SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the technical deficiencies and providing a water environment's chemical oxygen demand monitoring devices, can realize intermittent type nature and detect the chemical oxygen demand of aquatic, the safety is stabilized to the transportation process moreover.
In order to achieve the above purpose, the utility model relates to a chemical oxygen demand monitoring device for water environment, which comprises a water environment unit and a chemical oxygen demand analyzer, and further comprises a temporary storage tank, wherein the temporary storage tank is connected with the water environment unit through a conveying water pipe, the conveying water pipe is communicated with the inside of the temporary storage tank, a conveying pump is arranged on the conveying water pipe, a solenoid valve is arranged on the conveying water pipe close to one end of the temporary storage tank, a discharge water pipe is arranged at the bottom of the temporary storage tank, the discharge water pipe is communicated with the temporary storage tank and the water environment unit, a discharge water pipe close to one end of the temporary storage tank is provided with a second solenoid valve, the chemical oxygen demand analyzer is provided with an input pipe and an output pipe, the input pipe extends to the inside of the temporary storage tank, the input pipe is provided with the second conveying pump, the output pipe is connected to the discharge water pipe between the second solenoid valve and the water environment unit, an overflow pipe is arranged at the top of the temporary storage tank, the overflow pipe is connected to a water discharge pipe between the second electromagnetic valve and the water environment unit, and an air pressure balance pipe is vertically arranged upwards at the top of the overflow pipe.
According to the technical scheme, the first electromagnetic valve and the second electromagnetic valve are controlled by the controller; when the chemical oxygen demand analyzer needs to carry out sampling detection, firstly, the second electromagnetic valve is opened, sample liquid in the temporary storage tank is completely emptied, then, the first electromagnetic valve is opened, the first conveying pump is simultaneously opened, water is conveyed to the temporary storage tank through the conveying water pipe and then is discharged through the discharge water pipe, the water staying in the conveying water pipe before is completely discharged after being continuously discharged for a certain time, namely, all water entering the temporary storage tank is extracted from fresh water in the water environment unit, then, the second electromagnetic valve is closed until the water in the temporary storage tank reaches a certain amount, and the first electromagnetic valve is closed. The process realizes sampling of a fresh water environment, then a small amount of sample liquid is conveyed to a chemical oxygen demand analyzer through a second conveying pump for chemical oxygen demand analysis, an analysis result is obtained, and the analyzed sample liquid is conveyed to a discharge water pipe for discharge. When the temporary storage tank is arranged, the horizontal position of the temporary storage tank can be higher than that of the water environment unit, so that water in the temporary storage tank can be automatically discharged by utilizing gravity in the discharging process, the energy consumption is reduced, and the cost is saved.
Be provided with on the jar of keeping in and stay the appearance pipe, stay the appearance pipe and extend to the jar of keeping in inside, be provided with No. three delivery pumps on staying the appearance pipe, be provided with at least one on staying the appearance pipe and stay the appearance and divide the pipe, still including staying the appearance bottle, stay the appearance bottle and stay the appearance and divide a tub one-to-one, stay the appearance and divide the pipe to extend to the corresponding sample bottle that stays. The design of this structure can be under the condition that chemical oxygen demand analyzer testing result exceeds standard, can carry the partial sample liquid in the jar of keeping in to staying the appearance bottle in through No. three delivery pumps to evidence such as environmental protection department. Of course, a plurality of sample retention bottles can be adopted, and each sample retention branch pipe is provided with an electromagnetic valve for distribution and use of the sample retention bottles, so that multiple sample retention is realized.
The utility model discloses the chemical oxygen demand monitoring devices of water environment that obtains can realize carrying out intermittent type nature to the chemical oxygen demand of water environment unit and detect, monitor, and detect the analysis process at every turn and all adopt fresh appearance liquid in the water environment to ensure the accuracy that detects, can also keep a sample simultaneously.
