Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of zirconium and hafnium separation, and particularly relates to a pretreatment device for zirconium and hafnium production. BACKGROUND

[0002] Zirconium and hafnium separation refers to separating zircon and hafnium from raw materials mixed together through appropriate chemical and physical methods. At present, due to the fact that the feeding mechanism cannot accurately control the feeding amount and feeding speed of the raw materials, the raw materials may be too much or too little to enter the separation device, thereby affecting the separation effect and production efficiency.

[0003] To solve the above problems, the feeding mechanism of the zirconium and hafnium separation device disclosed in Chinese Patent No. CN221275853U includes a U-shaped plate, a feeding pipe, a driving device, and a limiting block. The U-shaped plate has the feeding pipe rotatably installed on the inner side wall. The driving device is installed on the outer wall of one side of the U-shaped plate and can drive the feeding pipe to rotate. The limiting block is arranged on the inner wall of the end port of the feeding pipe. The second electric telescopic rod is fixedly installed on the bottom wall of the end of the feeding pipe close to the limiting block. The limiting block at the end of the second electric telescopic rod is connected. The limiting block close to one side of the U-shaped plate is provided with a concave arc surface. The device drives the first electric telescopic rod to rotate the gear through the rack, and then drives the feeding pipe to rotate through the transmission shaft. The end of the limiting block faces downward. The size of the discharge port of the feeding pipe is controlled by moving the limiting block forward and backward through the second electric telescopic rod, so as to control the discharge amount of the zirconium and hafnium raw materials.

[0004] The above-mentioned device has the following problems in actual use: when the device is used, due to the different sizes of the raw materials, the adjacent two raw materials are easily stuck and accumulated into a group during the movement of the raw materials in the feeding pipe. As the number of stuck raw materials gradually increases, the raw materials will block the feeding pipe, so that the raw materials cannot be discharged in the feeding pipe, causing inconvenience in use. SUMMARY

[0005] The present application provides a pretreatment device for zirconium and hafnium production to solve the problem that the existing feeding mechanism cannot clean the raw materials blocked in the feeding pipe during the discharge of the raw materials.

[0006] In order to achieve the above object, the present application adopts the following technical scheme: A pretreatment device for zirconium hafnium production, comprising a cylinder body with an inlet and an outlet, and further comprising a discharging mechanism and a discharging cylinder with an open top; the discharging cylinder is fixedly connected with the cylinder body and communicates with the inlet; a plurality of discharging holes are equidistantly arranged on the bottom of the discharging cylinder along the circumferential direction of the discharging cylinder; the discharging mechanism comprises a base plate, a side block, a sliding block, an elastic sector plate, a fixing block, a guide block, an edge block, a plurality of long blocks equidistantly fixedly connected with the base plate along the circumferential direction of the base plate, an annular groove arranged on the cylinder body, a bottom groove arranged on the side block, an edge groove arranged on the guide block, a bottom hole arranged on the base plate, a driving assembly for driving the base plate to rotate, a movement assembly for driving the sliding block to reciprocate along the length direction of the side block, and a power assembly for driving the edge block to vertically reciprocate; the long blocks are slidably connected with the annular groove; the side block is fixedly connected with the base plate; the sliding block is slidably connected with the sliding groove; the elastic sector plate is fixedly connected with the sliding block, and the through hole is located on the movement track of the elastic sector plate; the fixing block is fixedly connected with the side block; the guide block is fixedly connected with the fixing block; the edge block is slidably connected with the edge groove, and the elastic sector plate is located on the movement track of the edge block; and the bottom hole communicates with the discharging hole.

[0007] The principle and advantages of the present scheme are as follows: After the raw materials are put into the discharging cylinder through the inlet, the base plate is driven to rotate by the driving assembly. During the rotation of the base plate, when the bottom hole communicates with the discharging hole at different positions in turn, the raw materials can be sequentially discharged from different positions. That is, through the above movement, the raw materials can be sequentially and orderly discharged along the circumferential direction of the discharging cylinder, thereby improving the uniformity of the raw material discharge, enhancing the effect of the raw material discharge, and ensuring the quality of the raw material discharge.

