Stating liquid containing bottle and be provided with at least two, they are fixed on the top of shell inner cavity by fixing seat；In described shell
Chamber be internally provided with vibrating device；Described liquid storage ware is provided with at least one, is locked by fixation clamp
On vibrating device；The top of described burette is connected on the liquid outlet of liquid containing bottle, and the bottom of burette is stretched into
Being fixed in the top opening of liquid storage ware in liquid storage ware and by connector, connecting on the mouth of pipe of burette bottom has
Point mouth dropper；Micro-metering Pumps and automatic valve it is sequentially installed with from top to bottom on described burette；Described liquid storage
The bottom of ware inner chamber is provided with pH sensor；Display window and power supply instruction are installed on the front side wall of described shell
Lamp, left and right sidewall is respectively arranged with ventilative grid, is provided with supply hub and power supply on left/right sidewall
Switch；Described display window includes acid/base liquid consumption liquid measure display window and the real-time display window of pH value；Intelligent controller
Connected with supply hub by and off switch；Described Micro-metering Pumps and pH sensor respectively with Based Intelligent Control
The signal input part of device connects, described automatic valve, vibrating device, acid/base liquid consumption liquid measure display window and pH value
Display window connects with the signal output part of intelligent controller respectively in real time.
Say further: described liquid containing bottle is also associated with steam hose, the other end mouth of pipe of described steam hose
Run through and stretch out shell.
Beneficial effect: compared with prior art, the present invention is easy to operate, safe and reliable, and only needing will be in shaking
Many some liquid storage wares of placement on device, and it is equipped with corresponding titration appratus, so that it may realize multiple burette simultaneously
Operation, it might even be possible to simultaneously carry out the titration operation of acid solution and alkali liquor, the most time saving and energy saving, and can protect
The accuracy of card experimental result.
Accompanying drawing explanation
Fig. 1 is the perspective view of the present invention；
The internal structure schematic diagram of Fig. 2 position present invention.
Detailed description of the invention
The invention will be further described with detailed description of the invention below in conjunction with the accompanying drawings.
With reference to Fig. 1, Fig. 2, automatic acid alkaline titrimeter of the present invention, including the storage for storing acid/base liquid
Liquid bottle 6, burette 9 and for storing the liquid storage ware 8 of liquid to be titrated, the shell 1 of case structure and intelligence
Controller, in the present embodiment, liquid storage ware 8 uses conical flask.
Described liquid containing bottle 6 is provided with two, and they are fixed on the top of shell 1 inner chamber by fixing seat 7.Institute
That states shell 1 inner chamber is internally provided with vibrating device 10.Described liquid storage ware 8 is provided with two, passes through fixation clamp
11 are locked on vibrating device 10.The top of described burette 9 is connected on the liquid outlet of liquid containing bottle 6,
It is fixed in the top opening of liquid storage ware 8 in the bottom of burette 9 extend into liquid storage ware 8 and by connector 81,
The burette 9 bottom mouth of pipe connects and has sharp mouth dropper 93, make point mouth dropper 93 firm fixing by clip
Inside liquid storage ware 8.Described liquid containing bottle 6 is also associated with steam hose 61, another of described steam hose 61
The end mouth of pipe runs through and stretches out shell 1.
Micro-metering Pumps 91 and automatic valve 92 it is sequentially installed with from top to bottom on described burette 9；Described liquid storage
The bottom of ware 8 inner chamber is provided with pH sensor 82；On the front side wall of described shell 1, display window 2 is installed
With power supply indicator 4, left and right sidewall is respectively arranged with ventilative grid 3, right side wall is provided with power supply
Jack 5 and on and off switch 51；Described display window 2 includes that acid/base liquid consumption liquid measure display window 21 and pH value are real-time
Display window 22；Intelligent controller is connected with supply hub 5 by and off switch 51；Described Micro-metering Pumps
91 and pH sensor 82 connect with the signal input part of intelligent controller respectively, described automatic valve 92, shake
Dynamic device 10, acid/base liquid consumption liquid measure display window 21 and the real-time display window of pH value 22 respectively with intelligent controller
Signal output part connect.
The acid/base liquid flowed out in described liquid containing bottle 6 is measured by Micro-metering Pumps 91, can by automatic valve 92
Control liquid flowing, realize ventilation by steam hose 61, can realize automatically controlling and measuring, need not be artificial
Carry out associative operation；Realized the shaking of liquid storage ware 8 by vibrating device 10, free from artificial shaking；
By the situation of change of pH value in pH value real-time display window 22 real-time monitored liquid storage ware 8, when arriving titration
Close automatic valve by intelligent controller during terminal, stop liquid feeding, read by acid/base liquid consumption liquid measure display window 21
Go out consumable liquid amount.
When needs carry out pipe flushing, steam hose 61 can be received and can realize at cleanout fluid rinsing；When
When needing to carry out liquid storage, in liquid containing bottle 6, fill acid/base liquid by steam hose 61.
