Abstract

The utility model relates to devices for mixing materials and can be used in construction, mining, food, medical and other industries. The utility model is aimed at creating a device for mixing materials with high efficiency of its operation by organizing selective loading of the source material and unloading the finished product. This is achieved by the fact that the device for mixing materials contains a spherical mixing chamber with a hatch. The camera is placed on the carrier and rotates by means of rotation gears. The carrier rests on the racks, one of which has a latch. The hatch is made in the form of a box, on the inner opposite walls of which a slide is fixed with the possibility of moving the plate along them. The plate can be solid or mesh.

Description

The utility model relates to devices for mixing materials and can be used in construction, mining, food, medical and other industries.

Known device for mixing materials [Yudin KA, Degtyar AN, Kharin NP. Simulation of bi-directional rotational action on material in a spherical mixing chamber. Vestnik BGTU im. V.G. Shukhov. 2017. No 5. S. 126-132], containing a mixing chamber of a spherical shape with a hatch, rotated by means of a bevel gear and two chain drives placed on the carrier, racks on which the carrier is fixed. On one of the struts there is a latch with the possibility of its longitudinal movement until it contacts the carrier.

The disadvantage of this device is the low efficiency of mixing materials due to the accumulation of material under the hatch at the time of loading.

Known device for mixing materials, which is a prototype [RF patent for utility model No. 193687, Appl. 07/30/2019, publ. 11/12/19, bul. No. 32]. The device for mixing materials contains a mixing chamber of a spherical shape with a hatch, rotated by means of a bevel gear and two chain drives (rotation transmission) placed on the carrier, and racks on which the carrier and the retainer are fixed, and a rotation drive with a gear that rotates the carrier around the horizontal axis and a mixing chamber about a second mutually perpendicular axis. A diffusion cone is fixed in the mixing chamber opposite the hatch.

The following set of prototype features coincides with the essential features of the utility model: a spherical mixing chamber with a hatch, placed on the carrier and rotated by means of rotation gears, and racks on which the carrier and the retainer are fixed.

The disadvantage is the low efficiency of mixing materials, due to the presence of inhomogeneous particles of the loaded and unloaded material, due to the lack of their classification.

The utility model is aimed at increasing the efficiency of mixing materials by organizing selective loading and unloading of material.

This is achieved by the fact that the device for mixing materials contains a spherical mixing chamber with a hatch. The camera is placed on the carrier and rotates by means of rotation gears. The carrier rests on racks, one of which has a latch. The hatch is made in the form of a box, on the inner opposite walls of which a slide is fixed with the possibility of moving the plate along them. The plate can be solid or mesh.

The utility model is illustrated by a drawing, where FIG. 1 shows a device for mixing material with a solid plate, and FIG. 2 - hatch with a mesh plate.

The device consists of a mixing chamber 1 of a spherical shape with a hatch 2. Mixing chamber 1 is fixed on the carrier 3. The carrier is equipped with rotation gears 4. The carrier 3 is fixed on the racks 5. On one of the racks 5 there is a lock 6.

The hatch 2 is rigidly fixed, for example, by bolts, to a spherical chamber. The hatch is made in the form of a rectangular box 7. On the inner opposite walls of the box are fixed, for example, by welding, slide 8 with the ability to move along them solid 9 or mesh 10 plate. The mesh plate 10 has the required mesh size. The plates are installed in the box through the hole 11. On the right side of the box 7 there is a stopper 12 with the possibility of fixing with the plate.

The device works as follows. When fixing the carrier 3, the starting material, for example, components of dry mixtures (cement, sand, chalk), is fed through the open hatch 2 into the mixing chamber 1.

For the selectivity of the feed material, it is necessary to install a mesh plate 10 with the required mesh size. The materials entering the chamber 2 under the action of gravity rush vertically downward and are distributed under the entrance hatch 2. It is assumed that the material will fill the spherical mixing chamber by one third of the volume. The hatch 2 is closed with a solid 9 plate and the working cycle begins. The rotation of the carrier is carried out by means of rotation gears. The torque generated by the engine rotates the carrier 3 with the mixing chamber 1 at high angular speeds. The realized bi-directional rotational action on the material leads to an increase in the intensity of mixing of the particles.

Bidirectional rotational action on the material occurs in two mutually perpendicular directions. On the one hand, centrifugal forces are due to the rotation of the carrier 3 with the mixing chamber 1 fixed on it relative to the horizontal axis. On the other hand, centrifugal forces are due to the rotation of the mixing chamber 1 itself about an axis mutually perpendicular to the horizontal axis. The superposition of forces forces material particles to move along a complex trajectory.

The cycle time will vary depending on the material being loaded.

When the power supply is cut off (not shown in the figure), the carrier 3 with the mixing chamber 1 stops and is fixed with a latch 6. To achieve the selectivity of unloading the material, squeeze the stopper 12 and pull out the solid plate 9. Then install the mesh plate 10. The mesh plate 10 is fixed with the stopper 12 and the material is unloaded.

The possibility of using 10 mesh plates with the required mesh size will allow organizing selective loading and unloading of material. In addition, the use of mesh plates will limit the yield of unmixed particles (accumulations of particles), i.e. carry out the classification.

The proposed solution will ensure the selectivity of loading and unloading material, which will lead to an increase in efficiency when mixing the material in the mixer as a whole.
