Description

Technical Field

[0001] The present invention relates to the technical field of metal ion extraction, in particular to an ore sample metal ion extraction device used for mineral resource exploration. Background Art

[0002] The content and type of metal ions in mineral resources directly affect their economic value, making exploration work using high-tech mineral geological exploration services extremely important. During the mineral resource exploration process, metal ions are often extracted from ore samples to ensure their mining value.

[0003] The existing extraction methods mostly use acid leaching, where the mined ore sample is placed in a container, and an acidic solution is added to react with the metal ions in the ore to dissolve the metal ions from the ore. In order to ensure the leaching rate of the metal ions, the ore sample needs to be crushed into small particles before acid leaching to ensure that the ore sample can fully contact the acidic solution. The existing crushing and acid leaching processes for ore samples are usually carried out independently, that is, crushing first and then acid leaching. However, the crushed ore sample is exposed to the air for a long time instead of being immediately pickled. There is a situation where some divalent iron ions are oxidized to trivalent iron ions, thereby reducing the leaching rate of divalent iron ions. In response to the above problems, there is a better solution in the prior art. After the ore sample is crushed by a crusher, the ore particles are directly transported to the acid leaching barrel by a conveyor for acid leaching. This can effectively avoid the situation where some divalent iron ions are oxidized to trivalent iron ions due to the long-term exposure of the material, thereby ensuring the leaching rate of divalent iron ions. However, the following problems still exist: since many tiny pores will appear on the surface of the ore after being crushed, in the process of acid leaching, the insoluble substances in the acidic solution tend to accumulate in the pores and cause "crusting" on the surface of the ore sample. In addition, the small-particle ore sample still has a relatively high hardness, which affects the penetration of the acidic solution into the interior of the ore particles, and still affects the leaching rate of divalent iron ions.

[0004] Therefore, in order to solve the above problems, a metal ion extraction device for ore samples used in mineral resource exploration is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide an ore sample metal ion extraction device for mineral resource exploration, which solves the problem that "crusting" is easily generated in the pores on the surface of ore particles during acid leaching, thereby affecting the leaching rate of divalent iron ions. By providing a rolling member and a rolling seat, the rolling member can be driven by a motor during the acid leaching process to continuously extend into the interior of the rolling seat to crush the ore particles, thereby destroying the "crust" on the surface of the ore particles. At the same time, the rolling seat can be driven to rotate under the action of a connecting component, and the acidic solution can be swirled, so that the ore particles falling from the rolling seat are swirled to the top of the rolling seat and then fall again. The ore particles falling into the rolling seat can be rolled multiple times, effectively avoiding the "crusting" phenomenon on the surface of the ore particles, thereby ensuring the leaching rate of divalent iron ions.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A metal ion extraction device for ore samples used in mineral resource exploration, comprising a barrel body and a barrel cover arranged on the barrel body, and also comprising a motor, a drive assembly, a rolling piece, a rolling seat support, a connecting assembly and a guide plate, wherein the motor is arranged on the barrel cover, and the drive assembly comprises a U-shaped plate, wherein the U-shaped plate is arranged at the output end of the motor, the rolling piece and the rolling seat are coaxially arranged inside the barrel body, and the rolling piece is arranged above the rolling seat and connected to the drive assembly, when the motor drives the U-shaped plate to rotate, the drive assembly drives the rolling piece to move back and forth up and down and rotate on its own, the support member is arranged inside the barrel body and connected to the rolling seat and the barrel body, the connecting assembly is arranged inside the barrel body and connects the U-shaped plate and the rolling seat, when the U-shaped plate rotates, the connecting assembly drives the rolling piece to rotate and causes the acidic solution inside the barrel body to form a vortex, the guide plate is arranged inside the barrel body and has multiple circular arrays, and the vortex drives the ore particles to flow through the guide plate to above the rolling seat and fall into the inside of the rolling seat.

