Description

TECHNICAL FIELD

[0001] The utility model relates to a device for removing impurities, and particularly relates to a device for removing impurities used in the production of stone-ground flour. BACKGROUND

[0003] In the production process of stone-ground flour, a device for removing impurities is needed to remove particulate impurities in the flour and raw materials that have not been pulverized to a specified size. The patent with publication number CN220461260U discloses a device for removing impurities from wheat flour, which can drive and install the device according to the caking of the flour, rotate and crush the device, and improve the reliability of the device. The device includes a screening mechanism, which is used to screen out wheat flour to remove impurities.

However, the device for removing impurities from wheat flour cannot remove impurities of different sizes in layers, which reduces the efficiency of removing impurities. Moreover, the flour is directly discharged after being removed of impurities, and there is no collection mechanism to fully collect the flour. Therefore, the present application proposes a device for removing impurities used in the production of stone-ground flour. SUMMARY

The rotation of the vertical shaft 409 drives the suction fan blades 4012 to rotate. The rotation of the suction fan blades 4012 exhausts the air in the collection box 401, so that the powder suction pipe 403 can effectively adsorb the impurity-removed stone-ground flour through the bottom of the rotating drum 302, and quickly collect it through the collection bag 402, thereby achieving the purpose of automatic collection of stone-ground flour.
