Description

one

The invention relates to devices for the treatment of liquids and can be used in the chemical and petrochemical industries, and more specifically in the processes of mixing and drying of liquid powders.

A known apparatus for treating a viscous liquid, comprising a housing with a heat-exchanging jacket, perforated disks mounted along the height of the housing, pipes for supplying and withdrawing a product, and pipes for supplying and withdrawing a coolant 11

The disadvantage of this apparatus is the lack of mixing of the product, which reduces the efficiency of processing, for example drying.

The closest to the proposed technical essence and the achieved effect is an apparatus for processing viscous liquids, comprising a housing concentrically mounted in the housing with the possibility of reciprocating movement

ALONG the longitudinal axis of the latter from the vibrating conductor, a shaft with perforated mixing elements fixed on it along its length, alternating with fixed perforated mixing elements fixed on the body along the RHL, and check valves 2J,

The disadvantage of the apparatus is that the heat exchange surface is only the upper boundary of the viscous liquid, which reduces the processing efficiency of the material, in particular, the efficiency of its drying.

The purpose of the invention is to increase the processing efficiency.

This goal is achieved in that the apparatus comprising a housing concentrically mounted in the housing with the possibility of reciprocating

The 20th displacement along the longitudinal axis of the latter from the vibrating conductor is a shaft with perforated mixing elements fixed on it along its length, alternating with fixed perforated mixing elements fixed to the housing along its height, and check valves equipped with control valves mounted on the housing for drying: agent, stationary mixing elements are made in the form of hollow fixed disks, with connections for the inlet and outlet of the coolant and tubes connecting the holes erforatsii upper and lower surface of the fixed disks, and check valves are mounted on the bottom of the movable mixing elements, FIG. 1 schematically shows the proposed apparatus; in fig. 2 - ra cut AA on FIG. one; on fig.Z - section bb in fig. one; in fig. 4 shows a section B-B in FIG. 2; in FIG. 5 is a section of YYD in FIG. 3. The apparatus comprises a housing consisting of several sections 1 with stationary mixing elements fixed on the case along its height, made in form-perforated fixed disks 2. In the case there is a shaft 3 mounted concentrically with movable mixing elements fixed on it along its length , made in the form of perforated disks kf alternating with fixed disks 2. The shaft 3 is mounted with the possibility of reciprocating movement along the longitudinal axis of the housing from the vibrating drive (in the drawing it turned out). The casing has also a pipe 5 for evacuating vapor, a pipe 6 for introducing viscous liquids, distribution valves 7 for introducing a drying agent, check valves 8 mounted on the lower of the disks k, and a pipe 9 for draining the viscous liquid. Hollow fixed disks 2 have nozzles 10 for input and output, heat transfer fluid, tubes 11, connecting holes on the upper and lower surfaces of fixed disks 2 and partition walls 12. Holes 13 of perforated disks are formed by bends 14, 15. The device works as follows. A viscous fluid, such as liquid rubber, is fed into the apparatus through pipe 6 and moves through the tubes 11 of the fixed disks 2 and the holes 13 of the disks k from top to bottom. Through the distribution valves 7, the drying agent is introduced and moves in the housing from the bottom up. In the cavity of the discs 2, coolant is supplied through the nozzles 10, bends around the partition wall 12 and is removed from the discs 2. The shaft 3 and the discs 4 are reciprocated from the vibrodrive, as which electromagnetic or eccentric mechanisms can be used. The small frequency of oscillations of the disks 4 (0.1-1.0 Hz) provides the conditions for countercurrent movement of the phases, since at a low frequency of the oscillations the inertial forces are lower than the force of gravity, as a result of which the gas continuously moves upwards. The viscous fluid passing through the body is mixed and dried. Gas distribution over the cross section of the apparatus and dispersion mixing is carried out using bends 14 and 15 on the disks 4. The check valves 8 installed on the lower of the disks 4 periodically create a zone of increased pressure in the gap between the lower disk 4 and the bottom of the apparatus, which provides ejection of viscous fluid from the apparatus through the pipe 9. The drying agent is discharged through the pipe 5. The distribution valves 7 at the time of the approaching the lower disk 4 and the lower fixed disk 2, when the pressure in the gap between them increases, slamming which prevents the penetration of a viscous liquid into the supply system of the drying agent. The proposed design of the apparatus makes it possible to carry out an efficient treatment in a thin liquid, including stirring, heating and drying, to reduce the energy consumption for mixing the liquid and to increase the speed of the drying process by 5-7 times. The invention The apparatus for processing viscous liquids, comprising a housing concentrically mounted in the housing with the possibility of returning translational movement along the longitudinal axis of the latter from the vibratory drive, a shaft with perforated mixing elements mounted on it along its length alternating with those fixed on the housing along its height fixed perforated displacement elements, and check valves characterized in that. in order to increase the processing efficiency, it is equipped with control valves mounted on the housing for the drying agent, fixed mixing elements are made.
