Description

The invention relates to devices for mixing the starting components into a homogeneous mass and can be used in agriculture and other areas of the industry.

The aim of the invention is to increase the efficiency of the mixer.

Fig. 1 shows a schematic of a mixer; a cross-section j in Fig. 2 is the same, top view; Fig. 3 is a section A-A in Fig. 1.

The mixer comprises a housing 1 in which the working bodies are arranged in the form of rotating shafts 2 with plate-shaped curved elements 3 mounted on them, made of an elastic material. The elements 3 are curved in the shape of a clotoid and fixed on the shaft 2 in their middle part, while the width of the elements 3 is uniformly reduced from the middle to the ends. Element 3 is fixed on the shaft 2 at an angle to the vertical plane.

The mixer works as follows.

The original multicomponent material is loaded into the mixer body 1 through the loading port 4. When rotating horizontally arranged shafts 2 opposite to each other, the plate-like mixing elements 3, made in the form of clotoid, mounted on them in sleeves 5, produce

mixing the source material and components, together with its extension along the axes of the shafts 2. With the vibrations of the entire workplace, the material being mixed is separated through elastic spiral ends of the elements 3, forming an additional flow of the original multicomponent material in the working volume of the mixer . Elements 3, made of elastic material, make self-oscillations, which reduces the dynamic resistance when entering them into the layer of the mixed material. As a result, the elasticity of the mixing device of the proposed device and because of the heterogeneous mixing medium, low-frequency oscillations of the working body itself are formed, which significantly contributes to the reduction of energy consumption and its self-cleaning. In addition, the vibrations of the mixing body are transmitted to the mixed medium, which receives periodic additional movements directed perpendicular to the working surface

more than the hard ones, due to the oscillations of the element itself. By changing the rigid characteristics of the proposed mixing working body, it is possible to ensure an optimal technological process of displacing the medium in all respects (improvement of mixing quality, reduction of energy consumption and time: mixing, reliability in operation)

Claims (1)

The manufacture of the mixer body from the whole spring band facilitates the installation of the mixing bodies at the required angle and its stability during the operation of the mixer. Invention Formula A mixer comprising a housing in which working bodies are located in 0 five This means that the mixing process is intensified, and the use of a working body with elastic properties prevents the working body from breaking if foreign objects get into the mixed medium due to the deviation of the element in one direction or another. The use of a mixing device made of an elastic material and made in the form of a clitoid, allows to obtain torsional vibrations of the element due to its variable stiffness. At the same time, the end of the element oscillates more intensively than the beginning, which contributes to better mixing of the medium, and the installation of an elastic mixing working body in the form of clothoids at an angle to the vertical plane, moreover, promotes the movement of the mixed medium in a horizontal plane. The element with a uniform reduction of its width from the middle to the ends allows to obtain a mixing body with variable stiffness, which is necessary to increase the amplitude of the longitudinal oscillations of the rack and the torsional vibrations of the element itself, which are a monolith.
