Description

A kind of acid alkaline titrimeter automatically
Technical field
The present invention relates to experimental apparatus technical field, specifically, relate to a kind of acid alkaline titrimeter automatically.
Background technology
In inorganic chemistry, analytical chemistry, biochemistry, microbiology, hereditism, life sciences and medical science Field, acid base titration operation to be carried out.Traditional acid base titration method, is to titrate by acid or alkali formula Pipe, dress liquid is relatively complicated and not accurate enough, often to carry out titration operation for a long time and (shake by hand during titration Conical flask, hand control flow rate of liquid), waste time and energy, not only operator's working strength is big, also someone will For error, experimental result reliability is poor.
Summary of the invention
It is an object of the invention to, it is provided that a kind of acid alkaline titrimeter automatically, to solve above-mentioned technical problem.
For solving the problems referred to above, the technical solution adopted in the present invention is:
A kind of acid alkaline titrimeter automatically, including for storing the liquid containing bottle of acid/base liquid, burette and for storing The liquid storage ware of liquid to be titrated, it is characterised in that: also include shell and the intelligent controller of case structure;Institute 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.
