Abstract
The utility model relates to a material conveyance device, specifically to an air chute. The air chute comprises an upper slot, a lower slot and a material cut-off device, wherein the upper slot is a material slot, the lower slot is an air slot, a ventilating layer is arranged between the upper slot and the lower slot, the material cut-off device comprises a damper, a damper supporting frame and an air cylinder, the damper supporting frame is arranged at the upper end of the upper slot, the damper is movably arranged in the damper supporting frame up and down, and the air cylinder is used for driving the damper to move up and down to realize the opening and the closing of the upper slot; and a transverse through slot is arranged in the ventilating layer which is arranged on a same vertical plane with the damper, a rubber layer covers the upper end surface of the through slot, and a baffle is arranged on the lower end surface of the through slot. The air chute disclosed by the utility model has two seal, namely the rubber layer and the baffle, ensures that the leakage rate of products at a cut-off state is lower than 1% by utilizing the combination of flexible seal and rigid seal, and has a simple structure and low cost.
Description
Technical field
A kind of material transmission apparatus that the utility model relates to is specially a kind of air flume.
Background technology
Domestic material cut-off equipment adopts rigid hermetically-sealed construction at present, because the air permeable effect of air-permeable layer, granular material is blocked in fluidised situation, and air continues to blow to air-permeable layer, produces the gap between air-permeable layer and the overhead gage, and it is serious to cause material to be revealed.
Summary of the invention
The purpose of this utility model provides the material cut-off equipment that a kind of air flume, described air flume are provided with favorable sealing property, and described material throttling device is simple in structure, cheap.
The technical scheme that realizes above-mentioned purpose is: a kind of air flume, comprise groove, following groove and material cut-off equipment, described upward groove is hopper, following groove is air drain, is provided with air-permeable layer between last groove and following groove, and described material cut-off equipment comprises flashboard, flashboard support frame and cylinder, described flashboard support frame places the upper end of groove, described flashboard is moving up and down to be installed in the flashboard support frame, and described cylinder is used for driving flashboard and moves up and down the opening and closing of groove in the realization; It is characterized in that: be provided with horizontal groove in the air-permeable layer with the same vertical plane surface of flashboard, the upper surface of groove is coated with rubber layer, and the lower surface of groove is provided with baffle plate.
The beneficial effects of the utility model are: the utlity model has rubber layer and baffle plate two seals, adopt flexible sealing to combine with positiver sealing, guaranteed that product leakage rate under off condition is lower than 1%; And the utility model is simple in structure, and cost is lower.
Optimally, above described air-permeable layer, be provided with breaker plate.Can push down air-permeable layer by breaker plate, prevent that air-permeable layer is at the effect lower convexity of wind-force.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model;
Fig. 3 is A portion enlarged drawing among Fig. 2;
Fig. 4 is the structural representation of breaker plate.
The specific embodiment
Shown in Fig. 1-4, comprise groove 1, following groove 2 and material cut-off equipment 3, described upward groove 1 is hopper, and following groove 2 is air drain, is provided with air-permeable layer 7 between last groove 1 and following groove 2, and the top of air-permeable layer 7 also is provided with breaker plate 10.
Material cut-off equipment 3 comprises flashboard 4, flashboard support frame 5 and cylinder 6, described flashboard support frame 5 places the upper end of groove 1, described flashboard 4 moving up and down being installed in the flashboard support frame 5, described cylinder 6 are used for driving flashboard 4 and move up and down the opening and closing of groove 1 in the realization.
Be provided with horizontal groove in the air-permeable layer 7 with flashboard 4 same vertical plane surfacies, the upper surface of groove is coated with rubber layer 8, and the lower surface of groove is provided with baffle plate 9.
Principle of work of the present utility model: material is in last groove 1 course of conveying, and flashboard 4 in opened condition.When not needing convey materials, cylinder 6 promotes flashboard 4 and moves downwards, and when compressing rubber layer 8 extended to baffle plate 9, cylinder was out of service.
Claims (2)
