Abstract

The invention discloses a drum screening machine comprising a screen drum screen mesh, a motor for driving the screen drum screen mesh to rotate, a material inlet connected with the screen drum screen mesh, a waste material outlet connected with the screen drum screen mesh, and a pedestal for supporting the screen drum screen mesh. The drum screening machine is characterized by also comprising two cleaning water pipes and a booster water pump for pressurizing the cleaning water. The two cleaning water pipes are respectively longitudinally arranged on the inner side and the outer side of the screen mesh, the two cleaning water pipes are each provided with a plurality of holes, and cleaning water is provided for oil sludge in the screen mesh through the plurality of holes. According to the technical scheme of the invention, sundries in hardened tank bottom sludge and hardened pool bottom sludge can be effectively sorted out, and the screening efficiency is increased, so that the treated fluidization oil sludge meets feeding requirements of subsequent oil sludge treatment equipment.

Description

technical field [0001] The invention relates to the field of oil field sludge treatment, in particular to a drum screening machine. Background technique [0002] At present, there are tank bottom mud and pool bottom mud that have been stored for a long time in the oil field, have not been treated in time, and are mixed with various garbage and waste to form compaction. Because the above-mentioned sludge and oily soil have different particle sizes, complex components and solidification, it is difficult to directly treat them with the existing technology, so pretreatment must be carried out first. [0003] Existing trommel screens are mostly used for particle size classification in mining machinery and garbage treatment processes. It uses a cylindrical sieve body for rotary motion to classify materials according to particle size. The screen surface is generally a woven mesh. The screen body is installed obliquely. The sieved material is turned in a spiral shape with the rota...
