Abstract
The utility model discloses underwater magnetic separation equipment at the front end of a sand dredger. Magnetic iron minerals in gritting materials underwater can be also recovered by the underwater magnetic separation equipment when a bucket type sand dredger is in sand dredging operation. The equipment is characterized in that an underwater magnetic separation cylinder 11 is arranged at the front end of a loading position of a sand excavation hopper of the bucket type sand dredger; the cylinder rotates along the sand flow direction; and the oblique upper part of the up position of the cylinder is provided with a magnetic induction roller 22 and is also matched with an ore receiving hopper 23, a sand pump 24, and the like. The cylinder is dragged by an underwater train wheel 5, thus the bucket type sand dredger can also recover most magnetic sand in the gritting materials underwater when in sand dredging operation. The magnetic separation cylinder 11 is arranged on a position that the sand flow passes through, therefore, the length and the rotating speed of the magnetic separation cylinder can be increased again so that the large magnetic sand productive rate is achieved.
Description
One, technical field:
The utility model relates to a kind of magnetic plant under water: specifically suitable magnetic plant is placed the bottom of chain bucket dredge front end, adopting the adopting in the sand operation of sand ship, the double magnetic iron-bearing mineral of receiving in the gravel under water of taking back.
Two, background technology:
Current existing chain bucket dredge quite a lot in the river, river and beach sand field operation, remove pure with adopt sand be purpose adopt the sand outboard, the dredging dredge boat is still arranged, select iron adopt the sand ship, pan gold ore out adopt the sand ship, adopt that sand chooses other mineral adopt the sand ship.In the gravel of river sand or sand field, beach, usually all have and contain a certain amount of magnetic iron-bearing mineral, do not obtain paying attention to because iron-holder is on the low side, existing " a kind of magnetic plant under water " patent, (patent No.: 03244270.X), be magnetic pole to be set and to replace to adopt the original sprocket wheel under water of sand ship in adopting the sprocket wheel under water of sand ship with its, though can select a certain amount of iron sand, but it can't obtain to adopt pack into from the dead ahead iron-bearing mineral the bucket gravel of sand ship, and the selective ratio of its river sand is lower.
Three, summary of the invention:
The purpose of this utility model be for chain bucket dredge provide a kind of in adopting the sand operation the double magnetic plant under water of receiving magnetic mineral in the gravel of taking back.It is installed in adopts the dig sand front end of bucket of sand ship, making packs into dig sand the river sand of bucket from magnetic pulley below by, magnetic pulley along the iron sand in revolution of sand flow direction and the absorption gravel; Be adsorbed iron sand and rotate certain altitude with cylinder, at magnetic induction roller place, the effect of being responded to the trapezoidal magnetic field of roller is transferred to gravel induction roller, iron sand is after enclosing with induction roller rotation 1/4, promptly enter the differential gap of induction roller, and lose magnetism, drop down onto in gravity and action of centrifugal force tenesmus and connect ore bucket this moment; Connecing the ore bucket bottom has pipeline to link to each other with Sand pump, and the Sand pump suction connects the river in the sand hopper, and the magnetic mineral that choosing is treated promptly is sucked disembarkation.
Its technical scheme is: it comprises the magnetic pole 21 in magnetic separation roller 11 and the cylinder, also has magnetic induction roller 22, connect ore bucket 23 under water, Sand pump 24, it is characterized in that, selected magnetic separation roller is supported by hinged girder, and hinged girder one end is articulated in the lower end of chain bucket beam 6, and the other end joins with main winch 10 and secondary hoist engine 18 respectively by suspension bracket 13, movable pulley 14, steel wire rope 15, fixed pulley 16,17; Magnetic induction roller 22 places the oblique upper position at cylinder 11 up places; Connect the below that ore bucket is arranged on the magnetic induction roller under water, the bottom has pipeline and Sand pump to join; Establish sand block plate 25 above magnetic separation roller, at the magnetic induction roller, cover cap is established in the top that connects ore bucket under water.
Under water magnetic separation roller and be sealed in the cylinder with the magnetic pole 21 of its reverse rotation by adopt the sand ship under water sprocket drum 5 drag; The direction revolution of magnetic separation roller 11 sand flow when adopting the sand ship and load under water.
The beneficial effects of the utility model are to adopt the front portion installing magnetic pulley that the sand ship loads the bucket of digging sand, it is by the chain wheel drive under water of adopting the sand ship, relend magnetic assist induction roller and other servicing unit, can doublely take back the vignite of receiving in the gravel, reach the mineral resources of comprehensive utilization dispersion and improve the purpose of adopting sand ship economic benefit.
Four, description of drawings:
Fig. 1 is the magnetic plant under water at chain bucket dredge dress sand hopper headend equipment.
Five, the specific embodiment:
Chain bucket dredge shown in Figure 1 and with this under water the relevant facility of magnetic plant comprise: flatboat 1, power set 2, transmission device 3, scoop chain 4 reach sprocket drum 5 under water; Sprocket drum is supported on the lower end of the chain bucket beam 6 that links with gear frame under water, and is linked to each other with hoist engine 10 by pulley 8, steel wire rope 9 by bracing frame 7.Hoist engine is in order to regulating the height of chain bucket beam 6 lower ends, thereby adjusts the height of sprocket wheel 5 and the operation intensity of scoop chain 4 under water.
The magnetic plant under water of adopting the setting of sand ship dress sand hopper front end is the place ahead that magnetic separation roller 11 under water is installed in the bucket loading place of digging sand, it is supported by hinge joint beam 12, hinge joint beam one end links near the lower end of the chain bucket beam 6 the sprocket wheel 5 under water, the other end hang suspension bracket 13 and above movable pulley 14 and the steel wire rope 15 of both sides on; One end of steel wire rope joins through fixed pulley 16 and main winch 10, and the other end links to each other with a pair hoist engine 18 by fixed pulley 17.Fixed pulley 16,17 is supported by strut 19, it with pull bar 20 and ship on bracing frame 7 composition heavy burden truss; Magnetic separation roller and be sealed in magnetic pole 21 in the cylinder under water, by adopt the sand ship under water sprocket drum 5 drag.
Magnetic separation roller 11 is along the rotation of sand flow direction under water, be adsorbed on magnetic mineral on the cylinder be subjected to an interior reverse rotation magnetic pole 21 effect and " magnetic turns over " phenomenon takes place, this can get rid of the non-magnetic particle that is mingled with, magnetic mineral is revolved when bringing to induction roller 22, it is subjected to the effect of intensive induced field and shifts, the magnetic mineral that is transferred to the induction roller is after entering the differential gap, magnetic field with induction roller rotation 1/4 circle, because of losing the attraction in magnetic field, under gravity and action of centrifugal force, and fall in connecing ore bucket 23, connect ore bucket bottom pipeline and Sand pump 24 join (Sand pump also can be installed on ship storehouse or the deck) are arranged, Sand pump suction connects the river in the ore bucket 23, select magnetic mineral also just be sucked disembarkation.
Sand block plate 25 is established on the top of cylinder 11 under water, enters in order to prevent gravel from covering cylinder to connect ore bucket 23; Magnetic induction roller 22 and connect ore bucket 23 tops cover cap 26 is set, the silt particle that is used to block suspension enter and connect ore bucket and influence the iron sand quality.
Main winch 10 can synchronization liftings sprocket wheel 5 and magnetic separation roller 11 under water under water; Magnetic separation roller can also be regulated high and low position on demand by paying hoist engine 18 under water.
