A kind of furnace cover of closed type calcium carbide furnace, comprise edge bell and center bell, the edge bell is put together by bell unit, even numbered blocks edge, every block edge bell unit all is comprised of cover plate and side plate, side plate is fixed on the outer rim of cover plate, the mode block-by-block that each block edge bell unit aligns successively with the side of cover plate pieces together regular polygon or the circular edge bell that through hole is left at center, the mode that the side plate of each block edge bell unit connects successively with head and the tail pieces together the annular side plate of sealing, the shape of center bell and size all with edge bell unit amalgamation after the shape of the central through hole that forms and measure-alike, the center bell is embedded in the central through hole place formed after edge bell unit amalgamation, between adjacent bell unit, edge, lining is with insulation board, all use bolted between adjacent bell unit, edge and between bell unit, edge and center bell,
It is characterized in that: also comprise electrode guide, blanking seat, bell pin, insulating pad, detection hole, inspection door, flue seat, pressure relief device and access cover,
Have electrode hole on the edge bell, electrode hole is uniformly distributed around the center of edge bell, the center superposition of the center and peripheral bell of the regular polygon that center of electrode hole connects and composes successively;
The bottom of electrode guide is the flange-like base, the flange-like base consists of several sections arcs, the flange-like base of electrode guide is fixed by bolts on the edge bell and center bell of outer rim of electrode hole, the through hole of electrode guide and electrode hole alignment;
Be provided with five blanking holes around each electrode guide, in five blanking holes, a blanking hole is located on the center bell that is positioned at the electrode guide inboard, and another four blanking holes are located at respectively on the bell unit, edge adjacent with electrode guide;
Each blanking hole is provided with a blanking seat, the through hole of blanking seat and blanking hole alignment, and fire-resistant stamp mass sealing is all used in the gap between the gap between blanking seat and bell unit, edge and blanking Zuo He center bell;
The below of edge bell annular side plate is provided with the bell pin, and the below of bell pin arranges insulating pad, has on the annular side plate of edge bell and detects hole and inspection door, and the cover plate of edge bell is provided with flue seat, pressure relief device and access cover.
Described furnace cover of closed type calcium carbide furnace is characterized in that: bell unit, edge has six, and two formed angles of side of cover plate are 60 °; The outer rim of cover plate is selected straightway, at least three straightways any one in the circular arc of 60 °, the broken line of end to end formation and central angle successively.
The utility model is the straight section formula by traditional tapered electrode water-cooled seal sleeve designs simplification, has removed the following part of former water cooled seal seat, retains its seal receptacle, top hold-down.Electrode water-cooled sealing device directly leans on bolted with edge bell and center bell, reduced the height of electrode sealing shroud, thereby reduced electrode travel, be provided with insulation board between bell and sealing shroud, sealing and insulation effect are better, due to designs simplification, bell central area weight also reduces to some extent.
The utility model combines the characteristics of height bell, and electrode sealing shroud position is lower on the one hand, has reduced the stroke of electrode, has overcome the shortcoming of high bell; The shorter bell form in edge bell, center bell and feed opening position increases on the other hand, increased the bell space, due to the material mouth from charge level away from, material mouth environment temperature of living in is relatively low, reduced material mouth scaling loss probability, and descending material still can be realized electrode is better coated.
The beneficial effects of the utility model are: changed former furnace cover of closed type calcium carbide furnace form, simplified the structure of electrode water cooling sealed guiding device, can reduce the exposed length of electrode, reduced electrode travel, be conducive to reduce the calcium carbide melting electric consumption; Can guarantee the useful space of bell again, stablize furnace pressure, be conducive to calcium carbide production and carry out smoothly.
