SU32913A1 - Continuous roll - Google Patents

Description

The proposed continuous roll has the aim, on the one hand, to use the valuable qualities of the roll as grinding tools, and on the other, to get rid of its undesirable properties, such as: low efficiency (from 1Q to 10%), periodicity of extreme bulkiness. A roll consists of a series of inclined canals with many knife drums consistently mounted in them and fixed planks. In order to establish the desired degree of additive of the slide bar to the drum, weights applied by crank mechanisms are applied.

In FIG. 1 shows a side view of a roll with a partial cut; FIG. 2 is a front view of a roll link with a knife drum and weights pressed against moving bars; FIG. 3 is a top view of a portion of the roll; FIG. 4, 5 and b - details of the design.

The proposed roll (Figs. 1-3) is, like a ladder or aspirator, several marches of narrow inclined cholob resting on iron kosoura 4; in the cholfer one after the other, knife drums 3 with ball bearings 5 and movable strips with hangers used crank (97)

The push mechanism, moving with B fixed boxes 8, the boxes themselves are attached to the same kosouram. The pressure on the slats is made by means of connecting rods, cranks 9, lever sectors Yu and cargoes //.

In order to avoid leakage of fluid through the joints of the strips with the boxes, a seal was applied using rubber diaphragms attached by means of frames 22 (Fig. 5) to the walls of the moving and fixed boxes with screws. The slats, in order to protect the diaphragms from damage, have a limited stroke. With the aid of fixing screws 20 (Fig. 4), the slats can be set at some distance from the drum blades. The number of reels is determined by. the required degree of grinding, the appointment of a roll for a certain type of paper and of certain materials. The slope of the tolobov is determined by a given speed of movement and thickness of the paper pulp, as well as by the degree of smoothness of the bottom and walls of the tolot. In order to reduce the friction coefficient of the mass on the bottom and walls of the wood chol, the latter can be upholstered with thin brass sheets J4; Reflectors / 5, also upholstered in brass, are made at the top of the chute to direct the mass cast away from the knives

The diameters of the drums, in view of the O1 presence of the roller coaster, can be three times smaller by DBA, as well as the width of the tols, due to the continuous feed and the high speed of the mass, due to their inclination. The knives of the 25 slats have a bend in the middle and alternately turn one mass of the drum towards the mass, and the next one against the turn, which, by directing the mass to the walls of the trough, then to the middle of it, promotes better mixing.

The top cover of the cholus is fastened to its part by means of bolts and gaskets. To eliminate the mass flow through the shaft, a copper ring is placed on it, casting the mass due to the centrifugal force into the cavity, from where it flows back into the trough through the hole 23 (Fig. B). Helical gears / 5 drums and bevel / 7 motors

f6 are encased and work in oil.

The mass, coming from the upper mixing vat into the feed hopper /, adjustable by a split valve 2, is subjected to the grinding effect of a certain number of drums depending on the degree of grinding and flows into the lower mixing roll for composition and sizing.

The subject matter of the invention.

Claims (2)
