5 Opening pressure.When normal dosing, first manual adjusts pressure valve 5 and opens, and second adjusts pressure valve 8 manually closes, once it is main
When the pressure of pipeline has been more than setting value, second adjusts pressure valve 8 manually opens, and is discharged to extra lysate.The knot
Main problem existing for structure is：Single pipe-line system, efficacy of drug administration is low, once pipeline breaks down or cleaning aluminium salt dissolving tank
When, system is out of service；Extra lysate discharge causes to waste and pollutes environment.In addition, not due to Fluid pressure and flow
Stabilization causes pipe vibration larger, and there are the risks of downstream instrument and equipment damage；Pressure gauge only display system pressure, flowmeter
7 outlet pressures can not be observed to obtain.
Utility model content
The utility model aims to solve the problem that low existing efficient aluminium salt medicine system efficiency, pipeline repair or cleaning aluminium salt dissolving
The problem of needing system-down and extra lysate to discharge waste and pollution environment when pond.
For this purpose, technical solution used by the utility model is：A kind of efficient aluminium salt medicine system, including by least two
The dissolving tank group that aluminium salt dissolving tank is constituted, and the dosing pipe group that is made of at least two dosing pipes in parallel, it is described molten
After Xie Chi groups are connected with dosing pipe group, it is separated into two dosing branches and is respectively connected to secondary settling tank chemical feeding points and flocculation basin dosing
Point；Two aluminium salt dissolving tanks share same tap water access pipeline, and on the water inlet pipe of each aluminium salt dissolving tank there are one outfits
Shut-off valve, is equipped with that there are one shut-off valves on outlet pipe；The dosing pipe includes the shut-off valve, filter, metering being sequentially connected in series
Pump, first manual adjust pressure valve, pressure gauge, flowmeter, shut-off valve, and it is indirectly to adjust pressure valve in metering pump and first manual
There are overflow branch, the end of overflow branch to be connected between filter and metering pump, overflow branch road is equipped with second and adjusts manually
Pressure valve, the second Opening pressure for adjusting pressure valve manually are more than the Opening pressure that first manual adjusts pressure valve；Add at every
Medicine branch road is provided with shut-off valve.
The metering pump and first manual are adjusted as a preferred embodiment of the above solution, is also in series on the pipeline between pressure valve
Pulsation damper terminates at first manual before the overflow branch and adjusts between pressure valve and pulsation damper.In main line
On add pulsation damper, pulsation damper is a kind of for eliminating liquid pressure pulsations or the pressure of flow pulsation in pipeline
Container can play stabilized fluid pressure and flow, eliminate pipe vibration, protection downstream instrument and equipment, increase pump volumetric efficiency
The effects that；
In addition to the pressure gauge display system pressure on main line, pulsation damper carries pressure display table, for showing stream
The pressure of gauge outlet end.
Further, the filter uses y type filters, metering pump to use the Hydraulic Diaphragm Metering Pump of bottom in and top out.Y types
Filter good filtration effect, price are low；Hydraulic Diaphragm Metering Pump can select different materials according to the difference of measured medium, fit
Wide with range, built-in overvoltage safety protection valve eliminates the trouble of general metering pump installation bypass, not only saves space, but also increase
The safety that product uses is added.
The utility model has the beneficial effects that：
(1) dissolving tank group is constituted by least two aluminium salt dissolving tanks, dosing pipe group is constituted by least two dosing pipes,
When a certain dosing pipe breaks down or clears up a certain aluminium salt dissolving tank, dosing pipe in addition and the normal work of aluminium salt dissolving tank
Make, avoids causing system-down；Also, after dissolving tank group is connected with dosing pipe group, it is separated into two dosing branches and connects respectively
To secondary settling tank chemical feeding points and flocculation basin chemical feeding points, pipeline arrangement is optimized, cost has been saved；
(2) end of overflow branch takes back on main line, the environmental pollution for avoiding lysate from wasting and bring.
