Abstract
The utility model relates to a sealing device with a telescopic muffle arranged on well furnace, comprising a furnace shell, a air duct, a heating element, a base, a bed of furnace and a frame for oil, wherein the bed of furnace is disposed on the base, the frame and the air duct are positioned on the bed of furnace, the heating element is installed on the furnace shell, and a tubular muffle and a corrugated pipe are included further. The tubular muffle is disposed on the furnace shell and fixed to the inner side of the heating element, the lower end of the tubular muffle is connected with the upper end of the corrugated pipe firmly, thereby composing an integral, and the lower end of the corrugated pipe is fixed to the bottom surface of the base. With the configuration of the corrugated pipe, the distortion caused by heat expansion of the muffle on work is compensated, thereby saving oil sealing, preventing the probable accident yield by oil sealing, simplifying the manufacture of carburizing furnace and nitriding furnace and making maintenance and manipulation convenient, safe and reliable.
Description
Technical field
The utility model relates to a kind of thermal treatment unit, refers in particular to a kind of Muffo telescopic sealing equipment of shaft furnace.
Background technology
At present well formula carburizing or carbonitriding stove and well formula nitriding furnace separate for the carburizing in the stove or nitriding atmosphere and heating unit on every side, in case these atmosphere work the mischief to heating unit, in stove, be provided with horse not, to guarantee that stove can works better, horse sealing not is one of gordian technique of this class Equipment for Heating Processing, horse not is suspended on top in the work, insert in the annular sealing oil groove horse lower end not, and workpiece is placed on the bottom of stove, and horse is not at the after that is heated, the post shrinkage of catching a cold, the degree of depth of sealing oil groove is enough to the displacement that guarantees that horse is not expanded with heat and contract with cold and causes, and this horse tightness system not in use is heated sealing oil and produces volatilization, oil mass reduces, and seal failure, it needs quantitative check and maintenance, when the obstruction of stove inside exhaust pipe road is broken down, cause that very easily furnace pressure is too high, sealing oil in the sealing oil groove can spray outside the groove, causes seal failure, and working gas overflows burning in the stove, cause body of heater to catch fire outward, even lead to Serious Accident.
Summary of the invention
The purpose of this utility model is to provide a kind of Muffo telescopic sealing equipment of shaft furnace, pass through the technical program, horse can carry out not only not that heat expansion is cool to contract with the situation of temperature, and can therefore not leak the working gas in the stove, to remedy defective and the deficiency that exists in the prior art.
The technical scheme in the invention for solving the above technical problem is: a kind of Muffo telescopic sealing equipment of shaft furnace, it comprises stove outer covering, ventilating duct, heating unit, base, furnace bottom and bin, described furnace bottom is arranged on the base, furnace bottom is provided with bin and ventilating duct, be provided with heating unit in the described stove outer covering, it also includes the tubular horse not and corrugated tube, described tubular horse not is arranged on stove outer covering and the heating unit inboard that is fixed on the stove outer covering, tubular horse lower end and corrugated tube upper end not is connected to one, and the lower end of its corrugated tube is fixed on the baseplane of base.
Described tubular horse lower end not is positioned at the below of furnace bottom.
Be provided with flame-proof thermal insulation material in the described stove outer covering, the furnace bottom at furnace bottom position and horse not between and between Ma Fu and the stove outer covering inwall sealing is set.
Described at the furnace bottom position furnace bottom and horse not between and be provided with between Ma Fu and the stove outer covering inwall be sealed into the ceramic fiber sealing.
The related Muffo telescopic sealing equipment of shaft furnace beneficial effect of the utility model is: pass through the technical program, adopt corrugated tube to compensate the not distortion that brings of expanded by heating at work of horse, save oil seal, stopped the accident potential that might occur because of oil seal, thereby make the manufacturing of cementing furnace and nitriding furnace simpler, safe and reliable, make its maintenance and more convenient to operate.
