The invention relates to mechanical engineering, namely to centrifugal engineering, and can be used in the processing of zeolite raw materials to produce sodium, potassium, calcium-hydrogen forms of zeolites for the national economy.

A known centrifuge comprising a housing with a collection of target products, media inlet and outlet pipes, a drive shaft, upper and lower disks mounted on it, a non-rigid perforated partition (NPC) placed between them, and a source of vibration accelerations.

In the known centrifuge, vibrational accelerations are generated by unbalanced sediment masses located on the NFP, which makes it difficult to use them for clarification of low-concentration races. creators.

A known centrifuge containing a housing with collections of target products, nozzles for supplying and discharging media, a drive

a shaft, upper and lower disks mounted on it, a NPP placed between them and a source of vibrational accelerations.

In the prior art centrifuge, NPPs communicate by hydraulic shocks to the separation of the medium, and this makes it difficult to control the separation process without affecting the performance of the centrifuge.

The goal is to provide a wide range of regulation of the intensity of the vibrations.

This is achieved by the fact that in a centrifuge containing a housing with collections of target products, nozzles for supplying and discharging media, a drive shaft, upper and lower disks mounted on it, a NPC placed between them and a source of vibration accelerations, according to the invention, the source of vibration accelerations is made in the form a tubular collector placed along the generatrix of the NPP, equipped with a tangential outlet, at XI

- Message vibrations NPP due to sweat. as a clarified liquid, the amount of which, regardless of productivity, due to repeated use, provides a wide range of vibration control. At the same time, the supply of clarified liquid to the gap between the cards allows the sediment to be moved and the filtering properties of the NPP to be restored. An annular gap overlapped by the collector between the NRP and the clarified liquid collector allows the use of an air-liquid spray stream for additional generation of NRP oscillations and its regeneration. All together, creates a wide range of regulation of the intensity of the oscillations. ;,:

The centrifuge contains a housing 1 with a collector of clarified liquid 2 and a nozzle 3 of its outlet, a nozzle A for supplying the medium to the separation, a drive shaft A. 5, mounted on it are the upper 6 and lower 7 discs, located between the NPP 8: and a source of vibration accelerations, which is made in the form of a tubular collector 9, placed along the generatrix of the NPP 8, provided with a tangential outlet 10, for example, in the direction opposite to the direction of rotation of the NPP, into the gaps 11 between the cards of the latter, and the slotted outlet 10 of the collector 9 overlap there is an annular gap 12 between NPP 8 and the clarified liquid collector 2, Collector 9 is in communication with a ring inlet 13, and the upper disk 6 is mounted on a rack 14 made with windows 15. A drying cavity 17 is located concentrically to the discharge edge 16 of NPP 8, communicated with blast chambers 18..

The centrifuge operates as follows. . ...; . . ; . .. ..:, .. -.;. ..

After activation of the sodium, potassium, calcium-hydrogen forms of zeolites, the mixture decantation is separated from the spent

chloride and hydrochloric acid solution. The spent solution through the pipe 4 enters one hundred to 14, and from it through the windows 15 is discharged to the NPP 8, where the clarified liquid

It is separated and removed from the collection vessel 2, and the suspended zeolite particles are moved upward and discharged through the discharge edge 16 into the drying cavity 17, where they are treated with the heat carrier from the blast chambers 18 and are used as a commercial product in the form of powder or granules. A portion of the clarified liquid is pumped (not shown) into an annular inlet

13, and from it to the collectors 9 and through slotted,

tangential issues 10 are thrown onto the runway 8 and into the gaps 11 between the cards of the latter, generating oscillation. When the rotation of the NPP 8 in the annular gap 12 there is a vortex flow of air-liquid

mixture, which upon impact on the slotted tangential outlet of TO is discarded to NPP 8 additionally creating its oscillations with a deep degree of concentrated sediment before drying, which reduces consumption

energy to abrasion.

The technical and economic effect consists in the fact that the resulting finely ground zeolite has a large reaction surface and a uniform

structure, which ensures its use, for example, in medicine.
