Specific embodiment

The content of the utility model is illustrated below in conjunction with attached drawing.

As shown in Figure 1, the schematic diagram of the improved flour mill of the utility model.Improved flour mill includes flour mill shell, The intracorporal top of flour mill shell is equipped with and grinds A surely, and the middle part feeding-passage for grinding A surely is connected to feed hopper, and pressure roller is equipped in feed hopper Group, pressure roller group include the pressure roller A rotated clockwise being arranged in juxtaposition, the pressure roller B rotated counterclockwise, are fed through pressure roller A, pressure roller B Between carry out preliminary working.Surely the lower section for grinding A is equipped with dynamic mill, and the lower section of dynamic mill is equipped with grinds B surely, and the lower section for grinding B surely is equipped with powder storage chamber, storage The lower section of powder room is equipped with dynamic mill driving motor, moves mill driving motor by transmission shaft and drives dynamic mill rotation milling, through at the beginning of pressure roller group The charging of processing is discharged into powder storage chamber after grinding the time processing of A, dynamic mill and the secondary operation of mill B surely through dynamic mill and surely.Above scheme Using the scheme of the attrition process twice of preposition preliminary working, processing quality greatly improved.

In order to further increase processing quality, the function of dynamic mill is realized, the dynamic mill of this programme is column structure, moves the upper of mill The edge department of abradant surface is equipped with accumulated powder annular groove, and the depth of one end of accumulated powder annular groove is greater than the depth of the other end of accumulated powder annular groove, The slot bottom of accumulated powder annular groove one end is equipped with defeated powder channel, and the outlet in defeated powder channel is located at the middle part of the lower abradant surface of dynamic mill, charging warp Dynamic mill is discharged with after the time processing for grinding A surely by the defeated powder channel of accumulated powder annular groove.As shown in Figure 1, 2, 3, it is moved mill and grinds A surely The powder of attrition process is processed by accumulated powder annular groove, second of the progress of defeated powder channel, is scattered, be ensure that all without powder therebetween Powder is all processed by second, to improve processing quality.

In order to realize second of attrition process, and the function of B is ground surely, the mill B that determines of this programme includes grinding column B, fixed mill Pilum B, the outer diameter of grinding column B are less than the outer diameter for grinding pilum B surely, and grinding column B, mill pilum B forms second level pylon structure surely, fixed to grind The level height of one end of pilum B grinds the one end pilum B surely and is equipped with defeated powder lower than the level height for the other end for grinding pilum B surely Channel B, defeated powder channel B are connected to powder storage chamber, are overflowed and are passed through after dynamic mill and the secondary operation of mill B surely through the powder of time processing Defeated powder channel B enters powder storage chamber.As shown in figures 1,4 and 5, it is dissipated with the powder for grinding B attrition process surely from spilling between the two through dynamic mill It falls, enters powder storage chamber from defeated powder channel B.Further, in order to improve the quality of second of processing, the grinding column B's of this programme is ground Flour milling is equipped with the involute arc slot extended from center, and involute arc slot extends to the outer of the abradant surface of grinding column B Portion, involute arc slot guide powder to move along helical path to the outer of the abradant surface of grinding column B.This programme can also pass through Increase milling area to improve processing quality, i.e., the lower abradant surface of dynamic mill is the circular cone table top of indent, and it is convex for grinding the abradant surface of B surely The circular cone table top risen, the lower abradant surface for moving mill form second of attrition process with the abradant surface for grinding B surely and cooperate, and the discharging of grinding is logical Road is the path for tilting down extension, is conducive to powder spilling.

The powder discharge completed in order to facilitate processing, the level height of one end of the bottom of the powder storage chamber of this programme is lower than storage The level height of the other end of the bottom of powder room, the outside of the bottom end of powder storage chamber are equipped with powder channel, in powder storage chamber Powder is discharged by powder channel.

The improved flour mill of this programme is led to using the scheme of the attrition process twice of preposition preliminary working using built-in defeated powder The dynamic mill in road avoids being scattered by the powder of time processing, is mentioned using improved mill B surely and the dynamic fit system for grinding and grinding B surely The quality of high secondary operation.Based on the above feature, the improved flour mill of this programme has substantive special compared to existing product Point and progress.

The improved flour mill of this programme is not limited to content disclosed in specific embodiment, the skill occurred in embodiment Art scheme can the understanding based on those skilled in the art and extend, those skilled in the art are according to this programme combination common knowledge The simple replacement scheme made also belongs to the range of this programme.
