DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a waste transfer facility for transferring waste generated on land to barges on water. It relates to a waste transfer facility that can be prevented.

[Prior Art] A waste transshipment facility constructed as a base for carrying waste generated on land to an offshore landfill site, as shown in FIG. 8 and FIG. Migration deck 2
The waste input stage 3 is projected above the water surface WL via the, the waste input port 4 is provided on the input stage 3, and the waste input position is switched between the land side position 4a and the offshore position 4b. A movable floor 5 is provided movably, and a dust collecting hood 6 and an air curtain are provided on the lower side of the loading stage 3 so as to face the loading port 4 in the moving direction of the movable floor 5. A fixed suction hood 13 consisting of a hood 12,
An air chamber 16 having an air blowing nozzle 15 for blowing air toward the air curtain hood 12 to form an air curtain 14 on the waste input path 4 ′ on the land side is further provided. 5 is connected to the dust collecting hood 6 when it is switched to the offshore position 4b, and a dust collecting relay hood 7 as a movable suction hood is suspended and supported. After the loading barges 8 have been loaded and moored, the trucks 10 loaded with the wastes 9 are loaded onto the loading stage 3 and tilted to the loading platform 11 so that the wastes are placed on the barges 8 above the water from the loading port 4. 9 is thrown.

In the waste transfer facility, the movable floor 5 is moved to appropriately switch the input position of the waste 9 to the land side position 4b, so that the load of the waste 9 on the barge 8 can be balanced. The dust floating around the periphery 4 can be sucked into the dust collecting hood 6 directly or via the dust collecting relay hood 7, and the dust can be prevented from being diffused by the action of the air curtain 14. . In order to prevent the waste 9 from scattering on the water surface, a diffusion prevention sheet 25 adapted to follow the fluctuation of the barge 8 due to the water level and the loading amount of the waste 9 covers the entire circumference of the barge 8. It is suspended under the floor of the loading stage 3 so as to surround it.

[Problems to be solved by the invention] However, in the case of the above-mentioned waste transshipment facility, the waste 9
Since the movable floor 5 is provided to switch the charging position of the dust, the relay hood 7 for dust collection as a movable suction hood that moves integrally with the movable floor 5 corresponding to the dust collection hood 6 of the fixed suction hood 13. Although necessary, the relay hood for dust collection 7
Regardless of whether the movable floor 5 is at the land side position 4a or the offshore position 4b, one of the open ends is exposed to the waste input passage 4 '. Is located at the land side position 4a, the open ends of the dust collecting hoods 6 of the fixed suction hood 13 and the air curtain hood 12 are also disposed in the waste input passage 4 '.
These hoods 7, 6, 12
There is a problem that the waste 9 accumulates on the lower bottom surface of the opening end portion of the device. Further, the air curtain 14 is formed in the waste introduction path 4 'in order to prevent dust from being scattered when the waste is introduced. However, the distance between the air blowing nozzle 15 and the air curtain hood 12 depends on the entrance port. Because it is long according to the width of 4,
There is a problem that the opening height of the air curtain hood 12 increases with the spread angle of the air curtain 14, and the air volume for forming the air curtain 14 increases. Furthermore,
Since the dust-collecting relay hood 7 has a structure in which the dust-collecting hood 6 is simply pressed against the dust-collecting hood 6, air leaks are likely to occur in the joint portion, causing a reduction in the dust-collecting effect. .

Therefore, the present invention enables the opening height of the air curtain hood to be reduced and the air curtain air volume to be reduced, and prevents waste from accumulating on the fixed suction hood and the movable suction hood. It is another object of the present invention to prevent the air leak at the joint between the fixed suction hood and the movable suction hood, thereby improving the dust collecting effect.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a waste input port of a waste input stage with a movable floor for switching the input position of the waste, A fixed suction hood consisting of a dust collecting hood and an air curtain hood, and air is blown out toward the air curtain hood so that waste is injected into the lower surface so that the inlet is opposed to the movable floor in the moving direction of the movable floor. In a waste transshipment facility provided with an air blowing nozzle for forming an air curtain on a road and suspending and supporting a dust collecting relay hood that can be connected to the dust collecting hood on the movable floor, A relay hood for an air curtain, which forms a movable suction hood together with the relay hood for dust collection, can be attached to the air curtain hood below the relay hood for dust collection. And a relay nozzle for blowing air toward the air curtain hood is connected to the movable suction hood so as to be connectable to the air blowing nozzle.

