Description

Pick up device with collecting granules shape material

Invention field

The present invention relates to a kind of device that picks up with collecting granules shape material, the present invention is directed to one type vacuum cleaner, for example to carpet or the Clean-floor vacuum cleaner of similar articles.But, the present invention is not limited to vacuum cleaner, and can expand to the device of removing particle from liquid, and the device of removing particle from gas, liquid or gas/liquid mixture.The present invention also can expand to piece-rate system, and this piece-rate system is not limited to use vacuum cleaner, but with the separating particles from fluid flows that rotatablely moves.The present invention will usually describe in conjunction with vacuum cleaner, and this vacuum cleaner can be family expenses, industrial or special-purpose vacuum cleaner.

Prior art

Vacuum cleaner produces swabbing action by means of fan, and this fan discharges a powerful air stream at the casing rear portion.This just forms strong air inlet stream, and this air inlet stream carries any dirt particle that catch on the carpet that applies from suction nozzle or floor.Fan has a large amount of blades that are provided with along a certain angle, and the rotation of fan axially forms air stream along it.This circulation of air is crossed one bag, and dirt deposits in bag and collects and air stream be there is no brightly and hinders.

A shortcoming of vacuum cleaner is that the volume of the air of its whole volume will enter the dirt accumulation chambers and must pass the wall of dirt pocket.Overfill or obstruction if dirt pocket becomes, the efficient of vacuum cleaner will reduce, and may cause vacuum cleaner itself to damage.

The efficient of vacuum cleaner depends on air velocity and two factors of air-breathing power.Air-breathing performance is the product of this two factor.Therefore, inspiratory force is low when flow velocity is maximum, otherwise flow velocity was low when air-breathing power was big.Vacuum cleaning is confidential effectively to work, must inspiratory force and flow velocity suitable.

Another shortcoming of traditional vacuum cleaner is that the flow velocity and the flow of air stream is lower.Determined the efficient of vacuum cleaner to a great extent along carpet or ground and the air velocity that enters the vacuum cleaning head.Therefore wish high-speed air and a large amount of air.

Other shortcoming of vacuum cleaner is the power consumption that motor is higher, surpasses 1000kW usually and just is difficult to make battery powered vacuum cleaner; And the efficient of fan is low.

I early stage patent application WO97/08983 has introduced a kind of vacuum cleaner, this vacuum cleaner has CLB, fluid can circulate around CLB, CLB has the bottom, during using, this bottom is suitable for the contiguous district that vacuumizes, this bottom be dimensioned to the surface that a lower pressure is provided, CLB also has top, this upper dimension is designed to provide a high pressure surface, the fluid accelerator is used near the fluid the acceleration curve body, and the fluid flow splitter is arranged on the top of CLB, is used for fluid stream is partitioned into recirculation portion, this recirculation portion continues motion around CLB, and the discarded part that enters the dirt accumulation chambers is discharged from accumulation chambers.

The shape of CLB can be annular or volution shape (toroid).CLB needn't be symmetrical, and its cross section can omit ovalize.CLB is not whole to be shaped form, and the part of CLB can be straight line if desired.When using vacuum cleaner, fluid stream is cut apart device (splitter) fluid is divided into recirculation portion and waste part.The air that enters waste part need be discharged through last blast pipe, and this blast pipe can be used in combination with a screen pack.

The shortcoming that vacuum cleaner may exist is that removing particulate matter from waste streams is by the air velocity degree is descended particulate matter to be fallen to collect in the basket.For the separation of subparticle material, this is always not effective.In addition, the air of a great deal of still must be discharged through the vacuum cleaner top.

Known can be by means of making fluid rotation from fluid stream separating particles, and remove particle with centrifugal force.Industrial separation machine (cyclone) just uses this principle.But, existing this type of seperator is also not really effective, if particularly require the seperator size very little, and needs to separate very little particle.Based on this reason, these seperators are not for example succeedd aspect the vacuum cleaner in numerous applications commercial as yet.

