Description

Technical Field

[0001] This utility model relates to the field of modified plastics production technology, specifically to a device for removing metal impurities in the production of modified plastics. Background Technology

[0002] Equipment for removing metal impurities in modified plastics production is a specialized device designed to separate metal impurities mixed in raw materials or melts. It removes impurities through magnetic separation combined with a separation mechanism to ensure the purity of modified plastic products, avoid equipment wear, and improve product performance stability.

[0003] Utility model patent CN219946894U discloses a strong magnetic iron removal vibrating screen for modified plastic production, including a screening box and a vibrating screen. The screening box contains a screening chamber and a fixed frame. A cylindrical tube is located at the bottom of the fixed frame, and a discharge plate is located at the bottom of the cylindrical tube. A pad is fixedly installed inside the cylindrical tube. A rotating rod is rotatably mounted at the center of the pad. A movable block and a sleeve are fitted around the rotating rod. A transmission rod is located at the bottom of the movable block, and a ball head is located at the bottom of the transmission rod that contacts the pad. The elastic element is connected to the inner wall of the screening box. This strong magnetic iron removal vibrating screen for modified plastic production can filter materials and adsorb metal impurities. The rotating tube drives the scraper to rotate, preventing material from clogging the screen. The strong magnet adsorbs metal impurities, improving the iron removal efficiency of the modified plastic.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: While existing metal impurity removal equipment can effectively prevent material from clogging the screen and improve the iron removal efficiency of modified plastics, in practical applications, it cannot collect metal impurities adsorbed by strong magnetic blocks. When a large amount of metal impurities are adsorbed, they tend to accumulate on the surface of the strong magnetic blocks, which not only weakens the magnetic adsorption capacity, making it difficult to effectively capture subsequent metal impurities and causing missed detection, but also requires manual cleaning after shutdown, prolonging the equipment's idle time. Furthermore, if impurities fall off during the cleaning process, they may re-mix with the material, causing secondary pollution and affecting the removal efficiency of the metal impurity removal equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0018] I. This utility model, by setting up components such as a feeding filter assembly and a cleaning collection assembly, uses an electric push rod to drive a moving rod, which in turn drives a pushing ring to move the feeding plate to control the feeding. The electromagnetic block on the filter plate adsorbs metal impurities. When the collection box moves with the moving rod, the pushing block, in conjunction with an inclined plate that rotates via a torsion spring and is magnetically connected to the electromagnetic block, adsorbs and collects the metal impurities. Thus, this device can collect the screened metal impurities, avoiding the accumulation of impurities that weakens magnetic adsorption, and eliminating the need for manual cleaning by stopping the machine.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] See attached document Figure 1-4 A device for removing metal impurities in the production of modified plastics includes: a device body 1, a feed pipe 2 and a discharge port 3. The top of the device body 1 is connected to the feed pipe 2, and the discharge port 3 is opened on one side of the device body 1. A feeding filter assembly 4 is fixedly connected to the top surface inside the device body 1. The feeding filter assembly 4 includes an electric push rod 41. A moving rod 42 is fixedly connected to the output end of the electric push rod 41. A pushing ring 43 is fixedly connected to the surface of the moving rod 42. A feeding plate 44 is fixedly connected to the surface of the pushing ring 43. A filter plate 45 is provided at the bottom of the feeding plate 44 and is fixedly connected to the inside of the device body 1. Several sets of electromagnetic blocks 46 are fixedly connected inside the filter plate 45.

[0030] The device body 1 is equipped with a cleaning and collection component 5, which includes a collection box 51. The top of the collection box 51 is fixedly connected to the bottom of the moving rod 42. Push blocks 52 are provided on both sides of the top of the collection box 51. The bottom of the filter plate 45 is rotatably connected to an inclined plate 53 through a torsion spring. The inclined plate 53 is magnetically connected to an electromagnetic block 46. A strong magnetic block 54 is provided inside the collection box 51. The electric push rod 41 drives the moving rod 42 to move. The push ring 43 drives the feeding plate 44 to move to control the feeding. The electromagnetic block 46 on the filter plate 45 can adsorb metal impurities in the material. The collection box 51 moves with the moving rod 42. The push block 52 cooperates with the inclined plate 53. The inclined plate 53 rotates through a torsion spring and is magnetically connected to the electromagnetic block 46. The strong magnetic block 54 adsorbs and collects the collected metal impurities, preventing the metal impurities from not falling down after the electromagnetic block 46 is closed. This achieves the adsorption and collection of metal impurities and reduces the accumulation of impurities.

[0031] A collecting plate 6 is detachably connected to the bottom of the strong magnetic block 54. The collecting plate 6 is slidably connected to the inside of the collecting box 51. A sealing plate 7 is provided on the outside of the collecting plate 6. The sealing plate 7 is rotatably connected to the outside of the device body 1 through a torsion spring. The collecting plate 6 at the bottom of the strong magnetic block 54 can slide to collect impurities. The sealing plate 7 on the outside of the collecting plate 6 fits against the device body 1, which facilitates the removal of impurities for cleaning and ensures the sealing of the inside of the device. A spring 8 is fixedly connected to the bottom of the pushing block 52. The spring 8 is embedded and fixedly connected to the top of the collecting box 51. A time relay 9 is fixedly connected to one side of the device body 1. The time relay 9 is connected to an electromagnetic relay via a wire. Block 46 is electrically connected. The spring 8 at the bottom of the push block 52 can buffer the force when the push block 52 contacts the inclined plate 53. The time relay 9 controls the on and off of the electromagnetic block 46 to realize the timed adsorption and release of metal impurities for easy collection. The bottom of the inclined plate 53 is fixedly connected to the magnetic shielding block 10, and the top of the push block 52 is fixedly connected to the elastic block 11. The magnetic shielding block 10 at the bottom of the inclined plate 53 can reduce the magnetic force of the strong magnetic block 54 on the inclined plate 53, ensuring that the position of the inclined plate 53 is fixed normally. The elastic block 11 at the top of the push block 52 can reduce the wear when the push block 52 contacts the inclined plate 53, and extend the service life of the components.

