| titleOfInvention | Constant-temperature digestion water quality chemical oxygen demand detection device |
| abstract | The utility model belongs to the field of water quality detection, in particular to a constant temperature digestion water quality chemical oxygen demand detection device, aiming at the problems that the digestion tank is heated by heating resistance wires in the existing heating mode, so that the temperature change, instability and the like of the digestion tank are easily caused, the utility model provides a scheme which comprises a digestion tank, a clapboard is fixedly arranged on the inner wall of the digestion tank in a sealing way, two flow pipes are fixedly arranged on the clapboard in a symmetrical sealing way, a circulating pump is fixedly arranged on the inner wall of the bottom of the digestion tank, the bottom ends of the two flow pipes are respectively fixedly connected with the water inlet end and the water outlet end of the circulating pump, a heating box is fixedly arranged on the flow pipes in a sealing way, and an installation box positioned below the clapboard is fixedly arranged in the digestion tank, the utility model can realize the cyclic heating of water, and can conveniently control the water temperature, so that the water can be detected in the later period, the problem of detection data occurrence caused by the problem of uneven water temperature can be avoided, and therefore the method has good practicability. |
