Description

Technical Field

[0001] The utility model belongs to the technical field of non-woven fabric filtering, and in particular relates to a non-woven fabric filtering structure with oil resistance. Background Art

[0002] Non-woven fabric filtration is a commonly used filtration method. Its filtration effect mainly depends on the physical effects of the material's pores and friction between fibers, gravity, surface tension, etc. The following are some of the main features and applications of non-woven fabric filtration:

[0003] Filtration principle: The internal structure of non-woven fabrics has a regular distribution of pores, which can effectively isolate most impurities such as suspended matter and solid particles. When liquid or gas passes through the non-woven fabric, the impurities will be trapped in the fiber gaps of the non-woven fabric, thus achieving the purpose of filtration.

[0004] Factors affecting filtration accuracy: The filtration accuracy of non-woven fabrics is affected by many factors, including fiber thickness, yarn density, thickness of non-woven fabrics, etc. Generally speaking, the finer the fiber, the greater the yarn density, and the thicker the non-woven fabric, the higher the filtration accuracy.

[0005] Application fields: Non-woven fabric filtration is widely used in various industries, medical treatment, environmental protection and other fields. For example, in industrial production, non-woven fabric filtration can be used for liquid filtration, air filtration, etc.; in the medical field, non-woven fabric filtration can be used to make masks, surgical gowns, etc.; in the environmental protection field, non-woven fabric filtration can be used for sewage treatment, air purification, etc.

[0006] A common disadvantage of nonwoven fabrics (also known as nonwovens) is that they are generally not resistant to oil stains. This is mainly because the structure and material of nonwoven fabrics make them easy to absorb and retain grease, thus reducing their filtration performance and service life.

[0007] Non-woven fabrics are thin sheets or felt-like products made by directly bonding or entangled fibers through physical or chemical methods, rather than weaving or knitting through traditional textile methods. This structure makes non-woven fabrics have excellent air permeability, softness and processability, but it also means that they are more easily contaminated by oil. When non-woven fabrics come into contact with oily liquids, the grease will quickly penetrate into the gaps between the fibers and may even dissolve part of the fiber material. This will not only reduce the filtration efficiency of the non-woven fabric, but may also cause its structure to become loose and lose its original strength and durability. In addition, if non-woven fabrics are mixed and used in the form of an oleophobic layer, the accumulated oil will lead to a decrease in filtration efficiency, obstruction of gas-liquid flow, and an increase in pressure on the filtration structure.

[0028] A non-woven filter structure with oil resistance, comprising:

[0029] Positioning shell 1;

[0030] An oil removal component is arranged on the outer wall of the positioning shell 1, wherein: the oil removal component includes a diverter shell 4, an oleophobic layer 5, a scraper 6, a pressure ring 7, a transmission blade 9 and a snap plate 10, the diverter shell 4 is sleeved on the outer wall of the positioning shell 1, the oleophobic layer 5 is embedded in the inner wall of the diverter shell 4, the scraper 6 is rotatably embedded in the inner wall of the diverter shell 4, the transmission blade 9 is rotatably embedded in the inside of the pressure ring 7, the snap plate 10 is rotatably inserted at the top edge of the outer wall of the transmission blade 9, one end of the snap plate 10 matches the protruding end of the scraper 6, the pressure ring 7, the positioning shell 1 and the diverter shell 4 match each other, and the outer wall of the positioning shell 1 is sleeved with a non-woven fabric 2.

[0031] In a specific embodiment of the utility model, the degreasing component can minimize the accumulation of oil in the oleophobic layer 5, reduce the burden of the oleophobic layer 5, and increase its service life while ensuring the function of filtering oil to the greatest extent. At the same time, it can avoid the problem of oil penetrating into the interior of the non-woven fabric 2, which causes the non-woven fabric 2 to deteriorate. After installation, the gas enters the diverter shell 4, and the gas first passes through the oleophobic layer 5 to block the oil mist particles. After the oil mist gathers, it adheres to the oleophobic layer 5, and then the gas enters the constraint net 3 and the non-woven fabric 2 through the air permeable hole 402 to complete the filtration. After the oil mist accumulates, it gathers and adheres. The gas drives the transmission blades 9 to rotate, and the scraper is driven to rotate by the snap plate 10, so that the oil mist is driven by the scraper and slowly drips to the bottom of the inner wall of the diverter shell 4, and the sewage is discharged through the sewage discharge hole 401.

[0032] Specifically, a sealing ring 8 is sleeved on the outer wall of the snap plate 10 .

[0033] In a specific embodiment of the present utility model, the sealing ring 8 can ensure the stability of gas output.

[0034] Specifically, the inner wall of the split shell 4 is provided with air holes 402 .

[0035] In the specific embodiment of the present invention, the air holes 402 can ensure stable gas flow.

[0036] Specifically, a drain hole 401 is provided at the bottom of the inner wall of the diverter shell 4 .

[0037] In a specific embodiment of the present utility model, a drainage hole 401 is provided at the bottom of the inner wall of the flow dividing shell 4, which can facilitate drainage and collection of oily dirt.

[0038] Specifically, the outer wall of the non-woven fabric 2 is covered with a restraining net 3 .

[0039] In a specific embodiment of the present utility model, the outer wall of the non-woven fabric 2 is provided with a restraining net 3 to ensure stable restraint of the non-woven fabric 2 .

[0040] Specifically, one end of the scraper blade 6 is convex, and one side of the outer wall of the scraper blade 6 is in contact with the outer wall of the oleophobic layer 5 .

[0041] In a specific embodiment of the present invention, one side of the outer wall of the scraper blade 6 is in contact with the outer wall of the oleophobic layer 5 to ensure that the oil stains can be scraped off.

[0042] Working principle:

[0043] Through the collecting component, the fallen rice can be collected to avoid the rice splashing due to impact and clogging the inner wall of the restraining shell 6, resulting in the mixing of a large amount of rice husks, reducing the cleanliness of rice husk separation, and avoiding a large amount of splashing rice to block the rice husk discharge channel. First, the mixture of rice husks and rice is injected into the interior of the storage bin 3, so that the mixture falls to the inclined surface of the diversion shell 4, and then the airflow generated by the blower 2 blows the mixture. Due to the different masses of rice and rice husks, the rice husk is discharged from the outer shell 1 along the guide shell 5, and the rice falls to the inner wall of the restraining shell 6. Most of the rice falls into the collecting bin 7 through the discharge port 8 through the guide plate 9, and then the splashed rice falls to the bottom edge of the inner wall of the restraining shell 6. Then the airflow obtained by the guide shell 5 makes the airflow stick to the bottom of the inner wall of the restraining shell 6, so that the rice is brought into the discharge port 8 by the airflow, thereby completing the anti-clogging function.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
