Centrifugal separator device with at least two centrifugal separators

The innovation relates to a centrifugal separator device with at least two centrifugal separators with a tangential inlet. of the uncleaned accept and the central outlet of the coarse material, which is headed first through an inlet chamber into a adjoining drainage chamber are inserted as a whole and interchangeably, so that they contain uncleaned accepts, e.g. a suspension for papermaking, from the inlet chamber and can deliver cleaned accepts into the outlet chamber while their coarse material outlet protrudes from the inlet chamber.

Centrifugal separators are also known as cyclones, vortex separators, pipe centrifuges, cone centrifuges and centrifugal cleaners known.

In one known from the German utility model 1,932,636 Centrifugal separator devices of the type mentioned are the inlet and drain chambers formed in a common header which would normally be a casting. Such one-piece chamber housing can only be economical with small designs getting produced.

In a centrifugal separator device known from DT-PS 1 5I7 9 ^ 5 with several centrifugal separators is the conical housing of the hydrocyclone with the bottom of the inlet chamber below connected, while the central guide tubes through this

Inlet chamber protrude and at the bottom of the overlying Drain chamber are attached. But this means a replacement entire cyclones or centrifugal separators not possible,

The object is to be achieved by the innovation in a centrifugal separator device of the type mentioned at the outset, technically simple and economically inexpensive, even for larger embodiments to create a three-dimensional shape to be executed, these properties also being given in particular at high chamber pressures.

This object is achieved according to the innovation in that the two Chambers of two interconnected, arranged parallel to one another elongated bodies are formed.

Several exemplary embodiments of the three-dimensional shape according to the innovation are shown in 1 to the drawings and will be described below with reference to them. Show of it

Fig. 11 shows a three-dimensional shape according to the innovation similar to Figures 1 and 5, but in which the drainage chamber with a Vacuum connection is provided.

In the centrifugal separator device according to FIG. 1, there are cone centrifuges 1 inserted from below through the body 2 of an inlet chamber into the body 3 of an outlet chamber and releasably fixed. Instead of a plug connection, a screw connection can also be used. The elongated body 2 of the inlet chamber is provided at one end with an inlet 4, and the elongated body 3 of the drainage chamber is provided at its end remote from it a drain 5 provided. The ones from bodies 2 and 3 down Outstanding coarse material outlets 6 of the cone spinners 1 are connected to a reject line 7.

In Pig. 1, for the sake of simplicity, only one cone sling 1 is shown, but in reality there are several such cone slingers 1 arranged in a row one behind the other over the entire length of the body 2 and 3.

As can be seen in particular from FIG. 2, the two bodies 2 and 3 consist of sheet metal cylinders, of which the lower cylinder cut open at the top over its entire length and the upper cylindrical body 3 into this cut-out opening = is set and thus protrudes somewhat into the inlet chamber. The two bodies 2 and 3 are at their extending in the longitudinal direction Contact lines at 8 and 9 welded together. The openings in the lower body that serve to accommodate the cone sling 1 2 are denoted by 10 and those of the upper body 3 are denoted by 11.

Fig. 3 shows a similar three-dimensional shape according to the invention, but in which the body 3 of the drainage chamber one over its entire length running opening and designed as a closed cylinder Body 2 of the inlet chamber extends into this opening.

In the modified three-dimensional shape according to FIG. 4, the two bodies are 2 and 3 of the inlet and outlet chambers via spacer elements 12 with one another tied together. Otherwise, this three-dimensional shape is designed in the same way as the three-dimensional shape described with reference to FIG. 1.

The three-dimensional shapes according to FIGS. 5 * 6, 7 and 8 correspond to each other those of Figures 1, 2, 3 and 4, with the exception that these have two rows of centrifugal separators 1 instead of a single row. Corresponding parts are therefore given the same reference numbers and will not be used again described.

As FIG. 9 shows, the three-dimensional shape according to FIG. 8 and in the same way Catfish also has the three-dimensional shape according to Fig. 4, ^ ines or several steel bands 13, with which the two of them learn about the distance 12 separate bodies 2 and 3 are connected to one another.

Fig. 10 shows a «, ^{1 of} the pig. 5 similar rauro shape according to the innovation, in which, however, the body 14 forming the inlet chamber tapers conically from its end provided with the inlet 4, while the body 15 of the outlet chamber sitting on it widens conically complementarily to its end provided with the outlet 5 . Since a larger amount of substance can be present in the chambers of the two bodies 14 and 15 in the area of the inlet 2 and the outlet 5, this is an expedient measure to save material for the production of the two bodies 14 and 15 and to make the device so small train as possible.

In the three-dimensional shape according to the innovation according to Pig, 11, the essentially corresponds to that of FIG. 1, the container 3 forming the discharge chamber is provided with a vacuum connection 6. This is how it is possible to degas the substance to be cleaned at the same time.

The substance to be cleaned, usually a suspension, overflows the inlet 2 into the inlet chamber of the lower body 2 and then into the centrifugal separator 1, in the case of the three-dimensional shapes described here According to the innovation, for example, cone spinners that move the coarse material or rejects down into the rejects line 7 dispense while they move the accept upwards into the overlying one Enter the drain chamber of the body 2, from where it is withdrawn via the drain 5 will. This mode of operation is the same for all new room shapes. Depending on the use, in the feed chamber of the body 2, a greater pressure prevail than in the drainage chamber of the upper body 5. Furthermore, it is in each of those described Spatial forms are possible according to the innovation, that formed by the body Drain chamber with a vacuum connection 16 according to Pig. Il too provided in order to carry out a substance degassing.

According to the innovation, larger three-dimensional shapes, ie longer and / or larger bodies 2 and 3 in terms of cross-sectional area, for larger or larger numbers of centrifugal separators 1 can also be produced in a technically simple and economically inexpensive manner. Another advantage is that in the case of bodies 2 and 3, which are circular or polygonal in cross-section, relatively thin-walled sheet metal can be used as the jacket wall, even if high chamber pressures are used during operation.
