Abstract
The utility model relates to a carbon roasting furnace belonging to the field of nonferrous metal, in particular to a sealing device for steel flue of the carbon roasting furnace which is used for separating flue of the roasting furnace from outside so as to assure normal smoke emission of the roasting furnace. The sealing device consists of a flue opercle(6) and a hole seat(7) of the flue. The flue opercle(6) comprises an upper cover plate(3) and a lateral steel plate(4). Edge of the cover plate(3) is connected with a flexible sealing board(5), and the flexible sealing board(5) stretches beyond rim of the hole seat(7) of the flue. The sealing device of the utility model has the advantages of agile operation, high temperature resistance, economical and practical use as well as low labor intensity.
Description
Technical field
The utility model relates to the carbon baking furnace that a kind of nonferrous metallurgy field is used, and particularly relates to a kind of carbon baking furnace steel flue gas duct sealing device, and in order to cut off the passage between the calcining kiln flue and the external world, the assurance roaster is normally discharged fume.
Background technology
The roaster steel flue gas duct is the main sealing device of steel flue gas duct with the flue port lid, is the corollary equipment that matches with the floss hole seat and use.Be mainly used in the passage that cuts off between calcining kiln flue and the ambient atmosphere, cold air enters steel flue gas duct inside in the prevention roasting workshop, and cooperates flue outlet place blower fan to realize the negative-pressure operation of steel flue gas duct inside, to guarantee the normal smoke evacuation of stove.Therefore, the flue port lid is one of critical piece of whole roaster smoke evacuation system.
The sealing of existing flue port lid and floss hole seat is relatively poor, in practical operation, often has cold air to enter flue inside from interface, and the negative pressure of flue inside is reduced, and influence is smoke evacuation normally.Also, caused unnecessary heat loss, thereby reduced the thermal efficiency of whole body of heater because cold air is taken away a part of heat.In actual production, for fear of above-mentioned influence, the workman covers the effect that face bedding plastic sheeting plays sealing at floss hole, stops entering of cold air, guarantees the negative pressure requirement of flue inside in order to normal smoke evacuation.But plastic sheeting in use, and following shortcoming is arranged: 1. heat resisting temperature is lower, and when flue port lid temperature was too high, glued shape can appear in plastics, directly influences its service life, and had caused unnecessary waste; 2. when beginning to discharge fume along with the smoke evacuation frame, need open the plastics of covering again at every turn, remove the smoke evacuation of flue port lid again, periodic mobile plastics have increased working strength of workers, influence operating efficiency; 3. attractive in appearance and poor practicability.
The utility model content
The utility model provides a kind of carbon baking furnace sealing device, purpose exactly in order to solve the problems of the technologies described above be that the existing sealing device sealing of solution is relatively poor, and service life is short, the problem that working strength of workers is big.
In order to solve the problems of the technologies described above, the utility model is achieved in that a kind of carbon baking furnace sealing device, it comprises flue port lid and floss hole seat, the flue port lid comprises upper cover plate and sidepiece steel plate, wherein the edge of upper cover plate is connected with the flexible sealing plate, and the flexible sealing plate stretches out floss hole seat edge.
The thickness of described flexible sealing plate is identical with the thickness of upper cover plate.
Described upper cover plate is provided with handle, and handle is connected with upper cover plate by steel pipe.
The height of described sidepiece steel plate is identical with the outer steel plate height of floss hole seat groove both sides.
The utility model sealing device flue port lid has increased the flexible sealing plate than existing flue port lid, promptly connect the flexible sealing plate of suitable thickness and length in the former floss hole panel edges that closes the lid, the opposite side of flexible sealing plate in the raw, make the flexible sealing plate take steel plate top outside the floss hole seat just naturally, to reach the state of nature sealing.The utility model sealing device has the following advantages:
1. to cover cover plate be an integral body for flexible sealing plate and floss hole, moves with the mobile and corresponding of port lid, flexible to operation.
2. flexible material is anticorrosive high temperature resistant, long service life.
3. science is reliable, and is economical and practical, need not increase additional effort.

Among the figure, 1, handle; 2, steel pipe; 3, upper cover plate; 4, sidepiece steel plate; 5, flexible sealing plate; 6, flue port lid; 7, floss hole seat; 8, outer steel plate.
The specific embodiment
Below embodiment of the present utility model is described in detail in conjunction with the accompanying drawings, but protection domain of the present utility model is not limit by embodiment.
As shown in Figure 3, a kind of carbon baking furnace of the utility model is as follows with sealing device structure: it comprises flue port lid 6 and floss hole seat 7.Flue port lid 6 structures comprise upper cover plate 3 and sidepiece steel plate 4 as depicted in figs. 1 and 2, and wherein the edge of upper cover plate 3 is connected with flexible sealing plate 5, the opposite side of flexible sealing plate 5 in the raw, flexible sealing plate 5 stretches out floss hole seat 7 edges.The thickness of flexible sealing plate 5 is identical with the thickness of upper cover plate 3.Upper cover plate 3 is provided with handle 1, and handle 1 is connected with upper cover plate 3 by steel pipe 2.The height of sidepiece steel plate 4 is highly identical with the outer steel plate 8 of floss hole seat 7 groove both sides.
As shown in Figure 4, operation principle of the present utility model is as follows: when floss hole seat 7 was in running order, a, b position be because the slit appears in steel plate contact difference, directly causes the groove c place formation negative pressure that communicates with steel flue gas duct.This moment, flexible sealing plate 5 both sides were owing to be subjected to the differential pressure action of atmosphere and flue gas, elastic deformation takes place, and cave in to the groove direction of negative pressure, see and be out of shape shown in the back among the figure, increase along with negative pressure, elastic deformation also increases thereupon, so just make the flexible sealing plate 5 of d position tightly be affixed on outer steel plate 8 tops of floss hole seat 7, along with elastically-deformable increase, the also corresponding enhancing of the sealing of d position, thereby formed " from the trivial " phenomenon that forms because of both sides pressure reduction, realized the function of sealing reliably.
