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 provides a center-feeding-type multilayer circulating wastewater treatment separator, which includes an internally hollowed shell body. A water inlet and a water outlet are disposed on the shell body. A filter medium layer is disposed in the middle of the shell body. The middle part of the upper end surface of the filter medium layer is convex upwardly. The middle part of the lower end surface of the filter medium layer is concaved upwardly towards the interior of the filter medium layer. An elastic pressing board is arranged on the upper end surface of the filter medium layer, while the lower end surface is provided with an elastic jacking board. A first support rod is connected to the middle of the elastic pressing board. A plurality of first push-and-pull rods are connected to periphery of the elastic pressing board. The forces of the first support rod and the first push-and-pull rods on the elastic pressing board are in the same or opposite direction. A vertical separation board is arranged in the middle of the filter medium layer so as to separate the filter medium layer into two parts completely. The separator has simple structure and is high in processing load on the basis of small total size, is greatly increased in processing speed and purifying rate, and is suitable for oil and water separation in different types due to the character of varying structure.

Description

technical field [0001] The invention relates to the field of liquid separation devices, in particular to a mid-entry multi-layer circulating sewage treatment separator. 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 too ...
