Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1-15, the separating device comprises a cuboid housing, a first filter screen 20 with evenly distributed apertures, a second filter screen 20 with evenly distributed apertures, a first laser sensor 23, a second laser sensor 24, a hydraulic cylinder device, an external ore collecting box, 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 containing bag, a pulverizer ore grain inlet, a pulverizer ore grain outlet, a pulverizer rotating gear 29, a sliding plate 30 meshed with the pulverizer rotating gear 29, a protrusion 31 on the sliding plate, a pulverizer mineral baffle plate 32, the first push plate 7 and the second push plate 8 all have one-way movability.

Specifically, its theory of operation is that the water inlet 5 of water tank links to each other with external suction head, two parts about first filter screen 20 falls into the water tank, open the water pump, external suction head inhales the water tank with the ore granule, because the action of gravity, the ore granule can fall in the position nearer from the water inlet, sea mud then can fall in the position far away from the water inlet, they all fall on the first filter screen 20 that the level was placed, first filter screen 20's aperture is less, make sea mud can enter into the lower part of water tank through first filter screen 20, and the ore granule then can't pass through. The other end of water tank is opened there is delivery port 6, and delivery port 6 is connected with external water pump, and the position of delivery port is equipped with second filter screen 21, and the effect of this second filter screen 21 blocks that aquatic does not can fall the ore grain on first filter screen 20 under the action of gravity, avoids it to get into the water pump along with water, causes the destruction to 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 push 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 particle crushing device is a gear which rotates continuously, and the ore particles 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 pipeline is not blocked because of the small particle size of the mineral particles. When the sea mud below the first filter screen 20 is accumulated to a certain height, the second laser sensor 24 is blocked, the hydraulic cylinder controlled by the second laser sensor 24 starts to work, and the hydraulic cylinder enables the second push plate 8 to push the sea mud to the second door panel. When the second door panel is opened, the outer hook 33 is hooked in the hard handle 27 of the bag 25, the outer hook 33 is driven in the opening process of the second door panel 8, and the opening of the bag is opened by the outer hook 33. The second push plate 8 pushes the sea mud into the bag, after 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, because the handle of the bag is hard, the handle of the next bag naturally hangs down, and the outer hook 33 is embedded into the hard handle 27 of the next bag when the second push plate 8 is closed.

In addition, the joint of the bag and the box is also specially treated, so that the bag automatically falls off after a certain weight of sea mud is collected. Specifically, two small posts extend out of the lower portion of the box, two holes of the bag penetrate into the posts, and a mechanism for clamping the bag is arranged at the lower end of each post, so that the bag cannot easily fall down. Therefore, separation of ore particles, sea mud and water is realized, and a repeatable sea mud collecting mechanism is also realized. Considering that ore particles may pass through the first push plate 7 and fall into a position between the first push plate 7 and the hydraulic cylinder, so that the first push plate 7 cannot be retracted, 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 a cut part is arranged on one surface, in the process of retracting the push plate 1, if the ore particles are touched, the push plate is pushed to be in a state of being in line with the rod because of the blocking of the ore particles, so that the push plate cannot be retracted because the ore particles are blocked by particles, after the push plate returns to the initial position of the rod, due to the action of water flow or the action of the ore particles during secondary working, the stress in the normal direction of the cutting surface is decomposed into a state of being in line with the cutting surface and being perpendicular to the cutting surface, and two component forces can make the first push plate.

When the particulate matter on the filter screen piles up the take the altitude and will block laser, make the receiver unable receipt, trigger the pneumatic cylinder work this moment, make first push pedal 7 stretch out, release the particulate matter, at this moment, the power of the pump of being connected with the water tank delivery port is transferred down, and no longer the high power is inhaled water, and the pump of being connected with the delivery port just resumes normal power work again until first push pedal 7 releases the ore grain. When the particles are pushed to the ore particle outlet, the first door plate is opened, the pump connected with the ore particle outlet of the crushing device starts to work, and the ore particles are sucked to the relay storage for storage; the second laser sensor 24 is located below the first filter screen 20 and above the sea mud outlet, the working principle is the same as that of the first laser sensor 23, when the sea mud is stacked to a certain height, laser emitted from one end of the second laser sensor 23 is blocked, so that a receiver located at the other end cannot receive the laser, 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 the sea mud falls into an opened bag.

The working principle of the ore grain crushing device is as follows: after entering the device, the ore particles slide down along the sliding plate 30, and when meeting the bulge 31, the ore particles contact the gear 29 rotating at high speed, and the gear 29 and the bulge 31 are pressed to crush the ore particles. The baffle 32 is designed to prevent the escape of mineral particles. The crusher ore grain inlet is connected with the water tank ore grain outlet 3 by a bent pipe.
