Description

I

The invention relates to the equipment of the chemical industry, in particular to devices for the purification of sludge water, and can be applied in the purification of liquid media containing magnetic particles,

Subsea water is used for hydrotransport of sludge and cannot be used in technology due to the high content of suspended matter (red mud). Subsea water, except for settling in the sludge field, is not subjected to other treatment, and simple settling and (} sludge due to the fine dispersion of the sludge is ineffective.

A known apparatus for thickening ferromagnetic suspensions, comprising cor-. the electromagnetic system, located on the outer side of the housing jc, is a loading, drain, and discharge pipe, a capillary grill of nonmag material material, and the grill is equipped with a height adjuster 1.

The disadvantages of the known apparatus are the difficulty in cleaning the purification; due to the content of large particles, as the lattice clogs. Sharp fluctuations in the suspension content in the cleaned fluid cause the same fluctuations in the suspension in the filtrate. In addition, the device is characterized by a short time of the motorcycle and the laborious work of washing the pill grid.

The purpose of the invention is to increase the cleaning efficiency and increase. time fit trotsikla.

15 what the body in the lower part is equipped with a magnetic coagulator with a nozzle of fi ro magnetic balls; and the wall of the expanded part of the housing is mounted with the possibility of vertical movement. The drawing shows schematically the apparatus, a common Vice, a vertical section. The device consists of a body I, the bottom 2 and top 3 of which are made of the same diameter, and the middle part is 4. expanded. The bottom 5 of the expanded part 4 is made cone-shaped with a hole 6 at the apex and rigidly fixed with the lower part 2, in which a magnetic coagulator 7 is installed, filled with ferromagnetic balls, and in the upper part 3 a grating 8 and nozzle 4 of ferromagnetic particles are fixed. On the outer side, the housing 1 in the upper and lower parts is equipped with an electromagnetic system 10. A conical trough 11 is rigidly attached to the cone-shaped bottom 5, which encloses the shell 12 of the middle extended part 4. The shell 12 is connected to the jacks 13, which carry out its vertical reversal: - placement. A sealing ring is fixed on the bottom 5, and a seal 14 is mounted between the wall of the annular gutter 11 and the shell 12. The housing 1 is equipped with nozzles for admitting the cleaned liquid 15 to discharge sediment in the lower part of the apparatus 16 to drain the bleached liquid 17 for washing apparatus 18. Position 19 indicates coagulated precipitate. The operation of the apparatus is carried out as follows. A liquid containing magnetic particles is fed into the housing 1 through the pipe 15 below the zone of action of the electromagnetic system 1O. Pipe 15 below the zone of action of the electromagnetic system 1O. Large particles (about 10–15%) under the action of gravity sink to the bottom of the bottom and, as they accumulate, are discharged through pipe 16, the remaining particles pass through the ball loading of the magnetic coagulator 7 and settle on the inclined bottom 5 of the media; 4 cases. The sedimentation of particles occurs due to a decrease in the velocity of flow in the middle part of the apparatus and due to the formation of small arperalOB from small particles, which under the action of gravity will quickly settle. The fine fraction itself, which did not coagulate (about .5%) was delayed by a magnetic nozzle 9 installed on the grid 8 in the iO i electromagnet zone, the clarified solution is discharged through the outlet nozzle 17. The coagulated sediment accumulated on the conical bottom 5 is removed from the middle part 4 in the following way. The shell 12 is lifted for a short time by means of jacks 13, and sediment is forced out of the liquid by pressure in the annular groove 11, after which the shell 12 is lowered onto the sealing ring, ensuring tightness. Turning on and off of jacks can be programmed. The introduction of the device provides savings for one plant about 1OO thousand, rubles. in year. Claim 1. An apparatus for cleaning liquids from ferromagnetic particles, comprising a housing, an electromagnetic system located outside the housing, a loading, a drain, and a discharge steam, characterized in that in order to increase cleaning efficiency and increase the time of the 4-cycle cycle, the housing B of the lower part is equipped a magnetic coagulator with a nozzle of ferromagnetic balls, the middle part of the body is made expanded and provided with a cone-shaped bottom with a hole in its top and a device for removing scoops of the world ocatiKa. 2. The apparatus according to claim 1, characterized by the fact that the device for removing or coagulating sediment is made in the form of an annular groove, covering the outside of the expanded part of the body, the cone-shaped bottom is rigidly connected to. the lower part of the body and with a ring chute, and the wall of the expanded part of the body is mounted with the possibility of vertical movement.
