Description

Auto-feeding horizontal continuous charging centrifuge

The present invention be one be equipped with spiral feeder etc. make charging reach continuously, quantitatively, evenly, the automatic liquid-solid separatory centrifuge that can be suitable for various materials.

Horizontal continuous feed hydro-extracting cage (number of patent application 87205377.6) is though the energy continuous operation, raise the efficiency thereby reach, purposes such as energy savings, but its charge door is a common funnel, though material of different nature is entered in the machine by it smoothly, but it does not have initiative after all, only play constraint and guide effect to material, can only allow material self slide in the machine through it by characteristics such as its gravity, tend in the use produce and stop up, phenomenon such as pour into, though this phenomenon can be avoided under the property condition that hand stock has the people to look after and processing in time as far as possible, and be to avoid occurring this phenomenon just to need to the upper track charging process very strict requirement be arranged when in operatorless streamline, working, otherwise being not difficult, it is stifled to occur gushing, neglect and to wait phenomenon slowly suddenly soon and be directed at it and can not on automatic production line, base oneself upon, much less for the characteristic that adapts to different material makes funnel shaped changeable also is the thing of trouble, therefore, be incompatible only with the existing performance of hydro-extracting cage with the charging of funnel form.And; when a tractor serves several purposes; change the necessary sometimes clear of processed raw material, when shutting down, generally also want clout in the scavenger, and leaning on himself expecting to release under the rotation at a high speed; difficulty goes out only; therefore the also invalid usefulness of water flushing, must be provided with the water dumping bucket is not changeed; the structure that singly allows the spiral tube change makes it to go out fast in the clean machine material and can wash by water in the machine.

The present invention adopts the driven shaft of lengthening hydro-extracting cage, slow-revving screw feeding tube of suit and bearing material muzzle connect on the driven shaft of the first head of water dumping bucket bearing material, replace original funnel with this, make the charging of hydro-extracting cage reach quantitative, continuously, evenly, the material that extensively adapts to all kinds of different qualities, and the ability of inlet amount and centrifuge is complementary, make the work of centrifuge be in optimum condition always, selector fork is set in gear-box, make the spiral tube can obtain the ability of the action of rotation separately, on water dumping bucket and spiral tube, also do some each other changes to adapt to the various special requirements of different material with clout in the raising scavenger.

The present invention is made up of following several sections, the one, as the horizontal continuous feed hydro-extracting cage of foundation structure, but its driven shaft need extend to set up screw feed mechanism, also set up the gear shift structure in the gearbox, water dumping bucket and spiral tube also on demand situation increase some additional structures, these are all told below; The 2nd, screw feed mechanism, it is enclosed within the outer feeding tube of helical axis by the helical axis that is contained on the driven shaft, compositions such as the gearbox of drive helical axis and power.Helical axis is contained on the driven shaft through bearing holder (housing, cover), the one head is equipped with gear, with the gears engaged on the output shaft of gear-box, one of feeding tube is packed on the support, and the other end puts in the bearing material head of water dumping bucket, leans on one on support on feeding tube, have a bearing block that links to each other with support, buried bearing makes with helical axis and matches, and there is the supplied materials mouth top, feeding tube middle part, can join with funnel or charging line through this supplied materials mouth; The 3rd, according to the different requirements of different material dehydration, outside the water dumping bucket, wrap cloth, the net of different filter openings, and even fold up filter material such as fine sand, active carbon and curl, with this liquid that obtains peace and quiet liquid or have the different grain size particulate with iron wire; The 4th, according to by the characteristic such as sticky of water dumping material, rubbing board is installed on the spiral tube, do not make the sticky obstruction of filter opening to play, a material in the bucket is vertically stirred; The 5th, the differential gear in the differential gear housing is to both can be as the continuous charging hydro-extracting cage being made of two pairs of in-line gears of one-level transmission, also can be by secondary or multistage transmission by four pairs or many differential gear is constituted, with the differential scope of arranging in pairs or groups out wider, select required less or minimum differential for centrifuge with few gear; The 6th, on differential gear housing the installing shift fork one on the driving shaft in the case or several gears stir with obtain water dumping bucket and spiral tube with the duty and the water dumping bucket that change or not, the quick clear state of spiral tube list commentaries on classics.

