Utility Model Implementation

The vertical dispersant-reducer consists of the following main parts: cover 1, chamber 2, housing 3, base 4, wheel 5, impeller 6, stator 7, rotor 10, shaft 11, double mechanical seal 13, o-rings 14-18, table 8 with adjustable supports, funnels 9, damper straight 19, electric motor 20.

The electric motor 20 is installed together with the base 4 on the table 8 and is fixed. The shaft 11 of the dispersing unit is mounted on the shaft of the electric motor 20. On the housing 3 with a sealing ring 17, a chamber 2 with a discharge pipe 21 with a diameter of 50 mm is installed. To prevent leakage of working fluids, chamber 2 is equipped with a double bellows mechanical seal 13 (for example, the company "JOHN CRANE" brand 0400 / Т2100 / S / AR1C1 / М). Seals 13 water cooling; water is supplied through the bottom 24 and leaves the chamber through the top 23 fittings (G1 / 2 ”). A rotor 10 and an impeller 6 are mounted on the shaft 11 of the dispersant assembly. A stator 7 is mounted on the chamber 2 with a sealing ring 17. A wheel 5 is mounted on the shaft 11 of the dispersing assembly and the entire package (pos. 4, 6 and 5) is tightened with nut 12. For O-rings 14 and 15 are installed to prevent product from entering the keyed connection. The chamber 2 with the o-ring 17 is fixed to the stator 7 using three studs 21 with nuts. In the chamber 2 there is a branch pipe with a diameter of 50 mm, through which the unit is connected to the working capacity or product supply line. A lid 1 is mounted on the chamber 2 with the sealing ring 16, having a nozzle with a diameter of 80 mm for loading powder (dry milk products). A straight valve with a funnel 9 is installed on a branch pipe with a diameter of 80 mm.

Fundamentally, the dispersant-reducing agent device consists of three mixing sections.

The first section is formed by a cover 1 and a chamber 2, equipped with nozzles for loading powder and liquid (water). In the diffuser pipe, the liquid and dry ingredients are fed separately until they reach the blades of the wheel 5.

The second mixing section is a high-speed mixer and is formed by the stator housing 7 and the wheel 5. In the second section, the mixing (dissolution) process begins. Water and powder are thrown away by the blades of the wheel to the walls of the housing, where they change direction and move from the bottom of the washer to the central hole. Next, the product is picked up by the impeller blades 6 and sent to the rotor blades of the dispersing wheel.

The third mixing section consists of an impeller 6, a rotor 10 and a stator 7. The working bodies of the dispersant are the rotor 10 and the stator 7, on which three rows of teeth are made. The gear elements of the rotor 10 and stator 7 are placed on alternating concentric circles. When the rotor rotates, the product is forced through centrifugal force through periodically aligned and overlapping channels of the rotor 10 and stator 7.

The product is processed due to the following forms of exposure: the interaction of particles with the fluid flow and with each other, impact with rotating and stationary elements of the rotor 10 and stator 7.

The geometric dimensions of the channels, their number, their location relative to each other in combination with the rotor speed and the resulting centrifugal forces create conditions for a direct hydraulic shock in an unsteady flowing fluid, which contributes to the amplification of acoustic vibrations in the sealed rotor cavities, the gap between the rotor and stator and sound camera. In addition, with such organization of the product flow, cavitation processes are intensified, i.e. there is a gap in the continuity of the product into many separate streams and the formation of cavities or cavitation bubbles filled with a mixture of gas and steam in it. Therefore, after such processing, the product takes the form of a homogeneous highly dispersed emulsion.

All parts in contact with the product are made of steel that is approved for contact with food products of the Ministry of Health of the Russian Federation (for example, steel grade 12X18H10T).

Thus, as a result of the implementation of the claimed device provides an increase in the efficiency of technological processes of dispersion and emulsification of substances in liquid phases.

A comparative analysis of the claimed utility model showed that the set of essential features of the claimed device is not known from the prior art and therefore corresponds to the patentability condition “Novelty”.

The above information confirms the possibility of using the claimed device for mixing, mixing, dissolving, dispersing, emulsifying substances in liquid phases, and therefore meets the patentability condition "Industrial Applicability".
