Description

Technical Field

[0001] This invention belongs to the field of zirconia microsphere production technology, specifically relating to a waste removal device for recycling zirconia microsphere processing scraps. Background Technology

[0002] Zirconia microspheres, mostly composed of tetragonal zirconia (TZP), are also known as zirconia beads. During the production and processing of zirconia microspheres, substandard products are generated and need to be recycled for reprocessing to reduce resource waste. Inevitably, the recycled zirconia contains impurities, especially metallic impurities such as iron filings. These impurities are difficult to remove quickly and can negatively impact the subsequent reuse of the zirconia due to poor removal efficiency. Therefore, there is an urgent need for a zirconia microsphere processing waste recycling and impurity removal equipment to solve the above technical problems. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a purification device for recycling scrap materials from zirconia microsphere processing. The device includes a purification box with an inlet at the top and a discharge port with a switch valve at the bottom. A purification roller is installed inside the box, with one end connected to a motor that drives it to rotate. The purification roller is an electromagnetic roller, with one end connected to an external power source via a conductive slip ring. Multiple support plates are evenly distributed circumferentially along the roller in a radial pattern. The material requiring purification enters the purification box through the inlet and falls onto the purification roller. When the roller is energized, it generates magnetic attraction, adsorbing metallic impurities. The material, now free of impurities, falls from the purification box and is collected. After purification is complete, the roller is de-energized, losing its magnetic attraction, and the metallic impurities fall out under gravity.

[0004] Preferably, the feed inlet is equipped with a movable feed hopper via a moving component, and the moving direction of the feed hopper is parallel to the length direction of the impurity removal roller. The feed hopper moves continuously during feeding, ensuring that the material entering the impurity removal box falls evenly onto the impurity removal roller, increasing the usable area of ​​the roller and further improving the impurity removal effect and efficiency.

[0005] Preferably, the moving component one includes a linear module one, the outer wall of the feed hopper is fixedly connected to the slide of the linear module one, and the bottom of the feed hopper is connected to a discharge pipe, which extends into the feed inlet and faces the impurity removal roller. The linear module drives the feed hopper to move.

[0006] Preferably, the impurity removal roller is equipped with a scraping assembly, which includes a scraping frame. The scraping frame matches the impurity removal roller and the support plate. The scraping frame is sleeved on the scraping roller. The scraping frame is connected to a connecting assembly, which includes a moving ring and a connecting ring. The outer wall of the scraping frame is fixedly connected to the inner ring surface of the connecting ring. The outer ring surface of the connecting ring is rotatably connected to the inner ring surface of the moving ring through a bearing. A second moving component is fixedly connected to the outer ring surface of the moving ring. The second moving component drives the connecting assembly to reciprocate along the length of the impurity removal roller. The scraping frame scrapes off the metal impurities adhering to the impurity removal roller without affecting the next impurity removal operation.

[0007] Preferably, the second moving component includes a second linear module, and the top of the moving ring is connected to the second slide of the second linear module via a connecting rod, and the moving ring moves with the second slide.

[0008] Preferably, the second moving component includes a horizontal screw, a guide rod, and a second reversible motor. The horizontal screw and guide rod are arranged parallel to each other at the feed inlet. One end of the horizontal screw is connected to the second motor, which drives the horizontal screw to rotate in both directions. A slider is threaded onto the horizontal screw, and the slider is connected to the outer wall of the moving ring via a first fixing rod. A guide block is slidably fitted onto the guide rod, and the guide block is connected to the outer wall of the moving ring via the second fixing rod. The second motor drives the horizontal screw to rotate in both directions, and the slider drives the moving ring to reciprocate along the horizontal screw, causing the scraper frame to scrape away metal impurities from the removal roller.

