Description

Technical Field

[0001] This invention relates to the field of mineral processing equipment technology, and more specifically, to a belt shaking table conveyor for preventing fine powder dispersion and settling. Background Technology

[0002] Shaking tables are commonly used equipment in the field of mineral sorting. By reciprocating the vibration of the bed surface, the difference in specific gravity of mineral particles of different densities causes heavy mineral particles to sink to the bottom and light mineral particles to float to the top, thus achieving stratification of mineral materials according to specific gravity. At the same time, the directional water flow washes away the lighter mineral materials at the top, leaving the heavier target mineral materials at the bottom, thus completing the separation and screening of mineral materials.

[0003] Chinese invention patent CN120586991A discloses a novel shaking table structure with good recycling effect. During the screening process, the drive motor can be started to make the rotating shaft drive the drive wheel to rotate, so that the drive wheel and the driven wheel cooperate to drive the conveyor belt to move, and the conveyor belt drives the mineral to move slowly to the left, thereby improving the screening efficiency of the mineral.

[0004] However, the smooth surface of the conveyor belt lacks effective restraint on the ore. Before the vibration has fully achieved stratification of the ore, the scouring water flow can directly impact the surface of the ore, washing away the heavy ore particles that have not yet settled at the top, resulting in waste of the ore. Summary of the Invention

[0005] This invention provides a belt shaking table conveyor belt ore settling device to prevent fine powder dispersion. It forms a concave settling zone on the conveyor belt through the reserved notch of the pallet, realizing the pre-deposition and stratification of the ore. In conjunction with the baffle of the feed box, it reduces the impact force of water flow and ore, and avoids the dispersion of fine powder and heavy mineral particles, thereby solving the problems of heavy mineral particle loss and low sorting accuracy mentioned in the background art.

[0006] To achieve the above objectives, the belt shaking table conveyor for preventing fine powder dispersion includes a base frame, a main frame movably mounted on the top of the base frame, a conveyor belt installed inside the main frame via a power mechanism, the power mechanism driving the conveyor belt to rotate cyclically, and a recovery section installed at the rear end of the main frame for classifying and recovering different mineral materials.

[0007] Based on the above, a support plate is fixedly installed inside the main frame. The support plate provides support for the conveyor belt to ensure that it does not collapse when carrying ore. The support plate has a reserved notch. When the reserved notch acts on the conveyor belt, it forms a concave settling zone at the corresponding position of the conveyor belt. In use, the ore is directly discharged into the settling zone. The concave structure forms a physical constraint to prevent it from being directly washed away by the water flow. At the same time, it quickly separates into layers under the action of vibration.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting up a settling zone with reserved gaps, the concave structure physically binds the ore, allowing the ore to be pre-layered within the settling zone. This prevents unlayered heavy ore particles from being washed away by the water flow. At the same time, the settling zone, in conjunction with the vibration and rotation of the conveyor belt, accelerates the sinking of heavy ore particles, improves the stratification efficiency, and solves the problems of heavy ore particle loss and resource waste in existing technologies.

[0009] 2. By setting a baffle on one side of the feeding box, the slurry is decelerated by hitting the baffle after being discharged through the through hole, and then falls smoothly into the settling area. This avoids the slurry directly impacting the conveyor belt, which would cause the ore to splash and disperse, protects the heavy ore particles from being washed away, and makes the ore distribution more uniform.

[0012] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0013] Because the conveyor belt of the existing belt shaker has a smooth surface and lacks a mineral binding structure, when the vibration does not completely separate the minerals, the water flow can easily disperse and carry away the heavy mineral particles, resulting in resource waste, low sorting accuracy, and increased production costs.

[0014] Therefore, in view of the above-mentioned problems, the present invention discloses a belt shaking table conveyor for preventing fine powder dispersion, as shown in the reference. Figure 1 As shown, the system includes a base frame 1. Two support slides 11 are fixedly mounted on the top of the base frame 1 (the support slides 11 have the same structure as those in the existing patent publication CN120550921A, so they will not be described in detail here). A main frame 2 is movably mounted on the top of the two support slides 11. The main frame 2 can reciprocate back and forth along the support slides 11. A conveyor belt 3 is installed inside the main frame 2 via a power mechanism. The power mechanism includes a motor, a drive roller, and a driven roller. The motor drives the drive roller to rotate, which in turn drives the conveyor belt 3 to rotate. The conveyor belt 3 is made of rubber with anti-slip textures on its surface to enhance friction with the ore. A feeding box 5 and a clean water trough 6 are fixedly mounted on one side of the top of the main frame 2. The feeding box 5 is located at the front end of the clean water trough 6. The feeding box 5 and the clean water trough 6 are connected... The water troughs 6 are all located on top of the conveyor belt 3. The top front end of the feeding box 5 is fixedly connected to the feeding funnel 51. The feeding funnel 51 has a conical structure, which facilitates the centralized transportation of mineral materials. The top of the feeding funnel 51 and the clear water trough 6 are both fixedly installed with water taps 7. The water taps 7 on the top of the feeding funnel 51 are used to disperse the mineral materials and guide them into the feeding box 5. The water taps 7 on the top of the clear water trough 6 are used to provide screening water flow. The main frame 2 is fixedly installed on the side away from the feeding box 5 and the clear water trough 6 with a waste trough 8. The waste trough 8 has an inclined structure and is used for the discharge and collection of light waste materials. The front end of the base frame 1 is installed with a transmission assembly 10 (the transmission assembly 10 has the same structure as the transmission assembly in the existing patent publication number CN120586991A, so it will not be described in detail here).

