Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
In the description of the present invention, unless explicitly stated and limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; the mechanical connection can be realized, and the point connection can be realized; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
In the present invention, unless expressly stated or limited otherwise, a first feature "above" or "below" a second feature may include both the first and second features being in direct contact, as well as the first and second features not being in direct contact but being in contact with each other through additional features therebetween. Moreover, a first feature being "above," "over" and "on" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is higher in level than the second feature. The first feature being "under", "below" and "beneath" the second feature includes the first feature being directly under and obliquely below the second feature, or simply means that the first feature is less level than the second feature.
In the description of the present embodiment, the terms "upper", "lower", "left", "right", and the like are orientation or positional relationships based on those shown in the drawings, merely for convenience of description and simplicity of operation, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the invention. Furthermore, the terms "first," "second," and the like, are used merely for distinguishing between descriptions and not for distinguishing between them.
The present embodiment provides a filter element, as shown in fig. 1, which includes a filter material 100, the filter material 100 includes a plurality of layers of filter cloth, and the pore diameter of the filter pores on the plurality of layers of filter cloth gradually decreases from the outer layer to the inner layer. Thereby realizing progressive filtration, intercepting various particle diameter impurities in the raw materials at different filter cloth layers, thereby improving the dirt receiving capacity of the filter element, improving the filtering effect, prolonging the service life of the filter element and realizing the effect of reducing the filtering cost.
Specifically, the filter element in this embodiment is used for filtering carbon fiber raw materials, when carbon fiber raw materials pass through the filter element, larger particulate matters are firstly trapped in the outer layer filter cloth, and smaller particulate matters are further filtered when moving towards the inner layer filter cloth, so that the capacity of the filter cloth is fully utilized. The filter element has the advantages of providing more efficient separation and filtration of particulate matters, improving the utilization rate of the filter element, reducing the waste of the filter element, saving the cost and greatly improving the filtration effect.
Optionally, the filter cartridge further includes a framework for supporting the filter 100 while preventing fluid surge. It is understood that the presence of the skeleton can effectively support the filter medium 100, preventing the filter medium 100 from vibrating or deforming in the event of high or fluctuating filter flow, which helps to maintain the stability and consistency of the filter, ensuring a continuous filtering effect.
Optionally, the skeleton includes a first support, which is disposed inside the filter 100. The first support member is disposed inside the filter medium 100, and can provide internal support and stability, so that the filter medium 100 can be uniformly stressed inside, and deformation and vibration of the filter medium 100 can be reduced. This helps to maintain consistency and integrity of the filter 100. Also, by adding a support inside the filter 100, the shape and pore size distribution of the filter 100 can be controlled more precisely, contributing to an improvement in filtration accuracy, which is important for applications requiring high-accuracy filtration, such as carbon fiber raw material filtration.
Optionally, the skeleton includes a second support member, which is disposed outside the filter material 100. The provision of the second support member outside the filter medium 100 can provide external support and stability, ensuring that the filter medium 100 is not deformed or damaged by external force. This helps to maintain the shape and integrity of the filter 100.
Optionally, the first support and the second support are both grid-like structures. The support of the lattice structure can provide uniform support, and can support the filter 100 on the inside as well as the filter 100 on the outside. This helps ensure that the filter medium 100 is uniformly stressed throughout the filtering process, reducing deformation and vibration of the filter medium 100. The support of the lattice structure helps to maintain the permeability of the fluid, which can maintain effective filtration performance at high flow rates or pressures.
Optionally, the filter cloth is made of inert inorganic fiber material. The inert inorganic fiber material can not chemically react with chemical substances in the filtering fluid, is favorable for maintaining the stability and the filtering efficiency of the filter cloth, and is particularly suitable for the application with high requirement on chemical stability. The inorganic fiber material is not influenced by temperature or chemical substances to expand, which helps to keep the size and shape of the filter cloth stable and ensure consistent filtering performance. Inert inorganic fiber materials generally do not degrade their performance due to extended storage times, and filter cloths can be stored for longer periods of time without fear of degradation. Therefore, the filter cloth made of inert inorganic fiber material has no chemical reaction, does not generate expansion, is not limited by the storage period, and improves the reliability of the filter cloth.
Optionally, as shown in fig. 1, the filter material 100 includes a plurality of crescent-shaped pleat structures 110, which effectively increases the filtering area, provides a uniform contaminant loading, and provides a large amount of receiving masonry, as compared to conventional scalloped structures.
The embodiment also provides a cartridge filter, which comprises a cartridge and the filter element, wherein the filter element is arranged in the cartridge and is used for filtering raw materials flowing through the cartridge. Because the filter core has multilayer filter cloth and progressive filtration characteristic, the cartridge filter can filter the raw materials with high efficiency, and the impurity of various particle diameters is held back, improves filtration efficiency.
Optionally, a feeding hole and a discharging hole are formed in the cylinder, the feeding hole is used for enabling raw materials to enter the cylinder, and the discharging hole is used for enabling filtered raw materials to flow out of the cylinder. The feed inlet allows raw materials to easily enter the cylinder, and the discharge outlet allows filtered raw materials to smoothly flow out of the cylinder, so that a convenient filtering flow is provided, and the operation complexity is reduced.
Optionally, the feed inlet is located at a first end of the barrel, and the discharge outlet is located at a second end of the barrel. The arrangement ensures that the raw materials flow unidirectionally, enter the cylinder from the first end, pass through the filtering process, and then flow out of the cylinder from the second end.
It is to be understood that the above examples of the present invention are provided for clarity of illustration only and are not limiting of the embodiments of the present invention. Various obvious changes, rearrangements and substitutions can be made by those skilled in the art without departing from the scope of the invention.
