Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a garbage treatment device for removing garbage in waterways.

[Conventional technology]

Conventionally, as shown in Japanese Patent Publication No. 59-4005, a plurality of garbage retaining rods each having a V-shaped cross section in a direction perpendicular to the water flow direction are arranged side by side at intervals. A garbage locking body consisting of a plastic bag is provided in the waterway, a hollow section is provided below the garbage locking body separated from the inflow side of the waterway, and the outflow side of the waterway is connected to this hollow part. There is a garbage processing device in a waterway in which a dust collecting body that has water permeability and can be taken out from underwater is exposed to the downstream end of a garbage retaining body. According to this conventional device, the garbage in the waterway moves along the upper surface of the locking rod, and at that time, the garbage moves along the V
Since the debris retaining rod with a shaped cross-section floats and slides due to the reverse upward flow, it does not get entangled with the retaining rod and cannot be removed, so the retaining body becomes clogged with debris. There is little risk of this happening, and garbage can continue to be removed normally. The dust is then taken out from the water by the dust collector.

[Problem that the invention attempts to solve]

As described above, the above-mentioned conventional device is more effective than previous similar dust removal devices in terms of preventing clogging caused by dust, but it cannot be said to be completely effective. For example, it is difficult for the reverse upward flow due to the V-shaped cross section of the garbage retaining rod to act effectively on long and thin rod-shaped garbage such as tree branches. If it gets into the gap between it and the stopper rod, it may get caught in the gap and become impossible to remove.Furthermore, in such a case, there is a risk that paper scraps and the like will get caught in the stick-shaped garbage, increasing the clogging.

The purpose of the present invention is to more effectively prevent the possibility of clogging of a garbage locking body consisting of a plurality of garbage locking rods with a V-shaped cross section, and to prevent elongated rod-shaped underwater debris from getting caught in the gaps between the locking rods. The purpose is to eliminate the fear that it will not come off.

[Means for Solving the Problems] The present invention provides a plurality of garbage retaining rods 3a and 3b each having a V-shaped cross section in a direction perpendicular to the water flow direction through a gap 4. Garbage locking bodies 2 arranged in parallel are provided in the waterway, and this garbage locking body 2
A hollow part 24 is provided below the inflow side part 23 of the waterway, and the outflow side part 34 of the waterway is connected to this space part 24, and the downstream end 8 of the garbage retaining body 2 is connected to the hollow part 24. In a garbage processing device in a waterway in which a dust collector 33 that has water permeability and is removable from underwater is exposed, the plurality of garbage retaining rods 3a, 3b are provided.
This is a configuration in which all the upstream ends 7 are arranged at the same height, and the adjacent downstream ends 8 are arranged alternately in upper and lower stages.

[Effect]

The present invention has the above-mentioned V-shaped cross-section garbage retaining rods 3a, 3.
The dust floating up due to the reversed upward flow in b flows smoothly downstream along the dust locking rods 3a and 3b in the water flow direction, and is captured by the dust collector 33, and this dust collector 33 above the water and remove the garbage from the water. Among the garbage, long and thin rod-shaped garbage is partially attached to the locking rod 3a and the locking rod 3b.
However, the gap 4 between the locking rods 3a, 3b gradually increases as you go forward between the adjacent locking rods 3a, 3b. Since it tends to gradually expand, the rod-shaped debris that has entered the gap 4 becomes loosely fitted to the gap 4 as it is swept away, and smoothly moves to the dust collector 33 along the locking rods 3a and 3b.

〔Example〕

Next, one embodiment of the present invention will be described based on the drawings.

Place the garbage retainer 2 in the waterway 1 against the bottom of the waterway 1.
Install at a gentle slope of 15° or less.

This garbage locking body 2 includes a plurality of garbage locking rods 3a, 3b arranged in parallel on front and rear support frames 5a, 5b with a gap 4 in between, and each of the garbage locking rods 3a. , 3b has a V-shaped cross section in a direction perpendicular to the water flow direction, and therefore has a V-shaped groove 6 formed on its upper surface.

