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 catching and removing dust floating in a water channel such as a sewer.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 7, an endless chain 41 is circulated upstream of a lattice 40, and a rake 42 is rotatably connected to the endless chain 41 as shown in FIG. Is engaged with the grid 40. The garbage trapped in the lattice 40 is scooped up by a rake 42, and when the dust rises to a predetermined position, the rake 42
The dust put on the top was scraped off by the wiper 43, and the dust was discharged to the belt conveyor 45 via the chute 44 and conveyed to the subsequent process.

[0003]

However, the dust remover and the dust remover described above have the following problems.
That is, dust is conveyed by a belt conveyor, but the belt conveyor cannot completely prevent deodorization, and the slurry attached to the dust is scattered to contaminate the surroundings. An object of the present invention is to solve the above-mentioned problems and to provide a dust remover and a dust remover that are less likely to fail and that are hygienic with respect to the surrounding environment.

[0004]

SUMMARY OF THE INVENTION According to the present invention, an endless chain circulated up and down by a pair of left and right upper driving sprockets is wound by bringing a rising side close to an upstream side surface of a lattice provided across a water channel. A rake is rotatably supported on the endless chain in a plane orthogonal to the plane of the lattice, and guide rollers are rotatably arranged before and after in the traveling direction of the rake, and a trajectory of the chain Engage the guide rollers and the guide rollers arranged along the to maintain the attitude of the rake to circulate, thereby scooping the trash caught on the grid while the rake circulates,

[0005]

An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of an embodiment of the present invention. A plurality of dust removers 2 are arranged in parallel in a water channel 1, and these are connected by a running water trough 5. Then, the crusher 3 is disposed near the downstream end of the flowing water trough 5, and the jet pump 4 is further disposed downstream thereof. The jet pump 4 is described in Japanese Patent Application No. 2-146588 filed earlier by the present applicant. That is, a high-pressure water jet is injected from the outer peripheral side of the transport pipe, and the water and the mixture in the transport pipe are sucked and pumped by the driving force. Since the transport pipe of the jet pump 4 has an inner diameter of about 100 mm, it may not be possible to suck the dust depending on the size of the dust caught by the dust remover 2. It is arranged. Therefore, if the dust trapped by the dust remover 2 is always smaller than the inner diameter of the transport pipe of the jet pump 4, the crusher 3 is not necessary.

Next, FIG. 2 is a sectional view of the dust remover of the present invention, and FIG. 3 is a sectional view of a main part thereof. Grid 21 in waterway 1
Are set up substantially vertically, and the guide rail 2 is
2 is set up in parallel with the lattice 21. The guide rail 22 has a U-shape including a straight portion 221 and a semicircular portion 222. A head casing 23 is provided above the guide rail 22, and the head casing 23 is fixed on a slab that covers the water channel 1. A driving sprocket 24 is rotatably disposed in the head casing 23, and the driving sprocket 24 is separately driven by a driving device (not shown). A rim 24-1 protrudes from the inner facing surface of the drive sprocket 24.
In the head casing 23, a guide rail 25 is provided on the outer peripheral side of the drive sprocket 24. The guide rail 25 is the first
, A second recess 252, and a third recess 253 are provided. Since the drive sprocket 24 is vertically movable, the guide rail 25 is also vertically movable at the same time. An endless chain 27 in which a rake 26 is swingably mounted on the driving sprocket 24 and the guide rail 22 is rotatably extended. Drive sprocket 2
A running trough 5 is provided below the running trough 4 and extends through the head casing 23 on both sides thereof.

Further, in the head casing 23, three rows of water injection nozzles 28 are provided above the driving sprocket 24, and the injection water from each of the water injection nozzles 28 falls into the flowing water trough 5. A wiper 29 is pivotally supported on the lattice 21 side at the upper part in the head casing 23, and a movable chute 30 is pivotally supported on the lattice 21 side at the upper part of the running water trough 5. 4 and 5 show a combination of the endless chain 27 and the rake 26. FIG. A support shaft 272 is protruded from the endless chain 27 at an intermediate position between the rollers 271 and 271 at a predetermined pitch, and the swing plate 261 is swingably supported on the support shaft 272. The support shaft 2 is provided behind the swing plate 261 in the traveling direction.
62, a support plate 264 is rotatably supported on the support shaft 262, and a roller 26 is mounted on the opposite side of the support shaft 262.
3 is rotatably mounted. Guide rollers 265 and 266 are rotatably mounted on the front and rear of the support plate 264 in the traveling direction, and a rake plate 267 is provided on the rear side of the support plate 264 in the traveling direction.
And a plurality of rake claws 268 are erected on the rake plate 267. Then, the endless chain 27 having the rake 26 attached thereto is wound around the drive sprocket 24, and the guide rollers 265 and 266 of the rake 26 are engaged with the guide rails 22 and 25. While the chain 27 is bent by the driving sprocket 24, the guide roller 263 rolls on the rim 24-1 protruding from the driving sprocket 24, and
It regulates 6 unnecessary movements.

Next, the operation of the above configuration will be described. The dust caught by the grid 21 is lifted up by the rake claw 268 of the rake 26 which is engaged with the grid 21 and rises.
The guide roller 265 on the front side of the rake 26 is the guide rail 2
Until the first concave portion 251 of FIG. 5, the rake claw 268 is outside the elliptical locus formed by the endless chain 27,
And facing outward. Here, the upper surface of the rake claw 268 comes into contact with the wiper 29, and the mutual position between the rake claw 268 and the wiper 29 is shifted as the rake claw 268 advances, so that the dust on the upper surface of the rake claw 268 is scraped off. The dust scraped off in the meantime falls onto the movable chute 30, but the movable chute 30 is pushed upward by the rake 26, and the dust on that time is washed into the running water trough 5 by the jet water. It is.

When the rake 26 further moves upward, the guide roller 265 on the front side thereof enters the first recess 251 and is supported by the support shaft 272 and the swinging plate 261 which simultaneously advance with the endless chain 27 while temporarily stopped. Support plate 26
4 is reversed, so that the rear guide roller 266 enters inside the trajectory of the endless chain 27 and at the same time leads. At this time, the rake claw 268 is
Is inside the elliptical trajectory formed and faces inward. Dust left on the rake claw 268 by the jet water from the water jet nozzle 28 during that time is washed off into the running water trough 5. When the endless chain 27 further advances, the guide roller 266 on the rear side enters the second concave portion, and the spindle 2 which simultaneously advances with the endless chain 27 during a temporary stop.
The support plate 264 is again inverted by the 72 and the swinging plate 261, so that the front guide roller 265 precedes. At that time, the rake claw 268 is again facing outward, so that it does not hinder engagement with the next lattice 21.
