Utility model content
The purpose of this utility model is, provides a kind of acid alkaline titrimeter automatically, to solve above-mentioned technical matters.
For solving the problem, the technical scheme that the utility model adopts is:
A kind of acid alkaline titrimeter automatically, comprising the liquid storage bottle for storing acid/alkali lye, buret and the liquid storage ware for storing liquid to be titrated, it is characterized in that: the shell and the intelligent controller that also comprise case structure; Described liquid storage bottle is provided with at least two, and they are fixed on the top of shell inner cavity by holder; The inside of described shell inner cavity is provided with vibrating device; Described liquid storage ware is provided with at least one, is locked on vibrating device by geometrical clamp; The top of described buret is connected on the liquid outlet of liquid storage bottle, and the bottom of buret to extend in liquid storage ware and is fixed on the top mouth of liquid storage ware by web member, and the buret bottom mouth of pipe is connected with sharp mouth dropper; Described buret is provided with Micro-metering Pumps and autovalve from top to bottom successively; The bottom of described liquid storage ware inner chamber is provided with pH sensor; The front side wall of described shell is provided with display window and power light, left and right sidewall is respectively arranged with ventilative grid, left/right sidewall is provided with supply hub and power switch; Described display window comprises acid/alkali lye consumption liquid measure display window and the real-time display window of pH value; Intelligent controller is connected with supply hub by power switch; Described Micro-metering Pumps and pH sensor connect with the signal input part of intelligent controller respectively, and described autovalve, vibrating device, acid/alkali lye consumption liquid measure display window and the real-time display window of pH value connect with the signal output part of intelligent controller respectively.
Say further: described liquid storage bottle is also connected with steam hose, the other end mouth of pipe of described steam hose runs through and stretches out shell.
Beneficial effect: compared with prior art, the utility model is easy to operate, safe and reliable, only need on jolting device to place some liquid storage wares more, and be equipped with corresponding titration apparatus, just can realize multiple buret to operate simultaneously, even can carry out the titration operation of acid solution and alkali lye simultaneously, not only time saving and energy saving, and the accuracy of experimental result can be ensured.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
Fig. 2 position inner structure schematic diagram of the present utility model.
