Description

A kind of Vatch basin with debris retaining function
Technical field
The utility model relates to a kind of Vatch basins with debris retaining function, belong to Municipal pumping equipment technical field.
Background technique
Vatch basin is the important structures in one of municipal drainage system, collects dry days in line sewage, and the abatement rainy day overflows Stream pollution.When dry days, the sewage of discharge outlet along the river is shut off into sewage treatment plant;When the rainy day, part rain dirt mixed flow water is cut Stream enters sewage treatment plant, and the rain dirt mixed flow water more than the ability of shutting off is discharged into surface water body.
Traditional Vatch basin has slot type, the weir weir Shi Hecao convolution, has the following problems: 1, designing combined closure system and objective need The combined closure system asked enters and leaves very big.Design combined closure system is that it is high to set different overflow weirs by centainly investigating and theoretical calculation The measures such as degree determine;The combined closure system of objective demand is dirty according to the actual conditions of each row mouthful interflow mixed flow and overflow What the ability of dye control requirement and urban sewage treatment system determined.The error of the two is very big, and height of weir plate is once setting It is difficult to adjust.2, water drainage blocks water.Design discipline requires overflow weir to rise higher than river flood position to prevent river water from flowing backward, this is bound to It is unsmooth to form water drainage.3, shut off low efficiency.It has usually been connected several Vatch basins by the main pipe that shuts off in drainage system, upper one A well shut off after water shut off with next well before water mix after shut off again, mixed flow water is diluted step by step, eventually enters into sewage The water concentration of system is low.4, it deposits seriously polluted.What is shut off is mostly surface layer water body, and pipe, well deposition are seriously polluted, finally with heavy rain It washes away one and is incorporated to river, influence Urban Water Environment.
In recent years, Vatch basin technology has obtained certain development, and the gate valve of main reliable power manipulation substitutes fixed weir, Realize that combined closure system is adjustable;There is the automated system according to the information such as rainfall, river water level control gate valve aperture;Reliable buoyancy Complicated transmission device of control gate valve aperture, etc..These new technologies realize the controllable of combined closure system, but actually adjustment is shut off Amount problem only needs to can be solved by 1~2 manual adjustment, using complicated electromechanical equipment and automatic control equipment, necessity Not strong, high failure rate, investment is big, O&M cost is high.In addition, the situations such as the water concentration that shuts off is low, water drainage blocks water still have.
Summary of the invention
The utility model is for combined closure system of the existing technology is difficult to control, the water concentration that shuts off is low, water drainage blocks water, river water Flow backward, complex structure and other problems, provide a kind of production method of no efficient Vatch basin of equipment controlled amounts underflow type, improves and cut dirt Efficiency is adapted to water of shutting off, and fair current is freely arranged, and reflux check, no mechanical equipment, high reliablity is with low investment, and O&M cost is low, fits Close Chinese city Status Quo of Infrastructures and demand for development.
In order to achieve the above-mentioned object of the invention, the technical solution adopted in the utility model provides a kind of shutting off for tool debris retaining function Well, it includes double storehouses well body, mixed flow tube, pipeline leakage plugging device, debris retaining grid and flap valve;Its structure are as follows: double storehouse well bodies are classified as by partition wall Shut off storehouse and debris retaining storehouse, mixed flow tube passes through storehouse two sides of shutting off, and is connected to debris retaining storehouse;In storehouse of shutting off, the middle section bottom of mixed flow tube Be provided with notch, enter the outlet of main pipe of shutting off for mixed flow sewage, pipeline leakage plugging device is socketed on mixed flow tube, the internal diameter of the pipeline leakage plugging device with Mixed flow pipe outside diameter is identical, and length is greater than mixed flow tube undercut;Pipeline leakage plugging device is moved axially, the opposite position of pipeline leakage plugging device and notch is changed It sets, for adjusting the flow of mixed flow outlet of sewer;Debris retaining grid are mounted in debris retaining storehouse, and the height of discharge outlet is lower than debris retaining grid, are set In the side in debris retaining storehouse, the outlet end of discharge outlet is inclined-plane, and flap valve is mounted on the outlet end of discharge outlet.
In technical solutions of the utility model, the shut off bottom in storehouse of the well is equipped with chute, and the shaped upper part of chute is both sides Low arc between senior middle school, the main pipe that shuts off are set among chute.
Compared with prior art, the utility model has the beneficial effects that:
1. controllable combined closure system.Relative position by adjusting pipeline leakage plugging device can adjust the size of practical combined closure system, effectively repair Positive design error, makes it more meet objective requirement, utmostly controls overflow under conditions of municipal sewage treatment ability is certain Pollution.2. eliminating because of the resistance that drains flooded fields caused by shutting off.3. underflow type mixed flow tube lower cut can reach higher concentration of shutting off.4. It solves the problems, such as to dilute step by step.5. meaning higher reliability, the more investment that saves and less without equipment design O&M cost.6. the design of debris retaining storehouse is effectively intercepted as storm runoff enters the slag sundries of well body, water environment is protected.7. entering river row Putting mouthful elevation can arbitrarily set as needed, not limited by mixed flow tube elevation.8. flap valve design can be realized draining it is unobstructed, and Prevent river water from flowing backward;9. maintenance is convenient and low in cost in later period cleaning and well.
