Description

Technical Field

[0001] This utility model relates to the field of fine sorting machine technology, and in particular to a fine sorting machine with a multi-stage multiple separation unit. Background Technology

[0002] In fields such as mineral processing, grain sorting, and chemical raw material screening, the fine selection and screening of materials is a key link in improving product quality. A fine selection machine is a device used to screen and classify materials. It usually has a specific working principle and structure, and can classify materials into different grades or categories according to different characteristics such as size, shape, weight, and density.

[0003] Traditional material sorting machines typically use single vibrating screens or airflow separation to screen materials. However, materials tend to accumulate during the feeding stage, resulting in uneven distribution, which affects the efficiency and accuracy of subsequent screening. Furthermore, light impurities such as dust are difficult to separate effectively, which can easily lead to a decrease in product purity. Therefore, a material sorting machine with a multi-stage separation unit is proposed to address the above problems. Utility Model Content

[0024] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0025] This utility model provides a technical solution:

[0026] Reference Figure 1-6A fine separator with a multi-stage separation unit includes a base frame 1. A support frame 2 is fixedly installed on the top surface of the base frame 1. A screening channel 3 is installed on the top surface of the base frame 1 via multiple second spring telescopic rods 26. A first vibration motor 8 is fixedly installed on both outer sides of the screening channel 3. A material distribution box 4 is installed on the top surface of the support frame 2 via multiple first spring telescopic rods 10. A second vibration motor 9 is fixedly installed on both outer sides of the material distribution box 4. It should be noted that the bottom walls of the material distribution box 4 and the screening channel 3 are inclined, so that when the material distribution box 4 and the screening channel 3 vibrate, the material gradually moves towards its opening under its own gravity. Under the action of the first spring telescopic rods 10 and the second spring telescopic rods 26, the material distribution box 4 and the screening channel 3 can only vibrate up and down.

[0027] A drive box 5 is fixedly installed on the top surface of the material distribution box 4. Sliding plates 21 are slidably connected to the inner walls on both sides of the drive box 5. Multiple vertical rods 24 are fixedly installed on the bottom surface of each sliding plate 21. A short-stroke reciprocating sliding mechanism is provided inside the drive box 5, and the short-stroke reciprocating sliding mechanism drives the two sliding plates 21 to slide back and forth in opposite directions. A conveying channel 6 is fixedly connected to one side of the material distribution box 4. A guide channel 13 is fixedly connected to the outside of the screening channel 3. An elastic connecting channel 12 is installed on the top surface of the guide channel 13 and the bottom surface of the conveying channel 6. A dust removal mechanism is provided on the top surface of the base frame 1, and the dust removal mechanism is connected to the elastic connecting channel 12. A screening mechanism is provided inside the screening channel 3. It should be noted that the upper and lower ends of the elastic connecting channel 12 are made of rubber material, so that the screening channel 3 and the material distribution box 4 can maintain a sealed connection with the elastic connecting channel 12 during vibration.

[0028] Furthermore, the short-stroke reciprocating sliding mechanism includes a servo motor 18, which is fixedly mounted on the top surface of the drive box 5. The output shaft of the servo motor 18 is connected to a rotating shaft 19 via a coupling. A drive gear 23 is mounted on the bottom end of the rotating shaft 19. A toothed plate 22 is fixedly mounted on the outer side of each sliding plate 21, and each toothed plate 22 meshes with the drive gear 23. By rotating the servo motor 18 in both directions, the two toothed plates 22 can slide back and forth towards each other. Thus, by setting multiple vertical rods 24, multiple vertical rods 24 set on the bottom surface of each sliding plate 21 can slide towards each other, thereby ensuring uniform material feeding and preventing material accumulation that would reduce subsequent screening accuracy.

[0029] Furthermore, the dust removal mechanism includes multiple collection bins 7, which are fixedly installed on the top surface of the base frame 1. Each collection bin 7 has a discharge pipe 17 fixedly connected to its outer side and a vent pipe 16 fixedly connected to its outer side. Multiple fans 14 are fixedly installed on the top surface of the base frame 1, and the exhaust end of each fan 14 is connected to the corresponding collection bin 7. A dust removal plate 15 is fixedly installed on the top surface of the base frame 1, and the dust removal plate 15 is connected to the elastic connecting channel 12. The air inlet end of each fan 14 is connected to the dust removal plate 15. Each discharge pipe 17 is equipped with a valve.

[0030] Furthermore, the screening mechanism includes a screening plate 25, which is fixedly installed on the side wall of the screening channel 3. One end of the guide channel 13 is fixed and installed on the outside of the screening channel 3, and the connection height between the guide channel 13 and the screening channel 3 is greater than the height of the screening plate 25. The bottom surface of the screening channel 3 is provided with a first opening 27 and a second opening 28.

[0031] Furthermore, a filter plate is fixedly installed on the outside of each dust removal plate 15. The filter plate is mainly used to block materials and does not affect the passage of floating impurities such as dust. A dustproof net is fitted on the outside of each vent pipe 16. The dustproof net is used to block dust and other impurities and does not affect its air permeability.

[0032] Furthermore, two guide plates 11 are symmetrically installed on the bottom wall of the material distribution box 4, and the two guide plates 11 are in a figure-eight shape, so that the material can be separated by multiple vertical rods 24. Guide rails 20 are fixedly installed on both sides of the inner wall of the drive box 5, and each sliding plate 21 is slidably connected to the guide rail 20 corresponding to its position.

[0033] In practical use, the working principle of this utility model is as follows:

[0034] In this utility model, when the device is used, the operator first places the material on the top surface of the equalization box 4, then starts multiple second vibration motors 9, and under the action of multiple first spring telescopic rods 10, the equalization box 4 vibrates up and down. Then, the servo motor 18 is started to drive the rotating shaft 19 to rotate, and then through the meshing of the drive gear 23 and the toothed plate 22, the two toothed plates 22 slide towards each other. Through the forward and reverse rotation of the output shaft of the servo motor 18, the two toothed plates 22 slide back and forth towards each other, thereby driving multiple vertical rods 24 to slide back and forth towards each other, which facilitates blocking and scattering of the material. Thus, under the vibration of multiple equalization boxes 4, the material gradually enters the conveying channel 6, avoiding material accumulation and affecting the subsequent screening accuracy.

[0035] Next, the material entering the conveying channel 6 falls freely in the elastic connecting channel 12 under the action of gravity, which facilitates the separation of the material from floating impurities such as dust. At this time, multiple fans 14 can be started. The multiple fans 14 extract the floating impurities in the elastic connecting channel 12 through the dust extraction plate 15. The filter plate on the outside of the dust extraction plate 15 can prevent the material from entering the fan 14. Then the fan 14 conveys the impurities to the collection bucket 7, and the dust and other impurities are blocked by the dustproof net installed on the outside of the vent pipe 16. Thus, the impurities accumulate in the collection bucket 7 under the action of gravity, and can be discharged through the discharge pipe 17 later.

[0036] Next, the material after impurities are removed falls onto the top surface of the screening plate 25 through the guide channel 13. With the help of multiple second spring telescopic rods 26 and multiple first vibration motors 8, the screening channel 3 vibrates up and down. As a result, the material gradually moves towards the opening on the top surface of the screening plate 25. Smaller materials fall onto the bottom wall of the screening channel 3 and are discharged through the second opening 28, while larger materials are discharged through the first opening 27, thus completing the fine screening of the material.

[0037] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
