The utility model is mainly composed of a water ejector (1), a water pump (2), a water storage tank (3), a water circulating pipeline (4), a vacuum pumping water diversion connecting pipeline (5), an overflow pipeline (6), a sewage and drainage valve (7) and a gate valve (8), under the running action of the water pump (2), the water passes through the circulating pipeline (4), hydraulic power is ejected out, under the continuous circulating flow of the water ejector (1) and the water storage tank (3), the flowing water at high speed is ejected out through a spray nozzle inside the water ejector, negative pressure is formed at the throat of an injection pipe, vacuum is generated, the air of the empty vacuum pumping water diversion connecting pipeline (5) is pumped out to form the vacuum, sewage water is led on to a high position form a low position, the structure of the system is simple and applicable, the manufacturing and installation is easy, the running and management is convenient.
Description
Affiliated technical field
The utility model relates to a kind of sewage pump and sewage conduct vacuumizes diversion system.
Background technique
Urban sewage (domestic sewage, factory effluent, rainwater etc.), quantity is very huge, and it is very wide to distribute around our work, life and living environment, contains abundant low temperature heat energy, is the precious resources that can utilize again.
Using heat pump technical principle and relevant device thereof as low-temperature water source, in the winter time, can extract a large amount of low temperature heat energies that contain in the sewage to urban sewage, promote its temperature again, are the user heating heat supply.In summer, again can be urban sewage as cooling water source, the heat in the extraction chamber transfer of heat and carry away, is user's refrigeration air-conditioner by sewage.Need not build the boiler room winter, need not consume coal, oil, rock gas, utilizes the urban sewage just can heating.Summer, need not build cooling tower (water tower dries in the air), need not consume cooling water, utilize the urban sewage just can refrigeration air-conditioner.
At using heat pump technical principle and relevant device thereof, urban sewage is given fully again in the process system of utilization as low-temperature water source, urban sewage needs certain flow (quantity) and guarantees, what often can utilize all is sewage in the urban sewage pipe duct trunk line, its sewage quantity is bigger, and flow is also relatively stable.But urban sewage pipe duct trunk line is often buried underground all relatively dark, and below ground will have 5-6 rice or darker, if build underground sewage pump house, and complex structure, constructional difficulties is invested greatlyyer, and operation management is also inconvenient.More satisfactory is: sewage pump should be installed among the heat pump machine room on the ground, and Here it is requires us to solve the diversion problem that vacuumizes of sewage pump and suction port sewage conduct thereof.
The diversion that vacuumizes that vacuumizes diversion and clean waterpump and fresh water pipeline that sewage conduct is advanced in sewage pump and suction thereof is incomplete same, foreign material are more in the sewage, adopt vacuum pump and self-priming sewage pump, problems such as blocking pipe, valve, vacuum pump all take place easily, and operation and maintenance cleaning difficulty are bigger.
Summary of the invention
The technical scheme in the invention for solving the technical problem is: sewage pump and sewage conduct vacuumize diversion system and mainly include water pump, Vacuum Pumps, and the water storage tank three parts are formed.Under the pump operation effect, water constantly circulates between circulating line, Vacuum Pumps, water storage tank, within Vacuum Pumps, swiftly flowing water goes out through the nozzle high velocity jet, produce negative pressure in injection pipe throat, form vacuum, vacuumizing conduit pipe is connected with the peak of sewage pump and suction port sewage conduct thereof, just can extract the air in sewage pump and the suction port sewage conduct thereof out, form vacuum, urban sewage is drawn up from the pipe duct lower, for sewage pump starts the ready work of operation.
The beneficial effects of the utility model are: with simple in structure being suitable for of diversion system of water pump, Vacuum Pumps and water storage tank assembling, make and install easily, operation management is convenient.Compare with installing and using vacuum pump, operation and maintenance are all wanted simply, save the construction investment expense, of paramount importancely are: be difficult for stopping up equipment and pipeline valves such as vacuum pump.
Description of drawings
Below in conjunction with drawings and Examples to this practical further specifying.
Fig. 1 sewage pump and sewage conduct vacuumize diversion system structural principle and system flow chart.
Fig. 2 sewage pump and sewage conduct vacuumize diversion system embodiment general assembly drawing.
Among the figure 1, Vacuum Pumps, 2, water pump, 3, water storage tank, 4, water circulating pipe, 5, vacuumize conduit pipe, 6, overflow pipe, 7, blowdown and emptying valve, 8, gate valve.
Embodiment
Fig. 1 is that sewage pump and sewage conduct vacuumize diversion system structural principle and system flow chart.Vacuum Pumps (1) can the casting processing moulding, also can be with carrying out the machining moulding again after steel plate and the steel pipe welding.The selection of water pump (2) is to determine that by sewage conduct diameter that is evacuated and total length (i.e. the amount of vacuumizing) can select DN50-100mm generally speaking, flow is a 50-100 rice
3/ hour, pressure is the vertical or horizontal centrifugal pump of 0.2-0.5Mpa, and these parameters of water pump are not absolute, and size can change, and is very not big to the influential effect that vacuumizes.Water storage tank (3) can be used steel plate, steel pipe weldering system, can be various ways such as cylindrical, square, rectangular, and volume is changeable.
1, Fig. 2 is that sewage pump and sewage conduct vacuumize the diversion system general assembly drawing, water-jet (1) should be vertically mounted on water storage tank (3) directly over.
2, the injection pipe of Vacuum Pumps (1) outlet will maintain necessarily required distance apart from the bottom of water storage tank (3), at least more than 800-1000mm, otherwise can influence the effect that vacuumizes of Vacuum Pumps (1).
3, blowdown and drain valve (7) should be installed in the bottom of water storage tank (3).The suction port of water pump (2) should be connected in the Lower Half of water storage tank (3), and spill pipe (6) should be connected the first half of water storage tank (3), should make water storage tank (3) in the continuous operation process of water pump (2), can store the water of certain volume all the time.
Native system can overall package become a kind of transportable system, also can be fixedly mounted near sewage pump and the sewage conduct, becomes a kind of fixed system.
4, under the running effect of water pump (2), water is through circulating line (4), Vacuum Pumps (1), water storage tank (3) constantly circulates, within Vacuum Pumps (1), swiftly flowing water comes out through nozzle ejection, produce negative pressure in sparger throat, form vacuum, the air that vacuumizes in the conduit pipe (5) is extracted out, also form negative pressure, vacuumize conduit pipe (5) and be connected, can all extract the air of sewage pump and suction sewage conduct thereof out emptying with the peak of sewage pump and suction sewage conduct thereof, urban sewage is guided on the ground by the pipe duct lower, for adequate preparation work is carried out in the startup operation of sewage pump.
