Description

one

The invention is intended to heat the asphalt concrete briquettes with hot gases to produce an asphalt concrete mix with a temperature, allowing you to lay it in a hot condition in the road surface.

The known apparatus includes a firebox, a rotating drum with hollows, a chamber for charging with a chute and a discharge chamber, each of which is mounted at the end of the drum.

However, in a known installation, bitumen burns out, caused by prolonged intense heating of pieces of different mass.

In order to intensify the process of heating and eliminate bitumen burnout in the chamber of the shipment of the proposed installation, an enrichment device is placed, separated from the unloading chamber by a partition and made in the form of a prismatic grate screen, in the cavity of which the chute is placed.

FIG. 1 shows the proposed installation, a general view of the thorn chamber unloading; in fig. 2 is a section along the line A-A in FIG. one; in fig. 3 shows a section but BB in FIG. 2; in fig. 4 shows a section along BB in FIG. 2

In the installation, the drum 2 rotating on the rollers 1 is divided by a partition 3 into loading and unloading chambers. In the loading conical part of the drum, an underground grate 4, assembled from rods 5 and serving as an enrichment device, is mounted.

The charging chamber 6 with the chute 7 is adjacent to the rumble 4, which is connected to the rotating drum, while the tray is stationary.

The unloading chamber is cylindrical. To the shell of the drum from the inside are attached. Lifting buckets 8. Inside the discharge chamber enters the tray 9, fixed) 1 on the fixed

10. The partition 3 is not filled and is connected to the stove with pipes 11 and 12 and the body of the gas duct. 13, which is a continuation of the furnace 14. The nozzle 15 and the thermocouple 16 as well as the exhaust fan 17 with the gate are included in the furnace 18 and pipelines 19 and 20 connected to the chimney 21 and the firebox.

The inside of the ducts are made as follows. The furnace 14 with the flue 13 has a window and in the loading chamber. The duct 22 formed by the sheets 23 and 24 is located under the screen 4, and the sheets 23 and 25 form a vertical duct 26. The loading chamber is the duct 27 with which the duct 28 is connected in the cavity of the pipe 12 connected to the chimney 21 and the branch pipe 29.

The drum cavity is sealed with labyrinth seals 30 and swiveling aprons 31. Through compensators 32, the drum is connected to bandages 33 supported on rollers I. Briquettes are fed into the cavity of the rumble 4 through the chute 7.

Under the rumble of the gas flue 22, the flue gases come out. In the process of rotation of the drum and heating, the heated briquettes are scrambled, the components of which, failing with the rods, roll along the conical part of the drum into the unloading chamber. The flue gases from above enter through the gap between the bulkhead 3 and the drum into the discharge chamber. Heatable material

The pins 8 are fed into the discharge chamber in the flue gas stream descending into the inlet 28.

Subject invention

A plant for processing asphalt briquettes with hot gases, which includes a furnace, a rotating drum with blades, a chute loading chamber and a discharge chamber, each of which is mounted at the end of the drum, characterized in that, in order to intensify the process of heating and eliminate bitumen burnout, An enrichment device is placed in the loading chamber, which is separated from the unloading chamber by a partition and made in the form of a prismatic grate screen, in the cavity of which the chute is placed.
