[0002] Airflow classifier is an airflow classifying equipment. The classifier, cyclone separator, dust collector and induced draft fan form a classifying system. Under the suction force of the fan, the material moves at high speed from the classifier inlet to the classifying area along with the rising airflow. Under the strong centrifugal force generated by the high-speed rotating classifying turbine, the coarse and fine materials are separated.

[0003] In the existing process of feeding resin raw materials, finer resin raw materials may stick to each other, resulting in poor grading effect inside the entire body. In addition, during the grading process, the resin raw materials that need to be separated inside the entire body cannot be well dispersed, resulting in low grading efficiency and accuracy inside the entire body. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-precision airflow classifier, comprising an airflow classifier housing and a classifying device, the classifying device is arranged inside the airflow classifier housing, the classifying device comprises a feed port, the feed port is fixedly connected to the upper end of the airflow classifier housing and extends to the inside of the airflow classifier housing;

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) The high-precision airflow classifier uses the centrifugal effect of the rotation of the dispersion disk to cause the resin raw material particles to collide with the baffle and the blades, thereby breaking up the resin raw material.

When the blades rotate and revolve around the sun, the resin raw material is evenly distributed in the airflow classifier housing. This even distribution ensures that the resin raw material can be subjected to uniform airflow and centrifugal force, thereby improving the stability and accuracy of the classification process and enhancing the classification efficiency of the device.

[0018] (2) The high-precision airflow classifier, through the use of a wind shield, is convenient for blocking the air entering from the secondary air inlet, which is convenient for the airflow to generate vortexes. The airflow is subjected to the negative pressure generated by the rotation of the baffle and the blades, forming a rotating upward airflow, so that the resin raw material is simultaneously subjected to the centrifugal force, gravity and the force generated by the airflow, so that small particles of the resin raw material float in the air, which is convenient for classifying the resin raw material and improves the classification accuracy and classification effect of the resin raw material.

[0029] See also Figure 1-4The utility model provides a technical solution: a high-precision airflow classifier, comprising an airflow classifier housing 1 and a classifying device, the classifying device is arranged inside the airflow classifier housing 1, the classifying device comprises a feed port 3, the feed port 3 is fixedly connected to the upper end of the airflow classifier housing 1 and extends to the inside of the airflow classifier housing 1, the upper end of the feed port 3 is fixedly connected to a drive motor 8, the output end of the drive motor 8 is fixedly connected to a rotating shaft 9, the rotating shaft 9 is rotatably connected to the feed port 3, the lower end of the rotating shaft 9 is fixedly connected to a dispersion disk 10, the surface of the dispersion disk 10 is fixedly connected to a baffle 14, and the surface of the dispersion disk 10 is rotatably connected to a blade 15.

[0030] There are multiple baffles 14, which are evenly fixed on the outside of the dispersion disk 10 in a ring shape. The grading device also includes a first fixed plate 11, which is fixedly connected to the inside of the airflow classifier housing 1. The lower end of the first fixed plate 11 is fixedly connected to multiple fixed shafts 13, and the multiple fixed shafts 13 are all cylindrical. A second fixed plate 12 is arranged inside the airflow classifier housing 1, the lower end of the feed port 3 is fixedly connected to the second fixed plate 12, and the upper end of the second fixed plate 12 is fixedly connected to multiple fixed shafts 13. The upper end of the blade 15 is fixedly connected to a gear 16, and the lower end of the second fixed plate 12 is fixedly connected to a gear ring 17, the teeth of the gear ring 17 are arranged on the inner side, and the gear 16 and the gear ring 17 are meshed with each other.

[0031] There are multiple blades 15 and gears 16 . The cross-sections of the multiple blades 15 are all crescent-shaped. The multiple gears 16 are all meshed with the gear ring 17 . The multiple blades 15 are rotatably connected to the dispersion disk 10 .

[0032] A resin raw material fine material discharge port 6 is fixedly connected to the eccentric portion of the upper end surface of the airflow classifier housing 1, an air inlet 4 is fixedly connected to the eccentric portion of the surface of the airflow classifier housing 1, a resin raw material coarse material discharge port 5 is fixedly connected to the lower end of the airflow classifier housing 1, and a feed port 2 is fixedly connected to the surface of the feed port 3.

[0033] A wind shield 7 is fixedly connected to the interior of the airflow classifier housing 1 .

