Description

The invention relates to a device for the preparation of feed, in particular mixing coarse, juicy, watery and concentrated feed.

Known drum feed mixer (AS USSR No. 1666173, class B01F 19/02, 1987), containing a working chamber with helical surfaces, consisting of sections, each of which is made of identical in area plates having the shape of equilateral triangles connected in series along the perimeter of the sections with each other with their bases with the formation along the perimeter of the working chamber of multi-start helical surfaces of equal pitch with the same number of strokes.

A disadvantage of the known device is the large dimensions of the device in length and limited technological capabilities due to insufficient mixing intensity.

Closest to the proposed invention is a device for the preparation of feed (patent No. 2028070, class A23N 17/00, 1995) containing a bed, a drive and a working chamber, consisting of sections made in the form of a straight triangular prism formed by a cube cross-section along diagonals, with the same-named ribs of adjacent sections connected at right angles.

A disadvantage of the known device is the large dimensions of the device in length and limited technological capabilities due to insufficient mixing intensity.

The technical result of the task is to reduce the dimensions in length and expand technological capabilities.

The technical result is achieved by the fact that in a feed preparation device comprising a bed, a working chamber made of sections mounted on it with a drive, a working chamber is made of a toroidal shape from sections mounted from strips bent to one side in straight lines placed at an angle to the edges of the strips, with the 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 bases 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 there 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 the mentioned triangles with the formation of the outer and inner the surface of the toroidal working chamber directed towards each other broken lines and helical surfaces located at an angle not only to each other, but also to the axis of the toroidal working chamber.

According to the patent technical literature, no technical solution was found that is similar to the claimed one, which makes it possible to judge the inventive device for preparing feed.

The novelty of the invention lies in the fact that the execution of the working chamber of a toroidal shape ensures the transfer of disturbing forces from the vibrator to the feed components and changes under the influence of differently inclined walls in the form of triangles of the direction of their movement in planes perpendicular to the passage section of the toroidal working chambers, which intensifies the process of mixing the feed components, provides reducing the dimensions of the device in length and expands technological capabilities.

The novelty of the proposal lies in the fact that along the inner surface of the toroidal working chamber are broken oppositely directed helical lines and helical surfaces, which increases not only the mixing intensity, but also the frequency, energy consumption of the interaction of the feed components. As a result, the productivity of mixing the feed components is increased, which reduces the preparation time of feeds and allows to reduce the dimensions of the device, to expand technological capabilities.

The novelty is due to the fact that the elements from which the toroidal working chamber is assembled are different in area, shape and size, so the intensity and efficiency of the preparation of feed increases, which means that the dimensions of the device are reduced, and technological capabilities are expanded.

The novelty is also due to the fact that the pitch of the broken helix is variable, i.e. varies around the perimeter of the working chamber, which intensifies the process of mixing the components of the feed, reduces the cooking time of the feed, and therefore, allows to reduce the dimensions of the device.

The novelty of the proposal also lies in the fact that around the entire perimeter of the toroidal working chamber, the passage section varies not only in shape but also in area, which provides alternate compression and expansion of the load masses in each section of the toroidal working chamber, which means increased productivity and cooking efficiency feed, which reduces the size of the device and extends the technological capabilities.

The invention is illustrated by drawings, where in Fig.1 schematically shows a device for the preparation of feed; figure 2 - toroidal working chamber, top view; figure 3 is a section aa in figure 2; figure 4 - section of the toroidal working chamber, axonometric projection; 5 is a strip with marked straight lines; figure 6 - assembly diagram of the toroidal working chamber; Fig.7 is a section bB in Fig.2; in Fig.8 is a section bb in Fig.2; figure 9 is a cross section GG in figure 2;

The device for preparing feed (Fig. 1) consists of a bed 1, on which a toroidal working chamber 4 is attached and equipped with a vibrator 3 by means of elastic elements 2. Loading and unloading devices are not shown in the drawings.

