According to the oil storage tank monitoring device, the vertical pipe with the upper end connected to the monitoring port and with the lower end penetrated into the tank body is further arranged on the monitoring port of the tank body, the transmitter is arranged in the vertical pipe, thus the gas collection barrel and the capillary tubes can be prevented from being impacted and are not easy to bend and damage, and the service life of the oil storage tank monitoring device is prolonged; the filter screen is arranged on the opening in the side face of the vertical pipe, so a pressure inlet of the gas collection barrel is not easy to block, and measurement precision of the gas collection barrel can be maintained for a long time.
Description
Technical field
The utility model relates to a kind of petrol storage tank, relates in particular to a kind of monitoring device of petrol storage tank.
Background technology
The liquid level of petrol storage tank is the important parameter in the process of oil production, and monitoring liquid level exactly has very important meaning to automation and the safety in production of process of oil production.Liquid level meeting out of control makes crude oil overflow, lead to great industrial accident and problem of environmental pollution.
Domestic and international level gauging to petrol storage tank does not also have good solution at present.Many places mainly adopt the method for hand dipping that liquid level is carried out periodic monitor, the workman climbs up oil tank high more than 6 meters, the metric system steel band tape measure that has weight or the scale that has a scale are knocked down oil tank, and the hand-kept reading just can obtain the oil mass data through complicated calculation.This method of measurement workman needs in the open air the measurement of climbing under the great environment of the height temperature difference, poor stability, labour intensity are big, not only very inaccurate, and can not carry out timing monitoring, cause loss and the waste of crude oil easily, this method is progressively eliminated.Equal pressure epithelium liquidometer or mechanical type float level meter are adopted in the place that also has, but because epithelium formula temperature influence is big, and have the gas leakage problem; Mechanical type float level meter mechanical driving part complexity, maintenance is difficulty relatively, often occurs mechanical breakdowns such as steel band is stuck, drive disk assembly wearing and tearing again, brings very big inconvenience to use; Existing radar level gauge, ultrasonic level gage are vulnerable to the influence of environment.
Owing to still there not being at present ripe product aspect the petrol storage tank level gauging, all researching and developing both at home and abroad.The fertile day Science and Technology Ltd. in Nanjing has produced a kind of gas collection bucket formula fluid level transmitter, principle is the air in the fluid to be measured medium compression gas collection bucket, air pressure passes to end instr by capillary tub, end instr itself does not directly contact with measured medium, therefore transmitter can be applied in the media environment of higher temperature, simultaneously, and the miniature signal processing circuit that it is built-in, can directly be connected with computer interface card, control instrument, intelligence instrument or PLC etc., carry out remote transmission.This transmitter mainly is made up of housing, treatment circuit, gas collection bucket, capillary tub etc., during installation, adopt structures such as interface thread or flange and tank body to join, gas collection bucket input in liquid, cable leads to display instrument or is connected with control system from housing internal wiring terminal.Existing occupation mode is directly housing to be connected on the tank body, capillary tub, gas collection bucket are suspended in the tank body, when refueling in from the upper end of tank body to tank body, can produce very big impact to capillary tub and gas collection bucket, gas collection bucket and capillary tub be swayed repeatedly, because capillary tub is thinner, bending, bump etc. repeatedly, therefore easily make its damage, gas collection bucket entrance pressure mouth easily blocks in addition, influences survey precision.
Summary of the invention
The purpose of this utility model is to provide a kind of long service life, simple in structure, the easy permanent petrol storage tank monitoring device that keeps survey precision.
The technical scheme that the utility model adopts for achieving the above object is:
A kind of petrol storage tank monitoring device, comprise tank body and fluid level transmitter, the upper end of described tank body is provided with oil inlet, the bottom is provided with oil outlet, the upper end of described tank body also is provided with monitoring mouthful, and described fluid level transmitter is arranged in the monitoring mouthful, it is characterized in that: also be provided with the upper end in the described monitoring mouthful and be connected in monitoring mouthful upper and lower end and go deep into standpipe in the tank body, the side of standpipe is provided with opening, and described fluid level transmitter is arranged in this standpipe.
In order to prevent that gas collection bucket entrance pressure mouth from blocking, improve survey precision, riser bottom described in the utility model stretches to tank base, the base seal of standpipe, the opening of standpipe side is provided with filtering net.
The utility model also is provided with the upper end and is connected in monitoring mouthful upper and lower end and gos deep into standpipe in the tank body on the monitoring mouth of tank body, transmitter is arranged in this standpipe, can make gas collection bucket and capillary tub avoid impacting, and is difficult for bending and damages, and improves its service life; Opening in the standpipe side arranges filtering net, and the entrance pressure mouth of gas collection bucket is difficult for blocking, and its survey precision for a long time can preserve value.Compared with prior art, the beneficial effect of its enforcement is apparent.
