The advantage of the squeegee according to the invention is that, with a simple structure, it has high efficiency and the ability to control and read parameters. A rotor with two blade discs prevents loads from axial forces. The possibility of opening and closing the flaps of the suction chambers makes it possible to regulate the flow of extracted gases. The squeegee of the rotor according to the invention is schematically illustrated in the drawing in which Fig. 1 shows the squeegee in a front view with a partial axial vertical section, Fig. 2 - the squeegee in a side view, Fig. 3 - the squeegee in a top view. The suction head has a spiral casing 1, and inside it, on the shaft 2, a rotor 3 is mounted, which consists of two discs 4. Both discs 4 are mounted on the shaft 2 inside the spiral casing 1. There are twenty blades 5 for each disc 4. 5 is slightly arched along its length and twisted in its axis at the end. In the upper part of the spiral casing 1, two suction chambers 6 are mounted on both its outer sides, each of which has at least two flaps 7 at the entrance, and all flaps 7 are connected by a system of cables 8 connected to the mechanism 9 for opening and closing the flaps 7 and a hand pump 10 for their lubrication. The shaft 2 on the outer side of the helical casing 1 is mounted in slide bearings 11 and through a clutch 12 driven by an electric motor 13 mounted in bearings 14. A brake 15 with a hand wheel 16 is mounted on the plate of one slide bearing 11. lubrication with oil from lines 17 of the hydraulic system 18 connected to the control and measurement controller 19, and additional protection of lubrication from the drop tank 20. The mechanism 9 for opening and closing the flaps is also connected to the control and measurement controller 19. The electric motor 13 is cooled by air, which passes through two water coolers 21. The spiral casing 1 consists of three segments 22 joined together, and an outlet 23 is attached to the lower segment 22. After actuation by the control 19 of the electric motor 13, the shaft 2 is activated, which drives the rotor 3 with blades 5. The rotating rotor 3 creates a vacuum which sucks gases through the suction chambers 6 and discharges them through the outlet 23 to the chimney. The opening and closing of the dampers 7 is automatically regulated by the mechanism 9 by the control and measurement controller, and the manual pump 10 lubricates the tie rod system 8. The precisely defined temperature and pressure of the oil supply to the bearings 11 and 14 is monitored and controlled by the control and measurement controller 19, to which is also connected the bearing vibration sensor 11 and 14. The manual knob 16 causes the clamping of the brake shoes 15 in the event of an emergency braking of the rotor 3.
