Description

Technical Field

[0001] The utility model belongs to a filtering device, in particular to an oily sludge filtering device. Background Art

[0002] Oily sludge is one of the main pollutants generated during the development, production, and processing of oil. It is harmful to humans, plants, and aquatic organisms. The oil vapor evaporated into the air can irritate the skin, eyes, and respiratory organs, causing the soil to lose its ability to grow plants, making it difficult to treat and repair. When treating oily sludge, a filtration device is required to pre-treat the sludge to remove impurities and larger objects such as sand and gravel. However, existing filtration devices for treating oily sludge still have some drawbacks. For example, a high-efficiency oil drilling mud filtration device with publication number CN216934997U has a non-detachable screen and basket. Although the design allows the screen to vibrate through a vibration assembly and the basket to swing left and right through a disc, which can increase contact between the mud and the screen and basket, prevent mud accumulation and blockage of the screen and basket, and improve filtration efficiency, after long-term use, oily sludge will still solidify on the screen and basket, easily causing blockage, resulting in poor filtration effect and low filtration efficiency. Summary of the Invention

[0003] The utility model provides an oily sludge filtering device to solve the deficiencies of the prior art.

[0004] The filter screen is provided with a plurality of filter screens at the bottom of the filter screen, and a plurality of filter screens are provided at the bottom of the filter screen.

[0005] As a further improvement of the present invention, the locking mechanism includes a shell, a threaded rod, an L-shaped plug and a handwheel. The shell is fixed at the center position of the left end face of the filter screen, and threaded rods are rotatably connected on the inner walls of the upper and lower ends of the shell. Bevel gears I are fixed to the ends of the two threaded rods. A connecting rod is fixed to one end face of the handwheel, one end of the connecting rod passes through the left end face of the shell and is placed therein, and a bevel gear II is fixed to its end, and the bevel gear II is meshed with the two bevel gears I; mounting seats are fixed at the center positions of the upper and lower ends of the two through holes, and a slot is provided on the mounting seat. L-shaped plugs are threadedly connected to the outer walls of the two threaded rods, and one end of the two L-shaped plugs passes through the upper and lower walls of the shell and is placed in the slot.
