Filtration structure of oil-water separator

Abstract

A filtration structure device for an oil-water separator mainly comprises a filter screen body and a plurality of filter screens. Its characteristic is that the filter screen is a single piece formed by combining a U-shaped groove frame and a single, integrally bent filter screen sheet. Each filter screen sheet is composed of a plurality of sheet-like structures, integrally bent and arranged with equal widths and intervals. Each sheet also has a plurality of equally spaced pleated areas. This allows the filter to effectively filter a mixture of oily cutting fluid and debris, which would otherwise be subject to significant turbulence and bubbles when pumped in. However, when filtered through this filter structure device, the filter exhibits stable flow, the ability to trap floating oil and debris, and the ability to block bubbles. This results in a filtrate with less oil and debris, stable flow, and no bubble generation.

Description

[Technical Field]

[0001] This invention relates to a filtration structure device for an oil-water separator, and more particularly to a filter screen structure device in which a single filter screen can be replaced and cleaned, thereby saving costs. In addition, the filter screen has the structural feature of being composed of multiple sheet-like bodies arranged in an integral bending pattern with equal width and equal intervals, and each sheet-like body also has multiple equally spaced pleated areas. This allows the filtrate to obtain a stable flow and a filtration result without bubbles, floating oil, or debris during the filtration process. It is a unique and economically efficient invention. [Previous Technology]

[0002] Please refer to Figure 1. Generally, in commercially available oil-water separators 2, the filter structure used for filtration inside the machine is a one-piece square filter block 1. Since the interior of this square filter block 1 is composed of multiple plates connected in a cross shape, when filtering the raw liquid 7, which is a mixture of oily cutting fluid and debris, drawn by the pump, when it is drawn in from the inlet 201 and sprayed upwards, it will first be blocked by the baffle plates 3 and 4, and slowly fill the first placement area 202. When the drawn raw liquid 7 overflows the baffle plate 3, it enters the filtration process. At this time, the raw liquid 7 will be filtered by the square filter block 1. However, during the process of the raw liquid 7 being drawn in by the pump, it will cause the raw liquid to be filtered. Liquid 7 generates surface disturbances and numerous bubbles. However, the conventionally used square filter block 1, with its parallel array of pores, cannot effectively stabilize the flow and prevent bubbles. Furthermore, its effectiveness in removing floating oil and debris is limited. Consequently, the filtered liquid 8 slowly overflows through the separator 5 and flows into the second placement zone 203, filling it with bubbles, oil, and debris, thus reducing filtration efficiency. After a period of filtration, the square filter block 1 becomes clogged due to oil and debris buildup in its central area, requiring complete replacement and preventing effective cleaning. This prevents the reuse of the filtered liquid 8, necessitating a second filtration and increasing costs. Therefore, the industry is eager to improve and design a system that facilitates cleaning, achieves effective filtration, ensures stable flow of the filtered liquid without bubbles, and reduces filtration costs.

[0003] In view of this, the inventor of this case, based on his many years of research and development experience in related fields, conducted in-depth research on the aforementioned deficiencies and actively sought solutions based on the aforementioned needs. After a long period of hard work and multiple tests, he finally completed this invention, which solves the shortcomings of conventional methods and enhances its unprecedented progressiveness and practicality. [Summary of the Invention]

[0004] Therefore, the main objective of this invention is to provide a "filtration structure device for an oil-water separator", which is designed as a decomposable and individually replaceable component structure, and also allows for easy cleaning of the components, thereby reducing the cost required in the filtration process.

[0005] A secondary objective of the present invention is to provide a "filtration structure device for an oil-water separator". In addition to the structural feature that the single-piece filter screen of the present invention is formed by multiple sheet-like bodies of equal width and equal intervals into a single shape, the sheet-like bodies are also designed with a plurality of pleated areas. This allows the more turbulent liquid surface to be stabilized during the filtration process. Furthermore, due to the distribution structure of the multi-layer filter screen, it can achieve better adhesion of floating oil and blockage of debris, and can also effectively block bubbles generated by liquid surface disturbance.

