Abstract

Disclosed is a plasma sterilizer apparatus for a pipe and, more particularly, to a plasma sterilizer apparatus for a pipe, which can be easily mounted on a pipe and effectively sterilize harmful microorganisms contained in water or raw materials flowing through a pipe. A plasma sterilizer apparatus for a pipe comprises: a first connection member connected to one side of a pipe; a second connection member connected to the other side of the pipe; a first electrode mounting member disposed in contact with the first connection member; a second electrode mounting member disposed in contact with the second connecting member; a first electrode member provided on the first electrode mounting member; and a second electrode member provided on the second electrode mounting member.

First claim

What is claimed is:

1. A plasma sterilizer apparatus, comprising;
a first connection member connected to a first pipe;
a second connection member connected to a second pipe;
a first electrode mounting member disposed in contact with the first connection member;
a second electrode mounting member disposed in contact with the second connection member;
a first electrode member seated on the first electrode mounting member; and
a second electrode member seated on the second electrode mounting member,
wherein the first electrode member comprises a first plane electrode of mesh structure which is woven with first conductive linear members, and a first electrode wire which extends from the first plane electrode to an external power line,
wherein the second electrode member comprises a second plane electrode of mesh structure which is woven with second conductive linear members, and a second electrode wire which extends from the second plane electrode to the external power line,
wherein the first electrode mounting member comprises a first install body which is detachable from the first connection member and has a center-hollowed circular and planar shape; a first seating groove to seat the first electrode member on one surface of the first install body; a first electrode lead-in part which protrudes from an outer surface of the first install body in a radial direction and has a first lead-out hole formed in the radial direction where the first electrode wire leads out through; and a first sealing cover which covers a distal end of the first electrode lead-in-part,
wherein the second electrode mounting member comprises a second install body which is detachable from the second connection member and has a center-hollowed circular and planar shape; a second seating groove to seat the second electrode member on the second install body; a second electrode lead-in part which protrudes from an outer surface of the second install body in a radial direction and has a second lead-out hole formed in the radial direction where the second electrode wire leads out through; and a second sealing cover which covers a distal end of the second electrode lead-in part,
wherein the plasma sterilizer apparatus further comprises one or more interval adjusting members disposed between the first and second electrode members to adjust a distance between the first and second electrode members,
wherein the first connection member has a first sealing member inserting hole grooved and formed thereon, and a first sealing member is disposed in the first sealing member inserting hole to be adjacent to the first electrode mounting member,
wherein the second connection member has a second sealing member inserting hole grooved and formed thereon, and a second sealing member is disposed in the second sealing member inserting hole to be adjacent to the second electrode mounting member, and
wherein the plasma sterilizer apparatus further comprises a locking member to connect the first connection member and the second connection member.

2. The plasma sterilizer apparatus according to claim 1 ,
wherein the first and second electrode mounting members, on which the first and second electrode members are respectively seated, make a plurality of pairs.

3. The plasma sterilizer apparatus according to claim 2 ,
wherein the one or more interval adjusting members are interposed between the plurality of pairs of the first and second electrode mounting members.

4. The plasma sterilizer apparatus according to claim 1 ,
wherein each of the first and second connection members comprises a flange on which multiple locking holes are formed in a circumferential direction thereof, and
wherein the locking member comprises a plurality of bolts inserted in the locking holes and a plurality of nuts fastened with the plurality of bolts.
