Description

Technical Field

[0001] The invention relates to the technical field of coke oven vent pipes, and in particular to an integrated coke oven vent pipe cover. Background Art

[0002] A vent pipe is a device specially used to discharge air or gas inside a pipeline. It releases gases with high pressure and fast flow rate, thereby protecting downstream equipment from overpressure. At present, the vent pipe cover is usually set in a split manner, consisting of two semicircular cover plates. During venting, the two cover plates rotate relative to each other to open the vent pipe. Since there is a gap between the two cover plates, the high-temperature exhaust gas during venting will impact the side of the cover plate, causing serious damage to the opposite end of the cover plate, shortening the service life of the cover plate. Moreover, sometimes the opening or closing of the vent pipe needs to rely on manual operation, which reduces the operating efficiency. The high-temperature exhaust gas generated during the venting of coke oven exhaust gas will cause high-temperature shock to the operator, posing certain safety hazards. Summary of the invention

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Integrated coke oven vent pipe cover, such as Figures 1 to 8 As shown, it includes a cylinder 1 and a cover plate 2 installed on the top of the cylinder 1. A turning mechanism for driving the cover plate 2 to turn over is installed on the cylinder 1, and the turning mechanism is connected to a driving mechanism integrally arranged on the cylinder 1.

[0021] The flipping mechanism includes a flipping arm 4, one end of which is connected to the cover plate 2, and both sides of the flipping arm 4 are respectively hinged to the support frame 3 symmetrically arranged on the side wall of the cylinder 1. The flipping arm 4 rotates under the drive of the driving mechanism, thereby driving the cover plate 2 to flip.

[0022] A second hinge seat 10 is arranged outside the support frame 3 , and the flip arm 4 is connected to the second hinge seat 10 via a hinge shaft 11 .

[0023] The support frame 3 is arranged in an inverted right triangle shape, and the support frame 3 is connected to the side wall of the cylinder 1 via a gasket 28 .

[0024] The driving mechanism includes a cylinder 9 mounted on the side wall of the cylinder 1 through a cylinder mounting seat 23. Figure 2 As shown, the movable end of the oil cylinder 9 is connected to the flip arm 4, and the flip arm 4 can rotate around the hinge shaft 11 through the extension and retraction of the movable end of the oil cylinder 9.

[0025] The driving mechanism can be directly welded to the side wall of the cylinder 1 , or connected to the cylinder 1 by welding a welding plate 22 that fits the side wall of the cylinder 1 to the side wall of the cylinder 1 .

[0026] The flip arm 4 includes two symmetrically arranged bending rods, such as Figure 6 As shown, the bending rod includes a horizontal portion 18 and a bending portion 19 , the horizontal portion 18 and the bending portion 19 are connected by a first reinforcing rod 20 , and the two bending portions 19 are connected by a plurality of second reinforcing rods 21 to ensure the stability of the flip arm 4 .

[0027] A horizontal mounting plate 6 is installed between the two support frames 3. Figure 5 As shown, one side of the mounting plate 6 is integrally arranged with the side wall of the cylinder 1, and the cover plate 2 is connected to the mounting plate 6 through a linkage mechanism. When the flip arm 4 rotates, the cover plate 2 can be lifted up for a distance to avoid wear at the contact point between the cover plate 2 and the cylinder 1, which affects the service life of the cover plate.

[0028] The linkage mechanism comprises a first hinge seat 7 symmetrically arranged on the mounting plate 6 , a pull rod 8 is hinged on the first hinge seat 7 , and the other end of the pull rod 8 is hinged to the cover plate 2 .

[0029] When the cover plate 2 is turned over by the turning arm 4 , the linkage mechanism cooperates with the movement of the cover plate 2 to realize the turning and resetting of the cover plate 2 .

[0030] A first reinforcing rib plate 14 and a second reinforcing rib plate 15 are disposed on the top of the cover plate 2 , and the first reinforcing rib plate 14 and the second reinforcing rib plate 15 are disposed cross-shaped.

[0031] The first reinforcing rib plate 14 is arranged parallel to the mounting plate 6 , and vertical connecting plates 12 are respectively arranged at both ends of the first reinforcing rib plate 14 , and the vertical connecting plates 12 are connected to the ends of the flip arms 4 .

[0032] A third reinforcing rib plate 16 is arranged at the end of the second reinforcing rib plate 15 near the mounting plate 6 . The third reinforcing rib plate 16 is arranged perpendicular to the second reinforcing rib plate 15 . Vertical side plates 17 are respectively arranged at both ends of the third reinforcing rib plate 16 . The bottom of the vertical side plate 17 is hinged to the pull rod 8 .

