Abstract
The utility model discloses a flame path hole of a roasting furnace. A flame path sleeve is disposed on the periphery of a flame path ring, and a sealing part is arranged between the flame path ring and the flame path sleeve. After the sealing ring deforms in a high-temperature roasting process, sealing effect to a contact surface of the flame path ring and a combustor base can be realized when the roasting furnace is heated, external cold air which enters a flame path is reduced, and fuel consumption is lowered. When the roasting furnace is cooled, sealing effect can be realized to the contact surface of the flame path ring and an observation cover, hot air which flows from the inside of the flame path to the external is reduced, and heat loss is decreased.
Description
Technical field
The utility model relates to a kind of baking furnace flame path hole, particularly a kind of anode roasting fire path pore structure.
Background technology
The anode roasting fire path circle is set in the cast iron circle in the casting material when making prefabricated material piece, and the quirk circle exposes quirk wall 10～30mm.In the roasting process, the quirk circle is in the condition of high temperature for a long time, is prone to make quirk circle generation high-temperature oxydation and produces distortion.Burner base adopts cast iron and high temperature resistant material to be made, and when roasting, burner base is placed on the quirk circle; In quirk, spray fuel; Be negative pressure state in the quirk, because the quirk circle deforms in roasting process, it is poor that burner base is placed on the quirk circle sealing; Cause in roasting process, having a large amount of cold airs to enter in the quirk from the slit between burner base and the quirk circle; Influence baking furnace flame path intensification effect, need to increase fuel and satisfy the intensification demand, cause the waste of fuel.At the roaster cooling stage, be barotropic state in the quirk, because the quirk circle deforms, cover observation lid and the poorly sealed reality of quirk circle on the quirk circle, the heat in the quirk is run out of from the slit, causes thermal loss.
The utility model content
The purpose of the utility model is in order to overcome above difficulty, a kind of good seal performance to be provided, the baking furnace flame path hole of energy savings.
The technical scheme of the utility model is:
A kind of baking furnace flame path hole comprises the quirk wall, fire channel, and the quirk circle is provided with the quirk cover in the periphery of said quirk circle, between said quirk circle and said quirk cover, seal is set.
Further, said quirk cover is placed on the said quirk wall.
Further, the upper surface of said quirk cover is higher than the upper surface of said quirk circle.
Further, said seal is high temperature resistant asbestos material, a kind of in the ceramic fibre material.
Further, said quirk circle embeds said quirk within the walls.
The baking furnace flame path hole that the utility model provides; Quirk cover and seal are set outside the quirk circle, seal be arranged on the quirk circle expose quirk wall part around, after the quirk circle deforms in high-temperature calcination process; When roasting furnace temperature elevation; Can play sealing function to the contact-making surface of quirk circle and burner base, reduce extraneous cold empty the entering in the quirk, reduce fuel consumption; When roaster cools off, can play sealing function to quirk circle and the contact-making surface of observing lid, reduce the interior hot-air of quirk and flow out to the external world, reduce thermal loss.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment; To do briefly clearly to introduce to the accompanying drawing of required use among the embodiment below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the cutaway view in the utility model quirk hole;
Fig. 2 is the vertical view in the utility model quirk hole;
Fig. 3 is the cutaway view behind the install combustion device pedestal of the utility model quirk hole;
Reference numeral: 1-quirk wall, 2-fire channel, 3-quirk circle, 4-quirk cover, 5-seal, 6-burner base, 7-burner interface.
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is a part of embodiment of the utility model, rather than whole embodiment.Based on the embodiment of the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The specific embodiment is following:
In conjunction with Fig. 1, Fig. 2, the baking furnace flame path hole comprises quirk wall 1, fire channel 2, and quirk circle 3 is provided with quirk cover 4 in the periphery of quirk circle 3, between quirk circle 3 and quirk cover 4, seal 5 is set, and it is loop configuration that quirk overlaps 4.
The upper surface of quirk cover 4 is higher than the upper surface of quirk circle 3, makes 5 pairs of quirk circles of sufficient seal 3 carry out tight sealing on every side, guarantees its sealing.
Seal 5 optional high temperature resistant asbestos materials, a kind of in the ceramic fibre material, high temperature resistant and sealing property is good.
When the quirk circle is installed, quirk circle 3 is embedded in the quirk walls 1, when the quirk circle after high-temperature roasting deforms, can not become flexible yet, thereby strengthen the steadiness of quirk pore structure.
In use; When anode-baking, burner base 6 is installed on the quirk circle 3, combustion gas gets in the quirk from burner interface 7; The bottom of burner base 6 closely contacts with seal 5; Even quirk circle 3 distortion backs produce the slit with the contact-making surface of burner base 6, the outside air-flow of quirk can not get in the quirk yet, and influences the temperature in the quirk; When roaster cools off, take off burner base 6, on quirk circle 3, place handhole cover; Equally; Because of handhole cover closely contacts with seal 5, make the hot-fluid in the quirk be unlikely to flow to the quirk outside the slit between quirk circle 3 and handhole cover, cause the loss of heat.
Preferably the external diameter than burner base 6 is big for the internal diameter of quirk cover 4, and is during replacing between burner base and the handhole cover, easy to operate.
