Description

Technical Field

[0001] The invention relates to the field of spiral chute sorting, and in particular to a spiral chute ore separation device. Background Art

[0002] The spiral chute is mainly composed of a spiral chute, a feeding device, and a discharging device. The spiral chute is its core component, which generally spirals downward. The chute body is usually made of fiberglass and other materials because fiberglass has the advantages of light weight and corrosion resistance, which can ensure that the spiral chute can work stably for a long time in harsh slurry environments. When the slurry enters the spiral chute, centrifugal force is generated due to the rotating structure of the chute body. Mineral particles of different densities have different movement trajectories under the combined action of centrifugal force, gravity, friction, and slurry flow force.

[0003] Generally speaking, mineral particles with higher density tend to move toward the inner edge of the spiral groove, while mineral particles with lower density tend to move toward the outer edge of the spiral groove. This is because the combined force of centrifugal force and gravity on particles with higher density is more inclined toward the bottom and inner side of the spiral groove, while the combined force on particles with lower density is more inclined toward the outer side and upper side. For example, the prior art with patent number CN109731672B discloses a similar technology.

[0004] In the mineral processing process, the discharge of slurry generally only depends on the direct discharge of the slurry pipe, and the discharge is also relatively concentrated. Some spiral troughs will perform simple processing in the initial stage, but their structure is complex and they do not discharge evenly in multiple directions, nor do they directly cooperate with the impact potential energy generated by the slurry pipe. As a result, when the minerals fall onto the spiral trough, they are less loose and easily aggregated, making the sorting efficiency too low when the spiral falls. 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, which easily leads to the agglomeration and accumulation of mineral slurry during the flow process.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] The present invention provides a spiral chute ore separation device, comprising a device body, a support frame is provided on the outside of the device body, a spiral groove is overlapped on the inner side of the support frame, an auxiliary fixing rod is installed in the middle of the spiral groove, the rod extends upward to the upper end of the support frame, and a mud bucket is installed on the top of the rod, a slurry outlet pipe is provided on the side of the mud bucket, a closing plate is installed on the upper end of the spiral groove, a mosaic plate is installed on the surface of the closing plate, a driving motor and an adjusting component are installed on the rear surface of the mosaic plate, a swinging plate is installed on the front surface of the mosaic plate, the swinging plate is a triangular grid arranged at equal distances, and the driving motor is used to drive the adjusting component to make the swinging plate swing left and right in contact with the bottom end of the spiral groove.

[0008] Preferably, the adjustment assembly includes a telescopic part and a fixed part, wherein the telescopic part includes: a slide bar, which is arranged at the upper and lower parts of the inner side of the telescopic part; a rack, which is arranged at the middle part of the inner side of the telescopic part; the fixed part includes: a slide groove, which is arranged at the upper and lower parts of the fixed part; a gear, which is arranged in the middle part of the fixed part; a fixed rod, which is installed in the axial direction of the gear, and the fixed rod is respectively connected to the side surfaces of the slide groove of the upper and lower parts; a connecting rod, which is respectively connected to the side surfaces of the swing plate and the gear; a through hole is arranged on the surface of the engaging plate, and the through hole is used to connect the connecting rod to the swing plate, and a narrow cavity is left on the side of the through hole and the connecting rod.

[0009] Preferably, the driving motor and the telescopic member are in transmission connection, and the rack and the gear are meshingly arranged.

[0010] Preferably, a bellows is sleeved on the surface of the connecting rod, and the bellows is respectively installed on the rear end of the swing plate and the surface of the engaging plate, and the length of the swing plate is not less than 15 cm.

[0011] Preferably, guide blocks in the shape of concave triangles are arranged at equal distances on the edge of the spiral groove, and a spiral line is arranged at the bottom end of the spiral groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1: The present invention designs a closing plate and a mosaic plate in the initial stage of the spiral groove. The driving motor and the adjustment component on the mosaic plate enable the swing plate to move horizontally. After the mineral slurry falls from the slurry outlet pipe, it can be evenly dispersed in the spiral space in different directions. While the minerals are evenly dispersed, the shape of the swing plate can also cooperate with the slurry outlet pipe to form a diversion effect, complete the flushing operation on the spiral groove in different directions, and reduce the accumulation effect of the mineral slurry.

[0016] 2: The present invention further improves the spiral line by changing the strip-shaped spiral line into a combination of multiple synapses, so that the gaps between the synapses can better adapt to the passage of ore sand, and form a differential speed of the upper, middle and lower layers based on the structure of the synapse itself, while forming a diversion for the mineral, increasing the overall screening efficiency of the device.

DETAILED DESCRIPTION

[0027] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] Example 1

[0029] like Figure 1 , 3 -6, the present invention provides a spiral chute ore separation device, the device body 1 is provided with a support frame on the outside, a spiral groove 2 is overlapped on the inner side of the support frame, an auxiliary fixing rod is installed in the middle of the spiral groove 2, the rod extends upward to the upper end of the support frame, and a mud barrel 101 is installed on the top of the rod, and a slurry outlet pipe 102 is arranged on the side of the mud barrel 101. In the conventional process, the ore slurry that has been stirred evenly is injected into the mud barrel 101 through a mud pump, and then the mud barrel 101 continuously falls into the ore slurry at the starting end of the spiral groove 2 based on the slurry outlet pipe 102, and the ore slurry is divided into different fine, medium and tailings along the spiral groove 2 to the tail, forming a conventional effect of ore primary treatment;

