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 education on the outer and inner surfaces of the toroidal working chamber, directed towards each other broken lines of helix and screw th surfaces arranged at an angle to one another

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 vibrating device for mixing bulk materials containing an elastic chamber mounted on the base, equipped with a drive, the working chamber is hollow with a curved helical surface, while the chamber is mounted from four hollow sections rigidly connected in a circle to each other , each section is made of at least one strip bent in straight lines placed at an angle to its edges with the formation of the same or different in size four squares with two parallel sides in the form of bending lines located on the strip at equal or different distances from each other, the sections are connected to each other by the free sides of the quadrangles, and the strip is folded into cylindrical coils with the formation on the outer and inner surfaces of the sections of helical lines having cross-section curved surfaces in the form of semicircular pockets of the same or different shapes and sizes, while the distance between the bending lines of the strip is equal to the sum of the lengths of the perimeters of geometric shapes pockets.

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 hollow with a curved helical surface, while the chamber is mounted from four hollow sections rigidly connected in a circle to each other, which expands technological capabilities, with the same dimensions as the torus made in the form of a torus expanding technological capabilities and increasing the path (length) of the movement of the feed components in the proposed working chamber, since the length along the perimeter of the torus (circle) of diameter D is L ₁ = π · D, and the length along the perimeter of kva the drata is L ₂ = 4D (L ₂ > L ₁ ).

The novelty is also due to the fact that the working chamber is mounted from four hollow sections rigidly connected in a circle to each other, each section is made of at least one strip bent in straight lines placed at an angle to its edges with the same or different sizes of quadrangles with two parallel sides in the form of bending lines located on the strip at equal or different distances from each other, the sections are connected to each other by the free sides of the quadrangles, which extends the technology the possibility and the path (length) of the movement of the feed components in the proposed working chamber increases.

The novelty is that each section is made of at least one strip bent along straight lines placed at an angle to its edges with the formation of the same or different in size quadrangles with two parallel sides in the form of bending lines located on a strip on equal or different distances from each other from the same strip, which expands technological capabilities.

The novelty also lies in the fact that the semicircular pockets around the perimeter of the working chamber can be the same or different shapes and sizes, which expands the technological capabilities.

The novelty is also due to the fact that the distances between the bending lines of the strip are equal to the sum of the lengths of the perimeters of the geometric figures of the pockets, which expands the technological capabilities.

The novelty of the proposal lies in the fact that curved 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 movement of the 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, 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, the walls of which 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 (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 circulating inside the working chamber in planes perpendicular to the axis of symmetry of the working chamber, receive additional movement from the walls of curved pockets of all eight sections inclined to each other, which expands technological capabilities and increases the productivity of preparation for ohm

The novelty also lies in the fact that each section is made of at least one strip bent in straight lines placed at an angle to its edges with the formation of the same or different in size quadrangles with two parallel sides in the form of bending lines located on the strip at equal or different distances from each other, the sections are connected to each other by the free sides of the quadrangles, and the strip is folded into cylindrical turns, with the formation of helical lines along the outer and inner surfaces of the sections, curved surfaces in the form of semicircular pockets of the same or different shape and size, the distance between the bending lines of the strip being equal to the sum of the lengths of the perimeters of the geometric shapes of the pockets, which expands the technological capabilities and increases the productivity of preparing feed.

The vibratory 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) hollow with a curved helical surface (Fig. 3) in the form of pockets of a curvilinear shape and mounted from four hollow sections 6, 7, 8, 9 rigidly connected in a circle to each other with four rectilinear sections 10, 11, 12, 13 (Fig. 2).

Sections 6, 7, 8, 9 are made (Fig. 4) with a curved screw surface along the inner perimeter in the form of pockets of curved shape 14, 15, 16, 17, 18, 19 (Fig. 5) and mounted from strip 20 (Fig. 6), on which rectangles 21 and fold lines 22 are marked, placed at equal distances from each other, equal to the length of the scan of the perimeter of curved pockets, for example, for pockets 14, 15, 16, 17, 18, 19 at distances L and at an angle α to the edges of the strip 20.

On the strip 20, trim lines 23 of the edges of the strip 20 shown in FIG. 6 dash-dot line with two dots. After marking along the line of trimming of the edges 23, sections of the strip 20 (in FIG. 6 these sections of the strip 20 are shaded) are cut off and the strip 20 takes on the form shown in FIG. 7, in which the fold lines 22 of the strip 20 are different in length L ₁ , L ₂ , L ₃ , L ₄ , L ₅ , L ₆ , with the formation of quadrangles of different sizes with two parallel sides — fold lines 22 parallel to each other . The strip 20 (Fig. 7) after trimming the edges of the rectangles 21 along the trim line 23 is bent along straight lines placed at an angle α to the edges of the strip 20 to form curved surfaces 24 (Fig. 8) with edges 25 and 26, and then rolled into a ring -subsection 27 (Fig. 9) with a curved inner surface in the form of pockets 14, 15, 16, 17, 18, 19. Edges 25 and 26 of strip 20 after folding into a subsection ring 27 are connected by known methods, for example, welding, soldering and etc. with the formation of a subsection ring 27. Then, the subsections 27 are connected to each other by known methods in the form of sections 6, 7, 8, 9.

Thus, sections 6, 7, 8, 9 (Fig. 2, Fig. 3) are made with a multiple helical surface and helical lines with helical grooves inside the sections 6, 7, 8, 9 in the form of curved pockets at an angle to their longitudinal axis.

Sections 6, 7, 8, 9 (Fig. 4, Fig. 5) with a curved helical surface along its inner and outer perimeters and the formation on its inner surfaces of pockets of a curved shape and unidirectional multi-helix lines can be made in another way.

Four hollow rectilinear sections 10, 11, 12, 13 (FIG. 10, FIG. 11) with curved pockets, for example section 10, are made of at least one strip 28 connected along the longitudinal edges 29 (shown in FIG. 10 by a dash-dot line) by known methods, for example, by welding, with the formation of helical lines on the outer and inner surfaces (in Fig. 10, part of one of the helical lines is shown by a thickened line 30-31-32-33-34-35-36) and helical surfaces ( Fig. 11) curved shape in the form of pockets of the inner surface of a semicircular shape 37, 38, 39, 40, 41, 42.

The strip 28 (Fig. 12, Fig. 13) is bent along straight lines 43 at equal angles β to the edges of the strip 29 placed at distances equal to the scan length of the perimeter of curved pockets, for example, for pocket 42 at distances L ₁ .

The strip 28 after bending (Fig. 13) is folded into cylindrical coils (Fig. 14), connected to each other along the longitudinal edges 29 by known methods, for example by welding, into a hollow rectilinear section, for example 10, 11, 12, 13.

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

Vibration device for the preparation of solutions works as follows.

The perturbing force of the vibrator 3 is transmitted through the walls of the working chamber 1 to the particles of the 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 curved shape along its perimeter. The presence of curved multidirectional elements, including 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 path length of the 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 movement 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, which contributes not only to complicate the trajectories of their movement, but also to their movement 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 a vibrating device for mixing bulk materials from sections rigidly connected in a circle to one another, the surface of which is provided with unidirectional helical lines and screw surfaces, in the form of pockets of a curved shape, which provide a change in the direction of movement of the component flows feed and technological expansion.
