Abstract

FIELD: mixing materials. SUBSTANCE: mixer has the mixing chamber. The hose connected with the systems for supplying and discharging working agent is mounted inside the chamber. The working member made up as a torus is mounted on the hose. The working member reciprocates inside the chamber under the action of the working agent which is supplied and discharged from the hose. In so doing, two mixing zones with one mixing member exist. EFFECT: improved design. 1 dwg

Description

 The invention relates to a mixing technique and can be used for mixing liquid, solid, gaseous components, as well as their combinations.

A device for producing paint suspensions, containing a vacuum pump and mixer with a mixer moving reciprocating along the shaft, as well as a system for supplying components and removing the finished mixture [1]
Disadvantages: high energy costs for the supply of components and the drive of the mixer, providing rotational and translational movement, the complexity of the design.

The prototype of the invention is a pneumatic mixer containing a housing with an aerodynamic and working body, affecting the intensity of the supply and mixing of components, as well as a screw system for feeding components and pneumatic discharge of the mixture [2]
The disadvantages of the prototype: high energy consumption for the supply of components and their mixing, low productivity due to the low throughput of the mixing zone.

 The technical effect of the invention is to reduce energy consumption and increase the productivity of mixers.

 This effect is achieved by the fact that in a mixer containing a mixing chamber with a working body, connected to the supply and discharge systems of the working agent, the component supply and discharge systems of the mixed substance, according to the invention, a sleeve is arranged along the chamber axis communicating with the supply and removal systems at the ends working agent, the working body is made in the form of a torus mounted movably on the sleeve.

 The working body performs the function of a mixing body moving reciprocating through the chamber with the help of a working agent, alternately supplied and withdrawn from the ends of the sleeve.

 At the same time, displacement to the extreme position during the supply of components facilitates this process by creating a certain vacuum in the chamber.

 In addition, the supply of components on both sides of the torus forms two mixing zones with one working body, which increases the performance of the mixer.

 The drawing schematically shows a mixer in cross section.

 The mixer contains a mixing chamber 1, in communication with systems 2, 3, 4 of the supply of components and the system 5 of the removal of the finished mixture. A sleeve 6 is coaxially and concentrically placed in the chamber 1, the opposite ends of which are fixed at the ends on the nozzles of the working agent supply and exhaust systems 7, 8. On the sleeve 6 mounted torus 9, which is a working body.

 The mixer operates as follows.

 By system 8, a working agent is fed into sleeve 6, and system 7 is withdrawn from sleeve 6. In this case, torus 9 shifts to the left, i.e. to that end of the chamber 1, on which the system 7 of the supply and removal of the working agent is located. A certain rarefaction is created in the chamber 1, due to which the components of the mixture are supplied by systems 2, 3, 4. Then, the working agent system 7 feeds into the sleeve 6, and system 8 removes the working agent from the sleeve 6. The torus 9 is shifted to the right end of the chamber 1, creating excessive pressure for the previously supplied components, and in the vacated zone there is some depression, and portions of the mixed components are also fed into this zone by systems 2, 3, 4.

 Then, by alternately feeding into the sleeve 6 and withdrawing the working agent from the sleeve 6, a predetermined number of movements of the torus 9 along the chamber 1 is provided, which determines the preparation of the finished mixture. The torus 9 alternately displaces the finished mixture by overpressure into system 5. The action of systems 2, 3, 4 (supply of components) and 5 (removal of the mixture), 7, 8 (supply and removal of the working agent) is ensured by the presence and operation of the valve system. Then the cycle repeats.

 The mechanism of movement of the torus 9 is due to the fact that an empty sleeve 6 is passed through it, therefore, when a working agent is fed into the sleeve 6, it increases in diameter, and the torus 9 is forced to slide towards the smaller diameter of the sleeve 6.

 The use of the proposed mixer reduces energy consumption for the supply of components, their mixing and removal, increases productivity due to the work of two mixing zones with one mixing body.
