As shown in the figure, a grinding chamber 2 having a substantially quadrangular shape is provided on the upper portion of the support frame 1, and the grinding chamber 2 is rotatably driven by a driving motor 3, And a rotating roller 5 for pulverizing the waste product.

A plurality of grinding blades 6 are provided in the spiral direction on the outer circumference of the rotary roller 5 and a fixed blade 7 is provided on both sides of the inner wall surface of the grinding chamber 2, And when the rotary shaft 5 is rotated, it is crushed into small particles by the crushing blade 6 provided on the outer periphery thereof and the fixed blade 7 fixedly installed on the wall surface of the crushing chamber 2, The waste product to be crushed in this way is dropped downward through the clamping net 8 provided in a semi-spherical shape immediately below the crushing chamber 2 and discharged.

At this time, the droppings 8 are provided with a number of discharge holes having a predetermined size over the entire surface, so that only small particles to be pulverized are passed downward, and the relatively large pulp, which can not pass through the discharge holes, And then repeatedly crushed again.

However, even if the waste synthetic resin waste introduced through the inlet 4 is pulverized to some extent by the pulverizing blade 6 and the fixed blade 7 of the rotary roller 5, There have been caused various problems that the grinding efficiency is remarkably lowered due to the problem of the structure of the apparatus.

Hereinafter, an industrial waste grinder according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in the drawing, the industrial waste grinder according to the present invention is a grinder used in a conventional industrial waste disposal apparatus, which is primarily crushed by a crusher to transfer industrial waste moved by the conveyance conveyor 60 to a predetermined particle size or less It is a device for grinding again.

A second conveying conveyor 61 is provided below the crusher of the present invention. The crushed material conveyed by the second conveying conveyor 61 is dropped by the third conveying conveyor 62, and the third conveying conveyor 62) is subjected to a process such as removal of foreign matter through forced air blowing, and is then recycled according to the application.

Since the entire treatment system of industrial waste is already known, the detailed description of the present invention will be omitted, and a crusher for crushing the primary crushed crush again will be described in detail.

The crusher of the present invention comprises a casing 10 constituted by an upper casing 11 and a lower casing 12, a crushing roller 20 provided inside the casing 10 and a crushing blade 20 of the crushing roller 20 A stationary blade 30 which is spaced apart from the crushing roller 21 by a predetermined distance and which crushes the crushed material between the crushing blade and the screen 40 installed below the crushing roller 20.

The upper casing 11 is hinged to the lower casing 13 at one side thereof and hinged to the lower casing by a cylinder to open and close the upper portion of the lower casing.

An upper portion of one side of the upper casing 11 is provided with an inlet portion 12 for drawing industrial waste therein and a crushed industrial waste conveyed by the conveying conveyor 60 is introduced through the inlet portion 12 will be.

In the present invention, the lower casing 13 serves as a main body, and the crushing roller 20, the fixed blade 30, and the screen 40 are installed therein.

A lower portion of the lower casing 13 is opened and a second conveying conveyor 61 is provided in the opened portion to discharge the pulverized material discharged through the discharge hole 41 of the screen 40 to be dropped Is installed.

The crushing roller 20 is installed in a state of being rotatably supported by the lower casing 13. One end of the crushing roller 20 is connected to a drive motor 25 provided outside the casing by a power transmitting member such as a belt, And is rotated.

A plurality of crushing blades 21 are formed on the outer circumferential surface of the crushing roller 20 so as to crush industrial waste introduced into the casing.

The arrangement of the crushing blades 21 is such that the crushing roller 21 is disposed on the outer circumferential surface of the crushing roller 20,

'Shape. The reason for this is that the industrial wastes introduced through the inlet 12 are crushed by interaction with the fixed blade 30, and when they intersect with the fixed blade, they are crushed while sequentially intersecting the crushing blade at the center portion This is to increase the grinding efficiency.

In addition, the grinding blade 21 may be made of a material such as,

Of the crushing blade is arranged to be deflected toward the other side with respect to the center of the crushing roller (20). The reason for this is that the industrial waste introduced through the inlet 12 is guided to the other side of the crushing roller so as to be distant from the inlet 12. When the industrial waste is drawn into one side of the crushing roller, So that the draw-in of the industrial waste that is being drawn in can not be carried out smoothly.

For example, if nine grinding blades are '

', The fifth grinding blade is not positioned at the lowermost position but the sixth grinding blade is positioned at the lowermost position,

Quot; shape.

The crushing blade 21 includes a support block 21a welded to the outer circumferential surface of the crushing roller 20 and a crushing blade 21b integrally or detachably coupled to one side of the support block 21a. .

As shown in FIG. 6, the support block 21a is chamfered in the inward direction to form a welding surface 22 in order to widen the coupling area with the outer circumferential surface of the crushing roller.

7A and 7B, a welding surface 22 is formed by being chamfered inward at all sides in the lower portion of the support block 21a, and the welding area is increased by the welding surface 22, Can be increased.

This is because the grinding blade is subjected to a considerable load when pulverizing the waste, and it is possible to prevent the separation of the grinding blade even in the occurrence of such a load, thereby reducing the maintenance cost.

Since the crushing blade 21b is configured to crush the industrial waste while intersecting the fixed blade, the crushing blade 21b is formed of a metal material having high strength.

