The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
as shown in Figures 1 to 4, a kind of structure improved sand filtration cylinder of the present utility model, comprise cylinder body 1, water inlet pipe 11 and water producing pipe 12, described water inlet pipe 11, described water producing pipe 12 is connected with described cylinder body 1 respectively, also comprise the upper water distributor 2 and the lower water-dispensing device 3 that are arranged at cylinder body 1 inside, described upper water distributor 2 is connected with described water inlet pipe 11, described lower water-dispensing device 3 is connected with described water producing pipe 12, described lower water-dispensing device 3 comprises water collector 31 and collector pipe 32, described water collector 31 is connected with water producing pipe 12, described collector pipe 32 is connected with water collector 31, described collector pipe 32 is provided with several drain ports 321.
in use, pending source water enters into upper water distributor 2 from water inlet pipe 11, then the delivery port from upper water distributor 2 flows out, source water from top to bottom flows through filtering medium layer equably, the collector pipe 32 that arranges through lower water-dispensing device 3 is again collected and is converged to water collector 31, because collector pipe 32 is provided with several drain ports 321, current are divided into numerous sprouts and enter collector pipe 32 by drain port 321, collect the phenomenon that effectively to avoid turbulent flow and sinuous flow when producing water, avoid the suspension in water, colloid thing and other foreign matter enter collector pipe 32, make and produce water turbidity less than 1NTU, carry the filter effect of high yield water.
In the present embodiment, the length of described drain port 321 is 20-30mm, and the width of described drain port 321 is 0.02-0.03mm.Through overtesting, adopt the drain port 321 of this dimensional structure, when current are divided into numerous sprouts, each sprout and drain port 321 have contact area preferably, the flow velocity of each sprout is more stable, even, can reduce better the phenomenon of turbulent flow and sinuous flow, and filter effect is better.
