Description

Technical Field

[0001] This utility model relates to the technical field of slurry conveying in magnetic separators, and in particular to a slurry conveying device for a laboratory wet magnetic separator. Background Technology

[0002] During the laboratory wet magnetic separator test, the test raw material was first poured into a mixing tank, an appropriate amount of water was added and the concentration was adjusted to a suitable level, and then the mixture was stirred. After the slurry was stirred evenly, the discharge valve at the bottom of the mixing tank was opened, and the slurry was fed into the feed trough of the weak magnetic separator through a hose.

[0003] However, in actual operation, because the mixing tank platform is in contact with the end of the discharge pipe, the end of the discharge hose tilts slightly upwards from the contact point. This prevents it from maintaining a downward tilt when inserted into the feed trough of the weak magnetic separator. Consequently, ore remains in the discharge hose, and the slurry in the mixing tank cannot be completely fed into the weak magnetic separator. Large amounts of water are needed for repeated rinsing, but some denser and larger mineral particles still deposit inside the discharge hose, wasting water and introducing errors into the experimental data. Furthermore, feeding the slurry into the feed trough of the weak magnetic separator via the discharge hose causes the feed to concentrate at a point in the middle of the separator cylinder, rather than being evenly distributed across the surface. This results in concentrate accumulating in a strip of approximately 2 cm in the middle of the cylinder. This accumulated strong magnetic concentrate may contain weakly magnetic or non-magnetic minerals, leading to inaccurate experimental data. Utility Model Content

[0025] Please refer to Figure 1 This utility model discloses a slurry conveying device for a laboratory wet magnetic separator, which includes a tank 1, a cover plate 2 and a support frame.

[0026] The tank 1 is mounted on a support frame, is rectangular in shape, and slopes downwards along its length, with its upper side open. In a preferred embodiment of this invention, the tank 1 is made of stainless steel. A cover plate 2 is installed on the upper side of the tank 1, closing off the lower portion of the upper side of the tank 1. The portion of the upper side of the tank 1 not closed by the cover plate 2 forms a feed inlet 4. The feed inlet 4 is used to receive slurry below the discharge port of the mixing tank. The lower side of the tank 1 along its length is open, forming a discharge port 5, used to input the slurry into the feed port of the magnetic separator. The discharge port 5 and the feed inlet 4 are connected internally through the tank 1.

[0027] After the slurry discharged from the mixing tank's discharge port flows into the tank 1, it flows naturally down the tank 1 under gravity and finally enters the magnetic separator's feed port from the discharge port 5. Compared with the existing technology of feeding ore into the magnetic separator through a discharge hose, this method avoids the situation where ore remains in the discharge hose, thus eliminating the need for repeated rinsing of the discharge hose with large amounts of water, as is required with a discharge hose.

[0028] Specifically, even without the cover plate 2 on the tank 1, the slurry in the discharge port of the mixing tank can still be guided into the feed port of the magnetic separator. However, when the flow rate of the slurry entering the tank 1 is high, or when the inner wall of the tank 1 is later washed with high-pressure water, the slurry and water can easily splash to the outside of the tank 1, which is detrimental to the safety of the staff and the cleanliness of the experimental environment. Therefore, the function of the cover plate 2 is to prevent the slurry or water in the tank 1 from splashing.

[0029] Cover plate 2 is a rectangular plate, with its length aligned with that of the tank 1. The width of cover plate 2 is greater than or equal to the width of the tank 1, and its length is less than the length of the tank 1. Cover plate 2 can be fixed to the tank 1 by welding. The lower edge of the cover plate 2 along its length can be aligned with or not aligned with the lower edge of the tank 1. In practical applications, the specific position of cover plate 2 can be adjusted appropriately according to the size of the feed inlet 4 from which the material needs to flow out.

[0030] When the cover plate 2 is welded to the tank body 1, the cover plate 2 cannot be removed from the tank body 1, increasing the difficulty of cleaning the inner wall of the tank body 1. To avoid this situation, in another embodiment of this utility model, the cover plate 2 is detachably connected to the tank body 1 and can slide along the length direction of the tank body 1. The tank body 1 is provided with a latch to restrict the sliding of the cover plate 2. In other embodiments of this application, the latch can be replaced by a pin, screw, nut, or other component that can restrict the sliding of the cover plate 2.

