Detailed description of the invention
Below in conjunction with the elaboration that Fig. 2 ~ Fig. 6 carries out specifically to technical scheme provided by the invention, arbitrary technological means provided by the invention is carried out replace or all should within protection scope of the present invention by the technical scheme that two or more technological means or technical characteristic carry out mutually combining and obtain provided by the invention arbitrarily.
See Fig. 2, Fig. 3, Fig. 5 a-Fig. 5 d, the embodiment of the present invention provides a kind of stirring structure, and it comprises shaft 1 and mixing arm 2.Mixing arm 2 comprises blade body 21 and axle sleeve 22, and both are fixedly connected with.The endoporus of axle sleeve 22 is polygon, and the external surface shape of shaft 1 is mated with the internal via shape of axle sleeve 22; Axle sleeve 22 is set on shaft 1.
Technique scheme, uses mixing arm 2 to replace existing stirring vane, and makes the annexation between mixing arm 2 and shaft 1 be sheathed.Endoporus due to the axle sleeve 22 of mixing arm 2 is polygon, therefore axle sleeve 22 is set on shaft 1 mixing arm 2 just can be made to rotate along with the rotation of shaft 1.When wherein any one occurs wearing and tearing, damage for both mixing arm 2 and shaft 1, can keep in repair separately and change, therefore reduce maintenance and replacement cost.
Herein, further, an axle sleeve 22 only can arrange a blade body 21, separate between each mixing arm 2, when damaging appears in a mixing arm 2, that mixing arm 2 of damage also only can be changed separately.
Herein, blade body 21 and axle sleeve 22 can be formed in one, such as casting, and its material can select rich chromium cast iron.Rich chromium cast iron is wear-resisting, selects rich chromium cast iron can significantly improve the service life of mixing arm 2.
In order to improve stirring efficiency, blade body 21 is wedge structure, and shaft 1 exists the symmetrical shape of the blade body 21 on two axle sleeves 22.
In practical application, suitably can adjust position and the quantity of the blade body 21 of contrary working face according to mixing effect and discharging situation, such as be set to alternate layout etc.
See Fig. 5 a, Fig. 5 b, Fig. 5 c and Fig. 5 d, the wedge structure of blade body 21 is specific as follows herein: the local size that blade body 21 is connected with axle sleeve 22 is less, end size away from axle sleeve 22 is larger, from the direction of front view, blade body 21 is similar to right angled triangle, but right angle has rounding, hypotenuse is camber line.Wherein, the working face played a major role when the face at camber line place is and stirs, the setting direction of this working face is determined according to the rotation direction of shaft 1.That is, after the mixing direction of shaft 1 is determined, the setting direction of blade body 21 also just determines.
Comparison diagram 5a and Fig. 5 c, Fig. 5 b and Fig. 5 d, can see the symmetrical shape of the blade body 21 on two axle sleeves 22 adjacent in the present embodiment., be set to symmetry herein, effect is: the contrary working face in direction can block stream along shaft to the flowing of discharging opening, slows down axially-movable, and the convection current strengthening storeroom is impacted, and makes material stirring more abundant.
Fig. 5 a and Fig. 5 c is specular, such as, shaft 1 rotates to page inboard, and material moves from left to right along axle under the promotion of the blade body shown in Fig. 5 a, and the working face of the blade body shown in Fig. 5 c is contrary, be apply active force left, blocked the motion of material.
For improving the uniformity stirred, mixing arm 2 also comprises cylinder 23, and cylinder 23 wears blade body 21, and the length direction of cylinder 23 is parallel with the length direction of axle sleeve 22.
Cylinder 23, blade body 21 and axle sleeve 22 three can integrally casting shaping, the material of three all can adopt rich chromium cast iron.Hold above-mentioned, rich chromium cast iron is wear-resisting, selects rich chromium cast iron can significantly improve the service life of mixing arm 2.
Further, stirring structure also comprises spacer 3.Spacer 3 is also set on shaft 1, and is provided with spacer 3 between at least two adjacent axle sleeves 22, and spacer 3 is for regulating the spacing between axle sleeve 22.
The magnitude setting of mixing arm 2 is relevant with the material of material to be mixed, for a continuous mixer, the length of shaft 1 is determined, spacing between the quantity of mixing arm 2 and mixing arm 2 can be adjusted by spacer 3, needing the occasion arranging less mixing arm 2, several spacer 3 can be increased more.Otherwise, then can arrange less or spacer 3 be not set.
Spacer 3 is generally arranged between two mixing arms 2, and certainly, under some occasion, spacer 3 also can be arranged on the end of shaft 1.
While ensureing normal charging, stop the liquid material reflux of stirring area to feeding zone, the feed end of shaft 1 is provided with the first scraper 4.
In order to reduce the material after stirring to the shock of the dividing plate of continuous mixer discharge end, the discharge end of shaft 1 is provided with the second scraper 5.
The structure of the first scraper 4 and the second scraper 5 all with the similar of mixing arm 2, but setting direction is also contrary.
In the present embodiment, the endoporus of axle sleeve 22 can be quadrangle, pentagon or hexagon, and this sentences hexagon is example.Be set to above-mentioned shape and all can ensure that mixing arm 2 rotates along with the rotation of shaft 1.
Above-mentioned stirring structure is described in further detail below in conjunction with Fig. 5.Herein, in order to clear description.
As shown in Figure 5, stirring structure comprises shaft 1, first scraper 4, mixing arm 2, spacer 3, second scraper 5.The mixing arm 2 selecting rich chromium cast iron to make substitutes the stirring vane that original ordinary carbon steel is made, by the symmetric design of adjacent two mixing arm 2 blade bodies 21 and rationally arrange, the convection current that can strengthen storeroom while not affecting material axially-movable is impacted, make material stirring more fully, improve stirring efficiency.
Axle sleeve 22 endoporus of mixing arm 2 is hexagon, coordinates, do not need other connected modes with hexagonal shaft 1, and each mixing arm 2 can independent dismounting (see Fig. 6), and the spacing between adjacent mixing arm 2 regulates by spacer 3.Rich chromium cast iron select the service life that can significantly improve mixing arm 2, modularized design can realize the replacing of part or all of mixing arm 2, easy to maintenance and cost is lower.In addition, this mixing arm 2 can be used for the continuous mixer of different type spectrum, improves the versatility between product parts and interchangeability.
The embodiment of the present invention also provides a kind of continuous mixer, comprises the stirring structure that the arbitrary technical scheme of the present invention provides.
The continuous mixer that technique scheme provides, has above-mentioned stirring structure, solves the technical barriers such as existing stirring structure process is complicated, abrasion resistance properties is poor, service life is short.
In describing the invention; it will be appreciated that; term " orientation or the position relationship of the instruction such as " center ", " longitudinal direction ", " transverse direction ", "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", " outward " be based on orientation shown in the drawings or position relationship; be only for ease of describing the present invention and simplified characterization; instead of indicate or infer the device of indication or element must have specific orientation, be specific azimuth configuration and operation, thus can not be interpreted as restriction the present invention being protected to content.
