DEVICE FOR STORAGE, TRANSPORTATION AND HEATING OF BITUMEN

The utility model relates to the field of the building materials industry, in particular to devices for storing, transporting and heating bitumen when it is delivered from oil refineries to asphalt concrete plants.

A device is known for heating and transporting polymer bituminous materials, comprising a container covered by a thermally insulated body; a heat pipe located underneath it; device for burning fuel; gas ducts; exhaust pipe; mixing body; partitions dividing the body into sections, each of which is connected to the exhaust pipe, and the heat pipe is made with windows located along the length and facing the bottom of the tank; wherein

MKI EO1S 19/08 V65D87 / 38

partitions are placed in the case between the windows perpendicular to the longitudinal axis of the flame tube, and the case is connected to the vessel along generatrixes at half its height (See USSR author's certificate No. 1609842, MKI E01C19 / 08.1990).

A disadvantage of the known device is the high material consumption of the structure due to the presence of a heat-insulating jacket, as well as low fire safety due to the presence of a complex autonomous heating system and exhaust pipe.

It is also known a device for heating, storage and transportation of materials such as bitumen, containing a thermally insulated body with a lid, supports and drain pipe; located in its lower part is a rotary working body with a drive and an electric heater and automatic heating control means, the case being made in the form of a truncated cone with cylindrical broadening in the lower part, partitions forming compartments and an overflow pipe, and the rotor in the form of a disk with ribs, axis which is located with an eccentricity relative to the axis of the housing (See USSR copyright certificate No. 1201387, MKI E01C19 / 08, 1984).

This device has high fire safety due to the lack of autonomous systems for burning fuel for heating, but has high material consumption due to the presence of a heat-insulating jacket and low reliability due to the use of rotating parts of the electric drive.

The closest technical solution to the proposed utility model is a reservoir for viscous petroleum products (see copyright certificate No. 590191, MKI V 66 D 87 / 38.1976),

containing a tank with a filler and a drain neck, a heater installed with a gap relative to the bottom of the tank, including a casing with windows and tell-tale pipes enclosed therein.

This device is impressive when you need a quick warm-up of motor oils and is unsuitable for heating bitumen. In addition, this device has a high material consumption due to the use of an additional casing with windows.

The purpose of the utility model is to reduce the time for heating bitumen during its discharge and to reduce the material consumption of the device for storing, transporting and heating bitumen.

This goal is achieved by the fact that in the device for storage, transportation and heating of bitumen, containing a tank with a filler and a drain neck and a coil for a coolant placed inside the tank, the coil is made in the form of a spatial structure forming a bottom, sides and elongated in the vertical direction from the bottom to the top of the tank is a half-loop, which includes at least 2 links of the bottom coil, which connect its two parts, and the height Nb of the sides is determined from the relation, where V is the numerical value of the volume device bones. S is the numerical value of the outer surface area of the coil and is:

The drawing shows a General view of the storage device. transportation and heating of bitumen (Fig. 1) and a coil - side view (Fig. 2); top view (Fig.Z).

Storage device. transportation and heating of bitumen consists of a tank 1, filler 2 and drain 3 necks; inputs 4 into the coil 5. made in the form of a spatial structure having sides 6, bottom 7, half loop 8, consisting of at least 2 links.

A device for storing, transporting and heating bitumen works as follows:

At the installation for the production of bitumen at a refinery, the device is filled with hot bitumen through the filler neck 2. After that, the device is transported by any type of transport (car, water, rail) to the asphalt plant. Bitumen, depending on the brand, weather conditions, and transportation distance, enters the asphalt plant in a thickened or solid state and can be stored in the device for a long time.

For unloading (discharge of bitumen), the device is installed on the unloading platform and a hot coolant (for example, industrial oil I-20 with a temperature of up to 180 C) is supplied to the coil 6 through inputs 4.

Bitumen, due to its very low thermal conductivity, is heated only in the zone of contact with the outer surface of the coil 5. and therefore, in known constructions, the process of heating bitumen from a solid (thickened) state to a fluid flow is quite lengthy.

in the proposed device, bitumen is heated in the zone of contact with the coil after the bottom of the tank 1, concluded between the bottom 7 and the sides 6 of the coil 5, a zone of bitumen preheated to a fluid state is formed. while the bulk of the bitumen in the upper part of the tank 1 remains in the solid state. The presence of half-loop 8. elongated from the bottom 7 of the coil 5 to the top of the tank 1, leads to the fact that along the walls of this floor loop formed channels of molten bitumen. Through these channels, the heated bitumen from the bottom part rises up, comes into contact with solid bitumen and heats it.

Thus, in the proposed device provides the circulation of heated bitumen in capacity. which significantly reduces the heating time of the entire volume of bitumen to a fluid state.

The calculations and experimental work showed that the most optimal, from the point of view of the size and metal consumption of the coil, is the position when the ratio of the numerical value of the outer surface area of the coil to the numerical value of the tank volume is equal to unity.

After the bitumen in the tank has warmed up to the temperature of EO-SO, it is poured (or pumped out) through the drain neck into the processing line of the asphalt concrete plant.
