DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust removing device for a water channel in which dust flowing in a water channel or a drain channel is accommodated in the same channel.

[0002]

2. Description of the Related Art Heretofore, by removing dust that flows into a water channel or a drain channel, a function of flowing water has been maintained and an environment has been sanitized. The device for this is shown in FIG.
As shown in the figure, a screen 2 is provided across the water channel 1,
A rake 3 is installed movably upward along the screen 2, a driving device 4 for the rake 3 and a storage bin (not shown) are installed on the ground, and along the top of the screen 2 to put dust into the storage bin. In some cases, a belt conveyor 5 is provided. When the driving device 4 is operated, the rake 3 moves above the water surface on the screen 2 and scrapes the dust hanged on the front surface on the upstream side of the screen 2 to the ground, and the empty rake 3 is moved to the lower end of the underwater screen 2. Moved, continuously scraping garbage. The scraped garbage is stored in the storage bin via the belt conveyor 5.

Since the screen 2 is provided over the entire cross section of the water channel, the above-described device must be constantly operated so that the screen 2 is not clogged with dust. For this reason, there arises a problem of introduction of electric power machines and unmanned operation. Further, there is a problem that odor is generated because the dust is exposed to the atmosphere and stored.

[0004] As shown in FIGS. 5 and 6, an apparatus taking the above problem into consideration has a side channel 6 provided alongside a water channel 1.
A shield plate 8 for guiding flowing water to an inflow port 7 is attached at an angle obliquely crossing the water channel 1 and hanging down from the upper layer of flowing water. In the side channel 6, a cage 9 having a number of holes, which is approximately the same as the width, is installed in water. Further, a gate 10 is provided downstream of the position of the inlet 7, and an outlet 11 of the side passage 6 is formed downstream of the gate 10.

[0005] This device excludes deep portions with very little garbage from the object of dust removal and excludes only the vicinity of the water surface from dust removal. The upstream water level is kept constant by using a gate 10, and the shielding plate 8 is moved approximately from the water surface. It is installed vertically to a depth of 30cm.
Most of the refuse flowing down the water channel 1 is floating or is located in the upper part of the flowing water, and is guided to the side channel opening 7 by the shielding plate 8. In the side channel 6, garbage flows into the cage 9 together with a part of the running water, and the filtered running water flows into the gate 10.
And the refuse is stored in the cage 9. Thereafter, the cage 9 is pulled up to remove dust.

[0006]

However, since the shielding plate 8 is fixed to the water channel 1, it is difficult to guide dust when the upstream water level fluctuates. Therefore, the gate 10 is required to keep the upstream water level constant. However, there is a problem that equipment costs increase. In addition, a road for carrying the collected dust must be secured, but a site for providing the side flow path 6 is required. Also, functionally, when the water flow increases and the water level difference between the upstream and downstream of the gate 10 decreases,
Since the amount of water passing through the side channel 6 is reduced, there is a problem that dust cannot be guided to the cage 9.

An object of the present invention is to provide a dust removing device for a water channel which is not affected by the upstream water level and requires no additional installation space.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a method in which a pedestal is supported by a height adjusting device in flowing water of a waterway, and the upper part of the pedestal is provided at the upper part of the waterway over the entire width of the waterway. Further, a side plate is vertically arranged so as to obliquely cross the water channel, and a chute having a narrowed downstream port is fixed thereto, and a cage having a perforated plate and having an opening on a side surface is provided on the downstream upper portion of the gantry. The opening is aligned with the downstream port of the chute and placed.

A screen is detachably provided at the downstream side of the chute.

[0010]

With the above construction, the height of the gantry located in the water can be adjusted, and the chute and the cage can be installed on the upper layer of the running water. In addition, the flowing water passes through the perforated plate of the cage and also flows from below the gantry, so that the flowing water is not blocked.

Most of the garbage is so-called floating garbage,
Collected by shoots and housed in cages. Even if dust is stored in the cage, the running water flows downstream, so that the cage can be kept underwater. Also, when removing garbage, raise the cage.

The screen disposed at the downstream port of the chute is installed in running water when the cage is pulled up to prevent dust from flowing out downstream.

