Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of crushing industrial waste (hereinafter referred to as "waste") generated after dismantling roads and buildings, and using the crushed waste as a recycled material such as basic grinders and compacted materials. Reproduction machine.

[0002]

2. Description of the Related Art After dismantling roads and buildings, a large amount of waste such as rubble is generated. Usually, these unprocessed wastes are called garbage, and are loaded on a vehicle, transported to a treatment plant, finely crushed, buried in the ground, or reused as aggregate.

[0003] As an apparatus for crushing the lashes, there is used a jaw crusher which presses and crushes the lashes between a plate-shaped fixed tooth and a rotating tooth, or an impact crusher which crushes by applying an impact with a striking projection. ing.
However, these apparatuses generate a large amount of noise and vibration during processing, and are difficult to transport. Therefore, these apparatuses are fixedly installed in a dedicated processing plant, which is inconvenient in use.

[0004] For this reason, the present applicant has developed and applied for a galley regenerator which operates with low noise and low vibration, can be transported, and can be worked at a dismantling site (Japanese Patent Laid-Open No. 7-472).
No. 94). This scraper recycling machine includes a primary roll crushing section having a pair of crushing cutters, and a secondary roll crushing section provided below the primary roll crushing section, and a crushing cutter of the primary roll crushing section in the secondary roll crushing section. It has a configuration in which a pair of crushing cutters that are straight and have a small gap are arranged.

[0005]

However, in the above-mentioned glass reclaimer disclosed in Japanese Patent Application Laid-Open No. 7-47294, the primary roll crushing section and the secondary roll crushing section are provided in two upper and lower stages. In addition to the necessity, the crushing cutters in the primary and secondary roll crushing sections are orthogonal to each other, so that the size in the height and width directions is large. For this reason, restrictions are imposed on miniaturization, and miniaturization beyond a certain level cannot be achieved. In addition, since the crushing cutter in each roll crushing section rotates individually, a large number of power sources such as motors for separately rotating are required, so that not only is the structure complicated and difficult to assemble, but also a large amount of power is consumed. In addition, the control is complicated.

[0006] The present invention has been made in view of such circumstances, and an object of the present invention is to provide a simple-structured galley regenerator that can be reduced in size and can be operated with a small number of power sources. I do.

[0007]

According to the present invention, there is provided a glass reproducing apparatus comprising:
A pair of rollers provided in the crushing chamber into which the glass is thrown and driven to rotate, and having a concave portion for biting the glass on the outer peripheral portion, arranged at a predetermined interval between the rollers, and an outer surface of the opposing roller. Multiple first crushing gala between
Crushing blade, and a plurality of crushing blades, each of which has a recess smaller than the recess of the first crushing blade on its outer peripheral portion and is provided on each roller in a state opposite to each other on both sides of the first crushing blade and crushes the rag. 2 and a drop prevention block protruding from the inner surface of the crushing chamber on both sides of the first crushing blade with a gap therebetween. In the above configuration, the fixed blade can be arranged below the first crushing blade so as to have a gap.

In the above configuration, since a plurality of first and second crushing blades are provided on a pair of rollers, the crushing blades rotate physically by rotation of the pair of rollers. The rotation of the first crushing blade causes the first crushing blade to bite a relatively large rattle and crush the roller with the roller. Due to this crushing, the glass, which has become somewhat smaller, is bitten by the second crushing blade adjacent to the first crushing blade, crushed, and falls downward. The fall prevention block is a garbage that is not crushed by the first crushing blade or the first crushing blade.
Even if the second crushing blade is crushed by the first crushing blade, the second crushing blade is prevented from falling downward. Thus, only the crushed pieces having a size equal to or less than a certain value fall downward from the crushing chamber, so that the pieces can be formed into pieces of a uniform size.

In this configuration, each of the first and second crushing blades has a one-stage structure in which a pair of rollers are disposed.
Moreover, it is not necessary to arrange them at right angles. For this reason, miniaturization and simplification become possible.

1 and 2 show a front view and a plan view of an example of an embodiment of the present invention. In this example, the scraper regenerator 1 includes a crushing chamber 3 and a shooter 4 provided in a frame 2 covering the entirety, and a pair of rollers 5 and 6 are disposed in the crushing chamber 3.

The crushing chamber 3 is open at the top and bottom, and a charging hopper 7 is attached to the upper opening so as to communicate therewith. The charging hopper 7 has a pyramid shape that diverges upward, and when the hopper is thrown into the hopper 7, the waste flows into the crushing chamber 3. As will be described later, the debris is crushed in the crushing chamber 3 and then drops on the shooter 4 which is connected to the opening below the crushing chamber 3. A conveyor 8 is provided at the lower end of the shooter 4, and the conveyor 8 receives the waste falling on the shooter 4. The conveyor 8 is inclined obliquely upward, and the tip end thereof is drawn out of the frame 2, whereby the crushed waste is discharged to the outside of the frame 2.