[0033] like Figure 3 As shown, a refractory fiber block 13 is also arranged inside the cover plate 2. When the high-temperature exhaust gas is discharged, the high-temperature exhaust gas is blocked by the refractory layer to prevent the high-temperature exhaust gas from directly contacting the cover plate 2 and preventing the cover plate 2 from being damaged by high-temperature impact.

[0034] Specifically, Figure 7 As shown, a threaded hole is provided in the middle of the refractory fiber block 13, a threaded groove is provided in the cover plate 2, a pad 27 is provided between the refractory fiber block 13 and the cover plate 2, and a bolt 26 passes through the center threaded hole of the refractory fiber block 13, the center threaded hole of the pad 27 and the threaded groove on the cover plate 2 at one time to be threadedly connected.

[0035] A counterweight 5 is provided at the end of the flip arm 4 away from the cover plate 2. The weight of the counterweight 5 is greater than the weight of the cover plate 2. When the oil cylinder in the driving mechanism fails, the counterweight 5 can drive the cover plate 2 to flip under the action of its own gravity, open the discharge pipe to release the high-temperature exhaust gas, and avoid the accumulation of high-temperature exhaust gas inside the discharge pipe to form a safety hazard.

[0036] The number of the counterweight blocks 5 can be selected according to actual needs. In the present embodiment, the number of the counterweight blocks 5 is two, and the counterweight blocks 5 are mounted on the flip arm 4 via a bolt assembly.

[0037] The lower part of the cylinder 1 is also provided with a buffer mechanism 25 for buffering. Figure 8 As shown, the buffer mechanism includes a bottom plate 29, a top plate 30 and a buffer spring 31, one end of the buffer spring 31 is connected to the top plate 30, and the other end of the buffer spring 31 is connected to the bottom plate 29. The bottom plate 29 is installed on the side wall of the cylinder 1 and is tilted upward.

[0038] The bottom plate 29 is mounted on the extension frame 24 on the cylinder 1. The bottom plate 29 is provided with a lower sleeve 32 sleeved on the side of the buffer spring 31. The top plate 30 is provided with an upper sleeve 33 sleeved on the side of the buffer spring 31. The lower sleeve 32 is slidably mounted inside the upper sleeve 33.

[0039] When it is necessary to open the diffusion pipe, the movable end of the cylinder 9 is contracted to drive the flip arm 4 to rotate around the hinge shaft 11. At the same time, with the cooperation of the linkage mechanism, the cover plate 2 is lifted up for a distance and then flipped to avoid wear between the cover plate 2 and the cylinder 1 when flipping, thereby opening the diffusion pipe to discharge the exhaust gas.

[0040] At the same time, the flip arm 4 contacts the buffer mechanism after flipping to a certain angle, and slowly stops rotating under the action of the buffer mechanism, so as to prevent the flip arm 4 from hitting the cylinder and causing damage to the cylinder.

[0041] When it is not necessary to release, the movable end of the oil cylinder 9 extends out to press the flip arm 4 upward to prevent the flip arm 4 from rotating under the deadweight of the counterweight 5, so that the cover plate 2 covers the cylinder 1 to block the release pipe.

[0042] The cover plate in the present invention is integrally formed, which solves the problem that the split type pipe cover is easily damaged by the impact of exhaust gas due to the gap in the center of the pipe cover. When the flipping mechanism drives the cover plate to rotate, a linkage mechanism is provided so that when the flipping mechanism drives the cover plate to rotate, the cover plate can be lifted up a distance first, away from the cylinder body, and then flipped, thereby avoiding wear at the contact point between the cover plate and the cylinder body. At the same time, a refractory fiber block is provided inside the cover plate, which can avoid the cover plate from being damaged by high-temperature impact and improve the service life of the cover plate.

[0043] The present invention also provides a buffer mechanism so that when the flip arm rotates to the limit, it can gradually stabilize under the buffering of the buffer mechanism, thereby preventing the flip arm from directly hitting the cylinder when flipping downward and causing damage to the discharge pipe, thereby improving the safety of operation.

[0044] Since the cover plate, cylinder, flip mechanism and driving mechanism are arranged in one piece, the release pipe can be released quickly, which improves the operating efficiency. At the same time, there is no need for manual operation to open the release pipe, which avoids high-temperature damage to the human body caused by high-temperature exhaust gas when the release pipe is opened, thus ensuring the safety of the equipment during operation.
