Description

Technical Field

[0001] This utility model relates to the field of magnetic separation ship technology, and in particular to hydraulic vacuum magnetic separation ship. Background Technology

[0002] Hydraulic vacuum magnetic separators, as an advanced equipment integrating efficient collection and separation, play an important role in the mining of magnetic minerals such as iron sand and in river dredging. However, compared with traditional hydraulic vacuum magnetic separators, they have some structural shortcomings that limit their mining efficiency and scope of application. The main structural problems of traditional hydraulic vacuum magnetic separators are as follows: First, the throat design is unreasonable, resulting in insufficient vacuum and affecting sand suction efficiency; second, the lifting capacity is limited, making it difficult to meet the lifting needs of heavy objects; and third, the configuration of the magnetic separator is not optimized, affecting the separation efficiency and purity. Utility Model Content

[0003] The hydraulic vacuum magnetic separator proposed in this invention solves the problems of insufficient sand suction efficiency, limited lifting capacity, and poor separation purity of existing hydraulic vacuum magnetic separators.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A hydraulic vacuum magnetic separator includes a magnetic separator body. A gantry crane is fixedly connected to the top of the magnetic separator body at one end, and a lifting mechanism is provided on the top of the gantry crane. An operating room is provided on the side of the gantry crane, and an opening is provided in the lower middle part of the operating room. An adjustable high-pressure vacuum throat is provided inside the opening. An installation beam is fixedly installed on the top of the magnetic separator body at the other end, and a separation mechanism is provided inside the installation beam.

[0006] The separation mechanism includes a coarse belt magnetic separator and a fine magnetic separator. The coarse belt magnetic separator is located in the middle of the mounting beam, and the fine magnetic separator is located at the top of the mounting beam. The iron sand in the raw sand first enters the coarse belt magnetic separator for preliminary separation, and then enters the fine magnetic separator for further separation.

[0007] Preferably, the lifting mechanism includes a gantry crane motor, a mounting base, a wire rope, a winding reel, a driving synchronous pulley, a driven synchronous pulley, and a synchronous belt. The gantry crane frame is provided with a mounting base at the top, a winding reel is provided inside the mounting base, and a wire rope is sleeved on the outside of the winding reel. The side end of the wire rope is connected to a high-pressure vacuum throat.

[0008] Preferably, a gantry crane motor is fixedly installed on the side of the mounting base at the top of the gantry crane frame, and an active synchronous pulley is installed at the output end of the gantry crane motor. A driven synchronous pulley is installed on the side of the winding reel, and the driven synchronous pulley is located outside the mounting base. The active synchronous pulley and the driven synchronous pulley are connected by a synchronous belt drive.

[0009] Preferably, work lights are installed on both sides of the top of the operating room, and operating doors are provided on both sides of the operating room.

[0010] Preferably, a self-priming clean water centrifugal pump is provided on the crotch side, and a water suction pipe is connected to the bottom of the self-priming clean water centrifugal pump. A sand suction pipe is connected to the side of the self-priming clean water centrifugal pump, and a high-pressure vacuum throat pipe is connected to the side end of the sand suction pipe.

[0011] Preferably, iron sand bins are provided on both sides of the opening inside the magnetic separator body, and a diesel generator is provided on the side of the mounting beam. The exhaust pipe of the diesel generator passes through the inside of the magnetic separator body and is connected to the water surface.

[0012] Preferably, the separation mechanism further includes a roller screen, a sand inlet pipe, a sand inlet hopper, a sand flushing water pipe, a drain pipe, a first tail material conveying pipe, a second tail material conveying pipe, and pipe valves. The roller screen is installed at the bottom of the mounting beam. The bottom of the roller screen is connected to a self-priming clean water centrifugal pump via pipe valves. The first tail material conveying pipe is connected to the side of the roller screen. The side of the roller screen is connected to a coarse belt magnetic separator via a sand inlet pipe. The coarse belt magnetic separator is connected to a fine magnetic separator via a sand flushing water pipe. A drain pipe is provided on the side of the sand flushing water pipe.

