[0044] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0045] Embodiment 1

[0046] like Figures 1 to 11 As shown, a high-purity antimony rod preparation device described in an embodiment of the present invention includes a workbench 1, a first motor 2 is arranged on the upper surface of the workbench 1, a crushing box 3 is arranged on one side of the first motor 2, a fixed shaft 24 is fixedly connected to the output end of the first motor 2, and the fixed shaft 24 passes through the crushing box 3, a support block 21 passes through the middle of the fixed shaft 24, a plurality of rotating disks 211 are fixedly connected to the circumferential surface of the fixed shaft 24, and a plurality of hammer blocks 213 are rotatably connected between every two rotating disks 211, two first screens 6 are clamped in the crushing box 3, and the two first screens 6 are clamped with the same second screen 68, and the crushing box 3 is provided with a feed inlet 31 above, a discharge outlet is provided below the crushing box 3, and a collecting frame 5 is provided below the discharge outlet; a rotating plate 32 is rotatably provided on both sides of the crushing box 3; and two first support columns 22 are provided on the workbench 1, one side of each first support column 22 is fixedly connected to a second motor 23, the output end of each second motor 23 is fixedly connected to a reciprocating screw 26, the circumferential surface of each reciprocating screw 26 is slidably connected to a cleaning plate 27, and each cleaning plate 27 is abutted against the corresponding first screen 6, and the positions on both sides of the cleaning plate 27 corresponding to the reciprocating screw 26 are fixedly connected to telescopic sleeves 25.

[0047] Specifically, in the process of using the existing hammer mill to work, the raw materials entering the device are mainly crushed by the hammer, but in the process of crushing the antimony ore, some antimony ores have a high hardness and can be processed into suitable antimony ore particles after sufficient hammering, but some antimony ores have a certain viscosity. During the hammering and crushing process, they may adhere to the screen, so that the antimony ore will gradually accumulate on the screen, and then cause the screen to be blocked, thereby affecting the crushing efficiency of the equipment. Then, the screen needs to be cleaned separately, resulting in a decrease in the production efficiency of the antimony ore raw materials. Therefore, the present invention can clean the screen during the crushing of the antimony ore by setting a certain structure, thereby ensuring the crushing efficiency of the crusher;

[0048] First, the first motor 2 is started. The rotation of the first motor 2 will drive the fixed shaft 24 fixedly connected to its output end to rotate. The part of the fixed shaft 24 inside the crushing box 3 will also rotate, which will drive the fixed disk fixedly connected to the circumferential surface of the fixed shaft 24 to rotate. The rotation of several fixed disks will drive the hammer block 213 between every two fixed disks to rotate. The hammer block 213 is rotatably arranged between the two fixed disks. At the same time, the head of the hammer block 213 is too large to enter between the two rotating disks 211. Therefore, after the fixed shaft 24 drives the hammer block 213 to rotate, the hammer block 213 will be centrifugally swung, thereby continuously hammering and crushing the antimony ore, so that the antimony ore can be continuously hammered and shrunk. Then, after the antimony ore is crushed into particles that can pass through the screen, the antimony ore particles will flow into the collecting frame 5 along the discharge port;

[0049] At the same time, the rotation of the first motor 2 will also trigger a signal, thereby starting the two second motors 23. Each second motor 23 will drive the reciprocating screw 26 fixed to its output end to rotate. The rotation of the reciprocating screws 26 on both sides can drive the cleaning plates 27 set on the circumferential surface of each reciprocating screw 26. In the process of driving the cleaning plates 27 to slide, the cleaning plates 27 will continuously pull the telescopic sleeves 25 fixed to both sides thereof, and the telescopic sleeves 25 are sleeved on the reciprocating screws 26, so as to protect the reciprocating screws 26 and prevent the ore particles falling from above from falling onto the reciprocating screws 2 6, thereby the card column reciprocating screw 26, and then the reciprocating screw 26 rotates to make each cleaning plate 27 close to the screen and reciprocate, so as to clean the screen, and at the same time, the bottom ends of the two cleaning plates 27 are abutted against each other, and the cross-section of the two cleaning plates 27 is the same as the arc cross-section composed of the two first screens 6 and the second screen 68, that is, the cleaning of the two arc-shaped cleaning plates 27 can cover the three screens, achieving a better cleaning effect. At the same time, the cleaning brush of the cleaning plate is a wire brush, which can also push the ore blocks stuck in the mesh back into the crusher for crushing, achieving a better crushing effect.

