Description

Technical Field

[0001] The utility model relates to the technical field of oily sludge treatment, in particular to an oily sludge cleaning device. Background Art

[0002] Oilfield oily sludge treatment stations need to reduce the amount of oily sludge. Based on the principle that oil floats on the water, most of the oil recovery in oily sludge cleaning devices currently use overflow to discharge oil. At present, the oily sludge is generally sent to a mixing tank, and chemical cleaning agents and hot water are introduced into the mixing tank for stirring, so that the oil floats up and then overflows and discharges. Due to the presence of agglomerated sludge in some oily sludge, the agglomerated sludge sinks to the bottom and is difficult to stir and remove the oil. Utility Model Content

[0003] The purpose of the present application is to provide an oily sludge cleaning device to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical scheme: an oil-containing sludge cleaning device comprises a cleaning tank, wherein a motor is fixedly installed on the top of the cleaning tank, and the output end of the motor drives a rotating shaft connected to the inside of the cleaning tank, and a horizontal inclined net is fixedly installed near the top of the cleaning tank, and a crushing knife located above the inclined net and close to the inclined net is fixedly installed on the rotating shaft, and a stirring blade is also fixedly installed on the rotating shaft, and the stirring blade is located below the inclined net, and a scraper is fixedly installed on the bottom end of the rotating shaft, and the scraper is in contact with the bottom of the inner cavity of the cleaning tank, and a slide plate is slidably connected to the inside of the cleaning tank, and the slide plate is located between the inclined net and the stirring blade, and a hydraulic rod is fixedly installed at the bottom end of the inclined net, and the output end of the hydraulic rod is fixedly connected to the top of the slide plate, and an oil suction pipe is fixedly installed on the rear side of the slide plate, and the bottom end of the oil suction pipe is fixedly installed and connected with a plurality of oil suction nozzles, and the oil suction pipe is connected with an oil delivery hose that leads to the outside of the cleaning tank.

[0005] Preferably, the top of the cleaning tank is provided with a cleaning agent and hot water inlet communicated with the interior thereof.

[0006] Preferably, one side of the cleaning tank is provided with an oil sludge input port leading to the chamber above the inclined net.

[0007] Preferably, a sewage outlet communicating with the interior of the cleaning tank is provided on one side of the bottom end thereof, and a valve is fixedly mounted on the sewage outlet.

[0008] Preferably, a debris discharge port is installed at the lowest end of the inclined net on one side of the cleaning tank, and a valve is fixedly installed on the debris discharge port.

[0009] Preferably, the inner wall of the cleaning tank is provided with a thermal insulation coating.

[0010] In summary, the technical effects and advantages of the utility model are:

[0011] In the utility model, the motor drives the rotating shaft to rotate, thereby driving the crushing knife, the scraper and the stirring blade to rotate. The oil sludge entering the cleaning tank is intercepted and agglomerated on the inclined net, and the crushing knife crushes the sludge. The sludge falls into the lower chamber and is scraped up by the scraper. At the same time, the stirring blade drives the sludge, the cleaning agent and the water to stir, so that the oil and liquid of the oil sludge can be fully separated. The oil suction position of the oil suction nozzle can be adjusted by adjusting the height of the slide plate through the hydraulic rod, so as to better absorb the oil and reduce the amount of water sucked out.
