Description

Calcium chloride crusher {APPARATUS FOR CRUSHING CALCIUM-CHLORIDE}

The present invention relates to a calcium chloride crushing device capable of crushing solidified calcium chloride.

Salt and calcium chloride are produced in the form of powder, but during long-term storage, rainwater or moisture penetrates and melts them, and when the moisture evaporates again over time, the particles agglomerate and solidify into a large mass. .

In particular, the solidified calcium chloride becomes almost as hard as a stone and has a very large volume, so it cannot be used as it is for snow removal.

It is provided to pass through the vertices that become According to an embodiment, a guide hole 4103 through which the guide bar 5000 passes may be formed in the first pressing plate 4110 and the second pressing plate 4120 . A bearing configuration such as a bushing may be provided in the guide hole 4103 to prevent a play between the guide bar 5000 and the guide bar 5000, reduce friction, and prevent wear.

The roll mill 6000 crushes the crushed object first crushed by the pressing unit 4000 and/or the grinding unit 2000 into smaller particles. According to an embodiment, the roll mill 6000 is provided to rotate so that a pair of cylindrical rolls have one side facing each other and the abutted portion moves downward. Accordingly, the crushing object passes between the rolls and is crushed more finely by the roll mill 6000 . Concavities and convexities of various structures may be formed on the outer circumferential surface of the roll as needed. Alternatively, the outer peripheral surface of the roll may be provided with a smooth surface.

Since the mesh member 7000 is less crushed by the pressing unit 4000 and the grinding unit 2000 and flows into the roll mill 6000, an excessively large mass of crushing objects is prevented from flowing into the roll mill 6000. The mesh member 7000 may be provided between the pressing plate member 4100 and the opening 1100 . The lumps that do not pass through the mesh member 7000 may remain on the mesh member 7000 and may be crushed by being pressed again by the pressing unit 4000 .

The transfer unit 8000 moves the crushing object discharged under the roll mill 6000 after the crushing is completed to a set position.

In a state located adjacently, the control unit operates the saw blade driver 3200 to reciprocate the saw blade unit 3100 at high speed, and the bottom surface of the solidified crushing object packaged by the packaging material is crushed into the crushing container (1000). It is brought into contact on the saw blade part 3100 in the inner body. At this time, the packaging material of the crushing object is cut by the saw blade part 3100 so that the crushing object is discharged from the packaging material and accommodated in the crushing container 1000 . At this time, the crushed object in a state of being packed with the packaging material may be transferred onto the saw blade unit 3100 by a separate transfer device such as a crane. At this time, the crane grips the packaging material. Accordingly, after the packaging material is cut by the packaging material cutting unit 3000 and the crushing object is discharged from the packaging material, the packaging material may be discharged to the outside of the crushing container 1000 in a state held by the crane.

Thereafter, the control unit selectively operates the grinding unit 2000 and the pressing unit 4000 to crush the crushing object in the crushing container 1000 . At this time, when it is determined by the user's judgment that the degree of solidification of the crushing object is not severe enough to not use the grinding unit 2000, the control unit operates the grinding unit 2000 in a state in which the pressing driver 4200 is not operated. ) to move the first pressing plate 4110 and the second pressing plate 4120 toward each other to apply pressing to the crushing object to crush the crushing object. On the other hand, if it is determined by the user that the crushing object has been solid enough to be difficult to crush only with the pressing unit 4000 , the control unit operates the grinding unit 2000 and the pressing unit 4000 together to increase crushing performance. While the grinding unit 2000 and the pressing unit 4000 are operated, the packaging material cutting unit 3000 may not be operated.

For example, in this case, the control unit operates the linear driving unit 2200 so that the first grinding member 2101 and the second grinding member 2102 move toward each other, the first pressing plate 4110 and the second pressing The pressing actuator 4200 is actuated to move the plates 4120 towards each other. At this time, the control unit is a linear drive unit 2200 and pressing so that the first grinding member 2101 and the second grinding member 2102 first crush the crushing object than the first pressing plate 4110 and the second pressing plate 4120 . The driver 4200 may be controlled. For example, the control unit first moves the first grinding member 2101 and the second grinding member 2102 toward each other, or the first pressing plate 4110 and the second pressing plate 4120 and the first grinding member 2101 and the second grinding member 2102 are moved at the same time, the first grinding member 2101 and the second grinding member 2102 being advanced than the first pressing plate 4110 and the second pressing plate 4120 state can be moved.

The first pressing plate 4110, the second pressing plate 4120, the first grinding member 2101 and the second grinding member 2102 are provided to be movable only to a specific position that does not come into contact with the components located in opposite directions. can be The first pressing plate 4110, the second pressing plate 4120, the first grinding member 2101, and the second grinding member 2102 moved to a specific position are thereafter, the crushing vessel 1000. One inner surface of the inside and return to a position adjacent to the other inner surface. The reciprocating movement of the first pressing plate 4110, the second pressing plate 4120, the first grinding member 2101 and the second grinding member 2102 as described above may be performed singly or plural times, respectively, as needed. can

As described above, by selectively using the grinding unit 2000 according to the degree of solidification of the crushing object, it is possible to prevent unnecessary excessive use of energy.

The roll mill 6000 and the transfer unit 8000 may be operated simultaneously with the first packaging material cutting unit 3000 , and may be operated together while the grinding unit 2000 and the pressing unit 4000 are operated. The crushing object crushed by the grinding unit 2000 and the pressing unit 4000 is crushed once again by the roll mill 6000 and then transferred to a position set by the conveying unit 8000 .