Another shortcoming of all known vacuum cleaners and rotary seperator is that gas after the cleaning or liquid stream are discharged from device.This makes that this device is not suitable for requiring to discharge the occasion that emanation (exhuast emission) is minimum even do not have.For example, have it is found that of allergy problem, the effluent of discharging from cleaning device can cause allergic reaction.Hospital and other toilet find from the effluent that cleaning device the is discharged pollutant that still spues to air.

Preferred forms

Referring to Fig. 1 cutaway view, the chief component of diagram vacuum cleaner 10 comprises: shell 11; Air inner cycle channel, this passage comprise interior circular passage 12, outer ring passage 13, annular kerve 14; CLB 15 is arranged in the groove; Last separation chamber 16; Fan-type air accelerator 17; Motor 18 is used for drive fan 17.

Vacuum cleaner 10 available metals, plastics, composite or other suitable material are made.Vacuum cleaner is quite little, the about 40cm of its diameter, highly approximately 40cm.Nature can be imagined greater or lesser vacuum cleaner according to user demand.11 have the recirculation air passage in the vacuum cleaner shell, and arrow shows the general direction of air draught among Fig. 1.Fan 17 can be the described design of International Patent Application PCT/AU93/00581.Fan 17 has the blade 20 of wheel hub 19 and several extensions.Fan 17 is with at a high speed rotation, make air with high-speed downstream to interior circular passage 12 and flow to groove 14.The width of groove 14 is (but this numerical value can change as required) between 5mm to 20mm, is arranged on vacuum cleaning motor spindle and the contiguous floor surface 21 that is vacuumized.Cannelure 14 is limited by the bottom 22 of shell 11 and the bottom 23 of motor casing.Nature, bottom 23 need not be the parts of motor casing and can making separately.Be arranged on and be loop curve body 15 in the cannelure 14.Loop curve body 15 is divided into two branch grooves with groove 14, promptly interior groove 24 (blowing groove) and the outer groove 25 that divides of dividing.The foot of CLB 15 inwardly from a segment distance, when the vacuum cleaner is placed on the floor 21, forms a little gap from groove like this between CLB 15 bottoms and floor 21, this gap can pass through air stream around CLB.

CLB 15 has last ring part 26, this ring part extend upward and towards the separation chamber 16 bottom, circular passage 12 and outer ring passage 13 in this ring part plays a part to separate.Ring part 26 is arranged to contiguous fan blade 20, when rotating in ring part 26 with permission fan blade 20, makes the outward flange of fan blade 20 and the inwall of ring part 26 have excellent contact.Like this, this part of ring part 26 plays the barrier action of fan 17.

When fan 17 rotated with high speed, air was through passing through fan, and to pass through interior minute groove 24 at a high speed, this interior branch groove can be considered an annular and blows groove.By means of blowing by blowing groove, air attaches CLB 15, and will flow with the CLB surface by means of wall attachment effect.When air with at a high speed by blowing groove and around the foot of CLB 15, air picks up around the CLB 15 such as particulate materials such as dust or dirts, and carries these particulate materials around CLB 15 and upwards enter outer ring passage 13.

Outer ring passage 13 is taper, and it is narrower that this taper end diametric(al) broad under the adjacent grooves 14 becomes the upper end diametric(al), and this circular passage is communicated with the bottom of separation chamber 16.By means of this taper, along outer ring passage 13 air flowing streams be forced to the per minute rotating speed that increases in the shape of a spiral line pass through the circular passage.In other words, when the particle that enters air stream upwards passes through passage 13,, also advance with more and more higher per minute rotating speed by helix in separation chamber 16 advances process.Screw action can obtain promoting that this deviation device is a kind of knuckle element by deviation device 30 is set in passage 13, for example geosynclinal convex sheet or blade, and these elements make air stream become the helix air-flow.

