种鱼缸净水用水幕式过滤盒

本发明涉及种鱼缸水过滤方法以及以此方法实现的水幕式过滤盒。前述过滤方法包括以下步骤：首先，由水泵将鱼缸水抽入到过滤盒中进行过滤；其次，水流经倾斜设置的，下端边缘与鱼缸壁平行且与鱼缸壁之间留有狭长的，可调节宽度的缝隙的导流板引流至鱼缸壁上；再次，调节缝隙大小使水流均匀散布形成水幕；最后，形成水幕的水流回到鱼缸中重复参与上述循环。本发明还披露了过滤盒，包括盒体，导流板和固定装置，导流板倾斜设置在盒体出水口的下方，其下端边缘与玻璃平行，并与玻璃之间留有狭长缝隙，水流经导流板流至该狭长缝隙时，调节缝隙大小可使水流均匀分布形成水幕，实现发明目的。 The invention relates to a fish tank water filtering method and a water curtain type filter box implemented with the method. The filtering method comprises steps as follows: firstly, fish tank water is pumped into the filter box by a water pump and filtered; secondly, water is guided to the fish tank wall through an inclined guide plate, wherein the lower end edge of the guide plate is parallel to the fish tank wall and a narrow width-adjustable gap is reserved between the lower end edge of the guide plate and the fish tank wall; thirdly, water flow is distributed uniformly to form a water curtain through adjustment of the gap size; finally, water flow forming the water curtain returns to the fish tank for repeated circulation.