[0008] Preferably, the drive assembly also includes a reciprocating screw, a slider, a hinge, a bevel gear and a bevel gear ring. The reciprocating screw is arranged through the U-shaped plate, the slider is sleeved on the reciprocating screw, the hinge is arranged inside the barrel body and the two ends are respectively hinged to the slider and the rolling member, the bevel gear is arranged at the end of the reciprocating screw, the bevel gear ring is coaxially arranged inside the barrel body and connected to the barrel cover, the bevel gear is meshed with the bevel gear ring, the rolling seat includes a base and a spoiler, a rolling groove is opened on the top of the base, and a discharge hole is opened at the bottom of the rolling groove. When the rolling member is squeezed with the ore particles in the rolling groove, the slider forms a speed difference between the rolling member and the base through the hinge.

[0009] By adopting the above scheme, the self-rotation and revolution of the reciprocating screw can be realized synchronously when the motor is working, and the rolling part can be driven to move back and forth in the vertical direction during the self-rotation of the reciprocating screw, thereby achieving the compression effect on the ore particles. In the process of the revolution of the reciprocating screw, the spoiler can be used to make the acidic solution achieve a swirling effect, and the ore particles in the acidic solution are guided toward the top of the base under the guiding action of the guide plate. Finally, after the ore particles fall into the inside of the rolling trough due to their own weight, they are re-compressed by the rolling part, thereby achieving the effective crushing of the "crust" on the surface of the ore particles, thereby ensuring the leaching rate of divalent iron ions in the ore particles.

[0010] Preferably, the connecting assembly includes a circular ring, a U-shaped rod, a limit rod, a limit block and an annular plate. The circular ring is sleeved on the reciprocating screw, the U-shaped rod is arranged on the annular plate, the limit rod is arranged on the base and passes through the U-shaped rod, the slider is sleeved on the limit rod, and the annular plate is sleeved on the base and connected to the limit block.

[0011] It can be seen that there are many ways to achieve the simultaneous rotation of the rolling part and movement in the axial direction, including but not limited to the use of the spiral structure inside the lipstick. Considering that the spiral structure inside the lipstick cannot rotate in one direction all the time, and the actual working process requires the rolling part to continue to rotate in one direction, thereby causing the acidic solution inside the barrel to produce a swirling effect, this solution is adopted. During the rotation of the reciprocating screw, the rolling part can be limited to prevent the rolling part from swinging away from the central axis of the barrel body. Therefore, during the rotation of the reciprocating screw, the reciprocating movement of the slider on the reciprocating screw can be used to drive the rolling part to move back and forth in the vertical direction, thereby squeezing the ore particles in the rolling trough, breaking the "crust" on the surface of the ore particles, and thus ensuring sufficient contact between the ore particles and the acidic solution; and in the process of the reciprocating screw rotating with the central axis of the barrel body as the rotation axis, the connection between the U-shaped rod and the limiting rod can be used to drive the base to rotate synchronously, thereby driving the spoiler at the bottom of the base to rotate, achieving a disturbing effect on the acidic solution inside the barrel body, causing a vortex in the acidic solution, and then the ore particles can be transported to facilitate repeated crushing of the "crust" on the surface of the ore particles, thereby ensuring the leaching rate of divalent iron ions in the ore particles during the acid leaching process.

[0012] Preferably, the hinged part includes a hinged rod, a hollow column, a fixed rod and a torsion spring, the upper end of the hinged rod is hinged to the slider, the hollow column is hinged to the lower end of the hinged rod, the fixed rod is arranged on the rolling part and is sleeved with the hollow column, the torsion spring is sleeved on the fixed rod, and the two ends are respectively connected to the inner walls of the fixed rod and the hollow column.

[0013] By adopting the above scheme, when the rolling part enters the interior of the rolling trough and contacts the ore particles and continues to rotate, the rotation of the rolling part will be restricted due to the friction between the rolling part and the ore particles. Under the action of the torsion spring, the hollow column and the rolling part will continue to rotate synchronously after a small distance of relative rotation. During the relative rotation of the hollow column and the rolling part, there will be a speed difference between the rolling part and the base, so that the ore particles can be ground while the rolling part squeezes the ore particles in the rolling trough downward, achieving a double crushing effect of the "crust" on the surface of the ore particles, and further ensuring the leaching rate of divalent iron ions inside the ore particles during the acid leaching process.

