Description

The invention relates to devices for mixing, in particular continuous operation for mixing components of coarse, juicy, watery and concentrated feeds.

Known drum feed mixer, and.with. No. 1666173, cl. B01F 19/02, 1987, comprising a drum, with helical surfaces consisting of sections, each of which is made of identical plates, having the shape of equilateral triangles, interconnected by two sides on the surface of the drum and placed at an angle to each other and to its axis, while the sections are interconnected by the free sides of the plates and form multidirectional screw surfaces of equal pitch, and the number of plates in the section is even and at least six.

The disadvantages of the known device are limited technological capabilities and the need to create a tilt of the drum for transporting feed components from loading to unloading.

Closest to the proposed invention is a patent. A23N 17/00, 1995, containing a bed, a drum mounted on it with the possibility of rotation, consisting of sections made in the form of a straight triangular prism formed by the cross section of the cube diagonally, moreover, the same edges of adjacent sections are connected at right angles.

The disadvantages of the known device are limited technological capabilities and the need to create a tilt of the drum for transporting feed components from loading to unloading.

The technical solution to the problem is to expand technological capabilities and ensure the transportation of feed components from loading to unloading with a horizontal axis of rotation of the drum, increasing productivity.

The technical solution is achieved by the fact that in a feed preparation machine containing a drum, loading and unloading devices, the drum is rigidly mounted on a platform with a vibrator mounted horizontally below the platform, and is made spiral from a hollow perforated tunnel with a multi-helical perforated surface around the perimeter rolled up in a spiral axis O ₁ -O ₁ around the central rectilinear axis O ₂ -O ₂ spiral filter provided with helical grooves inside at an angle to its spiral axis in the form of pockets of curvilinear shape with centers of curvature located inside the cross section of a hollow perforated tunnel, and assembled from sections in the form of identical perforated rings of the same shape and size, rolled up from the same perforated diamond-shaped strips on which trapeziums are located, the sides of which are located on the side rhomboid sides perforated strip and the upper and lower bases of the trapezoid are arranged at an acute angle to the symmetry axis of the perforated strip rhomboid O ₃ -O ₃ and is Xia fold lines which are at a distance from each other equal to the length of the pockets of the curved shape along the inner surface of the perforated perforated hollow tunnel spiral filter, while sections in the form of rings interconnected sides of trapezoids.

According to the patent literature not found a technical solution similar to the claimed, which allows to judge the inventive step of the machine for preparing feed.

The novelty is due to the fact that the drum is made spiral with a multiple helical surface, which increases the intensity of the interaction of the feed components and expands the technological capabilities.

The novelty is that the installation of a vibrator under the base with the drum provides a vibration path of the drum along with the feed components in the form of a vertical ellipse, which increases the specific gravity of the total kinetic energy (E _n ) and increases productivity.

The novelty is that the spiral drum with a multiple helical surface along the perimeter is equipped with screw grooves inside and outside at an angle to the spiral axis of symmetry O ₁ -O ₁ hollow tunnel of a spiral shape with a central rectilinear axis O ₂ -O ₂ , which increases the productivity of feed preparation and expands technological capabilities.

The novelty lies in the fact that the spiral grooves of the spiral drum are made in the form of pockets of a curved shape located inside the cross section of the hollow tunnel, which expands technological capabilities and increases the productivity of feed preparation.

The novelty is seen in the fact that the spiral drum is assembled from the section in the form of rings of the same shape and size, rolled up from the same diamond-shaped stripes, on which trapeziums are located on the sides of the diamond-shaped strip, and the upper and lower bases of the trapezoid are at an acute angle to the axis of symmetry diamond-shaped stripes O ₃ -O ₃ and are fold lines located at distances from each other equal to the length of the pockets of a curvilinear shape along the inner surface of the hollow tunnel of the spiral drum, with the sections in the form e rings are connected to each other by the lateral sides of the trapezoid, this increases the productivity of cooking feed.

The novelty of the proposal also lies in the fact that along the entire perimeter of the spiral drum, the passage section varies not only in shape but also in area, which provides alternate compression and expansion of feed component flows in each section of the spiral drum, increases productivity and expands technological capabilities.

The novelty of the invention lies in the fact that the trapezoid of the diamond-shaped strips from which the sections are mounted are not only inclined to each other, but also to the axis of symmetry of the spiral drum, so the compression ratio of the particles of the feed components increases and the process of preparing the feed is intensified.

The novelty lies in the fact that the drum is made of sections, the walls of which are inclined not only to each other, but also to the direction of the rotational movement of the flows of particles of the feed components moving under the influence of vibration in planes perpendicular to the passage section of the drum, this complicates the trajectory of their movement and increases the intensity of feed preparation and enhances technological capabilities.

