Abstract
The utility model discloses a safe energy-gas-conservation high-temperature electric resistance furnace comprising a furnace top, silicon molybdenum rod heating elements, a furnace wall, a furnace bottom, a push plate, a crucible and a gas inlet pipe, wherein a closed furnace body is formed by the furnace top, the furnace wall and the furnace bottom; the silicon molybdenum rod heating elements are fixed in the furnace body and are respectively arranged at the upper parts of two sides of the furnace body; the push plate is arranged in the furnace body and is arranged on the furnace bottom; and the crucible is arranged on the push plate. In the electric resistance furnace, superior alumina is adopted as a working material for manufacturing a hearth capable of working stably within 1000 DEG C to 1600 DEG C, materials are fired at a high temperature to meet needed requirements according to the materials on the premise that the content of gas meets requirements, hydrogen and nitrogen are injected, and normally, the hydrogen is about 5%, while the nitrogen is about 95%, so that the hydrogen content can be controlled to be within an explosion limit range so as to realize the aim of safe operation, and the controllable furnace atmosphere and the stable furnace temperature are the grantee for enhancing and stabilizing the quality of products.
Description
Technical field:
The utility model relates to the high-temperature electric resistance furnace of the energy-saving safe solar term of a kind of serviceability temperature in 1000 ℃ of-1600 ℃ of scopes.
Background technology:
As shown in Figure 1, existing luminescent material and other materials are accomplished sintering under 1200 ℃ of-1600 ℃ of high temperature high temperature sintering furnace has two kinds on Muffle furnace and tunnel electric furnace, no matter be Muffle furnace and tunnel electric furnace; They all are made up of airtight casket A1, sealing steel plate casket A2, molybdenum filament heating element heater A6; Airtight casket A1, sealing steel plate casket A2 are the heating furnace body of two sealings, and molybdenum filament heating element heater A6 is fixed in the body of heater, during actual production; Open air valve A8, through tracheae A7 and A5 transport of H
2And N
2Mist in airtight casket A1, sealing steel plate casket A2, material to be sintered is placed crucible A4, crucible A4 places on the push pedal A3, sends into then and carries out sintering in the body of heater.Its weak point is:
1, because molybdenum filament in very easily oxidation of air heat; The boiler tube that for this reason will be wound with molybdenum filament is placed in the sealing steel plate casket; And the hydrogen+nitrogen that feeds content >=15% adds and gives protection; In the hope of normal service life, but have the potential safety hazard of murther: 1. 15% hydrogen has surpassed explosion limit, in case with air in oxygen blast after contacting; 2. the loss of additive decrementation hydrogen and nitrogen and electric energy when electric furnace moves.
2, direct interface heating temperature height and the heat that contacts with molybdenum filament of electric-furnace-tube is shaken greatly, causes boiler tube short service life.
3, the luminescent material that burns till exists pyroreaction incomplete defective in bottom to cause, and the luminescent material relative brightness has only 98-99%.
The utility model content:
The purpose of the utility model is exactly the deficiency to prior art, and a kind of high-temperature electric resistance furnace of energy-saving safe solar term is provided.The utility model is with silicon molybdenum both sides radiation heating, and the heat temperature equalization property of shaking is good, and the boiler tube life-span is long.The hydrogen consumption is few, and security is good.
The technological solution of the utility model is following:
The high-temperature electric resistance furnace of energy-saving safe solar term is characterized in that: comprise furnace roof, Si-Mo rod heating element heater, furnace wall, furnace bottom, push pedal, crucible, reach air inlet pipe; Furnace roof, furnace wall and furnace bottom constitute the body of heater of a sealing; The Si-Mo rod heating element heater is fixed in the body of heater and places the front portion of body of heater two sides respectively; Push pedal is positioned at body of heater and is arranged on the furnace bottom, and crucible then is located in the push pedal; Material to be sintered places the pincers pot.
As the improvement of technique scheme, the middle part of furnace roof is circular arc.
As the improvement of technique scheme, air inlet pipe one end sees through furnace roof and stretches in the body of heater; The end that air inlet pipe stretches in the body of heater is an air inlet, and the other end then is provided with air valve.
The beneficial effect of the utility model is:
1, with silicon molybdenum both sides radiation heating, the heat temperature equalization property of shaking is good, and the boiler tube life-span is long.
2, the hydrogen consumption is few, and security is good.
3, the controlled profit that is shaped on of hydrogen+nitrogen consumption is improved the quality of products.
4, the luminescent material relative brightness can reach 99.5-101%.

The specific embodiment:
Embodiment 1: see shown in Figure 2ly, the high-temperature electric resistance furnace of energy-saving safe solar term comprises furnace roof 1, Si-Mo rod heating element heater 2, furnace wall 3, furnace bottom 4, push pedal 5, crucible 6, and air inlet pipe 8; Furnace roof 1, furnace wall 3 and furnace bottom 4 constitute the body of heater of a sealing; Si-Mo rod heating element heater 2 is fixed on the left and right sides that places body of heater in the body of heater and respectively; Push pedal 5 is positioned at body of heater and is arranged on the furnace bottom 4, and 6 in crucible is located in the push pedal 5.
The middle part of furnace roof 1 is circular arc.
Operation principle: use Si-Mo rod can satisfy 1000 ℃-1600 ℃ serviceability temperature scope as thermal element, biggest advantage is: as protection, the hydrogen consumption is zero to heating power without hydrogen in air.The aluminium oxide of selecting high-quality for use is as in 1000 ℃ of-1600 ℃ of temperature ranges, processing the burner hearth in the atmosphere furnace by the steady operation material; No matter Muffle furnace and tunnel electric furnace; Meet the requirements of under the prerequisite in gas capacity and directly will burn till required requirement, inject hydrogen and nitrogen, usually at hydrogen about 5% by material high temperature; About nitrogen 95%; Controlled hydrogen manufacturing tolerance reaches purpose of safe operation in the explosion limit scope, controlled furnace atmosphere and stable furnace temperature are the assurances of raising and stabilized product quality.
