Description
Technical field
The technical field of aluminium liquid heating is the utility model is related to, particularly a kind of aluminum melt immersion heated by natural gas dress
Put.
Background technology
Aluminium liquid in the heat source way generally use Electric heating heating and thermal insulation stove of aluminium liquid holding furnace.Traditional electrical heating point
The heating of half impregnated is inserted for radiant type heating and top.Radiant heater makes aluminium liquid surface absorb heat by heat radiation, but
The aluminium liquid absorption thermal efficiency is low, heat absorption speed is slower, and aluminium liquid temperature control low-response, temperature control performance is poor, causes amount of heat to scatter and disappear, and wastes
Electric energy；In addition, aluminium liquid surface temperature it is high and and air contact, therefore the oxide of aluminium is more, need to frequently clear up.
Utility model content
The shortcomings that the purpose of this utility model is to overcome prior art, there is provided it is a kind of it is compact-sized, avoid producing aluminium
Oxide, the firing rate for improving aluminium, aluminium liquid temperature control respond fast aluminum melt immersion heated by natural gas device.
The purpose of this utility model is achieved through the following technical solutions：A kind of aluminum melt immersion heated by natural gas dress
Put, it includes furnace lining and heating tube, is loaded with aluminium liquid in the furnace lining, dividing plate is provided with the top of furnace lining, is provided with dividing plate
Two through holes, described heating tube include air inlet pipe, escape pipe and connecting tube, and air inlet pipe and escape pipe are plugged in two and led to respectively
Seal in hole and with through-hole wall and coordinate, connecting tube, air inlet pipe are communicated between the bottom of air inlet pipe and the bottom of escape pipe
Upper end be connected with natural gas combustion nozzle, the upper end of escape pipe is connected with waste gas outlet pipe.
Described air inlet pipe and the vertical setting of escape pipe.
Described dividing plate is fixed at the top of furnace lining through screw.
Described connecting tube takes the shape of the letter U shape.
Described furnace lining is circular, rectangle or ellipse.
The tube wall of described heating tube is 5 ~ 20mm.
The utility model has advantages below：The utility model is compact-sized, avoids producing the oxide of aluminium, improves aluminium
Firing rate, aluminium liquid temperature control response are fast.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of the utility model median septum；
In figure, 1- furnace linings, 2- dividing plates, 3- through holes, 4- air inlet pipe, 5- escape pipes, 6- connecting tubes, 7- natural gas combustion nozzles, 8-
Waste gas outlet pipe, 9- screws.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings, the scope of protection of the utility model be not limited to
It is lower described：
As shown in Figure 1 and 2, a kind of aluminum melt immersion heated by natural gas device, it includes furnace lining 1 and heating tube, described
Furnace lining 1 is circular, rectangle or ellipse, is loaded with aluminium liquid in furnace lining 1, the top of furnace lining 1 is provided with dividing plate 2, set on dividing plate 2
There are two through holes 3.As shown in figure 1, the material of described heating tube is carborundum combination silicon nitride or Sialon ceramics, heating tube
Tube wall is 5 ~ 20mm, and heating tube includes air inlet pipe 4, escape pipe 5 and connecting tube 6, and air inlet pipe 4 and escape pipe 5 are plugged in two respectively
Seal in individual through hole 3 and with the wall of through hole 3 and coordinate, connecting tube is communicated between the bottom of air inlet pipe 4 and the bottom of escape pipe 5
6, connecting tube 6 takes the shape of the letter U shape, and the upper end of air inlet pipe 4 is connected with natural gas combustion nozzle 7, and the upper end of escape pipe 5 is connected with waste gas and gone out
Mouth pipe 8.
Described air inlet pipe 4 and the vertical setting of escape pipe 5.Described dividing plate 2 is fixed on the top of furnace lining 1 through screw 9.Institute
Aluminium liquid is closed in furnace lining 1 by the dividing plate 2 stated, it is therefore prevented that aluminium liquid and air contact, further prevents aluminium liquid to become after the heating
Into oxide, cleaning process is added.
The course of work of the present utility model is as follows：Natural gas is passed through into natural gas combustion nozzle 7, natural gas combustion nozzle 7 will be natural
Gas is lighted, and heat caused by burning enters in heating tube, and heat heats heating tube, and heated heating tube is again to furnace lining 1
Interior aluminium liquid is heated, and because the whole the latter half of heating tube is immersed in aluminium liquid, directly can be heated inside aluminium liquid,
Heated compared to traditional on aluminium liquid surface, heat conducts to surrounding, and temperature of aluminum liquid responds faster, realizes the quick of aluminium liquid and adds
Heat；Waste gas caused by burning is under pneumatic pressure sequentially through air inlet pipe 4, connecting tube 6 and escape pipe 5 finally from waste gas outlet pipe simultaneously
8 discharges.
