Abstract

PURPOSE:To prevent rake from becoming unoperable by biting screen residue by making the rake vertically movable while allowing the rake to contact freely with a screen by hanging down the rake with wire rope, etc. CONSTITUTION:The weel of a rake 34 is allowed to contact with the bottom of a water layer while holding the rake vertically by winding down a drum 26. The drum is wound up from this state to hold the rake 34 horizontal and the wheel 35 of the rake 34 is made to contact with the surface of the screen 12. Then, both drums 26, 28 are wound up and the rake 34 is lifted. Screen residue 42 suspended in the water passage 10 is caught by the rake 34 and brought up. A transversally movable club 22 is moved onto a belt conveyor 36: the first drum 26 is wound up and the rake 34 is titled, and the screen residue 42 is dropped on the conveyor 36.

Description

[Detailed description of the invention] The present invention relates to an automatic dust remover, particularly for sewage treatment plants.

Attached to settling ponds at sewage pump stations, etc., the screen collects debris floating in the inflowing sewage.

This invention relates to an automatic dust remover that automatically and continuously scrapes up and removes dust.

The automatic dust removal device conventionally used in this type of splitting is.

It consists of a traveling device, a rake raising and lowering device, a rake fixing device, and a pusher device. However, the structure of such a conventional automatic dust removal device is complicated, and floating particles are forcibly lifted up.
Since it is transported using a butt shear, depending on the shape of the scum, the scum often gets caught in the screen, which often causes the equipment to stop due to overload.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a reliable automatic dust removal device that will not stop due to overload or the like even if residue gets caught on the screen surface.

In order to achieve the above object, the present invention provides a sludge removal screen disposed in a waterway, a running lane running on rails laid on the waterway in the width direction of the waterway, and a running lane. A movable club that is movably supported, a rake that is suspended from the movable club by a rope or the like on the screen side and the opposite side, and that scrapes up the scum on the screen surface and conveys the scum that has been scraped up to a discharge section, and the movable club. The rake is characterized by comprising a first drum for winding and lowering a rope, etc. which is mounted on the rake and supports the screen side of the rake, and a movable club.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the automatic dust removal apparatus according to the present invention will be described in detail below with reference to the drawings.

A plurality of water channels 10 are arranged in parallel, and inside the water channels 10, sewage and the like containing floating residue flows as shown by the arrows in FIG. A screen 12 is disposed within the waterway 10, and by this screen 12, sludge suspended in the waste water of the waterway 10 is collected in front of the screen 12. The upper surface of the water channel 10 is closed by a floor plate 14.

A rail 16.1 is placed on this floorboard 14 in the width direction of the waterway 1o.
6 has been installed. On this rail 16.16, a running 1/- 18 is supported so as to be movable along the rail 16.16. That is, the rollers 20.20 provided at the lower end of the running lane 18 are provided on the running rail 16.16, and the running lane 18 can be moved in the width direction of the waterway 1o by the rollers 20.20. Reference numeral 21 in FIG. 2 is a drive motor for the corro hakama 20.

A horizontally moving rub 22 is provided at the top of the running lane 18, and this horizontally moving rub 22 is movable in the left-right direction in FIG. 1 via running wheels 24.24 supported at the top of the running lane 18. It is. The horizontal love 22 has the first drum 2.
6. A second drum 28 is mounted, this drum 26.2
A wire rope 30, 32 is suspended from the 8 frame so that it can be rolled up and lowered. Furthermore, a rake 34 is supported at the lower end of the wire rope 3o32. The wire rope 3Q supports the screen 12 side of the rake 34, and the wire rope 32 supports the end of the rake 34 on the opposite side to the screen 12. Therefore, by operating the winding drums 26 and 28, the rake 34 can be positioned vertically,
It is possible to position the rake 34 horizontally or to raise and lower the rake 34. Note that a wheel 35 is provided on the right side of the rake 34.

A belt conveyor 36 as a discharge section is provided on the floor plate 14 of the waterway 10, and a neat 38 is provided adjacent to this belt conveyor 36.

A driver's cab 40 is provided in the lane 18 in which the vehicle is traveling, and a worker can operate the rake 34, etc. in the lane 18 in which the vehicle is traveling.

The operation of this embodiment configured as described above is as follows. First, as shown in FIG. 3, the drum 26 is completely lowered, the rake 34 is maintained in a vertical position, and the wheels 35 of the rake 34 are brought into contact with the bottom of the water. From this state, the drum 26 is hoisted, the rake 34 is made horizontal as shown in FIG. 4, and the wheels 35 of the rake 34 are brought into contact with the surface of the screen 12. From this state, both drums 26 and 28 are wound up and the rake 34 is raised. In this case, the rake 34 is wire rope 30°32
Since the rake 34 is suspended and lifted up, it functions as a cushioning device, and the rake 34 rises in a free state, so even if scum 42 or the like gets caught between the rake 34 and the screen 12, the automatic dust removal device cannot run. There is no such thing as falling into. When the rake 34 picks up the sludge 42 floating in the waterway 1o and rises to the position shown in FIG. The first drum 26 is lowered, the rake 34 is tilted, and the residue 42 is dropped onto the belt conveyor 36. After dropping the sludge 42, the drum 26 is wound up again, the rake 34 is hoisted horizontally, the lane 18 running to the primary waterway is moved along the running rail 16, and the above-described operation is repeated again. Meanwhile, the residue in the water channel 10 is removed.

In the above embodiment, the rake was raised and lowered by hoisting and lowering the wire rope 32, but the invention is not limited to this; an electric chain hoist is used, and the rake 34 is raised and lowered by a chain. may be raised or lowered.

As explained above, according to the automatic dust removal device according to the present invention, the rake is lifted and lowered by being suspended by a wire rope, etc., so that the rake comes into contact with the screen that collects scum in a free state, and the rake is moved up and down on the screen. Since the accumulated sludge is raked up, the rake will not become inoperable due to L sludge being caught, and any type of sludge can be efficiently removed.
