Abstract

The invention discloses a manufacturing method of a hollow ceramic membrane. The hollow ceramic membrane is processed through a hollow ceramic membrane mould. The hollow ceramic membrane is internallyprovided with one or more full-closed hollow holes. The mould comprises an upper shape mould, a lower shape mould and an inner mould core. The manufacturing method specifically comprises the following steps of first-time filling, mold core placing, second-time filling, semi-dry pressing forming, drying, glue discharging and sintering, and a finished hollow ceramic membrane is taken out after natural cooling. Through the manufacturing method, the defects that as for existing hollow ceramic manufacturing, a full-closed hollow ceramic membrane and a small-section hollow ceramic membrane cannot be manufactured, and the adjusting range of the membrane hole diameter is narrow are overcome; and compared with an existing method, the equipment requirement is low, equipment abrasion is little, thetechnique is simple, the efficiency is high, and manufactured hollow ceramic is integrally formed without the bonding step.

Description

technical field

[0001] The invention relates to a ceramic filter membrane technology, in particular to a manufacturing method of a hollow ceramic membrane. Background technique

[0002] Membrane separation technology is a new type of high-efficiency separation technology that uses the selective separation function of the membrane to achieve the separation, purification and concentration of different components of the feed liquid. With its high-efficiency separation characteristics, the membrane industry has been positioned as a strategic emerging industry by the country and has received strong policy support. Existing ceramic membranes mainly include hollow plate or tubular membranes, and the molding process generally adopts an extrusion molding process. The hollow ceramic membrane produced by this method has a symmetrical structure with openings at both ends. In the later stage, both ends need to be glued for sealing. Since the rubber seal is used, if the template is damag...
