DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refuse treatment apparatus suitable for crushing and sacking waste of various types, sizes and shapes, and supplying the waste to an incinerator or the like in a fixed amount.

[0002]

2. Description of the Related Art Conventionally, as this type of refuse treatment apparatus for a waste incinerator, there is one disclosed, for example, in Japanese Patent Publication No. 63-034084. The apparatus disclosed in this publication includes a plurality of feeders formed with a plurality of transport blades formed at intervals along one side edge of a straight plate so that the transport blades are on the upper side. It is connected to every other or a plurality of groups and divided into two groups (hereinafter, referred to as a first feeder group and a second feeder group, respectively). Below these feeder groups, the first and second feeder groups are mutually connected. A drive device having a parallel motion mechanism with a gear train that makes a circular motion (hereinafter referred to as a walking motion) in a state parallel to the longitudinal direction of the feeder with a phase difference of 180 degrees is disposed, and discarded by the walking motion of the transport blade of each feeder. We are trying to transport things. Further, a machine frame facing the transport blade side of the feeder at such a small interval that the transport blade does not come into contact is provided, and a cutter is provided on the transport blade side of the machine frame at a position between the feeders. A hopper for supplying waste is provided above the rear end of the feeder line.

In such a configuration, when the first and second feeder groups walk, the first and second feeder groups are 180 degrees out of phase with each other. When it is at a certain position, the transport blades of the other feeder group are at positions shifted by 180 degrees in the same plane when viewed from the feeder plate overlapping direction. The first feeder group is arranged in the same plane when viewed from the feeder plate overlapping direction, and the positions of the respective transport blades also match. Also, the second feeder group is arranged on the same plane as viewed from the feeder plate overlapping direction at a position 180 degrees out of phase with the first feeder group, and the positions of the respective transport blades also match.

[0004] Assuming that the transport blades of the first feeder group are located at the rear position in the horizontal plane passing through the rotation center point in the circular motion locus, the transport blades of the second feeder group are shifted forward by 180 degrees in the same horizontal plane. , And the transport blades of the first and second feeder groups are all at the same height. From this state, 9
When the transport blades of the first feeder group are at the highest point in the circular motion locus after rotating by 0 degrees, the transport blades of the second feeder group are at the lowest point in the circular motion locus. In this state, the transport blades of the first feeder group protrude above the upper ends of the transport blades of the second feeder group, and the transport blades of the second feeder group sink into the plate area of the first feeder group.

When the transport blades of the first feeder group are further rotated by 90 degrees to the front position in the horizontal plane, the transport blades of the second feeder group are shifted rearward by 180 degrees in the same horizontal plane, so that the first and second feeders are shifted. Each of the transport blades of the second feeder group is at the same height position. Rotate 90 degrees further from this state,
When the transport blade of the second feeder group is located at the highest point in the circular motion locus, the transport blade of the first feeder group is at the lowest point in the circular motion locus, and the transport blade of the second feeder group is moved. The transport blades of the first feeder group protrude upward from the upper ends of the transport blades of the first feeder group, and sink into the plate area of the second feeder group.

Therefore, the waste put in from the hopper at the rear end of the feeder line is moved by the walking motion of the first and second feeder groups, and the first 180-degree rotation is caused by the action of the transport blades of the first feeder group. In the next 180-degree rotation, the paper is sequentially conveyed to the front of the feeder line by the action of the conveying blade of the second feeder group. At this time, the transport blade passes between the cutters,
The waste is sandwiched between the transport blade and the cutter while being sent in an arc shape, is cut and crushed by the cutter blade by the shearing action of the transport blade and the cutter, and the bag is broken. The crushed or crushed waste is transported forward by a predetermined amount by the space separated by the feeder and the cutter, dropped from the end of the feeder line, and introduced into the incinerator through the discharge port.

[0007]

Generally, wastes of various types, sizes and shapes are included. However, in the above-described conventional waste incinerator refuse treatment apparatus, not only is the interval between the feeder transport blade and the machine frame limited, but a cutter is provided in a portion located in a gap between the feeders. Therefore, if the distance between feeders, the distance between feeders and cutters, or the distance between feeders and machine frames is larger than the distance between feeders, In addition, an excessive load is generated on the apparatus, and the apparatus is inevitably damaged or stopped, and it is difficult to quantitatively supply refuse.

Further, the feeder plates constituting one feeder group are collectively eccentrically connected to the shafts of at least two gears of the gear train for driving the feeder by connecting rods below the transport section. As a result, the feeder group makes a circular motion in a state parallel to the line direction. For this reason, fine dust falling from the gap between each feeder plate may enter between the connecting rod and the feeder plate,
There is a problem that a large load is partially applied to damage the bearing.

