Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facility for sorting wastes containing iron scraps, concrete scraps, paper scraps, etc. according to their weight and the presence or absence of magnetism.

[0002]

2. Description of the Related Art Conventionally used waste sorters include a magnetic type for sorting magnetic substances and a sieve type for sorting by the size of waste after crushing. However, in most of these and the apparatus in which these are combined, the waste is sorted while being laterally moved.

[0003] At the construction site, waste is generated by mixing concrete debris, iron waste, paper waste, etc., and it is sorted into combustibles, incombustibles, metals, etc. at the site. Is being considered for recovery.

[0004]

However, in the above-mentioned conventional sorting machine, since the waste is moved laterally for sorting, a large area is required for installing the machine, and it is necessary for a construction site or the like. There is a problem that it is difficult to secure a place to put such a sorter. The present invention is
The present invention is intended to solve such a problem, and an object thereof is to provide a waste sorting facility that does not require a large area for installation and can be used at a construction site or the like.

[0005]

In order to achieve the above object, the waste sorting facility of the present invention comprises an input port into which waste is input, a drop path connected to the input port and extending downward. A first branch path and a second branch path that are branched into two at the lower end of this drop path and extend downward, and a third branch that is further branched into two at the lower end of at least one of these branch paths and extend downward. A branching path and a fourth branching path are provided, and one of the branching positions is provided with a weight sorting device that sorts the waste into two types by weight and drops the wastes into separate branching paths, and the other has magnetism. Is provided with a magnetic sorting device for sorting the waste into two types and dropping them into separate branch paths.

[0006]

The waste that has been introduced from the inlet drops down the fall path to the lower end thereof, is sorted into two types by the sorting device provided here, and falls into the first branch path and the second branch path, respectively. .. Of these branch routes, the waste that has fallen to the side where the lower end is further divided into two is further sorted into two types by a sorting device provided at the lower end of this branch route, and the third branch route and the fourth branch route. It falls to the branch path and respectively. Since one of the sorting devices is a weight sorting device and the other is a magnetic sorting device, the waste is sorted into at least three types according to weight and presence / absence of magnetism.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 is a schematic view showing an embodiment of the present invention, and FIG. 2 is an enlarged view of a portion A of FIG. As shown in FIG. 1, an opening at the upper end is used as an input port 1, and a rectangular tube extending obliquely downward from here, the tip of which is bent and further extends vertically downward constitutes a drop path 2 of the present invention. .. The input port 1 is provided with a crusher 3, which crushes the waste to be input into a size such that it can smoothly drop in each path of this equipment. The crusher 3 includes a lower blade member 3a provided on the upper end surface of the charging port 1 and an upper blade member 3b meshing with the lower blade member 3a, which is rotatably supported by a shaft 3d. The waste is crushed by pushing it down toward the inlet 1 by hand or by moving it with a pushing device using power.

The lower end of the drop path 2 is branched into a first branch path 4 formed of a rectangular tube extending obliquely downward and a second branch path 5 extending vertically downward from the drop path 2. An enlarged view of this branch position is shown in FIG. FIG. 4 is a sectional view taken along line BB of FIG. At this branch position, as shown in FIG.
One end of several spring bars 6 is fixed to one side surface of the rectangular tube, and the free ends thereof are extended obliquely downward so as to follow the inclination of the lower side surface of the rectangular tube forming the first branch path 4 and the fall path. Two
And the second branch path 5 are separated. The spring bar 6 is made of a thick steel wire in a shape such that its tip becomes thin, and always holds the inclination.

The spring bar 6 arranged in this way
Corresponds to the weight selection device in the present invention. That is, when a large amount of waste 7 falls and the spring bar 6 is weighted more than a predetermined amount, the spring bar 6 bends in the middle part to lower the tip end as shown by the imaginary line in FIG. The waste 7 is dropped onto the second branch path 5. Further, as shown in FIG. 5, air or water injection nozzles 19 and 20 are attached to positions immediately above or slightly below the fixed position of the spring bar 6 so as to remain on the spring bar 6 or between the spring bars 6. By blowing off the small weight waste sandwiched between the two with jetted air or water, or by bending up the spring bar 6 and blowing up the small weight waste that is about to fall together with the large weight waste that is falling. It is also possible to employ a mechanism for directing a small amount of waste to the first branch path 4.

The lower end of the second branch path 5 is further divided into two, a third branch path 8 and a fourth branch path 9. As can be seen from FIG. 2, at this branching position, a pulley 10 made of a magnetic material and a pulley 11 made of a non-magnetic material are arranged with a predetermined gap, and a belt 12 is passed over them to form a magnetic sorting device 13. Is attached. The pulley 10 made of a magnetic material has a shaft 10a that rotates integrally with the second branch path 5 at a position on the boundary line between the second branch path 5 and the third branch path 8 so as to rotate freely on two opposite side surfaces of the rectangular tube. It is attached by supporting. The pulley 11 made of a non-magnetic material is located above the pulley 10 so that the belt 12 passed over the pulley 11 and the pulley 10 inclines toward the third branch path 8 at the same inclination as the spring bar 6. , And the shaft 11a is attached in the same manner as the pulley 10. The belt 12 having a predetermined width on both pulleys
Are passed endlessly.

