Method of weighing out powdered substances using the loss-in-weight method and device for weighing powdered substances using the loss-in-weight method

摘要

The purpose of the notification is the method of weighing the pollutants with the lost weight method and the device (1) for weighing the pollutants with the lost weight method. The notification applies when weighing microportions precisely weighed for industrial applications in the pharmaceutical, chemical, food, etc. industry. The device (1) for weighing powdered flakes by the lost weight method contains the control system (2) and the dispenser (3) with the flue gas (4) of the flake substance,which is suspended on a tensiometric device (5) and together with it is a gravimetric device (6) which determines the instantaneous mass flow of the bulky substance before the portion of the substance is received. The dispenser (3) on the outside of its dispenser (4) has a vibrator mounted (7) producing dispenser vibration (3). The control system (2) and the adapter (8) controlling the vibrator (7) determine the release of the flux substance;Whereas a tensiometric device (5) is a pressure measurement device which determines the instantaneous load of the described coating of the components of the dosing device (3) together with the material transferred; whereas a dosing device (3) is preferably placed under the receptacle (9) receptacle. The connector (8) is the current generator connected by a piezoelectric element (10) with a vibrator (7) constituting a straight rod (7') which is a connector located longitudinally and closely behind the piezoelectric element (10) up to the throttle (4),with which the rod (7') is permanently and positively disconnected for the extension of the main axis X of the flue-out. The pass (4) is completed by a pearl (11) with eyes having a transverse range from 10 m to 1000 m, and a current generator (8') connected by a piezoelectric element (10) with a rod (7'),is an intermediate high-frequency rod vibration generator (7'),and through the rod (7') also a dosing device (3) of gravity, where the frequency of their vibrations increases from 15 kHz to 45 kHz.
