A concentrated filter centrifuge and its transmission device

Abstract

The invention discloses a concentrated filter centrifuge in which the inner and outer shafts only transmit power and does not need to support the conveying screw and the drum, and the transmission device therein. The transmission device includes: a machine base, a differential, a hollow outer shaft and a movable The inner shaft pierced in the outer shaft, and the differential is movably set on the machine base through the support cylinder, and the hollow shaft seat reinforcement shaft is arranged on the said machine base, and the outer shaft is movably arranged in the shaft seat reinforcement shaft, and the drum The connecting cylinder is movably arranged on the shaft seat reinforcement shaft; the other side of the connecting cylinder is connected with the corresponding end of the outer shaft through the outer shaft transmission part, and the other end of the outer shaft is connected with the outer drive shaft of the differential, and the conveying screw It is movably supported on the connecting cylinder, the corresponding end of the inner shaft passes through the outer shaft, and is connected with the middle part of the conveying screw through the inner shaft transmission part, and the other end of the inner shaft is connected with the inner drive shaft of the differential. The concentrating filter centrifuge equipped with the transmission device has a wide range of uses, and is especially suitable for the fields of pharmacy, chemical industry, environmental protection and the like.

Description

technical field [0001] The invention relates to a centrifuge, in particular to a concentrating filter centrifuge and a transmission device therein. Background technique [0002] At present, the traditional concentrated filter centrifuge adopts the structure of one-side support and side-opening door, which greatly facilitates the replacement of the filter screen, and is favored by the majority of users. However, due to the short settling section of this traditional concentration filter centrifuge, the concentration effect is not very satisfactory (the solid phase content is higher in the supernatant liquid). For this reason, many manufacturers just solve the problem by simply lengthening the settlement section without any adjustment or improvement in the transmission device, so that the corresponding end of the inner shaft must support the conveying screw at a single point and the corresponding end of the outer shaft. It is necessary to support the drum at a single point, re...

Problems solved by technology

However, due to the short settling section of this traditional concentrating filter centrifuge, the concentrating effect is not very ideal (the solid phase content is higher in the supernatant liquid)

For this reason, many manufacturers just solve the problem by simply lengthening the settlement section without any adjustment or improvement in the transmission device, so that the corresponding end of the inner shaft must support the conveying screw at a single point and the corresponding end of the outer shaft. It is necessary to support the drum at a single point, resulting in relatively large shaking when the inner and outer shafts rotate, which greatly shortens the service life of the inner and outer shafts and other related parts; in addition, in order to ensure the filtering effect, the distance between the conveying screw and the drum should not be too large In this case, due to the large sway of the inner and outer shafts, during the working process, the conveying screw is very easy to touch the filter screen on the drum, causing damage to the filter screen and affecting the normal operation of the thickening filter centrifuge
