Description

Technical Field

[0001] This invention relates to a copper swirl flotation raw material loading device, belonging to the field of copper smelting technology. Background Technology

[0002] In the traditional copper swirl flotation process, the loading of raw materials for swirl flotation is mainly achieved through the following steps: Copper matte powder, fumes, and solvent → collecting scraper conveyor → No. 1 feed chute → No. 1 vulcanizer. No. 1 vulcanizer splits into two paths: one path goes to No. 2 feed chute → No. 2 vulcanizer, and the other path goes to No. 3 feed chute → No. 3 vulcanizer. Finally, No. 2 and No. 3 vulcanizers output to the vortex nozzle material channel.

[0003] This loading method has the following drawbacks: When the material moves in the No. 1 feed chute, due to its non-ideal fluid nature, the material layer is unstable, causing the material to flow tightly against the bottom of the chute. After entering the No. 1 vulcanizer, the material cannot be evenly distributed, resulting in uneven material distribution into the No. 2 and No. 3 feed chutes. Subsequently, the material continues to flow along the bottom of the pipes in the No. 2 and No. 3 chutes, entering one end of the No. 2 and No. 3 vulcanizers respectively, where uneven material distribution again occurs. Ultimately, the uneven distribution of material when entering the material channel of the vortex nozzle will cause problems such as local adhesion at the bottom of the material channel of the vortex nozzle, reduced reaction efficiency, and localized overheating of the reaction tower masonry.

[0004] To address the aforementioned issues, the existing improvement plan involves eliminating fluidizer No. 1 and replacing it with a pneumatic chute. While this method allows for uniform material distribution when entering chutes No. 2 and No. 3, it still fails to achieve uniform distribution within fluidizers No. 2 and No. 3. Consequently, issues with the blowing reaction and potential safety hazards in the furnace remain, necessitating further improvements. Summary of the Invention

Detailed Implementation

[0019] The present invention will now be described in more detail with reference to the embodiments.

[0020] Example 1 Please see Figures 1 to 5 The copper swirl flotation raw material loading device in this embodiment includes a conveyor 200, a third fluidizer 10, and a fourth fluidizer 11.

[0021] In this embodiment, the output end of the conveyor 200 is provided with a feed inlet 1. A baffle plate is provided at the feed inlet 1 to separate the inlet of the first discharge pipe 2 and the inlet of the second discharge pipe 3. After the material is conveyed by the conveyor 200, it can fall into the first discharge pipe 2 and the second discharge pipe 3 respectively after being blocked by the baffle plate.

[0022] In this embodiment, the materials are mainly copper matte powder, fume, and flux.

[0023] The feed inlet 1 is connected to the first feed pipe 2 and the second feed pipe 3, which are symmetrically arranged. The first feed pipe 2 is equipped with a first fluidizer 201 on the side of its bottom end, and the second feed pipe 3 is equipped with a second fluidizer 301 on the side of its bottom end.

[0024] Specifically, the output end of fluidizer 201 is connected to a material conveying assembly 1 and a material conveying assembly 2, which are arranged in parallel.

[0025] The output ends of the first and second conveying components are symmetrical and both are connected to the third fluidizer 10. The output ports of the first and second conveying components are positioned directly opposite the middle of the third fluidizer 10.

[0026] The output of fluidizer 301 is connected to conveying assembly three and conveying assembly four, which are arranged in parallel.

[0027] Among them, the output ends of the three conveying components and the four conveying components are symmetrical to each other and are both connected to the fourth fluidizer 11. The output ports of the three conveying components and the four conveying components are set directly opposite the middle of the fourth fluidizer 11.

[0028] The output ends of fluidizer No. 3 10 and fluidizer No. 4 11 are both connected to the material channel 16 of the swirling nozzle.

[0029] Specifically, the first material conveying assembly includes a third discharge pipe 5 and a seventh discharge pipe 13 connected in sequence, and the second material conveying assembly includes a fourth discharge pipe 6 and a eighth discharge pipe 12 connected in sequence. Feed pipes 5 and 6 are arranged symmetrically to each other, and feed pipes 13 and 12 are arranged symmetrically to each other.

[0030] Furthermore, the material conveying assembly three includes a sixth discharge pipe 8 and a tenth discharge pipe 15 connected in sequence, and the material conveying assembly four includes a fifth discharge pipe 7 and a ninth discharge pipe 14 connected in sequence; Feed pipes 7 (No. 5) and 8 (No. 6) are arranged symmetrically, as are feed pipes 14 (No. 9) and 15 (No. 10). In this embodiment, a fork-type feeding device 4 is provided between the output end of fluidizer 201 and the third and fourth feeding pipes 5 and 6; a fork-type feeding device 4 is provided between the output end of fluidizer 301 and the fifth and sixth feeding pipes 7 and 8.

[0031] The forklift feeding device 4 is mainly used to evenly divide the downward-inputting material, so that the material is precisely divided into two again.

[0032] The working principle of this embodiment is that the material can be initially evenly distributed by setting up the first feeding pipe 2 and the second feeding pipe 3 symmetrically. After the material enters the first feeding pipe 2 and the second feeding pipe 3 respectively, it can slide down along the pipe wall of the first feeding pipe 2 and the second feeding pipe 3. Then it is stopped by the corresponding first fluidizer 201 and second fluidizer 301. Then the fluidizing air leading to the first fluidizer 201 and the second fluidizer 301 fluidizes the material and then continues to be conveyed downward.

