DETAILED DESCRIPTION
[0037] Figures 1 to 9 The best embodiment of the present invention is shown below in conjunction with the attached Figures 1 to 9 The present invention is further described.
[0038] A leaching device comprises an inner cylinder 1 and an outer cylinder 2 which are arranged vertically, and a main shaft 13 which is arranged in the inner cylinder 1. The bottom end of the outer cylinder 2 is closed by a bottom plate 3. The inner cylinder 1 is a cylinder which is open at both the upper and lower ends. The inner cylinder 1 is arranged in the outer cylinder 2. The bottom plate 3 is coaxially connected with the main shaft 13 and keeps synchronous rotation. A plurality of partitions 16 are arranged between the main shaft 13 and the inner cylinder 1 and divide the inner cavity of the inner cylinder 1 into a plurality of leaching chambers 17 which are arranged around the main shaft 13. The partitions 16 are connected with the main shaft 13 and rotate synchronously with the main shaft 13. An outer cylinder 2 is arranged outside the inner cylinder 1 of the leaching device. When the extractant enters the leaching chamber 17, the extractant will enter the gap between the inner cylinder 1 and the outer cylinder 2 without causing leakage. The outer cylinder 2 and the chassis 3 rotate synchronously, which is convenient for sealing the outer cylinder 2 and the chassis 3. Moreover, the gap between the inner cylinder 1 and the chassis 3 is also very small. The speed at which the extractant enters the gap between the inner cylinder 1 and the outer cylinder 2 from the inner cylinder 1 is very slow, which fundamentally solves the leakage problem. The sealing is reliable and does not require frequent maintenance. The height or diameter of the inner cylinder 1 and the outer cylinder 2 can be increased as needed, which also improves the leaching efficiency.
[0039] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still belong to the scope of protection of the present application.
[0040] Example 1
[0041] like Figures 1 to 3 As shown: the inner cylinder 1 is a cylinder with both ends open, the inner cylinder 1 is arranged vertically, and the lower end of the inner cylinder 1 is connected to the chassis 3. The outer cylinder 2 is arranged coaxially with the inner cylinder 1, and the inner diameter of the outer cylinder 2 is larger than the outer diameter of the inner cylinder 1. In this embodiment, the height of the inner cylinder 1 is equal to the height of the outer cylinder 2. The height of the inner cylinder 1 can also be greater than or less than the height of the outer cylinder 2. The bottom of the outer cylinder 2 is integrally provided with a chassis 3, which is a disk with a diameter equal to the outer diameter of the outer cylinder 2. The chassis 3 closes the bottom end of the outer cylinder 2, and the chassis 3 is integrally provided with the outer cylinder 2. The bottom end of the inner cylinder 1 is rotatably connected to the top surface of the chassis 3. The main shaft 13 is coaxially arranged in the inner cylinder 1, and the lower end of the main shaft 13 is connected to the chassis 3 and drives the turntable. Since the inner cylinder 1 is rotatably connected to the bottom plate 3, the speed at which the extractant in the inner cylinder 1 passes through the gap between the inner cylinder 1 and the bottom plate 3 and enters the gap between the inner cylinder 1 and the outer cylinder 2 is very slow. Moreover, since the heights of the inner cylinder 1 and the outer cylinder 2 are equal and the extractant in the inner cylinder 1 is not filled, the extractant in the gap between the inner cylinder 1 and the outer cylinder 2 will not overflow from the outer cylinder 2, thereby solving the sealing problem between the inner cylinder 1 and the bottom plate 3.
[0042] A plurality of partitions 16 are arranged in the inner cylinder 1, and the partitions 16 are arranged along the radial direction of the inner cylinder 1. The inner side of the partition 16 is fixedly connected to the side of the main shaft 13 and rotates synchronously with the main shaft 13. The outer side of the partition 16 is fixedly connected to the inner wall of the inner cylinder 1, so that the inner cylinder 1 rotates synchronously with the main shaft 13. The bottom of the partition 16 is also fixedly connected to the bottom plate 3 and the bottom plate 3 also rotates synchronously with the partition 16, thereby dividing the inner cavity of the inner cylinder 1 into a plurality of independent leaching chambers 17.

