Abstract

The invention relates to the construction, namely to devices for melting bitumen. The purpose of the invention is to provide ease of use when heating bitumen briquettes in a package. In a bitumen smelter, the device for placing a briquette is made in the form of a lattice having longitudinally arranged horizontal ribs. Inside the chamber there is a device for removing the packaging with a drive for its vertical movement. The device for removing packaging is made in the form of scrapers fixed on its case and mounted one above the other with a gap on the shafts parallel to the plane of the grid, driven and driven drums. On the drive drum mounted recessed discs located in the grooves of the driven drum. The drive drum shaft is kinematically connected to the carriage. After the end of the melting process, the scrapers pick up the package with drive and driven drums. The packaging is compressed between the drums and placed on the cart. 4 il.

Description

The invention relates to the construction, namely to devices for melting bitumen.

The goal is to provide ease of operation when heating bitumen briquettes in a package.

FIG. shows the installation, general view; on (2g. - section aa on .1; in fig. 3 - section bb in fig. 2; fig, 4 - node i in fig. 2.

The installation for melting bitumen contains a heat-insulated chamber 1, in the lower part of which a storage tank 2 is located, and in the upper part in the openings of the screens 3 air recirculation fans 4 are installed. Between the inner surface of the chamber 1 and the screens 3 are horizontally fixed side steam registers 5 and electric motors 6, forming a thermal cavity with openings at the top under the fans 4 and at the bottom under the heaters 5, 6 to create a movement of the air-cooled heat carrier. Below the storage tank 2 are lower steam registers 75 which are intended to maintain the temperature of the molten bitumen in the storage tank 2-. The camera has a loading window with a sash 8 and a lifting mechanism 9.

In front of the loading window, an overpass 10 is installed, according to which, with the help of an electromechanical actuator 11, a device for placing a briquette - a cart

ka 12 s bopta da, the base of which is made with a prololny horizontal retrac 13 located evenly at intervals. On the basis of the carriage 12, bitumen coils 14 are located.

The installation is equipped with a device 15 for removing the package, containing a housing 16, on which the scrapers 17 and 18 are rigidly fixed with a gap of shu longitudinal ribs 13 and above and mounted one above the other with a gap on shafts parallel to the plane of the grating driven 19 and slave 20 drums. On the drive drum 19 are mounted with 21 wheels located in the grooves of the driven drum 20.

Depending on the dimensions of the working chamber, one or two drive drums 19, respectively, are installed on one or two shafts 22, according to its width. mounted in the housing 16. At the outer cantilever end of the shaft 22 extending beyond the dimensions of the carriage 12, an asterisk 23 is installed, cooperating in the lowest position of the device 15 for removing the package during the return stroke of the carriage 12 with the rail 24, which is placed horizontally on the bracket 25 fixed on the outer plane of the longitudinal side of the truck 12.

The removal device 1 5 is installed above the loading window of the camera 1 with the possibility of vertical movement down to the base of the trolley 1 2 using block systems and a drive mechanism 26 mounted on the camera 1-. To do this, rollers 27 are mounted at the ends of the shafts 22, which, when lowering and raising, slide along guide rails 28 vertically mounted inside chamber 1. The installation is equipped with instrumentation 29. To remove steam and gas generated during the melting of bitumen, The installation is equipped with adjustable {th dampers (not shown) with air duct 30. Rails 31 are laid along the top of racking drive rack 10, psha passage into chamber 1.

The bitumen smelter works as follows.

From freight transport, unpacked bitumen packs from 14 bitumen are unloaded onto an overpass. 10

and take it on rails 31 in camera i. Sash 8 boot window close. Then, heaters-electric heaters 6 are turned on together with steam registers 5 and 7 and at the same time the air recirculation fans 4 are turned on. The air circulating in the working chamber 1 is heated to the operating melting temperature of the bitumen (180-210 C5 not exceeding the temperature of the brewing. The monitoring is carried out by the instrumentation 29. The gas-circulating coolant, in contact with the surface of the bitumen bay 14, melts it, and melted through the base of the lattice the bitumen mass flows into storage tank 2, which is constantly heated from below by lower steam registers 7, as a result of which the bitumen is maintained in the finished molten state.

As the bitumen coils 14 melt, the package settles onto the base of the carriage 12.

After the smelting process is completed, the electric calories 6 and the bot steam registers 5 and the fans 4 are disconnected. 28 Fixture 15 is removed to remove the packaging from lateral displacements, which ensures that the position of the scrapers 17 and 1 8 corresponds to the position of the longitudinal ribs 13 of the base of the cart 12 and the slots between them. The scrapers 17 are located in close proximity to the outer surface of the ribs 13, and the scrapers 18 are lowered into the grooves between the ribs. In this case, the sprocket 23 engages with the rail 24, Then the electromechanical drive 11 of the return stroke of the carriage 12 is turned on, the rail 24. Through the sprocket 23, the driving drum 19 is rotated by the gripping disks 21. The scrapers 17 and 18 pick up the package and direct it to the exciting discs 21, which sweep it further between the drive 19 and the slave 20 drums. The package is passed between the drums and pressed. In this case, excess liquid bitumen is squeezed out of the package and flows into the collection tank 2. The package is placed on the working surface of the carriage 12 in the form of a compressed tape. After the carriage 12 and the chamber 1 have come out, the device 15 for removing the packaging with the aid of the drive mechanism 26 along the direction of the head 28 rises to an upper position above the loading window. Compressed packaging is easily removed from the cart. The delivery of molten bitumen is produced as necessary through a drain pipe (not shown), and the gases and vapors formed during the smelting process are removed through adjustable dampers into the air duct 30.
