Description

[Detailed description of the invention] This is related to the rotary rotary machine.

Conventionally, in the paper and pulp industry, the disintegrating machine used for primary disintegration of raw materials is
A stone 2 is provided, and the rotor 4 is rotated by the shaft 3i, which is placed above the strainer 2, to generate a spiral circulation of the raw material in the tank 1, and the inner wall of the tank. The paper stock is disintegrated by the vertical stirring action of the material by installing the guiding blade 5 in the vertical direction, and by the stirring action of the double flow. Since the disaggregation ability cannot be improved by disaggregation, it has been attempted to improve the disintegration ability by attaching a disintegration blade 6 to the blade a of the rotor 4 and sloughing the raw material through the disintegration blade 6. However, as mentioned above, if the disintegrating blade 6 is simply attached to the blade a of the rotor 4, there is little opportunity for the raw material to be thrashed by the disintegrating blade 1, so that it is not possible to expect a sufficient improvement in the disintegrating ability.

The present invention was made in response to this current situation, and aims to increase as much as possible the chances of raw material being soaked.
Next 1. The purpose of the present invention is to provide a rotor for a disintegrating machine that has greatly improved disintegrating ability by providing a second disintegrating blade and a raw material guiding bar.

Next, an embodiment of a rotor for a disintegrating machine according to the present invention will be described with reference to the drawings.

In Fig. 2e of the drawing, 7 is a tub of the disintegrating machine, and the raw material causes a swirling flow and a vertical circulation due to the action of the rotor, which will be described later, to form a shape that is easy to move. A ring-shaped strainer 8 is attached to the diameter of the strainer 8. ! ; Drill a hole 9 of millimeters. JO is a processing material chamber provided at the bottom of the strainer 80, which collects the disintegrated material that has passed through the strainer 9 and sends it to the next process through a delivery pipe 11. With the shaft peeking out, connect the -L part to the knob means 13 from P 7
] (A passive wheel L7 is installed which is sealed, supported by bearings 14 in the middle, and driven by a belt chain from the lower end motor 15).

Several blades (g blades in the drawing) protruding from the front in the rotational direction (with a swept angle) around Ab, and one leading edge of this blade a with a swept angle The secondary St-blade 19 is attached, and the upper part of the blade a is the secondary defibration blade 19.

A raw material guide piece 2j is provided which is connected to the seventh order disintegrating blade 19 and is located above the blade a at a receding angle. , 2 (1 and the guide piece 21 have a slight elevation angle with respect to the 8 sides of the strainer described above, so that the raw material is pressed against the strainer 8 by this angle of elevation. 22 is the blade of the rotor 18 described above) Tip P of a Outer part of strainer 8 c t=
The cleaning blades are installed in correspondence with this, and the front edge has a slight elevation angle with respect to the 8 sides of the strainer, and the lower surface of the rear side is designed so that it gradually departs from the 8 sides of the strainer as it extends toward the rear. 23 are several raw material introducing vanes provided on the outside of the bottom of the tank 7, which are attached to the bottom of the tank 7 so as to give an elevation angle to the raw material flow, and their inner ends are connected to the rotor 1.
8 times closer. Reference numeral 24 designates several guide vanes extending along the inner wall of the tank 7, which are arranged vertically to suppress the swirling flow of the raw material and induce vertical circulation. Reference numeral 25 denotes a raw material introducing body installed vertically between the raw material introducing vanes 24, which has a triangular planar shape, and the raw material introduced between the guiding vanes 24, 24 from the slope F in front of the rotating direction. The flow is guided toward the introduction vane 23 and between the introduction vane 23 t and the vane a of the rotor 18. ') Yube, strainer outer diameter /3S
Assuming that the hole R is 0 mm, the hole R is 5 mm, and the outer diameter of the rotor is /; When the rotor 18 is rotated at a speed of 2'10 rpm, the blades of the rotor 18 and the 7th disintegrating blade near the center of rotation first cause horizontal and vertical recirculation stirring of the raw material to be processed. 20) This thrashes the processed raw material and guides the slashed raw material to the inside front of the primary disintegrating blade 19, and the connected guiding piece 21 moves out of the rotation range of the seventh disintegrating blade 20. In this position, in order to project the raw material 1 that is not to be thrashed outwardly and forwardly while adding some thrashing to the secondary disintegrating method 9, one secondary disintegrating blade is guided in front of it and projected as described above. In order to apply strong thrashing to the raw material again, the raw material is effectively decomposed into the next IF and projected outside the rotation range of the rotor 18, so that the raw material is transferred to the rotation of the rotor 18 by the inductor 25 and the introduction blade 23. By rubbing the material in such a way as to guide it back into the air and between the blades a, the chances of thrashing due to disintegration of the islands are maximized, which greatly accelerates the disintegration of the raw material and reduces the throughput per 7 days. /gO tons t reached, /day rate p/j□)n of the conventional disintegrator? Comparison O
ton increase, and a 3-0% improvement in capacity was observed. In addition, when a seventh-order defibration blade and a raw material guide piece are provided on the rotor blades and work together with the secondary defibration blade, the raw material is finely defibrated, so the wear of the defibration blade and strainer is large. Not only does it have a width (DI<41;), but it can also be removed upwards in the event of damage to the seventh disintegration blade or guide piece, so it can be easily removed with these supplements.

The rotor for a disintegrating machine according to the present invention has a leading edge 1 of each blade of the rope P, which is rotated from the shaft above the strainer at the bottom of the tank, with a backward angle of 1. The blade has a 6iJ inscription on the top surface, extending from the base of the secondary disintegration blade parallel to the 92nd disintegration blade toward the boss. The seventh disintegrating blade and the second disintegrating blade are connected to each other and the material guiding piece located on the blade is set at a larger receding angle than the second disintegrating blade, so the rotor When rotated, the 7th disintegration blade slashes the raw material and guides it to the secondary disintegration blade. From this, the thrashing material is slightly thrashed and projected onto the tertiary disintegrating blade, where it is then thrashed again. In order to increase the chances of thrashing the raw material through the rotor as much as possible, the throughput of the disintegrating machine is increased as described above. The JJ series 50-chi is also amplified, but the processed products are fine, so the quality of the product is good, there is less wear on the rotor and strainer, and the seventh disintegration blade and guide piece are on the blades. Since it is attached, it can be easily repaired, and even if the rotation speed is reduced, the processing time will be shortened by 1 cm, which will have a great effect on saving electricity, etc. be.