[0008] During the communication between the bottom hole and the discharging hole, the elastic sector plate reciprocates along the length direction of the side block, and the elastic sector plate can adjust the aperture of the bottom hole during discharging, thereby controlling the amount of raw materials discharged from the bottom hole. Through the above movement, the discharging speed of the raw materials can be adjusted, so that the raw materials can be more uniformly and completely discharged. That is, the effect of the raw materials discharged from the bottom hole is further enriched, so that the raw materials can be sequentially discharged, and the quality of the raw material discharge is improved.

[0009] During the movement of the elastic sector plate, the edge block vertically reciprocates, and the elastic sector plate can be deformed. When the elastic sector plate is deformed, the elastic sector plate can drive the raw materials clamped in the bottom hole and the discharging hole to vertically reciprocate, thereby preventing the raw materials from being clamped in the bottom hole and the discharging hole, and ensuring that the raw materials can be more efficiently discharged through the discharging hole and the bottom hole. That is, through the above movement, the discharging effect of the discharging hole and the bottom hole is enhanced, and the discharging efficiency of the discharging hole and the bottom hole is improved.

[0010] Further, the dredging part is symmetrically arranged on both sides of the side block along the length direction of the side block; the dredging part comprises a screw rod, a guide rod, a nut seat, a flexible block and a power unit for driving the screw rod to rotate; the screw rod is rotationally connected with the base plate; the guide rod is fixedly connected with the base plate; the nut seat is threadedly connected with the screw rod and slidably connected with the guide rod; the flexible block is fixedly connected with the nut seat; the flexible block is located below the bottom hole and can slide in and out of the bottom hole.

[0011] Through the vertical reciprocating movement of the flexible block, the flexible block can slide in and out of the bottom hole, and the flexible block also has a certain force during the movement, so that the flexible block can further dredge the blocked raw materials in the bottom hole, so that the raw materials no longer adhere to the bottom hole. Through the above movement, the discharging efficiency and quality of the bottom hole can be further improved, that is, the raw materials can be efficiently discharged through the bottom hole.

[0012] Further, the dredging part further comprises a crushing unit; the crushing unit comprises a crushing shaft, a column block and a plurality of crushing blocks equidistantly arranged on the column block in the circumferential direction of the column block; the crushing shaft is fixedly connected with the screw rod; the column block is connected with the crushing shaft; and the crushing blocks are fixedly connected with the column block.

[0013] During the discharging of the raw materials, the crushing blocks rotate and crush the raw materials, so that the volume of the raw materials is reduced and the raw materials are crushed into a plurality of blocky particles, thereby preparing for the subsequent further processing of the raw materials. Through the above movement, the raw materials can be further processed during the falling of the raw materials, that is, the processing effect of the raw materials is enriched, and the efficiency of the pretreatment of the raw materials is ensured.

[0014] Further, the crushing unit further comprises an auxiliary part; the auxiliary part comprises an auxiliary block and a first spring; the auxiliary block is fixedly connected with the nut seat; the column block is slidably connected with the crushing shaft, the auxiliary block abuts against the column block; and the two ends of the first spring are connected with the crushing shaft and the auxiliary block, respectively.

[0015] Through the cooperation of the auxiliary block and the first spring, the column block can drive the crushing blocks to move vertically and reciprocally. The vertical and reciprocal movement of the crushing blocks can expand the crushing range of the raw materials, so that the crushing blocks can crush the raw materials at different positions, thereby further enriching the crushing effect of the raw materials and ensuring that the raw materials can be crushed more uniformly and completely.

[0016] Further, the linkage part comprises a linkage shaft, a plurality of linkage block groups equidistantly arranged in the axial direction of the linkage shaft and a linkage unit for driving the linkage shaft to rotate; the linkage shaft is rotationally connected with the fixed block; the linkage block group comprises a plurality of linkage blocks equidistantly arranged in the circumferential direction of the linkage shaft, and the linkage blocks are fixedly connected with the linkage shaft.