Each of the above-mentioned garbage retaining rods 3a, 3b has all its upstream ends 7 directly welded onto the upstream support frame 5a as shown in FIG. They are arranged at the same height, and the downstream end 8 of every other locking rod 3a is welded to the downstream side support frame 5b via a support member 9, as shown in FIG. At the same time, by directly welding the remaining locking rods 3b onto the lower support frame 5b, their adjacent downstream ends 8 are arranged alternately in upper and lower stages. As a result, the gap 4 between the mutually adjacent locking rods 3a, 3b becomes slightly stepped toward the downstream side.

In addition, to support this garbage retaining body 2, pillars 11 are erected at the front and rear sides of both sides of the waterway 1, and the pillars 11 at the four corners are
Pulleys 12 and 13 are provided at the upper end, and a winch 14 is provided at the upper end of the front and rear columns 11 on one side, and two wires 15 and 16 are wound around each winch 14, and one wire The wire 15 is wound around the pulley 12 on one side and then pulled out downward, and the other wire 16 is wound around the pulley 13 on the other side and then pulled out downward. , 5b, the lower ends of the wires 15, 16 at the four corners are respectively connected to the upper ends of the support plates 17 rotatably attached to both ends of the wires 15, 5b.

Then, for example, by rotating the handle 18 of the front winch 14, the wires 15, 1 on both sides of the front
6 are equally wound up or rewound, the front side of the dust stopper 2 moves up and down, and the overall inclination angle changes. Also, if both winches 14 are rotated equally, the wires 15 at the four corners, 16 are operated equally, and the garbage retaining body 2 moves up and down in parallel. Therefore, the inclination or vertical movement of the garbage retaining body 2 can be adjusted depending on the situation of the place where the garbage retaining body 2 is installed.

Further, a closing plate 21 is rotatably supported on the upstream end of the garbage retaining body 2, and the lower end of this closing plate 21 is connected to the water channel 1.
By coming into contact with the convex portion 22 on the bottom surface of the garbage retainer 2 under its own weight, a hollow portion 24 is provided below the garbage retaining body 2, which is separated from the inlet side portion 23 of the water channel. Note that even if the garbage retaining body 2 moves up and down a little, the closing plate 2
1 moves up and down without leaving the convex portion 22.

In addition, a water-permeable dust collector 33 formed by providing a punching metal plate 31 in a frame 32 faces the downstream end 8 of the dust retaining body 2, and this dust collector 3
3 to form an outflow side 34 of the waterway relative to the inflow side 23 of the waterway, and connect the outflow side 34 to the cavity 24 through a space 35 below the dust collector 33. .

Further, the dust collecting body 33 is supported by constructing a base frame 41 on both sides of the water channel 1, and supporting bodies 4 in the vertical direction are installed on both sides on the upstream side of the base frame 41.
2 is fixed in a slightly inclined shape, and the supports 42 on both sides of the
Rotating shafts 43, 44 are provided in the upper and lower parts between them, and sprocket wheels 45, 46 are fixed to both ends of the rotating shafts 43, 44, and an endless sprocket is installed between the upper and lower sprocket wheels 45, 46 on both sides. Wrap the chain 47 around the endless chain 47 on both sides.
Both ends of a support rod 48 are rotatably spanned between a portion of the dust collector 33, and the upper end of the support portion 49 of the dust collector 33 is fixed to the support rod 48.

The endless chain 47 is driven by a support plate 51 protruding from one side of the base frame 41, a reversible deceleration motor 52 fixed on the support plate 51, and fixed to the drive shaft of the motor 52. This is done by winding an endless chain 55 between the sprocket foil 53 and the sprocket foil 54 fixed to one end of the rotating shaft 43. 56 is a cover.

