Abstract

PURPOSE:To collect the dust efficiently, and prevent blinding by providing bar screens in the central part of a flow passage, and providing flow-in ports of the waste water and exhaust ports of the purified water in both sides of the bar screens, and providing a rake device for turning around of the periphery of the bar screens. CONSTITUTION:Partitions 3, 3, partition pillars 4, 4, and bar screens 5, a bypass gate 7 and a rake device 9 for turning around of the bar screens 5 are provided in the central part of a flow passage 1 of a dust collecting equipment. The bar screens 5 are provided in the waste water flow-in ports and the filtered water exhaust ports. The bypass gate 7 is bridged between the partition pillars 4 so as to be elevated freely by an elevator 8. Furthermore, a rake device 9 for turning around of the peripheral surface of the bar screens 5 is provided. The water flow passage 1 is thereby divided into water flow passages 6 by the bar screens 5 and the bypass gate 7, and the impurity is caught by the screen surface to flow only the waste water and exhaust the filtered water.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention introduces water from the outer surface of a U-shaped bar screen, flows into the center of the bar screen, and rake along the outer periphery of the bar screen. Move and remove dust 5
J: It is the one that removes uni and xij: 1ν1.

[Conventional technology]

Generally, a dust remover is equipped with a bar screen that blocks the running water of the waterway, and the bar screen captures the dirt in the running water, which is then scraped into a rake for 10 minutes. There is.

[Problem to be solved by the invention]

If a bar screen is set up to block the waterway, it is not possible to install a bar screen only at the maximum cross-sectional area of the waterway, and in order to capture the screen water from a large area, it is necessary to increase the cross-sectional area of the waterway. There is a need to.

Also on the bar screen! In order to clean the bath screen which has been blocked by the flow of inflow water without clogging, the effect of Iq is lowered by more than 1.

In the present invention, the shape of the bar screen and the lAE in the waterway are
The objective is to be able to remove dust by directing human hydraulic water, and to be able to clean the bar screen without stopping the flow of water even if clogs form.

[Means to solve the problem]

The present invention was made in order to achieve the above-mentioned Thl objective-1, in which a U-shaped bar screen is installed in the center of a waterway, and a latch is inserted into the bar screen from both sides of the bar screen into the waterway. An inflow is provided so that the filtrate flows out,
In addition, the bar screen is provided with a 4JI outlet 11 for discharging filtered water, and a rake device that moves around the outer peripheral surface of the U-shaped bar screen.

[For production]

A U-shaped bar screen is installed in the center of the waterway if L
Since water is allowed to flow into the outer peripheral side surface of this bar screen, compared to conventional screens, the water filtration area of the screen can be expanded even in waterways with a large cross-sectional area. Since the rake is operated around this bar screen, the screen residue captured by the screen can be scraped up effectively.

Furthermore, the water that was introduced inside the outer circumferential side of the bar screen is inside one side of the bar screen! II
J, ri channel side - 5 is guided, and a bypass gate is provided on the other side, so 11 clogging occurs in the bar screen, and I residual dust 4' + work is 4 no:' + l: L, but this By opening the bypass gate 1, it is possible to prevent an unexpected lf failure without stopping the water flowing into the waterway.

〔Example〕

Hereinafter, the dust remover of the present invention will be explained based on the illustrated embodiment.

In the figure] is a waterway in the dust removal equipment, and inside this waterway, there is a partition wall with a flow path 2 only in the center: 3.3, which protrudes inward.
3J: Two bulkhead pillars ``J'' on the side 4. /I
1171 Partition wall 3. : A bar screen 5 in the shape of 1 is placed and fixed between this partition wall and the partition wall pillar 4. Therefore, the partition wall pillars 4 and 4 are parallel to each other. The interval and the width of the flow passage 20 are made approximately equal to the U-shaped width of this U-shaped bar screen, and the side surfaces of the bar screen are fixed to the partition wall 3 and the partition pillar 4, respectively.

Since this bar screen 5 is installed in the center of the waterway 1, water flow passages 6, 6 are provided on the outside of both sides of the bar screen.
is formed. Therefore, the water introduced into the water channel 1 is diverted to the water passages 6.6 on both sides of the water channel by the partition pillars 4, 4 and the bypass gate 7 which moves up and down along the partition pillars. That is, water flows into the inside of the U-shaped bar screen 5 on both sides of the bar screen, passes through the flow path 2 formed by the partition wall 3.3, and flows out of the outlet l\ inside the bar screen. When flowing through this bar screen, foreign M objects are captured on the screen surface.

The bypass gate 7 is arranged along the upstream side of the pillars so as to bridge between the partition pillars 4 and 4 in the IT1 row, and is supported so as to be freely lowered by the rj/timer 8 provided in a part. -1.7 is set to prevent the water introduced into the water channel 1 from short-circuiting and flowing directly into the bar screen without passing through the outer peripheral side of the bar screen when the bar screen is in the drop position; And -1-shi 1' position is inside the waterway J:sl
＋'I4'3 This is to allow water to flow into the bar screen, and determine its size and lifting height appropriately.Furthermore, in order to allow the gate to move up and down smoothly, a guide rail is installed on the bulkhead pillar side. It may be provided.

A rake device 0 that moves in the circumferential direction is disposed on the outer peripheral side surface of the U-shaped bar screen 5. This is supported by a pedestal 91 disposed on one side of the waterway 1, arranged along the outer circumferential surface of the purse 1, and driven by a drive unit 93 of the pedestal 1. A plurality of rakes 92 are provided at intervals, and the screen residue captured by the bar screen 5 is scraped up by the operation of the rakes 92. The screen residue scraped up by this I/-key is thrown into running water (--carrying means 111 such as a rough conveyor) disposed on one side of the waterway-1, and is carried out to the waterway side for removal.

Note that the operation of the rake device 9 (j is when water is introduced into the waterway,
It is possible to have the train run constantly while dust removal work is being carried out, but it is also possible to have it run periodically.
+J function, and this is done appropriately depending on the amount of contaminants in the waterway, which is 7Ae, and also depending on the change in preference.

〔Effect of the invention〕

In the dust remover of the present invention, a U-shaped bar screen is installed in the center of the waterway, and the wastewater flows into the waterway into the bar screen due to the two functions of the bar screen.
J is the installation number, and the discharge L for discharging filtrated water from inside the bar screen is 3, and 1j is the rake device that moves around the outer circumferential surface of the U-shaped bar screen. , screen residue can be removed efficiently,
Moreover, it has the advantage of being able to miniaturize the device.
