The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiments the utility model is described in further detail:
It is as shown in Figure 1,
A kind of particulate negative pressure of the utility model flour mill comprises machine barrel 10, pay-off 20, crushing wheel 30, grading wheel 40, suction tube 50 and support 60; Said machine barrel 10 is columniform, totally enclosed, a negative pressure space, is vertically mounted on the support 60.
The bottom of the said machine barrel 10 of a kind of particulate negative pressure of the utility model flour mill is pulverizing chamber 11; Crushing wheel 30 is housed in pulverizing chamber 11; Said crushing wheel 30 is the disk of rotation at a high speed, and this disk is fixed on the vertical hollow shaft 31, and the periphery of disk is equipped with removable movable cutter 32; Also be provided with fixed gear ring 13 on the inwall of this pulverizing chamber 11, have only very little gap between fixed gear ring 13 and the movable cutter 32 that flies to change.
The top of the said machine barrel 10 of a kind of particulate negative pressure of the utility model flour mill is grading rooms 12; Grading wheel 40 is housed in grading room 12; Said grading wheel 40 is another disk that rotates at a high speed; This disk is fixed on the vertical classification wheel shaft 41; Card is provided with fixed blade 42, also is provided with in this grading room 12 at a distance from grain baffle plate 14, and the pyramidal structure in grain baffle plate 14 and grading room forms labyrinth channel.
After particulate material to be pulverized is sent pulverizing chamber 11 through said pay-off 20 to from the bottom of said machine barrel 10; The crushing wheel 30 of rotation gets rid of granular material to periphery at a high speed; Under extruding between movable cutter 32 and the fixed gear ring 13, collision, rubbing action; For the first time be ground into the powder of dust shape and fine grained material and the compound of depositing;
Owing to suction tube 50 is constantly aspirating negative pressure, the compound that process is pulverized for the first time is inhaled into grading room 12 along the inwall of machine barrel 10, behind the entering grading room 12; Because at a distance from the labyrinth channel that the interior pyramidal structure of grain baffle plate 14 and grading room forms, the dust powder of light weight is siphoned away by suction tube 50, and the fine grained material is because the effect of gravity; Fall on the grading wheel 30,30 of grading wheels are with higher speed rotation, and powerful centrifugal force gets rid of the fine grained material to periphery again; Crash into pulverizing chamber 11; Be extruded again, collide, rub, and then once be inhaled into grading room 12, through the labyrinth channel classification; Go round and begin again, until becoming the dust powdery to be siphoned away by suction tube 50.
Described crushing wheel 30 of a kind of particulate negative pressure of the utility model flour mill and grading wheel 40 coaxial installations, counter-rotating drives with 2 frequency control motors respectively, can select different rotating speed and rotation direction separately according to material.
The said machine barrel of a kind of particulate negative pressure of the utility model flour mill 10 bottoms also are provided with air inlet 15; Be used to fix a silencer; When needs are pulverized wet feed or heat sensitive material; The air inlet 15 of a kind of particulate negative pressure of the utility model flour mill can external air-cooler, with pulverizing after the particulate material elder generation hardening by cooling to be pulverized again.
It is as shown in Figure 2,
One end of the said suction tube 50 of a kind of particulate negative pressure of the utility model flour mill is connected the top of said machine barrel 10, and the other end connects separation equipment 70 and air-introduced machine 80; The finished product powder that mixes with air is through separation equipment 70 and air separation, and the finished product powder is packed at this, and air is further purified the back and gets into air-introduced machine 80.