The pair of rollers 5 and 6 are arranged in parallel in the crushing chamber 3, and each is driven to rotate. Power sources 9 and 10 such as motors are mounted in the frame 2 to rotate the rollers 5 and 6. As shown in FIG. 2, the power sources 9 and 10 are
12 and the chains 13, 14 through the pulleys 15, 16
To rotate. The roller shafts 5a and 6a of the rollers 5 and 6 are connected to the pulleys 15 and 16 so that the rollers 5 and 6 rotate. This rotation is performed in the direction in which the looseness is wound between the rollers 5 and 6.

FIG. 3 is a plan view showing the inside of the crushing chamber 3. A plurality of first crushing blades 21 and a plurality of second crushing blades 22 are formed on a pair of parallel rollers 5 and 6 provided inside the crushing chamber 3.

The first crushing blade 21 has an outer diameter larger than the outer diameter of each of the rollers 5 and 6 and the outer diameter of the second crushing blade 22, and is welded to each of the rollers 5 and 6 or integrated therewith. Is formed. In this case, the arrangement of the first crushing blades 21 with respect to the rollers 5 and 6 is such that the crushing blades 21 are alternately positioned between the rollers 5 and 6. That is, the first crushing blades 21 of the roller 5 and the first crushing blades 21 of the roller 6 are arranged so as to be alternately shifted in the axial direction.
With such an arrangement, the first crushing blade 21 of the roller 5 faces the outer surface of the roller 6, and the first crushing blade 21 of the roller 6
The crushing blade 21 faces the outer surface of the roller 5. A gap of a certain size is formed between the first crushing blade 21 and the outer surfaces of the rollers 5 and 6 opposed to each other, and the gap is crushed when the gap bites into the gap. You.

FIG. 4 is a view taken in the direction of arrows AA in FIG. 3 and shows the outer shape of the first crushing blade 21. On the outer peripheral portion of the first crushing blade 21, “U” -shaped concave portions 23 are formed at predetermined intervals. The concave portion 23 is for winding the rag between the first crushing blade 21 and the opposing roller 5 or 6. That is, the rattle thrown into the crushing chamber 3 is engaged with the first crushing blade 21 by being hooked on the concave portion 23 formed in the first crushing blade 21 or being partially dropped into the concave portion 23. In this state, the first crushing blade 21 is engaged with the opposing roller 5 or 6 by the winding force caused by the rotation. Thereby, the looseness is crushed by the first crushing blade 21 and the roller 5 or 6.

In the illustrated example, the concave portion 23 has a shape in which two “U” -shaped grooves are provided in series, but the shape can be changed as appropriate as long as the shape engages with the rattle. Reference numeral 24 denotes a “V” -shaped groove formed between the recesses 23,
The width and the depth are smaller than the recess 23. The groove 23 acts to entangle small pieces of rag and crush it. As shown in FIGS. 3 and 4, protrusions 25 are formed at predetermined intervals on the outer surfaces of the rollers 5 and 6 facing the first crushing blade 21. The protrusions 25 are used to prevent the outer surfaces of the rollers 5 and 6 from being worn when the rollers 5 and 6 and the first crushing blade 21 crush the lashes. For a long time,
There are benefits that can be used. If the first crushing blade 21 is worn, the amount of wear is compensated for by adjusting the rollers 5 and 6 to approach each other.

The second crushing blade 22 is provided with the first crushing blade.
Are arranged on each of the rollers 5 and 6 so as to be located on both sides of the crushing blade 21. The second crushing blade 22 is the first crushing blade 22
Although the diameter is smaller than that of the rollers 5 and 6, they face each other. That is, the second crushing blade 22 on the roller 5 side
Is opposed to the second crushing blade 22 on the roller 6 side, and the opposing second crushing blade 22 bites the crush and crushes it.

FIG. 5 is a view taken along the line BB in FIG. 3 showing the structure of the second crushing blade 22, and the second crushing blade 22 on the roller 5 side and the second crushing blade 22 on the roller 6 side. The crushing blade 22 is facing. Second crushing blade 2 on each roller 5, 6
On the outer peripheral portion of the second 2, a U-shaped concave portion 26 similar to the first crushing blade 21 is formed at predetermined intervals. This second
The recess 26 of the crushing blade 22 of the
The width and depth of the first crushing blade 21 are smaller than that of the recess 23 of the first crushing blade 21. As a result, the second crushing blade 22 crushes small pieces that cannot be crushed even if the first crushing blade 21 is caught. Then, by being crushed by the second crushing blade 22, the waste becomes a reusable size and falls into the shooter 4 and is discharged. In order to surely crush the small rag, the second crushing blade 22 and the second crushing blade 22 are arranged so that the distance between the first crushing blade 21 and the rollers 5 and 6 is smaller than that between the first crushing blade 21 and the rollers 5 and 6.
Of the crushing blade 22 is selected. The second crushing blade 2
2 as well as the first crushing blade 21, “V”
A letter-shaped groove 27 is appropriately formed.