Make outer ring passage 13 bottoms of this first embodiment has spherical increase portion 31, and this increase portion forms the part of first collecting region.At this collecting region, the larger particles 32 that is inhaled into separates from the air stream that moves upward by means of himself bigger quality, and falls into collecting region 31 so that remove subsequently.

Before increase portion 31, outer tunnel is narrower to fall so that form pressure in outer tunnel.This pressure falls and makes air stream have the trend of pushing the speed.Deviation device 30 promotes the air circulation to be converted into helical flow, thereby can gather way.

Smaller particles 33 still is carried in the helical flow that moves upward.Separation chamber's 16 bottom openings are crossed in circulation of air, make spiralling at the air stream of opening part with higher per minute rotating speed.In case enter separation chamber 16, smaller particles 33 rotates air stream, and by the opening 34 on the wall around the separation chamber 16.Pass opening than granule and enter second collecting region 35.In this district, the speed of air stream descends, and can impel air velocity to descend by means of at collecting region the baffle plate (not shown) being set, and the decline of air velocity degree makes than granule 33 whereabouts and rests in second collecting region 35.Spirality rotary air behind the separated particle flows to the roof 36 that reaches separation chamber 16, and spirality inwardly flows to the top of interior circular passage 12 downwards.The spirality air stream that label 37 expressions are downward.Interior circular passage 12 has top end opening 38, and this opening is communicated with the bottom end opening of separation chamber 16, but inside at a distance of a segment distance with outer ring passage 13.

By means of this set, enter air 16 rotations of separation chamber 16 from outer ring passage 13, and be forced to adapt to spirality 37 motions of deflation around the separation chamber, at this moment, this air enters inner cycle channel 12 by fan 17 downwards.Because air stream is taked the spiralling than minor diameter (tighter), air stream will be with higher per minute rotating speed rotation, this helps to make trickle rotation outwards, and subparticle will become separation chamber 16 in subsequently and be entrained in (attention: the viewing angle that upwards depends on the observer) in the air that stays that spiral rotates up.Like this, avoided dust to return through passing through fan or fluid drive apparatus.Only superfine particle passes fan and returns, and does not weaken the function of cleaner on a large scale.

Be auxiliary cleaning action, also in order to make the minimum of carrying secretly of outside air, 14 places are provided with opening 40 at next-door neighbour's groove.Opening 40 can be the form of hole array or makes cannelure.

Air stream down to interior circular passage 12 divides some air go out, and passes opening 40, and this division air portion has on floor 21 blows so that the loose effect of particulate material at a high speed.In addition, divide the air portion that and to be carried secretly by the air stream that stays that flows around CLB 15, this means and pass groove seldom being with or without extra air.Therefore, do not need outlet (vent) to discharge gathering of any pressure at collecting region, it is because the outside air that is entrained in the fluid stream causes that this pressure gathers.If there is some air to be entrained in the fluid stream, and outlet need be set, and these outlets can be made into very little, and can a kind of utmost point effective filter cover, this filter is not useable for traditional vacuum cleaner, and traditional vacuum cleaner must discharge a large amount of air.

Flow through the fluid in hole 40 as a kind of injection stream bump carpet, floor or ground.This makes particulate matter loose.Then, along with the speed of fluid reduces to zero in essence, air is not flowing in a flash.This just makes the instantaneous rising of static pressure, and fluid stream rushes at low-pressure area, and this low-pressure area is caused by the wall-attached jet that flows out from groove 24.What wishes to take away from the high-speed jet of groove 24 ejections like that to any jet.In the case, it carries from the hole 40 fluids of discharging secretly, and any a large amount of air outside the entrainment device not.

