Description

Homogenizer for homogenizing flowable mass

Technical field

The utility model relates to a kind of homogenizer for homogenizing flowable mass, and this homogenizer has rotor and stator, and this rotor and stator have the gear teeth concentrically with respect to one another.

Background technology

Homogenizer in pharmacy, beauty treatment, chemistry and food industry for the manufacture of skin lotion, ointment, cream mud, mayonnaise and similar products.They are arranged on the bottom of mixer conventionally, and material mixes and be dispersed in this mixer.This homogenizer is configured to rotor-stator-disperser conventionally, but can be also so-called circulation stirring mechanism, to reach better pump, inhales effect.For example, by known this class homogenizer of DE 195 37 303A1.

Conventionally all materials to be mixed or to be homogenised were placed in advance before homogenization process in this container.But also may be essential, after only the part of one or several expectation being placed in advance, first start homogenization process, and in homogenization process, other part is added in compounding substances in batch or continuously.

Utility model content

The purpose of this utility model is, create a kind of device of aforementioned type, it can be simple and reliablely be sneaked into object in compounding substances or the contained thing of container, especially can also be the part (as powder, liquid, hot grease or similar object) that transmission is difficult to sneak into reliably.

The utility model has been realized this object in the following manner, this homogenizer has rotor and stator, this rotor and stator have a plurality of gear teeth concentrically with respect to one another, the plurality of gear teeth comprise the first rotor gear teeth, and, this homogenizer has for dividually two objects being transferred to the first transmitting device and second transmitting device of homogenizer entrance, wherein the first transmitting device radially leads in entrance in the inside of the first rotor gear teeth, and the second transmitting device radially leads in entrance in the outside of the first rotor gear teeth.

First explain several concepts of applying in category of the present utility model.

In category of the present utility model, homogenizer refers to, and application kinergety reaches the various devices of mixing and/or homo-effect.Homogenizer can be configured to rotor-stator-disperser, and first it change into dispersion effect (Dispergierwirkung) by strong shear energy and whirlpool energy the kinergety of rotor, and therefore realizes deep homogenizing.Due to this dispersion effect, this rotor-stator-disperser only produces relatively little pump and inhales effect, therefore may need high driving-energy.

Homogenizer has stator and rotor, among they can mutually relatively be placed oneself in the midst of and rotatablely move.Stator optimum position is fixed, and rotor is preferably rotatable, but this point is not that pressure is essential in category of the present utility model.If desired, stator also can reverse (for example towards rotor oppositely).In this important only having, rotor and stator can relatively rotate mutually, to reach below also by homogenizing and the dispersion effect described in detail.

Rotor and stator have the gear teeth concentrically with respect to one another.Concept " gear teeth " represents the rotor of extension in a circumferential direction or the aperture of stator wall, and compounding substances is penetrating in the radial direction these apertures outwardly when homogenizer moves.This gear teeth can have single aperture in wallboard other sealing, that along the circumferential direction extend, but these gear teeth consist of a large amount of axially extended tooth portion being arranged in the circumferential part section of rotor or stator conventionally, and these tooth portions have the impingement area for homogenizing material.If applied concept " axially " or " radially " in claim and description, axial direction always defines by the rotation of rotor.

The technique effect of the mutually concentric gear teeth below: the compounding substances flowing in the common axial entrance of homogenizer is caught by the radially interior rotor gear teeth, and impacts with peripheral speed according to the peripheral speed of these gear teeth.By centrifugal force (inhaling effect by the independent pump leaf of rotor or the pump of the wheel flank of tooth if desired), this material is thrown away outwardly, and encounter on the stator gear teeth subsequently with higher kinetic energy.The kinetic transformation of this material becomes dispersion effect.At the radially outer of these the first stator gear teeth, back to back is other the rotor gear teeth and the stator gear teeth if desired.

Conventionally also expectation, the kinergety of rotor not only converts dispersion effect to, but also convert pump to, inhales effect to carry homogenizing material.This point realizes by extra so-called pump leaf is installed on rotor, and these pump leaves have been realized similarly the pump of centrifugal pump and inhaled effect.But this pump inhale effect also can be extraly also or alternatively the surface of the corresponding formation by the rotor gear teeth realize.So, these gear teeth preferably have the surface towards inclined, and these surfaces have been realized pump and inhaled effect.

For transmitting dividually the described transmitting device of two objects, pass through the region of homogenizer entrance.This means, its hole that enters is arranged in such area of space, in this area of space at homogenizer run duration because the swabbing effect of homogenizer can produce pressure, this pressure is lower than the pressure in described transmitting device or conduit.

Concept " the first rotor gear teeth " refers to and is arranged on two rotor gear teeth between transmitting device seeing in the radial direction.Conventionally it refers to the radially inner most rotor gear teeth at this, but whether compulsory this is also.

