Description

The utility model relates to agitators and is intended for mixing liquid, semi-liquid and loose working media used and processed in the dairy and other food industries.

From the prior art, similar devices, for example, a container for the production of viscous dairy and other products (see RU 30062 U1, publ. 06/20/2003), containing a cylinder with a cooling jacket with nozzles for supplying and discharging the product and coolant, as well as a scraper device, characterized in that blades are installed on the shaft in the vessel, placed along the trajectory of a helical line, and a multi-contact scraper frame-type mixer, consisting of a frame and a scraper plate made of an elastic and elastic material, cuts of 2-4 mm in size are made along the entire length of the scraper plate , between which there are scraper elements with a step along the height of the scraper plates of 50-100 mm, while the scraper plates have the form of blades bent back and there are several scraper elements on each scraper plate, and before installing the shaft with a multi-contact scraper agitator in the cylinder, the distance along the outer edges scraper plates in the radial direction more than the inner diameter of the container cylinder by 20-30 mm, while the slots on one scraper plate are offset in height relative to the slots of the other scraper plate, and the blades, placed along the trajectory of the helix, are installed on the shaft relative to each other at a distance of 150 -250 mm, along the perimeter relative to each other by 180°, relative to the scraper plates by 90°, while the trajectory of the outer edges of the helical blades and the trajectory of the inner edges of the multi-contact scraper agitator are carried out along a radius of one value, and the width of the helical blades of the shaft is 1- 1.5 scraper width.

The proposed analogue does not provide a sufficient degree of homogenization, since the mixing devices do not provide uniform mixing.

The closest analogue of the claimed device is a spiral mixer for processing agricultural products (see CN 215311823 U, publ. 12/28/2021), which contains a stirrer body, a support mechanism for supporting the container body is located on the outside of the mixer body, the hopper is located on the tank body with agitator, and the outlet pipe is located at the lower end of the tank body with agitator. The vertical mixing unit and the transverse mixing unit are located in the mixing tank body, the drive motor for simultaneous rotation of the vertical mixing unit and the transverse mixing unit is located in the upper part of the mixer body, and the drive motor is attached to the mixer body through the fixing frame. According to the utility model, the vertical mixing unit in the vertical direction of the tank and the transverse mixing unit in the horizontal direction of the tank body are located in the tank body for mixing agricultural products, the vertical mixing unit uses spiral mixing; agricultural products can be mixed more evenly in the mixing process, and the mixing efficiency is higher.

The proposed analogue most closely matches the solution of the proposed technical problem, however, it does not solve it by the most effective method.

The claimed utility model is aimed at solving a technical problem associated with improving the quality of mixing liquid, semi-liquid and granular working media.

The technical result of the utility model is to improve the manufacturability of the device.

Achieving the set goals is possible by means of a mixing device of a paddle type with a spiral, containing a container with a lid mounted on supports, inside which the mixer shaft is placed vertically, driven by a drive located outside the container, two blade screws are placed on the mixer shaft, one of the blades of the upper screw is connected to the spiral in its upper part, and one of the blades of the lower screw is connected to the spiral in its lower part, which also has a mounting point on the shaft under the upper screw, a mixing nozzle is placed at the bottom of the shaft.

The container supports can be made adjustable.

Spiral connections are made in the form of welded bridges.

The outer diameter of the spiral is close to the inner diameter of the container.

The essence of the utility model is illustrated by drawings, in which:

fig. 1 is an image of a general view of a mixing device;

fig. 2 is a general view of a mixing device without a mixing container;

In FIG. 1-2 positions indicate the following:

1 - container for mixing;

2 - supports;

3 - agitator shaft;

4 - agitator drive;

5 - spiral;

6 - bladed propeller;

7 - nozzle for mixing;

8 - cover;

9 - suspension.

These drawings do not cover and, moreover, do not limit the entire scope of options for implementing this technical solution, but are only illustrative material of a particular case of its implementation.

In accordance with the embodiment of the utility model shown in FIG. 1, 2, a paddle-type mixing device with a spiral contains a mixing container (1), on top of which a lid (8) is placed, the lid is hinged, and a hole is made in the center of the lid to accommodate the stirrer shaft (3). The agitator shaft is driven by a drive (4) placed outside the mixing container (1) on the lid (8). The mixing container (1) is mounted on supports (2). The supports (2) are adjustable to level the position of the mixing container (1). The agitator shaft (4) is also made in such a way as to ensure its vertical placement inside the container (1). There are two bladed propellers (6) on the shaft. The blade of the upper screw (6) is connected to the spiral (5) in its upper part and with the blade of the lower screw (6) in the lower part of the spiral (5). The connection is made in the form of bridges welded to the helix (5) and propeller blades (6). The spiral (5) has another connection point to the agitator shaft (3) under the top screw (6). The connection is also made in the form of a jumper welded to the shaft and the helix. All welds are cleaned. At the bottom of the agitator shaft (3) there is a mixing nozzle (7). The outer diameter of the spiral (7) is close to the inner diameter of the mixing container (1).

All structural elements in contact with food media are made of food steel.

The mixing medium can enter the container (1) from above with the lid (8) open. Next, the lid (8) is closed, the position of the container (1) and the agitator shaft (3) is adjusted using supports (2). When the agitator shaft (3), which is communicated to it by the drive (4), rotates, the blades of the screws (6) and the spiral (5), as well as the mixing nozzle (7), come into rotation. The spiral-blade mechanism allows to stir the media completely, transferring the masses from the bottom up. The final treatment is also enhanced by the mixing shell (7).

The use of a paddle-type agitator with a spiral makes it possible to effectively mix the media proposed for processing.