[0050] As shown in the figure, in this embodiment, a first groove 212 is opened at the position of the inner wall of the crushing box 3 corresponding to the cleaning plate 27 , and the cleaning plate 27 can be embedded in the first groove 212 .

[0051] Specifically, during the use of the cleaning plate 27, when the screen needs to be replaced, the rotation of the first motor 2 can be controlled to drive the reciprocating screw 26, and the reciprocating screw 26 can drive the cleaning plate 27 to slide into the first trough body 212, thereby hiding the cleaning plate 27, thereby achieving the effect of facilitating the disassembly of the screen.

[0052] As shown in the figures and the figures, in this embodiment, a plurality of limiting rods 28 are fixedly connected to the inner wall of the first slot body 212 , and each limiting rod 28 passes through the cleaning plate 27 , and the cleaning plate 27 can slide along the limiting rod 28 .

[0053] Specifically, during the sliding process of the cleaning plate 27, in order to make the movement of the cleaning plate 27 more stable, a plurality of limit rods 28 are fixedly connected in each first groove body 212, and each limit rod 28 passes through the cleaning plate 27, so as to achieve the effect of making the cleaning plate 27 close to the screen for stable sliding.

[0054] As shown in the figure, in this embodiment, a plurality of limit rods 28 are distributed in a circular array around the two first screens 6 and the second screen 68, and each limit rod 28 is made of smooth alloy steel.

[0055] Specifically, the limit rods 28 are distributed in a circular array around the screen. At the same time, the limit rods 28 are made of smooth alloy steel and can support the screen. During the crushing process of the screen, the hammer block 213 squeezes the ore and the ore squeezes the screen, which enables the hammer block 213 to crush the ore better.

[0056] Embodiment 2

[0057] As shown in Figures 1 to 3, in contrast to Example 1, another embodiment of the present invention is as follows: two fixing plates 29 are fixedly connected to the top of the crushing box 3, and a connecting groove 63 is provided at the bottom end of each fixing plate 29, and a plug plate 61 is fixedly connected to the position of the first screen 6 corresponding to the connecting groove 63, and two slots 62 are provided on the surface of the plug plate 61, and the plug plate 61 can be inserted into the connecting groove 63, and a slide plate 66 is slidably provided at the position corresponding to each slot 62 on one side of the fixing plate 29, and the cross section of the slide plate 66 is in an inverted "U" shape, and a second slot body 64 is provided at the position of the fixing plate 29 corresponding to the slide plate 66, and two compression springs 65 are fixedly connected to the bottom wall of the second slot body 64, and one end of the two compression springs 65 away from the bottom wall of the second slot body 64 is fixedly connected to the slide plate 66, and a through slot 67 is provided at the top of the second slot body 64, and the slide plate 66 can slide upward along the through slot 67; and a block 610 fixedly connected to the bottom end of the second slot body 64, and slots 69 are provided at the positions of the two ends of the second screen 68 corresponding to the block 610.

[0058] Specifically, during the long-term use of the first screen 6 and the second screen 68, the first screen 6 and the second screen 68 will be constantly worn. When they are worn to a certain extent, the first screen 6 and the second screen 68 need to be replaced. At this time, the two slides 66 on each fixing plate 29 are pushed upward, so that one end of each slide 66 is disengaged from the slot 62 of the plug plate 61, and then the fixation of the two first screens 6 can be released, and then the first screen 6 is pulled upward, so that the block 610 at the bottom end of the first screen 6 is disengaged from the slot 69 of the second screen 68, and then the two first screens 6 and the second screens 68 are taken out from between the two limit rods 28 respectively, so that the disassembly of the screens can be completed, and then the screens can be replaced with new ones by the same operation, thereby achieving the effect of ensuring the production quality of the crusher.

