Centrifugal machine with double-layer rotary drum structure

Abstract

The invention discloses a centrifugal machine with a double-layer rotary drum structure. The centrifugal machine comprises a main shaft and a rotary drum connected with the main shaft; the rotary drum is divided into an outer rotary drum body and an inner rotary drum body, the inner rotary drum body is located inside the outer rotary drum body, and a cavity is formed by the side portion of the inner rotary drum body and the outer rotary drum body; the main shaft penetrates the cavity to be connected with the inner rotary drum body, and therefore the outer rotary drum body and the inner rotary drum body rotate in the negative directions; slant sliding ways are arranged on the inner rotary drum body and the outer rotary drum body and are communicated with the cavity, and a suction tube is arranged in the cavity; and a filtering medium is installed on the inner layer of the inner rotary drum body, a feeding tube, a scraper and a discharging hopper are contained in internal space of the inner rotary drum body, and the scraper is located nearby the filtering medium. Though the double-layer structure of the inner rotary drum body and the outer rotary drum body, solid-liquid separation is efficiently achieved, and meanwhile vibration can be effectively avoided.

Description

Technical field [0001] The invention relates to the technical field of centrifuges, in particular to a centrifuge with a double-layer drum structure. Background technique [0002] With the continuous breakdown of the industrial division of labor, the requirements for product processing quality are getting higher and higher. In the process of solid-liquid separation in the prior art centrifuge, when a rotating drum is used for separation, after a period of use, often Vibration will occur, not only causing unstable feeding, but also affecting separation efficiency. Summary of the invention [0003] In order to solve the above technical problems, we proposed a centrifuge with a double-layer drum structure. By using the double-layer structure of the inner drum and the outer drum, the solid-liquid separation can be efficiently realized while effectively avoiding vibration. To achieve the above objective, the technical solution of the present invention is as follows: A centrifuge with ...

[0002] With the continuous specification of industrial division of labor, the requirements for product processing quality are getting higher and higher. In the process of solid-liquid separation, centrifuges in the prior art use drums for separation. After a period of use, they often There will be vibration, which will not only cause unstable feeding, but also affect the separation efficiency
