Abstract

The invention relates to devices for cleaning airfield runways from snow, ice, moisture, dust. The purpose of the invention is to increase efficiency by reducing the energy intensity of the cleaning. The device contains a box-shaped casing 1 and a housing in the center of the space below it, the walls of which form a closed channel in which the gas flow guides 3 are placed, the gas generator 4: about a driven stream and heating elements placed in front of the generator 4 discharge pipe. housing mounted infrared generator. In the working and transport positions, the housing rests on the wheels and is moved with a slacker energy carrier. Garbage, moisture from melting snow and ice are collected in niches and trays. 2 hp f-ly, 4 ill. e (L

This invention relates to maiganes for cleaning airfields in winter.

The purpose of the invention is to increase efficiency by reducing the energy intensity of the cleaning process.

Fig. 1 shows a device for cleaning airfield pavements, top view of Fig. 2, section AA. in fig. one; FIG. 3 is a section BB in FIG. one; figure 4 - section bb in fig.Z.

A device for cleaning airfield pavements contains a box-shaped casing 1 which is open from the bottom, a housing 2 fixed in the casing, the walls of which are closed. The case is mounted in the central part of the casing. At the side walls of the casing, curved guides 3 of the gas flow and a generator 4 of the gas flow are fixed, implemented, for example, in a high-pressure fan or a compressor blade. In front of the generator 4, a heat exchanger with heating elements 5 is installed, and on the suction nozzle side there is a protective grid 6. For collecting large inclusions transported by the flow of heat, pallets 7 and 8 are located in the corner parts of the casing. The casing rests on wheels 9 fixed on it by means of brackets 10. The wheels are raised or lowered by drives 11. The connecting elements 12 connect the device with the energy carrier — a wiper (not shown).

Inside the housing 2, an infrared emitter 13 is mounted, attached to the casing by means of suspensions 14o. In front of the generator 4 and under the pressure wheel, it is made by picks 15 and 16, intended respectively for collecting large soils and water. From the layers, water is pumped by pump 17 to tank 18. To seal the space under the casing, apron 19 is fixed along its perimeter, and in front of the apron, compaction rollers 20, which interact with the aprons, are attached to the casing at the front and rear. Rollers

20 includes elastic tires

21 low pressure, discs 22, elastic inserts 23 seals.

 Rollers are attached to the casing by means of hangers 24. Niche doors 25 are provided for access to the pallets (figure 2).

The device works as follows.

When the gas flow generator 4 is switched on, the gas flow in the direction along the channel formed by the casing 1, the housing 2 and the airfield pavement. . arrow G. When the gas flow moves, it sweeps away the garbage and stones that are deposited on the pallets 7 and 8, held by grids 6. Garbage and stones catchers work on the principle of changing the direction of the gas flow and. Mounted in all four corner niches of the device. Before entering the gas flow into the gas flow generator, a grid 6 and a tray are installed to hold light fractions of garbage and stones. The gas flow generator is driven by a drive, for example, in the form of an electric motor. If necessary, the treatment of the surface covered with ice, include a heat exchanger, embodied, for example, in the form of heating elements 5, of the type, and, if necessary, infrared emitters 13. In this case, the moisture from this ice is trapped by hot gas flow and taken out of it by the impeller wheel of the gas flow generator 4 due to centrifugal forces c. The water flowing down falls into the tank 16, from where pump 17 collects into the tank 18. The apron 1 has an apron 1 around the perimeter of the building's economy. 9, complete in the form of a rubber apron. A similar seal is made along the outer perimeter of the casing and in the transverse direction reinforced by rollers 20 installed in the transverse direction of the device. Front and rear for the entire length of the suspension on the 24 o. the disks 22, and from the ends, identical identical protrusions. The gaps between the rollers 20 are sealed with elastic inserts 23. When the roller rushes with an elastic tire on a solid obstacle, the latter is installed in the roller, causing it to rise and form a gap between it and aerodrome coating. In the event of a solid obstacle in the area of the disk 22, the roller rises