[0013]

Embodiments of the present invention will be described below with reference to the accompanying drawings. First, an outline of the dust removing device will be described. As shown in FIGS. 1 to 3, a pair of main girders 12 are traversed at appropriate intervals on the upstream side and the downstream side of the water channel 1, and are fixed to the upper end of the side wall. A height adjusting device 14 having two racks 13 vertically arranged on a pair of main girders 12 is attached to each of the four racks 13.
Is fixed to the gantry 15. Then, the cage 16 is placed on the upper portion on the downstream side of the gantry 15. In addition, a chute 17 is fixed to the upper part on the upstream side of the gantry 15,
A screen 18 is provided between the screen 17.

Bearings 19 are fixed to both ends of the main girder 12, and a connecting shaft 20 of the height adjusting device 14 is rotatably supported. The rack 13 penetrating the main girder 12 is engaged with a pinion 21 fixed to the connecting shaft 20 at the upper part of the main girder 12. On one side of the two connecting shafts 20 arranged above the main girder 12, an operating shaft 22 is disposed orthogonally to the connecting shaft 20 with both ends supported by bearings 19, and a worm attached to the connecting shaft 20. The wheel 23 and the worm gear 24 attached to the operation shaft 22 are meshed and linked. A handle 25 is fixed to an end of the operation shaft 22. The rack 13 is covered with a casing (not shown) provided on the main girder 12 to protect tooth surfaces and guide sliding.

The gantry 15 is composed of a pair of vertical beams arranged in the upstream and downstream directions.
Two connecting girders on which the cage 16 is placed, at the lower part on the downstream side of 26
Attach 27 at intervals and attach 3
The cross beams 28 of the books are fixed at intervals, and the cross beams 28 fixed to the upstream end have a length approximately equal to the width of the water channel. The interval between the vertical beams 26 of the gantry 15 is wider than the width of the cage 16, and a stopper 29 for supporting the rear side surface of the cage 16 is fixed to the downstream end of the vertical beams 26. A column 31 for supporting the switch 30 is fixed to one side of the middle horizontal girder 28, and the above-described rack 13 is fixed to an intermediate portion and a downstream end of the vertical girder 26, respectively.

The chute 17 comprises a side plate 32 and a bottom plate 33, and is fixed to the upstream end of the gantry 15 and to the middle cross beam 28.
A waterproof rubber 34 is fixed to the upstream end of the side plate 32 so as to be in close contact with the side wall of the water channel 1. Further, the side plate 32 extends to the downstream side toward the center of the water channel, and narrows the width of the downstream side port 35 of the chute 17.

From the downstream port 35 of the chute 17, there is an induction channel 36.
Are connected in parallel, the width of the guide channel 36 is smaller than the width of the cage 16, and the bottom of the guide channel 36 is
It is higher than the bottom of the cage 16 by the thickness of 28.

The cage 16 is installed with an opening 16a on the side face arranged on the upstream side. The three side surfaces and the bottom surface are formed by a perforated plate 37 having a large number of holes, and the perforated plate 37 is formed by a large mesh and a strong outer plate and a small mesh inner plate. In addition, handles 39 for lifting with a crane 38 are provided at the four upper corners of the cage 16, and it is only necessary to secure a carry-out path by using a truck equipped with the crane 38. Since the crane 38 has a small installation space, it may be arranged at the nearest position.

The screen 18 is formed by fixing a large number of screen bars 41 to a rectangular frame 40.
Are located in A screen shaft 42 traversing the downstream port 35 is rotatably supported by a bearing 19 fixed to the upper end of the side wall of the guide channel 36. The screen 18 has its upper end connected to the screen shaft.
Hanged on 42.

The screen shaft 42 is connected to the switch 30 via a pin 43.
Of the open / close shaft 44, and the other end of the open / close shaft 44
Is supported by a bearing 19 fixed to a support 31 of the
A worm wheel 45 is fixed at 44. In addition, prop 31
, A vertical shaft 46 is vertically supported, and a worm gear 47 fixed to the vertical shaft 46 and a worm wheel 45 mesh with each other. A handle 48 is fixed to the upper end of the vertical shaft 46, and The switchgear 30 can be operated from above the side wall. The handle operation is to rotate the screen 18 from the hanging position to the downstream and upward.

