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 (AS USSR No. 1666173, class B01F 19/02, 1987), containing a drum with helical surfaces, consisting of sections, each of which is made of identical in size plates having the shape of equilateral triangles connected between 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 like the minimum is six.

A disadvantage of the known device is the limited technological capabilities due to the fact that mixing is carried out with insufficient intensity and insufficient intensity of 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 (RF patent No. 2358620, class A23N 17/00, publ. 06/20/2009, bull. No. 17) containing a frame mounted on it with a drive working chamber toroidal shape 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 along the length of the strip of different-sized equilateral and isosceles triangles, while on both sides of the largest equilateral triangle is located the wives with their bases are two identical isosceles triangles, on the sides of which are two identical equilateral triangles with two identical isosceles triangles located to them with their bases, on one of which is an equilateral triangle, and the sides of the smaller equilateral triangles differ from the sides of large equilateral triangles by one and the same linear value, and the sections are connected to each other by the free sides of the mentioned triangles with the formation along the outer and inner surfaces of the toroidal working chamber, broken helical lines directed towards each other and helical 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 intensity and insufficient intensity of 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 the vibrating device for mixing bulk materials containing a working chamber resiliently mounted on the base and equipped with a drive, the working chamber is hollow with a wavy helical surface and is mounted from four circular sections and four rectilinear sections rigidly alternately connected to each other, while the circular sections are mounted from subsections, each of which is made of a strip bent in a wavy shape and rolled into a ring with the formation of different the sizes of the quadrangles with two parallel sides, while the subsections are connected to each other by the free sides of the said quadrangles with the formation along their outer and inner surfaces directed to one side at an angle to the longitudinal axis of the circular sector of the wave-shaped helical surfaces in the form of pockets that have different shapes and sizes , the distance between the fold lines is equal to the sum of the lengths of the perimeters of the geometric shapes of the pockets, in addition, four rectangular sections are made of one whether there are more strips bent in a wave-like fashion along bend lines arranged at an angle to their longitudinal edges with the formation of screw surfaces in the form of pockets of the outer surface and pockets of the inner surface of the wave-like shape along the outer and inner surfaces of one-sided angles of 10-80 °, while pockets have various shapes and sizes.

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

The novelty lies in the fact that the working chamber is made with a curved helical surface along the inner perimeter in the form of wave-shaped pockets, which expands technological capabilities, with the same dimensions with a working chamber made in the form of a torus, technological capabilities expand and the path increases (length ) traffic feed components in a square working chamber, because the length of circumference of the torus (circle) diameter D is equal to L ₁ = πD, while the length of the perimeter of a square is equal to 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 and since with the same dimensions (the area occupied by the units) with the working chamber made in the form of a torus, expanding technological capabilities and increasing the path (length) of the movement of feed components in a square working chamber.

The novelty is seen in the fact that the pockets of the working chamber are made in the form of a wave, of 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 extends technological capabilities, the working chamber is mounted from four sections rigidly connected alternately to each other, made in the form of a circular sector with four rectilinear sections with a wavy helical surface along the inner perimeter in the form of pockets of a wavy shape, which provides not only intensification of interaction between the components of feed, increase productivity, but also the expansion of technological capabilities.

The novelty of the proposal lies in the fact that wave-shaped 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 ensures 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, different in area and size, so 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 around the entire perimeter of the working chamber, the feed section varies not only in shape but also in area, which provides alternate compression and expansion of 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 whose walls are not only inclined to each other, but also to the direction of rotational movement of the feed components moving under the influence of vibration in planes perpendicular to the bore of the working chamber, which complicates the trajectories of their movement and increases the intensity of feed preparation and expands technological capabilities.

The novelty also lies in the fact that when the vibrator is installed horizontally (in contrast to 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 wave-like shape of all eight sections inclined to each other, which expands the technological capabilities and increases the productivity of cooking fodder feed.

The vibration device for mixing bulk materials (Fig. 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 (Fig. 2) with a screw surface along the inner perimeter (Fig. 3) in the form of pockets of a wave-like shape and is mounted from four sections 6, 7, 8, 9 rigidly alternately connected to each other, made in the form of a circular sector with four rectilinear sections 10, 11, 12, 13 (Fig. 2).

Sections 6, 7, 8, 9 are made in the form of a circular hollow sector (Fig. 4) with a wave-like multi-start screw surface of double curvature, equipped with screw grooves inside and outside at an angle to its axis in the form of pockets of a wave-like shape (Fig. 5) with centers curvatures located outside 14, 15, 16, 17, 18, 19, and pockets of wave-like shape with centers of curvature located inside the cross section 20, 21, 22, 23, 24, 25 of the circular hollow sector, and mounted from subsections 26 (Fig. . four). One of the subsections 26 in FIG. 4 is highlighted by solid thickened lines, made in the form of a ring 26, and the subsections are interconnected by known methods, for example, welding, adhesive, etc. Subsections 26 are interconnected by known methods, for example, welding, adhesive, etc., with the formation of helical grooves on the outer and inner perimeters inside and outside at an angle to the axis of sections 6, 7, 8, 9 in the form of pockets of a wavy shape with centers of curvature located outside and inside the cross section of a circular hollow sector - sections 6, 7, 8, 9.

