Description

[Detailed explanation of the invention] (Industrial application field) This invention is applicable to rivers/intake channels, water/sewage treatment plants,
The present invention relates to a traveling type dust remover that scrapes up and removes debris from a plurality of dust removal screens having two or more types of spans installed in waterways or water intakes of wastewater treatment plants, etc.

(Prior Art) Conventionally, a dust remover installed at a water intake or the like where multiple dust removal screens are installed in parallel is mounted on a trolley that runs on rails, and one dust removal rake is driven by a drive device. It is designed to be raised and lowered (see, for example, Japanese Utility Model Publication No. 8105/1983).

The rake for the dust removal screen at the water intake, which has two types of spans, large and small, has a width that is large enough to remove dust from the small span. is raised and lowered several times sequentially from the end in the width direction.

(Problem to be solved by the invention) By the way, with the above-mentioned conventional traveling type dust remover, when removing dust from a large-span dust removal screen, it is necessary to perform lifting and lowering operations multiple times, resulting in extremely low work efficiency. The problem is that it's bad.

In addition, installing a dust remover with a rake that fits each span in order to improve dust removal efficiency would require a large amount of money and be uneconomical. There is a problem in that it cannot be secured due to the relationship with the adjacent dust remover.

This idea was devised in view of the above-mentioned circumstances, and its purpose was to create an economical dust remover that could efficiently remove dust from water intakes with multiple spans of different sizes. It is on offer.

(Means for solving the problem) In order to achieve the above purpose, the following technical measures were taken in this invention.

In other words, this invention is a traveling type dust remover that scrapes up and removes the garbage hanging on multiple dust removal screens installed at water intakes with two or more spans such as waterways or water treatment equipment. The invention is characterized in that two types of rakes, large and small, are arranged closely in parallel, and each rake is configured to be operated separately or simultaneously by a separate drive device.

(Function) According to this invention, two types of rakes, large and small, are used separately to remove dust from the water intake in the span corresponding to each rake width. By removing dust from the water intakes of the spans with the size of the above-mentioned spans, it is possible to perform the dust removal work of the water intakes of at least three types of spans in one operation.

That is, by operating the large and small rakes separately or simultaneously to remove dust, it is possible to remove dust from three or more types of spans.

(Example) Hereinafter, an example of this invention will be described based on the drawings.

In the drawing, 1 is the embankment body, 2, 3, 4, 5 are water intakes with different spans provided on the embankment body 1, 6, 7,
8 and 9 are dust removal screens installed at each water intake;
10 is a dust remover, and dust removal screens 6 to 9 are placed on the embankment body 1.
It is equipped with a trolley 12 that is mounted on rails 11 laid parallel to and runs along dust removal screens 6 to 9, and screens 6 to 9 between two rails 11.
9 A garbage carrying conveyor 13 is installed on the downstream embankment body 1.

The trolley 12 is provided with a front apron 14 having the same inclination angle as the screen so as to continue to the upper end of the dust removal screens 6 to 9, and guide the garbage from the upper end of the apron 14 to the discharge conveyor 13 on the downstream side. A garbage discharge chute 15 is provided.

The dust remover 10 includes the truck 12 and the truck 1.
2, a frame 16 erected on the frame 16, a bogie running drive means 17, and an extendable rake arm 18 pivotally supported by the frame 16 so as to be swingable in the front and rear directions (upstream and downstream directions).
19, large and small rakes 20, 21 attached to the lower ends of the arms 18, 19, rake arm swing cylinder devices 22, 23, and arm telescopic drive device 2.
It is composed of a 4,25 rake opening/closing device (not shown), etc.

The rake arms 18 and 19 are controlled by separate swing cylinder devices 22 and 23 so that they can be synchronously interlocked separately or simultaneously.
Further, the extension and contraction operations of the rake arms 18 and 19 are also controlled by separate drive devices 24 and 25 so that they can be synchronously interlocked separately or simultaneously.

Furthermore, the opening/closing operations of the large and small rakes 20 and 21 are controlled by separate drive devices, respectively, or in a synchronously interlocked manner.

Therefore, according to the above embodiment of this invention,
Using the larger rake 20, the debris hanging on the dust removal screen 8 of the water intake port 4 corresponding to the width of the rake is removed by the rake arm swinging cylinder device 2.
2. It can be removed by driving the arm extension/contraction drive device 24 and rake opening/closing device. In addition, the smaller rake 21 independently drives the rake arm swinging device 23, the arm telescoping drive device 25, and the rake opening/closing device to remove debris hanging on the dust removal screen 7 of the water intake port 3 corresponding to the width of the rake. do,
Can be removed.

Furthermore, the dust hanging on the dust removal screen 9 of the water intake port 5, which has a span larger than the width of the large rake 20, can be removed by arranging the large and small rakes 20, 21 and using the rake arm swing cylinder devices 22, 23,
By simultaneously operating the arm telescopic drive devices 24, 25 and the rake opening/closing device in synchronization, it is possible to rake up and remove the debris in one go.

In addition, when designing waterways and water intakes 2 to 5,
The width of the water intakes 2 to 5 should be determined in relation to the width of the rakes 20, 21 of the dust remover 10.

In addition, in the case of a water intake with two types of spans,
A small rake with a width corresponding to the difference between the large and small water intake widths and a large rake with a width corresponding to the small water intake width may be used.

In the above embodiment, the dust remover 10 is of the swing arm type, which is equipped with a telescoping arm and is swingable, and is also equipped with a rake opening/closing device. Of course, it is also possible to employ a dust remover of the type described above, or a dust remover of the type in which a rake is attached to an endless chain. Furthermore, each drive device may also be mechanical, hydraulic, or the like.

(Effect of the invention) As mentioned above, the dust remover according to this invention has two types of rakes, large and small, arranged side by side, and each rake is configured to be operated separately or simultaneously by a separate drive device. Therefore, by operating each rake individually or in synchronization at the same time, it is possible to remove debris from the dust removal screens of water intakes with two or more spans at the same time. Dust removal is possible, and the efficiency of dust removal work can be improved.

Furthermore, since there is no need to install a separate dust remover for each span, there is no problem with the means for discharging and transporting garbage, and it is extremely economical because it does not require a large amount of expense.
