Description

Technical Field

[0001] This utility model relates to the field of iron sand magnetic separation vessel technology, specifically to an underwater agitator iron sand magnetic separation vessel. Background Technology

[0002] Rivers, lakes, and seas often contain abundant iron sand resources. Currently, various equipment and methods exist for extracting iron sand from water bodies, but they all suffer from several problems. Traditional magnetic separation equipment is often inefficient and unable to effectively separate iron sand from large quantities of gravel. Some magnetic separation equipment has complex structures and high maintenance costs, making it difficult to widely apply in practical operations. Furthermore, some equipment exhibits poor adaptability to different depths and gravel properties when operating underwater, resulting in unsatisfactory iron sand recovery rates and purity. Therefore, there is an urgent need for a highly efficient, convenient, and adaptable underwater agitator-driven iron sand magnetic separator. This paper presents an underwater agitator-driven iron sand magnetic separator to address these issues. Utility Model Content

[0003] To solve the problems mentioned above, the technical solution adopted by this utility model is: an underwater agitator iron sand magnetic separator, comprising: a hull, a main beam hinged to the bow of the hull, a gearbox provided on the outer side of the end of the main beam, an agitator connected to the main beam through the gearbox, a preliminary magnetic separator installed at the bottom of the main beam, a sand removal hopper provided at the bottom end of the main beam on one side of the preliminary magnetic separator, a fixed frame provided at the upper end of the stern of the hull, a housing fixedly connected to the fixed frame, a drive motor fixedly installed at one end of the fixed frame, the output end of the drive motor extending into the housing and connected to a second-stage fine magnetic separator, a scraper guide plate provided on one side of the housing, and a feed hopper provided on one side of the upper end of the housing.

[0004] As a preferred technical solution of this utility model, a sand-drawing pipe is fixedly connected to one side of the top of the feed hopper by a clamping hoop, and a discharge port is provided on one side of the lower end of the box.

[0005] As a preferred technical solution of this utility model, a motor body is installed on one side of the hull, the output end of the motor body is connected to a main shaft universal joint, one end of the main shaft universal joint is connected to a drive shaft telescopic spline, one end of the drive shaft telescopic spline is connected to a shaft body, and one end of the shaft body is connected to the inside of the gearbox.

[0006] As a preferred technical solution of this utility model, a rinsing pipe is installed at the bottom of the main beam between the preliminary magnetic separator and the desanding hopper, and a water inlet is provided on the side of the rinsing pipe facing the preliminary magnetic separator.

[0007] As a preferred technical solution of this utility model, the desanding hopper slides in contact with the outer circumference of the preliminary magnetic separator on one side, and a sand pump is fixedly installed on the top of the hull near the desanding hopper. The water outlet of the water pump is connected to one end of the sand pumping pipe through a pipe, and the water pumping end extends into the desanding hopper through a pipe.

[0008] As a preferred technical solution of this utility model, a sand pump is fixedly installed on the side of the hull near the sand pumping pipe. The extraction end of the sand pump is connected to the sand removal bucket through a pipe, and the output end of the sand pump is connected to the outlet pipe. A 25kw generator set is installed on the top of the hull near the fixed frame. Its drive components are configured as follows: (1) a sand pumping wheel of 5.5kw, (2) a beam crane of 5.5kw, (3) a sand removal pump of 5.5kw, (4) a secondary magnetic separator of 3kw, (5) a demagnetizing flushing pump of 2kw, and four anchor winches that do not occupy long-term power, totaling 21.5kw, which meets the configuration standard.

[0009] As a preferred technical solution of this utility model, a fixed seat is provided on the top of the hull near the main beam, and a winch is fixedly installed on the top of the fixed seat. The winding end of the winch is connected to the top of the main beam through a steel wire rope. Positioning anchors are installed at the four corners of the hull to control the forward and backward positioning.

[0010] The present invention has the following advantages: the steel wire rope can be raised and lowered by the lifting mechanism, thereby adjusting the elevation angle of the main beam, which in turn facilitates the adjustment of the height of the preliminary magnetic separator and the sand mixing wheel on the main beam, thus making it easier to extract iron sand at different depths under different on-site conditions and improving its practicality.

