Description

Technical Field

[0001] This utility model belongs to the field of alloy powder filtration technology, and in particular relates to a sieve filtration device for the production of hard alloy powder. Background Technology

[0002] During the production of cemented carbide powder, the resulting powders vary in size. They need to be sieved during subsequent processing or use. This requires a sieving device for cemented carbide powder production, which can effectively sieve the cemented carbide powder.

[0003] The current screening devices for cemented carbide powder production have the following problems in actual use: In actual use, the traditional screening devices for cemented carbide powder production directly pour the alloy powder into the screening chamber. Since the top of the device does not have a shielding device, the alloy powder inside the screening chamber may jump out of the device when the device vibrates during screening. Furthermore, after screening is completed, the device needs to be inverted to pour out the unscreened alloy powder, which is very troublesome to use. Utility Model Content

By installing the spring 3 and the vibration motor 6, the hopper 5 can be provided with a vibration effect. Under the effect of the filter screen 17, the alloy powder can be screened, which is very convenient to use.

[0026] A first external threaded rod 10 is welded to the top of the support ring 8. The first external threaded rod 10 passes through the filter ring 9. A first nut 11 is sleeved on the surface of the first external threaded rod 10. One end of the first nut 11 is attached to the top of the filter ring 9. By installing the first external threaded rod 10, when installing the filter ring 9, the first external threaded rod 10 can pass through the filter ring 9. At this time, the first nut 11 can be sleeved on the surface of the first external threaded rod 10 until one end of the first nut 11 is attached to the top of the filter ring 9. This can provide stability for the filter ring 9 during use.

[0027] A groove 14 is formed on the surface of the retaining ring 13, and a second external threaded rod 15 is welded to the surface of the retaining ring 12. The second external threaded rod 15 is located inside the groove 14, and a second nut 16 is sleeved on the surface of the second external threaded rod 15. One end of the second nut 16 is attached to the surface of the retaining ring 13. By forming the groove 14, when installing the retaining ring 13, the second external threaded rod 15 can be placed inside the groove 14 until the bottom of the retaining ring 13 is attached to the top of the filter ring 9. At this time, the second nut 16 can be sleeved on the surface of the second external threaded rod 15 until one end of the second nut 16 is attached to the surface of the retaining ring 13, thereby providing a fixed installation effect for the retaining ring 13 and ensuring the stability of the retaining ring 13 during use.

[0028] The top of the cover plate 18 is fixedly connected to the fixing block 22, which is symmetrically distributed. The handle 23 is sleeved inside the fixing block 22. Both ends of the handle 23 are welded with baffles 24. By installing the handle 23, when it is necessary to move the cover plate 18, the retaining ring 13 and the filter ring 9, the handle 23 can be used directly as the force point. The handle 23 can directly move the cover plate 18, the retaining ring 13 and the filter ring 9, which is very convenient to use.

[0029] The grooves 14 are arranged in a ring shape, and the second external thread rod 15 is arranged in a ring shape. The arrangement of the second external thread rod 15 can further improve the stability of the retaining ring 13 after installation, resulting in stronger stability during use.

[0030] The working principle of the sieving device for cemented carbide powder production is as follows: When using this device, the retaining ring 13 should be installed first. At this time, the second external threaded rod 15 can be placed inside the groove 14 until the bottom of the retaining ring 13 is attached to the top of the filter ring 9. Then, the second nut 16 can be sleeved on the surface of the second external threaded rod 15 until one end of the second nut 16 is attached to the surface of the retaining ring 13, thereby providing a fixed installation effect for the retaining ring 13. After that, the filter ring 9 is installed. When installing the filter ring 9, the first external threaded rod 10 can pass through the filter ring 9. Then, the first external threaded rod 10 is used to install the filter ring 9. The first nut 11 is fitted onto the surface of the filter ring 9 until one end of the first nut 11 is attached to the top of the filter ring 9. Then, the cover plate 18 is installed. When installing the cover plate 18, the external threaded ring 20 can be directly installed inside the retaining ring 13 by rotation. The device can then be used. When using the device, a support ring 8 is welded inside the chamber 5, and the filter ring 9 is installed on top of the support ring 8. A filter screen 17 is welded inside the filter ring 9. A retaining ring 12 is fixedly connected to the top of the filter ring 9, and a retaining ring 13 is fitted onto the surface of the retaining ring 12. An internal thread is formed inside the retaining ring 13. A limiting ring 21 is welded inside the retaining ring 13, and an external threaded ring 20 is fitted inside the retaining ring 13. At this time, the bottom of the external threaded ring 20 is in contact with the limiting ring 21. A cover plate 18 is welded inside the external threaded ring 20, and a funnel-shaped feed inlet 19 is opened inside the cover plate 18. When using the device, alloy powder can be directly poured into the inside of the retaining ring 13 from the funnel-shaped feed inlet 19. At this time, the alloy powder is located between the cover plate 18, the retaining ring 13, and the filter screen 17. Then, the vibration motor 6 is turned on. Under the action of the vibration motor 6 and the spring 3, the chamber 5 can be vibrated. Based on the filter screen 17, the alloy powder inside the chamber 5 can be sieved. When the device vibrates, the alloy powder will not jump out of the device due to the vibration. When removing the alloy powder that has not passed the sieve, the filter ring 9 can be removed directly. At this time, the cover plate 18, the retaining ring 13 and the filter screen 17 can provide a bearing place for the alloy powder. Then, the handle 23 can be used as the force point to drive the cover plate 18, the retaining ring 13 and the filter screen 17 to clean out the alloy powder. It is very convenient to use.
