Equipment for washing a carpet includes a conveyor for transferring the carpet between washing and drying units, a control unit, at least one washing unit and at least one drying unit located in the transport direction after the washing unit, and elements for receiving production goods to the equipment. The conveyor is able to transfer the carpet through the washing and drying units with the same speed. The washing unit includes a wet or dry cleaning unit, with at least one brush and elements for transferring the carpet. Each drying unit has a blowing device for blowing compressed air at a pressure of 2-15 bars onto the pile side of the carpet, the blowing pressure depending on the carpet type and/or transfer speed of the carpet at a drying station of the drying unit, it being possible to blow such an amount of compressed air through the drying apparatus so that the carpet exits the drying station tack free. |

1. Equipment for washing a carpet (M), the equipment comprising:
a vehicle with a motor (1010); a machine unit (100) within the vehicle, the machine unit (100) including an hydraulic pump (15) and an electric motor, the motor of the vehicle being connected to the hydraulic pump (15) to generate electricity, as well as pressure and volume flow for hydraulic liquid; an equipment frame (10) integrated into the vehicle; a conveyor (3), a washing unit (4), and a drying unit (2) carried by the frame (10), the conveyor (3) comprising an endless belt (32) extending from a first feeding end (10a) of the frame to a second discharge end (10b) of the frame, the frame having a planar surface extending from the first feed end (10a) to the second discharge end (10b), the washing unit (4) comprising a wash basin (40), in use the wash basin holding water having a water surface (V1) that is located below the planar surface between the first feed end (10a) to the second discharge end (10b), the washing unit further comprising, inside the wash basin, i) a brush (41) that is located below the water surface (V1) and ii) means for transporting the carpet out of the wash basin, the drying unit (2) comprising i) a drying station (21) located downstream of a exit of the wash basin (40), and ii) drying unit (20) located above and directed toward the drying station (21), wherein the drying unit (2) has an air blowing device (20) comprised of an air knife (20) making use of venturi and coanda phenomena to blow compressed air from an exit of the air knife onto the carpet located on the drying station (21), the compressed air being a parallel laminar air jet of compressed air directed towards the drying station (21) and exiting the air knife (20) at a blowing pressure of 2-15 bars onto a pile side of the carpet (M); wherein the conveyor (3) transfers the carpet (M), in a transport direction (K), directly from the washing unit (4) to the drying station (21) of the drying unit (2) with a ply side of the carpet facing the exit of the air knife; a control unit (5) that controls operation of the conveyor (3), the washing unit (4), and the drying unit (2) so that the conveyor (3) transfers the carpet (M) through the washing and drying units (4, 2) at the same speed, wherein the control unit (5) controls the blowing pressure depending on i) the carpet type and ii) transfer speed of the carpet at the drying station (21) of the drying unit (2) and blowing such an amount of compressed air onto the carpet through said drying apparatus that the carpet exits the drying station (21) tack free, the underside of the carpet being sufficiently air proof that the air flow blown onto the carpet bounces substantially back from the carpet underside, wherein the drying unit thereby provides a rinsing stage by the air jet blowing water away from the carpet's pile, the air blowing pressure of the air jet being adjusted by adjusting a distance between the exit of the air knife and the carpet in the drying station such that a thickness and a volume flow of the air jet is a function of the distance between the carpet in the drying station (21) and the exit of the air knife (20) and when more air is to be fed onto the carpet moving through the drying station, the exit of the air knife is taken farther away from the carpet's surface, and when less air is to be fed onto the carpet moving through the drying station, the exit of the air knife is brought closer to the carpet surface, wherein the equipment is self-sufficient in relation to production goods such that all operating energy for powering the conveyor (3), the washing unit (4), and the drying unit (2), and heating energy (400) for water used in the washing unit (4) is provided exclusively from the motor (1010) of the vehicle, and wherein said equipment is free of any rinsing stage other than said drying unit (2). |
