Description

Technical Field

[0001] The invention relates to the technical field of tailings recovery, in particular to a non-ferrous metal tailings recovery machine. Background Art

[0002] Tailings recovery device is designed by absorbing foreign advanced technology and combining with the actual situation in my country. The use of tailings recovery device can effectively reduce the loss of tailings and control it below 3% (calculated by volume). It effectively reduces the content of effective components in tailings water, solves the pollution of tailings to the environment, and meets the emission standards required by environmental protection. It is widely used in metallurgy, mining, water conservancy, hydropower, sand and gravel plants, glass plants, coal preparation plants, coarse coal recovery and environmental protection projects, shield machines (mud purification) and other engineering projects.

[0003] In the process of tailings recovery, solvents are used to replace the metal elements in the tailings. However, after some tailings are accumulated, they will stick together due to factors such as moisture in the air. Some tailings are large in size, which wraps the metal elements inside and prevents them from reacting, resulting in low replacement efficiency. This leads to metal waste and the device doing a lot of useless work.

[0004] Therefore, a nonferrous metal tailings recovery machine is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a non-ferrous metal tailings recovery machine, which can break up and crush the tailings, expose the metal elements, make the replacement reaction more thorough, avoid the waste of metal elements, and improve the recovery efficiency, so as to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a non-ferrous metal tailings recovery machine, comprising a shell, a feed pipe is fixedly connected to the upper end of the shell near the left side, a liquid inlet pipe is fixedly connected to the left side of the shell near the lower end, a liquid outlet pipe is fixedly connected to the right side of the shell near the lower end, a discharge device is fixedly connected to the positions on both sides of the lower end of the shell, a motor is fixedly connected to the center of the upper end of the shell, a rotating rod is rotatably connected to the lower end of the motor, and stirring rods are movably connected to the positions of the rod wall near the lower end on both sides;

[0007] Crushing mechanisms are provided on both sides of the shell;

[0008] The crushing mechanism can crush the tailings entering the shell, so that the subsequent replacement reaction can be more ideal.

[0009] The metal tailings are transported into the interior of the shell through the feed pipe, and the solution required to react with the tailings is introduced into the interior of the shell through the liquid inlet pipe. At this time, the motor starts to work, the motor drives the rotating rod to rotate, and the rotating rod drives the stirring rod to rotate, so that the solution and the tailings undergo a replacement reaction, and the replaced solution discharges the reacted solution through the liquid outlet pipe, and then the tailings are discharged through the discharging device. The tailings entering the shell can be crushed by the crushing mechanism, and the uncrushed ones are repeatedly crushed, which improves the crushing effect and makes the efficiency of the replacement reaction better.

[0010] Preferably, the crushing mechanism includes a pressure roller, which is movably connected to the right side of the rod wall of the rotating rod, a filter plate is fixedly connected to the upper end of the inner wall of the shell near the upper end, the upper end of the filter plate is fitted with the rod wall of the pressure roller, a filter screen is fixedly connected to the inner wall of the shell near the lower end, discharge ports are opened at the center of both sides of the shell, feed ports are opened at both sides of the shell near the upper end, an outer cover is fixedly connected to both sides of the shell, a push rod is rotatably connected to the inner wall of the outer cover, the upper ends of the rod walls of the two push rods are rotatably connected to a belt together, the center of the belt is rotatably connected to the position of the rotating rod near the upper end, and a toggle rod is fixedly connected to the rod wall of the rotating rod.

[0011] When the rotating rod rotates, it drives the pressure roller to rotate. When the pressure roller rotates, the tailings entering the shell are crushed. The crushed tailings pass through the filter plate with larger filter holes and fall to the upper end of the filter. At this time, the filter will screen some completely crushed tailings and fall into the lower end of the shell. The toggle rod rotates with the rotating rod to push the tailings on the edge of the filter to both sides of the discharge port. The rotation of the rotating rod drives the belt to rotate, and the rotation of the belt drives the two pushing rods to rotate. The rotation of the pushing rod will push the screened tailings upward. The tailings pushed upward fall through the feed port to the upper end of the filter plate and are crushed by the pressure roller again, so that the tailings are crushed in the middle.

[0012] Preferably, the filter screen is designed to be inverted cone shape.

[0013] Because the filter is inverted cone shape, the tailings that are not passed through the filter move to both sides of the filter.

[0014] Preferably, a slide groove is provided on the right side of the rotating rod, a slider is slidably connected inside the slide groove, a first spring is fixedly connected to the lower end of the slider, and the right side of the slider is rotatably connected to the left side of the pressure roller.

