Vertical resistance furnace: can take hanging burning method to fire pipe (ball, post, ring) shape ceramics sample, but the necessary prefabricated hanger of sample, sintering cuts off it afterwards again, makes process complications.And sample amount of firing and sample length are fired by burner hearth and flat-temperature zone size restriction, and efficient is low.Sample also need be fired in batches, and every batch of sample all must heating and cooling process of experience.It is long that a large amount of samples are fired required time, the energy consumption height.Because slow with the stove cooling rate, ceramic crystalline grain is grown up easily, influences ceramic performance.And sample is unbalance stress in hanging the burning process, easily cracks, and influences ceramic performance.
Summary of the invention
First purpose of the present invention is to overcome above-mentioned deficiency, provide a kind of in pipe (ball, post, ring) shape ceramics sample sintering procedure indeformable rotation firing furnace.
Second purpose of the present invention is to overcome above-mentioned deficiency, provide a kind of continuously, in batches, energy-conservation, save time and fire the rotation firing furnace of pipe (ball, post, ring) shape ceramics sample.
The 3rd purpose of the present invention is to overcome above-mentioned deficiency, provide a kind of can be with the stove firing furnace of rotation easily of shove charge at any time as required that heats up again.
The 4th purpose of the present invention is to overcome above-mentioned deficiency, and a kind of rotation firing furnace of time saving and energy saving automatic turnover sample is provided.
First purpose of the present invention is achieved in that a kind of rotation firing furnace, comprises body of heater 1, tumbler 2, burner hearth axle sleeve 3, automatic temperature control instrument 4 and current transformer 5 compositions.Tumbler is connected with body of heater, and body of heater is rotated in sintering process; Automatic temperature control instrument one end is connected with body of heater and measures furnace body temperature, and the other end is connected with current transformer regulates electric current and transformation; Current transformer is connected with body of heater, and control also changes furnace body temperature.
Body of heater 1 is made up of fireproof insulation brick 11, silicon molybdenum (silicon-carbon) rod 12, cylindrical burner hearth 13, fire door brick 131, thermocouple 14, fot screw 15.Silicon molybdenum (silicon-carbon) rod, thermocouple are connected with automatic temperature control instrument, current transformer by electric wire respectively.The burner hearth inclination angle is regulated by fot screw.
Tumbler 2 is made up of motor 23, gear 21 and 31, driving chain 22, and motor driven gear 21 also drives driving chain and links to each other with gear 31.Gear 31 is connected with cylindrical burner hearth 13.
Burner hearth axle sleeve 3 is made up of water collar 32, water inlet 321, delivery port 322.Burner hearth axle sleeve 3 is fixed on the burner hearth 13 two ends outer walls, is fixed on the gear 31 on burner hearth axle sleeve 3 outer walls.
Drive the tubulose burner hearth by the variable-ratio tumbler and rotate, the sample in the burner hearth is rotated thereupon, can guarantee not deform in the sample sintering process, keep good roundness and integrality.
Second purpose of the present invention is achieved in that a kind of rotation firing furnace, and its burner hearth is little to incline, and in rotation was burnt till continuously, sample at the uniform velocity moved to the burner hearth other end automatically, and translational speed is by rotating speed and inclination angle decision.As long as sample packs into continuously, just can realize continuously, in batches, energy-conservation, timesaving fires purpose.
The 3rd purpose of the present invention is achieved in that a kind of rotation burns till firing furnace, burner hearth is radial symmetric structure, and two ends are stopped up with the fire door brick, opens at any time when advancing (going out) material, sample can be with stove intensification shove charge at any time as required again, very succinct, convenience like this.
The 4th purpose of the present invention is achieved in that a kind of rotation firing furnace, and burner hearth is radial symmetric structure, and warm area is radial symmetric also, and two ends are stopped up with the fire door brick, opens at any time when advancing (going out) material; Burner hearth is little to incline, and in rotation was burnt till continuously, sample successively at the uniform velocity moved to the body of heater other end automatically through heating zone-flat-temperature zone-cooling area.Translational speed is set corresponding rotating speeds and inclination angle according to the technological parameter requirement.Rotating speed is regulated by tumbler, and the inclination angle is regulated by fot screw.Thus can be automatically, come out of the stove continuously, save the time of the required wait of heating and cooling repeatedly, shortened the firing time of pottery in enormous quantities greatly.
