Abstract
The utility model discloses an uneasily damaged coke oven coaling hole cover, which belongs to the technical field of coke oven equipment. The cover is used for sealing a coaling hole in the top of a carbonization chamber of a coke oven. According to the technical scheme, an inner chamber for filling refractory mortar is arranged between a top side and a bottom side of the cover; a plurality of refractory mortar filling holes are formed in the top side of the coaling hole cover; a plurality of reinforcing rib plates are arranged inside the inner chamber of the coaling hole cover; the reinforcing rib plates are perpendicular to the bottom side; the upper ends and the lower ends of the reinforcing rib plates are respectively connected with the lower surface of the top side and the upper surface of the bottom side. As three refractory mortar filling holes are formed in the top surface of the cover, refractory mortar can be conveniently filled into the coaling hole cover, and the burning loss of an electromagnetic component because of high temperature caused when the refractory mortar drops off is effectively prevented; as the reinforcing rib plates are arranged inside the inner chamber of the coaling hole cover, the overall strength of the coaling hole cover is improved, and the coaling hole cover is prevented from being damaged by collision of the electromagnetic component. The cover has the advantages of simple structure, high strength, damage uneasiness and good insulating effect, prolongs the service life, and is worthy of popularization.
Description
Technical field
The utility model relates to a kind of for sealing the coaling charging hole lid of coke oven in hole of coke furnace carbonization chamber top, belongs to coke oven for iron technical field.
Background technology
In coke oven is produced, charging hole lid is positioned at coking furnace shaft coking chamber top, for sealing the hole of coalingging, because the temperature of charging hole lid position is more than 800 DEG C, the quality of charging hole lid stopping property is burned with anger and charging hole seat scaling loss distortion, losing efficacy has substantial connection to preventing that oven top of coke oven from smoldering, and therefore charging hole lid is also very important furnace retaining equipment.Common charging hole lid is all to adopt vermicular cast iron to make at present, its structure is that upper surface integral sealing lower surface is opened a circular hole, and cavity is left in centre, fills refractory mortar in use in cavity, play heat insulation importantly, prevent that excess Temperature from causing damage to the electromagnet assembly of uncovery mechanism.In real work, coal charger electromagnet assembly in the time taking off lid operation inevitably can strike charging hole lid, causes the refractory mortar in charging hole lid to come off, and therefore, common charging hole lid is shorter work-ing life, can cause serious scaling loss to electromagnet assembly simultaneously.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of long service life, can avoid electromagnet assembly scaling loss, be convenient to fill the non-damageable charging hole lid of coke oven of refractory mortar.
The technical scheme solving the problems of the technologies described above is:
A kind of non-damageable charging hole lid of coke oven, its end face center is circular flat, circular flat circumferential ring is around the annulus tilting downwards, between end face and bottom surface, for filling the inner chamber of refractory mortar, its improvements are that the bottom surface of charging hole lid is integral planar, the end face of charging hole lid has multiple refractory mortar filling orifices, in the inner chamber of charging hole lid, have multiple reinforcement gussets, strengthen gusset vertical with bottom surface, the two ends up and down of strengthening gusset are connected with bottom surface upper surface with end face lower surface respectively.
Above-mentioned non-damageable charging hole lid of coke oven, the refractory mortar filling orifice of the end face of described charging hole lid is three, three refractory mortar filling orifices are along the circumference uniform distribution of charging hole lid.
Above-mentioned non-damageable charging hole lid of coke oven, described reinforcement gusset is elongated plates, strengthens the major axis of gusset and the radius of a circle of charging hole lid and overlaps, and strengthens gusset for three and lays respectively between refractory mortar filling orifice.
The beneficial effects of the utility model are:
End face of the present utility model has three refractory mortar filling orifices, is convenient in charging hole lid, supplement refractory mortar at any time, has effectively prevented from causing the high scaling loss to electromagnet assembly of temperature because refractory mortar comes off; In the inner chamber of charging hole lid, increase reinforcement gusset, can improve the bulk strength of charging hole lid, prevented from damaging because electromagnet assembly clashes into.The utlity model has simple in structure, intensity is high, the advantage of not fragile, good heat-insulation effect, has not only extended work-ing life, has also effectively avoided electromagnet assembly scaling loss, be worthy of popularization.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
In figure, mark is as follows: end face 1, bottom surface 2, inner chamber 3, refractory mortar filling orifice 4, strengthen gusset 5, choose and cover hole 6.
Embodiment:
In figure, show, the utility model comprises end face 1, bottom surface 2, inner chamber 3.End face 1 center is circular flat, and circular flat circumferential ring, around the annulus tilting downwards, is chosen and covered hole 6 on end face 1.Bottom surface 2 is integral planar, is the inner chamber 3 of filling refractory mortar between end face 1 and bottom surface 2.
In figure, show, the end face 1 of charging hole lid has three refractory mortar filling orifices 4, three refractory mortar filling orifices, along the circumference uniform distribution of charging hole lid, are convenient in charging hole lid, supplement refractory mortar at any time, have effectively prevented from causing the high scaling loss to electromagnet assembly of temperature because refractory mortar comes off.
In figure, show, in the inner chamber 3 of charging hole lid, there are multiple reinforcement gussets 5, strengthening gusset 5 is elongated plates, strengthening the major axis of gusset 5 and the radius of a circle of charging hole lid overlaps, article three, strengthening gusset 5 lays respectively between refractory mortar filling orifice 4, strengthen gusset 5 vertical with bottom surface 2, the two ends up and down of strengthening gusset 5 are connected with bottom surface 2 upper surfaces with end face 1 lower surface respectively.Strengthen the bulk strength that gusset 5 can improve charging hole lid, prevent from damaging because electromagnet assembly clashes into.
Charging hole lid of the present utility model is to cast and form with vermicular cast iron, and refractory mortar is the special pseudo-ginseng material of coke oven.
