Description

Technical Field

[0001] This utility model relates to the field of vibration sorting technology, specifically to a multi-stage vibration sorting device for powder metallurgy particles. Background Technology

[0002] Powder metallurgy is a process technology that involves producing metal powders or using metal powders as raw materials, followed by forming and sintering to manufacture metallic materials, composite materials, and various types of products. Powder metallurgy shares similarities with ceramic production, both belonging to powder sintering technology; therefore, a series of new powder metallurgy technologies can also be applied to the preparation of ceramic materials. Due to its advantages, powder metallurgy technology has become a key to solving new material problems and plays a crucial role in the development of new materials. Powder metallurgy particles refer to the tiny solid particles used in powder metallurgy processes. These particles are the basic building blocks of powder metallurgy materials, and they need to be sorted during use.

[0003] A search revealed problems with existing powder metallurgy particle sorting technologies. During sieving, powder metallurgy particles collide and rub against screens, equipment components, or other powder particles, generating static electricity. This static electricity charges the particles, causing them to attract each other and form clumps, leading to powder agglomeration. Static-charged particles easily adhere to the screen surface, especially when the screen aperture is similar to the powder particle size, making it easier for particles to wedge into the screen holes, causing screen blockage. Frequent adhesion and blockage not only reduce sieving efficiency but also hinders the improvement of sorting efficiency. Therefore, based on the above research and existing technologies, a multi-stage vibration sorting device for powder metallurgy particles is proposed to solve these problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In one typical embodiment of this application, please refer to Figures 1-5A multi-stage vibration sorting device for powder metallurgy particles includes a base 1, a support frame 2 on the top surface of the base 1, a screen 24 fixedly installed inside the support frame 2, a mesh plate 25 fixedly installed on one side of the screen 24, the screen 24 and the mesh plate 25 having the same aperture, a screen 26 fixedly installed on one side of the mesh plate 25, a mesh plate 27 fixedly installed on one side of the screen 26, the screen 26 and the mesh plate 27 having the same aperture, a screen 3 28 fixedly installed on one side of the mesh plate 27, and one side of the screen 3 28 fixedly connected to one side of the inside of the support frame 2. The aperture of the screens gradually decreases from the screen 24 to the screen 26 and then to the screen 3 28. A feed hopper 3 for feeding is fixedly installed on one side of the support frame 2.

[0023] In this process, powder metallurgy particles are poured into the inside of the feed hopper 3 and discharged along screen 1 24, screen 26 and screen 3 28, achieving graded screening. The anti-agglomeration mechanism 6 is set on the top surface of the support frame 2 to prevent powder metallurgy particles from agglomerating.

[0024] The anti-clogging mechanism 6 includes a support cover 5, which is bolted to the top surface of the support frame 2. Two air intake fans 12 are rotatably connected to one side of the support cover 5. Several high-voltage power generators 10 are fixedly installed on the top surface of the support cover 5. Ion needles 11 are connected to the bottom surface of the high-voltage power generators 10 through wires.

[0025] In this process, by connecting the high-voltage power generator 10 to the ion needle 11, the ion needle 11 generates positive and negative ions. The two air intake fans 12 rotate to generate airflow, which blows the positive and negative particles to the powder metallurgy particles. The positive and negative ions neutralize the static charge on the surface of the material, eliminate static electricity, and prevent adhesion and agglomeration.

[0026] A support box 13 is fixedly installed on one side of the support cover 5. A support tube 15 is fixedly installed on the bottom surface of the support box 13. A cover plate 16 is rotatably connected to the bottom surface of the support tube 15 via a hinge. A screw is connected through the bottom surface of the cover plate 16. A threaded groove is opened on the bottom surface of the support tube 15. One end of the screw is threadedly connected to the threaded groove. The cover plate 16 can be fixed to the bottom surface of the support tube 15 by the screw.

[0027] An exhaust fan 21 for exhaust is rotatably connected to one side of the support box 13. Two support blocks 18 are fixedly installed on the top and bottom surfaces inside the support box 13. A composite filter 17 is slidably connected inside the support box 13. Several mounting rods 19 are fixedly installed on one side of the composite filter 17. The mounting rods 19 are elastically connected to the support blocks 18 through springs 20. Springs 20 are sleeved on the outer circular wall of the mounting rods 19. One end of springs 20 is fixedly connected to one side of the support block 18, and the other end of springs 20 is fixedly connected to one end of the mounting rods 19. Springs 20 can provide elastic force to the composite filter 17.

[0028] A cam 22 is rotatably connected to the inner top surface of the support box 13. A drive motor 23 for driving the cam 22 to rotate is installed on the top surface of the support box 13. One end of the drive shaft of the drive motor 23 passes through the support box 13 and is fixedly connected to the top surface of the cam 22.

[0029] In the process of using airflow carrying positive and negative ions to prevent powder metallurgy particles from clumping and adhering, some powder metallurgy particles will escape. The escaped powder metallurgy particles are blocked by the composite filter screen 17. The cam 22 is driven to rotate by the drive motor 23. The rotation of the cam 22 causes the composite filter screen 17 to shake under the cooperation of the mounting rod 19 and the spring 20. The shaking causes the powder metallurgy particles to enter the interior of the support tube 15, which facilitates the long-term use of the composite filter screen 17.

[0030] A PLC controller is fixedly installed on one side of the base 1. The high-voltage power generator 10, the intake fan 12, the exhaust fan 21 and the drive motor 23 are electrically connected to the PLC controller.

