Description

The invention relates to devices for the preparation of mortars and concrete mixtures.

Known concrete mixer (AS No. 11999622, class B28C 5/14 1982), comprising a housing with loading and unloading openings and with a working mixing body, longitudinally located in it and equipped with a vibratory tray under the unloading hole.

A disadvantage of the known device is the insufficient intensity of the interaction of the components of the solutions and concrete mixtures, limited technological capabilities.

Closest to the proposed invention is a device for the preparation of solutions with a toroidal working chamber (RF patent No. 2467870, class B28C 5/00, publ. 04/20/2012, bull. No. 11 2011), containing elastically mounted on the base, equipped with a drive a working chamber made in the form of a torus with a wave-like multi-starting helical surface of double curvature, provided with helical grooves inside and outside the working chamber at an angle to its axis in the form of pockets of curvilinear shape with centers of curvature located outside and inside the transverse cheniya working chamber.

The disadvantages of the known device with a toroidal working chamber are limited technological capabilities due to the fact that they are produced with insufficient intensity and insufficient energy consumption of the interaction of the components of mortars and concrete mixtures 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 movement of the components of the solutions and concrete mixtures in the working chamber.

The technical solution is achieved by the fact that in the installation for the preparation of solutions with a square working chamber containing a working chamber elastically mounted on the base and equipped with a drive, the working chamber is hollow, in the form of a square, with a wavy helical surface along the inner perimeter with wavy pockets, while the working chamber is mounted from four hollow sections rigidly connected alternately to each other, made in the form of a hollow circular sector, with four hollow straight lines sections, moreover, four sections, made in the form of a hollow circular sector with a wave-like multi-start helical surface of double curvature, equipped with helical grooves inside and outside the circular sector at an angle to its axis in the form of pockets of a wave-like shape with centers of curvature located outside and inside the cross section circular sectors, mounted from subsections, each of which is made of a strip rolled into a ring to form different-sized quadrangles with two parallel sides parallel to each other, while the subsections are connected to each other by the free sides of the said quadrangles in the form of a hollow circular sector, with the formation on the 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 of a wavy shape on the outer and inner surfaces, which along the perimeter of the circular sector can be different not only in shape but also in size, while the distance between the lines the folds is equal to the sum of the lengths of the perimeters of the geometric figures of the pockets of the inner and outer surfaces, and the four hollow rectilinear sections along the perimeter are made of one or more stripes bent in waves along the bend lines placed at an angle to their longitudinal edges, with the formation along the outer and inner surfaces directed to one side at an angle of 10 ° -80 ° of screw surfaces in the form of pockets of the outer surface and pockets of the inner surface of a wavy shape, while the shape and dimensions of the pockets on the inside the surfaces may differ from the shape and size of the pockets along the outer surface, and along the perimeter of the rectilinear section, the pockets can be different not only in shape but also in size.

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 for the preparation of solutions with a square working chamber.

The novelty lies in the fact that the working chamber is made in the form of a square with a curved helical surface along the inner perimeter in the form of pockets of a wave-like shape, which expands the technological capabilities, since with the same dimensions (in width and length) with the working chamber made in a torus, expanding processing capabilities and increases the path (length) of movement of workpieces and particulate working media in the working chamber of the square, because the length of the torus perimeter (circumference) of diameter D equal L ₁ = πD, while the length n 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 connected alternately to each other, made in the form of a circular sector with four rectilinear sections, which expands technological capabilities, since with the same dimensions (the area occupied by the installations) with the working a chamber made in the form of a torus, technological capabilities expand and the path (length) of the movement of the components of mortars and concrete mixes in a square working chamber increases.

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 expands the technological capabilities.

The novelty is due to the fact that the working chamber is made in the form of a square and 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 wavy-shaped pockets, which provides not only intensification the interaction of mortar components and concrete mixtures, increasing productivity, but also expanding technological capabilities.

The novelty of the proposal lies in the fact that on the inner surface of the working chamber, wave-shaped surfaces are formed, which along the perimeter can be different not only in shape but also in size, which provides a change in the direction of movement of the components of mortars and concrete mixtures, as a result, productivity increases and expand 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 size and area, so the intensity and productivity of the preparation of solutions increases, and technological capabilities expand.

