Die Erfindung betrifft eine Reinigungsvorrichtung (100), welche dreidimensionale Objekte (7, 14), die durch schichtweises Aufbringen und selektives Verfestigen eines pulverförmigen Aufbaumaterials hergestellt worden sind, von die Objekte (7, 14) umgebendem und/oder in Öffnungen oder Kanälen der Objekte (7, 14) verbliebenem, nicht verfestigtem pulverförmigem Aufbaumaterial reinigt, umfassend eine Reinigungskammer (5), in welcher die Reinigung eines Objekts (7, 14) stattfindet und welche wenigstens eine Auslassöffnung (18) zum Auslass des von dem Objekt (7, 14) abgereinigten Pulvers aus der Reinigungskammer (5) aufweist, wobei das abgereinigte Pulver die Auslassöffnung (18) passiert, eine Schwenkeinrichtung (16), an welcher das Objekt (7, 14) spannbar und durch welche das Objekt (7, 14) in Bezug auf wenigstens eine Schwenkachse (11, 12) in verschiedene Schwenkstellungen schwenkbar ist, eine elektronische Steuereinrichtung (22), welche die Schwenkvorrichtung steuert oder regelt, um die Schwenkstellungen des Objekts (7, 14) zu steuern oder zu regeln. Die Erfindung sieht vor, dass sie weiterhin eine Sensoreinrichtung (19) umfasst, welche eine Reinigungsgröße erfasst, die eine Menge, eine Masse, einen Massenstrom, ein Volumen und/oder einen Volumenstrom des die wenigstens eine Auslassöffnung passierenden, vom oder aus dem Objekt (7, 14) abgereinigten pulverförmigen Aufbaumaterials repräsentiert, wobei die elektronische Steuereinrichtung (22) die Schwenkeinrichtung (16) derart steuert oder regelt, dass die Schwenkstellungen des Objekts (7, 14) abhängig von der Reinigungsgröße gesteuert oder geregelt werden.
摘要:
The invention relates to an impact device for cleaning of surfaces, particularly heat delivery surfaces, such as boiler faces, the impact device comprising an anvil (1); a body (2); a hammer unit comprising a hammer (5) arranged to be displaceable in the body (2); and a spring (6) arranged to receive impact energy from the hammer (5) and to transfer impact energy to the anvil (1). To be able to effi- cienty damp undesired impact force from the anvil (1) to the body (2) such that the maintenance interval and service life of the impact device will be long, and to improve the efficiency and reliability of the impact device and to facilitate its maintenance, the body (2) is fastened to the anvil (1) by means of an elongated suspension element (7); the impact device comprises a spring unit (9) connecting the suspension element (7) to the body (2) flexibly, which allows the body (2) to be displaced in the longitudinal direction of the suspension element (7); the hammer device comprises an end facing the anvil (1), and the device comprises means for keeping an entity comprising the hammer unit end facing the anvil (1), the spring (6) and the anvil (1) under compression in a clearance-free manner.

The invention relates to a method and a cleaning device (1, 101) for removing deposits from interiors (54) of containers and systems (51) by means of explosive technology. The cleaning device (1, 101) contains a cleaning appliance (2, 102) having a receiving space (11, 111) and at least one pressure container (21, 21'; 121, 121') connected to the cleaning appliance (2, 102) via at least one metering fitting (18, 18'; 118, 118'). The introduction of the at least one gaseous component into the cleaning appliance (2, 102) is controlled in accordance with the principle of the pressure difference between a maximum pressure at the start of the introduction and a desired residual pressure following completion of the introduction. To this end, the desired residual pressure in the pressure container (21, 21'; 121, 121') is defined on the basis of the quantity of gaseous component to be introduced, starting from the maximum pressure, and the introduction of the at least one gaseous component is stopped when the desired residual pressure is achieved. The desired residual pressure is in this case in the positive pressure range.
摘要:
In order to perform work on an underwater pipe, an apparatus comprising an ultrasound emitting system and at least one ultrasound receiving transducer (20) is lowered into the marine environment. During an inspection phase, an ultrasound inspection source (14, 14a) of the ultrasound emitting system and the receiving transducer are disposed on each side of the pipe, the inspection source is activated, and an ultrasound signal captured by the receiving transducer is recorded. The inspection step further comprises detecting a condition for locating an obstruction at the location where the inspection source and the receiving transducer are disposed, in response to the observation of an anomaly in the ultrasound signal captured by the receiving transducer at said location. In a destruction phase, a power source (14, 14b) of the ultrasound emitting system is then coupled to the pipe at the aforementioned location, and the power source is activated in order to destroy the obstruction.
摘要:
The invention relates to an apparatus (1) for removing deposits in containers by blasting technology, said apparatus comprising at least one cleaning lance (2) having a handle-side and a cleaning-side end section (3a, 3b). A flexible thin-walled container (5) is mounted at the cleaning-side end section (3b) on a container connection (9a, 9b) and forms a receiving chamber (6) for an explosive gas mixture. The apparatus (1) further comprises a feed line (7) for feeding a flowable, explosive mixture or the starting components thereof to the receiving chamber (6) of the thin-walled container (5), and ignition means for triggering the explosion in the thin-walled container (5) and a control device for controlling ignition. The apparatus (1) is characterized by a plurality of container connections (9a, 9b) for connection to one thin-walled container (5) each, the control device being designed to be common such that explosion in the thin-walled containers (5) can be triggered by the common control device either simultaneously or delayed in time.
