Description

one

The invention is intended for the production of wood pulp in the pulp and paper industry.

A continuous weight finisher is known, including a B1) solid stone, a hyacinth and a) balance feeding and clamping mechanisms fitted from two sides of the shaft, equipped with slewing pads.

However, in the well-known grinding wheel, the design of the mechanism for supplying and clamping the balance is unreliable and essential in operation.

The purpose of the invention is to increase the reliability of the operation of the (d) end-to-end operation.

This is achieved by the fact that each feeder and the balance of the balance are made in the form of moving sectors mounted on a common axis, and its rotational marshalls are mounted along the curvilinear forming surface sector.

FIG. 1 shows the proposed grinder, a vertical section; in fig. 2 - the same, side view.

The grinder contains a stone / stone grin mounted on the bearings in frame 2. The bed 2 is located a shaft 3 with guide rails 4. In shaft 3, grooves are inserted into which

working pressure shoes 5, located on sectors 6 and 7.

The bashmaks 5 are connected to the axle sectors 5 and are set in the working position on the unors 9, forming together with sectors 6 or 7 one rigid lever set in motion by the hydraulic cylinders 10 and 11 for the average 6 and extreme 7 sectors.

Sectors 6 and 7 are located on the same level on both sides of tongue 3 and rotate on two axes 12 fixed in it.

Clamping shoes 5 are freely rotated on the axis x 8 at a certain angle, limited by the stops 9.

The guiding beams 4 of the saddle 3 defibers are located in such a way that the generators of sectors b and 7 do not protrude into the shaft behind the guide beams 4.

Gpdrotsiliiry 10 and 11 in the upper part of Schachta 3 are fixed pivotally and have a small swing angle.

The proposed continuous weight is as follows.

The balance in the drill 3 of the grinder with a certain force is pressed against the stone by the bashmak 5, which in the working position rests on the stops 9. As the abrasion progresses, the balance of the constant goes down along the widened bottom of the schacht 5 and is a movable system that is under a constant pressure of the pressure pads 5 , seized on sectors 6 and 7.

Sönppe sectors 6 operate simultaneously, turning around a certain angle about axes 12, under the action of forces from JO hydraulic chains. The lateral sectors 7 from the hydraulic cylinders // work with NNMN.

The work cycle of sectors 6 and 7 is made up of the working stroke of the balapse field by means of sectors 6, at the same time idling the lifting of the side sectors 7, the working stroke of the balance sheets with its lateral 7 and simultaneous idling of the middle sectors 6.

The turn of the sectors of 6) 7 from the upper working side down down of the bay 5, 11111ED1I1e from the zone N1ahty, him, is biased on the axes 8 to the working direction due to non-uniform moment. The baikmaks 5, which are not completely out of the way, are introduced into the balance of the working hours of sectors 6 n / a, infuse the balance and increase the balance between them and the balance.

and equal to the transmission of the Eogo pressure on the surface of the stone, the beginning of the working stroke of its actuators, which is in the upper position, is temporarily ahead of the end of the working stroke of the sectors, which is in the lower position.

Thus, sectors 6 and 7 work with ncKOTOpBiM non-opening.m and about time. At the same time () 6niee the pressure of the balances on the chamber W remains unchanged.
