Fig. 1 is the planar structure synoptic diagram of this container, reactor liquid level gauge device.
Among the figure, 1, tank body; 1a, interface; 2, plemum pressure guiding pipe; 3, negative pressure chamber's pressure guiding pipe; 4, differential pressure measurement mechanism; 5, pressure-sensitive bellows; 6, protection tube; 7, paddle.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, this container, reactor liquid level gauge device comprise the tank body 1 with material-holding chamber, and the top of tank body 1 offers several interfaces 1a, and tank body 1 top is provided with by the pressure reduction liquid level gauge in interface 1a insertion tank body 1 material-holding chamber.
The pressure reduction liquid level gauge has a plemum pressure guiding pipe 2 and negative pressure chamber's pressure guiding pipe 3, all be full of silicone oil in plemum pressure guiding pipe 2 and the negative pressure chamber's pressure guiding pipe 3, the lower end of plemum pressure guiding pipe 2 and negative pressure chamber's pressure guiding pipe 3 is provided with pressure-sensitive bellows 5, the bottom of pressure-sensitive bellows 5 has diaphragm, and a side of this pressure-sensitive bellows 5 contacts with silicone oil.Be connected with the differential pressure measurement mechanism 4 that can measure pressure reduction between the two pressure chambers between plemum pressure guiding pipe 2 and the negative pressure chamber's pressure guiding pipe 3 by electrical signal conversion.
Tank body 1 has body and top cover, and interface 1a is opened on the top cover, and top seal is installed in bodies top, and stores the liquid material that certain liquid level is arranged in the material-holding chamber of body.The periphery of plemum pressure guiding pipe 2 is arranged with a protection tube 6, the steel pipe of protection tube 6 for having certain rigidity, its upper end is welded with flange one, be installed with flange two on the tank body 1 interface 1a, protection tube 6 upper ends align interface 1a and cross bolt by flange one and flange two-way and are connected, protection tube 6 lower ends and pressure-sensitive bellows 5 weld together, and the bottom of pressure-sensitive bellows 5 is diaphragms; Be connected flange and directly being connected with another interface 1a of negative pressure chamber's pressure guiding pipe 3 ends, negative pressure chamber's pressure guiding pipe 3 ends are provided with pressure-sensitive bellows 5.Plemum pressure guiding pipe 2 stretches into the height and position place that the following somewhere of liquid level need be measured, if also be provided with paddle 7 in some reactors that need stir material, this moment, plemum pressure guiding pipe 2 lower end was in about 5 centimeters in paddle 7 tops in the liquid material.Plemum pressure guiding pipe 2 is stretched out the corresponding connection of plemum of the differential pressure transmitter that is had with differential pressure measurement mechanism 4 by interface 1a; Negative pressure chamber's pressure guiding pipe is the same with conventional two flange fluid level transmitters to be installed on the interface 1a of top cover, measure gaseous pressure in the still, fluid level transmitter carries out negative transfer earlier, like this, stirs when static, the pressure reduction of the positive negative pressure chamber of transmitter equals liquid level and multiply by medium proportion, yet when stirring the operation back, the liquid level that transmitter shows can change, and changing value depends on stirring intensity, but the liquid level change time difference value is constant substantially, and this experience difference needs to sum up by the liquid level gauge actual motion.This liquid level gauge is suitable for level gauging rather than metering.
During the measuring liquid level height, the pressure action of liquid or gas is on the diaphragm of the pressure-sensitive bellows 5 of this position, so silicone oil that the diaphragm of pressure-sensitive bellows 5 compressing pressure-sensitive bellows 5 is contacted, and by silicone oil pressure intensity is passed to differential pressure measurement mechanism 4 and compares the pressure reduction that calculates between the two, then pressure reduction is converted to 4-20maDC normalized current signal, thereby realizes the measurement of liquid level.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used tank body 1 morely; Interface 1a; Plemum pressure guiding pipe 2; Negative pressure chamber's pressure guiding pipe 3; Differential pressure measurement mechanism 4; Pressure-sensitive bellows 5; Protection tube 6; Paddle 7 terms such as grade, but do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
