But; Generally refractory material constitutes saggar by the good aluminum oxide of resistance to sudden heating, mullite, cordierite, carbonization be siliceous etc.; Owing to have the big such characteristic of thermal capacity; In the refrigerating work procedure of continuous firing process, be difficult to carry out the cooling of saggar especially, have the such problem of cooling effectiveness difference of inner powder of accommodating.
The utility model content
The problem that the utility model will solve
The purpose of the utility model is to address the above problem, and what be provided at the powder that used saggar burns till when handling the roller kilns that the cooling effectiveness of the powder that accommodate saggar inside in refrigerating work procedure is good continuously.
Be used to solve the structure of problem
Be used to solve the roller kilns of the 1st aspect of the utility model of above-mentioned problem; Inside at body of heater with heat up zone, maximum temperature retaining zone and cooled region; Dispose a plurality of conveyances at certain intervals and use roller; It is characterized in that the conveyance of this cooled region possesses from the roller inside of hollow structure to by the refrigerating gas squit hole of transport object ejection refrigerating gas with to the refrigerating gas supply structure of roller internal feed refrigerating gas with roller.
The 2nd aspect of the utility model is characterised in that; In the roller kilns aspect the 1st; The conveyance of perforation body of heater configuration is supported by the roller drive division with an end of roller; The other end is supported by the roller portion of bearing, and the refrigerating gas supply structure is supplied with refrigerating gas via the refrigerating gas introducing port of the conveyance of supplying with the refrigerating gas supply port of refrigerating gas in the seal box that bears portion to this roller of covering and in seal box, supporting in the roller portion of bearing with the end setting of roller.
The 3rd aspect of the utility model is characterised in that, aspect the 1st or in the roller kilns of the 2nd aspect, is the saggar that contains powder by transport object.
The utility model effect
Inside at the body of heater with heat up zone, maximum temperature retaining zone and cooled region disposes in the roller kilns of a plurality of conveyances with roller at certain intervals; The conveyance of this cooled region is with possessing on the roller from the roller inside of hollow structure to by the refrigerating gas squit hole of transport object ejection refrigerating gas with to the refrigerating gas supply structure of roller internal feed refrigerating gas; Through adopting such formation; Under the situation of the powder of being accommodated for saggar inside by transport object; Owing to can cool off to the big saggar of the thermal capacity refrigerating gas of directly jetting; The cooling of the saggar that in cooled region cooling is difficult to carry out can be promoted in the past, the cooling effectiveness of the powder of accommodating this saggar inside can also be improved.

Symbol description
Roller is used in the conveyance of 1 cooled region, 2 refrigerating gas squit holes, and 3 refrigerating gas supply ports, 4 bodies of heater, 5 roller drive divisions, 6 rollers bear portion, 7 seal boxs, 8 by transport object, 9 refrigerating gas introducing ports.
The specific embodiment
The preferred implementation that below shows the utility model.
The utility model is to dispose at certain intervals in the roller kilns of a plurality of conveyances with roller in the inside of the body of heater with heat up zone, maximum temperature retaining zone and cooled region, and the conveyance of cooled region is provided with roller inside from hollow structure to the refrigerating gas squit hole 2 that is sprayed refrigerating gases by transport object 8 with roller 1.In addition, possesses refrigerating gas supply structure to roller internal feed refrigerating gas.(for example re-crystallized silicon carbide etc.) gets final product not special the qualification so long as the material of excellent heat resistance with the material of roller in conveyance.
In this embodiment are the saggars that contain powder by transport object 8; Be warming up to the firing temperature of powder from room temperature in the zone of heating up; Under the firing temperature of maximum temperature retaining zone, burn till processing, be cooled to room temperature from firing temperature at cooled region at powder.Need to prove; At zone and maximum temperature retaining zone and the resistance heated heater that likewise in stove, was provided with as electric heater of heating up in the past; Their energisings are made the heating of resistance heated heater, mainly heat the powder of in saggar, accommodating through radiation heating.
As shown in Figure 1, the conveyance of cooled region connects body of heater 4 with roller 1 and disposes, and conveyance is born portion 6 by roller and supported by the support of roller drive division, the other end with an end of roller 1.
The conveyance of cooled region with the end of roller 1 by 7 coverings of seal box of purge of gas (パ one ジ) formula; Seal to avoid upsetting the atmosphere in the stove with roller 1 with the intrusion of the extraneous gas in the gap of through hole portion from conveyance; Wherein sealing case 7 is configured to cover the through hole portion that connects body of heater 4.
