Embodiment
below in conjunction with drawings and Examples in detail the present invention is described in detail:
a kind of air-supply apparatus of blast furnace peep hole assembly, see in accompanying drawing 1 to accompanying drawing 9, figure: spy on port lid 1, support ring 2, spinning chuck 3, elbow body 4, web plate 5, window flange 6, bearing pin 7, connection handle 8, claw 9, stiffening web 10, wedge block 11, projection 12, groove 13, V-seal groove 14, coated pad 15, extension rod 16, briquetting 17; Connect support 18, peep hole 19, spinning grab 20, refractory casting layer 21, shoulder 22.
in the present embodiment, window flange 6 is connected with elbow body 4, and window flange 6 is provided with spinning grab 20, spies on port lid 1 and spinning chuck 3 is housed, and spinning chuck 3 and spinning grab 20 spin.
spinning chuck 3 is provided with claw 9, and claw 9 is distributed on spinning chuck 3 in 120 degree, and spinning grab 20 is distributed on the internal diameter of window flange 6 in 120 degree; The internal diameter of window flange 6 is step-off construction; The larger diameter end of window flange 6 is provided with spinning grab 20, the smaller diameter end of window flange 6 is connected with elbow body 4; Claw 9 is fastening with spinning grab 20 spinning.
spinning grab 20 and claw 9 are respectively equipped with the gradient face of 1:10; Claw 9 is placed on the external diameter of spinning chuck 3; Spinning grab 20 contacts with the gradient face spinning of both claws 9.
spinning chuck 3 is provided with protruding 12, and window flange 6 is provided with groove 13; Protruding 12 embed in groove 13; Groove 13 and protruding 12 is respectively equipped with V-seal groove 14.
both projection 12 and groove 13 go up set V-seal groove 14 in staggered arrangement; Shown in Figure 2; Groove 13 is built with coated pad 15; The V-seal groove 14 of staggered arrangement defines S type seal channel, more effectively can be filled between spinning chuck 3 and window flange 6 by metallic cover pad 15, play good sealing function.
spy on port lid 1 and be provided with shoulder 22, shoulder 22 is set with support ring 2; Spy on port lid 1 to rotate freely in support ring 2, support ring 2 is hinged by the web plate 5 that connection handle 8 and elbow body 4 are installed; Elbow body 4 is built with refractory casting layer 21.Connection handle 8 and web plate 5 are set to two respectively, and wherein two connection handles 8 connect by connecting support 18.
