Embodiment
The utility model is further illustrated below in conjunction with drawings and Examples.
Embodiment: the expansion chamber cleaned for rape described in the utility model, comprise the tubular sedimentation housing 2 of hollow, the taper air intake casing 1 of both ends open and be provided with grain outlet 32 connect grain housing 3, described taper air intake casing 1 is arranged on one end of tubular sedimentation housing 2 by the first flange 11, described tubular sedimentation housing 2 is laterally arranged on the top connecing grain housing 3, describedly connect the position that grain housing 3 contacts with tubular sedimentation housing 2 and be set to arc stamped sieve 23, characterized by further comprising and be provided with gather qi together mouth 51, the centrifugal blower 5 of power input shaft 52 and impeller 53, described impeller 53 is arranged on power input shaft 52, described gather qi together mouth 51 is connected with the other end of tubular sedimentation housing 2 by the second flange 21, the upper semisection of described tubular sedimentation housing 2 inwall is provided with Semicircular baffle 22, the bottom of described Semicircular baffle 22 tilts to gather qi together mouth 51 direction, described Semicircular baffle 22 is 3 ~ 5 ° with the scope of the inclination alpha of vertical direction.Described grain outlet 32 both sides are provided with slideway 31, are provided with the control arm-tie 4 for controlling grain outlet 32 aperture in described slideway 31.The diameter of described tubular sedimentation housing 2 is 355 ~ 365mm, length is 395 ~ 405mm.The radius of described Semicircular baffle 22 is 180 ~ 185mm, and the crooked radian of described arc stamped sieve 23 is 55 ° ~ 65 °, and the installation site of described Semicircular baffle 22 and the distance of taper air intake casing 1 entrance are 220 ~ 225mm.
The utility model adopts the rape of above-mentioned expansion chamber to clean method, comprises the following steps:
001, start centrifugal blower 5, power input shaft 52 impeller 53 is rotated, in expansion chamber air chamber, form negative pressure, and rape aspirate is entered by taper air intake casing 1 under negative-pressure air-flow effect;
002, calculate the volume of feeding material per second: record rape seed granule density average out to 1282kg/m
3, feeding 0.8kg/s per second, then the volume of feeding material per second is 6.24 × 10
5mm
3;
003, arrange Semicircular baffle 22 at distance 220 ~ 225mm place of taper air intake casing 1 entrance, the part between Semicircular baffle 22 and taper air intake casing 1 entrance forms the first air chamber, and now the first plenum interior volume averaging is 1.83 × 10
7mm
3be greater than the volume of feeding material per second, first plenum interior air velocity is lower, the axial flow of Semicircular baffle 22 pairs of enclosure interior produces longitudinal disturbance simultaneously, forces rape aspirate to pass through below Semicircular baffle 22, is tilted 3 ~ 5 ° the bottom of Semicircular baffle 22 to gather qi together mouth 51 direction, by horizontally set and coordinating of longitudinally arranging, both prevented the unexpected break-in of axial flow, promoted again rape aspirate rapid subsidence, and increased and effectively sieve distance to prevent blocking;
004, record seed and short stem floating velocity scope in aspirate and be respectively 7.4 ~ 9.4m/s and 6.3 ~ 11.2m/s, pod shell is respectively 2.4 ~ 3.2m/s and 1.1 ~ 3.2m/s with light assorted remaining floating velocity scope, short stem and seed sink, pod shell and light assorted more than be in material flow upper strata and siphon away by 5, the seed of sinking enters through arc stamped sieve 23 and connects grain housing 3, opens and controls arm-tie 4, closing control arm-tie 4 after taking-up seed after collecting the enough seed quantity needed;
005, the range of speeds of centrifugal blower 5 is adjusted to 1500r/min ~ 2000r/min, each feeding 0.8kg rape aspirate, wherein the content of seed is 0.1kg, clean rear collection at every turn and connect material in grain housing 3, weigh up the quality m of wherein seed, then expansion chamber can reduce entrainment loss rate Yj=m/0.1 × 100% of seed, draw at rotating speed to be that within the scope of 1500r/min ~ 2000r/min, expansion chamber can reduce seed entrainment loss rate 20% ~ 30%, there is certain actual application value.
After above-mentioned expansion chamber has been assembled, tubular sedimentation housing 2, taper air intake casing 1 and gather qi together mouth 51 are combined to form air chamber, Semicircular baffle 22 tilts 3 ~ 5 ° of settings, play cushioning effect, avoid the unexpected break-in of axial flow, reduce the head-on crash of rape seed and Semicircular baffle 22, reduce seed damage rate, stingy chamber inner space volume need be greater than the volume of feeding material per second to prevent blocking simultaneously.The short stem that quality is larger and seed sink, lighter pod shell and light assorted more than be in material flow upper strata and siphoned away by centrifugal blower 5, the seed sunk enters through arc stamped sieve 23 and connects grain housing 3, open after collecting the enough seed quantity needed and control arm-tie 4, after taking out seed, closing control arm-tie 4 waits for that next time collects, and decreases the entrainment loss of rape seed.
