Abstract
The utility model discloses a self-weight type buffer air lock comprising a coal drop pipe, wherein the coal drop pipe is arranged slantways; a buffer plate is arranged at the lower part in the coal drop pipe; the buffer plate is connected with the inner wall of the coal drop pipe through a hinge; the buffer plate is vertical to the horizontal plane under a free state; and the tail end of the buffer plate extends to the inner wall of the coal drop pipe. The self-weight type buffer air lock has an air locking function, has an obvious buffer speed-reducing effect on quick coal flow, reduces generation and overflow of coal dust, reduces the production cost, simplifies the process structure, and can greatly reduce the failure rate and the maintenance workload of equipment.
Description
Technical field
The utility model relates to a kind of charging gear, more particularly, is the dead-weight buffering flapper for coal spout.
Background technology
At present, the general structure of the buffering flapper of coal handling system is made up of parts such as flapper outer wall housing, equilibrate counterweight, bearing seat, rotating shaft and buffering baffle plates.The type buffering flapper is owing to dispose the clump weight of constant weight, and in use, under the power that swings back and forth the frequently effect, the balanced connecting rod of clump weight or balance fastening belt are easy to occur fracture; And because the equilibrate counterweight that increases has certain weight, make the swing bearing of bearing seat increase bigger load force, and the alerting ability that bearing rotates is subjected to certain influence, and the problem of jam appears in cushioning fender easily.The type buffering flapper manufacturing cost is higher, maintenance is big, influences production efficiency.
The utility model content
The utility model aims to provide a kind of self gravitation of internal damping baffle plate that only relies on can realize that just the dead-weight of balanced seal lock gas and buffering material function cushions flapper.
The technical solution of the utility model is: a kind of dead-weight buffering flapper, comprise coal spout, wherein, described coal spout is inclined to set, be provided with dash plate below in coal spout, for hinge is connected, vertical with horizontal surface during described dash plate free state, the end of this dash plate extends on the coal spout inwall between dash plate and the coal spout inwall.
Above-mentioned a kind of dead-weight buffering flapper, be that a rotating shaft is passed the tube wall of coal spout and is installed on the coal spout by two sealing axle sleeves for hinge is connected between described dash plate and the coal spout inwall, link together by bearing between described dash plate and the rotating shaft.
Above-mentioned a kind of dead-weight buffering flapper is equipped with indicator stem at an end of rotating shaft.
Above-mentioned a kind of dead-weight buffering flapper, the angle that described coal spout and horizontal surface tilt is less than 80 degree.
The utility model adopts above-mentioned structure, with the structure that the internal damping baffle design of flapper becomes one-sided baffle plate, vertical hanging to arrange, cushioning fender when natural vertical hanging, its terminal inwall with coal spout offsets, and realizes the function of balanced seal lock gas; When material falls on the cushioning fender from coal spout, realize the function of buffering material, reduce the generation of coal dust and overflow; Dash plate is under the impact force action of material, open certain opening, make material from aperture slots, fall to the outlet of below coal spout, the size of dehiscing of dash plate changes with the mutual action of the vertical gravity of the impulsive force of material and dash plate self, dash plate does not still constantly keep the state of dense block gas in having the zone of material stream passed, this structure has been removed equilibrate counterweight, reach the technical purpose that reduces manufacturing cost and simplify process structure, realized the function of balanced seal lock gas and buffering material; And since the minimizing of the overall supported weight of bearing, the effect that has realized improving the flapper reliability of operation greatly and reduced the repair and maintenance work capacity; End in rotating shaft is equipped with indicator stem, and indicator stem can intuitively indicate the concrete aperture position of internal damping baffle plate and the running state of flapper, so that the staff adjusts.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is concrete enforcement scheme drawing of the present utility model;
Fig. 3 is the A-A cross-sectional view of Fig. 1.
Among the figure: 1 is coal spout, and 11 are rotating shaft, and 12 is sealing axle sleeve, and 2 is dash plate, and 3 is indicator stem.
The specific embodiment
As shown in Figure 1 to Figure 3, a kind of dead-weight buffering flapper, comprise coal spout 1, coal spout 1 is inclined to set, be provided with dash plate 2 below in coal spout 1, dash plate 2 bearing surfaces are equipped with the thick high-chromium wear-resistant liner plate of 25mm, are connected for hinge between dash plate 2 and coal spout 1 inwall, vertical with horizontal surface during dash plate 2 free states, the end of this dash plate 2 extends on coal spout 1 inwall; Be that a rotating shaft 11 is passed the tube wall of coal spout 1 and is installed on the coal spout 1 by two sealing axle sleeves 12 for hinge is connected between dash plate 2 and coal spout 1 inwall, link together by bearing between described dash plate 2 and the rotating shaft 11; End in rotating shaft 11 is equipped with indicator stem 3; Coal spout 1 is spent less than 80 with the angle that horizontal surface tilts.
The utility model in the specific implementation, when coal falls from coal spout 1 with certain speed, directly impact on dash plate 2, dash plate 2 is under the impact force action of material, open certain opening, make material from aperture slots, fall to the outlet of below coal spout 1, when dash plate 2 does not have the load-bearing thing, rely on the gravity of self to reset.
