Specific embodiment
This utility model wire 3 connects the conductive sponge of each sample point respectively, connects DC12V in the holding wire other end
Relay module, then by DC12V relay module, the switching signal after changing is sent to PLC module and thus controls each equipment
Start and stop.
The specific implementation step of middle-size and small-size Sewage Disposal tank level control system：
1st, determine user will be controlled to sewage disposal device using which kind of mode (as PLC control, light current letter first
Number mode such as control, heavy-current control), then determine corresponding technological process and specific embodiment again.
2nd, according to scene and user require make signal conversion and control cabinet, and pilot scale study qualified after use.
3rd, require to make the connection work of conductive sponge and transmission holding wire with corresponding peace mark code according to related process
(conductive sponge is tin plating with holding wire junction).
4th, in each sewage reaction tank, positioning conductive sponge sensor probe is installed according to live actual operation requirements.
The operation principle of middle-size and small-size Sewage Disposal tank level control system：
It is the part by the use of measured medium itself as common signal, when measured medium liquid level reaches in measured medium liquid level
During to extreme high water level signal position, water process internal unit is out of service, and feed pump stops fortune in running status, automatic water-replenishing device
OK；When measured medium liquid level drops to high water level signal position, water process internal unit startup optimization, feed pump is running shape
State, automatic water-replenishing device is out of service；When measured medium liquid level continues to drop to automatic water supplement signal position during sponge, feed pump
Out of service, automatic water-replenishing device startup optimization, water process internal unit is in running status；Continue to decline in measured medium liquid level
During to low liquid level signal position, feed pump is out of service, and automatic water-replenishing device is running shape in running status, water process internal unit
State；When measured medium liquid level rises, when reaching automatic water supplement liquid level signal position, feed pump startup optimization, automatic water-replenishing device
Out of service, water process internal unit is in running status；When measured medium liquid level continuously rises to high water level signal position, supply water
, in running status, automatic water-replenishing device is out of service for pump, and water process internal unit is in running status；Continue in measured medium liquid level
When rising to extreme high water level signal position, in running status, automatic water-replenishing device is out of service for feed pump, and water process internal unit stops
Only run.Complete a cycle of operation simultaneously.
This utility model employ the novel process facility such as " conductive sponge ", " relay module " it is characterised in that：
The operation principle of DC12V relay module is to be triggered using low level signal, and the direct triggering mode that this just uses in early stage is complete
Entirely different, because low level signal triggering mode is one pole triggering, the approximate OV of trigger voltage, trigger current maximum only 0.08mA
(in use for laboratory standard signal calibration result, calibrating installation is that secondary numerical monitor controls calibrating installation), such experiment knot
Fruit fully meets our use requirement.The electrolytic oxidation degree being approximately 0 has been reached in measured medium.We use simultaneously
Conductive sponge be first in tank level control system use, because conductive sponge is to be given birth to by polymer composite foaming technique
Produce, foaming uniform pore diameter, softness, high resilience, not desquamation, the even distribution of conductive sponge has corrosion resistance, is long
The perfect medium material that phase uses.To have a conductive effective phase long for conductive sponge simultaneously, and conductive sponge is not subject to temperature and humidity
Impact, sheet resistance value can by practical use customized the features such as.Divide high density and low-density two class.High density：For testing, insert
Integrated circuit, can do the conduction having high demands and antistatic packaging material low-density：Shockproof for having, the electronics that antistatic requires
Product packaging；Conductive sponge sheet resistance：≤ 103-5 Ω, Anti-static sponge sheet resistance：≤1011Ω；It is widely used in：Meter
Calculation machine, LCD display, LCD TV, laser printer, high speed copier, communication apparatus, mobile phone, satellite communication, medical treatment
The test of equipment high-pressure unit, instrument, pad/dividing plate, plate electronic product, shockproof conductive packaging；And relatively low 10 yuan of cost/
Rice.Improve service precision and the usage cycles of tank level control system, be mounted simultaneously for this than less expensive it is adaptable to middle-size and small-size dirt
In water treatment system.Simultaneously during making liquid level controller power distribution cabinet, we will make liquid level controller and ball float by oneself again
Liquid level controller accomplishes to have accomplished " the using and the reserved " state together, with system malfunctions (is just enclosed within when a certain in two sets of systems
Be water level signal not according to, occur bypassing the immediate leadership from low to high or from high to low display when), switch board will automatically switch to other one
Set system operation.We have also installed alarm device additional simultaneously, be can reflect in time when breaking down equipment fault former
Cause.Its operation principle is：Under normal circumstances, sensor is closed main power, 12V DC source, sensor control power supply, without
Close ball float and control power supply, only 12V D.C. regulated power supply, relay module, the multigroup relay devoted oneself to work in such a mode
Device, control signal is conductive sponge；When closing, ball float controls power supply, and sensor is no longer controlled the start and stop of each electrical equipment,
Switch to ball float control, achievable quick-replaceable.
It should be appreciated that above detailed description the technical solution of the utility model being carried out by preferred embodiment is to illustrate
Property and nonrestrictive.Those of ordinary skill in the art can be to enforcement on the basis of reading this utility model description
Technical scheme described in example is modified, or carries out equivalent to wherein some technical characteristics；And these modification or
Replace, do not make the essence of appropriate technical solution depart from the spirit and scope of this utility model embodiment technical scheme.
