Secondly, connect end cup-shaped structure crucible, can only take the injection forming mode to make basically; And injection forming; Moisture content is higher, and need treat after the moulding that the sclerosis of gypsum suction base substrate has after certain intensity could the demoulding, and the production cycle is long; Usually need the demoulding of 1-2 hour ability based on ambient air temperature and humidity, production efficiency is low; Adopt compression moulding, need the cylindrical shell and the end to separate and suppress, assemble sintering then, not only the many same production efficiencys of manufacturing process are not high, and the easy generation of secondary compacting density is inconsistent, increases cracking probability when causing burning till, and sintering qualified rate is affected.
Above-mentioned deficiency still has is worth improved place.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned prior art, and a kind of not cracky is provided, long service life, and make simple ceramic crucible.
The object of the invention realizes that main the improvement is ceramic crucible to be made the no end be used to logical tubular and two combining structures of assembling plate, during the charging sintering; The base plate that is connected makes it to become has bottom structure, behind the sintering base plate is separated with cylindrical shell, and cylindrical shell of the no end not only makes things convenient for the discharging of sintered material; And easy to clean; Basically can not damage ceramic crucible, thereby overcome the deficiency of prior art, realize the object of the invention.Specifically, ceramic crucible of the present invention comprises that containing the hollow of burning material holds body, it is characterized in that crucible holds body and uses assembly to form by sintering cylindrical shell of the no end and sintering base plate.
Among the present invention.
Constitute the cylindrical shell of the no end of crucible, its cross sectional shape is not limit in theory, can be various geometrical cross-sectional shape, but prepare angle from pottery, and more employing cylindrical structure is fired the qualification rate height.Drum shaft to, can be the straight tube of equal-sized equal diameter up and down, also can be to be up big and down small cup-shaped with prior art; Be up-small and down-big shape cylindrical shell better wherein; This structure more helps being shifting out of solid columnar material behind the sintering, only needs to separate mounting bedplate, mentions the crucible cylindrical shell and gets final product.
Sintering cylindrical shell of the no end and sintering base plate use assembly, equal sinter moldings, and assembling connects when placing sintered material and firing; Can move with prior art is convenient and (for example feed and move; Loading of kiln, kiln discharge), and behind sintering, can separate easy-unloading and cleaning.And sintered material basically all is solid powder/particle or particulate material, so only need be the sintering base plate temporary transient relative fixed that can link to each other with the sintering cylindrical shell, can be used in carrying and moves and can satisfy instructions for use.The two assembling assembles; Can adopt multiple connected mode commonly used in the prior art, snap in inside and outside for example and plug together formula, connecting portion can threaded engagement connect; Also can adopt the eye-splice swivel hook hanging; Can also adopt similar lid shape base plate, radially with pin joints such as pottery pin, ceramic screw, connected mode is common prior art.
Ceramic crucible of the present invention is with respect to prior art, owing to changed the ceramic crucible structure; Adopt bottomless drum shaped and two combining structures of sintering base plate of sintering, be assembled into the band bottom structure when charging, sintering, behind the sintering cylindrical shell and the end are separated; Do not change original use, greatly facilitate discharging behind the sintering, and the cleaning after adhering to; Scale removal process can not cause crucible to damage basically, has greatly improved turnover service life.Particularly up-small and down-big shape cylindrical shell only needs forward to mention tube of the no end during discharging, with regard to the ability easy-unloading, very convenient for being the discharging of cylinder material behind the sintering especially, the cylinder material is easy to.Because crucible by bottomless drum shaped and two combinations of base plate, makes that the crucible structure is simpler, thereby can adopt hot pressing slip casting (injection) moulding; Get final product the demoulding after the moulding like this, compole is short suddenly, and average clock more than 1 minute just can be made one; Improve production efficiency greatly, reduced production cost.Though need when using the end and cylindrical shell combination, both combinations only are simple fixation, it is many easily to add the end with respect to manufacturing, and therefore can think does not increase the use workload basically, adds that material is simple clearly behind the sintering, has also improved service efficiency.The present invention's thinking of breaking the normal procedure is made the disome combining structure with ceramic crucible, has greatly made things convenient for discharging and cleaning, has reduced the breakage when using, and is the significant improvement to ceramic crucible.
