Description
Technical field
The present invention relates to cereal processing machine tool field, and in particular to a kind of vertical rice whitening machine.
Background technology
Rice mill is a kind of common cereal processing machine tool, and it the mode such as exchanges views by the crust of brown rice by being ground or extruding
Grind de- so as to obtain rice and chaff powder, then separated chaff powder and rice by sieve aperture or selection by winnowing mode.Rice mill is according to driving
The installation form of main shaft can be divided into vertical rice whitening machine and horizontal rice whitening machine.
Vertical rice whitening machine is generally provided with chaff powder collecting chamber below husk rice room, after chaff powder falls into collecting chamber, in gravity or
Under the mechanical forces such as scraper plate, chaff powder is discharged.When chaff powder is scraped by scraper plate, because the discharge effect of chaff powder can be collected in chaff powder
Room produces small negative pressure, and this small negative pressure is downwardly into chaff powder collecting chamber for chaff powder in husk rice room has certain promotion to make
With, but because negative pressure is very small, therefore it is produced to chaff powder sucking-off effect also very little, cause the chaff powder in husk rice room can not be timely
Suction out, have influence on husk rice efficiency, also increase bran-containing quantity in rice.
In order to which the chaff powder in husk rice room is suctioned out in time, so that not interfering with husk rice efficiency, existing rice mill generally configures
Special induced-draught fan and air-suction duct.Such as Chinese patent literature CN204710413U discloses a kind of vertical sand-roll rice milling machine and sent

Gap 73.
Mounting structure 3 is provided with least one row's chaff for chaff powder to be discharged corresponding to the position of fan blade component 7
Mouth 5.The side wall of the corresponding position of fan blade component 7 of mounting structure 3 is referred to as blower fan shell side wall 33, the side of the corresponding position of husk rice room 2
Wall is referred to as husk rice room side wall 31.Specifically, the side wall between bottom plate 32 and deflector 9 is blower fan shell side wall 33, deflector 9 and top
Side wall between plate 34 is husk rice room side wall 31.In the present embodiment, the vertical rice whitening machine includes row's chaff mouth 5, row's chaff mouth 5
It is arranged at the position that blower fan shell side wall 33 corresponds to the neighboring of fan blade component 7.
The operation principle of the vertical rice whitening machine is：
Deflector 9, bottom plate 32 and blower fan shell side wall 33 form Blower Housing structure, fan blade component 7 and the wind of surrounding
Casing body structure composition centrifugal fan structure.The fan inlet 8 at the middle part of deflector 9 is the " air inlet for being somebody's turn to do " centrifugal blower "
Mouthful ", row's chaff mouth 5 is " gas outlet " for being somebody's turn to do " centrifugal blower ".During fan blade component 7 rotates with drive shaft 6, " centrifugation
Air centrifugalization in blower fan " is got rid of to edge and discharged by " gas outlet ", is somebody's turn to do " air inlet " place of " centrifugal blower "
Obvious negative pressure state (relating to parameters such as the diameter of the vacuum magnitude and fan blade component 7, shape) is presented so that positioned at leading
The top of flowing plate 9 and husk rice room 2 form sufficiently large negative pressure, and in the outside of charging aperture 1, the air in atmospheric pressure state is made in this negative pressure
Husk rice room 2 is inhaled under, and " air inlet " of " centrifugal blower " is flowed into further across the first gap 4, finally from " centrifugation wind
" gas outlet " discharge of machine ", forms air flow, airflow direction is as shown in the direction of arrow in figure.Husk rice room 2 is ground the chaff powder and existed
Under this air flow rolling action promotes, the first gap 4, fan inlet 8 can be rapidly passed through, into fan blade component 7,
Finally discharged from row's chaff mouth 5.
The technical program forms negative-pressure air-suction effect in the case where deflector 9 and fan blade component 7 act on, to husk rice room 2, can
To effectively facilitate chaff powder discharge, and then improve husk rice effect.Also, fan blade component 7 is fixedly installed on same with sand piece 10
Drive shaft 6, rotated under the drive of the drive shaft 6 around the axis of drive shaft 6, simplify equipment overall structure, reduce equipment system
Make cost and maintenance cost.
As another implementation, deflector 9 and bottom plate 32 are saved in vertical rice whitening machine selection.It arranges chaff mouth 5
The lower opening of mounting structure 3 (the former position of bottom plate 32).So as to be formed since the charging aperture 1, husk rice room 2, the first gap 4 are flowed through,
Until the air-flow of fan blade component.Its operation principle and above-mentioned identical, identical purpose can be achieved, do not repeating.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among changing still in the protection domain of the invention.
