Description

[Detailed explanation of the idea] [Technical field of invention] This invention relates to a dust remover.

[Background Art] Dust removers are installed at river water intakes, drainage pump stations, and settling ponds at sewage treatment plants.

There are various types of dust removers, but for example, an electric motor or a hydraulic cylinder is used as the drive means, and a bending type link mechanism is connected to the drive means so that the link mechanism Some have a rake at the tip.

However, since it is similar to this dust remover, the overall structure is complicated, which not only increases costs, but also requires laborious installation work, as well as maintenance and inspection. It is.

[Purpose of the invention] This invention not only simplifies the overall structure and reduces costs, but also makes the installation work very simple and quick, and also makes maintenance and inspection very easy. The purpose is to provide an opportunity.

[Structure of the invention] In order to achieve the above object, this invention is a dust remover having a screen that looks into the waterway, a rake for scraping, and a lifting means for raising and lowering the rake, the lifting means being , a hoist located above the device, and a rake guide connected to the lower end of a wire of the hoist to guide a rake in the vertical direction, and the screen can take a posture substantially perpendicular to the backward tilted posture. It is characterized by the fact that it has become possible.

[Example] Hereinafter, an example of this invention will be described with reference to the drawings.

1 and 2 show an embodiment of this invention. As shown in these figures, the waterway 1 is
It is formed by a bottom wall 2 and a top wall 3.
A constant water level is set within the waterway 1. Water flows from left to right in Figure 1. The upper wall 3 has a plurality of openings 3a in a direction perpendicular to the paper surface of FIG.
is formed.

4 is a hinge provided on the bottom wall 2. The lower end of the screen 5 is connected to the hinge 4. This screen 5 is formed by connecting a number of bars with gaps, and the lower end 5a
is bent in a dogleg shape so that the front side is concave.

On both front sides of the screen 5, rake guides 6, 6, which are formed in a dogleg shape like the screen 5, are fixed by stays 7 so as to be parallel to the screen 5. Screen 5 is 75
It is possible to change the posture between leaning backwards to a degree and standing up almost vertically. As the attitude changing means, a cylinder 8 is installed on the top wall 3, and this cylinder 8 is connected to the screen 5.
is connected to the upper end of the

A roller guide 9 is installed at a position corresponding to the extension line of the rake guide 6 in the vertical position so as to expand upward and downward. Ceiling rail 1 corresponds to the upper part of this roller guide 9.
0 is provided on this ceiling rail 10,
A hoist 11 is provided so as to be freely movable.

A wire 12 is suspended from the hoist 11, and a rake 13 is attached to the lower end of the wire 12.
is installed. This rake 13 is formed into a bucket shape, and two rollers 14 are attached to both sides of the rake 13, each on the left and right sides, which are guided by the rake guide 6 and roller guide 9.

The screen 5 is tilted backwards, and a large amount of wood and dirt accumulates in front of the screen 5. At that time, the rake 13 is lifted up by the hoist 11.

If a large amount of wood or debris accumulates, cylinder 8
As a result, the screen 5 is tilted forward and made almost vertical, so that the rake guide 6 corresponds to the roller guide 9. In this position, the hoist 11 is driven and the rake 13 is lowered. As a result, the roller 14 is guided by the roller guide 9, so that the rake 13 descends along the rake guide 6.

When the rake 13 reaches the lower end of the rake guide 6, it scoops up wood, dirt, etc., and then rises to scoop up the wood, etc. in front of the screen 5 at the same time. The rake 13 is lifted above the opening 3a by a hoist 11 through the roller guide 9, and then removed to a predetermined processing site by a ceiling rail 10. Thereafter, the screen 5 is tilted backward by the cylinder.

Although the hoist 11 is provided for each dust remover, one hoist 11 may be provided for a plurality of dust removers.

Further, the roller guide 9 is installed so as to correspond to when the screen 5 is in a backward tilted position, and the rake 13 is configured to descend through this roller guide 9 and rise through another roller guide 9. can do.

[Effects of the invention] As explained above, this invention is a dust remover that has a screen that looks into the waterway, a rake for scraping, and a lifting means for raising and lowering the rake, and the lifting means has the following features: It has a hoist located above the device and a rake guide that guides a rake connected to the lower end of the wire of the hoist in the vertical direction, and the screen can take a posture substantially perpendicular to the backward tilted posture. Since this dust remover is characterized by the following features, not only the overall structure is simple and costs can be reduced, but the installation work is very simple and quick, and maintenance and inspection are also very easy. This makes it possible to provide a dust remover that can perform the following tasks.
