Technical field

The utility model belongs to COD detection technique field, is specifically related to a kind of COD detector.

Background technology

COD is also called chemical oxygen demand (COD), and be the important indicator representing that in water, reducing substances is how many, the reducing substances in water has various organism, nitrite, sulfide, ferrous salt etc.But importantly organism.Therefore, chemical oxygen demand (COD) (COD) is again often as weighing the how many index of Organic substance in water matter content.Chemical oxygen demand (COD) (COD) is larger, illustrates that water body is more serious by organic pollution.But the detection method of traditional C OD generally adopts backflow to clear up titrimetry, length consuming time, power consumption is large, cost height and inefficiency are all the key factors affecting its development, later stage user adds oxygenant and catalyzer improves speed, but effect is still undesirable, and needs are artificially measured when adding distilled water, there is certain error, repeatedly the discontinuous work of sequence is easy to cause the error in measuring process larger, affect the judged result of user, artificial colorimetric is needed after measurement, this is also one of error, in order to improve the accuracy that COD detects, these weak points all have much room for improvement.

Utility model content

The purpose of this utility model is to provide a kind of COD detector, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technical scheme: a kind of COD detector, comprise guard shield, microprocessor, heating and decompose device, operation panel, COD curve tester, autovalve, cooling bath, oscillator, micro pump, distilled water tank and louvre, described autovalve is arranged on the inner tip of guard shield, described microprocessor, COD curve tester and distilled water tank are arranged on the bottom of guard shield, described micro pump is arranged on the top of distilled water tank, described micro pump is connected by water pipe with autovalve, described heating and decompose device and cooling bath are installed in the inside of guard shield, described oscillator is arranged on the bottom of cooling bath, described heating and decompose device, COD curve tester, autovalve, oscillator and micro pump are all electrically connected with microprocessor, described operation panel is arranged on the front of guard shield, described louvre is arranged on the left side of guard shield.

Preferably, described heating and decompose device and cooling bath are evenly provided with the test tube fixed orifice of several equidimensions, the corresponding test tube being provided with suitable dimension respectively on described test tube fixed orifice.

Preferably, described operation panel is made up of LCDs, USB connection jaws, amplify warning horn and operation keyboard.
