Description

The invention relates to devices for mixing, in particular to devices for continuous operation, and can be used for mixing 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 due to the fact that mixing is carried out with insufficient mixing intensity and insufficient interaction of the feed components with each other, as well as the need to create a tilt of the drum for transporting them from loading to unloading.

Closest to the proposed invention is a device for the preparation of feed - patent No. 2358620, class. A23N 17/00, publ. 06/20/2009, bull. No. 17, comprising a bed, a toroidal working chamber mounted on it with a drive, made of sections made of strips bent to one side in straight lines placed at an angle to the edges of the strips, with alternating formation of different sizes of equilateral and isosceles triangles, while on the two sides of the largest equilateral triangle, two identical isosceles triangles are located with their bases, on the sides of which are two identical equilateral t a triangle with two identical isosceles triangles located at its base, on one of which there is an equilateral triangle, the sides of the smaller equilateral triangles differ from the sides of the large equilateral triangles by the same linear value, and the sections are connected to each other by the free sides of the mentioned triangles with the formation on the outer and inner surfaces of the toroidal working chamber, directed towards each other broken lines and screws x surfaces located at an angle to each other.

A disadvantage of the known device is the limited technological capabilities due to the fact that mixing is carried out with insufficient mixing intensity and insufficient interaction of the feed components with each other over a relatively short length (around the circumference) of the working chamber in the form of a torus.

The technical solution to the problem is to expand technological capabilities, increase productivity and the path (length) of the movement of feed components in the working chamber.

The technical solution is achieved by the fact that in a vibrating installation for mixing bulk materials containing a working chamber elastically mounted on a base and equipped with a drive, the working chamber is hollow in the form of a square with a curved helical surface along the inner perimeter in the form of pockets of a multifaceted shape in the form of various geometric shapes with four or more lateral sides and is mounted from four hollow sections rigidly alternately rigidly connected to each other, made in the form of a hollow circular th sector with four hollow rectilinear sections, and four sections made in the form of a hollow circular sector made of a strip rolled into a ring with a multifaceted surface and the formation of different-sized quadrangles with two parallel sides parallel to each other with the formation of subsections, while subsections connected to each other by the free sides of the said quadrangles in the form of a hollow circular sector made with a multiple helical surface, equipped with helical grooves inside the circular sector at an angle to its axis in the form of pockets of polygonal shapes of various geometric shapes with four or more sides, the distance between the straight fold lines being equal to the length of each polygon element, and four hollow rectilinear sections are made of at least one strip bent in straight lines placed at an angle to the edges of the strip, with the formation of parallelograms located on the strip alternately in opposite directions, while folded into cylindrical turns connected to each other along longitudinal edges to form unidirectional broken helical lines on the outer surface, and polygonal broken helical pockets on the inner surface in the form of various geometric shapes with four or more lateral sides, which around the perimeter can be different not only in shape, but also in size, while the distances between the fold lines are equal to each other and equal to the sum of the lengths of the perimeters of the geometric figures of the pockets of the inner surfaces.

According to the patent literature not found a technical solution similar to the claimed, which allows to judge about the inventive step of the proposed vibration installation for mixing bulk materials.

The novelty lies in the fact that the working chamber is made hollow in the form of a square with a curved helical surface along the inner perimeter in the form of pockets of a multifaceted shape, which expands technological capabilities, with the same dimensions with the working chamber, made in the form of a torus, technological capabilities expand and the path (length) of movement of the feed components in the square working chamber increases, since the length along the perimeter of the torus (circle) of diameter D is L ₁ = πD, and the length along the perimeter of the square is L ₂ = 4D. (L ₂ > L ₁ ).

The novelty is also due to the fact that the working chamber is mounted from four sections rigidly alternately rigidly connected to each other, made in the form of a circular sector with four rectilinear sections, which expands technological capabilities, since with the same dimensions with the working chamber made in the form of a torus , increases the path (length) of the movement of the feed components in the square working chamber.

The novelty is seen in the fact that the pockets of the working chamber are made in the form of geometric shapes of a polygonal shape from at least one strip, which expands the technological capabilities.

The novelty also lies in the fact that the pockets around the perimeter of the working chamber can be different not only in shape but also in size, which expands technological capabilities.

The novelty is also due to the fact that the distances between the fold lines of the pockets of the inner surfaces are equal to each other and equal to the sum of the lengths of the perimeters of the geometric figures of the pockets of the inner surfaces, which expands the technological capabilities.

The novelty is due to the fact that the working chamber is made hollow in the form of a square with a curved helical surface along the inner perimeter in the form of pockets of a multifaceted shape in the form of various geometric shapes with four or more sides, which provides not only the intensification of the interaction of feed components, increased productivity, but also expansion of technological capabilities.