Pockets of a wave-like shape on the outer surface 14, 15, 16, 17, 18, 19 (Fig. 5) and pockets of a wave-like shape on the inner surface 20, 21, 22, 23, 24, 25 around the perimeter of sections 6, 7, 8, 9 can be different not only in shape but also in size.

Each of the subsections 26 is made of a strip 27 (Fig. 6), bent in a wave-like fashion along the fold lines 28 located at equal angles α to the longitudinal edges of the strip 27 and placed at equal distances L between the fold lines 28. The distance L is equal to the sum of the lengths of the perimeters of the geometric figures pockets of the inner and outer surfaces, namely, the distance between points AB, BB, BB, GD, DE, EA (Fig. 5).

Thus, each of the subsections 26 is made in the form of a ring (Fig. 4) and is mounted from a strip 27 (Fig. 6, Fig. 7), on which rectangles 28 are marked (one of the rectangles shown in Fig. 6 with a double line) and lines fold 29, placed from each other at equal distances equal to the scan length of the perimeter of the wave-like pockets at distances L and at an angle α to the longitudinal edges of the strip 27.

On strip 27, trim lines 30 of the edges of strip 27 shown in FIG. 6 dash-dot line with two dots. After marking along the trim line of the edges 30, sections of the strip 27 (in FIG. 6 these sections of the strip 27 are shaded) are cut off and the strip 27 takes on the form shown in FIG. 7, in which the fold lines 29 of the strip 27 are different in length L ₁ , L ₂ , L ₃ , L ₄ , L ₅ , L ₆ with the formation of different-sized quadrangles with two parallel sides — fold lines 29 parallel to each other. The strip 27 (Fig. 7) after trimming the edges of the rectangles 28 along the trim line 30 is bent in a straight line (Fig. 8), placed at an angle α to the edges of the strip 27 with the formation of wavy surfaces AB, BB, C-D , G-D, D-E, EA, and then collapses into a ring 26 (Fig. 9) with a curved wavy surface. The wave-like strip after folding into a ring 26 is connected by known methods, for example by welding, soldering, etc., along the transverse edges 31 and 32 (Fig. 7, Fig. 8) of the strip 27 with the formation of a subsection 26 in the form of a ring.

Thus, the subsections 6, 7, 8, 9 (Fig. 3, Fig. 4) are made in the form of a circular sector and are made around the perimeter in the form of a multi-starting wavy helical surface of a curved shape at an angle to the axis of the subsections.

Sections 6, 7, 8, 9 (Fig. 4, Fig. 5) in the form of a hollow circular sector with a wavy helical surface along its inner and outer perimeter and the formation of wavy pockets and unidirectional multi-helical helical lines on their inner surfaces can be made and in a different way.

Four hollow rectilinear sections 10, 11, 12, 13 (FIG. 10, FIG. 11) with wave-shaped pockets, for example section 10, are made of at least one strip 33 connected along the longitudinal edges 34 (shown in dashed and dotted in FIG. 10 line), and is made around the perimeter in the form of a multiple-helical surface with helical grooves inside and outside in the form of pockets of a wave-like shape at an angle of 10 ° -80 ° to the axis of the rectilinear section, for example 10, with the centers of curvature of the pockets of a wave-shaped screw surface located alternately outsidein its cross-section. Thus, each of the four hollow rectilinear sections 10, 11, 12, 13 (Fig. 10, Fig. 11) is made of at least one strip 33 connected along the longitudinal edges 34 (shown in Fig. 2 by a dash-dot line) by known methods, for example by welding, with the formation on the outer and inner surfaces directed to one side at an angle of 10 ° -80 ° screw surfaces in the form of pockets of a wavy shape on the inner surface 35, 36, 37, 38, 39, 40 and pockets of a wavy shape outer surface 41, 42, 43, 44, 45, 46, which are empty around the perimeter body rectilinear sections can be different not only in shape but also in size. The strip 33 (Fig. 12, Fig. 13) is bent in a wave-like fashion along straight lines 35 located at equal angles α to the edges 34 of the strip 33 and placed at a distance L between the fold lines 34. The distance L is equal to the sum of the lengths of the perimeters of the geometric shapes of the pockets of the inner and outer surfaces. The strip 33 after a wave-shaped bend (Fig. 13) is folded into cylindrical coils (Fig. 14), connected to each other along the longitudinal edges 34 by known methods in a hollow rectilinear section.

A vibration device for mixing bulk materials works as follows.

The perturbing force of the vibrator 3 is transmitted through the walls of the working chamber 1 to the feed component particles inside the working chamber 1. Under the influence of vibration, the particles of the components rotate in planes perpendicular to the axis of symmetry of the hollow working chamber 1 and wave-shaped pockets around its perimeter. The presence of wave-like pockets around the 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 path of the feed components inside the working chamber 1, the productivity of preparation of feeds increases, 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 movement of feed components, i.e., there is an increase in feed preparation productivity. The presence of wavy 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 their moving along the bore 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 the vibrating device for mixing bulk materials in the form of a square, the surface of which is equipped with unidirectional helical lines and screw surfaces, in the form of pockets of a wave-like shape, which provide a change in the direction of flow of feed components and the expansion of technological capabilities.
