Description

one

The invention relates to mixing grinding devices used. mainly in the cementing of oil and gas wells, as well as in construction work ,.

A continuous flow mixer is known, in which the source of rotating electromagnetic fields is made in successively three-phase alternating current alternating current electrodes (Q) alternating along the mixing chamber, which create magnetic fields with opposite direction of rotation in the adjacent zones of the chamber.

In such a mixer, at the entrance from the electromagnetic zones, the gratings are installed, which impede the entrainment of ferromagnetic elements. However, the grids create additional hydraulic resistances, which reduce the efficiency of the mixer in operation. In addition, due to the clogging of the gratings by the components of the solutions and ferromagnetic elements, it is necessary to periodically stop its operation and clean the gratings.

The closest technical solution is a mixer comprising a non-magnetic 25

a body with a mixing chamber and ferromagnetic elements placed in it, ring electromagnets and linear indicators,. installed outside of the body along with electromagnetic fields that create rotating and running, and fittings for the input and output of materials 21.

However, this mixer does not provide a sufficiently effective mixing and halogenation of the materials being processed.

. In order to intensify the processes of mixing and dispersion, linear inductors are arranged in an alternating sequence between ring electromagnets with the direction of a traveling electromagnetic field towards the nozzles of the input materials.

The drawing shows the mixer, a longitudinal section.

The mixer has a non-magnetic housing 1 of the mixing chamber 2 and ferromagnetic elements (not shown in the drawing), ring electromagnets 3 and linear inductors 4 installed outside the body and creating rotating and traveling electromagnetic fields, and fittings 5 n 6. input and output materials accordingly. Linear inductors 4 are located in the continuous sequence between ring electromagnets 3 with the direction of a traveling electromagnetic field in the direction of the unions 5 input materials. Ferromagnetic elements can be made of magnetostrictive material, for example an alloy of Alfer. The mixer operates as follows: Ferromagnetic elements are inserted into the mixing chamber 2 through nozzles 5; for example, a wire made of ferromagnetic material is cut into pieces. Then, components that need to be nepeMeuiaTb and crushed {imentoment, water and T, fl,) are passed through the displacement chamber. At the same time, the annular electromagnet creating an oppositely rotating electromagnetic field is put into operation. Ferromagnetic elements coming into motion are intensely affected by the components that are passed through the mixing chamber — they are mixed and ground. When moving ferromagnetic elements, some of them fall into the central part of the mixing chamber, where the speed of movement of the components is maximum and the magnetic forces holding the ferromagnetic elements are minimal. To prevent the ferromagnetic materials from escaping from the action of rotating magnetic fields together with ring electromagnets, they linear inductors. They create a running electromic field that is directed to the side (shown by arrows at the walls of the chamber) against the movement of comonents (indicated by arrows: AXIS camera). Therefore, the ferromagnetic elements carried away by the components from the zone of action of the ring electromagnets are returned back and there is no need to pass the grids. Due to the absence of gratings in the mixing chamber, the effect of rotation and flow turbulization, achieved as a result of a change in the direction of rotation of the ferromagnetic elements, is enhanced, which contributes to the increase in the effect of mixing and dispersion. Along with this, an electromagnetic inductor additionally activates the components with its field and is returned to meromagnetic electromagnetic elements. The ferromagnetic elements (rods) are proposed to be made of a magnetostrictive material of alphers, which changes its shape and size under the action of an external magnetic field. They create near pulsed mechanical and hydrodynamic effects on the components, further intensifying their mixing and dispersion. The use of the proposed device according to calculations will allow to reduce hydraulic resistance by 20-25%, increase efficiency by 10-15% and increase the efficiency of the mixer in operation by 30-40%; Formula invented.

In that, with the integration of the processes of mixing and dispersion, the inline inducers are arranged in an alternating sequence between ring electromagnets with the direction 6eryuiero of the electromagnetic field towards the nozzles of the input materials.
