Through seting up breach 6, during the installation, breach 6 is used for avoiding second post 2, pushes dust cage 3 along the horizontal direction between two first posts 1, reuse baffle 7 seal breach 6 can, the installation is more convenient. In practice, the baffle 7 may be detachably connected to the dust hood 3 by screws.
In fact, a gap inevitably exists between the bottom end of the dust hood 3 and the coke oven, which may cause smoke to leak, so, in some embodiments, referring to fig. 1 and 3, the bottom end of the dust hood 3 is higher than the coke oven, a sealing plate 8 is further connected below one side of the dust hood 3 close to the coke oven, and the sealing plate 8 is used for sealing a gap between the dust hood 3 and the coke oven. The gap between the dust collecting cover 3 and the coke oven is sealed by the sealing plate 8, so that on one hand, the leakage of smoke dust is avoided, and on the other hand, the tightness of the airtight space 5 is increased, and the smoke dust is more easily sucked.
Illustratively, the closure plate 8 may be a metal plate; alternatively, the closure plate 8 may be a concrete slab. When the sealing plate 8 is a metal plate, the sealing plate 8 can be welded on the dust hood 3 in a full-welding mode, and then a tiny gap between the sealing plate 8 and the coke oven is sealed by refractory clay and the like; when the sealing plate 8 is a concrete plate, the concrete can be directly poured into a gap between the coke oven and the dust collecting cover 3 during installation, and the sealing plate 8 is formed after the concrete is dried.
In some embodiments, referring to fig. 1, each first column 1 further has a horizontally disposed smoke baffle 9, the height of the smoke baffle 9 is greater than or equal to the height of the oven door, and two sides of the dust hood 3 are respectively connected to the smoke baffles 9 of the corresponding first column 1. By arranging the smoke baffle 9, on one hand, the smoke dust overflow caused by the gap between the coke pusher and the furnace column can be avoided; on the other hand, the bottom surface of each dust collection cover 3 can be ensured to be smooth through the smoke baffle 9, so that the probability of smoke overflow is reduced.
Illustratively, the dust hood 3 may be connected to the smoke baffle 9 by welding or the like, and this connection may fix the dust hood 3 relatively firmly; in another alternative embodiment, the dust hood 3 can be detachably connected with the smoke baffle 9 through screws and the like, so that the dust hood is convenient to replace and maintain; when the dust hood 3 is detachably connected with the smoke baffle 9 by screws, a minute gap between the smoke baffle 9 and the dust hood 3 can be blocked by fire-proof mud or the like.
In some embodiments, referring to fig. 1 to 3, the dust collecting device may further include a branch pipe 10 for conveying the dust collected by the dust collecting cover 3, and a valve 11 for controlling the on/off of the dust collecting cover 3 is disposed between the branch pipe 10 and the dust collecting cover 3; the outside of the valve 11 is also provided with a protective cover 12, and the protective cover 12 is used for preventing the flame of the coke oven from damaging the valve 11. The protection cover 12 may be annular around the valve 11, or the protection cover 12 may be plate-shaped to block the flame, so long as the flame is prevented from directly contacting the valve 11.
Another object of the present utility model is to provide a coke oven, comprising the dust collecting device, wherein the first columns 1 are arranged at two sides outside at least two oven doors of the coke oven, and the dust collecting cover 3 of the dust collecting device is connected to the two first columns 1.
