Abstract

FIELD: chemical industry; food industry. SUBSTANCE: mixer has case, mixing chamber provided with blade stirring tool and mechanism of tool's drive, and branches for feeding components to be mixed and removing ready mixture. The case is provided with elastic hose, one end of which is attached to the case along its perimeter. The other end of the hose is connected with additional branch pipe, inside which curved perforated partition and blade stirring tool are mounted. Drive mechanism of stirring tool is made in form of two drive reversible drums, which are mounted inside the case and connected with stirring tool by flexible link. The case communicates with branches for feeding and removing working substance. When feeding working substance, stirring tool is shifted along the mixing chamber, and components are mixed pneumatically. Blade rotor is driven into rotation by reversible drive, as well as components, which are mixed mechanically. EFFECT: high quality of mixture; exclusion of forming stagnation areas. 1 dwg

Description

 The invention relates to mixing equipment and can be used in chemical, food, pharmaceutical and other industries, including when mixing clumping or viscous materials.

A device for producing paint suspension, containing a vacuum pump and a mixer with a mixer moving reciprocating along the shaft, as well as a system for supplying components and removal of the finished mixture [1]
The disadvantages of the device are as follows: high energy consumption for the supply of components and the drive of the mixer, which performs both rotational and translational movement, design complexity.

A known fluid mixer containing a mixing chamber, nozzles for introducing components and outputting the finished mixture and a paddle mixing mechanism, driven by the energy of the jet of supplied liquid [2]
The mixer has the following high energy consumption for the supply of components and the drive of the mixer, the inability to mix liquids with solid components.

 The purpose of the invention is to improve the quality of mixing and reduce energy consumption for the supply of components and drive the working body.

 This is achieved by the fact that in the mixer, including the housing, the mixing chamber, in communication with the nozzles for feeding the mixed components and the outlet of the finished mixture and containing a paddle mixing body with a drive mechanism, the housing is equipped with an elastic sleeve fixed to it along the perimeter, the other end of which is connected with an additional nozzle in which a curved perforated partition and a paddle mixing organ are installed, the drive mechanism of which is made in the form of two drive reversible drums, installed in the housing and connected to the mixing body by a flexible rod, while the housing is in communication with nozzles for supplying and discharging a working agent (compressed air).

 By supplying compressed air to the sleeve, the pipe with the working body is moved along the mixing chamber and at the same time it is bubbled through the holes in the partition into the mixing zone. By reversing the rotation of the drive drums in mutually opposite directions, the rotor rotor is rotated by a flexible traction, providing mechanical mixing by the blades. Compressed air entering through the openings in the baffle cleans the blades from the sticking of components.

 The drawing shows the proposed device, General view.

 The mixer has a housing 1, in communication with a pipe 2 for supplying compressed air (working body) and a pipe 3 for exhaust air. The housing 1 is connected by an elastic sleeve 4 with an additional nozzle 5 equipped with a curved perforated partition 6. In the nozzle 5 there is a rotor 7 with blades 8. The rotor 7 is equipped with a pulley 9, covered by a flexible rod (s) 10, wound on reversible drive drums 11, 12. Holes 13 are made in the partition 6. The sleeve 4 with the working body installed in the nozzle 5 is placed in the mixing chamber 14, in communication with the nozzle 15 for feeding the mixed components and with the nozzle 16 for withdrawing the finished mixture.

 The device operates as follows.

 The components are fed through the nozzle 15 to the mixing chamber 14, the working agent (compressed air) is fed through the nozzle 2 through the sleeve 4 into the mixing chamber. The sleeve 4 under the action of compressed air moves the additional pipe 6 with the rotor 7 along the chamber 14 to a distance set by the flexible rod 10. The air entering through the openings 13 pneumatically mix the components. Its excess is discharged through the pipe 3. The drive drums 11, 12 are reversed, rotating the pulley 9 and the rotor 7 with the blades 9 reversely with a flexible thrust and providing mechanical mixing of the mixture. After mixing the components with a flexible rod 10, the rotary working element and sleeve 4 are retracted, and the sleeve 4 is moved along the chamber 14 by the action of compressed air and the finished mixture is forced out into the nozzle 16. Then the operation cycle is repeated.

 The use of the invention provides high quality mixing due to the combination of mechanical and pneumatic mixing, eliminates the formation of stagnant zones, reduces energy consumption for the supply of components.
