Because the pressure inside the canister 1 is very large during high-pressure filtration, if the number of the filtrate outlets 132 is too small and the pore size is too large, the filter paper 131a may be perforated, and therefore, the base 13 is provided with a plurality of sieve pores, so that the pressure received by the filter paper 131a during high-pressure filtration is dispersed, the perforation of the filter paper 131a is avoided, solid-phase particles of the sanitary ceramic slurry cannot be separated from the liquid phase, and the filtration effect is reduced.
Specifically, the height of the sidewall 133 of the base 13 is greater than the sum of the heights of the filter paper 131a and the sealing rubber pad 131 b. The base 13 is a disc-shaped structure, so that the outer edge is provided with a side wall 133, and the side wall 133 can prevent the sanitary ceramic slurry from seeping out from the gap between the slurry storage cylinder 12 and the sealing rubber pad 131b by the high pressure in the filter tank 1 in the high-pressure filtering process.
Specifically, one end of the gas pipe 3 is provided with a pressure regulating valve 31, and the gas pipe 3 is connected with an external air pressure device through the pressure regulating valve 31. The pressure regulating valve 31 is constructed and operated in a manner similar to that of the conventional pressure regulating valve 31, and the pressure regulating valve 31 can display the pressure in the gas pipe 3 and thus reflect the pressure inside the canister 1. The detection personnel can adjust the air input pressure of the air delivery pipe 3 through the pressure regulating valve 31 according to the actual situation, and the pressure inside the filter tank 1 is changed.
Specifically, the bottom surface of the placing table 21 is further provided with a collecting funnel 212, and the collecting funnel 212 is located below the liquid discharge through hole 211.