[0014] Preferably, the rolling part includes a rolling head and a push rod, the rolling head is arranged at the upper end of the push rod, the push rod is arranged vertically and its diameter is smaller than the diameter of the discharge hole; the rolling trough is arranged in a truncated cone shape, the bottom diameter of the rolling trough is smaller than the notch diameter of the rolling trough, and the diameter of the discharge hole is smaller than the bottom diameter of the rolling trough.

[0015] By adopting the above scheme, when the rolling head moves downward until it completely enters the rolling trough, the push rod can move downward synchronously with the rolling head, thereby pushing out the ore particles blocked in the discharge hole. In the process of the rolling head moving upward, the push rod can move upward with the rolling head. When the push rod is completely moved out from the inside of the discharge hole, the ore particles crushed by the rolling head can fall smoothly from the discharge hole, so that the ore particles transported to the top by the vortex can re-enter the inside of the rolling trough, thereby realizing repeated rolling treatment of the ore particles, and then the "crust" on the surface of the ore particles can be broken, achieving full contact between the ore particles and the acidic solution, thereby ensuring the leaching rate of divalent iron ions.

[0016] Preferably, the guide plate and the spoiler are arranged in the same direction, the guide plate is provided with a first flange, and the spoiler is provided with a second flange.

[0017] By adopting the above scheme, when the base drives the spoiler to rotate and causes the acidic solution inside the barrel to generate a vortex, the acidic solution in the vortex state can carry the ore particles and continue to flow along the installation direction of the spoiler. Under the action of flange one and flange two, the ore particles carried by the vortex can be further guided, so that the ore particles can move to the top of the base and then fall by their own gravity. The heavier ore particles will be thrown to a position close to the central axis of the barrel and fall into the inside of the rolling trough for re-rolling, thereby improving the crushing rate of the "crust" on the surface of the ore particles, effectively ensuring the dissolution effect of the acidic solution on the ore particles, and then ensuring the leaching rate of divalent iron ions.

[0018] Preferably, the support member includes an annular plate 2, an elastic telescopic rod and a bellows. The annular plate 2 is sleeved with the base, and here it is rotatably sleeved through a sealed bearing to ensure that the base can rotate inside the annular plate while also driving the annular plate to move downward during the pressure process. The two ends of the elastic telescopic rod and the bellows are respectively connected to the base and the barrel body, and the bellows is sleeved with the elastic telescopic rod.

[0019] By adopting the above scheme, in the process of the rolling head moving downward to enter the rolling trough, the elastic telescopic rod can be used to provide moving space for the annular plate 2, thereby ensuring that the rolling head can drive the base to move downward when squeezing the ore particles in the rolling trough, thereby avoiding obstruction of the rolling head during the downward movement, ensuring the reciprocating movement and continuous rotation of the rolling head in the vertical direction, and then being able to achieve continuous crushing of the "crust" on the surface of the ore particles, effectively ensuring the leaching rate of divalent iron ions.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Through the provided driving assembly and connecting assembly, the rolling head can be driven to move back and forth in the vertical direction while rotating during the operation of the motor, so that the rolling head can squeeze the ore particles gathered in the rolling trough after entering the interior of the rolling trough, and break the "crust" on the surface of the ore particles. At the same time, the ore particles stuck in the discharge hole after rolling are pushed out by the push rod at the bottom of the rolling head, so that the next downward movement of the rolling head can smoothly squeeze the ore particles in the rolling trough, thereby ensuring the leaching rate of divalent iron ions in the ore particles during the acid leaching process.

[0022] 2. Through the provision of spoilers and guide plates, when the U-shaped plate drives the base to rotate synchronously through the connecting assembly, the spoiler can be used to stir the acidic solution inside the barrel body, causing the acidic solution to produce a vortex. Under the action of the vortex, the ore particles are transported toward the guide plate at the inner edge of the barrel body, and the flow of the vortex in the guide plate drives the ore particles to move above the rolling seat. Finally, the ore particles will fall by their own gravity, and the ore particles falling inside the rolling trough can be re-rolled by the rolling head, thereby achieving repeated crushing of the "crust" on the surface of the ore particles, and further ensuring the leaching rate of divalent iron ions in the ore particles during the acid leaching process.

