Abstract

The utility model relates to the field of general engineering, in particular to devices for mixing materials with poor flowability and differing in density, for example, for mixing prescription components of animal and plant origin of microbial synthesis products in animal husbandry.

The technical result that can be achieved using the proposed utility model is to intensify the mixing process and the universalization of the mixer.

The mixer contains a housing 1, loading 2 and unloading 3 holes on which a motor 4 is mounted with a V-belt transmission 5. Inside the housing 1 on the shaft 6, a mixing device is fixed in the form of pairwise standing blades 7 and destroyers 8, while the destroyer 8 is made in the form of a rod which has a constant zone of deformation of the mixture, regardless of the angle of rotation of the blade 7, with the possibility of regulating the distance between the destroyer 8 and the blade 7 selected depending on the physicomechanical properties of the components of the mixture. Adjusting the distance between the destroyer 8 and the blade 7 and the angle of rotation of the blade 7 makes it possible to obtain optimal mixing quality and improve the performance of the mixer.

Description

The utility model relates to the field of general engineering, in particular to devices for mixing materials with poor flowability and varying in density, for example, for mixing prescription components of animal and vegetable origin, as well as microbial synthesis products in animal husbandry.

The prior art.

A known mixer containing a support frame, a housing with loading and unloading holes, a shaft with blades made of central and peripheral plates mounted on brackets in intersecting planes (see Germany patent No. 1557223, Cl. 12 e 4/01 published. 12.02. 71).

The disadvantage of this mixer is the imbalance of the moving flows of the mixture, resulting in a difference in pressure on the left and right end walls of the mixer. This reduces the intensity of the mixing process.

Known paddle mixer, comprising a support frame, a housing with loading and unloading holes, a shaft with blades in the form of a wedge or ploughshare with a rod base

(see copyright certificate Japan No. 62-31605, MKI ⁷ 01 F 7/00, 7/04 published. 07/09/1987).

The disadvantage of this mixer is the inability to control the intensity of mixing of the mixture due to a change in the angle of the blade to the direction of its movement. When the angle of setting of such wedge blades to the direction of movement when mixing inhomogeneous components changes, the drag area of one of the wings of the blade increases sharply and the mixture begins to condense, which reduces the mobility of particles and leads to uneven distribution of components in the mixture.

The closest in technical essence and the achieved positive effect, and adopted by the authors for the prototype, is a paddle mixer, including a support frame, a housing with loading and unloading holes, a shaft with blades consisting of central and peripheral plates (see USSR author's certificate No. 778762, Cl ³ B 01 F 7/04 published 15.11.1980).

The disadvantage of this mixer is the sticking of the particles of the mixture on the surface of the plates with increasing speed of rotation of the blades.

Disclosure of the invention.

The technical result that can be achieved using the proposed utility model is to intensify, that is, accelerate the mixing process and universalize the mixer to mix the most physically-mechanical properties of the components of the mixture.

The technical result is achieved in that in a material mixer comprising a housing with loading and unloading openings, a mixing device in the form of blades and disruptors facing them, mounted on the housing with a V-belt drive electric motor, the destroyer is made in the form of a rod, which has a constant mixture deformation zone regardless of the angle of rotation of the blade, with the ability to control the distance between the destroyer and the blade selected depending on the physicomechanical properties of the component mixture.

The implementation of the invention.

The mixer contains a housing 1, with loading 2 and unloading 3 holes on which an electric motor 4 with V-belt drive 5 is mounted. Inside the housing 1, in the grooves of the shaft 6, a mixing device is fixed in the form of pairwise standing blades 7 and destroyers 8, the destroyer 8 is made in the form of a rod , which has a constant zone of deformation of the mixture regardless of the angle of rotation of the blade 7, with the possibility of regulating the distance between the destroyer 8 and the blade 7 selected depending on the physico-mechanical properties of the components of the mixture.

The material mixer operates as follows.

Inside the housing 1, through the loading hole 2, the mixture components are loaded and the electric motor 4 is turned on, which transmits the rotation through the V-belt drive 5 to the shaft 6. When the shaft 6 is rotated, the mixed material is first loosened by the destroyer 8, and then under the action of the blade 7 set at an angle that affects productivity, not only mixed, but also sent to the discharge hole 3, which ensures the best miscibility of the components of the mixture. Under the action of the destroyer 8, located in front of the blade 7 at a distance selected depending on the physicomechanical properties of the components of the mixture and controlled by moving the destroyer 8 in the groove of the shaft 6, the portion of material has a smaller

bulk density, which makes it possible to obtain optimal mixing quality.

Setting the rod 8 of circular cross section in front of the blade 7 will destroy the core of the seal and get the area behind the rod 8 with a lower bulk density, in which mixing will occur in a pseudo-liquefied state, with no plastic deformation.

The invention in comparison with the prototype and other known technical solutions has the following advantages:

- universality;

- increase in productivity;

- improving the quality of mixing the components of the mixture;

- ease of implementation;
