As shown in fig. 1 and 6, a high-efficiency back-washing-free high-precision filter comprises a shell 1 and a filtering mechanism installed in the shell 1, wherein the filtering mechanism comprises more than three layers of laminated perforated plates 2, the perforated plates 2 are uniformly provided with filtering holes 201 with the aperture larger than the diameter of the largest particulate matter to be filtered, the distance D between the centers of the adjacent filtering holes 201 is larger than or equal to twice the diameter D of the filtering holes 201, the perforated plates 2 are provided with pre-pressing mechanisms 3, the adjacent perforated plates 2 are connected in a sliding and tight manner through the pre-pressing mechanisms 3, the two adjacent filtering holes 201 are staggered with each other to form more than two filtering holes 4 with different apertures through relative staggered movement between the adjacent perforated plates 2, and the filtering holes 4 are communicated to form a filtering channel.
Through setting more than three layers of overlapped perforated plates 2 and correspondingly setting the aperture and the interval of the filter holes 201, after the perforated plates 2 move relatively, the filter holes 201 are mutually staggered to form filter holes 4 with different apertures, so that the filter holes 201 between the adjacent perforated plates 2 are mutually staggered and only partially overlapped, one part of the lower filter hole 201 is blocked by the non-filter hole 201 area of the upper perforated plate 2, the other part of the lower filter hole 201 is communicated with the filter hole 201 of the upper perforated plate 2 to form a filter hole 4 capable of passing through the filter, and the diameter of the overlapped and communicated part of the filter hole 201 of the upper perforated plate 2 and the filter hole 201 of the lower perforated plate 2 can be adjusted according to the moving distance of the upper perforated plate 2 relative to the lower perforated plate 2, namely, the aperture size of the filter hole 4 is adjusted, the aperture of the filter hole 4 is also adjusted by the same principle by the lower perforated plate 2 and the lower perforated plate 2, finally, a filtrate channel is formed through the communicated filtrate holes 4 from top to bottom. The distance D between the centers of the adjacent filtering holes 201 is more than or equal to two times of the diameter D of the filtering holes 201, so that the filtering holes 4 can completely penetrate to completely cover, namely the filtering holes 201 are equal to the filtering holes 4 when the aperture of the filtering holes 4 is the largest, and are zero when the aperture of the filtering holes is the smallest, in the adjusting process of the filtering holes 201 of the upper layer and the lower layer, the filtering holes 201 beside the filtering holes are not influenced, and the fact that one filtering hole 201 of the upper layer can only be overlapped with one filtering hole 201 of the lower layer is guaranteed; and the condition that one filtering hole 201 on the upper layer and more than two filtering holes 201 on the lower layer are provided with superposed and communicated filtrate holes can not occur, so that the adjustment of the filtrate holes is not accurate, and the layered filtering of the particulate matters is also influenced.
When filtering, filtrate firstly passes through a filtrate hole 4 formed by the overlapped part of a filter hole 201 of the topmost perforated plate 2 and a filter hole 201 of the next perforated plate 2, so that larger particles are firstly filtered, filter residues are left on the topmost perforated plate 2 and in the filter holes 201 of the topmost perforated plate 2, the filtrate enters the filter hole 201 of the next perforated plate 2, smaller particles in the filtrate are further filtered through the filtrate hole 4 formed by the next perforated plate 2 and the next lower perforated plate 2, and by analogy, the filtrate finally flows out through the filter hole 201 of the bottommost perforated plate 2, so that the particles in the material are filtered layer by layer according to particle diameters according to a fed particle distribution diagram, the purposes of adjusting and filtering with high precision are achieved, and a set of devices can easily obtain multiple required filtering precisions; the filter holes 201 are prevented from being blocked quickly when filter residues are accumulated beside the filter holes 201 due to the single-layer filter holes 201, the efficiency is extremely low, particularly for high-precision filtration, the single-layer filter holes 201 can cause various levels of particulate matters to be accumulated beside the tiny filter holes 201 quickly and block the filter holes 201 quickly, the filtration operation is difficult to carry out, and the high-precision filtration effect is more difficult to achieve; and this embodiment reasonable design filters hole 201 aperture and interval, and the rethread adjusts 2 displacements of multilayer perforated plate and forms multilayer filtrating hole 4, has realized high accuracy filtration and convenient washing, and the filter fineness reaches 5 mu m. The number of piles at perforated plate 2 is many, and the 4 numbers of piles in required filtrating hole do not need so much, can only use wherein several layers of perforated plate 2 to stagger, form the 4 numbers of piles in required filtrating hole, the filtration pore 201 of remaining layer perforated plate 2 overlaps completely or has most to overlap the filtration pore 201 or the filtrating hole 4 in big aperture that forms complete running through, thereby make things convenient for the filtrating to derive, reduce unnecessary filtration level, promote filtration efficiency.
As shown in fig. 6, the aperture of the filtrate hole 4 is gradually reduced from top to bottom, and by adjusting the multi-layer perforated plate 2, a filtrate channel with the aperture of the filtrate hole 4 gradually reduced from top to bottom is formed, so as to form a filter layer with a loose upper part and a tight lower part, thereby not only ensuring the filtering precision, but also increasing the dirt receiving capacity.
In the embodiment, when a certain amount of filter residues are accumulated in the filter structure, the water source can be directly connected for washing, the perforated plates 2 are moved to the original position, the filter holes 201 of the multi-layer perforated plates 2 are completely overlapped to form a filter liquid channel of the filter holes 201 which completely penetrate through, and the aperture of the filter holes 201 is larger than the diameter of the largest particulate matter to be filtered, so that the filter residues retained in the filter holes 201 staggered with the perforated plates 2 in the moving and resetting process can be pushed away along with the movement of the perforated plates 2 and then can flow along the penetrating filter holes 201, while the top of the perforated plate 2 at the topmost layer can flow along the overlapped filter holes 201 by water flow scouring, thereby achieving the effects of convenient and rapid cleaning, achieving the effects of small aperture filtering and large aperture cleaning, ensuring that the cleaning flow is simpler, convenient and more thorough, and the garbage of the perforated plate 2 at the middle layer is pushed out along the penetrating filter holes 201, basically, the water consumption is greatly reduced, and the time consumption for cleaning is also greatly shortened, so that the production efficiency is improved; the whole process does not need to use back washing, a back washing water pump and a back washing fan are not needed, a large amount of back washing water is not needed, a large amount of water resources are saved, the filtering structure can be protected, the filtering structure is prevented from being damaged or even easily loosened or damaged due to the fact that the filtering structure is washed by the back washing water in a transition mode, and therefore the service life of the filtering structure is prolonged.
In the process of adjusting the aperture of the filtrate hole 4, the perforated plate 2 can be moved manually or electrically. In addition, the pre-pressing mechanism 3 can further ensure the tightness between the filtering structures, and the perforated plate 2 can be further pressed through the pre-pressing mechanism 3 after the filtering structures are used for a period of time, so that the tightness and the stability between the perforated plates 2 are further ensured. In addition, the embodiment does not need to use expensive filtering materials and instruments, does not need to frequently replace the filtering materials, breaks through the technical problem of backwashing which is difficult to get rid of in the high-precision filtering industry by using the simplest materials, and achieves the maximum benefit with the lowest cost.
The CPU used in the control module 5 in this embodiment is of a model of SIMATIC S7-1200, the turbidity detector 13 is of a model of Ts-Line sc, and the differential pressure sensor is of a model of TPT 1298B.
