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 the industries such as coal-fired power plant, Coal Chemical Industry a kind of loose unpacked material (take coal as main) cutoff device commonly used.
Background technique
Be used for the insertion plate door framework that loose unpacked material (take coal as main) turn-offs in the former coal bunker of industry such as existing coal-fired power plant, Coal Chemical Industry system, its common structural type is square groove road type or roller type, door body material mostly is 16Mn, the plate material is common stainless steel, and driving mode is divided three kinds: pneumatic type, electrodynamic type and manually operated type.But due to the defective of insertion plate door framework design, its conduit easily amasss coal in actual moving process, so phenomenon stuck, that can't close that plate often occurs, because insertion plate door can't be closed, the accident that causes equipment normally to move occurs often, has apparent in view potential safety hazard source.
Summary of the invention
The purpose of this invention is to provide a kind of reasonable in design, the Novel plug board door that plate is stuck, can't close phenomenon can not occur.
For reaching above purpose, 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 that are parallel to each other, have concentric coal breakage passage on upper and lower clamping plate, upper and lower clamping plate are connected by perpendicular proximal plate, and plate inserts the gap of upper and lower clamping plate from the proximal plate socket, closes or open the coal breakage passage; Upper and lower clamping plate are provided with the sidepiece inclined-plane along the symmetrical both sides of inserting board Inbound, this inclined-plane matches with the chamfering of inserting centerboard both sides, upper and lower clamping plate gap.
In such scheme, the far-end of described upper and lower clamping plate is provided with the termination inclined-plane, and this inclined-plane matches with the chamfering of inserting upper and lower clamping plate gaps centerboard far-end.
The angle of inclination beta of described sidepiece inclined-plane, termination inclined-plane and horizontal plane is 30 °-60 °.Be generally 45 °.
Compare 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, at first the inclined-plane is difficult for long-pending coal, even long-pending coal is arranged, plate also can be extruded amassing coal in running, guarantees the unimpeded of plate, puts in place by disposable the closing in sidepiece wedge shape inclined-plane, can not produce the situation that bite fits badly.
2, plate chamfering and doorframe wedge shape three, inclined-plane direction match, and closing back door and frame sealing are tight, and leak-down rate is all lower than 1%;
The present invention can be widely used in as coal-fired power plant Coal Feeding in Circulating Fluidized Bed Furnace machine outlet 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.

Embodiment
Referring to 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 that are parallel to each other, and has concentric coal breakage passage 6 on upper and lower clamping plate, and coal breakage passage 6 peripheries are provided with flange mounting hole 7.Upper and lower clamping plate are connected by perpendicular proximal plate 1, and plate can be closed coal breakage passage 6 from the gap of the upper and lower clamping plate of proximal plate socket insertion.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) of 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) of inserting upper and lower clamping plate gaps centerboard far-end.Sidepiece inclined-plane 5, stop that the angle of inclination beta of inclined-plane 4 and horizontal plane can be according to the size of insertion plate door different, design between 30 °-60 °.
The selection of plate, doorframe material: system's running temperature can be selected Martensitic Stain Less Steel during lower than 400 ℃; Running temperature can be selected 304 stainless steels in the time of 400-600 ℃; Running temperature can be selected 321 stainless steels in the time of 600-800 ℃; Running temperature can be selected 309S or 310S stainless steel in the time of 800-950 ℃; Long with the life-span that guarantees the insertion plate door use.
Referring to 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 due to project organization rationally, guaranteed not bite of door-plate, the hard seal leakage rate of Nei-Nei is lower than 1%.Be not less than 20 years the projected life of insertion plate door of the present invention; The cutoff device whole service life was greater than 10 years.