Core of the present utility model is, transmits dividually these objects to be mixed mutually, and just in homogenizer, mutually mixes before disperseing.In order to promote this mixing, and especially for fear of transmitting device enter region in just mix in advance, by the utility model, by the first rotor gear teeth, described transmitting device is radially separated.Therefore, first the material radially transmitting within the first rotor gear teeth must penetrate these rotor gear teeth, it can with the object contact radially transmitting outside these gear teeth before.Because homogenizer was carried the compounding substances radial outward of transmission in when operation, thus by the utility model ground radially separately two transmitting devices can produce especially high security, to prevent that the material of transmission from returning in other transmitting device undesirably.If solid matter should be sneaked into flowable medium as in liquid as powder, this point is especially favourable.In this case, this powder is transferred in homogenizer by the first transmitting device of inner radial, and second transmitting device of liquid by radially outer is transferred in homogenizer.Because these two transmitting devices are by the radial separation of the first rotor gear teeth, and due to the powder of transmission and the conveying of the liquid radial outward of transmission, liquid can not returned in the region of powder conveyor, and therefore powder conveyor is pasted together, this is avoided forming powder block and the similar object that is difficult to dispersion again.The transmitting device for powder of this inner radial can keep bone dry when operation.Especially preferred, the transmitting device of inner radial only passes through the first rotor gear teeth and homogenizer in connection status, i.e. the amount of powder of all transmission must penetrate these the first rotor gear teeth and enter in homogenizer.To the outside of these first gear teeth, just there is the contact between powder and liquid in all liq amount all radial transport, in this region, powder has been experienced and accelerated and encounter in liquid phase with high kinetic energy by the first rotor gear teeth in such region.The kinetic energy of powder has promoted the processing of meticulous distribution in liquid phase, and avoids forming less desirable powder block.The low pressure producing in the entrance of homogenizer is responsible for pumping liquid and powder constantly.

The described the first rotor gear teeth are preferably configured to columniform, concentric with rotor axis wallboard, and this wallboard has the aperture that is arranged on its inside.It especially can have and protect by the known what is called of EP-A-0 988 887 (especially seeing Fig. 3 at this) Mechanical Builds that the gear teeth are the same.In category of the present utility model; these the first rotor gear teeth can also be born the function of the disclosed protection gear teeth in described EP-document extraly; protect homogenizer to prevent damage or the destruction of hard foreign matter; because this foreign matter is present in fixed substance to be mixed (as powder) conventionally; if and the clear span that is therefore arranged on the aperture of its inside in scope of the present utility model is less than the minimum dimension of foreign matter to be stopped, these foreign matters can radially be intercepted the inside of the first rotor gear teeth.With regard to details, please refer to described EP-A-document, its content is by reference to the content that also belongs to the application.

Aperture in the first rotor gear teeth can be configured to rectangle, and they can have conveying inclined-plane.The meaning of this concept " conveying inclined-plane " is, the wall in aperture is not accurately axially or in the radial direction to extend, but towards radially or axial direction tilt, therefore the powder penetrating not only accelerates in a circumferential direction, but also also experiences in the axial direction acceleration extraly especially radially outward, if desired.

The first rotor gear teeth have several centimetres or higher axial height conventionally.Preferably, the first rotor gear teeth see in the axial direction there are respectively at least two, aperture that preferably at least three rows are stacked setting.

This rotor can have pump leaf extraly, to also give the conveying effect that homogenizer is higher (pump suction effect) except dispersion effect.For example known from DE-A-34 17 242 and DE-A-195 37 303, this extra pump leaf is placed on the rotor of disperser.

Preferably, these pump leaves both radially extended within the first rotor gear teeth, also radially outside the rotor gear teeth, extended.So, pump is inhaled effect and be both applied to the powder radially transmitting in these gear teeth, is also applied to radially the externally liquid of transmission, and is applied on the powder/liquid mixture of generation.These pump leaves penetrate in this case the first rotor gear teeth and extend.

In addition the purpose of this utility model is this homogenizer of application, and solid matter is sneaked in flowable medium.This solid matter (especially powder) is transferred in homogenizer by the transmitting device of inner radial, and the transmitting device of flowable liquid by radially outer is transferred in homogenizer.Before the flowable medium of transmission, preferably homogenizer is put into operation.Thereby avoided before homogenizer operation or among liquid return in the transmitting device of inner radial, should be therefore that transmitting device of powder setting can keep dry.

The specific embodiment

By homogenizer of the present utility model, have axle 1, this axle is provided with wheel shell 2 and is driven by not shown driver.Rotor 3 is torsionally connected with this axle 1.Rotor 3 has two rotor gear teeth 4 and 5 concentrically with respect to one another.These rotor gear teeth 4 fingers first (inner) the rotor gear teeth.This stator is connected with homogenizer housing 6, and this stator has two stator gear teeth 7,8 concentrically with respect to one another.These two stator gear teeth 7,8 and the outside rotor gear teeth 5 have respectively axially the tooth portion of extending from rotor or stator, as concerning common professional.The first rotor gear teeth 4 are configured to the cylindrical wallboard that is provided with aperture 18, as especially appreciable in Fig. 3.

On the excircle of homogenizer housing 6, be provided with the passage 11 concentric with homogenizer axle 1, this passage forms the outlet of homogenizer.This outlet is connected with outlet stool 12.

This homogenizer has two transmitting devices that separate, i.e. inside the first transmitting device 13 (being preferred for powder) and the second transmitting device 14 of outside radially radially, and the latter directly had annular chamber 15 before the entrance of homogenizer.By two transmitting devices separately, therefore first the powder by inner the first transmitting device 13 transmission must penetrate the first rotor gear teeth 4 to annular wall plate 16, before it can contact with the liquid by the second transmitting device 14,15 transmission.

In order to improve transmission power, the rotor of homogenizer has pump leaf (seeing Fig. 2), and this pump leaf both radially extended within the first rotor gear teeth 4, but also extends outside the first rotor gear teeth 4.They have improved the transmission power of homogenizer, therefore in homogenizer entrance, have produced higher low pressure, and have therefore especially realized better powder suction.

As appreciable in Fig. 1, the top edges of the first rotor gear teeth 4 is extended in the recess of partition wall 16 or groove, and not having thus a large amount of powder can radially outward enter in homogenizer through the first rotor gear teeth 4.In fact, the amount of powder of all transmission has all been equipped with kinetic energy when penetrating the first rotor gear teeth 4, and it is easier that this kinetic energy can make evenly to mix in liquid phase.