Version of the present invention is to be the basis according to horizontal continuous feed hydro-extracting cage, driven shaft is extended, cover is loaded onto reinforced helical axis on the axle between gear-box and the water dumping bucket or between water dumping bucket and the rear support, both are independent of each other with each spinning of energy through the bearing supporting, having on the feeding tube that the helical axis overcoat can be by the charging aperture of dress funnel or feeding pipe, gears engaged on one gear and the output shaft of gear-box is arranged on the helical axis, and gearbox can be dragged through belt by motor, also can obtain power by the gears engaged of adorning on gear of adorning on the hydro-extracting cage driven shaft and the gearbox power shaft.The gear of the band commentaries on classics water dumping bucket in gear-box on the driving shaft can be from closing, when both mesh, hydro-extracting cage is in running order, just be in the clear state that spiral tube list changes during separation, use to water dumping bucket filter screen filter cloth should be decided with the need, can change solution at any time in the working site, the rubbing board of attaching on the spiral tube, one of its structural form can be at the double headed roller roller of a strap, and adorn two garden posts and be inserted in the post hole, guiding garden on the spiral tube, make the tendency that contracts in its generation at the interior stage clip that then is equipped with, just press to water dumping bucket inwall after having only the centrifugal force of acquisition, and spacing because of roller, make lath only slightly contact the effect that scrapes adherent material of playing with the bucket wall, certainly, for lath being packed into and the support force being arranged in scraper, need on the spiral of spiral tube, to dig short slot, for this strap for the purpose of the symmetry is answered two above symmetric arrangement with the setting-in strap.Sometimes also need clamping bristle etc. on the lath.

Operating principle of the present invention is as follows: the material that contains liquid enters charging door by pipeline or funnel, fall on the helical axis, the into bearing material mouth of water dumping bucket is taken away and pushed to the helical blade that is being rotated, material obtains centrifugal force once the water dumping bucket that enters the high speed rotation and flies to water dumping bucket inwall, can not allow material initiatively to stop on the oblique circle of bearing material mouth at this moment, and a straight barrel section that enters the water dumping bucket can be received by the blade on the spiral tube, slowly be pushed to the other end by it from one, in the propelling movement process, including liquid passes outside the filter cloth escape water dumping bucket because of centrifugal force leaves material, by case collection receipts and outside pipeline is sent machine, after the material that loses liquid that pushes to the other end is extruded the water dumping bucket, by case shelves collection after wind inhale, deadweight is fallen, modes such as hydro-extracting cage self wind goes out are discharged outside the machine.In this as the filter thing be that sizing just needs load onto rubbing board on the spiral tube, so that material is stirred and is prevented sticky filter opening in the machine, the feeding ability of this intermediate conveyor screw axle is by the size and the rotating speed decision of helical axis, as long as material foot, the feeding amount is fixed a number exactly, its amount of sending should be complementary with the pusher ability of spiral tube in the water dumping bucket, too much makes in the water dumping bucket material overstock that jam-pack or charging are very few to have influenced mechanical efficient in order to avoid feeding occurs.

