Shale oil solid-liquid separator

Abstract

The present invention relates to a shale oil solid-liquid separator, which is composed of a separator body, an intermittent rotation shaft, an oil inlet pipe bracket, a left plate module, a right plate module, a left spring module, a right spring module, a board support module and a control module; the intermittent rotation shaft is installed in a central baffle plate of the separator body in a rotary mode, each plate edge end of the left plate module and the right plate module are hinged to the inner side wall of the separator body, the central parts of the left plate module and the right plate module are connected to the right and left inner side walls of the separator body by the left spring module and the right spring module; the oil inlet pipe bracket is fixedly connected with the intermittent rotation shaft, a board support modules are respectively fixedly connected to the intermittent rotation shaft by a support pin; the invention adopts an intermittent operation mode, thereby the uninterruptedly filtration work is realized when sand unloading is required after the solid-liquid separation, by dividing into two boxes and cooperating with the intermittent movement, the normal operation is realized for most of the time, the separation efficiency is improved, by increasing a control module, automatic control of the solid-liquid separation process can be realized.

Description

technical field [0001] The invention belongs to the field of solid-liquid separation equipment, and in particular relates to a simple and efficient solid-liquid separator for shale oil. Background technique [0002] The shale oil solid-liquid separator is mainly used to separate the sand particles in the shale oil mixture produced. The current shale oil solid-liquid separator mainly has the following deficiencies: [0003] 1. Most of the existing shale oil solid-liquid separation equipment uses internal parts driven by motors to separate, and the internal parts include various forms of filter columns, such as ceramic type, winding type, fiber-infused type, etc. The structure is complex, there are many rotating parts, it is easy to cause the rotating parts to stop due to internal sundries, and the maintenance process is complicated. [0004] 2. Most of the current shale oil solid-liquid separators need to be cleaned, and the filter screen needs to be cleaned after a period ...

AI Technical Summary

Problems solved by technology

The structure is complex, there are many rotating parts, it is easy to stop the rotating parts due to internal sundries, and the maintenance process is complicated

[0004] 2. Most of the current shale oil solid-liquid separators need to be cleaned, and the filter screen needs to be cleaned after a period of filtration, resulting in low filtration and separation efficiency

If a backwashing device is added, the structure of the separator will be complicated, and the cost will increase accordingly

[0005] 3. The current shale oil solid-liquid separator has relatively high energy consumption and is uneconomical because the motor drives the internal parts to rotate.
