Abstract

The invention discloses a close rotary type filterable membrane device which includes a filterable tank, a dynamic unit, an axial tube unit and a plurality of filterable membrane units. The filterable tank has a close chamber, an water inlet, a water outlet and a control value. The axial tube unit is through set in the filterable tank, and at least one end extends to the filterable tank outside, the axial tube unit has a water generating port. The filterable membrane units are through set on outer wall of the axial tube unit with equal interval, the axial tube unit is drove by the dynamic unit, and then drives the filterable membrane unit rotating around an axial direction, a membrane of each filterable membrane unit is vertical set with the axial line.

Description

technical field

[0001] The invention relates to a closed water filtering device, in particular to a closed rotary membrane filter device which can tolerate relatively large sewage turbidity. Background technique

[0002] The reverse osmosis membrane group in the prior art includes a plurality of filter membranes sandwiched between two sheets with a mesh, and a water inlet net interposed between adjacent filter membranes. The above-mentioned components are also A concentric tube body wound on a central tube, the tube body is then placed in a ceramic shell, and a plug is used to block the position at both ends, forming a spiral-wrapped (spiral- wound) membrane tube, in which the sheet is only a membrane that can be dialyzed by water molecules (commonly known as RO membrane). The filter membrane is separated by a mesh to form a water production channel inside. Similarly, adjacent The filter membrane is sandwiched by the water inlet network to form a water inlet channel paralle...
