Specific embodiment
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments:
A kind of spiral inner wall crucible furnace shown in Fig. 1 and Fig. 3, including furnace body 1, the furnace body 1 are built into column by refractory material,
Its outside passes through iron sheet and wraps up；The furnace body 1 is provided centrally with open-topped burner hearth 9, and crucible 6, institute are placed in burner hearth 9
The bottom for stating crucible 6 passes through the support of crucible seat stand 11 that 9 bottom centre of burner hearth is arranged in, and the top of crucible 6 is by being arranged in furnace
The gland 2 at 1 top of body is fixed, while being sealed by gland 2 to burner hearth 9, and the center of the gland 2 offers and earthenware
What is communicated inside crucible 6 takes soup mouth 7, and 1 outside of furnace body is provided with flame hole 4, the end of the flame hole 4 close to the position of bottom
Face is provided with the convergence hole 10 being connected to burner hearth 9, and burner 3 is equipped in convergence hole 10, and the burner 3 is energy saving burner；Institute
The interior helical guide groove 12 being provided with along its wall surface from bottom to top of burner hearth 9 is stated, if the helical guide groove 12 is by xeromenia alumina material
Guide block made of prefabricated builds forming；9 wall surface of burner hearth above helical guide groove 12 is internally provided with vertical exhaust passage
8, the top of the exhaust passage 8 is connected to burner hearth 9, and end is connected to convergence hole 10, and the exhaust passage 8 is connected to the top end of burner hearth 9
Mouth is in flared, and the end of exhaust passage 8 is corresponding with 3 end of burner being located in convergence hole 10.
The hot solution in crucible is leaked in order to prevent causes damages into not being discovered in burner hearth 9, the bottom surface of the burner hearth 9
With inclination angle, which connect with the leak detection alarm mouth 5 that 1 outside of furnace body is arranged in.
As shown in Fig. 2, the leak detection alarm mouth 5 is made of detection mouth 51 and cover board 52, outside the detection mouth 51
End face is oblique, and two sides are provided with symmetrical hook 53, and the both ends of the cover board 52 are provided with symmetrical extension
Bar 54, cover board 52 is hung on hook 53 by hanging rod 54, and the top of the cover board 52 is provided with handle 55.
As shown in figure 4, the detection mouth 51 protrudes the outside for being fixed on furnace body 1, end, which is provided with, lets out soup hole 57, described
The bottom surface lowest part of the inner end connection burner hearth 9 in soup hole 57 is let out, is communicated outside outer end and furnace body 1, soup is being let out in the setting of cover board 52
The outer end in hole 57 is blocked to the closing of soup hole 57 is let out；The top of the detection mouth 51 is provided with metal electrode pipe 56, the metal
The top of electrode tube 56 is electrically connected with the electrical cabinet for connecting alarm, and end passes through detection mouth 51 and extends in and lets out in soup hole 57；
The metal electrode pipe 56 has two, convenient for conduction.
Its working principles are as follows: aluminium is put into crucible 6 by taking crucible aluminum melting as an example, burner 3 generates flame, and flame is suitable
The helical guide groove 12 for prolonging 9 inner wall of burner hearth is crept up around the outer wall of crucible 6 in the shape of a spiral, and is evenly heated to crucible 6,
Hot melt takes soup mouth 7 to take out at aluminium soup on aluminium Tang Kecong gland 2 after aluminium in crucible 6 is heated, and be poured in next step plus
Work；Meanwhile the exhaust gas after flame combustion is again fed at burner 3 by exhaust passage 8, is burnt since burner 3 belongs to energy saving
Mouth by waste gas absorption and can be discharged.After if the aluminium soup in crucible 6 is leak into burner hearth 9, because 9 bottom of burner hearth has certain inclination angle,
The aluminium soup of leakage, which can flow into, to be let out in soup hole 57, after letting out the aluminium rushing face contact in soup hole 57 to two metal electrode pipes 56, by
Conductive in aluminium, the series connection of two metal electrode pipes 56 is powered, so that electric signal is delivered to electrical cabinet, and by with electricity
The connected alarm of gas holder is alarmed, to facilitate staff that can discover in time, is cut off the work of crucible furnace, is excluded event
Barrier reduces loss.
This spiral inner wall crucible furnace is forced to increase the circumference number of flame by helical guide groove 12, so that crucible 6 is whole
It can be wrapped up by flame, heat improves 6 heat efficiency of crucible to the whole transmitting of crucible 6, so that solution rate is promoted, and crucible 6
Surface loading become uniform, it is therefore prevented that crucible 6 certain portion apply localised load so that the service life of crucible 6 is improved, separately
Outside, the temperature unevenness of hot melt liquid disappears in crucible 6, and upper and lower temperature is uniform, and then is associated with the stabilization of casting property, subtracts
The fraction defective for having lacked product can recycle waste heat exhaust, improve energy by the combination of exhaust passage 8 and Energy saving burning nozzle
Source cycle efficieny, reaches energy-saving effect, while the design of leak detection alarm mouth 5 is so that the safety coefficient of crucible furnace and use the longevity
Life is improved and extends.
