SU469596A1 - The device for debarking of pulpwood - Google Patents

Description

The invention can be used in the timber and pulp and paper industry and is used for debarking pulpwood in the production of chemical chips.

BACKGROUND OF THE INVENTION There are known devices for debaring pulpwood, including a frame, a cylindrical body with cutting bodies on the inner surface and an actuator.

The disadvantage of such devices is work in the stationary or semi-stationary. M version, the duration of the wood debarking cycle in winter due to large heat losses.

The purpose of the invention is to provide a device mobility and increase the economy of the wood.

This is achieved by the fact that the cylindrical corus is mounted on oior rollers located around the circumference of its support surface and mounted inside the contours of the frame mounted on a movable platform; interacting with the annular support surface of the cylindrical body.

FIG. 1 schematically shows the proposed device, front view; in fig. 2 is a section along A-A in FIG. one.

ycTpoihCTBo for wood debarking consists of a movable platform 1 with a frame 2 fixed on it, inside the contours 3 of which the support rollers 4 are mounted, made with an annular groove 5 interacting with the annular support surface 6 of the cylindrical 7. Ooron rollers 4 are located around the circumference of the supporting surface 6 of they cylindrical housing 7 with cutting bodies 8 on the inner surface, driven by, for example, an electric motor 9.

To eliminate heat losses, a removable heat insulating jacket 10 is fixed around the perimeter of the frame 2 of the device.

The proposed device, which is included in the equipment set of the mobile plant for the production of process chips, works as follows. The mobile unit is brought to the place of storage of wood. Wood, for example, with a clamshell grab, is loaded into cylindrical corius 7. Timing occurs due to friction between the logs between themselves and cutting bodies 8, which, in contact with the wood, destroy the bark. To shorten the winter cycle, the heated air from the heat generator, which is included in the installation kit, is fed into the cylinder body 7. The removable heat insulating sheath 10 prevents the loss of heat supplied into the interior of the casing 7, and contributes to the shortening of the debarking cycle. The rooted wood is discharged to the conveyor through the unloading device, and the crushed bark separated from it is removed by transporter I.

After the wood has been processed, the plant is transported to another warehouse and the process is repeated. The mobility of the installation provides increased efficiency in wood debarking.