[0059] As shown in the figure, in this embodiment, a guide plate 210 is electrically controlled at the feed port 31 of the crushing box 3 .

[0060] Specifically, after the antimony ore is put into the crushing box 3, the antimony ore can enter the crushing box 3 by controlling the electric control guide plate 210 to rotate, and then the guide plate 210 is controlled to rotate to the original position, which can shield the stones and dust splashed during the crushing process to a certain extent.

[0061] As shown in the figure, in this embodiment, an exhaust pipe 41 is fixedly connected to the outer wall of the crushing box 3 , and an end of the exhaust pipe 41 away from the crushing box 3 is fixedly connected to the bellows 4 , which is fixedly connected to the outer wall of the crushing box 3 .

[0062] Specifically, in the process of crushing antimony ore, there will inevitably be a large amount of ore particle dust. By fixing an exhaust pipe 41 to the outer wall of the feed port 31, and then fixing the exhaust pipe 41 to the bellows 4, the dust spreading from the feed port 31 can be collected. These dusts are also antimony ore particles. After a certain amount is collected, they can also be processed, thereby achieving the effect of solving resource problems.

[0063] As shown in the figure, two limit plates 53 are fixedly connected to the bottom of the collection frame 5 of this embodiment, and a limit groove 52 is opened at the position corresponding to each limit plate 53 on the workbench 1. The collection frame 5 can slide along the limit groove 52 through the limit plate 53, and a handle 51 is fixedly connected to the outer wall of the collection frame 5.

[0064] Specifically, after the collecting frame 5 collects a certain amount of antimony ore particles, by pulling the handle 51, the collecting frame 5 can slide out of the workbench 1 along the limiting groove 52 through the limiting plate 53, and then be transported to the next location for the remaining preparation steps.

[0065] A method for preparing a high-purity antimony rod, characterized in that the specific steps include:

[0066] Step 1: Prepare raw materials: collect ore with a high antimony content, and then use a high-purity antimony rod preparation device to crush the antimony ore. First, the ore enters the crushing box 3 from the feed port 31. After the antimony ore enters the crushing box 3, the electrically controlled guide plate 210 is rotated. The rotation of the guide plate 210 will guide the antimony ore into the crushing box 3. At this time, the first motor 2 drives a number of hammers 213 between every two rotating disks 211 to rotate, and then the hammers 213 will crush the antimony ore entering the crushing box 3. The successfully crushed antimony ore particles can pass through the first screen 6 and the second screen 68 from the feed port 54 to enter the collecting frame 5. After collecting a certain amount of antimony ore powder particles, the collecting frame 5 is taken out, and then the obtained antimony ore particles are leached using an acidic or alkaline leaching agent, so as to dissolve antimony from these antimony ore particles;

[0067] Step 2: Purification and precipitation: After the leached antimony is obtained, the antimony may still carry some metal ions, so it needs to be purified by solvent extraction or other methods to obtain a relatively pure antimony solution, and then the antimony is precipitated from the purified liquid to form a solid precipitate of antimony, and the precipitated antimony is filtered and separated;

[0068] Step 3: Smelting and casting: The obtained antimony precipitate is smelted to obtain high-purity antimony metal, and then the molten high-purity antimony metal is poured into a casting mold to obtain a high-purity antimony rod;

[0069] During the purification and precipitation process, the oxidant lead oxide is added, and then the impurities in the leached antimony are oxidized into slag to remove the impurities. Then, the precipitant is added to the antimony solution, stirred to make it fully mixed, and after the precipitate is formed, the precipitate is separated by filtering. After separation, a high-purity antimony precipitate is obtained;

[0070] The purification and precipitation process mainly involves adding an oxidant, lead oxide, and then oxidizing the impurities in the leached antimony into slag to remove the impurities. Then, a precipitant is added to the antimony solution and stirred to mix it thoroughly. After the precipitate is formed, the precipitate is separated by filtration. After separation, a high-purity antimony precipitate is obtained.

