Background technology

At present sugar industry detects syrup density on producing, and promptly the mode of degree of hammer into shape has two kinds, a kind ofly detects for traditional artificial glass concentration meter; This detection mode hand labor intensity is big, is difficult to frequent detection.Another kind of for utilizing the characteristic that signal can weaken behind the syrup in the gamma rays piping, along with the different principle of the unlike signal attenuation degree of syrup concentration detects.This pick-up unit has the defective of several aspects: 1, belong to radioactive product, human body is had certain injury; When 2, detecting, if pipeline syrup instability of flow or syrup bubble are more, testing result is untrue; 3, sensing range is narrow, can only detect point of terminal steam tank at present.

Summary of the invention

The purpose of this utility model provides a kind of syrup hammer degree on-line automatic detection device, and it should be able to conveniently detect, and reduces labour intensity, and is harmless, and, the wide and precision height of sensing range.

The utility model comprises control box and the computing machine that several syrup evaporator hammer degree of control detect, and connects with importing/go out pipeline between each evaporator, it is characterized in that also comprising:

Feed pipe communicates with described evaporator efferent duct, contain bucket type weigh container and run-down pipe and vent pipe, and the constant volume weighing apparatus of LOAD CELLS, wherein, feed pipe and run-down pipe communicate with it in the upper end of the container of weighing, and are provided with the control of controlled case of solenoid valve and computing machine in feed pipe and the vent pipe;

Constant volume weighing apparatus of configuration on the output channel of each evaporator.

The syrup hammer degree on-line automatic detection device of said structure, the container of weighing in the constant volume weighing apparatus is known volume, open the electromagnetic valve on the feed pipe, add syrup, syrup is discharged by run-down pipe after being full of the container of weighing, and closes inlet valve, allows extra syrup be continued to discharge by run-down pipe, until the capacity of setting, assert that promptly the syrup volume in the container of weighing is known volume; Measure syrup weight signal in this container by the LOAD CELLS that interrelates with the container of weighing, this weight signal is passed to control box, through signal amplification, A/D conversion of signals, send data-signal to computing machine again, carry out data analysis by computing machine and handle, contrast corresponding syrup standard, on display, demonstrate the syrup hammer degree of being surveyed, the hammer degree is the professional term of sugar industry, and the density of expression syrup is represented with BX, below continues to use.The advantage of this device is: 1, can measure syrup density 5～80BX, syrup density general range is 20～80BX, and measurement range is wide; 2, measuring accuracy height, nominal error are ± 0.2BX that production requirement is ± 0.5BX; Measuring speed is fast, measures once, and satisfies production requirement far away in per 3 minutes; 3, be not subjected to pipeline syrup flow size and the contained influence of air bubbles of syrup; 4, but a cover pick-up unit multiple spot detects, and forms a monitoring system, can be the further full-automatic computer supervisory control system of a whole set of syrup evaporation and concentration of exploitation of basis according to this, realizes automated production management, replaces traditional manually-operated production at present.
