[0045] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0046] The core of the utility model is to provide a non-smooth straight lamination, by setting grooves and convex ribs on the upper and lower surfaces of the lamination, forming tiny filter channels through the cooperation of the grooves and convex ribs, and the combination of the grooves and convex ribs of adjacent laminations, the stacking thickness of the lamination can be effectively reduced, and more laminations can be added in a unit volume, the number of filter channels is increased, and the filtering efficiency is improved.

[0047] Another core of the utility model is to provide a lamination filter structure comprising the above-mentioned non-smooth straight lamination, which has the same technical features and can solve the same problem.

[0048] Still another core of the utility model is to provide a pre-filter comprising the above-mentioned non-smooth straight lamination, which has the same technical features and can solve the same problem.

[0049] Referring to Figures 1-4 A non-smooth straight lamination, the upper surface and the lower surface of the lamination 2 are both provided with a plurality of groups of grooves 21 and convex ribs 22 at intervals; the grooves 21 are connected to the two side edges of the lamination 2;

[0050] When two groups of laminations 2 are stacked, the grooves 21 and the convex ribs 22 between the two groups of laminations 2 can be embedded in each other, and the gap between the side walls of the grooves 21 and the side walls of the convex ribs 22 forms a filtering channel 23, which is consistent with the direction of the grooves 21;

[0051] As shown in Figure 1 and Figure 2 , the upper and lower surfaces of the lamination 2 are both provided with grooves 21 and convex ribs 22 at intervals, and as shown in Figure 1 , the top of the convex rib 22 is a gentle arc, and the bottom of the groove 21 is a relatively narrow channel. When laminations 2 of this type are stacked, the side walls of the convex rib 22 and the side walls of the groove 21 abut, and the filtering channel 23 is formed between the top of the convex rib 22 and the bottom of the groove 21. The water flow can pass through the filtering channel 23, thereby being filtered, and the impurities in the water flow are intercepted because the cross section of the impurities is larger than the cross section of the filtering channel 23, or are adsorbed by the surface of the lamination 2 on the side wall of the filtering channel 23 and remain on the surface of the lamination 2, thereby ensuring the filtering effect of the lamination 2;

[0052] Moreover, when the laminations 2 are stacked, the convex rib 22 of the upper lamination 2 is inserted into the groove 21 of the lower lamination 2, that is, the two laminations 2 partially overlap in the direction of their normal lines, and the stacking thickness of the two laminations 2 is less than the sum of the thicknesses of the two laminations 2, thereby enabling more laminations 2 to be stacked in a unit volume, generating more filtering channels 23, and thereby improving the filtering efficiency;

[0053] In some embodiments, the top of the convex rib 22 of the lamination 2 is a narrow structure, and the bottom of the groove 21 is a gentle arc. When the laminations 2 are stacked, the top of the convex rib 22 abuts the bottom of the groove 21, and the filtering channel 23 formed between the side wall of the convex rib 22 and the side wall of the groove 21 is crescent-shaped as shown in Figure 4 , which can also allow water flow to pass through and filter impurities in the water flow, and can further increase the amount of overlap of the laminations 2 in the direction of their normal lines when stacked.

[0054] In the present embodiment, the lamination 2 adopts a circular ring structure, and the filtering channels 23 are arranged along the radial direction of the lamination 2. In some embodiments, the lamination 2 adopts a long strip structure, and the filtering channels 23 are arranged along the length direction or the width direction of the lamination 2, which also belongs to the protection scope of the present application.

[0055] In some embodiments, the protrusion height of the convex rib 22 is equal to the recess depth of the groove 21, and the cross-sectional area of the convex rib 22 is smaller than the cross-sectional area of the groove 21;

[0056] As shown in Figure 4 When the protrusion height of the convex ribs 22 and the recess depth of the grooves 21 are equal, the two groups of laminates 2 can abut the bottom of all the grooves 21 and the top of all the convex ribs 22 when stacked, so that the cross section of all the filter channels 23 is the same, the filtering effect of each position of the laminates 2 is consistent, and the stability of the laminates 2 after stacking is ensured.

[0057] In some embodiments, the laminates 2 are circular ring structures, the length direction of the grooves 21 and the convex ribs 22 are arranged along the radial direction of the laminates 2, the grooves 21 and the convex ribs 22 are arranged in a ring array about the center line of the laminates 2, and the cross-sectional area of one end of the grooves 21 and the convex ribs 22 close to the center is smaller than that of the other end;

[0058] As shown in Figure 1 and Figure 2 The design of the laminates 2 in a ring structure can facilitate the arrangement of water channels of the filter and increase the number of filter channels 23 in a unit volume.

[0059] At the same time, due to the structure of the circular ring, the circumference of the inner ring is smaller than that of the outer ring, so that the cross-sectional area of the inner ring of the filter channels 23 is smaller than that of the outer ring, that is, the cross-sectional area of the filter channels 23 gradually decreases from the outside to the inside. When the water flow flows from the outside to the inside, the water flow continuously contacts the side wall of the filter channels 23, which helps to adsorb the tiny impurities in the water flow on the surface of the laminates 2, thereby improving the filtering effect of the water flow.

