Description

Technical Field

[0001] The invention relates to the technical field of marine engineering, in particular to a seawater separation device. Background Art

[0002] Due to the influence of human activities, many metal products enter the ocean, causing pollution to the marine environment. Most of these metal products will enter the seabed or shallows and mix with mud and sand particles. If these metal products are not salvaged and cleaned up in time, they will have a significant impact on the marine ecological environment. At the same time, some metals such as iron, cobalt, nickel and other ferromagnetic metals are widely used in various fields such as production, life, national defense science and technology due to their ferromagnetism at room temperature, and have great recycling value.

[0003] Before recovering metals in seawater, it is necessary to first filter out the silt particles in the seawater and then separate the metals from the silt particles. However, the traditional sedimentation method has a slow filtration speed, and it is not easy to remove the solids from the filter tank during filtration, causing the solids to accumulate on the filter screen for a long time, further reducing the speed of solid-liquid separation. During magnetic separation, the silt particles tend to accumulate in one place, resulting in a relatively poor separation effect. Therefore, a seawater separation device is proposed to solve the problem of ferromagnetic metal separation efficiency in seawater. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a seawater separation device in view of the deficiencies in the above-mentioned prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a seawater separation device, including a box body, a solid-liquid separation mechanism is provided inside the box body, a metal separation mechanism is provided on the right side of the box body, and a metal collecting mechanism is provided on the surface of the metal separation mechanism; the solid-liquid separation mechanism sends mud and sand particles in the seawater into the metal separation mechanism at preset time intervals and drives the metal separation mechanism to rotate, the solid-liquid separation mechanism transports seawater to the metal separation mechanism at preset time intervals, and the metal separation mechanism separates magnetic metals in the seawater and transports them to the metal collecting mechanism.

[0006] In this technical solution, the box body is tilted to the left at a certain angle, so that seawater is not easy to enter the metal separation mechanism. At the same time, the seawater in the box body is tilted to the left due to gravity, so that the solid-liquid separation effect is better.

[0007] Preferably, a liquid inlet regulating mechanism is provided inside the box body, a transverse plate is welded to the inner wall of the box body, and a water outlet is provided on the surface of the transverse plate.

[0008] In the present technical solution, by setting up a liquid inlet regulating mechanism, the water inlet condition in the solid-liquid separation mechanism can be adjusted, and the intermittent water inlet of the solid-liquid separation mechanism can be coordinated to avoid unseparated seawater from passing through the solid-liquid separation mechanism, thereby improving the efficiency of solid-liquid separation. By setting up a water outlet, the separated seawater can be discharged in time, thereby improving the speed of solid-liquid separation.

[0010] In the present technical solution, the size of the water inlet baffle is larger than that of the water inlet, so that the water inlet can be completely covered. The water inlet baffle is located inside the vertical plate, so that the entry of water can be better controlled. By setting up a beating device, the solid-liquid separation mechanism can be beat to vibrate the solid-liquid separation mechanism, thereby better allowing the mud and sand particles on the solid-liquid separation mechanism to fall into the metal separation mechanism, thereby improving the efficiency of solid-liquid separation and also effectively avoiding the blockage of the solid-liquid separation mechanism.

[0012] In the present technical solution, the output end of the motor can rotate alternately forward and reverse, thereby driving the first rotating rod to rotate forward and reverse, and then allowing the filter plate to move back and forth to send the mud and sand particles into the metal separation mechanism. The filter plate is slidably connected to the box body, which can limit the circular motion of the filter plate, and then when the first threaded rod rotates, the filter plate can move on its surface.

[0013] Preferably, the beating device includes a rotating shaft, the surface of the rotating shaft is rotatably connected to the inner wall of the vertical plate, a second gear is welded to the rear of the rotating shaft, and a beating plate is welded to the surface of the rotating shaft.

[0014] In the technical solution, by providing a beating plate, the filter plate can be beaten, thereby knocking down the silt particles on the filter plate, so that the silt particles can be better separated.

