Background technology
This mixer can be used to mix different materials to be mixed, especially for the combination construction material blends, and for example plastic mortar or concrete mixture.The mixer axis substantial horizontal of this mixer is extended, and makes in mixing chamber, and material to be mixed is being transferred along mixing axle on vertical direction during the married operation.Mixing chamber is limited by columniform mixing channel inner surface basically usually, that is to say that groove inner surface and mixer axis coaxially extend, and under normal conditions, groove inner surface circumference all is identical on each axial location that mixes axle.Two end faces at the front and back place of mixing channel inner surface are usually designed to flat.This mixer structure for example be described in detail can the REFERENCE TO RELATED people EP 0 229 328 A1.
Mix axle and be rotatably installed on the both ends of the surface of mixing channel, and place rotation by the driver that is arranged on the mixing channel outside usually.Hydrid component is fixed on predetermined spacing and mixes on the axle, hydrid component is together with mixing axle around the rotation of mixer axis, and always comprise one and mix arm, in mixing chamber, be used to carry one or more hybrid elements of material to be mixed to be fixed on this mixing arm.Usually, hydrid component be designed to blade shape and with respect to the surface line parallel of mixing channel with the mixer axis with an angle setting, make material to be mixed stand a motion vertically.They have at least one scraping edge, and this scraping edge is adjacent with the mixing channel inner surface and be used for collecting material to be mixed, and these materials lean against on the groove inwall.In this case, the distance from the mixing channel inner surface to this scraping edge is as far as possible little; The layout that a kind of edge of wherein swiping leans against on the mixing channel inner surface is preferred.Damage for the mixing channel inner surface that for example prevents to cause by the material granule to be mixed of catching, the scraping edge is preferably made by the material softer than mixing channel inner surface, plastic material particularly, polyurethane for example, and the mixing channel inner surface is normally made by hard material, for example pottery or hardened steel (hardox).
Each hybrid element of hydrid component can be made of a variety of materials, and for example, the core body of harder can be centered on by the wearing and tearing body, and this wearing and tearing body is made by softer material and comprised the scraping edge.The whole bag of tricks that designs this hybrid element or hydrid component describes in detail in disclosed specification DE 198 56622 A1 and in No. the 101 15 311.2, the German patent application, at this with particular reference to these files.
The some of them hydrid component is equipped on the front and back of end wall, and is designed to the parts that commutate.By these commutation parts, material to be mixed transmits vertically away from each relevant end face.They are designed to L shaped and all have the scraping edge of a cylindrical sides that is equipped on the mixing channel inner surface and the scraping edge of each end face that is equipped on the mixing channel inner surface.
A kind of double-shaft mixer of the above-mentioned type for example, is disclosed by DE 198 56 622 A1.In the disclosure text, explained a kind of double-shaft mixer, the parts that wherein commutate comprise two radially adjacent one another are and be connected the hybrid element that mixes on the arm by this way, make its boundary face always adjacent one another are be substantially perpendicular to its scraping marginal portion separately in the end of mixing channel.Along radius inner be bearing in by corresponding retaining element along radius hybrid element externally with mix the mixing arm that axle links to each other on.In mixer operating period, the material to be mixed that is moved in mixing chamber by hybrid element is sent to power on the hybrid element of commutation parts, and this power is vertically away from the end face of mixing channel.Because the speed of mixing the arm motion along with from mix wheelbase from increasing and increase, and because material to be mixed also preferably is distributed in the mixing chamber of mixing channel side, be applied to the commutation blade along the mean value of power on the radius hybrid element externally in this case greater than being applied to along the mean value of radius corresponding force on the hybrid element of inside.For this reason, according to prior art, be necessary the external mix element is fixed in corresponding meticulousr mode in mixer and mix on the arm, so that avoid along the moving of radius hybrid element externally, this moves the increase of the distance at the scraping edge that causes from end face to the end face side.
