Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, a novel energy-saving crucible furnace structure includes: furnace body 1 and base 2, furnace body 1 and base 2 fixed connection, the outer wall fixedly connected with exhaust duct 3 of furnace body 1, exhaust duct 3 and furnace body 1 UNICOM, so that discharge fume, and exhaust duct 3 is low thermal conductivity material, so that reduce the heat and scatter and disappear, the outer wall fixedly connected with cartridge heater 4 of exhaust duct 3, cartridge heater 4 is ceramic cartridge heater, ceramic thermal conductivity is low, it is effectual to resist heat, so as to avoid reducing the furnace temperature when passing through furnace body 1 is inside, the inside of cartridge heater 4 is provided with air inlet tube 5, air inlet tube 5 is the metal air inlet tube, so that transmit the inside temperature of cartridge heater 4 to air inlet tube 5 fast, conveniently heat the air, the outer wall fixedly connected with intake pipe 6 of air inlet tube 5.

Wherein; the inner wall of the furnace body 1 is movably connected with a furnace bridge 7, and the top of the furnace body 1 is provided with a crucible 8, so that the inside is ventilated and materials are heated.

Wherein; the inner wall threaded connection of exhaust duct 3 has connecting cylinder 9, and the one end that connecting cylinder 9 is close to furnace body 1 is provided with filter screen 10 to in with the large granule interception, and the small granule of adhesion portion, avoid exhaust duct 3 to block up.

Wherein; storage cavity 11 has been seted up to base 2's inside, and base 2's inner wall sliding connection has ash collection steamer tray 12, and the shape size of ash collection steamer tray 12 and the shape size of storage cavity 11 all match each other, through storage cavity 11 and ash collection steamer tray 12 that set up, be convenient for collect the furnace ash and concentrate, directly take out ash collection steamer tray 12 when convenient clearance, improved cleaning efficiency and convenience.

Wherein; the exhaust hole is opened in the side that adds heat cylinder 4 and is close to collection ash steamer tray 12, and the inner wall in exhaust hole and the outer wall fixed connection of intake pipe 6, the output of intake pipe 6 is down to avoid air inlet cylinder 5 to be blockked up by the ashes that the stove dropped.

Wherein; one end of the air inlet cylinder 5 penetrates through the inner wall of the exhaust pipeline 3 and extends to the outer wall of the exhaust pipeline 3, the inner part of the exhaust pipeline 3 is communicated with the inner wall of the heating cylinder 4, and the air inlet end of the air inlet cylinder 5 is opposite to the exhaust end of the heating cylinder 4 in direction, so that waste gas is prevented from entering the air inlet cylinder 5 to reduce oxygen content.

The working principle is that when in use, the waste gas with residual heat enters the exhaust pipeline 3 and is blocked by the filter screen 10 in the first bend to block large-particle dust, then the waste gas enters the heating cylinder 4, the temperature of the waste gas in the heating cylinder 4 is higher than the temperature of the air entering the air inlet cylinder 5, the air in the air inlet cylinder 5 is heated by the heat conduction of the air inlet cylinder 5, the temperature reduction in the furnace is reduced, the fuel waste is indirectly reduced, the air heated in the air inlet cylinder 5 enters the furnace body 1 through the air inlet pipe 6 after the temperature in the heating cylinder 4 is reduced, so that the fuel in the furnace body 1 is burnt, because the heat conduction efficiency of the exhaust pipeline 3 and the heating cylinder 4 is low, the heat preservation effect to inside waste gas is better, and the stove is lower to exhaust duct 3 and heating cylinder 4's heating efficiency simultaneously, and the heat that carries when waste gas discharges reduces.
