JPH11169743A - Device for crushing and separating leftover food and sieve, drum, separator for use in the same and manufacture thereof - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a device wherein a large amount of wastes such as construction wastes, leftover foods of restaurant, domestic wastes compost of farmhouse, bark and pieces of wood of lumber mill, and sand and earth mixed into the wastes can be separated continuously into at least three kinds of materials without causing clogging. SOLUTION: A strong magnet is disposed above an intermediate part of a belt conveyor for transferring materials to be separated to prevent iron from being mixed into the materials. A net 3 is mounted in the lower part of a drum- shaped cutter 2 to separate the materials. In the drum-shaped cutter 2, cutters are arranged to allow the materials to be separated to flow easily from the front to the rear of the cutter 2. A sieve 6 is attached in the lower part at the rear of the cutter 2 and the sieve 6 is inclined to allow the materials to be separated to easily flow rearward. The angle of inclination of the sieve 6 can be adjusted depending on the kinds of the materials and an air blowing means 7 is equipped for generating an air stream obliquely downward.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention relates to construction waste, household,
A sorter that crushes and sorts miscellaneous mixed waste, including sticky waste such as food waste from restaurants, compost, bark, sawdust wood and sand, and stone from waste discharged from offices, by size and weight. .

[0002]

2. Description of the Related Art Conventionally, as a sorter of this type, there is Japanese Patent Application Laid-Open No. 7-171503. Other than this, there are trommel and vibratory separators, and various kinds of mixed waste and materials are appropriately selected for the size of screens and meshes, or sorted by size from small to large in stages. .

[0003]

Rope and tape are mixed in the waste, and the waste is wrapped during the sorting operation, and the operation must be interrupted to remove the waste. Sometimes. Also, if the leftovers or compost is wet or wet, the screen or the net may be clogged, and it may not be possible to separate powdered materials such as leftovers.

[0004] The present invention solves the above-mentioned problems of the prior art, and includes a wide range of wastes from construction waste to food left over from restaurants and household waste, compost from farmers, bark from sawmills, and wood chips. The soil and the like mixed therein can be separated into a large amount and continuously at least three stages of materials without causing clogging.

[0005]

In order to achieve the above-mentioned object, a strong magnet is attached to an intermediate upper portion of a belt conveyor for transporting an object to be sorted, thereby preventing iron from being mixed. Attach a sorting net under the drum cutter. In the drum-shaped cutter, the cutters are arranged so that the sorted material can easily flow from the front to the rear. Attach the sieve to the lower part behind the drum cutter,
The sieve has an angle of inclination so that the sorted material can easily flow backward. The angle of the sieve is configured to be adjustable by the sorting object, and is provided with an air blowing means for generating an air flow obliquely downward.

[0006]

In the sorting machine having the above-mentioned structure, a sorting object in which light and heavy materials are mixed is crushed by a drum-shaped cutter and attached to a lower portion of the center of the drum-shaped cutter. Things fall down. Objects larger than the size of the mesh, light vinyl, and the like are washed away by the rotational force of the drum-shaped cutter into the rear sorting chamber. With a sieve whose inclination angle can be adjusted up and down, large and small light materials are separated by air blowing means obliquely below the sieve, and light vinyl etc. are discharged separately.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a sorting apparatus according to an embodiment of the present invention. 1 is a side view of the present invention, FIG. 2 is a plan view of the same apparatus, FIG. 3 is a front view, and FIG. 4 is a perspective view showing the drum-shaped cutter.

FIG. 1 shows that a strong magnet is attached to the middle upper part of a belt conveyor for conveying a material to be sorted into the inlet (1) to prevent iron from being mixed. Sorted objects entered from the input port (1)
The powder is pulverized by a rotary drum-shaped cutter (2), and fines are dropped into a tray (4) by a net (3) attached to the lower center. Objects larger than the size of the mesh and light vinyl are placed in the rear sorting room by a drum cutter (2).
It is swept away by the rotational force of. The inclination angle of the sieve (6) is adjusted by the angle adjuster (5) according to the state of the sorted material. Light vinyl or the like is discharged to the outside by the air blowing means (7) obliquely below the sieve, and small and heavy leftovers fall down.

The number of blades of the drum-shaped cutter (8) is basically 30 to 50, and the number of rotations of the drum is 12 minutes per minute.
It is about 0 times, but it can be changed depending on the type of the sorting object.

[0010] The air blowing means (7) is a wind power generating device that is capable of blowing vinyl by wind power, but includes other types.

The sieve (6) basically uses a sieve that swings back and forth, but includes other types.

[0012]

As described above, according to the sorting apparatus of the present invention, the sorted objects mixed with the objects having different specific gravities can be continuously and mass-crushed and separated by the drum-shaped cutter, and the inclination angle can be reduced. The adjustable sieve and the blown air stream can separate and separate heavy and light objects.
