Abstract
A muffle furnace is disclosed. The utility model relates to an improvement of a muffle furnace for high-temperature roasting, melting and incinerating treatment of samples in a laboratory, characterized in that door of the muffle furnace is provided with air vent holes; top part and back part of the furnace body are provided with air outlet holes through the furnace body. Since the door of the muffle furnace of the utility model is provided with air vent holes, various gases can be pumped in for purposes of accelerating oxidation, corrosion or protection of the samples under treatment of high-temperature roast, melt or incineration; in addition, gases harmful to the hearth and heating elements produced during the treatment process can be exhausted out from the air outlet holes, thereby prolonging the useful life of the heating elements.
Description
Technical field
A kind of Muffle furnace relates to a kind of improvement that is used in the laboratory sample being carried out high-temperature roasting, fusion, ashing processing Muffle furnace.
Background technology
Muffle furnace is mainly used in the laboratory sample is carried out high-temperature roasting, fusion, ashing processing etc.In order to reach good heat insulation effect, lower furnace door always closes in working order, is added with insulating brick toward contact.Owing to sample processed in stove, often to emit the gas that can damage burner hearth and heating element heater in a large number, because sealing better is difficult to emit, the result can cause a series of phenomenons generations that diminish stove such as the lifetime of heating element heater.Moreover when if processed sample needs to corrode under accelerated oxidation or the researching high-temperature oxidizing atmosphere, the aerating oxygen of also having no idea equally also has no idea to feed the processed sample of inert gas shielding.Can not satisfy the demand that kinds of processes requires.
Summary of the invention
The purpose of this utility model is the deficiency that exists at above-mentioned prior art; provide when a kind of energy is satisfied to carry out high-temperature roasting, fusion, ashing processing requirements to sample, can also feed all gases and reach the novel Muffle furnace that the requirement of sample kinds of processes is handled in accelerated oxidation, corrosion or protection.
The purpose of this utility model is achieved through the following technical solutions.
A kind of Muffle furnace, comprise the body of heater formed by flame retardant coating and heat insulation layer, be arranged on the temperature-time controller in described body of heater control room and be arranged on temperature sensor, fire door on the described body of heater, it is characterized in that: the fire door of Muffle furnace is provided with passage, and the top of body of heater and the rear portion of body of heater are provided with the venthole that runs through body of heater.
Muffle furnace of the present utility model, its feature are connected with the breather pipe of the valve of band on the passage that is provided with on the fire door, be connected with the escape pipe of the valve of band on the venthole that runs through body of heater that the top of body of heater and the rear portion of body of heater are provided with.
Muffle furnace of the present utility model; fire door is provided with passage; high-temperature roasting, fusion, ashing processing can be finished material; feed all gases and reach the purpose that sample is handled in accelerated oxidation, corrosion or protection; the infringement burner hearth that process produces and the gas of heating element heater; can discharge by the gas outlet, prolong the life-span of heating element heater.

Specific embodiments
A kind of Muffle furnace comprises the body of heater 1 be made up of flame retardant coating and heat insulation layer, is arranged on the temperature-time controller 3 in described body of heater control room 2 and is arranged on temperature sensor 4, fire door 5 on the described body of heater; The fire door of Muffle furnace is provided with passage 6, the gas outlet 7,8,9,10,11 of the bottom of body of heater, the gas outlet 12,13,14,15 at body of heater rear portion and the gas outlet 16,17,18,19,20 at body of heater top.And on the passage that is provided with on the fire door, be connected with the breather pipe 21 of the valve of band, be connected with the escape pipe 22 of the valve of band on the venthole that runs through body of heater that the rear portion of the bottom of body of heater, top and body of heater is provided with.
The flow velocity of gas can be controlled by valve, and the flow direction of gas can be adjusted by different gas vents.And be furnished with in each outlet and can control the valve that gas is derived.If allow gas flow freely, can open the valve of a plurality of outlets.
21 23 is heating element heater among the figure.
The accelerated oxidation metal fragment, at 800 ℃ of following aerating oxygens, the valve that opening the control gas in all gas outlet derives flows freely by gas.So not only shortened the evenly thorough of oxidization time but also oxidation.
Aluminium nitride is 600～700 ℃ of following aerating oxygen decarburizations 2 hours, and the valve that opening the control gas on the gas vent 12,13,14,15 at rear portion derives flows by gas transverse.Obtain the aluminium nitride powder of grey at last.The powder phosphorus content that has not only shortened decarburization time but also obtained at last also significantly reduces.
Claims (2)
1. Muffle furnace, comprise the body of heater formed by flame retardant coating and heat insulation layer, be arranged on the temperature-time controller in described body of heater control room and be arranged on temperature sensor, fire door on the described body of heater, it is characterized in that: the fire door of Muffle furnace is provided with passage, and the top of body of heater and the rear portion of body of heater are provided with the venthole that runs through body of heater.
2. according to wanting profit to require 1 described Muffle furnace, its feature is connected with the breather pipe of the valve of band on the passage that is provided with on the fire door, be connected with the escape pipe of the valve of band on the venthole that runs through body of heater that the top of body of heater and the rear portion of body of heater are provided with.
