Ｃある。Conventionally, the ore collecting device for Iζ mankan nodules has been considered to be J
This is a device that collects the nodules that are half exposed in the silt using a pump, or blows them away with a stream of water. Emphasis was placed on the development of clayey silt (all of which was buried), and these devices collected what was exposed on the surface of the silt. The collection of nodules had the disadvantage of not being able to bottom out.Next, in order to compensate for this shortcoming, the nodules were dug up along with silt by a forward rotating hoe. A device that collects ore by sucking in nodules along with silt.
(And 0, set up a field in the ore collector (J) to dig up the nodules together with silt, and blow them away with a jet stream of water. This device uses auxiliary means such as a hoe or spade (one step is to dig up a nodule that is about 10 cm buried and collect the ore directly, so a large clay lump is collected together with a mannoan nodule and the ore is lifted. Therefore, it is extremely uneconomical.

め、抹Ｍ１に要りる」ニネルギーは増入りる。The ratio between mankan nodules and clay lumps (the difference in specific gravity is small) is difficult to mine. Therefore, once the manganese nodules are collected together with the clay lumps, the clay lumps and manganese nodules are placed in seawater using a separate Ill Jl' 3B &n.
Stir and dissolve the clay in seawater to 1lta mud (4°C).
If the ore beneficiation equipment was used, there would be problems such as breakdowns (decreased safety factor), and even small nodules would become smaller. 10 is a big loss because it is removed. Also, 1 concession)] If it is reduced by 11, clay lumps of various sizes of 1B and 1B will be added to the manganese nodules. Since there is no such thing, it is necessary for M1 to increase in energy.

われる。The configuration of this device will become clear from the description related to the operation of the present device described below. The excavation of the mankan nodules is carried out by using high pressure water from the injection pump 7 and high pressure water flow pipe 24, and the branching color and the position of the excavation concentrator 10 facing the seabed. By injecting toward the C silt, the silt (clay) is reduced to 5.~1Qc.
This is carried out by crushing the seabed surface 40 between the top plate 355 of the excavation concentrator 10 and turning it into thick mud water with stirring.

A particle size of about icm is passed through the suction port 22 provided in the rift, through the r-sitter 36, and through the gap 1. between the seabed surface 40 and the top plate 35.
The thick muddy water discharge pipe 21 is sucked together with the seawater entering from s +.
more discharged and removed. During these 4 tons, the percentage of seawater gold mud in the excavation concentrator 10 is constantly reduced and the ore is beneficent, so that the efficiency of excavating manganese nodules can be improved.

でおる。In addition, a suction pump may be used as a means for the C1 suction beneficiation in the excavation ore beneficiation section 10, but since the muddy water and clay handprint are sucked into a ceiling suspension, it is necessary to take into account low efficiency and failure due to wear and the like. In this embodiment, as described above, the injection pump 7 is used to connect the high-pressure water flow pipe 27 for suction of the thick mud water discharge pipe 21.
The structure is such that seawater is pumped at high speed at a rate of 1rJ from a nozzle 26 provided at the tip of the nozzle 26. As a result, a strong negative pressure is generated at the suction port 22 of the moist water discharge @ 21, and unnecessary excavation and pulverization are carried out through the filter 336.
Oni and small nodules oni/l muddy water comes from the rear of the water device.
Only the necessary nodules are exposed on the ocean floor. This J is C1IiI, which discharges and sucks so-called muddy water and simultaneously crushes the silt with a jet jet of high-pressure water! The cutting efficiency is high.

J: A lattice plate 31 is provided to prevent the ore collecting pipe 30 from clogging. This lattice plate 31 prevents extra-large ore lumps from being sucked into the suction port, and when the ore collecting section moves forward, they are pulled away from the suction l and left in the Shangmu, so that only the required ore lumps are sucked in and collected. In this way, the manganese nodules collected by suction are collected by the suction pump 61 connected to the ore collecting pipe 330. s

。As mentioned above, this defense includes an excavation ore processing section and an ore collection section,
When the silt on the seabed is crushed and excavated by a water jet, it is agitated at once, exposing the buried nodules in the thick muddy water, and sucking up unnecessary thick muddy water and small lumps of clay contained therein into the excavation area. [The nodules exposed during the ore beneficiation are collected through the ore collecting pipe (J), which contains a large amount of clay, unlike conventional equipment. There is no need to collect nodules together with thick mud water, there is less reduction in ore collection efficiency and breakdowns due to suction pump wear, and there is no need for ore beneficiation after ore collection. Since clay lumps are not pulled up, this method has the advantage of reducing the energy loss required for lifting ore.