When the pulleys are rotated by the power source connected to either of the shafts 10a or 11a or the weight of the waste placed on the belt 12 to move the belt 12 in the direction of the arrow, the belt 12 is moved. The waste 14 that has fallen onto the belt 12 moves on the belt 12 in the direction of the arrow. Here, if this waste material 14 is a magnetic substance, when it reaches the pulley 10, it is attracted by the magnetic force to the pulley 10 made of a magnetic material via the belt 12 (14a), and is inverted and wraps around the lower side of the pulley 10. (14b). Then, when the waste 14 b leaves the pulley 10 due to the movement of the belt 12, the waste 14 b drops from the belt 12 toward the fourth branch path 9.

A large number of chains 15 are hung in the shape of goodwill on the lower side surface of the opening of the rectangular tube forming the first branch path 4, and the waste 14 that has fallen by bending the spring bar 6 hits the belt 12 and jumps. If this happens, hit this. This chain 15 is the waste 1
It serves to absorb the impact of No. 4 and return the waste 14 to the belt 12. As a result, the waste 14 is transferred to the belt 1
It is prevented that the vehicle falls directly into the third branch path 8 without being guided by 2.

A collection box 1 is provided below each branch path.
6, 17, and 18 are installed, and the separated wastes are collected. Waste that has been crushed by the crusher 3 as necessary and then input from the input port 1 falls through the drop path 2 and reaches the first branch position where the spring bar 6 is installed. Light paper such as paper waste, wood waste, and film do not push down the spring bar 6,
It slides down and goes to the first branch route 4. Heavy objects such as concrete debris, pottery, thick plastic, and iron scraps push down the spring bar 6 and fall into the second branch path 5. At this time, among the wastes that have been thrown in, heavy concrete scraps and the like fall down the drop path 2 first, and small waste paper scraps and the like fall later,
The concrete and the waste paper will not fall on the spring bar 6 in a state where they adhere to each other.

The waste material 14 entering the second branch path 5 falls onto the belt 12, but if the waste material 14 is a magnetic substance such as iron, it is guided by the belt 12 and is made of a magnetic material. Belt 12 when reaching pulley 10
Is attracted to the pulley 10 via. Then, the waste 14a is guided by the belt 12 and moved,
It turns around and turns downward, falls from the belt 12 at a position away from the pulley 10, and heads toward the fourth branch path 9. If the waste material 14 on the belt 12 is a substance having no magnetism, the waste material 14 is guided by the belt 12 and is dropped from the tip to the third branch path 8 without being attracted to the magnetic pulley 10.

In this way, the wastes sorted into the respective branch routes are collected in the collection boxes placed below the respective branch routes. That is, waste paper, wood chips, films and the like are in the recovery box 16 below the first branch path 4, and concrete debris, pottery, thick plastic, etc. are in the recovery box 17 below the third branch path 8. But the fourth branch route 9
Iron scraps and the like are collected in the collection box 18 below.

Although the equipment of the present invention is usefully used in a construction site, etc., if the dust chute 21 is installed and the sorting equipment of the present invention is connected to the lower portion thereof as shown in FIG. It is convenient because it can be put into the loading port 22 on each floor and sorted and collected without being taken out. In the above embodiment, a weight sorter is provided at the first branching position to sort the waste by weight first, and a large weight is further sorted by the magnetic sorter according to the presence or absence of magnetism. The order is not limited to this, and the installation positions of the sorting devices may be reversed. Further, the weight sorting device and the magnetic sorting device are not limited to those described above. In addition, the first branch path 4 may be further branched to provide a sorting device similar to the above or another sorting device to sort into four types.

In the sorting apparatus of the present invention, if waste containing a mixture of iron waste, concrete debris, waste paper, etc. is fed through the inlet 1 provided above, the waste can be separated and collected in the downward direction. However, it can also be used as a feeding path for the waste that has been separated and collected in advance.

[0018]

As described above, according to the present invention, the waste introduced from the input port is divided into two by the first sorting device after being dropped in the drop path and further moved downward. , One of which is further divided into two by the next sorting device and falls. Since one of the sorting devices is a weight sorting device and the other is a magnetic sorting device, the waste is sorted in at least three types according to weight and presence / absence of magnetism while being moved in the vertical direction. As described above, since the sorting equipment of the present invention sorts waste while moving it in the vertical direction, it can be usefully used in places where it is difficult to secure a place for placing equipment, such as a construction site. ..
