Description

Technical Field

[0001] The invention relates to the technical field related to crude cobalt acid raw materials, and specifically provides a crude cobalt acid raw material pretreatment device. Background Art

[0002] Crude cobalt carbonate is an important inorganic chemical raw material, widely used in industries such as batteries, glass and coatings.

[0003] The main raw material of crude cobalt carbonate is cobalt ore, and cobalt phosphate ore with a high cobalt content is generally used as the raw material. The second step is ore dressing and leaching. The cobalt phosphate ore is crushed, ground and other processes to remove impurities. The powdered cobalt phosphate ore is then leached using the sulfuric acid leaching method. The cobalt phosphate ore is reacted with dilute sulfuric acid to dissolve the cobalt in the sulfuric acid to form a solution. The third step is purification and precipitation. The cobalt sulfuric acid solution is purified to remove impurities. Generally, sodium carbonate or sodium hydroxide is added for neutralization reaction to convert the impurities into precipitates.

[0004] The above is the work of using crushed ore as raw material. The existing pretreatment device has low efficiency when performing fusion reaction, and the powder will float on the surface when poured into dilute sulfuric acid and adhere to the inside of the equipment, which will not only slow down the fusion efficiency, but also increase the fusion time and increase the subsequent precipitation working time, which is not conducive to efficient processing. For this reason, we need to make improvements. Summary of the invention

After rapid mixing, the precipitation work is further accelerated, and then the hose is inserted from the connecting pipe through the external transparent window to suck the external purified solution, and then the precipitate is discharged to complete the pretreatment of the crude acid cobalt raw material.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] like Figure 1-Figure 8 The crude acid cobalt raw material pretreatment equipment shown comprises: a frame 1, a base 4 is fixedly installed on the inner side of the frame 1, a mixing tank 9 is fixedly installed on the inner side of the base 4, a processing box 2 is connected and installed on the upper side of the inner side of the mixing tank 9, a pushing cylinder 10 is connected and installed on one end of the processing box 2, a fixed cylinder 7 is connected to the inner side of the processing box 2 away from the pushing cylinder 10, a second rotating shaft 19 is installed and rotated together inside the pushing cylinder 10, the processing box 2 and the fixed cylinder 7, a driving mechanism is arranged at one end of the second rotating shaft 19, a de-impurity mechanism is arranged on the inner side of the processing box 2, a de-impurity pipe 8 is connected and installed inside the fixed cylinder 7, a first rotating shaft 17 is arranged on the inner side of the mixing tank 9, and discharge pipes 18 are connected and installed at both ends of the inner bottom of the mixing tank 9, the outer side of the first rotating shaft 17 is rotatably connected inside the mixing tank 9 through a fixing member, a fixed sleeve is fixedly connected to the outer side of the first rotating shaft 17, movable components are arranged on the outer sides of the fixed sleeve, a rotating component is arranged on the lower side of the outer side of the first rotating shaft 17, and a feed hopper 3 is connected and installed on the upper side of the inner side of the pushing cylinder 10.

[0029] The driving mechanism includes a pulley driving member 5 fixedly mounted on the outside of one end of the second rotating shaft 19, the pulley driving member 5 includes two sets of transmission wheels, a belt, and a housing, the output end of the pulley driving member 5 is connected to the first motor 6, the first motor 6 is fixedly arranged on the outside of the pulley driving member 5, the two sets of transmission wheels are respectively mounted on the first motor 6 and the outside of the second rotating shaft 19, the two sets of transmission wheels are connected by belts, and thus the first motor 6 can drive the second rotating shaft 19 to rotate.

[0030] The impurity removal mechanism includes an arc-shaped impurity removal net 25, both ends of which are installed between the pushing cylinder 10 and the fixed cylinder 7 through fixed plates 26 respectively, and material blocking members are provided on both sides of the edge of the arc-shaped impurity removal net 25. A connecting cylinder 24 is provided outside the second rotating shaft 19 and inside the arc-shaped impurity removal net 25, and swing rods 14 are installed at equal distances along the circumferential direction outside the connecting cylinder 24. Driven by the second rotating shaft 19, the multiple swing rods 14 outside the connecting cylinder 24 cause the multiple swing rods 14 to rotate, thereby flipping and moving the material inside the arc-shaped impurity removal net 25 to perform impurity removal operations. A spiral impeller 27 is fixedly installed outside the second rotating shaft 19 and inside the pushing cylinder 10. The drive of the second rotating shaft 19 can cause the spiral impeller 27 to automatically push the material into the arc-shaped impurity removal net 25.

[0031] The material blocking member includes an inclined plate 13 fixedly installed on the edge of the arc-shaped impurity removal net 25. The inclined plate 13 is fixedly installed on the inner wall of the processing box 2 on the side away from the arc-shaped impurity removal net 25.

