[0001] This utility model relates to the field of mineral particle screening, and specifically to a mineral particle screening device. Background Technology

[0002] Minerals are natural compounds with a specific chemical composition, possessing stable phase interfaces and crystallization habits. The internal crystallization habit determines the crystal form and symmetry of a mineral; the nature of its chemical bonds determines its hardness, luster, and electrical conductivity; and its chemical composition and the tightness of its bonding determine its color and specific gravity, among other things.

[0003] In the field of mineral processing, mineral particle screening is a crucial step, as its effectiveness directly affects the quality and efficiency of subsequent mineral processing.

[0004] Existing technologies typically employ a horizontally rotating drum with through holes. However, this method causes mineral particles to fall from the top to the bottom of the drum and splash during rotation, which can damage the drum, affect its service life, and increase production safety hazards.

The rod gear 132 is wheel-connected to the motor gear 133. A lifting motor 134 is connected to the motor gear 133 and is connected to the gear fixing frame 131.

[0050] In some embodiments, the lifting rod 12 is connected from top to bottom to an upper limit block 121, a middle limit block 122, and a lower limit block 123. The rotating mounting bracket 21 is slidably connected to the lifting rod 12, and the rotating mounting bracket 21 is located between the upper limit block 121 and the middle limit block 122.

[0051] In this embodiment, the lifting base 11 is first placed stably on the working surface to ensure it is level and stable. The lifting rod 12 is installed on the lifting base 11 via a sliding connection, ensuring that the lifting rod 12 can slide smoothly up and down within the lifting base 11 without any jamming.

The lifting motor 134 is installed on the gear fixing frame 131, and its output shaft is connected to the motor gear 133 to ensure stable power transmission. At the same time, the rod gear 132 is threadedly connected to the lifting rod 12, so that the rotation of the rod gear 132 can drive the lifting rod 12 to move up and down. The upper limit block 121, the middle limit block 122, and the lower limit block 123 are installed on the lifting rod 12 in a top-to-bottom order, ensuring that the limit blocks are accurately positioned and can effectively limit the movement range of the rotating mounting frame 21.

[0052] In some embodiments, a cylinder gear 32 is connected to the screening cylinder 31, and the rotating assembly 2 includes a main drive component 22 connected to one of the rotating mounting frames 21. The main drive component 22 includes a rotating motor 221 connected to the rotating mounting frame 21 and a rotating gear 222 connected to the rotating motor 221.

[0053] In some embodiments, a rotating ring frame 33 is connected to the screening cylinder 31, and rotating tracks 34 are provided on both the upper and lower sides of the rotating ring frame 33. The rotating assembly 2 includes a positioning wheel 23 rotatably connected to the rotating mounting frame 21, and the positioning wheel 23 is rotatably connected to the rotating track 34.

[0054] In some embodiments, a plurality of screening holes 311 are provided below the screening cylinder 31, and the diameter of the screening holes 311 is the same along the center line of the arc.

[0055] In some embodiments, the bottom of the screening cylinder 31 is connected to a baffle moving seat 312, and a baffle 35 is movably connected to the baffle moving seat 312. The baffle 35 is used to block the screening hole 311 at the center line of the arc when it moves to the position of the screening hole 311; when it moves away from the position of the screening hole 311, the screening hole 311 can screen particles of the corresponding pore size.

[0056] In this embodiment, the rotating mounting bracket 21 is slidably mounted on the lifting rod 12, positioned between the upper limit block 121 and the middle limit block 122, ensuring that the rotating mounting bracket 21 can slide flexibly on the lifting rod 12. A cylinder gear 32 is mounted on the screening cylinder 31, rotating synchronously with it. The rotating motor 221 in the main drive unit 22 is mounted on the rotating mounting bracket 21, and the rotating gear 222 is mounted on the output shaft of the rotating motor 221. The position is adjusted to ensure accurate meshing between the rotating gear 222 and the cylinder gear 32. A rotating ring frame 33 is mounted on the screening cylinder 31, ensuring it is securely installed and accurately positioned. Rotating tracks 34 are mounted on the upper and lower sides of the rotating ring frame 33, and the positioning wheel 23 is slidably mounted on the rotating mounting bracket 21, ensuring good cooperation between the positioning wheel 23 and the rotating track 34, achieving stable positioning of the screening cylinder 31 during rotation. A baffle moving seat 312 is installed at the bottom of the screening cylinder 31, and a baffle 35 is installed on the baffle moving seat 312 to ensure that the baffle 35 can move smoothly on the baffle moving seat 312. In addition, the screening holes 311 arranged along the center line of the arc have the same diameter, which can screen mineral particles of the same diameter. It should be noted that the diameter of the screening holes 311 arranged along other arc center lines can be adapted according to the requirements and should be within the protection scope of this application. The two ends of the baffle 35 are slidably connected to the baffle moving seat 312, and the baffle 35 can rotate under the restriction of the baffle moving seat 312, thereby closing the screening holes 311 arranged along the center line of the arc to meet the screening requirements.

