(54) BITUMEN TREATMENT BOILER

I

The invention relates to the field of road construction and the building industry, namely to devices for the heating and dewatering of bitumen.

The bitumen boiler is known for its continuous operation. auth. St. 242217, comprising a housing with bottoms and a lid, a firebox, a charging tank for evaporation of bitumen, vertically installed flue pipes, gas passages, a settling tank for bitumen, and a chimney l.

The disadvantage of this boiler is the slow melting of lump bitumen in loading tanks and the insufficiently high heat output from the mountains of gas in gas-filled cavities.

The aim of the invention is to intensify the bitumen smelting process.

This goal is achieved by the fact that the cube is additionally equipped with flue pipes with nozzles and two partitions, one of which is V-shaped and bent in the gaower cavity from the rear end of the boiler, and the second is at the bottom of its front end.

horizontally installed in loading tanks and connected by nozzles with corresponding vertical pipes.

This embodiment of the boiler provides a change in the Sequence of the connection of its cavities and flame tubes with the direction of the gas flow from the furnace to the first; a queue under the loading tanks and additional heat supply to the melted bitumen through horizontally installed heat pipes, which speeds up the process of melting and dewatering the bitumen.

FIG. 1 shows the proposed boiler, longitudinal section; in fig. 2 - section A-A of FIG. one; in fig. 3 - section bb FIG. one,

The bitumen boiler has a body 1, a lid 2 with a settling tank 3, a bottom 4, a reservoir 5 for evaporation, a firebox 6, loading tanks 7 forming with a lid 2 and a metal casing with a heat insulating layer 8 of the cavity 9 for the passage of a stream of hot gas, vertical flame tubes 10, horizontal flame tubes 11 with branch pipes connected to tubes 10 and exhaust tube 12, cavity 13 of the pepper-

the front part of the boiler, side cavities

14, cavity 15 under the bottom. In the rear end of the boiler cavity, a partition 16 is installed in a V-shaped curved wall, which forms a cavity 17 and 18. The cover 2 in the rear end has an opening 19 for the passage of hot gas from the cavity 7 in the cavity 9, and in the front end part of the opening 20 for the passage of the mountains of

gas from the cavities 9 into the cavity 13.

The bottom 4 at the rear end of the boiler has openings 21 for the passage of a stream of hot gas from the cavities 14 and 18 into the cavity

15, and a second partition 22 is installed at the front end of the boiler. The finished bitumen is discharged from tank 5 by crane 23. The tank has connected ducts 24 adjacent to horizontal pipes 11.

The piece of bitumen, which is located in the loading containers 7, is heated to a flowing state with a heat stream of hot gas coming from the furnace 6 through the cavity 17 and the holes 19 in the cavity 9. As the melt melts, the bitumen from the tanks 7 is poured into the sump 3j where more than the yellow impurities are deposited and the light is poured; into the tank 5 for evaporation. The flow of hot gas. passes through holes 20 along Cavity 13 and 14, then through holes 21 into cavity 15 and through vertical heat pipes 1O, which heat the bitumen in the reservoir 5. The piece bitumen in the charge tanks 7 replenishes with the heat of the hot gas stream, passing through the horizontal zhag) Ochgm pipes 11. Gas and water vapors. TS from evaporation tank 5 through ducts 24 to pipes 11,

connected to the chimney 12.

Such a constructive solution allows one to create a higher temperature head in the cavities under the load tanks and to intensify the process

melting lumpy bitumen in charging tanks, which will increase labor productivity.
