Waste centrifugal extractor

Abstract

The invention relates to the technical field of garbage treatment equipment, and particularly relates to a waste centrifugal extractor. The waste centrifugal extractor comprises a shell; bases are arranged under the bottom surface of the shell; a damping device is arranged in each base; a mixing groove is formed in the shell among the bases; a rotary drum is arranged in the shell; a stabilizing device is arranged between the rotary drum and the shell; a first transmission shaft, a second transmission shaft and a third transmission shaft are arranged in the rotary drum and the shell; the otherend of the first transmission shaft penetrates through the top surface of the shell and is connected with a centrifugal motor; the other end of the third transmission shaft is rotationally connected with the bottom surface of the mixing groove; a hub is arranged at the middle of the second transmission shaft; a flow baffle plate is arranged at the joint of the second transmission shaft and the third transmission shaft; and an impeller and a vortex guide vane are sequentially arranged at the tail end of the third transmission shaft. Due to the damping device and the hub, vibration of the rotarydrum is reduced, so that the rotating speed of the rotary drum can be higher; the mixing groove, and the impeller and the vortex guide vane on the third transmission shaft are arranged on the bottomsurface of the shell, so that two-phase materials can be well mixed; and the flow baffle plate can reduce the liquid outlet speed of light phase liquid and heavy phase liquid.

Description

technical field [0001] The invention relates to the technical field of waste treatment equipment, in particular to a waste centrifugal extractor. Background technique [0002] The working process of the centrifugal extractor is mainly divided into two parts: the mixing mass transfer process and the centrifugal separation process. The two liquids to be mixed are mixed under the rotation of the drum or paddle of the centrifugal extractor. The liquid enters the drum and rotates at a high speed driven by the drum to generate centrifugal force. Under the action of centrifugal force, the liquid with high density gathers outward, and the liquid with low density gathers inward. The two liquids will gradually stratify to form an interface. The denser liquid on the outside exits the extractor through the heavy phase outlet, and the less dense liquid on the inside exits the extractor through the light phase outlet, thus completing the separation process. Moreover, when the main shaft ...

Problems solved by technology

Moreover, when the main shaft drives the drum at the end to rotate at high speed, it will cause the centrifugal extractor to vibrate. The higher the speed, the more serious the vibration, which limits the speed of the drum and makes the mixing and separation of light and heavy phases not good enough.