The novelty of the proposal lies in the fact that polygonal surfaces are formed on the inner surface of the working chamber, which along the perimeter can be different not only in shape but also in size, which provides a change in the direction of feed components, resulting in increased productivity and expanded technological capabilities.

The novelty is due to the fact that the sections from which the working chamber is assembled are mounted around the perimeter from strips with quadrangles marked on them of different sizes and sizes, therefore, the intensity and productivity of the preparation of feed increases, and technological capabilities expand.

The novelty of the proposal also lies in the fact that the cross-sectional area around the entire perimeter of the working chamber changes not only in shape, but also in area, which provides alternate compression and expansion of the feed components in each section of the working chamber, which means increased productivity and expanded technological capabilities.

The novelty of the invention lies in the fact that the quadrangles of the strips from which the sections are mounted are not only inclined to each other, but also to the axis of symmetry of the working chamber, therefore, the degree of compression of the feed components increases, the process of preparing the feed is intensified.

The novelty also lies in the fact that the working chamber is made of sections and subsections, the walls of which are not only inclined to each other, but also to the direction of the rotational movement of the feed components moving under the influence of vibration in planes perpendicular to the bore of the working chamber, which complicates their trajectory movement, increases the intensity of the preparation of feed and expands technological capabilities.

The novelty also lies in the fact that when the vibrator is installed horizontally (unlike the analogue - patent No. 2358620, class A23N 17/00, publ. 06/20/2009, bull. No. 17, in which the vibrator is installed vertically), feed components performing circulating motion inside the working chamber in planes perpendicular to the axis of symmetry of the working chamber, receive additional movement from the walls of the pockets of the polygonal shape of all eight sections inclined to each other, which expands the technological capabilities and increases the productivity of cooking fodder feed.

The vibrating installation for mixing bulk materials (figure 1) consists of a working chamber 1 mounted on a platform 2, equipped with a vibrator 3. Platform 2 by means of springs 4 is mounted on the base 5.

The working chamber 1 is made in the form of a square (Fig. 2) with a polygonal screw surface along the inner perimeter (Fig. 3) in the form of pockets of a polygonal shape and is mounted from four sections 6, 7, 8, 9, rigidly connected alternately to each other, made in in the form of a circular sector with four rectilinear sections 10, 11, 12, 13 (figure 2).

Sections 6, 7, 8, 9 (Fig. 4) with a polyhedral helical surface along their inner perimeter are made of subsections 14 (one of the subsections in Fig. 4 is marked by solid thickened lines), interconnected by known methods, for example, welding, gluing and etc., with the formation of helical lines on the outer and inner surfaces (in Fig. 4, one of the helical lines is shown by a thickened line 15-16-17-18-19-20-20-22-22-23) and polygonal helical surfaces in various geometric shapes with four or more sides, for example a rectangular nick, trapezoid, rhombus, etc., in the form (5) of the outer surface of the pockets 24, 25, 26, 27, 28, 29 and the inner surface of polygonal shape pockets 30, 31, 32, 33, 34, 35.

Each of the subsections 14 is made in the form of a circular sector (Fig. 4, Fig. 5) and is mounted from a strip 36 (Fig. 6, Fig. 7), on which rectangles are marked, along the diagonals of which there are fold lines passing through points 37, 38 , 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60 at distances from each other, equal to the length of the side of the geometric figure, for example, as in Fig.6, at a distance L ₁ , L ₂ , L ₃ . The fold lines of the strip 36 are shown in FIG. 6 with a thickened line. On the strip 36 are also marked the cutting lines 61 of the edges of the strip 36, shown in Fig.6 with a dashed line with two points. After marking along the edge-cutting line 61, the sections of the strip 36 (in FIG. 6 these sections of the strip 36 are shaded) are cut off and the strip 36 takes on the form shown in FIG. 7, in which the fold lines of the strip 36 are different in length L ₄ , L ₅ , L ₇ , L ₈ , L ₉ , L ₁₀ , L ₁₁ , L ₁₂ , L ₁₃ , L ₁₄ , L ₁₅ , L ₁₆ , L ₁₇ , L ₁₈ , L ₁₉ , L ₂₀ , L ₂₁ , L ₂₂ , L ₂₃ , L ₂₄ , L ₂₅ , L ₂₆ , L ₂₇ .

The strip 36 (Fig.7) after trimming the edges of the rectangles along the trim lines 61 is bent in straight lines - the fold lines 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, placed at an angle α to the edges of the strip 36 (Fig. 8) with the formation of different-sized quadrangles with two parallel sides - i.e. along the diagonals passing through the points 37-60 of the rectangles (Fig.6) parallel to each other, and then collapses into a ring 14 with a multifaceted surface, as shown in Fig.9. The transverse edges 62 and 63 of the strip 36 (Fig.6, Fig.7) after folding into a ring 14 are connected by known methods, for example by welding, soldering, etc., with the formation of a subsection 14 in the form of a circular sector - ring 14 (Fig.9 4).

