[0043] It can be seen that the separator body 100 is the main structure of the entire device; the feed pipe 110 enables the coal powder to enter the interior of the device accurately and efficiently. When the coal powder enters the interior of the device, the entire separation process begins; the first inner cone bucket 120 utilizes the gravity and flow characteristics of the coal powder to perform preliminary separation of the coal powder; the second inner cone bucket 140 and the first inner cone bucket 120 form a double-layer cone bucket structure, which can further improve the separation efficiency of the coal powder.

[0044] It can be seen that the adjustment component is used to flexibly adjust the entire device according to actual conditions during operation; the lifting component is used to lift and lower the first inner cone bucket 120, which not only helps to optimize the flow path of the coal powder, but also can adjust the separation effect of the device according to actual needs; the grinding component is located between the outer wall of the first inner cone bucket 120 and the inner wall of the second inner cone bucket 140, and can grind the coal powder that does not meet the separation requirements to achieve a higher separation accuracy. It can be understood that the inner cone bucket structure of the double-adjustable split-flow separator provided in this embodiment realizes efficient and accurate separation of coal powder.

[0045] Specifically, the inner cone bucket structure of the double-adjustable split-flow separator further includes: a screening assembly 180 , which is located above the first inner cone bucket 120 .

[0046] It can be seen that the screening component 180 is preferably a plurality of flow limiting channels arranged in the vertical direction.

[0048] It can be seen that the distributor 190 is located at the top of the separator body 100, and the top of the distributor 190 is provided with a coal powder outlet 200. The number of coal powder outlets 200 can be adjusted according to actual needs to meet the requirements of different working scenarios; after the coal powder has undergone preliminary screening and separation, the coal powder that meets the requirements will be discharged through the coal powder outlet 200, thereby realizing efficient and precise separation of the coal powder.

[0049] Specifically, the inner cone bucket structure of the double-adjustable diversion separator also includes: a first blade 210, which has a plurality of first blades 210 evenly arranged on the top of the first inner cone bucket 120 in the vertical direction, and one end of the first blade 210 is fixedly connected to the inner wall of the first inner cone bucket 120; a second blade 220, which has a plurality of second blades 220 located inside the distributor 190, and the second blades 220 are arranged along the circumferential direction of the feed pipe 110, and one end of the second blade 220 is connected to the feed pipe 110.

[0050] It can be seen that the first blades 210 play a guiding role when the coal powder is separated. By adjusting the angle and number of the first blades 210, the flow speed and flow path of the coal powder in the first inner cone 120 can be controlled, thereby optimizing the separation effect of the coal powder; the second blades 220 play a guiding role in the process of the coal powder entering the separator body 100. By adjusting the angle and number of the second blades 220, the speed and distribution of the coal powder entering the separator body 100 can be controlled, so that the coal powder enters the separator body 100 more evenly, further improving the separation efficiency of the coal powder.

[0051] Specifically, the adjustment component includes: a first telescopic rod 151, one end of which is connected to the outer wall of the second inner cone bucket 140, and the other end of the first telescopic rod 151 is connected to the inner wall of the separator body 100; a first drive motor 152, the output end of which is connected to one end of the first telescopic rod 151 close to the inner wall of the separator body 100.

[0052] Specifically, the second inner cone bucket 140 includes a plurality of inner cone bucket pieces 141 , and each inner cone bucket piece 141 is connected to the first telescopic rod 151 .

[0053] It can be seen that the first telescopic rod 151 is used to achieve the relative position adjustment between the second inner cone bucket 140 and the separator body 100, and the first drive motor 152 is used to drive the first telescopic rod 151 to perform telescopic movement, so as to achieve the position adjustment of the second inner cone bucket 140; the second inner cone bucket 140 is composed of a plurality of inner cone bucket pieces 141, and each inner cone bucket piece 141 is connected to the first telescopic rod 151, which makes the adjustment of the second inner cone bucket 140 more flexible, and each inner cone bucket piece 141 can be individually adjusted according to actual needs to further optimize the separation effect of coal powder.