[0023] 3. By setting up the hollow column, fixed rod and torsion spring, when the torsion spring is deformed due to the friction of the ore particles during the rotation of the rolling head, the elastic force of the torsion spring and the friction of the ore particles can be used together to generate a speed difference between the rolling head and the base, thereby achieving the grinding of the ore particles, effectively ensuring the crushing rate of the "crust" on the surface of the ore particles, and further ensuring the leaching rate of divalent iron ions in the acid leaching process of the ore particles.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figures 1 to 9 The present invention provides a metal ion extraction device for ore samples used in mineral resource exploration, and the technical solution is as follows:

[0036] For details, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , a metal ion extraction device for ore samples used in mineral resource exploration, including a barrel body 1 and a barrel cover 2 arranged on the barrel body 1, and also including a motor 3, a drive assembly 4, a rolling piece 5, a rolling seat 6 support 7, a connecting assembly 8 and a guide plate 9, the motor 3 is arranged on the barrel cover 2, the drive assembly 4 includes a U-shaped plate 41, the U-shaped plate 41 is arranged at the output end of the motor 3, the rolling piece 5 and the rolling seat 6 are coaxially arranged inside the barrel body 1, and the rolling piece 5 is arranged above the rolling seat 6 and connected to the drive assembly 4, the drive assembly 4 also includes a reciprocating screw 42, a slider 43, a hinge 44, a bevel gear 45 and a bevel gear ring 46, the reciprocating screw 42 The U-shaped plate 41 is set through, the slider 43 is sleeved on the reciprocating screw 42, the hinge 44 is set inside the barrel body 1 and the two ends are hinged to the slider 43 and the rolling member 5 respectively, the bevel gear 45 is set at the end of the reciprocating screw 42, the bevel gear ring 46 is coaxially set inside the barrel body 1 and connected to the barrel cover 2, the bevel gear 45 is engaged with the bevel gear ring 46, the rolling seat 6 includes a base 61 and a spoiler 62, a rolling groove 611 is provided at the top of the base 61, and a discharge hole 612 is provided at the bottom of the rolling groove 611. When the rolling member 5 is squeezed with the ore particles in the rolling groove 611, the slider 43 forms a speed difference between the rolling member 5 and the base 61 through the hinge 44.

[0037] Under the above-mentioned setting conditions, when the motor 3 is working, the U-shaped plate 41 can rotate synchronously with the output end of the motor 3. When the U-shaped plate 41 rotates, it can drive the reciprocating screw 42 to rotate inside the barrel body 1 with the central axis of the barrel body 1 as the rotation axis. When the reciprocating screw 42 rotates, it can drive the bevel gear 45 at the end to rotate. Since the barrel cover 2 is provided with a bevel gear ring 46, and the bevel gear 45 is engaged with the bevel gear ring 46, the bevel gear 45 can rotate during the revolution, thereby driving the reciprocating screw 42 to rotate. During the rotation of the reciprocating screw 42, it can drive the slider 43 to move back and forth along the axis direction of the reciprocating screw 42. During the movement of 43, the hinge 44 can be driven to move. When the slider 43 moves to the end position of the reciprocating screw 42, the lower end of the hinge 44 is located at the uppermost position. When the slider 43 moves to the middle position of the reciprocating screw 42, the lower end of the hinge 44 is located at the lowermost position. At this time, if there are no ore particles inside the rolling groove 611, the rolling part 5 can fit with the inner wall of the rolling groove 611. If there are ore particles inside the rolling groove 611, the rolling part 5 will squeeze it, thereby breaking the "crust" on the surface of the ore particles, so that the ore particles can effectively contact the acidic solution, thereby ensuring the leaching rate of divalent iron ions in the ore particles.

[0038] As an embodiment of the present invention, refer to Figure 2 and Figure 6 The support member 7 is arranged inside the barrel body 1 and is connected to the rolling seat 6 and the barrel body 1. The support member 7 includes a second annular plate 71, an elastic telescopic rod 72 and a bellows 73. The second annular plate 71 is sleeved with the base 61, and the two ends of the elastic telescopic rod 72 and the bellows 73 are respectively connected to the base 61 and the barrel body 1, and the bellows 73 is sleeved with the elastic telescopic rod 72.

