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

A kind of reducing single-screw shaft squeezing machine
Technical field
The invention belongs to drying device field, be specifically related to a kind of single-screw squeezing machine for the mechanical mass such as maize germ, fiber extrusion dehydration.
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 material large to multiple water content has good dehydrating effect, for the final drying of material provides energy saving condition, greatly reduces dry total power consumption.
Existing single-screw squeezing machine is made up 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, axle has some blades, blade diameter changes along with the change of sieve cage internal diameter.Material enters from charging main part, drive unit drives helical axis to rotate, blade rotary extrudes 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 express material effect is general, and the moisture content squeezed out timely from screen cloth discharge, therefore can not effectively can not reduce the moisture content of the rear material of extruding, and then can not be the final dry saving energy, is unfavorable for reducing production cost.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of effectively increase equipment compression ratio, and the reducing single-screw shaft squeezing machine that water of compaction discharges in time can be realized.
Key problem in technology of the present invention is to drive the pitch of the diameter of rotating shaft and shortening helical blade to make its compression ratio become large by increasing discharge end, thus 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 on and sieve in cage and the coaxial driving rotating shaft arranged, described driving rotating shaft one end is connected with drive unit, described driving rotating shaft is 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 reducing and become large gradually with sieve cage internal diameter, described helical blade pitch shortens greatly and gradually with driving the change of rotating shaft diameter.
In order to make the moisture produced during extruding be discharged as early as possible by screen cloth, 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 become large bellmouth from inside to outside.By becoming large bellmouth from inside to outside, water extruding can be discharged very easily along its tapering through after aperture.
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 made up of path section, changeover portion and large footpath section, and described changeover portion is the conical section changed from small to big.
Beneficial effect of the present invention: the present invention is by the improvement driving rotating shaft and helical blade, and its squeezing effect significantly improves, and equipment water outlet is more unobstructed, material extract after moisture content obviously reduce than original, greatly reduce the energy needed for follow-up drying.

Fig. 1 is structural representation of the present invention.
Fig. 2 is the driving revolute axes configuration schematic diagram of Fig. 1.
Fig. 3 is the structural representation of sieve cage.
Fig. 4 is the osculum partial sectional view of screen cloth.
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 on and sieve in cage 005 and the coaxial driving rotating shaft 006 arranged, described driving rotating shaft 006 one end is connected with drive unit 002, described driving rotating shaft 006 is 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 reducing and become large gradually with sieve cage 005 internal diameter, described helical blade 007 pitch shortens greatly and gradually with driving the change of rotating shaft 006 diameter.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 become large bellmouth from inside to outside.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 be made up of path section 061, changeover portion 062 and large footpath section 063, the conical section of described changeover portion 062 for 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 the helical blade 007 on rotating shaft 006 to rotate material is pushed to discharge component 004 from feeding assembly 003 through tapered sieve cage 005, 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, material is squeezed out gradually by the moisture content of pressing tighter and tighter wherein, and osculum is discharged on screen cloth 051, material becomes loose after dehydration, water content reduces.