The feed preparation machine (Fig. 1) contains a drum 1, rigidly fixed to the platform 2 elastically with four rubber-cord cylinders 3 mounted on the base 4. A device 5 is rigidly fixed to the platform 2, and a vibrator 6 c is also rigidly attached from below to the platform 2 horizontal axis of rotation. The feed preparation machine is equipped with an unloading device 7 for receiving finished feed.

The vibrator 6 is mounted horizontally under the platform 2 and therefore provides the movement of particles of bulk materials inside the drum 1 under the influence of the vibrator 6 along elliptical trajectories. The drum 1 (Fig. 1, Fig. 2, Fig. 3) is made spiral. In FIG. 4 shows a visual representation of the relative position of the axis of the spiral - the center of the axis of symmetry O ₁ -O _{1 of the} hollow tunnel, spiral drum 1 (in Fig. 4, the spiral drum is shown in cross sections 13 of the hollow tunnel with a multi-helical surface) and the central straight axis O ₂ -O ₂ spiral drum 1.

Thus, around the perimeter, the spiral drum 1 is made in the form of a spiral-shaped tunnel with a multiple helical surface around the perimeter and is equipped with screw grooves inside and outside, located at an angle α to the axis of symmetry of the spiral O ₁ -O _{1 of the} center of the axis of symmetry (Fig. 3) of the tunnel spiral, coiled O ₁ -O ₁ around the central axis of O ₂ -O ₂ spiral drum 1.

The helical grooves of the spiral drum 1 are made in the form of pockets 14, 15, 16, 17, 18, 19 on the inner surface and pockets on the outer surface 20, 21, 22, 23, 24, 25 of the spiral-shaped tunnel (Fig. 4) in the form of pockets curved shape with centers of curvature located inside the cross-section of the hollow tunnel, the drum is assembled from sections in the form of rings 26 of the same shape and size, connected to each other by the sides 27 and 28 (Fig. 7).

The result is a hollow tunnel of the spiral drum 1 (Fig. 1, Fig. 2, Fig. 3) with the axis of the spiral — the center of the axis of symmetry O ₁ -O _{1 of the} spiral filter 1, twisted around the central straight axis O ₂ -O _{2 of the} spiral drum 1 diameter D _cp with the formation of a spiral drum 1 with an outer diameter of D _max and an inner diameter of D _min (Fig. 4).

In this case, the hollow spiral drum 1 with a multiple helical surface is provided with helical grooves in the form of pockets 14, 15, 16, 17, 18, 19 and pockets 20, 21, 22, 23, 24, 25 along the outer surface of the spiral drum 1 (Fig. 4 )

Thus, a hollow tunnel with its own spiral axis of symmetry О ₁ -О _{1 is} rolled along this spiral О ₁ -О ₁ around the central rectilinear axis О ₂ -О ₂ and form a spiral drum 1 (Fig. 4).

Section 26 is made in the form of a ring (Fig. 7) and is mounted from a diamond-shaped perforated strip 29.

A trapezoid 30, 31, 32, 33, 34, 35 is placed on the diamond-shaped strip 29, the sides of which are located on the sides of the diamond-shaped strip 29, and the upper and lower bases of these trapezoids (Fig. 5) are located at an acute angle β to the axis of symmetry of the diamond-shaped stripes O ₃ -O ₃ and are bend lines (Fig. 5, Fig. 6) located at distances from each other equal to the length of the scan of the perimeter of the curved pockets (Fig. 7) of the spiral drum 1, made in the form of a hollow perforated tunnel.

In FIG. 5 shows the trapezoid:

- первая трапеция;

- first trapezoid;

- вторая трапеция;

- second trapezoid;

- третья трапеция.

- the third trapezoid.

является наименование из всех верхних оснований трапеций, расположенных на ромбовидной полосе 29 ниже линии сгиба

и вышеперечисленных трех трапеций (первой, второй, третий).Wherein

is the name of all the upper bases of the trapezoid located on the diamond-shaped strip 29 below the fold line

and the above three trapezoid (first, second, third).

In FIG. 5 also shows the trapezoid:

- четвертая трапеция;

- the fourth trapezoid;

- пятая трапеция;

- fifth trapezoid;

- шестая трапеция.

- the sixth trapezoid.

является наименьшим основанием из всех верхних оснований трапеций, расположенных на ромбовидной полосе 29 выше линии сгиба

которая для всех трапеций, в свою очередь, является наибольшей из всех нижних оснований с четвертой трапеции по шестую трапецию.Wherein

is the smallest base of all the upper bases of the trapezoid located on the diamond-shaped strip 29 above the fold line

which for all trapezes, in turn, is the largest of all lower bases from the fourth trapezoid to the sixth trapezoid.

