Description

Technical Field

[0001] The utility model relates to the technical field of ceramics, in particular to an internal heating sintering device for ceramic production. Background Art

[0002] Ceramics is a general term for pottery and porcelain. Pottery and porcelain have different textures and properties. Pottery is made of clay with high viscosity and strong plasticity as the main raw material. It is opaque, has fine pores and weak water absorption, and makes a turbid sound when struck. Porcelain is made of clay, feldspar and quartz. It is translucent, non-absorbent, corrosion-resistant, hard and tight, and makes a crisp sound when struck. It has high quality and beautiful shape, has high artistic value, and is famous throughout the world. Ceramics are pulled through embryonic drawing equipment. After the ceramic mud embryo is pulled, sintering equipment is needed to heat the ceramics at high temperature to sinter them into shape.

[0003] A Chinese document with publication number CN213955979U has been searched and disclosed an internal heating sintering device for ceramic production, which belongs to the field of ceramic technology and includes a heating box, a diverter box, a hot air blower, an air supply tube, a carrier plate, a partition plate, a limit frame, a cover plate, an insulation layer, an AC motor, a high-temperature heating tube, a baffle, a piston cylinder, a piston ring, a spring, a telescopic tube, a protective tube and an exhaust pipe. The diverter box is fixed to the top of the heating box by a support rod, a hot air blower is embedded in the left side of the heating box, an air supply tube is embedded above the diverter box, and four carrier plates are fixedly connected to the inner wall of the heating box. The telescopic tube in the utility model moves downward during heating, and the telescopic tube extends into the interior of the ceramic. The exhaust pipe at the bottom of the telescopic tube evenly transports the hot air flow to the interior of the ceramic, so that the hot air flow inside the ceramic flows quickly, and the interior of the ceramic is quickly heated and sintered. At the same time, the hot air flow flows quickly on the outside of the ceramic, so that the ceramic is quickly heated and sintered. It has the advantages of high sintering efficiency and uniform heating. The device uses wind power to drive the piston to move, and extends the telescopic tube into the interior of the ceramic for heating. However, the stability of the wind power output is poor, and the telescopic length cannot be controlled according to demand, which easily affects the sintering results when heating ceramics with different needs. At the same time, the device does not have a convenient disassembly function of the heating tube, so that a lot of time needs to be spent on disassembling the heating tube during maintenance and replacement. In view of the above problems, an internal heating sintering equipment for ceramic production is provided herein. Summary of the invention
