Description

[Detailed Description of the Invention] The present invention relates to a dust removal device that is installed in a waterway and removes debris flowing through the waterway.

In a dust removal device in which a screen is disposed across a waterway, the residue adhering to the screen is scraped up by a rake driven by an endless rotating chino, and then dumped into a discharge section at the upper part of the waterway, in the vicinity of the lower end of the screen. In some cases, a sprocket around which the endlessly rotating chino is wound is arranged.

In this case, it is essential to install an avant-garde screen in front of the sprocket in order to block the sludge flowing on the bottom of the channel without blocking the flow of water at the bottom of the channel.

However, if residue adheres to this avant-garde screen, a person must sometimes descend to the bottom of the waterway and clean it manually, which poses a problem in that the environment is poor and the work is difficult.

The object of the present invention is to provide a dust removal device that can easily clean the avant-garde screen, and one embodiment thereof will be described below with reference to the drawings.

First, the general structure of the entire dust removal apparatus, which is an embodiment of the present invention, will be explained with reference to FIG. 1. Reference numeral 1 denotes a groove-shaped waterway, and a screen 2 is provided in an inclined position across the waterway.

The screen 2 consists of a large number of vertical plates arranged in parallel in the width direction of the waterway 1.

Reference numeral 3 denotes a guide plate that extends above the screen 2, and the upper end of the guide plate 3 is bent into an arc so as to be reversed toward the rear with respect to the flow direction of the waterway. A chute portion 4 is formed.

Reference numeral 5 denotes a pair of endless rotary chinos arranged on both sides of the screen 2 and the guide plate 3, with a lower sprocket 6 arranged below the lower end of the screen 2 and an inner side of the arc-shaped part at the upper end of the guide plate 3. It is wound between the upper sprocket 7 and the upper sprocket 7, which is driven to rotate around the located axis.

The endless rotating chino 5 includes the screen 2 and the guide plate 3.
The upper sprocket 7 rotates around the outside of the chute section 4 at the upper end of the guide plate 3, and then the guide plate 3
Then, it descends on the back side of the screen 2 and returns to the lower sprocket 6.

Rakes 8 are attached between the pair of endless rotary chess 75 at appropriate intervals in the longitudinal direction of the chess to scrape up the residue attached to the front surface of the screen 2.

Reference numeral 9 denotes an intermediate sprocket disposed below the sludge dropping chute section 4, which guides the endless rotary chino 5 so that the rake 8 moves along the outer surface of the sludge dropping chute section 4.

Reference numeral 10 denotes a cover provided at an interval on the outside so as to cover the guide plate 3 portion, and includes the aforementioned residue dropping chute portion 4.
A discharge port 11 is formed directly below the discharge port 11, and a discharge conveyor 12 is installed below the discharge port 11.

13 is an inspection window provided at a position in front of the guide plate 3 at the bottom of the cover 10, and 14 is an inspection window provided above the inspection window 13 and facing the upper sprocket 7.

Reference numeral 15 denotes a drive device for rotationally driving the upper sprocket 7, and 16 a pedestal for supporting the upper sprocket 7 and the drive device 15.

In this dust removal device, a vanguard screen 17 is disposed in front of the lower sprocket 6.

The vanguard screen 17, as shown in FIGS. 2 to 4,
The guide groove 18 is provided on both side walls 1a of the waterway 1 from the bottom of the waterway to the top end of the waterway, and is guided so as to be able to rise and fall.

That is, on both sides of the vanguard screen 17, shoes 17a are protruded at the upper and lower positions, respectively.
a is fitted into the guide groove 18.

Further, the cover 10 is provided with a guide rail 19 forming a guide groove continuous with the guide groove 18, and the guide rail 19 extends at least to a height opposite to the inspection window 13.

Thus, the avant-garde screen 17 can be raised and lowered freely between the waterway bottom position (shown by a solid line in FIG. 2) and the position facing the inspection window 13 in the cover 10 (shown by a phantom line in FIG. 2).

Reference numeral 20 denotes an element body such as a wire rope or wire rope whose one end 20 a is connected to the upper end of the vanguard screen 17 , and whose other end is wound around a winding drum 21 rotatably supported by the cover 10 on the frame 16 . It has been taken.

Reference numeral 22 denotes a drive sprocket fixed to the shaft of the winding drum 21, and is rotationally driven by a drive motor 23 installed on the pedestal 16.

Next, to explain the operation, when the drive device 13 is driven to rotate the endless rotary chino 5, the rake 8 sticks to the front surface of the suffoon 2, scrapes up the residue, and the residue is removed by the residue dropping chute 4. It is dropped downward and carried out by the discharge conveyor 12.

On the other hand, when residue adheres to the vanguard screen 17, the drive motor 23 is driven to wind up the cord 20 on the winding drum 21, the vanguard screen 17 is raised along the guide groove 18 and the guide rail 19, and the inspection window Pull up to position 13.

Then, the vanguard screen 17 is cleaned through this inspection window 13.

When cleaning is completed, the avant-garde screen is lowered by driving the drive motor 23 in reverse rotation and is reinstalled at its original position on the bottom of the waterway.

Note that the guide groove 1 is used as a guide means for the vanguard screen 17.
8 and shoe 17a, but it is also possible to use means such as providing guide ridges on both side walls of the waterway and providing grooves or guide rollers on the avant-garde screen that engage with the guide ridges. You can also do it.

According to the dust removal device of the present invention, as is clear from the above explanation, the avant-garde screen can be arbitrarily raised to a position above the waterway, so the avant-garde screen can be cleaned safely and easily in a good working environment. Once cleaning is complete, it can be easily reinstalled in its original position.