[0009] Preferably, a receiving assembly is provided below the impurity removal roller. The receiving assembly includes a receiving plate, which is inclined along the length of the impurity removal roller. The lower end of the receiving plate has an openable and closable discharge port on the impurity removal box. The receiving plate is connected to a rotating assembly, which includes a rotating ring, a rotating shaft, and a motor. The central axis of the rotating ring and the rotating shaft coincides with the central axis of the impurity removal roller. The lower end of the receiving plate is fixedly connected to the rotating ring. The rotating ring is rotatably connected to the inner wall of the impurity removal box through a bearing. The rotating shaft is fixedly connected to the upper end of the receiving plate. The vertical distance from the upper end of the receiving plate to the central axis of the rotating shaft is greater than the radius of the moving ring, so that the receiving plate and the impurity removal roller do not interfere with each other and the receiving plate does not affect the rotation of the impurity removal roller. The rotating shaft passes through the impurity removal box and is connected to the motor, which drives the receiving plate to rotate. When the material enters the impurity removal box, the receiving plate is located on one side of the impurity removal roller, which will not affect the falling of the material after impurity removal. When the impurity removal roller needs to be cleaned, the feeding is stopped, the receiving plate rotates to the bottom of the impurity removal roller, the impurity discharge port opens, the impurity removal roller is de-energized, and the metal impurities fall off the impurity removal roller onto the receiving plate and are discharged from the impurity discharge port. After the impurity removal roller is cleaned, the receiving plate rotates back to the side of the impurity removal roller, and the feeding and impurity removal can continue. In the above process, the outlet of the material after impurity removal is different from that of the metal impurities. When the material and impurities are discharged alternately, there is no need to change the receiving device of the discharge port, which reduces labor and labor costs.

[0010] Preferably, the receiving plate is an arc-shaped plate, and the arc shape can reduce the falling of metal impurities.

[0011] This invention also includes other components that enable the normal operation of a waste removal device for recycling zirconia microsphere processing scraps, such as control components like motor one, motor two, linear module one, linear module two, and switching valves. These are all conventional techniques and equipment in the field. Furthermore, devices or components not limited in this invention, such as motors, horizontal screws, linear modules, and conductive slip rings, all employ conventional techniques and equipment in the field.

[0012] The present invention has the following beneficial effects: the metal impurities in the falling material are adsorbed by the impurity removal roller, and the adsorption of metal impurities is released by de-energizing the impurity removal roller, thereby realizing the separation of scrap and metal impurities, which is beneficial to the subsequent recycling process; the impurity removal effect is good and the efficiency is high.

[0016] The present invention will now be clearly described with reference to the accompanying drawings and specific embodiments. This description is merely illustrative and is not intended to limit the scope of the invention. Any modifications, equivalent substitutions, or improvements made by those skilled in the art based on the embodiments of the present invention without inventive effort to obtain all other embodiments should be included within the scope of protection of the present invention.

[0017] Example 1 like Figure 1-2As shown, this invention provides a waste removal device for recycling scrap from zirconia microsphere processing, including a waste removal box 1. The top of the waste removal box 1 is provided with a feed inlet 2, and the bottom of the waste removal box 1 is provided with a discharge port with a switch valve. A waste removal roller 4 is provided inside the waste removal box 1. One end of the waste removal roller 4 is connected to a motor 15. The output shaft of the motor 15 can be connected to the waste removal roller 4 extending out of the waste removal box through a matching sprocket, chain, pulley, or belt. The rotation of the output shaft of the motor 15 drives the waste removal roller 4 to rotate. The waste removal roller 4 is an electromagnetic roller. One end of the waste removal roller 4 is connected to an external power source through a conductive slip ring. Multiple support plates 5 are evenly distributed along the circumference of the waste removal roller 4. The multiple support plates 5 are distributed in a radial pattern along the waste removal roller 4. The support plates 5 are electromagnetic plates.

[0018] The feed inlet 2 is equipped with a movable feed hopper 3 via a movable component, and the moving direction of the feed hopper 3 is parallel to the length direction of the impurity removal roller 4.

[0019] The moving component includes a linear module 13. The outer wall of the feed hopper 3 is fixedly connected to the slide table 22 of the linear module 13. The bottom of the feed hopper 3 is connected to a discharge pipe, which extends into the feed inlet 2 and faces the impurity removal roller 4.

[0020] During operation, the material that needs to be removed enters the removal box through the feed inlet and falls onto the removal roller. The removal roller is energized to generate magnetic attraction, which attracts the metal impurities. The material with the metal impurities removed falls from the removal box and is collected. When the removal is completed, the removal roller is de-energized, the removal roller loses its magnetic attraction, and the metal impurities fall and are discharged under the action of gravity.

