Abstract:
A protein foam remover for aquarium, comprising a water pump, a protein foam removing means, and a water flow buffer, wherein:said water pump comprising a pump body with an incoming chamber, an incoming pipe extended downward from an opening at the bottom of said incoming chamber, an outgoing pipe extended sideway from one side of said incoming chamber, a vane for drawing and whirling the water flow into said incoming chamber, an air inlet connector disposed at an appropriate position on the sidewall of said incoming pipe and perpendicularly coupled with said incoming pipe and pressing against the corresponding inner side of said incoming pipe, an air supply pipe connected to the outer side of the air inlet connector protruding above the water surface of an aquarium, and an aslant cut opening disposed on the upper surface of said air inlet connector in said incoming pipe and facing said vane; said protein foam removing means comprising a hollow cylindrical foam removing body disposed on a lower base, a backflow pipe connected to the bottom of said foam removing body and disposed on one side of the lower base, a cylindrical whirling tank having a bottom substantially in a conical shape and disposed on the inner side of the bottom of said foam removing body, a foam outlet connector in a flare tapered shape disposed at the top end of said foam removing body, and the top end of said foam outlet connector being coupled with the bottom of a central vertical foam inlet pipe disposed on a protein foam collecting cylinder, an incoming pipe passing through and disposed on an appropriate position on the sidewall of said foam removing body, and the outer side of said incoming pipe being coupled to said outgoing pipe disposed on said water pump, and the inner side of said incoming pipe being appropriately extended downward into the water flow whirling tank; said incoming pipe at the end of its inner side having a jet connector each appropriately being extended toward two corresponding sides, and both ends of said jet connector respectively having a jet opening for spraying the water at an appropriate angle; said water flow buffer, comprising a box body hung on a position with an appropriate height of the inner sidewall of said aquarium, and the box body being divided into an incoming chamber and an air bubble removing chamber by an inner wall lower than the central partitioning wall in said box body, and the lower section of said air bubble removing chamber having a plurality of groove openings passing through the sidewalls and bottom of said box body, and the water flow buffer having an air bubble isolating layer in said air bubble removing chamber for isolating the air bubbles in the water; in said incoming chamber, one end of said incoming chamber being coupled to a diversifying pipe disposed at a backflow pipe of said protein foam remover, therefore with the assembling of the foregoing component and when the water pump being turned on, the water pump with an air mixing function producing a water flow with numerous tiny air bubbles from the filthy water containing protein impurities and flowing such water into said protein foam remover; by the corresponding structure of the jet openings of said jet connector and the inner wall of said whirling tank, the water containing air bubbles further generating a turbulent whirl and moving the foam with protein impurities up and passing said outlet connector and the central vertical foam inlet pipe of said protein foam collecting cylinder and then overflowing from the upper end of said foam inlet pipe into said protein foam collecting cylinder to complete the collection and removal of the protein impurities; the water processed by said protein foam remover flowing from the lower base of said protein foam remover to the backflow pipe, and then to the incoming chamber of said water flow buffer connected to said diversifying pipe; the water flow in the incoming chamber further overflowing through said central partitioning wall into said air bubble removing chamber, and finally isolating the air bubbles in the water by said air bubble isolating layer, so that the processed water without air bubbles flowing through the groove hole at the bottom of said air bubble removing chamber back into the aquarium.
