Description

The invention relates to devices for mixing, in particular to continuous drum mixers for mixing components of coarse, juicy, watery and concentrated feeds, and can be used for mixing bulk materials.

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.

The disadvantages of the known device are 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 patent. 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.

The disadvantages of the known device are 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.

The technical solution is achieved by the fact that in the first embodiment of the installation for mixing feed components containing a bed, a drum consisting of sections mounted on it with the possibility of rotation and a drive according to the invention, the drum is made of at least three strips twisted along helical lines in the longitudinal and transverse directions, according to the second embodiment, in an installation for mixing feed components comprising a bed, a drum consisting of sections and a drive, according to the invention, rotatably mounted on it The th drum is made of at least three helical strips of curved concave or convex shape, described by curves of various orders and degrees of curvature with centers located outside and inside the cross section of the drum.

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 design of the installation for mixing feed components.

The novelty is due to the fact that such a design allows us to provide not only a smooth axial movement of the components of the feed from loading to unloading with a horizontal axis of rotation of the drum, but also to ensure intensive mixing.

The novelty lies in the fact that due to the internal helical surfaces of double curvature, the vectors of the speed of movement of the feed components during transportation from load to unload change, which helps to intensify the mixing process and extends technological capabilities.

The novelty is seen in the fact that the drum is made of at least three strips, which simplifies manufacturing and expands technological capabilities.

The invention is illustrated by drawings, where: in Fig.1 shows a General view of the installation for mixing feed components; figure 2 is a section aa in figure 1; figure 3 - drum, General view; figure 4 is a section bB in figure 3 (M2: 1); figure 5 is a view of the strip according to the first embodiment after twisting its ends relative to the horizontal axis O ₁ -O; figure 6 is a view of the strip according to the first embodiment after twisting it on the mandrel; Fig.7 is a section bb in Fig.6; on Fig - section bb in Fig.6 with the alignment of the edges of the two strips; figure 9 is a section bB in figure 3, the helical strip according to the second embodiment are described by concave curves in which the centers of curvature are located outside the cross section of the drum; figure 10 is a section bB in figure 3, the helical strip according to the second embodiment are described by convex curves in which the centers of curvature are located inside the cross section of the drum.

The proposed installation for mixing feed components consists of a frame 1, made in the form of a welded frame. A drive of the main movement is fixed on the bed, consisting of an electric motor 2, a gearbox 3 and four roller bearings 4. The drum 5 is equipped with two rims 6, which rely on the roller bearings 4. A means for loading 7 and unloading 8 is mounted on the bed 1.

The drum 5 according to the first embodiment is made of strips 9, 10, 11 (Fig. 3, Fig. 4) twisted in longitudinal and transverse directions along helical lines, i.e. pre-twisted in the longitudinal direction of the strip relative to the axis O ₁ -O ₁ , for example 9 (figure 5), is placed on the mandrel 12 (figure 6) and bent (figure 6, figure 7) so that the edges 13 and 14 of the strip 9 were rolled up along helical lines. After that, the strip 9 is deformed and removed from the mandrel or fixed on the mandrel 12. The remaining strips 10 and 11 are processed in the same way. Next, the three strips 9, 10, 11 so deformed in this way, after combining, for example, the edges 13 and 14, are connected, for example, by welding. As a result, three smooth helical lines 15-16, 17-18, 19-20 and three internal smooth grooves 21, 22, 23 are formed on the outer surface of the drum 5 (Fig. 3).

The drum 5 according to the second embodiment can be made unidirectional, hollow screw around the perimeter of three or more rolled in a vertical plane and sequentially interconnected along the length of the drum strips 24, 25, 26 curved concave or convex shape relative to the axis of rotation of the drum and described by curves of various orders and degrees of curvature, for example, by lines of second order of curvature:

- an ellipse x ² / a ² + y ² / b ² = 1;

- parabola y ² = 2 · p · x;

- hyperbola y = k / x.

Lines of the third order of curvature and higher:

- Cartesian leaf x ³ + y ³ -3 · a · x · y = 0;

- Agnesi curl y = a ³ · (α ² + x ² );

- stanoid y ³ = x ² (a + x) / (a-x);

- Pascal snail (x ² + y ² -2R · x) ^{2-a 2} · (x ² + y ² ) = 0, etc .;

and lines of the nth order of curvature - polynomials.

The connection lines of the bands rolled into a screw form a distinct unidirectional three-way and more screw drum.

The proposed installation works as follows.

Feed components are continuously loaded into the drum 5 through the loading means 7. When the drum rotates, the particles of the feed components move along helical lines and are discharged from the drum 5 into the means 8 for unloading.

Technical and economic advantages arise due to the creation of smooth spiral grooves in one direction on the inner surface, which not only expands technological capabilities, but also ensures the movement of components from loading and unloading with a horizontal axis of rotation of the drum.
