Referring to fig. 1, a method for drying a ceramic blank according to an embodiment of the present application includes the following steps;
101. selecting a drying tool 1;
specifically, a drying tool 1 is selected according to the size, the shape and the thickness of a ceramic blank 2, and the drying tool 1 comprises two porous pressing plates 3; the porosity, the pore size and the thickness of the porous pressing plate 3 are selected according to parameters such as the size, the shape and the thickness of the ceramic blank 2, the porosity of the porous pressing plate 3 is 30-65% in the embodiment, and the pore size of the upper hole 31 is 1-100 um; for example: the porous pressing plate 3 with large porosity has small smoothness on the surface, is suitable for the ceramic blank 2 with large size and thickness and no particularly high requirement on the precision of the outer surface, and when the size and the thickness of the ceramic blank 2 are large, the porous pressing plate 3 with large porosity and large pore diameter can be selected, so that the appearance of the ceramic blank 2 is not influenced, and the dehydration and drying efficiency can be effectively improved; correspondingly, the ceramic blank 2 with smaller thickness and higher requirement on the precision of the outer surface needs to select the porous pressing plate 3 with smaller porosity and smaller pore diameter, so that the ceramic blank 2 can not be deformed due to overlarge porosity or overlarge pore diameter in the drying process, and the smoothness of the surface of the ceramic blank 2 can be effectively ensured.
The porous pressing plate 3 may be a porous plate made of ceramic or metal, in this embodiment, the thickness of the porous pressing plate 3 is 2mm to 40mm, and accordingly, in order to ensure stable compression of the ceramic blank 2 and avoid deformation or warpage in the drying process, the thickness of the porous pressing plate 3 may be selected according to the size of the ceramic blank 2, for example; the ceramic blank 2 with larger size and thickness needs a heavier porous pressing plate 3 for compressing, and the porous pressing plate 3 with larger thickness is selected.
Wherein, the ceramic body 2 is a biscuit with water content higher than 5% after demoulding by gel injection moulding, such as: 16%, the water content is regarded as a high water content, and the problems of deformation and warpage of the ceramic body 2 and long drying period cannot be guaranteed by using the conventional drying method, and the drying method provided in this embodiment can be used for ceramic bodies 2 with other water contents, of course.
102. Assembling a ceramic blank 2 to the drying tool 1 to form a drying unit 4, so that the ceramic blank 2 is pressed in the drying unit 4;
specifically, in order to ensure that the ceramic blank 2 can be compressed, one porous pressing plate 3, the ceramic blank 2, and the other porous pressing plate 3 are sequentially stacked, so that the two porous pressing plates 3 can clamp the ceramic blank 2, thereby forming the stacked drying unit 4.

In this embodiment, the liquid level of the drying solution 6 in the drying container 5 needs to be maintained at least 5mm above the top surface of the at least one drying unit 4, so as to ensure that all drying units 4 are completely covered and submerged, and insufficient drying is avoided.
Wherein, the drying container 5 has a receiving space for receiving at least one drying unit 4, and the drying container 5 has an opening for putting in/taking out the drying unit 4 and filling the drying solution 6, and a cover 7 is further required to seal the opening of the drying container 5 to prevent the drying solution 6 from volatilizing or evaporating to affect the effect of dehydration drying; the drying container 5 may be a container made of various materials such as plastic, glass, ceramic, and metal, as long as it is not corroded by the drying solution 6.
104. Sealing the drying container 5, standing and dehydrating for a first designated time;
specifically, the opening of the drying container 5 is closed by the lid 7 to seal the drying container 5, so as to prevent the drying solution 6 from volatilizing or evaporating; standing for the first designated time after sealing, so that water in the ceramic blank 2 can be naturally diffused into the drying solution 6 under the action of osmotic pressure until the water content between the ceramic blank 2 and the drying solution 6 is balanced, and the aim of drying and dehydrating is fulfilled; in the process, dehydration can be realized only by keeping standing without creating any temperature and pressure conditions.

105. And after the dehydration is finished, taking out the drying unit 4, and separating the ceramic blank 2 and the drying tool 4.
Specifically, after the dehydration is completed, that is, after the first designated time is reached, the cover body 7 of the drying container 5 is removed, the drying unit 4 is taken out from the opening of the drying container 5, the ceramic blank 2 and the drying tool 1 are separated, and the ceramic blank 2 is reserved or directly enters a glue discharging process.
According to the above list, in the ceramic blank drying method provided by the first aspect of the present application, the ceramic blank 2 is assembled by the drying tool 1 to form the drying unit 4, so that the ceramic blank 2 is compressed in the drying unit 4, the ceramic blank 2 can be ensured to be compressed in the dehydration process, and the occurrence of warping deformation is avoided; the drying of the ceramic blank 2 can be completed by sealing and standing the at least one drying unit 4 by using the drying container 5 and the drying solution 6 for dehydration, and because the water content of the drying solution 6 is less than that of the ceramic blank 2, the ceramic blank 2 can be dehydrated and dried by a simple osmotic pressure principle, the operation steps are greatly simplified, the ceramic blank can be effectively dehydrated without manufacturing any harsh reaction environment, and the problems of large warping deformation of a dried sample, serious influence on the surface shape precision of a product, complex operation and long drying period of the existing ceramic blank 2 drying method are effectively solved.