A technical problem of the present invention is that when an excessive load is applied to a feeder, the load can be absorbed and reduced, and a fixed amount of waste can be smoothly supplied, and the drive system of the feeder can be disposed of. Is to be able to suppress entanglement.

[0010]

According to a first aspect of the present invention, there is provided a waste disposal apparatus for a waste incinerator having the following configuration. That is, a plurality of feeders each having a plurality of transport blades formed on one side surface of the plate at intervals in the longitudinal direction are arranged in parallel such that the transport blades are on the upper side, and every other plate-like feeder or a plurality of feeders are provided. The waste is conveyed by making a circular motion in a longitudinal direction parallel to the feeder with a phase difference of a predetermined angle by a drive device having a parallel motion mechanism by connecting these feeder groups into a plurality of groups. In the waste incinerator refuse treatment apparatus, the formation position of the transfer blade is limited to the forward end of the feeder plate in the transfer direction, and the feeder plate is set so that at least the transfer blade portion is inclined downward with respect to the horizontal plane. A hopper for supplying waste to the transport blade portion is provided above the transport blade portion of the feeder, and is substantially the same as the transport portion width direction above the transport outlet portion of the feeder. By the way, the inclination with respect to the horizontal plane has a dust contact surface set at a larger angle in the same direction as the conveying blade part inclination direction, and the nose hardware whose height can be adjusted in the vertical direction, at least the nose hardware of the feeder. At the opposing position, a large-sized transport blade larger than the transport blade is provided. According to the first aspect of the present invention, the waste supplied from the hopper to the transport blade portion inclined downward at the tip of the feeder plate is moved to the transport outlet portion by a circular motion in the feeder longitudinal direction having a phase difference of each feeder group. The nose piece is crushed and broken by a large transfer blade immediately before the exit of the narrowed short path between the feeder and the nose metal which is directly connected to the transfer outlet, and immediately after that, it is dropped from the feeder transfer outlet. Into the incinerator through the outlet. Since the height of the nose metal can be adjusted in the vertical direction, the nose height, which is the shortest distance between the feeder and the contact surface of the nose metal, can be set freely according to the properties of the waste. For this reason, an optimal nose height can be obtained, and the effect of smooth supply, crushing, and bag breaking of waste is improved. Further, the large transport blade provided at least at the position facing the nose metal of the feeder, that is, at the portion closest to the transport outlet of the feeder can ensure the crushing and bag breaking effects.

According to a second aspect of the present invention, there is provided a waste treatment apparatus for a waste incinerator, wherein the parallel movement mechanism of the drive device is disposed at a rear portion of the feeder plate remote from the transport blade portion, and has a cantilever structure. It was done. According to the second aspect of the present invention, since there is no connecting portion between the driving device and the feeder below the contact portion of the feeder with the waste, the waste dropped from the gap of the feeder enters between the feeder and the connecting rod. This eliminates the conventional trouble caused by the clogging of falling waste.

Further, according to a third aspect of the present invention, there is provided a refuse disposal apparatus for a waste incinerator, wherein a nose tip blade is provided on a transfer outlet side of a nose metal piece so as to be located on an extension of the refuse contact surface. It is. According to the third aspect of the present invention, the nose tip blade which is located on the extension of the dust contact surface of the nose hardware and is provided on the side of the transport outlet thereof is capable of crushing and breaking the bag between the nose hardware and the feeder. When ejected from the transport outlet of the feeder, it is prevented from scattering upward. Therefore, the waste discharged from the transport outlet can be smoothly guided downward.

Further, in the refuse treatment apparatus for a waste incinerator according to claim 4 of the present invention, one or more large-sized transport blades larger than the transport blade are newly provided in the middle of the transport blade portion.
In the invention according to the fourth aspect, the crushing and bag breaking effects can be further improved by the large carrying blade in the middle of the carrying blade portion.