The toroidal working chamber 4 is mounted (Fig. 2, 3) from sections 5 (Fig. 4) highlighted in Fig. 2 by double lines 49-71- (29) - (91) and 70-48- (90) - (28 ) Section 5 is made of strip M (FIG. 4, FIG. 5), bent to one side along straight lines A, B, C, G, D, E, placed at an angle to the edges of strip M with the formation of alternating different sizes of equilateral 6 , 7, 8, 9 and isosceles 10, 11, 12, 13 triangles. At the same time, on the two sides of the largest equilateral triangle 7, two identical isosceles triangles 11 and 12 are placed with their bases (double lines in FIG. 5). The bases of the triangles 11 and 12 of the large sides are the same size, for example (Δ). Equilateral triangles 6 and 8 are placed to the lateral sides of triangles 11 and 12, the sides of which are smaller than the equilateral triangle 7 by (Δ), respectively. To the sides of the triangles 6 and 8, isosceles triangles 10 and 13 are placed with their bases, the bases of which are shown in Fig. 5 in triple lines, more than their sides also by (Δ). Equilateral triangle 9, the sides of which are smaller than triangles 6 and 8 by (Δ) and, accordingly, smaller than triangle 7 by (2 A), is placed to triangle 13. After bending the strip M along the lines A, B, C, D, D, E to one side, the ends of the strip M along the line L (shown in Fig. 4 by a triple line) are connected, for example, by welding to form section 5 (Fig. 4). Sections 5 are connected to each other by the free sides of triangles 6, 7, 8, 9, 10, 11, 12, 13, for example by welding (Fig.6) with the formation of a toroidal (Fig.1, 2, 3) working chamber 4. On the outside broken helical lines are formed on the inner surface of the toroidal chamber, for example, as shown in FIG. 2 by a thickened line: a closed broken helical line 14-15-16-17-18-19-20-21-22-23-24-25-26 -27-28-29-30-31-32-33-34-35-36-37-38-39-40-41-42-43-44-45-46-47-48-49-50-51 -52-53-14 and closed broken helix 54-55-56-57-58-59-60 = 61-62-63-64-65-66-67-68-69-70-71-72-73 -74-75-76-77-78-79-80-81-82-83-84-85-86-87-88-89-90-91-92-93-54 (in Fig. 2, invisible sections of screws x lines are shown by two parallel lines - the solid and dashed and invisible point sloping helix taken in the round bracket). As a result, on the inner and outer surfaces of the toroidal working chamber between the broken helical lines, helical surfaces are formed from triangles of different shapes, sizes and sizes, and the toroidal working chamber itself has a flow area that varies in shape, size of sides and cross-sectional area (Fig. 7 , 8, 9).

A device for preparing feed is as follows. The disturbing force of the vibrator 3 through the walls of the toroidal working chamber is transmitted to the particles of the feed components located inside the toroidal working chamber. The presence of flat multidirectional triangles in each of the sections of the toroidal working chamber changes the direction of movement of individual portions of the feed components moving under the influence of vibration in a plane perpendicular to the passage section of the toroidal working chamber, which intensifies the process of mixing the feed components. Due to the change in the flow cross section in shape and size, compression and rarefaction zones are formed in each cross section of the toroidal working chamber over the entire volume of the toroidal working chamber, which also intensifies the process of mixing feed components and allows, at the same performance, to reduce the dimensions of the device and production area occupied by the proposed device.

The execution of the working chamber of a toroidal shape with the formation along its inner surface of broken helical lines directed towards each other and helical surfaces in the form of triangles located at an angle not only to each other, but also to the axis of the toroidal working chamber, provides an intensification of the mixing processes of feed components, increases the frequency and energy intensity of the impact of these particles with each other and with the walls of the working column, reduces the time of preparation of feed and allows for the same given production telnosti reduce the dimensions of the device for preparation of feeds and reduce the occupied area of production as compared to prior art devices.
