A lifting mechanism for a high-tightness self-cleaning centrifuge

Abstract

The invention discloses a lifting mechanism for a high-sealing self-cleaning centrifuge, which includes a main shaft, a lifting shaft, a pulley pressure sleeve, a guide sleeve and a lifting shaft flange, wherein: a central hole is arranged inside the main shaft; There is a keyway, one end of the lifting shaft passes through the center hole and extends to the other side of the main shaft; the inner ring surface of the pulley pressure sleeve is flat keyed; the pulley pressure sleeve is located at one end of the main shaft and is set on the lifting shaft, and the pulley pressure sleeve is fixed to the main shaft , the flat key on the pulley pressure sleeve is stuck in the keyway, and the radial fixed axial sliding fit between the flat key and the keyway; the first oil seal and the first retaining ring are arranged between the pulley pressure sleeve and the outer ring surface of the lifting shaft; The guide sleeve is located at the end of the main shaft away from the pressure sleeve of the pulley and is set on the lifting shaft, and the guide sleeve is fixed to the main shaft; there is a second oil seal and a second retaining ring between the guide sleeve and the lifting shaft; the flange of the lifting shaft is fixed and installed on the lifting shaft. the top of the shaft. The structure of the invention has the advantages of stable operation and low noise.

Description

technical field [0001] The invention relates to the technical field of centrifuges, in particular to a lifting mechanism for a high-sealing self-cleaning centrifuge. Background technique [0002] A centrifuge is a machine that uses centrifugal force to accelerate the separation of different materials that need to be separated. Centrifuges are widely used in chemical industry, petroleum, food, pharmaceutical, mineral processing, coal, water treatment and shipbuilding and other departments. Among them, the drum and the main shaft for driving the rotating drum are the necessary structures of the centrifuge. However, the existing main shaft for driving the rotating shaft cannot adapt to some special centrifuge structures. Therefore, its structure needs to be improved. Contents of the invention [0003] Based on the technical problems existing in the above-mentioned background technology, the present invention proposes a lifting mechanism for a self-cleaning centrifuge with hi...