[0034] When using the device, first connect the air inlet 4 to the fan, start the drive motor 8 to drive the rotating shaft 9 to rotate, the rotating shaft 9 drives the dispersion disk 10 to rotate, the dispersion disk 10 drives the baffle 14 to rotate, the dispersion disk 10 drives the blades 15 and the gear 16 to rotate, and due to the meshing of the gear 16 and the gear ring 17, the gear 16 rotates during the process of revolving around the rotating shaft 9, and then add the resin raw material from the feed port 2. Under the action of gravity, the resin raw material falls onto the surface of the dispersion disk 10 through the feed port 3. Due to the centrifugal effect, the resin raw material is thrown to the inner wall of the air flow classifier housing 1, and in the process of the resin raw material being thrown out, the resin raw material will collide with the baffle 14 and the blade 15 to break up the resin raw material. Since the blade 15 not only revolves but also rotates, it is convenient to increase the force to break up the resin raw material.

[0035] The resin raw material is blocked when it is thrown toward the inner wall of the air flow classifier housing 1 by the centrifugal action, so that the resin raw material is evenly sprinkled downward to the inside of the air flow classifier housing 1. At the same time, the fan is started to tangentially enter the air flow into the air flow classifier housing 1. The air flow is blocked by the wind shield 7, so that the air flow generates vortex, and the air flow is subjected to the negative pressure generated by the rotation of the baffle 14 and the blades 15, forming a rotating upward airflow, so that the resin raw material is simultaneously subjected to the centrifugal action, gravity and the force generated by the airflow, so that small particles of the resin raw material float in the air and are discharged from the resin raw material fine material discharge port 6 along with the rotating airflow, and the coarser particles of the resin raw material are discharged from the resin raw material coarse material discharge port 5 due to the greater gravity.

[0036] Furthermore, through the centrifugal effect of the rotation of the dispersion disk 10, the resin raw material particles collide with the baffle 14 and the blades 15 to break up the resin raw material. Since the blades 15 not only revolve but also rotate on their own, it is convenient to increase the force of breaking up the resin raw material. When the blades 15 rotate and revolve, the resin raw material is evenly distributed in the airflow classifier housing 1. This uniform distribution ensures that the resin raw material can be subjected to uniform airflow and centrifugal force, thereby improving the stability and accuracy of the classification process and improving the classification efficiency of the device.

[0037] By using the wind shield 7, it is convenient to block the air entering from the secondary air inlet, which makes it convenient for the airflow to generate vortex. The airflow is subjected to the negative pressure generated by the rotation of the baffle 14 and the blades 15, forming a rotating upward airflow, so that the resin raw material is simultaneously subjected to the centrifugal effect, gravity and the force generated by the airflow, so that small particles of the resin raw material float in the air, which makes it convenient to classify the resin raw material and improves the classification accuracy and classification effect of the resin raw material.

[0038] Working principle: When using the device, first connect the air inlet 4 to the fan, start the drive motor 8 to drive the rotating shaft 9 to rotate, the rotating shaft 9 drives the dispersion disk 10 to rotate, the dispersion disk 10 drives the baffle 14 to rotate, and the dispersion disk 10 drives the blades 15 and the gear 16 to rotate. Due to the meshing of the gear 16 and the gear ring 17, the gear 16 rotates during the process of revolving around the rotating shaft 9, and then add the resin raw material from the feed port 2. Under the action of gravity, the resin raw material falls onto the surface of the dispersion disk 10 through the feed port 3. Due to the centrifugal effect, the resin raw material is thrown to the inner wall of the airflow classifier housing 1, and in the process of the resin raw material being thrown out, the resin raw material will collide with the baffle 14 and the blade 15 to break up the resin raw material. Since the blade 15 not only revolves but also rotates, it is convenient to increase the force to break up the resin raw material.

[0039] The resin raw material is blocked when it is thrown toward the inner wall of the air flow classifier housing 1 by the centrifugal action, so that the resin raw material is evenly sprinkled downward to the inside of the air flow classifier housing 1. At the same time, the fan is started to tangentially enter the air flow into the air flow classifier housing 1. The air flow is blocked by the wind shield 7, so that the air flow generates vortex, and the air flow is subjected to the negative pressure generated by the rotation of the baffle 14 and the blades 15, forming a rotating upward airflow, so that the resin raw material is simultaneously subjected to the centrifugal action, gravity and the force generated by the airflow, so that small particles of the resin raw material float in the air and are discharged from the resin raw material fine material discharge port 6 along with the rotating airflow, and the coarser particles of the resin raw material are discharged from the resin raw material coarse material discharge port 5 due to the greater gravity.

[0040] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
