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 capturing and removing dust particles floating in waterways such as sewers.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 6, a dust remover circulates an endless chain 41 on the upstream side of a lattice 40, and a rake 42 is rotatably attached to the endless chain 41 so as to move upward. The rakes 42 of the above to the lattice 40. The dust trapped by the grid 40 is scraped up by the rake 42, and when it reaches a predetermined position, the rake 42
The dust 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 above dust remover and dust remover have the following problems.
That is, the dust is conveyed by the belt conveyor, but the belt conveyor cannot completely deodorize, and the slurry attached to the dust scatters and stains the surroundings. It is an object of the present invention to solve the above problems and provide a dust remover and a dust remover which have few failures and are hygienic with respect to the surrounding environment.

[0004]

According to the present invention, an endless chain that is vertically circulated by a pair of left and right upper drive sprockets is wound with an ascending side close to the upstream side surface of a lattice provided across a water channel. The rake is rotatably supported on the endless chain in a plane orthogonal to the plane of the lattice, and guide rollers are rotatably arranged in the front and rear of the rake traveling direction. By engaging the guide roller and the guide roller arranged along, to maintain the posture of the rake to circulate, and thus to scoop up the dust trapped in the lattice while the rake circulates,
A dust remover for discharging, wherein a guide rail is provided on the outer peripheral side of the upper drive sprocket so as to surround it, and a first recess is provided on the guide rail on the rising side of the rake with respect to the axis of the upper sprocket. , A second recess is provided on the descending side, and the rake pawl is facing outward on the rake rising side, the rake is reversed at the first recess, and the rake pawl is facing inward.
It is characterized in that the rake is re-inverted in the concave portion of the rake so that the rake claw is directed outward again.Furthermore, a water injection nozzle is provided above the upper drive sprocket and below the upper drive sprocket. A running water trough is provided, and the dust scraped up is discharged into the running water trough.Furthermore, a plurality of these dust removers are arranged in parallel, and these dust removers are installed in the running water trough. Connect with
A jet pump is placed at the downstream end of the running water trough, and the jet pump is used to convey water and dust to the next process.Furthermore, a crusher is placed at the downstream end of the running water trough. It is characterized in that a jet pump is arranged on the downstream side, and the jet pump conveys water and dust to the next step.

[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 the water channel 1, and they are connected by a running water trough 5. Then, the crusher 3 is arranged near the downstream end of the running water trough 5, and the jet pump 4 is arranged further downstream thereof. The jet pump 4 is described in Japanese Patent Application No. 2-146588 previously filed by the present applicant. That is, a high-pressure water jet is injected from the outer peripheral side of the transfer pipe, and the driving force sucks in the water and the mixture in the transfer pipe and pressure-feeds them. Since the conveying pipe of the jet pump 4 has an inner diameter of about 100 mm, it may not be able to suck the dust depending on the size of the dust trapped by the dust remover 2, so the crusher 3 may be placed in front of the jet pump 4. It is arranged. Therefore, if the dust captured 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 the main part thereof. Grid 21 in waterway 1
Is installed substantially vertically, and the guide rail 2 is provided on the upstream side of the grid 21.
2 is erected parallel to the grid 21. The guide rail 22 has a U-shape including a straight portion 221 and a semicircular portion 222. A head casing 23 is arranged above the guide rail 22, and the head casing 23 is fixed on a slab covering the water channel 1. A drive sprocket 24 is rotatably disposed in the head casing 23, and the drive sprocket 24 is driven by a separate drive device (not shown). Head casing 23
Inside the guide sprocket 24, the guide rail 2
5 is provided. The guide rail 25 includes the first recess 251 and the second recess 251.
The recess 252 and the third recess 253 are provided respectively. 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 attached to the drive sprocket 24 and the guide rail 22 described above, is rotatably provided. A running water trough 5 is provided below the drive sprocket 24, and the running water trough 5 is used for the head casing 23.
And extends to both sides thereof.

Further, three rows of water jet nozzles 28 are provided above the drive sprocket 24 in the head casing 23 so that the jet water from each water jet nozzle 28 falls into the running water trough 5. A wiper 29 is swingably supported on the lattice 21 side in the upper part of the head casing 23, and a movable chute 30 is swingably supported on the lattice 21 side on the running water trough 5. 4 and 5 show a combination of the endless chain 27 and the rake 26. A support shaft 272 is projectingly provided at an intermediate position between the F rollers 271, 271 of the endless chain 27 at a predetermined pitch, and a support plate 261 of the rake 26 is rotatably supported on the support shaft 272. Guide rollers 262 and 263 are rotatably supported around the support plate 261 in the advancing direction, and a rake plate 264 is extended behind the support plate 261 in the advancing direction. A plurality of rake claws 265 are erected on the rake plate 264. To do. Then, the endless chain 27 having the rake 26 attached thereto is wound around the drive sprocket 24, and the rake 2 is attached to the guide rails 22 and 25.
6 guide rollers 262 and 263 are engaged.

Next, the operation of the above configuration will be described. The dust trapped by the grid 21 is scooped up by the rake claws 266 of the rake 26 which is engaged with the grid 21 and rises.
The guide roller 262 on the front side of the rake 26 is the guide rail 2
The rake pawl 266 is outside the elliptical locus formed by the endless chain 27 until it reaches the first concave portion 251 of No. 5,
And facing outwards. Here, the upper surface of the rake claw 266 comes into contact with the wiper 29, the mutual position of the rake claw 266 and the wiper 29 is displaced, and the dust on the upper surface of the rake claw 266 is scraped off. The dust scraped off in the meantime falls on the movable chute 30, but the movable chute 30 is pushed upward by the rake 26, and the dust on the movable chute 30 is washed off by the jet water into the running water trough 5. Be done.

When the rake 26 further moves upward, the guide roller 262 on the front side of the rake 26 enters the first concave portion 251, and the support plate 261 is inverted by the support shaft 272 that moves simultaneously with the endless chain 27 while temporarily stopped. As a result, the rear guide roller 263 comes into the inside of the locus of the endless chain 27 and at the same time, moves forward. At this time, the rake claw 266 is inside the elliptical locus formed by the endless chain 27 and faces the inside. During that time, the dust left on the rake claw 266 by the water jet from the water jet nozzle 28 is washed off into the running water trough 5. When the endless chain 27 further advances, the rear guide roller 2
The support plate 261 is re-inverted by the support shaft 272 that moves forward with the endless chain 27 while 63 enters the second concave portion and is temporarily stopped, and the front guide roller 26
2 comes first. At that time, the rake claw 266 is directed outward again so that the engagement with the next lattice 21 is not hindered.
