Description

Technical Field

[0001] This invention relates to the technical field of rare earth resource recycling, specifically to a rare earth oxide waste residue recycling device. Background Technology

[0002] Rare earth elements are a collective term for 17 elements in the periodic table, including the lanthanides and scandium and yttrium, which are closely related to the lanthanides. They do not exist in the form of "earth" but are distributed in the earth's crust as minerals such as oxides or salts. They are named for the difficulty in extraction, similar properties, and separation in the early days. Rare earth elements have unique physicochemical properties, such as excellent photoelectric and electromagnetic properties and high catalytic activity. They are widely used in high-tech fields such as new energy, electronic information, aerospace, and national defense. They are an indispensable "vitamin" for modern industry and play a key role in promoting industrial upgrading and technological progress.

[0003] Rare earth processing equipment generates a large amount of rare earth oxide waste residue during production. This waste residue can be recycled and reused. Therefore, a device is needed to transfer the rare earth oxide waste residue between the processing equipment and the recycling equipment. Traditional rare earth oxide waste residue transfer devices mainly consist of a material box, a transfer frame, and a discharge mechanism. The material box directly holds the rare earth oxide waste residue. The transfer frame is made of metal and has rollers or rails at the bottom for easy movement within the workshop. Some designs are equipped with brakes to ensure safety when parked. The discharge mechanism is usually driven by a hydraulic or electric telescopic rod. It uses a mechanical arm or linkage mechanism to tilt the material box, achieving automatic discharge. The working principle is as follows: the material box of the rare earth oxide waste residue transfer device is placed at the slag outlet of the rare earth processing equipment to collect the rare earth oxide waste residue discharged from the slag outlet. After collection, the operator uses rollers to push the transfer frame to move the material box to the inlet of the recycling device, and then starts the discharge mechanism to tilt the material box to a specified angle for discharge, completing the transfer of the rare earth oxide waste residue.

[0004] However, traditional rare earth oxide waste transfer devices still face many problems in actual use. For example, the movement of traditional rare earth oxide waste transfer devices mainly relies on manual pushing of the material box. Although the traditional transfer device is equipped with rollers at the bottom, its movement, positioning, docking with the equipment, and adjustment of the unloading angle all depend heavily on manual operation. This results in high labor intensity, low efficiency, and the device is prone to shaking and collisions during movement, causing rare earth oxide waste to spill, resulting in resource waste and environmental pollution.

[0005] The purpose of this invention is to provide a rare earth oxide waste residue recycling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rare earth oxide waste residue recycling device, wherein a drive motor is fixedly installed on the outer surface of the supporting frame by bolts, a transmission screw is fixedly connected to the output end of the drive motor, a threaded seat is threadedly connected to the outer wall of the transmission screw, a movable plate is fixedly connected to the side of the threaded seat away from the transmission screw, an installation groove is formed on the upper surface of the movable plate, a connecting shaft is fixedly connected to the inner side wall of the installation groove, a rotating plate is rotatably connected to the outer wall of the connecting shaft, a collection hopper is fixedly connected to the rotating plate away from the installation groove, and a rack and pinion assembly is fixedly connected to the inner side wall of the supporting frame.

By driving the transmission screw to rotate through the drive motor, the movable plate and the collection bucket are moved, realizing the automatic movement of the collection bucket. When the collection bucket moves to the inlet of the recycling device, the meshing of the gear and the adjusting rack makes the collection bucket rotate automatically during the movement, changing the tilt angle to unload the material. No manual pushing is required, which greatly reduces the labor intensity and avoids the shaking and collision problems that may occur during manual pushing. 2.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-8 The present invention provides a technical solution: a rare earth oxide waste residue recycling device, including a support frame 1, a drive motor 2 fixedly mounted on the outer surface of the support frame 1 by bolts, a transmission screw 4 fixedly connected to the output end of the drive motor 2, a threaded seat 11 threadedly connected to the outer wall of the transmission screw 4, a movable plate 6 fixedly connected to the side of the threaded seat 11 away from the transmission screw 4, an installation groove 18 opened on the upper surface of the movable plate 6, a connecting shaft 19 fixedly connected to the inner side wall of the installation groove 18, a rotating plate 20 rotatably connected to the outer wall of the connecting shaft 19, a collection hopper 7 fixedly connected to the rotating plate 20 away from the installation groove 18, and a rack assembly 10 fixedly connected to the inner side wall of the support frame 1.

[0021] According to the appendix Figure 1-3 As shown, in the process of collecting rare earth oxide waste residue, the drive motor 2 on the outer surface of the support frame 1 is started first. The output end of the drive motor 2 drives the transmission screw 4 to rotate. The transmission screw 4 drives the movable plate 6 to move along the guide slide rod 8 to the slag outlet of the rare earth processing equipment through the threaded seat 11. At the same time, the movable plate 6 drives the collection bucket 7 to move. The roller 15 on the collection bucket 7 rolls on the inner wall of the sliding groove 9 to ensure the stability of the movement of the collection bucket 7. When the collection bucket 7 moves to the slag outlet of the rare earth processing equipment, the rare earth oxide waste residue discharged from the slag outlet of the rare earth processing equipment is collected through the collection bucket 7.

[0022] The drive motor 2 is the power source of the device. Its output drives the transmission screw 4 to rotate, providing power for the movement of the movable plate 6 and the collection bucket 7. By controlling the forward and reverse rotation of the drive motor 2, the reciprocating movement of the collection bucket 7 can be realized.

