Description

A kind of Muffle furnace

Technical field

This utility model is related to field of metallurgy, more particularly, to a kind of Muffle furnace.

Background technology

Muffle furnace is a kind of conventional smelting equipment, and Muffle furnace is from English " Muffle furnace " translation. " Muffle " is the meaning of parcel, and " furnace " is stove, the meaning of smelting furnace, and two words just constitute Muffle furnace together with arriving, English and the stove of chest parcel pattern, Muffle furnace is also called high-temperature electric resistance furnace, cabinet-type electric furnace in China, is a kind of general heating Equipment, Muffle furnace is made determination of elemental analysis and typically small-sized steel part quenching, is moved back mainly for laboratory, industrial and mining establishment, R＆D institution The heating during heat treatments such as fire, tempering is used, and high temperature furnace also can be used as the high-temperature heatings such as metal, the sintering of pottery, dissolving, analysis, powder End metallurgy continuous sintering Muffle furnace be made up of heating furnace body, temperature-controlling system, cooling system, have continuous sintering, stable temperature control, Easy to operate the features such as.

Existing metallurgy Muffle furnace, using arranging burning rack in burner hearth, slag charge is placed on opening and closing fire door on burning rack and exists Produce steam in furnace chamber and indirectly heat is carried out to the slag charge in burner hearth it is generally the case that the slag carrying out roasting is all through peracid The slurry changed, not only can form fast after being heated, once and temperature control is not good leads to temperature to cross high oxidation, so that slag charge surface is formed Oxide layer, is unfavorable for that the recovery of gas makes roasting not exclusively, needs multiple repeated calcination, and it is inefficient to accordingly, there exist roasting, The low defect of yield.

Utility model content

For deficiency of the prior art, this utility model provides a kind of Muffle furnace, in roasting process, improves roasting Spend completely, the energy effectively save time, improve production efficiency.

To achieve these goals, this utility model employs following technical scheme and is addressed：A kind of Muffle furnace, bag Include body of heater, in described body of heater, be provided with furnace chamber, in described furnace chamber, be provided with burner hearth, described burner hearth left and right sides wall is provided with many The telescopic cross bar of root, on described cross bar, equal spacing is provided with multiple spiral blades, and it is horizontal that described cross bar root is provided with storage The containing cavities of bar, the left cross bar top on left side wall is provided with draw-in groove, and the right cross bar top that right side wall stretches out is provided with dop, Described dop by described draw-in groove make left cross bar and right cross bar card and.

It is preferred that the position height of described left cross bar is corresponded with the position height of right cross bar in such scheme.

It is preferred that described telescopic cross bar includes 3～5 left cross bars and 3～5 and left cross bar pair in such scheme The right cross bar answered.

It is preferred that when the spiral blade on described cross bar is collapsible into containing cavities in such scheme, during blade with cross bar is The heart is gathered.

In such scheme it is preferred that described cross bar position is corresponding with the burning rack of setting in burner hearth.

It is preferred that described burner hearth is internally provided with the drive mechanism for making cross bar rotate in such scheme.

Compared with prior art, this utility model has the advantages that：It is provided with the wall of the described burner hearth left and right sides Many telescopic cross bars, cross bar root is provided with the containing cavities of storage cross bar, and after the completion of roasting, cross bar withdraws, and is easy to fire Buck takes out from burner hearth, and convenient and swift, on described cross bar, equal spacing is provided with multiple spiral blades, in roasting process, leads to Cross cross bar and drive blade rotation, the slag charge on burning rack is turned, not only can form fast after so that slag charge is heated, also can make stove After interior temperature anomaly leads to temperature too high slag charge surface to form oxide layer, oxide layer is crushed, is conducive to the volatilization of gas, makes roasting Burn more completely it is not necessary to multiple repeated calcination, obtain roasting improved efficiency, the high advantage of yield.
