A solid-liquid separation device for oil sludge treatment

Abstract

This utility model discloses a solid-liquid separation device for oil sludge treatment, relating to the technical field of oil sludge treatment equipment. It includes a separation shell, a drive platform fixedly connected to the top side of the separation shell, a drive rod rotatably connected between the inner walls of the drive platform, two separation plates fixedly connected to the bottom end of the drive rod, an overflow weir fixedly connected between the inner walls of the separation shell, and a drain pipe fixedly connected to one side of the separation shell. This utility model, through the guide pipe, guides the oil sludge to be treated into the bottom of the separation shell. The separation plates agitate the sludge, causing friction with the solid components and slowing them down to settle. Simultaneously, the overflow weir and drain pipe allow the liquid components that rise during agitation to cross the overflow weir under centrifugal force and enter the drain pipe for discharge, while the solid components are discharged from the bottom of the separation shell through a sludge discharge valve, avoiding secondary mixing of solid and liquid and improving the separation effect.

Description

Technical Field

[0001] This utility model relates to the technical field of oil sludge treatment equipment, specifically to an oil sludge treatment solid-liquid separation device. Background Technology

[0002] Oil sludge is an oily solid waste generated during oil extraction, transportation, refining, and oily wastewater treatment. It falls under the category of HW08 hazardous waste in the hazardous waste management catalog and is one of the main pollutants generated during oil and gas development and storage. Oil sludge is both a waste product from oilfield production and a resource; failure to treat and recover its oil content not only wastes resources but also pollutes the environment. Solid-liquid separation is necessary during oil sludge recovery. An existing solid-liquid separation device for oil sludge treatment (announcement number: CN221131303U) has at least the following defects in use: In the above scheme, the water and solids in the sludge are separated by the rotation of the separation cylinder. However, in actual use, after the sludge and water are separated, they are both discharged from the separation device through the bottom of the separation cylinder. Therefore, during collection, the water and sludge may mix again to a certain extent, affecting the separation effect. Therefore, a solid-liquid separation device for sludge treatment is needed. Utility Model Content

[0003] The main objective of this invention is to provide a solid-liquid separation device for oil sludge treatment, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A solid-liquid separation device for oil sludge treatment includes a separation shell. A drive platform is fixedly connected to the top side of the separation shell. A drive rod is rotatably connected between the inner walls of the drive platform. Two symmetrically distributed separation plates are fixedly connected to the bottom end of the drive rod. An overflow weir is fixedly connected between the inner walls of the separation shell. A drain pipe is fixedly connected to one side of the separation shell. The interior of the drain pipe is connected to the space enclosed by the inner wall of the separation shell and the outer wall of the overflow weir.

[0005] Preferably, a flow guide port is provided on the top side of the separation shell, the drive fixing platform covers the flow guide port, a flow guide tube is fixedly connected between the inner walls of the flow guide port, a cover connecting platform is fixedly connected to the top outer edge of the flow guide tube, and the bottom side of the cover connecting platform is fixedly connected to the top side of the separation shell.

[0010] Compared with the prior art, the present invention has the following beneficial effects: By using a guide pipe, the sludge to be treated is introduced to the bottom of the separator shell. The separation plates agitate the sludge, causing it to decelerate and settle due to friction with the solid components. Meanwhile, the overflow weir and drain pipe allow the liquid components that float to the surface during agitation to cross the overflow weir under centrifugal force and enter the drain pipe for discharge. The solid components are discharged from the bottom of the separator shell through the sludge discharge valve, thus avoiding secondary mixing of solid and liquid and improving the separation effect.