In addition, under the situation of the commutation parts described in DE 198 56 622 A1, have a problem to be, the material to be mixed in the mixing axle zone of mixing channel end face be pressed in basically by moving of commutation parts leaning against of the mixing arm that mixes on the axle mix the FX on the axle and be fixed on the mixing arm along radius between the inner edge interface of the hybrid element of inside (radially).Material to be mixed building up in this zone causes a kind of situation, and material wherein to be mixed infiltrates in this zone and blocks bearing thus gradually, mixes axle and is installed in rotatably on the end wall of mixing channel by this bearing.In addition, material to be mixed also can infiltrate along radius between the hybrid element and mixing arm of inside, and promotes wearing and tearing thus until reaching a bit, separates along the hybrid element of radius in inside at that point.
Summary of the invention
The objective of the invention is thus,, and determine a kind of mixer, particularly double-shaft mixer or a kind of commutation parts with endurance and improved practicality of enhancing by further improvement prior art known mixer or known commutation parts.
In the mixer of the described type of beginning, this purpose reaches like this, if relevant the moving of married operation takes place, wherein become big along scraping marginal portion and the distance between the mixing channel end face that the end face of mixing channel extends, be bearing in along radius on the hybrid element of inside in just sealed mode along radius hybrid element externally at it.
Locomotivity is applied on the hybrid element by material to be mixed, and this locomotivity-be not fixed on mixes hybrid element on the arm-will be along moving hybrid element away from the bearing-surface on the mixing arm of mixing channel end wall.Therefore locomotivity mainly has a component in the axial direction.
The present invention has considered the following fact, owing to mix the speed and the distribution of material to be mixed in mixing channel of arm, the locomotivity that material to be mixed hybrid element is fixed on mixed on the arm is along with increasing from the radial distance that mixes axle and strengthening, and wherein this speed is along with strengthening from the increase of the radial distance that mixes axle.According to the present invention, what commutate parts along radius in effect inner and that reach along radius circuit elements design externally is, locomotivity is not only mixing on the arm by fixing along radius hybrid element externally, and via be fixed in by it mix on the arm be absorbed along the just sealed of hybrid element of radius in inside, this locomotivity is applied to along on the radius hybrid element externally by material to be mixed degree with an increasing, and it has caused along the preferred mobile trend of radius hybrid element externally away from end wall.
Preferably only hindering moving along radius in inside with along the just sealed connection between the radius hybrid element externally away from end wall.Yet a kind of so just sealed connection also is conceivable, has wherein prevented to move with respect to any of public bearing-surface that is mixing on the arm along them along the hybrid element of radius in inside along radius hybrid element externally.This can realize like this, for example, by along radius inner and along chimeric protuberance or recess mutually on the adjacent boundary face of radius hybrid element externally, perhaps also can connect or spline between the latter connects by zigzag.
Advantageously, if lean against along on the hybrid element of radius in inside along the hybrid element of radius in inside with flushing, so that obtain the smooth scraping edge of hydrid component, and in addition, also obtain the flat front of commutation parts on the boundary line of hybrid element ideally.Like this, can design the front of hydrid component by this way, make it have a foliaceous shape that all is used to transmit material to be mixed.In this connected, according to operating in the commutation parts during the rotation that mixes axle, the front of commutation parts will refer to the side that refers to forward.
Along radius the hybrid element of inside and along radius hybrid element externally preferably by in the front of hybrid element and/or the straight border edge on the back side lean each other.In this case, the front of hybrid element relates to the surface of hybrid element sensing front when hydrid component rotates, and the side of hydrid component is meant the surface of hybrid element point backward when hydrid component rotates.From the viewpoint of producing, the boundary edge that this linearity is extended is to realize easily.Alternatively, crooked boundary edge, for example Ao Ru boundary edge, promptly arch upward towards mixing axle, or the raised border edge, promptly deviate from and mix axle and arch upward, along radius at the hybrid element of inside with between radius hybrid element externally, also be fine.Yet, under boundary edge linearity and the simplest situation that extends parallel to each other,, realize at the boundary edge of the hybrid element of inside along having equably in the supporting on the front and back of hybrid element and there be not supporting on the adjacent edge interface of hybrid element of recess or protuberance along radius hybrid element externally along radius; And therefore identical supporting force is integrally applied, under the situation of the boundary edge of bending, perhaps under the situation at the uneven straight border edge on the front or the back side, along radius externally hybrid element and along the supporting between the hybrid element of radius in inside more on the side at scraping edge or more with relative side, scraping edge on, and/or realizing on the back side on the front of hybrid element or more more.In those had realized the zone of bigger supporting, hybrid element can be designed as firm especially thus.