[0015] When the pressure roller encounters relatively solid stones when pressing the tailings, the magnetic pressure roller drives the slider to move upward inside the chute and stretches the first spring at the same time, thus preventing the pressure roller from getting stuck.

[0016] Preferably, the inner wall of the shell is fixedly connected to support rods at both sides below the filter, a fixed shell is commonly fixedly connected between the two support rods, the center of the fixed shell is rotatably connected to the rod wall of the rotating rod, knocking plates are inserted on both sides of the upper end of the fixed shell, the lower end of the second spring is fixedly connected to the inner wall of the lower end of the fixed shell, the two knocking plates are fixedly connected to fixed blocks at positions near the lower ends on the opposite sides, the lower ends of the fixed blocks are fixedly connected to the second spring, the opposite sides of the two knocking plates are fixedly connected to the first clamping blocks, and the rod walls of the rotating rod are fixedly connected to the second clamping blocks at both sides inside the fixed shell.

[0017] When the rotating rod rotates, it drives the two second blocks to rotate. The rotation of the second blocks causes the first block to move downward. The first block drives the knocking plate to move downward. The knocking plate drives the fixed block to move downward and compresses the second spring. When the second block is misaligned with the first block, the second spring resets and pushes the knocking plate to move upward quickly, thereby knocking the filter screen. This can make the screening efficiency of the filter screen faster. At the same time, vibration can speed up the movement of tailings that have not passed through the filter screen to both sides of the filter screen.

[0018] Preferably, the upper end of the knocking plate fits with the lower end of the filter.

[0019] The force-bearing area is increased, making the vibration effect better.

[0020] Preferably, the right side of the liquid inlet pipe is fixedly connected to a box body, the center of the box body is rotatably connected to the rod wall of the rotating rod, the rod wall of the rotating rod is located at the position of the box body and has through holes on both sides, the interior of the stirring rod is provided with a first cavity, and the rod wall of the stirring rod is evenly provided with leakage holes.

[0021] The solution enters the interior of the box through the liquid inlet pipe, flows into the interior of the first cavity through the through hole, and is discharged through the liquid leakage hole, so that the liquid can be introduced when the stirring rod is stirring.

[0022] Preferably, the back-to-back sides of the two stirring rods are fixedly connected with a cross bar, the back-to-back sides of the two cross bars are fixedly connected with a gear, a second cavity is opened inside the shell near the lower end, the lower end of the second cavity is fixedly connected with a rack, the upper end of the rack is meshingly connected with the outer side of the gear, the opposite sides of the two stirring rods are rotatably connected with the two sides of the rotating rod, and the rod walls of the stirring rods are evenly and fixedly connected with rod members.

[0023] When the stirring rod rotates, it drives the cross bar to rotate, and the movement of the cross bar drives the gear to move. Because the gear and the rack are meshing, the gear will rotate when it moves on the rack. The rotation of the gear causes the cross bar to rotate, and the rotation of the cross bar drives the stirring rod to rotate. The rotation of the stirring rod drives the rod to move, so that horizontal stirring can be achieved while vertical stirring is performed, thereby improving the stirring efficiency.

[0024] Preferably, both upper and lower ends of the second cavity near the inner wall of the shell are rotatably connected to waterproof bearings, and a sealing plate is fixedly connected between the two waterproof bearings.

[0025] When the cross bar rotates, the sealing plate is driven to rotate, because the upper and lower ends of the sealing plate are fixedly connected with waterproof bearings, thus preventing tailings and solution from entering the second cavity, thereby improving the practicability of the device.

[0026] Preferably, the rack and the second cavity are both circular in design.

[0027] This ensures that the rack and gear are always in meshing state.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The tailings can be broken up and crushed to expose the metal elements, making the replacement reaction more thorough, avoiding the waste of metal elements and improving the recovery efficiency;

[0030] 2. Beat the filter, which can make the screening efficiency of the filter faster. At the same time, vibration can speed up the movement of tailings that have not passed through the filter to both sides of the filter, thereby improving the practicality of the device.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0040] See also Figures 1 to 6 , the present invention provides a technical solution:

[0041] A non-ferrous metal tailings recovery machine, such as Figure 1 to Figure 2 As shown, it comprises a shell 1, a feed pipe 30 is fixedly connected to the upper end of the shell 1 near the left side, a liquid inlet pipe 6 is fixedly connected to the left side of the shell 1 near the lower end, a liquid outlet pipe 7 is fixedly connected to the right side of the shell 1 near the lower end, and discharge devices 16 are fixedly connected to the positions on both sides of the lower end of the shell 1, a motor 2 is fixedly connected to the center of the upper end of the shell 1, a rotating rod 3 is rotatably connected to the lower end of the motor 2, and stirring rods 4 are movably connected to the rod walls of the rotating rod 3 near both sides of the lower end;

