The specific embodiment
For further disclosing technical scheme of the present invention, be hereby described with reference to the accompanying drawings embodiments of the present invention.
Fig. 1 is the overall structure schematic diagram of improved melting furnace of the present invention, the internal structure schematic diagram that Fig. 2 is improved melting furnace of the present invention, and the melting furnace shown in figure comprises: body of heater 10; Melting channel 15, the top that it is positioned at the inside of described body of heater 10 and is opened on body of heater 10, this melting channel 15 is for carrying out heat fused to raw material metal; In addition, this melting furnace also comprises: material-pouring device 20, and it is fixed on the sidewall of described body of heater 10, and its inner chamber is connected with described melting channel 15, more specifically, the longitudinal section of described material-pouring device 20 is that right-angled trapezium is that the inner chamber of material-pouring device 20 is a right-angled trapezium body; Material-pouring device outlet 22, its be arranged at described material-pouring device 20 bottom and with the intracavity inter-connection of described material-pouring device 20, when melting furnace carries out batch turning, molten metal exports 22 by material-pouring device again and flows out after melting channel 15 flow in material-pouring device 20, thereby can control accurately the route that molten metal is flowed through.
In addition, in order to reach insulation and heat insulation effect, on the inwall of described melting channel 15, build and have four layers of heat-barrier material, these four layers of heat-barrier materials are followed successively by from outside to inside: casting material brick 14, ramming mass 13, insulating brick 12 and asbestos board 11; The inwall of described material-pouring device 20 is built refractory brick 21.
In order further to increase insulation and the effect of heat insulation of melting furnace, this melting furnace also comprises: melting channel insulation cover, its for the opening that hides described melting channel 15 to play insulation effect; And material-pouring device insulation cover 30, it is for hiding the opening of described material-pouring device 20.Wherein, as shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, described material-pouring device insulation cover 30 comprises: handle 33; Screw rod 32, it is fixedly connected with described handle 33; Spiro rod cap 31, screw thread is carved with in its inside, and described screw rod 32 can screw in this spiro rod cap 31 and from the other end of this spiro rod cap 31 and pass; Draw-in groove 34, it is fixedly connected with described screw rod 32 lower ends, and its both sides are provided with screwed hole; A pair of screw 35, this can screw in the screwed hole of described draw-in groove 34 both sides to screw 35; Graphite rod 40, the top 41 of this graphite rod 40 can be stuck in described draw-in groove 34 and be about to this graphite rod 40 and be connected on described screw rod 32 by described a pair of screw 35, in addition, this graphite rod 40 can insert in described material-pouring device outlet 22 and prevent molten metal outflow to seal this material-pouring device outlet 22.
Two kinds of action situations while disclosed improved melting furnace work being described below in conjunction with accompanying drawing.
Step in action situation one is followed successively by: 1. raw material metal melts in described melting channel 15; 2. during batch turning, the molten metal after fusing finally flows out by described material-pouring device outlet 22 after described melting channel 15 flow in described material-pouring device 20 again, thereby can control accurately the route that molten metal is flowed through.Meanwhile, the inwall of described material-pouring device 22 is built refractory brick 21, can play insulation effect to the molten metal in this material-pouring device 20.
Step in action situation two is followed successively by: 1. raw material metal melts in described melting channel 15; 2. described in, the top 41 of graphite rod 40 is stuck in described draw-in groove 34 and is about to this graphite rod 40 and is connected on described screw rod 32 by described a pair of screw 35; 3. described material-pouring device insulation cover 30 is covered to the opening of described material-pouring device 20, now described graphite rod 40 is inserted in described material-pouring device outlet 22 and prevents molten metal outflow to seal this material-pouring device outlet 22; 4. during batch turning, molten metal after fusing is constantly flow in described material-pouring device 20 by melting channel 15, when the molten metal in described material-pouring device 20 reaches a certain amount of, swing handle 33 moves up described screw rod 32, thereby drive described graphite rod 40 to leave described material-pouring device outlet 22, now molten metal finally flows out by described material-pouring device outlet 22, thereby can control accurately the route that molten metal is flowed through.Equally, because the inwall of described material-pouring device 20 is built, there is refractory brick 21, can play to the molten metal in material-pouring device 20 better insulation effect.
