Description

MARINE SAND COLLECTING AND DROPPING DEVICE}

The present invention relates to an offshore sand-dripping loading device, and more particularly, to directly load the dredged soil dredged using a submersible pump in a dredger to directly ship the sand produced to an anchored bulk carrier.

At present, Korea has been running out of aggregates in most rivers except for some local rivers. Therefore, sand and dredged soils, reclaimed land and paddy fields and fields have been selected and washed. have.

However, since the dredged soils collected as described above have a high content of soil, it is not easy to sort and collect sand from dredged soils at once, which requires a lot of equipment and manpower and increases the burden of going through a complicated process.

For example, referring to the conventional process of producing sand from dredged soil, as shown in Figure 1, the dredger 10 dredged the dredged soil with the water by dredging aggregates buried in the bottom of the water using an underwater pump After loading and transported to the land, the sand and gravel are first separated from the land sorter 20, and discharged to the ground with water, the discharged sand is transferred to the excavator (30) by the excavator 30 The sand is subsequently introduced into the regular washing machine 40.

Then, after washing repeatedly for a second time in order to wash the salt and soil contained in the selected sand introduced from the regular washing machine 40, the sand (S2) that has been washed through the conveyor (50) to the ground Will be loaded.

As such, in the related art, the process of selecting and washing sand in dredged soil uses separate equipment, and thus, the process is complicated and requires a lot of work time, and between the land separator 20 and the pure water washer 40. There was an uneconomical problem due to the excessive input of equipment and manpower, such as to transport sand using the loading and transport equipment such as the excavator 30 and the conveyor 50.

Moreover, there have been many problems such as the need for a shipping facility and a shipping dock again when attempting to transport the ship through the sea or to ship to an export vessel.

Accordingly, the present applicant has filed a utility model registration application 99-11012 'sand screening washer' on June 21, 1999 to sort out sand from dredged soil and to wash the selected sand as a solution to solve this problem. The above-listed sand screening washer can sort the sand at the same time as dredged soil and at the same time wash the screened sand, but because the produced sand can not be shipped directly to the bulk carrier directly, There is a need for a separate yard and the like, when using the sand accumulated in the yard, such as having to carry again by using a vehicle and transport equipment, such as an excavator.

Therefore, the present invention is to solve the above-mentioned problems, the economical sand production by directly loading the dredged soil dredged by using a submersible pump in the dredger can be shipped directly to the anchoring bulk carrier ship The sand sanding loading system can greatly reduce sand production costs by not only increasing productivity in sand production by drastically shortening work processes and time due to the structure, but also reducing equipment and oil costs and manpower input. The purpose is to provide.
