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.

A disadvantage of the known device is the 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 device for the preparation of feed Patent No. 2028070, class. 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.

A disadvantage of the known device is the 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 the device for preparing feed containing a drum, loading and unloading devices mounted on a bed, the drum is made spiral from a hollow tunnel with a multiple helical surface along the perimeter, rolled along a spiral axis 0 ₁ -0 ₁ around a central straight axis 0 ₂ -0 ₂ spiral drum provided with helical grooves inside and outside the spiral at an angle to the axis 0 _{1 1} -0 hollow tunnel in the form of pockets with three or more sides, and is assembled of sections minutes as identical in shape and size of rings rolled from strips of the same diamond shape, which has a trapezoid, the sides of which are located on the sides of the rhomboid strip, and the upper and lower bases of the trapezoids are arranged at an acute angle to the axis of symmetry of the strip ₃ -0 0 ₃ and are fold lines located at distances from each other equal to the lengths of the sides of the pockets, with the sections connected to each other by the lateral sides of the trapezoid.

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

The novelty is due to the fact that the drum is made spiral with a multiple helical surface, which increases productivity and expands 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 0 ₁ -0 ₁ hollow tunnel of a spiral shape with a central rectilinear axis 0 ₂ -0 ₂ , which increases the productivity of feed preparation and expands technological capabilities.

The novelty is that the spiral grooves of the spiral drum are made in the form of pockets with three or more sides located inside and outside the cross section of the hollow tunnel, which expands the 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 rhomboid strip ₃ -0 0 ₃ and fold lines are located at a distance from each other equal to the length of the sides of the pockets of the hollow tunnel spiral drum, the section in the form of rings are interconnected by side Vym the trapezoid, it improves the performance of the preparation of 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 the 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 differently inclined not only 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 differently inclined not only to each other, but also to the direction of the rotational movement of the particle flows 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 expands technological capabilities.

The invention is illustrated by drawings, where in FIG. 1 shows a device for the preparation of feed, General view; in FIG. 2 is a section Α-A in FIG. one; in FIG. 3 - a visual image of a spiral drum; in FIG. 4 - a visual representation of the relative position of the spiral 0 ₁ -0 ₁ , along which a hollow tunnel with a multiple helical surface is rolled around a central straight axis 0 ₂ -0 ₂ ; in FIG. 5 - one of the diamond-shaped strips on which trapezoids are placed, the upper and lower bases of which are located at an acute angle to the axis of symmetry of the strip 0 ₃ -0 ₃ in the form of fold lines; in FIG. 6 - a strip of rhomboid shape, bent along the fold lines - the upper and lower bases of the trapezoid; in FIG. 7 is a visual representation of a diamond-shaped strip rolled up into a ring when the upper base nn ′ of the trapezium mnn′m is connected to the lower base of the trapezoid ΝΜΜ′Ν ′.

The device for the preparation of feed (Fig. 1, Fig. 2) contains a drum 1, rigidly mounted on the platform 2, which is resiliently mounted using four rubber-cord cylinders 3 on the base 4. On the platform 2, the loading device 5 is rigidly fixed, and from the bottom to the platform 2 rigidly attached vibrator 6 with a horizontal axis of rotation.

Installation for the preparation of feed is equipped with a discharge device 7 for receiving finished feed.

The vibrator 6 is mounted horizontally under the platform 2 and therefore provides the movement of particles of the feed components 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 mutual arrangement of the axis of the spiral - the center of the axis of symmetry 0 ₁ -0 _{1 of the} hollow tunnel of the spiral drum 1 (in Fig. 4, the spiral drum is shown conditionally with a cross section 8 of the hollow tunnel with a multi-helical surface) and the central straight axis 0 ₂ -0 ₂ spiral drum 1.

Thus, around the perimeter, the spiral drum 1 is made in the form of a spiral-shaped tunnel with a multi-helical surface along the perimeter and is equipped with screw grooves inside and outside, arranged at an angle α to the axis of symmetry of the spiral 0 ₁ -0 _{1 of the} center of the axis of symmetry (Fig. 3) of the tunnel spiral, coiled 0 ₁ -0 ₁ around the central axis 0 ₂ -0 _{2 of the} spiral drum 1.

The helical grooves of the spiral drum 1 are made in the form of pockets 9, 10, 11, 12, 13, 14 along the inner surface and pockets along the outer surface 15, 16, 17, 18, 19, 20 of the spiral shape tunnel (Fig. 3 and Fig. 4 ) with three or more sides and mounted from sections in the form of identical rings 21 (Fig. 7), connected to each other by the sides 22 and 23.

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 0 ₁ -0 _{1 of the} spiral drum 1, twisted around the central straight axis 0 ₂ -0 _{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 with an inner diameter of D _min (Fig. 4).

In this case, the hollow spiral drum 1 with a multi-helical helical surface is provided with helical grooves in the form of pockets 9-14 on the inner surface and pockets 15-20 on the outer surface of the spiral case 1 (Fig. 4).

Thus, a hollow tunnel with its own spiral axis of symmetry 0 ₁ -0 _{1 is} folded along this spiral 0 ₁ -0 ₁ around the central rectilinear axis 0 ₂ -0 ₂ and forms a spiral drum 1 (Fig. 4).

Section 21 is made in the form of a ring (Fig. 7), mounted from a diamond-shaped strip 24 (Fig. 5), on which trapeziums are placed, the sides of which are located on the sides of the diamond-shaped strip 24, and the upper and lower bases of these trapezoids (Fig. 5 ) are disposed at an acute angle β to the axis of symmetry of diamond strip ₃ -0 0 and ₃ are the fold lines (FIG. 5 and FIG. 6) disposed at a distance from each other equal to the length of the sides of the pockets of the spiral drum 1 is formed in the shape of hollow spiral the tunnel.

