Description

A kind of beach placer ore dressing ship

Technical field

The utility model belongs to mine ore dressing technical field, the Mineral Dressing Process that exploitation utilizes for beach placer especially.

Background technology

The many coastal state's along the coastlines in the world have a large amount of iron ore deposits, develop beach placer resource, the artificial shovel of original adoption digs elutriation, conventional is the simple and crude ore dressing ship with fishing boat or small-sized bullk reform now, directly screening and preparation equipment are erected on fishing boat, although this way investment economizes, but production capacity and production efficiency are extremely low, production operation condition is poor, the transportation problem, confession distribution problem, overhaul of the equipments problem, the problem concerning life that are difficult to solve a large amount of ore pulps, this way is difficult to realize extensive mineral processing production.Especially in the area that there is no externally fed condition, outside land transport condition, production technology feasibility is less.

The raw ore slurry that mining dredger hinge drinks up generally contains the foreign material such as great Liang Zuo grass, tree root, if do not separated before entering ore-dressing technique, certainly will greatly affect ore dressing effect, after separating also will be got rid of outside hull in time, otherwise cause accumulation, in research process, carry out the selection of several screening modes and marker method, effect is not clearly, finally attempted belt feeder discharge, allow foreign material waste residue have compass screen surface to turn and be discharged to belt feeder, by belt feeder, be transported to stern and dump ashore, do not affect the clean of mining lake lake surface.

Mining area, most beach is far away apart from city, lacks external power source, and some ore deposits are placed on generating equipment on the bank, and electric power is by cable transfer to ore dressing ship, and because ore dressing ship is mobile, transmission distance changes, and electric power is carried both inconvenient, and power consumption is also large.If placed aboard ship, electricity generation system (comprising generating set, boiler unit, air compressor plant, cooler, emergent unit, fuel oil supply unit, transformer, oil tank etc.) weight of equipment and take up room larger, in the limited space of hull, arrange more difficultly, need to solve hull draft problem, gravity balance problem, hull stable problem, space Layout Problem.If the overweight drinking water of hull is too dark, hull is easily stranded; If each forms module, put bias, hull easily topples; The beach stormy waves of holding concurrently is larger, and hull is too high, is subject to stormy waves and threatens.Overcome the above problems; so all wts such as equipment, material, pipeline will be carried out to three-dimensional planning; Spatial Coupling distributes; upper lower leaf, front and back subdivision, by functional module, divide and distribute usage space, making hull center of gravity occupy hull center, compressing hull height and space size as far as possible; allow hull meet production and application requirement; have and can accomplish that hull space minimizes, function is distributed rationalization, uses safe, energy-conserving and environment-protective.

Be used at present the simple and easy ore dressing ship of production and there is no indoor office recreating facility and dining room, dining room, while running into wind and rain, direct labor hides nowhere, work under bad environment, operate dangerous, run into severe weather conditions and want breaks in production, the utility model comprehensive division hull usage space, make full use of hold as dining room, dining room, utilize the space of top layer deck boiler unit side as office lobby, multideck and surrounding enclosed structure are that hull forms enclosure space, have improved work production environment, have improved production efficiency.

Summary of the invention

The purpose of this utility model overcomes the weak point of existing simple and crude ore dressing ship, provide a kind of Process configuration compact and reasonable, easy to operate, equipment moving flexibly, investment saves, operating cost is low, beneficiating efficiency is high, sorting result is good, the most applicable to beach placer body, can realize the complete exploitation of beach placer body, do not waste resource, guarantee making full use of beach placer resource; Can recover rapidly landforms, protected to greatest extent natural environment simultaneously.

The technical scheme that realizes foregoing invention comprises: Ship Structure, ore-dressing technique system, electricity generation system, distribution and control system, material (comprising former ore in sand form, rough concentrate, slag, mine tailing, water) induction system, office life and affiliated facility etc.

Owing to having adopted technique scheme, compared with prior art the utility model has the following advantages:

1. technology arrangement is flexible, equipment configuration is compact, save space, security of operation is stable, easy to operate;

2. occupation of land is little, saves the energy, and environmental protection condition is good, and work situation is good;

3. effectively improve technique and working condition;

4. slag and mine tailing directly enter behind mining lake, recover former sandy beach, eliminate environmental pollution;

5. handling safety.