The novelty of the proposal also lies in the fact that the entire cross-section along the entire perimeter of the working chamber changes not only in shape, but also in area, which provides alternate compression and expansion of the flows of mortar components and concrete mixtures in each section of the working chamber, which means increased productivity and expansion 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 flows of the components of the solutions and concrete mixtures increases, the process of preparing solutions 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 the rotational movement of the components of the solutions moving under the influence of vibration in the planes perpendicular to the bore of the working chamber, which complicates the trajectories of their movement and increases the intensity of the preparation of solutions expands technological capabilities.

The novelty also lies in the fact that when the vibrator is installed horizontally (unlike the analogue of the RF patent No. 2467870, class B28C 5/00, published on 04/20/2012, bulletin No. 11, in which the vibrator is installed vertically), the components mortars and concrete mixtures that circulate inside the working chamber in planes perpendicular to the axis of symmetry of the working chamber, receive additional movement from the tilted walls of the pockets of the wave-like shape of all eight sections, which expands technological capabilities and increases production loneliness.

Installation for the preparation of solutions with a square working chamber (figure 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 installed on the base 5.

The working chamber 1 is made in the form of a square (Fig. 2) with a helical 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 circular sector with four rectilinear sections 10, 11, 12, 13 (figure 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 indicated by solid thickened lines) is made in the form of a ring 26 (Fig. 9) and 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 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 is shown in Fig. 6 by 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 the strip 27 also marked are the cropping lines 30 of the edges of the strip 27, shown in FIG. 6 with a dash-dot line with two points. 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 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 at the same time of different sizes of 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 wave-like fashion along straight lines (Fig. 8) placed at an angle α to the edges of the strip 27 to form undulating 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 the 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 (Fig. 9) .

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-start 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 wave-like helical surface along its inner and outer perimeter and the formation of wave-shaped 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 are 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 outside and inside 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 the outer surface 41, 42, 43, 44, 45, 46, which are around the perimeter of voids White straight 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 the sum of the lengths of the perimeters of the geometric figures 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 into a hollow rectilinear section.

Installation for the preparation of solutions with a square working chamber works as follows.

The perturbing force of the vibrator 3 is transmitted through the walls of the working chamber 1 to the components (cement and inert materials) of the mortar or concrete mixture, as well as to the mixing water located inside the working chamber 1 and continuously fed into the working chamber by means of a loading device of known design (not shown in the drawings) . The components of mortars and concrete mixtures under the influence of vibration rotate in planes perpendicular to the axis of symmetry of the hollow working chamber 1 and pockets of a wavy shape around its perimeter. The presence of wavy pockets around the perimeter of the working chamber 1 changes the direction of movement of the components of the mortars and concrete mixtures, as a result of which they not only acquire directional movement from loading to unloading, but also compression zones are formed along the entire length of the path of movement inside the working chamber 1, productivity increases, expand technological capabilities. The components of mortars and concrete mixtures not only intensively interact with each other, mixing, but also under the influence of vibration make a rotational movement in a plane perpendicular to the bore of the working chamber 1. Since the length of the working chamber 1 is the size of the cross section, shape and location, then aggravated movement of the components of solutions and concrete mixtures, that is, there is an increase in the productivity of the preparation of solutions and concrete mixtures. The presence of wavy helical surfaces and helical lines around the perimeter of the working chamber ensures the movement of the components of mortars and concrete mixtures 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 movement along the passage section of the working chamber 1 from loading to unloading. When the components of mortars and concrete mixtures move along the bore of the working chamber 1 due to changes in the bore in shape and size, compression and rarefaction zones are formed alternately in each section of the working chamber 1 over its entire volume, which also intensifies the process of preparing mortars and concrete mixtures and expands technological capabilities.

The technical and economic advantages of the installation for the preparation of solutions with a square working chamber arise due to the design of the working chamber in the form of a square, the surface of which is equipped with unidirectional helical lines and helical surfaces in the form of pockets of a wave-like shape, which provide a change in the direction of motion of the flows of the components of the solutions and concrete mixtures expansion of technological capabilities.
