Description

A kind of melting and heat preservation stove

Technical field

The utility model relates to a kind of melting and heat preservation stove, particularly relates to a kind of non-ferrous metal melting holding furnace that is replaced former refractory fireclay block by aluminosilicate refractory fiber felt.

Background technology

Melting furnace is widely used heat energy utilization equipment in industrial production.According to Heating style, melting furnace can be divided into Fuel Furnace and the large type of electric furnace two.China present stage a large amount of Fuel Furnace of using, its shortcoming is that efficiency of combustion is low, fuel storage is inconvenient, gas and liquid fuel are easily blasted and combustion noise etc.Electric furnace be take resistance wire furnace as main, and its major defect is resistance wire easy fracture, and service life is short, maintenance difficult, and the low and heat-insulating property of the thermal efficiency is poor etc.

General electric furnace has three parts to form, i.e. heater element, furnace building material and control device.The shortcoming existing for current resistance wire furnace, has carried out omnibearing transformation, and the utility model relates to a kind of heat insulating material of resistance wire furnace, with alumina silica refractory, replaces refractory fireclay block.

The furnace building material refractory fireclay block of old-fashioned melting furnace, heat has 35%-40% to lose by furnace wall, and Here it is, and this kind of stove firing rate is slow, the reason that heat-insulating property is poor, the thermal efficiency is low.We have selected novel heat-insulating material---aluminosilicate refractory fiber felt.This material thermal conductivity is little, and amount of stored heat is little, light specific gravity, and thermal shock resistance is good, flexible, the advantage that chemical stability is good.Therefore, can shorten the heating-up time of stove as furnace building material, reduce temperature of furnace lining, dwindle stove overall dimensions, due to outer surface with to reduce the little thermal loss of area of dissipation little, 25%-35% can economize on electricity.

As can be seen here, above-mentioned existing melting and heat preservation stove, in structure and use, obviously still has inconvenience and defect, and is urgently further improved.Therefore how to found a kind of melting and heat preservation stove of new structure, also becoming the current industry utmost point needs improved target.

Because the defect that above-mentioned existing melting and heat preservation stove exists, the inventor is based on being engaged in this type of product design manufacture abundant practical experience and professional knowledge for many years, and the utilization of cooperation scientific principle, positive research and innovation in addition, to founding a kind of melting and heat preservation stove of new structure, can improve general existing melting and heat preservation stove, make it have more practicality.Through constantly research, design, and after repeatedly studying sample and improving, finally create the utility model having practical value.

Summary of the invention

The purpose of this utility model is, overcomes the defect that existing melting and heat preservation stove exists, and a kind of melting and heat preservation stove of new structure, technical problem to be solved are provided, is to make it with aluminosilicate refractory fiber felt, replace refractory fireclay block, is very suitable for practicality.

The purpose of this utility model and solve its technical problem and realize by the following technical solutions.According to a kind of melting and heat preservation stove the utility model proposes, comprising: base, pillar, power chain fishplate bar, mains connection, furnace wall, aluminosilicate refractory fiber felt, power switch, wherein: on described base, be connected with pillar, pillar top is connected with described power chain fitting, and is arranged at inside, furnace wall; On the inner surface of described furnace wall, be installed with described aluminosilicate refractory fiber felt.

The purpose of this utility model and solve its technical problem and also can be applied to the following technical measures to achieve further.

Aforesaid a kind of melting and heat preservation stove, is characterized in that described furnace wall is arch.

Aforesaid a kind of melting and heat preservation stove, is characterized in that described aluminosilicate refractory fiber felt is trapezoidal, and by upper base, the alternately docking of going to the bottom, is fixedly arranged in order the inner surface of described furnace wall.

Aforesaid a kind of melting and heat preservation stove, is characterized in that being provided with described mains connection on described power chain fishplate bar.

Aforesaid a kind of melting and heat preservation stove, is characterized in that described furnace wall outer setting has power switch, and is connected with mains connection.

The utility model compared with prior art has obvious advantage and beneficial effect.As known from the above, for achieving the above object, the utility model provides a kind of melting and heat preservation stove, comprise: base, pillar, power chain fishplate bar, mains connection, furnace wall, aluminosilicate refractory fiber felt, power switch, wherein: on described base, be connected with pillar, pillar top is connected with described power chain fitting, and is arranged at inside, furnace wall; On the inner surface of described furnace wall, be installed with described aluminosilicate refractory fiber felt.

General electric furnace has three parts to form, i.e. heater element, furnace building material and control device.The utility model relates to a kind of heat insulating material of resistance wire furnace, with alumina silica refractory, replaces refractory fireclay block.The furnace building material refractory fireclay block of old-fashioned melting furnace, heat has 35%-40% to lose by furnace wall, and Here it is, and this kind of stove firing rate is slow, the reason that heat-insulating property is poor, the thermal efficiency is low.

By technique scheme, a kind of melting and heat preservation stove of the utility model at least has following advantages and beneficial effect: selected novel heat-insulating material---aluminosilicate refractory fiber felt.This material thermal conductivity is little, and amount of stored heat is little, light specific gravity, and thermal shock resistance is good, flexible, the advantage that chemical stability is good.Therefore, can shorten the heating-up time of stove as furnace building material, reduce temperature of furnace lining, dwindle stove overall dimensions, due to outer surface with to reduce the little thermal loss of area of dissipation little, 25%-35% can economize on electricity.
