Description

Technical Field

[0001] The invention relates to the technical field of mineral mining, in particular to a mineral dehydration system and a ship. Background Art

[0002] Mineral dehydration refers to the process of removing water from minerals through various methods and technologies during the mineral processing process to meet the needs of subsequent processing, storage, transportation, etc. Mineral dehydration plays an important role in ensuring the quality of concentrates and is an important part of mineral processing engineering and environmental protection engineering.

[0003] In the relevant technology, the mineral dehydration system on land is developing in the direction of large-scale, good reliability, good dehydration effect or easy maintenance. However, if mining is carried out underwater, the weight of the minerals and the weight of the equipment will put forward extremely high requirements on the ship's load index and deck load-bearing index, and increase the structural weight of the ship, causing the center of gravity to move upward.

[0004] Therefore, it is necessary to develop a new type of mineral dehydration system and vessel to improve some of the above problems existing in the relevant technology. Summary of the invention

[0005] The object of the present invention is to provide a mineral dehydration system and a ship, which can reduce the influence of minerals, water and equipment on the center of gravity of the ship and improve the stability of the ship.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] The mineral dehydration system provided by the present invention includes a support, a first separation device, a second separation device, a first container, a conveying device and a transporting device, wherein the support is used to provide an upper space and a lower space; the first separation device and the second separation device are arranged in the upper space, and are used to separate minerals with a first particle size and a second particle size respectively; the first container is arranged in the lower space, connected to the first separation device, and is used to precipitate a first solid-liquid mixture formed after the minerals with the first particle size are separated; the conveying device is connected to the first container and the second separation device, and is used to transport the first solid-liquid mixture to the second separation device; the transporting device is used to transport the minerals with the first particle size and the second particle size after separation.

[0008] Optionally, the first separation device or the second separation device is connected to the transport device via a separation channel, and the transport device includes at least two transport channels and a movably arranged screening assembly for connecting the separation channels to the transport channels respectively.

[0009] Optionally, the transport channels are arranged at intervals, and the screening assembly can be swingably arranged between the transport channels to open or block the transport channels after swinging.

[0010] Optionally, at least two transport channels extend in different directions.

[0011] Optionally, the bottom cross-sectional dimension of the first container is smaller than the top cross-sectional dimension, and the conveying device is connected to the bottom of the first container.

[0012] Optionally, the mineral dehydration system further includes a feeding device and a storage container, and the feeding device is connected to the transporting device and the storage container.

[0013] Optionally, the feeding device includes a rotary drive assembly and a feeding channel, which is used to drive the end of the feeding channel to swing or rotate to change the landing point of the mineral in the storage container.

[0014] Optionally, the first separation device or the second separation device can be a vibration separation, centrifugal separation, filter press separation or cyclone separation equipment.

[0015] Optionally, the mineral dehydration system also includes a reflux device and a discharge device; the second separation device is a centrifuge, the reflux device is connected to the centrifuge and the first container, and is used to reflux a second solid-liquid mixture formed after the mineral of the second particle size is separated to the first container, and the discharge device is connected to the top of the first container, and is used to discharge the overflow liquid in the first container.

[0016] The present invention provides a ship, comprising a cabin and the above-mentioned mineral dehydration system arranged in the cabin.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention forms an upper and lower space through a bracket, and respectively arranges the separation device and the load-bearing device in an upper and lower layout through the bracket, so as to realize the centralization of the system structure and make the mineral dehydration system compact as a whole, so that the mineral dehydration system can be installed inside the cabin instead of being laid on the deck, which is beneficial to improve the center of gravity position of the ship and enhance the stability of the ship.

[0019] 2. The present invention uses a conveying device to transport the solid-liquid mixture in the first container that has been processed by the first separation device to the second separation device for secondary processing, thereby realizing cyclic processing and obtaining the desired minerals with different particle sizes.

[0020] 3. The present invention sets a screening component at the transport channel, and realizes the opening or blocking of different transport channels through the movement of the screening component. When the first separation device and the second separation device share a separation channel to discharge minerals of different particle sizes, the minerals of different particle sizes can enter different transport channels from the separation channel, thereby realizing the separation and storage of minerals of different particle sizes.

[0021] 4. The present invention changes the cross-sectional dimensions of the first container so that the bottom dimension is smaller than the top dimension, thereby being able to gather the minerals together during precipitation, so as to improve the solid transport efficiency of the conveying device when transporting the solid-liquid mixture, thereby improving the overall working efficiency of the mineral dehydration and separation.

[0022] 5. The present invention provides a feeding device at the end of the transport device so that the minerals can be fed into a predetermined storage container, and when feeding, the end of the feeding channel is swung or rotated by a rotating drive assembly to disperse the mineral landing points, thereby preventing the minerals with a large stacking angle from forming a conical pile when stacked.

