Abstract
An intelligent electrode heating technique automatically adjusts the electric parameters (or the distance between electrodes, or the effective area of electrode, or the media between the electrode) of two ends of electrode being heated to realize the automatic adjusting of electric power for obtaining the optimum heating result by set up control circuit of power automatic adjustment according to the characteristics of that the conductivity of the article being heated will be changed along with the changes of solution temperature and solution concentration.
Description
One, technical field
The invention belongs to the electric-heating technology field.
Two, background technology
Traditional heating means normally by three kinds of modes such as convection current, radiation, conduction, are carried out thermal energy transfer to heating object, reach the purpose of heating.This heating means are when carrying out thermal energy transfer, also surrounding environment is carried out thermal energy transfer, heating object after being heated also will carry out thermal energy transfer to environment on every side, and heated body surface is heated to inside and is heated and needs the regular hour, time is long more, the loss of heat energy is just big more, and the heat efficiency is also just low more.Therefore, traditional mode of heating is a kind of heating means of poor efficiency.The heated by electrodes method is a kind of new heating means that grew up in recent years.This method is with in the heated liquid of the direct insertion of the electrode of single-phase or three phase mains, directly liquid is heated, this heating means are for traditional heating means, have plurality of advantages such as heating means are simple, firing rate is fast, efficient height, but in putting into practice use, existing following shortcoming: 1). the electric conductivity of heating object changes with the variation of temperature, solution concentration, after solvent and solute heating, solution concentration changes, cause the variation of electric conductivity, can cause the problem of potential safety hazard; 2). the electrochemical reaction of electrode material in solution heating process, not only influence life-span of electrode, to being heated solution corrosiveness is arranged simultaneously.Because the problems referred to above can not get solving, so electrode heating technology has just lost its practical value to a great extent.
Three, summary of the invention
The objective of the invention is to be intended to overcome above-mentioned shortcoming, a kind of intelligent electrode heating technology is provided.
Main points of the present invention are: the characteristics that change with the variation of solution temperature, solution concentration according to the conductivity of heating object, automatically adjust control circuit by set power, electrical quantity (or distance between electrodes to the electrode two ends, or the effective area of electrode, or the medium between the electrode) automatically adjusts, reach automatic adjustment to electrical power, reaching best heats, and stop in the heating process problem that changes and cause that electric conductivity changes and safety is caused a hidden trouble owing to solvent and solute; Meanwhile, by improving the material of heating electrode, to prevent the problem of electrode self generation electrochemical reaction in the heating process.
The present invention through after the above-mentioned design compared with prior art has the following advantages:
1, usage range is wide, can be applicable in the every field in industry, agricultural, national defence, the domestic life heating to various liquid and solid;
2, heat efficiency height, energy-saving effect are remarkable; In plastic containers, adopt intelligent electrode heating technology that 1 kilogram same solution is heated to 100 ℃ of electric energy that consumed and only be 1/2nd of common electric energy heater institute consumed power;
3, in heating process, hot coherence is little, can realize high-precision temperature control;
4, have disconnected liquid and stop heating function automatically.

Five, embodiment
The intelligent electrode heating technology characteristics that to be a kind of conductivity according to heating object change with the variation of solution temperature, solution concentration, automatically adjust control circuit by set power, electrical quantity (or distance between electrodes to the heating electrode two ends, or the effective area of electrode, or the medium between the electrode) automatically adjusts, reach electrical power is carried out self-adjusting purpose, to reach the heated by electrodes new technology of best heats.It comprises that heating electrode, heating container and power adjusts the control circuit three parts automatically.Heating electrode 1., 2. insert heating container 3. in, heated liquid is directly contained in the heating container, adjusts control circuit automatically by power and controls automatically, and it is directly heated.
Power is adjusted control circuit automatically and is included controllable execution circuit, signal sampling circuit, current rectifying and wave filtering circuit, forward amplifying circuit, the drive circuit that normal open uses, simultaneously, also be provided with n voltage comparator, (n-1) individual square-wave generator, inverter, (n-1) individual trigger and (n+1) individual and door and n NOR gate circuit.
In order to solve electrode, select for use platinum, graphite, carbon as electrode material in heating process generation electrochemical reaction; Or the frequency of the alternating current by improving the electrode two ends, avoid electrode material that electrochemical reaction takes place in heating process.
For ease of further understanding the present invention, the operation principle of the present invention and the course of work are elaborated below in conjunction with accompanying drawing:
