    The invention relates to a mixer for the mechanical and heat treatment of products in a liquid, pasty and / or powdered state.
    The purpose of the invention is to reduce energy consumption and increase service life.
    Figure 1 shows a rotary disc mixer with a top view; figure 2 - section aa in figure 1; on fmg.Z - mixer, longitudinal section; figure 4 - section bb in fig.Z; figure 5 is a hook-shaped stationary mixing element with a comb design of the first scraper edge; on figb - disk mixer with a wedge-shaped distribution element, as well as with an additional kneading blade on the mixing shaft, transverse section; Fig, 7 is a section bb In figb; Fig, 8 - section GGD on figb; figure 9 - scan working stepwise disk mixer.
    FIGS. 1-3 show the construction of a mixer for intermittent operation
    The cylindrical housing 1 is equipped on both sides with trade covers 2 and 3, the EI of which is fitted with the glands 4 and 5 or the caps 6 and 7, in which bearings 8 and 9 are installed. All housing parts are equipped with a heating jacket 10. The connecting pipes for heating are indicated by the positions 11 and 12. The housing is equipped with a charging port 13. A p1 loading port 14, as well as a choke 15 for removal and supply of gas. In a cylindrical and installed in most cases, the shaft 16 rotates horizontally or slightly obliquely to the housing, which rests with its necks on the bearings 8 and 9. On the shaft
    16, disc elements 17 are fixed, on which, along the outer diameter, mixing blades 18 are fixed along the axis of the shaft, forming a gap 19 with the inside surface of the housing, respectively between two planes of disc elements
    The fixed mixing elements 20 and 21 are fixed in the casing.
    Each of these mixing elements consists of a radial arm 22, which is fixed in Flange 23. A lever 24 is connected to this arm. Located along the housing wall and forming a gap 25 with it to pass the blade section 18. Lever 24 is connected to the shaft 26 directed to the shaft. cleaning the surface of the disk element. Section 25 is directed against the direction of rotation of the disk member and is able to have at least two scraper edges 27 and 2B dividing the material / ian into two streams located approximately at the right angle to each other.
    to a friend. The edge 27, which interacts with the disk element during cleaning and cleans a part of its surface, is located approximately radially to the shaft.
    Edge 28 removes residual product.
    from the surface of the disk elements. It is directed against the direction of rotation of the shaft. Section 26 is provided with a scraper 29 adjacent to the shaft, adjacent to the first scraper edge 27 and forming an angle of less than 90 ° with section 26. The surface 30 adjacent to the edge 28 of the material 30 of section 26 is inclined to the surface of the disk element to be cleaned with a hum more than
    5 90 °.
    The first scraper edge can be made comb 31 (FIG. 5) so that the strips are first removed from the surface of the product, while the second edge 32
    0 scrapes the remainder of the ring-shaped product retained on the surface of the disk member of the product.
    The first scraper edge 27 may be located farther from the surface.
    5 of the disc member than the second scraping edge 28, and therefore, at first, edge 27 removes only the upper part of the product layer, and edge 28 removes the rest of the product layer.
    0 Between the disk elements there are two stationary mixing elements 20 and 21 placed against the opposite surfaces of the disk elements. Each of the elements 20 and 21 cleans
    5, respectively, one of the opposite surfaces of adjacent disk elements.
    The mixer may be provided with a fixed distribution element 33,
    0 is wedge-shaped in cross section, tapering in the direction of rotation of the shaft, located between the disk members (Fig. B and 7),
    Element 33 is intended to5 to distribute the product along two opposite surfaces of the disk members. Due to this, product pressing can be achieved, which accelerates the kneading operation of the mixing
    0 20 and 21 elements when processing certain products.
    Figures 6 and 8 depict a T-shaped mixing element 34, which can be used to accelerate
    5, the movement of the product in the uncovered by the mixing elements 20 and 21 of the cross section between the surfaces of the disk elements.
    The mixer works as follows.
    When the shaft 16 is rotated with disk elements 17 and mixing blades 18, the product is captured by the surfaces of elements 17 and the blades 18 fixed to them and transported to the mixing elements 20 and 21.
    Scraped off elements 20 and 21 from the surfaces of the disk element and the shaft, on one side, the product is transported to the opposite surface of the disc, where it mixes with the product entrained by this surface, and on the other side is pressed by the blade 18 into the gap 25 and is subjected to high shear forces.
    The separation of the scraper into two scraping edges leads to the separation of the product into two streams, which are again mixed between the disk shells. Due to this, a good mixing effect is achieved. Additionally, this effect is enhanced by the fact that the material is transported into the gap 25 due to the inclined section 26. Along with this improvement of the mixing effect, the inclined position of the section 26 allows the product to pass into the mixing element 20 and 21 and thus prevents deposition. No specific products with a viscous structure, in the cross section between the surfaces of the disk elements.
    The invention allows a simple way to create an exchange of the product in the axial direction in a disk mixer, due to the fact that the product is transported in the axial direction by appropriately tilting the 17 blades 18 fixed to the disk elements of the blades. in periodically operating machines, due to the inclined position of the blades, there is a transporting effect on the product, and in this case the material on it is guided outside into the middle of the machine and can be mixed there with the product coming from the other side.
    Using the same principle of inclined mixing blades, which for this case have the same inclination, in other machines a continuous passage of the product from loading to unloading is achieved, and using oppositely shown mixing blades, reverse flow can be achieved.
    To conduct thermal processes, you can indicate that it is possible to implement in all disk devices a very
    large heat transfer surfaces In this case, it is usually possible not to heat all walls of the housing, but also the shaft and disk elements, and the flow of coolant or coolant is carried out using well-known mechanical sliding ring heads at the ends of the shaft (Fig. 1).
