Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is directed to bulky waste processing equipment, waste incineration equipment,
Concerning improvements to trommel (rotary sieves) used in waste resource recovery equipment, etc.

(Prior art) In general, in bulky waste processing equipment, bulky waste is first crushed using a rotary crusher, and then the crushed waste is passed through a trommel and non-combustibles are sieved out through the holes of the trommel, thereby separating combustibles and non-combustibles. We are sorting.

In addition, in garbage incineration facilities, the problem of mercury caused by dry batteries has come to the fore in recent years, and it has come to be seen as an important pollution problem. Therefore, garbage is first sorted using a trommel, and in particular, dry batteries are placed in the holes of the trommel at the same time as non-combustible items. Attempts have been made to sort out by sieving out.

Furthermore, in garbage resource recovery equipment, garbage bags are first torn apart, then sorted with a trommel to sieve out incombustible materials such as dirt and glass pieces, and then in subsequent equipment, iron items are removed using magnets, and bottles are separated using a trommel. The materials are sorted by hand, combustibles are sorted by wind, and aluminum is separated and recovered using a linear motor type magnetic separator.

As described above, the trommel is employed in important processes in various types of equipment, and is constructed as shown in FIG. 4, for example.

That is, the trommel 20 includes a base body 21, a drum body 23 having a cylindrical shape and having a large number of holes 22,
An annular sliding portion 24 provided on the drum body 23, a receiving roller 25 provided on the base body 21 to rotate while connected to the annular sliding portion 24, a ring gear 26 provided on the drum body 23, and an annular gear 26. a pinion 27 rotatably provided on the base 21 in mesh with the pinion 27;
a rotary drive machine (not shown) connected to the input hopper 28, and a charging hopper 28 disposed on the inlet side of the drum body 23;
It consists of a suitable number of discharge hoppers 29 disposed below the peripheral surface of the drum body 23 and another discharge hopper 30 disposed below the exit side of the drum body 23.

The drum body 23 includes a ring sliding portion 24, a receiving roller 25,
It is rotatably supported by the base body 21 via a ring gear 26 and a pinion 27, and is rotated via the pinion 27 and ring gear 26 by the operation of a rotary drive machine.

The material A to be sieved, such as garbage, is input from the input hopper 28 and reaches the drum body 23, and is sieved by the rotation of the drum body 23, and fine materials to be sieved fall into the discharge hopper 29 and are , the remainder of the material to be screened falls into the discharge hopper 30.

However, in the case of such a trommel 20, if there are cables B such as wires and strings mixed in the material A to be sieved, these may be trapped in the holes 22 of the drum body 23 as shown in FIG. This often caused clogging during continuous operation.

For this reason, in the past, the operation had to be stopped periodically and this had to be removed manually.

However, such manual removal work
This was a problem because it was unsanitary and dangerous, and required a considerable amount of time and effort.

(Problems to be Solved by the Invention) The present invention was devised in view of the above-mentioned problems and to solve them, and its purpose is to:
To provide a trommel capable of preventing clogging of a hole in a drum body by removing cables such as wires and strings entangled in the hole of the drum body in an external state without relying on human hands.

(Means for Solving the Problems) The trommel of the present invention includes a base body, a drum body that is rotatable with respect to the base body and has a cylindrical shape and is provided with a large number of holes, and a drum body that is disposed close to the outer periphery of the drum body. The device is characterized in that it is constructed with a cutting device capable of cutting the cable that protrudes from the hole in the drum body.

In other words, it is a conventional trommel equipped with a cutting device.

(Function) By rotating the drum body with respect to the base body, the material to be sieved is sieved, and by operating the cutting device, the cables protruding from the holes of the drum body are cut.

When the cables are cut, they no longer become entangled with the holes in the drum body, thereby preventing the holes in the drum body from being clogged.

(Example) Next, an example of the present invention will be described based on the drawings.

FIG. 1 is a front view showing the structure of a trommel according to an embodiment of the present invention. FIG. 2 is a longitudinal side view of the same.
FIG. 3 is a perspective view of the cutting device.

The main parts of the trommel 1 include a base body 2, a drum body 3, and a cutting device 4.

