Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gutter cleaning mechanism, and its purpose is to provide a gutter cleaning mechanism that can perform on-site dehydration treatment of sludge that settles in road gutter, etc.

Traditionally, dredging of national highways, prefectural roads, and other road ditches, as well as dredging of sludge accumulated in sewage pipes buried in roads, etc.
They relied on human power or sucked it in with a suction truck.

Among these suction vehicles, especially JP-A-49-11328
No. 61 (name: Mobile suction treatment device) and patent application 1982-1
3125 (Unexamined Japanese Patent Publication No. 56-111017, name: Mobile suction processing device), a suction work vehicle that uses a combination of air conveyance and internal vacuum pressure was particularly effectively used. .

However, although such suction vehicles are extremely effective in suctioning and treating sludge from roadside sewer pipes,
Although these working vehicles were effective in simply collecting and transporting the actual material to be treated (sludge truck), there were problems in the final treatment of the absorbed material.

In other words, the sludge absorbed into the work vehicle contains a lot of water, so
Disadvantages include that dumping causes environmental disturbance at the dumping site, or that the dumping site is far away, such as a coastal reclaimed land, and traffic conditions worsen, requiring many trips or high work costs. It was hot.

This invention has been made in an attempt to eliminate the above-mentioned drawbacks of the prior art.

The first purpose of this invention is to collect sludge from side ditches or sewage, separate the recovered sludge into solid and liquid at the dredging site, return the liquid content to the original side ditch or ditch, and treat the solid content. To provide a gutter cleaning mechanism capable of easily achieving a dry state with increased density.

A second object of the present invention is to provide a gutter cleaning mechanism capable of suctioning and removing sludge from inside a centrifugal dehydrator by operating a suction mechanism. The third object of this invention is to separate the sludge from the road gutter sucked into the centrifugal dewatering machine into water and solid content, and discharge the water from the filtration tank to the outside of the vehicle. To provide a gutter cleaning mechanism that discharges water from a dehydrator to a cake tank, dumps up the cake tank, and discharges the cake to the outside of the system.

A fourth object of the present invention is to provide a gutter cleaning mechanism that can use either a perforated or non-perforated vertical centrifugal separator as a centrifugal dehydrator. The fifth purpose of this invention is to
The purpose of the present invention is to provide a gutter cleaning mechanism which can be either a portable type fixed on a required frame or a tower-mounted type mounted on a vehicle. DESCRIPTION OF THE PREFERRED EMBODIMENTS A mounted gutter cleaning mechanism according to an embodiment of the present invention will be described below based on the drawings.

In the figure, 1 is a cake tank, and this cake tank 1
is horizontally laminated with the lid 2 facing backward, and has support legs 3 that are extendable and retractable.
It is attached to the frame 4 via.

When the supporting legs 3 are extended, they are dumped up and the contents of the cake tank 1 are discharged to the outside of the system.

This discharge is carried out by a belt conveyor (not shown) or mainly by a dump truck (not shown).

Reference numeral 5 denotes a centrifugal dehydrator, for example, a vertical centrifugal sedimentation machine, in which solid matter is attached to the suction port 6 of the cake tank 1 and the vertical centrifugal sedimentation machine 5 extending from the center of the vertical centrifugal sedimentation machine 5 to near the bottom. It is connected in communication with the discharge pipe 7 of.

8 is a suction pipe, and this suction pipe 8 is connected to a flexible suction pipe that sends sludge 10 into the basket 9 in the vertical centrifugal sedimentation machine 5, and the starting end of this suction pipe is connected to a road gutter (not shown). Extend it and suck up the sludge in the gutters.

11 is a rotary shaft, 12 is a scraping material that can be moved remotely, 1
4 is a water drain pipe.

This moisture drain pipe 14 is led to a filtered water tank 15, and the filtered water is discharged to the outside of the system via a pump 16.

17 is a suction mechanism such as Roots Prower, and in this embodiment, since it is a vehicle-mounted type, this suction mechanism 17 is connected to the P of the vehicle.
Although it is driven from the -T-0 axis via gears, etc., in the case of other portable types, another independent drive source may be used.

18 is a wet mist catcher, a suction mechanism 17 communicates with the first wet mist catcher 18A, and this suction mechanism 17
The second wet mist catcher 18B communicates with the second wet mist catcher 18B.

The first wet mist catcher 18A introduces conveying air from the suction port 19, then introduces the conveying air from this first wet mist catcher 18A to the suction mechanism 17, and converts the exhaust air from the suction mechanism 17 into the secondary Mist catcher 18B
The air is purified again, and the air is dissipated from the secondary mist catcher 18B to the outside of the system.

Switching valve device For example, in this embodiment, a three-way valve 20 communicates with the cake tank 1 and the vertical centrifugal settler 5, and by switching the three-way valve, either the cake tank 1 or the vertical centrifugal settler 5 is switched to the first one. Communicates with wet mist catcher.

The gutter cleaning mechanism consisting of such a mechanism first operates the three-way valve 20 to connect the first wet mist catcher 18A and the vertical centrifugal sedimenter 5, and then operates the suction mechanism 17 to connect the vertical centrifugal sedimenter 5. The sludge 10 in the side gutter is fed into the vertical centrifugal settler 5 through air suction pipe 8 from within the settler 5 .

While driving the rotary shaft 11 of the vertical centrifugal sedimentation machine 5,
When the sludge 10 is sucked in, the solid content remains in the basket 9,
Moisture is introduced into the filtered water tank 15 via the holes in the basket 9 (perforated type) or overflows the basket 9 (non-porous type) from the moisture drain pipe 14, and from the filtered water tank 15 via the pump 16. Drain the filtered water out of the system.

The solid content from which water has been removed remains in the basket 9, and when the scraping material 12 is brought close to the basket 9, the basket 9 is removed.
Solids stuck to the inner periphery are gradually scraped off to the bottom.
In this state, when the three-way valve 20 is switched to communicate the first wet mist catcher 18B and the cake tank 1, air is sucked from inside the cake tank 1 by the operation of the suction mechanism 17, and the solids inside the vertical centrifugal settler 5 are (sludge 10 from which water has been removed) is transferred into the cake tank 1 via the discharge pipe 7 and the suction port 6. When the cake tank 1 is filled with solids by repeating the above operations, the low pressure state in the cake tank 1 is released, and the lid part 2 is opened while extending the support legs 3 (phantom line in Fig. 3). The solid content will be transported out using a dump truck.

As described above, the gutter cleaning mechanism according to the present invention can separate sludge from roadside structures into solids and moisture at the treatment site, and can easily discharge the solids from the system by dumping up the cake tank. The entire cleaning mechanism can be mounted on a vehicle or be stationary and portable, providing revolutionary effects.
