泡剤と汚水を接触させる方法であつた。 These defoaming devices include systems that use defoaming pumps, systems that use liquid defoaming agents, and systems that use solid defoaming agents. A method has been proposed in which a filled cartridge is immersed in waste water to dissolve and add an antifoaming agent. (Utility Model Publication No. 63-41052 and Utility Model Application No. 1988
-1407 Publication) Problems to be Solved by the Invention Conventionally known defoaming devices using solid defoaming agents have slits or holes bored in the lower side wall and bottom of a cylindrical container, as shown in Fig. 4. In this method, the solid antifoaming agent and the waste water were brought into contact by filling a dissolved dissolver with the chemical and immersing the bottom of the dissolver in waste water.
しかしながら、前記の消泡装置は常に固形消泡
剤が汚水に接触しているため、固形消泡剤が過度
に溶解して長期の使用が出来ないものであつた。 However, in the defoaming device described above, the solid defoaming agent is constantly in contact with the waste water, so that the solid defoaming agent dissolves excessively and cannot be used for a long period of time.
またスリツトあるいは孔を形成した溶解器を汚
水の上方に吊り下げて用いる場合には、溶解器の
透孔部分に厚みがあるため、泡がスリツトあるい
は孔から溶解器の内部に通過し難いので、十分な
消泡効果が得られなかつた。 Furthermore, when a dissolver with slits or holes is suspended above waste water, the through-hole portion of the dissolver is thick, making it difficult for bubbles to pass through the slits or holes into the dissolver. A sufficient defoaming effect could not be obtained.
固形消泡剤を網状の袋体に充填して、汚水の上
方に吊り下げる方法も考えられているが、薬剤を
充填した袋体が不安形となり、汚水面からの高さ
及び薬剤と汚水の接触量が絶えず変化するので、
汚水に対する消泡剤の供給量に著しい過不足を生
じる欠点があつた。 A method of filling a mesh bag with a solid antifoam agent and suspending it above the wastewater has been considered, but the bag filled with the drug becomes unstable, and the height from the wastewater surface and the drug and wastewater are Since the amount of contact changes constantly,
There was a drawback that the amount of antifoaming agent supplied to the wastewater was significantly excessive or insufficient.

る。Means for Solving the Problems The inventors of the present invention have conducted repeated studies to solve these problems, and found that they filled a dissolver with a solid antifoaming agent, and placed the lower part of the melter on the surface of the rising foam. In a hanging antifoaming device that is suspended above the water surface as if in contact with the water, the drug storage part in the dissolver is cylindrical, made of wire material with a wire diameter of 2 mm or less, and has a large mesh. By providing a net-like basket with a height of 5 mm or more and protruding 3 to 8 cm below the lower end of the cylindrical storage part, the solid antifoaming agent is dissolved in proportion to the amount of foam generated, and the antifoaming effect is improved. We have discovered a defoaming device that can sustainably exhibit the following effects.

解量が著しく低下する。 The net-like basket provided below the cylindrical storage part is made of synthetic resin or corrosion-resistant metal material, the wire diameter of the wire material is 2 mm or less, preferably 1 mm or less, and the mesh size is 5 mm or more. . If the thickness of the wire material of the mesh basket exceeds 2 mm, the amount of solid antifoaming agent dissolved will decrease significantly.
本考案の溶解器に用いられる網状かごの形状と
しては、半球状、椀状あるいは円筒状のいずれで
もよいが、格納部の下端から下方に３〜８cm程度
突出させている。 The shape of the mesh basket used in the melter of the present invention may be hemispherical, bowl-shaped, or cylindrical, and it projects approximately 3 to 8 cm downward from the lower end of the housing.

止めすれば良い。 In implementing this proposal, in order to fix the cylindrical storage part and the mesh basket, a band-shaped protruding edge is formed at the lower end of the storage part, this is fitted into the opening of the mesh basket, and it is tied with a string. Alternatively, they may be screwed together using an annular fastener.

速やかに溶解する。Effect According to this invention, a net-like basket with a mesh size of 5 mm or more made of wire material with a wire diameter of 2 mm or less is placed in the cylindrical storage part 3 to 8 cm below the lower end of the cylindrical storage part.
Since the solid defoamer is provided so as to protrude, the solid defoamer comes into contact with its own weight and foam and softens, so that the wires of the net-like basket dig into the defoamer and the surface of the solid defoamer becomes net-like. Since the net-like basket protrudes from the basket (see Figure 3) and is located at the lowest position of the dissolver, the solid defoamer and foam come into direct contact and the defoamer is quickly dissolved.

It is suspended and the generated bubbles 12, 12... are brought into contact with the lower part of the melter. The solid antifoaming agent 10 is softened by coming into contact with the foam 12, and the solid antifoaming agent 10 becomes wedged into the filamentous material 6 of the mesh basket 5 as shown in FIG. In this case, the solid antifoaming agent 10 and the foam 12 come into direct contact with each other, so that the antifoaming agent 10 is quickly dissolved and an efficient antifoaming effect can be obtained.