The crushing blade 21b may be welded to the support block or coupled with a coupling member such as a bolt. However, in the case of using a coupling member such as a bolt, it is preferable to integrally weld the coupling member rather than detachably coupling the coupling member due to difficulty in separation due to abrasion of the bolt during the pulverization process.

The fixed blade 30 is installed on the inner side of the lower casing 13 at a predetermined distance from the grinding blade 21 and can be installed only one. have.

In the case where two pieces are installed, the crushing operation is performed on both the left and right sides when viewed from the side, so that the crushing efficiency in the same time can be increased.

The fixed blade 30 may be coupled to the lower casing 13 with bolts or the like.

At this time, the fixed blade 30 is horizontally installed, and the crushing blade 21 is preferably inclined with respect to the fixed blade 30. (See Fig. 8)

The reason for this is that when the fixed blade 30 intersects with the fixed blade 30, they are intersected from either side so that the milling can be performed more easily, thereby improving the efficiency.

The installation angle of the crushing blade 21 is set to be inclined at an angle of 2 to 5 degrees with respect to the fixed blade 30. Beyond the angular range, there is no significant meaning.

The screen 40 is installed at a lower portion of the lower casing 13 and has an arc shape so as to have the same or similar curvature as that of the grinding blade 20 so as to form a retention space 45 between the grinding blade 20 and the grinding blade 20. [ And a plurality of discharge holes 41 are formed on the surface so as to discharge the pulverized industrial waste.

It is a matter of course that the diameter of the discharge hole 41 varies depending on the kind and use of the industrial waste to be crushed.

The crushing tip 42 is coupled to the inner surface of the screen 40 facing the crushing roller 20 so as to crush the crushed material staying in the holding space 45 by the interaction with the crushing blade 21. do.

Due to the engagement of the grinding tip 42, the pulverized material staying in the retention space 45 can be pulverized by the interaction by the grinding tip and the grinding blade.

That is, the pulverized material which has been crushed by the crushing blade and the fixed blade and then introduced into the holding space 45 is partially moved by the crushing blade during the rotation of the crushing roller and is crushed by interaction with the fixed blade again , The crushing effect was insufficient.

On the other hand, according to the present invention, the crushing blade intersects the crushing tip during crushing operation of the crushing roller to crush the crushed material existing in the crushing space, thereby remarkably increasing the crushing efficiency and reducing the amount of crushed material present in the crushing space There is an advantage in that the overall grinding time can be saved.

At this time, the grinding tips 42 may be horizontally arranged on the inner surface of the screen 40 at a predetermined interval in the width direction of the screen as shown in FIG. 9, or may be inclined as shown in FIG.

In the case where the grinding tips 42 are arranged horizontally, the grinding blade is inclined at an angle of 2 to 5 degrees, so that only a part of the grinding tip is deflected at the time of intersecting, so that grinding is easily performed.

In addition, when the grinding tip 42 is arranged in an oblique direction, it is easily grinded by being installed at different angles from the grinding blade.

The grinding tip 42 may be arranged on the inner surface of the screen 40 in a shape corresponding to the arrangement of the grinding blades 21 as shown in FIG.

In this case, instead of one of the crushing blade and the crushing tip being crossed, each of the crushing blades is crushed at the time of intersecting with the crushing tip, so that the crushed material present in the holding space can be more easily crushed . 9 and 10, when the grinding tip is horizontally or inclined in the width direction of the screen, as one of the grinding blades and the grinding tips intersect with each other, the intersecting portions of the grinding blades and the grinding tips intersect with each other, In the case of Fig. 11, this problem can be prevented and the crushing effect can be enhanced.

The guide block 50 may be formed on the inner circumferential surface of one side of the upper casing 11 so as to guide the crushed industrial waste introduced through the inlet 12 to the center of the crushing roller 20 have.

Therefore, the industrial waste introduced through the inlet 12 is moved along the inclined upper surface of the guide block 50 and is introduced into the center of the crushing roller 20, and the industrial waste introduced into the center of the crushing roller 20 The '

The crushing is performed while moving toward the other side of the crushing roller by the crushing blade arranged in the " shape ".

As a result, the amount of waste in the waiting time for grinding is relatively small compared to the other side of the pulverization roller, so that the waste is not interfered with the wastes waiting to be crushed when the waste is introduced through the inlet portion 12, .

In addition, the inner circumferential surface of the upper casing 11 of the present invention is formed with a scatter preventing protrusion 55 protruding at a predetermined interval. The reason why the scatter preventing protrusion 55 is formed is that the dust generated in the pulverization process of the industrial waste is scattered by the wind generated by the rotation of the pulverizing roller 20, 55) to reduce the amount of wind as well as the amount of wind.

According to the present invention configured as described above, when the industrial waste is introduced into the casing for crushing the primary crushed industrial waste to a predetermined particle size or less, the incoming industrial waste is moved to the other side of the crushing roller, It is possible to effectively prevent pulverization of the pulverized material existing in the retention space due to the formation of the pulverization tip, thereby improving the overall pulverization efficiency.

In addition, the dust scattered by the wind generated by the rotation of the crushing roller is prevented from scattering by colliding with the scattering protrusions 55, thereby reducing the amount of dust emitted to the outside through the inlet.
