Description
Technical Field
The invention relates to a sedimentation filter centrifuge, in particular to a mounting structure of a sedimentation and filtration mechanism in the sedimentation filter centrifuge.
Background
Currently, there are two general arrangements of settling devices and filtering devices in a conventional settling filter centrifuge, one arrangement is shown in fig. 6, in which the settling devices and the filtering devices are serially arranged along one direction, the settling devices and the filtering devices share a settling filter screw mounting shaft 16, the settling screw 18 and the filtering screw 19 are serially mounted on the settling filter screw mounting shaft 16 (in which the filtering screw 19 is indirectly mounted on the settling filter screw mounting shaft 16 through a filtering screw mounting cylinder 190), and the settling drum 15 is serially connected with the filtering drum 17, thus making the whole body excessively long. It is known that the sedimentation and filtration effects of the centrifuge can be ensured only when the centrifuge reaches a certain rotation speed, and then, as the machine body is too long and the rotation speed of the centrifuge is too high, the sedimentation and filtration spiral installation shaft 16, the sedimentation rotary drum 15 and the filtration rotary drum 17 are supported to vibrate more and more, so that the sedimentation and filtration effects of the sedimentation and filtration centrifuge are seriously affected because the sedimentation and filtration centrifuge with the structure cannot work in a high-speed mode; if the device is forced to work in a high-speed mode, bearings for supporting the sedimentation filter screw installation shaft 16 and the sedimentation drum 15 and the filter drum 17 are damaged, so that serious safety accidents are caused, and personal safety of surrounding personnel is affected. Another arrangement is shown in fig. 7, in which the filter spiral 19 of the filter device is mounted directly on the sedimentation drum 15, which on the one hand increases the manufacturing difficulty considerably; on the other hand, since the right end of the settling drum 15 needs to be supported on the settling screw mounting shaft 161 through the settling drum bearing 150, the settling screw mounting shaft 161 is connected to the filter drum 17, which corresponds to the settling drum 15 being connected to the filter drum 17 through the settling drum bearing 150, namely: the sedimentation drum 15 and the filter drum 17 cannot be rigidly connected, so that the left main bearing 11 supporting the sedimentation drum 15 and the right main bearing 12 supporting the filter drum 17 cannot work in a high-speed mode, and the sedimentation and filtering effects of the sedimentation and filtering centrifuge are seriously affected; if the left and right main bearings 11 and 12 are forcibly operated in the high speed mode, they are damaged due to excessive vibration, causing serious safety accidents, and affecting personal safety of surrounding persons.