A plurality of through holes are arranged on the wall of the liquid outlet pipe 9 at intervals, so that the mixed liquid can be uniformly delivered to the material in the leaching bin 17, which can not only achieve a stirring effect, but also ensure that the material and the mixed liquid are fully mixed. The delivery pipe 10 is mainly used to pump out the material and the mixed liquid in the leaching bin 17, and is also used to add fresh materials and extractants into the leaching bin 17.
[0045] The upper end of the overflow pipe 4 is vertically arranged in the leaching bin 17, and the upper end of the overflow pipe 4 is arranged in the middle of the leaching bin 17.

[0046] A counterflow valve 18 is provided on the counterflow pipe 19, and a reflux valve 8 is provided on the reflux pipe 7. The counterflow valve 18 and the reflux valve 8 can control the amount of mixed liquid reflux and reverse flow. Usually, the leaching process is mainly self-circulation and supplemented by reverse flow, that is, the flow rate of the reflux pipe 7 is greater than the flow rate of the counterflow pipe 19.
[0047] A liquid collecting hopper is provided at the lower side of each leaching tank 17. The liquid collecting hopper is a cone with a gradually decreasing cross-sectional area from top to bottom. The upper end of the liquid collecting hopper is connected to the lower end of the overflow pipe 4 of the corresponding leaching tank 17 on the upper side, and the top of the liquid collecting hopper is connected to the liquid inlet end of the corresponding circulation pump 5.
[0048] like Figures 4 to 6 As shown: a rotating disk 11 and a fixed disk 12 are coaxially arranged on the main shaft 13 on the upper side of the inner cylinder 1, and the rotating disk 11 is arranged on the lower side of the fixed disk 12. The diameter of the rotating disk 11 and the diameter of the fixed disk 12 are both smaller than the inner diameter of the inner cylinder 1. The rotating disk 11 is fixedly connected to the partition 16 and rotates synchronously with the partition 16. The fixed disk 12 is installed on the ground through a bracket.
[0049] A turntable shaft hole 1101 is provided in the middle of the turntable 11, and the turntable 11 is fixedly connected to the main shaft 13 through the turntable shaft hole 1101 and rotates synchronously with the main shaft 13. A plurality of delivery holes 1103 are evenly spaced on the side of the turntable 11, and the center lines of the delivery holes 1103 are arranged parallel to the axis of the turntable 11, and the delivery holes 1103 correspond to the leaching bins 17 one by one.

The upper end of the delivery pipe 10 in each leaching bin 17 is connected to the delivery hole 1103.
[0050] The fixed disk 12 is a disk having a diameter equal to that of the rotating disk 11. A fixed disk shaft hole 1201 is provided in the middle of the fixed disk 12. The fixed disk 12 is rotatably connected to the main shaft 13 through the fixed disk shaft hole 1201. The fixed disk 12 is sealed to the rotating disk 11, thereby closing the upper side of the conveying groove 1102 to form a plurality of conveying cavities.
[0051] The side of the fixed disk 12 is provided with a liquid inlet hole 1202, an output hole 1203 and a feed hole 1204 in sequence along the rotation direction of the main shaft 13, and the center lines of the liquid inlet hole 1202, the output hole 1203 and the feed hole 1204 are all arranged parallel to the center line of the main shaft 13. The spacing between the liquid inlet hole 1202 and the output hole 1203 and the output hole 1203 and the feed hole 1204 is equal to the spacing between the adjacent conveying holes 1103, and the distance between the center line of the liquid inlet hole 1202, the output hole 1203 and the feed hole 1204 and the center line of the main shaft 13 is equal to the distance between the center line of the conveying hole 1103 and the center line of the main shaft 13. The liquid inlet hole 1202, the output hole 1203 and the feed hole 1204 are all through holes. The upper side of the liquid inlet hole 1202 is connected to a liquid inlet pipe 14, on which a liquid inlet valve is arranged; the output hole 1203 is connected to an output pump; the upper side of the feed hole 1204 is provided with a feed pipe, on which a feed valve is arranged.
[0052] Since the fixed disk 12 is fixedly arranged, when the leaching bin 17 rotates to the lower side of the liquid inlet hole 1202, the conveying hole 1103 corresponding to the leaching bin 17 is connected with the liquid inlet hole 1202, thereby replenishing the leaching bin 17 with fresh extractant; when the leaching bin 17 rotates to the lower side of the output hole 1203 of the fixed disk 12, the conveying hole 1103 in the leaching bin 17 is aligned with and connected with the output hole 1203, and the output pump pumps out the material and the mixed liquid; when the leaching bin 17 rotates to the lower side of the feed hole 1204 of the fixed disk 12, the conveying hole 1103 corresponding to the leaching bin 17 is connected with the feed hole 1204, thereby replenishing the leaching bin 17 with fresh material, thereby realizing continuous leaching, and the material can be replenished and output without stopping.