The present invention is after being equipped with screw feed mechanism etc. on original horizontal continuous feed hydro-extracting cage, can make the charging of centrifuge reach continuous equal and quantitative, can cope with shifting events by sticking to a fundamental principle thus, satisfy the different requirements of various materials, can not occur gushing, phenomenon such as stifled, and can break away from people's treatment, admitted in the automatic assembly line and worked, compare with traditional vertical centrifugal machine, under same power, its work efficiency can improve more than ten times, and the full speed dehydration work that lid is planted for one to a few minutes because of vertical centrifugal machine not only needs doubly to the dehydration starting in man-hour, quicken and the braking process of stopping of stopping, and blowing, discharging is also very time-consuming, limited the performance of water separation capability own thus, and the present invention's hydro-extracting cage can be in the running at full capacity state always, thus can be than the vertical centrifugal machine conservation of power.When even this centrifuge is operated in hand charging, also can simplify the operation than vertical centrifugal machine, only need to get final product to anti-its fracture of material to funnel, alleviated labour intensity, reduced corollary equipment, reduced auxiliary material consumption, as long as possessing the pipeline of not scabrous feeding, discharge opeing, discharging etc. carries, just can be admitted in the automation production flow line at an easy rate, consciously work on line, the fluctuation at buffering input and output material two, and can not making trouble, this be vertical centrifugal machine can't imitate.And, aspect safety in production, this machine also has its original advantage than vertical centrifugal machine, because action of centrifugal force, even the normal speed centrifuge that separating factor is not too big, as on-stream generation fuselage damage parts fragment or machining object are thrown away, because of it has sizable destructive power at a high speed, and vertical centrifugal machine does not possess safety angle on horizontal plane except that upper and lower, much less what kill is that vertical centrifugal machine can not be accomplished unattended, therefore be directed at personal injury for avoiding that mechanical failure takes place, only take the insurance measure, equipment is taked regular retired method, therefore shorten the spendable time of centrifuge greatly, caused the waste of capacity of equipment.Horizontal centrifuge of the present invention not only on horizontal plane two of machine be safety angle, even therefore manually-operated, also safer at the charge door position, and take some simple measures, as a cover cap made from steel plate on the case outer cover at waist water dumping bucket position or simply build a heavy wall coagulation pedosphere hole, can not bring disaster to the miscellaneous equipment and the person even machine is damaged fly out fragment and material can be collected by thick shell institute shelves yet, but the retired time limit of proper extension machinery so, even can use till the disintegration at work of dying always, this is meaningful especially when being used for the corrosivity material, and the ability that it not only can make full use of equipment also can be equipment control and operating personnel bring the convenient and psychological safe relaxation of work.Thus, the horizontal continuous feed centrifuge of auto feed can its comparatively perfect performance, high efficiency, low energy consumption and higher characteristics such as automation lay the foundation for the existence of self.

Fig. 1. the outward appearance axonometric drawing of the horizontal continuous feed centrifuge that is depicted as auto feed when one of charge door is watched, be equipped with funnel (1) on the charge door among this figure.

Figure 2 shows that the outward appearance axonometric drawing that the horizontal continuous feed centrifuge of auto feed is watched from one of differential gear housing, feed pipe (2) is housed on the charge door among this figure.

Figure 3 shows that the structural representation of the horizontal continuous feed centrifuge of auto feed, it is made up of differential gear housing (3), water dumping bucket (4), screw barrel (5), screw feeding device (6), case (7), support parts such as (8), wherein except that screw feeding device (6) is newly-increased parts, other with former continuous feed hydro-extracting cage structural similarity, only local form is slightly different.

Figure 4 shows that the structural representation of screw feeding device; It is main the composition by helical axis (9) and feeding tube (10), helical axis (9) is sleeved on the influence that makes it not to be subjected to driven shaft (12) rotation on the driven shaft (12) through bearing (11), (9) one of helical axis are equipped with gear (13), locate to obtain power through gear (13) and (14), (10) one of feeding tubes are contained on the bearing block (16) that connects support through bearing and make it concentric with helical axis (9), feeding tube (10) other end puts in the bearing material mouth of water dumping bucket (4), feeding tube (10) is gone up has supplied materials mouth (17) towards the upper part, can be connected with funnel or pipeline.

Figure 5 shows that one of kind of drive of helical axis acquisition speed and power, gear on the helical axis (13) is driven by gear (14), the second-stage worm gear case (18) of driven gear shown in the figure (14) fits on the back seat (15), its power shaft is equipped with belt pulley (19), by motor drives, helical axis (9) with power and speed all obtain through the worm wheel gearbox transmission by motor.