In FIG. 5 shows the trapezoid:

ΝΜΜ′Ν ′ - the first trapeze,

MFF′M ′ - second trapezoid,

FEE′F ′ - the third trapezoid,

ΕΤΤ′E ′ - the fourth trapezoid,

TNN′T ′ - fifth trapezoid,

HRR′H ′ - sixth trapezoid,

RSS′R ′ is the seventh trapezoid,

SLL′S ′ - the eighth trapezoid,

LGG′L ′ - ninth trapeze,

GJJ′G ′ - the tenth trapezoid,

JZZ′J ′ - the eleventh trapezoid,

ZWW′Z ′ is the twelfth trapezoid.

Moreover, ΝΝ ′ is the smallest of all the upper bases of the trapezoid located on the diamond-shaped strip 24, below the bend line WW ′ ′, and WW ′ is the largest of all the lower bases of the trapezoid located on the diamond-shaped strip 24, below the bend line WW ′ and the above twelve trapezoid.

In FIG. 5 also shows the trapezoid:

WPP′W ′ - the thirteenth trapezoid,

Pjj′P ′ - the fourteenth trapezoid,

jgg′j ′ - the fifteenth trapezoid,

gkk′g ′ is the sixteenth trapezoid,

kss′k ′ - seventeenth trapezoid,

srr′s ′ - the eighteenth trapezoid,

rhh′r ′ - nineteenth trapezoid,

htt′h ′ is the twentieth trapezoid,

tee′t ′ - twenty-first trapeze,

eff′е ′ - twenty-second trapezoid,

fmm′f ′ - twenty-third trapezoid,

mnn′m ′ is the twenty-fourth trapezoid.

Moreover, nn ′ is the smallest base of all the upper bases of the trapezoid located on the diamond-shaped strip 24 above the fold line WW ′, which for all trapezoids, in turn, is the largest of all the lower bases from the thirteenth to the twenty-fourth trapezoid.

Thus, the fold line WW ′ is not only the lower base of the trapezoid ZWW′Z ′, but also the upper base of the trapezoid PWW′P ′ and the longest fold line of the ring 21 and the diamond-shaped strip 24.

Moreover, the fold lines ΝΝ ′ and nn ′ are the shortest of all the fold lines of the diamond-shaped strip 24 and ring 21.

The ratio of the length of the bend line WW ′ and NN ′ (nn ′) determines the value of step S, spiral 0 ₁ -0 ₁ , and therefore the pitch of winding the hollow tunnel around the straight axis 0 ₂ -0 _{2 of} spiral drum 1.

The diamond-shaped strip 24 is bent along the straight fold lines, which are the bases of twenty-four trapezoids, as shown in FIG. 6, parallel to each other, and then rolled into a ring 21 (vig. 7) with a multifaceted surface.

The edges nn ′ and ΝΝ ′ are joined by known methods, for example by welding, soldering, etc., with the formation of a section in the form of rings 21 (Fig. 7).

Sections in the form of identical rings 21 are connected to each other sequentially by the lateral sides 22 and 23 so that all the fold lines are a continuation of the fold lines of the same name of the previous ring.

As a result of such assembly, helical lines are formed along the perimeter of the hollow spiral tunnel, as shown in FIG. 3, for example, with a thickened line 25-26-27-28-29-30-31-32-33-34-35.

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 drum 1 (one of the helical lines shown in Fig. 3 with a thickened line 25- 26-27-28-29-30-31-32-33-34-35 and screw grooves inside and outside of the spiral drum 1 in the form of pockets of a polygonal shape 9, 10, 11, 12, 13, 14 on the inner surface and 15, 16, 17, 18, 19, 20 along the outer surface in the form of pockets of a polygonal shape at an angle α to the spiral axis of the hollow spiral tunnel with WASHING drum 1.

A spiral drum 1 (Fig. 1, Fig. 2, Fig. 3) in the form of a spiral hollow tunnel with a helical surface along its inner and outer perimeters with the formation of pockets of a polygonal shape can be made in another way.

A device for preparing feed is as follows.

The perturbing force of the vibrator through the walls of the spiral drum 1 is transmitted to the particles of the feed components inside the spiral drum 1 and entering the spiral drum 1 in a continuous flow 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 spiral drum 1. Since spiral drum 1 has a cross-sectional size, shape and location, the disturbance of movement is aggravated particles of feed components, which in this case interact with pockets of the polygonal shape of the inner walls of the spiral drum 1, i.e. there is an increase in the intensity of preparation of feed. The presence of helical surfaces and helical lines around the perimeter of the spiral drum 1 contributes not only to the complication of the trajectories of the particles of feed components, but also to their movement along the bore of the spiral drum 1 in the direction of unloading and unloading device 7.

When particles of the feed components move along the bore of the spiral drum 1 due to a change in the bore in shape and size, compression and rarefaction zones are formed in each section of the spiral drum 1 throughout its volume, which also intensifies the process of preparing the feed and expands technological capabilities.

Technical and economic advantages arise due to the fact that the spiral drum is made spiral from a hollow tunnel with a multiple helical surface along the perimeter, rolled up in a spiral, which provides increased productivity and expansion of technological capabilities, as well as due to the installation of a vibrator horizontally below the platform with a spiral drum, which provides an increase in the specific gravity of kinetic energy by 1.3-1.5 times and increases productivity.