[0039] Under the above-mentioned setting conditions, when the rolling element 5 moves downward to enter the rolling groove 611, the elastic telescopic rod 72 can be used to provide moving space for the annular plate 2 71, thereby ensuring that the rolling element 5 can drive the base 61 to move downward when squeezing the ore particles in the rolling groove 611, thereby avoiding obstruction of the rolling element 5 during the downward movement, ensuring the reciprocating movement and continuous rotation of the rolling element 5 in the vertical direction, and then being able to achieve continuous crushing of the "crust" on the surface of the ore particles, effectively ensuring the leaching rate of divalent iron ions.

[0040] As an embodiment of the present invention, refer to Figure 2 、 Figure 4 and Figure 8The connecting component 8 is arranged inside the barrel body 1 and connects the U-shaped plate 41 and the rolling seat 6. When the U-shaped plate 41 rotates, the connecting component 8 drives the rolling part 5 to rotate and makes the acidic solution inside the barrel body 1 form a vortex. The connecting component 8 includes a circular ring 81, a U-shaped rod 82, a limiting rod 83, a limiting block 84 and an annular plate 85. The circular ring 81 is sleeved on the reciprocating screw 42, the U-shaped rod 82 is arranged on the annular plate 85, the limiting rod 83 is arranged on the base 61 and passes through the U-shaped rod 82, the slider 43 is sleeved on the limiting rod 83, and the annular plate 85 is sleeved on the base 61 and connected to the limiting block 84.

[0041] Under the above-mentioned setting conditions, when the reciprocating screw 42 rotates with the central axis of the barrel body 1 as the rotation axis, the ring 81 can follow the reciprocating screw 42 to perform orbital motion inside the barrel body 1, and the ring 81 can drive the U-shaped rod 82 to rotate when it revolves. Since the limiting rod 83 is arranged on the base 61 and passes through the U-shaped rod 82, the base 61 can be driven to rotate by the limiting rod 83 during the revolution of the U-shaped rod 82. Since a spoiler 62 is provided at the bottom of the base 61, the spoiler 62 can be used to make the acidic solution inside the barrel body 1 produce a swirling effect during the rotation of the base 61. The ore particles entrained in the swirling process can rub against each other, achieving an auxiliary crushing effect on the "crust" on the surface of the ore particles, thereby ensuring the contact range between the ore particles and the acidic solution, and then ensuring the leaching rate of divalent iron ions in the ore particles.

[0042] As an embodiment of the present invention, refer to Figure 3 、 Figure 5 and Figure 9 The hinged part 44 includes a hinged rod 441, a hollow column 442, a fixed rod 443 and a torsion spring 444. The upper end of the hinged rod 441 is hinged to the slider 43, the hollow column 442 is hinged to the lower end of the hinged rod 441, the fixed rod 443 is arranged on the rolling part 5 and is sleeved with the hollow column 442, the torsion spring 444 is sleeved on the fixed rod 443, and the two ends are respectively connected to the inner walls of the fixed rod 443 and the hollow column 442.

[0043] Under the above-mentioned setting conditions, when the rolling part 5 contacts the ore particles in the rolling groove 611 and the rotation of the rolling part 5 is hindered due to the friction force, the hinged rod 441 can drive the torsion spring 444 to deform. After the elastic force generated by the deformation of the torsion spring 444 is greater than or equal to the friction force exerted on the rolling part 5, the fixed rod 443 can drive the rolling part 5 to rotate normally under the drive of the torsion spring 444. During the deformation of the torsion spring 444, there is a speed difference between the rolling part 5 and the base 61, so that the rolling part 5 can grind the ore particles, thereby further breaking the "crust" on the surface of the ore particles, and further ensuring the leaching rate of divalent iron ions in the ore particles.

[0044] As an embodiment of the present invention, refer to Figure 6 The rolling part 5 includes a rolling head 51 and a push rod 52. The rolling head 51 is arranged at the upper end of the push rod 52. The push rod 52 is arranged vertically and its diameter is smaller than the diameter of the discharge hole 612. The rolling groove 611 is arranged in a truncated cone shape. The bottom diameter of the rolling groove 611 is smaller than the groove mouth diameter of the rolling groove 611. The diameter of the discharge hole 612 is smaller than the bottom diameter of the rolling groove 611.