Implementation Method

[0006] In order to provide a more detailed and clear understanding of the purpose, effects and structural features of the present invention, the following preferred embodiments are described in conjunction with the accompanying drawings.

[0007] Please refer to Figures 2 and 3 first. The present invention is a filter structure device for an oil-water separator, which mainly comprises a filter screen body 9 and a plurality of filter screens 10. The filter screen body 9 is slightly U-shaped, but on both sides of the U-shape, there is an integrally connected U-shaped groove 903. On the U-shaped groove 903, there are a plurality of slots 901 running from top to bottom. At the bottom of the filter screen body 9, there is a hollow part 902.

[0008] The filter screen 10 is a single piece formed by combining a U-shaped groove frame 1001 and a filter screen sheet 1002 that is bent into shape. The filter screen sheet 1002 is composed of a plurality of sheet-like bodies 10021 with equal width and equal intervals, and each sheet-like body 10021 has a plurality of equally spaced wrinkled areas 10022.

[0009] During assembly (see Figure 2), since the U-shaped groove frame 1001 and the filter screen 1002 have been combined into a single piece by machine equipment before leaving the factory, the filter screen 1001, which is fixed together as a whole, is then inserted into the slot 901 of the filter screen body 9 in sequence and inserted all the way to the bottom, so that the filter screen 10 is laid flat across the hollow part 902. In this way, the assembly of the filter screen structure device 11 of the present invention is completed.

[0010] In use (see Figures 3 and 4), the filter structure device 11 is first placed in the filter structure device receiving area 12 of the oil-water separator 2. When the pump is started (not shown in the figure), the raw liquid 7 to be filtered will be drawn into the first placement area 202 through the inlet 201. Since the raw liquid 7 is composed of oily cutting fluid and debris from the processing, when the pump draws the raw liquid 7 into the first placement area 202, the flow rate of the raw liquid 7 is relatively fast. In addition, due to the arrangement of the baffles 3 and 4, a large bubble phenomenon will be generated when the raw liquid 7 is drawn into the first placement area 202 (due to the mixing and disturbance of oil and cutting fluid). As more and more raw liquid 7 is drawn, it will continuously overflow the baffles 3 and enter the filter structure device 11 of the present invention to start filtration.

[0011] (Please refer to Figure 2 for reference) At this time, because the filter structure device 11 of the present invention has a plurality of filter screens 10, and the filter screens 1002 within the filter screens 10 are composed of a plurality of sheet-like bodies 10021 arranged in an integrally bent manner with equal width and equal spacing, and each sheet-like body 10021 also has a plurality of equally spaced pleated areas 10022, when the original liquid 7 with more bubbles and faster liquid surface agitation enters the filter structure device 11, due to the filtration The mesh structure device 11 has a plurality of filter screens 10, which can effectively block debris and, due to the distribution of the layers of filter screens 10, can sequentially adsorb and stick floating oil (i.e., oily substances) and block bubbles. In addition, it can stabilize the surface disturbance of the original liquid 7, so that the filtered liquid 8 has a stable flow after entering the second placement area 203. The filtered liquid 8 is free of debris and oily substances, and no bubbles are generated. Thus, the filtered liquid 8 has a better filtration quality and does not need to be filtered a second time.

[0012] Since the filter screens 10 in the filter screen structure device 11 of the present invention can all be removed individually for cleaning or replacement, when a layer of filter screen 10 is dirty, it can be easily removed and cleaned by visual inspection. If it cannot be cleaned due to long-term use, or if it is clogged with debris or too much oil, a single filter screen can be replaced. In this way, the cost required is also lower.

[0013] In summary, the filter structure device of the oil-water separator of the present invention was designed by the inventor with great care and ingenuity. It is not only practical and convenient, but also quick to assemble and use, and easy to replace and clean individual components. It meets the requirements of the Patent Law for invention patents. Therefore, this application is filed in accordance with the law. I respectfully request the examiners of the Bureau to review and grant the patent. I am truly grateful.

[0014] However, the above description is only a preferred embodiment of the present invention and is not intended to limit the patent scope of the present invention. Therefore, all equivalent structural changes made by applying the present invention specification and application scope are similarly included within the scope of the present invention and are hereby stated.