Another selectable scheme to this is, along radius externally hybrid element and along the stair-stepping boundary edge between the hybrid element of radius in inside.In this case, realize supporting in the zone that those boundary edges radially extend basically basically.In these zones, for example hybrid element can be strengthened especially.On the other hand, be arranged essentially parallel in the zone of mixer axis extension at these boundary edges, in fact supporting takes place, and this permission hybrid element in these zones is made with softer material.
In addition, according to preferably design by this way of commutation parts of the present invention, make the scraping edge and along the hybrid element of radius in inside lean against along between that boundary edge on the radius hybrid element externally along the angle that forms on the front of radius in inside, and/or towards the edge of end face and along the hybrid element of radius in inside lean against along between that boundary edge on the radius hybrid element externally in the angle that on the quilt cover of the hybrid element of inside, forms along radius, all greater than 90 °.For along radius externally with along the situation at the straight border edge between the hybrid element of radius in inside, during moving away from end face, reaching by this condition along the just sealed supporting on the hybrid element of radius in inside along radius hybrid element externally along radius hybrid element externally.
Along radius the hybrid element of inside lean against along that boundary face on the radius hybrid element externally with along the leaning against of radius hybrid element externally along that the corresponding boundary face on the hybrid element of radius in inside, can be flat under the simplest situation.In addition, however boundary face stair-stepping, arch or spill also is conceivable.Stair-stepping boundary face also can design by this way, make and only during moving, be supported in along on the radius hybrid element externally away from end face along radius hybrid element externally, for example, the ladder that extends in parallel by boundary edge with front and back.
If overlap each other along the leaning against of hybrid element of radius, particularly can reach along radius hybrid element externally and effectively support along that boundary face on the radius hybrid element externally with along leaning against of radius hybrid element externally along that right on the hybrid element of radius in inside boundary face in inside.In this case, on the one hand, and guaranteed the danger that does not deviate from end wall and move along radius hybrid element externally towards end wall along just sealed connection of radius at the hybrid element of inside.In addition, boundary face also can be on a bearing of trend that is substantially perpendicular to the hybrid element front and back interlocked with one another or overlap joint.In this case, the interlocking of two boundary faces that lean each other or overlapping having impelled, two are connected to the hybrid elements that mix on the arm and guarantee by just sealed connection, one with mix the arm quadrature and corresponding hybrid element attempt not move along the direction that it separates from mix arm.Certainly, also can imagine,, guarantee that corresponding another hybrid element is by corresponding overlapping this moving that do not have of its boundary face under every kind of situation only for one in two hybrid elements.For example, preferably stipulate according to the present invention, along radius leaning against at the hybrid element of inside along that boundary face on the radius hybrid element externally, as watching, at least in part in the extension below that boundary face on the hybrid element of radius in inside that leans against along radius hybrid element externally from the front of hybrid element.In this case, because the bigger peripheral speed and the average weight than big bear of material to be mixed, the fact of use is to be pressed in the big degree of the hybrid element of inside along radius with an average specific along radius hybrid element externally and to mix on the arm.The boundary face design that is provided with according to the present invention thus, the particle that has prevented material to be mixed is pressed in the zone of boundary face, and prevented to enter by this way between one of them hybrid element and the mixing arm, and prevented the particularly factor of each hybrid element acceleration separation that increases that to cause wearing and tearing.
