Description

(54) CYCLONE

I

The invention relates to the T) cleaning of liquids and gases from suspended particles and can be used in communal households, building, metallurgical, mining, chemical and other industries.

A cyclone is known, which includes a cylindrical housing with a tangential feed. IM pipe, drain and sludge pipe. An electromagnetic coil is installed on the slurry pipe {.

The disadvantage of this device is a high abrasive wear of the slurry pipe.

Also known is a cyclone comprising a housing with inlet and outlet nozzles, a louvered conical element with swivel plates and a filter mounted concentrically with a helical guide and a solenoid tZ.

The disadvantages of this cyclone - the complexity of the design and significant abrasive wear of all elements of the device.

The closest to the invention to the technical essence and the achieved result is a cyclone comprising a cylindrical body with a tangential supply nozzle, a drain and sludge nozzle and an electromagnet, the coil of which is installed outside the cylindrical part of the body 3.

A disadvantage of the known device is also high abrasive wear of the casing walls.

The purpose of the invention is to reduce the abrasive wear of the casing walls and to increase the cleaning efficiency by increasing the speed of the swirling flow.

The goal is achieved by the fact that the cyclone is provided with a spring-loaded cylindrical bushing with an elastic coating having annular acute-angle protrusions, the sleeve being placed inside the body and made of a ferromagnetic material, and the body is made of a non-magnetic material.

With longitudinal vibrations of the sleeve under the action of a pulsed magnetic field created by an electromagnet coil, acceleration directed along the cyclone axis is transmitted to suspended particles in the peripheral part of the body, which increases the steepness of the particle trajectories and, as a result, reduces the abrasive wear of the cyclone body. Figure 1 shows a schematic of a cyclone, a general view. The cyclone has a cylindrical body 1 of non-magnetic; 1-o material and a supply nozzle 2 located tangentially in the upper part of the body. On the cyclone body there is an electromagnet coil 3 which is held from below by the body 4. The purified liquid or gas is discharged from the cyclone through the drain nipple 5. Inside the body there is a cylindrical sleeve 6 made of ferromagnetic material, spring-loaded with compression springs 7. Inside the sleeve has a coating 8 of elastic material, such as rubber. The coating has annular acute-angled protrusions (antennae) 9. The cyclone operates as follows. The medium (liquid or gas) that is to be removed from the suspended particles is fed into the cyclone tangentially through the supply nozzle 2, where the medium acquires a vigorous motion, while suspended particles with a density greater than the density of the medium, under the action of centrifugal forces are thrown down to the cyclone body and slide down, fall into housing 4 and discharged therefrom through the sludge port. When an impulse voltage is applied to the coil 3 of the electric clutch, a pulsed magnetic field arises which causes the sleeve 6 to oscillate. The sleeve 6 moves downward under the action of the magnetic field of the coil 3, and the backward movement upwards under the action of the compression springs 7. When moving, the sleeves 6 upwards tendrils 9 of the elastic coating 8 are pressed inwards and the medium is practically not captured, and when the sleeves move downwards, the reinforcement retreats to the cyclone's axis, and they pick up the near-wall layer of the medium most saturated with suspended particles. And cast the era down. Due to this, the particles acquire a longitudinal acceleration directed downward and move along steep trajectories m. Reducing the abrasive wear of the cyclone body and the sleeve is due to the fact that the suspended particles draw a shorter trace while reducing the force effect of the particles on the body. In addition, the oscillatory movements of the sleeve help to reduce the friction of the medium against the walls of the housing, which increases the rate of swirling flow and cleaning efficiency. All this allows to increase the performance of the cyclone, the degree of cleaning and the service life of the body. Claims of the Invention Cyclone comprising a cylindrical housing with a tangential supply pipe, a drain and sludge pipe and an electromagnet whose coil is installed outside the cylindrical part of the body, characterized in it is equipped with a spring-loaded cylindrical sleeve with an elastic coating having annular acute-angle protrusions, while the sleeve is placed inside the housing and you It is made of ferromagnetic material, and the body is made of non-magnetic material.
