Description

The invention relates to the filtration and purification of liquid and gaseous media and can be used to separate the medium into fractions.

The purpose of the invention is to increase the reliability of the device and its service life.

FIG. 1 shows the proposed device, the cut; in fig. 2 - torus with screw-like twisted inner walls, section.

The device consists of a closed 1 -pipe 1, communicated with the means 2 for supplying the contaminated medium and the collection 3 of the purified medium. Shells 4, made in the form of a torus 5 and filled with filtering granular material 6, are placed in the housing 1; the inner walls 7 of each torus are screw-wound with respect to the diametral axis of the mesh sheath. Case 1 is separated by valves 8 and

9 on the filtration chamber 10, the washing chamber 11, while the means 2 for supplying the polluted medium are installed in the filtration chamber

10 before the reinforcement 8, and the means for supplying the washing medium 12 with a diametrically located collector 13 for removing the contaminated medium 13 are installed between the reinforcement 8 and 9 in the washing chamber. The shut-off valve 9 is installed in front of the collection of purified medium 3.

The tori 5 are made of a tubular mesh material of constant diameter by inverting one end of the tube outward and connecting with the other end. Before connecting the ends of the tori 5, their inner walls 7 are twisted for the required number of revolutions, and the internal cavity to9s ate

The ditch is filled with filtering granular material 6.

The device works as follows.

Polluted medium is fed into housing 1, which begins to move the tori. The tori 5, rolling, move in chamber 11. The medium passes through the tori 5 and is cleared of sediment retaining in them. When the torus 5 enters the chamber 11, the means 12 supply the washing medium to the torus 5, which is washed. Sludge enters collection 13.

After washing the torus 5, it enters the filtration chamber 10, the cycle repeats.

The technical and economic efficiency of the proposed device as compared with the prototype device is achieved by means of helically twisted inner walls of 7 tori and completely eliminating the leakage of the uncleaned medium through the tori. In this case, a more uniform wear of the mesh material of the tori is achieved, which makes it possible to increase the service life of the device.
