Description

Technical Field

[0001] This invention relates to the field of spiral chute separation, and particularly to a spiral chute ore separation device. Background Technology

[0002] A spiral sluice mainly consists of a spiral sluice, a feeding device, and a discharging device. The spiral sluice is its core component, typically spiraling downwards. The sluice body is usually made of materials such as fiberglass, because fiberglass has the advantages of being lightweight and corrosion-resistant, ensuring the long-term stable operation of the spiral sluice in harsh slurry environments. When the slurry enters the spiral sluice, centrifugal force is generated due to the rotating structure of the sluice. Under the combined action of centrifugal force, gravity, friction, and the flow force of the slurry, mineral particles of different densities exhibit different trajectories.

[0003] Generally, denser mineral particles tend to gravitate towards the inner edge of the spiral groove, while less dense mineral particles tend to gravitate towards the outer edge. This is because the combined centrifugal force and gravity acting on denser particles are more directed towards the bottom and inner side of the spiral groove, while the combined force acting on less dense particles is more directed towards the outer side and top. A similar technique is disclosed in prior art, such as patent number CN109731672B.

[0004] In the mineral processing process, the discharge of slurry generally relies solely on the direct discharge from the slurry outlet pipe, and the discharge is relatively concentrated. Some spiral troughs may undergo simple treatment in the initial stage, but their complex structure and uneven discharge in multiple directions, as well as their lack of direct coordination with the impact potential energy generated by the slurry outlet pipe, result in poor looseness and easy agglomeration when the minerals fall onto the spiral trough, leading to excessively low sorting efficiency during spiral descent. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a spiral chute ore separation device, which mainly solves the problem that the discharge of mineral slurry at the head end of the spiral chute is not uniform and easily leads to the agglomeration and accumulation of mineral slurry during the flow process.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] This invention provides a spiral chute ore separation device, comprising a main body, a support frame on the outside of the main body, a spiral chute overlapping the inner side of the support frame, an auxiliary fixing rod installed in the middle of the spiral chute, the rod extending upward to the upper end of the support frame, and a mud bucket installed at the top of the rod, with a mud outlet pipe provided on the side of the mud bucket, a sealing plate installed at the upper end of the spiral chute, a fitting plate installed on the surface of the sealing plate, a drive motor and an adjustment component installed on the rear surface of the fitting plate, and a swing plate installed on the front surface of the fitting plate. The swing plate is a triangular grid evenly arranged, and the drive motor is used to drive the adjustment component to make the swing plate swing left and right against the bottom end of the spiral chute.

[0008] Preferably, the adjusting assembly includes a telescopic component and a fixing component, wherein the telescopic component includes: a slide bar, which is disposed on the upper and lower parts of the inner side of the telescopic component; a rack, which is disposed on the middle part of the inner side of the telescopic component; the fixing component includes: a slide groove, which is disposed on the upper and lower parts of the fixing component; a gear, which is disposed on the middle part of the fixing component; a fixing rod, which is installed on the axial direction of the gear and is respectively connected to the side surface of the slide groove in the upper and lower parts; a connecting rod, which is respectively connected to the side surface of the swing plate and the gear; the surface of the fitting plate is provided with a through hole, which is used for the connecting rod to connect to the swing plate, and the sides of the through hole and the connecting rod have cavities.

[0009] Preferably, the drive motor and the telescopic component are connected by a transmission, and the rack and gear are meshed.

[0010] Preferably, the surface of the connecting rod is fitted with a corrugated tube, which is installed on the rear end of the swing plate and the surface of the fitting plate, respectively, and the length of the swing plate is not less than 15cm.

[0011] Preferably, concave triangular guide blocks are provided at equal intervals along the edge of the spiral groove, and a spiral line is provided at the bottom of the spiral groove.

[0012] Preferably, the spiral lines are disposed on the surface of the spiral groove and are evenly spaced. The spiral lines are composed of synapses arranged in a spindle shape. The protrusions at the top of the synapses are off-center from the axis, and the angle between the protrusions and the spiral groove is greater than 90 degrees.

