Description
Technical field
The utility model relates to water filter, especially relates to a kind of high-efficiency fluid sand filter.
Background technology
At present; the common filter that is used for former water (trade effluent, sanitary sewage and tap water) filtration mainly is to filter by filtrate; although filtration device structure is fairly simple; but it is filtering the problem that has in service: the tiny filtering material particle in the filtered water can not be discharged when filtration is carried out simultaneously; need to shut down the backwash filtrate; thereby filter effect is not very good, and efficient is not high yet.And the reasonable strainer of filter effect, its structure is more complicated again, and cost and working cost are all higher.
The utility model content
For above-mentioned problems of the prior art, the utility model provides a kind of not only compact construction simple, easily manufactured, and the high-efficiency fluid sand filter of good filtration effect.
The technical scheme that the technical problems to be solved in the utility model is taked is: described high-efficiency fluid sand filter comprises tank body, described tank body top is cylindrical, the bottom is conical, the middle and lower part is provided with filtrate in tank body, be provided with the filtrate riser tube in the middle of in tank body, filtrate riser tube lower end is provided with the aerodynamic force switch room, filtrate riser tube upper end is provided with the backwash device and extend out to outside the tank body, be provided with divider at the filtrate riser tube, be provided with water inlet pipe on tank body top, described water inlet pipe upper end is positioned at the tank body top, water inlet pipe lower end and divider are connected, below divider, be provided with material guiding hopper, described material guiding hopper is tapered, be provided with filter on tank body top, described filter is connected with the rising pipe that is positioned at tank body top, described aerodynamic force switch room comprises first cavity and second cavity that movable sealing links to each other, be formed with a passage between described first cavity and second cavity, described first cavity links to each other with the sealing of filtrate riser tube, described ventpipe links to each other with passage, is provided with all-in-one-piece silk screen in passage.
Principle of work of the present utility model is: flocculation agent enters filter interior with former water through water inlet pipe, after the even distribution of divider, by filtrate in the process at upper reaches with former water mixed flocculation, filtrate is owing to being compressed the past current downflow of the effect of air-lift unit, more abundant and the former water of flocculation agent is mixed, because filtrate thickness reaches 2 meters, therefore flocculation agent is with after former water mixes, suspended substance in the former water can form jelly under the effect of flocculation agent, because jelly proportion is larger than water, precipitates under the effect that filtrate is held back.Along with the carrying out of filtering, the pollutent of holding back in the layer of sand of filter bottom increases gradually, under the compressed-air actuated effect that externally provides, the filtrate of filter bottom is promoted to filter top by the filtrate riser tube, filtrate is baffling in the backwash device, free-falling, in dropping process with the separated from contaminants of filter material surface, the sewage that washing produces is discharged from the sewage draining exit of strainer, and filtrate is cleaned up and falls back to sand top by the current that make progress in the backwash device, enter next time filtration cycle, water after the filtration collects in the filter on strainer top, and is entered in the rising pipe by overflow port and to discharge.
The utility model compact construction is simple, make easy for installation, the use reliability is strong, owing to adopting pressurized air that the contaminated filtrate of filter bottom is upwards promoted, the filtrate that pollutes in lifting process cleans, filtrate after the cleaning recycles, can make filtrate in filtration procedure, remain clean, and owing to adopting separable aerodynamic force switch room, but the silk screen monoblock type is inserted easily, solve existing collapsible silk screen and existed the slit to cause the problem of filter clogging inlet pipe, greatly improved filter effect.

Fig. 2 is I-I structure enlarged diagram among Fig. 1.
In the drawings, 1, aerodynamic force switch room 2, angle bar piece 3, material guiding hopper 4, divider 5, filtrate 6, tank body 7, backwash tube 8, water inlet pipe 9, filtrate riser tube 10, backwash device 11, ventpipe 12, filter 13, rising pipe 14, axial sealing ring 15, first cavity 16, silk screen 17, second cavity 18, passage 19, planar seal ring.
Embodiment
In Fig. 1 and Fig. 2, described high-efficiency fluid sand filter comprises tank body 6, described tank body top is cylindrical, the bottom is conical, the middle and lower part is provided with filtrate 5 in tank body, the filtrate height is two meters, be provided with filtrate riser tube 9 in the middle of in tank body, filtrate riser tube upper end is opened wide and is fixed on the water inlet pipe, filtrate riser tube lower end is provided with aerodynamic force switch room 1, filtrate riser tube upper end is provided with backwash device 10 and extend out to outside the tank body, the bottom filtrate that pollutes enters in the filtrate riser tube from the aerodynamic force switch room, be provided with divider 4 at the filtrate riser tube, former water Uniform Dispersion ground in the divider flows out, be provided with water inlet pipe 8 and backwash tube 7 at the tank body internal upper part, described water inlet pipe upper end is positioned at the tank body top, water inlet pipe lower end and divider are connected, below divider, be provided with material guiding hopper 3, described material guiding hopper is tapered, for improving the structural strength of material guiding hopper, prolong its work-ing life, in the material guiding hopper lower end, be provided with angle bar piece 2, be provided with filter 12 on tank body top, described filter is connected with the rising pipe 13 that is positioned at tank body top, described aerodynamic force switch room comprises first cavity 15 and second cavity 17 that links to each other with planar seal ring 19 movable sealings, be formed with a passage 18 between described first cavity and second cavity, described first cavity links to each other with axial sealing ring 14 sealings with the filtrate riser tube, described first cavity links to each other with ventpipe 11 lower ends, ventpipe communicates with passage, the ventpipe upper end extend out to outside the tank body and links to each other with air compressor, in passage, be provided with the all-in-one-piece silk screen 16 that stainless steel is made, described first cavity be connected cavity and connect with bolt, when silk screen is changed, unclamp bolt, first cavity is extracted, the monoblock type that makes is in advance justified the silk screen of simple shape and put into passage, again with first cavity and second cavity bolted, the aerodynamic force switch room is separable, thereby all-in-one-piece silk screen directly can be put into passage, because all-in-one-piece silk screen does not have the slit, filtrate can't enter in the ventpipe under suction function, solve existing monoblock type aerodynamic force switch room and can not use all-in-one-piece silk screen, can only use folding silk screen, make silk screen slit and dislocation occur, cause under suction function filtrate to enter and stop up ventpipe in the ventpipe, make pressurized air can't enter the aerodynamic force switch room filtrate that pollutes is promoted cleaning, reduced the problem of filter effect.
