[0022] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme in the present application will be described clearly and completely in combination with the drawings in the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.
[0023] The present application will be further described in detail in combination with the drawings.
[0024] The air inlet of the existing impact mill is arranged on the upper end face of the main shell, and the air flow entering the main shell from the air inlet and the feed inlet is inconsistent, which causes the raw materials and the air flow entering the main shell to be mixed smoothly.
[0025] Referring to Figs. 1 to 3 As shown in the figure, the improved impact mill comprises a main shell 8, a feeding pipe 1, a main shaft 2, an air door 3, a lining plate 6, an impact disc 7, a classification wheel 9, a classification machine neck 10, and an air inlet volute 11. The air inlet volute 11 is arranged at the center of the left end face of the main shell 8, and the main shaft 2 passes through the air inlet volute 11 and is arranged at the axial center of the air inlet volute 11. The impact disc 7 is arranged at the right end face of the main shaft 2. The axial center line of the air inlet volute 11 coincides with the axial center line of the main shell 8. An annular gap is arranged between the inner wall of the air inlet volute 11 and the outer wall of the main shaft 2. The lining plate 6 is arranged on the left side of the inner wall of the main shell 8. The classification wheel 9 is arranged on the right side of the inner wall of the main shell 8. The classification machine neck 10 is arranged on the right side of the classification wheel 9. One end of the feeding pipe 1 is connected to the air inlet volute 11 through a connecting piece 13. The other end of the feeding pipe 1 is connected to the air door 3. The feeding pipe 1 and the connecting piece 13 are provided with a feed inlet 12 therebetween. During operation, the powder raw materials enter from the feed inlet, and the air enters from the air door. The air flow carries the powder raw materials into the air inlet volute through the feeding pipe, and enters the inside of the main shell from the annular gap between the inner wall of the air inlet volute and the outer wall of the main shaft. The size of the air flow can be adjusted by the air door. The powder raw materials entering the inside of the main shell impact, shear and crush the lining plate on the impact disc rotating at high speed and the lining plate on the inner wall of the main shell. The crushed powder particles reach the periphery of the classification wheel under the action of the air flow. Because the classification wheel rotates at high speed to generate centrifugal force, the fine powder particles with small centrifugal force are carried into the inside of the classification wheel by the air flow and are discharged through the classification machine neck. The coarse particles are thrown to the inner wall of the main shell under the action of the centrifugal force of the classification wheel. Because the impact disc rotates at high speed to generate negative pressure, the coarse particles enter the impact disc and the lining plate again under the joint action of the negative pressure and the air flow entering the air inlet volute to impact and shear and crush. The crushed powder particles reach the periphery of the classification wheel again under the action of the air flow to be classified, and the process is repeated. The positions, connection relationship and connection structure of the feeding pipe, the air inlet volute, the air door and the feed inlet are beneficial to the smooth mixing of the raw materials and the air flow. Because the air inlet volute replaces the air inlet and the feed inlet on the main shell, the air inlet and the feed inlet are combined into one, the air flow carries the powder raw materials into the main shell through the feeding pipe and the air inlet volute to be crushed, the mixing of the raw materials and the air flow entering the main shell is smooth, which is beneficial to improving the crushing efficiency.

[0027] In one embodiment, the rear section of the feeding pipe 1 is arranged as an upwardly raised slope, and the slope of the rear section of the feeding pipe is adapted to the height of the main shell.
[0028] In one embodiment, the feeding port 12 is arranged at the front section of the feeding pipe, and the powder raw material enters the feeding pipe from the feeding port.
[0029] In one embodiment, the shape of the feeding port 12 includes a funnel type, and the funnel type feeding port is beneficial to the addition of the raw material.
[0030] In one embodiment, the connecting piece 13 includes a bolt, the air inlet volute is provided with an inlet, and the inlet is tangentially arranged on the outer circle of the air inlet volute, and the tangential arrangement of the inlet makes the air inlet more smooth and the airflow has a rotating effect, the rotating airflow enhances the carrying effect of the powder particles, and further improves the crushing efficiency; the diameter of the rear section of the feeding pipe is consistent with the diameter of the inlet of the air inlet volute, and the end face of the rear section of the feeding pipe is combined with the end face of the inlet of the air inlet volute after being fixed by the bolt. Further, a sealing piece can be arranged at the end face of the rear section of the feeding pipe and the end face of the inlet of the air inlet volute, and the sealing piece makes the end face of the rear section of the feeding pipe and the end face of the inlet of the air inlet volute have better sealing performance.
