Abstract
The utility model discloses an initial stage rainwater is abandoned to flow through and is strained automatic control device, including the well body, the internal filter screen that sets up of well is divided into into water side and play water side with well body inner space, the side upper segment of intaking of the well body is provided with the inlet tube, goes out water side upper segment and is provided with the outlet pipe, a well body water side is provided with abandons class pump and sewage connecting pipe intercommunication, the internal float switch of controlling out the water side by the controller that still is provided with of well. The utility model has the advantages of reasonable in design, simple to operate, easy operation, to abandon class effect better, can alleviate the loaded down with trivial details degree of manual operation greatly, have higher practical meaning.
Description
Technical field
The utility model relates to a kind of early-stage rainwater stream abandoning filter, particularly relates to a kind of early-stage rainwater stream abandoning and filters automaton.
Background technology
Rain water drainage filter is adopted to process rainwater, it is the effective storm water management method of one that industry is commonly used in rainwater catchment system process, according to mensuration, rainwater-collecting process moderate rain water pollution degree the highest be the rainwater of Rainwater Initial 2-5mm, the pollutant of more than 70% results from this period.In Rainwater collection system, the quality of rain water drainage, is directly connected to the effect of a rainwater-collecting.If it is bad that rain early-stage split-flow does, allow impurity flow into catch-basin or collecting pit, after long-time, Impurity deposition, at the bottom of pond, brings very large trouble will to the cleaning work in later stage, even cause whole system to be paralysed.Therefore, carry out rainwater catchment system, the abandoned stream of Rainwater Initial is most important.Pollutant higher for Rainwater Initial concentration can effectively be abandoned by rainwater flow-discarding device, realizes, at rainwater-collecting precontamination thing automatic-discharging, being convenient to filtration and the collection of rainwater-collecting later stage clean rainwater.At present, engineering being used more is flow abandoning apparatus by gravity or volumetric void fraction, when catchment area is larger, there will be abandoned stream not thorough, and have a lot of drawback for by the drainage problem of the early-stage rainwater of abandoned stream, as draining needs manual operation, or absolute altitude reason cannot flow to soil pipe etc. certainly, waste time and energy, effect is unsatisfactory.
Utility model content
Technical problem to be solved in the utility model is, overcomes the above defect, provide a kind of simple to operate, automatic control level is higher, easy to maintenance, the rain early-stage split-flow of good practical effect filter automaton.
In order to solve the above technical problem, early-stage rainwater stream abandoning described in the utility model filters automaton, comprise well body, filter screen is set in described well body well body inner space is divided into influent side and water outlet side, the influent side epimere of described well body is provided with water inlet pipe, water outlet side epimere is provided with outlet pipe, described well body water outlet side is provided with abandoned stream pump and is communicated with sewage tube connector, is also provided with the float switch being controlled water outlet side by controller in described well body.
As preferably, filter screen described in the utility model is arranged on the middle part of described well body.
When early-stage rainwater flows through this device, first by filter screen, larger sundries blocking is entered well body water outlet side after well body water inlet side, after water level rises, water level float switch sends digital quantity signal to controller, give abandoned stream pump and open the signal of telecommunication, early-stage rainwater is drained into soil pipe, does not limit by absolute altitude.The utility model can calculate according to catchment area the perdurabgility that maximum abandoned stream amount arranges water pump unlatching, and after reaching setting-up time, water pump cuts out, and later stage clean rainwater then flows to delivery port and flows out through outlet pipe.
The utility model, abandoned stream amount can be set voluntarily according to actual service condition, and early-stage rainwater draining is force pipe (namely relying on pressure as power carrier pipe inner fluid), not by restrictions such as absolute altitude distances, disposablely solve abandoned stream in prior art thoroughly and the problem brought by abandoned stream early-stage rainwater impeded drainage, alleviate operator's work fussy degree.
The beneficial effects of the utility model: the utility model has the advantages such as reasonable in design, easy for installation, simple to operate, abandoned stream effect is better, greatly can alleviate manual operation fussy degree, have higher Practical significance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Early-stage rainwater stream abandoning described in the utility model filters automaton, comprise well body 1, filter screen 2 is set in described well body 1 well body inner space is divided into influent side and water outlet side, the water-in and water-out side of described well body 1 arranges water inlet pipe 3 and outlet pipe 4 respectively, described well body 1 water outlet side is provided with abandoned stream pump 5 and is communicated with sewage tube connector 6, is also provided with the float switch 7 being controlled water outlet side by controller 8 in described well body 1.
As preferably, filter screen 2 described in the utility model is arranged on the middle part of described well body 1.
Embodiment: when early-stage rainwater enters (the b water level as in Fig. 1) when well body 1 reaches designated water level, the control of the controlled device 8 of float switch 7 makes water pump and abandoned stream pump 5 open, early-stage rainwater is drained into municipal wastewater pipe network through tube connector 6, when water level decreasing is to (a water level as in Fig. 1) during low water stage, float switch 7 controls water pump and cuts out, stop effluent discharge, so repeatedly, early-stage rainwater high for degree of contamination is discharged; When starting mode of pump total time reaches setting value, water pump is no longer opened, and later stage cleaner rainwater is discharged by outlet pipe 4.Filter screen 2 described in the utility model is arranged on centre, and by well body inner space dimidiation, some larger foreign material are isolated in influent side, so both protect the normal work of water outlet side abandoned stream pump 5, plays again the effect of filtering rainwater.In order to ensure that early-stage rainwater stream abandoning described in the utility model filters automaton and normally uses for a long time, need necessarily to safeguard, under normal circumstances, half a year in dry season draws clearly once, and three months rainy seasons drew clearly once.
Claims (2)
