According to the present invention, the reproduction of the glass is performed as follows. First, the waste is put into the primary roll crushing section, and crushed to a predetermined size in the process of passing through the gap of the crushing cutter. Subsequently, in the process of passing through the gap between the crushing cutters in the secondary roll crushing section, the crushing is further reduced, and those that cannot be crushed are taken out of the machine by stopping the primary and secondary roll crushing sections. At that time, the secondary roll is prevented automatically generating a quenched by noise and vibration the drive signals the load detector is a primary roll crushing part and the load is applied to the driving unit of the secondary roll crushing unit relatively while preventing excessive load from being applied to the secondary roll crushing part by reversing driving the crushing part
Drop a small object from the gap in the crushing section .

[0006]

Next, the present invention will be described in more detail with reference to FIGS. FIG. 1 is a longitudinal sectional front view of a galley reproducing machine according to an embodiment of the present invention, FIG. 2 is a transverse sectional view taken along line XX of FIG. 1, and FIG. 3 is a longitudinal sectional side view of the same. The scraper recycling machine 1 is provided with a primary roll crushing unit 4 at a lower portion of an inverted quadrangular pyramid-shaped charging hopper 3 provided at an upper portion of a frame 2. A secondary roll crushing unit 12 is disposed below the primary roll crushing unit 4 via an intermediate hopper 10 so as to be perpendicular to the primary roll crushing unit 4.
8 are connected to form the whole.

The primary roll crushing section 4 is composed of two crushing cutters 5 and 5 made of high manganese cast iron with a predetermined gap therebetween. Spiral teeth 6 are formed on the outer peripheral surfaces of the crushing cutters 5, 5. Each crushing cutter 5 is connected to a drive unit 9 such as an AC motor via a sprocket 7 and a chain 8. The crushing cutters 5, 5 can be easily replaced by inserting and removing a bottle (not shown).

The lower portion of the intermediate hopper 10, like the input hopper 3, is converged in an inverted quadrangular pyramid shape, an outlet window 11 is provided on the side surface, and the lower end is connected to the secondary roll crushing section 12. Similar to the primary roll crushing unit 4, the secondary roll crushing unit 12 is configured by mounting two crushing cutters 13 made of high manganese cast iron having spiral teeth 6 on the outer peripheral surface in parallel. Like the primary roll crushing unit 4, the crushing cutter 13 is connected to driving units 16, 16 via a sprocket 14 and a chain 15, respectively.

However, in order to crush the lump B more finely than the primary roll crushing section 4, the crushing cutters 13, 13 of the secondary roll crushing section 12 are compared with the crushing cutters 5, 5 of the primary roll crushing section 4. The gap is set narrow. By adjusting the gap between the crushing cutters 13, 13, the recycled material C can be changed to an arbitrary particle size (40 mm to 0 mm at maximum). The crushing cutters 13 and 13 can be easily replaced by pins. In the secondary roll crushing unit 12,
Load detection unit 1 for detecting a load applied to drive units 16
7 and 17 are provided side by side, and a calculation unit (not shown) for stopping the primary roll crushing unit 4 when the load exceeds a predetermined value is provided. As described above, in the present embodiment, the primary roll crushing unit 4 and the secondary roll crushing unit 12 have the upper and lower two-story structure. However, as described above, the crushing of the secondary roll crushing unit 12 is orthogonal when viewed from above. The central axes of the cutters 13, 13 are aligned with the central axes of the crushing cutters 5, 5 of the primary roll crushing section 4.
The feature is that it is orthogonal .

The take-out hopper 18 is attached below the secondary roll crushing section 12 and comprises side plates 19, 19 and a bottom plate 20, as shown in FIGS. Bottom plate 2
The lower edge of 0 is disposed close to the upper surface of the conveyor 21. At this time, the inclination of the bottom plate 20 is increased, and the tip is arranged near the lower part of the front end of the tooth 6 so that all the regenerated material C falling on the conveyor 21 is once received by the bottom plate 20. . Accordingly, there is no possibility that the rubber belt of the conveyor 21 is cut or damaged when the recycled material C falls.

The conveyor 21 is of a divergent type, and a guard 22 for preventing scattering is provided below the take-out hopper 18. As shown in FIG. 1, the conveyor 21 is installed obliquely upward from the lower side of the take-out hopper 18, and its height can be adjusted by an adjusting mechanism 23, and the frame 24 is mounted by wheels 24 attached to the lower end. 2 can be stored. Although only one conveyor 21 is shown, the connection can be controlled up to a total of three according to the situation at the site.
1 and 2 is the conveyor 2 described above.
1 is an operation switching device that switches the secondary roll crushing unit 12 to an independent operation in addition to the control of the crushing cutter 1 and the automatic control of the crushing cutters 5 and 13.

