Изобретение относитс к нефтехимическому машиностроению и может быть использовано при эмульгировании расво- ров полимеров, например а производстве искусственных латексов.The invention relates to petrochemical engineering and can be used in the emulsification of polymer solvents, for example, in the manufacture of artificial latexes.

Известные устройства дл эмульгировани имеют пилиндрический корпус с входными и выходными патрубками, ста- торные и рюжорыый диски с коаксиапьно расположенными вендами зубьев. Диски образуют последовательно соединенные пр мой центробежный и обратный каналыThe known devices for emulsification have a pilindrical housing with inlet and outlet connections, stationary and neat disks with coaxially arranged weights of the teeth. The disks form a series-connected direct centrifugal and reverse channels.

Moreover, the separation of the heavy phase occurs both from the forward centrifugal flow and from the return flow directed from the periphery to the center.

The material being processed is moved from the center to the periphery.

В этом устройстве, так же, как и в упом нутых устройствах, эмульси под действием инерционных сил раздел етс на более т желую малоконцентрированную эмульсию и периферии аппарата и более легкую высококонцентрированную эмульсию, наход щуюс ближе к центру аппарата. Неоднородность полученной эмульсии снижает качество продукта, увеличивает количество отходов производства при даль-. нейшей обработке из-за недостаточной устойчивости эмульсии.In this device, as in the aforementioned devices, the emulsion under the action of inertial forces separates into a heavier, less concentrated emulsion and the periphery of the apparatus and a lighter, highly concentrated emulsion, which is closer to the center of the apparatus. The heterogeneity of the resulting emulsion reduces the quality of the product, increases the amount of waste in the long-. treatment due to insufficient emulsion stability.

Claims

The purpose of the invention is to intensify the mixing process by creating a circulation of the solution. 36 This is achieved by the fact that the inner station body is equipped with a classifier made in the form of a truncated cone, fixed with a smaller base on a stator disk installed on the material outlet, while in the stator disk placed on the material inlet radial channels communicating with the axial peripheral holes . The drawing shows a proposed device for emulsifying solutions in water. The device has a cylindrical body 1 with covers 2 and 3, input 4 and output 5 nozzles and a shaft 6 connected to a drive (not shown). In case 1 there are stator disks 7 and 8, fitted with teeth 9 and 10, placed in a concentric environment The bridge is installed at the entrance, and the disk 8 - at the outlet of the material. The inner walls of the housing 1 are equipped with an emulsion classifier 11, made in the form of a truncated cone fixed to a smaller base on the stator disk 8. The disk “7 contains peripheral, axial holes a located at the housing 1, and radial channels b connecting the peripheral part of the device from the central. Holes and channels b are interconnected. Between the stator augers 7 and 8 on the shaft 6 is mounted a rotor disk 12 having teeth 13 and 14 arranged coaxially to teeth 9 and 10 of the stator disks 7 and 8. Disks 7 and 8 and 12 form channels in and g. The device operates as follows. A mixture of the polymer solution and the flow of water into the nozzle 4. Under the action of the rotating disk 12, the material enters the channel and emulsifies when it passes between the fixed 9 and 13 rotating teeth. O-1 pulses with a higher density (with a lower content of the hydrocarbon phase) are thrown to the periphery, to the classifier 11. Here, the heavier phase is shifted towards the larger diameter of the classifier 11, to the hole a, and then enters the radial channel B. The emulsion is returned to the channel to re-emulsify with the new material. At classifier 11, emulsifiers with meager density (with a high content of hydrocarbon phase) are displaced towards a smaller diameter of classifier 11. To carry out the check emulsification emulsion, if necessary, is fed into channel g, where it is freed from emulsion residues with a higher density directed to 11. A stable emulsion, ready for further processing, is discharged from the device through nozzle 5, and the separated emulsion of greater density, as indicated above, is returned through apertures a and channel b re-processing. Apparatus of the Invention A device for emulsifying solutions in water, comprising a cylindrical body with inlet and outlet nozzles, stator disks provided with teeth arranged in concentric circles, and installed one at the exit and the other, made with peripheral axial holes, at the material inlet, and a rotor disk mounted on the shaft between the stator disks, having teeth arranged coaxially to the teeth of the stators, characterized in that, in order to intensify the mixing process by creating a circus The inner walls of the housing are equipped with a classifier made in the form of a truncated cone, fixed by a menor on the stator disk mounted on the material outlet, while in the stator disk placed on the material inlet radial channels communicating with the axial peripheral holes.
