Description
Technical field
The invention belongs to electromechanical integration technology area, relate to a kind of device that prevents that in solution, detecting electrode lost efficacy.It can effectively avoid detecting electrode in solution to lose due measurement function because solute crystallization or impurity adhere to.At present of a great variety for detection of the electronic instrument of the various parameters of solution, quantity is huge.But in use, because solution environmental reason of changes can cause the crystallization adhering on detecting electrode such as solute or impurity, thereby cause electrode failure to affect the normal work of detection system.
Background technology
All can utilize various solution to produce at industry fields such as metallurgy, chemical industry, biologic product, pharmacy and aquatic products, be important method and the means of production process control to the parameter control of solution.Production process control normally by laying such as temperature, salinity, electrical conductivity, PH and various ion transducer in solution, by the variation of sensor senses solution parameter, and start or stop control appliance and guarantee that the parameter of solution meets the requirement of production.
Because various sensors are placed in solution for a long time, and in production process the parameter such as solute, temperature, PH and electrical conductivity of solution in continuous variable condition.Therefore the outer wall of sensor very easily adheres to solute crystallization or impurity particle and causes sensor detection sensitivity to reduce even to lose efficacy, thereby affects the quality of production.
Therefore prevent that in solution, detecting electrode lost efficacy, or the working life of prolongation detecting electrode is significant for the industry fields such as metallurgy, chemical industry, biologic product, pharmacy and aquatic products.
Summary of the invention
The present invention is directed to the reality of short, easy inefficacy of the online detecting electrode life-span of detecting of solution parameter in the industries such as current metallurgy, chemical industry, biologic product, pharmacy and aquatic products, provide a kind of safe, convenient, use simple, the with low cost device that prevents detecting electrode inefficacy in solution.
Body surface static in solution is easily adhered to by solute crystallization or impurity, as makes constantly move among a small circle solute crystallization or impurity of object in solution just be difficult for adhering to, thereby reaches the object that prevents that detecting electrode lost efficacy.Because solute in solution is different with impurity, thus different to the frequency requirement of motion, so need to changing within the specific limits, the frequency of motion could be applicable to various solution.In addition,, if the motion of object is unidirectional, the normal direction part of the direction of motion is still easily adhered to by solute crystallization or impurity.Therefore, need alternately can reach just now at certain frequency scope variant-frequency vibration the object that prevents inefficacy in two orthogonal directions.
The technical scheme that technical solution problem of the present invention adopts is as follows:
Prevent the device that in solution, detecting electrode lost efficacy, comprise detecting electrode cover, guiding gutter, X axis vibration device, Y axis vibration device and central Frequency Drive Control device.
Detecting electrode cover is used for placing detecting electrode, and it is connected with detecting electrode close mechanical, guarantees that detecting electrode normally works in solution simultaneously.
Central authorities' frequency-variable controller, has independent binary channels VFC driving force, can export individually or simultaneously control, and has the function of connection or the electrical connection of disconnection detection electrode.
X axis vibration device and Y axis vibration device are mutually orthogonal.X axis vibration device is the vibrator being fixed in detecting electrode cover X-direction, and the vibration of directions X can be provided under the control of central frequency-variable controller.Y axis vibration device is the vibrator being fixed in detecting electrode cover Y direction, and the vibration of Y-direction can be provided under the control of central frequency-variable controller.
Guiding gutter is for ensureing the natural fluidity of solution, to guarantee the timely and accurate of testing result.
Further feature, is provided with detecting electrode adapter, and the detecting electrode that detecting electrode adapter can adaptive different-diameter can be fixed detecting electrode and electrode sleeve better not affecting detect performance in the situation that.
The present invention can effectively avoid detecting electrode in solution to lose due measurement function because solute crystallization or impurity adhere to, can be widely used in the industry fields such as metallurgy, chemical industry, biologic product, pharmacy and aquatic products, simple in structure, practical, reliability is high.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is electrode adapter structural representation of the present invention.
In figure: 1 hook; 2 detecting electrode covers; 3 electrode adapter; 4 central frequency-variable controllers; 5 X axis vibration devices; 6 Y axis vibration devices; 7 guiding gutters.
Detailed description of the invention
Detecting electrode is inserted in detecting electrode cover 2, regulate electrode adapter 3 to make detecting electrode and detecting electrode overlap tight mechanical connection.Hang in solution whole by linking up with 1, treat the guiding gutter solution that submerges.Central authorities' frequency-changing control system 4 starts X axis vibration device 5, Y axis vibration device 6 in turn or simultaneously according to certain time interval, and regulates vibration frequency according to certain time interval.Central authorities' frequency-changing control system 4 is connected and controls with X axis vibration device 5, Y axis vibration device 6 by soft high temperature resistant wire.Because detecting electrode cover 2 and detecting electrode are by X axis vibration device 5, the related generation once per revolution vibration of Y axis vibration device 6, therefore effectively avoid solute crystallization or impurity in the adhering to of detecting electrode, thereby reached the effect that prevents that detecting electrode lost efficacy.Guiding gutter 7 flows for solution, timely and accurate with what guarantee to measure.
Because detecting electrode can affect accuracy of detection during vibrating, so central frequency-changing control system 4 is automatically closed detecting electrode in the time starting X axis vibration device 5, Y axis vibration device 6, in the time stopping X axis vibration device 5, Y axis vibration device 6, recover detecting electrode work.
