Abstract
The invention discloses a hard sealed flapper door in a slide of a wedge-shaped groove. The hard sealed flapper door comprises a door frame and a flapper board. The hard sealed flapper door is characterized in that the door frame comprises an upper plate and a lower plate which are parallel with each other, a concentric coal-dropping channel is reserved from the upper plate to the lower plate, the upper plate and the lower plate are connected with each other through a near-end plate which is perpendicular to the two plates, the flapper board is inserted into the gap between the upper plate and the lower plate from the socket of the near-end plate so as to close or open the coal-dropping channel, two symmetrical side slopes are arranged on two sides of the upper plate and the lower plate along the inserting direction of the flapper board, and the side slopes coincide with a chamfer on the two sides of the flapper board inserted in the upper plate and the lower plate.
Description
Technical field
The present invention relates to a kind of loose unpacked material (based on coal) cutoff device that the industry such as coal-fired power plant, Coal Chemical Industry is conventional.
Background technique
The insertion plate door framework turned off for loose unpacked material (based on coal) in the former bucket system of industry such as existing coal-fired power plant, Coal Chemical Industry, its common structural type is square groove channel type or roller type, door body material mostly is 16Mn, plate material is common stainless steel, and driving mode divides three kinds: pneumatic type, electrodynamic type and manually operated type.But due to the defect of insertion plate door framework design, its conduit is at actual moving process easily long-pending coal, so often there is phenomenon that is stuck, that cannot close in plate, because insertion plate door cannot be closed, the accident causing equipment normally to run occurs often, there is obvious potential safety hazard source.
Summary of the invention
The object of this invention is to provide a kind of reasonable in design, the Novel plug board door that plate is stuck, cannot close phenomenon can not occur.
For reaching above object, the present invention takes following technological scheme to be achieved:
The hard sealing plug-in board door of a kind of wedge slot slideway, comprise door frame and plate, it is characterized in that, described door frame comprises the upper and lower clamping plate be parallel to each other, upper and lower clamping plate have concentric coal breakage passage, upper and lower clamping plate are connected by perpendicular proximal plate, and plate proximally plate socket inserts in the gap of upper and lower clamping plate, closes or open coal breakage passage; Upper and lower clamping plate are provided with sidepiece inclined-plane along the symmetrical both sides of plate direction of insertion, and this inclined-plane matches with the chamfering inserting centerboard both sides, upper and lower clamping plate gap; The far-end of described upper and lower clamping plate is provided with termination inclined-plane, and this inclined-plane matches with the chamfering inserting upper and lower clamping plate gap centerboard far-end.
In such scheme, the angle of inclination beta of described sidepiece inclined-plane, termination inclined-plane and horizontal plane is 30 °-60 °.Be generally 45 °.
Compared with conduit type or roller type insertion plate door, the advantage of wedge shape insertion plate door of the present invention is:
1, the wedge-shaped design of plate and doorframe sidepiece, first inclined-plane not easily long-pending coal, even if there is long-pending coal, long-pending coal also can be extruded by plate in running, ensures the unimpeded of plate, is put in place, can not produce the situation that bite fits badly by the disposable closedown of sidepiece tapered ramp.
2, plate chamfering and doorframe tapered ramp three directions match, and closing back door and frame seal tightly, and leak-down rate is all lower than 1%;
The present invention can be widely used in as the coal-fired power plant outlet of Coal Feeding in Circulating Fluidized Bed Furnace machine insertion plate door, recirculating fluidized bed slag dropping tube insertion plate door, run coal bin bottom insertion plate door, pulverized coal channel shutoff door etc.
Accompanying drawing explanation
Fig. 1-Fig. 3 is the three-view diagram of doorframe of the present invention; Wherein Fig. 3 is the plan view of Fig. 1, and Fig. 2 is that the A-A of Fig. 3 is to sectional view;
Fig. 4 is the planimetric map of plate of the present invention;
Fig. 5-Fig. 7 is the present invention's three kinds of different driving mode schematic diagram; Wherein Fig. 5 is pneumatic type; Fig. 6 is electrodynamic type; Fig. 7 is manually operated type.
Mark in Fig. 1-Fig. 7: 1, proximal plate; 2, punch holder; 3, die holder; 4, inclined-plane is stopped; 5, sidepiece inclined-plane; 6, coal falling hole; 7, flange mounting hole; 8, cylinder; 9, motor; 10, handwheel.
Embodiment
See Fig. 1 to Fig. 3, the hard sealing plug-in board door of a kind of wedge slot slideway, comprises door frame and plate, and door frame comprises the upper and lower clamping plate 2,3 be parallel to each other, and upper and lower clamping plate has concentric coal breakage passage 6, and coal breakage passage 6 periphery is provided with flange mounting hole 7.Upper and lower clamping plate are connected by perpendicular proximal plate 1, and plate proximally plate socket inserts in the gap of upper and lower clamping plate and coal breakage passage 6 can be closed.The symmetrical both sides of the upper and lower clamping plate of Fig. 2 are provided with sidepiece inclined-plane 5, and this inclined-plane matches with the chamfering (Fig. 4) inserting centerboard both sides, upper and lower clamping plate gap.The far-end of the upper and lower clamping plate of Fig. 1 is provided with and stops inclined-plane 4, and this inclined-plane matches with the chamfering (Fig. 4) inserting upper and lower clamping plate gap centerboard far-end.Sidepiece inclined-plane 5, the angle of inclination beta stopping inclined-plane 4 and horizontal plane can different according to the size of insertion plate door, design between 30 °-60 °.
The selection of plate, doorframe material: when system operating temperature is lower than 400 DEG C, can Martensitic Stain Less Steel be selected; Running temperature, when 400-600 DEG C, can select 304 stainless steels; Running temperature, when 600-800 DEG C, can select 321 stainless steels; Running temperature, when 800-950 DEG C, can select 309S or 310S stainless steel; Long to ensure the life-span that insertion plate door uses.
See Fig. 5-Fig. 7, the insertion plate door after the present invention improves, its driving mode still can adopt traditional pneumatic type, electrodynamic type or manually operated type.But reasonable due to project organization, ensure that door-plate not bite, the hard seal leakage rate of Nei-Nei is lower than 1%.The projected life of insertion plate door of the present invention is not less than 20 years; Cutoff device whole service life is greater than 10 years.
