Description

The invention relates to devices for mixing, in particular to devices of continuous action 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 minimum is equal to 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 invention is a device for the preparation of feed (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 are located their 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 smaller equilateral triangles differ from the sides of large equilateral triangles by the same linear value, and the sections are connected to each other by the free sides of these triangles with the formation of the outer and internal surfaces of the toroidal working chamber directed towards each other broken lines 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 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 the installation of vibration for mixing bulk materials containing an elastic chamber mounted on the base, equipped with a drive, the working chamber is hollow, in the form of a square, with the formation of triangular helical multi-threaded helical surfaces and unidirectional multi-threaded along its inner and outer perimeter helical lines and is mounted from four hollow sections rigidly connected alternately to each other, made in the form of a hollow circular sector with four three hollow rectilinear sections, and four sections, made in the form of a hollow circular sector, are mounted from subsections, each of which is made of a strip bent alternately in different directions along straight lines in the form of fold lines located on the strip at equal distances from each other and placed at an angle to the edges of the strip with the formation of different sizes of quadrangles with two parallel sides located on the strip alternately and parallel to each other, and rolled into a ring in the form of a subs sections, and subsections are connected to each other by the free sides of the mentioned quadrangles with the formation of a hollow circular sector, with triangular helical multiple surfaces and unidirectional multi-helical lines, 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 the same parallelograms located on the strip alternately in opposite directions, while the strip is folded into cylindrical coils, connected to each other along the longitudinal edges to form the inner surface of the helical polygons pockets triangular shape, and on the outer surface - polygonal unidirectional helical lines.

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 installation of vibration for mixing bulk materials.

The novelty is that the working chamber is made hollow in the form of a square, with the formation along its inner and outer perimeters of multi-helical surfaces of triangular shape and unidirectional multi-helical lines, which expands technological capabilities with the same dimensions over the occupied area of the vibration unit with the working camera, made in the form of a torus, and increases the path (length) of the movement of the feed components in the square working chamber, since the length along the perimeter of the torus (circle) diam D is equal to 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 , 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 of a triangular shape from at least one strip, which expands the technological capabilities.

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 compression ratio 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 trajectories movement and 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, 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 a triangular shape inclined to each other of all eight sections, which expands technological capabilities and increases the productivity I feed.

Vibrating installation 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 hollow, in the form of a square (figure 2), with the formation on its inner and outer perimeters of multi-helical surfaces of a triangular shape, as well as unidirectional multi-helical lines, and is mounted from four sections 6, 7, rigidly connected alternately to each other , 8, 9, made in the form of a circular sector with four rectilinear sections 10, 11, 12, 13 (figure 2).

Sections 6, 7, 8, 9 (for example, section 6 is shown in Fig. 4) are made in the form of a hollow circular sector and are mounted from subsections 14 (one of the subsections 14 in Fig. 4 is marked by solid thickened lines). interconnected by known methods, for example, by sticky welding, 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 15-16-17-18-19-20-21- 22-23-24-25-26-27-28-29-30-31) and screw surfaces of a triangular shape (Fig. 5) in the form of pockets of a triangular shape on the inner surface and the outer surface.

Each of the subsections 14 is made in the form of a circular sector (Figs. 4 and 5) and is mounted from a strip 32, on which rectangles 33 are marked, along the diagonals of which there are fold lines 34 at equal distances from each other, these diagonals - the fold line of strip 32 is shown in Fig. 6 with a thickened line 33. On the strip 32, trim lines 35 of the edges of the strip 32 shown in Fig. 6 with a dot-dash line with two points are also marked. After marking along the trim line 35, the sections of the strip 32 (in FIG. 6 these sections of the strip 32 are shaded) are cut off and the strip 32 takes on the form shown in FIG. 7, in which the fold lines 34 of the strip 32 are different in length L ₁ , L ₂ , L ₃ , L ₄ , L ₅ , L ₇ , L ₈ , L ₉ , L ₁₀ , L ₁₁ , L ₁₂ , L ₁₃ , L ₁₄ , L ₁₅ , L ₁₆ . The strip 32 (Fig. 8) after trimming the edges of the rectangles 33 along the trim line 35 is bent alternately in different directions along straight lines placed at an angle to the edges of the strip 32 to form different-sized quadrangles with two parallel sides, i.e. diagonally 34 squares 33 parallel to each other, and then collapsed into a ring 14, as shown in Fig.9. The edges 36 and 37 of the strip 32 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.

Thus, sections 6, 7, 8, 9 (Figs. 2, 4) are made around the perimeter in the form of a multi-helical surface with helical lines around the perimeter (one of the helical lines is shown in Fig. 4 by a thickened line 15-16-17-18- 19-20-21-22-23-24-25-26-27-28-29-30-31) and screw grooves inside the sections in the form of pockets of a triangular shape at an angle to the axis of the sections.

Sections 6, 7, 8, 9 (FIG. 2) are hollow with the formation on their outer and inner surfaces of multi-helical triangular helical surfaces and unidirectional multi-helical helical lines can be made in another way.

Four hollow rectilinear sections 10, 11, 12, 13 (FIGS. 10-11) with triangular pockets, for example section 10, are made of at least one strip 38, bent along straight lines 59, placed at equal distance "L "From each other and at the same angles α to the edges of the strips 39, 40 with the formation of the same parallelograms 41 and 42, located alternately in opposite directions (Fig.12 and 13).

The strip 38 after bending along the straight lines 59 is folded into cylindrical coils (Fig. 14), connected to each other along the longitudinal edges 39 (Fig. 10) by known methods, for example, by welding. In Fig.10, the connection line of the longitudinal edges of the turns of the strip 38 is shown by a dash-dot line with two points 39, with the formation on the outer surface of unidirectional, broken helical lines, and on the inner surface of the pockets of a triangular shape (in Fig.10 one of the helical lines is shown by a thickened line 40 -41-42-43-44-45-46-47-48-49-50-51) and screw surfaces (11) of a triangular shape in the form of pockets of the inner surface 52, 53, 54, 55, 56, 57, 58.

Hollow rectilinear sections, for example, 10, 11, 12, 13 with triangular pockets are rigidly connected alternately with hollow sections 6, 7, 8, 9 with triangular pockets (figure 2) along the lines of joining 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 triangular pockets along its inner perimeter.

Installation vibration for mixing bulk materials is as follows.

The perturbing force of the vibrator 3 through the walls of the working chamber 1 is transmitted 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 triangular shape around its perimeter. The presence of curved multidirectional elements, including pockets of a triangular 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 path feed components 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 the installation of vibration 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 triangular 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 triangular shape along its perimeter, as well as due to the fact that then when the feed components move along the feed-through section of the working chamber 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 throughout its volume, which intensifies the process of preparing feeds and expands technological capabilities.
