[Problems to be Solved by the Invention]
The present invention has been made to solve these problems, and the through holes that should not be sealed are sealed without forming protrusions or drips made of the sealing paste on the end face of the ceramic molded product. without causing problems such suitably sealing method of a ceramic molded body can perform sealing treatment, sealing apparatus used for sealing processing of the ceramic molded body, a porous a ceramic molded body sealed with the sealing method It is an object of the present invention to provide a method for manufacturing a quality ceramic member and a method for manufacturing a ceramic filter using the porous ceramic member obtained by the above manufacturing method.

Further, in the third invention, the end portion of the through hole of the columnar ceramic molded body in which a large number of through holes are arranged side by side in the longitudinal direction across the partition wall is made of a sealing paste containing ceramic powder as a main component. A sealing device for sealing, which is a sealing paste discharge tank in which a mask having holes formed in a sealing pattern is installed on the side surface and is configured to be movable in an arbitrary direction, and the above-mentioned discharge tank. The stirring piece disposed inside and the mask inside the discharge tank are arranged at a position slightly distant from each opening so as to face each opening and can move in the opening direction. It is a sealing device for a ceramic molded product, which is provided with a plurality of pins.
The fourth aspect of the present invention is a method for producing a porous ceramic member, which comprises firing a ceramic molded article sealed by the method for sealing the ceramic molded article of the first or second invention.
A fifth aspect of the present invention is a method for producing a ceramic filter, which comprises bundling a plurality of porous ceramic members produced by the method for producing a porous ceramic member of the fourth invention.

Claims (7)

  A ceramic molded body sealing method in which a plurality of through-holes are arranged in parallel in the longitudinal direction across a partition wall, and the end portions of the through holes are sealed with a sealing paste mainly composed of ceramic powder. Then, after contacting the mask formed with an opening in the shape of a sealing pattern on the end surface of the ceramic molded body, the paste for sealing enters the through hole of the ceramic molded body from the opening of the mask, Next, after the operation of reducing the cross-sectional area of the end surface of the through hole of the sealing paste is performed, the mask is pulled away from the end surface of the ceramic molded body.   A ceramic molded body sealing method in which a plurality of through-holes are arranged in parallel in the longitudinal direction across a partition wall, and the end portions of the through holes are sealed with a sealing paste mainly composed of ceramic powder. Then, after contacting the mask formed with an opening in the shape of a sealing pattern on the end surface of the ceramic molded body, the paste for sealing enters the through hole of the ceramic molded body from the opening of the mask, Next, after the operation of reducing the volume of the sealing paste in the vicinity of the end face of the through hole is performed, the mask is separated from the end face of the ceramic formed body.   The method for sealing a ceramic molded body according to claim 1, wherein after the sealing paste is made to enter the through hole of the ceramic molded body from the opening of the mask, an operation of shifting the mask along the end surface of the ceramic molded body is performed.   3. The method for sealing a ceramic molded body according to claim 1 or 2, wherein after the sealing paste is made to enter the through-hole of the ceramic molded body from the opening of the mask, the pin is inserted into each opening of the mask.   A sealing device for sealing the end of the through-hole of a columnar ceramic molded body in which a large number of through-holes are arranged in parallel in the longitudinal direction across a partition wall with a sealing paste mainly composed of ceramic powder. A sealing paste discharging tank configured so that a mask in which openings are formed in a sealing pattern is installed on the side surface and movable in an arbitrary direction; and a stirring piece disposed inside the discharging tank; And a plurality of pins arranged to be opposed to the respective openings at positions slightly apart from the mask inside the discharge tank and configured to be movable in the opening direction. A sealing device for a ceramic molded body. A method for producing a porous ceramic member, wherein the ceramic molded body sealed by the sealing method according to claim 1 is fired. A method for producing a ceramic filter, comprising binding a plurality of porous ceramic members produced by the production method according to claim 6.