In addition to the above configuration, a fall prevention block 30 is provided in the crushing chamber 3. As shown in FIG. 3, the fall prevention block 30 is provided with rollers 5 of the crushing chamber 3.
6 protrudes into the crushing chamber 3 from the inner surface perpendicular to the axial direction. The fall prevention block 30 is arranged so as to be located on both sides of the first crushing blade 21 of each of the rollers 5 and 6, and has a predetermined gap with the first crushing blade 21. In the illustrated example, since the second crushing blades 22 are disposed on both sides of the first crushing blade 21, the fall prevention block 30 is provided on the inner surface of the crushing chamber 3 at the same position as the second crushing blade 22. ing.

As shown in FIG. 4, the fall prevention block 30 has a shape protruding from the inner surface of the crushing chamber 3 toward the first crushing blade 21. By providing such a fall prevention block 30 in such an arrangement, the first crushing blade 21
Prevents a glass of a size that cannot be bitten into the shooter 4 and prevents a glass that has been crushed by the first crushing blade 21 but has not been bitten by the second crushing blade 22. To do.

Thus, these wobbles are formed by the rollers 5, 6
It is in a rolling state above, is bitten by the crushing blades 21 and 22, and after being crushed by these, falls to the shooter 4 for the first time and is discharged. Therefore, it is possible to obtain a uniform size. Since the fall prevention block 30 has a gap with the first crushing blade 21, it is possible to drop the sand generated by the crushing of the glass. Thereby, since the sand does not become mixed with the rattle, the slip of the rattle on the rollers 5 and 6 can be prevented, and there is an advantage that the rattle can be smoothly bitten.

FIG. 6 shows a vertical section of the bottom of the crushing chamber 3. In the figure, reference numeral 31 denotes a fixed blade arranged at the bottom of the crushing chamber 3. The fixed blades 31 are provided with respective first crushing blades 21.
Is arranged below the crushing blade 21 at a predetermined interval. In this case, the fixed blade 31 has a predetermined gap with the corresponding first crushing blade 21 and has a shape that also extends in the direction of the roller 5 or 6 that crushes the rag together with the first crushing blade 21. Has become. That is, as shown in FIG. 4, the fixed blade 31 is curved along the outer peripheral shape of the fixed blade 31 below the first crushing blade 21 with a gap between the fixed blade 31 and the first crushing blade 21. The roller 5 facing the roller 21 has a curved shape along the outer peripheral shape thereof with a gap between the roller 5 and the roller 5. This structure is the same on the roller 6 side.

The fixed blade 31 is connected to the first crushing blade 21
And, in the configuration disposed below the rollers 5 and 6 opposed thereto, the mower sandwiched between the first crushing blade 21 and the roller 5 or 6 abuts on the fixed blade 31 as well,
This contact can further break the glass.
For this reason, in addition to being crushed by the first crushing blade 21 and the rollers 5 and 6 and the crushing by the fixed blade 31, the crushing of the rag can be reliably performed.

In the present embodiment having the above-described configuration, the power sources 9 and 10 are driven to rotate the pair of rollers 5 and 6 in the direction of winding. The rotation of the rollers 5 and 6 causes the first
And the second crushing blades 21 and 22 also rotate integrally. In this rotation state, by throwing in the waste from the introduction hopper 7, the breakage of the waste is started. The thrown-in glass flows into the crushing chamber 3, and the first crushing blade 2
It is caught and crushed by the first concave portion 23 or the concave portion 26 of the second crushing blade 22. At this time, the crushed pieces that have been crushed between the first crushing blade 21 and the rollers 5 and 6 and have a predetermined good size fall into the shooter 4 and are discharged by the conveyor 8. On the other hand, the mottle not having a predetermined size is pulled up on the rollers 5 and 6 and rolls on the rollers 5 and 6.

The second crushing blade 22 crushes the rag wound in the concave portion 26 to a predetermined size and drops the rag into the chute 4. The second crushing blade 22 also envelops the rolls on the rollers 5 and 6 without being crushed to a predetermined size between the first crushing blade 21 and the rollers 5 and 6, and also rolls up the predetermined size. Crushed and dropped. The fall prevention block 30 prevents the rolling that is rolling on the rollers 5, 6, that is, the rolling that does not have a predetermined size, from falling to the shooter 4 as it is. This makes it possible to reliably crush all the pieces to a predetermined size, and does not discharge the pieces that do not have the predetermined size. Therefore, it is possible to make the garbage of a regular size, and it is possible to reuse the garbage.

In this embodiment, both the first crushing blade 21 and the second crushing blade 22 are arranged on a pair of parallel rollers 5 and 6, and the crushing blades 21 and 22 are provided. 1
The crushing blades 21 and 22 do not intersect at right angles while being arranged in a step. Therefore, the size can be reduced. Also,
Since only the pair of rollers 5 and 6 are rotated, the number of power sources is reduced. Therefore, the structure is simple and the assembling is easy, and the power consumption is small and the control is easy.

The present invention is not limited to the above embodiment, but can be variously modified. For example, the fixed blade 31 may be omitted.

[0028]

As described above, according to the present invention, the first crushing blade and the second crushing blade are arranged on the pair of rollers to break the waste, so that the size and size can be reduced and the power source can be reduced. Can be reduced.
