Description

Technical Field

[0001] This utility model relates to the field of oil sludge treatment technology, and in particular to an oil sludge mixing and conveying device. Background Technology

[0002] Oily sludge is a stable suspended emulsion liquid composed of water, oil, and suspended solids. It is frequently required for treatment in wastewater treatment plants of oil refineries, shipbuilding areas, and steel smelting plants.

[0003] Because oily sludge has poor dewatering effect and rapid sedimentation and caking, it needs to be stirred during transportation and treatment. There are some existing stirring devices for oily sludge treatment, such as the one with application number CN202421218206.7, entitled "A Stirring Device for Oily Sludge Treatment". It stirs through a vertically set stirring drum, but the discharge port area is small, which makes it easy for oily sludge to accumulate. In addition, the motor is located in the center of the stirring drum, which can affect the pouring of oily sludge. The reliability is not strong, and the stirring efficiency of oily sludge is not high, which affects the transportation and subsequent treatment of oily sludge. Utility Model Content
