DETAILED DESCRIPTION

[0019] In order to make the technical problem, technical scheme and beneficial effect that the utility model wants to solve more clearly, the following combines the drawing and example, and further detailed explanation of the utility model is conducted.

[0020] As Figure 1 The utility model discloses simple structure, convenient installation, through the drainage tube with the hopper, negative pressure air suction structure intercommunication, make the float powder, ash bypass the grinding system of flour mill, guarantee the surface roughness of grinding roller, will not be influenced by float powder, ash and become smooth, improve the service life of grinding roller, and material can be fully ground, reduce material tabletting phenomenon, improve the powder quality of going out, and through the control of air volume adjusting device, prevent material from being sucked away when negative pressure wind is too big.

[0021] In the embodiment, the drainage tube 1 is arranged on the support frame 4, and the support frame 4 is fixedly connected in the flour mill. The drainage tube 1 is arranged outside the grinding system 6 to avoid interference with the grinding work.

[0022] As shown in Figure 2 and Figure 3 The air volume adjusting device 2 includes an adjusting end 2-1 and a fixed end 2-2, and the adjusting end 2-1 is rotationally connected with the fixed end 2-2.

[0023] In the embodiment, the observation cylinder 3 includes a feeding space 3-1 for feeding materials and a cylinder wall inner cavity 3-2 formed by the shell of the observation cylinder 3, and an observation window is further arranged on the side wall of the observation cylinder 3.

[0024] The fixed end 2-2 is arranged on the inner wall of the observation cylinder 3, and a first air port 2-2-1 is arranged on the fixed end 2-2 and communicates with the feeding space 3-1 in the observation cylinder 3.