[0045] Under the above-mentioned setting conditions, when the rolling head 51 moves down to the inside of the rolling trough 611, the push rod 52 set at the bottom of the rolling head 51 will enter the inside of the discharge hole 612. Under the action of stress, the push rod 52 can push out the ore particles blocked in the discharge hole 612. After entering the inside of the rolling trough 611, the ore particles can be partially retained by the shape design of the rolling trough 611, so that the rolling head 51 can squeeze the ore particles after entering the rolling trough 611, thereby realizing the circulation of the ore particles under the cyclone effect of the acidic solution, and then realizing multiple crushing of the crust on the surface of the ore particles, thereby ensuring the leaching rate of divalent iron ions.

[0046] As an embodiment of the present invention, refer to Figure 7 The guide plate 9 is arranged inside the barrel body 1 and there are multiple circular arrays. The swirling flow drives the ore particles to flow through the guide plate 9 to the top of the rolling seat 6 and fall into the inside of the rolling seat 6. The guide plate 9 and the spoiler 62 are arranged in the same direction. The guide plate 9 is provided with a flange 91, and the spoiler 62 is provided with a flange 2 621.

[0047] Under the above setting conditions, when the ore particles fall from the discharge hole 612 to the bottom of the base 61, since the base 61 is in a rotating state, the falling ore particles can be moved by the spoiler 62 and at the same time received by the flange 91, so that the spoiler 62 throws the ore particles to the edge position inside the barrel body 1 in the process of following the rotation of the base 61. Since the spoiler 62 and the guide plate 9 are arranged in the same direction, the vortex generated by the acidic solution during the rotation of the spoiler 62 can entrain the ore particles to the guide plate 9. Under the blocking action of flange 2 621 on plate 9, the ore particles can move upward on the guide plate 9 along the guide direction of the guide plate 9. After the ore particles are separated from the guide plate 9, they can fall due to their own weight. The ore particles that fall into the rolling groove 611 can be repeatedly rolled by the rolling head 51, and the ore particles that do not fall into the rolling groove 611 can rub against each other under the action of the cyclone, thereby achieving repeated crushing of the "crust" on the surface of the ore particles, effectively ensuring the leaching rate of divalent iron ions in the ore particles.

[0048] Working principle: In order to break the "crust" on the surface of ore particles during acid leaching, refer to Figure 2 and Figure 6By setting the driving assembly 4 and the connecting assembly 8, the rolling head 51 can be driven to rotate in the process of reciprocating movement in the vertical direction when the motor 3 is working, so as to break the "crust" on the surface of the ore particles inside the rolling tank 611, thereby ensuring the leaching rate of divalent iron ions; in order to avoid the "crust" on the surface of the ore particles being broken and then reappearing in the acid leaching process, refer to Figure 2 、 Figure 3 and Figure 7 By setting the spoiler 62 and the guide plate 9, the base 61 can be driven to rotate and form a vortex during the operation of the motor 3. Under the action of the vortex, the ore particles at the bottom are continuously guided and transported upward, thereby achieving repeated crushing of the ore particles and effectively further ensuring the leaching rate of divalent iron ions.

[0049] Specifically, the crushed ore particles are placed into the barrel body 1 and the barrel cover 2 is closed after adding the acid solution. The motor 3 is started, and the output end of the motor 3 drives the U-shaped plate 41 to rotate. During the rotation of the U-shaped plate 41, the reciprocating screw 42 is driven to rotate synchronously. Since bevel gears 45 are provided at both ends of the reciprocating screw 42, and a bevel gear ring 46 meshing with the two bevel gears 45 is provided under the barrel cover 2 and is fixed to the barrel cover 2, the reciprocating screw 42 can rotate under the meshing action of the bevel gears 45 and the bevel gear ring 46 as it rotates with the U-shaped plate 41.

