Abstract
A kind of sealing device for shaft furnace mouthful, including：Bell cooling chamber, bell sealing ring, Muffle guide groove, sealing ring, Muffle cooling chamber, bell and Muffle body of heater, the bell cooling chamber are fixed on bell top surface；The bell sealing ring is fixed on bell bottom edge；The Muffle cooling chamber is fixed on the outside of Muffle body of heater top；The Muffle guide groove is fixed on Muffle cooling chamber top surface；The sealing ring is fixed between bell sealing ring and Muffle seal groove.The present invention provides a kind of sealing device for shaft furnace mouthful, make sealing ring crimp using the ramp pressure of bell sealing ring and the positioning action of Muffle guide groove, sealing effectiveness is enhanced, it is sufficiently sealed to being carried out between body of heater and bell by the shape after sealed ring deformation.The contact surface that solves original flat seal is small, sealing surface easily pollutes, seal the operation problem such as inaccurate, effectively increases the sealed reliability and safety of equipment.
Description
Technical field
Patent of the present invention is related to elevated-temperature seal technology, specifically refers to the Sealing Technology of shaft furnace fire door.
Background technology
Shaft furnace is in equipment operation, and bell need to often open lifting workpiece, and one kind had then been needed between Muffle and bell both
Tight and accurate sealing device.Conventional sealing device is pressed into the packing structure on Muffle face using the round steel on bell face,
Because contact surface is small, compression distance is shallow, frequently results in that bell is poorly sealed, and so air is likely to enter Muffle body of heater
In；Furnace gas is harmful to operating personnel and environment, and furnace gas leaks, and has a strong impact on production safety.
The content of the invention
The technical problem to be solved in the present invention overcomes existing defect to be reliably used for shaft furnace mouthful there is provided a kind of
Sealing device, the existing shaft furnace of solution is poorly sealed, the defect that furnace gas leaks.
A kind of sealing device for shaft furnace mouthful of the present invention, including：Bell cooling chamber, bell sealing ring, Muffle are oriented to
Groove, sealing ring, Muffle cooling chamber, bell and Muffle body of heater, the bell cooling chamber are fixed on bell top surface；The bell sealing
Ring is fixed on bell bottom edge；The Muffle cooling chamber is fixed on the outside of Muffle body of heater top；The Muffle guide groove is raised
In Muffle cooling chamber top surface and fixed thereto；The sealing ring is fixed between bell sealing ring and Muffle guide groove.
Further, the sealing ring is silicone rubber O-ring.
Further, the bell sealing ring, Muffle guide groove and sealing ring are ring-type.
Further, the inner plane of the bell sealing ring is a smooth ramp.
Further, the lateral surface of the Muffle guide groove is a convex slope.
Further, the radius of the bell sealing ring is more than the radius of Muffle guide groove.
Further, the radius of the Muffle guide groove is less than the radius of sealing ring.
Further, the bell cooling chamber is bell water cooling chamber.
Further, the Muffle cooling chamber is Muffle water cooling chamber.
A kind of sealing device for new shaft furnace mouthful that the present invention is provided, its advantage is：1. Muffle guide groove is raised
Direct radiation of the hot gas to silicone rubber O-ring in stove can be prevented in Muffle cooling chamber top surface, the use longevity of sealing ring is extended
Life；2. make sealing ring crimp using the ramp pressure of bell sealing ring and the positioning action of Muffle guide groove, pass through sealing
Shape after circle deformation is sufficiently sealed to being carried out between body of heater and bell, enhances sealing effectiveness；3. due to being sealed using side,
Sealing ring top plane poorly sealed close defect caused by falling ash can be avoided.So as to thoroughly solve the contact of original flat seal
Face is small, seal insecure operation problem, effectively increases the sealed reliability and safety of equipment.
Brief description of the drawings
Fig. 1 is a kind of sealing device profile for shaft furnace mouthful of the present invention.
Embodiment
As shown in figure 1, a kind of sealing device for shaft furnace mouthful, including：Bell cooling chamber 1, bell sealing ring 2, horse
Not guide groove 3, sealing ring 4, Muffle cooling chamber 5, bell 6 and Muffle body of heater 7, the bell cooling chamber 1 are fixed on bell 6 and pushed up
Face；The bell sealing ring 2 is fixed on the bottom edge of bell 6；The Muffle cooling chamber 5 is fixed on the outside of the top of Muffle body of heater 7；
The Muffle guide groove 3 is fixed on the top surface of Muffle cooling chamber 5；The sealing ring 4 is fixed on bell sealing ring 2 and Muffle guide groove
Between 3.
When carrying out operation, bell cooling chamber 1 is cooled down with Muffle cooling chamber 5 in space up and down, and protection silicone rubber O-ring 4 is kept away
Exempt from high temperature ageing, extend its service life, bell 6 passes through bell sealing ring 2 and Muffle guide groove 3 during rise and fall
Guide-localization, accurate extruding silicone rubber O-ring 4 makes its compressive deformation formation multidimensional seal, it is ensured that sealed reliability and peace
Quan Xing, effectively increases the functional reliability and chronicity of equipment；The pressure that the periphery of silicone rubber O-ring 4 passes through bell 6
Fully contact, the top and bottom of silicone rubber O-ring 4 have bell cooling chamber 1 to be cooled down with Muffle cooling chamber 5, can prevent silicon rubber
The ageing failure that sealing ring 4 is produced at high operating temperatures for a long time.Bell sealing ring 2 is oriented to being formed on the circumference of Muffle guide groove 3
Structure, it is ensured that bell 6 is accurately positioned sealing during decline between Muffle body of heater 7.
A kind of sealing device for shaft furnace mouthful that the present invention is provided, utilizes the ramp pressure and Muffle of bell sealing ring
The positioning action of guide groove makes sealing ring crimp, by the shape after sealed ring deformation to being filled between body of heater and bell
Divide sealing.The operation problem such as the contact surface that solves original flat seal is small, sealing is inaccurate, effectively increases equipment sealed
Reliability and safety.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, although with reference to foregoing reality
Apply example the present invention is described in detail, for those skilled in the art, it still can be to foregoing each implementation
Technical scheme described in example is modified, or carries out equivalent substitution to which part technical characteristic.All essences in the present invention
God is with principle, and any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
