Description

[Detailed Description of the Invention] The present invention relates to a dust remover that uses brushes to prevent clogging of a mesh screen.

BACKGROUND ART Among conventionally used dust removers, one is known in which a screen bar is provided with a plurality of screen bars in the vertical direction.

However, in this type of device, the amount of dust that can be removed by the screen is limited to that which is larger than the size between the screen bars.

For this reason, various types of screens have been devised, but no one has yet been devised that can sufficiently clean the clogging.

The present invention solves these problems by installing a mesh screen under tension on the wall so as to cross the flow path.
A rear cleaning device is installed on the downstream side of the flow path to clean the clogging of the mesh screen by having a brush slide on the back side of the mesh screen using an elevating device; This device consists of a front rake device that slides on the upper surface of a wall extending above the mesh screen and transports the front rake in parallel with the mesh screen to rake up and discharge dirt.

The mesh screen may preferably be woven or have holes punched out.

Next, embodiments of the present invention will be described based on the drawings.

Reference numeral 1 designates a flow path, and the flow path 1 has an upper portion 2a tilted backwards so that the net screen 2 crosses it, and a wall 3 provided on the same plane as the net screen 2, giving sufficient tension. It is under tension.

Note that 2b is the eye of net screen 2.

4 is a rear rake device provided parallel to the downstream side of the net screen 2.

The rear surface cleaning device 4 is formed of a lifting device 5 and a brush 10.

The lifting device 5 has sprocket wheels 7.8 mounted on both sides of the upper and lower ends of the downstream side of the flow path 1 of the net I-screen 5, and an endless chain 9 suspended between the sprocket wheels 7.8 in parallel with the net screen 2. Then, brushes 10 are attached to the endless chain 9 at appropriate intervals.

The brush 10 is mounted on the upper surface of the side plate 11 by horizontally suspending the side plate 11 on the left and right endless chains 9, and the tip of the brush 10 is provided so as to slide on the back surface of the net screen 2.

12 is a front rake device installed parallel to the net screen 2 on the upstream side of the net screen 2;
A chain sprocket 14 is mounted above the upper part 2a of the net screen 2 and the wall 3 at 3, and front rakes 16 are attached to the chain 15 of the chain sprocket 14 at equal intervals.

The front rake 16 is provided in a comb-teeth shape so as to slide on the front side of the net screen 2.

17 is a chute formed at the upper end of the wall 3, 18 is a receiving tank, and 19 is a drive motor for the rear rake device 4 and the front rake device 12.

Thus, the rear cleaning device 4 is rotated clockwise or counterclockwise, and the front rake device 12 is rotated counterclockwise faster than the rear rake device 4.

The brush 10 of the rear surface cleaning device 4 slides on the back side of the net screen 2 to clean the dust stuck in the holes 2b of the net screen 2, and the front rake 16 of the front surface rake device 12
The dust is scraped upward along the net screen 2.

Next, the garbage raked up to the top of the net screen 2 by the front rake 16 is transferred to the E end of the wall 3 by the front rake 16 and is automatically thrown into the receiving tank 18 from the inclined chute 17.

Since the present invention is as described above, it has the following features.

1. By using the screw 1-screen 2 screen, it is possible to remove dust from the screw 1 to the screen 2 openings 2b and above.

Therefore, it is possible to remove even small particles that could not be removed conventionally, and the dust removal effect has been significantly improved.

2. Brush Rake 10 from the back side of Netsu I/Screen 2
The net screen 2 slides to clean any clogging, so that the mesh 2b is always free from clogging, preventing clogging, and minimizing fluid pressure loss due to the net screen 2, allowing water to flow smoothly.

3. A wall 3 on the same plane extends above the upper part 2a of the net screen 2, and the top of the wall 3 is lifted by the front rake device 16, so that the discharge height can be reduced. This is rational because it is not restricted by the net screen 2 and the rear surface cleaning device 4 and can be discharged at a desired height.
