Description

Technical Field

[0001] The utility model relates to the technical field of diamond micropowder processing, in particular to a device for grading and segmenting diamond micropowder. Background Art

[0002] Diamond micropowder is a super-hard and ultra-fine abrasive, which is widely used for grinding and polishing high-hardness materials. Diamond micropowder can be obtained into micropowders of different particle sizes after screening. Diamond micropowders of different particle sizes are used in different fields to achieve better grinding effects.

[0003] The existing diamond micropowder grading method mainly uses a sieve plate to screen and grade diamond micropowders of different particle sizes. However, during the screening process, the diamond micropowder drops vertically and is concentrated in a part of the sieve plate. The diamond micropowder falls unevenly, and other parts of the sieve plate cannot be fully utilized. The screening efficiency is low and there is also a blockage problem, which is not conducive to the simultaneous screening of large amounts of diamond micropowder. Utility Model Content

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The utility model provides Figure 1-Figure 7 The device shown for grading and segmenting diamond powder includes a base 8, a screening assembly 4 is disposed above the base 8, and the screening assembly 4 includes a plurality of enclosure shells 46, each of which is provided with an enclosure plate 43 on the top, and a sieve plate 42 is disposed inside the enclosure shell 46. A discharge channel 45 is provided on one side of the enclosure shell 46, and a discharge pipe 41 is provided at the extended end of the discharge channel 45;

[0028] A top cover 3 is provided on the top of the enclosure 43 at the top of the screening assembly 4. A feed hopper 1 is provided on the top of the top cover 3. A guide block 9 is provided inside the feed hopper 1. The guide block 9 is a conical structure. The bottom end of the guide block 9 passes through the top of the top cover 3 and extends into the top cover 3.

[0029] Specifically, during the screening process, the diamond powder is discharged downward from the top of the feed funnel 1, falls on the guide block 9, then flows along the outer wall of the guide block 9, and then moves from the outer wall of the guide block 9 in multiple directions, thereby evenly falling downward into the enclosure shell 46 at the top of the screening component 4, and falling on the screen plate 42.

[0030] like Figure 1-Figure 4 As shown, specifically, a plurality of air holes are provided on the top of the guide block 9, and a plurality of fixing rods 10 are provided on the outer wall of the guide block 9, and the extending ends of the fixing rods 10 pass through the feed funnel 1;

[0031] Specifically, the diamond powder with very small particle size can directly pass through the air holes on the top of the guide block 9 during the process of falling downward, thereby making the diamond powder falling more efficient;

[0032] like Figure 1-Figure 4 As shown, a support frame 2 is further provided between the feed funnel 1 and the top cover 3, and a plurality of protrusions 11 are provided on the inner wall of the bottom end of the feed funnel 1; specifically, the support frame 2 improves the stability between the feed funnel 1 and the top cover 3, avoids the problem of loose connection between the feed funnel 1 and the top cover 3 due to frequent shaking, and improves the reliability of the feed funnel 1 and the top cover 3.

[0033] like Figures 1-6 As shown, a slot 44 is formed at the bottom of each enclosure shell 46, and the top of the enclosure plate 43 cooperates with the slot 44. The bottom plate 15 is fixed in the enclosure shell 46 at the bottom of the screening assembly 4. Specifically, during the assembly of the screening assembly 4, the enclosure plate 43 at the top of each enclosure shell 46 is inserted into the slot 44 at the bottom of the upper enclosure shell 46, and the enclosure plate 43 is locked from the side wall of the enclosure shell 46 with bolts to ensure that the enclosure plate 43 will not fall out of the slot 44.

[0034] It should be noted that the diamond powder that falls into the bottommost enclosure housing 46 falls on the top of the bottom plate 15 and is finally discharged from the drop pipe 41 .

[0035] like Figures 1-6 As shown, a spring column 12 is provided at the bottom of the bottom plate 15, a base 8 is provided at the bottom end of the spring column 12, a protective plate 5 is provided on the outside of the spring column 12, a fixing plate 13 is further provided at the bottom of the bottom plate 15, and a vibration motor 14 is provided on the inner wall of the fixing plate 13;

[0036] Specifically, after starting the vibration motor 14, the vibration motor 14 generates vibration and drives the bottom plate 15, the bottom plate 15 drives the screening component 4, the screening component 4 drives the upper screening component 4, thereby driving the feed funnel 1 and the top cover 3 to vibrate. Under the vibration action of the vibration motor 14, the entire device can be driven to vibrate, and the diamond micropowder falling on the top of the sieve plate 42 is screened due to the vibration. The diamond micropowder smaller than the sieve hole of the sieve plate 42 falls down to the sieve plate 42 in the next enclosure shell 46, and the sieve plate 42 screens the diamond micropowder again until the sieve plate 42 in the last enclosure shell 46 completes the screening.

[0037] like Figure 1-Figure 5 As shown, a collection barrel 6 is further provided on the top of the base 8, a cover plate 63 is provided on the top of the collection barrel 6, a baffle 61 is fixed on the top of the cover plate 63, a feed port 62 is provided on the top of the cover plate 63 on one side of the baffle 61, and a nozzle 64 is provided on the other side. A filter membrane 65 is provided inside the collection barrel 6, and a drain pipe 7 is provided on one side of the bottom of the collection barrel 6, and a valve is also provided on the drain pipe 7;

[0038] Specifically, a collection barrel 6 can be placed under the drop pipe 41 on the outer wall of each enclosure shell 46, and the operation of cleaning diamond micropowder can be carried out in each collection barrel 6. After the diamond micropowder undergoes multi-stage screening, diamond micropowder of different particle sizes falls into different collection barrels 6. The nozzle 64 is connected to the pipeline of the external flushing equipment. The external flushing equipment transports the cleaning liquid through the pipeline and sprays it from the nozzle 64, thereby flushing the diamond micropowder that falls into the collection barrel 6. The diamond micropowder falls on the top of the filter membrane 65, and the water seeps through the filter membrane 65, and then accumulates at the bottom of the inner part of the collection barrel 6. After opening the valve on the drain pipe 7, the sewage can be discharged from the drain pipe 7.

[0039] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
