Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

The easy-to-clean flour mill of the embodiment, referring to fig. 1-5, includes a mill shell 11 installed on a frame 9, an air inlet 8 and a feed inlet 12 are opened on the side wall of the mill shell 11, a mill core assembly 10 for pulverizing materials is installed in the mill shell 11, the mill core assembly 10 is driven by a power mechanism to work, a guide ring 6 and a gear ring 5 are installed in the mill shell 11, the backflow ring 4, the guide ring 6, the gear ring 5 and the backflow ring 4 are sequentially assembled and connected from bottom to top to form an annular inner layer, an air cavity structure 18 is formed between the side wall of the grinding shell 11 and the annular inner layer, a grading impeller 13 is arranged in the backflow ring 4, a grinding cover 3 is installed at the top of the grinding shell 11 and is driven by an air cylinder 7 to lift, a discharging chamber 2 communicated with the annular inner layer is arranged above the grinding cover 3, a discharging port 19 is formed in the side wall of the discharging chamber 2, the discharging port 19 is connected with an external ventilator, and a first motor 1 used for driving the grading impeller 13 to work is installed at the top of the discharging chamber 2;

The power mechanism comprises a second motor 17 arranged on the frame 9, the second motor 17 is in drive connection with a triangular belt 14 through a belt pulley 15, the triangular belt 14 is in linkage with the grinding core assembly 10, the grinding core assembly 10 comprises a circular grinding disc body 20, a plurality of spaced striking columns 21 are arranged on the upper surface of the grinding disc body 20 along the circumferential direction, and a plurality of spaced retaining rings 22 are arranged on the lower surface of the grinding disc body 20 along the circumferential direction; when the grinding disc machine works, the power mechanism drives the grinding disc body 20 to rotate at a high speed, the crushed materials are lifted by wind power, pass through the grading impeller 13 and enter the particle size optimizing machine or the cyclone separator through the discharge hole 26;

in the milling machine production process, because the material is beaten by the crushing disc machinery and is beaten and produce unordered motion, some materials can be beaten and get into in the joint face of ring gear 5 and backward flow circle 4, consequently need take out ring gear 5 and backward flow circle 4 and carry out the complete machine clearance when clearing up the milling machine, add air cavity structure 18 after, the operation workman can directly take out quick clearance with ring gear 5 and backward flow circle 4 from the mill shell 11 inside. Due to the high speed rotation of the core assembly 10, the air flow and the material are simultaneously agitated at a high speed, which generates a loud noise. In the original structure, the gear ring and the backflow ring are in close contact with the inner cavity of the grinding shell 11, and the transmission condition of noise in metal is far stronger than that in air, so that the noise level is greatly reduced after the air cavity structure is added.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
