Abstract
A sealing device for a well-type throat opening comprises a furnace cover cooling cavity, a furnace cover sealing ring, a muffle guiding groove, a sealing ring, a muffle cooling cavity, a furnace cover and a muffle furnace body. The furnace cover cooling cavity is fixed on the top face of the furnace cover. The furnace cover sealing ring is fixed on the edge of the bottom face of the furnace cover. The muffle cooling cavity is fixed at the outer side of the top end of the muffle furnace body. The muffle guiding groove is fixed on the top face of the muffle cooling cavity. The sealing ring is fixed between the furnace cover sealing ring and the muffle sealing groove. According to the sealing device for the well-type throat opening, inclined face pressure of the furnace cover sealing ring and a location effect of the muffle guiding groove are used for enabling the sealing ring to be extruded to transform, a sealing effect is strengthened, full sealing between a furnace body and the furnace cover is achieved through the shape of the sealing ring after transformation, the problems that existing plane sealing is small in contacted face, a sealing face is prone to pollution, and sealing is not accurate and other problems are solved, reliability and safety of sealing of devices are effectively improved.
Description
Technical field
The utility model patent relates to the elevated-temperature seal technology, specifically refers to the Sealing Technology of shaft furnace fire door.
Background technology
Shaft furnace is in service at equipment, and bell need often be opened the lifting workpiece, need between Ma Fu and bell a kind of not only tightly but also accurate sealing device.In the past sealing device adopts the round steel on the bell face to be pressed into the not packing structure on face of horse, and because contact-making surface is little, compression distance is shallow, usually causes bell poorly sealed, and so air might enter in retort; Furnace gas is harmful to operating personnel and environment, and furnace gas leaks, and has a strong impact on production safety.
The utility model content
The technical problems to be solved in the utility model is to overcome existing defective, and a kind of sealing device that is used for reliably the shaft furnace mouth is provided, and solves existing shaft furnace poorly sealed, the defective that furnace gas leaks.
A kind of sealing device for the shaft furnace mouth of the utility model comprises: bell cooling chamber, bell sealing ring, horse be not cooling chamber, bell and Muffle furnace body of gathering sill, sealing ring, horse not, and described bell cooling chamber is fixed in the bell end face; Described bell sealing ring is fixed in the bell bottom edge; Described horse not cooling chamber is fixed in the outside, Muffle furnace body top; Described horse not gathering sill is raised in not cooling chamber end face and fixing with it of horse; Described sealing ring is fixed in bell sealing ring and horse not between sealing ring.
Further, described sealing ring is silicone rubber O-ring.
Further, described bell sealing ring, horse not gathering sill and sealing ring are ring-type.
Further, the inner plane of described bell sealing ring is a smooth ramp.
Further, described horse not the lateral surface of gathering sill be a convex slope.
Further, the radius of described bell sealing ring is greater than the horse radius of gathering sill not.
Further, described horse not the radius of gathering sill less than the radius of sealing ring.
Further, described bell cooling chamber is bell water cooling chamber.
Further, described horse not cooling chamber be not water cooling chamber of horse.
The sealing device of a kind of new shaft furnace mouth that the utility model provides, its beneficial effect is: 1. horse not gathering sill be raised in horse not the cooling chamber end face can prevent the direct radiation of hot gas to silicone rubber O-ring in stove, extended the service life of sealing ring; 2. utilize the inclined-plane pressure of bell sealing ring and horse not the positioning action of gathering sill make sealing ring crimp, to fully sealing between body of heater and bell, strengthened sealing effectiveness by the shape after sealed ring deformation; 3. owing to adopting side seal, can avoid plane, sealing ring top because the ash that falls causes poorly sealed close defective.Thereby the contact-making surface that has thoroughly solved original flat seal is little, seal insecure operation problem, effectively improved the reliability and safety of equipment sealing.
Description of drawings
Fig. 1 is a kind of sealing device profile for the shaft furnace mouth of the utility model.
The specific embodiment
As shown in Figure 1, a kind of sealing device for the shaft furnace mouth comprises: bell cooling chamber 1, bell sealing ring 2, horse be not cooling chamber 5, bell 6 and Muffle furnace body 7 of gathering sill 3, sealing ring 4, horse not, and described bell cooling chamber 1 is fixed in bell 6 end faces; Described bell sealing ring 2 is fixed in bell 6 bottom edge; Described horse not cooling chamber 5 is fixed in the Muffle furnace body 7 tops outsides; Described horse not gathering sill 3 is fixed in not cooling chamber 5 end faces of horse; Described sealing ring 4 is fixed in bell sealing ring 2 and horse not between gathering sill 3.
When carrying out operation, not cooling chamber 5 is cooling in the space, up and down with horse for bell cooling chamber 1, protection silicone rubber O-ring 4 is avoided high temperature ageing, extend its service life, bell 6 in the rise and fall process by bell sealing ring 2 and horse gathering sill 3 guide-localizations not, accurately extruding silicone rubber O-ring 4 makes its compressive deformation form multidimensional seal, has guaranteed the reliability and safety of sealing, has effectively improved functional reliability and the chronicity of equipment; The periphery of silicone rubber O-ring 4 divides contact by the pressure filling of bell 6, the top and bottom of silicone rubber O-ring 4 have bell cooling chamber 1 and horse not cooling chamber 5 carry out coolingly, can prevent the ageing failure that silicone rubber O-ring 4 produces for a long time under the condition of high temperature.Bell sealing ring 2 not forms guide frame on gathering sill 3 circumference with horse, guarantee bell 6 in the decline process and between Muffle furnace body 7 accurate location sealing.
A kind of sealing device for the shaft furnace mouth that the utility model provides, utilize the inclined-plane pressure of bell sealing ring and horse not the positioning action of gathering sill make sealing ring crimp, by the shape after sealed ring deformation to fully sealing between body of heater and bell.The operation problems such as the contact-making surface that has solved original flat seal is little, sealing inaccuracy have effectively improved the reliability and safety of equipment sealing.
The above is only preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment, the utility model is had been described in detail, for a person skilled in the art, it still can be modified to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