[0013] Preferably, the coarse belt magnetic separator is connected to a second tailings conveying pipe on its outer side, and a sand inlet hopper is fixedly connected to the side of the mounting beam. The fine magnetic separator is fixedly connected to the sand inlet hopper, and the sand inlet hopper is connected to the inside of the iron sand bin.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This water pressure vacuum magnetic separator features a high-pressure vacuum throat. A self-priming clean water centrifugal pump draws water to form a high-pressure water column that is directed towards the throat, generating a powerful high-pressure vacuum. This, in turn, produces a strong vacuum suction force, effectively extracting raw sand from the riverbed. At the same time, it avoids wear and tear on the self-priming clean water centrifugal pump, significantly improving the sand extraction efficiency of the magnetic separator.

[0016] 2. The lifting mechanism adopts high-strength steel wire rope and high-power gantry crane motor to ensure the safe lifting of heavy objects. The gantry crane motor drives the winding reel to wind up through the active synchronous pulley, driven synchronous pulley and synchronous belt of the transmission connection, so as to achieve lifting and ensure that the sand suction pipe and high-pressure vacuum throat can be lifted smoothly. At the same time, the position can be adjusted stably, which helps to improve the sand suction efficiency. In addition, the gantry crane adopts an overweight design to enhance the stability and load-bearing capacity of the overall structure.

[0017] 3. First, the raw sand from the riverbed enters the roller screen for sand and gravel separation. Then, the raw sand undergoes preliminary iron sand separation by passing through the coarse belt magnetic separator, recovering most of the iron sand. Subsequently, the fine magnetic separator uses neodymium iron boron material with high magnetic energy product to further purify the iron sand, ensuring the purity and quality of the final product and significantly improving the separation purity and quality.

[0018] In summary, the ship's design technology is advanced and currently advocates for energy conservation, environmental protection, high output, and low consumption. One person can operate the entire production line. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Reference Figures 1-6 This utility model provides a technical solution: a hydraulic vacuum magnetic separator, including a magnetic separator body 1, a gantry crane 2 fixedly connected to the top of the magnetic separator body 1 at one end, and a lifting mechanism provided on the top of the gantry crane 2, an operating room 3 provided on the side of the gantry crane 2, and an opening 4 provided in the lower middle part of the operating room 3, and an adjustable high-pressure vacuum throat 5 provided inside the opening 4.

[0029] In a specific embodiment, the main body of the magnetic separator vessel is 18 meters long, 7.5 meters wide, and 1.5 meters deep, with a displacement of 86 tons. It is equipped with 22 sets of 110kW diesel generators and 18 8-inch self-priming centrifugal pumps with a pumping capacity of 70kW each, producing 500 cubic meters of water per hour. The vacuum sand extraction process can separate 200 tons of yellow sand with a sand concentration of 40% and 4 tons of iron sand per hour with a 2% iron sand content, resulting in a daily output of 80 tons of iron sand over 20 hours. The 22 sets of 110kW diesel generators supply 9 gantry crane motors (5.5kW each), 4*4 = 16kW motors, 24 roller screens (40-1 = 5kW motors), 7 coarse belt magnetic separators (40-1 = 5kW motors), and 8 fine magnetic separators (4kW motors), totaling 94.5kW * 1.2 = 113kW, which meets the standard configuration.

[0030] Reference Figure 2 , Figure 3The lifting mechanism includes a gantry crane motor 9, a mounting base 10, a wire rope 11, a winding reel 12, a driving synchronous pulley 13, a driven synchronous pulley 14, and a synchronous belt 15. The mounting base 10 is located on the top of the gantry crane frame 2. The winding reel 12 is located inside the mounting base 10, and the wire rope 11 is sleeved on the outside of the winding reel 12. The side end of the wire rope 11 is connected to the high-pressure vacuum throat pipe 5 and the sand extraction pipe 20. The gantry crane motor 9 is fixedly installed on the side of the mounting base 10 at the top of the gantry crane frame 2. The driving synchronous pulley 13 is installed at the output end of the gantry crane motor 9, and the driven synchronous pulley 14 is installed on the side end of the winding reel 12. The driven synchronous pulley 14 is located outside the mounting base 10. The driving synchronous pulley 13 and the driven synchronous pulley 14 are connected by a synchronous belt 15. Thus, in the opening 4, the high-pressure vacuum throat pipe 5 and the sand extraction pipe 20 can be raised and lowered freely by 20 meters through the gantry crane motor 9.

