Description
Technical field
The utility model relates to a kind of gravity valveless filter of easy backwash.
Background technology
Filter tank is the object for filtering, have with the suspension removed in water, to obtain the lower water of turbidity, having plenty of the water for removing in mud, having obtained the mud that water content is lower.Valveless filtering pool is that one does not have valvular rapid filter, in running, water outlet water level keeps constant, water inlet water level then constantly rises with the loss of flood peak increase of filtering layer in suction pipe, when water level rises to siphon pipe pipe top, and when forming siphon, namely automatically starting filtering layer backwash, flushing waste water is discharged outside pond along siphon pipe.
The complex structure in existing filter tank, filtrate is in enclosed construction, handling difficulty, and pond body cost is higher simultaneously, when filter tank realizes backwash, can produce and bleed, cause the water yield to run off, and along with the prolongation of time, the water yield runs off and increases the weight of, time serious, owing to all intaking through siphon pipe loss, thus backwash cannot be realized.

The utility model solves the technical scheme that its technical problem adopts: a kind of gravity valveless filter of easy backwash, there is distribution channel, described distribution channel is connected with the water inlet of water inlet pipe, the delivery port of water inlet pipe is connected with filter, filter is arranged in water tank, water tank is provided with outlet pipe, is provided with siphoning installation in water tank, siphoning installation is connected with filter;
Filter includes water distribution baffle plate, and the lower end of water distribution baffle plate is provided with filter material layer, and filtrate adopts profile to be close to spherical, rough surface, and with corner angle, the lower end of filter material layer is provided with grid layer, and filter lower end is provided with gathering ground, and gathering ground is connected with connection canal;
Siphoning installation comprises siphon tedge, siphon tedge is connected with siphon down-comer, the exit of siphon down-comer is provided with back washing strength adjuster, siphon tedge is provided with auxiliary siphon tube, auxiliary siphon tube is provided with exhaust tube, exhaust tube is connected with the siphon destructing tube be arranged on siphon tedge, and then there is siphon destructive bucket the termination of siphon destructing tube;
The surfaces externally and internally of water inlet pipe and exhaust tube and siphon destructing tube is provided with watertight composition, watertight composition is coated with anti-corrosion layer, anti-corrosion layer makes pipeline not easily produce perforated phenomenon, guarantee automatic back-washing is effective, saving water resource, reduce costs, the cleaning performance of filter material layer is good, ensures that drainage is effective.
Further, described auxiliary siphon tube is provided with sealing device, sealing device makes siphon tedge there will not be gas leak phenomenon, ensures the vacuum in pipe, makes backwash and established backwash to be destroyed and to stop.
The beneficial effects of the utility model are: the utility model structure is simple, can automatic fitration automatically repeatedly rinse, convenient operation and management, easy to loading and unloading, pipeline corrosion resistance and good, not easily produce perforated phenomenon, reduce the water yield and run off, to realize backwash, backwash is effective, automatic effects is good, and saving water resource reduces costs.

Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
The gravity valveless filter of a kind of easy backwash as shown in Figure 1, 2, there is distribution channel 1, distribution channel 1 is connected with the water inlet of water inlet pipe 2, the delivery port of water inlet pipe 2 is connected with filter, filter is arranged in water tank 3, water tank 3 is provided with outlet pipe 4, be provided with siphoning installation in water tank 3, siphoning installation is connected with filter; Filter includes water distribution baffle plate 5, and the lower end of water distribution baffle plate 5 is provided with filter material layer 6, and the lower end of filter material layer 6 is provided with grid layer 7, and filter lower end is provided with gathering ground 8, and gathering ground 8 is connected with connection canal 9; Siphoning installation comprises siphon tedge 10, siphon tedge 10 is connected with siphon down-comer 11, the exit of siphon down-comer 11 is provided with back washing strength adjuster 12, siphon tedge 10 is provided with auxiliary siphon tube 13, auxiliary siphon tube 13 is provided with exhaust tube 14, exhaust tube 14 is connected with the siphon destructing tube 15 be arranged on siphon tedge 10, and then there is siphon destructive bucket 16 termination of siphon destructing tube 15; The surfaces externally and internally of water inlet pipe 2 and exhaust tube 14 and siphon destructing tube 15 is provided with watertight composition 17, watertight composition 17 is coated with anti-corrosion layer 18, auxiliary siphon tube 13 is provided with sealing device.
Water in concrete distribution channel 1 enters filter via water inlet pipe 2, and the water after filtration enters water tank 3 by being communicated with canal 9 and purifying waste water from outlet pipe 4 discharge; When filter material layer 6 residue is more, when resistance becomes large, water is risen by siphon tedge 10, when water level reaches auxiliary siphon tube 13 mouth of pipe, from then on water just sharply fall in pipe, and taken away by the air in siphon pipe, make to form vacuum in pipe, siphon tedge 10 middle water level continues to rise.Now the water in trapped well 19 also sucts to certain altitude by siphon down-comer 11, and when the aqueous phase risen in water in siphon tedge 10 and siphon down-comer 11 converges, namely siphon is formed, and current are just gone out mouth of pipe inflow trapped well 19 and discharged, and namely backwash starts.Because siphon flow is 6 times of flow of inlet water, once siphon is formed, the water of water inlet pipe 2 is brought into siphon pipe immediately, and in water tank 3, water is also immediately by being communicated with canal 9 along filtering contrary direction, from bottom to up through filter tank, automatically rinses.Flushing water flows in trapped well 19 through siphon tedge 10 and discharges.When water tank 3 middle water level drops to below siphon destructive bucket 16 edge mouth, siphon destructing tube 15 is about to water extinction in bucket, and the mouth of pipe surfaces, and air is just a large amount of enters siphon pipe by siphon destructing tube 15, and destroy siphon, namely backwash stops, and filters and opens again
Above-mentioned embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
