Abstract
The utility model discloses a device for measuring the pulp level in a pulse buffer tank. The device adopts the structure that a radioactive source mounting bracket (1) is arranged on one side of a pulse buffer tank (3), and a radioactive source (4) for a gamma ray liquid level gauge (4) is installed on the radioactive source mounting bracket (1); detector mounting brackets (2) are arranged on the other side of the pulse buffer tank (3), and a detector (5) for the gamma ray liquid level gauge is installed on the radioactive source mounting bracket (1); and the number of the detector mounting brackets (2) is four, i.e., two upper detector mounting brackets and two lower detector mounting brackets. Since two Cs-137 radioactive sources are reduced, the cost of the device can be reduced by 30 percent, the environmental protection management cost and the future waste source treatment cost are both reduced, meanwhile, the adverse effects to the personal safety of the maintenance staff on the spot are decreased, and the device is beneficial to the environmental protection and the sustainable development for production of alumina in China.
Description
Technical field
The utility model relates to mineral pulp level measurement mechanism in the pulse buffer jar of a kind of aluminium oxide bayer process high pressure stripping workshop section.
Background technology
From domestic and international alumina producing enterprise, mineral pulp level is measured the design of always continuing to use French Bi Sinie company in the pulse buffer jar of aluminium oxide bayer process high pressure stripping workshop section, and promptly high limit, high limit, the lower bound of mineral pulp level measured by 3 gamma ray level switches respectively in the pulse buffer jar.3 Cs-137 radioactive sources of this each jar of design needs and corresponding supporting 3 detectors and 3 converters.As shown in Figure 1.This design has continued nearly 20 years.Because radioactive source is many, unfavorable to the maintainer's at scene health of human body, big to the management and the disposal cost of useless source of environmental protection.
Summary of the invention
The technical problems to be solved in the utility model is, mineral pulp level measurement mechanism in a kind of pulse buffer jar is provided, many to overcome the radioactive source that prior art exists, unfavorable to the maintainer's at scene health of human body, big etc. not enough to the management of environmental protection and the disposal cost of useless source.
The utility model is taked following technical scheme: source mounting bracket 1 is penetrated in the side setting at pulse buffer jar 3, at the opposite side of pulse buffer jar 3 detector mounting bracket 2 is set.
The quantity of detector mounting bracket 2 amounts to 4, each 2 up and down, is used to install the detector of 2 gamma ray liquid level gauges.
Measuring principle: gamma ray instrument work principle is, ray is penetrated in the source of penetrating, and detector sends pulse after detecting the ray that passes measured medium, and the statistics pulse is after the converter calibrated and calculated draws the height of wanting measuring liquid level.
The utility model is satisfying under the condition of technological requirement, uses the little radioactive source of activity as far as possible, to guarantee personal security, reduces expenses of environmental protection.Make 3 original gamma ray level switch measurement amounts into one and penetrate the continuous quantity measurement that the source adds a pair of redundancy, this each jar of design only needs 1 Cs-137 radioactive source and corresponding supporting 2 detectors and 2 converters.
During work, detector sends pulse after detecting the ray that passes measured medium, add up pulse after the converter calibrated and calculated draws the height of measuring liquid level, outputting standard 4～20mA signal, the exportable high limit of simultaneous converter, height are limit, lower bound relay tip signal.
Adopt the continuous quantity of a pair of redundancy to measure detector, like this, can export outputting standard 4～20mA signal, exportable again high limit, high limit, lower bound relay tip signal use for process control.
Measure more reliable, guaranteed measurement and process control accurately, in real time, safety.
The utility model is owing to reduced by 2 Cs-137 radioactive sources, cost of equipment can reduce by 30%, and the management of environmental protection and useless source disposal cost have in the future been reduced, simultaneously, minimizing helps the environmental protection and the sustainable development of China's alumina producing to the adverse effect of field maintemance personnel's personal safety.

Embodiment
Embodiment of the present utility model: as shown in Figure 2: connect at a face down bonding of pulse buffer jar 3 and to penetrate source mounting bracket 1, be used to install the radioactive source 4 of gamma ray liquid level gauge, its opposite side welding detector mounting bracket 2 (totally 4 each 2 up and down), be used to install the detector 5 of 2 gamma ray liquid level gauges.Detector sends pulse after detecting the ray that passes measured medium, adds up pulse after the converter calibrated and calculated draws the height of measuring liquid level, outputting standard 4～20mA signal, and the exportable high limit of simultaneous converter, height are limit, lower bound relay tip signal.