[0031] Reference Figure 4 The top of the operating room 3 is equipped with work lights 16 on both sides, which can provide sufficient light to ensure safe operation at night. The operating room 3 is also equipped with operating doors 17 on both sides. Iron sand bins 21 are set inside the magnetic separator body 1 on both sides of the opening 4. A diesel generator 22 is set on the side of the mounting beam 6. The exhaust pipe 23 on the top of the diesel generator 22 runs through the inside of the magnetic separator body 1 and connects to the water surface to ensure the environmental protection of the emissions.

[0032] In practical implementation, when the hydraulic vacuum magnetic separator is adjusted, the gantry crane motor 9 is started first according to the riverbed depth. The gantry crane motor 9 is equipped with a reducer (not shown in the figure) to drive the active synchronous pulley 13 to rotate. Since the active synchronous pulley 13 and the driven synchronous pulley 14 are connected by a synchronous belt 15, the driven synchronous pulley 14 drives the winding reel 12 to rotate synchronously with the active synchronous pulley 13. Since the winding reel 12 is fitted with a steel wire rope 11 and connected to the high-pressure vacuum throat pipe 5, the high-pressure vacuum throat pipe 5 and the sand suction pipe 20 can be smoothly and freely adjusted under the winding of the winding reel 12 driven by the gantry crane motor 9. After being adjusted to a suitable position, it helps to improve the sand suction efficiency. At the same time, the diesel generator 22 is driven to provide power support for the entire ship. The exhaust pipe 23 at the top of the diesel generator 22 runs through the interior of the magnetic separator body 1 and connects to the water surface to ensure the environmental protection of the emissions. Through the above operations, it provides strong support for the efficient and environmentally friendly development of the mining industry.

[0033] Example 2

[0034] Reference Figure 5This embodiment is an optimization based on Embodiment 1. A mounting beam 6 is fixedly installed on the top of the magnetic separation vessel body 1 at the other end. A separation mechanism is set inside the mounting beam 6. The separation mechanism includes a coarse belt magnetic separator 7 and a fine magnetic separator 8. The coarse belt magnetic separator 7 is set in the middle of the mounting beam 6. The coarse belt magnetic separator 7 utilizes the advantages of magnetic guide plates and dual magnetic poles to save two-thirds of the cost of magnetic pole arrangement. The fine magnetic separator 8 is set on the top of the mounting beam 6. The iron sand in the raw sand first enters the coarse belt magnetic separator 7 for initial large-area suction separation, and then enters the fine magnetic separator 8 for further separation to separate the iron sand with higher purity.

[0035] Reference Figure 4 , Figure 5 The separation mechanism also includes a roller screen 24, a sand inlet pipe 25, a sand inlet hopper 26, a sand flushing water pipe 27, a drainage pipe 28, a first tail material conveying pipe 29, a second tail material conveying pipe 30, and a pipeline valve 31. The roller screen 24 is installed at the bottom of the mounting beam 6. The roller screen 24 is typically a GS1230 model. The bottom of the roller screen 24 is connected to a self-priming clean water centrifugal pump 18 via the pipeline valve 31, and the first tail material conveying pipe is connected to the side of the roller screen 24. Pipe 29, the side end of the roller screen 24 is connected to the coarse belt magnetic separator 7 via sand inlet pipe 25. The coarse belt magnetic separator 7 is connected to the fine magnetic separator 8 via sand flushing water pipe 27, and a drain pipe 28 is provided on the side of the sand flushing water pipe 27. The outer side of the coarse belt magnetic separator 7 is connected to the second tail material conveying pipe 30, and the side of the mounting beam 6 is fixedly connected to the sand inlet hopper 26. The fine magnetic separator 8 is fixedly connected to the sand inlet hopper 26, and the sand inlet hopper 26 is connected to the inside of the iron sand bin 21.