Another improvement according to mixer of the present invention, can reach by in mixing the axle zone, being connected another sealing hybrid element that mixes on the arm, the sealing hybrid element has a scraping edge that extends along the end arm, it-when projection radially-mixing axis and along radius between the boundary face of radius, extending at least at the hybrid element of inside in inside, on the direction of rotation of commutation parts, the commutation parts that this scraping edge works at the end face to mixing channel by along radius inner and move along the front at the scraping edge that radius hybrid element externally forms.The use of sealing hybrid element has been guaranteed, adheres to the material to be mixed on the end wall, around mixing on the front of the hybrid element of the hydrid component that is directed into rotation fully.Be positioned at the particle of the material to be mixed in the zone of mixing axle on the respective end walls, can prevent from by the rotation of hydrid component to be sent to along radius in radially the boundary face and the zone between the mixing axle of the hybrid element of inside, and can prevent to gather there in inside.This particle that will cause material to be mixed that gathers can infiltrate in the bearing, mix axle and be installed on the end wall of mixing channel by this bearing, and these particles can penetrate into mix arm and along radius between the hybrid element of inside.First kind of situation causes and will mix damage of bearings aspect the axle rotatory, and gets clogged under opposite extreme situations.Latter event will cause little by little unclamping from mixing arm along the hybrid element of radius in inside, and therefore cause the wearing and tearing of hybrid element to increase.Be pointed out that the sealing hybrid element has improved the commutation parts, even commutation blade otherwise be conventional design.
According to the present invention's regulation, the commutation parts preferably are used on the double-shaft mixer, and wherein the mixer of two described types is provided with by this way, and their mixing chamber is merged each other, and is provided with by this way, makes two mixer axis parallel to each other basically.

Fig. 3 shows from another perspective view according to commutation parts of the present invention by Fig. 2 that direction is seen shown in the arrow I Fig. 2.
The specific embodiment
The mixing channel of double-shaft mixer is represented with 10 in Fig. 1.Two mixing axles 14 are installed on the end wall 12 of mixing channel 10, have described one of them and have mixed the axis A-A of axle.Mixing axle 14 is driven by the motor (not shown) on the direction of rotation of rotation arrow 16.Hydrid component or blade 18 and 20 are arranged on and mix on the axle 14.Blade 18 is designed to the axial feed blade, and it on the direction of arrow 22 is being applied to axially-movable on the material to be mixed.Blade 20 is designed to conventional commutation blade, and it transmits material to be mixed on the direction of arrow 24 along the direction transverse to axis A-A, mixes axle 14 zones from one in all cases and mixes the zone of axle 14 to another.
Mixing channel 10 usefulness glass ceramics lining tile linings, the glass ceramics lining tile forms groove inner surface 26. Blade 18 and 20 is arranged to make its outward flange 28 to be positioned at closely locating from mixing channel inner surface 26.The outward flange 28 and the surface line M of blade 18 intersect established angle α.
Illustrate with the perspective view that amplifies in Fig. 2 according to commutation blade 20 of the present invention, commutation blade 20 can be with being made in the hybrid blade that is used in the end face side of the double-shaft mixer shown in Fig. 1 10.Commutation blade 20 has a scraping edge 32,34, it and the end face 12 and the side 26 adjacent (all not shown in Fig. 2) that are equipped on commutation blade 20.Commutation blade 20 has a front 38 and a back 40.Here, " front " is meant this side of commutation blade 20, promptly around mixer axis A-A that side of rotating forward of direction of rotation along commutation blade 20.The back 40 of commutation blade 20 correspondingly refers to the relative side of rotation backward.
Two hybrid elements 44,46 are fixed on by elongated poroid opening 70 and screw 72 and mix on the arm 42, so that they rotate around the mixer axis A-A with above-mentioned mixing arm 42, in addition, hybrid element 44,46 is arranged in such a way, and makes scraping marginal portion 50, the 48a of their adjacent end wall 12 separately form the scraping edge 32 of the straight line of an adjacent end wall 12 common, commutation blade 20.
In the confined state of commutation blade 20, hybrid element 44,46 is fixed on and mixes on the arm 42, and the boundary face of hybrid element 44,46 leans each other.As can see from Figure 2, radially externally hybrid element 44 and radially the hybrid element 46 in inside the boundary face 52 with straight line leans each other in its front.Also as can be seen, be formed on along radius on the front 62 of the hybrid element 46 of inside, radially at the scraping edge 50 of the hybrid element of inside with lean against radially angle beta between the boundary face 52 on externally the hybrid element 44 greater than 90 °.The geometry of these two hybrid elements 44,46 guarantees, if the displacement relevant with married operation takes place, during this period, distance attempt between the end face 12 of its scraping fringe region 48a that extends along mixing channel end face 12 and mixing channel becomes big, and radially hybrid element 44 externally is supported on radially on the hybrid element 46 of inside in the mode of just sealed (positive locking).
