Description

Technical Field

[0001] This utility model relates to the technical field of mineral processing shaking table equipment, specifically to a high-efficiency mineral zoning shaking table surface. Background Technology

[0002] Shaking table gravity separation and screening are important operations in the mineral processing industry. Shaking table gravity separation can be used to separate minerals of different densities, obtaining light and heavy mineral products. Screening can classify ores according to particle size to facilitate subsequent beneficiation, smelting, or processing. Shaking table gravity separation and screening are two completely different operations. After shaking table gravity separation, two products, heavy and light minerals, are obtained. They need to be slurried again and then pumped to the screen for screening. Currently, the equipment cannot complete the separation in one process.

[0003] Therefore, the patent application number CN202323506843.2 discloses a novel shaking table surface for ore sorting. By installing a detachable heavy mineral screening table and a light mineral screening table, heavy minerals and light minerals are screened separately on the corresponding screening tables under the action of water flow and vibration, which can simultaneously complete the gravity separation and screening of minerals. However, since zirconium particles are usually more adhesive than some other common ore particles, they are prone to adhering to the screening table surface during the screening process. Moreover, the screening table surface of this patent is a common screen structure, which is not efficient enough and therefore easily leads to clogging of the screening table surface. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a high-efficiency mineral separation shaking table surface that can not only simultaneously complete mineral gravity separation and screening, but also has higher screening efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency mineral separation shaking table includes a shaking table surface and a gravity separation bed surface, a light ore screening bed surface, and a heavy ore screening bed surface disposed on the shaking table surface. The gravity separation bed surface has multiple separation bars for separating light and heavy minerals. The light ore screening bed surface is arranged side by side with the gravity separation bed surface, and the heavy ore screening bed surface is disposed at one end of the gravity separation bed surface and the light ore screening bed surface. The light ore screening bed surface has multiple first bed bars for screening light minerals, the first bed bars are parallel to the separation bars, and the top of the first bed bars has screen holes and multiple grooves are formed along the length direction. The heavy ore screening bed surface has multiple second bed bars for screening heavy minerals, the second bed bars intersect with the separation bars, and the second bed bars have screen holes arranged in a wavy cross-section.

[0007] As an optional solution, one side of the gravity separation bed is the mineral feed side, and the other side of the gravity separation bed is the light ore discharge side.

[0008] As an optional solution, a first channel for conveying heavy minerals is formed between every two sorting bars, with one end of the first channel serving as the first heavy mineral discharge end.

[0009] As an optional solution, a second channel for conveying residual heavy minerals is formed between every two first bed strips, with one end of the second channel serving as the discharge end for the second heavy minerals.

[0010] As an alternative, the top of the second bed strip is flush with the bottom of the first and second grooves.

[0011] As an optional solution, the cross-section of the first bed strip is trapezoidal, and the groove is arc-shaped and extends through both sides of the first bed strip.

[0012] As an optional solution, the shaking table has a first inner opening and a second inner opening; the two sides of the light ore screening table are detachably connected to the first inner opening by bolts; the two sides of the heavy ore screening table are detachably connected to the second inner opening by bolts.

[0013] By adopting the above technical solution, this utility model will have the following beneficial effects:

[0014] This utility model provides a high-efficiency mineral separation shaking table surface. By setting separation bars on the gravity separation bed surface, light minerals and heavy minerals can be separated. The first bed bar has screen holes at the top and multiple grooves along its length, creating numerous small protrusions and depressions on the surface of the light mineral screening bed. The second bed bar has screen holes arranged in a wavy cross-section, creating a wavy surface for the heavy mineral screening bed. By setting the first bed bar parallel to the separation bars and the second bed bar intersecting with them, when the shaking table surface vibrates back and forth, light mineral particles flow along the protrusions and depressions of the light mineral screening bed surface, while heavy minerals flow along the heavy mineral screening bed. The wavy surface flow increases the sliding path and fluidity of mineral particles, reducing particle residence time and making it easier for particles to pass through the two screening beds. The irregular design of the two screening bed surfaces enhances the vibration effect, causing the screen holes to generate more micro-vibrations and undulations during vibration. These micro-vibrations and undulations increase the jumping and sliding of particles on the screen surface, promoting particle separation and passage. Moreover, the irregular surface of the two screening bed surfaces also increases the roughness of the two screening bed surfaces, which increases their friction with the particles. The greater friction makes it more difficult for particles to stick to the screen, thus reducing adhesion.

[0015] Compared with the existing technology, this utility model can not only complete the gravity separation and screening of minerals at the same time, but also has higher screening efficiency and is convenient for screening mineral particles with strong adhesion. Attached Figure Description

[0025] Please refer to Figure 1-4 In one embodiment of a high-efficiency mineral separation shaking table surface according to this utility model, the high-efficiency mineral separation shaking table surface includes a shaking table surface 1 and a gravity separation bed surface 2, a light ore screening bed surface 3, and a heavy ore screening bed surface 4 disposed on the shaking table surface 1. The shaking table surface 1 moves due to the action of the motor, but it is not just simple vibration, but a reciprocating motion along the Y-axis. This is because the spring is compressed and forms tension. While compression and tension occur, the angle between the elbow plate between the spring and the eccentric shaft also changes from large to small. Therefore, the moving speed of the elbow plate changes from slow to fast, causing the forward movement of the shaking table surface 1 to become from slow to fast, and the backward movement to be the opposite. This reciprocating irregular motion separates the mineral particles on the shaking table surface 1 according to their specific gravity. Combined with the flushing water along the positive X-axis to wash the mineral particles, the separation effect is increased. The above is a simple working principle of the existing mineral processing shaking table, which will not be described in detail here.