[0030] A closing plate 201 is installed at the upper end of the spiral groove 2, and a mosaic plate 3 is installed on the surface of the closing plate 201. A driving motor 301 and an adjusting component 302 are installed on the rear surface of the mosaic plate 3. A swinging plate 303 is installed on the front surface of the mosaic plate 3. The swinging plate 303 is a triangular grid arranged at equal distances. Under the action of the driving motor 301, the adjusting component 302 is driven to make the swinging plate 303 swing left and right in contact with the bottom end of the spiral groove 2, so that the mud discharged from the lower part of the slurry discharge pipe 102 can be evenly distributed on the surface of the spiral groove 2 with the swinging plate 303, avoiding the mud and sand inside the mud barrel 101 from agglomerating or moving with the water flow on the surface of the spiral groove 2 after concentrated discharge, resulting in blockage of the edge of the entire spiral. After swinging, the mud can be better dispersed left and right.

[0031] Further, the adjustment assembly 302 includes a telescopic member 4 and a fixed member 5, wherein the upper and lower parts of the inner side of the telescopic member 4 are provided with a slide bar 401, a rack 402 installed in the middle, corresponding to the slide grooves 501 in the upper and lower parts of the fixed member 5, and the gear 503 in the middle, the gear 503 axially extends with a fixed rod 502, the fixed rod 502 is respectively connected to the slide grooves 501 in the upper and lower parts, 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 mosaic plate 3, and a narrow cavity is left on the side of the through hole 504 and the connecting rod 505;

[0032] There is a transmission connection between the driving motor 301 and the telescopic member 4, and the rack 402 and the gear 503 are meshingly arranged, so that when the driving motor 301 is extended and retracted forward and backward, the rack 402 and the multiple gears 503 are meshed and transmitted, and the swing plate 303 moves together with the gear 503 based on the connecting rod 505. When the driving motor 301 moves forward and backward at a constant speed, the swing plate 303 will also swing at a constant speed.

[0033] In order to reduce the splashing of slurry and the influence of the blades on the transmission components, a bellows 506 is sleeved on the surface of the connecting rod 505. The bellows 506 is respectively installed on the rear end of the swing plate 303 and the surface of the interlocking plate 3, and the length of the swing plate 303 is not less than 15 cm. In this way, the slurry outlet pipe 102 is kept away from the closing plate 201 at the projection of the spiral groove 2. The extended length of the swing plate 303 can disperse the slurry to different directions at a uniform speed in a larger range at the initial point.

[0034] Specifically, after the slurry drops from the slurry discharge pipe 102, the driving motor 301 is activated to drive the telescopic member 4 to continuously move back and forth on the fixed member 5, and the rack 402 will also drive the gear 503 to mesh and transmit to the swing plate 303, so that the swing plate 303 can continuously disperse the mineral slurry to different directions. Moreover, after the grid-shaped swing plate 303 is extended, it can not only achieve the diversion effect, but also make the slurry discharge pipe 102 away from one end of the closing plate 201, so that the swing plate 303 can swing on the spiral groove 2 over a larger range. Even if there is agglomerated mineral slurry, the continuous swinging of the swing plate 303 will break it up and wash it away with the slurry continuously falling from the slurry discharge pipe 102, thereby avoiding blockage or agglomeration of mineral slurry in the initial part of the spiral groove 2. The designed closing plate 201 can also reduce the splashing degree of the mineral slurry.

[0035] Its structure is simple and easy to maintain, and the overall design is modular. Different modules can be disassembled separately when necessary, and are generally arranged at the initial end of the spiral groove 2. When necessary, solar panels and batteries can be installed on the outside of the support frame to continuously power the drive motor 301. Because the drive motor 301 only needs the opening and closing functions, when the drive motor 301 or the battery includes a wireless module, there is no need for complex control. The staff can operate remotely by simply connecting to the wireless module.

[0036] Example 2

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

[0038] The spiral line 203 is arranged on the surface of the spiral groove 2, and the spiral line 203 is arranged at an equal distance. The spiral line 203 is composed of synapses 204 arranged in a spindle-shaped structure. The protrusion 205 on the top of the synapse 204 deviates from the axis, 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 line 203 itself is as follows Figure 1 As shown, the guide block 202 with the concave triangle can gather the slurry more efficiently. In addition, in order to reduce the retention of the ore slurry on the spiral line 203, the spiral line 203 is further improved to a structure of multiple independent synapses 204. Due to gravity factors, heavier ore can pass directly through the gaps between the synapses 204, while lighter mortar and debris can pass between the upper parts of the synapses 204. The structure of the synapses 204 is a hydrophobic structure imitating lotus leaves, which also allows dust and sediment to pass quickly without contacting the ore at the bottom, thereby increasing the stratification effect of the water flow up and down.

[0040] In an actual working environment, the screening efficiency of ore sand is increased by 5% to 10% when comparing the spiral line 203 improved by the structure of the present invention with the conventional spiral line 203. This is because when the finer particles of ore sand continuously descend in a long spiral, the large particles of ore sand pass through the large gap at the bottom, and the fine particles of ore sand pass through the small gap in the middle. The wide gap at the top mainly passes the lighter sediment. The structure of the synapse 204 separates the fine particles of ore sand and the lighter sediment according to the lotus leaf effect, so that when the water flow moves with the spiral line 203, a differential speed is formed up and down, and a large amount of ore sand can be concentrated near the inner side, while the sediment is located on the outermost side.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
