Description
Technical field
The present invention relates to Grain Logistics, relate in particular to a kind of Bulk Grain automobile unloading operation dust catching device.
Background technology
During Bulk Grain automobile handling grain, can produce a large amount of airborne dusts, as these airborne dusts, not control well and can cause environmental pollution, affect worker healthy.At present, the method that flour dust overflow is controlled in Bulk Grain automobile unloading operation is, on lower grain hole, suspended hood is set, and existing suspended hood as shown in Figure 1, is comprised of aspiration channel 1, linkage section 2, front wind screen 3, left side deep bead and right side deep bead etc.There is following problem in the dust exhaust apparatus of this structure: 1) air draught effect exists dead band, when main cause is Bulk Grain automobile unloading operation because the grain that moves downward is by the spatial separation Cheng Liaozhu airborne dust district 11He Fu airborne dust district 12 on top, lower grain hole, the dust in air draught Dui Zhu airborne dust district 11 has the ability of catching of flutterring preferably, and due to the iris action of the grain layer moving downward to air draught formation, the capability of influence of the dust in air draught Dui Fu airborne dust district 12 is less, secondary airborne dust district 12 excessive dust can not effectively be flutterred and be caught, cause unloading speed speed, the pick-up performance of unloading more than flow vector and when few is not identical, even if it is also not obvious to strengthen the effect in suction air volume Dui Fu airborne dust district 12, 2) in order to meet the turnover of Bulk Grain automobile and unloading effect, suspended hood generally all designs highlyer, the air quantity needing is large, the air draught effect on top is stronger, a little less than the air draught effect of bottom, after Bulk Grain automobile unloads and pays the grain tax and leave, the excessive dust that the grain in hole produces when flowing downward out hole is difficult to flutter to be grasped.Therefore existing Bulk Grain automobile unloading dust exhaust apparatus exists energy consumption high, and the effect of controlling flour dust overflow in the dynamic process of unloading operation is unstable, and pick-up performance is undesirable.
Summary of the invention
The object of this invention is to provide a kind of Bulk Grain automobile unloading dust exhaust apparatus, it can effectively flutter the airborne dust producing while catching the unloading of Bulk Grain automobile.
In order to achieve the above object, the present invention is by the following technical solutions: a kind of efficient Bulk Grain automobile unloading dust exhaust apparatus comprises aspiration channel, linkage section, rear wind-break panels, left side deep bead, right side deep bead, it is characterized in that it also comprises top board, internal air baffle, transverse air suction pipe and transverse air suction mouth; Internal air baffle is arranged in below top board, forms a vertical air suction passage with left and right side deep bead and rear wind-break panels, and this vertical air suction passage is by connecting portion and aspiration channel UNICOM; On transverse air suction pipe, have inlet scoop.
The width of described internal air baffle is half of rear wind-break panels width, or the width of internal air baffle is greater than rear wind-break panels width half.Middle part or the middle and lower part of the suction inlet that can make vertical air suction passage in main airborne dust district.
Described transverse air suction pipe is prolate strip, pastes ground configuration on one side of lower grain hole turnover Bulk Grain automobile; The face down one side in grain hole of transverse air suction pipe has strip inlet scoop, and the length of inlet scoop is identical with the width in lower grain hole, and this inlet scoop is provided with equal style grid or perforated panel, one side make it along the uniform air draught effect that has in lower grain hole, elimination air draught dead band.
The one side of inlet scoop of leaning on above of described transverse air suction pipe is provided with elasticity dust board.
Described elasticity dust board is rubber or polyurethane material plate, and its end face terrain clearance is identical with Bulk Grain bottom of car terrain clearance or slightly higher.
Principle and the feature of the efficient Bulk Grain automobile of the present invention unloading operation dust exhaust apparatus be, Bulk Grain automobile unloading operation has the reason of several aspects to produce dust to leak, the one, and the grain unloading will occupy the certain space in lower grain hole, can make the air in lower grain hole outwards flow; The 2nd, grain hole under can flowing to certain acceleration under the effect of gravity while unloading under grain, the dust in grain can be separated with grain under the effect of air, under the effect of moving air, forms airborne dust; The 3rd, the grain unloading produces and impacts and formation airborne dust with the grain in certain speed and lower grain hole or lower grain hole.
The continuous grain stream being removed on the top in lower grain hole during Bulk Grain automobile unloading operation has formed the airborne dust district of major and minor two separations, and the airborne dust direction in major and minor airborne dust district is different.For Liang Ge airborne dust district separately the direction of flour dust overflow in major and minor Liang Ge airborne dust district, inlet scoop is set respectively, along the direction following current of flour dust overflow, flutter and catch airborne dust.The middle and lower part in Zhu airborne dust district arranges inlet scoop, and the air in Shi Zhu airborne dust district, as far as possible along grain flow path direction, is realized the object of efficient dust suction; Fu airborne dust district is close to the ground, on one side of lower grain hole turnover Bulk Grain automobile, transverse air suction mouth is set, and along dust, to the excessive direction following current of bottom of car, flutters and catches airborne dust.
The invention has the beneficial effects as follows, the air flow field on top, Zhu airborne dust district is along grain flow path direction, can reduce in grain stream part dust separated with grain, reduces flour dust overflow amount, is conducive to reduce the dustiness in aspiration channel.Liang Ge airborne dust district arranges respectively inlet scoop along the direction of flour dust overflow, flutters that to catch the efficiency of airborne dust high, controls dust Air Quantity Required relatively little, controls the effective of flour dust overflow, and it is little that inlet scoop following current arranges resistance, and energy consumption also can reduce.
