Description

Dredging treatment device equipped with rotary tilt hopper {SEDIMENT TREATING APPARATUS HAVING RORARY TILT HOPPER}

The present invention relates to a dredge treatment apparatus equipped with a rotary tilt hopper, and more particularly, dredged to separate and clean the dredged sediment deposited on the bottom of the river or sewage within the treatment criteria to recycle into construction materials or cover, etc. In the processing apparatus, dredged water input from dredging vehicle is temporarily stored in the hopper and then supplied to the screen device by a certain amount, thereby preventing excessive load on the subsequent mechanical device, and debris and sludge formed at the top of the screen. The present invention relates to a dredge treatment apparatus having a rotary tilt hopper that does not accumulate.

In general, dredging refers to an operation of digging deeply into the bottom of a river or sewer by removing soil or rocks stacked on the bottom of a river, a shore, or a sewer.

In addition, soil or contaminants generated by such dredging operations are commonly referred to as "dredging".

When soil or sediment accumulates in a river or sewer for a certain period of time, the depth of the river or sewer becomes shallower and causes environmental pollution.

In order to prevent this, dredging works regularly remove soil or dirt accumulated on the ground of rivers and sewers.

Sediments on the coastal and sewage floors are contaminated with various pollutants generated in natural ecosystems, pollutants flowing from tributaries and streams.

Such contaminated soils and contaminated sediments of rivers, coasts and water and sewage cause water pollution. In particular, contaminated sediments located at the bottom of rivers or lakes, which are water sources, may have serious adverse effects on the human body.

As a result, developed countries have already dredged contaminated soil in rivers for a long time, and dredging works have been carried out on rivers and lakes in Korea.

However, in the past, there is no special way to treat dredged water generated by such dredging operations, and it has been dumped on the ocean.

However, since sewage dredging has been classified as an industrial dumping industrial waste in recent years, the disposal of marine dumping has been legally prohibited, and therefore, treatment of such dredging has emerged as an important task.

Currently, a dust treatment apparatus for separating impurities such as gravel or desorbing organic matter from sand is used for sand cleaning or waste water treatment, but such a treatment apparatus cannot process dredged water.

This is because dredged water contains coarse contaminants, such as rocks and trees, that cannot be processed by conventional contaminant treatment devices.

In order to solve the above problems, the applicant has filed a patent for "Dredged Water Treatment System" and registered as Patent No. 10-0912058.

As described above, the conventional dredged water treatment system, as shown in FIG. 20, a non-spindle screw conveyor 30 for transporting dredged water flowing into the inflow tank 20, a cleaning separation drum screen 40 for cleaning and separating dredged water introduced through the non-screwed screw conveyor 30 Including a fine material conveying conveyor 50 for transporting the fine contaminants filtered by the cleaning separation drum screen 40 to the carrying out container 2, and a settling scrubber 70 for cleaning the sand passed through the cleaning separation drum screen 40 Consists of.

In addition, the above-mentioned dredged water treatment system, the sewage treatment pump 64 for transferring the sand passing through the washing separation drum screen 40 to the sedimentation scrubber 70, the treated water discharged from the sedimentation scrubber 70 sewage treatment plant It includes a treatment water transfer pump 84, the washing separation drum screen 40 and the sedimentation feet 60 to be transferred to the water tank 90 and the pump 92 for supplying the washing water.

According to the above configuration, the dredged water loaded on the dredging vehicle 1 and dropped onto the rough wood screen 10 is introduced into the inflow tank 20 after the coarse contaminant is filtered while passing through the rough wood screen 10. .

The rough screen 10, as shown in Figure 2, is made of a lattice structure, each lattice is manufactured to a size such that coarse contaminants can not pass.

The fine dredged water from which coarse contaminants have been removed while passing through the jaw screen 10 is introduced into the inflow tank 20, and is cleaned and separated by a spindleless conveyor with a screwless conveyor 30 fixed to the inner bottom of the inflow tank 20. Are transferred to 40.

The washing separation drum screen 40, while being driven to rotate to clean the dredged water by the washing water supplied from the water tank 90 to separate the sand and water.

The cleaning separation drum screen 40 is installed to have an inclination of approximately 10 degrees, and if dredged water is introduced into the drum by the non-screw screw conveyor 30, the perforations cannot be passed through the screw blades mounted on the rotating drum. Allow dredged water to drain out.

