(54) FIBER MATERIAL DISCOVER

one

The invention relates to the pulp and paper industry and the use of devices for the grinding of fibrous materials.

According to the main author. St. No. 602640 allsane fiber breaker, which is a parallel to each other parallel gear racks divided into several groups, with the rails of one group alternating with the rails of the other ippy. At opposite ends of the rails, there are shafts made in the form of end-to-end eccentric barrels: barrel-necks 1.

The described breaker crushes the material under the action of a feeding agent, for example a puaison, and requires a charging agent, for example, a bukker. This limits the convenience of his work.

The aim of the invention is to improve the convenience of work while maintaining the quality of grinding.

This is achieved by the fact that the fiber material breaker has additional groups of gear racks, which are fitted along the redline on one of the shafts at an angle to the groups of main gear racks.

The drawing shows the proposed breaker.

The breaker is parallel to each other at a small distance from each other, toothed reimi, divided into groups 1 and 2, and the rails 5 of one group alternate with the rails and the other group. At opposite ends of the reyas there are shafts 3 and 4 and are connected to the knife racks through bearings 5. Each (the shaft along its entire length is made in

10 as a side-by-side set of eccentric working journals 6, which are displaced relative to each other and the central axis of the shaft in cross section for some distance / and are located at a certain angle a,

15 which determines the number of lath groups. These values are selected constructively and determine the number of groups of strips.

The design of the shafts can be changed to give the knife rails a combined movement, as is the design of the hem. Eccentric working journals in shafts 3 and 4 can be displaced from one another along the length of the shaft, as are the rack bearings.

The knife blades are placed at a certain angle p, which can vary from several degrees to 180 ° and more. The design of the rails, as well as their number on one bearing, may vary and may also have one- or two-sided

The teeth are located, with the stroke, amplitude, frequency, pitch, shape, divorce, slope, and their direction also vary.

The shafts on their ends are interconnected by chain leredaches (: not shown in the drawing) for their synchronous rotation. The design, as well as the arrangement of “predaccats,” may vary.

Group shafts 4 have I1ndi, 1 nd dual (non-rotary drives to give them rotational motion. Individual drives can Eat and auxiliary shafts 3. Shafts 4 can be made stationary: either mounted or suspended). In the latter case they are supplied with drives 7 in the form pneumatic or hydraulic actuators and connected to the shafts 3 pivotally through the STOK1I 8.

The breaker operates as follows.

The fibrous material to be dug enters the wedge cavity of the diffuser, for which one of the rods 8 puts the left or right group of rails into a horizontal position, and the reel rolls onto the slats. The shafts 3 and 4 rotate from the drives (not shown) synchronously around the central axes, the rotation control of which is chosen clockwise against. The eccentric offset p axes of the working necks of the shafts at this time make a rotational synchronous movement around the central axis (arrows B B). At the same time, the Grulls of the knife rails make a combined movement with respect to each other. This movement is decomposed into radial and tangential, while one group moves to the material being crushed, bursts into it and leaves it, pulling out 1 (I am from it pieces of material of an indefinite shape. The second group of knife slats located in the interval of knife slats of the first group takes its place, and the first takes the place of the second. The cycle repeats and causes the material to be torn.

For the efficiency of the grinding process, at the same time as the rails move relative to each other, the rails converge to each other using the rods 8 of the drives 7, changing the angle p of the wedge strip. If necessary, equilateral grinding of the defective layer of the b-bnna, the angle p may be constant or change in the direction of

thus increasing the rotational movement of the reel around its own axis (arrow G). Unloading of the nod | milled; bobbin or its core is performed by lowering the rods from groups of knife rails or by raising to the upper extreme position of the pile 4 with the stem 8.

Thus, the breaker performs

in addition functions of the giving and river unloading device, and also the bunker. It is possible to unload materials that are not to be crushed into the breaker for springing reels of variable and unlimited diameter w. Changing the angle p during the operation of the shredder, as well as the design of the shredder, make it easier to shred materials in appearance (keel, bobkn, etc.), and also increase the efficiency of the shredding process, as the grinding area increases and the load can be changed. Such a design allows us to make it more convenient in operation, so that you can use the reverse

the side of the knife rails with the teeth of another pitch or shape and change the degree of grinding, 1not replacing the RJ knife blade, turning the grinder in the opposite position. It can be used with a new suspension and a trailer over a hydraulic pulper, a defibrator, a dust collector, or a conveyor for bale unloading or mobile shifting.

Everything together makes a chopper

convenient in operation when grinding materials on various technological lines, without requiring its modernization or reorganization.