In addition, the dirt is obliquely downwardly directed to the bottom of the bottom of the open end of the dust collection hood and air curtain hood of the fixed suction hood, and the bottom of the bottom of both the openings of the relay hood for dust collection and the air hood of the movable suction hood. It is preferable that each plate is provided.

Further, a configuration may be adopted in which a seal plate for preventing air leak is attached to a portion where the fixed suction hood is connected to the movable suction hood.

[Operation] When the movable suction hood is combined with the fixed suction hood by moving the movable floor, air blown from the air blow nozzle forms an air curtain between the air blow nozzle and the air curtain relay hood. Therefore, dust is sucked into the air curtain hood via the air curtain relay hood.On the other hand, when the movable suction hood is separated from the fixed suction hood and the relay nozzle is connected to the air blowing nozzle, the air of the air blowing nozzle is reduced. Is blown out from the relay nozzle to form an air curtain between the relay nozzle and the air curtain hood, so that dust is directly sucked into the air curtain hood. Further, when the movable suction hood is combined with the fixed suction hood, the fitting portion is sealed by the seal plate, so that air leaks can be eliminated and a high dust collection effect can be obtained. Furthermore, since the lower bottom surface of the open end of the fixed suction hood and the lower bottom surface of both the open ends of the movable suction hood are each provided with a diagonally downwardly directed earthing plate, the waste is thrown away at the time of waste input work. Objects do not accumulate on the bottom surface below the open end of each hood.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 6 show an embodiment of the present invention.
In the same configuration as the waste transfer facility shown in FIGS. 8 and 9, the movable floor 5 is connected to the air curtain hood 12 when the movable floor 5 is switched to the offshore position 4b below the dust collecting relay hood 7. An air curtain relay hood 18 for distributing the air 14a blown out from the air blowing nozzle 15 toward the air curtain hood 12 is formed as a movable suction hood 19 integrated with the dust collecting relay hood 7. The movable suction hood 19 is connected to the air blowing nozzle 15 when the movable floor 5 is switched to the land side position 4a, so that the air 14a is blown toward the air curtain hood 12 so that the air is blown out. A relay nozzle 17 for forming a curtain 14 is assembled, and further, on the lower bottom surface of each open end of the fixed suction hood 13 and the movable suction hood 19, that is, the dust collection hood 6 and the air curtain hood. Bottom of the opening end of the door 12, the relay hood 7 for dust collection, and the relay hood for the air curtain
Discharge plates 20 are respectively provided diagonally downward on the lower bottom surface of the opening end portions on both sides of 18. Also, as shown in FIGS. 4 and 5, a leaf spring is formed by bending the fixed suction hood 13 into a concave shape on the outer peripheral edge of a portion where the fixed suction hood 13 is connected to the movable suction hood 19.
21 is mounted as a seal plate having a divided structure via a holding plate 24, so that air leak from an engagement portion between the fixed suction hood 13 and the movable suction hood 19 can be prevented.
As shown in FIG. 6, a relay nozzle of the air blowing nozzle 15
The liner 22 is attached as a gap adjusting plate to the connection surface with the air nozzle 17 so that air leak from the connection between the air blowing nozzle 15 and the relay nozzle 17 can be prevented. Reference numeral 23 denotes a traveling rail for the movable floor 5.

In the case where the waste 9 is input using the land side position 4a of the input port 4, as shown in FIGS. 1 and 2, the movable floor 5 is moved to the offshore position 4b by moving the movable floor 5 to the offshore position 4b. The suction hood 19 is attached to the fixed suction hood 13, and the air 14 a is blown out from the air blowing nozzle 15 toward the air curtain relay hood 18 of the movable suction hood 19, and the land side position 4 of the inlet 4 is set.
It is assumed that the air curtain 14 is formed in the charging path 4 ′ located below “a”.

