The dry coke quenching intermediate chute manhole cover of above-mentioned energy fast assembling-disassembling, the plate of described upper cover lower surface is made up of three ply board face, three ply board face is vertically superposed to be connected as one, the length in inner plating face is the longest, the length in intermediate plate face and lamina rara externa face gradually reduces, and the step of the inwall in lower aperture is three layers step, and the upper surface of three layers step is relative with the lower surface in the three ply board face of upper cover plate respectively, sealing ring is placed on the upper surface of intermediate step, and the lower surface in intermediate plate face is in close contact with sealing ring.
The dry coke quenching intermediate chute manhole cover of above-mentioned energy fast assembling-disassembling, there is inclination angle the lower surface in the inner plating face of described upper cover plate, intermediate plate face and lamina rara externa face.
The dry coke quenching intermediate chute manhole cover of above-mentioned energy fast assembling-disassembling, described sealing ring is high temperature resistant asbestos board, or high temperature resistant asbestos cord, or high temperature resistant asbestos pad.
The beneficial effects of the utility model are:
Existing dry coke quenching intermediate chute manhole cover is transformed by this utility model, does not retain upper flange, manhole cover changes into board plug type upper cover, former lower flange changes aperture under staged into, upper cover lower surface periphery increases plate, adopts high temperature resistant asbestos board to do encapsulant, to strengthen the sealing of manhole cover.Securing member between upper cover and lower aperture adopts opening fixed block to fix, with bolt, the mode that seat combines, dismount very convenient fast.The present invention has simple in construction, be easy to dismounting, maintenance time is short, good seal performance, recyclegas are not easily overflowed advantage, it is easy to the troubleshooting of rotary seal valve, effectively alleviate the impact on dry coke quenching and generating of the rotary seal valve jam, enterprise is had significant economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the top view of upper cover；
Fig. 3 is lower aperture top view.
In figure, labelling is as follows: upper cover 1, lower aperture 2, plate 3, step 4, sealing ring 5, fixed block 6, opening 7, bolt fixing seat 8, screw 9, inner plating face 10, intermediate plate face 11, lamina rara externa face 12, bolt 13.
Detailed description of the invention
This utility model is made up of upper cover 1 and lower aperture 2, instead of original upper flange and lower flange.Upper cover 1 and lower aperture 2 can be circular, it is also possible to for rectangle, determine according to people's hole shape of intermediate chute, and upper cover 1 and the lower aperture 2 of the embodiment shown in figure are rectangle.
Showing in figure, the lower surface of upper cover 1 is welded with the plate 3 along upper cover 1 periphery, and plate 3 is vertical with the lower surface of upper cover 1.Plate 3 is made up of three ply board face, and three ply board face is vertically superposed to be connected as one, and the length in inner plating face 10 is the longest, and the length in intermediate plate face 11 and lamina rara externa face 12 gradually reduces, and the lower surface in three ply board face is formed stepped.
Figure shows, the plate 3 of upper cover 1 lower surface is relative with lower aperture 2, the inwall in lower aperture 2 is step shape, step 4 is three layers step, the three layers step 4 in lower aperture 2 is corresponding with the lower end ladder in the three ply board face of plate 3, the surface of orlop step is corresponding with the lower surface in the inner plating face 10 of plate 3, the surface of intermediate step is corresponding with the lower surface in the mesosphere board face 11 of plate 3, the surface of uppermost steps is corresponding with the lower surface in the lamina rara externa face 12 of plate 3, and the lower end in the three ply board face of plate 3 is press respectively against the upper surface of the three layers step of step 4.
Showing in figure, upper cover 1 and lower aperture 2 mode with bolts is attached.Periphery welding 6,8 fixed blocks of multiple fixed blocks 6 of upper cover 1 upper surface are uniform around upper cover 1 periphery, and there is opening 7 in the outside of fixed block 6.Having multiple bolt to fix seat 8 in neighboring, lower aperture 2, the position of the fixing seat 8 of bolt is relative with the position of the fixed block 6 of upper cover 1 periphery, and the fixing seat 8 of bolt has screw 9 corresponding with the outer openings 7 of fixed block 6.Upper cover 1 and lower aperture 2 are fastenedly connected by bolt 13 through opening 7 and screw 8, and owing to the quantity of fixed block 6 and the fixing seat 8 of bolt is 8, bolt 13 is far less than original flange bolt number, and therefore disassembly and assembly time shortens dramatically.
Showing in figure, there is angle of inclination the lower surface in the inner plating face 10 of upper cover 1 lower surface plate 3, intermediate plate face 11 and lamina rara externa face 12, forms knife-edge, and three layers knife-edge coordinates composition labyrinth sealing with the three layers step in lower aperture 2.
Figure shows, the upper surface of lower aperture 2 intermediate step has sealing ring 5, rise and strengthen sealing function.The lower surface, intermediate plate face 11 of upper cover 1 lower surface plate 3 is pressed on the sealing ring 5 on lower aperture 2 step 4, and the lower surface in intermediate plate face 11 and sealing ring 5 are in close contact, and sealing ring 5 can adopt high temperature resistant asbestos board or high temperature resistant asbestos cord or high temperature resistant asbestos pad.
