Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for separating ferromagnetic materials from a fluid medium. This equipment is used in chemical industry, heat power and technology industry.
For separating corrosion products, abrasion, crushed scale, etc. from e.g. ammonia, ammonia liquid, alkalis, concentrated liquids, circulating water, oil, steam and other fluids in the grinding industry, metallurgical industry, etc. can be used mainly in the form of a microfilter.

Various devices known as magnetic filters or di-gas separators are known that are used as fine filters to remove ferromagnetic particles from fluids.

Such a device is known to have a cylindrical housing containing two chambers, the one of the two chambers filled with a ferromagnetic overbanking being contained within a solenoid-like magnetizing element. Yes (Soviet Union Inventor Certificate I 6)
(See No. 98658 Akira Blind). A disadvantage of this known device is that there are severe demands on the winding MK of the magnetization system. This is because the diameter of each turn of the solenoid is at least equal to the outer diameter of the nozzle.

Other devices are also known with at least five or six chambers fixed to a common base in a virtual circle (see USSR Inventor's Certificate No. 784,894). ferromagnetic material p
An electromagnetic car is inserted between the overfilled chambers. These magnets have a straight core that contacts a soft magnetic plate attached to the wall of the chamber. The electromagnets are arranged alternately with chambers filled with filter material to form a circular closed magnetic circuit.

The disadvantage of this device is its poor maneuverability.

Namely, 2gxK, due to the multiple chambers present, this device is primarily suitable for treating large drops, and since the magnetic circuit is common to all chambers, it is not possible to separate the separate chambers. The only thing that can be done is to obtain economic benefits. Therefore, it is not possible to save power in this case (3. Since the magnetic circuit is common to all chambers, it is not possible to regenerate the backing in some chambers during Therefore, in order to regenerate the backing, the equipment must be shut down, making continuous filtration impossible.Secondly, conventional equipment uses windings to This makes it impossible to use in an explosive environment, such as an ammonia plant.It would be difficult to use an explosion-proof permanent magnet configured to periodically interrupt the magnetic flux passing through the backing.

The present invention makes it suitable for handling sinks of various industrial plant forces, and allows for continuous flow and operation in explosive environments without resorting to special equipment. The objective is to obtain a device for separating ferromagnetic materials from a fluid medium, which allows flexibility in the design and operation of industrial plants.

The purpose is to produce a ferromagnetic material from a fluid medium, incorporating a stationary chamber with a pipe for entering the fluid medium and a pipe for ejecting the fluid medium, and containing a ferromagnetic particle backing inside which can be magnetized. In the separating device, each pair of chambers is provided with a separate magnetizing element, the magnetic circuit of the magnetizing element comprising two parts arranged oppositely on either side of a straight line passing through the center of the chambers, and a pole piece; Each part is grooved with a magnet, and the pole pieces are arranged at opposite ends of a line perpendicular to the centerline, such that the two parts together with the ferromagnetic filtering backing of the chamber form a closed magnetic circuit. This is achieved by a device for separating the ferromagnetic material from the fluid medium, which is located next to the chamber.

For applications where there is a risk of explosion or power outage,
Conveniently, the permanent magnet is incorporated into the excitation circuit of the magnetizer, coupled to the pole piece, and provision is made to disconnect the permanent magnet from the magnetic circuit so as to break the magnetic circuit and eliminate the magnetic field. In order to be able to disconnect the permanent magnets from the magnetic circuit, they may be provided with a mechanism for rotating them, for example on a horizontally moving trolley. The permanent magnets could be provided with a mechanism for moving them at right angles to the chamber. For this purpose, the coupling mass between the permanent magnet and the magnetic circuit can be curved (cylindrical or conical) or flat. Mounting can be done using ferromagnetic inserts that are inserted between and fixed to the permanent magnets. The permanent magnet does not separate from the magnetic circuit. Mechanical shocks applied to the connection point between the permanent magnet and the magnetic circuit can be avoided by attaching a piece of ferromagnetic material to the magnet.

For explosion-proof applications, ie, when electromagnets and other electrical equipment can be placed in explosion-proof enclosures, it is convenient to wind the magnetizing device and integrate it into the magnetic circuit.

In order to use the device of the invention for continuous filtration, each of the two chambers is provided with a transverse partition, dividing each chamber into two spaces, each space provided with an inlet and an outlet, and a magnetizing device is attached to the chamber. The magnetization device is provided with a drive mechanism for reciprocating along the magnetization device.

The ends of the magnetic circuit that are coupled to the walls of the chamber can be flattened. It is also possible to give the ends of the magnetic circuit a curved shape, preferably cylindrical, by providing, for example, cylindrical depressions in the ends of the magnets or pole pieces or in the walls of the chamber.
It can be done.