[0013] Preferably, a solar panel and a battery are mounted on the outer surface of the support frame. The battery includes a voltage regulator, a control switch, and a wireless connection module, and is used to supply power to the drive motor.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This invention incorporates a closed plate and a fitting plate in the initial stage of the spiral groove. The drive motor and adjustment components on the fitting plate enable the swing plate to move horizontally. After the mineral slurry falls from the slurry outlet pipe, it can be evenly dispersed into the spiral space in different directions. This ensures that the minerals are evenly dispersed, and the shape of the swing plate can also cooperate with the slurry outlet pipe to form a flow guiding effect, completing the flushing operation of the spiral groove in different directions and reducing the accumulation effect of the mineral slurry.

[0016] 2: The present invention further improves the spiral by changing the strip-shaped spiral into a combination of multiple synapses, so that the gap between the synapses can better adapt to the passage of mineral sand, and forms a differential velocity between the upper, middle and lower layers based on the structure of the synapses themselves, which increases the overall screening efficiency of the device while guiding the mineral flow.

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example 1

[0029] like Figure 1 , 3 As shown in Figure 6, this invention provides a spiral chute ore separation device. The main body 1 of the device is provided with a support frame on the outside, and a spiral chute 2 is connected to the inside of the support frame. An auxiliary fixing rod is installed in the middle of the spiral chute 2. The rod extends upward to the upper end of the support frame, and a mud tank 101 is installed on the top of the rod. A slurry outlet pipe 102 is provided on the side of the mud tank 101. In the conventional process, the well-stirred ore slurry is injected into the mud tank 101 by a mud pump. The ore slurry is then continuously poured into the starting end of the spiral chute 2 from the mud tank 101 based on the slurry outlet pipe 102. The ore slurry is divided into different concentrates, intermediates, and tailings along the spiral chute 2 to the tail end, forming the conventional function of ore primary treatment.

[0030] A sealing plate 201 is installed at the upper end of the spiral groove 2. A fitting plate 3 is installed on the surface of the sealing plate 201. A drive motor 301 and an adjustment component 302 are installed on the rear surface of the fitting plate 3. A swing plate 303 is installed on the front surface of the fitting plate 3. The swing plate 303 is a triangular grid with equal spacing. Under the action of the drive motor 301, the adjustment component 302 is driven to make the swing plate 303 swing left and right against the bottom of the spiral groove 2. This allows the mud discharge from the lower part of the discharge pipe 102 to be evenly distributed on the surface of the spiral groove 2 with the swing plate 303. This avoids the mud and sand inside the mud tank 101 from agglomerating or being moved with the water flow on the surface of the spiral groove 2 due to agglomeration or concentrated discharge, which would cause blockage at the edge of the spiral. After swinging, the mud can be better evenly dispersed left and right.

[0031] Furthermore, the adjustment component 302 includes a telescopic member 4 and a fixing member 5. The telescopic member 4 has a slide bar 401 and a rack 402 installed in the middle on the upper and lower parts of its inner side. The fixing member 5 has a slide groove 501 in the upper and lower parts and a gear 503 in the middle. The gear 503 extends axially with a fixing rod 502. The fixing rod 502 is connected to the slide groove 501 in the upper and lower parts respectively. The gear 503 extends with a connecting rod 505 connected to the swing plate 303. The connecting rod 505 passes through a through hole 504 on the surface of the mating plate 3. The through hole 504 and the side of the connecting rod 505 have narrow cavities.

[0032] The drive motor 301 and the telescopic component 4 are connected by a transmission. The rack 402 and the gears 503 are meshed, so that when the drive motor 301 extends and retracts, the rack 402 and multiple gears 503 mesh and transmit power. The swing plate 303 moves together with the gears 503 based on the connecting rod 505. When the drive motor 301 moves back and forth at a constant speed, the swing plate 303 will also swing at a constant speed.