[0036] Reference Figure 6 A self-priming centrifugal water pump 18 is installed on the side of the opening 4. The self-priming centrifugal water pump 18 draws clean water to generate a high-pressure vacuum, and has a one-in-two-out principle, front pumping and rear discharge. The new rear discharge mode uses 8 kg water pressure to pump forward and downward for 20 meters, with a flow rate of 1000 cubic meters per hour, and discharges tail material to a distance of 1000 meters. The flow rate of 1000 cubic meters per hour does not reduce the total flow rate and concentration, improves overall efficiency, saves working time, is more energy-saving, environmentally friendly, and highly productive, and reduces energy consumption. The bottom of the self-priming centrifugal water pump 18 is connected to a suction pipe 19, and the side of the self-priming centrifugal water pump 18 is connected to a sand suction pipe 20. The sand suction pipe 20 is divided into a flushing pipe and a suction pipe. The forward flow is the flushing pipe, and the 180-degree turn is the reverse flow, which is the suction pipe. It can be lifted up and down freely in the opening 4, and the side end of the sand suction pipe 20 is connected to a high-pressure vacuum throat pipe 5.

[0037] In practical implementation, the hydraulic vacuum magnetic separator vessel, when performing separation, first drives the self-priming clean water centrifugal pump 18. The self-priming clean water centrifugal pump 18 draws water through the suction pipe 19 and forms a high-pressure water column that is shot towards the high-pressure vacuum throat pipe 5, generating a powerful water high-pressure vacuum, which in turn generates a strong vacuum suction. Because the sand suction pipe 20 has a downward-facing suction port welded to its head, the raw sand from the riverbed is effectively drawn through the suction port. Next, the raw sand enters the roller screen 24 through the sand suction pipe 20. Then, the roller screen 24 is started, separating the raw sand into sand and gravel. The separated waste stone is discharged outside the vessel through the first tail material conveying pipe 29. Then, the separated sand enters the coarse belt magnetic separator 7 through the sand inlet pipe 25. Simultaneously, the self-priming clean water centrifugal pump 18 provides cleaning water through the pipeline valve 31 to ensure the system... The continuous and efficient operation of the system provides washing water to the inside of the coarse belt magnetic separator 7. Then, the coarse belt magnetic separator 7 is started again to perform preliminary iron sand separation. At the same time, the washing water is discharged through the drain pipe 28. Subsequently, the preliminarily separated iron sand enters the fine magnetic separator 8 through the sand flushing water pipe 27. Since the fine magnetic separator 8 is inclined, the separated tailings and washing water flow back into the coarse belt magnetic separator 7 due to gravity. Since the coarse belt magnetic separator 7 is connected to the outside of the second tailings conveying pipe 30, the tailings are discharged outside the ship through the second tailings conveying pipe 30. Then, the fine magnetic separator 8 uses neodymium iron boron material with high magnetic energy product and rollers to further purify the iron sand, separate out the iron sand with higher purity, and concentrate it in the sand inlet hopper 26. It is then sent to the iron sand bin 21 for storage through the sand inlet hopper 26. Through the above operations, the separation purity and efficiency are significantly improved.

[0038] Furthermore, this water pressure vacuum pump-assisted sand suction vessel features front-pull and rear-discharge magnetic separation. Its advanced design technology is currently promoting energy conservation, environmental protection, high output, and low consumption. One operator can complete the entire production process. The vessel features a central opening 4, within which the sand suction pipe 20 can freely rise and fall. A gantry crane 2 is installed at the front of the opening 4, with a lifting mechanism mounted on it. The lifting angle is achieved by the up-and-down rewinding of steel wire rope 11. This vessel incorporates five unique technologies:

[0039] 1. Pumping clean water and externally suctioning sand.

[0040] 2. The sand suction pipe has a 20mm opening and a variable connector. The opening and suction pipe inlet are designed to suction sand.

[0041] 3. Self-priming centrifugal water pump 18 with one inlet and two outlets, operating on the principle of front pumping and rear discharge.

[0042] 4. A coarse belt magnetic separator 7 was designed, and the magnetic guide plate was designed to utilize the dual magnetic fields to achieve a recovery rate of 95%, thus giving full play to the technical advantages.

[0043] 5. A fine magnetic separator 8 was designed, with high, medium and low magnetic fields arranged, achieving a sorting accuracy of 60% grade.

[0044] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