[0017] During the falling of the raw materials, the linkage block rotates, and then the linkage block can crush the raw materials from different directions, so that the raw materials can be subjected to the force from different directions, thereby the raw materials can be further crushed. That is, it ensures that the raw materials can be fully crushed under the joint action of the crushing block and the linkage block, and improves the crushing quality of the raw materials.

[0018] Further, the device further comprises a stirring and pressing part; the stirring and pressing part comprises a stirring and pressing shaft, a stirring and pressing block, a through hole opened on the bottom disc, a sliding hole opened on the bottom of the feeding cylinder, a driving unit for driving the stirring and pressing shaft to do vertical reciprocating motion; the stirring and pressing shaft is in sliding connection with the through hole, the stirring and pressing shaft passes through the sliding hole and extends into the feeding cylinder; the stirring and pressing block is fixedly connected with the stirring and pressing shaft, and the stirring and pressing block is located above the feeding hole.

[0019] During the rotation of the stirring and pressing block, the stirring and pressing block can stir the raw materials in the feeding cylinder, so that the raw materials can be more uniformly and more fully mixed, thereby enhancing the mixing effect of the raw materials and improving the mixing efficiency of the raw materials.

[0020] Further, during the rotation of the stirring and pressing block, the stirring and pressing block can also do vertical reciprocating motion, so that when the feeding hole is communicated with the bottom hole, the stirring and pressing block can promote the raw materials to do vertical downward motion, thereby the raw materials can be efficiently and quickly discharged through the feeding hole and the bottom hole, and the diversity of the raw material discharge is enriched. That is, through the above-mentioned motion, the discharge effect of the raw materials is enhanced, the discharge efficiency of the raw materials is improved, and the discharge quality of the raw materials is ensured.

[0022] During the rotation of the driving shaft, the first gear rotates synchronously. During the rotation of the first gear, the first annular rack drives the bottom disc to rotate due to the meshing connection between the first gear and the first annular rack.

[0023] Further, the motion assembly comprises a motion shaft, a first cam, a second spring, a second gear, and a second annular rack; the motion shaft is in rotational connection with the side block; the first cam and the second gear are fixedly connected with the motion shaft; the first cam is in abutment with the sliding block; the two ends of the second spring are connected with the sliding block and the bottom groove respectively; the second annular rack is fixedly connected with the cylinder body, and the second gear is in meshing connection with the second annular rack.

[0024] During the circumferential motion of the motion shaft along with the side block, the second gear drives the motion shaft to rotate through the meshing connection between the second gear and the second annular rack. Therefore, the motion shaft can rotate while doing circumferential motion.

[0025] During rotation of the motion shaft, the first cam rotates synchronously. During rotation of the first cam, when the convex part of the first cam abuts against the slider, the slider drives the elastic sector plate to move towards the position close to the bottom hole, and the second spring is compressed; when the convex part of the first cam abuts against the slider, the slider is reset under the action of the second spring, and the slider drives the elastic sector plate to move away from the position close to the bottom hole. Therefore, the slider can reciprocate along the length direction of the side block.

[0026] Further, the power assembly comprises a second cam and a third spring; the second cam is fixedly connected with the linkage shaft, and abuts against the side block; the two ends of the third spring are connected with the side block and the side groove respectively.

[0027] During rotation of the linkage shaft, the second cam rotates synchronously. During rotation of the second cam, when the convex part of the second cam abuts against the side block, the side block moves vertically upwards, and the third spring is compressed; when the second cam no longer abuts against the side block, the third spring drives the side block to reset, and the side block moves vertically downwards.

[0050] The movement shaft 28 is a worm. The linkage unit is a worm gear 36. The worm gear 36 is fixedly connected with the linkage shaft 20, and is engaged with the worm.

