Description
Technical field
The utility model belongs to technical field of sewage, and in particular to a kind of dosing transport system.
Background technology
It inevitably needs that flocculent solving liquid, white lime lysate etc. is added in sewage disposal process, is referred to as adding
Medicine.Flocculent solving liquid is flocculant and tap water to be sufficiently stirred dissolving in dissolving tank, then pass through Pipeline transport to secondary settling tank
Or flocculation basin uses；White lime lysate is that quick lime and tap water are sufficiently stirred dissolving in dissolving tank, then defeated by pipeline
It send to homogeneous pond or comprehensive pool use.
Tap water is sent into dissolving tank after fully being dissolved with flocculant or quick lime by existing dosing transport system, then
Pass through Pipeline transport to chemical feeding points.As shown in Fig. 2, shut-off valve 2 is provided on the main line in 1 front of dissolving tank, in dissolving tank 1
It is sequentially connected in series shut-off valve 2, filter 3, metering pump 4, first manual on the main line at rear and adjusts pressure valve 5, pressure gauge 6, stream
After gauge 7, shut-off valve 2, it is separated into two branches and is connected to different chemical feeding points, and shut-off valve 2 is both provided on every roads Tiao Zhi.Meter
Amount pump 4 and first manual, which are adjusted, is connected to overflow branch for discharging extra lysate on the pipeline between pressure valve 5.Overflow branch
Road is equipped with second and adjusts pressure valve 8 manually, and the second Opening pressure for adjusting pressure valve 8 manually is more than first manual and adjusts pressure
The Opening pressure of power valve 5.When normal dosing, first manual adjusts pressure valve 5 and opens, and second adjusts pressure valve 8 manually closes, and one
When the pressure of denier main line has been more than setting value, second adjusts pressure valve 8 manually opens, and is discharged to extra lysate,
It causes to waste and pollutes environment；In addition, since Fluid pressure and instability of flow cause pipe vibration larger, there are downstream instrument
With the risk of equipment damage；Pressure gauge only display system pressure, the outlet pressures of flowmeter 7 can not be observed to obtain.
Utility model content
The utility model aims to solve the problem that extra lysate discharge waste and the pollution environment of existing dosing transport system, stream
The pipe vibration that body pressure and instability of flow are brought is larger and risk of equipment damage, flowmeter outlet end pressure can not be shown
Problem.
For this purpose, technical solution used by the utility model is：A kind of dosing transport system, the supervisor in front of dissolving tank
Road is provided with shut-off valve, and shut-off valve, filter, metering pump, first manual are sequentially connected in series on the main line at dissolving tank rear
After adjusting pressure valve, pressure gauge, flowmeter, shut-off valve, it is separated into two branches and is connected to different chemical feeding points, and on every roads Tiao Zhi
It is both provided with shut-off valve, the metering pump and first manual adjust and are also in series with pulsation damper on the pipeline between pressure valve,
It is connected to overflow branch between pulsation damper and first manual adjust pressure valve, the end of overflow branch is connected to filter and meter
Between amount pump, overflow branch road is equipped with second and adjusts pressure valve manually, and the second Opening pressure for adjusting pressure valve manually is more than
First manual adjusts the Opening pressure of pressure valve.
It is additionally provided on the main line between the filter and overflow branch end as a preferred embodiment of the above solution, unidirectional
Valve avoids the dissolving tank of overflow branch road from flowing back.
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) pulsation damper is added on main line, pulsation damper is a kind of for eliminating fluid pressure arteries and veins in pipeline
Dynamic or flow pulsation pressure vessel, can play stabilized fluid pressure and flow, eliminate pipe vibration, protection downstream instrument and
Equipment increases the effects that pump volumetric efficiency；
(2) end of overflow branch takes back on main line, the environmental pollution for avoiding lysate from wasting and bring；
(3) in addition to the pressure gauge display system pressure on main line, pulsation damper carries pressure display table, for showing
The pressure at flowmeter outlet end.
Description of the drawings
Fig. 1 is improved structural schematic diagram.
Fig. 2 is the structural schematic diagram before improving.
Specific implementation mode
By way of example and in conjunction with the accompanying drawings, the utility model is described in further detail：
As shown in Figure 1, a kind of dosing transport system, is provided with shut-off valve 2, molten on the main line in 1 front of dissolving tank
It solves and is sequentially connected in series shut-off valve 2, filter 3, metering pump 4, first manual adjusting pressure valve 5, pressure gauge on the main line at 1 rear of pond
6, after flowmeter 7, shut-off valve 2, two branches is separated into and are connected to different chemical feeding points, and shut-off valve is both provided on every roads Tiao Zhi
2, described above consistent with existing structure, details are not described herein.
Difference lies in：Metering pump 4 and first manual adjust and are also in series with pulsation damper 9 on the pipeline between pressure valve 5.
It is connected to overflow branch between pulsation damper 9 and first manual adjust pressure valve 5, the end of overflow branch is connected to filter 3
Between metering pump 4, overflow branch road is equipped with second and adjusts pressure valve 8 manually, and second adjusts the unlatching pressure of pressure valve 8 manually
Power is more than the Opening pressure that first manual adjusts pressure valve 5.
Preferably, it is additionally provided with check valve 10 on the main line between filter 3 and overflow branch end.Liquid in pipeline
Flow direction is as shown by arrows in figure.
In addition, filter 3 uses y type filters, metering pump 4 to use the Hydraulic Diaphragm Metering Pump of bottom in and top out.