Next, the operation will be described. There are two types of garbage: those that flow down while being swept down the bottom of the water channel 1 and those that flow while floating. Most of the garbage floats overwhelmingly. Submerged in water at 14, the cage 16 is placed on the connecting girder 27, and adjusted by the height adjusting device 14 so that the cage 16 is arranged on the upper layer of the running water.

In this case, the width of the cage 16 is larger than the width of the guide channel 36, and there is no problem even if the mounting position is shifted. Also, if the current is strong, the cage 16 moves downstream after being put on, but the rear side is supported by the stopper 29,
In addition, since the stringers 26 hold the side surfaces of the cage 16, it is possible to prevent the girder from falling off the gantry 15.

The water channel 1 is divided into a channel that flows through the cage 16 and a channel that flows below the cage 16, and the height of the gantry 15 can be appropriately adjusted according to the flow rate.
There is no hindrance to the flow of dust and running water, and the dust can be reliably guided into the cage 16. If the height of the gantry 15 is adjusted when the cage 16 is removed from the gantry 15, such as when the cage 16 is replaced, the weight can be easily adjusted without burden. Further, since the height position of the cage 16 is adjusted to the upstream water level, there is no need to use a gate unlike the related art, no side channel is required, and there is no need to expand the installation space. In addition, since a flow path that flows downstream is ensured, dust can be collected without interruption
No need to scrape from

Further, since the chute 17 is provided, the water of the entire width of the water channel is collected at the center, so that the dust rushes through the guide water channel 36. The screen 18 provided at the downstream port 35 of the chute 17 is operated by operating the handle 48 and is lifted upward in the downstream. The mechanical structure of the opening / closing device 30, that is, the self-locking by the worm gear 47,
Can always maintain a horizontal position in the air. Therefore, it does not hinder the flow of garbage.

In the cage 16 for storing dust, the outer plate can withstand the pressure and weight of the dust, and the dust can be captured by the inner plate. Further, small dust below the mesh passes through at the initial stage, but when a certain amount of dust accumulates, a phenomenon occurs in which the dust is filtered by the dust, so that small dust below the mesh is also captured. Since the rack 13 is the same as the one located on the downstream side with respect to the cage 16, dust does not get entangled with the rack 13.

Next, a case where the cage 16 is replaced will be described. First, the handle 18 is operated to drop the screen 18. By the self-lock described above, the vertical position can be maintained against the water pressure. Therefore, the dust is prevented from flowing downstream, and is stored in the upstream portion of the chute 17.
During this time, a wire is hung on the hook of the crane 38 to lift the cage 16 and put it on the truck as it is. Therefore, the carry-out processing can be performed without touching the dust.

Thereafter, the empty cage 16 is suspended and placed on the gantry 15, and the handle 18 is operated to move the screen 18 toward the downstream and upward, so that the screen 18 is accumulated at the upstream portion of the chute 17. The garbage smoothly flows down into the cage 16.
In addition, by using a dump truck equipped with a non-slip cage 16, the carrier 16 is automatically placed by placing the upstream opening of the cage 16 behind the dump truck and tilting the loading platform at the garbage disposal plant. Can be released.

On the other hand, the decay rate of the stored dust depends on the amount of oxygen in the water. In numerical terms, the amount of oxygen in the air is about 2
At 0%, in other words 200,000 ppm, the oxygen content in water at 16 ° C. is only 15 ppm. Therefore, the rate of decay is slow in water, and the odor does not drift in the air because it is in water. In addition, since the rot has not progressed even when being carried out by truck, the odor is reduced.

[0029]

Since the present invention is constructed as described above, the cage can be installed in the upper layer of flowing water regardless of the upstream water level by adjusting the height of the cage, so that the flow of the flowing water is not obstructed and the dust is removed by the chute. The garbage can be stored in a cage underwater. Therefore, a new installation space for the device is not required, the structure is simple, the device is inexpensive, the device has no power, and an environment in which no odor is generated can be provided. Also, when the cage is pulled up, the screen is operated to prevent dust from flowing out downstream, so that dust in the water channel can be surely removed.