A description will be given of a waste recycling process using the present embodiment. Input hopper 3 using backhoe etc.
And the crushing cutters 5 and 5 of the primary roll crushing unit 4 are operated to rotate so as to feed the gap A to each other as shown in the direction of arrow R in FIG. ). Gala A having a diameter of about 800 mm is passed through the gaps between
It is crushed into a lump B having a diameter of about 00 mm.

200 m crushed by the primary roll crushing unit 4
The lumps B having a diameter of about m fall into the intermediate hopper 10 and are sequentially sent to the secondary roll crushing unit 12, and similarly to the crushing cutters 5, 5 of the primary roll crushing unit 4, the secondary roll crushing unit 12 that rotates forward. Is finely crushed by the teeth 6 of the crushing cutters 13, 13 to obtain a recycled material C having a diameter of about 40 mm.

However, when the intermediate hopper 10 becomes full during the process from the primary roll crushing to the secondary roll crushing, the crushing cutters 13 and 13 of the secondary roll crushing unit 12 are used.
, And the amperage of the driving units 16 and 16 (motor) increases to a predetermined value or more. Therefore, in the present embodiment, this change is detected by the load detection unit 17 and a signal is sent from the calculation unit to stop the driving units 9 of the primary roll crushing unit 4. Then, only the secondary roll crushing unit 12 operates to process the lump B in the intermediate hopper 10, and when the load of the driving units 16, 16 of the crushing cutters 13, 13 returns to a normal value, the primary roll crushing unit 4 is again activated. Drive units 9, 9 operate.

Further, if foreign matter such as a lump of iron or a broken motor enters the intermediate hopper 10, crushing by the crushing cutters 13 of the secondary roll crushing section 12 becomes impossible. Therefore,
In such a case, a relatively small object such as sand is dropped from a gap between the crushing cutters 13 and 13 by automatically reversing the crushing cutters 13 and 13. As a result, only the foreign matter D of the fist size remains in the intermediate hopper 10. The foreign matter D is taken out by stopping the primary roll crushing unit 4 and the secondary roll crushing unit 12 and opening the take-out window 11.

In this embodiment, a series of these controls is performed by sequence control, and according to the crushing situation,
The crushing cutters 13 and 13 are automatically rotated in the forward and reverse directions. However, if the diameter of the galley A is small, the operation switching device can be switched to manual and only the secondary roll crushing unit 12 can be operated independently to perform processing. It is.

As described above, according to this embodiment,
With a gala A having a diameter of about 800 mm, it can be immediately crushed on site without being transported, so that transportation costs, time and labor can be greatly reduced.

Although the rotation speed of the crushing cutters 5 and 13 is set relatively slow, the crushing cutters 5 and 13 having excellent wear resistance gradually crush the primary crushing to the secondary crushing. Therefore, the total crushing rate can be enhanced, and scattering of dust during processing can be suppressed. Especially the teeth 6 of the crushing cutters 5 and 13
Since the mounting shape of is spiral, the efficiency of biting into the pieces A and B is also improved. In addition, the crushing cutter 13, 1
By adjusting the gap of No. 3, the diameter of the recycled material can be reduced to 40 mm to 0 m.
can be adjusted to m.

Further, when a load exceeding a certain level is applied, the crushing cutters 13 and 13 are stopped, and a series of operations are automatically controlled, so that the operation can be performed safely. Therefore, maintenance and inspection are easy. In addition, as described above, the rebar or the like that has passed through the secondary roll crushing section 12 once hits the bottom plate 20 of the take-out hopper, is buffered, and then falls onto the conveyor 21, so that the rubber belt of the conveyor 21 is cut as in the conventional case. There is also an effect that the fear has been reduced.

In this embodiment, the primary roll crushing unit 4 and the secondary roll crushing unit 12 have a two-story structure to reduce the size and save the space. The secondary roll crushing unit 12 is connected to the secondary roll crushing unit 12 by a mechanism that can be easily separated. In a processing site where the height is limited, the primary roll crushing unit 4 and the secondary roll crushing unit 12 are installed in parallel. Is also good. Further, when the lash is small, the purpose is achieved by using only the secondary roll crushing unit 12.

[0021]

According to the present invention, since the waste recycling machine of the present invention has a two-story structure and is made compact as a whole, the space required for installation can be made as small as possible, and dismantling and construction work are not hindered. In addition, the crushing power is strong because the noise and vibration are kept low because the crushing of the waste is performed step by step. Therefore, while being able to respond flexibly to some foreign matter such as reinforcing bars,
Dust is not scattered during processing, and it is also excellent in terms of environmental protection. Furthermore, since the processed recycled material can be used immediately as a basic grind and a compaction material on site, there is an effect that the trouble and cost for carrying in and carrying out the waste can be minimized.