[0023] 6. The present invention refluxes the second solid-liquid mixture treated by the centrifuge to the first container through a reflux device, so that the first container is gradually filled. Due to the extremely strong solid-liquid separation ability of the centrifuge, the particle size of the solid particles in the treated second solid-liquid mixture is extremely small. After sedimentation and overflow in the first container, the liquid flowing out of the top of the first container can be re-injected into the sea through the discharge device, which not only meets environmental protection requirements, but also can discharge seawater in real time while processing minerals, reducing the load of the ship, so that it can mine and transport more minerals.

[0033] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0034] The embodiment of the present invention provides a mineral dehydration system, referring to Figure 1 , including a support 9, a first separation device 101, a second separation device 102, a first container 301, a conveying device 4 and a transporting device 5, the support 9 is used to provide an upper space and a lower space; the first separation device 101 and the second separation device 102 are arranged in the upper space, and are used to separate minerals with a first particle size and a second particle size respectively; the first container 301 is arranged in the lower space, connected to the first separation device 101, and is used to precipitate a first solid-liquid mixture formed after the minerals with the first particle size are separated; the conveying device 4 is connected to the first container 301 and the second separation device 102, and is used to transport the first solid-liquid mixture to the second separation device 102; the transporting device 5 is used to transport the minerals with the first particle size and the second particle size after separation.

[0035] In some specific embodiments, referring to Figure 4 The support 9 at least includes a plate-shaped bearing member 901, and the bearing member 901 is horizontally arranged. The upper space and the lower space are respectively formed on both sides of the bearing member 901, that is, the upper side and the lower side shown in the figure.

[0036] In some specific embodiments, referring to Figure 4 The support 9 also includes a partition 902, which divides the upper space and the lower space into multiple areas in the horizontal direction. The first separation device 101 and the second separation device 102 are respectively arranged in the two separated areas of the upper space, and the first container 301 is arranged in a separated area of ​​the lower space.

[0037] In some specific embodiments, referring to Figure 3 , the first container 301 is arranged directly below the first separation device 101, that is, the area where the first separation device 101 is located corresponds to the area where the first container 301 below is located.

[0038] In some specific embodiments, referring to Figure 1 , the first separation device 101 and the second separation device 102 can share a separated area, so that the area where the first separation device 101 and the second separation device 102 are located corresponds to the area where the first container 301 is located below.

[0039] In some specific embodiments, referring to Figure 1 The first separation device 101 and the second separation device 102 together constitute a first group of separation devices 10 arranged in a separated area, and the mineral dehydration system also includes a second group of separation devices, which are arranged in another separated area adjacent to the first group of separation devices 10.

[0040] In some specific embodiments, referring to Figure 1 The transport device 5 is arranged parallel to the extension direction of the carrier 901 and adjacent to the carrier 901, so that after the first separation device 101 or the second separation device 102 on the carrier 901 separates the minerals, the minerals can enter the transport device 5.

[0041] In some specific embodiments, the transport device 5 is also divided into several areas, which correspond one by one to the areas formed by the upper space or the lower space separated by the partition 902.

[0042] In some specific embodiments, referring to Figure 3 The conveying device 4 includes a conveying channel 402 and a conveying pump 401. The conveying pump 401 is arranged in the lower space and is adjacent to the first container 301. The conveying channel 402 connects the first container 301 with the conveying pump 401, and the conveying channel 402 connects the conveying pump 401 with the second separation device 102, so that the original solid-liquid mixture obtained by mining is processed by the first separation device 101 and the second separation device 102 in turn.

[0043] In some embodiments of the present invention, referring to Figure 1 and Figure 3The first separation device 101 or the second separation device 102 is connected to the transport device 5 through a separation channel. The transport device 5 includes at least two transport channels 501 and a movably arranged screening component 6, which is used to connect the separation channels with the transport channels 501 respectively.

[0044] In some embodiments of the present invention, referring to Figure 3 and Figure 7 The transport channels 501 are arranged at intervals, and the screening assembly 6 can be swingably arranged between the transport channels 501 to open or block the transport channels 501 after swinging.

[0045] In some embodiments of the present invention, at least two transport channels 501 extend in different directions.

[0046] In some specific embodiments, a conveyor belt is provided in the transport channel 501 to transport the minerals.

[0047] In some specific embodiments, the separation channel can be a closed channel, that is, the separation channel has only two openings, and the minerals separated by the first separation device 101 or the second separation device 102 are input from one end of the separation channel and output to the transport device 5 from the other end.

[0048] In other specific embodiments, the separation channel may be semi-open, that is, the separation channel only has a bottom track, and the top and sides of the channel are not closed.

[0049] In other specific embodiments, the separation channel can be fully open, and the transport device 5 partially extends to the bottom of the first separation device 101 or the second separation device 102, so that the minerals fall directly into the transport device 5 below after being separated. The separation channel represents the path channel for the minerals to fall.