[0053] like Figure 7-8 As shown, the lower side of the chassis 3 is provided with a liquid separation moving plate 20 and a liquid separation fixed plate 21 in sequence from top to bottom.
[0054] A movable disc shaft hole 2001 is coaxially arranged in the middle of the liquid separation movable disc 20. The liquid separation movable disc 20 is sleeved outside the main shaft 13 through the movable disc shaft hole 2001 and rotates synchronously with the main shaft 13. An overflow hole 2002 parallel to the axis of the liquid separation movable disc 20 is arranged on the liquid separation movable disc 20. The overflow hole 2002 corresponds to the leaching bin 17 one by one, and a plurality of overflow holes 2002 are evenly distributed around the liquid separation movable disc 20. A movable disc liquid outlet groove 2003 is arranged on the lower side of the liquid separation movable disc 20. The movable disc liquid outlet groove 2003 is in an arc shape coaxial with the liquid separation movable disc 20. The central angle corresponding to the movable disc liquid outlet groove is smaller than the central angle corresponding to the leaching bin 17. The movable disc liquid outlet groove 2003 corresponds to the overflow hole 2002 one by one, and the movable disc liquid outlet groove 2003 is connected with the corresponding overflow hole 2002. The side of the liquid-separating movable disk 20 is provided with radial movable disk liquid outlet holes 2004, which correspond one-to-one to the overflow holes 2002. The inner ends of the movable disk liquid outlet holes 2004 are connected to the sides of the corresponding overflow holes 2002, and the outer ends of the movable disk liquid outlet holes 2004 are provided on the side of the liquid-separating movable disk 20.
[0055] like Fig. 9 As shown in the figure: the diameter of the liquid separation fixed plate 21 is equal to the diameter of the liquid separation moving plate 20, and a fixed plate shaft hole 2101 is coaxially arranged in the middle of the liquid separation fixed plate 21. The liquid separation fixed plate 21 is sleeved outside the main shaft 13 through the fixed plate shaft hole 2101 and is rotatably connected with the main shaft 13. The side of the liquid separation fixed plate 21 is provided with a fixed plate liquid outlet hole 2102 parallel to the axis, and the distance from the fixed plate liquid outlet hole 2102 to the axis of the main shaft 13 is equal to the distance from the center line of the moving plate liquid outlet groove 2003 to the axis of the main shaft 13, and the axis of the fixed plate liquid outlet hole 2102 is located in the plane determined by the axis of the feed hole 1204 and the axis of the main shaft 13.
[0056] Each overflow hole 2002 is connected to the liquid outlet of the corresponding liquid collecting hopper on the lower side, and the liquid outlet hole 2004 of the moving plate is connected to the liquid inlet end of the corresponding circulation pump 5. The lower side of the liquid separation moving plate 20 is sealed and connected to the upper side of the liquid separation fixed plate 21. During the rotation of the liquid separation moving plate 20, each liquid outlet groove 2003 of the moving plate is sequentially connected to the liquid outlet hole 2102 of the fixed plate, and the liquid outlet hole 2102 of the fixed plate is connected to a liquid outlet pump. Therefore, when the leaching bin 17 rotates to the lower side of the feed hole 1204, the concentration of effective components in the extractant at the upper part of the leaching bin 17 is the highest and close to saturation. At this time, the liquid outlet groove 2003 of the moving plate is connected to the liquid outlet hole 2102 of the fixed plate, and the high-concentration extractant is pumped out by the liquid outlet pump, which is convenient for the subsequent separation of effective components.
[0057] The lower side of the chassis 3 may not be provided with the liquid separation fixed plate 21 and the liquid separation movable plate 20. The lower end of each overflow pipe 4 is connected to a drain pipe, and each drain pipe is installed with a solenoid valve. A photoelectric switch is provided on the fixed plate 12, and the photoelectric switch and the feed hole 1204 are arranged on the same radius of the fixed plate 12, so that when the leaching bin 17 rotates to just below the feed hole 1204, the solenoid valve corresponding to the leaching bin 17 is opened to allow the high-concentration extract to flow out, and when the leaching bin 17 is offset from the feed hole 1204, the corresponding solenoid valve is closed.
