The specific embodiment:
Embodiment:
Structural representation of the present utility model such as Fig. 1,2, shown in 3, include nozzle 1, connector 2, suction nozzle 3, suction nozzle seat 8, wherein the water inlet 1A of nozzle 1 is connected with the high service pipeline that process purifies, nozzle 1 with the corresponding position of cylindrical shape screen pack of automatic back-flushing filtering device on be provided with water jet 1B, nozzle 1 is installed on the suction nozzle 3, and be fastened on the suction nozzle 3 by connector 2, suction nozzle 3 is installed on the suction nozzle seat 8, and be fastened on the suction nozzle seat 8 by securing member 4, and the second mudhole 8A that makes on the first mudhole 3A that makes on the suction nozzle 3 and the suction nozzle seat 8 communicates, suction nozzle seat 8 is installed on the hollow rotating shaft of automatic backwash filter plant by the installing hole 8B of a fluting, and hollow rotating shaft communicates by the second mudhole 8A that makes on the circular hole that has on it and the suction nozzle seat 8.In the present embodiment, the water inlet 1A of said nozzle 1 is a waist circular port.The water jet 1B of said nozzle 1 is the rectangular opening of a thin-and-long, and this rectangular opening becomes an acute angle with its cross section, shown in Fig. 4,5,6.Said suction nozzle 3 seals by sealing ring 7 with the contact-making surface of suction nozzle seat 8.The first mudhole 3A that makes on the suction nozzle 3 is used to draw impurity on the cylindrical shape screen pack, foul etc., when equipment moves, pass through action of pressure, meetings such as the impurity on the obstruction cylindrical shape screen pack, foul are drawn in the mudhole of suction nozzle automatically, and the blow-off line by other discharges then.The water jet 1B of nozzle 1 is owing to be the rectangular opening of a thin-and-long, and this rectangular opening becomes an acute angle with cross section, like this through the water under high pressure after purifying when rectangular opening ejects, can blow afloat with sticking to impurity on the cylindrical shape screen pack, foul etc., be beneficial to suction nozzle it sucked.
Also be equiped with between said suction nozzle 3 and the suction nozzle seat 8 and adjust pad 6.Adjusting pad is used for adjusting nozzle and suction nozzle and arrives distance between the cylindrical shape screen pack, when real work, need be according to concrete service condition, select the distance an of the best, reaching the best effects of suction nozzle suck up impurity, and will stick to impurity on the cylindrical shape screen pack, foul etc. from the high-pressure hydraulic that nozzle ejection is come out and blow afloat.
In the present embodiment, above-mentioned sealing ring 7 is the O RunddichtringO.The diameter of the second mudhole 8A that makes on the diameter of the first mudhole 3A that makes on the said suction nozzle 3 and the suction nozzle seat 8 is identical.Above-mentioned connector 2 is the holding screw of awl end for upper end fluting, lower end.Above-mentioned securing member 4 is a hex bolts, and locking spring washer 5 is housed on it.
In addition, scribble bonding agent around the contact-making surface between said nozzle 1 and the suction nozzle 3.In case leak-stopping water.
During the utility model work, washer is installed on the rotating shaft of automatic backwash filter plant, and this rotating shaft rotates on the one hand, can do rectilinear motion vertically on the other hand.When equipment work moves, if stick to impurity on the cylindrical shape screen pack, foul etc. too much, the hydraulic pressure before this spline filter with filter after hydraulic pressure will be different, when pressure differential reaches the parameter of setting, washer is just started working, to realize that the cylindrical shape screen pack is carried out two-sided automatic cleaning.Washer in the roughly process of doing cleaning is: through the rectangular opening of the water under high pressure after purifying by thin-and-long in the nozzle, blow afloat with sticking to impurity on the cylindrical shape screen pack, foul etc.By the mudhole in the suction nozzle, because action of pressure is drawn into impurity, foul etc. in the suction nozzle automatically, the blow-off line by other discharges at last then.Because washer rotates,, so just can realize cleaning on one side to the overall cylindrical screen pack Yi Bian do rectilinear motion vertically on rotating shaft.When washer is worked, do not influence the filtering function of automatic backwash filter plant, just continue to flow.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, do not breaking away under the prerequisite of the present utility model; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
