Description

Technical Field

[0001] This utility model relates to the technical field of graded filtration devices, specifically a graded filtration device for internal slag material in cyanide tailings. Background Technology

[0002] Cyanide tailings are solid waste generated after the cyanide gold extraction process in the gold smelting industry. Its composition is complex, containing not fully recovered valuable metals such as gold and silver, as well as harmful components such as cyanide and heavy metals. Direct discharge can easily cause environmental pollution. At the same time, the tailings contain different particle sizes of slag materials (such as coarse tailings sand, fine muddy slag, and ultrafine dust) with different properties. They need to be graded to achieve efficient resource recovery and safe disposal. Therefore, a graded filtration device is required.

[0003] Existing grading and filtration devices are not suitable for multi-stage and precise grading of cyanide tailings during use. Most are single-stage or two-stage filters, which makes it difficult to separate the tailings into coarse, medium and fine particle sizes, resulting in insufficient targeting for subsequent resource recovery. Moreover, the vibration mechanism of most devices can only drive the vibration of a single screen plate, resulting in low grading efficiency and easy accumulation of slag that clogs the screen holes.

[0004] Based on this, a grading and filtration device for internal slag material of cyanide tailings is provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a grading and filtration device for internal slag material of cyanide tailings, so as to solve the problem in the prior art that it is not easy to achieve multi-level accurate grading of cyanide tailings.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cyanide tailings internal slag grading and filtration device includes a water tank, with a first support rod provided at each of the four corners of the water tank, a base provided between the tops of the four first support rods, and a filter box provided on the top of the base.

[0008] The filter box has two sets of sliding grooves on its inner wall. The filter plate is slidably installed inside the filter box through the sliding grooves. Two mounting plates are provided on one side of the filter box, and a vibration mechanism is provided on the top of the two mounting plates.

[0009] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0010] In one alternative embodiment: the vibration mechanism includes two reciprocating components, each reciprocating component including two mounting seats, the two mounting seats being fixedly mounted on the top of the mounting plate, and a drive shaft being rotatably mounted between the two mounting seats via a bearing. Both ends of the drive shaft are provided with cams, and a connecting rod is rotatably mounted on one side of each of the two cams. One end of each of the two connecting rods is rotatably mounted to the sieve plate.

[0011] In one alternative: a drive assembly is disposed on the outside of one of the drive shafts, and a linkage assembly is disposed between the two drive shafts.

[0012] In one alternative: the drive assembly includes a first gear keyed to the outside of one of the drive shafts, a second gear externally meshing with the first gear, a motor fixedly mounted on the top of one of the mounting plates, and the second gear being driven by the motor.

[0013] In one alternative embodiment: the linkage assembly includes two synchronous pulleys, which are respectively keyed to the outside of two drive shafts, and a synchronous belt is provided between the two synchronous pulleys.

[0014] In one alternative: a guide plate is provided on the other side of the filter box and at the feeding end of the sieve plate; a second collection box is placed on the top of the base and below the guide plate; a first collection box is placed on the top of the base and inside the filter box; a placement groove adapted to the first and second collection boxes is provided on the top of the base; and drainage holes are provided at the bottom of the placement groove, the first collection box, and the second collection box.

[0015] In one alternative: two second support rods are fixedly installed on the top of the base, and a third support rod is provided between the two mounting plates.

[0016] In one alternative: a water outlet pipe is provided on one side of the water tank.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model uses two sieve plates with different screen hole sizes, two corresponding guide plates and a second collection box to achieve three-stage separation of coarse slag, medium slag and fine slag of cyanide tailings. Different particle size slag materials are collected separately, which facilitates the subsequent targeted recovery of valuable metals or harmless disposal and improves resource utilization.

[0019] 2. The vibration mechanism of this utility model simultaneously drives two screen plates to vibrate. The upper screen plate pre-treats and separates coarse slag, while the lower screen plate further separates medium and fine slag. Compared with single screen plate grading, it is more efficient. The synchronous vibration ensures that the tailings are smoothly transferred between the two screen plates, avoiding accumulation and blockage. The layered design with the upper screen holes being larger than the lower screen holes, combined with the inertial force generated by vibration, allows the tailings to be fully dispersed and screened on each screen plate, reducing particle size mixing.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-4 As shown, a cyanide tailings internal slag grading and filtration device includes a water tank 1, with a first support rod 2 at each of the four corners of the water tank 1, a base 3 between the tops of the four first support rods 2, and a filter box 4 on the top of the base 3.

[0027] The filter box 4 has two sets of sliding grooves 5 on its inner wall. The filter plate 6 is slidably installed inside the filter box 4 through the sliding grooves 5. Two mounting plates 9 are provided on one side of the filter box 4, and a vibration mechanism 8 is provided on the top of the two mounting plates 9.

