For making goal of the invention of the present utility model, feature, the advantage can be the most obvious and understandable, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, the embodiments described below are only a part of embodiment of this utility model, and not all embodiments.Based on the embodiment in this utility model, the every other embodiment that those skilled in the art is obtained, broadly fall into the scope of this utility model protection.
Term " first " in specification and claims of the present utility model and above-mentioned accompanying drawing, " second " etc. are for distinguishing similar object, without being used for describing specific order or precedence.Should be appreciated that the term of so use can exchange in the appropriate case, this only describes the differentiation mode used the object of same alike result when describing in embodiment of the present utility model.In addition, term " includes " and " having " and their any deformation, it is intended to cover non-exclusive comprising, to comprise the process of a series of unit, method, system, product or equipment to be not necessarily limited to those unit, but can include the most clearly listing or for intrinsic other unit of these processes, method, product or equipment.
It is described in detail individually below.
Specifically, as it is shown in figure 1, this utility model includes combustion system 5 without the energy-conservation metallurgical furnace of scaling loss (herein for aluminium melting furnace), firing chamber 6 connects with firing chamber 6 charging chamber 9, eddy current well 7 and automatic feeder 1；Wherein, the top of firing chamber 6 is divided into the combustor including heat smoke (also can contain flame)；In firing chamber 6, the liquid level of high temperature fluent metal 13 uses heat transfer brick 12 by the high-temperature flue gas isolation of high temperature fluent metal 13 with firing chamber 6 upper part；Separated by partition wall 10 between the upper part of firing chamber 6 and charging chamber 9, containing oxygen in the high-temperature flue gas of firing chamber 6 upper part, by the high-temperature flue gas of high temperature fluent metal 13 with firing chamber 6 upper part is isolated, to prevent the oxidation (scaling loss) of metallic aluminium；It is provided with a submersible type between charging chamber 9 and automatic feeder 1 to feed intake entrance 2.
Wherein, described heat transfer brick 12 be thermal radiation absorption than high heat conduction refractory material, be divided into upper, middle and lower three layers, middle level is solid, being densely covered with the aperture as labyrinth of intercommunication inside levels, the aperture on upper strata can also make cellular or ant nest shape, and fin can be made by lower floor；In this utility model embodiment, labyrinth-like aperture is made on upper strata, and fin is made by lower floor；The density of material of described heat transfer brick 12 is less than the density of liquid metal, and material thermal radiation absorption ratio is high, improves heat transfer brick 12 and absorbs the ability of radiant heat transfer；As a example by aluminum, in metallurgical furnace, the blackness due to aluminum is the lowest, thermal radiation absorption ratio the lowest (less than 0.2), and heat transfer rate can be improved 2-5 times by this utility model.The aperture as labyrinth of the internal intercommunication of gathering in heat transfer brick 12 upper strata, adds the convection heat transfer' heat-transfer by convection speed of heat smoke and heat transfer brick 12, can improve several times to tens times.The thickness of described heat transfer brick 12 is 1cm-20cm, is 2cm in this utility model embodiment；Integrating, the heat transfer speed between heat smoke and liquid aluminium can be improved several times by this utility model, accelerates the programming rate of metal, shortens smelting time, saves energy resource consumption.Liquid metal is immersed in described heat transfer brick 12 lower floor, and according to the heat output computing formula of conduction of heat, the heat transfer rate between heat transfer brick 12 and liquid metal will tend to infinitely great.The several times even hundreds times heat that brick 12 absorbs so conducting heat in this utility model, can quickly be conducted to high temperature fluent metal 13 completely.Wherein, flame arrow 1A indication along burner 11 enters firing chamber 6, the heat smoke that flame produces produces downwards convection heat transfer' heat-transfer by convection with heat transfer brick 12, and heat transfer brick 12 absorbs the heat of high-temperature flue gas and carries out conduction of heat through arrow 2A direction, heats liquid metal 13；Meanwhile, produce infrared ray after the furnace roof body of wall on furnace wall side and top is heated and along arrow 3A, heat is invested the brick 12 that conducts heat with radiation mode.
The feed intake top of entrance 2 of described submersible type is slightly above liquid aluminum design height；The described submersible type base plane of entrance 2 that feeds intake is θ with the angle in the direction that feeds intake, wherein, and tan θ < fQuiet, and tan θ is more than close to fDynamic.Wherein, fDynamic、fQuietIt is respectively solid metallic 16 and the coefficient of kinetic friction of base plane and confficient of static friction.This utility model embodiment is arranged such described angle, to ensure that solid metallic 16 is when landing enters in liquid metal 14, speed will not be too fast and cause liquid metal 14 to splash, and destroys the oxide layer on liquid metal 14 surface in charging chamber 9, prevents new burning (scaling loss).Solid metallic 16 fusion process all slips in liquid metal 14, also will not produce oxidation (scaling loss).
During use, during blow-on, first put into enough solid metallics to firing chamber 6 from the second fire door 4；Starting combustion system 5 and to the METAL HEATING PROCESS in firing chamber 6 and be warmed up to the high temperature set, at this moment all there are liquid metal in firing chamber 6, eddy current well 7, charging chamber 9；Charging chamber 9 is formed on liquid metal face oxide film protection metal will not reoxidize；Then put into heat transfer brick 12 from the second fire door 4 to will heat up the liquid metal of room 6 and all cover, liquid metal 13 in firing chamber 6 is rapidly heated by the oxygen-containing heat smoke that at this moment combustion system 5 is sent into by heat transfer brick 12 augmentation of heat transfer (2 times when heat transfer rate is not conduct heat brick covering with up to decades of times), liquid metal 13 is immersed in heat transfer brick 12 lower floor, middle level is in close contact the liquid metal 13 covered in firing chamber 6, prevents from causing burning (scaling loss)；Starting mixing pump 8, liquid metal circulates from firing chamber 6 → eddy current well 7 → charging chamber 9 → firing chamber 6；Start automatic feeder 1, no longer feed intake from the second fire door 4；At this moment the solid metallic 16 in hopper 1-1 is delivered to the entrance of submersible type dog-house 2 by conveyer belt 1-2 according to the slower speed set, owing to submersible type dog-house 2 base plane meets along gradient θ in the direction that feeds intake: 1), tan θ < fQuiet, 2), tan θ is more than close to fDynamic, solid metallic 16 can slowly slip in the liquid metal 14 of charging chamber 9；Solid metallic 16 absorbs the heat melts of liquid metal 14, and fusion process does not has touch opportunity with oxygen, does not the most cause burning (scaling loss)；Liquid metal after solid metallic 16 fusing flows into firing chamber 6 and is warmed；So circulation, completes metal smelt.
Oxidization burning loss during metal smelt can be reduced to close to zero by this utility model, simultaneously the most energy-conservation in terms of three below: 1) in firing chamber 6 top half fuel combustion produce the heat of heat smoke and pass to the latter half and be heated the heat transfer intensity of metal and bring up to twice with up to decades of times, directly result in exhaust gas temperature reduction minimizing thermal loss, metal programming rate is accelerated to shorten fuel combustion time, produces obvious energy-saving effect；2) submersible type dog-house upper design becomes more slightly higher than setting metal bath surface, prevents the spilling of steam in charging chamber；3) automatic feeder feeds intake and decreases the door opened time, is used for preheating solid metallic 16 by a small amount of steam overflowed from submersible type dog-house simultaneously.