[0051] The driving unit comprises a third cam 37, a disc 38, and a fourth spring 39. The third cam 37 is fixedly connected with the linkage shaft 20. The disc 38 is fixedly connected with the stirring and pressing shaft 22, and the third cam 37 is fixedly connected with the disc 38. The fourth spring 39 is sleeved on the stirring and pressing shaft 22, and the two ends of the fourth spring 39 are connected with the disc 38 and the stirring and pressing shaft 22 respectively.

[0052] Specific implementation process: After the raw material is put into the feeding cylinder 2 through the inlet, the motor 27 is started, and the driving shaft 24 is driven to rotate by the output shaft of the motor 27. During the rotation of the driving shaft 24, the first gear 25 rotates synchronously. During the rotation of the first gear 25, the first annular rack 26 is driven to rotate due to the engagement between the first gear 25 and the first annular rack 26.

[0053] During the circumferential movement of the bottom disc 4, the side block 5 moves synchronously. During the movement of the side block 5, the worm moves synchronously. During the circumferential movement of the worm, the second gear 30 is driven to rotate by the engagement between the second gear 30 and the second annular rack 31. Therefore, the worm can rotate while moving circumferentially.

[0054] During rotation of the worm, the worm drives the worm gear 36 to rotate through engagement of the worm with the worm gear 36. During rotation of the worm gear 36, the linkage shaft 20 rotates synchronously. During rotation of the linkage shaft 20, the third cam 37 rotates synchronously. During rotation of the third cam 37, when the protruding part of the third cam 37 abuts against the disc 38, the disc 38 drives the stirring and pressing shaft 22 to move vertically upward, and the fourth spring 39 is compressed; when the protruding part of the third cam 37 no longer abuts against the disc 38, the fourth spring 39 drives the disc 38 to reset, and the disc 38 drives the stirring and pressing shaft 22 to move vertically downward. Therefore, while the stirring and pressing shaft 22 rotates with the base plate 4, the stirring and pressing shaft 22 can also move vertically reciprocally.

[0055] During rotation of the stirring and pressing block 23, the stirring and pressing block 23 can stir the raw materials in the feeding cylinder 2, so that the raw materials can be mixed more uniformly and more completely, thereby enhancing the mixing effect of the raw materials and improving the mixing efficiency of the raw materials.

[0056] Moreover, during rotation of the stirring and pressing block 23, the stirring and pressing block 23 can also move vertically reciprocally, so that when the feeding hole 3 communicates with the bottom hole, the stirring and pressing block 23 can promote the raw materials to move vertically downward, thereby the raw materials can be discharged through the feeding hole 3 and the bottom hole efficiently and quickly, and the diversity of the raw materials during discharging is enriched. That is, through the above movement, the discharging effect of the raw materials is enhanced, the discharging efficiency of the raw materials is improved, and the discharging quality of the raw materials is ensured.

[0057] During rotation of the base plate 4, when the bottom hole communicates with the feeding hole 3 at different positions in turn, the raw materials can be discharged from different positions in turn. That is, through the above movement, the raw materials can be discharged along the circumferential direction of the feeding cylinder 2 in turn and orderly, thereby the uniformity of the raw materials during discharging is improved, the effect of the raw materials during discharging is enhanced, and the quality of the raw materials during discharging is ensured.

[0058] During rotation of the worm, the first cam 29 rotates synchronously. During rotation of the first cam 29, when the protruding part of the first cam 29 abuts against the sliding block 6, the sliding block 6 drives the elastic sector plate 7 to move toward the position close to the bottom hole, and the second spring is compressed; when the protruding part of the first cam 29 no longer abuts against the sliding block 6, the sliding block 6 resets under the action of the second spring, and the sliding block 6 drives the elastic sector plate 7 to move away from the position close to the bottom hole. Therefore, the sliding block 6 can move reciprocally along the length direction of the side block 5.

