Detailed description of the invention
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment.
Referring to Fig. 1 to Fig. 3, Anti Plugging Bunker in the present embodiment comprises coal chamber body 1, bulkhead 2, No. two bulkheads 3, coal unloading tube 4, No. two coal unloading tubes 5, air bubble and hertz oscilltors, wherein, air bubble and hertz oscilltor are installed in coal chamber body 1, the quantity of air bubble and hertz oscilltor can arrange according to actual needs, under normal circumstances, the quantity of air bubble and hertz oscilltor is more than two.
A bulkhead 2 and No. two bulkheads 3 in the present embodiment are up big and down small truncated cone-shaped structure, a bulkhead 2 and No. two bulkheads 3 are reverse frustoconic structure, that is to say that the top of a bulkhead 2 is greater than the bottom of a bulkhead 2, the top of No. two bulkheads 3 is greater than the bottom of No. two bulkheads 3.
In the present embodiment, the top of a bulkhead 2 is arranged on the bottom of coal chamber body 1, rounding off between this bulkhead 2 and coal chamber body 1, and the base diameter of a bulkhead 2 is 930-940mm, the base diameter of this bulkhead 2 is preferably 934mm.The base diameter of the diameter of a coal unloading tube 4 and a bulkhead 2 is equal, and the height of this coal unloading tube 4 is 100-200mm, and the height of a coal unloading tube 4 is preferably 150mm.The upper end of a coal unloading tube 4 is connected to the bottom of a bulkhead 2, the axis of the axis of a coal unloading tube 4 and a bulkhead 2 is all vertical shape structure, the axis of the axis of this coal unloading tube 4 and a bulkhead 2 is overlapping, angle β between bulkhead 2 and horizontal surface is 66-72 degree, and angle β is preferably 71 degree.
In the present embodiment, the top of No. two bulkheads 3 is arranged on the bottom of coal chamber body 1, rounding off between these No. two bulkheads 3 and coal chamber body 1, and the base diameter of No. two bulkheads 3 is 930-940mm, the base diameter of these No. two bulkheads 3 is preferably 934mm.The base diameter of the diameter of No. two coal unloading tubes 5 and No. two bulkheads 3 is equal, and the height of these No. two coal unloading tubes 5 is 100-200mm, and the height of No. two coal unloading tubes 5 is preferably 150mm.The upper end of No. two coal unloading tubes 5 is connected to the bottom of No. two bulkheads 3, the axis of the axis of No. two coal unloading tubes 5 and No. two bulkheads 3 is all vertical shape structure, the axis of the axis of these No. two coal unloading tubes 5 and No. two bulkheads 3 is overlapping, angle η between No. two bulkheads 3 and horizontal surface is 66-72 degree, and angle η is preferably 71 degree.
Raw coal mainly leans on the gravity of self along bulkhead toward current downflow in coal bunker, mobile power depends on the friction force with raw coal and bulkhead, and friction force and bulkhead angle relation in direct ratio under normal circumstances, therefore, the angle of bulkhead and horizontal surface is larger, and ature of coal flowing power is stronger.Under normal circumstances, feeder lock gate hatch absolute altitude designs according to explosion--proof regulations, the straight length of design is longer, but this kind of design is not inconsistent with scene is actual conventionally, the one, cause the too high and execute-in-place inconvenience of lock gate hatch absolute altitude, the 2nd, straight length is long forms extruding to material itself, and friction force increases and causes chute blockage.
The utility model can further be optimized, and as improved coal breakage height, coal bunker coal dropping port (coal lock gate hatch) absolute altitude is brought up to 14.80m; Can cancel lock gate hatch top straight length; The position of tapping point in the middle of can improving, increases bulkhead angle, breaks through former coal reserves restriction in 8 hours; Feeder can be changed into square entrance, increase area.
In addition, it should be noted that, the specific embodiment described in this specification sheets, shape, institute's title of being named etc. of its parts and components can be different, and the above content described in this specification sheets is only to the explanation of the utility model structure example.All equivalence variation or simple change of doing according to described structure, feature and the principle of the utility model patent design, are included in the protection domain of the utility model patent.The utility model person of ordinary skill in the field can make various amendments or supplements or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