[0050] In the process of the reciprocating screw 42 following the rotation of the U-shaped plate 41: on the one hand, since the circular ring 81 is set on the reciprocating screw 42, the circular ring 81 will follow the reciprocating screw 42 to perform orbital motion inside the barrel body 1 with the central axis of the barrel body 1 as the rotation axis. During the revolution of the circular ring 81, the U-shaped rod 82 can be driven to revolve. Since the limiting rod 83 passes through the U-shaped rod 82 and is connected to the base 61, and the base 61 is set inside the annular plate 71, the annular plate 71 is connected to the bottom of the barrel body 1 through the elastic telescopic rod 72, that is, the base 61 is restricted in the horizontal direction under the action of the annular plate 71 and the elastic telescopic rod 72. Under the limiting action of the annular plate 71 and the elastic telescopic rod 72, the U-shaped rod 82 can use the limiting rod 83 to drive the base 61 to rotate inside the annular plate 71 while revolving. During the rotation, the spoiler 62 at the bottom stirs the acidic solution inside the barrel body 1, causing the acidic solution inside the barrel body 1 to form a vortex and push the ore particles to the guide plate 9. Under the guidance of the guide plate 9, the ore particles follow the vortex and flow to the top of the base 61, and finally fall under the action of their own gravity. Since the spoiler 62 is arranged at the bottom of the base 61 and is located in the lower half of the barrel body 1, during the rotation of the base 61, the centrifugal force generated by the acidic solution in the lower half of the barrel body 1 is greater than that in the upper half. After being thrown onto the guide plate 9 by the centrifugal force generated by the vortex, the small particles of ore can move upward along the guide plate 9, and after flowing out from the top of the guide plate 9, they will scatter due to the reduction of centrifugal force, so that some ore particles can be thrown to a position close to the central axis of the barrel body 1 and finally fall into the inside of the rolling trough 611.

[0051] On the other hand, since a slider 43 is provided on the reciprocating screw rod 42, a hinged rod 441 is provided on the slider 43, a hollow column 442 is provided on the hinged rod 441, a fixed rod 443 is provided inside the hollow column 442, and the fixed rod 443 is provided on the rolling head 51, wherein the fixed rod 443 is connected to the hollow column 442 by a torsion spring 444, the rolling head 51 is driven to rotate by the slider 43, the hinged rod 441, the hollow column 442, the torsion spring 444 and the fixed rod 443 in the process of the revolution of the reciprocating screw rod 42. When the rolling head 51 contacts the ore particles inside the rolling trough 611, the rotation speed of the rolling head 51 is limited. At this time, the torsion spring 444 is deformed, so that a rotation speed difference occurs between the rolling head 51 and the base 61, thereby breaking the "crust" on the surface of the ore particles to ensure the leaching rate of divalent iron ions;

[0052] During the rotation of the reciprocating screw 42: Since the rolling head 51 is provided with an annular plate 85, and the annular plate 85 is connected to the limit rod 83 through the limit block 84, the rolling head 51 can only move in the vertical direction in addition to its rotation. Therefore, when the reciprocating screw 42 rotates, the slider 43 can reciprocate along the axis of the reciprocating screw 42, and the slider 43 can drive the rolling head 51 to reciprocate in the vertical direction through the hinge rod 441, the hollow column 442 and the fixed rod 443 during the movement, so that when the rolling head 51 enters the rolling groove 611, the grinding and extrusion of the ore particles can be achieved at the same time. Since the annular plate 2 71 and the bottom of the barrel body 1 are connected The two parts are connected by an elastic telescopic rod 72. The base 61 can move downward after being subjected to a downward extrusion force, thereby ensuring the normal operation of the rolling head 51. In the process of the rolling head 51 moving upward, the elastic force of the elastic telescopic rod 72 drives the annular plate 71 to drive the base 61 to reset, effectively ensuring the crushing effect of the "crust" on the surface of the ore particles; in the process of the rolling head 51 moving downward, the push rod 52 arranged at the bottom of the rolling head 51 can push out the ore particles blocked in the discharge hole 612, so that the ore particles move up again following the vortex during the rotation of the reciprocating screw 42, thereby realizing the continuous crushing of the "crust" on the surface of the ore particles, and further ensuring the leaching rate of divalent iron ions.
