Description

Technical Field

[0001] This utility model relates to the field of nylon woven fabric technology, specifically to a high-efficiency alkali-resistant nylon monofilament woven fabric. Background Technology

[0002] Nylon monofilament filter cloth is widely used in equipment such as filter presses and belt filters in mining, metallurgy, coal, and chemical industries for solid-liquid separation due to its advantages such as smooth surface, high strength, wear resistance, non-clogging, and easy cleaning and regeneration.

[0003] However, existing nylon monofilament filter cloths often use a dense plain weave, which results in high filtration resistance and easy clogging, leading to poor backwashing performance. Summary of the Invention

[0004] Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a high-efficiency alkali-resistant nylon monofilament woven fabric, solving the problems mentioned in the background section.

[0005] Technical solution To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency alkali-resistant nylon monofilament woven fabric, comprising a fabric body. The fabric body is woven using a four-end twill variation weave, which forms a filter surface on one side and a support surface on the other side.

[0006] The interlacing pattern of the warp and weft yarns on the filter surface is as follows: one warp yarn floats continuously above three weft yarns, then sinks below one weft yarn, and this pattern repeats. This organization creates uniform, long, floating warp lines on the filter surface. Due to the small number of warp and weft yarn interlacing points, the filter surface is very smooth and flat, making it difficult for solid particles to adhere. Even if they do adhere, they are easily removed, thus significantly reducing filtration resistance and improving filtration efficiency and backwashing effect.

[0007] The interlacing pattern of the warp and weft yarns on the support surface is as follows: one warp yarn floats above one weft yarn, then sinks below three weft yarns, and this pattern repeats. This organization results in a much larger number of warp and weft yarn interlacing points on the support surface compared to the filter surface. These dense interlacing points form a tightly structured and robust support network, giving the filter cloth extremely high mechanical strength, dimensional stability, and abrasion resistance, enabling it to withstand significant filtration pressure differentials and mechanical wear.

[0008] Preferably, both the warp and weft yarns of the fabric are made of alkali-resistant nylon monofilament. This material itself has excellent alkali corrosion resistance, high strength, and abrasion resistance.

[0009] Preferably, the filter cloth has fixed side edges on both sides along its length. These fixed side edges are used to enhance the edge strength of the filter cloth and facilitate installation and fixation on filtration equipment.

[0010] Preferably, a reinforcing rib is embedded within the fixed side along its length. This further improves the strength of the fixed side.

[0011] Preferably, the reinforcing ribs are two in number and arranged in parallel to provide uniform support.

[0012] Preferably, the cross-section of the reinforcing rib is circular. This shape has no sharp angles, the stress is evenly distributed, and it is not easy to wear down the side material. Beneficial effects

[0013] This invention provides a high-efficiency alkali-resistant nylon monofilament woven fabric. It has the following beneficial effects: This high-efficiency alkali-resistant nylon monofilament woven fabric features a long warp float on the filter surface, fewer interlacing points, and an extremely smooth surface. This effectively reduces the adhesion of filter media, lowers filtration resistance, and makes backwashing or scraper unloading more thorough and efficient.

[0014] This high-efficiency alkali-resistant nylon monofilament woven fabric, through the four-sided twill weave variation of the fabric body, forms a filter surface and a support surface with different functions on the same piece of fabric. The filter surface is smooth, which is conducive to filtration and dust removal; the support surface is dense, which provides strong mechanical support, perfectly solving the contradiction between filtration performance and mechanical strength.

[0015] This high-efficiency alkali-resistant nylon monofilament woven fabric, with its fixed sides featuring built-in reinforcing ribs, greatly enhances the strength of the filter cloth edges, avoiding the risk of edge tearing during installation and operation, and improving the operational reliability of the equipment.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] This utility model embodiment provides a high-efficiency alkali-resistant nylon monofilament woven fabric, such as... Figure 1-2 As shown, the fabric includes a body 1, which is woven on a loom using a four-end twill weave pattern for both warp and weft yarns. Both warp and weft yarns are made of alkali-resistant nylon monofilament with a diameter of 0.15 mm.

[0020] From the perspective of the filter surface, its interlacing pattern is as follows: one warp yarn floats continuously above three weft yarns, and then sinks below one weft yarn, which can be regarded as the warp surface effect of 1 / 3 twill weave. This surface forms a smooth filter surface.

[0021] With its long radial float and few interlacing points, the filter surface is extremely smooth, effectively reducing the adhesion of filter media and lowering filtration resistance. At the same time, it makes backwashing or scraper unloading more thorough and efficient.

[0022] From the perspective of the supporting surface, its interlacing pattern is as follows: one warp yarn floats on top of one weft yarn, and then sinks below three weft yarns, which can be regarded as the weft surface effect of a 3 / 1 twill weave. This surface forms a solid supporting structure.

[0023] Through the four-fold twill weave of the fabric 1, filter surfaces and support surfaces with different functions are formed on the same piece of fabric 1. The filter surface is smooth, which is conducive to filtration and dust removal; the support surface is dense, which provides strong mechanical support, perfectly solving the contradiction between filtration performance and mechanical strength.

[0024] In some embodiments, fixed side edges 2 are connected to both sides of the fabric body 1 via high-frequency heat fusion. These fixed side edges 2 are wear-resistant PVC-coated strips. Two circular reinforcing ribs 3 are embedded parallel to each other along the entire length of each fixed side edge 2. In this embodiment, the reinforcing ribs 3 are made of stainless steel wire.

[0025] The fixed side 2 with built-in reinforcing ribs 3 greatly enhances the strength of the filter cloth edge, avoids the risk of edge tearing during installation and operation, and improves the operational reliability of the equipment.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