[0057] In some embodiments, the discharge buffer 4 includes a buffer cylinder 41 connected below the screening cylinder 31, a cover 42 connected below the buffer cylinder 41, a rotating rod 43 rotatably connected to the cover 42, a buffer cover 44 connected to the rotating rod 43, and a return spring 45 provided on the rotating rod 43. One end of the return spring 45 is connected to the cover 42, and the other end of the return spring 45 is connected to the rotating rod 43.

[0058] In this embodiment, the screened mineral particles enter the buffer cylinder 41 from the lower end of the screening cylinder 31. When the mineral particles impact the buffer cover 44, the buffer cover 44 rotates around the rotating rod 43, simultaneously compressing the return spring 45, thus buffering the impact and reducing the impact force of the mineral particles to prevent material splashing. After the material passes through, the buffer cover 44 returns to its original position under the action of the return spring 45, continuing to buffer subsequent materials, and finally the material is smoothly discharged from the lower end of the buffer cylinder 41.

[0059] In some embodiments, a cover 36 is connected above the screening cylinder 31, the cover 36 has a feed hole 361, a feeding motor 37 is connected to the middle of the cover 36, and a feeding rod 38 is connected to the rotating end of the feeding motor 37.

[0060] In this embodiment, the cover 36 is installed above the screening cylinder 31 to ensure a good seal. A feed hole 361 is provided on the cover 36, and a feeding motor 37 is installed in the middle of the cover 36. A feeding rod 38 is installed on the rotating end of the feeding motor 37 to ensure that the feeding motor 37 can drive the feeding rod 38 to rotate normally, so as to move the mineral particles and prevent them from accumulating.

[0061] Example 1:

[0062] Based on actual production needs, the lifting motor 134 is activated. The rotation of the lifting motor 134 drives the motor gear 133 to rotate, which in turn drives the rod gear 132 to rotate. Since the rod gear 132 is threadedly connected to the lifting rod 12, its rotation causes the lifting rod 12 to move up and down within the lifting base 11. When the lifting rod 12 moves, the rotating mounting bracket 21 moves along with it. Simultaneously, the upper spring 14 and lower spring 15 provide cushioning and auxiliary stabilization, ensuring smoother movement of the rotating mounting bracket 21 during its movement.

[0063] Example 2:

[0064] The mineral particles to be screened are poured into the screening cylinder 31 through the feed hole 361. The feeding motor 37 is started, driving the feeding rod 38 to rotate, which evenly distributes the mineral particles within the screening cylinder 31, preventing material accumulation. The rotating motor 221 is started, driving the rotating gear 222 to rotate. The rotating gear 222 meshes with the cylinder gear 32, driving the screening cylinder 31 to rotate. During the rotation of the screening cylinder 31, the positioning wheel 23 rolls within the rotating track 34, ensuring smooth rotation. As the screening cylinder 31 rotates, mineral particles of different sizes are screened through the screening holes 311 under the action of centrifugal force and gravity. If it is necessary to adjust the screening particle size, this can be achieved by moving the baffle 35. When the baffle 35 moves on the baffle moving seat 312 to the position of the screening hole 311, it can block the screening hole 311 at the corresponding arc centerline position, thereby changing the particle size of the mineral particles that can pass through; when the baffle 35 moves away from the position of the screening hole 311, the screening hole 311 works normally and screens particles of the corresponding aperture size.

[0065] Example 3:

[0066] The screened mineral particles enter the buffer cylinder 41 from the lower end of the screening cylinder 31. When the mineral particles impact the buffer cover 44, the buffer cover 44 rotates around the rotating rod 43, simultaneously compressing the return spring 45, thus buffering the impact and reducing the material splashing. After the material passes through, the buffer cover 44 returns to its original position under the action of the return spring 45, continuing to buffer subsequent materials, and finally the material is smoothly discharged from the lower end of the buffer cylinder 41.

[0067] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0068] The system includes at least three lifting support components. Through the coordinated operation of these components, the screening mechanism can be moved to oscillate on both sides, agitating the mineral particles and enabling the screening mechanism to process them. Each lifting support component is connected to a rotating mounting frame, which supports the screening mechanism. The rotating assembly allows the screening mechanism to rotate, improving the screening effect. A discharge buffer is connected to the lower end of the screening cylinder, which cushions the mineral particles output from the screening cylinder, ensuring a smooth entry into the collection chamber. This solution addresses the problem in existing technology where mineral particles fall from the top to the bottom of the rotating drum, causing splashing and damage, affecting the drum's lifespan, and increasing production safety hazards.