[0026] The gravity separation bed 2 has multiple separating bars 21 for separating light and heavy minerals. The light mineral screening bed 3 is arranged side-by-side with the gravity separation bed 2, and the heavy mineral screening bed 4 is located at one end of both the gravity separation bed 2 and the light mineral screening bed 3. Importantly, the light mineral screening bed 3 has multiple first bed bars 31 for screening light minerals. The first bed bars 31 are parallel to the separating bars 21, and each first bed bar 31 has screen holes at its top and multiple grooves 32 along its length, creating numerous small protrusions and depressions on the surface of the light mineral screening bed 3. The heavy mineral screening bed 4 has multiple second bed bars 41 for screening heavy minerals. The second bed bars 41 intersect with the separating bars 21, and each second bed bar 41 has screen holes arranged in a wavy cross-section, creating a wavy surface on the surface of the heavy mineral screening bed 4. Both the first bed bars 31 and the second bed bars 41 are hollow, allowing the screened mineral particles to fall through the screen and be collected. Because the shaking table bed 1 vibrates back and forth (in both directions of the Y-axis), light mineral particles flow along the protrusions and depressions of the light mineral screening bed 3, while heavy minerals flow along the wavy surface of the heavy mineral screening bed 4. This increases the sliding path and flowability of the mineral particles, reduces the particle residence time, and makes it easier for particles to pass through the two screening bed surfaces. The irregular design of the two screening bed surfaces enhances the vibration effect, causing the screen holes to generate more micro-vibrations and ripples during vibration. These micro-vibrations and ripples increase the jumping and sliding of particles on the screen surface, promoting particle separation and passage. Moreover, the irregularity of the two screening bed surfaces also increases the roughness of the two screening bed surfaces, which increases their frictional force on the particles. The greater frictional force makes it more difficult for particles to be fixed on the screen, thereby reducing adhesion.

[0027] Specifically, one side of the gravity separation bed 2 is the mineral feed side 22. After being crushed and ground, zirconium ore enters the gravity separation bed 2 evenly from the mineral feed side 22 through the feed trough. The other side of the gravity separation bed 2 is the light ore discharge side 23, which connects to the light ore screening bed 3. The light ore discharge side 23 facilitates the transport of the sorted light minerals to the light ore screening bed 3.

[0028] Specifically, a first channel 24 for conveying heavy minerals is formed between every two sorting bars 21. One end of the first channel 24 is a first heavy mineral discharge end 25 connected to the heavy mineral screening bed 4. The sorted heavy minerals are easily conveyed to the heavy mineral screening bed 4 through the first channel 24 and the first heavy mineral discharge end 25.

[0029] Specifically, a second channel 33 for conveying residual heavy minerals is formed between every two first bed strips 31. One end of the second channel 33 is a second heavy mineral discharge end 34 connected to the heavy mineral screening bed surface 4. The second channel 33 and the second heavy mineral discharge end 34 facilitate the conveying of coarse heavy minerals mixed in with light minerals to the heavy mineral screening bed surface 4.

[0030] More specifically, the top of the second bed strip 41 is flush with the bottom of the first channel 24 and the second channel 33, which facilitates the input of heavy minerals into the heavy mineral screening bed surface 4.

[0031] Specifically, the cross-section of the first bed strip 31 is isosceles and trapezoidal, the groove 32 is arc-shaped and runs through both sides of the first bed strip 31, the inner wall of the groove 32 and the top surface of the first bed strip 31 are areas where sieve holes are distributed, and the bottom of every two adjacent first bed strips 31 is spaced by a second channel 33.

[0032] Specifically, the shaking table surface 1 has a first inner opening and a second inner opening; the light ore screening table 3 is detachably connected to the first inner opening on both sides by bolts; the heavy ore screening table 4 is detachably connected to the second inner opening on both sides by bolts; both the light ore screening table 3 and the heavy ore screening table 4 are provided with various specifications, and the screen hole sizes corresponding to different specifications are different. The corresponding light ore screening table 3 and heavy ore screening table 4 can be selected and installed according to the particle size that needs to be screened.

[0033] The method of use or working principle of this utility model is as follows:

[0034] During the separation process, mineral materials enter the gravity separation bed 2 from the mineral feed side 22. Under the action of the positive X-axis flow of water and the reciprocating vibration of the shaking table 1, they are separated into heavy minerals and light minerals by the separating bars 21. The heavy minerals enter the heavy mineral screening bed 4 from the first heavy mineral discharge end 25 through the first channel 24, while the light minerals cross the separating bars 21 and enter the light mineral screening bed 3 from the light mineral discharge side 23. The heavy minerals are vibrated and screened on the heavy mineral screening bed 4. Fine heavy minerals pass through the screen holes on the second bed bar 41 and fall below the heavy mineral screening bed 4, while coarse heavy minerals... The material is discharged from the coarse heavy mineral discharge end 42 along the second bed bar 41; the light mineral is vibrated and screened on the light mineral screening bed 3; the fine light mineral falls below the light mineral screening bed 3 through the screen holes on the inner wall of the groove 32 and the top surface of the first bed bar 31; the coarse light mineral passes over the first bed bar 31 and is discharged from the coarse light mineral discharge side 35, thereby obtaining four products: fine heavy mineral, coarse heavy mineral, fine light mineral and coarse light mineral. At the same time, the residual heavy mineral mixed in the light mineral can enter the heavy mineral screening bed 4 from the second heavy mineral discharge end 34 through the second channel 33.

[0035] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
