Discharge device adjustable centrifugal machine

Abstract

The invention provides a discharge device adjustable centrifugal machine which comprises a chassis, a rotating drum, an inner discharge device and an outer discharge device, wherein the rotating drum is rotationally mounted in the chassis and is driven to rotate by a first driving device; the inner discharge device comprises a second driving device, a driving rod, a connecting assembly and a cutter assembly; the driving rod stretches into the rotating drum from the upside; the second driving device drives the driving rod to move up and down; the outer discharge device comprises a vent pipe stretching into a part between the chassis and the rotating drum; a plurality of nozzles are formed on the vent pipe; the vent pipe is communicated with a blower; the nozzles face towards the rotating drum; the cutter assembly comprises a cutter rest, a cutter and a hair brush; and the cutter and the hair brush are respectively arranged on the two sides of the cutter rest. The discharge device adjustable centrifugal machine discharges more easily and cleanly, and the service life is increased.

Description

technical field [0001] The invention relates to the technical field of centrifuges, in particular to a centrifuge with an adjustable discharge device. Background technique [0002] Existing vertical centrifuges mostly use a scraper to unload the filter cake. If a wide scraper is used to unload the filter cake, it will be carried out along the entire height of the drum, and the unloading is rapid. However, the wide scraper has a large chip resistance, so it is mostly suitable for For loose filter cakes and low drum heights, use a narrow scraper to unload chips with little resistance, and can be used for unloading filter cakes with different hardness or a little viscosity. When unloading with a narrow scraper, the solid phase at the edge cannot be pulled smoothly. In the process of centrifugal dehydration of the material, the solid phase forms a gradually thicker filter cake from top to bottom along the drum under the action of gravity and centrifugal force. Since the angle of...

[0002] Existing vertical centrifuges mostly use a scraper to unload the filter cake. If a wide scraper is used to unload the filter cake, it will be carried out along the entire height of the drum, and the unloading is rapid. However, the wide scraper has a large chip resistance, so it is mostly suitable for For loose filter cakes and low drum heights, use a narrow scraper to unload chips with little resistance, and can be used for unloading filter cakes with different hardness or a little viscosity. When unloading with a narrow scraper, the solid phase at the edge cannot be pulled smoothly. In the process of centrifugal dehydration of the material, the solid phase forms a gradually thicker filter cake from top to bottom along the drum under the action of gravity and centrifugal force. Since the angle of the cutter is not adjustable, the scraping During the filter cake process, the force on the bottom of the cutter is relatively large, the force on the cutter is uneven, and the cutter is easy to be damaged