[0059] During communication of the bottom hole with the feeding hole 3, the elastic sector plate 7 can adjust the aperture of the bottom hole during discharging through reciprocating movement along the length direction of the side block 5, thereby controlling the amount of the raw materials during discharging from the bottom hole. Through the above movement, the discharging speed of the raw materials can be adjusted, so that the raw materials can be discharged more uniformly and more completely. That is, the effect of the raw materials during discharging from the bottom hole is further enriched, the raw materials can be discharged orderly, and the discharging quality of the raw materials is improved.

[0060] During the rotation of the linkage shaft 20 and the second cam 32, when the raised portion of the second cam 32 abuts against the side block 10, the side block 10 moves vertically upward, compressing the third spring. When the second cam 32 no longer abuts against the side block 10, the third spring drives the side block 10 back to its original position, causing the side block 10 to move vertically downward. Thus, the side block 10 can perform vertical reciprocating motion.

[0061] During the movement of the elastic sector plate 7, the vertical reciprocating motion of the side block 10 causes the elastic sector plate 7 to deform. This deformation causes the elastic sector plate 7 to drive the material stuck in the bottom hole and the discharge hole 3 to perform vertical reciprocating motion, thereby preventing the material from becoming stuck in the bottom hole and the discharge hole 3, thereby ensuring that the material can be discharged more efficiently through the discharge hole 3 and the bottom hole. This movement enhances the discharge effect of the discharge hole 3 and the bottom hole, improving the discharge efficiency of the discharge hole 3 and the bottom hole.

[0062] During the movement of the slider 6, the rack 35 moves synchronously. During this movement, the rack 35 meshes with the third gear 34, which in turn drives the screw 12 to rotate. As the screw 12 rotates, the nut holder 14 is able to perform vertical reciprocating motion along the length of the guide rod 13. During this movement of the nut holder 14, the flexible block 15 also moves synchronously.

[0063] The flexible block 15 can slide in and out of the bottom hole through the vertical reciprocating motion. During the motion, the flexible block 15 also exerts a certain force, so that the flexible block 15 can further clear the raw materials blocked in the bottom hole, so that the raw materials no longer adhere to the bottom hole. Through the above motion, the material discharge efficiency and quality of the bottom hole can be further improved, that is, the raw materials can be efficiently discharged through the bottom hole.

[0064] During the material discharge, crushing shaft 16 rotates crushing block 18. This rotation breaks the material down, reducing its volume and breaking it into several lumpy particles, thus preparing it for further processing. This movement allows for further processing of the material while it is falling, thus enhancing the processing efficiency and ensuring efficient pre-processing.

[0065] During the movement of nut holder 14, auxiliary block 19 moves synchronously. During this movement, the interaction between auxiliary block 19 and the first spring enables column block 17 to drive crushing block 18 in vertical reciprocating motion. This vertical reciprocating motion of crushing block 18 expands the crushing range of the material, allowing it to crush different locations on the material, further enriching the crushing effect and ensuring more uniform and thorough crushing of the material.

[0066] As the raw material falls, the linkage block 21 is driven to rotate by the linkage shaft 20, thereby enabling the linkage block 21 to crush the raw material from different directions. As a result, the raw material is subjected to forces from different directions, which further crushes the raw material. This ensures that the raw material is fully crushed under the combined action of the crushing block 18 and the linkage block 21, thereby improving the crushing quality of the raw material.

[0067] In summary, the stirring and pressing of the raw material by the stirring and pressing block 23 enhances the material feeding effect. Furthermore, the bottom hole, which is sequentially connected to the discharge hole 3 at different locations, enables more uniform material feeding. During the material feeding process, the combined action of the elastic sector plate 7 and the flexible block 15 not only regulates the material feeding speed of the bottom hole, but also clears any material blockage within the bottom hole, thereby improving the material feeding efficiency. Finally, the combined action of the linkage block 21 and the crushing block 18 further enhances the pretreatment effect of the raw material and improves the quality of the raw material during subsequent processing.