[0021] Example 2 like Figure 3-5 As shown, the difference between this embodiment and Embodiment 1 is that the... The impurity removal roller 4 is equipped with a scraping assembly, which includes a scraping frame 6. The scraping frame 6 is matched with the impurity removal roller 4 and the support plate 5. The scraping frame 6 is sleeved on the scraping roller. The scraping frame 6 is connected to a connecting assembly, which includes a moving ring 7 and a connecting ring 23. The outer wall of the scraping frame 6 is fixedly connected to the inner ring surface of the connecting ring 23. The outer ring surface of the connecting ring 23 is rotatably connected to the inner ring surface of the moving ring 7 through a bearing. The outer ring surface of the moving ring 7 is fixedly connected to a second moving component, which drives the connecting assembly to reciprocate along the length direction of the impurity removal roller 4.

[0022] The second moving component includes a second linear module. The top of the moving ring 7 is connected to the second slide of the second linear module via a connecting rod, and the moving ring 7 moves with the second slide.

[0023] The feed hopper moves continuously during feeding, which allows the material entering the impurity removal box to fall evenly onto the impurity removal roller, increasing the usable area of ​​the impurity removal roller and further improving the impurity removal effect and efficiency.

[0024] Example 3 like Figure 3-5 As shown, the difference between this embodiment and Embodiment 2 is that the second moving component includes a horizontal screw 10, a guide rod 11, and a second reversible motor 14. The horizontal screw 10 and the guide rod 11 are arranged parallel to each other at the feed inlet 2. One end of the horizontal screw 10 is connected to the second motor 14, which drives the horizontal screw 10 to rotate in both directions. A slider 9 is threaded onto the horizontal screw 10, and the slider 9 is connected to the outer wall of the moving ring 7 via a first fixing rod 8. A guide block 12 is slidably sleeved on the guide rod 11, and the guide block 12 is connected to the outer wall of the moving ring 7 via the second fixing rod. The second moving component drives the connecting component to reciprocate along the length of the impurity removal roller, and the scraper frame scrapes off the metal impurities adhering to the impurity removal roller without affecting the next impurity removal operation.

[0025] Example 4 like Figure 6-9 As shown, the difference between this embodiment and embodiment 3 is that a receiving assembly is provided below the impurity removal roller 4. The receiving assembly includes a receiving plate 17, which is inclined along the length of the impurity removal roller 4. The impurity removal box 1 corresponding to the lower end of the receiving plate 17 is provided with an openable and closable discharge port 18. The receiving plate 17 is connected to a rotating assembly, which includes a rotating ring 16, a rotating shaft 19, and a motor 21. The central axis of the rotating ring 16 and the rotating shaft 19 coincides with the central axis of the impurity removal roller 4. The lower end of the receiving plate 17 is fixedly connected to the rotating ring 16. 16 is rotatably connected to the inner wall of the impurity removal box 1 via bearings. The rotating shaft 19 is fixedly connected to the high end of the receiving plate 17. The vertical distance from the high end of the receiving plate 17 to the central axis of the rotating shaft 19 is greater than the radius of the moving ring 7, so that the receiving plate 17 and the impurity removal roller 4 do not interfere with each other and the receiving plate 17 does not affect the rotation of the impurity removal roller 4. The rotating shaft 19 passes through the impurity removal box 1 and is connected to the motor 21. The output shaft of the motor 21 and the rotating shaft 19 outside the impurity removal box 1 are respectively fixedly connected to sprockets. The two sprockets are connected by a matching transmission chain 20. The motor 21 drives the receiving plate 17 to rotate.

[0026] The receiving plate 17 is an arc-shaped plate, and the arc shape can reduce the falling of metal impurities.

[0027] When the material enters the impurity removal box, the receiving plate is located on one side of the impurity removal roller, which will not affect the falling of the material after impurity removal. When the impurity removal roller needs to be cleaned, the feeding is stopped, the receiving plate rotates to the bottom of the impurity removal roller, the impurity discharge port opens, the impurity removal roller is de-energized, and the metal impurities fall off the impurity removal roller onto the receiving plate and are discharged from the impurity discharge port. After the impurity removal roller is cleaned, the receiving plate rotates back to the side of the impurity removal roller, and the feeding and impurity removal can continue. In the above process, the outlet of the material after impurity removal is different from that of the metal impurities. When the material and impurities are discharged alternately, there is no need to change the receiving device of the discharge port, which reduces labor and labor costs.

[0028] In the above embodiments, motor one, motor two, motor three (preferably a geared motor), linear module one, linear module two, conductive slip ring, sprocket chain, pulley and belt, transmission chain, etc., adopt conventional equipment and means in the field, without modification, and can be used with reference to the instruction manual.

[0029] The embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