является не только нижним основанием трапеции

но и одновременно самым длинным основанием трапеции

и самой длинной из всех нижних линий сгиба ромбовидной полосы 29 и кольца 26 (фиг. 7).Thus the fold line

is not only the bottom of the trapezoid

but also at the same time the longest trapezoid base

and the longest of all the lower fold lines of the diamond-shaped strip 29 and ring 26 (Fig. 7).

и

являются самым коротким из всех линий сгиба ромбовидной полосы 29 и кольца 26 и

In this case, the fold lines

and

are the shortest of all the fold lines of the diamond-shaped strip 29 and the ring 26 and

и

определяет величину шага S₁ спирали О₁-О₁ а значит, и шаг навивки пустотелого тоннеля вокруг прямолинейной оси О₂-О₂ спирального барабана 1.Fold Line Length Ratio

and

determines the magnitude of the step S _{1 of the} spiral O ₁ -O ₁ and hence the step of winding the hollow tunnel around the rectilinear axis O ₂ -O _{2 of the} spiral drum 1.

For example, in FIG. 5 fold lines L ₆ <L ₅ <L ₄ <L ₃ and L ₀ <L ₁ <L ₂ <L ₃ . The diamond-shaped strip 29 is bent along the straight bend lines, which are the base of all six trapezoids and are parallel to each other (Fig. 5).

Then the diamond-shaped strip 29 is bent along the fold lines with the formation of semicircles 36 (Fig. 6) and then rolled up into a ring (Fig. 7) with pockets of curved shape 14, 15, 16, 17, 18, 19 with centers of curvature located inside the cross section rings 26.

Sections in the form of identical rings 26 are then connected to each other sequentially by the lateral sides 27 and 28 so that all fold lines are a continuation of the fold lines of the same ring of the previous ring.

As a result of such an assembly, helical lines are shown along the perimeter of the hollow spiral drum 1, shown in FIG. 3, for example, with thickened lines 37-38, 39-40.

Thus, the spiral drum 1 (Fig. 1, Fig. 2, Fig. 3) is made around the perimeter in the form of a multiple helical spiral surface with helical lines around the perimeter of the spiral filter 1 (two of the helical lines shown in Fig. 3 with thickened lines 37, 38, 39, 40) and screw grooves inside and outside of the spiral drum 1 in the form of pockets of curved shape 14, 15, 16, 17, 18, 19 on the inner surface and helical grooves on the outer surface 21, 22, 23, 24, 25, 26 at an angle α to the spiral axis of the hollow tunnel of the spiral shape of the spiral drum 1.

The feed preparation machine operates as follows.

The disturbing force of the vibrator 6 through the walls of the platform 2 and the drum 1 is transmitted to the particles of the feed components inside the drum 1 and entering the drum 1 in a continuous stream through the loading device 5. The particles of the feed components rotate along vertical elliptical trajectories, during which the feed preparation process occurs . In this case, the particles of the feed components not only intensively interact with each other, but also under the influence of vibration rotate in a plane perpendicular to the bore of the drum 1. Since the length of the drum 1 has a cross-sectional shape, shape and location, the disturbance of particle movement is aggravated feed components, which in this case, interacting with the walls of the drum, move from loading to unloading. The presence of helical surfaces and helical lines around the perimeter of the drum 1 contributes not only to the complication of the trajectories of the particles of feed components, but also to the movement along the passage section of the drum 1 towards the discharge side. In this case, the finished feed enters the tank 7.

When particles of feed components move along the feed section of the drum 1 due to a change in the feed size in shape and size, compression and rarefaction zones are formed in each section of the drum 1 throughout its volume, which also intensifies the process of preparing feeds and expands technological capabilities. Finished feed through the discharge window 36 is displayed in the tank 7.

Technical appraisal and economic advantages of the feed preparation machine arise due to the design of the drum in the form of a spiral, which provides reduction in overall dimensions, expansion of technological capabilities, increase in productivity and path (length) of movement of particles of feed components in the drum, the surface of which is equipped with unidirectional helical lines and helical surfaces in the form of pockets of curved shape.

Technical and economic advantages also arise due to the shape of the trajectory of the feed components in the form of a vertical ellipse, which provides an increase in the specific gravity of the total kinetic energy (E _p ) 1.3.-1.5 times and increases productivity by mounting the vibrator horizontally under the platform with the drum, which increases performance and expand technological capabilities.
