Patent number: 11904435Abstract: A water-abrasive suspension cutting facility includes a high-pressure source (3) for providing (301) water at a high pressure, a high-pressure conduit (5) which is connected to the high-pressure source (3), a pressure tank for providing (303) a water-abrasive agent suspension (13) which is at a high pressure, a lock chamber (21) which is designed to temporarily be at a high pressure and temporarily at a low pressure, and a filling valve (23) for filling (311) the lock chamber when this is at a low pressure. A pump (31) at the suction side is fluid-connected to the lock chamber in a manner capable of being shut off, in a manner such that given high pressure in the lock chamber (21) the pump is shut off from this and given low pressure in the lock chamber (21) the pump is in the position of sucking an abrasive agent suspension through the filling valve (23) into the lock chamber (21).Type: GrantFiled: March 31, 2017Date of Patent: February 20, 2024Assignee: ANT Applied New Technologies AGInventor: Marco Linde

Patent number: 11511392Abstract: A water-abrasive suspension cutting facility (1) includes a high-pressure source (3) for providing (301) water at a high pressure, a high-pressure conduit (5) which is connected to the high-pressure source (3) and a pressure tank (11) for providing (303) an abrasive agent suspension (13) which is at a high pressure. The pressure tank (11) is fluid-connected to the high-pressure conduit (5) via a regulatable throttle (17). The throttle (17) is arranged at the entry side of the pressure tank (11) and is configured to regulate the feed flow into the pressure tank (11) from the high-pressure conduit (5) in dependence on at least one control variable.Type: GrantFiled: March 31, 2017Date of Patent: November 29, 2022Assignee: ANT APPLIED NEW TECHNOLOGIES AGInventor: Marco Linde

Patent number: 11305401Abstract: A water-abrasive suspension cutting facility includes a pressure tank (11) for providing a water-abrasive agent suspension (13) which is under pressure, a lock chamber (21), and a refilling valve for refilling abrasive agent into the pressure tank via the lock chamber (21). The refilling valve (21) includes a valve entry (49), a valve exit (51), a valve space (71) which is arranged between the valve entry (49) and the valve exit (51), and a valve body (67) which is located in the valve space (71). The valve entry (49) is connected to the lock chamber (21) and the valve exit (51) to the pressure tank (11). The refilling valve (19) can assume a first closure position, a first open position and a second open position. In the first closure position the lock chamber (21) is fluid-separated from the pressure tank.Type: GrantFiled: March 31, 2017Date of Patent: April 19, 2022Assignee: ANT APPLIED NEW TECHNOLOGIES AGInventor: Marco Linde

Patent number: 10525569Abstract: A water-abrasive cutting system includes a cutting head (2) which includes a fixing device (16, 18, 20) for fixing the cutting head (2) on the wall to be cut as well as a nozzle head (10) disposed on the cutting head (2). At least one cutting nozzle (12), for an application of a cutting jet (14), is disposed in the cutting head (2). A cutting monitoring device (26) includes at least one hydrophone (30) and at least one further sensor. The cutting monitoring device (26) is configured to detect a complete penetration and/or cutting-through of the wall on the basis of the sensor signals of the hydrophone (30) and the at least one further sensor.Type: GrantFiled: February 18, 2015Date of Patent: January 7, 2020Assignee: ANT Applied New Technologies AGInventor: Marco Linde

Patent number: 10189144Abstract: A water-abrasive suspension cutting facility with at least one high-pressure source (2) which provides a carrier fluid at a high pressure, with at least one exit nozzle (6), with a high-pressure conduit (4) connecting the high-pressure source (2) to the exit nozzle (6), as well as with an abrasive agent feed lock (16). The abrasive agent feed lock (16) is connected to the high-pressure conduit (4) and includes an entry side shut-off element (26) and an exit-side shut-off element (24). A lock chamber (18) is arranged between the entry side shut-off element (26) and an exit-side shut-off element (24). A suction device (30) is configured for producing a reduced pressure in the lock chamber (18) and is connected to the lock chamber (18).Type: GrantFiled: April 4, 2014Date of Patent: January 29, 2019Assignee: ANT APPLIED NEW TECHNOLOGIES AGInventor: Marco Linde
