Description

Shell lifting type centrifuge

Technical Field

The utility model relates to a centrifugal device field especially relates to a shell over-and-under type centrifuge.

Background

For dry-wet separation of the material, a centrifuge may be used. The materials are poured into a rotary drum of the centrifuge, the materials are driven to rotate through the high-speed rotation of the rotary drum, and liquid in the materials is thrown out, so that the dry-wet separation of the materials is realized.

After the centrifugal work is finished, the rotary drum and the shell need to be cleaned, the clearance between the outer wall of the rotary drum and the inner wall of the shell is small, the cleaning difficulty is increased, generally, only clean water can be poured into the rotary drum, the rotary drum can be rotated to clean, the cleaning is not thorough, and improvement is needed.

And an annular sealing gasket is arranged at the top of the annular liquid storage cover.

The top of the shell is provided with a cover plate in a turnover mode, and the cover plate is provided with a feeding pipe extending downwards into the rotary drum.

And a liquid discharge pipe joint communicated with the annular liquid storage cover is arranged at the bottom of the base.

The bottom of the rotary drum is provided with a rotary shaft extending downwards to the lower side of the base, and the bottom of the rotary shaft is provided with a first belt pulley.

The base is provided with a motor pointing to the lower side, the bottom of an output shaft of the motor is provided with a second belt pulley corresponding to the first belt pulley, and a belt is arranged between the first belt pulley and the second belt pulley for transmission.

Wherein, the lifting driving device adopts a hydraulic cylinder.

The utility model has the advantages that: the utility model provides a shell over-and-under type centrifuge, the lift drive that has designed especially, can drive the lift of mount and shell, and centrifugal work during, the shell descends and combines with annular stock solution cover, carries out the cage cover of rotary drum, avoids the problem that liquid splashes, and after centrifugal work accomplished, rises through the shell and separates with annular stock solution cover, exposes the rotary drum outer wall, conveniently carries out the cleanness of rotary drum outer wall and shell inner wall, and is easy and simple to handle.