Fig. 3 shows the present invention's second embodiment.In this embodiment, fan 50 is apart from cannelure 51 1 segment distances.In addition, the present invention works in a similar manner.For example, in the vacuum cleaner shown in Figure 3, fan 50 quickens air stream, flows to cannelure 51 by an inner tubular passage 52.Cannelure 51 forms with outer ring passage 54 walls by means of conical plug 55.Loop curve body 55 is arranged in the groove 51, and also slightly inwardly at a distance of a segment distance, like this, air can blow into outer tunnel 54 by near the groove 56 that blows CLB.

As described in Figure 1, the groove 56 in the neighborhood graph 3 also can be arranged in hole 40, and is but, also not shown among the figure.The following view of pick-up head shown in Figure 3 is similar to view shown in Figure 2 in essence and has hole 40.

Cutting line 57 illustrates cannelure 51 and can be any distance easily apart from fan 50.Outer tunnel 54 also has: the first annular collecting region 62 is used to collect heavier particle; Separation chamber 58 makes subparticle rotate to be similar to reference to figure 1 described mode in this separation chamber.Before collecting region 62, channel narrows is fallen to form pressure, and this pressure falls the air velocity degree is raise.Air can help the air rotation with turning device when passage moves.

Separation chamber 58 also has opening 59 on sidewall, particulate matter can and enter second accumulation chambers 60 by this opening.In the use, circulation of air passing through fan 50, herein, air is accelerated and so that being pushed through annular blows groove 56 at a high speed, around CLB 55, rising enters outer tunnel 54, pass outer tunnel 54 and enter first collecting region 62, at this, heavier particle leaves air stream.Air stream continues by passage 54 and enters separation chamber 58, and in this process, passage 54 tapers inwardly, and this makes air stream increase the per minute rotating speed.The rotation in separation chamber 58 of air stream, when it arrived outer wall 61, the air spirality spiraled littler annulus, to return the air inlet that enters internal channel 52 and to pass fan 50.

Fig. 4 A and 4B show the used corner attachments of vacuum cleaner.The plan view of corner attachments 80 is roughly triangle (seeing Fig. 4 B), and has two straight lines outside, 81,82 and one shaped form inner edge 82A, the outer curve complementation of this inner edge and vacuum cleaner wall.A pair of gas flow tube 83A, 83B extend through hole 95,96, and this pipe has the end 84,85 that protrudes into internal channel 12, and a spoonful shape is made in this end, flow by pipeline with a part that promotes air stream.The other end 86,87 of pipe has lower opening 88,89, and when corner attachments was in position shown in Fig. 4 A and the 4B, this opening was closed.(nature, the quantity of pipe and size may be changed).Corner attachments applies bias voltage by spring 90, and this just allows corner attachments is pushed against on the outer wall of vacuum cleaner.At this moment, pipe 83A, 83B are further pushed hole 95,96, and the opening 88,89 of pipe is communicated with hole 91 now, and this hole itself is communicated with the chamber 92 with one group of bottom aperture 93.

When the bias voltage of resistance spring 90 during with corner attachments 80 backup vacuum cleaners, pressure-air can be along pipe 83,84 hole 91 inlet chambers 92 of flowing through, and arrive at ground to collect dust and dirt particle by aperture 93.Recurrent canal 97 is communicated with outer tunnel 13, but only is communicated with when corner attachments 80 is made progress the backup vacuum cleaner.

Should be pointed out that pick-up head needs not to be annular in plan view, can be any suitable shape in plan view.

This vacuum cleaner has many advantages.Low disperse or do not disperse by means of it, this vacuum cleaner can be used for the gnotobasis such as hospital.This vacuum cleaner can be used for picking up and collecting deleterious particle, and any particle that reduces or cannot discharge from vacuum cleaner.Motor 18 can be cooled off by the ventilation (not shown) of the vacuum cleaner of flowing through, but the air of the ventilating opening of flowing through does not mix with any circulating air.Air stream process is around behind the CLB 15 shown in Figure 1, and the airflow path cross section increases, and air per minute rotating speed is lower, to help removing bigger particle 32.Passage is tapered subsequently so that cross section narrows down, and therefore increases the per minute rotating speed of air.

