Bag turning centrifugal machine, and dehydration and filter cloth regeneration method thereof

Abstract

The invention belongs to the technical field of centrifugal filtration type solid-liquid separation and particularly relates to a bag turning centrifugal machine, and a dehydration and filter cloth regeneration method thereof. The bag turning centrifugal machine comprises a rotating drum rotatably arranged in a case and fixedly connected with a hollow spindle, and the open end of the rotating drumis provided with a front push disc. The rotating drum is further internally provided with a rear push disc fixedly connected with the front push disc, and the hollow spindle is internally provided with a moving shaft capable of axially moving relative to the hollow spindle. The moving shaft is fixedly connected with the rear push disc, and the bag turning centrifugal machine further comprises a locking device which is fixedly arranged on the side, away from the rotating drum, of the moving shaft. Through the elasticity effect, the locking device enables the front end face of the rotating drumand the front push disc to be in a sealed state when the front end face of the rotating drum and the front push disc are attached. The locking device, used for locking and sealing the front end faceof the rotating drum and the front push disc, in the bag turning centrifugal machine is simple and compact in structure, convenient to operate and maintain and capable of effectively reducing and eveneradicating the phenomena of leakage and venting.

Description

technical field [0001] The invention belongs to the technical field of centrifugal filter type solid-liquid separation, in particular to a bag-turning centrifuge and its dehydration and filter cloth regeneration method. Background technique [0002] As a kind of centrifugal filter solid-liquid separation equipment, bag turning centrifuge is widely used in pharmaceutical, chemical, food and other industries. The working process of bag turning centrifuge mainly includes feeding, filtering, washing, dehydration, discharging, filter cloth regeneration stage. The drum cavity is the intersection point of the inner shaft system (front push plate, rear push plate, feed pipe, etc.) The core component in the centrifuge. The tightness of the drum cavity is related to whether the centrifuge can work normally and whether the materials can be processed normally, which is a key issue in the core components. Because the front push plate and the front end of the drum are in different bond...

AI Technical Summary

Problems solved by technology

[0003] At present, a hydraulic device is used to generate hydraulic pressure between the front end of the drum and the front push plate in the bag-turning centrifuge for locking and sealing. Drip and other problems, and then cause pollution. In the occasions with high hygienic requirements such as pharmaceuticals, biology, and food, these problems are not allowed
