Abstract
The utility model discloses a device for measuring the liquid level of the oil water in an oilcan, which is characterized in that two level meters which are a radar level meter and a radio frequency transadmittance level meter are installed on the oilcan, a radar level gage (1) is connected with a wave guide pipe (2) by a flange (3), and the wave guide pipe (2) is welded on the top of the oilcan; the lower end of the wave guide pipe (2) is level with the horizontal center line of an offlet (12); a radio frequency transadmittance level gage is connected with the top of the oilcan by a connector, and the height of the lower head end of the radio frequency transadmittance level gage is lower than the offlet. The device can measure the oil level and the water level in the oilcan at the right time, discharge the water and supplement the oil in time, ensure the production to run normally, save energy, reduce the output of waste gas and reasonably plan the production and purchase according to the measured oil level; meanwhile, the labor intensity is lightened.
Description
Technical field
The utility model relates to a kind of oil tank oil-water fluid level measuring arrangement.
Background technology
In aluminium oxide and the plain production run of charcoal, need to use the oil tank oil storage.Owing to contain moisture content in the oil, to accumulate over a long period, therefore oil and water separation, water sedimentation, regularly discharge water by the ajutage of oil tank bottom in the bottom, simultaneously, know oil level again in real time, so that in time replenish new light oil.But, in use in the past, also do not have measurement mechanism that light oil jar profit liquid level is measured.
How is the profit liquid level measured? through research, we have just proposed employing interface level measurement and level gauging, and the difference of the two equals the mode of oil level, solve this section's topic.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of oil tank oil-water fluid level measuring arrangement is provided, with remedy that prior art exists to the immeasurable deficiency of light oil jar profit liquid level.
The technical scheme that the utility model is taked is: two level meters are installed on the light oil jar, the one, radar levelmeter is used to measure profit liquid level sum, the 2nd, the radio frequency admittance level meter is used to measure the liquid level of the following water of water-oil interface, the two signal is sent into secondary table or PLC carry out subtraction and handle, demonstrate oil level in real time.
Measuring principle is: the radar level gauge 1 on light oil jar top is connected with waveguide pipe 2 usefulness flanges 3, and the lower end of waveguide pipe is the ajutage center line, and fixing with angle steel 8, and waveguide pipe is welded on the oil tank top, this covering device be used to measure oil and water liquid level with.Radio frequency admittance level-sensing device 9 on light oil jar top, its lower end is lower than ajutage 50mm, the radio frequency admittance level-sensing device is connected with oil tank with joint 10, and joint is welded on the oil tank top, because the specific inductive capacity of oil is 25, the specific inductive capacity of water is 87, radio frequency admittance level-sensing device measuring principle is measured changes in capacitance, therefore exactly, the radio frequency admittance level-sensing device is easy to realize that the electric capacity with oil masks, and measures the liquid level of water outlet.Obviously, the liquid level that both measure poor is exactly oil level.
The meaning of oil tank profit level gauging is as follows:
If accident gauging pot bottom water level, profit is beaten the user by oil pump and is burnt, and moisture content burning will consumption of calorie, therefore, measures water level, in time bleeds off, and energy-saving and emission-reduction are played a positive role.
Owing to there has been the oil tank oil level to show, factory department's scheduling can rationally be arranged the workman to operate and in time buy light oil and go into factory.
Because the tank bottom water level has been arranged, the operator in time discharges water according to water level, reduces labor strength.
Therefore, compared with prior art, the utility model can be measured oil level and the water level in the oil tank in good time, in time bleeds off water and makeup oil, guarantee to produce normal operation, energy savings reduces the discharge rate of waste gas, measuring oil level can rationally arrange production and buy, and simultaneously, reduces labour intensity.
Description of drawings
Fig. 1 installs the radar level gauge structural representation for oil tank;
Fig. 2 installs radio frequency admittance level-sensing device synoptic diagram for oil tank;
Embodiment
The embodiment of this utility model: as shown in Figure 1, on light oil jar top, radar level gauge 1 is installed, radar level gauge 1 is connected by flange 3 usefulness bolts 5, nut 6 and packing ring 7 with waveguide pipe 2, and pad 4 is arranged between two flanges 3; The part that waveguide pipe 2 is goed deep in the oil tank has air hole 11, and the diameter of air hole is 6mm, and the effect of air hole mainly is to make the gas in the waveguide pipe logical with the gas phase in the oil tank, and air pressure is identical, and is consistent with liquid level in the oil tank with the liquid level in the assurance waveguide pipe.The lower end of waveguide pipe 2 is concordant with the horizontal center line of ajutage 12, and fixing with angle steel 8, the horizontal center line of ajutage 12 apart from oil tank at the bottom of 150mm, waveguide pipe 2 is welded on the oil tank top; This covering device is used to measure the liquid level sum of oil and water.As shown in Figure 2, on light oil jar top, radio frequency admittance level-sensing device 9 is installed, its lower end is lower than ajutage, apart from 50mm at the bottom of the oil tank; The radio frequency admittance level-sensing device is used joint 10 and is connected, joint is welded on the oil tank top, because the specific inductive capacity of oil is 25, the specific inductive capacity of water is 87, radio frequency admittance level-sensing device measuring principle is measured changes in capacitance, therefore exactly, the radio frequency admittance level-sensing device is easy to realize that the electric capacity with oil masks, and measures the liquid level of water outlet.Obviously, the liquid level among Fig. 1 and Fig. 2 poor, the oil of measuring with radar level gauge and the liquid level sum of water deduct the water level of measuring with the radio frequency admittance level-sensing device exactly, and it is exactly an oil level.
