Description

Modular vibrator

The present invention relates to a kind of modular vibrator, it is mainly used in mixing, the compacting and even of liquation, mixture, alloy, emulsion, suspension or the like.Here involve a kind of like this vibrator, the compressed air-driven that it sprays into by the runner along an axial distribution wherein has a concentric outlet in the lower area of runner, and it ends at a vortex systems.Force air-flow to make (vortex) of certain orientation by this vortex systems, make the rotor rotation that is positioned at housing thus.This vibrator can be as internal vibration device and outer vibrator simultaneously.

For example can see a kind of such vibrator by Swiss Patent document 221077, wherein existing can be around the free-moving rotor of a core.But this rotor is the rotary speed rotation to determine not, though because realize driving by the runner of slight inclination, this is the result of a chance.

Introduce a kind of vibrator in Britain data GB2010402A, it drives with compressed air or other compressed medias equally.This vibrator has a wing passage, and medium sprays into by this passage and is sprayed on a central shaft rotor rotated in internal system.But because have media outlet in bottom and upper area, the efficient of this vibrator is very low.

German utility model G8916150 announces a kind of piston type vibrator of compactness, and it is made up of a housing that has a cylindrical hole at least.The housing upper side is provided with one and is used for the hole of pneumatic fitting, produces motion so that be positioned at the rotor of enclosure interior.Here concentric distribution the in hole of the outer wall of housing and piston type vibrator inside, rotor moves in this hole.

Also have a large amount of vibrators except that above-mentioned prior art, they have a built-in motor on the other hand on the one hand as hydraulic vibrator work.But such vibrator can not be used for working stably, because the workload of their maintainings is very big, and often breaks down repeatedly.

Hydraulic vibrator can not be used in all places, because there is such danger, the fluid power drive medium of this vibrator can or flow out from vibrator from inlet or outlet, thus make to be mixed, compacting or and even article can't use.Hydraulic vibrator is made this form, and it has a cylindrical cavity, and for example a columniform basically unbalanced rotor can be in the rotation with one heart of its inside.Make rotor motion by the entrance and exit that drives liquid.Rotor must have blade in this case, because only in this way kinetic energy just can be used for driving.Here this infrastructure cost is very high, because for example blade must have definite radius of curvature, because blade must distribute along the direction of the beam that flows out from inlet flowing into end, distributes along opposite direction basically at outflow end.

Thereby also efficient cross section and the piston mass that depends on the hole of power in the piston type vibrator.Conclude thus, must adopt the big vibrator of appearance and size when big power has the vibrator of high efficient simultaneously again having.This causes simultaneously, not only requires a large amount of different housing and piston diameters actually, and have different length when same diameter.Usually the housing of vibrator because its part is processed as turning part, more or less has cylinder form.Here as having shown in the prior art, the cylindrical wall upper side of this housing is equipped with a pneumatic fitting at least.Because until 10bar or higher pressure work, must do quite withstand voltagely by pneumatic fitting with very high for this piston type vibrator, so housing needs certain minimum wall thickness (MINI W.), and pneumatic fitting is contained on this housing wall.Here the pneumatic fitting that normally constitutes by a tapped hole.

Known in addition unbalanced vibrator, it designs to such an extent that have a motor driver.They partly make the compact structure unit, but have only determined power simultaneously by frame mode uniquely here.Wherein transmission device and unbalance mass, are built in the housing together.But this vibrator maintenance workload is very big.

The objective of the invention is, create a kind of vibrator omnipotent, that help environment, it can be used for different application scenarios.It also must guarantee the application under extreme weather conditions except high efficient, can not have the work of maintenance ground in addition.

Task of the present invention solves by claim 1, and dependent claims is represented other structures by imagination of the present invention.

Therefore make modular vibrator and can be used for different application purposes, can be used for the mixing, compacting of liquation, mixture, alloy, emulsion, suspension and even or the like, particularly be used for the liquid cement of compacting.Here vibrator is made up of a housing, and it makes the turning part.By on the housing, preferably the joint on the axial end sprays into compressed air in the runner.This runner is distributed in the center of vibrator vertically, and makes a blind hole.This runner can be tapered in regional area at least except cylindrical structural, so that can compressed-air actuated eddy current not occur in flow field end thus.In flow field end is a concentric holes, and it ends at a vortex systems.This vortex systems is positioned at flow field end, and preferably by a worm screw shape path, it has only the helix of the little helical pitch of a circle.Here by adopting little helical pitch also to make the flow loss of drive medium air keep little amount, this conical distribution together with runner is brought significantly improving of this vibrator power, thereby impels the raising of efficient.Enter a cylindrical cavity at the terminal flow media of vortex systems, it is partly by columniform can filling up around the rotor that a core rotates freely.This rotor has a cydariform surface that outwards distributes, and this also improves the efficient of vibrator.Simultaneously very little in the gap of axial rotor, so that make flow loss keep very little thus.On the wall of the inner chamber that rotor can rotate cannelure is arranged inside, its bottom surface is made cydariform equally.Guarantee by this groove, in inner chamber, can not form dust, thereby make rotor also not have " vibration " tendency.Because can produce undesirable vibration thus, it for example to be mixed, compacting or and even article have disadvantageous consequence.

