If the water level upstream of the screen rises above a set threshold, a level sensor can trigger the machine to restart even while in the Work Pause phase. The machine stops in pause mode only if the rake has reached a specific position above water level and after discharge has taken place. The machine is driven by a gearmotor that raises and lowers the rake. During the downward stroke, the cleaning rake stays open until it reaches the lowest position. When the cleaning rake reaches the bottom of the channel, the chain brings it close to the screen. During the upward stroke, the rake cleans the screen and retains the screened material inside it. Before the rake reaches the top position, a dedicated device cleans its inner part and discharges the screened material outside into a skip or onto a conveyor belt. At the top point, a limit switch controls the rake's movement.\r\n

OPERATING DESCRIPTION:<\/h6>\r\nThe machine is controlled by a pause-work timer. If the water level upstream of the screen rises above a set threshold, a level sensor can trigger the screen to restart even while in the Work Pause phase. The screen stops in pause mode only if the rake has reached a specific position above water level and after discharge has taken place. The machine is driven by 1 gearmotor for raising and lowering the rake, and by a hydraulic cylinder controlled by a power unit for engaging and disengaging the rake from the screen. During the downward stroke of the carriages, the cleaning rake stays open until it reaches the lowest position. When the cleaning rake reaches the bottom of the channel, a limit switch stops the descent. The hydraulic piston engages the rake with the screen and, via a signal, the gearmotor restarts, lifting the rake \u2014 now engaged with the screen \u2014 up to the discharge point. The piston is fitted with two internal proximity sensors that allow full opening or closing. During the upward stroke, the rake cleans the screen and retains the screened material inside it. Before it reaches the top position, a dedicated device cleans the inner part of the rake and discharges the screened material into a skip or onto a conveyor belt. At the top point, a limit switch stops the motor driving the screen's lift and reverses its motion, starting the downward stroke. Meanwhile, the hydraulic cylinder moves the cleaning rake away from the screen.\r\n

OPERATING DESCRIPTION:<\/h6>\r\nThe machine is controlled by a pause-work timer. If the water level upstream of the screen rises above a set threshold, a level sensor can trigger the screen to restart even while in the pause phase. The machine stops in pause mode only if the bucket has reached a specific position above water level and after discharge has taken place. The machine is driven by 2 gearmotors: one drives the lifting of the cleaning rake, and the other drives the unit that engages and disengages the rake from the screen. At the top of the control unit there are 3 drums: 2 side drums and 1 central drum. The drums are driven by a gearmotor and wind\/unwind the cables that raise and lower the cleaning rake. The second gearmotor drives a pulley that winds and unwinds the central cable, causing the bucket to move toward and away from the screen. During the downward stroke of the carriage, the bucket stays open until it reaches the lowest position. When the bucket rests on the bottom, the hoist cable slackens and a limit switch (connected to the cable tension) stops the gearmotor. The rotation direction of the 1st gearmotor is reversed, and the second gearmotor is activated, winding in the central cable so that the bucket engages with the screen. The upward stroke then takes place, during which the bucket cleans the screen and retains the screenings inside it. Before the bucket reaches the top position, a dedicated device cleans its inner part and discharges the material into a skip or onto a conveyor belt. At the top point, a limit switch stops the motor driving the screen's lift and reverses its motion, starting the downward stroke. Meanwhile, the 2nd gearmotor drives the central drum, moving the cleaning rake away from the screen. The downward stroke takes place with the bucket kept clear of the screen.\r\n

OPERATING DESCRIPTION<\/h6>\r\nThe machine is controlled by a pause-work timer. If the water level in the feed tank rises above a set threshold, a level sensor can trigger the machine to restart even while in the Work Pause phase. The water to be treated enters the feed compartment and is distributed over the entire surface of the drum. Filtration occurs from the outside toward the inside of the drum. The water that has entered the drum flows out from the inside toward the outside of the drum. In this way, the screening drum is kept continuously self-cleaning. The solids screened on the outer surface of the drum are removed by a scraper blade and, optionally, with the help of a motorized brush. Feed can be by gravity or by pump\r\n

OPERATING DESCRIPTION<\/h6>\r\nThe machine is controlled by a pause-work timer. Depending on the application, the machine can be started by a water level sensor in the feed tank, or by a flow sensor in the feed or drain pipe. The water to be treated enters the feed compartment and is distributed over the entire surface of the belt. Filtration takes place by gravity; the solids are retained by the belt and are then removed by a system of motorized rotating brushes. After discharge, the belt is continuously washed by a high-pressure water washing system. In this way the belt is kept continuously self-cleaning. Feed can be by gravity or by pump\r\n

CALCULATION OF THE HEAD LOSS<\/h6>\r\nAmong the phenomena of backed up outflow, we have also the passage through bar screens (the bars length is placed in the stream flowing direction). The bars may have different sections and angles of inclination (\u03b1) on the horizontal line (Picture FG1). The head loss through a bar screen is determined by means of the KIRSHMER\u2019s formula:\r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n\"\"\r\n\r\nwhere: - v : water velocity without the bar screen; - \u03b1: angle of inclination of the bar screen on the horizontal line; - d : bars thickness; - a: spacing between the bars; - \u03b2: coefficient of shape, function of the bar section, as shown in the picture.\r\n\r\nBasically, the value:\r\n\r\n\"\"\r\n\r\nrepresents a head loss which causes a \u201cbackup\u201d of water upstream or downstream the bar screen, according to whether the stream speed is slow or fast.\r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n \r\n\r\n