[0016] In this technical solution, the magnet is arranged inside the conveyor belt of the belt conveyor, so that the ferromagnetic metal can be adsorbed on the surface of the conveyor belt. Through the uninterrupted operation of the belt conveyor, the ferromagnetic metal can be effectively prevented from accumulating in one place, thereby affecting the adsorption effect of the conveyor belt on the metal.

[0017] Preferably, a feed plate is welded to the inner wall of the base, the right side of the feed plate is welded to the right side of the box, a discharge plate is welded to the lower surface of the feed plate, a return spring is welded to the lower surface of the discharge plate, a support plate is welded to the lower surface of the return spring, and the surface of the support plate is welded and fixed to the inner wall of the base.

[0018] In this technical solution, the reset spring has a certain elasticity, which can enable the discharge plate to move downward in time after moving upward for reset. Both the feed plate and the discharge plate are tilted to the right at a certain angle, and the inclination angle of the feed plate is greater than the inclination angle of the discharge plate, so that the mud and sand particles can better enter the discharge plate.

[0020] In the present technical solution, by setting a special-shaped plate, an upward impact force can be applied to the discharge plate, causing the discharge plate to vibrate, thereby causing the mud and sand particles on the discharge plate to vibrate or jump greatly, so that the metal in the mud and sand particles can better contact with the belt conveyor, and at the same time, it also avoids the accumulation of mud and sand particles on the discharge plate, thereby greatly improving the efficiency of metal separation. The number of second rotating rods is two, and the two second rotating rods are connected by a belt drive, and can thus rotate synchronously.

This seawater separation device can effectively separate solids and liquids in seawater by setting a solid-liquid separation mechanism, and promptly send the separated solids to the metal separation mechanism, thereby avoiding the sediment particles from accumulating for too long, thereby affecting the filtration speed. Through the cooperation of various mechanisms in the metal separation mechanism, the sediment particles can vibrate or even jump greatly, thereby preventing the sediment particles from piling up together, which is beneficial to the separation of metals in the sediment particles.

[0025] 2. This seawater separation device can adjust the water inlet conditions in the solid-liquid separation mechanism by setting a liquid inlet regulating mechanism, and cooperate with the intermittent water inlet of the solid-liquid separation mechanism to avoid unseparated seawater passing through the solid-liquid separation mechanism, thereby improving the efficiency of solid-liquid separation.

[0026] 3. This seawater separation device can beat the filter plate in the solid-liquid separation mechanism by setting a beating device, so that the filter plate vibrates, thereby better allowing the mud and sand particles on the filter plate to fall into the metal separation mechanism, thereby improving the efficiency of solid-liquid separation and also effectively avoiding the clogging of the filter plate.

[0027] 4.

[0041] The box body 1 is tilted to the left at a certain angle, so that it is not easy for seawater to enter the metal separation mechanism 4. At the same time, the seawater in the box body 1 is tilted to the left due to the effect of gravity, so that the solid-liquid separation effect is better. The seawater separation device, by setting the solid-liquid separation mechanism 3, can effectively separate the solid and liquid in the seawater, and timely send the separated solid to the metal separation mechanism 4, thereby avoiding the accumulation of sediment particles for too long, thereby affecting the filtration speed. Through the cooperation of various mechanisms in the metal separation mechanism 4, the sediment particles vibrate or even jump significantly, so that the sediment particles will not accumulate together, which is beneficial to the separation of metals in the sediment particles. By setting the metal collection mechanism 5, the metal in the metal separation mechanism 4 can be collected in time, thereby avoiding excessive accumulation of metal in the metal separation mechanism 4, affecting the efficiency of metal separation.

[0042] In this embodiment, a liquid inlet regulating mechanism 2 is provided inside the box body 1 , a transverse plate 6 is welded to the inner wall of the box body 1 , and a water outlet 7 is provided on the surface of the transverse plate 6 .

By providing the water outlet 7, the separated seawater can be discharged in time, thereby improving the speed of solid-liquid separation.

