[0013]

Embodiment 1 of the present invention is shown in FIG.
As shown in FIG. <A> Housing The housing 1 is an outer shell made of a steel plate that defines the crushing chamber 11, and has a cylindrical shape or the like. The capacity of the crushing chamber 11 is determined according to a desired crushing work amount.

<B> Rotating Crushing Blade The rotating crushing blade 2 is a rotating body in which a plurality of blades housed in a crushing chamber 11 are arranged in a radial pattern or the like. It rotates at high speed around the shaft 21.

The number and position of the rotary crushing blades 2 and the distance between the tip of the rotary crushing blade 2 and the inner surface of the housing 1 are appropriately determined in consideration of the crushing operation efficiency and the like. FIG. 1 shows a case where the housing 1 is of a vertical type so that the rotating shaft 21 is located horizontally, but the housing 1 may be of a horizontal type so that the rotating shaft 21 is located vertically.

<C> Ventilation path A ventilation path 3 communicates with a part of the side surface of the housing 1.
A blower, a compressor, and the like are connected to the other end of the air passage so that a desired wind force can be blown into the housing 1.

<D> Discharge path A discharge path 4 is provided so as to communicate with the side surface of the housing 1 so as to be located on a straight line with the blower path 3. The discharge path 4 is for discharging the crushed material after crushing to the outside of the housing 1. The other end of the discharge path 4 is communicated with a stocking location of the crushed material or a supply path 5 described later. And is circulated again in the housing 1. Note that the air blowing path 3 and the discharging path 4 may not be straight.

<E> Supply Path The supply path 5 is arranged closer to the discharge path 4 side than the blow path 3 and communicates with the side surface of the housing 1. For example, FIG.
, The housing 1 is obliquely communicated with the peripheral surface on the left half side of the housing 1. The supply path 5 and the discharge path 4 may be parallel. Thus, along the rotation direction of the rotary crushing blade 2,
A supply path 5, a blowing path 3, and a discharge path 4 are provided in this order. And a wide crushing zone 6 from the supply path 5 to the discharge path 4 can be secured.

The supply path 5 is configured to be capable of supplying crushed raw materials, and to branch and connect blowers to supply crushed raw materials without being clogged in the housing 1 by wind power. In addition, the supply path 5 may be connected from the upper side so that the crushed raw material can be naturally dropped. In addition, a plurality of supply paths 5, air supply paths 3, and discharge paths 4 may be provided in some or all of them.

[0020]

The rotating crushing blade is rotated to supply crushed raw materials such as ice blocks into the crushing chamber through the supply path. At this time, the blower is operated, and the crushed material is crushed by the wind power in the crushing chamber 1
1 into the housing 1
To prevent clogging at the entrance.

The wind power for sending the crushed material is
Since it is much smaller than the wind power required to discharge the crushed material after crushing, the collision force with the rotary crushing blade 2 is attenuated and the crushing efficiency is not reduced as in the related art. At this time, if the natural fall of the crushed raw material can be used, the wind force sent from the supply path 5 can be reduced accordingly.

Furthermore, the crushable crushing zone 6 in the crushing chamber 11 of the present apparatus is located between the supply path 5 and the discharge path 4 in the direction of rotation of the rotary crushing blade 2, so that The crushing zone is greatly expanded, and the crushing efficiency can be improved.

At the same time as the supply of the crushing raw material, the blower on the side of the blowing path 3 is operated to send a predetermined wind force into the crushing chamber 11. The wind force required at this time is a wind force capable of discharging the crushed material such as fine ice particles after crushing to the outside of the crushing chamber 11 via the discharge path 4.

[0024] Thereby, the water is supplied into the crushing chamber 11,
The crushed material crushed by colliding with the rotary crushing blade 2 can be discharged to the outside of the crushing chamber 11 through the discharge path 4.

[0025]

[Embodiment 2] FIG. 2 shows a case where the supply and blowing of the crushed raw material are performed in a supply path 51, and a wide crushing zone from the supply path 51 to the discharge path 41 is secured. In this case, it is preferable that the opening area of the supply path 51 is formed to be larger than the opening area of the discharge path 41 so that the wind force sent from the supply path 51 is accelerated in the discharge path 41.

As a result, the wind power in the supply path 51 can be reduced, so that the collision force with the rotary crushing blade 2 is attenuated and the crushing efficiency does not decrease as in the related art. At this time, if the supply path 51 is communicated from the upper side of the housing 1 and the natural fall of the crushed material can be used, the supply path 5
The wind force sent from 1 can be small.

[0027]

Since the present invention has been described above,
The following effects can be obtained. <B> Since the supply path of the crushed raw material and the blow path are separated, the crushed material can be effectively discharged, and the crushing efficiency can be improved.

<B> Since the opening area of the supply path for supplying and blowing the crushed raw material is formed to be larger than the opening area of the discharge path, the wind force sent from the supply path is accelerated in the discharge path. The material can be effectively discharged, and the crushing efficiency can be improved.

<C> Since the supply path of the crushed raw material is provided near the discharge path, the crushing zone can be secured considerably wide, and the crushing efficiency can be improved.
