Definitions
- the present invention relates to a centrifuge with a centrifugal drum, a solids collection container arranged below the centrifugal drum and with a vibration measuring device for detecting vibrations of the
- the vibration measuring device can record and evaluate vibrations caused by the centrifugal drum, with the results obtained then alternatively causing a change in the operating parameters, possibly even switching off the centrifuge, in order to avoid damage.
- a warning signal can be activated by which the operating personnel is prompted to check a centrifuge which is obviously no longer running under optimal operating conditions.
- the present invention has for its object to design a centrifuge of the generic type so that the occurrence of vibrations with impermissible strength or height due to contact of the centrifugal drum with the contents in the solids collection container can be safely avoided.
- This object is achieved in that at least one sensor projecting beyond the lowest level of the centrifugal drum is attached to the centrifugal drum, which first contacts the medium in the solids collection container when the fill level in the solids collection container rises, so that before the centrifugal drum contacts the medium uncritical
- Vibrations are generated, which are detected and evaluated by the vibration measuring device.
- This comparatively simple construction which is inexpensive to manufacture, ensures that vibrations with absolutely uncritical strength are generated well before contact is made between the centrifugal drum and the medium collected in the solids collecting container, which vibrations can be detected and evaluated by the vibration measuring device, so that in any case larger ones Damage that can occur with vibrations of inadmissible strength or height can be avoided.
- the single figure shows a sectional view through a centrifuge according to the invention.
- the centrifuge shown in the drawing in section is with a
- Centrifugal drum 1 equipped, which at least partially protrudes into a solids collection container 2 arranged below the centrifugal drum 1.
- the centrifuge is in a known manner with any and therefore not shown vibration measuring device for detecting
- At least one sensor 3 protruding beyond the lowest level of the centrifugal drum 1 is attached to the centrifugal drum 1 and, when the fill level in the solids collection container 2 rises (as indicated by the dash-dotted line), first contacts the medium 4 located in the solids collection container. If this occurs, slight, uncritical vibrations arise which can be detected and evaluated by the vibration measuring device.
- a sensor 3 can be arranged in the axis of rotation 5 of the centrifugal drum 1. It also follows from the drawing that further sensors 3 can also be arranged outside the axis of rotation 5 of the centrifugal drum 1.
- the sensors 3 can have the shape of cylindrical pins, but the sensors 3 can also have other geometric cross-sectional shapes.
- the sensors 3 can be selected depending on the product, ie depending on the respective medium 4.
- Centrifugal drum 1 the possibility is realized to bring these sensors 3 in front of the centrifugal drum 1 into contact with the medium 4 rising in the solids collection container 2 and thereby to generate vibrations in the uncritical range, which can be detected by the vibration measuring device of the centrifuge and evaluated accordingly.
- vibration measuring device Any known and suitable vibration measuring device can be used as the vibration measuring device.
- vibrations used in the above description also means vibrations.
