BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention applies an impact between a rotating hammer and a crushing projection attached to the inner wall of a container to apply crushing impact to a crushed object such as garbage or metal cutting chips, and to apply a shearing force to the crushed material. The present invention relates to a horizontal pulverizer capable of directly discharging pulverized material from a high position to a transport bucket or the like.

[0002]

2. Description of the Related Art All types of pulverizers which have been used heretofore supply unpulverized material from the top or side of the pulverizer and discharge the pulverized material below the pulverizer. Therefore, in order to pulverize, using a conveyor or the like, the uncrushed material is put into the pulverizer from a high position, and another conveyor is often required to carry out the pulverized material discharged to a considerably low position, A large space was required for the equipment arrangement.

[0003]

The problem to be solved by the present invention is to supply unground material to a crusher at a low position,
An object of the present invention is to provide a pulverizer capable of discharging a pulverized material to a high position.

[0004]

According to the present invention, in order to solve the above-mentioned problems, pipe covers are provided on both end faces of a laid pipe 1 and a thread-shaped groove 2 is provided on the inner face over the entire length of the pipe. In a horizontal crusher equipped with a rotary drum 10 rotating at high speed around a pipe central axis and a hammer disk 18 mounted with a swinging hammer 16, a ring-shaped partition wall 61 is provided at the back of a crush projection mounting portion. A through hole 62 is formed in a portion of the crushing projection mounting portion immediately before in the direction of rotation of the hammer, and a space between the partition wall and the outlet-side pipe cover is defined as a crushed material discharge chamber 60. Equipped with a discharge arm 63 through which
A long hole is provided in the pipe between the partition wall and the outlet pipe lid in the circumferential direction, and the crushed material that has become smaller and passed through the hole opened in the partition wall and moved to the discharge chamber is rotated by the discharge arm. Then, the liquid is discharged from the discharge opening at a high speed in a rotational tangential direction.

[0005] A swingable supply arm 14 whose swing center is shifted outward from the center of the rotating disk is attached to a rotating disk 12 attached to the end face of the rotary drum 10 on the entrance side of the object to be ground, and the rotation of the supply arm. A disassembly protrusion is provided on the inner surface of the door as a door that opens a part of the pipe near the outer edge in the rotation direction, the supplied uncrushed material is disassembled by the supply arm and the disassembly protrusion, and the processing material mixed in the uncrushed material is disassembled. Detects uncrushable objects such as scraps and discharges them from the door.

[0006]

[Effect] A pipe lid is provided on both end faces of the laid pipe 1,
Equipped with a rotary drum 10 having an inlet opening 31 on one of the pipe lids, a threaded groove 2 provided on the inner surface over the entire length of the pipe, and blades rotating at high speed inside the pipe,
Supply arm 1 on a rotating disk attached to the supply end of the drum
4, a disintegration protrusion 54 is provided on the inner surface of the pipe near the outer periphery of the supply arm, and a pulverization protrusion 51 is provided near the outlet end of the inner surface of the pipe. If the uncrushed material is supplied from the entrance opening of the machine, the uncrushed material is rotated at a high speed by the rotating supply arm, and coarsely decomposed by the disassembly protrusions and the supply arm on the inner surface of the pipe, and between the rotating disk and the pipe. Move along the thread groove toward the outlet end of the pipe. The uncrushed material moved to near the outlet end of the pipe is then crushed by crushing projections and a hammer. A ring-shaped partition wall 61 is provided at the back of the crushing projection mounting portion, and a through hole 62 is formed in a portion of the partition wall immediately before the crushing projection in the rotation direction of the hammer, and the space between the partition wall and the outlet pipe lid is discharged. The discharge chamber is equipped with a discharge arm 63 whose rotating outer periphery passes near the inner surface of the pipe, and a long hole is formed in the pipe between the partition wall and the pipe lid in the circumferential direction to form a discharge opening 33, which is pulverized. Those that have become smaller and have passed through the hole formed in the ring-shaped partition and moved to the discharge chamber are rotated by the discharge arm and discharged at a high speed in the rotational tangential direction from the discharge opening.

[0007] A swingable supply arm 14 whose swing center is shifted outward from the center of the rotating disk is attached to a rotating disk 12 attached to the entrance end of the rotating drum 10.
A part of the pipe near the rotation outer edge of the supply arm is a door that opens in the rotation direction, and the disassembly protrusion 54 is provided on the inner surface of the door. In the case where is mixed, the uncrushable material hits the decomposition projection and generates a large impact vibration. This vibration is detected by an impact sensor, and the door is opened in the tangential direction of rotation to discharge non-crushable substances to the outside of the pipe. The gap between the supply arm rotating tip and the disassembly protrusion is made small, but if there is an uncrushable object, the supply arm will continue to rotate and retreat and rotate, and if a large uncrushable object is of course, even a small uncrushable object is larger than the gap. If a large shock vibration is generated, it is detected and the uncrushable matter is discharged from the door to the outside of the pipe.

FIG. 1 is a cross-sectional view of an embodiment of the present invention, in which a pulverized material discharge hole 62 is formed in the back of a hammer 16 and a pulverization projection 51 in front of a surface of the pulverization projection facing the rotation direction of the hammer. The partition wall 61 is provided, and the discharge arm 6
3. A pulverized material discharge unit including a discharge opening 33, a discharge guide 65, a pulverized material discharge chute, and the like is provided. In the pulverizer shown in this figure, only the material that has been ground to a certain degree or more moves through the holes to the pulverized material discharge section. Can be. If it is desired to further finely pulverize, the pulverized material discharge hole may be reduced.

FIG. 2 is a cross-sectional view of the pulverizer on the side of supplying the pulverized material.
The rotating disk 12, the air cylinder 57, and the uncrushable material discharged in the direction of the arrow are shown. Although the disintegrable projection is attached to the non-crushable material discharge door, when the door is opened, it is located outside the rotational tangential direction of the non-crushable material, so that this does not prevent the discharge of the non-crushable material.

FIG. 3 shows an example in which the crushed material is blown upward and discharged to a crushed material transporting cart 75 having a high input port. In the conventional pulverizer, the pulverized material is discharged to a position considerably lower than the input port of the pulverized material. Although a conveyor was required to raise the crushed material to the position, the crusher of the present invention can discharge the crushed material to a high position, and thus does not require such additional equipment.

[0011]

According to the horizontal pulverizer of the present invention, unlike the conventional pulverizer, a groove is cut in a horizontal pipe and the material to be pulverized supplied from one end of the pipe is forcibly moved in the advancing direction of the thread groove. The crushed object is moved to a crushing section at the back by rotating the crushed object at a high speed and crushed, and the crushed object is discharged in a rotational tangential direction from a discharge opening 33 opened in a pipe. Depending on the installation position, crushed material can be discharged to a high place or a distant place.Use a conventionally required input conveyor to lengthen the input position and use a problematic crushed material discharge conveyor It is economical and easy to operate and maintain.
There is also a great effect in that the required space is reduced.

Further, the swingable supply arm and the disassembly projection mounted on the rotating disk prevent the uncrushable material mixed in the supplied material from being caught without causing an excessive impact or stopping the grinder. When metal cutting chips are crushed for detection and discharge, large and small non-pulverizable materials such as large chips and small processed parts of the dropped processing material that could not be removed by the conventional crusher can be discharged. Not only is it easy to operate, but it can also be used for operation management and improvement of machine tools, and the effect is not limited to facilitating the processing of the crushed material, and is a great effect.