[0042] Crushing mechanisms 8 are provided on both sides of the housing 1;

[0043] The crushing mechanism 8 can crush the tailings entering the shell 1, so that the subsequent replacement reaction can be more ideal;

[0044] During operation, the metal tailings are transported into the interior of the shell 1 through the feed pipe 30, and the solution required to react with the tailings enters the interior of the shell 1 through the liquid inlet pipe 6. At this time, the motor 2 starts to work, and the motor 2 drives the rotating rod 3 to rotate, and the rotating rod 3 drives the stirring rod 4 to rotate, so that the solution and the tailings undergo a replacement reaction, and the replaced solution discharges the reacted solution through the liquid outlet pipe 7, and then the tailings are discharged through the discharging device 16. The tailings entering the shell 1 can be crushed by the crushing mechanism 8, and the uncrushed ones are repeatedly crushed, thereby improving the crushing effect and making the efficiency of the replacement reaction better.

[0045] As an embodiment of the present invention, Figure 1 and Figure 2 As shown, the crushing mechanism 8 includes a pressure roller 801, which is movably connected to the right side of the rod wall of the rotating rod 3, a filter plate 808 is fixedly connected to the inner wall of the shell 1 near the upper end, and the upper end of the filter plate 808 is in contact with the rod wall of the pressure roller 801, and a filter screen 802 is fixedly connected to the inner wall of the shell 1 near the lower end, and discharge ports 803 are opened at the center of both sides of the shell 1, and feed ports 804 are opened at both sides of the shell 1 near the upper end, and outer covers 806 are fixedly connected to both sides of the shell 1, and the inner wall of the outer cover 806 is rotatably connected to a push rod 805, and the upper ends of the rod walls of the two push rods 805 are rotatably connected to a belt 807 together, and the center of the belt 807 is rotatably connected to the position near the upper end of the rotating rod 3, and the rod wall of the rotating rod 3 is fixedly connected to a toggle rod 809, and the filter screen 802 is designed as an inverted cone;

[0046] During operation, when the rotating rod 3 rotates, it drives the pressing roller 801 to rotate. When the pressing roller 801 rotates, the tailings entering the housing 1 are crushed. The crushed tailings pass through the filter plate 808 with larger filter holes and fall to the upper end of the filter screen 802. At this time, the filter screen 802 will screen some completely crushed tailings and fall into the lower end of the housing 1. Because the filter screen 802 is inverted cone shape, the tailings that are not passed by the filter screen 802 move to the two sides of the filter screen 802. The toggle rod 809 rotates with the rotating rod 3 to move the tailings on the sides of the filter screen 802. The tailings on the edge are pushed to both sides of the discharge port 803, the rotating rod 3 rotates to drive the belt 807 to rotate, the belt 807 rotates to drive the two pushing rods 805 to rotate, the pushing rods 805 rotate to push the screened tailings upward, and the tailings pushed upward fall to the upper end of the filter plate 808 through the feed port 804, and are crushed again by the pressure roller 801, so that the tailings are crushed in the middle; in this way, the tailings can be broken up and crushed, the metal elements are exposed, the replacement reaction is more thorough, the waste of metal elements is avoided, and the recovery efficiency is improved.

[0047] As an embodiment of the present invention, Figure 4As shown, a slide groove 20 is provided on the right side of the rotating rod 3, a slider 18 is slidably connected inside the slide groove 20, a first spring 19 is fixedly connected to the lower end of the slider 18, and the right side of the slider 18 is rotatably connected to the left side of the pressure roller 801;

[0048] During operation, when the pressure roller 801 encounters relatively solid stones when pressing the tailings, the magnetic pressure roller 801 drives the slider 18 to move upward inside the slide 20 and stretches the first spring 19 at the same time. This can avoid the pressure roller 801 from being stuck and protect the pressure roller 801 from being damaged, thereby improving the practicality of the device.

[0049] As an embodiment of the present invention, Figure 3 and Figure 6 As shown, the inner wall of the shell 1 is fixedly connected to the support rods 5 on both sides below the filter 802, and a fixed shell 9 is fixedly connected between the two support rods 5. The center of the fixed shell 9 is rotatably connected to the rod wall of the rotating rod 3, and knocking plates 10 are inserted on both sides of the upper end of the fixed shell 9. The two knocking plates 10 are fixedly connected to the positions near the lower ends on the opposite sides, and the lower ends of the fixed blocks 11 are fixedly connected to the second spring 12. The lower ends of the second springs 12 are fixedly connected to the inner wall of the lower end of the fixed shell 9, and the opposite sides of the two knocking plates 10 are fixedly connected to the first clamping blocks 13, and the rod walls of the rotating rod 3 are fixedly connected to the positions on both sides inside the fixed shell 9. The upper ends of the knocking plates 10 fit the lower end of the filter 802.

