Abstract
The utility model discloses a unpowered anti-backflow forced-ventilated cuts dirty system, its characterized in that: including the bilge well, the bilge well through set up on the lateral wall cut dirty outlet and flood discharge outlet respectively with cut dirty well and flood discharge well intercommunication, and the flood discharge outlet sets up in the top of cutting dirty outlet, cut dirty well and pass through immersible pump and sewage treatment pipe network intercommunication. The system realizes the unpowered system functions of sewage interception, flood discharge and backflow prevention, has compact form, low cost, convenient use, durability and no need of frequent maintenance, avoids the electromechanical accident risk of the common sewage interception and backflow prevention system, and generates good economic and environmental benefits, such as electricity charge, system software update charge, manual maintenance charge, accident measure charge and the like.
Description
Technical Field
The utility model belongs to the technical field of sewage treatment, concretely relates to unpowered anti-backflow forced drainage cuts dirty system.
Background
In the current domestic urban sewage pipe network combined system drainage system, the intercepting technology of China engineering construction standard CECS91:97 < Combined System Sewage intercepting well design Specification > is generally adopted for intercepting drought sewage and initial rainwater to a sewage pipeline, in the intercepting system, an intercepting well not only ensures that the intercepted sewage enters a sewage intercepting system to achieve the purpose of conditioning the environment, but also ensures that rainwater with flow exceeding the street flow cannot enter the sewage intercepting system during heavy rain, thereby causing the condition that a sewage treatment plant is difficult to operate.
In the anti-backflow sewage intercepting system used at present, sewage interception and anti-backflow are wholly or partially performed with electric power anti-backflow, equipment needs to be replaced periodically, overall investment is high, equipment cannot be started when running faults exist in engineering practice, engineering risk accidents exist, cost is high, and therefore targeted improvement design is needed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a unpowered prevents flowing backward forced drainage and cuts dirty system and come into use to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an unpowered prevents flowing backward and forces row and intercept dirty system, includes the bilge well, the bilge well through the sewage interception outlet and the flood discharge outlet of seting up on the lateral wall respectively with sewage interception well and flood discharge well intercommunication, and the flood discharge outlet sets up in the top of intercepting the sewage discharge outlet, sewage interception well passes through immersible pump and sewage treatment pipe network intercommunication.
Preferably, a duck bill valve is arranged at the outlet of the flood discharge port.
Preferably, the inner side of the sewage interception and drainage port is detachably provided with a grid.
The utility model discloses a technological effect and advantage: this unpowered anti-backflow forced drainage cuts dirty system, set up respectively through the low eminence at the bilge well and cut dirty outlet and flood discharge outlet and communicate with vatch basin and flood discharge well respectively, cooperate the duckbill valve simultaneously, realized cutting dirty, the unpowered system function that floods and prevent flowing backward, the form is compact, and is with low costs, high durability, need not frequent maintenance, and avoided cutting dirty often and prevent the electrical machinery accident risk that flows backward the system existence, produce fine economy and environmental benefit, for example, the charges of electricity, system software updates the expense, artifical maintenance expense, accident measure expense etc., and through setting up, open and stop according to cutting the concrete water level control immersible pump in the bilge well, realize high-efficient quick drainage, avoid simultaneously avoiding when sewage treatment plant is in the sewage treatment upper limit to continue to carry rain sewage mixing water, therefore, the clothes hanger is strong in practicability.
Drawings
Fig. 1 is a top view of the present invention;
fig. 2 is a schematic structural diagram of the present invention.
In the figure: 1. a bilge well; 2. a flood discharge outlet; 3. a sewage interception and drainage port; 4. a catch basin; 5. flood-well running; 6. a duckbill valve; 7. a submersible pump; 8. a grid mesh.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a flowing backward forced drainage cuts dirty system under unpowered as shown in fig. 1-2, including bilge well 1, bilge well 1 through the sewage interception outlet 3 and the flood discharge outlet 2 of seting up on the lateral wall respectively with cut dirty well and flood discharge well 5 intercommunication, and flood discharge outlet 2 sets up in the top of intercepting sewage outlet 3, the sewage interception well passes through immersible pump 7 and sewage treatment pipe network intercommunication.
And a duck bill valve 6 is arranged at the outlet of the flood discharge outlet 2.
In dry seasons, when the water inflow of the sewage well 1 is small, the water level in the sewage well 1 is low, at the moment, sewage is discharged into the sewage intercepting well through the sewage intercepting and draining port 3 at the lower position, and the sewage is conveyed to a sewage treatment pipe network of a treatment plant through the submersible pump 7 for sewage treatment;
in rainy season, when the water inflow of the sewage well 1 is large, the water level in the sewage well 1 is rapidly increased, the sewage level overflows the flood discharge outlet 2, the sewage is conveyed to the duckbill valve 6, the duckbill valve 6 is extruded by water pressure to open and discharge water outwards to discharge the flood, and after the water level in the sewage well 1 is lower than the flood discharge outlet 2, the duckbill valve 6 is closed, river water is prevented from flowing backwards to the sewage well 1 by arranging the duckbill valve 6, the submersible pump 7 in the sewage well 1 stops working at the moment, so that a large amount of rainwater is prevented from entering a sewage pipe network of a treatment plant to impact the sewage treatment plant, the whole system realizes the unpowered system functions of sewage interception, flood discharge and backflow prevention, has compact form and low cost, is convenient to use, durable and free from frequent maintenance, avoids the electromechanical accident risk of a common sewage interception and backflow prevention system, and generates good economic and environmental benefits, such as electricity charges, system software update charges, manual maintenance charges, accident measures charges, and the like.
The inner side of the sewage interception and drainage port 3 is detachably provided with a grid 8. The sundries in the sewage are filtered, and a large amount of sundries are prevented from entering the sewage treatment pipe network.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