The base body 2 is fixed to the installation location,
It includes H-shaped frames 5 spaced apart in the longitudinal direction.

The drum body 3 is rotatable with respect to the base body 2 and has a cylindrical shape with a large number of holes 6.

A ring sliding part 7 is provided on the inlet side (right side in FIG. 1) of the drum body 3, and a ring gear 8 is provided on the outlet side, and the ring sliding part 7 is provided on the frame 5 on the inlet side.
A receiving roller 9 is connected to and rotates, and a pinion 10 that meshes with the ring gear 8 is disposed on the frame 5 on the exit side, and the pinion 10 is connected to a rotary drive machine (not shown).

The drum body 3 is divided into three parts by the ring sliding part 7 and the ring gear 8, and the diameter of the hole 6 formed in the outer periphery of each part increases as it goes toward the exit side.

An input hopper 11 is provided on the inlet side of the drum body 3, and a discharge hopper 12 is provided below each section of the drum body 3.
Another discharge hopper 13 is located below the outlet side of the drum body 3.
are arranged respectively.

The cutting device 4 is disposed close to the outer periphery of the drum body 3 and is capable of cutting the cable B protruding outward from the hole 6 of the drum body 3.

In this example, a long fixed body 14 and a fixed body 14
A similarly elongated movable body 15 is provided to be slidable in the longitudinal direction thereof, a serrated fixed blade 16 is provided on the fixed body 14, and a serrated movable blade is provided on the movable body 15. 17, and a driving machine 18 such as a fluid pressure cylinder which is interposed between the fixed body 14 and the movable body 15 and causes them to slide relative to each other.

As shown in FIGS. 1 and 2, the cutting device 4 has a fixed blade 16 and a movable blade 17 disposed close to the outer periphery of the drum body 3, and the fixed blade 1
4 is supported on the fixed side of the base 2 or the like.

The pitch of each of the fixed blade 16 and movable blade 17 of the cutting device 4 is set to correspond to the pitch of the hole 6 of the drum body 3, and the pitch of the movable body 15 relative to the fixed body 14 is adjusted to match the pitch of the hole 6 of the drum body 3.
The sliding speed is set based on the rotational speed of the drum body 3, the diameter of the holes 6, and the pitch between adjacent holes 6 in the circumferential direction, so that one hole 6 slides at least once before passing. Leave it as is.

Next, the operation will be explained based on such a configuration.

When the rotary drive machine is operated, the rotational force is transmitted to the pinion 10 → ring gear 8 → drum body 3 →
The drum body 3 is rotated relative to the base body 2 in the direction of the arrow in FIG.

The material to be sieved A is supplied from the input hopper 11 and reaches the drum body 3, where it is sieved according to its size and discharged to each discharge hopper 12, and the remaining material is discharged to the discharge hopper 13. be done.

When the drive machine 18 is operated, the movable body 15 slides back and forth with respect to the fixed body 14, and the fixed blade 16 and the movable blade 17 are similarly operated.

Therefore, even if the cable material B, such as a wire or string, is mixed into the material A and is entangled with the hole 6 of the drum body 3, the fixed blade 16 and the movable blade of the cutting device 4 17, the outer protruding portion is cut off.
For this reason, the rope A is divided into inner and outer parts with the hole 6 as a boundary, from which they separate and fall.

Incidentally, the base body 2 and the drum body 3 are not limited to those in the previous embodiment.

The cutting device 4 is also not limited to the sliding type as in the previous embodiment.

In the previous embodiment, the cutting device 4 was provided in only one row on the outer periphery of the drum body 3, but the cutting device 4 is not limited to this.
For example, as shown by the chain lines in FIGS. 1 and 2, another row may be provided, and one row may be used for cutting wire, etc., and the other for string, etc., so that materials of different hardness can be cut specifically. In this case, the shapes of the blades of the cutting devices in the first and second rows are changed.

The blade shapes of the fixed blade 16 and the movable blade 17 are not limited to the double-edged and symmetrical shape as in the previous embodiment, for example,
It can be double-edged, asymmetrical, or single-edged.

(Effects of the Invention) As described above, according to the present invention, the following excellent effects can be achieved.
