Description
Technical field
The utility model belongs to water-treatment technology field, relates to the device of silt in the municipal storm sewer of a kind of separation, especially a kind of storm sewer rotational flow grit chamber.
Background technology
The solid particulate matters such as silt that carry in a large number various pollutants enter water body with rainfall runoff through Municipal storm sewer, or lag deposit and discharge gradually pollutant in storm sewer, and water environment safety is constituted a serious threat.Sediment by rotational flow technology is cut down control method as a kind of efficient silt, and storm sewer abroad and confluence of rainwater and sewage pipeline silt are widely used in processing, and have developed multiple commercialization cyclone separator.At home, silt treatment facility is not generally set on storm sewer, urban rainfall runoff has directly enters river, the facility that dams of building on storm sewer having is processed part rainwater is delivered to sewage treatment plant, and the part rainwater that surpasses pipeline load or Sewage Plant disposal ability enters river.The patent of domestic existing urban discharging pipeline sediment by rotational flow technical elements is less, and ubiquity is a bit not enough, be exactly operational management inconvenience, existing drainage pipeline rotational flow sand sinking device or need impeller or paddle, be provided with the filter plants such as screen pack, the desilting of need to manually going into the well, and the solids complicated component that drainage pipeline current carry and amount are large, easily there is paddle by fibrous object winding, filter plant difficulty blocked, that manually go into the well in the operational managements such as desilting workload is heavy.
Summary of the invention
In order to overcome existing drainage pipeline rotational flow sand sinking device, have the deficiency of operational management inconvenience, the utility model provides a kind of storm sewer rotational flow grit chamber.
The utility model solves the technical scheme that its technical problem adopts: a kind of storm sewer rotational flow grit chamber, sand collecting hopper at the bottom of comprising setting pot, water inlet pipe, outlet pipe and being located at setting pot pond, it is characterized in that: setting pot inclined bottom surface, the top of setting pot is provided with the deflector of a reverse frustoconic, deflector central shaft overlaps with setting pot central shaft, and the upper edge of deflector is connected with setting pot roof; The trend of water inlet pipe and the sidewall of setting pot are tangent, and water inlet pipe cross section is square; Outlet pipe top is connected with the lower edge of deflector; Above sand collecting hopper, be provided with a newel in case falling stop enters the silt effusion of sand collecting hopper, it is conical that newel bottom is, and top is cylindrical, and newel is hollow; In sand collecting hopper, be provided with sand pump, sand pump is extracted into the silt in sand collecting hopper on ground by the interior tube connector of wearing newel.
The municipal rain pipe caliber that the cross section length of side of described water inlet pipe equals to be attached thereto.
The diameter of described setting pot equals 5 times of the water inlet pipe cross section length of side, and the gradient of setting pot bottom surface is 1:4.
The diameter of a circle that the upper edge of described deflector surrounds equals the diameter 3/5 of setting pot, and the diameter of a circle that the lower edge of deflector surrounds equals the diameter 2/5 of setting pot, and the gradient of deflector is 1:1.
The trend of described outlet pipe is by transferring straight up horizontal direction to, and outlet pipe end is pipe.
The beneficial effects of the utility model are: simple in structure, and in the situation that not being set, blade and filter plant keep higher desanding efficiency, and without the desilting of manually going into the well, operational management is convenient, and the reduction that is suitable for storm sewer silt is controlled.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Fig. 2 is the structural representation of facing of the present utility model.
In figure: 1-water inlet pipe, 2-deflector, 3-sand pump, 4-newel, 5-outlet pipe, 6-setting pot, 7-sand collecting hopper.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As depicted in figs. 1 and 2, a kind of storm sewer rotational flow grit chamber, the sand collecting hopper 7 at the bottom of comprising setting pot 6, water inlet pipe 1, outlet pipe 5 and being located at setting pot pond.Water inlet pipe 1 top is connected with the municipal storm sewer of upstream by ring flange, and the sidewall of the trend of water inlet pipe 1 and setting pot 6 is tangent, and water inlet pipe 1 cross section is square, the municipal rain pipe caliber that its length of side equals to be attached thereto.The diameter of setting pot 6 equals 5 times of the water inlet pipe 1 cross section length of side, setting pot 6 inclined bottom surfaces, and the gradient of its bottom surface is 1:4.At the top of setting pot 6, be provided with the deflector 2 of a reverse frustoconic, deflector 2 central shafts overlap with setting pot 6 central shafts, the upper edge of deflector 2 is connected with setting pot 6 roofs, the diameter of a circle that the upper edge of deflector 2 surrounds equals the diameter 3/5 of setting pot 6, the diameter of a circle that the lower edge of deflector 2 surrounds equals the diameter 2/5 of setting pot 6, and the gradient of deflector 1 is 1:1.Outlet pipe 5 tops are connected with the lower edge of deflector 2, and the trend of outlet pipe 5 is by transferring straight up horizontal direction to, and outlet pipe 5 ends are pipe, by ring flange, are connected with the municipal storm sewer in downstream.Above sand collecting hopper 7, be provided with a newel 4 in case falling stop enters the silt effusion of sand collecting hopper, it is conical that newel 4 bottoms are, top is cylindrical, newel 4 is hollow, newel 4 is fixed on setting pot 6 bottom surfaces by some support bars, between newel 4 lower edges and setting pot 6 bottom surfaces, leaves gap.In sand collecting hopper 7, be provided with sand pump 3, sand pump 3 is extracted into the silt in sand collecting hopper 7 on ground by the interior tube connector of wearing newel 4.
During work, in municipal storm sewer, from the water inlet pipe 1 of storm sewer rotational flow grit chamber, tangentially enter setting pot 6 containing sand current, current due to the constraint of setting pot 6 limit walls and deflector 2 at the interior swirling motion of doing of setting pot 6.Sand grain in water falls at the bottom of pond in the effect of gravity and current, then to central motion, falls into sand collecting hopper 7 along setting pot 6 bottom surfaces, restarts Sand pump 3 silt is extracted on ground so that post-processed when the silt of sand collecting hopper 7 is more.Flowing out from outlet pipe 5 compared with clean water stream of setting pot 6 tops.
