Abstract
The utility model provides an underwater aeration equipment failure early warning device. A stress sensor is installed on the front of aeration disk gas outlet holes of the aeration equipment through a support, the stress sensor is packaged in a flexible waterproof jacket, the stress sensor is connected with a data processing unit, and the data processing unit and the starting circuit of the aeration equipment both are connected with a programmable controller. In the operational process of the aeration equipment, the stress sensor is used for detecting the stress generated by the gas exhausted from the aeration disk gas outlet holes on a real time basis, the stress signal is inputted to the data processing unit for processing, the processed data is inputted to the programmable controller, if the detected stress value is lower than a set value, then the programmable controller is used to cause the aeration equipment to stop running automatically, and an alarm signal is generated immediately. According to the utility model, the on-line and real-time detection of the aeration disk gas exhausting stress of the underwater aeration equipment can be realized, data processing can be performed, and early warning and alarm can be automatically performed on failures according to the detected stress.
Description
Technical field
The utility model relates to and a kind of the aerator under water that is used for wastewater treatment is carried out the method and apparatus of fault pre-alarming, belongs to sewage disposal device fault pre-alarming technical field.
Background technology
In sewage treatment industry, commonly used to various aerators, like suspended chain aerator, aeration plate in all aerators or aeration tube all will go deep under water.In the operational process of aerator, because sewage is comparatively muddy, can't accurately judge the running status of aeration plate,, can't find in time also that situation inhomogeneous or that the part aeration plate blocks often occurs giving vent to anger even break down.
At present, various aerators all are not provided with the fault pre-alarming device.
Summary of the invention
The utility model to existing aerator in operational process, exist can't be to the problem of fault pre-alarming; Providing a kind of can carry out early warning, guarantee the normal fault early warning method of aerator under water that moves of equipment fault automatically, and a kind of fault pre-alarming device of realizing this method is provided simultaneously.
The fault pre-alarming of the aerator under water device of the utility model, adopt following technical solution:
This prior-warning device comprises strain gauge, data processing unit and PLC Programmable Logic Controller, and strain gauge is connected with data processing unit, and data processing unit is connected with the PLC Programmable Logic Controller, and strain gauge is wrapped in the flexible anti water jacket.
When said apparatus is used; Strain gauge is installed on the support; This support is fixed on the aeration plate, makes between the venthole of strain gauge and aeration plate to have certain distance, and strain gauge can detect the venthole of aeration plate and discharge the stress that gas produces.The start-up circuit of aerator also is connected with the PLC Programmable Logic Controller simultaneously.When aerator running work; Strain gauge detects the stress of giving vent to anger of aeration plate venthole, is input to Programmable Logic Controller after the data processing unit counter stress signal Processing, after Programmable Logic Controller receives data; Automatically analyze; When the stress of giving vent to anger that detects the aeration plate venthole is reduced to setting value when following, Controlled by Programmable Controller aerator under water is out of service, and sends alerting signal immediately.
The utility model can realize that the give vent to anger online in real time of stress of aerator aeration plate under water detects, and carries out data processing, and arrestment operation automatically, automatically fault is carried out early warning and warning, has guaranteed the normal operation of aerator.
Description of drawings
Fig. 1 is the utility model structural principle synoptic diagram of aerator fault pre-alarming device under water.
Wherein: 1, strain gauge, 2, data processing unit, 3, Programmable Logic Controller, 4, aerator.
Embodiment
As shown in Figure 1; The fault pre-alarming of the aerator under water device of the utility model; Comprise strain gauge 1, data processing unit 2 and Programmable Logic Controller 3; Strain gauge 1 is connected with data processing unit device 2 through data line, and data processing unit 2 is connected with Programmable Logic Controller 3 through data line, and strain gauge 1 is wrapped in the flexible anti water jacket.Strain gauge 1 is installed on the support, and this support is fixed on aerator 4 and is on the aeration plate of underwater portion, makes between the venthole of strain gauge 1 and aeration plate to have certain distance, and this distance can be confirmed according to experiment or experience.Data processing unit 2 not in water, water-proofing treatment that it goes without doing.
Said apparatus is described below to the process of aerator fault pre-alarming under water:
In aerator 4 operational processs; Strain gauge 1 detects the stress of the generation of aeration plate gas that venthole is discharged in real time; And the stress data that detects is input to data processing unit 2 handles; Data input Programmable Logic Controller 3 after data processing unit 2 will be handled, 3 pairs of these data analysis of Programmable Logic Controller.When cause the stress of giving vent to anger of aerator aeration plate venthole to be reduced to setting value (this setting value can be set according to experiment or experience) when following because of certain reason (block or damage) like aeration plate; Explain that aeration plate breaks down; Programmable Logic Controller 3 control aerators 4 are out of service automatically, and send alerting signal immediately, and the prompting staff checks the scene; Handle, thereby reach accurate early warning aerator fault whether purpose.
