#CMT# #/CMT# The device has a suction head (13) that is height-adjusted by a controller and immersed into a bulk material (11). The bulk material is sucked by suction openings (18') that are arranged at lower end. Distance (h) between a sensor (20) e.g. ultrasonic sensor, at another suction head (10) and a level surface (11') of the bulk material is measured and forwarded to the controller. A housing (15) is provided at lower end of a suction muzzle (18) with suction openings. The sensor is provided with a cylindrical measuring housing (21). #CMT#USE : #/CMT# Device for emptying a bulk material e.g. free-flowing bulk material such as plastic resin and dyes, and non free-flowing bulk material such as granule, from a bag-like container. #CMT#ADVANTAGE : #/CMT# The distance between the sensor at the suction head and the level surface of the bulk material is measured and forwarded to the controller, thus achieving sucking of the bulk material in a safe and simple manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side view of a suction head of a device for emptying a bulk material from a bag-like container. h : Distance 10, 13 : Suction heads 11 : Bulk material 11' : Level surface 15 : Housing 18 : Suction muzzle 18' : Suction openings 20 : Sensor 21 : Cylindrical measuring housing. |
