magnet 12. When the device is operating, a fibrous sediment accumulates in the gap between the cone and the output part of the supply nozzle as a filter element. As the pressure of the source fluid in the nozzle increases, the co-loop shifts downward with an increase in the gap, which accordingly reduces the filtration resistance, and lowering

the cone stops. With further accumulation of sediment in the gap, the cone is again lowered, etc. until the stop 13 comes into contact with the electromagnet 14 switch. The cone tail is drawn into the electromagnet and the sediment falls into the tank. The electromagnet is turned off from the time relay. 1 il.

The invention relates to the treatment of wastewater and other liquids from fibrous materials and can be used in the chemical, textile, processing and other industrial sectors.

The purpose of the invention is to increase the reliability of the device in operation.

The drawing shows a diagram of the device, a General view.

The device comprises a side 1 supplying patru, a cone 2 flow distributor and a tank 3 for collecting fibrous materials and filtrate.

The output part of the nozzle 1 is equipped with a conical socket 4, in which is placed a cone 2 with a gap of 5, the height of the variable with the smallest value in the lower part.

To the inside of the cone 2, a shank 6 is fixed, passed through the guide sleeve 7. The cone 2 is provided with a compression spring 8 placed between the stops 9 and 10.

Ferromagnetic shank 6 with its lower end enters the hole 11 of the electromagnet 12.

The lower part of the shank 6 is provided with a stop 13 in contact with the switch 14 of the electromagnet 12.

A filter element in the form of a perforated truncated cone 15 is installed in the tank 3, in a smaller base of which there is a reinforcing cylinder 16 dp of the shank 6 and an electromagnet 1 2.

The cone 2 is provided in the lower part with a cylindrical casing 17 and the spring 8 is attached to the cone 2 and the cylinder 16

The lower part of the container 3 is provided with a pipe 18 for draining the liquid.

The device works as follows.

In the absence of the initial fluid in the nozzle 1, the cone 2 is pressed by the spring 8 to the output part with the formation of a minimum gap.

The original fluid begins to filter through this gap, at which the fibers retain in the gap and quickly accumulate in it due to its small cross section. As the fibers accumulate in the gap, the pressure of the fluid increases and on the cone 2, which shifts downward and increases the gap 5 until an equilibrium is created between the flow of the source fluid into the nozzle 1 and the output of the filtered fluid. At the same time, the accumulated sediment in the form of - pressed fibers serves as a filtering element when liquid passes through this layer.

With a further increase in filtration resistance in the gap 5, the pressure in the nozzle 1 again increases, and the cone 2 shifts downward, increasing the gap 5.

After accumulating some limiting value of the sediment in the gap 5., the fibrous sediment is automatically discharged from the outlet part of the latrubka to the truncated cone 15.

In this case, the stop 13, when lowering the shank 6, presses the switch 14, which activates the electromagnet 12. When the lower part of the shank 6 enters the hole 11, the electromagnet further pulls the shank down, the cone 2 lowers, significantly increasing the gap 5, and the pressure of the column the original fluid and under the action of its own weight is dropped on the truncated cone 15, shifting radially to the wall of the container 3.

Under the action of a time relay (not shown), the electromagnet 12 is turned off and the cone 2 under the action of the spring 8 returns to its original position upwards and closes the output part of the nozzle 1 with the formation of a minimum gap. Next, the filtering cycle repeats. The casing 17 prevents the penetration of fluid into the slice pair: sleeve 7 - shank 6.