[0031] Preferably, through the feeding hopper 3, the worker pours the powder metallurgy particles into the inside of the feeding hopper 3. The powder metallurgy particles enter the inside of the support frame 2 through the feeding hopper 3. The powder metallurgy particles first pass through screen 1 24 and screen plate 1 25. The largest powder metallurgy particles are discharged through screen 1 24, while screen plate 1 25 can block the largest powder metallurgy particles. Other powder metallurgy particles continue forward. Medium-sized powder metallurgy particles enter screen 26 and screen plate 27. Medium-sized powder metallurgy particles are discharged through screen 26, while screen plate 27 can block medium-sized powder metallurgy particles. The remaining powder metallurgy particles enter screen 3 28, and the smallest powder metallurgy particles are discharged through screen 3 28, thereby classifying and screening the powder metallurgy particles.

[0032] During this process, some powder metallurgy particles may agglomerate or adhere to screens 24, 26, and 28 due to static electricity. The PLC controller starts the high-voltage power generator 10, which is connected to the ion needle 11 to generate positive and negative ions. The air intake fan 12 rotates, causing the airflow to carry the positive and negative ions along the inside of the support frame 2. The airflow blows the positive and negative particles onto the powder metallurgy particles. The positive and negative ions neutralize the static charge on the surface of the powder metallurgy particles, eliminating the static electricity on them and preventing the powder metallurgy particles from agglomerating and adhering due to static electricity.

[0033] At the same time, the airflow carrying positive and negative ions may cause some powder metallurgy particles to escape. The escaped powder metallurgy particles will be blocked by the support cover 5. The PLC controller starts the exhaust fan 21. The start of the exhaust fan 21 causes the airflow carrying powder metallurgy particles inside the support frame 2 and the support cover 5 to pass through the composite filter 17. The composite filter 17 will block the powder metallurgy particles and prevent them from entering the air.

[0034] During prolonged use, the composite filter 17 may become clogged. The PLC controller starts the drive motor 23, and the drive shaft of the drive motor 23 rotates, causing the cam 22 to rotate. When the tip of the cam 22 rotates to contact the composite filter 17, the composite filter 17 causes the mounting rod 19 to move outward on the support block 18, while simultaneously compressing the spring 20. When the round end of the cam 22 rotates to contact the composite filter 17, the force of the spring 20 causes the mounting rod 19 to move the composite filter 17 inward. The rotation of the cam 22 and the spring 20 work together to make the composite filter 17 sway back and forth. This causes the powder metallurgy particles that are clogged on the composite filter 17 to fall into the interior of the support tube 15, preventing them from becoming clogged. This allows the composite filter 17 to continue filtering the scattered powder metallurgy particles, achieving an anti-agglomeration effect on the powder metallurgy particles and aiding in the grading and sorting of the powder metallurgy particles.

[0035] Several connecting pipes 29 are fixedly installed on the top surface of the base 1, and several connecting columns 30 are fixedly installed on the bottom surface of the support frame 2. The outer circular wall of the connecting column 30 is slidably connected to the inner circular wall of the connecting pipe 29. A second spring 31 is sleeved on the outer circular wall of the connecting pipe 29. One end of the second spring 31 is fixedly connected to the top surface of the base 1, and the other end of the second spring 31 is fixedly connected to the bottom surface of the support frame 2. Vibration motors 4 are installed at an angle on both sides of the support frame 2. The vibration motors 4 are electrically connected to the PLC controller.

[0036] The vibration motor 4 drives the support frame 2 to vibrate. The vibration of the support frame 2 causes the connecting column 30 to move inside the connecting pipe 29, while the spring 31 is compressed and rebounds, thus achieving vibration screening of powder metallurgy particles.

[0037] Preferably, the vibration motor 4 is provided, and the vibration of the vibration motor 4 drives the support frame 2 to vibrate. The vibration of the support frame 2 causes the connecting column 30 to move inside the connecting tube 29, while the second spring 31 is continuously compressed and rebounded, thereby increasing the vibration of the support frame 2 and the first screen 24, the second screen 26 and the third screen 28, which facilitates the vibration sorting of powder metallurgy particles.

[0038] The base 1 has several collection boxes 9 inside for collecting powder metallurgy particles. The collection boxes 9 correspond to sieve 1 24, sieve 2 26 and sieve 3 28 respectively. The collection boxes 9 collect powder metallurgy particles of different sizes respectively.

[0039] Preferably, multiple collection boxes 9 are located on the bottom surfaces of screen 1 24, screen 2 26 and screen 3 28 respectively, through the collection boxes 9, so as to collect powder metallurgy particles of different sizes.

[0040] Several threaded posts 14 are connected through one side of the base 1. One end of the threaded post 14 passes through the base 1 and is threadedly connected to one side of the collection box 9. A threaded groove is opened on one side of the collection box 9. One end of the threaded post 14 is threadedly connected to the inner circular wall of the threaded groove. The collection box 9 can be fixed by the threaded post 14.

[0041] Preferably, by setting up the collection box 9, the worker places the collection box 9 on the base 1, places the threaded post 14 on one side of the base 1 and rotates the threaded post 14 so that one end of the threaded post 14 enters the threaded groove on the side of the collection box 9, thereby fixing the position of the collection box 9.

[0042] Two fixing blocks 7 are fixedly installed on both sides of the base 1. The top surface of the fixing block 7 is provided with fixing holes 8. The base 1 can be fixed by fitting the bolts into the fixing holes 8.

[0043] Preferably, by using the fixed block 7, the worker inserts the bolt into the fixed hole 8 on the fixed block 7, thereby fixing the base 1 to the ground as needed.

[0044] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
