Abstract

The invention relates to the pulp and paper industry, in particular to devices for treating fibrous material, and improves the processing quality of fibrous material by increasing the uniformity of its processing by controlling the feed rate of the material. The feed rate of the material being processed into the working chamber is adjusted automatically by varying the rotational speed of the rotor and the auger, depending on the degree of material loading by the working chamber. With a maximum load of the working chamber, the aperture of oscillations of the rotor, as well as the frequency of rotation of the rod with the screw and, consequently, the feed rate of the material is minimal. As the gap is unloaded and cleared from the material being processed, the frequency of rotation of the rotor and the screw increases and, accordingly, the material feed rate automatically increases. 1 il. with $ (L

The invention relates to the pulp and paper industry, in particular to devices for treating fibrous material.

C (according to the invention - improving the quality of processing of a fibrous material by increasing the uniformity of its processing by controlling the feed rate of the material.

The drawing shows the proposed device, General view.

The device includes a housing 1 with a loading 2 and a discharge 3 funnels, zgstanvenny on support 4 through elastic shock absorbers 5. with an unbalance of 11. The drive 10 is driven by a compensation clutch 12 and a timed transmission of 13 with an electric motor 14 (not shown). On the rod 7, in the area from the spherical platform 25 of weight 6 to the working surface of the rotor 8, the screw 15 is rigidly fixed. thirty

The device works as follows.

The torque from the electric motor 14 through the V-belt transmission 13 and the compensation clutch 12 is transmitted to the drive 10. The turning, unbalance 10 creates a centrifugal force that forces the rod 7 with the rotor 6 to deviate from the longitudinal axis and run 1. Due to the fact that the diameter of the inner cavity of the housing is greater than the outer diameter of the rotor, when the device is in operation, the rotor rotates around its own axis with a frequency depending on the ratio of the specified diameters and rotational speed of the balance .

For example, if the diameter of the cone is 300 mm, the diameter of the internal cavity of the body is 320 mm and the rotational frequency of the unbalance 1500, the rotor of the device will rotate around its own axis with a frequency of 100 rpm. Simultaneously with the rotor and with the same frequency, rotation will be performed and the rod 7 rigidly connected with it with the screw 15,

The processed fibrous material enters through the feed hopper inside the housing 1 and is then transported by turns of the rotating auger 15 into the gap between the rotor and the housing where it is subjected to multiple compression, resulting in grinding and unloading from the apparatus through the discharge funnel 3. The material in the working chamber is adjusted automatically by changing the frequency of rotation, depending on the degree of material loading by the working chamber. At the maximum load of the working chamber, the amplitude of oscillations of the rotor, as well as the frequency of rotation of the rod with the screw and, consequently, the feed rate of the material is minimal. As the gap is unloaded and cleared from the material being processed, the rotor speed will increase and, accordingly, the material feed rate will automatically increase.
