Accompanying drawing explanation
Fig. 1 is the structural representation of the slip casting device of an embodiment;
Fig. 2 is the top view at the top of the nutsch filter of slip casting device as shown in Figure 1;
Fig. 3 is the schematic diagram of the knockout course of slip casting device as shown in Figure 1.
Detailed description of the invention
Mainly in combination with drawings and the specific embodiments, slip casting device is described in further detail below.
In conjunction with Fig. 1～Fig. 3, the slip casting device of an embodiment, including: slip casting room 10, nutsch filter 20, filter membrane 30, fixture 40, vacuum chamber 50 and demoulding stem stem 60.
Slip casting room 10 is tubular. Concrete, slip casting room 10 can be rounded cylindrical, oval tubular, rectangle tubular or trapezoidal tubular.
Nutsch filter 20 is inverted tubbiness. Concrete, nutsch filter 20 can be round tank shape, oval tubbiness, oblong barrel shape or trapezoidal tubbiness.
The bottom of slip casting room 10 and the top of nutsch filter 20 are docked with plane, and filter membrane 30 is placed between slip casting room 10 and nutsch filter 20.
The top of nutsch filter 20 is provided with multiple filtration through hole 22. In conjunction with Fig. 2, filter through hole 22 and be arranged on the top of nutsch filter 20 according to matrix structure.
Concrete, the sidewall of nutsch filter 20 is provided with exhaust tube 24, and exhaust tube 24 is for being connected with vacuum extractor.
Exhaust tube 24 is provided with gas valve 26.
The inside of nutsch filter 20 is additionally provided with and filters the suction filtering tube 28 that through hole 22 connects, and the top of one end of suction filtering tube 28 and nutsch filter 20 is connected away from the side of slip casting room 10.
The bottom of slip casting room 10 is provided with the first extension 12 radially extended, and the top of nutsch filter 20 is provided with the second extension 29 radially extended, and the first extension 12 and the second extension 29 are clamped by fixture 40.
The opening gluing, sealing of the bottom of nutsch filter 20 and vacuum chamber 50, demoulding stem stem 60 and slip casting room 10 match, and demoulding stem stem 60 is for the demoulding after injection forming.
Concrete, the outside of the inner side of the bottom of nutsch filter 20 and the opening of vacuum chamber 50 is matte surface.
Below in conjunction with Fig. 1, slip casting process is briefly described.
Add slurry in slip casting room 10, close gas valve 26 so that vacuum chamber 50 and ambient atmosphere isolation, open the vacuum extractor being connected with exhaust tube 24, start sucking filtration, after slurry is drained, gas valve 26 is opened so that ambient atmosphere enters into vacuum chamber 50, release vacuum state. Fixture 40 is unclamped so that slip casting room 10 and nutsch filter 20 separate, and complete slip casting.
Below in conjunction with Fig. 3, the knockout course of this slip casting device is simply introduced.
Before the demoulding, base substrate 200 is arranged in slip casting room 10. During the demoulding, demoulding stem stem 60 is used to extrude base substrate 200 from top to bottom. After the demoulding, demoulding stem stem 60 is arranged in slip casting room 10, and idiosome 200 is deviate from slip casting room 10, completes the demoulding.
The slip casting room 10 of this slip casting device is upper and lower permeable structures, after slip casting, is separated in slip casting room 10 and nutsch filter 20, demoulding stem stem 60 is used to extrude base substrate 200 from top to bottom, complete the demoulding, it is prevented that the sidewall bonding of base substrate 200 and slip casting room 10 closely, causes and is difficult to the demoulding.Compared to tradition sucking filtration mould, this slip casting device is easy to the demoulding.
