Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
Shown in composition graphs 1, a kind of cyclone of self-driven screw unloading, comprises overflow cap 5, overflow pipe 6, cyclone body, feed pipe 7, underflow pipe 12 and underflow mozzle 13.
Cyclone body adopts hollow structure, and its epimere 8 is in bar shape, and hypomere 9 is in cone-shaped.
Feed pipe 7 is connected to the upper lateral part of cyclone body and is communicated with cyclone body, and feed pipe 7 arranges charging aperture A.
The bottom of overflow pipe 6 extend into the inside of cyclone body, concrete, and this stretches into epimere 8 inside that position is positioned at cyclone body.The middle part of overflow pipe 6 is connected to the tip position of cyclone body, and overflow pipe 6 is communicated with cyclone body.
Overflow cap 5 is positioned at the top of overflow pipe 6, and the top of overflow pipe 6 is connected on the bottom of overflow cap 5, and overflow pipe 6 is communicated with overflow cap 5, arranges overfall B at the sidepiece of overflow cap 5.
Offer a upper gland at the top of overflow cap 5, arrange a upper bearing (metal) base above overflow cap 5, this upper bearing (metal) base is connected with overflow cap, such as with bolts.
Concrete, upper bearing (metal) base comprises top bearing cover 1, upper bearing (metal) 2 and top chock 3.
Underflow pipe 12 is positioned at the below of cyclone body, and underflow pipe 12 is connected to the bottom of cyclone body and is communicated with cyclone body.
Underflow mozzle 13 is in cone-shaped, and be positioned at the below of underflow pipe 12, underflow mozzle 13 is connected to the bottom of underflow pipe 12 and is communicated with underflow pipe, arranges spigot C in the following side of underflow mozzle 13.
Offer a bottom axis hole in the bottom of underflow mozzle 13, arrange a lower bearing base in the below of bottom mozzle, this lower bearing base is connected with underflow mozzle, such as with bolts.
Concrete, lower bearing base comprises lower bearing end cap 14, lower bearing 15 and step 16.
A rotating shaft 10 is set between upper bearing (metal) base and lower bearing base, this rotating shaft 10 is solid spindle, the two ends of rotating shaft 10 are supported by upper bearing (metal) 2 and lower bearing 15 respectively, upper bearing (metal) 2 is positioned by top bearing cover 1 and top chock 3, and lower bearing 15 is positioned by lower bearing end cap 14 and step 16.
Rotating shaft 10 runs through upper gland, overflow cap 5, overflow pipe 6, cyclone body, underflow pipe 12, underflow pipe conduit 13 and bottom axis hole from top to bottom successively.Rotating shaft 10 can freely be rotated.
The junction arranging the junction and rotating shaft 10 and underflow mozzle 13 that seal member 4,17 sealing parts 4,17 are respectively used to countershaft 10 and overflow cap 5 at upper gland place and axis hole place, bottom respectively seals.Seal member 4,17 can adopt the mode of filler to be formed.
It is identical with Air core diameter that the utility model gets rotating shaft 10 diameter, is namely generally
overflow pipe 6 diameter doubly, because rotating shaft 10 occupies the position of cyclone inner air post, thus inhibits the formation of air column.
Rotating shaft 10 is arranged with screw rod 11, this screw rod 11 is reducing varying pitch screw, screw diameter equals residing sectional position zero-speed enveloping surface diameter, screw rod 11 occupies inward eddy position, not only can reduce the possibility that bulky grain enters inward eddy, prevent overflow from running thick, and do not affect contour stealth smoothly from underflow discharge, do not disturb normal ore discharge.Variable-pitch propeller groove gradually broadens towards underflow pipe 12 direction, reduces spiral groove face resistance, prevents high concentration sand setting from compression and then blocking helicla flute occurring under groove face resistance and subsequent fluid impetus.
The length of screw rod 11 is the length of the cyclone body hypomere 9 of 0.3 times, more than this position is main effectively separated region in cyclone.Higher than this position, screw rod can disturb normal separation process, affects fine grained and enters overflow; Lower than this position, the possibility that the bulky grain after being separated enters overflow improves.
During installation in screw rod 11 two ends coaxial welding and rotating shaft 10.Because underflow pipe 12 place diameter is little, bulky grain slip easily blocks, and the bottom of the utility model design screw rod 11 is concordant with the bottom of cyclone body, bulky grain slip can be conducive to discharge from underflow pipe 12 smoothly by means of spiral fluted motive force.
Screw rod 11 rotates with rotating shaft under fluid forces, under spiral fluted stirs, accelerate coarse granule discharge from underflow pipe 12 and underflow mozzle 13 smoothly, reduce coarse granule enter inward eddy and be mixed into the possibility of overflow, not only high-concentration underflow can be obtained, also can reduce overflow runs thick, improves separative efficiency.
Preferably, above-mentioned feed pipe 7 and cyclone body, overflow pipe 6 and cyclone body, overflow pipe 6 and overflow cap 5 and underflow pipe 12 can adopt with underflow mozzle 13 and be welded to connect.
Preferably, above-mentioned cyclone body epimere 8 can adopt welded flange to be connected with cyclone body hypomere 9 and cyclone body hypomere 9 with underflow pipe 12.Its course of work is roughly as follows:
Material tangentially enters the epimere 8 of cyclone body by feed pipe 7 with certain speed, and to lower rotary motion in cyclone, under the effect of centrifugal force field, particle is because of its particle diameter difference realization separation, bulky grain overcomes the resistance of water to the motion of eddy flow wall, and under the acting in conjunction of self gravitation, moves under eddy flow wall screw, thin and little particle and the centrifugal force of most of water then because of suffered little, and near eddy flow wall namely do not do gyration with slip.
Under the promotion of follow-up feed, slip continues downwards and gyration, so coarse granule continues to concentrate to periphery, fine particle then rests on central area, and grain diameter is increasing to eddy flow wall by center, forms hierarchal arrangement.
When fluid flows through the hypomere 9 of cyclone body, due to the reduction of mobile section, cause radial velocity, pressure distribution uneven.Internal layer slip containing a large amount of fine particle changes direction, then moves upward, and forms inward eddy; Big particle then continues to move downward along wall spiral, forms contour stealth.Tiny particle is discharged from overflow cap through overflow pipe with inward eddy, becomes overflow; Under the effect of inward eddy forced vortex, screw rod is together with rotating shaft High Rotation Speed, and under the effect of screw rod, the high concentration big particle in contour stealth is discharged from underflow mozzle through underflow pipe along helicla flute, forms high concentration sand setting.So far whole separation process completes.
Certainly; more than illustrate and be only preferred embodiment of the present utility model; the utility model is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the instruction of this description; made all equivalently to substitute, obvious variant, within the essential scope all dropping on this description, protection of the present utility model ought to be subject to.