According to a fifth aspect of the present invention, there is provided a waste disposal apparatus for a waste incinerator, wherein the thickness of the feeder plate, which is the width of the feeder, is set to 60 to 200 mm, and the diameter of the circular motion of the feeder is set to 50 to 200 mm. It was done. According to the fifth aspect of the present invention, the waste transfer efficiency is 18
Depending on the spacing between the feeders with a phase difference of 0 degrees and the radius of gyration of the vertical movement of the feeders, these dimensions are determined by the size of the waste input into the apparatus. The waste to be put into the waste incinerator contains many non-combustible materials and non-combustible materials, such as futons, vinyl sheets, etc., and the average diameter of the minimum value of the thickness is 60 mm. . Therefore, when the thickness of the feeder plate, which is the width of the feeder, is 60 mm or less, the difficult-to-treat object having a diameter of about 60 mm and oriented in the longitudinal direction of the feeder plate is a tenon in each of the feeder groups that are moving in a mortise group in a circular motion. When the condition occurs, the right and left feeder plates are pushed down, and the feeder is damaged. On the other hand, the representative diameter of 90% or more of the waste for incineration is less than 200 mm. Therefore, when the thickness of the feeder plate is 200 mm or more, the waste is stored in a single feeder plate and is placed on the feeder plate. Transport efficiency is reduced. The main components of incineration waste are kitchen garbage, vinyl garbage, and paper garbage.
These waste clumps are pushed to 50mm
Dent, and that amount of waste escapes left and right. For this reason, if the vertical movement height of the feeder is 50 mm or less, even if the feeder rotates, the transfer efficiency decreases due to the deformation of the waste. On the other hand, when the diameter of the rotational motion of the feeder is 200 mm or more, the feeder drive shaft and its bearings become large, and it becomes difficult to manufacture a waste incineration apparatus for waste incineration with realistic dimensions.

According to a sixth aspect of the present invention, there is provided a waste disposal apparatus for a waste incinerator, wherein the connecting portion between the drive shaft bearing of the feeder and the feeder allows the transport blade portion to swing downward when overloaded. It is provided with a shock absorber. In the invention according to claim 6, the shock absorber provided at the connecting portion between the drive shaft bearing of the feeder and the feeder is provided with leverage when a large load, such as metal, incombustibles, or the like, is supplied with a conveyed material having a large operating load. According to the principle, the shock absorber contracts (or expands) to allow downward swinging of the feeder transport blade portion, thereby preventing a load exceeding a certain level from being applied to the feeder and its driving unit. Therefore, it is possible to prevent the feeder from being damaged or stopped due to trouble.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. FIG. 1 is a longitudinal sectional view schematically showing the configuration of a waste incinerator waste treatment apparatus according to the present embodiment, and FIG.
FIG. 3 is a cross-sectional view taken along the line AA of FIG.

In the refuse treatment apparatus 7 according to the present embodiment, as shown in the drawings, a hopper 3 for charging or storing the waste 2 at one end upper portion of the casing 1 and a crushed and bagged waste 2 at the lower portion. Outlet chutes 4 are provided, respectively, and a plurality of feeders 6 each formed of a V-shaped plate 5 are arranged in parallel between a lower portion of the hopper 3 and an upper portion of the outlet chute 4.

The feeder 6 has, on one side surface of a piece 5a of the V-shaped plate 5, a plurality of transport blades 8 having a right angled triangular cross section at intervals in the longitudinal direction. It is formed in a cutter-shaped large-sized transport blade 8A that is larger than the other transport blades 8 and has a crushing / bag-breaking action.
The feeders 6 are arranged side by side such that the transport blades 8 and 8A are on the upper side, and the transport blades are arranged so as to be inclined downward with respect to the horizontal plane and below the hopper 3. Is set.

Above the transport outlet at the tip of the feeder 6, the inclination with respect to the horizontal plane is substantially the same length as the width of the transport section, and is set at a greater angle in the same direction (downward tilt) as the inclined direction of the transport blade. A nose hardware 11 having a dust contact surface 9 and capable of adjusting the height in the vertical direction is provided, and the large-sized transport blade 8A is disposed at a position facing the nose hardware 11. Therefore, by adjusting the height of the nose hardware 11, the nose height, which is the shortest distance between the feeder 6 and the nose hardware 11, can be adjusted.

In addition, on the transport exit side of the nose hardware 11,
The nose tip blade 1 is located on the extension of the dust contact surface 9.
1a, the nose tip blade 11a scatters upwards when the waste 2 crushed and broken between the nose hardware 11 and the feeder 6 is discharged from the transport outlet of the feeder 6.
It can be suppressed by.

Each of the feeders 6 is connected to every other or a plurality of the other feeders 6 in a horizontal arrangement separated from the transport blade portion of the V-shaped plate 5 to the feeder 6 by two groups (hereinafter referred to as "each group"). 1st feeder group, 2nd feeder group)
And a gear train 12 for transporting the waste 2 by causing the first and second feeder groups 6A and 6B to perform circular motion (hereinafter referred to as walking motion) in a state parallel to the longitudinal direction of the feeder with a phase difference of 180 degrees. , A driving device 14 having a parallel motion mechanism 13 is arranged to have a cantilever structure.

