Definitions
- the quicker invention is supplied with gas filters and, more precisely, with magnetic filters.
- the product has shown that, for example, in the event of a loss of business or loss of business, it is the result of a loss of business or any other reason for loss of business.
- the microparticles located in the working area of the welder are 0.1–2.0 ⁇ m. These particles, in fact, contain a lot of foreign substances, such as manganese, ⁇ ⁇ other. Particles, falling through the human respiratory tract inside his body, cause its intoxication and various prudential diseases.
- Filters developed earlier for calculating the working area of the microparticles are based on the use of filter materials, or for the collection of microparticles. Most of the microparticles used in steelmaking, steelmaking and welding are equipped with magnetically impaired electrical components.

- the effective performance of the magnetic filter makes it possible to efficiently capture microparticles that have a magnetic effect, whether it is - 2 - the highest magnetic field strength.
- the gap between the magnet and the filter element is greatly reduced by the magnitude of the magnetic field by the filter; 5 is more This is true because the use of small magnets in the magnetic field is not possible.
- the filter element does not have a large voltage drop due to the magnetic field, which also does not lead to improvement.
- Increasing the efficiency of dust collection of a magnetic filter of such an efficient performance entails
- the main task of the invention was to create a magnetic filter, by changing the design of the filtering element it would ensure that it would not be damaged.
- the task is solved in that, in a magnetic filter, in a short-circuited short-circuit case, it is simply connected to a
- a large component of the magnetic component is used to increase the energy of the magnetic component, which is used to increase the energy of the filter.

- the filter element is connected to the magnets of the magnet by means of magnets that are magnetically and electrically charged to the magnets. This prevents the dissipation of magnetic energy and, thereby, increases the stress
- magnets be exposed to - 5 - are made from a material that has a small kerocitive force, which makes it easier to remove when magnet is removed, which makes it easier to
- the magnetic filter is designed to pick up magnetic particles and to count
- the in-line filter contains the housing I (Fig. I), which is shortened to 2. In addition to the housing I, it is in good condition.
- HAR filter element 3 For the area bib filter element 3 is installed for a smaller measure one magnet, in this case the magnetic filter is equipped with two magnets.
- the koltsy magnets ⁇ , ⁇ occidental are installed with the corresponding basic ⁇ - ⁇ ⁇ kruppusa I, so that they have the opposite effect. Ring magnets ' ⁇ réelle, ⁇ occidental are secured to magnets-
- the non-magnetizable filter element is equipped with concentrates of magnetic field voltages, separated by the whole of the connecting filter 13.
- Connector 2 is connected
- the small disks 22a, 23a were performed in a series of versions 27a, 27c, 27c, 27 ⁇ . ⁇ side wall 28 page - 7 - canal 17 was also performed on 29a, 29v.
- the internal area of 30 is 17 and it is reported that it is not in use (not indicated at all);
- the Magnetic Filter handles the following.
- the magnetic filter is installed in the area of the working place of the welder. Turns off the fans and drives the flexible drive
- a magnetic filter is discharged, in an enclosed roof 31 (Fig. 3), 32 housing, which is connected to the main drive, is attached to it and is completely electrically safe.
- the hollow, non-magnetizable filter element 33 is equipped with an energized, non-magnetically energized device.
- the filtering element 33 is made of the lavsan.
- Well 37 made from a material that has a small 9 kerocitivnoy by force, in this variant from sysututlero- steel.
- the neighboring rings 37a (Fig. 4), 37c have a different diameter. This makes the filter element 5 36 filter element 33 group-shaped, which, in turn, increases the vacuum level of the filter module and removes the filter by 33
- magnetic filters can be used successfully to clean the air in a convenient way. Otherwise, these magnetic filters can be used in metallurgical applications in the course of the execution of steel, steel smelters
