Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1, a schematic structural diagram of a multistage integrated automatic backwashing sewage filtering apparatus is shown, which includes a primary filter tank 1, a secondary filter tank 2, and a high-efficiency filter tank 3 (the primary filter tank 1, the secondary filter tank 2, and the high-efficiency filter tank 3 are all made of PVC) that are coaxially stacked and hermetically communicated from top to bottom.
Referring to fig. 2, a sewage inlet 4 is arranged at the top of one side of the primary filter tank 1, a liquid level sensor 14 is arranged on the primary filter tank 1 below the sewage inlet 4, the left and right ends of the sewage inlet 4 are symmetrically communicated with horizontal diversion water pipes 5 made of PVC, one ends of the horizontal diversion water pipes 5 far away from the sewage inlet 4 are respectively communicated with horizontal deluge pipes 6 made of PVC (referring to fig. 3, rain pipe water outlets 601 are distributed in the horizontal deluge pipes 6 in a straight line shape), the horizontal deluge pipes 6 are vertically arranged relative to the horizontal diversion water pipes 5, stainless steel filter screens 8 are symmetrically arranged at 45 degrees in a left-right direction right below the two horizontal deluge pipes 6, the tops of the stainless steel filter screens 8 are fixedly abutted against the inner wall of the filter tank at the same side as the horizontal deluge pipes 6 right above, the bottoms of the stainless steel filter screens 8 are commonly connected with a precipitation sewage discharge tank 9 made of PVC, one end of the precipitation sewage discharge groove 9 is provided with a sewage discharge outlet 12, the precipitation sewage discharge groove 9 is in a U-shaped structure and is arranged in the middle of the stainless steel filter screens 8 at two sides, a backwashing water sprayer 10 (a water sprayer inlet 11 is arranged at one side of the backwashing water sprayer which can be selected to be a 0-120-degree hydraulic rotation backwashing water sprayer) is arranged right below the stainless steel filter screens 8, the backwashing water sprayer 10 is provided with a fan-shaped spray head 15, and the fan-shaped spray head 15 is arranged right opposite to the stainless steel filter screens 8.
Referring to fig. 1-2, clear water outlets 13 are distributed at the bottoms of the primary filter tank 1, the intermediate filter tank 2 and the high-efficiency filter tank 3; simultaneously, well imitate rose box 2 and high efficiency filter box 3 all are the open structure in top, and except not establishing sewage water inlet 4, transversely dividing water pipe 5, transversely drenching the pipe 6, the inner structure of well imitate rose box 2 and high efficiency filter box 3 is the same with just imitating rose box 1.
The working process is as follows: the sewage is drained from the sewage inlet 4 through the transverse diversion water pipe 5 to the water outlet 601 of the transverse deluge pipe 6 and flows out; solid particles in effluent sewage are blocked by a stainless steel filter screen 8 (with the mesh number of 200) of the primary filter tank 1 and flow downstream to a precipitation sewage discharge tank 9 of the primary filter tank 1, so that primary filtration is realized; the water body after the first filtration directly trickles from a clean water outlet 13 at the bottom of the primary filter tank 1 to a stainless steel filter screen 8 (with the mesh number of 400) of the intermediate filter tank 2 for the second filtration; the water body after the second filtration trickles to a stainless steel filter screen 8 (with the mesh number of 800) of the high-efficiency filter box 3 through a clean water outlet 13 at the bottom of the middle-efficiency filter box 2, is filtered for the third time, and flows out from the clean water outlet 13 at the bottom of the high-efficiency filter box 3.
In addition, when the stainless steel filter screens 8 of the primary filter tank 1, the intermediate filter tank 2 and the high-efficiency filter tank 3 are blocked by filter residues in sewage, and the liquid level sensor 14 senses that the water level rises, the liquid level sensor 14 feeds back a signal to the controller 7 of the device body (referring to fig. 2, the controller 7 can be arranged on the surface of the primary filter tank 1), so that the backwashing water sprayer 10 is started; and the fan-shaped spray head 13 of the backwashing water sprayer 10 is driven by water power to swing up and down at 120 degrees to sweep the stainless steel filter screen 8, the swept filter residues are collected in the precipitation and sewage discharge groove 9 and finally discharged through the sewage discharge water outlet 12, and backwashing of the primary-effect filter tank 1, the intermediate-effect filter tank 2 and the high-efficiency filter tank 3 is realized.