In order to magnetize as much of the backing as possible, the opposing parts of the magnetizers located on both sides of the chamber are offset from each other so that instead of perpendicular magnetization, they are provided with so-called tangential magnetization.
n), that is, it is preferable to perform magnetization such that the lines of magnetic force form a parent bird with respect to a horizontal plane.

For cleaning large streams of fluid, or for cleaning several fluids with a specific composition before mixing, a number of It is convenient to use a chamber. The chambers can be arranged in a circle or a comb using a common substrate.

An advantage of the present invention is that each pair of chambers with a sensitizing device can operate as a full-featured device, thus increasing the functionality of the grout for separating ferromagnetic materials from fluid media. This means that, first, the device can process relatively small amounts of fluid using a pair of chambers, and clean significant amounts of fluid using a side pair of chambers located on the same substrate. means.

Second, to that end, it is possible to perform z4 filtration in one chamber pair sequentially from a plurality of chamber pairs in standby, so that the backing of one chamber pair can be regenerated while other chamber pairs are in operation. be. Third,! ! Easily processes several types of fluids with different compositions at once.
and that each pair of chambers can be easily adjusted to process one fluid or the other. Fourth
In addition, the device includes a magnetization device (4,
It thus appears suitable for operation with a magnetizing device h1 using permanent magnets or a sensitizing device using electromagnets (for use in potentially explosive environments or in case of power outages). In either case, by moving the permanent stone or deactivating the electromagnet, the magnetic field can be easily removed from the area where the banking is present, thereby regenerating the bucking. Inserts and pieces made of ferromagnetic material are used to facilitate rotation or movement of the permanent magnet and to protect the permanent magnet from mechanical damage. Using these inserts and strips increases the reliability of the device.

Another advantage of the device of the invention is that the magnetizing device can be moved along the chamber. This allows for both the use of the same magnetizing device to magnetize the banking contained in the length of the chamber and the tangential magnetization of the backing (the volume of the strongly actuated backing, thus increasing).
It facilitates As a result, the flexibility and economy of the device is increased. The key point of the present invention is that by dividing each chamber into two separate spaces, one pair of spaces is operated while the other pair of spaces are paused for backing regeneration, and this operation and pause are constant. It is repeated every period.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the device of the invention in operation, ie, with the Kf&air circuit closed to generate a magnetic field that removes ferromagnetic particles from the fluid; 5. A part of the whole 'fL diagram is shown with a cutout. Figure 2 is the same as Figure 1.
It is a cross-sectional view along the -■ line. FIG. 3 shows the device shown in FIG. 1 with the magnetic circuit opened to reproduce f-overbacking.

The device of the invention has two identical stationary chambers 1.

Each chamber 1 has a housing 2 filled with a ferromagnetic backing 3. The backing 3 is composed of a ferromagnetic material having a spherical, strip-like or other shape. If the device is used as a particulate filter, the backing 3 must also have edible properties. Each pair of chambers is provided with a separate magnetization device 4. The magnetic circuit of this magnetizing device 4 is formed by two parts 5 placed opposite each other on either side of a line passing through the center of the chamber. those parts 50
The magnetic coupling between them should be done via a ferromagnetic backing 3 so that a magnetic circuit is set up.

Next, the structure of the magnetization device 40 portion will be explained in detail. Each section 5 has a permanent magnet 6 and a ferromagnetic end piece or pole piece 7. It goes without saying that stratified foundation stones are as good as solid permanent magnets. As can be seen, the pole pieces are of identical construction and are arranged in pairs at opposite ends of each chamber.

The pole piece 7 is coupled to the housing 2 of the chamber 1 by means of a circular recess 8 provided on the side of the pole piece 7;
and is fixed to the housing 2.

By providing a recess in the housing 2K of the chamber 1 and providing a protrusion corresponding to the recess on the magnetic pole piece, the magnetic pole piece 7 and the housing 2 can be coupled. A pipe 9 for feeding the fluid to be treated into the device and a pipe IO for discharging the treated fluid from the device are provided in the chamber.

In order to switch from the operating state shown in FIGS. 1 and 2 to a state in which the backing is regenerated, the magnetic circuit should be interrupted by separating the permanent foundation stone 6 from the pole piece 7. For this purpose, the permanent foundation stone 6 can be taken from the pivot 11. The magnet 6 can be rotated by the pivot 11 as shown in FIG. The permanent magnet 6 can be rotated manually or mechanically. FIG. 3 shows the magnet 6 rotated relative to Y and thus cut off from the pole piece 7. When the magnet 6 is rotated in this manner, the magnetic field disappears, and the device enters a knocking regeneration state.

