Abstract
Description
Technical Field
[0001] This utility model relates to an independently controlled side-feed classifier, belonging to the field of classifier technology. Background Technology
[0002] Commonly, top-feed classifiers often employ a structure with a spreading disc located above the impeller sorting section. In this structure, the material dispersion and grading processes occur within the same area inside the casing, which can easily interfere with each other and affect the sorting effect. Furthermore, these classifiers typically use a top-feeding elevator, which presents several inconveniences in practical use. Firstly, due to plant height limitations, the elevator cannot reach the top of the classifier for feeding. Secondly, the higher lifting height during top feeding increases the elevator's energy consumption. Thirdly, top feeding requires a separate feeding channel, increasing equipment complexity and manufacturing costs. Moreover, this feeding method is prone to wear between the material and the impeller's drive shaft, leading to increased maintenance costs. Utility Model Content

[0005] The output end of the first power module is connected to the moving part of the impeller module; the material spreading disc is connected to the output end of the second power module.
[0006] The housing module is equipped with a material distribution cone and a middle material channel for receiving the materials sorted by the impeller module; the material discharged from the material distribution cone can be directly conveyed to the spreading plate, or it can pass through the spreading plate and be discharged into the middle material channel.

[0013] The fixed wheel is fixedly connected to the upper shell of the sorting, and the rotating wheel is connected to the first drive shaft; the first power module can drive the rotating wheel to rotate relative to the fixed wheel.
[0014] Furthermore, the material spreading disc has an opening, the material distribution cone is located above the opening of the material spreading disc, and the central material channel is connected below the opening of the material spreading disc.

[0049] An air outlet 201 is provided on the side of the air outlet housing 2; the air outlet housing 2 can be connected to an external fan through the air outlet 201. When the fan is working, the airflow enters the housing module from the air inlet 501 and is discharged from the air outlet 201. At this time, the inside of the housing module is a negative pressure environment.
[0050] An air inlet 501 is provided on the side of the air inlet housing 5; a louvered valve 502 for adjusting the air intake volume is provided on the air inlet 501.

[0055] Specifically, the spreading disc 11 has an opening, the material distribution cone 10 is attached above the opening of the spreading disc 11, and the central material channel 12 is connected below the opening of the spreading disc 11.
[0056] Specifically, the second power module 13 includes a second motor 1301, and a second drive shaft 1302 is connected to the output end of the second motor 1301.
[0057] The second motor 1301 is fixedly connected to the discharge housing 6; the second drive shaft 1302 passes through the housing module; the second drive shaft 1302 passes through the material channel 12 and is connected to the spreading disc 11.
[0058] Specifically, the spreading disc 11 is also provided with several material dispersing blades 1101; when the spreading disc 11 rotates, the material dispersing blades 1101 can disperse the material and enhance the dispersion effect on the material.
[0059] The feeding module 9 includes: an execution component 903, on which a drive component 901 is provided, which can drive the execution component 903 to realize material conveying;
[0060] The execution component 903 is provided with a feed port 902 and a discharge port 904; the discharge port 904 extends into the interior of the distribution cone 10.
[0061] In this embodiment, the execution component 903 is a screw conveyor, and the drive component 901 is a motor; the motor drives the screw conveyor to complete the material conveying. During feeding, the material enters the execution component 903 from the feed inlet 902 and is finally discharged from the discharge outlet 904.
[0062] Specifically, the material distribution cone 10 includes a support cylinder 1005, on the outer wall of the support cylinder 1005, an outer cone 1001 and an inner cone 1002 are spaced apart, and an independent conveying channel 1003 connects the outer cone 1001 and the inner cone 1002, and the material in the inner cone 1002 can be directly discharged from the material distribution cone 10 through the conveying channel 1003.
[0063] The side of the support cylinder 1005 is provided with a number of material conveying holes 1006. The material conveying holes 1006 are located in the interlayer area between the outer cone 1001 and the inner cone 1002.

[0067] The specific working principle of this utility model is as follows:
[0068] When the powder classifier is working, the induced draft fan starts synchronously. Furthermore, the first motor 101 drives the rotating wheel 7 to rotate, and the second motor 1301 drives the spreading disc 11 to rotate. During feeding, the elevator puts the material to be sorted into the feeding module 9. Then, the material to be sorted falls into the inner cone 1002 along the discharge port 904, and then falls directly onto the rotating spreading disc 11 through the conveying channel 1003. The spreading disc 11 evenly throws out and disperses the material. The coarser material with a larger weight falls directly into the discharge shell 6 for collection under the action of gravity. The other lighter material enters the rotating wheel module for secondary sorting with the negative pressure airflow in the shell module.
[0069] In the rotary module, an annular grading zone is formed between the rotary wheel 7 and the fixed wheel 8. The material passes through the blades of the fixed wheel 8 and enters the annular grading zone. It is subjected to the combined effects of the centrifugal force of the rotary wheel 7, the pulling force of the negative pressure airflow, and its own gravity. The lighter fine material passes through the blades of the rotary wheel 7 under the main action of the negative pressure airflow and is discharged to the outside for collection through the air outlet 201. The medium-weight coarse material is moved towards the fixed wheel 8 under the main action of the centrifugal force of the rotary wheel 7 and is finally blocked on the blades of the fixed wheel 8. The medium-weight coarse material is left in the annular grading zone and falls into the interlayer area between the outer cone 1001 and the inner cone 1002 under the action of gravity. Further, the medium-weight coarse material passes through the conveying hole 1006 and enters the support cylinder 1005. Then, the medium-weight coarse material passes through the opening of the spreading plate 11 along the support cylinder 1005 and enters the medium material channel 12, realizing classified discharge.