[0060] In some embodiments, the laminates 2 are ring structures, and the inner ring wall is provided with a slope 24;

[0061] As shown in Figure 3 When the slope 24 is arranged on the inner ring wall of the laminates 2, when backwashing is performed, the water flow flows from the inner ring to the outer ring, as shown in Figure 8 When the water flow impacts the slope 24, the impact force F of the water flow is dispersed into a downward component force F2 and an upward component force F1 along the surface of the slope 24, wherein the component force F2 drives the laminates 2 where the slope 24 is located to move downward, and the component force F1 acts on the laminates 2 in the upper layer to move upward, thereby increasing the gap between the laminates 2 on both sides, and the backwashing water flow quickly flushes the surface of the filter channels 23 and the laminates 2, and at the same time, since the impurities are adsorbed on the surface layer when the laminates 2 filter the water flow, the backwashing water can flush the surface layer of the laminates 2, and thus the impurities are more easily carried away by the backwashing water, thereby restoring the laminates 2 to the initial state, that is, prolonging the service life of the laminates 2.

[0062] In addition to the non-smooth straight-laced laminates disclosed in the above embodiments, as shown in Figures 5-7 The utility model also provides a laminate filtering structure, which comprises a plurality of groups of the above-mentioned non-smooth straight-laced laminates stacked along the normal direction of the laminates, and the convex ribs 22 and the grooves 21 of the laminates 2 of adjacent two groups are embedded with each other.

[0063] In some embodiments, a water distributor 1 and a frame 4 are also included;

[0064] Several sets of stacked pieces 2 are stacked along their own normal and then slidably installed with the frame 4. The sliding direction of the stacked pieces 2 is consistent with the stacking direction of the stacked pieces 2. One end of the frame 4 is provided with a limiting component to restrict the sliding of the stacked pieces 2.

[0065] The water distributor 1 is fixedly connected to the other end of the frame 4 to restrict the sliding of the stacked plates 2, and the water distributor 1 is used to evenly distribute water to one side of the stacked plates 2.

[0066] like Figure 5 As shown, by setting the skeleton 4, the stacked pieces 2 are guided to ensure that the stacked pieces 2 are stacked neatly, and the water distributor 1 and the limiting component are used to limit the stacked pieces 2 from both ends to ensure that the relative positional relationship between the stacked pieces 2 and the skeleton 4 is stable.

[0067] Furthermore, a water distributor 1 is used to distribute water evenly, ensuring that the water pressure is consistent at all positions of the stacked discs 2, thereby improving filtration efficiency.

[0068] In some embodiments, the device further includes a pressure cap 3 and an elastic element 5. The pressure cap 3 and the frame 4 are slidably mounted, and the elastic element 5 is provided between the pressure cap 3 and the frame 4 along the relative sliding direction. The sliding direction of the pressure cap 3 is consistent with the stacking direction of the stacked pieces 2.

[0069] The stacked plate 2 is positioned between the pressure cap 3 and the water distributor 1;

[0070] By setting the pressure cap 3 and the elastic element 5, the axial compressive force when the stacked pieces 2 are stacked is increased, thereby making the stacked pieces 2 stacked compactly.

[0071] In some embodiments, the frame 4 is a cylindrical structure, and the cylindrical wall is provided with several sets of water passage holes;

[0072] The annular stacked piece 2 is fitted onto the outside of the skeleton 4, and the inner ring wall of the stacked piece 2 abuts against the outer ring wall of the skeleton 4.

[0073] Water distributor 1 connects to the outer cavity of the frame 4 at different times and can evenly distribute water to the outer cavity.

[0074] Both the water distributor 1 and the pressure cap 3 are ring structures and are coaxially mounted on the outside of the frame 4.

[0075] The outer periphery of the pressure cap 3 is provided with an impact surface for water flow impact, so that the pressure cap 3 compresses the elastic element 5 under the action of water flow impact.

[0076] like Figures 5-7 As shown, the frame 4 adopts a cylindrical structure, wherein the upper end of the inner cylinder is the water outlet, the upper end of the outer cylinder is the water inlet, and the lower end of the outer cylinder is the water outlet.

[0077] When normal water filtering is performed, the water diverter 1 is open at the upper end of the outer cylinder and closed at the lower end of the outer cylinder, and water flows into the inner cylinder through the filtering channel 23 and then flows out from the upper end of the inner cylinder;

[0078] When backwashing is performed, the backwashing water channel is open at the upper end of the inner cylinder, closed at the upper end of the outer cylinder, and open at the lower end of the outer cylinder, and water flows reversely through the filtering channel 23 into the outer cylinder and then flows out from the lower end of the outer cylinder, and when the water flows through the pressure cover 3, the water impacts the impact surface of the pressure cover 3, the elastic member 5 is compressed, and the pressure cover 3 moves downward, that is, the stacking thickness of the laminations 2 is increased, which helps to increase the gap between the laminations 2 after the water flows through the inclined surface 24 of the lamination 2, and thus the backwashing effect is improved.

[0079] In addition to the non-smooth straight-laced laminations disclosed in the above embodiments, the utility model also provides a pre-filter comprising the above non-smooth straight-laced laminations, and other parts of the pre-filter refer to the prior art, and will not be described herein.

[0080] The embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same or similar parts between the embodiments can be referred to each other.

[0081] The non-smooth straight-laced laminations, the lamination filtering structure, and the pre-filter provided by the utility model are described in detail. The principles and implementation manners of the utility model are described by applying specific examples, and the description of the above embodiments is only used to help understand the method and the core idea of the utility model. It should be pointed out that, for ordinary skilled persons in the technical field, some improvements and modifications can be made to the utility model without departing from the principles of the utility model, and these improvements and modifications also fall within the protection scope of the utility model claims.
