Description
Technical field
The utility model belongs to feed separation technical field, and in particular to a kind of disk centrifuge from buffering.
Background technique
Disk centrifuge is vertical centrifugal machine, and rotary drum is mounted in vertical shaft upper end, by transmission device by motor drive height
Speed rotation.There is one group of dish-shaped part -- disk being nested together mutually in rotary drum.There are between very little between disk and disk
Gap.Rotary drum is added by the feed pipe for being located at rotary drum center in suspension (or emulsion).When suspension (or emulsion) flows through disk
Between gap when, solid particle (or drop) is deposited on disk formation sediment (or liquid layer) under centrifuge effect.Sediment
Disk is detached from along disc surface sliding and accumulates in the maximum position of rotary drum interior diameter, and the liquid after separation is discharged from liquid outlet
Rotary drum.The effect of disk is the settling height for shortening solid particle (or drop), the settling area for expanding rotary drum, in rotary drum due to
It is mounted with disk and substantially increases the production capacity of seperator.It accumulates in the solid in rotary drum and is dismantled after seperator shutdown and turned
Drum is discharged from rotary drum in non-stop-machine situation by manually removing, or by slagging mechanism.
The deslagging mode of disc separator is divided into: artificial, automatic, three kinds of structures of nozzle, wherein automatic discharge is using the most
Extensively, working piston deslagging is one kind of automatic discharge, its principle is exactly to make working piston or more by special structure
Mobile, working piston moves up when work, forms a closed cavity, material is inside separated, when slag is run up to centainly
Degree, when need to be discharged, working piston is moved down outside slag and partially liq discharge rotary drum, to realize automatic discharge.
Since working piston and rotary drum body are metal parts, during working piston lifting, unavoidably
Rigid collision occurs between rotary drum body, can not only generate biggish work noise, but also will cause component wear.Except this
Except, in tapping process, since powerful centrifugal force acts on, the sealing surface and inclined-plane of working piston can be washed destruction, especially
It is that have the higher particle of hardness in liquid to be separated.After sealing surface destroys, it will cause leakage or even lose separation function.?
Under normal circumstances, replacement working piston is normal maintenance means, but it is costly to replace working piston, and need to return to production
Producer carries out dynamic balance check.Influence production.
