Description

Technical Field

[0001] This utility model relates to the technical field of floating roof oil recovery devices, and in particular to a fully liquid-contact dual-disc floating roof oil recovery device with oil layer monitoring. Background Technology

[0002] Oxygen-barrier floating roof oil collection devices are widely used in wastewater tanks, settling tanks, and oil removal tanks in oil fields and petrochemical industries. The floating roof moves up and down with the change of liquid level in the tank, and at the same time, it can isolate the liquid in the tank from the air. The oil collection device is installed at the bottom of the floating roof and moves with the floating roof. The observation results determine whether it is necessary to absorb the floating oil. The oil collection port position of the existing floating roof oil collection device is fixed and cannot be adjusted by itself, so the oil collection range is relatively small, resulting in low oil collection efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a floating disc oil recovery device with full liquid contact and dual discs and oil layer monitoring in order to solve the above problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fully liquid-contact, dual-disc floating-plate oil recovery device with oil layer monitoring includes a tank body. A floating plate is installed inside the tank body. Multiple floats are evenly distributed at the bottom of the floating plate. A sealing strip is provided around the outer edge of the floating plate. A first rotating shaft is rotatably connected to the floating plate. A transmission disc is installed at the bottom of the first rotating shaft. Multiple strip-shaped holes are evenly distributed on the transmission disc. A second liquid delivery rod is installed within each strip-shaped hole. A liquid delivery cylinder is installed on the transmission disc. One end of the second liquid delivery rod has an oil recovery port, and the other end of the second liquid delivery rod is connected to the liquid delivery cylinder. An oil pump is installed outside the tank body. The input end of the oil pump is connected to the first liquid delivery rod. One end of the first liquid delivery rod is connected to a liquid delivery pipe, and one end of the liquid delivery pipe is connected to the liquid delivery cylinder. The liquid delivery pipe and the liquid delivery cylinder are rotatably connected via bearings. A transmission mechanism for controlling the rotation of the transmission disc is provided on the floating plate. An oil layer monitoring mechanism is installed inside the tank body.

[0006] Preferably, the transmission mechanism includes a gear disposed on the top of the first rotating shaft, a telescopic cylinder disposed on the floating plate, and a toothed plate disposed on the output end of the telescopic cylinder, the toothed plate and the gear being meshed together.

[0007] Preferably, a plurality of transmission rods are evenly distributed on the top of the first rotating shaft, and the ends of the transmission rods are provided with scrapers that abut against the inner wall of the tank.

[0008] Preferably, a positioning seat is provided on the upper surface of the floating disk, and the first rotating shaft passes through the positioning seat, and the first rotating shaft and the positioning seat are rotatably connected.

[0009] Preferably, the oil layer monitoring mechanism includes an oil-water interface analyzer disposed at the bottom of the floating roof, and a controller is disposed on the outside of the tank body. The controller and the oil-water interface analyzer are electrically connected via data wires.

[0010] Preferably, a first limiting seat is provided on the top of the tank, a first guide roller is rotatably connected to the first limiting seat, a positioning plate is provided on the side of the tank, two second limiting seats are symmetrically arranged on the side of the positioning plate, a second guide roller is rotatably connected to the second limiting seat, and a telescopic component for retracting and extending the data cable is provided on the inner side of the two second guide rollers.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] 1. Compared with the prior art, this application adds an oil-water interface analyzer to the floating roof. The oil-water interface analyzer transmits the monitored information to the controller through data wires. Then, the staff determines whether to start the oil pump to extract the floating oil based on the information. Compared with the existing floating roof oil recovery device, the acquisition of oil layer information is simpler and faster, making the monitoring and extraction of oil layer simpler and improving work efficiency.

[0014] 2. This application includes a telescopic cylinder. The telescopic cylinder drives the first rotating shaft to reciprocate through the cooperation of the toothed plate and gears. The first rotating shaft simultaneously drives the transmission disc and scraper to reciprocate. The scraper can clean the inner wall of the tank to prevent dirt from adhering to the inner wall. The transmission disc drives the oil collection port to rotate, which increases the range of motion of the oil collection port and improves the oil collection efficiency. Attached Figure Description
