Description

Technical Field

[0001] This utility model relates to an independently controlled air classifier, belonging to the field of air classifier technology. Background Technology

[0002] At present, top-feed classifiers are widely used. In this type of classifier, the feeding disc is set at the top of the rotary grading mechanism, and the material dispersion and grading processes are completed in the same working space inside the shell.

[0003] This type of air classifier has the following disadvantages: During material selection, the rotary classifier uses wind power to suck up the scattered material. Since the rotary classifier and the spreading plate are set up close to each other, some material is not completely scattered and is directly sucked into the rotary classifier. The material scattering and classification process is disturbed. At the same time, the rotary classifier cannot obtain material that meets the classification requirements, which also leads to incomplete material classification and affects the classification effect.

[0048] The material to be sorted is independently conveyed to the spreading disc 9 through the guide pipe 2 and the distributing cone 8, ensuring that the material dispersion process is carried out independently. The guide pipe 2 and the distributing cone 8 are designed to ensure that the material is separated from the impeller module during the feeding process, thereby avoiding the material to be sorted from being interfered with by both the impeller module and the spreading disc 9, so that the material dispersion and sorting operations are carried out in an orderly manner; the impeller module and the spreading disc 9 are independently set up vertically within the shell module to ensure that the material sorting and dispersion processes can be carried out independently and without interference.

[0050] The second transmission assembly 13 includes a second motor 1301 disposed on the housing module, and the second motor 1301 is coaxially connected to a second transmission shaft 1302.

[0051] Specifically, the impeller module includes a rotor 4 and a fixed impeller 5. The rotor 4 is connected to the first drive shaft 102; the fixed impeller 5 is connected to the housing module. In this embodiment, both the rotor 4 and the fixed impeller 5 are cylindrical, and both the rotor 4 and the fixed impeller 5 are provided with a number of blades. Preferably, the arrangement density and angle of the blades on the rotor 4 and the fixed impeller 5 can be adjusted according to the sorting requirements of different particle sizes.

[0052] The spreading disc 9 is connected to the second drive shaft 1302.

[0053] Specifically, the discharge port of the feed pipe 2 is connected to the inner hopper 802; the interlayer between the outer hopper 801 and the inner hopper 802 is connected to the bottom of the rotating wheel 4 and the fixed wheel 5.

[0054] Specifically, the lower end of the middle cylinder 805 is connected to a material channel 11. One end of the material channel 11 is a material distribution port 1101. Furthermore, the material distribution port 1101 can be set inside the discharge housing 12 to discharge the material into the discharge housing 12; the material distribution port 1101 can also be led out to the outside of the discharge housing 12 as a separate material outlet for collecting the material.

[0055] Specifically, the interior of the inner hopper 802 is also equipped with a material unloading platform 804, which is conical in shape. Figure 2 As shown, the function of the material discharge platform 804 is to guide the material in the inner hopper 802 to the outer feeding channel 803.

[0056] Specifically, the housing module includes, from top to bottom, an air outlet housing 3, a graded upper housing 6, a graded lower housing 7, an air inlet housing 10, and a material outlet housing 12.

[0057] A material valve 14 is provided on the discharge port of the discharge housing 12.

[0058] Specifically, the air outlet housing 3 is provided with a feeding port 301 and an exhaust port 302, and the feeding port 301 is connected to the feed inlet of the guide pipe 2.

[0059] An air inlet 1001 is provided on the air inlet housing 10, and an air valve 1002 can be optionally installed on the air inlet 1001.

[0060] Specifically, the fixed wheel 5 is connected to the inner wall of the upper grading housing 6; the material distribution cone 8 is connected to the inner wall of the lower grading housing 7.

[0061] The first motor 101 is mounted on the air outlet housing 3; the second motor 1301 is mounted on the air inlet housing 10.

[0062] The specific working principle of this utility model is as follows:

[0063] When the air classifier is working, it is also connected to an external induced draft fan and a dust collector, which together form a complete material sorting and collection system. The dust collector and the induced draft fan are connected in series to the exhaust port 302. When the induced draft fan is working, it generates a negative pressure in the housing module, flowing from the air inlet 1001 to the exhaust port 302, which has a pulling force on the material. When the air classifier is working, the inside of the housing module is maintained in a negative pressure environment. Furthermore, the sorted material particles are sucked out with the airflow to form a mixture. The dust collector filters this mixture and collects the material particles in the dust collector for subsequent use. When the air classifier is working, air enters the air inlet housing 10 from the air inlet 1001. The airflow passes sequentially through the lower classification housing 7, the upper classification housing 6, the impeller module, and the exhaust housing 3, and is finally delivered to the externally connected dust collector from the exhaust port 302.

[0064] After the powder mill is started, the first motor 101 drives the rotor 4 to rotate, and the rotation of the rotor 4 generates centrifugal force. The second motor 1301 drives the spreading disc 9 to rotate, and the rotation of the spreading disc 9 generates centrifugal force.

[0065] During material sorting, firstly, the material enters the inner hopper 802 from the feeding port 301 through the guide pipe 2. The inner hopper 802 is used to receive the material. Further, the material passes through the feeding channel 803 and falls onto the rotating spreading disc 9. Under the centrifugal force of the spreading disc 9, the material is evenly scattered into the air inlet shell 10. Among the scattered material, the larger coarse particles can completely overcome the upward pulling force generated by the airflow in the shell module due to their own gravity, and then fall directly into the discharge shell 12, completing the sorting of coarse materials.

[0066] Furthermore, the lighter medium and fine materials rise with the airflow and enter the impeller module for further sorting: in the impeller module, the materials are subjected to the combined force of the airflow pulling force, the centrifugal force of the impeller 4, and their own gravity.

[0067] First, the small particle size and light weight of the powder can overcome the centrifugal force and gravity it is subjected to by the airflow. The resultant force on the powder is directed towards the inside of the rotor 4. Then, it passes through the rotor 4 with the negative pressure airflow provided by the induced draft fan and is sucked into the dust collector for collection.

[0068] Secondly, the medium-sized material, which has a medium particle size and weight, can overcome the pulling force of the negative pressure airflow by its own centrifugal force and gravity. The resultant force on the medium material is directed towards the inside and outside of the rotor 4. Therefore, the medium material fails to enter the rotor 4 and is discharged with the airflow of the induced draft fan.

[0069] Furthermore, the medium material enters the interlayer between the rotor 4 and the fixed rotor 5 under the action of centrifugal force. On the other hand, after the centrifugal force weakens, the medium material falls into the interlayer between the outer hopper 801 and the inner hopper 802 under the action of gravity. Further, the medium material enters the middle cylinder 805 through the discharge port 806, and is finally discharged through the medium material channel 11. The distribution port 1101 can be set inside the discharge shell 12 or connected to the outside of the classifier. Through the above settings, the medium material can be discharged to different locations for collection.

[0070] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
