Description

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

There are known installations for mixing liquid media with powder masses, containing a loading chamber with a valve, a centrifugal pump, and a paddle mixer [1,2].

The disadvantage is that these devices use a dry (loose) component supply scheme, which is characterized by such a disadvantage as freezing of the powder product and the impossibility of transporting it to the working chamber.

The closest in technical essence is a device containing a loading chamber with a damper, a housing with suction and discharge pipes, an impeller with inter-blade channels formed by the blades, main and covering disks of smaller diameter than the blades, and blades mounted on the side wall of the housing around the covering disk [3].

The disadvantage of this device is that during operation, the dosing device located for supplying dry components from the loading chamber operates due to manual adjustment, and as a result, if the product hangs, it is not possible to supply it to the feeding device and then to the working chamber for mixing. Thus, the feeding device is not an active working body, which leads to inaccurate dosing and arching at the entrance to the feeding device and, as a consequence, a decrease in the productivity of the installation.

The technical result consists in simplifying the design, increasing the dosing accuracy and eliminating the entry of air into the chamber for transporting the dry component.

This goal is achieved by installing a dosing device with cells in the lower part of the loading hopper in the form of a gear wheel that engages with the spiral winding of a hollow screw. Accordingly, the feeding device drives the cell metering device, which will move the material from the feed hopper. Installing a dosing device with cells in this way allows for more accurate dosing of the dry component, and prevents the entry of air, and also prevents the spontaneous outflow of the dry component when the feeding device is stopped. The design of the device in the form of a gear wheel simplifies the operation of the installation and facilitates the dosing process, namely the flow of the dry component onto a hollow screw with spiral winding.

The installation for preparing mixtures contains a loading hopper, a housing with an impeller, a hollow screw with a spiral winding, suction and discharge pipes, a hollow screw with a spiral winding, one end is fixed in the impeller, and its opposite end is fixed in a bearing.

This invention is illustrated by the drawing.

In fig. 1 schematically shows an installation for preparing mixtures. The installation consists of a suction pipe 1, a bearing 2, a dosing device with 3 cells, a loading hopper 4, a discharge pipe 5, fixed blades 6, a housing 7, an impeller 8, a hollow screw 9, mechanical seals 10 and an annular outlet 11.

A hollow screw with a spiral winding 9, one end is fixed in the impeller 8, and its opposite end is fixed in a bearing 2, on both sides of which there are end seals 10, which prevent the lubricant from entering the housing 7, where the material moves using the spiral winding of the hollow screw 9. In the lower part of the loading hopper 4, perpendicular to the suction pipe 1 and the hollow screw with spiral winding 9, there is a dosing device with cells 3, which is engaged with the spiral winding of the hollow screw 9; this design solution ensures a dosed supply of powdery material. The dosing device 3 is a gear with cells for capturing and moving the powdery component from the loading hopper 4 onto the spiral winding of the hollow screw 9.

The installation works as follows. The liquid enters the center of the impeller through the suction pipe 1, through a hollow screw with spiral winding 9, then into the impeller 8, and dry or powdery components under the influence of gravity from the loading hopper 4 enter the dosing device with cells 3, which rotates behind due to engagement with the spiral winding of the hollow screw 9, as a result of this, the dry and powdery component, due to the spiral winding on the hollow screw 9, enters the impeller 8. The components are pre-mixed on the open part of the wheel, and then when interacting with the stationary blades 6 and further into In the annular outlet 11 the final mixing of the components occurs. The resulting homogeneous mixture is discharged from housing 7 through discharge pipe 5. The design of the proposed installation will prevent air from entering the impeller through leaks in the area of the hollow screw and suction pipe.

The use of the proposed installation for the preparation of liquid feed mixtures will allow for high-quality and quick mixing of dry feed components with liquid, and through the use of an active dosing device with cells, a stable supply of dry components will be ensured, which will increase the dosing accuracy and, as a result, the accurate supply of the component to the working mixing chamber, which increases the productivity of the installation and the quality of the finished product.
