Abstract
Description
Technical Field
[0001] This application relates to the technical field of air classifiers, and in particular to a sorting mechanism for an air classifier. Background Technology
[0002] Air classifiers are widely used in coal mill raw meal drying mills and cement mill systems in new dry process cement production lines. They can be divided into three main categories: three-stage air classifiers, centrifugal air classifiers, and cyclone air classifiers. Currently, when refining powder materials, sorting mechanisms are required to screen them. However, existing sorting mechanisms often use vibration filtration to process powder materials of different sizes. This causes the powder to shake and discharge fine powder within a filter chamber, which can easily lead to coarse powder accumulating on the filter screen. This prevents the fine powder on top of the coarse powder from falling off, reducing the sorting efficiency. Utility Model Content

Multiple classifying plates are fixedly connected to the inner sidewall of the classifying box. Two screens are fixedly installed on the sidewalls of each of the multiple classifying plates. A discharge plate is fixedly connected to the bottom of the inner sidewall of the classifying box. Multiple discharge ports are evenly distributed on the sidewall of the classifying box. One end of each classifying plate and discharge plate is located inside the discharge port. Multiple support legs are located at the bottom of the classifying box, and the top ends of each support leg are fixedly connected to the lower surface of the classifying box via springs. A vibration motor is located at the bottom of the classifying box.

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0017] This application discloses a sorting mechanism for an air classifier. (Refer to...) Figure 1-3 A classifying mechanism for an air classifier includes a classifying box 1, which is hollow inside. A feed inlet 2 is located on the upper surface of the classifying box 1. Multiple classifying plates 9 are fixedly connected to the inner sidewall of the classifying box 1. Two screens 11 are fixedly installed on the sidewalls of each of the multiple classifying plates 9. The aperture of the multiple sets of screens 11 decreases sequentially from top to bottom. A discharge plate 10 is fixedly connected to the bottom of the inner sidewall of the classifying box 1. Multiple discharge ports 4 are evenly distributed on the sidewall of the classifying box 1. One end of each of the classifying plates 9 and the discharge plate 10 is located inside the discharge port 4. Multiple inclined guide plates 5 are fixedly connected to the outer wall of the sorting box 1. One end of the guide plate 5 is connected to the discharge port 4. Baffles 6 are symmetrically fixedly connected to the upper surface of the guide plate 5. An observation window 3 is fixedly installed on one side of the sorting box 1. Multiple support legs 7 are installed at the bottom of the sorting box 1. The top of each support leg 7 is fixedly connected to the lower surface of the sorting box 1 by a spring 8. A vibration motor (not shown in the figure) is installed at the bottom of the sorting box 1. The vibration motor is existing technology and widely used in society, so it will not be described in detail.
[0018] The implementation principle of the powder classifier's sorting mechanism in this application embodiment is as follows: All electrical components in this application are externally connected to a power supply and control switch during use. During use, powder falls into the sorting box 1 from the feed inlet 2. A vibration motor drives the sorting box 1 to vibrate up and down along the support legs 7 and springs 8. Multiple sorting plates 9 are arranged in a stepped manner within the sorting box 1, with the mesh size of the screens 11 of each sorting plate 9 decreasing progressively. During vibration, fine powder passes through the screens 11 layer by layer, while coarse powder moves along the inclined surface of the sorting plates 9 towards the corresponding discharge port 4, achieving multi-particle size classification. A guide plate 5 is inclined to connect the discharge port 4 to an external collection device, and its baffle 6 prevents powder splashing while guiding the material along a designated path. The observation window 3 is made of transparent, wear-resistant glass, allowing real-time observation of the material flow within the sorting box 1, facilitating adjustment of vibration parameters or cleaning of the screens 11. Finally, the screened powder slides along the feed plate 10 towards the discharge port 4. The vibration causes the powder to form a uniform layer on the screen 11, preventing coarse powder from accumulating and clogging the screen holes.
[0019] This process, through vibrating screening and multi-layer grading, solves the problems of low efficiency and frequent clogging in traditional sorting methods, making it particularly suitable for the fine sorting of cement and mineral powders. Its high efficiency, low consumption, and easy maintenance characteristics can significantly improve the production efficiency and environmental protection level of the powder processing industry, and it has significant industrial application value.
