Description
Technical field
The utility model belongs to electroplating wastewater processing technical field of liquid level measurement, and in particular to a kind of electroplating wastewater processing
With anti-interference liquid level emasuring device.
Background technology
Supersonic liquid level is calculated as a kind of equipment that waste water liquid level measures in wastewater equalization pond, as shown in figure 1, wastewater equalization pond
The ultrasonic level gage of top measures the height of waste water liquid level in wastewater equalization pond by the sensing of ultrasonic wave.
It is that all kinds of chemical industry electroplating wastewaters are collected wastewater equalization pond first during chemical industry electroplating wastewater processing
In 1, when high level is reached in wastewater equalization pond 1, the automatic start waste water lifting pump 5 of PLC control system 6 is drawn water to waste water reaction
Pond 7, mixer 8 automatically turns on operation in waste water reaction pond 7, while dosing pump 9 is automatically turned on toward addition medicament in reaction tank 7,
When waste water liquid level reaches low liquid level in wastewater equalization pond 1, PLC control system 6 closes waste water lifting pump 5 automatically makes it stop fortune
OK, mixer 8, dosing pump 9 are automatically stopped operation.
Wastewater surface in wastewater equalization pond 1 is caused to produce greatly due to containing exhibiting high surface activating agent in chemical industry electroplating wastewater
Foam is measured, and ultrasonic level gage 2 is to measure liquid level by the sensing of ultrasonic wave, substantial amounts of foam often misleads ultrasonic wave
The sensing of liquid level gauge 2, the liquid level for occurring measuring are actually the actual liquid of waste water in the height of foam, rather than wastewater equalization pond 1
Position, causes waste water lifting pump 5 that should be out of service to work on, and then cause waste water lifting pump 5 to frequently occur idle running damage
Motor, meanwhile, waste water lifting pump 5, which dallies, has had a strong impact on the normal operation of wastewater treatment, the nothing of mixer 8 in waste water reaction pond 7
Effect operation, dosing pump 9 excessively add unnecessary medicament, cause a large amount of wastes of electric energy and medicament, and had a strong impact on wastewater treatment
Effect.
Utility model content
To solve the deficiencies in the prior art, the utility model provides a kind of electroplating wastewater processing and filled with anti-interference level gauging
Put, the applying ultrasonic lever meter to measure that existing ultrasonic level gage can be overcome to trigger by the interference of a large amount of foams is inaccurate, causes to give up
The numerous idle running of water extraction liter pumping frequency, the invalid operation of mixer, dosing pump excessively add medicament, have a strong impact on lacking for water treatment effect
Fall into.
To solve the above problems, technical scheme provided by the utility model is：
A kind of anti-interference liquid level emasuring device of electroplating wastewater processing, includes wastewater equalization pond, ultrasonic level gage, enters
Waterpipe, waste water lifting pump, waste water reaction pond and PLC control system, sleeve pipe, the set are connected with the ultrasonic level gage
The end of pipe is less than height of the inlet channel from wastewater equalization pond bottom of pond from the height of wastewater equalization pond bottom of pond.
Further, to prevent sleeve pipe from being corroded by electroplating wastewater, described sleeve pipe uses the PVC sleeve pipes of acid and alkali-resistance.
Preferably, the end of described sleeve pipe is 30cm from the height of wastewater equalization pond bottom of pond, and the inlet channel is from waste water
The height of regulating reservoir bottom of pond is 35cm.
Operation principle of the present utility model is：
Because the end of sleeve pipe is less than height of the inlet channel from wastewater equalization pond bottom of pond from the height of wastewater equalization pond bottom of pond
Degree, can be such that the lower end of ultrasonic level gage is held at forever in waste water liquid level, when wastewater equalization pond liquid level produces macrofoam
When, ultrasonic level gage will not be influenceed by wastewater equalization pond liquid level foam, the height in a measuring unit intraluminal fluid face, due to set
Pipe connect always with the waste water of wastewater equalization pond, a large amount of foams will not be produced, thus applying ultrasonic lever meter to measure to cover intraluminal fluid
The height in face is the actual liquid level of wastewater equalization pond, and this would not mislead supersonic liquid level because of the presence of a large amount of foams
The actual liquid level of meter measurement wastewater equalization pond, also would not cause waste water because of the liquid level signal of ultrasonic level gage mistake
Elevator pump anhydrous operation, a series of problems for causing waste water lifting pump frequently to dally and triggering.
Compared with prior art, the utility model on ultrasonic level gage by setting sleeve pipe, and makes the end of sleeve pipe
Height from wastewater equalization pond bottom of pond is less than height of the inlet channel from wastewater equalization pond bottom of pond；Improve ultrasonic level gage
Measurement accuracy, while waste water lifting pump frequently idle running and the invalid operation of reaction tank mixer are avoided, it is more to save dosing pump
Remaining addition medicament, improves subsequent wastewater treatment effect.
