Description

The invention of mercury is related to road construction and the procuring of building materials, in particular, to devices for preparing bitumen.

A device for melting bitumen is known, including a heat-insulated container with an opening, a vertical melting chamber with vibrators, electric heaters and a bottom plate ij moving in the opening.

A disadvantage of this device is the duration of the bitumen smelting process and the lack of devices dp to maintain the required temperature of the molten bitumen, which reduces the efficiency of its use in production.

The closest to the proposed device is a bitumen melting device, which includes a heat-insulated container with an opening blocked by a lid, a melting chamber with thermoelements located above the bottom of the container at least two electric heaters and a bitumen pump with a primary device and an iJ internal-circulation pipeline.

However, the known device is characterized by an insufficient heat transfer intensity in the melting chamber, an uneven distribution of electric heaters over the area of the bottom of the tank and the lack of heating of the bituminous pump, which reduces the heating efficiency and performance especially when the bitumen is frozen in the tank.

The purpose of the invention is to increase efficiency.

The goal is achieved by the fact that in a device for melting bitumen, including a heat-insulated container with a cross-sectional opening, a melting chamber with a thermoelement w located above the bottom of the tank, at least two electric heaters and a bitumen pump with a spray device and a pipe-mounting device. The melting chamber is equipped with a casing fixed in the opening of the container and mounted on the latter by vibrations, the thermoelements of the melting chamber formed in the form of two intersecting rods oshch Skog resistance disposed zigzag-shaped and curved, forming the walls and the grating D1shsche chamber, heaters in each tier raspolozheshd in Playa petleoS AZNO and intake pump prisposoblesh1e bitumnygo taken loops between the top tier has zlektronagrevateley.

FIG. 1 shows schematically the proposed device, a general view, a section, FIG. 2 is a section A-A in FIG. one; in fig. 3 is a view B in FIG. one.

5 A device for smelting bitumen. It has a thermally insulated container 1 with an opening 2. At the bottom of the container 1, two isolators of electric heaters 4 are installed on the insulators 3, each made, for example, of reinforcing steel bars looped in plan: In the opening 2, thermally insulated capacitive 1 is mounted on shock absorbers 5 protective cover

5 fusion chambers with a lid 7. In the casing 6, two insulator 8 rods 9 (electrical heaters), made, for example, of reinforcing steel, are connected to each other by insulators 8, which are connected at one end to each other, and the power supply ends.

Each bar 9 has a zig zags in a 1x, cross-hinged, figuratively curved planes that form the walls and a lattice bottom of the chamber. Insulators 10 are placed between the rods 9 of the bottom of the melting section 6. Vibrators 11 are installed on the side walls of the casing 6.

On top of the tank 1, there is mounted a cloud pump 12 with a suction device, a joint 13, located between

5 loops of the upper russia of the electric heaters 4, the end product outlet nozzles 14 and the internal circulation pipeline 15, the end of which is directed to the wall of the chamber;

0 laziness.

The device works as follows.

Lump bitumen is loaded into the melting chamber formed by the rod 9, after which the lid 7 of the protective casing 6 is closed, and both electrons of the heater 4 and the rods 9 are connected to the mains. To accelerate the separation of the liquid phase of the depleted bitumen from the solid, vibrators 11 are turned on, and the molten bitumen starts to drain into the heat-insulated container 1, in the case of the working temperature of the molten bitumen is maintained by the electric heater 4. With

In order to accelerate the melting of lump bitumen from the control panel to drive the bitumen pump 12 to the Irrigation position and melt or bitumen through the intake subassembly O1e 13, the pump 12 and pipeline 15 fall on the non-melted pieces of bitumen located in the melting chamber. The delivery of the finished bitumen is carried out by switching the three-way valve (not shown) to the position

Extraction and bitumen is delivered to the consumer through nozzle 14,

After completion of the work, the electricity is cut off and the melting chamber is cleaned of the remaining wrapping paper and other inclusions. The lower location of the heaters 4 above the bottom of the tank facilitates the rapid heating of the total volume of tank 1 and the bitumen pump 12, which allows for a short period of time to turn on Irrigation, by which the melting time is reduced.

The location of the boring device 13 between the loops of the upper russia and heated 4 ensures reliable operation of the bituminous pump 12

The melting chamber provides direct contact of the rods 9

lump bitumen, and the operation of the vibrator 11 makes it possible to immediately separate the liquid phase of the bitumen from the solid, which shortens the melting time of the lump bitumen that is in the melting chamber.

Heaters made of reinforcing steel ensure the operation of the device during

lifetime and replace them with. , the construction site does not cause difficulties in connection with the lack of reinforcing steel. Primeieii ark {aturnoy steel instead of round

allows, at the same power consumption, to increase the heater surface by 1.3 times, which shortens the melting time of bitumen due to inteysification 1: (and heat transfer.
