Description

[Detailed description of the invention] This invention relates to a dust remover installed in waterways of water and sewage treatment plants, intake channels, other waterways and rivers, etc.

Conventionally, the upstream and downstream gate-shaped dust removal mechanism frames were built across the waterway, guide rails were installed on both sides of the waterway, and a short-shaped scrubber tray that was raised and lowered while being guided by the guide rails. A dust remover is known that is comprised of a screen having a section and a screen lifting device.

When working with such a dust remover, usually either the upstream or downstream screen, for example, the upstream screen, is lowered into flowing water, and the downstream screen is raised.

If left in this state, floating matter such as dust will accumulate on the front of the screen over time, so at an appropriate time, switch to the downstream screen.

To make this changeover, the downstream screen is first lowered into the flowing water of the waterway, and then the upstream screen is lifted up by its lifting device, and a worker scrapes off the debris on the screen.

As described above, the conventional dust removal machine has a problem in that the scraping off of the collected garbage must be done manually by the operator, which is extremely inefficient.

This invention was made to solve the above-mentioned problems, and will be explained in detail below with reference to the drawings showing the configuration of an embodiment.

The dust remover according to this invention has upstream and downstream gate-shaped dust removal mechanism frames 2 and 3 built across the waterway 1, and approximately sickle-shaped guide rails 4 and 5 erected on both side walls of the waterway 1A. The dust removal screen 6.7 consists of a roughly shaped dust removal screen 6.7 that is raised and lowered guided by the guide rails 4 and 5, and screen lifting and lowering devices 8 and 9. Guide rollers 10 and 11 are pivotally attached to the lower part, and the upper guide roller 10 protrudes laterally than the lower guide roller 11 so as to connect the guide rails 4 and 5.
The upper ends of the guide rails 4 and 5 are made to protrude forward on the upstream side to form arcuate -L portion guide roller guide portions 4A and 5A, and the guide rails 4. Lower guide roller guide portions 4B, 5B, which are located above the upper surface of the waterway side wall and are partially cut out and protrude in a curved shape forward, are placed on the upstream side surface of the lower guide roller guide portion 5. Dust removal screens zl-flanges 12 and 13 are provided in front of the screen 5B.

This stopper 12j3 has a roller shape and is rotatably attached to the frame 2.
, 3 mounted on the front, dust removal screen>'6.

The lower end horizontal portions (rake-like) 6A and 7A are brought into contact with the tips on both sides of the upper surface, and the screen 6.7 is prevented from rising any further and is rotated forward about this, causing the horizontal portion 6A to rotate forward. , 7A is tilted and the garbage thereon is dropped onto garbage receiving troughs 14 and 15 provided in front across the waterway 1.

The arcuate guide surfaces of the upper guide roller guide portions 4A, 5A of the guide rails 4, 5 have their curvature centers centered on the lower surface of the stopper 12.13, and the arcuate guide surfaces of the lower guide roller guide portions 4B, 5B The surface is upper guide roller 1
0 can be transferred smoothly, and the screen 6.7 comes into contact with the stopper 12.13 to facilitate forward rotation.

Note that the two-part guide roller 10 is the lower guide roller 1.
The lower guide roller guide portion 4 is positioned outwardly than the lower guide roller guide portion 4.
Since B and 5B are formed closer to the inside than the upper guide roller rolling portion, the lower force idle roller guide portion 4B,
5B can be passed without any trouble.

The screen lifting devices 8 and 9 are spindle type performance machines,
The lower end of the spindle 16.17 is pivotally connected via a pin 20.21 to a mounting bracket 18.19 projecting from the center of the rear surface of the lower end of the screen 6.7.

Note that the screen lifting devices 8 and 9 can be a spindle-type hoist with a swoop device, or can be a rope-type hoist with one end of the rope tied to the mounting bracket 18 or 19. Either or both of the power sources can be used.

According to the dust removing machine according to this invention, when the upper and downstream screens 6.7 are pulled up and down by the respective screen lifting devices 8.9, the upper guide roller 10 moves to the guide portion 4A of the guide rails 4 and 5. , just before touching the corner of 5A,
The lower guide roller 11 abuts against the stopper 12.13,
When the screen 6.7 is further pulled up, the upper guide roller 10 rolls on its guide portions 4A and 5A, and the lower guide roller 11 is guided by its guide portions 4B and 5B and rotates forward as shown in FIG. Lean forward as shown by the two-dot chain line.

At this time, the horizontal portions 6A, 7A1 .
The garbage slides down and is received on the garbage receptacles 1 to 14 and 15.

Next, when lowering the screen 6.7, the screen lifting devices 8 and 9 are used to push it down 2, and the screen 6.7 is moved by the stoppers 12 and 13 and the guide roller 11 of the upper guide roller 10. When the upper guide roller 10 reaches the upper end corner of the guide rails 4 and 5, the screen is rotated backward by assisting the transfer.
- The horizontal parts 6A and 7A become horizontal and are lowered into flowing water in that state.

When operating the dust remover, if one of the upstream and downstream screens 6.7 is under running water and you want to replace it with the other, first lower the other screen into the running water, and then remove the dust. It is the same as the traditional method of lifting the hanging screen.

The dust remover according to this invention has an abbreviated screen 6.7 in which the rake and screen are integrated as described above.
Since the garbage is guided by the approximately sickle-shaped guide rail 4.5 and tilted forward at the upper limit, the garbage is automatically dropped onto the garbage receiving troughs 14 and 15, which eliminates the need for manpower and improves work efficiency. In addition, the structure is simple, easy to manufacture, trouble-free, inexpensive, and easy and smooth to operate.
