
The invention provides an improved double-spiral feeder effectively avoiding a bridging blocking phenomenon and ensuring the normal operation of a feeder and a boiler. The improved double-spiral feeder comprises a storage hopper and a spiral conveyer, wherein the upper part of the storage hopper is provided with a feeding hole; the spiral conveyer comprises a driving device, a bearing seat, two spiral blade shafts and a control cabinet; the driving device is in electric control connection with the control cabinet and connected with the bearing seat; and the spiral blade shafts are mounted on the bearing seat and positioned in a shell.
Description
(1) technical field
The present invention relates to biomass fuel boiler apparatus for feeding field, be specially a kind of double-spiral feeder of improvement.
(2) background technology
The fuel of biomass fuel boiler is main fuel with the straw, and batcher in the past mostly is the single-screw feed, because the characteristic of straw itself tends to occur the bridging phenomenon of blocking in course of conveying, hinders the normal operation of batcher.
(3) summary of the invention
At the problems referred to above, the invention provides a kind of double-spiral feeder of improvement, it is not prone to the bridging clogging, can guarantee the normal operation of batcher and boiler.
Its technical scheme is such: it comprises feed bin and helix transporting device, charging aperture is arranged at described feed bin top, described helix transporting device comprises drive unit, bearing block, helical blade axle and switch board, described drive unit and described switch board electricly connect, described drive unit is connected with bearing block, described helical blade axle is installed on the described bearing block, and the helical blade axle is installed in the housing, it is characterized in that: described helical blade axle is provided with two.
It is further characterized in that: described two helical blade axles are parallel to be installed on the described bearing block; Downside is provided with the gusseted plate vertically in the middle of described two helical blade axles; Described drive unit comprises reductor, and described reductor is connected with helical blade axle on being installed in described bearing block by chain; Described housing is an ellipsoidal structure; Described charging aperture is equipped with electronic fireproof door; It also comprises poking device, and described poking device is installed on described feed bin bottom, the helical blade shaft housing; Described poking device comprises motor, turning cylinder, on the described turning cylinder switch-plate is installed, and described turning cylinder is installed on the bulkhead of described feed bin bottom, and the one end is connected with fork, and described fork is connected with described motor by connecting rod; Described poking device turning cylinder rotation angle range is at 120 degree～-120 degree.
Use double-spiral feeder of the present invention, its beneficial effect is: it adopts parallel mounting structure of double helix sharf and poking device, can effectively prevent straw bridging obstruction feed bin, causes the phenomenon of bottom helix transporting device idle running.
(4) description of drawings
Fig. 1 is the main structural representation of looking of the present invention;
Fig. 2 is that the A of Fig. 1 is to cutaway view;
Fig. 3 is the poking device plan structure figure of Fig. 2.
(5) specific embodiment
See Fig. 1, Fig. 2 and Fig. 3, the present invention includes feed bin 1 and helix transporting device, charging aperture 2 is arranged at feed bin 1 top, helix transporting device comprises drive unit, bearing block 4, helical blade axle 3 and switch board, drive unit and switch board electricly connect, and drive unit is connected with bearing block 4, and helical blade axle 3 is installed on the bearing block 4, helical blade axle 3 is installed in the housing 5, and helical blade axle 3 is provided with two; Two helical blade axle 3 parallel being installed on the bearing block 4; Downside is provided with gusseted plate 6 vertically in the middle of two helical blade axles 3; Drive unit comprises reductor 7, and reductor 7 is connected with helical blade axle 3 on being installed in bearing block 4 by chain 8; Housing 5 is an ellipsoidal structure; Charging aperture 2 is equipped with electronic fireproof door 9; Structure of the present invention also comprises poking device, and poking device is installed on feed bin 1 bottom, the helical blade shaft housing 5; Poking device comprises motor 10, turning cylinder 11, and material toggling frame 12 is installed on the turning cylinder 11, and turning cylinder 11 is installed on the feed bin 1 bottom bulkhead, and the one end is connected with fork 13, and fork is connected with motor 10 by connecting rod 14.In the above-mentioned accompanying drawing, switch board does not mark.
The helix transporting device outlet is connected with the boiler feed mouth, the work of switch board control system, reductor 7 rotates, rotate by two helical blade axles, 3 engagements that chain 8 drives on the bearing block 4, material enters feed bin 1 from charging aperture 2, poking device starts, motor 10 drives fork 13 rotations by connecting rod 14, and fork driven rotary axle 11 and material toggling frame 12 are done corresponding rotation, rotation angle range is at 120 degree～-120 degree, make the difficult enough rapid dispersions of the material that enters feed bin 1, be difficult for producing the phenomenon of putting up a bridge and stopping up feed bin and causing the bottom helix transporting device to dally; The gusseted plate of downsides can prevent effectively that material from forming the triangle accumulation area between two helical blade axles in the middle of two helical blade axles, prevents ignite material in the helix transporting device of boiler tempering.
