The invention relates to devices for the liquid treatment of fibrous materials and can be used in the pulp and paper industry in pulping or thickening operations.

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

The drawing shows the proposed

device, longitudinal section. A device for treating a fibrous material consists of a drum 1 with a filter element 2, end walls 3 and 4, connected to the corresponding trunnions 5 and 6 mounted on supports for rotation, one of which (axle 5) is driven, and one with a transporting nozzle 7 fixed in the cavity of the drum 1 is fixed relative to the filter element 2, and the housing 8 with the nozzles of the supply 9 and the discharge 10 of the material being processed. The device has a receiving chamber 11 for the material being processed, fixedly attached on the input side of the material to the device and made with openings 12 in the end wall 4 of the drum 1, and a connecting end 13 to the input 6 of the processed material into the receiving chamber 11. The pipe 13 is connected with the fitting 9 of the material in the device, mounted on the housing 8.

An intermediate chamber 14 may be formed between the nozzle 13 for introducing the material to be processed into the receiving chamber 11 and the fitting 9. The receiving chamber 11 may have a fender visor 15 shaped as a truncated cone and connected centrally to the nozzle 13 to the wall of the receiving chamber 11 its smaller base.

The necessary rigidity and skeleton of the filtering element 2 of the drum 1 is provided by ribs 16. The holes 12 in the end wall 4 of the drum 1, which serve for the passage of material into the treatment area, can be formed by rado-knitting needles fixed in the hub 17 , or have another constructive implementation. Inside the housing 8, adjacent to the fitting 10 for the output of the processed product. ring partition mounted

18, and in the location area of the receiving chamber 11, the housing is provided with a fitting 19 for discharging liquid. On Paph 6 n area of the material from the receiving chamber 11 can be mounted disk 20 with a diameter greater than the diameter of the hub 17 of the end wall 4, but smaller than the inner diameter of the transporting nozzle 7.

The device works as follows.

From the electric drive through the trunnion 5, the drum 1 is rotated, and the trunks 5 and 6, the end walls 3 and 4, the filter element 2 with the ribs 16 and the conveying nozzle 7, as well as the receiving chamber 11 with the baffle shield 15 and the disk 20 rotate.

The material to be processed, for example cellulose pulp or other pulp, under pressure greater than the pressure inside the housing 8, is fed through the fitting 9, enters the intermediate chamber 14, and then through the annular channel formed by the trunnion 6 and the nozzle 13 enters the receiving chamber 11 and further through the holes 12 in the end wall 4 into the cavity of the filtering element 2 of the drum 1. The disk 20 together with the transporting nozzle 7 restricts the flow of material being processed along the filtering element 2. On the filtering element 2 there is a machining mat The rial is dehydrated, and the liquid passes through the filter surface of element 2 and collects in the lower part of the housing 8, from where it is removed through the fitting 19. The thickened material transporting the nozzle 7 moves along the axis of the drum 1 and, meeting the end wall 3 of the drum 1, extends from the inner cavity of the drum 1 into the lower part of the housing B and is withdrawn from the device through the nozzle 10. The ring partition 18 prevents agglomeral mixing. liquid material in the fender visor 15 - the output of the liquid processed material flowing from the walls of the chamber 11, into the housing 8, the annular gap between the wall of the chamber 11 and the outer surface of the nozzle 13.