Under the connection of the support rod 12, the first rotating shaft 17 can rotate more stably inside the mixing tank 9.

[0033] The movable component includes a fixed frame 23 fixedly mounted on one side of the fixed sleeve, a cross bar 28 is slidably mounted on the outer side of the fixed frame 23, support columns 29 are symmetrically mounted on the upper surface of the cross bar 28, clamping blocks 30 are fixedly mounted on the upper inner sides of the two support columns 29, and multiple steel needles 31 are installed on the upper surfaces of the two clamping blocks 30, a sliding rod 36 is slidably inserted into the inner side of the cross bar 28, and a spring 37 is mounted on the outer side of the sliding rod 36, and the two ends of the spring 37 are respectively connected to the outer sides of the fixed frame 23 and the cross bar 28. As the cross bar 28 rotates synchronously with the first rotating shaft 17, the end of the cross bar 28 is in active contact with the abutment block 33, so that the cross bar 28 moves up and down on the outer side of the fixed frame 23 under the elastic pressure of the spring 37, thereby the steel needles 31 on the upper surface of the clamping block 30 can move up and down to stir the powder at the liquid surface and reduce the floating surface of the powder.

[0034] The rotating assembly includes a reinforcing rod 35 installed on the outside of the first rotating shaft 17, and a gear ring 34 is commonly installed at the ends of multiple reinforcing rods 35. Support rods 39 are installed at equal distances along the circumferential direction on the inner wall of the mixing tank 9. Multiple support rods 39 can stably install the gear ring 34 on the outside of the first rotating shaft 17 for use. A connecting shaft 20 is rotatably inserted at one end of the inner side of the support rod 39, and a gear 38 is fixedly sleeved on the outside of the connecting shaft 20. The gear 38 is meshed with the gear ring 34. A rotary vane 21 is fixedly installed at the lower outside of the connecting shaft 20. The drive of the first rotating shaft 17 causes the outer gear ring 34 to rotate, causing the gear ring 34 to mesh with the multiple sets of gears 38 on the outside, thereby allowing the connecting shaft 20 and the outer rotary vane 21 to perform mixing work at different positions inside the mixing tank 9.

[0035] A ring plate 22 is fixedly installed on the upper inner side of the mixing tank 9, and blocks 33 are installed on the upper surface of the ring plate 22 at equal distances along the circumferential direction. The edges on both sides of one end of the cross bar 28 are processed into curved surfaces 32 and are in active contact with the blocks 33. The curved surface 32 is set on the edge of the cross bar 28 to cooperate with the blocks 33 for sliding and pressing.

[0036] A transparent window 16 is installed inside the mixing tank 9, and a connecting pipe 15 is installed inside the transparent window 16. The transparent window 16 is convenient for observing the sediment at the bottom of the tank, and then convenient for inserting a hose to suck the purified solvent.

[0037] Working principle: When in use, the dilute sulfuric acid solvent is first pumped into the mixing tank 9, and then the material is processed. The material enters the push barrel 10 through the feed hopper 3, and the first motor 6 drives the pulley drive member 5 to drive the second shaft 19 to rotate, pushing the spiral impeller 27 at the push barrel 10 to rotate, and automatically pushes the material to the arc-shaped impurity removal net 25 at the processing box 2. The multiple swing rods 14 on the outside of the connecting tube 24 flip and toggle the inside to remove impurities from the material. The impurities are discharged through the impurity removal pipe 8 at one end, and the material falls into the mixing tank 9 through the arc-shaped impurity removal net 25 and contacts with the dilute sulfuric acid solvent. At this time, the second motor 11 rotates to drive the first shaft 17 to rotate, and the corresponding outer fixed frame 23 drives the cross bar 28 to rotate. During the rotation of the cross bar 28 The end is in active contact with the block 33, so that the cross bar 28 moves up and down on the outside of the fixed frame 23 under the elastic pressure of the spring 37, and the steel needle 31 on the upper surface of the clamping block 30 can move up and down to stir the powder at the liquid surface and reduce the floating surface of the powder. The drive of the first rotating shaft 17 also causes the outer gear ring 34 to rotate, causing the gear ring 34 and the multiple sets of gears 38 on the outside to engage with each other, so that the connecting shaft 20 and the outer vane 21 are mixed at different positions inside the mixing tank 9 to increase the mixing rate. After rapid mixing, the precipitation work is further accelerated, and then the hose is inserted from the connecting pipe 15 through the external transparent window 16 to suck the external purified solution, and then the precipitate is discharged to complete the pretreatment of the crude acid cobalt raw material.
