SU151969A1 - Electromagnetic separator for the regeneration of ferric ulnage from the drilling drilling fluid - Google Patents

Description

Electromagnetic separators are known for the regeneration of ferrous iron from the washing liquid.

The described electromagnetic separator differs from the known ones in that it consists of two disks concentrically mounted on the aluminum shaft, their disks immersed on Vs of diameter in the stream of advanced flushing fluid flowing along the groove and influenced by the magnetic field of the electromagnetic coil embedded in the common discs casing on the shaft parallel to the shaft of the disks. In addition, disks made of Armco-type iron consist of six sectors with grooves having a saw-tooth profile, which are filled with babbit, and the electromagnetic coil can be mounted directly on the disk shaft.

Such an implementation of an electromagnet ensures the regeneration of the aggregate at the place of production of drilling operations, which opens up the possibility of saving money.

FIG. 1 and 2 depict an electromagnetic separator, in two projections; in fig. 3 is a section along A-A (without tray) in FIG. one; in fig. 4- separator disc; in fig. 5 is a section along BB in FIG. four; in fig. 6 and 7 - a separator with an electromagnetic coil mounted on a shaft of disks in two projections.

The separator consists of an electromagnetic electromagnetic coil 1 of direct current, mounted on the shaft 2 (core), two concentric disks, 3, mounted on the aluminum shaft 4 and rotating with the latter in the support 5 with a handle 6 or

a motor (not shown in the drawing), a casing in the form of two cheeks 7 and a wooden chute 8. The disks 3 consist of six separate sectors 9 (see Figs. 4 and 5) made of Armco iron. Each sector is provided with grooves having sawtooth, which are filled with babbitt.

The recovery of the ut gel from the spent mud is carried out as follows.

The spent mud, moving in the tray, passes through the interdisk gaps, and the particles and zheltel, under the action of magnetic field lines, will be attracted to the inner surfaces of the disks, overcoming the forces of friction. The magnetic field in the air gap intersects the discs in 2/3 area, where the particles of uthelle, having attracted to the iron surface of the disc sector from the teeth, rise up during rotation. Then the same sector falls into the area (angle of 120 °), where the magnetic field does not act. Thus, in the sector of 120 °, the particles of the aggregate to the disks will be bu; 3, they are drawn in very weakly or completely disappear from the disk. The removal of these particles is carried out with brass scrapers. For separating non-magnetic impurities that may adhere to the surface of the disks under the action of surface attraction, forced washing is used. FIG. 5 and 6, an electromagnetic separator is depicted, which, by the principle of operation, is completely analogous to the operation of the separator shown in FIG. 1 and 2. It differs only in that the electromagnetic coil 1 is mounted on the shaft 2 of the disk 3.
