Detailed Description
The invention will be further described with reference to the drawings and specific examples.
Referring to fig. 1 to 15, the separating apparatus includes a rectangular parallelepiped housing, a first filter screen 20 having an evenly distributed aperture, a second filter screen 20 having an evenly distributed aperture, a first laser sensor 23, a second laser sensor 24, a hydraulic cylinder device, an external mineral collecting tank, a first push plate 7, a second push plate 8, a first door plate, a second door plate, an external water pump, a rotatable hook, a sea mud flexible container, a pulverizer mineral grain inlet, a pulverizer mineral grain outlet, a pulverizer rotating gear 29, a slide plate 30 engaged with the pulverizer rotating gear 29, a protrusion 31 on the slide plate, a pulverizer mineral baffle 32, the first push plate 7, and the second push plate 8 all have unidirectional mobility.
Specifically, the water inlet 5 of the water tank is connected with the external suction head, the water tank is divided into an upper part and a lower part by the first filter screen 20, the water pump is turned on, ore particles are sucked into the water tank by the external suction head, the ore particles can fall at a position close to the water inlet due to the action of gravity, sea mud can fall at a position far away from the water inlet, the sea mud falls on the first filter screen 20 which is horizontally arranged, the aperture of the first filter screen 20 is smaller, and the sea mud can enter the lower part of the water tank through the first filter screen 20, but the ore particles cannot pass through the lower part of the water tank. The other end of the water tank is provided with a water outlet 6, the water outlet 6 is connected with an external water pump, a second filter screen 21 is arranged at the position of the water outlet, and the second filter screen 21 is used for blocking ore particles which cannot fall on the first filter screen 20 under the action of gravity in water, so that the ore particles are prevented from entering the water pump along with the water and damaging the water pump. When the ore particles on the first filter screen 20 reach a certain height, the laser emitted by the first laser sensor 23 is blocked, the hydraulic cylinder controlled by the first laser sensor 23 starts to work, the hydraulic cylinder enables the first pushing plate 7 to push the ore particles to the first door plate, the first door plate is opened, the ore particles reach the ore particle crushing device 26 below the outlet, and meanwhile, the first door plate is closed; the main part of the ore grain crushing device is a continuously rotating gear, so that the ore grains can be crushed into small particles under the action of extrusion force; the crushed ore particles are sucked into a relay bin by a pump connected with an ore particle outlet of the crushing device and stored. In this process, the pipe is not blocked due to the small size of the ore particles. When sea mud below the first filter screen 20 is accumulated to a certain height, the second laser sensor 24 is blocked, and a hydraulic cylinder controlled by the second laser sensor 24 starts to work, and the hydraulic cylinder enables the second pushing plate 8 to push the sea mud to the second door plate. At this time, the second door panel is opened, the outer hook 33 is hooked in the hard handle 27 of the bag 25, and the second door panel 8 drives the outer hook 33 during the opening process, and the outer hook 33 opens the mouth of the bag. The second push plate 8 pushes sea mud into the bag, when the sea mud amount in the bag reaches a certain weight, the bag falls off under the action of gravity and slowly falls onto the seabed, the handle of the next bag naturally sags due to the fact that the handle of the bag is hard, and the outer hooks 33 are embedded into the hard handle 27 of the next bag when the second door plate 8 is closed. In order to smoothly finish the process of filling the bags with sea mud, the bags are specially treated, a trapezoid table is designed at the inlet of each bag, so that sea mud filled into the bags cannot easily fall out from the bag, handles of the bags are hard, each handle of the bag placed at the bottommost part naturally sags under the action of gravity, so that the next hook is conveniently hooked, and the continuity of a bagging mechanism of the bags is realized. In addition, special treatment is carried out on the connection part of the bag and the box, so that the bag automatically falls off after a certain weight of sea mud is collected. Specifically, stretch out two little posts in the lower part of case, penetrate the post with two holes of sack, the post lower extreme has the mechanism that is used for blocking the sack for the sack can not fall down easily. Thus, the separation of ore particles, sea mud and water is realized, and a repeatable sea mud collecting mechanism is also realized. Considering that ore particles possibly pass through the first push plate 7 and fall into a position between the first push plate 7 and the hydraulic cylinder, the first push plate 7 cannot be retracted, for this purpose, the push plate is designed into a special shape, namely, the edge structure of the first push plate 7 is designed into a special cutting shape, namely, one side of the first push plate is provided with a cut part, if the ore particles are hit against the push plate 1 in the retraction process of the push plate, the push plate can be pushed to be in a state of being in line with a rod piece because of the blocking of the ore particles, the ore particles can be prevented from being blocked by the particle materials and cannot be retracted, after the initial position of the rod piece is returned, the normal force of the cutting surface can be decomposed into a state along the cutting surface and a state perpendicular to the cutting surface due to the action of the water flow or the ore particles during the re-working, and the two component forces can enable the first push plate 7 to be restored to be in line with the rod piece.