[0028] In this embodiment, two sieve plates 6 with different screen hole sizes, along with two corresponding guide plates 11 and a second collection box 13, achieve three-stage separation of cyanide tailings: coarse slag, medium slag, and fine slag. Different particle sizes of slag are collected separately, facilitating subsequent targeted recovery of valuable metals or harmless disposal and improving resource utilization. The vibration mechanism 8 simultaneously drives the two sieve plates 6 to vibrate. The upper sieve plate pre-treats and separates the coarse slag, while the lower sieve plate further separates the medium and fine slag. Compared with single-sieve plate grading, this is more efficient. The synchronous vibration ensures that the tailings are smoothly transferred between the two sieve plates, avoiding accumulation and blockage. The layered design with the upper sieve hole being larger than the lower sieve hole, combined with the inertial force generated by vibration, ensures that the tailings are fully dispersed and screened on each sieve plate, reducing particle size mixing.

[0029] In one embodiment, such as Figure 1 and Figure 3 As shown, the vibration mechanism 8 includes two reciprocating components, each including two mounting seats 81. The two mounting seats 81 are fixedly mounted on the top of the mounting plate 9. A drive shaft 82 is rotatably mounted between the two mounting seats 81 via a bearing. Cams 83 are provided at both ends of the drive shaft 82, and connecting rods 84 are rotatably mounted on one side of each of the two cams 83. One end of each connecting rod 84 is rotatably mounted to the sieve plate 6. A drive assembly is provided outside one of the drive shafts 82, and a linkage assembly is provided between the two drive shafts 82. The drive assembly includes a first gear 85, which is keyed to the outside of one of the drive shafts 82. A second gear 86 is meshed with the outside of the first gear 85. A motor 87 is fixedly mounted on the top of one of the mounting plates 9. The second gear 86 is driven by the motor 87. The linkage assembly includes two synchronous pulleys 88, which are keyed to the outside of the two drive shafts 82 respectively. A synchronous belt 89 is provided between the two synchronous pulleys 88. When the motor 87 of the vibration mechanism 8 is started, the motor 87 drives the second gear 86 to rotate. The second gear 86 meshes with the first gear 85 to rotate, thereby driving one of the drive shafts 82 to rotate. The two drive shafts 82 achieve linkage and synchronous rotation through the synchronous pulleys 88 and the synchronous belt 89. The cams 83 at both ends of the two drive shafts 82 rotate synchronously, respectively pushing the corresponding connecting rods 84 to reciprocate, thereby simultaneously driving the two screen plates 6 to reciprocate and vibrate along their respective slide grooves 5.

[0030] In one embodiment, such as Figure 1 and Figure 4As shown, a guide plate 11 is provided on the other side of the filter box 4 and at the discharge end of the sieve plate 6. A second collection box 13 is placed on the top of the base 3 and below the guide plate 11. A first collection box 12 is placed on the top of the base 3 and inside the filter box 4. A placement groove 14 adapted to the first collection box 12 and the second collection box 13 is opened on the top of the base 3. Drainage holes are opened at the bottom of the placement groove 14, the first collection box 12 and the second collection box 13. Under the vibration of the two sieve plates 6, the tailings with a particle size smaller than the sieve hole pass through the corresponding sieve hole and fall into the first collection box 12 in the filter box 4. The tailings with a particle size larger than the sieve hole slide along the sieve plate 6 to the guide plate 11 and are guided into the second collection box 13 through the guide plate 11. The wastewater in the first collection box 12 and the second collection box 13 flows into the water tank 1 through the drainage holes.

[0031] In one embodiment, such as Figure 1 and Figure 2 As shown, two second support rods 7 are fixedly installed on the top of the base 3, and a third support rod 10 is provided between the two mounting plates 9. A water outlet pipe 15 is provided on one side of the water tank 1, and the collected wastewater can be discharged or recycled through the water outlet pipe 15. The third support rod 10 and the second support rods 7 improve the stability of the two mounting plates 9, thereby improving the stability of the vibration mechanism 8.

[0032] The above embodiment discloses an internal slag grading and filtration device for cyanide tailings. In this device, the cyanide tailings are fed into the sieve plate 6 above the filter box 4. The motor 87 of the vibration mechanism 8 is started, and the motor 87 drives the second gear 86 to rotate. The second gear 86 meshes with the first gear 85 to rotate, thereby driving one of the drive shafts 82 to rotate. The two drive shafts 82 are linked and rotate synchronously through the synchronous pulley 88 and the synchronous belt 89. The cams 83 at both ends of the two drive shafts 82 rotate synchronously, respectively pushing the corresponding connecting rods 84 to reciprocate, thereby simultaneously driving the two sieve plates 6 to slide and vibrate back and forth along their respective slide grooves 5.

[0033] Under the vibration of the upper sieve plate 6 (with larger screen holes), coarse slag with a particle size larger than its screen holes slides down the plate surface to the corresponding guide plate 11, and is then guided into the corresponding second collection box 13; slag with a particle size smaller than the screen holes of the upper sieve plate 6 falls to the lower sieve plate 6 (with smaller screen holes), and under its vibration, medium slag with a particle size larger than the lower screen holes slides down the plate surface to another guide plate 11, and is then guided into another second collection box 13; fine slag with a particle size smaller than the screen holes of the lower sieve plate 6 passes through the screen holes and falls into the first collection box 12 in the filter box 4.

[0034] Wastewater from the first collection tank 12 and the two second collection tanks 13 flows into the base 3 through the drain hole, then collects in the water tank 1, and can finally be discharged or recycled through the outlet pipe 15, completing the three-stage filtration and collection of cyanide tailings.

[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
