Description

Description of the invention

The useful model refers to devices for cleaning liquids, in particular water, using the effect of a magnetic 2 field. The useful model can be used in the design of a magnetic sludge separator designed to retain impurities contained in water in the form of a solid phase and suspensions (magnetic sludge).

A magnetic filter-precipitator (sludge separator) was selected as a prototype. (Certificate for utility model of the Russian Federation Mo12122, published on December 16, 1999). The device has a case closed with a cover.

The body is equipped with inlet and outlet nozzles located radially along one axis. In the lower part 70 of the case there is an intermediate sieve bottom, in the lower part there is a blow-out nozzle. In the inner volume of the case, an insert is installed, made up of vertically oriented partitions. One of the partitions, located near the outlet nozzle, is longitudinal relative to the axis of the inlet and outlet nozzles. The liner also has two pairs of transverse baffles located near the inlet nozzle. These partitions are oriented perpendicular to the longitudinal partition. Each pair consists of two partitions located opposite 719 to each other, while the pairs are mirror-image to the longitudinal partition. Permanent magnets are attached to the mentioned partitions. On pairs of oppositely located partitions, magnets are fixed on oppositely oriented surfaces facing each other, and on a longitudinal partition, magnets are located on the side of the outlet nozzle on both of its surfaces in coaxial pairs. The insert also includes a vertically oriented partition (plate) without magnets. This plate is perpendicular to the longitudinal partition and separates it from pairs of transverse partitions. When the treated liquid passes through the filter, solid particles of sludge settle on permanent magnets and create agglomerates, which, upon reaching a certain mass, separate and fall to the bottom and are removed through the blow-out nozzle. The main disadvantage of the prototype is the lack of a given orientation of the magnets. If the magnets are oriented arbitrarily, the filter performs cleaning insufficiently efficiently.

The basis of a useful model is the task of increasing the degree of purification of the treated liquid, i.e. increasing the mass of particles of pollutants that are removed.

The task is solved in the following way.

The magnetic precipitator includes a housing with a blow-out nozzle and a cover, as well as inlet and outlet nozzles located radially on opposite sides of the housing. The body has an intermediate screen on the bottom and an insert made of vertically oriented partitions. The insert consists of a longitudinal "-- partition oriented along the axis of the outlet nozzle, as well as two pairs of partitions, each of which consists of two partitions located opposite to each other and oriented perpendicularly to the longitudinal partition. Pairs are mirrored relative to the longitudinal partition. Permanent magnets are fixed on the mentioned partitions, while on pairs of oppositely located partitions, magnets 3o are fixed on oppositely oriented surfaces facing each other, and on the longitudinal partition, magnets are located on the side of the outlet nozzle on both of its surfaces in coaxial pairs. The insert has a vertically oriented plate, perpendicular to the longitudinal partition and separating its part with magnets from pairs of oppositely located partitions. The device differs from the prototype in that on each partition the adjacent magnets are fixed with opposite poles. Magnets on the longitudinal partition, located opposite each other C 0, are closed to the partition by opposite poles, and on each pair of oppositely placed partitions c magnets, located opposite each other, are also oriented to each other by opposite poles.

From" The useful model is illustrated by Figures, which show: Fig. 1 - longitudinal section of the precipitator filter,

Fig. 2 - cross section AA, Fig. 3 - diagram of the location of magnets (longitudinal), Fig. 4 - diagram of the location of magnets (transverse).

The magnetic filter-precipitator has a cylindrical body 1, which is connected by means of a flange connection - to a cover 2. The body is equipped with an inlet pipe C and an outlet pipe 4 for the entry and exit of liquid, which 4! can be cleaned, as well as a blow-out nozzle 5 for removing dirt settled at the bottom. The inlet and outlet nozzles are located radially in the upper part of the housing diametrically opposite on the same axis. However, there is a possible version when the nozzles are made at different heights (their axes are parallel). A filter b is installed at the input of the output -k 70 nozzle 4. An intermediate sieve bottom 7 is fixed in the lower part of the housing. In the inner volume of the housing above the sieve bottom is installed an insert made of vertically c" oriented partitions. The longitudinal partition 8 is oriented along the axis of the outlet nozzle (along the common axis of the inlet and outlet nozzles). The insert also includes transverse partitions 9. There are two pairs of these partitions, each of which consists of two partitions located opposite to each other, and oriented 25 perpendicular to the longitudinal partition, while the pairs are mirrored relative to the longitudinal c partition 8. Partitions 9, located closer to the inlet nozzle, connected to the longitudinal partition, and the partitions opposite to them reach the walls of the case, forming part of the labyrinth for the passage of the processed liquid. Permanent magnets 10 are fixed on each partition 8, 9 - one vertical row on the partition. The distance between adjacent magnets in a row is the same and adjacent magnets are fixed on the partition by 60 different poles. At the same time, on pairs of oppositely located partitions 9, magnets 10 are fixed on oppositely oriented surfaces facing each other. On the longitudinal partition 8, magnets 10 are located on the side of the outlet nozzle on its two surfaces in coaxial pairs, that is, the magnets on the opposite sides of the partition are fixed in pairs at the same height. Coaxial magnets (located at the same level) on the longitudinal partition 8 are closed to the partition by opposite poles, and on each pair of oppositely placed partitions 9 magnets, located opposite each other, are also oriented to each other by opposite poles. The insert also has another transverse partition without magnets. This is a vertically oriented plate 11, perpendicular to the longitudinal partition 8 and separating its part with magnets from pairs of transverse partitions. Thus, partitions 8, 9 and plate 11 form a labyrinth for the passage of the processed liquid.

The device works as follows. When liquid enters the labyrinth channels between the partitions of the housing, its braking occurs. Part of the suspended particles during speed quenching under the influence of gravity settles on the intermediate sieve bottom 7 or sinks to the bottom of the housing. Smaller particles with paramagnetic properties are magnetized by the fields of permanent magnets, settle on their surface and create /o agglomerates, which periodically separate from the magnets and fall to the bottom due to the increase in mass. The above-described construction of labyrinth channels and the organization of magnetic fields allows to increase the degree of purification of the treated liquid, that is, to increase the mass of the particles of impurities that are removed by 5-1095.

The outlet nozzle is additionally protected by a mesh filter b with a developed active surface, which is able to catch non-magnetic particles of pollution.
