Abstract
The utility model relates to a grit chamber which is matched with a collecting basin, which is arranged in front of the collecting basin, the upper half part of the grit chamber is of a cylindrical structure, the lower half part of the grit chamber is of a conical structure, the grit chamber is provided with a water inlet and a water outlet, a coarse bar screen is arranged in front of the water inlet, the bottom part of the grit chamber is provided with a diving shell pump, the diving shell pump discharges sediment mixture on the bottom part of the grit chamber into a sedimentation tank arranged additionally, so sediment entering the collecting basin of a sewage pump station (factory) can be reduced.
Description
Affiliated technical field
The utility model relates to a kind of sewage disposal setting pot, and particularly the situation that enters sewage pumping station (factory) in the dirty mixed flow pipe network water of city municipal administration rain is descended, the setting pot that is used with collecting-tank.
Background technology
At present, the dirty mixed flow water of the rain in most of city only passes through coarse rack one before entering sewage pumping station (factory) collecting-tank, promptly enters collecting-tank behind the following bigger floating thing of interception.In rainy season, road surface silt flows in the sewage network with rainwater, because the big flow velocity of the water yield is fast, many silts enter in sewage pumping station (factory) collecting-tank with water.Accumulate over a long period, silt deposition in sewage collecting basin is too much, and water collecting pool volume is reduced, and can not play cushioning effect, and is also too many because of silt, damages sewage pump.When serious, silt can bury standby sewage pump, causes to stop into water, often needs silt in the cleaning pond.
Summary of the invention
Before collecting-tank, can not remove the deficiency of silt in order to overcome prior art, the invention provides a kind of sewage disposal setting pot that is used with collecting-tank, can reduce the silt that enters in sewage pumping station (factory) collecting-tank.
The technical solution of the utility model is: a kind of sewage disposal setting pot, it is arranged on before the collecting-tank, the first half is a cylindrical structural, the latter half is a conical structure, this setting pot is provided with water inlet and delivery port, be provided with coarse rack before water inlet, be provided with the diving shell pump in this setting pot bottom, this diving shell pump enters the silt mixture of setting pot bottom in the sedimentation basin of other setting.
The invention has the beneficial effects as follows: the silt in the rain sewage at setting pot by the major part of avaling, can reduce silt and enter collecting-tank, reduce the wearing and tearing of sewage pump, guarantee effective water collecting pool volume, minimizing is too much cut off the water because of silt in the collecting-tank and is dug the number of times in pond, and reduces the quantity of sand and mud that brings to after-treatment system with sewage.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the use schematic diagram of the utility model setting pot;
Fig. 2 a, Fig. 2 b are the sectional views of the utility model setting pot.
1. setting pots, 2. diving shell pumps, 3. coarse racks, 4. sedimentation basins, 5. setting pot water inlets, 6. setting pot delivery ports among the figure
The specific embodiment
As shown in drawings, the dirty mixed flow water of silt rain that contains of coming in from the municipal wastewater pipe network enters setting pot (1) along setting pot (1) pool wall tangential direction by water inlet (5) through the coarse rack filtration, and setting pot (1) is the conical concrete structures of top cylindrical lower portion.In setting pot (1), particle silt sinks, and then, rain sewage flows out from setting pot delivery port (6), enters collecting-tank.Diving shell pump (2) is placed on setting pot (1) bottom, timing open.It draws up the silt mixture that comes and continue precipitation in the sedimentation basin (4) that is provided with in addition, and sediment is transported to the garbage disposal plant as rubbish.
Claims (1)
1. sewage disposal setting pot, it is arranged on before the collecting-tank, the first half is a cylindrical structural, the latter half is a conical structure, described setting pot is provided with water inlet and delivery port, be provided with coarse rack before water inlet, be provided with the diving shell pump in described setting pot bottom, described diving shell pump enters the silt mixture of setting pot bottom in the sedimentation basin of other setting.
