Abstract

Mixture preparation plant comprising a loading hopper with a metering device, a housing with an impeller, a hollow screw, a suction and discharge nozzles, a hollow screw at one end fixed to the impeller, a loading hopper installed perpendicular to the suction nozzle and a hollow screw, the suction nozzle is fixed at the opposite end hollow auger, characterized in that the opposite end of the hollow auger is fixed in the bearing, with mechanical seals installed on both sides of the bearing.

Description

The utility model relates to installations for the preparation of mixtures and can be used in lines for preparing liquid substitutes for whole milk from dried powder, suspensions, as well as in lines for preparing, for example, ice cream.

A known installation for the production of reconstituted milk, comprising a device for supplying powdered milk powder and water, a cylindrical mixer with a drive shaft with blades coaxially located therein and a device for draining reconstituted milk [1].

The disadvantage of this installation is that due to the formation of lumps of milk powder and air ingress, productivity is reduced.

Known mixers for mixing liquid media with powder masses, containing a loading chamber with a valve, a centrifugal pump, a paddle mixer [2, 3]. In these devices, a dry (bulk) component supply scheme is used, which is characterized by such a drawback as a powder product hangs and the impossibility of its transportation to the working chamber.

The closest in technical essence and the achieved result is a device containing a loading chamber, a housing with a suction and discharge nozzles, with the impeller and auger located in it [4].

The disadvantage of this device is that during operation, due to the cantilever attachment of the screw, a runout occurs causing distortion and, as a result, depressurization of the connection between the screw and the suction pipe. Air entering the impeller entails a reduction in productivity and a deterioration in product quality due to foaming.

The technical result is to prevent air from entering the impeller through leaks at the junction of the screw and the suction pipe, and as a result, the finished product with improved quality is ensured.

The technical result is achieved by installing one end of the hollow screw in the bearing, with mechanical seals installed on both sides, which exclude the runout of the end portion of the hollow screw.

This technical solution allows, due to the rigid fastening of the screw, to ensure the operation of mechanical seals in the normal mode. The result is a technical result, which consists in eliminating the ingress of air through leaks at the junction of the screw and the suction pipe.

The mixture preparation plant comprises a feed hopper, a housing with an impeller, a hollow auger, suction and discharge nozzles, a hollow auger, one end of a hollow auger fixed to the impeller, and the opposite end of the hollow auger fixed to the bearing.

This utility model is illustrated in the drawing.

In FIG. 1 schematically shows an apparatus for preparing mixtures.

The installation consists of a loading hopper 4, the housing 7, the suction 1 and the discharge pipe 5, the impeller 8 and the hollow screw 9.

The hollow screw 9 is fixed in a bearing 2, on both sides of which mechanical seals 10 are located, which prevent liquid from entering the housing where the material is moved by spiral winding of the hollow screw 9

In the lower part of the loading hopper 4, located perpendicular to the suction pipe 1 and the hollow screw 9, there is a device 3 that provides a metered supply of material.

Installation works as follows. The liquid enters the center of the impeller through the suction pipe 1, through the hollow auger 9, then into the impeller 8, and loose or powdery components, when opening the device 3, from the hopper 4 under the influence of gravity is fed to the hollow auger 9, and enters into the impeller 8. The components are pre-mixed on the open part of the wheel, then, when interacting with the stationary blades 6 and further in the annular outlet, the final mixing of the components takes place. The formed homogeneous mixture is discharged from the housing 7 through the discharge pipe 5.

The design of the proposed installation will prevent air from entering the impeller through leaks at the junction of the screw and the suction pipe.