In this state, when the waste 9 is loaded from the truck 10 carried on the loading stage 3 to the barge 8 moored on the water surface WL below the loading stage 3, the waste 9 is transferred to the loading port 4.
Is loaded on the barge 8 through the land side position 4a. Dust generated during the charging operation is sucked into the dust collecting hood 6 of the fixed suction hood 13 through the dust collecting relay hood 7 of the movable suction hood 19, and thus, is prevented from scattering around. The waste 9 falling toward the barge 8 passes through the air curtain 14 formed in the charging path 4 '. At this time, the dust not sucked into the dust collecting hood 6 is removed by air. The curtain 14 forces the air curtain relay hood 18
Since it is sent into the inside and sucked into the air curtain hood 12, scattering of dust can be reliably prevented. Further, at this time, the movable suction hood 19 of the fixed suction hood 13
Since a leaf spring 21 is attached as a seal plate to the periphery of the connecting portion with respect to the movable hood 13, the movable suction hood 19 can be connected to the fixed hood 13 without any gap by simply pressing the hood 13 therebetween. , 19 can be eliminated, and the dust collecting effect can be enhanced, whereby the exhaust fan for dust collection can be minimized in capacity. The above leaf spring
Since 21 has a split structure, only the damaged portion can be easily replaced.

On the other hand, when the waste 9 is charged using the offshore position 4b of the charging port 4, the movable floor 5 is switched to the land side position 4a as shown in FIG. Release the connection of the movable suction hood 19, and replace the relay nozzle 17 attached to the movable suction hood 19 with the air blowing nozzle.
Connect to 15. This allows air blowing nozzle
Air 14a blown out from 15 passes through relay nozzle 17,
It is blown out from the tip of the relay nozzle 17 toward the air curtain hood 12, and the charging path 4 'below the offshore position 4b of the charging port 4.
Then, the air curtain 14 is formed. At this time, since the liner 22 is provided as a gap adjusting plate on the connection surface of the air blowing nozzle 15 to the relay nozzle 17, the relay nozzle 17 can be securely connected without a gap, and air leak from the connection portion is reduced. Can be prevented. Therefore, when the work of charging the waste 9 is performed using the offshore position 4b of the input port 4, the dust generated at this time is directly sucked into the dust collecting hood 6 and the air curtain hood 12, Scattering can be prevented.

In the above, when the waste 9 is charged using the land side position 4a of the charging port 4, the movable suction hood is used.
19 dust collecting relay hood 7 and air curtain relay hood
Each of the land-side opening ends 18 is exposed at the waste input passage 4 '. On the other hand, when the push side position 4b of the input port 4 is used, the dust collecting relay hood 7 and the air curtain are used. Each open end of the relay hood 8 and each open end of the dust collection hood 6 and the air curtain hood 18 of the fixed suction hood are exposed at the input path.
At the lower bottom of each of the open ends of the openings 6 and 12, there are provided diagonally downwardly facing earth discharging plates 20, respectively. Therefore, there is no possibility that the waste 9 accumulates at these portions and is blocked.

Further, in the above, the relay nozzle 17 that is connected to the air blowing nozzle 15 when the movable floor 5 is switched to the land side position 4a is assembled to the movable suction hood 19,
There is an advantage that the opening height of the air curtain hood 12 of the fixed suction hood 13 can be reduced. That is, as shown in FIG. 7, the nozzle diameter of the relay nozzle 17 is d, and the air curtain hood is
When the opening height of the opening 12 is D and the distance between the tip of the relay nozzle 17 and the opening end of the air curtain hood 12 when connected to the air blowing nozzle 15 is L, the height D is At this time, the air volume Q of the air curtain 14 is Can be obtained as Therefore, when the relay nozzle 17 is provided, L can be shortened, and as a result, D can be reduced, and accordingly, Q can be reduced.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the scope of the present invention.