[0071] Working principle: first start the first motor 2. The rotation of the first motor 2 will drive the fixed shaft 24 fixedly connected to its output end to rotate. The part of the fixed shaft 24 inside the crushing box 3 will also rotate, which will drive the fixed disk fixedly connected to the circumferential surface of the fixed shaft 24 to rotate. The rotation of several fixed disks will drive the hammer block 213 between every two fixed disks to rotate. The hammer block 213 is rotatably arranged between the two fixed disks. At the same time, the head of the hammer block 213 is too large to enter between the two fixed disks. Therefore, after the fixed shaft 24 drives the hammer block 213 to rotate, the hammer block 213 will be centrifugally swung, thereby continuously hammering and crushing the antimony ore, so that the antimony ore can be continuously hammered and shrunk. Then, after the antimony ore is crushed into particles that can pass through the screen, the antimony ore particles will flow into the collecting frame 5 along the discharge port;

[0072] At the same time, the rotation of the first motor 2 will also trigger a signal, thereby starting the two second motors 23. Each second motor 23 will drive the reciprocating screw 26 fixedly connected to its output end to rotate. The rotation of the reciprocating screws 26 on both sides can drive the cleaning plates 27 set on the circumferential surface of each reciprocating screw 26. In the process of driving the cleaning plates 27 to slide, the cleaning plates 27 will continuously pull the telescopic sleeves 25 fixedly connected to both sides thereof, and the telescopic sleeves 25 are sleeved on the reciprocating screws 26, so as to protect the reciprocating screws 26 and prevent the ore particles falling from above from falling onto the reciprocating screws 26, thereby blocking the reciprocating screws 26, thereby cleaning the screen and protecting the reciprocating screws 26, extending the reciprocating screws 26. The cleaning plate 27 has a long service life, and the bottom ends of the two cleaning plates 27 are in contact with each other. The cross-section of the two cleaning plates 27 is the same as the arc cross-section composed of the two first screens 6 and the second screen 68, that is, the cleaning of the two arc-shaped cleaning plates 27 can cover the three screens, thereby achieving a better cleaning effect. During the sliding process of the cleaning plate 27, in order to make the movement of the cleaning plate 27 more stable, a plurality of limit rods 28 are fixedly connected in each first trough body 212, and each limit rod 28 passes through the cleaning plate 27, so as to achieve the effect of making the cleaning plate 27 close to the screen for stable sliding. At the same time, the cleaning brush of the cleaning plate is a wire brush, which can also push the ore blocks stuck in the mesh back into the crusher for crushing, thereby achieving a better crushing effect.

[0073] In addition, the limit rods 28 are distributed in a circular array around the screen. At the same time, the limit rods 28 are made of smooth alloy steel and can support the screen. During the crushing process of the screen, the hammer block 213 beats the ore, and the ore squeezes the screen, which can enable the hammer block 213 to crush the ore better.

[0074] During the long-term use of the first screen 6 and the second screen 68, the first screen 6 and the second screen 68 will be constantly worn. When they are worn to a certain extent, the first screen 6 and the second screen 68 need to be replaced. At this time, the two slide plates 66 on each fixing plate 29 are pushed upward, so that one end of each slide plate 66 is disengaged from the slot 62 of the plug plate 61, and then the fixation of the two first screens 6 can be released, and then the first screen 6 is pulled upward, so that the block 610 at the bottom end of the first screen 6 is disengaged from the slot 69 of the second screen 68, and then the two first screens 6 and the second screen 68 are taken out from between the two limit rods 28 respectively, so that the screens can be disassembled, and then the screens can be replaced with new ones by the same operation, thereby achieving the effect of ensuring the production quality of the crusher;

[0075] Finally, after the collecting frame 5 collects a certain amount of antimony ore particles, by pulling the handle 51, the collecting frame 5 can slide out of the workbench 1 along the limiting groove 52 through the limiting plate 53, and then be transported to the next location for the remaining preparation steps.

[0076] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
