Description
Technical field
The utility model relates to a kind of gas stripping type desander for rotational flow grit pit.
Background technology
Sewage disposal is the water quality requirement making sewage reach a certain water body of draining or reuse, and to the process that it purifies.Sewage disposal is widely used in building, agricultural, and the every field such as traffic, the energy, petrochemical industry, environmental protection, urban look, medical treatment, food and drink, also come into the daily life of common people more and more.
And in sewage disposal process, setting pot is requisite important component part in all kinds of sewage disposal device.Due to sewage migration, flowing and collecting in process is inevitably mixed into silt particle, if the sand in sewage not sedimentation separation in advance remove, then can affect the operation of subsequent processing device.Setting pot, based on Gravity Separation, by controlling the water inlet flow velocity of setting pot, heavy inorganic particle is sunk, and organic suspension particle can be taken away with current.Existing setting pot desanding, what usually adopt is sand sucker, when the silt deposited in setting pot reach a certain height, just needs to use sand sucker to be extracted out bottom setting pot by silt.Traditional sand sucker complex structure, complex operation desanding effect is undesirable.
Utility model content
For the problems referred to above, the utility model proposes a kind of gas stripping type desander for rotational flow grit pit.
For solving this technical problem, the utility model takes following scheme: a kind of gas stripping type desander for rotational flow grit pit, comprise pond body and cover plate, pond body comprises point constituency being located at top, the Ji Shaqu being located at middle part and is located at the sand collecting hopper of bottom, and point constituency sidewall offers water inlet and delivery port; Described pool center axle is vertically arranged with hollow paddle driving tube, and paddle driving tube inner chamber is provided with air inlet pipe and sediment outflow pipe, and sediment outflow pipe is positioned at paddle driving tube lumen centers; Described air inlet pipe and sediment outflow pipe one end are all near the bottom of sand collecting hopper, and air inlet pipe and the sediment outflow pipe other end all pass pond body; Described paddle driving tube lower horizontal is axially provided with paddle, and paddle driving tube top passes Chi Tihou and is connected with drive motors.Water inlet and delivery port are all arranged along pond body sidewall tangential direction, and delivery port is positioned at below water inlet.
Further, the slope that described point constituency comprises vertical wall and extends to center along one end of vertical wall, the angle of inclination of slope and horizontal plane is 25 °-35 °.Paddle is near slope one end.
Further, described sediment outflow pipe bottom is provided with inhales sand mouth, and sediment outflow pipe top is provided with sand removing hole, and air inlet pipe is connected with air blast.
Further, be provided with reductor between described drive motors and paddle driving tube, drive motors and reductor fixed installation are on the cover board.
Further, described air inlet pipe bottom is formed a whole by support and sediment outflow pipe bottom.
Operation principle: sewage tangentially enters setting pot, under the paddle effect rotated, solid sand grains, by centrifugal force, gravity, buoyancy and fluid resistance acting in conjunction, starts sedimentation.In eddy flow process, granularity and the large sand grains of density are at the bottom of pool wall and pond, finally sink in the Ji Sha district at center, pond.Meanwhile, due to the moderate rotation of paddle, produce the speed slightly gone up mutually at the center of setting pot, make less, lighter object increase at pond central part, finally discharge with water outlet.The centrifugal force that paddle produces then pushes the heavier sand grains of sedimentation the sand collecting hopper of setting pot bottom.
By adopting preceding solution, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the difference in specific gravity between mixing wastewater with air liquid and water is relied on to be discharged by sand grains, the air purge of sand grains can be realized before air lift, can prevent the sand grains in sand collecting hopper from hardening, also the organic matter be attached on sand grains can be separated from sand grains simultaneously, thus the subsequent treatment facilitating sand grains to discharge.

Detailed description of the invention
Now with specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.
With reference to figure 1 the present embodiment, a kind of gas stripping type desander for rotational flow grit pit is disclosed, comprise pond body 1 and cover plate 11, pond body 1 comprises point constituency 2 being located at top, the Ji Sha district 3 being located at middle part and is located at the sand collecting hopper 4 of bottom, point constituency 2 sidewall offers water inlet 5 and delivery port 6; Pond body 1 central shaft is vertically arranged with hollow paddle driving tube 7, and paddle driving tube 7 inner chamber is provided with air inlet pipe 8 and sediment outflow pipe 9, and sediment outflow pipe 9 is positioned at paddle driving tube 7 lumen centers; Air inlet pipe 8 and sediment outflow pipe 9 one end are all near the bottom of sand collecting hopper 4, and air inlet pipe 8 and sediment outflow pipe 9 other end all pass pond body 1; Paddle driving tube 7 lower horizontal is axially provided with paddle 10, and paddle driving tube 7 top is connected with drive motors 16 after passing pond body 1.
Point slope 19 that constituency 2 comprises vertical wall 18 and extends to center along one end of vertical wall 18, slope 19 is 30 ° with the angle of inclination of horizontal plane; Sediment outflow pipe 9 bottom is provided with inhales sand mouth 13, and sediment outflow pipe 9 top is provided with sand removing hole 15, and air inlet pipe 8 is connected with air blast 14; Be provided with reductor 17 between drive motors 16 and paddle driving tube 7, drive motors 16 and reductor 17 are fixedly mounted on cover plate 11; Air inlet pipe 8 bottom is formed a whole by support 12 and sediment outflow pipe 9 bottom.
During work, sewage tangentially enters pond body 1 from water inlet 5, and under the paddle 10 rotated acts on, solid sand grains, by centrifugal force, gravity, buoyancy and fluid resistance acting in conjunction, starts to be settled down to sand collecting hopper 4; Air blast 14, by the sand grains air purge of air inlet pipe 8 pairs of sand collecting hopper 4 bottoms, produces mixing wastewater with air liquid and sucks sediment outflow pipe 9 through inhaling sand mouth 13, finally discharged by sand removing hole 15.
