Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a screening device for a powder loosening machine. Background Art

[0002] The impact loosening machine is a new type of equipment that is indispensable for flour mills to process flaky materials and produce grade flour and special flour. There is an existing patent for an impact loosening machine, with patent announcement number CN214636803U. It includes a working box, the upper surface of the working box is movably connected with a top cover, the upper surface of the top cover is fixedly connected with a feed barrel, the inner wall of the feed barrel is movably connected with a first rolling wheel, the outer surface of the first rolling wheel is meshed with a second rolling wheel, the inner wall of the working box is clamped with a hollow plate, the bottom of the hollow plate is fixedly installed with a first motor, and the output end of the first motor is fixedly connected with a stirring rod. In the impact loosening machine, flour enters from the feed barrel, and the meshing of the first rolling wheel and the second rolling wheel can kill some larvae and eggs in the flour to prevent the flour from being infested with insects after being processed, and can make the flour fall evenly, thus avoiding the blockage of the entrance to a certain extent. The flour falls on the stirring rod and is broken up by it, which is convenient for enhancing the efficiency of loosening the flour in the later stage. The impact plate can produce impact inside the loosening box to achieve the effect of loosening the flour, so that the flour can be processed faster after entering the impact loosening machine, thereby improving the processing efficiency.
