As shown in fig. 1-5, taking two layers of filter screen plates as an example, there are a layer of filter screen plate and B layer of filter screen plate, and the a layer of filter screen plate and the B layer of filter screen plate are stacked together (as shown in fig. 5). When the A-layer filter screen plate and the B-layer filter screen plate are superposed and the filter holes are arranged in a crossed manner, the overlapped part of the filter holes 2 forms the filter screen holes 3 of the laminated filter, and when the laminated filter is used, the size of the filter screen holes 3 can be adjusted by adjusting the crossed area of the filter holes between the A-layer filter screen plate and the B-layer filter screen plate.

As shown in fig. 6-10, taking three layers of filter screen plates as an example, a layer of filter screen plate a, a layer of filter screen plate B and a layer of filter screen plate C, and are fixedly connected by fasteners 4 (as shown in fig. 6). When the layer A of filter screen plate, the layer B of filter screen plate and the layer C of filter screen plate are superposed and the filter holes 2 are not overlapped at all, the clearance between the filter screen plate A and the filter screen plate B and the clearance between the filter screen plate B and the filter screen plate C form the filter screen holes 3 of the laminated filter. When the filter screen is used, the size of the filter screen holes 3 can be adjusted by adjusting the gap between the adjacent filter screen plates 1, and the filtering efficiency can be changed by adjusting the gap between the two adjacent filter screen plates 1. It should be noted that the shape and size of the filter holes 2 in the filter screen plates 1 of different filter layers may be the same or different.

As shown in fig. 11-15, taking three layers of filter screen plates as an example, as shown in fig. 15, the layer a of filter screen plate, the layer B of filter screen plate and the layer C of filter screen plate are respectively arranged from top to bottom and are fixedly connected by a fastener 4. Wherein, the filtering holes 2 of the filtering net plate of the layer A and the filtering net plate of the layer B are completely arranged without overlapping, and the clearance between the filtering net plate A and the filtering net plate B forms the filtering sieve pores 3 of the laminated filter; when the B layer of filter screen plate and the C layer of filter screen plate are superposed and the filter holes 2 are arranged in a crossed manner, the superposed positions of the filter holes 2 form filter screen holes 3 of the laminated filter.

As shown in fig. 16-21, two layers of filter screen plates are taken as an example, which are an a layer filter screen plate and a B layer filter screen plate, wherein the a layer filter screen plate is provided with longitudinal bar-shaped holes, and the B layer filter screen plate is provided with transverse bar-shaped holes. It should be noted that, in practical applications, the direction of the strip-shaped holes is not limited, and the strip-shaped holes on the adjacent filter screen plates can be respectively arranged to be inclined left or right (as shown in fig. 27-29). The layer A and the layer B are respectively wound into a columnar filtering structure and stacked in a columnar form. When the layer A of filter screen plate and the layer B of filter screen plate are superposed and the filter holes are arranged in a crossed manner, the overlapped part of the filter holes 2 forms the filter screen holes 3 of the laminated filter.

As shown in fig. 22-26, the layer a filter screen plate and the layer B filter screen plate are provided, the layer a filter screen plate is provided with longitudinal strip-shaped holes, the layer a filter screen plate is provided with a planar plate 6, and the planar plate 6 is provided with longitudinal strip-shaped holes; a transverse strip-shaped hole is formed in the filter screen plate B, a plane plate 6 is arranged on the filter screen plate B, and a transverse strip-shaped hole is formed in the plane plate 6. It should be noted that, in practical application, the direction of the strip-shaped holes is not limited, and the strip-shaped holes on the adjacent filter screen plates can also be respectively arranged to be inclined left and right (as shown in fig. 27-29). The layer A of filter screen plate and the layer B of filter screen plate are wound to form a columnar structure at one end and a non-columnar structure at the other end. It should be noted that the non-cylindrical structure may be one of an arc, a circle, an ellipse, a polygon (e.g., a square, a diamond, a polygon, a triangle, a bar, etc.), and the like. As shown in fig. 30-31, the non-columnar structures are trapezoidal structures. It can be seen that the corresponding unfolded flat plate can be in the shape of circle, ellipse, polygon, etc. When the device is used, the parts with the columnar structures are sleeved together, and the parts with the non-columnar structures are naturally overlapped together.

It should be noted that the screen 1 may also be rolled into an arc-shaped configuration (not shown in the figures).

As shown in fig. 1 to 21, the filter holes 2 of the filter screen plate 1 may be circular, oval, polygonal, etc.

As shown in fig. 32 and 33, the filter screen plate 1 is provided with a positioning structure 5.

The positioning structure 5 can be a W-shaped groove, a V-shaped groove, a square groove, an arc-shaped groove and the like, the W-shaped groove and the W-shaped groove, the V-shaped groove and the V-shaped groove, the square groove and the square groove or the arc-shaped groove and the arc-shaped groove on adjacent filter screen plates are matched, and when the filter screen is used, the filter area can be increased on one hand through superposition, namely, the aperture of a filter screen hole is reduced; on the other hand, the positioning structure 5 has a positioning function, and can limit the relative displacement between the adjacent filter screen plates 1, so that the aperture of the filter screen holes 3 is fixed.

A filter material (not shown) such as a fiber fabric, a wire mesh, etc. for changing the filtering effect and the filtering efficiency is disposed between the adjacent filter screen plates 1 to increase the filtering effect. According to the practical application condition, the added filter material can be fixed on one or two adjacent filter screen plate layers by using a fastener; or fixing the filter screen plates on one or two adjacent filter screen plate layers by using a chemical coagulant such as dehydration and the like; or simply placed between two layers of filter screen plates without fixation.

It should be noted that the filter screen plate of the present invention can adopt the filtering principle of the existing screen hole type filter, for example:

(1) the adjacent filter screen plates are formed by overlapping, and when the filter screen plate is used, the purpose of accelerating the filtering speed can be achieved by pressurizing the filtered objects in the filtering process.

(2) The adjacent filter screen plates are sequentially wound into a columnar filter structure and are stacked in a columnar form. When in use, the purpose of accelerating the filtering speed can be achieved by pressurizing the filtered objects in the filtering process. Alternatively, the filter may be rotated during filtration, i.e. the filtration speed is increased by increasing the centrifugal force.

(3) When the filter screen plates are subjected to columnar nesting or other types of superposition, if temperature changes in the filtering process, the purpose of adjusting the layer gaps of the filter layers is achieved by selecting the filter layers made of materials with different thermal expansion coefficients.

The material of each filter layer of the utility model can be the same or different, and can be determined according to the actual use.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