The appearance and size of vibrator keeps like this, makes it do very compactly.Wherein the external diameter of vibrator and length ratio are roughly the same.

Air by vibrator of the present invention enters with the air discharging area and can completely cut off by a silencer in addition.By adopt suitable silencer that the electromagnetic shaker environment is moved close and friendlyly, that is to say and avoid causing adverse effect to environment by noise.The way of current another environmental protection aspect that occurs is that a plurality of electromagnetic shakers interconnect, and that is to say cascade.For example the discharge air of passage first electromagnetic shaker, by vortex systems flows to next electromagnetic shaker by a flexible pipe that is connected on the above-mentioned silencer for this reason.All interconnective electromagnetic shakers are provided with corresponding silencer.Because the compressed air that passes first electromagnetic shaker is lost the fact of its active force, but spray into the new compressed air of unworn negligible amounts also so far of inlet input in second electromagnetic shaker, that be provided with a valve by means of one.This causes, for example new compressed air mixes with old compressed air before entering second electromagnetic shaker, therefore be again makeup energy to a certain extent, and second electromagnetic shaker shaken as first, this measure can repeatedly be carried out one by one, and show very significantly, except environmental-protection function, also reduce the energy cost of a plurality of electromagnetic shaker operations widely by such measure.

Silencer can be fixedlyed connected with electromagnetic shaker on the one hand, and it also can be connected with electromagnetic shaker with securing member replaceably by suitable connector in addition.

As shown, this vibrator can be used omnipotently, because must compacting in extremely different technical fields be in the material in the container.Here for example bulk goods may be related to, its volume need be reduced.Another big application is the field by the finished part of cement manufacturing.In order to realize quite high intensity level, in any case before cement solidification, need reach high density.Therefore in the completion cement member, be used for the distinct methods and the device of compacting liquid state cement.Here the branding of stamping vibration or shuttling movement for the compacting cement that is positioned at mould its objective is the shear stress of eliminating in the cement.Extrude the air that is included in the cement in this way, and make correspondingly compacting of cement.Wherein can for example apply motion for liquid cement by mold wall.This is called vibrations, vibration or vibration.This device that is also referred to as bumper is for example laid the mould that the inside comprises liquid cement.Bumper for example can be a complete platen, but part also can be placed in the bearing for this reason.At this bumper axis by the work of eccentric type vibrator principle by electronic, pneumatic, fluid power or also can drive by triangular belt.This needs to be used for the corresponding construction of this application scenario.Can make like this of the present invention.Simultaneously can reduce the application of cement, because reached the better compacting of cement.

By can shorten the dead time of cement products greatly by vibrator of the present invention.Therefore the cement plate that does not also parch fully can vertically or almost vertical position operate, for example so that it is flowed to its dry warehouse that can finally parch there.

The formation of this shape must guarantee an early stage shell certainly, because cement components is deviate from from mould under almost vertical state.

The Another application field of vibrator for example is the fluid ability that is emptied completely a container or keeps bulk goods.When processing and transport of loose cargo, be suitable for adopting this vibrator just.This can be in extremely different technical fields, wherein particularly medicine, food industry and prefabricated component manufacturing.

In order to make vibrator can be applied to all these fields, regardless of being in configuration aspects or all needing versatility aspect the operability by type of the present invention.Described vibrator has little weight, and in another housing of may packing in addition.The modular construction of another housing internal vibration device becomes more obvious owing to pack into.Here this second housing can weld or screw is connected on the structure.This structure can be a mixed container, a vibrating mould, a mould or the like.Because the structure of vibrator is preferably made the turning part, there are wearing and tearing hardly.Also because the guiding of the rotor that is formed from steel has correspondingly reduced wearing and tearing.Input according to the different air of application purpose also can be carried out intermittently.Consequently, vibrator can be different in order to the amplitude that vibrates.Both can also can correspondingly work by air inputted vibration device with low frequency with high frequency.Owing to obtain driving energy by compressed air, this vibrator also can use when low temperature.This with a kind of corresponding medium, is impossible in the vibrator that water or oil drive for example for example, and electrically driven (operated) vibrator can not be used in low temperature situation.

