Abstract
Abstract In a hydrocyclone arrangement at least two hydrocyclones are spaced laterally apart with a filling chamber, an overflow chamber and an underflow chamber arranged centrically of the hydrocyclones. The filling chamber is aligned above the overflow chamber and the underflow chamber is aligned below the overflow chamber. The hydrocyclones are disposed obliquely of the vertical so that the underflow from each is directed into the underflow chamber. The filling chamber has a spherical configuration and a separate connection extends radially outwardly from the filling chamber to each of the hydrocyclones. A supply connection extends vertically upwardly into the filling chamber passing vertically through the overflow chamber and then extending horizontally outwardly or continuing to proceed vertically through the underflow chamber. Replaceable wear protection parts are positioned in the filling chamber and the filling chamber is constructed so that it can be opened for access to the wear protection parts. Further, the wear protection parts can be arranged to form enclosed wear indication spaces within the filling chamber connected through a tubular member with the outside atmosphere. Each of the filling chamber, overflow chamber and underflow chamber can be divided in two by vertical partitions for forming independent functional groups of the separate chambers each associated with a different hydrocyclone.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
160 words
Hydrocyclone arrangement, including at least two laterally spaced hydrocyclones, a common filling chamber, a common overflow chamber and a common underflow chamber positioned centrally of said cyclones with said underflow chamber located below said filling chamber and said overflow chamber, each of said hydrocyclones disposed at an angle to the vertical with its underflow outlet directed toward said underflow chamber for flow thereto, wherein the improvement comprises that said filling chamber is located above said overflow chamber with said filling chamber, said overflow chamber and said underflow chamber in vertical alignment, a separate feed connection extending directly between said filling chamber and each of said hydrocyclones with each said feed connection extending outwardly in a straight line from said filling chamber to said hydrocyclone to which it is connected, a supply pipe connected to the lower end of said filling chamber and extending centrally downwardly therefrom through said overflow chamber and said overflow chamber positioned laterally inwardly from said hydrocyclones.
Claim 2
Dependent Claim
160 words
Hydrocyclone arrangement, including at least two laterally spaced hydrocyclones, a common filling chamber, a common overflow chamber and a common underflow chamber positioned centrally of said cyclones with said underflow chamber located below said filling chamber and said overflow chamber, each of said hydrocyclones disposed at an angle to the vertical with its underflow outlet directed toward said underflow chamber for flow thereto, wherein the improvement comprises that said filling chamber is located above said overflow chamber with said filling chamber, said overflow chamber and said underflow chamber in vertical alignment, a separate feed connection extending directly between said filling chamber and each of said hydrocyclones with each said feed connection extending outwardly in a straight line from said filling chamber to said hydrocyclone to which it is connected, a supply pipe connected to the lower end of said filling chamber and extending centrally downwardly therefrom through said overflow chamber and said overflow chamber positioned laterally inwardly from said hydrocyclones.
Claim 3
Dependent Claim
29 words
Hydrocyclone arrangement, as set forth in claim 1, wherein said filling chamber is spherically shaped and said feed connections extend radially outwardly from said filling chamber to said hydrocyclones.
Claim 4
Dependent Claim
33 words
Hydrocyclone arrangement, as set forth in claim 1, wherein said supply pipe extends centrally downwardly through said underflow chamber, and said underflow chamber has outlet connections disposed laterally outwardly from said supply pipe.
Claim 5
Dependent Claim
34 words
Hydrocyclone arrangement, as set forth in claim 1, wherein means are arranged for forming a collecting chamber in communication with the upper end of said filling chamber for affording degasification of said filling chamber.
Claim 6
Dependent Claim
36 words
Hydrocyclone arrangement, as set forth in claim 1, wherein replaceable wear protection means are located within said filling chamber and said filling chamber is formed of separable parts for affording access to said wear protection parts.
Claim 7
Dependent Claim
63 words
Hydrocyclone arrangement, as set forth in claim 5, wherein wall means are positioned within said filling chamber and arranged in combination with said wear protection means for forming a closed wear indication chamber within said filling chamber, a tubular member extending through said filling chamber and communicating between the interior of said wear indication chamber and the atmosphere exteriorly of said filling chamber.
Claim 8
Dependent Claim
30 words
Hydrocyclone arrangement, as set forth in claim 5, wherein said wear protection means includes a hemispherical shaped wear protection part spaced inwardly from the innver surface of said filling chamber.
Claim 9
Dependent Claim
27 words
Hydrocyclone arrangement, as set forth in claim 7, wherein said wear protection means includes a horizontally arranged circular disc disposed within said hemispherically shaped wear protection part.
Claim 10
Dependent Claim
69 words
Hydrocyclone arrangement, as set forth in claim 7, wherein an arcuately shaped wall is positioned between the upper part of said filling chamber and said hemispherically shaped wear protection part and is joined to said wear protection part for forming a closed chamber therebetween, and tubular connection means extending between said closed chamber and the outside Atmosphere so that it is in pressure free communication with the outside atmosphere.
Claim 11
Dependent Claim
157 words
Hydrocyclone arrangement, as set forth in claim 1, wherein a first vertical partition is positioned within said filling chamber and divides said filling chamber into two separate halves each associated with a different said hydrocyclone, a second vertical partition within said overflow chamber dividing it into two separate halves with each half associated with a different said hydrocyclone, and a third vertical partition positioned within said underflow chamber dividing it into two separate halves with each half associated with a different said hydrocyclone, a separate supply pipe connected to each of said halves of said filling chamber, a separate outlet from each of said halves of said underflow chamber, wear protection means located within each of said halves of said filling chamber, and said hydrocyclone arrangement providing two functional groups each including at least one different said hydrocyclone, one half of said filling chamber, one half of said overflow chamber and one half of said underflow chamber.
Claim 12
Dependent Claim
44 words
Hydrocyclone arrangement, as set forth in claim 1, wherein an arcuately bent overflow connection extends from the upper end of each said hydrocyclone to said overflow chamber with the upper limit of said overflow connections located below the upper limit of said filling chamber.
Claim 13
Dependent Claim
50 words
Hydrocyclone arrangement, as set forth in claim 1, wherein a portion of said supply pipe spaced below said overflow chamber extends horizontally outwardly from the portion which extends centrally downwardly through said overflow chamber and said horizontally arranged portion is located below said overflow chamber and above said underflow chamber.