Thus, sections 6, 7, 8, 9 (Fig. 4, Fig. 5) are made around the perimeter in the form of a multiple helical surface with helical lines that vary in diameter of the section in increments of the perimeter of the section (one of the helical lines is shown in FIG. 4 with a thickened line 15-16-17-18-19-20-21-22-22-23), and screw grooves inside and outside sections 6, 7, 8, 9 in the form of pockets of a polygonal shape, at an angle to the axis of sections 6, 7 , 8, 9.

Sections 6, 7, 8, 9 (Fig. 4, Fig. 5) with a screw surface along its inner and outer perimeter with the formation of pockets of a polygonal shape can be made in other ways.

Four hollow rectilinear sections 10, 11, 12, 13 (FIG. 10, FIG. 11) with polygonal pockets, for example section 10, are made of at least one strip 64 connected along the longitudinal edges 65 (shown in FIG. 10 dashed line) by known methods, for example by welding, with the formation of helical lines along the outer and inner surfaces (in Fig. 10, one of the helical lines is shown by a thickened line 66-67-68-69-70-71-72-73-74- 75-76-77) and screw surfaces (11) of a rectangular shape in the form of pockets of the outer surface 78, 79, 80, 81, 82, 8 and pockets of the inside the bottom surface 84, 85, 86, 87, 88, 89.

Strip 64 (FIG. 12, FIG. 13) is bent along straight lines 90 at equal angles α to the longitudinal edges 65 of strip 64 placed at distances equal to the length of the polygon elements of the pockets, for example for pocket 81 at distances L ₁ , L ₂ , L ₃ .

The strip 64 after bending along straight lines (Fig. 12, Fig. 13) is folded into cylindrical coils (Fig. 14), connected to each other along the longitudinal edges 65 by known methods, for example by welding, into hollow straight sections 10, 11, 12, 13.

Hollow rectilinear sections, for example, 10, 11, 12, 13 with pockets of a polygonal shape are rigidly connected alternately with hollow sections 6, 7, 8, 9 with pockets of a polygonal shape (figure 2) along lines II, II-II, III- III, IV-IV, VV, VI-VI, VII-VII, VIII-VIII with the formation of a continuous hollow working chamber 1 in the form of a square with pockets of a polygonal shape along its inner perimeter.

A vibrating installation for mixing bulk materials is as follows.

The perturbing force of the vibrator 3 is transmitted through the walls of the working chamber 1 to the particles of feed components located inside the working chamber 1. The particles of the components under the influence of vibration rotate in planes perpendicular to the axis of symmetry of the hollow working chamber 1 and pockets of a polygonal shape along its perimeter. The presence of curved multidirectional elements, including pockets with a polygonal shape along the inner perimeter of the working chamber 1, changes the direction of movement of the feed components, as a result of which the feed components not only acquire directional movement from loading to unloading, but also compression zones are formed along the entire length of the component path feed inside the working chamber 1, increases the productivity of the preparation of feed, expanding technological capabilities.

The particles of the feed components not only intensively interact with each other, mixing, but also under the influence of vibration rotate in a plane perpendicular to the bore of the working chamber 1. Since the dimensions of the cross section along the length of the working chamber 1 change, the shape and location are aggravated. particle movements of feed components, i.e. there is an increase in feed preparation productivity. The presence of helical surfaces and helical lines around the perimeter of the working chamber ensures the movement of feed components not only in hollow rectilinear sections of the working chamber 1, but also in hollow sections made in the form of a circular sector, which contributes not only to complicate the trajectories of their movement, but also to move them along the cross section of the working chamber 1 from loading to unloading. When the feed components move along the feed-through section of the working chamber 1 due to the change in the feed-through section in shape and size, compression and vacuum zones are alternately formed in each section of the feed chamber 1 over its entire volume, which also intensifies the process of preparing feeds and expands technological capabilities.

Technical and economic advantages arise due to the implementation of the working chamber of a vibrating installation for mixing bulk materials in the form of a square, the inner surface of which is equipped with unidirectional helical lines and helical surfaces in the form of pockets of a polygonal shape, and also due to the fact that particles of feed components under the influence of vibration make rotational movement in planes perpendicular to the axis of symmetry of the hollow working chamber and pockets of a polygonal shape along its perimeter, and also due to that when the feed components move along the feed chamber cross section due to the change in the feed cross section in shape and size, compression and vacuum zones are alternately formed in each cross section of the cooking chamber throughout its volume, which intensifies the feed preparation process and expands technological capabilities.