[0032] Several sets of electromagnetic strips 12 are fixedly connected inside the filter plate 45. The electromagnetic strips 12 are electrically connected to the time relay 9 via wires. The electromagnetic strips 12 inside the filter plate 45 enhance the adsorption range and adsorption capacity for metal impurities, further improving the removal effect of metal impurities and ensuring more thorough impurity removal. At the same time, the time relay 9 can close the electromagnetic block 46 and electromagnetic strips 12 after the electric push rod 41 moves upward for a certain period of time, causing the metal impurities to fall into the collection plate 6 and be collected. A limit plate 13 is provided on the top of the feeding plate 44. The limit plate 13 is fixedly connected inside the equipment body 1. The limit plate 13 on the top of the feeding plate 44 can limit the upward range of the feeding plate 44, avoiding... In the event of excessive movement of the feed plate 44, a concentrating plate 14 is fixedly connected to the outer side of the moving rod 42. A feed pipe 15 is provided at the bottom of the concentrating plate 14 and is connected to the discharge port 3. The concentrating plate 14 on the outer side of the moving rod 42 can collect the filtered material and then transport it to the discharge port 3 through the feed pipe 15 at the bottom, which enhances the material discharge efficiency and avoids material residue. An inclined block 16 is fixedly connected to the bottom of the limiting plate 13. The bottom of the inclined block 16 is inserted into the top of the feed plate 44. The inclined block 16 can be stably inserted into the bottom of the limiting plate 13 during use, which facilitates the control and adjustment of the material feed and enhances the stability of the feed adjustment during use.

[0033] Working principle: When using this equipment to remove metal impurities in the production of modified plastics, the modified plastic raw material to be processed must first be fed into the equipment body 1 through the feed pipe 2. At this time, the equipment is started, the electric push rod 41 starts to work and pushes the moving rod 42 to move in the vertical direction. The push ring 43 on the surface of the moving rod 42 will move synchronously. Since the push ring 43 is movably connected to the feeding plate 44, when the feeding plate 44 is subjected to the force of the push ring 43, it will move downward to create a gap at the edge, and the raw material can fall smoothly onto the filter plate 45 below.

[0034] After the raw material falls onto the filter plate 45, the electromagnetic block 46 and electromagnetic strip 12 inside the filter plate 45 will adsorb the metal impurities in the raw material. The electromagnetic strip 12 adsorbs the metal impurities during the falling process of the material and impurities, while the electromagnetic block 46 collects the metal impurities when the material falls onto the inclined plate 53 and slides, ensuring that the metal impurities in the raw material are fully adsorbed on the surface of the filter plate 45 to avoid missed detection. At the same time, the modified plastic raw material after filtration and impurity removal will fall from the mesh of the filter plate 45 onto the concentrating plate 14 outside the moving rod 42. The concentrating plate 14 gathers the raw material to the bottom feed pipe 15 through its own tilt angle. Finally, the raw material is transported to the discharge port 3 through the feed pipe 15 and discharged from the equipment body 1.

[0035] When it is necessary to remove the collected metal impurities, the electric push rod 41 and the time relay 9 can be activated. The output end of the electric push rod 41 drives the moving rod 42 upward, which in turn moves the feeding plate 44. The upward movement of the feeding plate 44 pushes the inclined block 16 to fit against the limiting plate 13, preventing the material from falling further. Subsequently, the moving rod 42 also drives the collecting box 51 to move upward. The upward movement of the collecting box 51 can press the pushing block 52 against the bottom of the inclined plate 53. When the time relay 9 reaches the preset time, it also means that... Once the material inside the filter plate 45 has been filtered, it will control the electromagnetic block 46 and electromagnetic strip 12 to be de-energized via wires. At this time, the electromagnetic force disappears, and the metal impurities that were originally adsorbed lose their adsorption force and are ready to fall off the surface of the filter plate 45. At the same time, since the inclined plate 53 is rotatably connected to the filter plate 45 through a torsion spring and was originally magnetically connected to the electromagnetic block 46, the magnetism disappears after the electromagnetic block 46 is de-energized. When the elastic block 11 at the top of the pushing block 52 contacts the inclined plate 53, it will push the inclined plate 53 to overcome the elastic force of the torsion spring and rotate, so that the metal impurities at the top of the inclined plate 53 can slide off.

[0036] During the sliding process of metal impurities, they fall into the collection plate 6. The strong magnetic block 54 immediately attracts these impurities, preventing them from shaking or falling randomly in the collection box 51, ensuring that the impurities are stably captured. Then, the electric push rod 41 is activated, causing the output end of the electric push rod 41 to push the moving rod 42 to move. The moving rod 42 pushes the feeding plate 44 to reset through the pushing ring 43, and pushes the collection box 51 to reset and move. The electromagnetic block 46 and electromagnetic strip 12 are activated, so that the electromagnetic block 46 generates a magnetic attraction to the inclined plate 53, causing the inclined plate 53 to reset and move. When it is necessary to clean the collected metal impurities, simply open the sealing plate 7 and pull out the collection plate 6. The attraction force of the strong magnetic block 54 will remove the impurities along with the collection plate 6. There is no need to stop the machine and disassemble the equipment, which shortens the cleaning time and avoids the risk of impurities being mixed into the material again.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