Figure 6 shows that the another kind of kind of drive of helical axis acquisition speed and power, its power resources are in the gear (20) that is loaded on the centrifuge driven shaft (12), by the gear (22) on its drive two-stage worm gear box (21) power shaft, thereby the gear (13) that makes helical axis one obtains and centrifuge water dumping bucket, the power that the same motor of spiral tube provides, certainly the morphosis of gearbox needs to decide according to the helical axis working condition requirement, it can be that twin-stage worm gear speed change is to obtain bigger speed ratio, also can be that two single-stage worm gear case series connection are used, can also combine with worm wheel gearbox by gear graduation, but the source of its power nothing more than from gas-distributing motor and with the mode of same motors such as water dumping bucket.

Fig. 7 is that the axle of water dumping bucket is surveyed schematic diagram, it by the garden bucket circle (23) that is drilled with intensive hole on it cover garden hoop (24) gain in strength and shaped degree, (23) one on garden bucket circle has the bearing material circle (25) that has the bearing material mouth of garden frustum shape, there are shelves material rings (26) other end, garden bucket circle (23) is formed one through width of cloth bar (27) and axle sleeve (28) and bearing block (29), and can be loaded on the driven shaft by axle sleeve (28) and bearing block (29), less because of axle sleeve (28) diameter, can paste width of cloth bar (27) and paste weldering one garden ring (30) to increase fastness.

Figure 8 shows that the water dumping bucket holds the simple structure schematic diagram of filter material outward, at garden bucket circle (23) position bag filter cloth (31), outside filter cloth (31), wait filter cloth (31) encircling on garden bucket circle (23) again around iron wire (32), filtrate work is checked on by filter cloth thus, and the effect of fluid passage is only played in the hole on the garden bucket circle (23).Filter cloth and binding iron wire also can be substituted by other form in this, as wrapping in outside the bucket circle of garden with the cloth bag that sand, active carbon etc. are housed, then replace iron wire to tie up outside and just can make it to obtain salubrious clean filtrate, how to select filter material, be difficult to state to the greatest extent when deciding according to Technology Need with garden with holes hoop for barrel.

Figure 9 shows that on the spiral tube by the structural representation of adorning scraper plate, for needing on the helical blade (34) of spiral tube (5), to dig short slot by dress scraper plate (33), and load onto the guide pipe (35) of plug-in mounting scraper plate (33) at spiral tube two, the effect that scraper plate (33) inserts guide pipe (35) the compressed spring in back (36) makes scraper plate obtain the inwardly power of withdrawal, install etc. with convenient, scraper plate should two or more symmetries be installed.

Figure 10 shows that the organigram of scraper plate, it is scraped lath (37) two by one roller mount (38) is housed, dress roller (39) in the roller mount (38), and be inserted in the guide pipe (35) on the spiral tube (5) by lead (40), compressed spring (36) is held, when spiral tube (5) rotates at a high speed, the centrifugal force that scraper plate obtains can overcome the push-pull effort of spring (36) and outwards press to water dumping bucket inwall, and accept load with it by roller (39), scraping lath (37) at that time only contacts with water dumping bucket inwall, but do not produce big pressure, roller mount (38) contacts with water dumping bucket inwall, get rid of the material that adheres to because of centrifugal force on the bucket wall for striking off, its shape both sides as shown in FIG. has the bit structure, can adopt this structure to strengthen the effect of " scraping " too to scraping lath (37) certainly.

Gears engaged situation when the differential gear housing that Figure 11 shows that the one-level transmission is in normal dehydration work, gear (43) engagement on clutch gear (42) on the driving shaft (41) and the driven shaft (12), gear (44) and (45) engagement, this moment, motor was with alternation of hosts's moving axis (41) through belt pulley (46), changeed the water dumping buckets by two pairs of meshing gear bands and rotated with the spiral tube.

