Description
Technical field
The present invention relates to a kind of propeller, especially a kind of novel interior empty pushing spiral propeller.
Background technique
Spiral propeller is the important component of horizontal type screw settling centrifuge, principle are as follows: rotary drum and screw propulsion
Device is rotated with certain differential same-directional high-speed, and material is continually introduced into conveying spiral inner cylinder by feed pipe, after acceleration enter rotary drum, from
Under the action of mental and physical efforts, heavier solid formation is deposited on formation sediment layer on rotatory drum wall, and helical blade is (i.e. dirty by the solid formation of deposition
Mud) be continuously pushed into rotary drum tapered end, through slag-drip opening discharge machine outside, lighter liquid phase object then forms internal layer pendular ring, by rotary drum
Big end overflow port continuously overflows rotary drum, through leakage fluid dram discharge machine outside, traditionally the helical blade on spiral propeller is all direct
It is welded on the outer surface of spiral core tuae, pressure suffered by this mode helical blade is very big, and solid phase is not only discharged
Object, it is also necessary in face of the hydraulic pressure of clear liquid, so, after centrifuge has been used long, weld between helical blade and spiral core tuae,
Can generate and split cross, it is serious will lead to spiral propeller and need to be disassembled from centrifuge repair.
Summary of the invention
The shortcomings that the invention solves the above-mentioned prior arts, helical blade pressure can be substantially reduced, make by providing one kind
Helical blade novel interior empty pushing spiral propeller with long service life, meets enterprise for spiral propeller service life
Demand long, at low cost.
The technical scheme adopted by the invention to solve the technical problem: this novel interior empty pushing spiral propeller, including spiral shell
Core pipe is revolved, one group of support rod along the distribution of spiral core tuae center convolution, spiral core tuae are fixed on the outer surface of spiral core tuae
Outside be equipped with helical blade, helical blade is weldingly fixed at each support rod, the inner end of helical blade and spiral core tuae
Clear liquid flow channel is provided between outer surface.Here the effect of support rod is that major part can be made to be forced through support
Bar is born, and the active force for the transverse load that helical blade is born substantially reduces, and since support rod arrangement quantity is more, institute
With the stress very little of single support rod is also very uniform, so as to greatly increase the service life of helical blade；Here clear liquid stream
The effect in dynamic channel is that solid formation is enabled to separately to be discharged with clear liquid, and clear liquid can be discharged by clear liquid flow channel,
(as shown in Figure 3) is discharged by the promotion of helical blade in solid formation.
It is further perfect, be provided in spiral core tuae one group respectively with the matched threaded hole of each post position, each support rod
Bottom be both provided with thread segment, support rod cooperates the junction of support rod and spiral core tuae at threaded hole by thread segment
Welding is together.Here the effect of threaded hole, thread segment is easily support rod to be fixed at spiral core tuae；Here it props up
The junction of strut and spiral core tuae, which passes through, welds the intensity that can be further strengthened between support rod and spiral core tuae, thus
So that support rod is able to bear stronger thrust load.
Further perfect, support rod includes bar one and bar two, and the cross section of bar two is greater than the section of bar one, helical blade branch
It supports the top in bar two and is weldingly fixed at bar one, thread segment is located at bar two.
The invention has the advantages that: structure of the invention is ingenious in design, reasonable, using support rod can make it is most of by
Power is born by support rod, and the active force for the transverse load that helical blade is born substantially reduces, and since support rod is arranged
Quantity is more, so, the stress very little of single support rod is also very uniform, so as to greatly increase the service life of helical blade；
Solid formation is enabled to separately to be discharged with clear liquid using clear liquid flow channel, clear liquid can be arranged by clear liquid flow channel
Out, solid formation is discharged by the promotion of helical blade, is worthy of popularization.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the a-quadrant partial enlarged view of Fig. 1；
Fig. 3 is the principle of the present invention figure.
Description of symbols: spiral core tuae 1, threaded hole 1-1, support rod 2, thread segment 2-1, one 2-2 of bar, two 2-3 of bar, spiral shell
Vane piece 3, clear liquid flow channel 4, rotary drum 5, solid formation 6, clear liquid 7.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings:
Referring to attached drawing: this novel interior empty pushing spiral propeller, including spiral core tuae 1, the outer surface of spiral core tuae 1
On be fixed with one group of support rod 2 along the distribution of 1 center convolution of spiral core tuae, the outside of spiral core tuae 1 is equipped with helical blade 3, spiral shell
Vane piece 3 is weldingly fixed at each support rod 2, is provided between the inner end of helical blade 2 and the outer surface of spiral core tuae 1
Clear liquid flow channel 4.
Be provided in spiral core tuae 1 one group respectively with the threaded hole 1-1 of each 2 location matches of support rod, the bottom of each support rod 2
It is both provided with thread segment 2-1, support rod 2 is cooperated at threaded hole 1-1 by thread segment 2-1, support rod 2 and spiral core tuae 1
It welds together junction.
Support rod 2 includes two 2-3 of one 2-2 of bar and bar, and the cross section of two 2-3 of bar is greater than the section of one 2-2 of bar, helical blade
3 are supported on the top of two 2-3 of bar and are weldingly fixed at one 2-2 of bar, and thread segment 2-1 is located at two 2-3 of bar.
The working principle of the invention: thing liquid mixture enters in rotary drum 5 after being accelerated by feed pipe (being not drawn into figure),
Rotary drum 5 and spiral propeller are rotated with certain differential same-directional high-speed, and under the influence of centrifugal force, heavier solid formation 6 is deposited on
Sediment layer is formed on 5 wall of rotary drum, the solid formation 6 (i.e. sludge) of deposition is continuously pushed into rotary drum tapered end by helical blade 3, is passed through
Outside slag-drip opening discharge machine, lighter clear liquid 7 then forms internal layer pendular ring, by gravity by clear liquid flow channel 4, then it is big through rotary drum 5
End overflow port continuously overflows rotary drum 5, and outside leakage fluid dram discharge machine (as shown in Figure 3), this mode, spiral propeller is transported in high speed
It changes a job when making, for main stress on support rod 2, the stress of helical blade 3 is relatively small, so as to avoid traditionally spiral
The case where weld between blade 3 and spiral core tuae 1 is easy to produce cracking can also be improved the revolving speed of spiral propeller, into
And it is more clean to enable to thing liquid mixture to filter, since revolving speed improves, centrifugal force is further strengthened, solid formation it is aqueous
Rate also will be greatly reduced, and be worthy of popularization.
Although the present invention has been illustrated and described with reference to preferred embodiments, this profession ordinary skill
Personnel are it is to be appreciated that within the scope of the claims, can make various variation in form and details.