[0033] To reduce slurry splashing and the impact of the blades on the transmission components, a bellows 506 is fitted onto the surface of the connecting rod 505. The bellows 506 is installed on the rear end of the swing plate 303 and the surface of the fitting plate 3, respectively. The length of the swing plate 303 is not less than 15cm. This allows the slurry pipe 102 to be moved away from the closed plate 201 at the projection of the spiral groove 2, while the extended length of the swing plate 303 can disperse the slurry at a uniform speed to different directions at the initial point over a wider range.

[0034] Specifically, when the slurry falls from the outlet pipe 102, the drive motor 301 is activated, causing the telescopic component 4 to move back and forth on the fixed component 5. The rack 402 also drives the gear 503 to mesh and transmit power to the swing plate 303, allowing the swing plate 303 to continuously disperse the mineral slurry in different directions. After the grid-shaped swing plate 303 is extended, it can not only achieve the diversion function, but also allow the outlet pipe 102 to move away from the end of the sealing plate 201, while allowing the swing plate 303 to swing over a wider range on the spiral groove 2. Even if there are clumps of mineral slurry, the continuous swing of the swing plate 303 will break them up and wash them away with the slurry that falls from the outlet pipe 102, avoiding blockage or clumps of mineral slurry in the initial part of the spiral groove 2. The designed sealing plate 201 can also reduce the splashing of mineral slurry.

[0035] Its structure is simple and easy to maintain. The whole is modularly designed. Different modules can be disassembled separately when necessary. It is generally set at the initial end of the spiral groove 2. When needed, solar panels and batteries can be installed on the outside of the support frame to continuously power the drive motor 301. Since the drive motor 301 only needs to have an on and off function, when the drive motor 301 or the battery includes a wireless module, no complicated control is required. The staff can operate remotely by simply connecting to the wireless module.

[0036] Example 2

[0037] The difference from Example 1 is that, as Figure 2 , 7 As shown in Figure 8, in order to reduce blockage on the spiral and increase the flow rate of the spiral, concave triangular guide blocks 202 are set at equal intervals along the edge of the spiral groove 2, and a spiral line 203 is set at the bottom of the spiral groove 2, so that the slurry flowing from top to bottom to the edge can return to the area around the rod along with the guide blocks 202 and the spiral line 203, and the slurry accumulated in the spiral groove 2 is returned to the middle for screening again.

[0038] The spiral 203 is disposed on the surface of the spiral groove 2, and the spiral 203 is disposed at equal intervals. The spiral 203 is composed of a series of synapses 204. The synapses 204 have a spindle-shaped structure. The protrusion 205 at the top of the synapse 204 is off-center, and the angle between the protrusion 205 and the spiral groove 2 is greater than 90 degrees.

[0039] Specifically, the arrangement shape of the spiral 203 itself is as follows: Figure 1 As shown, the concave triangular guide block 202 can more efficiently gather the slurry. Furthermore, in order to reduce the retention of mineral sand slurry on the spiral 203, the spiral 203 is further improved into a structure of multiple independent synapses 204. Due to gravity, heavier mineral sand can pass directly through the gaps between the synapses 204, while lighter slurry and debris can pass through the upper part of the synapses 204. Moreover, the structure of the synapses 204 is a hydrophobic structure that resembles a lotus leaf, which also allows dust and silt to pass through quickly without contacting the mineral sand at the bottom, increasing the stratification effect of the water flow.

[0040] In actual working environments, compared with conventional spiral 203, the improved spiral 203 using the structure of this invention increases the screening efficiency of mineral sand by 5% to 10%. This is because when finer particles of mineral sand descend continuously over a long distance in a spiral, they pass through the gaps of synapses 204. Larger particles of mineral sand pass through the lower large gap, while finer particles pass through the middle small gap. The uppermost wide gap mainly allows lighter silt to pass through. The structure of synapses 204, based on the lotus leaf effect, stratifies the fine particles of mineral sand and the lighter silt, causing a speed difference between the upper and lower parts when the water flows with the spiral 203. A large amount of mineral sand can be concentrated near the inner side, while silt is located on the outermost side.

[0041] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