Should be pointed out that liquid can be picked up and collect in the mode identical with the mode of drawing particle by this vacuum cleaner, as long as motor and liquid are isolated, can not damage system.

The essential characteristic of this vacuum cleaner is, only discharges micro-air on the one hand or does not have air to discharge, and also discharges without any other fluid on the other hand, and this kind vacuum cleaner is not limited to the as above mentioned family that only is suitable for and uses.The device of some form can be immersed in any liquid such as water and work to remove particulate matter from liquid.The recirculation of fluid is to carry out in internal system in essence, does not need from drawing extraneous fluid on every side.Therefore do not have or few fluid is discharged from system, can be described as closed circuit system in essence.

Be full of the particle in water or any liquid, this of available certain form kind of device is handled.No matter attached wall pick-up head (Coanga pick up head) is arranged to apart from motor and fan or other fluid accelerator one segment distance, still extremely near them.This loop is worked, and most of dirt and other particulate matter can remove by means of any device, but recommend to use vortex device described herein (vortex).Need in circulation for the first time, not remove the particulate material of each sheet remainder, because their circulations once more, and do not return surrounding environment subsequently.

A kind of Variant Design of the present invention can be immersed in the swimming pool, to separate and collecting granules shape material from water.

Fig. 5 shows the vacuum type cleaner according to further embodiment of this invention.In this embodiment, the bottom of vacuum cleaner is similar to the explanation of being done with reference to figure 1, and therefore similar part is with similar numeral.For example, vacuum type cleaner shown in Figure 5 also has: shell 11; Inside air recirculation passage, this passage comprise interior circular passage 12, outer ring passage 13, annular kerve 14 and are arranged on the interior loop curve body 15 of groove.The fan 17 that is driven by motor 18 is provided with in the enclosure.Loop curve body 15 is divided into two fens grooves with groove 14, blows groove 24 and water jacket 25 in promptly.Fluid, for example air is quickened with the inside groove 12 of flowing through downwards, around CLB 15, also upwards by water jacket 13 by fan 17.Be minor air cell 110 on fan 17, this minor air cell is arranged to U-shaped.The air that comprises dust or other granular materials makes progress from passage 13, and owing to the cause with reference to figure 1 illustration, air is for the helical movement.Air enters minor air cell 110 through air inlet 111, the wall of the contiguous minor air cell 110 of this air inlet.Air forms eddy current 112 in minor air cell 110, this eddy current forms larger-diameter eddy current at 110 wall places, contiguous minor air cell.Eddy current flow is 110 shaped form path and enter collecting region 113 through the minor air cell.Subsequently, eddy current forms second eddy current 114 (eddy current in claiming again) than minor diameter, and eddy current moves near eddy current 112 middle parts outside returning in this, to return by fan.Gravity helps to make dirt and particulate matter remain on the bottom of collecting region 113.Collecting region 113 can be that a kind of this collar is detachable with collar 115 fastening removable chamber or cup, so collecting region 113 is removable and with its emptying.Collar 115 can be installed with traditional method, for example available be threaded or be provided with connect bayonet socket and connect the two portions together.

In order to make larger particles at last in collecting region 113, spherical increase portion 31 has than increase portion small cross section among Fig. 1.This help with more greatly, heavier particle 110 upwards washes away along the minor air cell through passage 13, and enters collecting region 113.So by means of forming stronger eddy current, this can more easily realize.In Fig. 5 and 6 illustrated embodiments, passage 13 does not need to slope inwardly, but at any point, particularly may be outward-dipping or take other setting in the porch that enters 110 tops, minor air cell, so that help heavier particle upwards to advance with eddy current.

Minor air cell 110 does not need to being U-shaped or around 180 ° shaped form accurately as shown in Figure 5.For example, consider that from certain convenience, how much requirements and actual needs the wrapping angle of curve part can be littler or bigger.Any type of setting can realize, if two kinds of eddy current of formation, promptly outer eddy current and interior eddy current, the direct of travel of interior eddy current is opposite with outer eddy current direct of travel.

