The utility model relates to a composite laminated filter for adjusting tightness of a double-layer filter element, which is characterized in that multistage filtration is realized in two ways, firstly, two layers of filtration with different precision are realized by utilizing an outer-layer filter element 4 and an inner-layer filter element 5, when water flows enter a cavity through a water inlet 1 and a flow divider 22, larger particles are filtered through the outer-layer laminated element 4, and fine filtration is performed through the inner-layer laminated element 5, so that the phenomenon that water head loss is increased due to mismatching of filtration precision and water quality condition, and the influence of premature blockage of laminated elements on filtration effect can be prevented. Meanwhile, if the grain composition distribution in the water is concentrated, the outer layer filter element 4 or the inner layer filter element 5 can be taken out for single-layer filtration, and meanwhile, the tightness of the lamination can be controlled by adjusting the tightness of the outer layer filter element 4 and the inner layer filter element 5 and by compressing and releasing the hollow cylinder, the outer layer filter element 4 can be compressed and the inner layer filter element 5 can be released; the inner filter element 5 is pressed tightly, and the outer filter element 4 is loosened; the outer filter element 4 and the inner filter element 5 are simultaneously pressed; the hollow cylinder is adjusted according to different water qualities, so that the filtering range of the filter element is improved again, and the application range of the laminated filter can be greatly improved due to the two-layer design.
According to the composite laminated filter for adjusting the tightness of the double-layer filter element, the tightness of the outer-layer filter element 4 and the inner-layer filter element 5 can be adjusted by utilizing the rotation of the first motor 10 and the second motor 21, the gap rate of the inner-layer filter element and the outer-layer filter element is respectively controlled by two motors arranged at the upper end and the lower end of the device, a rotor of the second motor 21 is connected with one end of a coupling screw 19 through a speed reducer, the other end of the coupling screw 19 is connected with one end of a hollow cylinder 16, the other end of the hollow cylinder 16 is in direct contact with a laminated sheet, and the tightness of the laminated sheet is adjusted by the up-down displacement of the hollow cylinder. The hollow cylinder is connected with the cylinder body 2 through a fixed connecting rod 18, so that when the motor rotates, only linear displacement and no angular displacement are ensured. The same is true for the lower motor 10.

Wherein s is linear displacement, the unit is mm, w is angular displacement, the unit is DEG, p is thread diameter, and the unit is mm.
