The utility model content
The utility model provides the online ammonia nitrogen constant temperature of a kind of water quality hybrid measurement device; Adopt long pipe runs mixing and pipeline to embed the mode in the heating plate; The realization sample mix is even, is rapidly heated, and keeps constant temperature; Avoid the stream bubble to disturb, avoid environment temperature ammonia gas-sensing electrode drift in water sample is measured.Improve gas sensing electrode accuracy and reappearance.
In order to reach above-mentioned purpose of design, the technical scheme that the utility model adopts is following:
The online ammonia nitrogen constant temperature of a kind of water quality hybrid measurement device; Comprise the constant temperature substrate; Said constant temperature substrate inside is equipped with circuit control panel and heating plate; Said constant temperature substrate front side is equipped with mixed pipe line, gas sensing electrode and the gas outlet that is connected with flow cell respectively, and said constant temperature substrate back is equipped with liquid-pressure pick-up and the sample introduction pipeline that is connected with mixed pipe line successively.
The positive back side of constant temperature substrate is equipped with corresponding grooves, its inner circuit control panel and heating plate installed.
Several sample introduction pipelines link to each other with liquid-pressure pick-up; It is a mixed pipe line that sample introduction pipeline through liquid-pressure pick-up compiles, and sample introduction pipeline, liquid-pressure pick-up, mixed pipe line all adopt carries out embedded being installed on the constant temperature substrate back in the corresponding groove.Mixed pipe line extends to the front of constant temperature substrate along the edge of constant temperature substrate, be attached in the constant temperature substrate front side corresponding grooves with repeatedly folding mode embedding.
After mixed pipe line extended to the front of constant temperature substrate, folding through repeatedly, its end was connected with flow cell, and the flow cell other end connects gas sensing electrode.Flow cell and gas sensing electrode and surface level keep certain angle of inclination.Gas outlet is installed in the side of flow cell, and gas outlet keeps vertical with surface level.

Embodiment
Below in conjunction with accompanying drawing the optimum implementation of the utility model is done further detailed description.
Like Fig. 1, shown in 2; The online ammonia nitrogen constant temperature of the described a kind of water quality of the utility model embodiment hybrid measurement device; Comprise constant temperature substrate (1); Said constant temperature substrate (1) inside is equipped with circuit control panel (6) and heating plate (5), and said constant temperature substrate (1) front is equipped with mixed pipe line (3), gas sensing electrode (8) and the gas outlet (9) that is connected with flow cell (2) respectively, and said constant temperature substrate (1) back side is equipped with liquid-pressure pick-up (7) and the sample introduction pipeline (4) that is connected with mixed pipe line (3) successively.
During use, different test fluid gets into this device from each sample introduction pipeline (4) respectively, when test fluid is passed through liquid-pressure pick-up (7); Can learn the pressure and the flow of test fluid; Behind the test fluid stream process liquid-pressure pick-up (7), gather inflow mixed pipe line (3), be able to abundant mixing.
Mixed pipe line (3) extends to the front of constant temperature substrate (1), is attached in the positive groove of constant temperature substrate (1) with repeatedly folding mode embedding, reaches with this to prolong mixed pipe line (3) length, realizes fully heating, being rapidly heated, and keeps the purpose of temperature.
After mixed pipe line (3) extends to the front of constant temperature substrate (1), its terminal flow cell (2) and gas sensing electrode (8) of connecting, flow cell (2) and gas sensing electrode (8) keep certain angle with surface level, avoid the interference of bubble.Gas outlet (9) is installed in the side of flow cell (2), and gas outlet (9) generally keeps vertical with ground.
This embodiment is the preferred embodiment of the utility model, can not limit the utility model, and concrete each item rights protection scope is defined by the claims.
