Specific embodiment
The utility model is as shown in Figs 1-4, including tank body 1, upper water distribution screen casing 2, lower receipts water sieve pipe 3 and setting are in lower receipts
Double-layer filter material 4 on water sieve pipe 3, the upper water distribution screen casing 2 include several upper screen casing tube bodies 21 uniformly arranged；
The tank body 1 is equipped with hollow water inlet pipe 5；The water inlet pipe 5 is vertically arranged, and top is equipped with to be connected with sewage pipe
The flange connect, bottom are closed and are protruded into the tank body 1 from the top of the tank body 1；
Centered on the axis of the water inlet pipe 5, level is uniformly fixed at described several upper screen casing tube bodies 21
In tank body 1；
Several upper screen casing tube bodies 21 are equipped with several hole for water sprayings 22；Spacing between the adjacent hole for water spraying 22 is by interior
And successively successively decrease that (spacing between the adjacent hole for water spraying 22 refers to the inside from the center of tank body 1 to tank body 1 from inside to outside outside
The direction of wall).
Upper screen casing tube body 21 is centered on the axis of water inlet pipe 5, as shown in Fig. 2, being arranged radially, several upper screen casing pipes
The length and diameter of body 21 is equal, solves in the prior art that upper screen casing tube body 21 is limited by the space of 1 inner cavity of tank body, occurs
It is different in size, processing it is cumbersome, replacement poor universality the problems such as.Improve the versatility of 21 later maintenance of screen casing tube body.
Successively successively decrease in direction of the spacing from the center of tank body 1 to the inner sidewall of tank body 1 between the adjacent hole for water spraying 22；
Since the spacing between adjacent upper screen casing tube body 21 is incrementally increased from center to the inner sidewall direction of tank body 1, pass through hole for water spraying 22
Between spacing setting, it is ensured that the uniformity of sprinkling, improve double-layer filter material 4 adsorption efficiency.
The water inlet pipe 5 includes the water inlet tube body 51 and pedestal 52 being fixedly connected sequentially from top to down；Intake tube body 51 with
It is welded and fixed between tank body 1, sealing ring is equipped in pedestal 52, be detachably connected, be convenient for by screw thread and the water inlet fixation of tube body 51
Maintenance replacement, reduces replacement cost.
The water inlet tube body 51 is vertically fixed on the tank body 1；The top of the pedestal 52 and the water inlet pipe
Body 51 is detachably fixed sealed connection；The bottom of the pedestal 52 is equipped with the lid for being detachably fixed sealed connection, by the bottom
The sealed bottom of seat 52；
The periphery of the pedestal 52 is equipped with several connection pipe body 6 uniformly arranged；It stretches one end of the connection pipe body 6
Enter in the tank body 1, is connected to the inner cavity of the tank body 1；The other end of the connection pipe body 6 passes through ring flange and the upper sieve
One end of pipe tube body 21 is detachably fixed connection；
Several positioning plates 7 being fixedly connected, several positioning are equipped with close to top position on the inner sidewall of the tank body 1
