Description

[0001]
[Industrial applications]
The present invention relates to a dust remover that separates dust that floats or mixes in flowing water in rivers and waterways and lifts it up on land, and conveys the dust that has been separated and pulled up from that point to a collection point. The present invention relates to a device for transporting garbage of a dust removing device to be accumulated.
[0002]
[Prior art]
Conventionally, as a device for transporting garbage in dust removal equipment,
(1) Dust is fed into the belt conveyor and transported, the end point of the conveyor is set sufficiently higher than the collecting floor, and the dust that falls when the belt is inverted at the end point of the conveyor is collected at that point.
(2) The dust is thrown into the so-called chain conveyor in which a number of conveyor rods driven by a conveyor chain move and the bottom of the steel rectangular chute is transported, and the end point of the conveyor is set sufficiently higher than the accumulation floor surface to end the conveyor. The garbage that falls when the chain is turned over is collected at that point.
(3) In a dust removing device that captures dust of a small size by a wire mesh, the wire mesh is washed, a large amount of water is added to the water mixed with the dust, and the inside of the chute is caused to flow down. The garbage is discharged and collected on the collecting floor by raising and reversing the bucket.
And so on.
[0003]
[Problems to be solved by the invention]
However, in the above-mentioned conventional examples (1) and (2), the construction cost of the conveyor is expensive, and a part of the garbage that has just been separated from the water is transferred to a belt, chain, or transport rod at the end point of the conveyor. There is a case where the toner enters the reversing section with the toner adhered, and contaminates the transfer device or impairs the operation.
[0004]
Further, the above-mentioned conventional example (3) is used only for dust having a small size of about 25 mm to 50 mm which is captured by a wire net, and the dust is conveyed in a chute floating overwhelmingly in a large amount of water. Therefore, it required a pump with a very large lift compared to the garbage to be conveyed, so wood chips, branches, grass, defoliation, household waste, waste plastic, corpses of small animals, etc. like garbage flowing into the river It was large in size and was not used in the case of garbage of various configurations.
[0005]
In view of the above, the present inventors have previously disclosed in the invention of Japanese Utility Model Application No. Hei 4-75441, in a river or waterway, separated dust that has floated or mixed in running water, from the point where it was separated and pulled up to the point of accumulation. A chute in the form of a channel with a straight line and a gentle curve in a plane, and having a moderate downward gradient toward the accumulation point in the longitudinal direction is provided.At the start of the chute, water is pumped up by a pump and the chute is taken. A constant water flow is always formed at a shallow depth inside the chute.Furthermore, a porous bucket is provided at the end of the chute, and once all the water and dust flowing down the chute are received, only the water is discharged from the hole to discharge the dust. Is installed so that it can catch the dust, and the dust put near or at the start of the chute flows down the chute like a debris flow, is transported to the end of the chute, and is discharged to the accumulation point. Proposed a conveying device dust dedusting apparatus adapted to the product.
[0006]
However, also in the above-mentioned invention, at the end point of the chute, the dust is piled up at one place in the bucket having the porous structure, and it is difficult to efficiently use the entire bucket to accumulate the dust.
[0007]
That is, as shown in FIGS. 7 and 8, in a configuration in which dust is discharged from the end point of the chute 8 along the water flow direction, the dust is piled up from the bottom of the bucket 9 having a porous structure. When a long piece of wood or the like is contained, the outlet of the chute 8 is blocked, causing various adverse effects.
[0008]
Therefore, the present invention is to solve the above-mentioned drawbacks of the conventional example, and the dust is evenly dispersed in the bucket 9 having the porous structure, and the dust can be accumulated efficiently using the entire bucket. It is an object of the present invention to provide a dust transfer device for a dust removing device.
[0009]

[0013]
【Example】
Hereinafter, an embodiment of a dust transfer device of a dust removing apparatus according to the present invention will be described with reference to the drawings.
[0014]
FIGS. 1 to 4 illustrate an embodiment of a dust transfer device of a dust removing apparatus according to the present invention.
[0015]
FIG. 1 is a vertical cross-sectional view of a water channel in which a dust removing device is installed. Dust mixed in water flowing through the water channel is applied to a screen 1 in which flat steel is laid side by side at a fixed interval over the entire width of the water channel by being inclined downstream. , Cannot flow down waterways. The dust is driven by a chain car 4, pulled up along the upstream surface of the screen 1 by a rake 2 attached at several places to an endless chain 3 guided by the chain cars 5, 6 and 7, and thrown into a chute 8. Is done.
[0016]
FIG. 2 is a vertical cross-sectional view of the garbage conveying device, and the chute 8 can receive garbage drawn from any position in the width of the water channel across the water channel in which the dust removing device is installed. It is installed at a gradient of 1 / n in the direction, and water and dust can flow down. In the figure, a bucket 9 having a porous structure is supported by a support base 10 at a position below the end of the chute 8 so as to be able to receive all of the water and dust flowing down the chute 8.
[0017]
Further, since the water pumped up by the pump 18 via the strainer 16 and the pipe 17 is injected into the start end of the chute 8 by the pipe 19, a constant water flow is formed in the chute 8 at a shallow depth.
[0018]
The water flowing down the chute 8 enters the bucket 9, flows out of the drain hole, and returns to the water channel through the bucket pit 15 and the drain pipe 20.
[0019]
When a large amount of dust including large-sized ones is thrown into the chute 8 in such a state, the water flowing down the chute 8 is hindered by the dust and increases the water depth on the upstream side of the dust. When the water depth on the upstream side of the dust becomes sufficiently large, the water becomes a flow involving the dust, flows down to the end of the chute 8 at a stroke like a debris flow, and falls into the inside of the bucket 9.
[0020]
Among the water and dust falling into the bucket 9, dust remains in the bucket 9, so the bucket 9 is transported to another place to discharge the dust, so that the bucket 9 is returned to the original position and used again. can do.
[0021]
3 and 4 show details of the bucket 9 used in the present invention. The bucket 9 having a porous structure provided at the end of the chute has a vertically long water passage hole 31 formed at the upper portion to enable rapid drainage, and a small circular water hole 32 is formed roughly at the lower portion to form a gentle hole. It is designed to drain.
[0022]
The water and dust falling into the perforated bucket 9 are gently drained in the lower part of the perforated bucket 9, so that the water is stored and the debris floats above the water. Therefore, the dust is dispersed on the stored water, and the dust can be accumulated by efficiently using the entire bucket 9.
[0023]
On the other hand, when the stored water rises to the upper part in the porous structure bucket 9, the vertically long water passage holes 31 are densely formed, so that the water is quickly drained, and the dust does not overflow from the upper edge.
[0024]
FIGS. 5 and 6 show another embodiment of the dust transfer device of the dust removing device of the present invention. In this example, a discharge wall 33 inclined with respect to the water flow direction is provided at the end point of the chute 8, and a discharge port 34 is formed on the side of the chute 8 where the discharge wall 33 approaches.
[0025]
Therefore, the dust reaching the end point of the chute 8, particularly the long timber 35, hits the discharge wall 33 inclined with respect to the direction of the water flow, and is changed in direction. It is put into the bucket 9 having a porous structure in a horizontal state.
[0026]
Similarly, other refuse is discharged from the horizontally long discharge port 34 provided on the side surface of the chute 8 and is evenly introduced along the length direction of the bucket 9 having the porous structure.
[0027]
【The invention's effect】
According to the dust transfer device of the dust removing apparatus of the present invention, dust is evenly dispersed in the porous bucket, so that the entire bucket can be efficiently used to accumulate dust.
[0028]
In addition, even when long dust or the like is included in the dust, the discharge port of the chute is not blocked, and a dust removing device for a dust removing device that is free from trouble for a long period of time can be provided. became.
