Abstract
The utility model discloses a novel constant-temperature water bath testing device used for corrosion electrochemical tests in labs and solves the problem that alternating electricity generated from electrical heating and stirring in the conventional water bath kettle generates a magnetic field to disturb electrochemical signals, leading to an inaccurate test result. The novel constant-temperature water bath testing device comprises a glass water bath cylinder. A water inlet is formed in the lower portion of the water bath cylinder, and an overflow hole is formed in the upper portion of the water bath cylinder. An electrolytic cell tray is hung in the water bath cylinder. A bubble outlet screen is arranged at the bottom of the water bath cylinder and is a chamber with the surface provided with a plurality of air outlets. The chamber is in linkage with an air inlet. The glass water bath cylinder facilitates test operations and observations. By external temperature control equipment, circulating constant-temperature hot water is provided. By air bubbles, stirring with uniform heat is achieved so as to eliminate a disturbance source in electrochemical measurement and improve test accuracy.
Description
Technical field
The utility model relates to a kind of solution temperature controlling instruments for testing laboratory's corrosion electrochemistry test, relates in particular to a kind of novel constant-temperature bathtub test device.
Background technology
The corrosion test of carrying out in testing laboratory, all adopts thermostat water bath miscellaneous to carry out temperature control, but these water-baths mostly adopt electric heating tube to heat, and adopts water pump that the water in water-bath is circulated, and reaches the object of soaking in water-bath.
Adopt electrochemical method to carry out corrosion behavior while measuring, as method of polarization curve, often need electrolytic cell to put into water-bath, to keep the constant of electrolyte solution temperature in process of the test.Electrochemical measurement general signal is very weak, and the electric heating tube in water-bath heats, in pumping for water pump process, and the alternating current of use can produce magnetic field, and electrochemical signals is played to interference effect, sometimes can make test be difficult to carry out or to the test findings making mistake.
Summary of the invention
The purpose of this utility model is to overcome prior art defect, and a kind of novel constant-temperature bathtub test device is provided, and can remove electrolytic cell interference source around, makes electrochemical measurement signal interference-free.
The technical solution of the utility model is achieved in that novel constant-temperature bathtub test device, comprises cleansing bath tub, and it is, in cleansing bath tub bottom, is provided with inlet opening, and top is provided with spillway hole, and the hanging of electrolytic cell pallet is in cleansing bath tub.
Further, be placed with bubble outlet sieve in the bottom of cleansing bath tub, bubble outlet sieve is the cavity that surface is furnished with a plurality of ventholes, and cavity connects with air admission hole.
Further, cleansing bath tub is clear glass material.
The utility model adopts bath of glass bathtub, is convenient to test operation and observation, uses outside temperature controlling instruments that the constant-temperature hot water of circulation is provided, and adopts air bubble to carry out equal thermal agitation, has eliminated the interference source of electrochemical measurement, has improved the accuracy of test.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, 1-air admission hole; 2-inlet opening; 3-spillway hole; 4-bubble outlet sieve; 5-electrolytic cell pallet; 6-cleansing bath tub.
Embodiment
Below in conjunction with accompanying drawing, be further described:
As shown in Figure 1, novel constant-temperature bathtub test device, comprise bath of glass bathtub 6, in cleansing bath tub 6 bottoms, be provided with inlet opening 2, top is provided with spillway hole 3, in the upper cover hanging of cleansing bath tub 6, has electrolytic cell pallet 5, places the bubble outlet sieve 4 of pie in the bottom of cleansing bath tub 6, bubble outlet sieve 4 is the surperficial cavity that is furnished with a plurality of ventholes, and cavity connects with air admission hole 1.
Before on-test, the thermostatted water providing from outside thermostatic equipment by inlet opening 2 inputs, when water level rises to spillway hole 3, water is discharged from spillway hole 3, flows back to outside thermostatic equipment, realizes the water circulation between water bath with thermostatic control and outside thermostatic equipment.Pressurized air flows into from air intake opening 1, exports sieve 4 be discharged in thermostatted water by bubble, and the bubble agitation thermostatted water of rising, to realize the soaking of thermostatted water in cleansing bath tub 6.Electrochemical test is placed on electrolytic cell pallet 5 with electrolytic cell, can keeps the constant of electrolyte solution temperature in process of the test.