[0015] refer to Figure 2 As shown, during use, the power mechanism drives the conveyor belt 3 to rotate, and at the same time the transmission component 10 is activated. With the support of the support slide 11, the main frame 2 is driven to move back and forth, forming a vibration layered power.

[0016] Next, refer to Figure 3As indicated by the solid arrow, the two water taps 7 inject water into the feed box 5 and the clear water tank 6 respectively. The workers put the ore into the feed funnel 51, and the water flow from the water tap 7a disperses the ore into the feed box 5. Then, the ore is discharged from the feed box 5 to the conveyor belt 3, so that the ore is evenly distributed on the conveyor belt 3. At the same time, the water flow from the water tap 7b impacts the clear water tank 6 and is guided by the clear water tank 6 to be directed out from the side of the conveyor belt 3, forming a flushing area at the rear end of the conveyor belt 3. At this time, the vibration of the transmission component 10 causes the ore at the top of the conveyor belt 3 to be stratified according to the difference in gravity, with heavier ore particles at the bottom and lighter ore particles at the top. With the impact of the side water flow, the lighter waste material in the ore is flushed towards the waste trough 8, while the heavier ore material stays on the side close to the feed box 5 and the clear water tank 6, thus achieving screening.

[0017] Although ore screening can be achieved through vibration and side water flow impact, before the vibration has completely separated the ore into layers, the water flow can easily wash some heavy ore particles from the top into the waste trough 8, resulting in waste.

[0018] Therefore, refer to Figure 4 As shown, a support plate 4 is fixedly installed inside the main frame 2. The support plate 4 is located inside the conveyor belt 3 and is used to support the upper end of the conveyor belt 3 to prevent the conveyor belt 3 from sinking and deforming due to the weight of the ore.

[0019] The pallet 4 is welded from multiple square tubes. The overall size of the pallet 4 is the same as the upper end of the conveyor belt 3, so that the conveyor belt 3 has sufficient support to carry the ore. One of the square tubes on the side of the pallet 4 near the feeding box 5 is bent and welded to fix it, so that the pallet 4 forms a rectangular reserved notch 41 at the position of the feeding box 5 discharge area. When this reserved notch 41 is applied to the conveyor belt 3, the conveyor belt 3 loses the support of the square tube and forms a concave sinking area 31 under its own weight and the weight of the ore. The sinking area 31 corresponds to the discharge area of ​​the feeding box 5, ensuring that the ore falls directly into the sinking area 31.

[0020] For details, please refer to the following: Figure 5 As shown, during use, the ore is discharged directly from the discharge port of the feeding box 5 into the settling zone 31. The concave structure of the settling zone 31 forms a physical barrier, preventing the ore from being directly dispersed by the water flow. With the rotation of the conveyor belt 3 and the vibration of the main frame 2, the ore is fully tumbled in the settling zone 31. Heavy ore particles quickly sink to the bottom of the settling zone 31, while light ore particles float on the upper layer, achieving pre-separation and laying the foundation for subsequent screening.

[0021] Next, the specific structure of the feeding box 5 and the clear water tank 6 will be disclosed. Please refer to [link / reference]. Figure 6 As shown, the feed box 5 has multiple through holes 52 on the side plate near the waste trough 8 to allow the ore and water to be discharged evenly. The feed funnel 51 has a baffle 53 fixedly connected to the side plate near the through holes 52 by welding. The baffle 53 is located outside the through holes 52.

[0022] For details, please refer to the following: Figure 5 As shown, after the water flows out from the faucet 7a, it falls into the feed box 5 and mixes with the ore to form a slurry. The slurry is evenly discharged through multiple through holes 52. After being discharged, it impacts the inclined baffle 53. The baffle 53 can reduce the impact speed of the slurry and effectively reduce the impact force. By setting the baffle 53, the slurry can be prevented from directly impacting the conveyor belt 3, causing the ore to splash, and ensuring that the ore falls smoothly into the settling area 31.

