Description
Technical field
The utility model relates to a kind of grain impurity removing equipment, particularly relates to a kind of to removing assorted greatly, thin assorted, the more effective drum sieve combination of light impurity grain cleaning winnowing machine in the grain material.
Background technology
At present, the combined equipment that is used for the impurity cleaning that domestic grain depot is commonly used has following several type:
(1) the cleaning sieve that combines with cycle winnowing device of vibratory sieve
Cycle winnowing device is made up of parts such as the air channel of oscillating feeder, air draught road, adjustable thickness, gravity separator, impurity-discharing screw body, radial fan, return air duct, segmentation valve.
Technical process: the raw grain material is sent into this machine by oscillating feeder, blower fan is contained in gravity separator two upper lateral parts, during material process bottom, air draught road, air-flow upwards takes the light impurity in the grain material to and carries out sedimentation in the gravity separator, then by the output of impurity-discharing screw body, again outside wind stopping device discharge machine.Radial fan is got back to the air draught road from the wind that axial sucking-off discharges behind the impurity by return air duct, and is distributed on the overall with in air channel.Air circulation is used.
(2) electronic mold blower
Generally the hand-rail type windmill of use was similar in the rural area to the past for the operation principle of electronic mold blower, just made hand part into Motor Drive, after during work the light impurity in the grain being blown out, sedimentation aloft or be equipped with cyclone dust collectors again and collect.
(3) open-type grain winnowing machine
It with reference to application number 200520046107.6 Chinese patent " open-type novel foodstuff winnowing machine ", its operation principle is that material flow is removed mixing greatly in the grain through thin bamboo strip formula fence, material process twice selection by winnowing can effectively be removed the light impurity in the grain, and the row of making reached the regulation of national environmental protection index after dust laden air was then collected by binary cyclone dust collector to the air quality of atmosphere.
(4) drum sieve combination grain winnowing machine
Drum sieve combination grain winnowing machine is the cylinder receiving sieve to be combined with open-type novel foodstuff winnowing machine form drum sieve combination grain winnowing machine, replace removing big assorted structure with thin bamboo strip formula fence in the former open-type grain winnowing machine, can solve the cleaning of big assorted, thin assorted, the light impurity in the raw grain, but because the drum sieve charging is to enter the screen drum inboard by chute, materials flow is " ∠ " type backward feed, enter the back by the screen of compass screen surface screen drum, grain falls into discharging opening by sieve aperture, and big assorted moving from inside to outside along the spiral deflector chute falls into discharging opening.Shortcoming is to select for use with the adaptive cylinder receiving sieve profile of winnowing machine greatlyyer, and the easy putty in charging chute place causes material fully not enter and carries out screen in the screen drum, so cleaning effect is not very good.
Sum up above-mentioned domestic product of the same type, mainly there are following problem in the technology and the device of light impurities such as big assorted in cleaning, thin assorted, shrivelled kernel and dust:
(1), the advantage of cycle winnowing device be take up room little, need not to be equipped with the wind outside net, do not need air channel or independent dust arrester, but say it is to belong to the enclosed working method from its operation principle, simultaneously because its gravity separator is little, the every circulation primary of dust laden air always has the part light impurity to be brought back to the starting point place of air draught, therefore removes light assorted effect than open-type difference.
(2), the environment dust pollution was more serious when electronic mold blower was worked, and is not high to the separating effect of light impurity.
(3), open-type grain winnowing machine big assorted undesirable by thin bamboo strip formula fence cleaning effect, need artificial regularly cleaning, easily cause untimely cleaning impurity and putty.
(4), drum sieve and open-type combination winnowing machine combine and then causes the material charging not smooth easily, flash or putty, or bigger for guaranteeing to use the equipment profile of matching.
