SUMMARY OF THE INVENTION: A hydrocyclone includes a cylinder-conical housing in which magnetic and pole elements are placed. The shape of the pole elements made in the form of triangular prisms provides a gradual increase in the magnetic field strength along the housing. 3 ill.

Description

The invention relates to devices for purifying liquids from ferromagnetic inclusions and can be used in the chemical and oil industries:

It is an object of the invention to increase the efficiency of the separation process. By means of increasing the magnetic field strength along the axis of the housing.

In FIG. 1 is a diagram of a magnetic hydrocyclone; in FIG. 2 is a section AA in FIG. 1; in FIG. 3 - the relative position of the clay and pole elements in a perspective view.

A magnetic hydrocyclone consists of a cylindrical L1 / ndroconic body 1 made of non-magnetic material, and magnetic 2 and pole 3 elements are placed inside of it. Each pair of pole elements 3 and the magnetic element 2 enclosed between them are located between the protrusions 4 of the cylindrical part of the housing. The magnetic system is closed from above by a non-magnetic cover 5. The fluid to be cleaned is supplied through the inlet pipe 6. The cleaned liquid is discharged through the outlet pipe 7. And the iron connections through the pipe 8. The pole elements 3 are made in the form of prisms, the bases of which are facing triangles are at right angles to the flow, with the bases of the prisms adjacent to the magnetic elements 2 placed between them, and the smaller side faces of the prisms facing the conical part of the housing 1.6 magnetic systems, the phenomenon of transformation of magnetic induction is known

BiSiVB2S2,

where Br is magnetic induction on the surface of magnet 2 adjacent to pole 3:

Si is the contact area of magnet 2 and pole 3;

B2 - magnetic induction on the lateral edge of the polyanoid Z, facing the flow;

$ 2 - the area of the lateral edge of the pole 3, facing the stream.

Thus, the magnetic induction EH depends on the area 5g. Since the Pelicheing of the area S increases from top to bottom, therefore, the value of induction will increase from top to bottom, and hence the intensity of the magnetic field.

The magnetic elements 2 are magnetized in such a way that their neutral lines pass through the center of the housing.

Tmdrocyclone works as follows.

The cleaned stream enters through the inlet pipe 6. Solid particles, including ferromagnetic particles, are subjected to the micropipe connection 8 under the action of centrifugal and magnetic forces, and the purified liquid passes through the outlet pipe 7. Due to the smooth change in the magnetic field strength, the ferromagnetic particles are evenly distributed they are then crawled along the inner surface of the hydrocyclone without forming ferromagnetic clusters in the upper part of the housing 1, which impede the calculated operating mode of the hydrocyclone,

The feasibility of using a hydrocyclone is achieved by increasing the degree of purification from iron compounds.