[0023] Combined with the appendix Figure 4-5 As shown, two mounting plates 17 are fixedly connected to the side of the collection hopper 7 near the movable plate 6. The two mounting plates 17 are symmetrically arranged. A first mounting shaft 13 is fixedly connected to the side of the mounting plate 17 away from the movable plate 6. A gear 14 is fixedly connected to the outer wall of the first mounting shaft 13. A second mounting shaft 16 is fixedly connected to both sides of the collection hopper 7. A roller 15 is rotatably connected to the side of the second mounting shaft 16 away from the collection hopper 7. A counterweight 21 is fixedly connected to the side of the collection hopper 7 near the roller 15 by bolts. Two sliding grooves 9 are opened on the upper surface of the bearing frame 1. The two sliding grooves 9 are symmetrically arranged. The roller 15 is slidably installed on the inner wall of the sliding groove 9. A fixed bearing 5 is fixedly connected to the inner wall of the bearing frame 1. The end of the transmission screw 4 away from the drive motor 2 is fixedly installed on the inner ring of the fixed bearing 5. Two guide slide rods 8 are fixedly connected to the inner wall of the bearing frame 1. Guide slide blocks 12 are fixedly connected to both sides of the movable plate 6.

[0024] The counterweight 21 is used to make the collecting hopper 7 tend to return to its initial position after unloading or when it is unloaded. After collecting the waste residue, the drive motor 2 is started to rotate the transmission screw 4 in the opposite direction. The transmission screw 4 drives the movable plate 6 to move along the guide slide rod 8 to the inlet of the recycling device through the threaded seat 11, thereby moving the collecting hopper 7 to the inlet of the recycling device. When the collecting hopper 7 moves to the inlet of the recycling device, the gear 14 fixedly connected on the first mounting shaft 13 on both sides of the collecting hopper 7 meshes with the adjusting rack 1004 in the rack assembly 10. During the meshing process, as the movable plate 6 continues to move, the collecting hopper 7 drives the rotating plate 20 on the lower surface to rotate around the connecting shaft 19, causing the collecting hopper 7 to rotate. The roller 15 on its side then disengages from the bottom surface of the sliding groove 9, and the tilt angle of the collecting hopper 7 changes, causing the rare earth oxide waste residue to slide out along the side wall of the collecting hopper 7 and fall into the inlet of the recycling device.

[0025] Combined with the appendix Figure 1 As shown, the guide slide 12 is slidably connected to the outer wall of the guide slide rod 8. Both sides of the bearing frame 1 are fixedly connected to a set of fixed ear plates 3. The two sets of fixed ear plates 3 are symmetrically arranged, and there are two fixed ear plates 3 in each set. The upper surface of the fixed ear plate 3 is provided with a through hole.

[0026] By using bolts or other fasteners through the mounting holes on the fixed ear plate 3, the bearing frame 1 can be securely installed between the rare earth processing equipment and the rare earth oxide waste residue recycling equipment, ensuring that the device is firmly installed and providing a stable foundation for subsequent operations.

[0027] Combined with the appendix Figure 6 As shown, the rack assembly 10 includes a mounting base 1001 fixedly connected to the inner side wall of the support frame 1. A T-slot 1002 is formed on the outer side wall of the mounting base 1001. A T-shaped connecting plate 1003 is slidably connected to the inner wall of the T-slot 1002. A rack 1004 is fixedly connected to the side of the T-shaped connecting plate 1003 away from the T-slot 1002. A threaded groove 1005 is formed through the outer surface of the mounting base 1001. The threaded groove 1005 communicates with the T-slot 1002. A threaded rod 1007 is threadedly connected to the inner wall of the threaded groove 1005. A knob 1006 is fixedly connected to the end of the threaded rod 1007 away from the threaded groove 1005. Three rotating plates are fixedly connected to the outer wall of the knob 1006. The three rotating plates are arranged in a circular array. A fixed through hole 1008 is formed through the side of the T-shaped connecting plate 1003 near the threaded groove 1005. The fixed through hole 1008 facilitates the threaded rod 1007 to pass through.

[0028] The worker rotates the threaded rod 1007 by holding the screwing plate, disengaging it from the fixing through hole 1008 on the T-shaped connecting plate 1003. Part of the threaded rod 1007 is still in the threaded groove 1005. At this time, the T-shaped connecting plate 1003 is pulled out of the T-groove 1002, and the T-shaped connecting plate 1003 of the new rack 1004 is slid into the T-groove 1002. The threaded rod 1007 is then tightened in the reverse direction, and the rack 1004 can be disassembled and replaced.

[0029] Combined with the appendix Figure 7 As shown, a movable groove 1011 is provided through the outer wall of the T-shaped connecting plate 1003. A movable rod 1012 is slidably connected to the inner wall of the movable groove 1011. A pull plate 1013 is fixedly connected to one end of the movable rod 1012 away from the T-shaped connecting plate 1003. A limit block 1009 is fixedly connected to one end of the movable rod 1012 away from the pull plate 1013. The limit block 1009 is located directly above the rack 1004. A brush bristle 1010 is fixedly connected to the side of the limit block 1009 near the rack 1004.

[0030] The limiting block 1009 can be used to temporarily block the gear 14. Simultaneously, the operator can hold the pull plate 1013 and reciprocate to slide the movable rod 1012 against the inner wall of the movable groove 1011, causing the limiting block 1009 to reciprocate above the rack 1004. The brush bristles 1010 below the limiting block 1009 can clean the rack 1004, preventing jamming when the rack 1004 meshes with the gear 14 and ensuring the normal operation of the device. Although the illustrative embodiments of this application have been described above to enable those skilled in the art to understand this application, this application is not limited to the scope of the specific embodiments. For those skilled in the art, all inventions utilizing the concept of this application are protected as long as various modifications fall within the spirit and scope defined and determined by the appended claims.