[0031] For details, please refer to Figure 2 The cover plate 2 has two downward-bent edges along its width direction forming C-shaped sliding portions 6. Long, narrow slide rails 7 are formed on the upper edges of both sides of the groove 1 along its width direction, with their length direction aligned with the length direction of the groove 1, and their longitudinal cross-sectional shape matching the longitudinal cross-sectional shape of the sliding portions 6. By installing the sliding portions 6 onto the slide rails 7, the cover plate 2 can slide along the length direction of the groove 1 to adjust its position. Furthermore, by sliding the cover plate 2 along the length direction of the groove 1, the sliding portions 6 can be disengaged from the slide rails 7, allowing the cover plate 2 to be removed from the groove 1.

[0032] The longitudinal cross-sections of the sliding part 6 and the slide rail 7 can be other suitable shapes, for example, please refer to [reference needed]. Figure 3 In another embodiment of this utility model, the slide rail 7 is elongated. A T-shaped groove 9 is formed on the upper side of the slide rail 7 along its length. Correspondingly, the sliding part 6 is an elongated slider with a T-shaped longitudinal section, which is provided at each of the two edges of the cover plate 2 in the width direction. By embedding the sliding part 6 into the T-shaped groove 9 on the slide rail 7, the cover plate 2 can slide along the length direction of the groove 1 to adjust its position. By sliding the cover plate 2 along the length direction of the groove 1 to disengage the sliding part 6 from the T-shaped groove 9 of the slide rail 7, the cover plate 2 can be removed from the groove 1.

[0033] By making the connection between the cover plate 2 and the tank body 1 detachable and slidable, the position of the cover plate 2 can be easily adjusted, and the size of the feed inlet 4 can be adjusted to accommodate various flow rates of slurry discharged from the discharge port of the mixing tank. The cover plate 2 can also be easily disassembled and reassembled, thus facilitating the flushing of the inside of the tank body 1.

[0034] Please continue to refer to Figure 1The support frame includes four support legs 3. The upper end of each support leg 3 is connected to the lower side of the tank 1. The four support legs 3 are arranged in a rectangular shape, with two support legs 3 supporting the lower end of the tank 1 and the other two support legs 3 supporting the higher end of the tank 1.

[0035] In practical applications, the slurry conveying device of the laboratory wet magnetic separator of this utility model may be used in conjunction with various types of mixing tanks and magnetic separators. Therefore, it is necessary to adjust the height and tilt angle of the tank 1 so that the feed inlet 4 and the discharge outlet 5 can be aligned with the discharge outlet of the mixing tank and the feed inlet of the magnetic separator, respectively; and so that the slurry can flow smoothly from the tank 1.

[0036] To allow for adjustment of the height and tilt angle of the tank 1, the support leg 3 includes an inner rod 31, an outer rod 32, and a limiting member. The outer rod 32 is a hollow structure. The inner rod 31 extends coaxially into the outer rod 32 and can slide along its own axis within the outer rod 32, thereby adjusting the length of the support leg 3. The limiting member is installed on either the inner rod 31 or the outer rod 32 to restrict the sliding of the inner rod 31 within the outer rod 32. The limiting member can be a limiting pin, which restricts the sliding of the inner rod 31 within the outer rod 32 when both the inner rod 31 and the outer rod 32 are inserted simultaneously. Other suitable limiting members include limiting pins, spring clips, and limiting bolts.

[0037] In one embodiment of this utility model, the inner rod 31 and the outer rod 32 are threaded together to realize the sliding of the inner rod 31 on the outer rod 32.

[0038] In another embodiment of this utility model, a rack is provided on the side wall of the inner rod 31. The length direction of the rack is consistent with the length direction of the inner rod 31. A drive motor is provided on the outer wall of the outer rod 32. The output shaft of the drive motor extends into the outer rod 32, and a gear is connected to its end. The gear meshes with the rack, so that the drive motor can drive the inner rod 32 to slide within the outer rod 32.

[0039] Furthermore, to facilitate the movement of the trough 1, each of the support legs 3 is equipped with casters 8 at its lower end. Each caster 8 is self-locking.

[0040] Compared with the existing technology of feeding ore into the magnetic separator through a ore discharge hose, the present invention avoids the situation where ore is stored in the ore discharge hose, and therefore does not require repeated rinsing of the ore discharge hose with a large amount of water as with the ore discharge hose.

[0041] Furthermore, the slurry conveying device of the laboratory wet magnetic separator of this invention has the advantages of simple structure, convenient manufacturing, and easy cleaning, which can effectively avoid the problems of slurry accumulation and concentrated feeding, thereby helping to improve the stability and accuracy of the experiment.

[0042] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