In addition, a dust collection tank 6 is provided at the upper end of the base frame 41.
1 is fixed, and stoppers 62 are fixed to the lower ends of the supports 42 on both sides, and the stoppers 62 lock both sides of the dust collector 33.
Further, when the support rod 48 rises, a receiving rod 63 that follows the support rod 48 at a slight distance is provided between the endless chains 47 on both sides. The support portion 49 of the holder is locked.

Next, the dust collection effect will be explained.

Dirt in the water at the inflow side 23 of the waterway moves along the dust stopper 2, which has almost the same directionality as the water flow, and is captured by the dust collector 33, preventing it from flowing out to the outflow side 34 of the waterway. blocked.

On the other hand, the water in the inflow side 23 flows out to the outflow side 34 through the locking body 2 and the dust collector 33. Even if the dust collecting body 22 becomes clogged due to the progress of the dust trapping action by the dust collecting body 33, the inflow side portion 23
The water passes through the garbage retaining body 2 and flows out to the outflow side portion 34 through the cavity portion 24, and this garbage retaining body 2 is less likely to become clogged due to its directionality.

In particular, since the V-shaped groove 6 is formed on the upper surface of each locking rod 3a, 3b of this garbage locking body 2, even if paper or other garbage gets entangled with the upper surface of these locking rods 3a, 3b, the garbage can be removed. The water enters the V-shaped groove 6, turns inside, and is pushed upward by the rising water flow, and is swept up from the locking rods 3a and 3b to the dust collector 33, so that the locking rods Clogging in the stopper 2 can be effectively prevented.

Also, among the garbage, long and thin rod-shaped garbage such as tree branches may enter the gap 4 between the locking rods 3a and 3b, but each of the locking rods 3a, 3b
There is a gradual difference in level between the locking rods 3a and 3b, and the gap 4 between the locking rods 3a and 3b tends to widen gradually. The fitting with the gap 4 is loosened, the dust is removed from the gap 4, moves smoothly along the locking rods 3a and 3b, and is captured by the dust collector 33. Note that stick-shaped debris such as tree branches is lighter than water, so it does not completely go under the locking body 2 through the gap 4 between the locking rods 3a and 3b. Furthermore, the rod-shaped waste that is completely fitted into the V-shaped grooves 6 of the locking rods 3a, 3b moves smoothly along the V-shaped grooves 6.

Next, the dust removal function will be explained.

If dust accumulates in the dust collector 33, the motor 52
The dust collector 33 is driven by the endless chains 4 on both sides.
7 to raise it from the water. This dust collector 3
3 is supported by a receiving rod 63 after being removed from the stopper 62, and at the upper end of the support body 42, the support part 49 of the dust collector 33 enters between the sprocket foils 45 on both sides, and the support part 49 The tip of the dust collector 33 is pulled down by the support rod 48, and the side of the dust collector 33 is pushed up by the receiving rod 63, and the dust collector 33 efficiently makes a small turn above the opening edge of the dust container 61 and stands upright. Dust collection tank 61 collects internal dust.
release within. When this dust discharge is finished, the motor 52 is reversed to return the dust collector 33 to the water. Note that driving and stopping of the motor 52 may be performed using only a manual switch, or a limit switch or the like may be used. Further, the dust in the dust collecting tank 61 is taken out to the outside by opening a part of the opening/closing plate 71 of the dust collecting tank 61.

[Effect of idea]

According to the present invention, the upstream ends of all the garbage locking rods are arranged at the same height, and the adjacent downstream ends are arranged alternately in the upper and lower stages, so that there is a space between each of the locking rods. As you go from the upstream end to the downstream end, there is a gradual difference in level, and the gaps between each locking rod tend to widen, albeit slightly, so tree branches, etc. that get into the gaps between the locking rods, etc. As the rod-shaped debris is pushed toward the downstream end, the fit with the gap becomes looser, thereby preventing clogging in which the rod-shaped debris is stuck in the gap between the locking rods and becomes stuck in that position.