Fig. 3 shows another perspective view of the mixer commutation parts 20 of the Fig. 2 that sees with direction shown in the arrow I from Fig. 2.The element shown in Fig. 3 with have identical Reference numeral in the respective element shown in Fig. 2.For the explanation of their functions, please refer to explanation to Fig. 2.
As can be seen from Figure 3, hybrid element 44,46 is fixing by screw 72 and nut 7, and screw passes the elongated hole 70 shown in Fig. 2.For the detailed description that hybrid element 44,46 is fixed on other method of mixing arm 42, can be with reference to No. the 101 15 311.2, applicant's German patent application.
In Fig. 3 also as can be seen, as watching, lean against radially and radially to extend to leaning against under that boundary face on the hybrid element 46 radially of externally hybrid element 44 on the hybrid element 44 externally in inside in the boundary face of the hybrid element 46 of inside from the front of hybrid element 46,44.As watching, obtained the boundary face that leans each other stepped of two hybrid elements 44,46 thus from the position as shown in Fig. 3.This layout guaranteed, along radius at the hybrid element 46 of inside by being fixed with respect to displacement in just sealed mode away from the bearing-surface that is mixing the hybrid element 46 on the arm 42 along radius hybrid element 44 externally.Because the operating period of mixer acts on radially the power on externally the hybrid element 46 and hybrid element 44 is shifted onto power on the bearing-surface of mixing arm 42, on mean value, greater than acting on along the power on the hybrid element of radius in inside in mixer operating period, this arranges assurance, and two hybrid elements 44,46 are pushed safely each other in the boundary face zone that they lean each other.In mixer operating period, this special possibility of getting rid of is, the particle of material to be mixed can be pressed between two hybrid elements 44,46, and also can little by little be pushed to hybrid element 44,46 and between the bearing-surface that mixes on the arm 42, and get rid of a factor that will cause accelerated wear test to separate with hybrid element 44,46.
Especially can see that from Fig. 2 an other sealing hybrid element 80 is connected to and mixes on the arm 42 (not shown in Fig. 2) in mixing axle 14 zones.Sealing hybrid element 80 has a scraping edge 82, this scraping edge 82 extends along the end wall 12 of mixing channel, and-in the radially projecting-greatly about the mixer axis A-A with radially in radially between the boundary face in inside of hybrid element 46 of inside.Simultaneously, the scraping edge of sealing hybrid element 80 is arranged like this, on the direction of rotation 16 of commutation blade 20, it surpasses the scraping edge 32 of commutation blade 20 with the end wall 12 of mixing channel, it by along radius inner and form along radius hybrid element 46,44 externally.The function of sealing hybrid element 80 mainly is, prevent material to be mixed motion by commutation blade 20 be pressed into mix axle 14 and along radius the hybrid element 46 of inside along between the boundary face of radius in inside, the gathering in end wall 12 is in the zone of mixing axle 14 of this material to be mixed.Material to be mixed gathering in this zone will cause a kind of material to be mixed to infiltrate and little by little stop up the situation of swivel bearing, mixing axle 14 in this way is installed on the end wall 12 of mixing channel, and material wherein to be mixed infiltrate to mix between arm 42 and the hybrid element 46, and causes the factor of wearing and tearing and separating with hybrid element 46.
The detailed description of the invention a kind of mixer, the wearing and tearing that wherein mix the wearing and tearing of axle or its bearing and be equipped on the commutation blade on the mixing channel end face can be lowered due to the fact that, promptly, can prevent material to be mixed in mixer operating period and end wall adhesion, penetrate between the mixing arm of hybrid element and commutation parts, perhaps can prevent the gathering between parts and the mixing axle of commutating.
