The spray wind section of main shaft 202 is located at feed side.
The air draught section of main shaft 202 is located at exit side.
The end perforate 210 of main shaft 202 feed sides is connected UNICOM with spray wind blower fan 103.
The spray wind section of main shaft 202 is provided with spray wind hole, spray wind hole on the main shaft spray wind section is provided with multirow vertically, the spray wind hole of present embodiment is provided with triplex row, promptly distribute along circumference 120 degree, shown in Fig. 2,3, the spray wind hole circle heart on the adjacent lines is not in same periphery, and spray wind hole shifts to install, spray wind hole 301,302 in the present embodiment as shown in Figure 3 in same periphery, spray wind hole 303 is arranged with 301,302 dislocation of spray wind hole; Spray wind section is divided into spray wind leading portion and spray wind stage casing, and promptly the main shaft on bearing rib 205 right sides is spray wind leading portion, and the main shaft in bearing rib 205 left sides is spray wind back segment.The gross area in spray wind hole is greater than the gross area in spray wind hole on the spray wind leading portion on the main shaft wall in spray wind stage casing.
The air draught section of main shaft 202 is provided with wind inlet, and main shaft 202 air draught sections (being that the air draught section is the main shaft rear) are on the right side of bearing rib 207.Wind inlet comprises the wind inlet 310 of 204 times correspondences of sand roller and stretches out the wind inlet 320 of the outer main shaft 202 air draught sections of frame.Present embodiment wind inlet 310 is provided with triplex row, promptly distributes along circumference 120 degree, realizes the dislocation layout.
Shown in Fig. 4,5, wind inlet 320 is provided with four lines vertically, and the four lines wind inlet is divided into two groups, and two wind inlets of each group are in diametric(al) setting (symmetry); Shift to install between two groups.
As shown in Figure 1, main shaft exit side bracing frame 111 supports by bearing 112 and main shaft 202 air draught sections.Bracing frame is provided with air intake inlet scoop 113, and air intake inlet scoop 113 communicates with wind inlet 320 on the main shaft wall; 113 places, air intake inlet scoop on the bracing frame establish air intake inlet scoop aperture adjustable plate 108.Aperture adjustable plate 108 adopts the shutter board of circular arc.The bearing location of being connected with of main shaft exit side bracing frame 111 cover 114, and bearing is located and covered 114 tegmental wall and offer air vent 115, and air vent 115 communicates with main shaft exit side end perforate 211.
The gusset that sand roller 204 is connected with main shaft at the sand roll shaft to the center, with sand roller inner chamber be isolated into preceding, in, three air chambers of tail.Be respectively leading portion malleation air chamber, stage casing malleation air chamber and tail end negative pressure chamber.
In rice mill when work: circular rice huller screen inwall and sand roller circumferential outer surface be apart from being called " depositing gas " for δ, and the chamber that is formed vertically by radially " deposit gas " δ and rice huller screen inwall and sand roller outer surface becomes " whitening chamber "; Brown rice is entered by charging aperture, send into " whitening chamber " along circumference and axially-movable by spiral propeller 203, the grain of rice contacts with the sand roller to grind and cuts the chaff cortex in " whitening chamber ", and the grain of rice promotes lower edge journey stone roller at spiral propeller 203 and cuts, by closing outside the wind discharging opening 109 eliminating machines; Inhale outside under the effect of chaff wind net, grind the chaff powder that removes and inhale chaff wind net through inhaling 110 suctions of chaff bucket by rice huller screen 106 discharges " whitening chamber ".
Usually rice mill is joined outward and is inhaled chaff wind net and provide air draught more than the blast 1500Pa to rice mill, inserts and inhales chaff bucket 110.Main shaft two ends air intake, one end is a forced draft, the other end is the negative pressure air draught, be provided with in the main shaft every wind locking head 206 the axle endoporus is divided into two different pressure an actor's rendering of an operatic tune of malleation and negative pressure, the space that sand roller inwall and spindle outer wall constitute is called " air chamber ", and the malleation wind regime is provided by spray wind blower fan 103, enter the main shaft axis hole from feed end, send into head section, stage casing " air chamber " by the main shaft radial hole along journey, form head section malleation air chamber, stage casing malleation air chamber, spray into whitening chamber; The other end of main shaft communicates with air, under the suction function that the exogenous wind net provides, suck the rear whitening chamber by main shaft axis hole, rear negative pressure " air chamber ", under the effect of exogenous wind net negative pressure air draught, when the malleation wind of one end and the negative pressure wind of the other end enter whitening chamber by sand roller air vent, preceding, in, the windage of rear is autobalance (head section resistance h
Head=stage casing resistance h
In=rear resistance h
Tail).Because the rear whitening chamber communicates with air, the discharging bearing block is provided with air inlet through hollow shaft has increased incoming air area, and radially air intake has shortened the blast pipe segment length and reduced the air intake resistance, makes negative pressure air intake pipeline section resistance little; And stage casing and head section blast pipe segment length, the air intake resistance is big, adopts the supercharging air-supply to overcome the air intake resistance, and whitening chamber head section resistance, stage casing resistance and rear resistance are equated.
