The utility model provides a filter concentrator of a lamination stator and a variable diameter screw rod rotor. The filter concentrator adopts a filtration concentration form of the combination of the lamination stator and the variable diameter screw rod rotor. Because a pushing-pressing device of a variable diameter screw rod is used, the section area of a passage decreases along with the increase of the solution concentration and the reduction of the flow before the filtration. The variable diameter screw rod plays the role of real-time cleaning of a filtering surface and pressure supplement to the solution when the variable diameter screw rod rotates, satisfies non-stop continuous working requirements, and can perform precision filtration and concentration to various solutions including colloidal solutions even gas. Because the form of the lamination clearance filtration is adopted, the degree of tightness of the lamination can be adjusted by means of the adjustment of a nut, and thus the filtration preci