[0033] The following process takes the conveying path of fluidizer 201 as an example. After passing through fluidizer 201, the material is precisely separated by the fork feeder 4 and continues to be conveyed downwards into the symmetrically arranged feed pipes 5 and 6.

[0034] The materials in feed pipes 5 and 6 continue to be conveyed downwards. Specifically, the materials in feed pipe 5 are conveyed to feed pipe 13, and the materials in feed pipe 6 are conveyed to feed pipe 12.

[0035] Please see Figure 4 and Figure 5 After adjusting the positions of feed pipe 13 (No. 7) and feed pipe 12 (No. 8), the material can be aligned. Figure 5 At point B, the material from feed pipes 13 and 12 falls into the center of fluidizer 10 in an opposing, crisscross pattern and is then stopped.

[0036] Finally, after being fluidized by the fluidizing air introduced into the No. 3 fluidizer 10, the material enters the material channel 16 of the swirl nozzle evenly.

[0037] Meanwhile, in the same way, the material in the second fluidizer 301 falls into the fourth fluidizer 11 in an opposing and cross-shaped manner, and finally enters the material channel 16 of the swirling nozzle evenly after fluidization.

[0038] With the above settings, the material is distributed evenly in stages, and then the fluidizer's fluidization function achieves uniform distribution at the material channel outlet.

[0039] Furthermore, an air inlet pipe for introducing air and oxygen into the material channel 16 of the swirling nozzle is provided between the No. 3 fluidizer 10 and the No. 4 fluidizer 11, and an air inlet 9 is provided on the air inlet pipe.

[0040] Example 2 Please see Figures 6 to 12 In this embodiment of the copper swirl flotation raw material loading device, based on the above embodiment one, an anti-caking device 100 is provided between the feed inlet 1 at the top of the first feed pipe 2 and the second feed pipe 3 and the conveyor 200.

[0041] Specifically, the anti-caking device 100 includes an impact barrel 245, the top of which is connected to the output end of the conveyor 200 via a connecting hose 21, and the bottom of which is connected to the inlet 1 via a connecting hose 21; the anti-caking device 100 also includes a drive assembly for driving the impact barrel 245 to swing.

[0042] Furthermore, the drive assembly includes a swing frame 22 and a connecting frame 23. The connecting frame 23 is fixedly connected to the impact barrel 245. The swing frame 22 includes an inverted U-shaped frame 221. A swing frame 224 is provided at the bottom of the U-shaped frame 221. A drive motor is installed at the top of the U-shaped frame 221. The drive shaft 222 of the drive motor rotates through the U-shaped frame 221 and is fixedly sleeved with a drive plate 226. An oblique shaft 2261 is fixedly connected to the free end of the drive plate 226. A swing block 225 is movably connected inside the swing frame 224. The swing block 225 is fixedly connected to the free end of the oblique shaft 2261. Movable rods 223 are fixedly connected to both ends of the swing frame 224. The movable rods 223 are rotatably connected to the side wall of the U-shaped frame 221, and one of the movable rods 223 rotates through the side wall of the U-shaped frame 221 and is fixedly connected to the connecting frame 23.

[0043] In this embodiment, the driving motor drives the driving shaft 222 to rotate, which in turn drives the driving plate 226 to rotate. Since the driving plate 226 is equipped with an inclined shaft 2261, and the inclined shaft 2261 is inclined, the inclined shaft 2261 can drive the swing block 225 to swing. Since the swing block 225 is movably installed in the swing frame 224, under the driving force of the driving motor, the swing block 225 can swing in the swing frame 224 and synchronously drive the swing frame 224 to swing.

[0044] Due to the swing of the swing frame 224, the entire connecting frame 23 can be shaken by the movable rod 223. The material will be broken up by the impact barrel 245 when it enters the impact barrel 245, which can prevent clumping and avoid subsequent blockage or uneven reaction.

[0045] Furthermore, the connecting frame 23 includes a T-shaped plate 231, and one end of the movable rod 223 extending out of the U-shaped frame 221 is fixedly connected to the T-shaped plate 231; several fixed shafts 241 are vertically inserted through the T-shaped plate 231, and the top and bottom ends of each fixed shaft 241 are fixedly connected to a mounting plate 242. The free ends of the two mounting plates 242 are integrally connected with annular sleeves 244, and the impact barrel 245 is fixedly sleeved between the two annular sleeves 244. At the same time, a fixed frame 243 is provided at the top of the T-shaped plate 231 and fastened to the top of the movable rod 223. The end of the movable rod 223 extending out of the U-shaped frame 221 is fixedly connected to one of the fixed shafts 241. The modular design of the connecting frame 23 facilitates disassembly, assembly, and maintenance.

[0046] Furthermore, the top of the T-shaped plate 231 is provided with a fixing bracket 243 that is fastened to the top of the movable rod 223, and the end of the movable rod 223 extending out of the U-shaped bracket 221 is fixedly connected to one of the fixing shafts 241.

[0047] Furthermore, multiple impact cones 2451 are evenly arranged inside the impact barrel 245 to facilitate the breaking up of agglomerated materials.
