Abstract
A variable-diameter single-screw-shaft dehydrating device comprises a frame, a driving device, a feed component, a discharge component, a tapered sieve cage and a driving rotary shaft. The feed component and the discharge component are arranged at two ends of the frame. The tapered sieve cage is arranged in the frame. The driving rotatory shaft is mounted in the sieve cage and is coaxially arranged with the sieve cage. The driving device is connected with one end of the driving rotary shaft. A screw blade is arranged on the driving rotary shaft. The diameter of the screw blade gradually decreases along with the inner diameter of the tapered sieve cage. The diameter of the driving rotary shaft gradually increases along with decrease of the inner diameter of the sieve cage. The screw pitch of the screw blade gradually decreases along with the increase of the diameter of the driving rotary shaft. The variable-diameter single-screw-shaft dehydrating device is good in dehydrating effect and smooth in equipment water discharge, moisture content of dehydrated materials is obviously reduced as compared with the original moisture content, and energy as required by follow-up drying is greatly reduced.
Description
Technical field
The invention belongs to drying device field, be specifically related to a kind of single-screw squeezing machine for material mechanical presses dehydrations such as maize germ, fibers.
Background technology
Single-screw squeezing machine is a kind of mechanical presses dewatering drying device, often be applied to food, grain, feed deep processing industry, the large material of multiple water content is had to good dehydrating effect, for material is finally dried energy saving condition is provided, greatly reduce dry total power consumption.
Existing single-screw squeezing machine is comprised of frame, feeding assembly, discharge component, helical axis, sieve cage and drive unit, sieve cage inwall is provided with one deck screen cloth, helical axis is straight barrel type, two ends diameter is identical, be arranged in the middle of sieve cage, on axle, have some blades, blade diameter changes along with the variation of sieve cage internal diameter.Material enters from charging main part, drive unit drives helical axis rotation, blade rotary pushes material forward impelling, because blade pitch shortens, the space of material in sieve cage also diminishes thereupon, and moisture content is wherein squeezed out gradually, and discharges through screen cloth, material becomes loose after dehydration, and water content reduces.This squeezing machine compression ratio is little, and material squeezing effect is general, and the moisture content squeezing out can not be timely discharges from screen cloth, thus can not effectively reduce the moisture content of material after extruding, and then can not, for the final dry energy of saving, be unfavorable for reducing production costs.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of effective increase equipment compression ratio is provided, and can realize the reducing single-screw shaft squeezing machine that water of compaction is discharged in time.
Key problem in technology of the present invention is to drive the diameter of rotating shaft and the pitch of shortening helical blade to make its compression ratio become large by increasing discharge end, thereby make its squeezing effect better, its concrete technical scheme is: a kind of reducing single-screw shaft squeezing machine, comprise frame, drive unit, be arranged at feeding assembly and the discharge component at frame two ends, be arranged at the conical screen cage in frame and be installed in sieve cage and the coaxial driving rotating shaft arranging, described driving rotating shaft one end is connected with drive unit, on described driving rotating shaft, be provided with helical blade, described helical blade diameter diminishes gradually with conical screen cage internal diameter, it is characterized in that described driving rotating shaft diameter dwindling and become gradually large with sieve cage internal diameter, described helical blade pitch is with driving the change of rotating shaft diameter to shorten greatly and gradually.
The moisture producing in order to make to push is discharged as early as possible by screen cloth, and as a further improvement on the present invention, described sieve cage inwall is provided with one deck screen cloth, and sieve cloth is provided with osculum, and described osculum is for becoming from inside to outside large bellmouth.By becoming from inside to outside after large bellmouth makes water extruding see through aperture, can discharge very easily along its tapering.
As preferably, described conical screen cage is combined by 4 joint conical screen cage sections.
As preferably, described drive unit is motor and speed reducer.
As preferably, described driving rotating shaft is for being comprised of path section, changeover portion and large footpath section, and described changeover portion is the conical section changing from small to big.
Beneficial effect of the present invention: the present invention is by the improvement to driving rotating shaft and helical blade, and its squeezing effect significantly improves, and equipment water outlet is more unobstructed, the moisture content after material is extracted obviously reduces than original, has greatly reduced the follow-up required energy that is dried.

Specific implementation method
A kind of reducing single-screw shaft squeezing machine, comprise frame 001, drive unit 002, be arranged at feeding assembly 003 and the discharge component 004 at frame 001 two ends, be arranged at the conical screen cage 005 in frame 001 and be installed in sieve cage 005 and the coaxial driving rotating shaft 006 arranging, described driving rotating shaft 006 one end is connected with drive unit 002, on described driving rotating shaft 006, be provided with helical blade 007, described helical blade 007 diameter diminishes gradually with conical screen cage 005 internal diameter, it is characterized in that described driving rotating shaft 006 diameter dwindling and become gradually large with sieve cage 005 internal diameter, described helical blade 007 pitch is with driving the change of rotating shaft 006 diameter to shorten greatly and gradually.Described sieve cage 005 inwall is provided with one deck screen cloth 051, and screen cloth 051 is laid with osculum 511, and described osculum 511 is for becoming from inside to outside large bellmouth.Described conical screen cage 005 is combined by 4 joint conical screen cage sections.Described drive unit 002 is motor and speed reducer.Described driving rotating shaft 006 is for being comprised of path section 061, changeover portion 062 and large footpath section 063, and described changeover portion 062 is the conical section changing from small to big.
Its course of work is as follows: drive unit 002 drives and drives rotating shaft 006 to rotate, material enters from feeding assembly 003, drive helical blade 007 rotation on rotating shaft 006 that material is pushed to discharge component 004 through tapered sieve cage 005 from feeding assembly 003, along with material is constantly pushed forward, helical blade 007 pitch shortens gradually, drive rotating shaft 006 diameter also to become large thereupon, and the space of material in tapered sieve cage 005 also constantly diminishes, the moisture content that material is pressed tighter and tighter is wherein squeezed out gradually, and osculum is discharged on screen cloth 051, material becomes loose after dehydration, water content reduces.