[0050] In some specific embodiments, referring to Figure 1 At least two of the transport channels 501 are arranged in parallel, but their transport directions are opposite. For example, the transport direction of one of the transport channels 501 is upward as shown in the figure, and the transport direction of the other transport channel 501 is downward as shown in the figure, so as to adapt to the narrow structural shape of the cabin.

[0051] In some specific embodiments, referring to Figure 3 and Figure 7The screening assembly 6 includes a barrier 601, which is arranged one by one in several areas of the transport device 5 and corresponds to the separation channel of the first separation device 101 or the second separation device 102, so that the separated minerals can fall into the barrier 601 and pass through the barrier 601 to fall into the transport channel 501 below the barrier 601.

[0052] In some specific embodiments, referring to Figure 3 and Figure 7 The screening assembly 6 includes a swinging member 602, which is movably disposed in the enclosure 601 and is located between two adjacent conveying channels 501. When the swinging member 602 swings, the swinging member 602 abuts against the inner walls on both sides of the enclosure 601 respectively.

[0053] Exemplarily, when the swinging member 602 swings toward the transport channel 501 on one side, the end of the swinging member 602 abuts against the inner wall of the enclosure 601 close to the transport channel 501 on that side, so that the transport channel 501 on that side is shielded by the swinging member 602, that is, when minerals fall into the enclosure 601, part of them falls directly into the transport channel 501 on the other side, and part of them falls into the transport channel 501 on the other side after being blocked by the swinging member 602, so that the transport channel 501 on this side does not transport minerals.

[0054] For example, when the swing member 602 swings to the middle area on both sides, the minerals can fall into the transport channels 501 on both sides at the same time, thereby realizing two-way transport of the same type of minerals.

[0055] In some embodiments of the present invention, referring to Figure 3 The bottom cross-sectional dimension of the first container 301 is smaller than the top cross-sectional dimension, and the conveying device 4 is connected to the bottom of the first container 301 .

[0057] In some specific embodiments, referring to Figure 3 , the delivery channel 402 is connected to the bottom of the cross-sectional size.

[0058] In some specific embodiments, the cross-sectional shape of the first container 301 may be circular or polygonal.

[0059] In some specific embodiments, referring to Figure 3The top edge of the first container 301 abuts against the supporting member 901 , and the bottom of the first separation device 101 discharges the first solid-liquid mixture into the first container 301 .

[0060] In some specific embodiments, referring to Figure 3 , the bottom of the first container 301 is at the same height as the position of the delivery pump 401.

[0061] In some specific embodiments, referring to Figure 3 The delivery channel 402 connecting the bottom of the first container 301 and the delivery pump 401 is arranged horizontally.

[0062] In some embodiments of the present invention, referring to Figure 2 and Figure 5 The mineral dehydration system further comprises a feeding device 7 and a storage container, wherein the feeding device 7 is connected to the transporting device 5 and the storage container.

[0063] In some specific embodiments, referring to Figure 2 and Figure 5 The feeding device 7 is arranged on the transporting device 5, and the mineral enters the feeding device 7 after being transported through the transporting channel 501, so that the mineral is put into the storage container.

[0064] In some embodiments of the present invention, referring to Figure 5 The feeding device 7 includes a rotating drive component 702 and a feeding channel 701, which is used to drive the end of the feeding channel 701 to swing or rotate to change the landing point of the mineral in the storage container.

[0065] In some specific embodiments, the rotation driving assembly 702 may include a motor, which is not limited in the present invention.

[0066] In some specific embodiments, the output shaft direction of the motor may be 90° to the extension direction of the feeding channel 701, so that the feeding channel 701 can swing or rotate in a plane perpendicular to the output shaft of the motor.

[0067] In some specific embodiments, the angle between the extension direction of the feeding channel 701 and the output shaft direction of the motor can be less than 90°, forming an acute angle, so that the radius of the circular motion of one end of the feeding channel 701 is smaller than the radius of the circular motion of the other end, and the overall trajectory is conical.

[0068] In some specific embodiments, the rotary drive assembly 702 also includes a speed control module for adjusting the swing speed or rotation speed of the feeding channel 701, thereby changing the landing point of the mineral in the storage container, which is beneficial to improving the distribution uniformity of the mineral in the storage container.

[0069] Exemplarily, when the swing speed or the rotation speed of the feeding channel 701 increases, the mineral accumulation point is close to the edge position of the bottom of the storage container.

[0070] Exemplarily, when the swing speed or the rotation speed of the feeding channel 701 decreases, the mineral accumulation point is close to the center position of the bottom of the storage container.

[0071] In some specific embodiments, the speed regulation module may be a frequency converter or other motor control tools.