[0058] A method for using the above-mentioned leaching device comprises the following steps:
[0059] Step 1) adding the crushed material and the extractant into each leaching bin 17 in turn;
[0060] The crushed material is added into the leaching bin 17 through the feed pipe, and the extractant is added into the leaching bin 17; the leaching bin 17 rotates synchronously with the rotation of the main shaft 13, so the material and the extractant are added into the leaching bin 17 one by one.
[0061] Step 2) extracting the mixed liquid from the upper part of each leaching chamber 17 and conveying it to the leaching chamber 17 of the same level and the bottom of the leaching chamber 17 at the rear side along the rotation direction of the main shaft 13;
[0062] The circulation pump 5 extracts the mixed liquid on the upper part of the leaching bin 17 through the overflow pipe 4, and transports the mixed liquid to the leaching bin 17 of the same level and the leaching bin 17 on the rear side along the rotation direction of the main shaft 13 through the liquid outlet pipe 9, thereby completing the self-circulation and countercurrent circulation of the mixed liquid. The mixed liquid is transported to the bottom of the corresponding leaching bin 17 through the liquid outlet pipe 9, ensuring that the mixed liquid is fully mixed with the material, and can also fully stir the material, thereby improving the effective component extraction rate and leaching speed of the material.
[0063] Step 3) Pump out the mixed liquid and material in the leaching chamber 17 after extraction, and add the crushed material to the leaching chamber 17 on the front side along the rotation direction of the main shaft 13, and add fresh extractant to the leaching chamber 17 on the rear side along the rotation direction of the main shaft 13.
[0064] When the leaching bin 17 rotates to the lower side of the liquid inlet hole 1202, the liquid inlet hole 1202 is connected to the corresponding delivery hole 1103 of the leaching bin 17, thereby replenishing fresh solvent for the leaching bin 17. When the leaching bin 17 rotates to the lower side of the output hole 1203 again, the delivery hole 1103 corresponding to the leaching bin 17 is connected to the output hole 1203, and the material and the mixed liquid are pumped out of the leaching bin 17 through the output pump. When the leaching bin 17 rotates to the lower side of the feed hole 1204 again, the delivery hole 1103 corresponding to the leaching bin 17 is connected to the feed hole 1204, thereby replenishing fresh material into the leaching bin 17. Continuous leaching is achieved, and the pumping in of materials and extractants and the pumping out of materials and mixed liquids can be achieved without stopping the machine. When the leaching bin 17 rotates to the lower side of the feed hole 1204, the concentration of effective components in the extractant at the upper part of the leaching bin 17 is the highest and close to saturation. At this time, the movable plate liquid outlet trough 2003 is connected with the fixed plate liquid outlet hole 2102, and the high-concentration extractant is extracted through the liquid outlet pump to facilitate the subsequent separation of effective components.
[0065] When the liquid inlet 1202, the output hole 1203 and the feed hole 1204 are connected to the delivery hole 1103 respectively, the delivery slot 1102 prolongs the connection time between the liquid inlet 1202, the output hole 1203 and the feed hole 1204 and the delivery hole 1103 respectively, thereby ensuring that there is enough time to complete the replenishment of the material and the extractant in the leaching chamber 17 and the pumping out of the material and the mixed liquid. The fixed plate liquid outlet slot 2003 also prolongs the connection time between the overflow hole 2002 and the fixed plate liquid outlet hole 2102, ensuring that the high-concentration extractant is completely pumped out.
[0066] Example 2
[0067] The difference between Example 2 and Example 1 is that the liquid outlet of the circulation pump 5 is connected to the bottom of the leaching chamber 17 at the rear side of the rotation direction of the main shaft 13 only through the countercurrent pipe 19, and the reflux pipe 7 is not provided in this embodiment.
[0068] Example 3
[0069] The difference between Example 3 and Example 1 is that the liquid outlet end of the circulation pump 5 is connected to the bottom of the leaching tank 17 of this stage only through the reflux pipe 7. In this embodiment, the countercurrent pipe 19 is not provided, and the liquid inlet hole 1202 and the feed hole 1204 are not provided on the fixed plate 12.
