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

1. 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 connected to the 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.

2. 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.

3. A multicell cyclone according to claim 1, wherein the groups of cyclone cells are combined into individual modules;

wherein the modules are each provided with a module housing that forms collection chambers for the separated substances, and wherein the collection chambers each have at least one opening to the channel structures of the cyclone housing.

4. A multicell cyclone according to claim 3, wherein the modules can be individually installed in the cyclone housing.

5. A multicell cyclone according to claim 1, wherein the groups of cyclone cells are arranged symmetrically around a central axis relative to one another.

6. 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.

7. 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 flow resistance than the replaced cyclone cell.

8. A method of producing a group of cyclone cells for a multicell cyclone, wherein each cyclone cell is comprised of structural elements, said method comprising forming at least a portion of the structural elements of the cyclone cells of the group in one piece as a single component such that said single component comprises all structural elements of like type of all the cells of the group.

9. A method according to claim 8, wherein the structural elements of like type of the cyclone cells of the group are formed in one piece by injection molding.

10. A method according to claim 8, wherein one of said components is a base body comprising intakes through which the fluid to be cleaned passes, and another of said components is an attachment body comprising outlets and center tubes for separating cleaned fluid from contaminant particles.

11. A method according to claim 10, wherein guide vanes of the cyclone cells are formed in the base body free from undercuts in a direction of fluid flow from the inlets to the outlets.

12. A method according to claim 10, wherein the base body and the attachment body are assembled to form a module comprising a group of cyclone cells;

said module being provided with a module housing that forms a collection chamber for separated particles, and said collection chamber having at least one opening to a channel structure for discharging separated particles.
