Abstract
Abstract A multicell cyclone with a plurality of cyclone cells and a method for the production thereof, in which the cyclone cells of the multicell cyclone are combined into groups from which deposited particles are cleaned out by vacuum suction through channel structures. This permits better control of the discharge of separated particles. Vacuum suction of the separated particles can be effected, for instance, via openings ( 19 ) which are jointly provided for the group ( 21 ) of cyclone cells. The group of cyclone cells can furthermore be produced as a module, which can, for instance, be assembled from two parts ( 12, 13 ) in which like structural elements of a group of cyclones are combined into one respective part. This makes it possible to optimize the separation result with little structural complexity and at low production cost.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
133 words
A multicell cyclone comprising a plurality of cyclone cells, an intake side for the fluid to be cleaned, a discharge side for the cleaned fluid, and a cyclone housing with a particle discharge for substances separated from the fluid, wherein the cyclone cells are arranged in the cyclone housing in groups such that individual groups of cyclone cells are combined into individual modules, each of the modules having an individual module housing that cooperates with the cyclone cells therein to form a collection chamber for the separated substances, wherein the collection chambers are connected to the cyclone housing's particle discharge by channel structures, and wherein the channel structures have an expanded cross section, relative to the spacing of the cyclone cells of a group from each other, for carrying away the separated substances.
Claim 2
Dependent Claim
133 words
A multicell cyclone comprising a plurality of cyclone cells, an intake side for the fluid to be cleaned, a discharge side for the cleaned fluid, and a cyclone housing with a particle discharge for substances separated from the fluid, wherein the cyclone cells are arranged in the cyclone housing in groups such that individual groups of cyclone cells are combined into individual modules, each of the modules having an individual module housing that cooperates with the cyclone cells therein to form a collection chamber for the separated substances, wherein the collection chambers are connected to the cyclone housing's particle discharge by channel structures, and wherein the channel structures have an expanded cross section, relative to the spacing of the cyclone cells of a group from each other, for carrying away the separated substances.
Claim 3
Dependent Claim
30 words
A multicell cyclone according to claim 1 , wherein the groups of cyclone cells are arranged such that respectively adjacent cyclone cells touch one another and form closed channel structures.
Claim 4
Dependent Claim
19 words
A multicell cyclone according to claim 1 , wherein the modules can be individually installed in the cyclone housing.
Claim 5
Dependent Claim
25 words
A multicell cyclone according to claim 1 , wherein the groups of cyclone cells are arranged symmetrically around a central axis relative to one another.
Claim 6
Dependent Claim
30 words
A multicell cyclone according to claim 1 , wherein the channel structures comprise an annular channel, which encircles all the groups of cyclone cells and communicates with the particle discharge.
Claim 7
Dependent Claim
47 words
A multicell cyclone according to claim 1 , wherein at least one cyclone cell of a group of cyclone cells is replaced by a dummy tube which creates a connection between the intake and the channel structures having a lower flaw resistance than the replaced cyclone cell.
