Liquid remote quantitative loading system

Abstract

The invention relates to a liquid remote quantitative loading system. The system comprises an upper support, a remote alignment system, an automatic loading crane pipe, a control box and a metering system, wherein the automatic loading crane pipe, the control box and the metering system are installed on the upper support. A feeler lever touches a tank opening of an oil storage tank, the control box controls a vertical pipe to extend into the tank opening of the oil storage tank and stop moving after an inlet distance is reached, the control box controls an oil pump to start for oil loading, aprotective shell floats along with the liquid level, and when the inner bottom wall of the protective shell triggers a float switch, the control box controls the oil pump to stop. According to the system, the vertical pipe can be quickly aligned with the tank opening of a tank truck, and a float liquid level meter is designed for automatic control over start and stop of the oil pump and liquid level measurement of the tank truck, so that a flow meter or manual control can be replaced, control over start and stop of the oil pump can be achieved, and quantitative control is more accurate. The system can realize on-site unmanned liquid filling and accurate metering, can improve the oil loading operation efficiency, and achieves the purposes of safety, energy conservation and yield increase.

Description

technical field [0001] The invention belongs to the technical field of crane tubes, and in particular relates to a liquid remote quantitative loading system. Background technique [0002] Crane tube is a kind of pipe that can be stretched and moved. It is mostly used for liquid loading and unloading in petroleum and chemical wharves. At present, when transferring thin oil, it is necessary to use tank trucks for oil transfer. , It is necessary to arrange staff to cooperate with the tanker on site. The on-site staff needs to manually drag the crane pipe to align with the tank mouth of the tanker, and then control the crane pipe to descend deep into the tank to start filling the liquid, and pass the flowmeter, The volume of the filled liquid is measured by weighing the tank car before and after loading, and measuring scales. [0003] Manually dragging and aligning the crane tubes is labor-intensive for the staff. At present, the crane tubes are also installed on the power unit...

Problems solved by technology

The laser is used as the distance measuring medium, and the floating reflector is used to solve the problem of liquid refraction when the laser is used for liquid measurement; the reflector drives the slider to slide upwards to realize real-time monitoring of the liquid level. The structure is flexible and simple, and it is easy to maintain; but , since the fluid is usually required to be pressurized when the crane tube is loaded, there will be a large amount of liquid splash in the tank when the liquid is loaded, and the splashed liquid droplets will fall on the reflector, resulting in inaccurate measurement
