Abstract

The invention relates to devices for mixing and dispersing liquids and can be used for mixing and dispersing multicomponent materials, for example, in the preparation of foam materials. The purpose of the invention is to reduce the clogging of the device and improve the quality of the material obtained. For this, the mixer-sprayer is equipped with through valves, and the rotary elements 11 of the shut-off valves are made with coaxial inlet channels 12 by outlet channels 13, while the through-valves are installed in the outlet channels 13 of the stop valves 14 behind the inlets of the output channels 14. Solid inclusions, coming along the lines together with the liquid components of the material, by inertia pass into the drainage channels 13 and. accumulate in them behind the inlets of the output channels 14, which reduces the possibility of clogging the radial channels of the mixing chamber 2 and the spray nozzle. 2 Il. i (L s

The invention relates to mixing and spraying apparatus and can be used for blending and spraying multicomponent materials, for example, by foaming foam materials.

The aim of the invention is to reduce the clogging of the device and the quality of the material obtained,

Figs, shows the mixer-sprayer |. in Fig about 2 - section aa in Fig.1

The mixer-sprayer with derchchit case 15 is made in it the mixing chamber 2, lines 3 and 4 of the separate supply of the components of the material, - W: - S S compressed air supply and expanding, nozzle 6,

Radial 9 and tangential 10 channels arranged in one plane and adjacent to each other by outlet outlets 7 and 8 are made in the casing to enter respectively material and air components into the mixing chamber 2

The sprayer has shut-off Kpaitbi in the form of rotary elements r I with a shade to 3 and 4 of the supply of material components by the inlet 12, bypass I3 and by the perpendicular outlet 14 channels,

Rotary elements 11 are installed in lines 3 and 4 for supplying material components with the possibility of combining output channels 14 with inlet openings of radial channels 9. The spreader is equipped with through valves 15 and 16p installed in branch ducts 13 of shut-off valves behind the inlets of output channels 14. In L-5 supply of compressed air: an adjusting screw is installed; screw 17. A screw 18 is connected to case i; a cer 18 with a tap 19 for a solvent sub pod; a solvent into the mixing chamber 2. The mixer-discharger 1 operates as follows.

The liquid components of the maternap are supplied via lines 3 and 4 to Ehodia channels 14 of shut-off valves And to; through; combined channels 14 and 9 are fed to; mixing chamber 2. Scooped air is fed through line 5 and through taken-: Diagonal channels 10 BBOAK-I CH in dare--: a camera chamber 2,

; In the mixing chamber 2, the mixing of the swirling-shm- flow-: | {OM of the airborne components of the germinal to

the resulting mixture of material components is sprayed through the nozzle 6.

Solid inclusions coming along lines 3 and 4 together with liquid no. 1 components of the material; by inertia pass into the diversion channels 13 and accumulate in them behind the inlet openings of the output channels 14, which reduces

j the possibility of clogging of the radial channels 7, the mixing chamber 2 and the spray nozzle 6. With the accumulation of solid particles in the exhaust channels 13 open passage valves 15

5 and 16 and under the pressure of the material, solid particles are brought out.

The mixer-tapper allows TaKjKB to clean the radial; -IL; X channels 9 To do this, instead of the spray gun, 6 are installed on the hooks and under air pressure, with the taps 15 and 16 open,

When the solvent is supplied through the cer 18 units, the mixture is mixed with the spray chamber chamber 2 and the spray nozzle} 6,

The present spray mixer allows pre-heating of the housing 1 before mixing and expansion of the material components. For this, the through valves 15 and 16 communicate with the supply containers (shown) and produce a circus. the cultivation of thermostatically controlled components of materials, i

The use of the invention makes it possible to increase the productivity of the mixture of i-body solids by reducing retraction charges and to improve the quality of the multicomponent material obtained.
