Description

I

The invention is primarily used in the oil and fat industry and is referred to as a vaporizer vaporizer for meal.

The closest to the invention of the technical essence and the achievable effect of the known is a canned evaporator for meal consisting of a vertical case, tubs with steam jackets, bypass holes, chutes and valves, each of which contains a shaft and mounted on there is a damper for overlapping the chute, a central hollow shaft carrying the agitators, formed by inclined plates and horizontal scrapers fixed at their ends, steam supply systems to the chano shirts and a hollow shaft and piping that is common with the shaft cavity for inlet of steam into the body of the Ci.

However, in such a device, the dampers and the stirrer plates that are in contact with the meal are not heated, vapors condense on their surfaces and sticking of the meal occurs. Poured meal acts as a sponge for solvent vapor and moisture and, in addition, the condensate partially flows into the material being processed. All this reduces the efficiency of solvent stripping.

The chain of the invention is an increase in the efficiency of distillation.

To achieve the goal, the valves of the valves and the plates of the mixers are hollow, the partitions with openings are located in the cavities, the shirts of the tanks communicating with the cavities of the dampers, and the pipelines for injecting steam into the body are connected to the cavity of the shaft through the posts of the agitators. Each valve shaft is advisable to LIPPY hollow at the ends, with the jacket of each vat communicating with the cavity by a corresponding valve through one of the cavities led, and the other cavity will serve for condensate from here.

FIG. 1 shows a general view of the evaporator; in fig. 2 — node I in FIG. 1 | in fig. 3 - section A-A of FIG. 2 in FIG. 4; section BB; FIG. one; in fig. 5 shows a section bb of FIG. four; on figo b - type G fng-, 5,

The evaporator consists of a heated housing 1, which is installed in it

vats 2 with steam jackets 3 and a centrifugal hollow shaft 4 carrying coaxial stirrers, each of which is formed by an inclined plate 5 and attached to the end of the last horizontal scraper 6. The plates 5 are mounted on a suspension 4 with holders. Their cavities 8 are divided by partitions 9 with openings Ю, forming labyrinth channels for the passage of steam, and communicate with cavity 11 of shaft 4 through pipes 12 and 13. Pipelines 13 are installed on scrapers 6 with brackets 14.

The bottoms of the tanks 2 are made with bypass holes 15 and chutes 16. In the brackets of each chute, a shaft 17 is installed, at the ends of which there are cavities 18 and 19. A valve 20 is welded to the shaft, in cavity 21 of which ribs 22 with holes 23 are installed. also form a labyrinth channel for steam. The cavity 21 communicates with the jacket 3 of the corresponding tank through the pipe 24, the cavity 18 and the hole 25, and the drain 26 serves as a hole 26, the cavity 19 and the pipe 27 The pipe 24 is connected to the jacket of the tank through the coupling 28 and pipe 29.

A rod 30 is welded to the valve 20 on which the load 31 is fixed, fixed by nut 32, and a level regulator 33 fixed by nut 34. i The evaporator works as follows.

The meal arriving in it enters sequentially from one vat 2 to another through openings 15, stirring with stirrers, warming up and steaming with hot steam. A layer of material in each tank is supported by a counterweight valve 31. As this layer increases, the material, acting on the level 33 regulator, presses the valve 20 against the chute 16, blocking the bypass hole 15. When the layer of material under the valve is reduced, the valve opens, allowing the material in the next vat. The valve and the plates of the agitators are heated with steam, the steam entering the jackets 3 of the vats 2 through the pipes 29, the couplings 28, the pipes 24 entering the cavities 18 of the shafts 17, from where through the holes 25 it passes through the cavities 2 of the valves 20, moves along the labyrinth channel and condenses ; the condensate is removed through the holes 26, the cavity 19 and the pipes 27. The steam entering the cavity 11 of the shaft 4 passes through the pipelines 12 in the cavity 8 of the plates 5 and, after passing through the labyrinth channel, enters the pipelines 13, from where it is injected into the housing 1.

Thus, the gasoline distillation process is intensified.
