Abstract
An improved coke dry quenching furnace lid belongs to the technical field of coke oven plants, and aims to solve the problems of frequent replacement of the device and severe influence on the production of the coke dry quenching device caused by the damage of the furnace lid. The utility model adopts the technical scheme that the outer main body of the furnace lid is formed by welding an inner-skirt top plate, an outer-skirt top plate, an inner skirt, an outer skirt and lifting lugs; a heat insulation plate is mounted below the inner-skirt top plate; a heat insulation cavity is formed between the heat insulation plate and the inner-skirt top plate; a high-temperature resistant fiber blanket material is laid on the lower surface of the heat insulation plate; the lower part of the fiber blanket material is compressed by a pressure plate; a fire-proof casting material is cast under the pressure plate; and the fiber blanket material, the pressure plate and the fire-proof casting material are all closely connected with the inner circumferential wall of the inner skirt. The utility model has the advantages that an air heat insulating layer is arranged at the topmost part of the furnace lid, thereby lightening the unit weight of the device and improve the heat insulation effect; moreover, fire-proof materials with different properties are not in contact with one another, thereby avoiding the shedding of the fire-proof materials caused by the lamination and delamination during the use.
Description
Technical field
The utility model relates to a kind of dried oven coke stove bell that puts out, and belongs to the coke oven plant technical field.
Background technology
The coke dry quenching furnace bell is to be positioned at the dried oven coke loading port that puts out, and drives to seal the dried stove fire door that puts out with draw-gear, realizes the visual plant that intermittent red Jiao packs into.Because the particularity of environment for use, high temperature about equipment must bear up to 1000 ℃ and frequent heat are shaken.The manufacturing technology that the coke dry quenching furnace bell that was in the past adopted is adopted is 2 layers of refractory material of liner, one deck is for building heat-barrier material, one deck is for building exotic material, in the use since material between effect, the factors such as operating characteristic that material burns till dehydration and material itself cause easily peels off, layering, situations such as be full of cracks, simultaneously owing to adopt two-layer refractory material to cause the equipment substance overweight, cause great burden to drive unit, reduced the operational reliability of equipment, increase the operation energy consumption of equipment, had a strong impact on the service life of bell and the safe and stable operation of dry quenching system.Therefore, existing coke dry quenching furnace bell being improved is one of important topic in the coke dry quenching furnace equipment technical field.
Summary of the invention
Defectives such as technical problem to be solved in the utility model provides a kind ofly can overcome the be full of cracks of dry coke quenching bell refractory material, layering, peel off and equipment self-weight is overweight, the equipment that causes is frequent to be changed and dry coke quenching auxiliary is produced the suffered improved coke dry quenching furnace bell that has a strong impact on because bell damages thereby solve.
The technical scheme that solves the problems of the technologies described above is:
A kind of improved coke dry quenching furnace bell, its bell outer body is by the underdress top board, the shell top board, underdress, shell and hanger are welded, its improvements are, below the underdress top board, thermal insulation board has been installed, the inner peripheral wall of thermal insulation board and underdress is welded to connect, form a heat insulation cavity between thermal insulation board and the underdress top board, the lower surface of thermal insulation board is laid resistant to elevated temperatures tapetum fibrosum material, the following of tapetum fibrosum material compressed by pressing plate, cast refractory casting material below pressing plate, the tapetum fibrosum material, pressing plate, the refractory casting material all closely is connected with the inner peripheral wall of underdress.
Above-mentioned improved coke dry quenching furnace bell is evenly equipped with a plurality of radiate heat and ventilate hole on the described thermal insulation board.
Above-mentioned improved coke dry quenching furnace bell, the lower surface of described thermal insulation board is welded with a plurality of crab-bolts, and crab-bolt is vertically placed, the upper end is connected with the thermal insulation board lower surface, the crab-bolt bar passes tapetum fibrosum material and pressing plate, and pressing plate is compressed, and the crab-bolt pawl of crab-bolt lower end is cast in the refractory casting material.
Above-mentioned improved coke dry quenching furnace bell, described crab-bolt is two body structures, and top is the crab-bolt bar, and the bottom is the crab-bolt pawl, and there is screw thread the upper end of the lower end of crab-bolt bar and crab-bolt pawl, and the centre has the crab-bolt nut that two parts are connected.
Advantage of the present utility model is: the topmost at bell has an air heat-insulation layer, has alleviated the equipment substance, has improved effect of heat insulation; Refractory material of different nature does not contact mutually, the layering that has occurred in having avoided using, peels off the refractory material that causes and comes off; The employing crab-bolt is installed, and refractory material connects more firm.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a crab-bolt structural representation of the present utility model.
Mark is as follows among the figure: underdress top board 1, shell top board 2, shell 3, underdress 4, hanger 5, heat insulation cavity 6, tapetum fibrosum material 7, thermal insulation board 8, refractory casting material 9, pressing plate 10, crab-bolt 11, radiate heat and ventilate hole 12, crab-bolt bar 13, crab-bolt nut 14, crab-bolt pawl 15.
The specific embodiment:
Show among the figure that the outer body of bell is welded by shell 3, shell top board 2, underdress 4, underdress top board 1 and hanger 5.
Heat-resisting steel sheet and plate is separated out a heat insulation cavity 6 as thermal insulation board 8 below underdress 4 inside, underdress top board 1, as air heat-insulation layer, reduce weight of equipment, increases effect of heat insulation.Get some radiate heat and ventilate hole 12 on the thermal insulation board 8 of cavity, the water vapour that assurance bottom refractory casting material 9 is separated out when burning till can be discharged smoothly.
Crab-bolt bar 13 upper ends of crab-bolt 11 are welded on thermal insulation board 8 bottoms, be close to the thermal insulation board 8 resistant to elevated temperatures tapetum fibrosum material 7 of mating formation, and make the screw thread exposed fiber blanket material 7 of crab-bolt bar 13, tapetum fibrosum material 7 usefulness pressing plates 10 compress, crab-bolt bar 13 screw threads expose from the perforate of pressing plate 10, the crab-bolt nut 14 of crab-bolt 11 is installed on the crab-bolt bar 13, and in order to fixation clip 10, the crab-bolt pawl 15 of crab-bolt 11 is installed to the other end of crab-bolt nut 14.Be close to pressing plate 10 and build the fire-resistant material 9 of building of one deck, the fire-resistant material 9 of building covers crab-bolt 11 fully.Build finish after natural air drying, be baked to sclerosis then.