[0050] During operation, when the rotating rod 3 rotates, it drives the two second blocks 14 to rotate, and the rotation of the second blocks 14 causes the first block 13 to move downward. It is explained here that the second block 14 is arc-shaped, and the second block 14 and the first block 13 are in a staggered distribution. The first block 13 drives the knocking plate 10 to move downward, and the knocking plate 10 drives the fixed block 11 to move downward and compress the second spring 12. When the second block 14 is misaligned with the first block 13, the second spring 12 is reset and pushes the knocking plate 10 to move upward quickly, thereby knocking the filter 802, which can make the screening efficiency of the filter 802 faster. At the same time, the vibration can accelerate the movement of the tailings that have not passed through the filter 802 to the two sides of the filter 802, thereby improving the practicability of the device.

[0051] As an embodiment of the present invention, Figure 3 and Figure 5As shown, the right side of the liquid inlet pipe 6 is fixedly connected with a box body 15, the center of the box body 15 is rotatably connected with the rod wall of the rotating rod 3, the rod wall of the rotating rod 3 is located at the box body 15 and has through holes 17 on both sides, the inside of the stirring rod 4 is provided with a first cavity 27, and the rod wall of the stirring rod 4 is evenly provided with leakage holes 26;

[0052] During operation, the solution enters the interior of the housing 15 through the liquid inlet pipe 6, flows into the interior of the first cavity 27 through the through hole 17, and is discharged through the leakage hole 26. In this way, liquid can be introduced when the stirring rod 4 is stirring, making the reaction effect more ideal.

[0053] As an embodiment of the present invention, Figure 5 As shown, the back-to-back sides of the two stirring rods 4 are fixedly connected with a cross bar 25, and the back-to-back sides of the two cross bars 25 are fixedly connected with a gear 21. A second cavity 29 is opened near the lower end of the inner part of the shell 1, and a rack 23 is fixedly connected to the lower end of the second cavity 29. The upper end of the rack 23 is meshed with the outer side of the gear 21. The opposite sides of the two stirring rods 4 are correspondingly rotatably connected to the two sides of the rotating rod 3. The rod wall of the stirring rod 4 is evenly fixedly connected with a rod member 28. The upper and lower ends of the second cavity 29 near the inner wall of the shell 1 are rotatably connected to the waterproof bearing 22, and a sealing plate 24 is fixedly connected between the two waterproof bearings 22.

[0054] During operation, when the stirring rod 4 rotates, the cross bar 25 is driven to rotate, and the movement of the cross bar 25 drives the gear 21 to move. Because the gear 21 is meshed with the rack 23, the gear 21 will rotate when it moves on the rack 23. The rotation of the gear 21 causes the cross bar 25 to rotate, and the rotation of the cross bar 25 drives the stirring rod 4 to rotate. The rotation of the stirring rod 4 drives the rod 28 to move, so that horizontal stirring and vertical stirring can be performed at the same time, thereby improving the stirring efficiency. When the cross bar 25 rotates, it drives the sealing plate 24 to rotate, because the upper and lower ends of the sealing plate 24 are fixedly connected to the waterproof bearings 22, so that tailings and solution can be prevented from entering the second cavity 29, thereby improving the practicability of the device.

[0055] Working principle:

