Hereinafter, with reference to the accompanying drawings, Figures 3 to 8 with respect to the drainage device for drainage installed rake cleaning device according to the present invention.

In the present invention, as shown in Figures 3 and 4, the rake cleaning device 27 is further installed in the known waste collection apparatus 1.

The known waste collection apparatus 1 is installed in a waterway 100 such as a sewage treatment plant, a drainage pumping station, an intake station, and other industrial sewage treatment plants, and a concrete structure 101 covering the waterway is installed on the upper part of the waterway. In addition, between the concrete structure 101 and the lower side of the water channel, a screen 102 for trapping dirt that flows along with the water flowing into the water channel is provided in the vertical direction.

And, the known waste collection apparatus 1 is installed in front of the concrete structure 101 of the upper screen discharge conveyor (2) for discharging the waste collected from the screen to the outside, and the concrete structure behind the discharge conveyor (2) (101) The guide rail (3) horizontally installed by the column (3a) at a position higher than the discharge conveyor (2) on the upper side, and the movable frame (4) horizontally installed horizontally on the guide rail (3) And, while the tilting by the tilting cylinder (7) in the moving frame (4), the boom stand (5), and the rake (6) installed on the lower end of the boom stand (5) to scrape up the dirt caught on the screen 102 Is made of.

Since the waste collection device 1 is well known, a detailed description of the structure will be omitted. A detailed description of the structure and the working relationship of the known waste collection apparatus 1 will be described in detail below with reference to the publication of Patent No. 359267.

A rake cleaning device 27, which is a feature of the present invention, is installed downward below the tip of the moving frame 4 as shown in FIG.

As shown in FIGS. 3 and 5, the rake cleaning device 27 has horizontal supports 16 horizontally installed at both ends of the moving frame 4, and a pair of vertical supports at the lower ends of the horizontal support members 16. Support 17 is installed facing each other, between the lower end of the vertical support 17 on both sides is provided with a rotary cleaning device 19 rotated by the motor 18.

5 to 8, the pair of fixing plates 21 twisted 180 degrees to the outer circumferential surface of the rotating shaft 20 connected to the motor 18 as shown in FIGS. 22) is vertically installed to be fixed to the opposite side at intervals from the outer peripheral surface of the rotary shaft 20.

One side of each fixing plate 21 is bolted to the outer plate 24, which is twisted in the same manner as the fixing plate 21, with a blade 23 formed of a soft material such as a rubber material or a soft synthetic resin material. We install as).

At this time, the outer end of the blade 23 should scratch the upper surface of the rake 6, so the outer end of the blade 23 formed of a soft material such as rubber is the outer end of the fixing plate 21 and the outer plate 24. Note that it should be installed to protrude further outward.

Referring to Figures 3 to 8 the operational relationship of the present invention configured as described above is as follows.

When water flows down into a channel such as a sewage treatment plant, a drainage pumping station, a water intake plant, a small power plant, or other industrial sewage treatment plant, and the water flowing along the waterway contains waste, such as waste, on the screen 102 installed in the channel, The dirt is caught and water flows through the screen.

In this process, if a lot of dirt is caught on the screen 102, water does not flow properly. In this case, the rake 6 of the waste collection device 1 is lowered to the lower side of the screen 102 so that the tip of the rake 6 is removed. To the upper side in contact with the outer surface of the screen is to collect the dirt caught on the screen, the process is the same as that known in the prior art, so the description of the specific working relationship is omitted.

As shown in FIG. 4, after the soil is drawn up by the rake 6 as described above, the top surface of the rake 6 contacts the torsion blade 26 of the rake cleaning tool 27. To increase. As the boom 5 is raised in this manner, the rake 6 on which dirt is placed rises and then the top surface of the rake 6 comes into contact with the top surface of the torsion blade 26, thereby stopping the rise of the boom 5.

At this time, the stop of the boom 5 is to install the sensor 28 at a predetermined position under the vertical support 17 of the rake cleaning device 27 so that the rake 6 is close to the torsion blade 26. It is a well known technique that can be sensed to stop the boom 5 by sensing.

After the rake 6 on which dirt is placed is approaching the torsion blade 26 and the ascending of the boom 5 is stopped, the motor 18 installed in the rake cleaner 27 is driven to clean the rotary shaft connected to the motor shaft. Rotate the sphere 19.

Since the rotary cleaning device 19 is a torsion blade 26 for scraping dirt from the rotating shaft 20 to receive the power of the motor 18 is rotated as shown in Figures 5 to 8, the rotary cleaning device 19 As the) rotates, the torsion blade 26 scrapes the dirt placed on the top of the rake 6 downward.

When scraping the dirt down as above, since the position of the rake 6 is located above the discharge conveyor 2, the dirt scraped downward will fall to the discharge conveyor 2, and the discharge conveyor 2 will be horizontal. Since the dirt moves on the discharge conveyor 2, the discharge conveyor 2 will be discharged to the outside.

As described above, when the torsion blade 26 rotates the dirt on the rake 6 to the outside, the torsion blade 26 is disposed between the fixing plate 21 and the outer plate 24 as shown in FIG. Since the blade 23 formed of a soft material such as a rubber material is exposed to the outside, the outer end of the blade 23 scrapes dirt outward.

The torsion blades 26 are twisted by 180 degrees on the outside of the rotating shaft 20 so that a pair of the torsion blades 26 are scraped off while the pair of torsion blades 26 rotates the dirt in the form of screws. Soil having a predetermined length, such as plastic paper is to scrape the dirt down without winding the torsion blade (26).

As mentioned above, the torsion blade 26 has two blades 23 made of a soft material such as rubber in the middle so as to continuously scratch the upper surface of the rake 6 at intervals. The dirt on the floor is washed cleanly downward.

As the rake 6 sweeps downwards cleanly as described above, as the rake 6 is cleaned, another filth on the screen 102 is scraped and the dirt on the screen 102 is always cleaned. It will be scraped up and collected.

As described above, the rake cleaning device for the drainage device installed with the rake cleaning device of the present invention is installed with a rake cleaning device for sweeping the dirt on the top of the rake while rotating in the form of a screw in the front lower side of the moving frame of the waste collection device to the discharge conveyor. A pair of torsion blades that directly sweep the dirt on the pitchfork are twisted by 180 degrees at intervals on the outer periphery of the rotating shaft, so that the torsion blade is installed on the pitcher without the dirt being wound on the rotary cleaning device where the torsion blade is installed. Dirt can be wiped cleanly to the discharge conveyor side.

As the dirt on the top of the rake is always neatly knocked down, when you scrape up the dirt on the screen again and collect it, the garbage will be collected without leaving any residue on the screen. There is a very useful effect that does not occur.
