A pressure slag discharge type double-cone cylinder centrifuge

Abstract

The invention discloses a pressure deslagging type two-cone barrel centrifugal machine. The pressure deslagging type two-cone barrel centrifugal machine comprises long-cone barrels and short cone barrels; a varied-diameter screw pusher is arranged in the long-cone barrels and the short cone barrels, the varied-diameter screw pusher is provided with a screw centre shaft, and a plurality of screw blades are arranged on the outer lateral wall of the screw centre shaft; the varied-diameter screw pusher is provided with a first centripetal pump draining chamber, a buffer baffle is arranged at the back end of the varied-diameter screw pusher, and varied-diameter screw blades are arranged on the buffer baffle; the varied-diameter screw pusher is connected with a centripetal pump draining device, the centripetal pump draining device is provided with a clear liquid draining channel, and a second centripetal pump draining chamber is arranged at the front end of the clear liquid draining channel; a pipe seat is arranged at the back end of the clear liquid draining channel and is provided with a centripetal pump adjusting valve; and a feeding pipe is connected to the clear liquid draining channel in an inserted manner, and a pressure control mechanism is arranged at the back end of the feeding pipe. According to the pressure deslagging type two-cone barrel centrifugal machine, under the effect that the long-cone barrels and the short cone barrels are combined into a two-cone barrel assembly, the standing time of materials in the machine is prolonged, and the centrifugal force field at the position of the first centripetal pump draining chamber is maximum in the overall machine, and therefore a separating medium is clearer.

Description

technical field [0001] The invention relates to a double-cone cylinder centrifuge, in particular to a pressure slag discharge type double-cone cylinder centrifuge. Background technique [0002] Ordinary horizontal screw discharge centrifuges have been applied to the separation of various materials. Once the solids in these materials are settled and compressed, they have a certain volume and hardness and are easily transported by the machine. However, some materials "such as yeast , protein, fermentation broth, ultrafiltration residue, etc., very small particles, unable to be compressed, after settling, they have more liquid characteristics than solid characteristics, so it is difficult to transport solids to the centrifuge cone slag outlet, then There is a phenomenon of solid reflux, resulting in material blockage and inability to separate. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, so as to pro...