The fine dredged material, such as gravel, which is separated and discharged to the discharge port of the drum without passing through the perforations in the cleaning separation drum screen 40, is transferred to the unloading container 2 by the contaminant unloading conveyor 50.

Then, the water and sand discharged from the cleaning separation drum screen 40 are transferred to the sedimentation pit 60, and then transferred to the sedimentary scrubber 70 for washing the sand by the sedimentation transfer pump 64.

The sedimentation pit 60 is provided with a level sensor 62 for detecting the level of water flowing from the cleaning separation drum screen 40, and the water and sand flowing into the sedimentation pit 60 to the immersion cleaner 70. An acupuncture transfer pump 64 for transferring is installed.

By the above structure, the water and sand discharged through the perforations from the cleaning separation drum screen 40 flows into the immersion pit 60, and the water and sand levels detected by the level sensor 62 are at the set level. Upon reaching, the sedimentation transfer pump 64 is operated to transfer the water and sand introduced into the immersion pit 60 to the immersion scrubber 70.

The sewage transferred by the sedimentation transfer pump 64 is separated into sand and organic matter in the sedimentation scrubber 70, and the separated sand is washed and carried out to the outside.

The sedimentation scrubber 70 is a device that separates sand and organic matter and cleans the separated sand. The sedimentary scrubber 70 is connected to the sedimentation pump 64 to inflow through the inlet 72 and the inlet 72 for transporting sewage. It consists of a cleaning tank 74 in which the sewage is washed and separated, and a sand conveying part 79 in which the washed and separated sand is carried out to the outside.

The cleaning tank 74 separates sand and organic matter from the sewage flowing through the inlet 72 and cleans the sand.

The sand separated and washed in the washing tank 74 and precipitated at the lower end of the washing tank 74 is carried out to the outside through the sand transfer unit 79 connected to the lower end of the washing tank 74.

The sand conveying unit 79 is composed of a spindle screw conveyor for transporting sand and a conveyor pipe surrounding the spindle screw conveyor.

Then, the treated water overflowed from the immersion scrubber 70 is discharged through the discharge port 73 of the immersion scrubber 70 and moved to the treated water pit 80, and then the sewage treatment plant by the treated water transfer pump 84. Is transferred to.

The treated water pit 80 is provided with a level sensor 82 for detecting the water level of the treated water flowing from the sedimentation scrubber 70, and transfers the treated water flowing into the treated water pit 80 to the sewage treatment plant. A water transfer pump 84 is installed.

The treated water overflowed from the immersion scrubber 70 and discharged flows into the treated water pit 80, and when the level of the treated water detected by the level sensor 82 reaches a set level, the treated water transfer pump ( 84 is operated to transfer the treated water introduced into the treated water pit 80 to the sewage treatment plant.

In the conventional dredged water treatment system, dredged water containing coarse contaminants can be separated and cleaned within a treatment time within a short time through a series of continuous processes, and the treated dredged material is recycled as construction materials or cover. You can do it.

However, as a result of actually operating the dredged water treatment system described above, the following problems were found.

First, in the conventional dredged water treatment system, it is difficult to supply a dredged water in a constant amount to a treatment apparatus.

In the conventional dredged water treatment apparatus, as shown in FIG. 1, the dredged water is dropped from the dredging vehicle 1 directly to the roughing screen 10.

As a result, dredged water poured in a row may be excessively supplied to the screw conveyor 30 and the cleaning separation drum screen 40 which are subsequent processes.

If dredged water is in excess of the processing capacity of subsequent machinery, the load suddenly increases, adversely affecting the machinery and causing failures.

Second, the conventional method should periodically remove the impurities and sludge accumulated on the wood screen.

As shown in FIG. 2, the conventional rough screen 10 is fixed to the upper portion of the inflow tank 20 as a lattice-shaped plate structure.

As a result, sludge from dredging spilled over into the lattice is accumulated in the form of acid on the wood screen along with the contaminants on the lattice.

In this way, when the contaminants and sludge accumulate on the crude wood screen, the operation of the treatment device must be stopped and the operator manually removes them using a high pressure cleaner.

This causes a problem that the dredging processing time is delayed and the management cost of the treatment apparatus is increased.
