Description

Technical Field

[0001] This utility model relates to a monitoring device, and more particularly to an online monitoring and metering device for marine oil spill. Background Technology

[0002] Marine oil sludge contains waste water-containing fuel oil, engine oil, lubricating oil, etc. If this sludge is discharged directly without effective treatment, it will cause serious damage to the marine, river, and lake ecosystems. However, because marine oil sludge has certain utilization value, it has attracted many service companies to participate in its recycling and treatment. In this process, the metering and testing of oil sludge is crucial.

[0003] Traditional methods for measuring and testing marine oil sludge have numerous problems. In testing the water content of oil sludge, manual gauging or sampling is often used. However, the sampling method and gauging location are susceptible to human error, making scientific monitoring difficult and significantly compromising the accuracy and reliability of the test results. For example, different sampling personnel may choose different sampling locations and sample sizes due to varying operating habits, leading to deviations in the measured water content of the oil sludge, which in turn affects the quality and price determination of the oil sludge in the market.

[0004] Shipping companies face enormous cost pressures. Under these circumstances, how to scientifically test and measure marine oil spills and ensure fair and just settlement between the two parties has become an urgent problem for shipping companies to solve. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an online monitoring and metering device for ship oil spill that has stable and accurate detection signals.

[0006] The technical solution of this utility model is as follows: A ship oil sludge online monitoring and metering device includes a cabinet, characterized in that: a detection pipe is provided inside the cabinet, the detection pipe is approximately Z-shaped and has an inlet and an outlet respectively leading out from both sides of the cabinet, the inlet is located at the lower part of one side of the cabinet and the outlet is located at the upper part of the other side of the cabinet, and a mass flow meter and a water content analyzer are installed sequentially on the vertical section of the detection pipe inside the cabinet, which are used to detect the mass of oil sludge passing through the metering device per unit time; The moisture analyzer includes an outer protective tube. A meter head is connected to one side of the outer protective tube via a connecting pipe. The inner hole of the outer protective tube is stepped. Two symmetrically arranged and separated arc-shaped probes are installed in the middle of the outer protective tube via an insulating sleeve. One probe has a connecting rod connected to its outer edge. The connecting rod passes through the connecting pipe and is electrically connected to a primary meter located in the meter head for transmitting detection signals. The other probe is fixed inside the outer protective tube by screws for synchronously receiving detection signals. A sealing cap is threaded to one end of the larger hole in the inner hole of the outer protective tube to press the two probes together.

[0007] As a further preferred option, connecting flanges are welded to one end of the inlet and one end of the testing pipeline to facilitate installation.

[0008] As a further preferred option, the mass flow meter is a straight-tube mass flow meter.

[0009] As a further preferred option, an explosion-proof box is provided inside the cabinet, and a PLC and a wireless transmission module are installed inside the explosion-proof box. The signal output terminals of the mass flow meter and the moisture content analyzer are electrically connected to the PLC installed inside the explosion-proof box, respectively, for receiving data from the mass flow meter and the moisture content analyzer and uploading it to the server through the wireless transmission module.

[0010] As a further preferred option, an audible and visual alarm is installed on one side of the cabinet. The control terminal of the PLC is connected to the audible and visual alarm to prompt the crew members receiving oil to switch between the oil receiving tank and the sewage tank.

[0011] As a further preferred option, a base is bolted to the bottom of the cabinet. The base is a rectangular frame welded from channel steel, which is convenient for welding and fixing to the hull.

[0012] The beneficial effects of this utility model are: 1. The water content analyzer has two symmetrically arranged arc-shaped probes in the middle of the outer protective tube. One probe passes through the connecting tube via a connecting rod and is electrically connected to the primary meter inside the meter head to transmit detection signals. The other probe is fixed inside the outer protective tube with screws to receive detection signals synchronously. This not only ensures that the medium to be tested flows through the detection point without obstruction, but also makes the detection signal more stable by symmetrically arranging the probes, further improving the detection accuracy.

[0013] 2. Because the detection pipeline is approximately Z-shaped with the inlet located at the lower part of one side of the cabinet and the outlet located at the upper part of the other side of the cabinet, the ship's sludge oil can enter the detection pipeline under the power of the oil pump and fill the Z-shaped detection pipeline without air entering, which can ensure high accuracy of the detection data.