The specific working principle of the sensor system is as follows: the first laser sensor 23 is arranged at the lower end of the water inlet and at the upper end of the ore grain outlet; one end of the laser sensor emits laser light, and the other end receives the laser light. When the particulate matters on the filter screen are accumulated to a certain height, the laser is blocked, so that the receiver cannot receive the particulate matters, the hydraulic cylinder is triggered to work at the moment, the first push plate 7 stretches out to push out the particulate matters, at the moment, the power of the pump connected with the water outlet of the water tank is regulated down, the high-power water absorption is stopped, and the pump connected with the water outlet is restored to normal power work until the first push plate 7 pushes out the mineral grains. When the particles are pushed to the ore particle outlet, the first door plate is opened, and a pump connected with the ore particle outlet of the crushing device starts to work to suck the ore particles to a relay storage for storage; the second laser sensor 24 is located below the first filter screen 20, above the sea mud outlet, and the working principle is the same as that of the first laser sensor 23, when sea mud is accumulated to a certain height, the laser emitted by one end of the second laser sensor 23 is blocked, so that the receiver at the other end cannot receive the laser, at this time, the hydraulic cylinder starts to work, the second push plate 8 is pushed out, the sea mud is slowly pushed to the sea mud outlet, and falls into the opened bag.
The working principle of the ore grain crushing device is as follows: the ore particles slide down the slide 30 after entering the device and contact the gear 29 rotating at high speed when encountering the protrusion 31, the gear 29 and the protrusion 31 pressing to crush the ore particles. The shield 32 is designed to prevent the escape of ore particles. The ore grain inlet of the pulverizer is connected with the ore grain outlet 3 of the water tank through a bent pipe.
The invention designs a mineral/sea mud separating water tank of a submarine ore collecting system, which is more reasonable, efficient and environment-friendly for treating the collected mixture of mineral particles and sea mud. The following improvements are proposed for this purpose: the water tank is specially designed, has a firm and corrosion-resistant external structure, and is suitable for being exposed to the seabed for a long time. The design conforming to fluid mechanics is adopted inside, the fluid flow resistance is reduced, so that the flow velocity in the box body is maximized, and the separation efficiency is ensured. Meanwhile, the water tank adopts an effective control technology, and the filling condition of the water tank is automatically judged by using a sensor, so that automatic control is realized; meanwhile, a special structural design is adopted, the separated sea mud is filled into a degradable bag, and the sea mud in the bag sinks into the sea floor after reaching a certain weight. This approach can greatly reduce damage to the subsea environment. Compared with a common filtering water tank, the invention can effectively separate ore particles, sea mud and water, realize automatic control, crush the ore particles and is friendly to the seabed environment.
The foregoing is a preferred embodiment of the present invention, and various changes and modifications may be made therein by those skilled in the art without departing from the general inventive concept, and such changes and modifications should be considered as falling within the scope of the claimed invention.
