Description

Technical Field

[0001] The invention relates to a waste oil treatment device. Background Art

[0002] The floating production storage and offloading vessel is like an "offshore oil and gas processing plant" that processes the mixture of oil, gas, water, etc. from the oil wells into qualified crude oil or natural gas. The finished crude oil is stored in the cargo oil tanks. When the reserves reach a certain level, it is transported to shuttle tankers through the external transmission system.

[0003] When waste oil is being processed, it needs to be collected centrally to facilitate its treatment. When the waste oil is pumped into the central tank, waste oil will adhere to the inner wall of the oil inlet pipe mouth and is not easy to collect. It will accumulate near the pipe mouth for a long time, gradually reducing the diameter of the pipe mouth, slowing down the speed at which the oil enters the central tank and reducing the waste oil treatment efficiency.

[0016] The beneficial effects of the present invention are:

[0017] 1. The controller starts the power mechanism and heater. The heater heats and softens the waste oil adhered to the inner wall of the oil pipe. The power mechanism drives the scraping mechanism to scrape off the waste oil adhered to the inner wall of the oil pipe. The pushing mechanism pushes the waste oil scraped off the inner wall of the oil pipe into the collection box, thereby preventing the oil pipe from being blocked and improving the oil supply efficiency of the oil pipe. The limiting mechanism can fix the pushing mechanism to prevent the waste oil from falling from the oil pipe port when the scraping mechanism is driven to scrape off the waste oil.

[0018] 2. The motor drives the power gear to rotate through the rotating shaft, the power gear drives the drive gear to rotate, and the drive gear drives the scraper rod to rotate. The scraper rod scrapes off the waste oil adhering to the inner wall of the oil pipe. At the same time, the scraper rod is close to the heater, which can bring heat to a position far away from the heater, so that the waste oil in other places on the inner wall of the oil pipe can also be better heated.

[0019] 3. Place the push plate into the through hole so that the notch matches the scraper rod. At the same time, pull the pull plate, which drives the limit rod to move. The limit rod squeezes the spring and the slide rod. At this time, align the limit hole with the limit rod, release the pull plate, and the spring will push the limit rod into the limit hole, thereby fixing the push plate in the through hole. When the scraper rod scrapes the waste oil in the oil pipe, the waste oil will not flow out of the oil pipe mouth. After scraping is completed, pull the pull plate to disengage the limit rod from the limit hole, push the inner rod and the outer tube, and make the push plate push the waste oil in the oil pipe into the collection box, thereby removing the waste oil adhering to the oil pipe.
