(54) DEVICE FOR SMOOTING FIBER MATERIAL

(57) The invention relates to the pulp and paper industry,

in particular to devices for grinding a fibrous material, and allows

improve device reliability. Lubricating oil is forcibly supplied by the pump to the assembly of the spherical support 2, from where through the central hole 11 of the shaft 4 enters the bearing 5, then lubricates the sliding surfaces of the flange 8 and the spherical liners 9 and 10, then flows into the crankcase. The milled fibrous material is continuously fed through the feed hopper into the annular gap between the casing and the rotor, where it is subjected to multiple compression, as a result of which it is milled and discharged from the device. 1 il.

This invention relates to a paper industry, in particular to devices for grinding fiber matsfial.

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

The drawing shows the proposed device, a General view.

The device includes a housing 1, inside which, on a spherical support 2, a rotor 3 is suspended, equipped with a shaft 4, on which with a bearing 5 is mounted a sleeve 6 with unbalance 7, in the upper part the sleeve 6 has a flange 8 with which it rests on a spherical insert 9, being a self-aligning bogie. Similarly, the liner 10 is an abutment with the possible movement of the sleeve 6 upwards. Inside the shaft 4, an axial bore 11 is provided for supplying lubricant to the bearing 5 and to the thimbles 9 and 10. In the lower part, the sleeve 6 has a pinch seat for accommodating the upper head of the ball spindle 12, the lower head of which is installed inside the pulley 13 connected by a V-belt transmission 14 with electric motor (not shown).

The device works as follows.

The torque from the electric motor is transmitted through the V-belt transmission 14, the drive pulley 13 and the ball spivdel 12 to the unbalance sleeve 6, the rotation of which at the sliding bearing 5 around the shaft 4 creates a centro - force that causes the rotor to deviate from the axis of the device and complete run-in on the working surface of the housing 1.

The weight of the sleeve 6 and unbalance 7 is perceived through the flange 8 by a non-spherical liner 9. The upward movement of the sleeve 6 during operation of the device is limited by the spherical pin 10. The spherical shape of both inserted 9 and 10 allows the axis of the sleeve 6 to deflect the shaft 4 of the rotor 3 without damaging the sliding surface. Lubricating oil is forcibly supplied by the pump to the assembly of the spherical support 2, from where through the central hole 11 of the shaft 4 enters the bearing 5, then lubricates the sliding surfaces of the flange 8 and the spherical liners 9 and 10, then flows into the crankcase.

The milled fibrous material is continuously fed through the feed hopper into the annular gap between the casing and the rotor, where it is subjected to multiple compression, as a result of which it is milled and discharged from the device.
