AI Technical Summary

Technical Problem

Existing oily sludge separation equipment is difficult to effectively handle oily sludge with high viscosity, has low separation efficiency, and the slow diffusion rate of demulsifier leads to waste of reagents and uneven mixing.

Method used

A waste oil sludge reduction and separation device was designed. By using a reciprocating screw to drive a sealing plate and an air pump, the intermittent and uniform inflow of demulsifier and airflow impact are achieved. Combined with the rapid rotation of the rotating ring and screen plate, the mixing effect of demulsifier and waste oil sludge is improved.

Benefits of technology

It achieves rapid and uniform mixing and efficient separation of oily sludge, improving separation efficiency and avoiding problems such as reagent waste and uneven mixing.

Abstract

The invention discloses oil sludge reduction separation equipment, and belongs to the technical field of oil sludge treatment, the oil sludge reduction separation equipment comprises a separation tank, and a feeding pipe is fixedly mounted on the side wall of the separation tank. According to the scheme, the plugging plate is arranged, in the rotating process of the reciprocating screw rod, the reciprocating screw rod drives the plugging plate to move through the threaded sleeve, and after the plugging plate is not in contact with the bottom wall of the feeding box, a demulsifier in the feeding box can flow into the feeding cavity through the hollow rod and uniformly flow into the separation tank through the feeding holes in the feeding cavity; when the threaded sleeve drives the plugging plate to move downwards, the plugging plate gradually makes contact with the bottom wall of the feeding box, so that the feeding box can be plugged, the demulsifying agent in the feeding box cannot continuously flow into the hollow rod at the moment, in other words, under the action of the plugging plate, the demulsifying agent can intermittently and uniformly flow into the separation tank, and therefore the demulsifying agent can be separated from the separation tank. Therefore, the demulsifier and the oil sludge are quickly and uniformly mixed together, and the effect of improving the oil sludge separation efficiency is achieved.