[0011] The agitator continuously stirs the raw sand in the water, facilitating preliminary magnetic separation by the initial magnetic separator. This utilizes an underwater magnetic field ten times stronger than that on land, resulting in significantly higher output and lower energy consumption. The extracted iron sand is then pumped into a hopper and sent to a finer magnetic separator for further separation, effectively improving the purity of the magnetic material. The system is compact and easy to operate by one person. It is an outstanding project unmatched in the industry. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] Please refer to the following: Figures 1-5This utility model relates to an underwater agitator iron sand magnetic separator, comprising: a hull 1, a main beam 2 hinged to the bow of the hull 1, a gearbox 3 located on the outer side of the end of the main beam 2, an agitator 4 connected to the main beam 2 via the gearbox 3, a preliminary magnetic separator 5 installed at the bottom of the main beam 2, a desanding hopper 6 located on one side of the preliminary magnetic separator 5 at the bottom of the main beam 2, a fixing frame 7 located at the upper end of the stern of the hull 1, a housing 8 fixedly connected to the fixing frame 7, a drive motor 9 fixedly installed at one end of the fixing frame 7, the output end of the drive motor 9 extending into the housing 8 and connected to a secondary fine magnetic separator 10, a scraping guide plate 11 located on one side of the housing 8, and a feed hopper 12 located on one side of the upper end of the housing 8.

[0022] Among them, a sand-draining pipe 13 is fixedly connected to one side of the top of the feed hopper 12 by a clamping hoop; a discharge port 14 is provided on one side of the lower end of the box body 8; a motor body 15 is installed on one side of the hull 1; a main shaft universal joint 16 is connected to the output end of the motor body 15; a drive shaft telescopic spline 17 is connected to one end of the main shaft universal joint 16; and a shaft body 18 is connected to one end of the drive shaft telescopic spline 17. Thus, when the main beam 2 swings up and down to adjust the elevation angle, it does not affect the normal transmission of the shaft body 18. One end of the shaft body 18 is connected to the inside of the gearbox 3; and the bottom of the main beam 2 is located at... A rinsing pipe 19 is installed between the primary magnetic separator 5 and the desanding hopper 6. A spray nozzle is provided on the side of the rinsing pipe 19 facing the primary magnetic separator 5. This not only washes away the impurities collected in the drum of the primary magnetic separator 5 in time, but also mixes the iron sand and water to facilitate pumping by the sand pump 24. The desanding hopper 6 slides in contact with the outer circumference of the primary magnetic separator 5 on one side. A water pump 20 is fixedly installed on the top of the hull 1 near the desanding hopper 6. The water outlet of the water pump 20 is connected to one end of the rinsing pipe 19 through a pipe, and the water pumping end of the water pump 20 extends into the desanding hopper 6 through a pipe.

[0023] A sand dredging pump 24 is fixedly installed on the side of the hull 1 near the sand dredging pipe 13. The extraction end of the sand dredging pump 24 is connected to the sand removal hopper 6 through a pipe, and the output end of the sand dredging pump 24 is connected to the sand dredging pipe 13. A generator set 23 is installed on the top of the hull 1 near the fixed frame 7. The generator set 23 generates electricity to drive the sand agitator 4, and the electric drive lifts the coarse magnetic separator, transmitting electrical energy to various electrical components. A fixed seat 21 is installed on the top of the hull 1 near the main beam 2. A winch 22 is fixedly installed on the top of the fixed seat 21. The winding end of the winch 22 is connected to the top of the main beam 2 through a steel wire rope. The winch 22 can wind up and unwind the steel wire rope, thereby adjusting the elevation angle of the main beam 2, which facilitates the adjustment of the height of the preliminary magnetic separator 5 and the sand agitator 4 on the main beam 2.

[0024] Specifically, in use, the motor body 15 drives the gears in the gearbox 3 through the main shaft universal joint 16, the drive shaft telescopic spline 17, and the shaft body 18. The gears then drive the sand-stirring wheel 4 to rotate and agitate the sand in the water. Simultaneously, the preliminary magnetic separator 5 operates, rotating counterclockwise. The preliminary magnetic separator 5 then transports magnetically adsorbable iron sand from the sand to the sand-removing hopper 6. Water is pumped by the water pump 20 to the rinsing pipe 19, continuously rinsing the surface of the drum of the preliminary magnetic separator 5. This causes water and iron sand to fall into the desanding hopper 6. The sand pump 24 can pump the water and iron sand mixture in the desanding hopper 6 into the feed hopper 12, and then into the fine magnetic separator. The second fine magnetic separator 10 rotates clockwise through the drive motor 9 to magnetically attract the iron sand and water mixture and automatically push it into the bottom of the ship's hold box 8 and discharge it outward through the discharge port 14. The iron sand magnetically attracted by the second fine magnetic separator 10 rotates to the scraper guide plate 11 and is automatically discharged without magnetic ore, so that the iron sand can be magnetically separated again.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0026] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
