Description

[Detailed Description of the Invention] The present invention relates to a crushing equipment for efficiently sorting out items within specified dimensions from items crushed by a crusher.

When dumping or landfilling industrial waste, it is required that the size of the dumping or landfilling be smaller than a cube with a side of 15 Qmm, and conventionally, this type of sorting involves creating a large number of drop holes in a crusher with a size that allows for dumping or landfilling. It had a built-in screen to control particle size.

However, some of the shredded items that are large enough to be dumped or landfilled do not fall through the drop hole and are crushed again, leading to waste and inefficiency, and there is also the possibility that items that are longer than the specified size may fall. There was a problem with selectivity.

Therefore, the present invention takes the above drawbacks into consideration and provides a crushing equipment that automatically sorts the crushed material by particle size outside the crusher, and is highly efficient and has good sorting performance.The features of this invention are: The crusher includes an input port and a discharge port, and a primary conveyance member for conveying the crushed material discharged from the discharge port, and is located at the front of the primary conveyance member in the conveyance direction,
A sorting means is provided in which a sorting rotating body with a large number of pin groups arranged vertically and horizontally on the surface of the annular body can be freely circulated, and the tip of the conveying member in the conveying direction and the tip of the pin of the sorting means draw a circular trajectory in the scraping direction. A circulating conveyance means is provided adjacent to the conveyor section, and conveys the crushed material scraped and conveyed by a group of pins from below the conveyance end of the sorting means to the input port, and the forward end of the primary conveyance member in the conveyance direction. The secondary conveyance member is provided below the conveyance start end of the sorting means.

Hereinafter, an embodiment of the present invention will be described in detail based on the drawings. FIG. 1 shows a schematic diagram of the embodiment, and FIGS. 2 and 3 are a plan view and a front view.

1 is the next input conveyor that inputs the material to be crushed,
One end of the conveyor 1 is provided at the upper input port 3 of the crusher 2.

A primary conveyor 4 serving as a primary conveying member for conveying the crushed materials is provided at the discharge port of the crusher 2, and a sorting means is provided adjacent to the front end 5 of the conveyor 4 in the conveying direction. 6 is provided below the tip end 5 of the conveyor 4 and below the conveyance start end 7 of the sorting means 6 as a secondary conveyance member for conveying particles within specified dimensions that have been sorted by particle size. A conveyor 8 is provided, and the sorting means 6
A return conveyor 10 for conveying objects larger than a specified size is provided below the conveyance end portion 9 of the conveyor 1.
A secondary input conveyor 12 is provided from below the end portion 11 of the crusher 2 to the input port 3 of the crusher 2.

The return conveyor 10 and the secondary input conveyor 12 constitute a circulation conveyance means for conveying the pieces larger than the specified size to the crusher 2 again.

13 is a conveyor stand supporting each of the conveyors 4, 8.10 and the sorting means 6;
10 and the sorting means 6 are provided with guide side plates 14 on both sides.

The sorting means 6 has an endless belt 18 in the form of an annular body stretched between a driving roller 16 and a driven roller 17 which are pivotally supported between side frames 15 and 15.
The tension of the belt 18 can be adjusted between the belt 18 and the drive roller 16 by a motor (not shown).
8 is circulated in the direction A in FIG. The belt 18 is fixed upright, and as shown in FIG. Each bar member 19 is provided in parallel and detachably at intervals.

A group of pins 20 erected on the surface of the belt 18 constitutes a sorting rotating body.

Further, the sorting means 6 is provided with the distal end 5 of the conveyor 4 and a circular locus section 24 drawn by the tip of the pin 20 in the scraping direction close to each other, making it possible to adjust the interval therebetween. The tilt angle is also adjustable.

Since the embodiment of the present invention is constructed as described above, for example, when industrial waste such as tires is crushed and subjected to particle size separation for disposal or landfill, the waste is
Next, it is fed into the crusher 2 by the feeding conveyor 1, and after being crushed,
The crushed pieces having different sizes and shapes discharged from the discharge port are conveyed by the primary conveyor 4, and when they fall at the tip 5, the sorting means 6 selects the pieces within the specified size by the pin 20. and the pins 20, immediately fall onto the secondary conveyor 8, and are conveyed to a predetermined location by the conveyor 8.

Items larger than the specified size are scraped up by the pins 20, placed on the belt 18 on the pins 20 or between the pins 20, and fall onto the return conveyor 10 from the distal end 9 of the sorting means 6. Then, it is fed into the crusher 2 again by the secondary feeding conveyor 12 and crushed.

At this time, waste may be thrown in by the feeding conveyor 1 as needed, depending on the amount of crushed pieces within a specified size to be transported.

In the embodiment of the present invention, as described above, the sorting means 6 for sorting the particle size of the crushed material by the crusher 2 is replaced by the crusher 2.
Since it is provided outside, there is no need for a particle size screening screen inside the crusher 2.

Therefore, once crushed items are discharged to the conveyor 4 without being crushed again, there is no waste, and the degree of wear on the blades of the crusher 2 is also reduced, and maintenance is also facilitated. .

In addition, since items larger than the specified size are continuously cyclically crushed, efficiency is high and crushing can be performed one after another.

Also, the tip 5 of the conveyor 4 and the pin 20 of the sorting means 6
Since the circular locus portion 24 at the tip of the pin 20 is provided close to the pin 20, there is no possibility that items within the specified size will be scraped up by the pin 20, and the entire length of the sorting means 6 is utilized, so that the sorting performance is good.

Further, since the inclination angle of the sorting means 6 can be adjusted arbitrarily, it is only necessary to set the angle to an angle that allows efficient particle size sorting depending on the type of material to be crushed.

Furthermore, the length of the pins 20 and the pitch between the pins 20 are changed at any time according to the specified dimensions, and the tip portion of the conveyor 4 is
A large number of specified dimensions can be set by adjusting the distance between the two.

In the above embodiments, a belt conveyor is used as the sorting means 6, but the sorting means 6 may be roll-type or drum-shaped and provided with pins 20.

Further, a chute may be used instead of the secondary conveyor 8.

Also, the pins 20 may be installed one by one.
It is not limited to the examples.

As described above, the present invention has a structure in which a sorting means for sorting the particle size of the crushed material crushed by the crusher is provided outside the crusher, and the crushed material is instantly transported to a position where it falls from the tip of the primary conveying member. Particles within the specified size are not accidentally scraped up by the pins, but fall immediately and are transported to the specified location by the secondary conveyance member. Since items within the dimensions are not crushed unnecessarily many times, there is no waste, and as a result, the degree of wear on the blades of the crusher is reduced, and maintenance is also facilitated.

On the other hand, items larger than the specified size are reliably scraped up by pins, transported to a crusher by a circulation conveyance means, and are continuously crushed in circulation, so that continuous crushing can be performed one after another. Since particle size is automatically sorted in sequence, efficiency and sortability are improved.
