Utility model content
For the deficiency that prior art exists, the purpose of this utility model is a kind of mixing plant providing a kind of quantitative liquid feeding humidification when humidity is too low.
For achieving the above object, the utility model provides following technical scheme: a kind of from humidification concrete mixing plant, comprise stirring host, described stirring host is provided with inlet opening, carries out liquid feeding by arranging feed tube on inlet opening; Described mixer inside is also provided with humidity sensor, described humidity sensor is for detecting stirring host interior humidity and exporting a sampled voltage, described humidity sensor is coupled to humidity measuring circuit, and described humidity measuring circuit comprises base modules, provides a reference voltage; Comparison module, is coupled to base modules and humidity sensor, when sampled voltage is lower than comparative voltage, exports humidification signal; Time delay module, is all connected to the output of comparison module, when receiving humidification signal, exports the drive level that continues the very first time; Also be provided with magnetic valve between described feed tube and described inlet opening, described magnetic valve is controlled by drive level and opens.
First, when humidity is too low, the sampled voltage that humidity sensor response exports reduces, until lower than reference voltage, comparison module can export humidification signal, and time delay module receives this signal, and Controlling solenoid valve opens certain hour, the concrete opening time can be regulated by the drive level duration of time delay module, and magnetic valve is opened and be ensure that output.
Further: base modules comprises the first divider resistance, the second divider resistance and the 3rd divider resistance that are arranged in series, and the node that described first divider resistance and the second divider resistance couple provides reference voltage.Arranged by three electric resistance partial pressures, reference voltage zero passage can be prevented, and reference voltage obtains by this way more stable.
Further: described 3rd divider resistance is set to adjustable resistance.By the setting of the 3rd resistance, to a reference value of humidity, can regulate according to the actual requirements.
Further: described comparison module is configured to comparator.By the setting of comparator, response speed is very fast, ensure that the precision of humidity regulation.
Further: described time delay module comprises the delay capacitor and discharge resistance that are arranged in parallel, one end of described delay capacitor is also coupled to the output of NPN pipe.By regulating the resistance of discharge resistance just delay time can be regulated, thus regulate the amount adding liquid.
By adopting technique scheme, function in this scheme of normal condition can not produce any impact to whole production technology, if but due to environment is too dry or due to the carelessness of operation indoor occupant cause not carrying out for a long time stirring or interior humidity too low, so when humidity is too low, in order to prevent the generation of just junction phenomena, so arrange a humidification module, when the humidity in cylindrical shell reaches the range of needs of just knot, open with regard to Controlling solenoid valve, add quantitative liquid, with time inner and humidity of materials rising, ensure that humidity is in safety value.