[0023] Multiple water guide blocks 61 are bolted to the top of the clear water tank 6. Each water guide block 61 is a rhomboid plastic block, with gaps between adjacent blocks. Refer to [reference / reference / etc.] when using. Figure 7 As shown, the water discharged from the faucet 7b falls into the clear water tank 6. After being guided by the tank body, it is evenly discharged into the conveyor belt 3 through the gaps between multiple water guide blocks 61, forming a stable flushing water flow. This flow impacts the pre-layered mineral material on the conveyor belt 3, and pushes the light mineral material floating on the upper layer towards the waste trough 8.

[0024] The water guide block 61 is bolted to the top of the clear water tank 6, with the bolt passing through the middle of the water guide block 61, allowing the water guide block 61 to rotate around the bolt. Figure 7 As shown, workers can manually rotate the water guide block 61 according to the particle size and stratification of the ore to adjust the gap between adjacent water guide blocks 61. The larger the gap, the more water flows through and the stronger the scouring force. This allows control over the size and speed of the water flow discharged from the clear water tank 6, preventing the water flow from being too large to disperse heavy ore particles or too small to effectively discharge light ore.

[0025] For detailed screening procedures, please refer to [link / reference]. Figure 8 As shown: The ore is dispersed into the feed box 5 by the water tap 7a. The ore mixes with the water to form a slurry, which is discharged through the through hole 52 and decelerated by hitting the baffle 53. It is then smoothly discharged into the settling zone 31 of the conveyor belt 3. At the same time, the main frame 2 vibrates back and forth, and the ore is quickly stratified in the settling zone 31, causing heavy ore particles to sink and light ore particles to float. The conveyor belt 3 drives the stratified ore towards the clear water tank 6. The water flow from the water tap 7b is adjusted by the water guide block 61 and evenly washes the surface of the ore. The light ore floating on the upper layer is flushed towards the waste tank 8, while the heavy ore particles, including fine powder heavy ore particles, that sink to the lower layer continue to move with the conveyor belt 3, achieving precise screening.

[0026] After the ore is screened on conveyor belt 3, different types of ore need to be classified and collected. Therefore, a recycling unit 9 is installed at the rear end of the main frame 2. (See details...) Figure 9-10 As shown.

[0027] The recycling unit 9 includes a support frame 91 that is bolted to the rear end of the main frame 2. An inclined plate is fixedly installed inside the support frame 91 by welding to facilitate the sliding of the ore. Three discharge holes 911 are opened at the rear end of the support frame 91 for discharging ore of different particle sizes or specific gravities. A water pipe 92 is fixedly installed at the upper end of the support frame 91. The water pipe 92 is connected to an external water source. The water pipe 92 is located at the rear end of the conveyor belt 3. Multiple water spray holes 921 are opened on the outer wall of the water pipe 92. The water spray holes 921 face the surface of the conveyor belt 3 to ensure that the water flow can effectively wash away the ore residue on the surface of the conveyor belt 3.

[0028] In use, clean water is introduced into the water pipe 92, and the water flow is sprayed out from multiple water spray holes 921 to evenly wash the surface of the conveyor belt 3, washing away the heavy mineral materials, including fine powder and heavy mineral particles, attached to the conveyor belt. The mineral materials fall onto the inclined plate and slide down the inclined surface. According to the differences in particle size and specific gravity of the mineral materials, the mineral materials in different areas are discharged from the corresponding discharge holes 911, realizing the classification and recycling of different types of mineral materials and avoiding the mixing of mineral materials.

[0029] To enable the autonomous selection of specific types of minerals for collection, refer to Figure 9-10 As shown, a support rod 93 is fixedly installed on the top of the inclined plate by welding. A receiving funnel 94 is slidably installed on the support rod 93. The receiving funnel 94 is located between the inclined plate and the conveyor belt 3, and the bottom outlet of the receiving funnel 94 can be connected to a collection bag or a pipe.

[0030] When in use, staff can slide the receiving funnel 94 to the corresponding position on the inclined plate, such as the middle layer area, to collect the target heavy mineral material as needed.

[0031] Working principle: Start the power mechanism and transmission components 10, the conveyor belt 3 rotates in a cycle, the main frame 2 vibrates back and forth, the water tap 7 injects water, the ore is put into the feeding hopper 51, after being dispersed by the water flow, it mixes with the water, is discharged through the through hole 52 of the discharge box 5 and hits the baffle 53 to slow down, and falls smoothly into the settling area 31 of the conveyor belt 3.

[0032] The ore is vibrated and stratified in the settling zone 31, causing heavy ore particles to sink and light ore particles to float. The conveyor belt 3 moves the ore to the bottom of the clear water tank 6. The water flow regulated by the water guide block 61 washes the light ore particles to the waste tank 8. The heavy ore particles move to the rear end with the conveyor belt 3. The water spray hole 921 of the water pipe 92 sprays water to flush them to the inclined plate. The ore is then classified and recycled through the discharge hole 911, or the target ore is selectively collected through the receiving funnel 94.
