Abstract
An automatic liquid feeding titration device belongs to the technical field of assay titration analysis device. The current ordinary acid burette has the disadvantages of leakage, foaming, complicated operation, repeated zero filling, easy error generation, large amount of waste liquor and large pollution. The device has the technical proposal that, one end of a dropping liquid sharp mouth (7) with a titration control valve (6) is fixedly connected and communicated with a titration tube (3) with a liquid supply valve (5); one end of the titration tube (3) fixed on the bottle cap is inserted into a liquid storage bottle (1); a manual pneumatic compression pump (4) is arranged on the bottle cap of the liquid storage bottle (1); an automatic zero filling sharp mouth (8) is fixedly connected and communicated with the titration tube (3); one end of an acid resistant plastic tube (9) is fixedly connected and communicated with the automatic zero filling sharp mouth (8), and the other end is inserted into a recovery bottle (2). The device has the advantages of high measuring accuracy of automatic zero filling, reagent saving, little waste liquor discharge, automatic liquid feed, simple operation, time and labor saving and greatly improved working efficiency.
Description
Technical field
The utility model relates to chemical examination titrimetry device technique field, is a kind of automatic titration apparatus more specifically.
Background technology
The shortcoming of the conventional acid buret of use is now: easy-to-leak liquid, easily produce bubble, and troublesome poeration (when dropping liquid uses up, needing on the titration folder, take off repeatedly the injection standard solution), fixed repeatedly zero, easily produce error, the waste liquid of generation to be polluted greatly.
Summary of the invention
For overcoming above-mentioned shortcoming, the purpose of this utility model is a kind of automatic titration apparatus of design.Its technical scheme is: the dropping liquid point mouth of band titration operation valve is fixedly connected with the buret of band supplying valve, an end that is fixed on the buret on the bottle cap inserts in the liquid storage bottle, manually the inflation force (forcing) pump is installed on the bottle cap of liquid storage bottle, automatic zero-filling point mouth and buret are fixedly connected, one end of acidproof plastic tube and automatic zero-filling point mouth are fixedly connected, and its other end inserts in the returnable bottle.The advantage of this utility model is: reasonable in design, and the novelty that is skillfully constructed, this device automatic zero-filling is measured the precision height, and it is few to save the reagent discharging of waste liquid, and liquid feeding is simple to operation automatically, and saving time saves trouble increases work efficiency greatly.
Description of drawings
This accompanying drawing is the utility model structural representation.In the accompanying drawing: 1, liquid storage bottle, 2, returnable bottle, 3, buret, 4, manually inflate force (forcing) pump, 5, supplying valve, 6, the titration operation valve, 7, dropping liquid point mouth, 8, automatic zero-filling point mouth, 9, acidproof plastic tube.
Embodiment
The dropping liquid point mouth 7 of band titration operation valve 6 is fixedly connected with the buret 3 of band supplying valve 5, an end that is fixed on the buret 3 on the bottle cap inserts in the liquid storage bottle 1, manually inflation force (forcing) pump 4 is installed on the bottle cap of liquid storage bottle 1, automatic zero-filling point mouth 8 is fixedly connected with buret 3, one end of acidproof plastic tube 9 and automatic zero-filling point mouth 8 are fixedly connected, and its other end inserts in the returnable bottle 2.Standard solution is added in the liquid storage bottle 1, close titration operation valve 6, open supplying valve 5, make solution realize automatic pressurized fluid in the buret 3 with manual inflation force (forcing) pump 4 pressurizations by slowly flowing in the liquid storage bottle 1, when solution is full of and when automatic zero-filling point mouth 8 is discharged surplus liquid, close supplying valve 5, realize automatic zero set (AZS) when surplus liquid stops to discharge; Open titration operation valve 6 when carrying out titrimetry, standard solution is oozed from dropping liquid point mouth 7 carry out titration and get final product.
Claims (1)
1, a kind of automatic titration apparatus, it is characterized in that: the dropping liquid point mouth (7) of band titration operation valve (6) is fixedly connected with the buret (3) of band supplying valve (5), an end that is fixed on the buret (3) on the bottle cap inserts in the liquid storage bottle (1), manually inflation force (forcing) pump (4) is installed on the bottle cap of liquid storage bottle (1), automatic zero-filling point mouth (8) is fixedly connected with buret (3), one end of acidproof plastic tube (9) and automatic zero-filling point mouth (8) are fixedly connected, and its other end inserts in the returnable bottle (2).
