Description

Technical Field

[0001] This invention relates to the field of fine powder classification technology, and in particular to a fine powder classification device and process. Background Technology

[0002] A fine powder classification device is a device used to separate and classify fine powder materials according to particle size or other characteristics.

[0003] The existing air classifier works by bringing all the material to be screened into the grading zone of the dynamic air classifier, and separating the coarse and fine materials by adjusting the speed of the stationary blades and the rotating part. This increases the load and cyclic load of the dynamic air classifier, which in turn increases the installed power of the air classifier, resulting in increased power consumption and higher operating costs.

[0004] The existing patent (publication number: CN221046641U) relates to an integrated powder classifier for coarse powder separation and fine powder classification, belonging to the technical field of powder screening equipment. It includes a coarse powder separation section and a fine powder classification section, with the coarse powder separation section located below the fine powder classification section. The coarse powder separation section has no power source and is equipped with an adjustable guide plate inside. The fine powder classification section has a rotating part inside, with stationary blades on its periphery. By adjusting the angle of the stationary blades and the rotation speed of the rotating part, medium and coarse powders of the material can be separated. This invention prioritizes the screening out of unqualified coarse powder in the coarse powder separation section, preventing it from entering the fine powder classification section, effectively reducing the load and circulating load of the fine powder classification section. The coarse powder separation section itself has no power source, effectively reducing overall power consumption. The fine powder classification section achieves particle size adjustment by adjusting the angle of the stationary blades and the rotation speed of the rotating part, with an adjustable particle size range, high powder classification efficiency, and low resistance loss and energy consumption.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, these solutions have certain limitations in practice. The performance of existing fine powder classification devices is greatly affected by material characteristics such as humidity. When the material has high humidity or high viscosity, the particles are prone to agglomeration, resulting in a poor classification effect.

[0006] Therefore, a fine powder classification device and process method are proposed. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-7 The present invention provides the following technical solution:

[0035] A fine powder grading device and process method includes a device body 1, a feed pipe 2 fixedly connected to the bottom of the device body 1, a drying rack 3 provided at the top of the feed pipe 2, and an auxiliary mechanism 4 and a dispersing mechanism 5 provided inside the drying rack 3.

[0036] The dispersing mechanism 5 includes a cone block 501, a crushing frame 502, a crushing trough 503, a support frame 504, and a sealing sleeve 505. The bottom of the cone block 501 is fixedly connected to the top of the crushing frame 502. The bottom of the crushing frame 502 extends into the interior of the crushing trough 503 and contacts the interior of the crushing trough 503. The crushing trough 503 is opened on the top of the support frame 504. The bottom of the support frame 504 contacts the bottom of the interior of the drying rack 3. The interior of the sealing sleeve 505 is fixedly connected to the surface of the support frame 504. The surface of the sealing sleeve 505 is in close contact with the bottom of the interior of the drying rack 3.

[0037] In this embodiment: by fixing the bottom of the drying rack 3 to the top of the feed pipe 2, the drying rack 3 can be conveniently used to assist in drying the material. By fixing the bottom of the cone block 501 to the top of the crushing rack 502, the material can be easily moved through the cone block 501 into the crushing trough 503. The cone block 501 drives the crushing rack 502 to break up the clumps of material inside the crushing trough 503, thereby improving the efficiency of material grading of the device body 1.

[0038] Specifically, such as Figure 3As shown, the auxiliary mechanism 4 includes a fixing ring 401 inside the drying rack 3, and four hot air blowers 403 are provided at the bottom of the fixing ring 401.

[0039] Specifically, such as Figure 3 As shown, four support rods 405 are fixedly connected to the bottom of the fixing ring 401, and the bottom of the support rods 405 is fixedly connected to the top of the cone block 501.

[0041] In this embodiment: by fixing the top of the hot air blower 403 to the bottom of the fixing ring 401, the hot air blower 403 can be conveniently used to dry the material. The side of the mounting column 404 near the support frame 504 is fixedly connected to the support frame 504, so that the mounting column 404 can be fixed to the auxiliary dispersing frame 402 through the support frame 504, thereby achieving the effect of facilitating the auxiliary dispersing frame 402 to disperse the material.

[0042] Specifically, such as Figure 4 As shown, a protective frame 10 is threadedly connected to the surface of the hot air blower 403, and a filter frame 9 is fixedly connected inside the protective frame 10.

[0043] Specifically, such as Figure 5 , Figure 5 As shown, the drying rack 3 has four screws 12 internally threadedly connected to it. The surface of the screws 12 extends into the interior of the support frame 504 and is threadedly connected to the interior of the support frame 504.

[0044] In this embodiment: by making the interior of the protective frame 10 threadedly connected to the surface of the hot air blower 403, the protective frame 10 can easily protect the interior of the hot air blower 403 through the filter frame 9, and the surface of the screw 12 can be threadedly connected to the interior of the support frame 504, thereby making it easy for the screw 12 to fix the support frame 504, thus achieving the effect of fixing the support frame 504.

[0045] Specifically, such as Figure 7 As shown, a connecting post 11 is fixedly connected to the top of the cone block 501.

[0046] Specifically, such as Figure 2 As shown, a motor 8 is fixedly connected to the top of the adjusting column 6, and a fixing frame 7 is fixedly connected to the bottom of the motor 8. The bottom of the fixing frame 7 is fixedly connected to the top of the drying rack 3.

[0047] In this embodiment: by making the surface of the adjusting block 13 contact the inside of the adjusting groove 14, the adjusting sleeve 15 can be adjusted and moved inside the adjusting groove 14 through the adjusting block 13, so that the bottom of the fixing frame 7 is fixedly connected to the top of the drying rack 3, thereby making it convenient for the fixing frame 7 to fix and support the motor 8, achieving the effect of fixing and supporting the motor 8.

[0048] A process method for a fine powder classification device, characterized in that:

[0049] S1. When grading materials, the materials are moved into the interior of the drying rack 3, and the drying rack 3 dries the materials through the hot air blower 403;

[0050] S2. When the material comes into contact with the auxiliary dispersing frame 402, the auxiliary dispersing frame 402 performs initial dispersing of the material;

[0051] S3. Make the output shaft of motor 8 drive the adjusting sleeve 15 to rotate through the adjusting column 6, and make the adjusting sleeve 15 drive the connecting column 11 to rotate through the adjusting block 13 and the adjusting groove 14, and make the connecting column 11 drive the cone block 501 to rotate.

[0052] S4. The material is moved through the cone block 501 into the crushing trough 503, and the cone block 501 drives the crushing frame 502 to break up the clumped material inside the crushing trough 503, thereby improving the efficiency of material classification of the device body 1.

[0053] Working principle: When classifying materials, the materials are moved into the drying rack 3, where the drying rack 3 dries the materials using a hot air blower 403. Simultaneously, when the materials come into contact with the auxiliary dispersing rack 402, the auxiliary dispersing rack 402 initially disperses the materials. Then, the output shaft of the motor 8 drives the adjusting sleeve 15 to rotate via the adjusting column 6. The adjusting sleeve 15, through the adjusting block 13 and adjusting groove 14, drives the connecting column 11 to rotate, which in turn drives the cone block 501 to rotate. Simultaneously, the materials move through the cone block 501 into the crushing trough 503, where the cone block 501 drives the crushing rack 502 to disperse any clumps of material inside the crushing trough 503. This improves the efficiency of material classification in the device body 1 and solves the problem that the performance of existing fine powder classification devices is greatly affected by material characteristics such as humidity. When the material humidity is high or the materials are highly adhesive, particles easily agglomerate, leading to poor classification results.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
