The utility model relates to a device used for eliminating the sewerage or the storm water. The utility model mainly solves the problem of the diffluence automatic switchover of the clear water and sewerage (the rain water of precontamination) and efficaciously overcomes the defect of the manual control. The switching device main body 1 which is composed of a sewage chamber AAn a clean water B and a desilting chamber C is provided with an intake pipe 2, a drainage pipe 3 and a blowdown pipe 4. The utility model is characterized in that the sewage chamber A is provided with an energy dissipation box 5, an automatic switching valve 6 and an ejector 7, the utility model mainly takes advantage of the difference of the (drainage) system flow rate for making the change of the water level (potential energy), the change of the flow velocity (kinetic energy) of the stream current for controlling the open and close of the automatic switching valve and the diffluence fluidic system for controlling the length of the shooting flow, and the difference of the (drainage) system flow rate, the change of the flow velocity (kinetic energy) of the stream current and the diffluence fluidic system are matched with each other for carrying out the diffluence switchover.

Description

Automatic switching device for clear and dirty water flow

The utility model relates to the device of draining-off sewage or stormwater.

Existing clear, sewage separation switching device shifter mostly is masonry structure, and particularly the control to current be Artificial Control all, as utilizes slide valve, open and close time-consuming, require great effort, be difficult to reach the switching purpose.

The purpose of this utility model is to overcome clearly, the manually operated shortcoming of sewage separation switching device shifter, and switching device shifter is structurally improved, and designs a kind of clear, sewage (early-stage rainwater) shunting and realizes the device that automaticallyes switch.

The purpose of this utility model is achieved in that clearly, the sewage separation automatic switching control equipment, form the switching device shifter main body by sewage chamber, clean water chamber and desilting chamber, be provided with water inlet pipe, gutter and blow-off pipe, it is characterized in that being provided with in the sewage chamber baffle box, automatic transfer valve and ejector.

Below the utility model is described further by drawings and Examples:

Fig. 1 is the utility model plan structure schematic diagram.

Fig. 2 is an automatic transfer valve master TV structure schematic diagram.

Fig. 3 is an ejector plan structure schematic diagram.

Fig. 4 is I-I sectional view of Fig. 1.

Fig. 5 is II-II sectional view of Fig. 1.

Fig. 6 is III-III sectional view of Fig. 1.

Mark among the figure: 1. switching device shifter main body, 2. water inlet pipe, 3. gutter, 4. blow-off pipe, 5. baffle box, 6. automatic transfer valve, 7. ejector, 8. stop, 9. flashboard, 10. tension equipment, 11. spilled water holes, 12. nozzle, 13. collect short tube, A. sewage chamber, B. clean water chamber, C. desilting chamber.

As shown in drawings: clear, sewage separation automatic switching control equipment, reach the desilting chamber C that leads to sewage chamber A structure by sewage chamber 4, clean water chamber B and form switching device shifter main body 1, be provided with water inlet pipe 2, gutter 3 and blow-off pipe 4, it is characterized in that being provided with among the sewage chamber A baffle box 5, automatic transfer valve 6 and ejector 7.As shown in the figure: automatic transfer valve 6 is made up of the spilled water hole 11 on stop 8, flashboard 9, tension equipment 10 and the flashboard 9, and is positioned at before the blow-off pipe 4.Ejector 7 is positioned at water inlet pipe 2 rear ends and is made up of nozzle 12 and collection short tube 13.The caliber that enters the water inlet pipe 2 of sewage chamber A, the gutter 3 that goes out clean water chamber B and nozzle 12 is Φ 1; The caliber that goes out the blow-off pipe 4 of sewage chamber A is Φ 2; The caliber of collecting short tube 13 is Φ 3, one end flare, and it is conical that an end of the nozzle 12 that is complementary with it then is.Switching device shifter main body top plan view can optionally be made square type, round or square etc.; Its material can adopt steel concrete, masonry, glass fiber reinforced plastic or carbon steel structure etc.

Working condition of the present utility model is such: beginning, the sewage chamber A of the water inlet of low discharge (contaminant water) from water inlet pipe 2 inflow devices is full of baffle box 5 earlier and by automatic transfer valve 6, delivers to the sewage-farm through blow-off pipe 4.When flow of inlet water increases, when water quality improved gradually, sewage chamber A middle water level rose, and the water level that the flashboard 9 of automatic transfer valve 6 is risen slowly compresses and turns down blow-off pipe 4 gradually; Water level continues to rise, and continues compression flashboard 9, until closing blow-off pipe 4 fully.Meanwhile, because the increase of inflow, flow rate of water flow also strengthens, and causes the ejector 7 performance jet actions of water inlet pipe 2 front ends, and nozzle 12 ejection water jets are ejected among the clean water chamber B through collecting short tube 13, are drained in the clean water pipe network system by gutter 3 and go.When water inlet pipe 2 stops into water, the spilled water hole 11 of water on flashboard 9 that remains among the sewage chamber A flows out, the drawdown of sewage chamber A, when water level drops to self hydrostatic pressing less than the pulling force of the tension equipment 10 of automatic transfer valve 6, flashboard 9 is tightened up equipment 10 and draws back, so it is blow-off pipe 4 is opened, in running order again.When beginning to intake, the precipitum that may bring in the sewage except that being got rid of by blow-off pipe 4, is concentrated in the bucket among the C of desilting chamber, can remove on time.This shows, the utility model mainly is to utilize (draining) flow system flow difference to cause the variation of water level (potential energy) and utilize the hasten keying of variation control automatic transfer valve 6 of (kinetic energy) of current, and the keying degree of flashboard 9 and opportunity are then regulated by stop 8 and tension equipment 10; The length of the automatic shunting of utilization fluidic system control jet and automatic transfer valve 6 cooperatively interact and shunt switching in addition; And the water conservancy by system engineering is calculated and is reached the control shunting, switches requirements such as the water flow and the time interval.

Problem clear, that sewage (precontamination rainwater) shunting is automaticallyed switch that the utility model has effectively solved.Device construction is simple, and easy construction can be made at engineering site, but also the batch production seriation is produced in batches.Help appropriate design, can reduce the engineering construction scale, save capital investment; Clearly, sewage (precontamination rainwater) shunting automatic switchover accuracy height, management is simplified, and is stable, can reduce the sewage-farm treating capacity, saves operating cost.

The utility model is mainly used in work areas such as tank farm, oil jetty, the occasion that also can be used for other need be clearly, sewage separation automaticallyes switch.Has tangible technical economic benefit.
