And collection sand tube, with the delivery port conducting of described first row sand tube, second row sand tube, the 3rd sand discharge pipe, its one end is closed, and one end open, openend is provided with the 5th valve.
Adopt the beneficial effect of the technical program:
The utility model is by arranging multistage filter screen, to the foreign material classification filtering of different shape and particle diameter size, ensure the normal work of follow-up sprinkling irrigation equipment, the design of multistage filter screen it also avoid the blocking of filter screen itself, simultaneously, by the foreign material of sand discharge pipe scavenger precipitation before filter screen, reduce the blocked risk of filter screen further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of another embodiment of the utility model.
Detailed description of the invention
In order to better understand the utility model, below in conjunction with accompanying drawing, the utility model is further elaborated.
Please refer to Fig. 1, a kind of multistage filtering water pipeline, comprising: water pipe 1, and its water outlet is provided with the 4th valve 11; One-level filter screen 2, to be arranged in described water pipe 1 and near its inlet end; Secondary screen 3, is arranged at the centre position in described water pipe 1; Three grades of filter screens 4, to be arranged in described water pipe 1 and near its water outlet end; The mesh size of one-level filter screen 2, secondary screen 3 and three grades of filter screens 4 reduces successively.
Preferably, described multistage filtering water pipeline also comprises: first row sand tube 5, its water inlet and described water pipe 1 conducting, and between the water inlet and described one-level filter screen 2 of water pipe 1, its delivery port is provided with the first valve 51.
Preferably, described multistage filtering water pipeline also comprises: second row sand tube 6, its water inlet and described water pipe 1 conducting, and between described one-level filter screen 2 and secondary screen 3, its delivery port is provided with the second valve 61.
Preferably, described multistage filtering water pipeline also comprises: the 3rd sand discharge pipe 7, its water inlet and described water pipe 1 conducting, and between described secondary screen 3 and three grades of filter screens 4, its delivery port is provided with the 3rd valve 71.
During normal work, first valve 51, second valve 61 and the 3rd valve 71 are in closed condition, 4th valve 11 is in open mode, one-level filter screen 2, in secondary screen 3 and three grades of filter screens, 4 pairs of water, foreign material filter successively, larger particles diameter foreign material are deposited in first row sand tube 5 by one-level filter screen 2 filtering, comparatively small particle diameters foreign material are deposited in second row sand tube 6 by secondary screen 3 filtering, more small particle diameters foreign material are deposited in the 3rd sand discharge pipe 7 by the filtering of three grades of filter screens 4, periodic cleaning first row sand tube 5, foreign material in second row sand tube 6 and the 3rd sand discharge pipe 7, during cleaning, open the first valve 51, second valve 61 and the 3rd valve 71, close the 4th valve 11, be deposited on foreign material in sand discharge pipe and water pipe 1 downstream stream be discharged.
Please refer to Fig. 2, is another embodiment of the present utility model, and unique difference of itself and above-described embodiment is: also comprise: first-level filtering net net 21, secondary screen subnet 31 and collect sand tube 8.
First-level filtering net net 21 is arranged at the water inlet of described second row sand tube 6, in the same size with the mesh of described one-level filter screen 2.
