Abstract

The invention discloses a bidirectional extrusion oily sludge treatment device. The device comprises a two-way extrusion cylinder and a standing layering box, the two-way extrusion cylinder is fixed above the standing layering box and communicates with the standing layering box, a main supporting frame and an auxiliary supporting frame which are used for supporting and fixing the two-way extrusioncylinder are arranged between the two-way extrusion cylinder and the standing layering box, and a feeding hopper is arranged at the top of the two-way extrusion cylinder. When the device is used forcarrying out treatment work; oily sludge is conveyed into the two-way extrusion cylinder through the feeding hopper. A first drive motor is started, a forward-rotation packing auger is used for conveying sludge to an extrusion ring and extruding the sludge; liquid components and solid components in the sludge are separated; under the extrusion effect, the sludge is transferred into the standing layering box through a screening channel, meanwhile, a second driving motor is started, the sludge is extruded from the other side of the two-way extrusion cylinder through a reverse selection packing auger, the problem of material accumulation at the tail of the extrusion cylinder easily caused by one-way extrusion is solved, and the liquid precipitation efficiency is improved.

Description

technical field

[0001] The invention relates to petrochemical equipment, in particular to a two-way extrusion oily sludge treatment device. Background technique

[0002] At present, the waste oil produced in the crude oil production process generally only undergoes simple heating and gravity sedimentation treatment in the waste oil recovery process to improve its fluidity and reduce pollution according to the level of mechanical impurities, viscosity and temperature in the waste oil. The silt in pipelines and processing equipment caused by mud and sand in the oil, and even without any pretreatment, the dirty oil is directly mixed back into the fresh production fluid. The stability of the oil-water emulsion in oil, the dirty oil mixed into the freshly produced fluid often leads to the increase of the oil content in the water released by the free water remover, the increase of the dehydration current of the electric dehydrator or even the collapse of the electric field, and th...