FIG. 4 shows another embodiment of the device according to the invention in the regeneration state. This embodiment uses a special trolley (not shown) K with permanent magnets 6 configured to move along a rail (not shown) K perpendicular to a line passing through the center of the chamber 1.
The construction is almost the same as that of the embodiments shown in Nos. 1 to 3M, except that it is attached. When the magnet is moved in this manner by the trolley, the magnetic circuit is closed or opened, and the device enters the operating state or regeneration state, respectively.

5 and 6 are cross-sectional views of another embodiment of the arsenizing device 4, which is easier to use than the magnetizing device 4 shown in FIGS.

Referring first to FIG. 5, the magnetizing device 4 has two opposing parts 5. Each part 5 includes two permanent magnets 12;
A ferromagnetic insert 13 is sandwiched between these permanent magnets 2. As the permanent magnet 12, a stratified permanent magnet can also be used. The inserter) 13 is fixed to the permanent magnet 12.

A rotation mechanism (south not shown) for moving the magnet 12 is attached to the inserter 1-13 (see Figures 1 and 3). magnet! The ferromagnetic piece 14 fixed to the end face of the magnetic pole piece 1
7 to prevent the magnet from being worn out. Part 12
The rotation or movement of the assembly consisting of parts 14 to 14 with respect to the pole piece 7 takes place in the same manner as shown in FIGS. 3 and 4.

The sensitizing device used in the embodiment shown in FIG. 6 includes the same elements as the embodiment shown in FIG. However, the method of assembling these elements is different from that in the embodiment shown in FIG.
, [ru. The facing part 15 of the magnetizing device 16 is the permanent magnet 1
Contains 7. The permanent magnets 17 are arranged next to the housing 20 of the chamber 1 and are separated from each other by an extending ferromagnetic insert 18. A ferromagnetic piece 19 is attached to the end of the permanent magnet 17 facing the housing 2. These ferromagnetic pieces 19 are coupled in such a way that the pole piece 20 can be divided. Part 17 shown in Figure 6
The movement of the assembly comprising ~19 relative to the pole piece 20 is
This is done in the same manner as shown in FIGS.

The movable assembly shown in Figures 1-6 of the sensitizing device with permanent magnets makes the device suitable for use in a variety of environments, including explosive atmospheres. Furthermore, the backing can be completely regenerated after a period of time by rotating or moving an assembly to remove the backing from the magnetizing field.

FIGS. 7 and 8 show still another embodiment of the apparatus of the present invention. In this embodiment, the facing portion 22 of the magnetizing device 21
is composed of an iron core 24 and a winding 23 attached to this iron core. Winding 23 is connected to a power source.

Although the core is shown as being integral with the pole piece, this does not mean that the two parts are inseparable.

FIG. 9 shows yet another embodiment of the apparatus of the present invention. In this embodiment, a chamber IK partition 25 is provided. This partition 25 divides the chamber 1 into two spaces 26, 27 each provided with a fluid intake and an outlet. For example, the magnetizing device 21 shown in FIGS. 7 and 8 is configured to be moved along the chamber by an electric motor 28 and gear wheels.

This arrangement allows the backing in the lower space 27 to be regenerated while the upper space 26 is in operation, or vice versa, by properly positioning the magnetizing device.

FIG. 10 shows yet another embodiment of the apparatus of the present invention. In this embodiment, the part 22 of the sensitizing device shown for example in FIGS. 7 and 8 is moved relative to the chamber IK so as to tangentially arsenize the backing 3.

As long as the device of the invention is in operation, the ferromagnetic particles enter the chamber through the pipe 9 and are separated from the fluid flowing through the magnetized overbacking 3, and then the fluid is released from the chamber. The direction in which the fluid flows is indicated by an arrow in the diagram. To regenerate the backing, the fluid flow to the chamber must be cut off and permanent magnets 6 (Figs. 1-4) or 12 (Fig. 5) k or 17 (6
(Fig.) can be rotated or moved. Alternatively, the two parts 22 (FIGS. 7-10) of the magnetizer are de-energized. The backing was then able to magnetically attract the ferromagnetic material. By washing the precipitate out of the device, the device can be operated again.

Although the present invention has been described above with reference to four embodiments, it will be obvious to those of ordinary skill in the art that various modifications can be made to the embodiments thereof without departing from the gist of the present invention. For example, it is possible to construct a device comprising multiple pairs of chambers with individual magnetization devices disposed on the same substrate and with outlet vibes connected to a common manifold.