[0044] Furthermore, the liquid inlet regulating mechanism 2 includes a vertical plate 21, the surface of the vertical plate 21 is welded and fixed to the inner wall of the box body 1, a water inlet 22 is opened on the surface of the vertical plate 21, a support rod 23 is welded to the inner wall of the vertical plate 21, the surface of the support rod 23 is rotatably connected to the first gear 24, the surface of the first gear 24 is welded to the water inlet baffle 25, and the surface of the vertical plate 21 is provided with a flapping device 26.

[0045] The size of the water inlet baffle 25 is larger than that of the water inlet 22, so that the water inlet 22 can be completely covered. The water inlet baffle 25 is located inside the vertical plate 21, so that the entry of water flow can be better controlled. By setting up the beating device 26, the solid-liquid separation mechanism 3 can be beat to make the solid-liquid separation mechanism 3 vibrate, thereby better making the mud and sand particles on the solid-liquid separation mechanism 3 fall into the metal separation mechanism 4, thereby improving the efficiency of solid-liquid separation, and also well avoiding the blockage of the solid-liquid separation mechanism 3.

[0046] The solid-liquid separation mechanism 3 includes a motor 31, the surface of the motor 31 is fixedly installed on the inner wall of the box body 1, and a first rotating rod 32 is fixedly installed on the output end of the motor 31. A worm 33 is welded on the surface of the first rotating rod 32, and a worm wheel 34 is meshed on the surface of the worm 33. A first threaded rod 35 is welded inside the worm wheel 34. A filter plate 36 is threadedly connected to the surface of the first threaded rod 35. The surface of the filter plate 36 is slidably connected to the inner wall of the box body 1, and a tooth plate 37 is welded to the rear of the filter plate 36.

[0047] The output end of the motor 31 can rotate alternately forward and reverse, thereby driving the first rotating rod 32 to rotate forward and reverse, and then allowing the filter plate 36 to move back and forth to send the mud and sand particles into the metal separation mechanism 4. The filter plate 36 is slidably connected to the box body 1, which can limit the circular motion of the filter plate 36, and then when the first threaded rod 35 rotates, the filter plate 36 can move on its surface.

[0048] The beating device 26 includes a rotating shaft 261, the surface of which is rotatably connected to the inner wall of the vertical plate 21, a second gear 262 is welded to the rear of the rotating shaft 261, and a beating plate 263 is welded to the surface of the rotating shaft 261. By setting the beating plate 263, the filter plate 36 can be beaten, and then the mud and sand particles on the filter plate 36 can be knocked off, so that the mud and sand particles can be better separated.

[0049] Example 2

[0050] like Figure 2 , Figure 5-Figure 7 As shown, on the basis of Example 1, in this embodiment, the metal separation mechanism 4 includes a base 41, the left side of the base 41 is welded and fixed to the right side of the box body 1, a belt conveyor 42 is fixedly installed on the inner wall of the base 41, and a magnet 43 is fixedly installed on the inner wall of the base 41 inside the belt conveyor 42.

[0051] The magnet 43 is arranged in the conveyor belt of the belt conveyor 42, so that the ferromagnetic metal can be adsorbed on the surface of the conveyor belt. Through the uninterrupted operation of the belt conveyor 42, the ferromagnetic metal can be effectively prevented from accumulating in one place, thereby affecting the adsorption effect of the conveyor belt on the metal.

[0052] In this embodiment, a feed plate 44 is welded to the inner wall of the base 41, the right side of the feed plate 44 is welded to the right side of the box body 1, a discharge plate 45 is welded to the lower surface of the feed plate 44, a return spring 46 is welded to the lower surface of the discharge plate 45, a support plate 47 is welded to the lower surface of the return spring 46, and the surface of the support plate 47 is welded and fixed to the inner wall of the base 41.

[0053] The return spring 46 has a certain elasticity, so that the discharge plate 45 can move downward in time after moving upward to reset. The feed plate 44 and the discharge plate 45 are both tilted to the right at a certain angle, and the tilt angle of the feed plate 44 is greater than the tilt angle of the discharge plate 45, so that the mud and sand particles can better enter the discharge plate 45.

