Description
Technical field
The novel reflux relating to COD in Monitoring And Analysis of The Quality field of this experiment, particularly a kind of can the COD reflux of batch operation.
Background technology
COD is as one of environmental factors, and the COD ten points measured in sample is accurately important, and traditional reflux uses iron stand to fix, and the poor stability of device takes up room large, inconvenient operation.In real work, sample size is comparatively large, needs the stability of assurance device, needs to carry out organizing sample tests more simultaneously, increase work efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of stability strong and can the COD reflux of batch operation.The utility model improves the stability of experimental provision, simplifies installation procedure, easy to operate, can realize the batch operation of sample, improve work efficiency.
The utility model is made up of experiment table, condenser pipe fixed mount, adjustable electric furnace, ground backflow conical flask, condenser pipe, silicone tube and beaker, multiple adjustable electric furnace is placed on experiment table, each adjustable electric furnace is placed ground backflow conical flask, condenser pipe is spherical condensation tube, condenser pipe is fixed on condenser pipe fixed mount, lower end and the ground of the condenser pipe conical flask that refluxes is connected, and communicated by silicone tube between condenser pipe, condenser pipe upper end covers beaker.
The course of work of the present utility model:
Testing sample joins in 250ml ground backflow conical flask, and adds potassium dichromate standard solution and beaded glass, and add 30ml sulfuric acid-silver sulfate solution through condenser pipe is suitable for reading, in condenser pipe, water (flow) direction follows bottom in and top out principle.
The beneficial effects of the utility model:
1, improve work efficiency: can reflux multiple testing sample simultaneously, improves the test speed of batch sample, effectively raise work efficiency.
2, improve stability and the security of device: classic method uses iron stand stationary installation, device assembling is more loaded down with trivial details, poor stability, operate inconvenience, easily make device loosen in condenser pipe in water flow process, may cause the failure of testing, this experiment is novel to be placed on condenser pipe in condenser pipe fixed mount, effectively secure condenser pipe, add stability and the security of whole device.
3, space has been saved: traditional experimental provision takes up room comparatively large, the novel space can saved greatly shared by experimental provision of this experiment.
The utility model simple and safe operation, has saved lab space, has ensured the safety of experimenter, has effectively raised work efficiency.
