Description

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

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 a working chamber, resiliently mounted on the base, equipped with a drive, made in the form a torus with a wave-like multi-starting helical surface of double curvature, equipped with helical grooves inside and outside the working chamber at an angle to its axis in the form of curved pockets with centers of curvature located outside and inside the cross section of the working chamber.

A disadvantage of the known device with a toroidal working chamber is the limited technological capabilities due to the fact that it is 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.

Closest to the proposed vibration installation for the preparation of solutions with a square working chamber is a small-sized vibration installation for the preparation of solutions (RF patent No. 2464164, class B28C 5/00, publ. 04/20/2012, bull. No. 11, 2011), containing resiliently mounted on the base, equipped with a drive, a working chamber, equipped with a vibrator and made in the form of a torus with a multi-helical surface, equipped with helical grooves inside and outside the working chamber at an angle to its axis in the form of polygonal pockets in the form of p zlichnyh geometric shapes having four or more sides,

A disadvantage of the known small-sized vibratory installation for the preparation of solutions is the limited technological capabilities due to the fact that it is produced with insufficient intensity and insufficient energy consumption of the interaction of the components of the solutions 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 a vibrating installation for preparing solutions with a square working chamber containing a working chamber which is resiliently mounted on a base and equipped with a drive, the working chamber is hollow, in the form of a square, with a helical surface along the inner perimeter and multi-faceted pockets in the form of various geometrical figures, with four or more lateral sides and is mounted from four hollow sections rigidly connected, alternately with each other, made in the form of a hollow a circular sector with four hollow rectilinear sections, and four sections are made in the form of a hollow circular sector made of a strip rolled into a ring with a multifaceted surface and the formation of different-sized quadrangles with two parallel sides parallel to each other with the formation of subsections, while the subsections are connected to each other by the free sides of the said quadrangles in the form of a hollow circular sector made with a multiple helical surface equipped with helical grooves inside the circular sector at an angle to its axis in the form of pockets of polygonal shapes of various geometric shapes with four or more sides, the distance between the straight fold lines being equal to the length of each polygon element, and at least four hollow rectilinear sections are made of at least , from one strip bent in straight lines placed at an angle to the edges of the strip, with the formation of 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, with the formation on the outer surface of unidirectional broken helical lines, and on the inner surface - broken helical pockets of a polygonal shape in the form of various geometric shapes with four or more lateral sides, which can be perimeter be different not only in shape but also in size, while the distances between the fold lines are equal to each other and equal to the sum of the lengths of the perimeters of the geometric shapes of the pockets of the inner surfaces s.

According to the patent literature not found a technical solution similar to the claimed, which allows to judge the inventive step of the proposed vibration unit for the preparation of solutions with a square working chamber.

The novelty lies in the fact that the working chamber is made hollow in the form of a square with a curved helical surface along the inner perimeter in the form of pockets of a multifaceted shape, which expands technological capabilities, with the same dimensions with the working chamber made in the form of a torus, technological capabilities expand and the path (length) of movement of the workpieces and particles of the working media in the square working chamber increases, since the length along the perimeter of the torus (circle) of diameter D is L ₁ = πD, and the length along the perimeter of the quad 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 alternately rigidly connected to each other, made in the form of a circular sector with four rectilinear sections, which expands technological capabilities, and since with the same dimensions the working chamber made in the form torus, expanding technological capabilities and increasing the path (length) of the movement of the processed parts and particles of the working medium in a square working chamber.

The novelty is seen in the fact that the pockets of the working chamber are made in the form of geometric shapes of a polygonal shape from 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 hollow, in the form of a square, with a curved helical surface along the inner perimeter in the form of pockets of a multifaceted shape in the form of various geometric shapes with four or more sides, which provides not only the intensification of the interaction of particles of solution components and mixing water , increasing productivity, but also expanding technological capabilities.

The novelty of the proposal lies in the fact that polygonal 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 provides a change in the direction of movement of the particles of the solution and water components, 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 of different sizes and sizes, 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 particle flows of the components of solutions and water 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 particle fluxes of the components of the solutions and water increases, and the feed preparation process 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 particles of the components of the solutions and water moving under the influence of vibration in planes perpendicular to the bore of the working chamber, which complicates the trajectory of their movement and increases the intensity of the preparation of solutions and expands technological capabilities.

The novelty also lies in the fact that when the vibrator is installed horizontally (in contrast to its analogue, RF patent No. 2464164, class B28C 5/00, published on 04/20/2012, Bulletin No. 11, 2011), particle particle flows solutions and water circulating 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 the polygonal shape of all eight sections inclined to each other, which expands the technological capabilities and increases the productivity of the preparation of the solution s.

The vibration installation for the preparation of solutions with a square working chamber (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 in the form of a square (Fig. 2) with a polygonal screw surface along the inner perimeter (Fig. 3) in the form of pockets of a polygonal shape and is mounted from four sections 6, 7, 8, 9, rigidly connected alternately to each other, made in in the form of a circular sector with four rectilinear sections 10, 11, 12, 13 (figure 2).

Sections 6, 7, 8, 9 (Fig. 4) with a multifaceted helical surface along their inner perimeter are made of subsections 14 (one of the subsections in Fig. 4 is marked by solid thickened lines), interconnected by known methods, for example, welding, gluing 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 15-16-17-18-19-20-20-22-22-23) and polygonal helical surfaces in the form of various geometric shapes with four or more sides, for example, a rectangular nickname, trapezoid, rhombus, etc., in the form (5) the outer surface of the pockets 24, 25, 26, 27, 28, 29 and the inner surface of the pockets polygonal shape 30, 31, 32, 33, 34, 35.

