Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

The utility model provides a novel gravity type valveless filter, connect gas-water separation case 2 including flow distribution weir 1, the gas-water separation case lower extreme is direct to link to each other with inlet tube 3, inlet tube 3 stretches into flush tank 10 and communicates with each other with siphon tedge 12 lower part, 12 ports fixedly connected with double-deck drilling breakwater 4 of siphon tedge and filtering layer 5 and supporting layer 6 arrange in proper order in the below, just to supporting layer 6 below arranging back flush water pump 7 and fan 8 side by side in flush tank 10 bottom, 12 upper portions of siphon tedge are connected with siphon destruction pipe 11, siphon destruction pipe 11 one end stretches into the destruction fill in flush tank 10, the other end is that exhaust tube 14 branches connect siphon auxiliary 13 and 15 together stretch into drain well 16 in the time of siphon downpipe, drain well 16 links to each other with water seal weir 17 and links to each other with sewage pipe 18 again.

Raw water with certain turbidity enters a 2-gas-water separator through a 1-flow distribution weir, enters a 5-filter material layer through a 3-water inlet pipe and a 4-double-layer drilling baffle, and filtered water enters a 10-flushing water tank through a 9-communicating pipe and is discharged as purified water from a water outlet pipe. When 5-filtering layer has more material to be intercepted and the resistance is increased, the water rises from the 12-siphon ascending pipe, when the water level reaches the 13-siphon auxiliary pipe orifice, the water drops from the pipe sharply, and the air in the 12-siphon pipe is pumped away, so that the vacuum is formed in the pipe, and the water level in the 12-siphon ascending pipe continues to rise. At the moment, the 15-siphon descending pipe sucks the water in the 16-drainage well to a certain height, when the water in the 12-siphon ascending pipe is combined with the water ascending in the 15-siphon descending pipe, siphon is formed, water flows out of the pipe opening and flows into the 17-water sealing weir to be discharged, and backwashing is started. Because the 12-siphon flow is 6 times of the inflow flow, once the siphon is formed, the water from the water inlet pipe is immediately brought into the 12-siphon pipe, and the water in the 10-flushing water tank also immediately passes through the 9-communicating pipe along the opposite direction of the filtration and passes through the filter tank from bottom to top to automatically flush. Because the silt on the 5-filter layer is seriously deposited, the 7-back flush water pump and the 8-fan are started at the moment, the flushing force and the water flow rate are increased, the 4-double-layer drilling water baffle plate at the 6-supporting layer port is also used for preventing the filter material from losing in the flushing process, and the 7-back flush water pump and the 8-fan can be closed after the filter layer becomes thin. The flush water was drained through a 12-siphon riser to a 16-drain well. When the water level in the 10-water tank drops below the edge opening of the siphon breaking bucket, the 11-siphon breaking pipe absorbs light of the water in the bucket, the pipe opening of the 11-siphon breaking pipe is exposed out of the water surface, a large amount of air enters the siphon pipe through the 11-siphon breaking pipe, the siphon is broken, the backwashing is stopped, and the filtering is restarted.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
