Description

H. NAESS APPARATUS FOR CLEANING CENTRIFUGAL SEPARATORS April 2, 1929.
Filed July 14. 1926 Patented Apr. 2, 1929.
UNITED STATES HALLVARD nnss, on Moss, NORWAY.
APPARATUS EUR CLEANING CENTRIFUGAL SEPARATORS.
Application filed July 14, 1926, Serial No. 122,470, and in Norway June 18, 1925.
In allcentriiugal separators hitherto used, wherein sets Vot plates are used, the set ot plates must, after the separating operation, be cleaned and dried carefully in order to remove deposited impurities and to prevent the rusting` of the plates. Thisis eilected either by separating the plates trom one another.' and cleaning the .several plates and the distril'niting` cross separately, or the cross is placed in the bowl body oit the separator', after having cleaned the saine -from dirt, and the impurities oi' the plates are flung out into the bowl body, whereupon the separator must' again be .stopped and' the bowl body be cleaned anew. This cleansing has also been eliected by simply imnn-n'singl the plate set et the centrifugal separators in a cleansing fluid and rotating said plate set in the liquid. rlhese operatioiis are Very time-wasting, and in case ot a continuous separation the work rendered by the separator considerably reduced on account ot this slow cleaning process. Thereby the practical. use o't the centriiugal separators rather limited.
The present invention has tor its object the provision ot an apparatus for centri'liiii- `rally cleaning the plate set and the distributingcross tending` to shorten the cleaning1 period and obtain simultaneously a con'iplete cleaning` ot plate set and distributing cross. In the liollowinn the invention wiilbe described with relerence to the annexed drawinpr showing a sectional view oi an apparatus in accordance with my invention.
.in order to clean the plate set 2 the saine together with the distributiniv cross 3 are taken out lirointhe bowl body and a re placed within a special cleaning' bowl body Ll; which may be set. in rotation by means of a spindle l. flhe eyliniflric part (wall) oli this bowl body is, contrary to the solid walls ci the ordinary bowl bodies, perforated by slotsi), holes or the like. l
For the complete cleaningl ot plates and cross a cleaning medium nnist be si'ipplied, which is supplied to the plateset by the san'ie path as that by which the lightest liquid leaves Vthe plate set during the separating operation (at the innrr edges ol' the plates). The cleaning medium is supplied either by means ot a special top piece 5 placed on the top of the plate set and so constructed that the cleaning medium through the channels of the distributing cross and through the in ner holes olI the plates tlows in between the plates, or the ordinary top piece (upper plate with neck) is retained. ln such case the said piece must be ot such a construction that the outlet apertures in the` neck may also serve as a receiver tor the cleaningn medium. Either top piece keeps the hole cleaning device together by beingl screwed fast to the cleaning bowl body by means oi' a nut 6. The cleaning` medium is introduced into the neck of the top piece by means of a hopper 7, pipe or the like. This supply :is so arranged that alternately or simultaneously the cleaningn medium may be supplied to the interior oli/ and exterior of theclistiibutii'ig cross.
,During the rotation the cleaning medium thing out against the bowl body between the plates and cleans the same from within out wart ly. On account ol the bowl body being perforated the cleaning medium and all impurities aretlung out through the aperture o't the cleaning bowl body but are prevented by a shield 8 from beingl flung out into the space. i
With this cleaning apparatus the whole plate set can be cleaned and dried completely in a minimum ot time.
` The cleaning medium may be in a liquid or a gaseous state, and it desired a special dryingl medium may be used after accomplished cleaning.
Claim:
.elipparatus for eentilfngal cleaning oit' the plate set and the distributing` cross ot centrifuga-l separators, comprisinr a bowl body tor receiving the set ot' separator plates and distributijnp` cross to be cleansed, means 'for rotatfinpr said bowl said distributing4 cross and the plate set carried thereby, a top piece 'lor suprnying the cleaning medium to the inner edgesoit said separator plates, and means :for allowing said cleaning medium together with the impurities removed thereby to escape :troni lsaid bowl.
ln t imony whereof I have signed my naine te this specification.