Each of the subsections 14 is made in the form of a circular sector (Fig. 4, Fig. 5) and is mounted from a strip 36 (Fig. 6, Fig. 7), on which rectangles are marked, along the diagonals of which there are fold lines passing through points 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47. 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60 at distances from each other equal to the length of the side of the geometric figure, for example, as in Fig.6 at a distance L ₁ , L ₂ , L ₃ . The fold lines of the strip 36 are shown in FIG. 6 with a thickened line. On the strip 36 also marked are the trim lines 61 of the edges of the strip 36 shown in FIG. 6 with a dash-dot line with two points. After marking along the edge-cutting line 61, sections of the strip 36 (in FIG. 6 these sections of the strip 36 are shaded) are cut off and the strip 36 takes on the form shown in FIG. 7, in which the fold lines of the strip 36 are different in length L ₄ , L ₅ , L ₇ , L ₈ , L ₉ , L ₁₀ , L ₁₁ , L ₁₂ , L ₁₃ , L ₁₄ , L ₁₅ , L ₁₆ . L ₁₇ , L ₁₈ , L ₁₉ , L ₂₀ , L ₂₁ , L ₂₂ , L ₂₃ , L ₂₄ , L ₂₅ , L ₂₆ , L ₂₇ .

The strip 36 (Fig.7) after trimming the edges of the rectangles along the trim lines 61 is bent in straight lines - the fold lines 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47. 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, placed at an angle α to the edges of the strip 36 (Fig.6, Fig.8) with the formation of different sizes of quadrangles with two parallel sides - t. e. along the diagonals passing through the points 37-60 of the rectangles (Fig.6) parallel to each other, and then collapses into a ring 14 with a multifaceted surface, as shown in Fig.9. The transverse edges 62 and 63 of the strip 36 (Fig.6, Fig.7) 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 - ring 14 (Fig.9 4)

Thus, sections 6, 7, 8, 9 (Fig. 4, Fig. 5) are made around the perimeter in the form of a multiple helical surface with helical lines varying in diameter of the section in increments of the perimeter of the section, one of the helical lines is shown in FIG. 4 with a thickened line 15-16-17-18-19-20-21-22-23 and screw grooves inside and outside sections 6, 7, 8, 9 in the form of pockets of a polygonal shape, at an angle to the axis of sections 6, 7, 8 , 9.

Sections 6, 7, 8, 9 (Fig. 4, Fig. 5) with a screw surface along its inner and outer perimeter with the formation of pockets of a polygonal shape can be made in other ways.

Four hollow rectilinear sections 10, 11, 12, 13 (Fig. 10, Fig. 11) with pockets of a polygonal shape, for example, section 10, are made of at least one strip 64 connected along the longitudinal edges 65 (shown in phantom in Fig. 10 line) by known methods, for example, welding, with the formation of helical lines on the outer and inner surfaces (in Fig. 10, one of the helical lines is shown by a thickened line 66-67-68-69-70-71-72-73-74-75- 76-77) and screw surfaces (Fig. 11) of a rectangular shape in the form of pockets of the outer surface 78, 79, 80, 81, 82, 83 and pockets inside the bottom surface 84, 85, 86, 87, 88, 89.

Strip 64 (FIG. 12, FIG. 13) is bent along straight lines 90 at equal angles α to the longitudinal edges 65 of strip 64 placed at distances equal to the length of the polygon elements of the pockets, for example for pocket 81 at distances L ₁ , L ₂ , L ₃ .

The strip 64 after bending along straight lines (Fig. 12, Fig. 13) is folded into cylindrical coils (Fig. 14), connected to each other along the longitudinal edges 65 by known methods, for example by welding, into hollow straight sections 10, 11, 12, 13.

Hollow rectilinear sections, for example 10, 11, 12, 13, with pockets of a polygonal shape are rigidly connected alternately with hollow sections 6, 7, 8, 9 with pockets of a polygonal shape (figure 2) along lines 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 polygonal pockets around its inner perimeter can be made in other ways.

Vibration installation for the preparation of solutions with a square working chamber operates as follows.

The perturbing force of the vibrator 3 through the walls of the working chamber 1 is transmitted to the particles of the components of the solution and water located inside the working chamber 1. The particles of the components of the solution and water under the influence of vibration rotate in planes perpendicular to the axis of symmetry of the hollow working chamber 1 and pockets of a polygonal shape along its perimeter . The presence of pockets of a polygonal shape around the perimeter of the working chamber 1 changes the direction of motion of the particles of the components of the solutions and water, 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 movement path inside the working chamber 1, the cooking productivity is increased solutions, expanding technological capabilities.

Particles of the components of solutions and water 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 vary, then the disturbance of the movement of particles of the components of the solutions and water is aggravated, that is, there is an increase in the productivity of the preparation of solutions. The presence of polygonal helical surfaces and helical lines around the perimeter of the working chamber ensures the movement of particles of the components of solutions and water 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 particles of the components of solutions and water 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 in each section of the working chamber 1 over its entire volume, which also intensifies the process of preparing solutions and expands technological capabilities .

The technical and economic advantages of a vibrating installation for preparing solutions with a square working chamber arise due to the execution of the working chamber in the form of a square, expanding technological capabilities, increasing productivity and the path (length) of movement of particles of the components of the solutions and mixing water in the working chamber, the surface of which is equipped with unidirectional screw lines and screw surfaces, in the form of pockets of a polygonal shape, which provide a change in the direction of movement of particle flows components of solutions and mixing water and the expansion of technological capabilities.
