Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a lint crusher, and more particularly to a lint crusher that improves the classification performance of finely pulverized particles and improves the quality of pulverized products.

The conventional own crusher has several crushing rollers 11 freely rotatable on a rotary table 9 that rotates while maintaining a horizontal state as shown at 1111wA, and the material to be crushed is placed on the rotary table 9. Then, the rotary table 9 and the crushing roller O11
The pulverized particles are introduced from the air supply port 12, and after a period of time 10, they are carried upward by the rising air #lK, and along the way, the particles in the moldy dish are Large grains of AT fall due to their own weight.

The coarse powder, which is further carried along by the air flow, is counter-transported by the reversing device 411 and is blown off from the air flow. The coarse powder thus fallen is pulverized again on the rotary table 9. On the other hand, large coarse powder is separated and nine mold powder is taken out as a crushed product from the fine powder outlet 13 along with the air flow.

By the way, in the layered III crusher shown in Fig. 1s1, the fineness of the pulverized product is determined by the performance of the rotary repellent blade 6'. The number of sheets is increased and the number of revolutions is increased. However, increasing the number of rotating repulsion blades 6' and increasing the number of rotations increases the pressure loss of the air flow required to transport the particles, increasing the power required for pulverization as a whole. There was a drawback. (9) In the l111 appetizer with such stratification, the flow of large particles in the particles that have been evacuated by the rotary reversing tool 6' is as shown by the dotted line in Fig. It rises again and is guided to the rotary reversing pot blade 6', resulting in a decrease in the classification effect of the i-converter conveyor 6' and a deterioration in the performance of the inspector crusher. Therefore, rotating repulsion blades 6
It became necessary to increase the number of ''s and increase the number of revolutions per rotation, making the above-mentioned drawbacks even more serious.

The present invention aims to eliminate the above-mentioned conventional drawbacks and provide a 9am appetizer crusher.

That is, in the present invention, a funnel-shaped chute is provided above the center of the rotary table, and this chute allows the pulverized particles to rise on the outer surface of the rotary table through an upward flow path (in this flow path, the pulverized particles A variable fixed vane is provided at the upper end of the chute in this channel to rectify the air flow, and this variable fixed vane A rotary repulsion blade is provided on the outflow side of the fine powder, so that the air flow uniformly flows out by the fixed blade and becomes a flow in the opposite direction to the rotational direction of the rotary anti-tight blade and is guided to the rotary repulsion blade. None, the particles crawled by air #lK are classified and classified by a variable fixture and a rotating repulsion blade along the inner surface of the chute.9l1fl11
% mold is formed by forming a channel into the crushing table.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the flea noodle crusher according to the present invention will be described below with reference to the drawings. In Fig. 2, reference numeral 9 denotes a rotary table, on which a plurality of crushing rollers 11 are rotatably arranged.At the upper center of the rotary table 9 is a funnel-shaped chute 8.
are generally connected to the upper end of the casing 14 via seven flange 16. The upper edge of the funnel of this chute 8 and the casing 1
A variable (6) fixed blade 1 is provided between the upper end of the casing 14 and the air introduced from the air inlet 12 into the casing 14 passes through the gap 1017 and flows into the crusher 1ii[16, where it is pulverized. Flowing upward along the outer surface of the chute 8 together with the particles,
The variable fixed blade 1 portion is generally configured to change the flow direction in the circumferential direction.

As shown in FIG. 3, a large number of variable fixing devices are fixed to a shaft 2, and the upper end of the shaft 2 is fixed to a ring member 3, and the ring member 3 is serially mounted on a drive device 5 via a connecting member 4. ing. Therefore, drive the drive device 5,
By rotating the ring member 3, the angle of the variable fixture 1 can be changed all at once.

6 in the figure is a rotary repulsion blade, and in this embodiment, a large number of round rods (square rods, strip plates, etc. are also missing) are arranged in a circular shape f1wL, and are located on the outflow side of the variable constant blade 1. It is fixed to the material to be crushed supply @ 7 and rotates together with the supply tube 7 . In addition, in the figure, reference numeral 15 denotes a cylindrical rectifying tube that is installed on the outer periphery of the rotary reversing blade 6 and can be moved up and down nine times. This is to control the inflow flow path. 13 is a fine powder outlet.

Next, the operation of the nine embodiments constructed as above will be explained. The material to be crushed is supplied from the material supply tube 7 to the chute 8.
It falls onto the rotary table 9 from the lower 5 WIA opening and is crushed by the rotation of the wrinkle rotary table 9 and the rotation of the crushing roller 11. It is pushed upward by the entrained air current. The particles carried in this manner are rectified by the variable fixture 1, become a flow in the y direction opposite to the rotating rotary repulsion blade 6, collide with the rotary repulsion blade 6, and flow through the gap therebetween. The inflow of particles into the rotary counter-conveying blade 6 is achieved by moving the rectifying tube 15 up and down and adjusting the angle of the variable fixture 10. Therefore, in addition to the classification effect of the variable fixture alone, the classification effect of the rotary counter-conveyor 6 is achieved. is adjusted to be optimal. Coarse powder in the particles thus crushed is efficiently brushed off and falls onto the rotary table 9 again along the inner side mK of the chute 8. On the other hand, the powder passing through the rotating repelling blade 6 along with the airflow flows out from the fine powder outlet 13 along with the air, and is taken out as a pulverized product.

As detailed above, according to the vertical crusher of the present invention, a funnel-shaped chute is disposed above the center of the rotary table to provide an upward flow path for crushed particles and a return flow path for coarse powder after classification. A variable fixed blade was provided at the inlet of the funnel-shaped chute of this upward flow channel, and a rotary repellent device was provided on the air outflow side of this variable fixed device. All of the nine particles rising will pass through the variable fixed blades and the rotating repulsion blades, and by adjusting the variable fixed blades, the inflow of particles into the rotating repulsion will be controlled at a relative speed to the rotational direction of the rotating repulsion. Since the particles are adjusted in the opposite direction of rising, the large coarse particles in the particles are classified by an efficiency storm. In addition, by classifying over 2fK with the variable fixed blade and the rotating repellent, the mixing ratio of relatively large coarse powder in the papermaking is greatly reduced, making it possible to obtain a pulverized product with uniform particles. This has the excellent effect of greatly improving the quality of the product.
