as shown in figures 1 to 6 of the drawings,
a backwash lamination type water distributor comprises a base 1, wherein a water inlet connecting part 11 is arranged at the lower part of the base 1, a matching part 12 is arranged on the base 1, a lamination frame 2 for containing filter materials is arranged on the matching part 12, water through cavities 2a are uniformly arranged on the lamination frame 2, a lamination group formed by overlapping a plurality of laminations 3 is sleeved outside the lamination frame 2, adjacent laminations are folded to form a water outlet channel 3a, and a V-shaped elastic sheet 4 is arranged in each water outlet channel 3 a; a back washing sleeve 5 is arranged outside the lamination stack, the back washing sleeve 5 is in threaded connection with the upper part of the lamination stack 2, a back washing interface 51 is arranged on the upper part of the back washing sleeve 5, the back washing interface 51 is communicated with a back washing channel 5a in the back washing sleeve 5, and a water outlet 5b is arranged on the back washing sleeve 5; when water is distributed, the water outlet channel 3a is aligned with the water outlet 5b on the back washing sleeve 5 to form a water outlet passage; during back flushing, the back flushing sleeve 5 is rotated to rise, the water outlet channel 3a is staggered with the water outlet holes 5b on the back flushing sleeve 5, and meanwhile the back flushing channel 5a is communicated with the water outlet channel 3 a.
The water outlet holes 5b on the back washing sleeve 5 and the washing channel 5a are arranged at intervals.
In order to ensure the smoothness of water distribution, the sectional area of the V-shaped elastic sheet 4 is preferably smaller than one half of the sectional area of the water outlet channel 3 a.
One surface of the lamination 3 is provided with an assembling convex block 31, the other surface of the lamination 3 is provided with an assembling groove 32 matched with the assembling convex block 31, and the assembling convex block 31 is embedded into the corresponding assembling groove 32; the height of the assembling convex block 31 is larger than the opening height of the V-shaped elastic sheet 4.
And water passing concave cavities 33 are respectively arranged on two sides of the lamination 3, and the water passing concave cavities 33 corresponding to the adjacent laminations are involuted to form a water outlet channel 3 a.
The assembly convex blocks 31 are matched with the assembly grooves 32, so that the lamination group can form a whole, and the water passing concave cavities 33 corresponding to the upper surface and the lower surface of the adjacent laminations 3 are prevented from being staggered due to the rotation of the laminations 3; the height of the assembly convex block 31 is larger than the opening height of the V-shaped elastic sheet 4, so that the assembly convex block 31 is still positioned in the corresponding assembly groove 32 when the V-shaped elastic sheet 4 is opened in the backwashing process.
The upper end of the lamination frame 2 is provided with a protruding part 21, and a pressing part 52 matched with the protruding part 21 is arranged in the back washing sleeve 5.
