Abstract
The invention belongs to an innovative design for balancing an automatic water distribution system. The system structure comprises a floating plate, a fixed pulley, a rope, a plumb bob, an airbag and a siphon; the sewage flows into the system from a water inlet, and then flows out the system from a water outlet after passing through the siphon; an automatic closing valve is arranged at the water inlet; when the water volume in a water inlet pool is evacuated, the closing valve is automatically closed since the suffered floating force is declined, thereby controlling the liquid in the siphon to flow out; when a water level in the pool is risen, the valve floats upward and is automatically opened to form the siphonage, thereby enabling the water flow to flow out in balance. The automatic water distribution system is an environment-friendly equipment system without energy consumption, and can be extensively applied to constructed wetlands, oxidation ponds, land sheetflood and other sewage ecological purification engineering.
Description
Technical field:
The invention belongs to a kind of innovative design of balanced automatic distributing system, is to be combined to float with fixed pulley using siphon principle
The principle design of power is formed, and water distribution can be made to keep the state of an equalization stable, and the environmental protection equipment system of Non-energy-consumption, can
Among being widely used in the sewage ecological purification engineerings such as artificial swamp, oxidation pond, soil cross flow.
Background technology:
In today that water pollution and shortage of water resources problem are increasingly serious, Ecological Disposal has wide development space.
The Artificial Wetland Techniques of undercurrent, vertical current and surface stream, the work such as oxidation pond and soil cross flow can be divided into according to water body fluidised form
Journey technology, has huge using value in Midwest villages and small towns, excellent with low, the simple, high treating effect of management of processing cost etc.
Point.
But, with the progressively expansion of ecological engineered range of application, the problem for clean-up effect difference occur becomes increasingly conspicuous, raw
State engineering utilization rate declines year by year, and a series of problems, such as thus cause the Engineering Service time limit to shorten.In the case, research is sent out
The design of existing Traditional Ecological technology remains in the empirical construction phase, lacks effective method for designing, sewage discharge rate
Treatment facility is directly entered without control, the generally generation of inflow non-uniform phenomenon causes treatment effect unstable, is destroyed
Ecological treatment system.For the problems referred to above, the present invention is designed using the principle that siphon principle is combined buoyancy with fixed pulley, is made
Sewage keeps the state stream of an equalization stable to enter treatment facility, and low energy consumption, and low cost meets the equipment requirement of environmental protection
Standard.
The content of the invention:
The present invention is a kind of constant current mode water distribution system, and by three fixed pulleys, a kickboard and an elevation plummet group is regulated and controled
Into control system, the depth displacement for controlling siphon pipe two-stage water oral fluid face and delivery port is invariable, reaches water distribution quantity balanced
Stable purpose, realizes and automatically adjusts discharge function, solves sewage quantity and flows directly into without control, causes pollutant to be born
The problems such as lotus is uneven.
The method for designing of balanced water distribution system be for the purpose of water distribution equalization stable, design basis be siphon principle and
Fixed pulley both sides equilibrium principle, control pipeline imports and exports two sections of depth displacements, realizes that its fundamental formular is as follows：
M1g-ΔFIt is floating=M2g-ΔMg (2)
In formula (1)：ρ is sewage density (kg/m3), g is gravitational constant 9.8, and △ h are depth displacement (m), and V is water speed in pipe
(m/s)；
In formula (2)：M1For kickboard quality (kg), △ FIt is floatingBuoyancy (N), M suffered by kickboard2For plumb mass (kg), △ M are
The quality (kg) of water side pipe and internal water.
System constructing is concretely comprised the following steps：
(1) a balanced automatic distributing system is set up：
Balanced automatic distributing system structure includes kickboard, fixed pulley, rope, plummet, air bag and siphon pipe, and sewage is by intaking
Mouth is flowed into, Jing after siphon pipe, by delivery port outflow system.Water inlet arranges automatic closing valve door, when the emptying of the intake pool water yield, closes
Close buoyancy suffered by valve to decline, automatically closure, liquid flows out in control siphon pipe, and liquid level rises in pond, valve floats and automatically opens up,
Siphonage is formed, goes out current equilibrium.
(2) design of liquid level and delivery port depth displacement：
The pressure that the principle of automatic equalization water distribution system is mainly produced by the difference of turnover liquid level adjusts sewage steady flow
Go out, geographical position is certain, and acceleration of gravity is constant, and the size of pipe and the selection of depth displacement decide flow, due to siphon pipe
Maximum allowable vacuum values are 7.5 meters, so liquid level is less than 7.5 meters with the vertical height of siphon pipe peak.According further to water inlet
Amount size, chooses the pipe of suitable thickness.
(3) selection of plummet and kickboard weight：
Quality from formula (2), plummet and kickboard is certain, and it is change that kickboard is subject to the gravity of buoyancy and outlet pipe
With liquid surface lifting, but kickboard quality is greater than 1-2 times of plummet, and the weight of plummet is 1-2 times of gross weight when outlet pipe is full of water,
Can so ensure that liquid surface lifting directly adjusts the variation of delivery port.
The present invention is a kind of innovative design of constant water inlet device, is designed using machinery and siphon principle, operation letter
It is single, it is practical, ensure that the water inlet of sewage treatment facility equalization stable.
Description of the drawings：
Accompanying drawing 1 is the schematic diagram of present invention equilibrium automatic distributing system.
Specific embodiment:
Embodiments of the invention：
(1) to embody effectiveness of the invention, a physical model is set up, as shown in Figure 1, pond body is PVC board,
Design of length is 1.2 meters, and width is 0.6 meter, and depth is 0.8 meter, uses batten fixed block, and tightrope is by kickboard (12kg) and plummet
(6kg) link, two link on plummet and outlet pipe, and water inlet pipe side is fixed, and water inlet is seated in bottom of pond.Then adjusting rope
Son, the depth displacement for being into and out mouth is certain, and injected clear water keeps pulley block balance, using gas in air bag evacuated tube, forms rainbow
Inhale.Simultaneously different size of caliber is chosen, the difference of proof theory flow and monitor value is carried out in the case of different elevation differences
It is different.Experimental result is as shown in table 1.
As shown in Table 1, balanced automatic distributing system has stable water distribution under conditions of different calibers and depth displacement
Effect, under the conditions of identical caliber, with the increase of depth displacement, error amount diminishes, five kinds of calibers when depth displacement is less, error
Value is larger, less due to depth displacement, and liquid level has certain rear stickiness, so as to expand error, the experiment with the variation of delivery port
The accuracy and stability of main checking water distribution system, depth displacement is much larger than 0.06 meter in practical application, so, this example is proved
Balanced automatic distribution water has actual application value.
The comparison of flow monitoring value and theoretical value under the conditions of the different tube diameters of table 1 and depth displacement
The above, is only to implement example to the design, and any pro forma restriction is not made to the design method,
Any simple change and modification that every technical spirit according to the design is made to above example, still belong to the Technology design side
The protection domain of case.
