[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a double-air-inlet raw material vertical mill device, comprising a main body 1, an exhaust pipe 11 is connected to the upper end of the main body 1, and a relative air inlet 12 is arranged on the side of the main body 1. The exhaust pipe 11 drives the air in the main body 1 to flow and discharge from the top, and the air inlet 12 is symmetrically distributed to make the internal wind force distribution more uniform. A feeding component 2 is arranged on one side of the main body 1, and a grinding component 3 is arranged on the side of the main body 1. A grinding disc 4 is arranged under the grinding component 3 in the main body 1, and a sieve hole 41 is arranged on the grinding disc 4. A collecting component 5 is slidably connected under the grinding disc 4 on the inner side of the main body 1, and the collecting component 5 comprises a collecting bin 51 and a pulley 52. ​​The collecting bin 51 is located on the inner side of the main body 1, and the lower end of the collecting bin 51 is fixedly connected to the pulley 52. ​​A slide groove 53 adapted to the pulley 52 is arranged at the bottom of the main body 1, and the collecting bin 51 collects the material falling from the sieve hole 41, so as to facilitate the sliding removal of the collecting bin 51 and the subsequent further processing of the material.

[0025] Embodiment 2

[0026] On the basis of Example 1, the grinding assembly 3 includes a grinding roller 31 and a driving motor 32. The driving motor 32 is located on the outside of the main body 1. The output shaft of the driving motor 32 is connected to the grinding roller 31. The driving motor 32 drives the grinding roller 31 to grind the material on the grinding disk 4. The feeding assembly 2 includes a feeding pipe 21 and a slide plate 22. The feeding pipe 21 is obliquely arranged on the side of the main body 1 and is connected to the main body 1. The upper end of the feeding pipe 21 is provided with a through hole adapted to the slide plate 22. The slide plate 22 is slidably connected to the through hole of the feeding pipe 21. The material is placed into the main body 1 by pulling up the slide plate 22, and the dust is prevented from overflowing by lowering the slide plate 22. A holding hole 23 is provided on the upper end of the slide plate 22 for easy extraction and use of the slide plate 22. The screening hole 41 is located on the outside of the grinding disk 4. The grinding assembly 3 is relatively arranged on both sides of the main body 1, thereby improving the grinding efficiency.

[0027] The working principle of this application is as follows: by providing a relative air inlet 12 on the side of the main body 1, the exhaust pipe 11 drives the air in the main body 1 to flow and discharge from the top, and the air inlet 12 is symmetrically distributed to make the internal wind force distribution more uniform. As the grinding progresses, the ground powder will fall from the sieve hole 41 into the collection bin 51. After the grinding is completed, the collection bin 51 can effectively collect the material falling from the sieve hole 41, which is convenient for sliding the collection bin 51 out and further processing the material in the future. This patent sets the sieve hole 41 with the collection component 5, and does not require additional power equipment for flipping and screening, reducing the energy consumption of the device, and at the same time facilitating the collection and processing of the ground material, and sets the relative air inlet 12 to make the wind force distribution in the main body 1 more uniform, effectively controlling the airflow in the mill.