Referring to Fig. 6, the figure shows the described device of a kind of Fig. 5 of being similar to, only comprised pipe 116.This pipe is arranged to the middle part that the one end is in the minor air cell in essence, and its other end is in collecting region 113, and the end wall of contiguous minor air cell (minor air cell is configured to extend along collecting region 113 whole bottoms).The pressure at eddy current middle part is a little less than the pressure near the eddy current neighboring.In Fig. 6, be provided with dirt-collection bag 117 in the collecting region 113, for example a kind of translucent thin bag.Pipe 116 is being right after the inboard lower pressure that generates of collecting region 113 walls.Like this, although the whole system internal pressure is lower than atmospheric pressure, pipe 116 makes bag inhale the wall that leans on collecting region 113 by means of the lower pressure that generates.Pipe 116 may not need, because can have low-pressure area at the highest inwall place of adjacent fluid speed.This makes that bag keeps opening, so eddy current can rotate in bag.Collecting region 113 can unload subsequently and bag taken off and take away or clean.

The bag 117 of polybag or other type can keep by means of frictional constraint, promptly by means of O type circle or similar device in the collar 115, the weight of dirt particularly is close to the remainder of bag with the bottom in the chamber of representing locular wall with label 119, this bottom can have the groove or the rib of Any shape, like this, the bag top of contiguous collar 115 keeps static relatively, and the remainder of bag bottom rotates with rotatable, knock-down collecting region.

Like this, as required the number of times rotation in essence of the top of the bag of plastics or other material, and break away from collecting region 113, and the neck of dirt-collection bag is reversed the dirt that has bag bottom with sealing.Like this, the collecting bag that unloads fully can propose collecting region, and it is tightened makes dirt and atmosphere isolated fully (seal).If dirt-collection bag is a Biodegradable material, it can be buried or burns subsequently.

Further improvement of the present invention is that in case collecting zone rotatably breaks away from, the air path of process pipe 116 also disconnects, and because of being further rotated, the hole or the path that lead to atmosphere are opened.In the case, if vacuum cleaner allows operation when described disengaging, will form significant pressure differential outside the collecting bag in collecting region 113 and between the dirt-collection bag inside.Like this, bag will wrap tightly on the dirt that is closed and push down it, and subsequently, owing to further break away from rotation, the dirt in the dirt-collection bag will be found becomes the more form of compression, and same the binding in removable bleed top can produce as mentioned above.

Get back to Fig. 3, it is pointed out that the device of form shown in Figure 3 also can have feature described herein, its accumulation chambers 62 and groove 59 the same being cancelled, the outer wall of minor air cell 58 can extend to any distance along any direction.It need not be around 180 ° curve and only around 90 ° or other angle, as long as can the picture mode consistent move with said mode, that is, it can have to use and is threaded or bayonet socket, the rotatable disengaging of collar, can comprises a dirt-collection bag and can make dirt remain on the bottom of accumulation chambers by means of gravity.

Need point out that also embodiment illustrated in fig. 3 have a handle, this handle can illustrate at the topmost of figure, but does not illustrate as a kind of cartridge type vacuum cleaner, can use on the floor.Passage 52 and 54 can have flexible wall, for example the flexible pipe in flexible pipe.The cross section of spherical region 62 can reduce.Accumulation chambers 62 and groove 59 the same being cancelled, and because the minor air cell 110 among Fig. 5 and 6 faces down, the minor air cell need not have above-mentioned sweep.In fact straight line shown in it still can be and still can have same feature.In fact, increase be threaded or the bayonet socket collar so that a part breaks away from respect to the other parts rotation, increase and be arranged on inner dirt-collection bag, and all other feature as among Fig. 6 shown in pipe 116.