[0054] Specifically, the lifting assembly includes: a second telescopic rod 161, one end of which is connected to the inner top wall of the separator body 100, and the other end of the second telescopic rod 161 is connected to the top of the first inner cone bucket 120; a second drive motor 162, the output end of which is connected to one end of the second telescopic rod 161 close to the inner top wall of the separator body 100.

[0055] It can be seen that the second telescopic rod 161 is used to realize the lifting movement of the first inner cone bucket 120, and the second drive motor 162 is used to drive the second telescopic rod 161 to perform telescopic movement, thereby realizing the height adjustment of the first inner cone bucket 120; this can adjust the position of the first inner cone bucket 120 according to actual needs, and optimize the flow path and separation effect of the coal powder.

[0056] Specifically, the grinding assembly includes: a grinding body 171, which has a plurality of grinding bodies 171, and the plurality of grinding bodies 171 are evenly arranged on the outer wall of the first inner cone bucket 120 and the inner wall of the second inner cone bucket 140; wherein the grinding body 171 is a hemispherical grinding body 171.

[0057] It can be seen that the grinding body 171 is hemispherical, which can effectively grind the coal powder and improve the separation accuracy of the coal powder; the grinding body 171 is evenly arranged on the outer wall of the first inner cone bucket 120 and the inner wall of the second inner cone bucket 140, which enables the coal powder to be evenly ground during the flow process, further improving the separation efficiency of the coal powder.

[0058] Specifically, the cone angle of the first inner cone bucket 120 is the same as the cone angle of the second inner cone bucket 140 , the outer radius of the first inner cone bucket 120 is smaller than the inner radius of the second inner cone bucket 140 , and the difference between the outer radius of the first inner cone bucket 120 and the inner radius of the second inner cone bucket 140 is the diameter of the grinding body 171 .

[0059] It can be seen that the cone angles of the first inner cone bucket 120 and the second inner cone bucket 140 are the same, which ensures the consistency of the flow characteristics of the coal powder in the double-layer cone bucket structure, thereby improving the separation efficiency of the coal powder; at the same time, the outer radius of the first inner cone bucket 120 is smaller than the inner radius of the second inner cone bucket 140, and the difference between the two is exactly equal to the diameter of the grinding body 171. This design enables the grinding body 171 to fit tightly between the first inner cone bucket 120 and the second inner cone bucket 140, thereby grinding the coal powder more effectively and further improving the separation accuracy and separation efficiency of the coal powder.

[0060] It should also be noted that the second inner cone bucket 140 is telescopically moved by the adjusting component, and the first inner cone bucket 120 is lifted and lowered by the lifting component. Grinding bodies 171 are provided on the outer wall of the first inner cone bucket 120 and the inner wall of the second inner cone bucket 140. When the coal powder enters the first inner cone bucket 120 from the coal powder inlet 130, the position and angle of the first inner cone bucket 120 and the second inner cone bucket 140 can be accurately adjusted through the coordinated action of the adjusting component and the lifting component, thereby optimizing the flow path and separation effect of the coal powder. When the coal powder that does not meet the separation standards falls, a part of it falls directly to the bottom of the separator body 100 to continue to be ground, and the other part is ground and screened multiple times between the first inner cone bucket 120 and the second inner cone bucket 140 through the action of the grinding body 171, which further improves the separation efficiency of the coal powder and ensures the quality and purity of the coal powder.

[0061] In summary, the inner cone bucket structure of the double-adjustable diversion separator provided in this embodiment realizes efficient and accurate separation of coal powder through the synergistic effect of the double-layer cone bucket structure, the adjustment component, the lifting component, the grinding component and the screening component 180; the device also has the advantages of simple structure, flexible adjustment, high separation efficiency, etc., and can be widely used in the coal powder separation process in the coal, chemical, electric power and other industries.