[0054] Furthermore, the inner wall of the support plate 47 is rotatably connected to a second rotating rod 48, the surface of the second rotating rod 48 is transmission-connected to the surface of the first rotating rod 32 via a first belt 410, a special-shaped plate 49 is welded to the surface of the second rotating rod 48, and the surface of the special-shaped plate 49 is in contact with the lower surface of the discharge plate 45.

[0055] By setting the special-shaped plate 49, an upward impact force can be applied to the discharge plate 45, causing the discharge plate 45 to vibrate, thereby causing the mud and sand particles on the discharge plate 45 to vibrate or jump greatly, so that the metal in the mud and sand particles can better contact with the belt conveyor 42, and at the same time, it also avoids the accumulation of mud and sand particles on the discharge plate 45, thereby greatly improving the efficiency of metal separation. There are two second rotating rods 48, and the two second rotating rods 48 are connected by a belt drive, and can rotate synchronously.

[0056] The metal collecting mechanism 5 includes a second threaded rod 51, the surface of the second threaded rod 51 is rotatably connected to the inner wall of the base 41, the surface of the second threaded rod 51 is transmission connected to the surface of the first rotating rod 32 through a second belt 54, the surface of the second threaded rod 51 is threadedly connected to a push plate 52, the lower surface of the push plate 52 is in contact with the upper surface of the collecting box 53, and the surface of the collecting box 53 is fixedly mounted to the inner wall of the base 41.

[0057] Through the transmission connection between the second threaded rod 51 and the first rotating rod 32 , the second threaded rod 51 can realize forward and reverse rotation, thereby driving the push plate 52 to push the metal on the surface of the belt conveyor 42 into the collection boxes 53 on both sides of the belt conveyor 42 .

[0058] Working principle: the rotation of the motor 31 drives the first rotating rod 32 to rotate. The rotation of the first rotating rod 32 drives the worm 33 to rotate, the worm 33 drives the worm wheel 34 to rotate, and the worm wheel 34 drives the first threaded rod 35 to rotate, so that the filter plate 36 moves to the right side of the box body 1, and the filter plate 36 drives the tooth plate 37 to move to the right side of the box body 1. When the filter plate 36 moves a certain distance, the tooth plate 37 meshes with the first gear 24, thereby driving the first gear 24 to rotate clockwise by a certain angle, so that the water inlet baffle 25 rotates clockwise, thereby the water inlet baffle 25 is The filter plate 36 is blocked by the tooth plate 37, so that the water inlet 22 stops taking in water, and the filter plate 36 continues to drive the tooth plate 37 to move to the right side of the box body 1. When the tooth plate 37 is engaged with the second gear 262, it drives the second gear 262 to rotate clockwise, and then drives the rotating shaft 261 to rotate clockwise. The rotating shaft 261 drives the flapping plate 263 to move clockwise and contact the filter plate 36. The filter plate 36 is subjected to the impact force from the flapping plate 263, which generates vibration, so that the mud and sand particles on the surface of the filter plate 36 fall into the feed plate 44, and then slide from the feed plate 44 into the discharge plate 45.

[0059] At the same time, the first rotating rod 32 drives the second rotating rod 48 to rotate through the first belt 410, and then drives the special-shaped plate 49 to rotate. When the protrusion on the surface of the special-shaped plate 49 contacts the discharge plate 45, the discharge plate 45 is driven to move upward. When the protrusion on the surface of the special-shaped plate 49 does not contact the discharge plate 45, the return spring 46 drives the discharge plate 45 to move downward, and so on and so forth, so that the discharge plate 45 continues to move up and down, thereby driving the mud and sand particles on the surface of the discharge plate 45 to vibrate or jump greatly. The metal in the mud and sand particles is attracted by the magnet 43, and then adsorbed on the surface of the belt conveyor 42 and moves with the belt conveyor 42. At the same time, the first rotating rod 32 drives the second threaded rod 51 to rotate through the second belt 54, thereby causing the push plate 52 to move back and forth, and pushes the metal adsorbed on the surface of the belt conveyor 42 into the collection box 53.

[0060] The present invention provides a seawater separation device. There are many methods and ways to implement the technical solution. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention. All components not specified in this embodiment can be implemented by existing technologies.
