Description
Technical field
This utility model relates to a kind of chemical enterprise generally needs use to use some voltage stabilizing feedwaies more.
Background technology
During the tank field of fine chemistry industry enterprise batch production device uses at present, the control mode of single use point is
Applying highly developed and extensive, its technological process is: tank field → delivery pump → workshop.Due to Batch Process, often
Needs spent material when, started the delivery pump of the corresponding material in tank field by remote signal, be delivered to workshop by pipeline
Use point, such as measuring tank, reactor etc..Common control mode is: by arranging liquidometer, Weighing module or effusion meter
Measure etc. measuring instruments, when reaching to arrange value, automatically cut off inlet valve, and send termination of pumping signal to tank field.
Traditional this control mode the most reliably and easily operates in the case of this store list uses point, but when this material
In the case of more many workshops use and a little share, just become the most complicated.Mode controlled as described above, easily causes signal conflict, causes
The problem that can not solve very well to use a cross-reference during Design for Automatic Control Engineering more.
Utility model content
The purpose of this utility model is to provide one uses some voltage stabilizing feedwaies more, solves how to use often have pressure pipe pair
Use more and a little keep moment supply, it is not necessary to the technical problem to delivery pump frequent operation.
Use some voltage stabilizing feedwaies, including delivery pump, pressure maintaining tank, controller, liquidometer, piezometer, intake valve, pipe more
Road；Delivery pump is connected with the side of pressure maintaining tank by pipeline；Being provided with intake valve and piezometer on pressure maintaining tank, side is provided with liquid
Position is counted, and above-mentioned piezometer, liquidometer are all connected with controller, and this controller is for controlling the start and stop of delivery pump and opening of intake valve
Close.
It is communicated with a pipeline branch road between bottom and the conveying pipe of described pressure maintaining tank.
Described pipeline branch road centre position is the " u "-shaped of inversion 180 degree.
Described pressure maintaining tank top is also equipped with atmospheric valve.
The beneficial effects of the utility model are: owing to being provided with pressure maintaining tank, remained pressure, so in such tank body
Automatic feed can be realized in the case of having pressure in inlet valve open mode；Pump is opened, it is ensured that protect by arranging low liquid level limit
In pressure tank, material has not been pressed；By arrange high pressure limit termination of pumping, it is ensured that pressure inside the tank will not because liquid level rise and pressure superelevation；
By arranging low pressure values interlocking intake valve QI invigorating, it is ensured that material can be delivered to use point by overpressure all the time；By arranging peace
Full valve, prevents pressure inside the tank from exceeding pressure maintaining tank design pressure；By arranging bypass duct, so facilitate the maintenance of tank body.
Accompanying drawing explanation
Fig. 1 is the schematic diagram using some voltage stabilizing feedwaies more；
1. delivery pumps, 2. pressure maintaining tank, 3. controller, 4. liquidometer, 5. piezometer, 6. intake valve in figure, 7.
Pipeline, 8. bypass duct, 9. atmospheric valve, 10. relief valve.
Detailed description of the invention
Refer to Fig. 1, figure uses some voltage stabilizing feedwaies, including 1, pressure maintaining tank of a delivery pump 2, more
3, liquidometer of controller 4, piezometer 5, intake valve 6, a multiple pipeline 7.
Delivery pump 1 is connected with pressure maintaining tank 2 by pipeline 7；So material is first inputted in pressure maintaining tank 2.
Intake valve 6 and piezometer 5 are installed on pressure maintaining tank 2, there is in so making tank body certain pressure and detect tank simultaneously
The pressure in internal portion, and ensure that pressure is the most too low or too high.
The internal upper-lower position of pressure maintaining tank 2 is provided with liquidometer 4, and so when material reaches low liquid level, then controller 3 drives
Delivery pump 1 is opened beginning feeding and is entered in pressure maintaining tank 2, and when material reaches high pressure, then controller 3 cuts out delivery pump 1.In order to just
In the maintenance of pressure maintaining tank 2, a bypass duct 8 can be communicated with between the bottom of pressure maintaining tank 2 and conveying pipe.
As a example by liquid caustic soda is as raw material, the delivery pump 1 used before transformation is CQB65-50-160, flow 25m3/ h, lift
32m, power 7.5kW, maximum useful discharge 25m3/ h, minimum use flow 10m3/ h, the discharge pressure of least favorable point needs pressure head
0.3MPa.The delivery pump 1 used after transformation is CQB65-40-200, flow 25m3/ h, lift 50m, power 15kW.Set up one
The vertical vacuum tank of 5000L, Φ 1600 × 2000, total measurement (volume) about 5.07 m3.Low liquid level 200mm, low gas storage pressure are set
0.32MPa, gas storage volume 4.14 m；High gas storage pressure 0.50MPa is set, calculates high level 950mm, gas storage volume 2.63m
³.In two position changes, adjustable volume is about 1.51 m.In order to adapt to use the work a little used simultaneously during transformation more
Condition, can maintain the original state house steward's caliber after vacuum tank or suitably put bigger.
When initial start-up, medium need to be pumped in vacuum tank and make liquid level be higher than 200mm, and calculate institute according to air phase volume
Need air pressure, open aeration valve or atmospheric valve, make voltage stabilizing pressure inside the tank reach value of calculation.The most just controlled valve can be adjusted to automatically
Control.
This device is compared with the delivery pump before transformation, and maximum advantage is to simplify control program, it is possible to achieve use more
The situation of some cross-reference, adapts to carry from the indefinite flow of 0 ~ 25m/h, and even can exceed the quata in the short time conveying of constant current value, and
Stop the generation of liquid hammer phenomenon.2 times before although the operating power under delivery pump metered flow is transformation after Gai Zao, but due to
Before transformation, delivery pump efficiency when low discharge carries reduces, and after transforming, delivery pump runs in high efficiency operating mode always, actual fortune
The row electricity charge are how many than waste before transformation, and the most likely more save use than before transformation under frequent low discharge carries operating mode
Electricity.
Compare before and after table 1 transformation:
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, above in conjunction with this utility model
Accompanying drawing in embodiment, has carried out clearly and completely describing to the technical scheme in this utility model embodiment, it is clear that retouched
The embodiment stated is a part of embodiment of this utility model rather than whole embodiments.Generally described in the accompanying drawing herein and
