The present invention relates to a laundry machine, comprising: a tub (120) for receiving wash water; a drum (130) rotatably provided in the tub (120); an air supply device (160) provided at an upper part of the tub (120) for heating air discharged from the tub (120) and introducing the heated air into the tub (120); and a cooling water supply device (300) to supply cooling water to a rear inner surface of the tub (120) such that the rear inner surface of the tub (120) forms a condensing surface to generate condensed water.
Abstract:
There is described is a belt cleaning blow-off device having a streamlined inner surface. In one embodiment a fluid outlet nozzle is connectable to a conduit of a blow-off device for cleaning a belt filter. The nozzle comprises a housing having an inner surface and outer surface, wherein the inner surface defines a fluid entry zone to receive fluid into the nozzle and an elongated gap for directing fluid towards the belt. The inner surface is streamlined to facilitate flow of the fluid into the gap. In a second embodiment, the blow-off device comprises a housing connectable to a fluid source and having an inner and outer surface. The housing defines a conduit for transporting the fluid within a channel, wherein the inner surface defines a surface of the channel and an elongated gap for directing the fluid towards the belt. The inner surface is streamlined and typically teardrop-shaped to facilitate flow of the fluid into the gap.
Abstract:
A filter apparatus includes a filter, such as a cartridge, positioned within a housing. The filter apparatus has multiple ports and valves, so as to allow a user to easily switch between a filtration mode of filtering fluids and a maintenance mode of cleaning the filter. The filter can have a filter substrate in a housing and after filtrate builds up on the substrate, the substrate can be cleaned by directing a spray of fluid, such as from a ring of nozzles at the top of the housing, onto the substrate. A maintenance port can be provided to drain the debris washed from the substrate. The filter can switch between a backwash mode and a filtration mode.
Abstract:
A laundry treating machine is provided. The laundry treating machine may include a tub to receive wash water, a drum rotatably provided in the tub, an air supply device to supply air to the tub, a lint filter to filter lint from the air circulated by the air supply device, a filter cleaning device to supply cleaning water to the lint filter to remove the lint from the lint filter, and a cooling water supply device to supply cooling water to an inner surface of the tub such that moisture contained in air is condensed at the inner surface of the tub.
Abstract:
A seal is brought into contact with a filter media, a filter pump is operated to start filtration, and a signal from a pressure sensor is received. When a predetermined value is exceeded by the signal from the pressure sensor, the filter pump is stopped, the seal is separated from the filter media, and take-up of one section of the filter by a filter collection roll is started. In finishing filter supply from a filter supply roll, drive of a motor is stopped, and an alarm signal is transmitted. If the supply is not to be finished, one section of the filter is taken up by the filter collection roll, and the next stage of filtration is entered.
Abstract:
The invention relates to a method for washing a filter (F) having at least two layers of filtering media (4, 5) for raw water containing components having a tendency to form cakes (M), in particular for seawater, the layers of filtering media being supported by a base (6) comprising pass-through openings and provided with nozzles (6a) enabling air and/or wash water to be injected, the raw water flowing through the layers from top to bottom and the treated water being recovered at the lower portion of the filter, and which comprises at least one spillway (D) at the upper portion thereof for collecting the wash water. The method includes the following series of steps: a) the raw water intake (2) is closed, followed by the filtration outlet valve (13), the filter is depressurized, and the filter cake is broken; b) the water level in the filter is lowered; c) only pressurized air is blown into the lower portion of the filter, said air passing through the layers of the filter from bottom to top and causing the cakes to be reduced to particles, in particular by means of friction; d) rinsing is carried out from bottom to top using only water, the water rinsing time being sufficiently short to ensure that the water level stops below the level of the upper edge of the wash water collection spillway; e) the filter water is emptied once again by discharging same from the lower portion of the filter; f) steps c), d) and e) are repeated at least once, and a final rinsing is carried out by injecting a quantity of backwashing water through the bottom portion of the filter, which is then discharged from the upper portion of the filter via a pipe (14).

Abstract:
A seal (15) is brought into contact with a filter media (F1), a filter pump (P2) is operated to start filtration, and a signal from a pressure sensor (25) is received. When a predetermined value is exceeded by the signal from the pressure sensor (25) , the filter pump (P2) is stopped, the seal (15) is separated from the filter media (F1), and take-up of one section of the filter by a filter collection roll (11b) is started. In finishing filter supply from a filter supply roll (11a), drive of a motor (11a) is stopped, and an alarm signal is transmitted. If the supply is not to be finished, one section of the filter (F1) is taken up by the filter collection roll (11b), and the next stage of filtration is entered.
