Description
Technical field
The utility model belongs to heater, particularly a kind of be used for all kinds of large-scale canister equipment and
The novel frame formula resistive band heater of the postwelding stress relief annealing of large-scale hardware.
Background technology
At present, have two kinds by being used for all kinds of large-scale canister device on resistance band heater application modes: a kind of is to be used for assembly type resistance furnace mode of heating, is it is hung on the furnace wall of assembly type resistance furnace as heat source body; Another kind be used for spherical tank, the external stove integral annealing of ghost class tankages such as jar that crouch, frame type resistor band heater is placed in the container casing as heat source body, shell of tank coats with the light-weight refractory heat-insulating material and is incubated.The above-mentioned dual mode of (see figure 6) all is that the channel-section steel with carbon steel sheet compacting is two frames, does connector with four T shape porcelain spare connecting rods and nine tubulose porcelain spare connecting rods and two frames and T shape porcelain spare and tubulose porcelain spare are fused constituted the main body of frame heater.On four T shape porcelain spare connecting rods, respectively put on a string T shape porcelain spare.The high temperature resistance band is in the groove of the T shape porcelain spare formation of bunchiness.T shape porcelain spare has then played resistive band and mutual isolation and the insulating effect of framework, connecting rod and resistive band when the time comes.And nine tubulose porcelain spare connecting rods are divided into three groups, all wear full packages shape porcelain spare on the every connecting rod, in order to compress resistive band, the limiting resistance band is jumped out from the groove that bunchiness T shape porcelain spare forms under the condition of high temperature, with between resistive band in guarantee using and the framework and resistive band good insulation performance is arranged each other, in order to normal use.
Yet, but there is following defective in practice in this structural design: the one failure of insulation, main cause: (1) resistive band under the high temperature user mode owing to thermal expansion is extended loosening, be easy under the stress effect ditch that constitutes from bunchiness T shape porcelain spare and jump out poor and cause failure of insulation, thereby cause heater to be burnt out.(2) since two frames of former frame heater and all T shape porcelain spare and tubulose porcelain spares all link into an integrated entity by 13 connecting rods, and these 13 porcelain spare connecting rods are stud, have only after whole bolts are all tightened, it is as a whole that the frame heater can become.Stressed necessary uniformity when therefore requiring assembling.Be difficult to grasp but specifically implement.Twist when tight as the nut at connecting rod two ends, framework will become flexible, and in use its resistance to overturning is not strong, causes nut to come off, and framework is loosening, even whole heater falls apart.But tension or unbalance stress as nut is twisted will cause porcelain spare unbalance stress, and be very easily broken under the excess load pressure extrusion because of this genus of porcelain spare fragile material, thereby cause the frame heater insulation to destroy.This situation happens occasionally in actual production and use.Its two weight is big, the life-span short, security reliability is poor, main cause is: (1) is because T shape porcelain spare and tubular porcelain spare all are being through on the connecting rod after the assembling, and bear very big extruding force, so two kinds of porcelain spares, particularly the sectional dimension of T shape porcelain spare and weight are all bigger, thereby cause under the high temperature user mode, connecting rod produces flexural deformation under the gravity effect, and this situation is particularly outstanding in the performance of the connecting rod place of the upper/lower terminal of heater.(2) flexural deformation of connecting rod has further aggravated in use loosening of resistive band, thereby easier it is spun off from the groove that T shape porcelain spare is formed, form potential safety hazard, very easily cause short circuit, burn heater, thereby reduced the service life of heater.Above-mentioned technical problem is perplexing the people in the industry for a long time, needs to be resolved hurrily.
Summary of the invention
The purpose of this utility model is at the deficiency that exists in the above-mentioned technology, and a kind of novel frame formula resistive band heater is provided, and it is locked effectively and stops the displacement of resistive band and contact short circuit each other, and the situation of fundamentally having stopped failure of insulation takes place.
The purpose of this utility model realizes with following technical scheme: a kind of novel frame formula resistive band heater, it is characterized in that: it is by the rectangular frame of sealing, laterally equidistantly set up several connecting rods in the rectangular frame, and two connecting rods up and down wherein are resistant to bending special-shaped connecting rods, bunchiness connects the porcelain spare that resistive band is sealed in locking respectively on each connecting rod, described porcelain spare is that a middle part has the body that coincide and be connected with connecting rod, body up and down two ends correspondence is provided with the groove of locking sealing resistive band, and the size of groove be porcelain spare with porcelain spare to adorning the groove frame that the is connected in series resistive band of packing into just.
Described special-shaped connecting rod is the different in nature connecting rod of a general ovalize of section, Long Circle, I-shaped or rectangle, also can be the counter-bending special-shaped connecting rod that is formed by two circular connecting rod assembly weldings at least.
Described porcelain spare body and the formed shape of groove generally are E shape, day font or king's font.
The utility model has significant advantage and beneficial effect under the structure configuration of excellence.Learn to have following advantage at least by above technical scheme: improved the security performance in insulating properties, unfailing performance and the use of heater self.The more former heater of average operational failure rate of novel frame formula resistive band heater has reduced more than 80%; Reduce the weight of heater self significantly, 50% of the not enough former heater of the gross weight of novel frame formula resistive band heater; Strengthen heater integral rigidity, fastness and stability, thereby prolonged its service life.The service life of novel frame formula resistive band heater, more former heater improved 2 times, and was easier to maintenance.Can be rated as have novelty, the good technology of creativeness, practicality.
