Description

The invention relates to a technique for filtering liquids by filtration, can be used in chemical, metallurgical, engineering, paper, food and other industries to clean river, process and recycled water, waste oils and other liquids and is an improvement of the invention auth. No. 126330.1.

The purpose of the invention is to improve the performance and environmental cleanliness of the filter.

The drawing shows a self-cleaning filter, a general view, a slit,

The self-cleaning filter comprises a housing 1 with an inlet nozzle 2. Inside the housing 1, a filter partition 3 is installed coaxially with it, made in the form of a cylindrical shell with a mesh, attached to the lid 5 and the bottom 6 of housing 1 with its base 4 and bottom 6. made of sloping -membranes. The chamber 7 of the clarified liquid is formed by a filter septum 3. Inside its chamber 7, along its axis, a device is installed for regenerating the filter septum, comprising a shaft 8 with rotors 9. A shaft 8 is connected through an actuator 10 to an electric motor 11, which co-exists

to

This allows the shaft 8 with the rotor 9 to perform rotational and reciprocating movement. The clarified liquid is discharged through the pipe 12. The sludge is discharged through the pipe 13 with its further dewatering in the device 14, to dewater the sludge. ; The water separated from the sludge enters the cleared liquid nozzle 12 through the nozzle 15.

The self-cleaning filter operates as follows.

The initial contaminated fluid enters the housing 1 through the nozzle 2, passes through the filter septum 3 from the fine mesh into the chamber 7 of the clarified liquid and is discharged from the filter through the nozzle 12. the motor 11 and through the actuator 10 drives the shaft 8 into rotational and translational-reciprocating movement, the rotor 9 also begins to rotate, moving together with the shaft 8 along the filtering partition and 3. Vortex zones are formed around the rotor 9, which act on the screen of the filter septum and contribute to the separation of contaminants from it. Under the influence of inertial forces and due to the fact that the filter septum 3 is attached by flexible suspensions, it begins to vibrate, thereby contributing to a better separation of contaminants.

loosening and mixing the layer of suspended particles, not allowing the layer to condense and settle on the cells of the mesh of partition 3. Suspended particles that left the zone of action of the vortex flows under the force of gravity begin to settle on the membrane bottom 6, which oscillates due to the flexible suspensions 4, attached to it. Under the action of oscillations, the contaminants move along an inclined plane to the center of the bottom 6 and through the nozzle 13 enter the sludge dewatering device 14, where water and sludge is separated. Then, through the pipe 15, the separated water enters the pipe 2 for the clarified liquid.

The use of the present invention will improve the filter performance and environmental friendliness by improving the cleaning of the filter partition, returning the fluid after dewatering the sludge and disposing of the sludge.