Gears engaged situation when the differential gear housing that Figure 12 shows that the one-level transmission is in fast clear material work, at this moment the clutch gear (42) on the driving shaft (41) leaves through the effect and the gear (43) of shift fork (47), light remains gear (44) and (45) engagement, the driving shaft (41) that this moment, motor changeed through belt pulley (46) band can only be taken turns (44) by pair of meshing, (45) band changes the rotation of spiral tube, and the water dumping bucket is not driven, and reaches very fast with this material in water dumping bucket is released by the spiral tube.

Figure 13 shows that the differential gear housing engagement situation map of 2 grades of transmissions, this moment is as long as suitably arrange in pairs or groups gear, just can obtain the bigger differential of excursion, for example, with substantially not under the situation of speed change, one group of gear (48), (49), (50), (51) modulus is m3, the number of teeth is 100,101,80,81, another organizes gear (52), (53), (54), (55) modulus is m4, and the number of teeth is 75,76,60,61, at this moment, when driving shaft that is to say gear (48), when (52) turning over 1000 commentaries on classics, gear (51), (55) rotating speed is difference slightly, and because of the collocation difference of 8 gears has different results, tabulation is calculated as table 1:

Gear number	（48）	（49）	（50）	（51）	(51) revolution	(48) revolution
							The number of teeth	100	101	80	81	977.88	1000
100	101	81	80	1002.48	1000
						101		100	80	81	997.53	1000
101	100	81	80	1022.63	1000
						Gear number		（52）	（53）	（54）	（55）	(55) revolution	(52) revolution
The number of teeth	75	76	60	61	970.66		1000
						75		76	61	60	1003.29	1000
	76	75	60	61	996.7		1000
						76		75	61	60	1030.22	1000

Like this with the spiral tube also be gear (55) should be slightly also be that the principle of gear (51) is arranged the rotating speed of last table gear (51), (55) as following table with size order faster than the water dumping bucket:

Gear number	（55）	（51）
			Revolution	1030.22	1022.63
1003.29	1002.48
		996.7		997.53
970.66	977.88

As can be known from the above table, its differential maximum can reach 52.34 changes, minimum has only 0.81 to change, then also have 6 differentials between the two, therefore, with the method, as long as do some the differential that change just can obtain various numerical value on the number of teeth, though the centre-to-centre spacing of two groups of gear mesh difference slightly in this method only for about half of the difference of both moduluses, is easy to revise with profile modified gear.

Figure 14 shows that the coagulation pedosphere shell structure schematic diagram of centrifuge accident prevention danger, it is by forming with the polylith baffle plate (58) at ground all-in-one-piece coagulation pedosphere hole (56) and hole, shutoff two, have on circle hole (56) several shape different sizes through hole (57) so that reinforced, the discharging of centrifuge, outlet conduit pass through, be embedded with bolt (63) on two wall in circle hole (56), so that mounting or dismounting baffle plate (58), bury installing plate (59) on the ground in the hole in advance underground so that centrifuge draw thereon slide into out and be packed in above.

Figure 15 shows that packed into the schematic diagram of work in the accident prevention casing of centrifuge, centrifuge moves in it and is packed on the installing plate (59) along installing plate (59), and feed pipe (60), discharge nozzle (61), outlet pipe (62) exported by on the hole on the circle hole (56) and the centrifuge each be connected, then the baffle plate at two (58) is loaded onto, the whole high speed rotating part that can make centrifuge like this is all by block.This brings convenience to production safety management, makes operating personnel that the sense of security preferably be arranged, even and the centrifuge accident that collapses loose and to fly fragment and water dumping thing, also can be stopped by firm concrete wall and baffle plate, can not enlarge the state of affairs.Facility just can prolong the length of service of centrifuge so thus, in addition directly use self disintegrate till.Reach with this and to make full use of equipment potential, certainly use for the maintenance of centrifuge with this facility and bring some inconvenience, but as add long mounting plate (59) length and become guide rail or simply on the centrifuge base, load onto wheel again, just can make centrifuge push-and-pull in the circle shell go out laborsaving the convenience.