[0056] During operation, the metal tailings are transported into the interior of the shell 1 through the feed pipe 30, and the solution required to react with the tailings is transported into the interior of the shell 1 through the liquid inlet pipe 6. At this time, the motor 2 starts to work, and the motor 2 drives the rotating rod 3 to rotate, and the rotating rod 3 drives the stirring rod 4 to rotate, so that the solution and the tailings undergo a replacement reaction, and the replaced solution discharges the reacted solution through the liquid outlet pipe 7, and then the tailings are discharged through the discharging device 16. The tailings entering the shell 1 can be crushed by the crushing mechanism 8, and the uncrushed ones are repeatedly crushed, thereby improving the crushing effect and making the replacement reaction more efficient. When the rotating rod 3 rotates, it drives the pressing roller 801 to rotate, and when the pressing roller 801 rotates, the tailings entering the shell 1 are crushed. The tailings pass through the filter plate 808 with larger filter holes and fall to the upper end of the filter screen 802. At this time, the filter screen 802 will screen some of the completely crushed tailings and fall into the lower end of the shell 1. Because the filter screen 802 is inverted cone shape, the tailings that have not passed through the filter screen 802 move to the two sides of the filter screen 802. The toggle rod 809 rotates with the rotating rod 3 to push the tailings on the edge of the filter screen 802 to the two sides of the discharge port 803. The rotation of the rotating rod 3 drives the belt 807 to rotate. The rotation of the belt 807 drives the two push rods 805 to rotate. The push rod 805 rotates to push the screened tailings upward. The tailings pushed upward pass through the feed port 804 and fall to the upper end of the filter plate 808. They are crushed by the pressure roller 801 again, so that the tailings are crushed in the middle.In this way, the tailings can be broken up and crushed, the metal elements are exposed, the replacement reaction is more thorough, the waste of metal elements is avoided, and the recovery efficiency is improved. When the pressure roller 801 encounters a relatively solid stone when pressing the tailings, the magnetic pressure roller 801 drives the slider 18 to move upward inside the slide 20, and at the same time stretches the first spring 19, so that the pressure roller 801 can be prevented from being stuck, and the practicality of the device is improved. When the rotating rod 3 rotates, it drives the two second blocks 14 to rotate, and the rotation of the second block 14 causes the first block 13 to move downward, and the first block 13 drives the knocking plate 10 to move downward, and the knocking plate 10 drives the fixed block 11 to move downward to compress the second spring 12. When the second block 14 is misaligned with the first block 13, the second spring 12 is reset at this time to push the knocking plate 10 to move upward quickly, so that the filter screen 802 is knocked, which can make the screening efficiency of the filter screen 802 faster, and at the same time, the vibration can speed up the tailings that have not passed through the filter screen 802 to the filter screen The two sides of 802 move, which improves the practicality of the device. The solution enters the interior of the box body 15 through the liquid inlet pipe 6, and the solution flows into the interior of the first cavity 27 through the through hole 17, and is discharged through the leakage hole 26. In this way, when the stirring rod 4 stirs, the liquid can be introduced, so that the reaction effect is more ideal. When the stirring rod 4 rotates, the cross bar 25 is driven to rotate, and the movement of the cross bar 25 drives the gear 21 to move. Because the gear 21 is meshed with the rack 23, the gear 21 will rotate when it moves on the rack 23. The rotation of the gear 21 causes the cross bar 25 to rotate, and the rotation of the cross bar 25 drives the stirring rod 4 to rotate. The rotation of the stirring rod 4 drives the rod 28 to move, so that the horizontal stirring can be carried out at the same time. Vertical stirring improves the stirring efficiency. When the cross bar 25 rotates, it drives the sealing plate 24 to rotate, because the upper and lower ends of the sealing plate 24 are fixedly connected to the waterproof bearing 22, so that the tailings and the solution can be prevented from entering the interior of the second cavity 29, which improves the practicality of the device. ;

The upper end of the rack (23) is meshedly connected to the outer side of the gear (21). The opposite sides of the two stirring rods (4) are correspondingly connected to the two sides of the rotating rod (3) for rotation, and the rod walls of the stirring rods (4) are evenly fixedly connected to rod members (28); The rack (23) and the second cavity (29) are both circular in design; When the rotating rod (3) rotates, it drives the two second clamping blocks (14) to rotate, and the rotation of the second clamping blocks (14) causes the first clamping block (13) to move downward. It is explained here that the second clamping block (14) is in an arc shape, and the second clamping block (14) and the first clamping block (13) are in a dislocated distribution. The first clamping block (13) drives the knocking plate (10) to move downward, and the knocking plate (10) drives the fixed block (11) to move downward to compress the second spring (12). When the second clamping block (14) and the first clamping block (13) are dislocated, the second spring (12) is reset to push the knocking plate (10) to move upward quickly, so that the filter screen (802) is knocked, and at the same time, the vibration can accelerate the tailings that have not passed through the filter screen (802) to move to both sides of the filter screen (802); When the stirring rod (4) rotates, the cross bar (25) is driven to rotate, and the movement of the cross bar (25) drives the gear (21) to move. Because the gear (21) is meshed with the rack (23), the gear (21) rotates when it moves on the rack (23). The rotation of the gear (21) causes the cross bar (25) to rotate. The rotation of the cross bar (25) drives the stirring rod (4) to rotate. The rotation of the stirring rod (4) drives the rod (28) to move. In this way, the stirring can be performed horizontally and vertically at the same time.
