The operation of the above “powder collecting cyclone apparatus” will be described. When the powder is introduced from the feed section through the feed conduit, the powder is spiraled along the inner wall of the cyclone main body along with the primary spiral rotating flow. It flows downward. And the powder which has a desired powder characteristic is collected by the collection canister. At the same time, a secondary spiral rotating flow is generated vertically upward in the spiral of the primary spiral rotating flow from the lower end of the cyclone main body, and a very light fine powder or dust is generated in the secondary spiral. Ascending with the rotating flow, the air is discharged from the exhaust pipe by the exhaust force of the blower (see paragraph 0053).

An embodiment of the present invention will be described with reference to the drawings.
1 to 3, the cyclone collecting device S includes a cyclone main body 1, first and second conical portions 2 and 3, a conveyance path 4 and an exhaust pipe 5.

The cyclone body 1 is formed in a cylindrical shape. The upper part of the cyclone body 1 is sealed by a top plate, and the first and second conical parts 2 and 3 are provided at the lower part. Each of the first and second conical portions 2 and 3 has a conical shape that is narrowed toward the lower openings 2a and 3a. The first conical portion 2 and the second conical portion 3 form a double conical structure in which the first conical portion is disposed on the upper side and the second conical portion is disposed on the lower side, and the openings are mutually open. It arrange | positions concentrically so that the center of the parts 2a and 3a may be located on the same straight line.
As shown in FIG. 3, the cyclone collecting device S is a non-sealed type because the second conical portion 3 located at the lower portion is opened by the opening 3 a.

As shown in FIG. 4, the conveyance path 4 is piped in a tangential direction with respect to the cylindrical cyclone main body 1, and one end of the conveyance path is connected to the upper part of the outer peripheral wall of the cyclone main body. The collected material is pumped through the transport path 4 and guided into the cyclone body 1.
As shown in FIGS. 2 and 3, the exhaust pipe 5 passes through the top plate of the cyclone main body 1, and the lower end portion of the exhaust pipe protrudes into the cyclone main body. Air containing dust and the like in the cyclone body 1 is exhausted to the outside of the cyclone body through the exhaust pipe 5.
In the exhaust pipe 5, an exhaust amount adjusting valve 6 for adjusting the exhaust amount of the exhausted air is provided.
In the cyclone main body 1, the collected matter separated from the air includes finely pulverized rubber, powder, and the like.

The operation of the illustrated cyclone collecting device S will be described with reference to FIG.
When the object to be collected is guided into the cyclone main body 1 together with the air through the conveying path 4, the object to be collected descends downward while swirling along the inner wall of the cyclone main body together with the primary spiral rotating flow F1. When the descending trapped material reaches the first conical portion 2, the turning motion is decelerated and is guided to the second conical portion 3 through the opening 2a while decelerating. In the same manner as in the operation in the first conical portion, while the turning force is weakened, it falls to the outside of the cyclone collecting device S through the opening 3a of the second conical portion, and processing such as recovery is performed.
At the same time, a secondary spiral rotating flow F2 is generated vertically upward from the first conical portion 2 at the lower part of the cyclone main body 1 through the spiral of the primary spiral rotating flow F1 by rotation opposite to the primary spiral rotating flow, Air containing fine dust rises with the secondary spiral rotating flow and is discharged from the exhaust pipe 5.
Since the lower cone portion of the cyclone body 1 has a double structure composed of the first and second cone portions 2 and 3, the first and second cone portions act to resist air inflow and the cyclone body. The inflow of air from the lower side is suppressed, and the trapped object is gradually lowered by the primary spiral rotating flow F1 and is discharged from the opening 3a of the second conical portion, while the air is the first conical portion. 2 reverses from the primary spiral rotating flow and rises to the upper part of the cyclone main body 1 as a secondary spiral rotating flow F2.
By these actions, the collected object and air are separated in the cyclone body 1.
In this way, the cyclone body 1 is a non-sealed type, but without having to perform operations such as stopping blowing air to the cyclone body, the collected collected matter can be continuously collected, In addition, when the cyclone collecting device S is connected to the processing device for the collected material, the collected material can be continuously supplied, so that continuous processing is possible in the processing device.
Further, by adjusting the amount of air exhausted by the exhaust amount adjusting valve 6, the inflow / outflow of air from the lower part of the cyclone main body 1 can be adjusted.

According to the roll crushing system R shown in FIG. 5, in the second roll crusher R2 and the third roll crusher R3 in which the cyclone collecting devices S2 and S3 are incorporated, the respective cyclone collecting devices capture the same. The collected object M, which is the collected object, is continuously collected in the supply chambers 22 and 32. Further, when the object to be crushed M in the supply chambers 22 and 32 reaches the level of the screw conveyor 71 of the overflow mechanism 7, the pulverized object to be overflowed is returned to the upstream side by this screw conveyor. 112, 211, 212 need not be controlled, the crushing efficiency is improved, and the storage parts 215, 315 below the screw conveyor 71 are always filled and stored with a certain amount of crushed objects. When the pulverized material is an elastic member such as rubber, high-efficiency pulverization is possible with its own weight.
Since the stirring paddles 121, 221 and 321 are used, if the object to be pulverized M is an elastic member such as finely pulverized rubber, the clogging and agglomeration are prevented by constantly stirring such a member to supply The accumulated state of the members in the chambers 12, 22, and 32 can be maintained, contributing to continuous and stable pulverization.

In FIG. 5, the upstream roll crusher is a single first roll crusher R1, and the downstream roll crushers are the second and third roll crushers R2 and R3. You may comprise with a single or 3 or more roll grinders.
The pulverizing rolls in the pulverizing units 11 and 21 are two sets of upper and lower pulverizing rolls, and the pulverizing roll in the pulverizing unit 31 is one set of pulverizing rolls, but the number of sets is not limited to the illustrated example, and the pulverizing units 11 and 21 include In this case, one set or three or more sets may be used, and two or more sets may be used in the pulverization unit 31.
It is not always necessary to install the stirring paddle depending on the type of the object to be crushed.
The object to be crushed as the object to be collected includes an elastic member such as rubber in addition to the tire piece of the waste tire.
