Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a rotary dust remover capable of performing both screening work and dust removal work.

<Prior art and its problems> It is a reality that a large amount of debris floats and flows in rivers, waterways, etc., regardless of its size. Because garbage cannot be left unattended,
This must be removed by some means. A screen is used for this purpose.

The screens commonly used in the past were
As shown in the figure, a plurality of linear screen bars b are fixed in parallel at appropriate intervals in a river or waterway a, and water is passed through the gaps between the screen bars b, and garbage is removed by the screen bars b. It was structured so that it could be held against the ground. However, as is clear from the above, in this conventional example, the screen itself was fixed, so in order to remove the dust blocked by the screen bar b, a rake was required for the small screen. In the case of large screens, they were removed using a rake, as if raking them up. This work is done at regular intervals, but in any case, it is not only extremely complicated work, but also
The dust that is blocked by the screen bar b is not necessarily present only at the water surface position on the screen bar b, but also exists at the underwater position, that is, it is stuck to almost the entire surface of the screen due to the action of water pressure. Because it was stuck, removing it was not an easy task.

<Means for Solving the Problems> Therefore, in order to solve the above-mentioned problems, the rotary dust remover according to the present invention has ring-shaped screen bars arranged on both sides, and a structure in which a ring-shaped screen bar is arranged between these ring-shaped screen bars. A plurality of screen bars formed in a substantially C-shape are arranged in parallel with a desired interval maintained by a connecting bar, a bearing body is disposed on the ring-shaped screen bar, and a rotating shaft is disposed on the bearing body. Each screen bar can be freely rotated by a chain between a chain wheel disposed at one end of this rotating shaft and another chain wheel disposed above the rotating shaft of a rotating device such as a motor. At the same time, scraping claws are provided on the outer peripheral surface of each of the screen bars, or a dust receiving plate having a slit through which the screen bar is inserted is provided at the upper part in the rotational direction of the plurality of screen bars. The screen bar is installed to block the flow of garbage, the whole is rotated to guide the garbage above the water surface, and the garbage is forcibly removed at that part by its own weight or by the garbage receiving plate. In addition, it is also possible to remove dust that has entered the dust remover through the gap between the screen bars and stagnated there.

<Example> Next, an example of the rotary dust remover according to the present invention will be described based on the drawings. Reference numeral 1 denotes a screen bar formed in a substantially C-shape;
are arranged in parallel at desired intervals. Reference numeral 2 denotes a ring-shaped screen bar disposed on both sides of the plurality of screen bars 1, and a cross-shaped bearing body 3 is disposed on this ring-shaped screen bar 2. In order to arrange a plurality of screen bars 1 in parallel and integrally connect them to a ring-shaped screen bar 2, a connecting bar 4 is arranged on the inner peripheral surface of each screen bar 1 and ring-shaped screen bar 2. is being carried out. As a result, each substantially C-shaped screen bar 1 between the ring-shaped screen bars 2 on both sides appears as if it were a cylindrical cage-like body having an opening in a part. Reference numeral 5 denotes scraping claws arranged at desired intervals on the outer peripheral surfaces of the screen bar 1 and the ring-shaped screen bar 2, and the scraping claws 5 are provided independently on each screen bar 1 and the ring-shaped screen bar 2. It is formed to have a width that is equal to or narrower than the width of each screen bar 1 and ring-shaped screen bar 2. Reference numeral 6 denotes a rotating shaft, and this rotating shaft 6 is fixed to the bearing body 3 of the ring-shaped screen bar 2, and one end thereof is connected to a desired rotating device. This rotating device may be a motor, for example, but
In the illustrated embodiment, a chain wheel 7, a chain wheel 8, a chain wheel 7', and a reducer 9 are connected to a handle 10. Therefore, by rotating the handle 10, the screen bar 1 etc. are rotated via the chain 8. Reference numeral 11 denotes a fixed dust receiving plate disposed above the screen bar 1 in the rotational direction, and this dust receiving plate 11 has a slit having a width necessary for the screen bar 1 to pass through. In addition, 12 in the figure is a collection place set behind the garbage receiving plate 11.

<Function> A dust remover formed into a cylindrical cage-like body using the screen bar 1 or the like is installed in the transverse direction of a river or waterway. As a result, the garbage becomes stuck on the screen bar 1 and/or the ring-shaped screen bar 2 over time. Since water passes through the gap between each screen bar 1 and the ring-shaped screen bar 2 in the downstream direction, the water acts as a screen.
In order to remove the stuck garbage, hold the handle 10 and turn it, and the torque will be applied to the reducer 9.
The rotating shaft 6 is rotated via the chain wheel 7' and the chain wheel 7, and the screen bar 1 and the like are also rotated. In this case, the dust adhering to the screen bar 1 etc. is lifted above the water surface by the adhering state or by the action of the raking claws 5. For example, in the case where there is no dust receiving plate 11, that is, in the case of the invention described in claim 1, the dust adhering to the screen bar 1 etc. is removed from the topmost layer by the rotation of the screen bar 1 etc. When the dust reaches a stage where it eventually descends, it may naturally separate from the screen bar 1 etc. due to its own weight and fall into the collection area 12. Dead leaves and the like stick together under water due to water pressure, but on the surface of the water there is no water pressure and they may separate naturally.
However, in order to remove the dust more reliably, the invention described in claim 2, that is, the dust receiving plate 11 is used. In other words, each screen bar 1 passes through the slit of the dust receiving plate 11 during its rotation, so that the dust adhering to the outer peripheral surface of the screen bar 1 is scooped out by the dust receiving plate 11. It is removed like this. The removed garbage moves to the collection site 12 while sliding on the upper surface of the garbage receiving plate 11.

Further, dust that has entered the interior through the gaps between the screen bars 1 or dust that has entered the interior through the openings during rotation of the screen bars 1 may be removed manually from the openings. However, theoretically, this amount of dust is extremely small.

<Effects of the Invention> As described above, according to the rotary dust remover according to the present invention, ring-shaped screen bars are arranged on both sides, and a plurality of screens formed in a substantially C-shape are arranged between these ring-shaped screen bars. The bars are arranged side by side with desired spacing maintained by connecting bars, a bearing body is disposed on the ring-shaped screen bar, a rotating shaft is disposed on the bearing body, and a rotating shaft is disposed on one end of the rotating shaft. Each of the screen bars is rotatably arranged by a chain wheel and another chain wheel arranged on the rotation axis of a rotating device such as a motor arranged above the chain wheel, and each of the screen bars is rotated. Scraping claws are provided on the outer circumferential surface, and a dirt receiving plate having a slit through which the screen bar is inserted is provided at the upper part of the screen bar in the rotational direction, so that the screen bar does not remove the dirt. The flow of the dust is blocked by rotating the whole body, and the dust is guided above the water surface, and the dust is forcibly removed at that part by its own weight or by the dust receiving plate, and the dust is removed from the gap between the screen bars. This has the effect of being able to remove debris that has entered the interior of the machine and stagnated there.