Figure by means of a possible embodiment is done more detailed explanation to the present invention.Wherein expression:

Fig. 1 is by the cutaway view of a vibrator;

Fig. 2 passes through the cutaway view of second housing of encirclement vibrator,

Being connected of the vibrator of Fig. 3 and more than 4 band silencers.

Vibrator shown in Fig. 1 is made up of a housing 1, and it makes cylinder, thereby as a turning part or a foundry goods.Seal by closing

cock

18 and 19 at axial end face.But closing cock 19 heart zone is therein made like this, makes it contain an inner part 20.The base plate 13 that inner part 20 is mainly abutted against on the closing cock 18 by a bottom is formed.Connect a vortex systems 6 on the base plate 13, it is provided with a helix 7.Core 10 is connected on the vortex systems 6.On the outside inner part 20 of vibrator a joint 4 is arranged, it is used for importing compressed air.Its center tap 4 has the runner 3 of an axial distribution, and it makes cylindrical in this embodiment.But also can do tapered according to runner 3 of the present invention.At the end of the runner 3 of making blind hole an outlet 5 that is used for drive medium is arranged.This outlet 5 is arranged on the bottom of vortex systems 6.From exporting 5 the air that flows out since helix 7 to a definite direction deflection.Air enters the inner chamber 2 within the vibrator thus.Air obtains certain vortex by vortex systems 6 thus, and it appears on the outer surface of cylindrical rotor 8.Make core 10 rotations of rotor 8 thus around vibrator.Also can from vibrator, discharge again for drive medium, be provided with one at least and discharge joint 23.

In order to raise the efficiency and avoid eddy current, inner chamber 2 inwalls are provided with a groove 9 with slight cydariform bottom.

Described in Fig. 1 with shown in vibrator since its structure can be used for different application purposes.It for example as shown in Figure 2, the housing 1 of vibrator can be packed within the cavity 21 there.Cover plate 22 sealings that this housing 11 of encirclement housing 1 preferably is connected by a usefulness screw 15 and housing 11 power and shape then sealedly.The apolegamy of housing 1 size is done accurately like this, and it can be matched with the interior profile 14 of housing 11.Be connected with shape with a device 17 power by screw 16 at the embodiment of Fig. 2 middle shell 11 sealedly.But except that screw 16, also can carry out housing 11 and the welding of installing 17.

Because this structure that is to say and is with one second housing 11, obviously, vibrator designs becomes modularization and can be applied to extremely different application purposes.This comprises, manufacturing cost drops to less, by adaptive accordingly, that is to say the structure of extremely different housing 11, the versatility that provides vibrator to use, the total of vibrator is designed to like this, and part can be changed apace, wherein vibrator integral body can not have the maintenance operation, thereby comprises consumable accessory hardly.

But Fig. 3 represents two cascades that are included in the vibrator in the housing 1, except the structure of selected two vibrators, in addition also in the corresponding way method connect more vibrator, make to form cascade.One adapter piece 25 is arranged on runner 3, and it passes from silencer 26.Silencer 26 is fixed on the housing 1 in this wise, make it not influence the vibration processes of vibrator, here can select screw thread or corresponding fixed type as fixture, on adapter piece 25, connect flexible pipe 24, by the work necessary energy of its input for the vibrator in the housing 1, just compressed air 29, discharge joint 23 at compressed air through its process after the vibrator and discharge from housing 1.If first vibrator back does not connect other vibrators, so almost the used compressed air of part is discharged from the air outlet slit 27 that is arranged in silencer 26.But setting up a function by a connection flexible pipe 28 from first vibrator to second vibrator in the embodiments of figure 3 connects.Therefore the compressed air efferent duct 30 that comes out from first vibrator is connected on the connector 25 of second vibrator.The compressed air through a vibrator no longer includes high like this effect, makes vibrator produce desirable rotation.On connection flexible pipe 28, a flexible pipe 33 is arranged for this reason, implement new compressed air input 31 for the compressed air efferent duct by it.One valve, especially check valve are arranged in flexible pipe 33 for this reason, and it prevents that compressed air efferent duct 30 from leaking unintentionally.Reach with first vibrator same effect together with the input of compressed air efferent duct 30 for second vibrator by compressed air 31, only be the first energy that needs much less for this, this makes the operation of this cascade vibrator reduce expense significantly.

In Fig. 4, can see with Fig. 3 in the same structure, just air outlet slit 27 directly is connected and discharges on the joint 23, just in order not cause other loss in first silencer 26.On second vibrator, just following among Fig. 4 adorns an exhaust hose on exhaust joint 23.
