Description
Technical Field
The invention belongs to the technical field of grease monitoring, and particularly relates to an online grease color monitoring and controlling system.
Background
For many years, there has been some progress in automating fat and oil determinations, but many disadvantages still remain. The Lovibond colorimetric method has observation effect and standard which are different from person to person, is suitable for laboratory operation, and has the defects of complicated detection process, long time consumption, difficult quantification of detection data and the like, so that the automatic control of the grease processing process is difficult to realize. The existing automatic detection of the color of the grease mostly utilizes an image analysis technology to compare and detect the color, and has the defects of high requirement on equipment, relatively low data processing speed and long reaction time of auxiliary material addition caused by system disturbance. Simultaneously, the addition of auxiliary material in the refined decoloration workshop section of maize grease still relies on manual operation by traditional experience and intuition, mixes two kinds of auxiliary materials in advance in the course of working, carries out the processing of deciding the ratio to the auxiliary material addition, not only causes the large amount of consumption to single auxiliary material like this, still leads to the loss in a large number of neutral oil in the grease, can make the secondary operation of a large amount of greases handle, increases the repeated consumption of water and electricity gas, leads to the processing cost to rise.
In order to solve the technical problems, the invention patent with the application number of CN201410197245.8 provides an on-line monitoring system for the color and luster of grease, and specifically provides the following technical scheme: the utility model provides a grease color and luster on-line monitoring system, includes blender and filter, be equipped with the ration of adding the auxiliary material on the blender and add the device, the blender is used for treating the decoloration grease and carries out the decoloration to grease after will decoloring carries to the filter and filters, be equipped with image detection device behind the filter, carry out image acquisition to the decoloration grease after filtering to image information who will gather sends to the PLC controller, and the PLC controller carries out analysis processes back to image information, and the control ration adds the device ration and adds the auxiliary material. Although the technical scheme solves the technical problems in the prior art to a certain extent, the technical scheme still has the following technical defects:
firstly, the monitoring position of the grease and the cut-in angle of the light irradiation are fixed, so that the actual monitoring result is only directed at the color of the grease at the fixed grease monitoring position and the light irradiation angle, and the color condition of the whole grease layer cannot be comprehensively reflected.
Secondly, no matter whether infrared spectrum is generated by infrared irradiation or ultraviolet spectrum is generated by ultraviolet irradiation, because the frequencies of infrared ray and ultraviolet ray are not fixed values, but are within a certain frequency range, in other words, light rays within the infrared frequency range can be called as infrared rays, light rays within the ultraviolet frequency range can be called as ultraviolet rays, and the infrared spectrum and the ultraviolet spectrum generated by infrared rays with different frequencies or ultraviolet rays are different, in the technical scheme, the corresponding spectrums generated by infrared rays with different frequencies or ultraviolet rays with different frequencies are distinguished and compared, so that the monitoring result is easy to have deviation, and the monitoring accuracy is reduced. This is a disadvantage of the prior art.