This will be described in further detail.
Are mounted on a gear train 12 in a meshing relationship with each other, a feeder drive shaft 15 composed of eccentric shafts attached to every other gear train 12 with a phase difference of 180 degrees, and another piece 5b of each feeder plate 5. The feeder 6 comprises a feeder drive shaft bearing 16 attached to an edge, and each feeder 6 is connected to each other by a feeder drive shaft 15 at every other or every other position via the feeder drive shaft bearing 16 so as to be relatively rotatable. Divided into groups.

One of the gear trains 12 is a drive gear 12a, and the feeder drive motor 1
When the drive gear 12a is disturbed, all the gears rotate in conjunction with each other, and the first and second feeder groups 6 are rotated.
A and 6B are rotationally driven in the same direction with a phase difference of 180 degrees, and perform a walking motion (parallel motion).

As shown in FIGS. 1 and 3, the feeder drive shaft bearing 16 has a bearing portion 16a slidably mounted in the frame 16b in a vertically slidable manner. Between the upper edge of the plate 5 and a buffer device 19 made of a coil spring is installed. Accordingly, when a transported object such as large dust, metal, incombustible material, or the like having a large operating load is supplied to the transport blade portion of the feeder 6, the buffer device 19 contracts (or expands) by the leverage principle.
Thus, the transport blade portion is allowed to swing downward, so that a load exceeding a certain level can be prevented from being applied to the feeder 6 and its driving portion.

Further, the first and second feeder groups 6A, 6B
A dust conveyor 21 is provided below the conveying unit for conveying the fine waste 2 dropped from the gap between the feeders to the outlet chute 4 by a scraper, and is driven at a constant speed by a motor 22 for driving the dust conveyor. It has become.

In the apparatus of this embodiment having the above-described configuration, the thickness of the feeder plate 5, which is the width of the feeder 6, is set to 60 to 200 mm, and the diameter of the circular motion of the feeder 6 is set to 50 to 200 mm. The reason is as follows.

That is, the transfer efficiency of the waste 2 is 180
Depending on the distance between the feeders 6 with a phase difference of degrees and the radius of gyration of the vertical movement of the feeders 6, these dimensions are determined by the size of the waste 2 put into the apparatus. The waste 2 to be put into the waste incinerator contains a large number of hard-to-crush materials with incombustibles and square materials, as well as many hard-to-break bags such as futons and vinyl sheets.
0 mm. Therefore, when the thickness of the feeder plate 5 serving as the feeder width becomes 60 mm or less, the difficult-to-treat object having a diameter of about 60 mm and facing the longitudinal direction of the feeder plate 5 makes a circular movement in a tenoned state. When the mortise state of the second feeder group 6A, 6B occurs, the second feeder group 6A gets stuck and pushes the right and left feeder plates 5, thereby causing the feeder 6 to be damaged.
On the other hand, the representative diameter of 90% or more of the waste 2 for incineration is 200
mm, the feeder plate 5 has a thickness of 200
mm or more, the waste 2 becomes a single feeder plate 5
The feeder plate 5 is placed inside the feeder plate 5, and the chance of contact with the transport blades 8 and 8 </ b> A of the adjacent feeder 6 is reduced, and the transport efficiency of the waste 2 is reduced.

The main components of the waste 2 for incineration are kitchen refuse, vinyl refuse, and paper refuse.
The lump is recessed by about 50 mm by being pushed, and the waste 2 of that amount escapes right and left. For this reason, if the vertical movement height of the feeder 6 is 50 mm or less, even if the feeder 6 rotates, the transport efficiency is reduced due to the deformation of the waste 2.
On the other hand, if the diameter of the rotational movement of the feeder 6 is 200 mm or more, the feeder drive shaft 15 and its bearing 16 become large, and it is difficult to manufacture a waste incineration apparatus for waste incineration with realistic dimensions.

Next, the operation of the apparatus of this embodiment will be described with reference to FIG.
3 through FIG. First, when operating this apparatus, the height position of the nose hardware 11 is adjusted and the feeder 6 is adjusted.
The nose height, which is the shortest distance between the nose and the nose hardware 11, is adjusted to a height that matches the properties of the collected waste in the area. Next, the feeder driving motor 18 is started to drive the gear train 12.
Is rotated to cause the first and second feeder groups 6A and 6B to start walking. First and second feeder groups 6A, 6B
Are 180 degrees out of phase with each other, so that when the transport blades of one feeder group are at a certain position, the transport blades of the other feeder group are at a position shifted by 180 degrees in the same plane when viewed from the feeder plate overlapping direction. is there. The first feeder group 6A is disposed in the same plane as viewed from the feeder plate overlapping direction, and the positions of the respective transport blades 8 and 8A also coincide. Further, the second feeder group 6B is also the first feeder group 6A.
At a position 180 degrees out of phase with each other, they are arranged in the same plane when viewed from the feeder plate overlapping direction, and the positions of the respective transport blades 8 and 8A also match.

Now, each of the transport blades 8, 8 of the first feeder group 6A
Assuming that A is at the rear position in the horizontal plane passing through the rotation center point in the circular motion locus, each transport blade of the second feeder group
The transport blades 8 and 8A of the first and second feeder groups 6A and 6B are located at the same height position at the front position within the same horizontal plane shifted by 0 degrees. From this state, when the conveying blades 8 and 8A of the first feeder group 6A are rotated to 90 degrees to reach the positions of the highest points in the circular motion locus, the conveying blades 8 and 8A of the second feeder group 6B are moved It is the position of the lowest point in the circular motion trajectory (FIG. 1). In this state, the transport blades 8, 8A of the first feeder group 6A project above the upper ends of the transport blades of the second feeder group 6B, and the transport blades 8, 8A of the second feeder group 6B.
Sinks into the plate area of the first feeder group 6A.

Further, the first feeder group 6 is rotated by 90 degrees.
When the transport blades 8, 8A of A are located at the front position in the horizontal plane, the transport blades 8, 8A of the second feeder group 6B are located at the rear position in the same horizontal plane shifted by 180 degrees, and the first and second feeder groups 6A are shifted. , 6B are located at the same height. When the conveying blades 8 and 8A of the second feeder group 6B are further rotated by 90 degrees from this state to the position of the uppermost point in the circular motion locus, each of the conveying blades 8 and 8A of the first feeder group 6A becomes It becomes the position of the lowest point in the circular motion locus, and each of the transport blades 8 and 8A of the second feeder group 6B protrudes above the upper end of each of the transport blades of the first feeder group 6A, and each of the transport blades 8 of the first feeder group 6A. , 8A sink into the plate area of the second feeder group 6B.

Therefore, the waste 2 introduced from the hopper 3 at the front end of the feeder line is inclined by the first 180 ° rotation of the first feeder group 6A due to the walking motion of the first and second feeder groups 6A and 6B. Each arranged transport blade 8, 8
By the action of A, the second feeder group 6 in the next rotation of 180 degrees
By the action of each of the transport blades 8 and 8A which are inclined and arranged at B, the transport blades are smoothly transported sequentially forward of the feeder line. When passing between the nose fitting 11 and the large carrying blade 8A, the waste 2 is sent in an arc shape while the large carrying blade 8A and the nose fitting 1
1 and is cut and crushed by the large conveying blade 8A, and the bag is broken. The crushed or crushed waste 2 is transported forward by a predetermined amount by the space separated by the feeder 6 and the nose metal piece 11, drops from the transport outlet at the end of the feeder line, and is incinerated through the outlet chute 4. Charged into the furnace. At this time, the waste 2 discharged from the transport outlet and trying to scatter upward is restrained from moving upward by the nose tip blade 11a above the transport outlet, is guided downward and smoothly enters the outlet chute 4. Fall.

In the present embodiment, the waste 2 input from the hopper 3 as described above is crushed or broken by the feeder 6 and discharged into the outlet chute 4 from the transport outlet. Then, during normal operation, as shown by the imaginary line in FIG. 3, the feeder 6 transports the waste 2 while crushing or breaking the bag while the nose height is almost maintained at the initial setting height.

When the operation load of large refuse, metal, incombustibles, etc. is larger than that of the hopper 3, the feeder 6 contracts (or expands) according to this principle as shown by the solid line in FIG. ) To allow downward swinging of the feeder transport blade portion, thereby preventing a load exceeding a certain level from being applied to the feeder 6 and its driving section.

In the apparatus of this embodiment, since the driving device 14 having the parallel movement mechanism 13 by the gear train 12 is arranged on the other piece 5b remote from the conveying blade portion of the feeder plate 5, There is no connecting portion between the drive unit 14 and the feeder 6 below the contact portion with the waste 2, and the waste 2 dropped from the gap of the feeder 6 is fed to the feeder drive shaft bearing 1.
There is no clogging of 6th grade, and no trouble due to clogging of falling trash occurs.

In the above-described embodiment, the large transport blade 8A is used.
