Problems solved by technology

How to effectively separate and recycle oil and water has been studied for many years in practice and theory. The existing oil-water separation devices for sewage treatment mainly use air suspension, filter medium filtration, etc., and need to go through multiple links to complete , its main disadvantage is that it can only be used in large-scale processing occasions, the device and its processing process are too complicated, time-consuming, and the separation efficiency is too low, and its purification rate cannot meet the relevant national standards, making the cost too high

Embodiment Construction

[0020] Below in conjunction with accompanying drawing, the present invention will be further described:

[0021] As shown in the accompanying drawings, the present invention improves the overall structure on the basis of the traditional separator, especially optimizes the structure of the filter medium layer. For different oil-water separations, different medium filtration is required, and its filtration speed and The purification rate is one aspect, and the full utilization of the filter medium layer also needs to be considered. The structure of the filter medium layer of the present invention is different from the square and flat pattern of the existing filter medium. The surface that first contacts with oil and water is set to be non-planar, which can be a downwardly concave arc surface or an upwardly convex arc surface. When controlling the filtration rate of the filter medium layer, the oil and water are evenly distributed on the surface of the filter medium layer, withou...

Abstract

The invention discloses a variable medium layer sewage treatment oil-water separator. The separator comprises an inner hollow housing, a water inlet is arranged at the upper end of the housing, a water outlet is arranged at the lower end of the housing and a filter medium layer is arranged in the middle in the housing. The separator is characterized in that the filter medium layer is a compressible and resilient elastic structure, the upper end surface is a structure having the concave middle, the water inlet is arranged at the edge of the upper end of the housing, the lower end surface of the filter medium layer is a structure having the raised middle, the upper end surface of the filter medium layer is provided with a resilient pressing plate, the lower end surface of the filter medium layer is provided with a resilient top plate, the resilient pressing plate and the resilient top plate are arranged movably, the middle of the resilient pressing plate is connected to a support rod 1, and the periphery of the resilient pressing plate is connected to multiple push-pull rods 1. The separator has a simple structure, a small overall volume, a large treatment amount, a high treatment rate and a large purification rate. Through the variable structure, the separator is suitable for separation of different types of oil and water.

Description

technical field [0001] The invention relates to the field of liquid separation devices, in particular to an oil-water separator for variable medium layer sewage treatment. Background technique [0002] Oil-water separation is an essential process operation link in daily life and industry. It is very important for reducing environmental pollution or reusing resources, especially in the process of sewage treatment. How to effectively separate and recycle oil and water has been studied for many years in practice and theory. The existing oil-water separation devices for sewage treatment mainly use air suspension, filter medium filtration, etc., and need to go through multiple links to complete , its main disadvantage is that it can only be used in large-scale processing occasions, the device and its processing process are too complex, time-consuming, and the separation efficiency is too low, and its purification rate cannot meet the relevant national standards, making the cost t...
