Description

Technical Field

[0001] The utility model relates to the technical field of filter media, and specifically, to a filter media with good air permeability. Background Art

[0002] Filtration is the general term for a large class of unit operations, which is the process of purifying and refining fluids through special devices. There are many ways of filtration. Filter media is the general term for water treatment filtration materials, mainly used for the filtration of domestic sewage, industrial sewage, pure water, and drinking water to achieve the renewable and sustainable utilization of water resources. However, most existing filter media have relatively low strength and do not have good wear resistance, and are prone to wear.

[0003] The existing patent No. CN202122799202.5 discloses a filter media with high filtration strength, including a first nylon layer and a hemp fiber layer. The first nylon layer is fixedly connected to the first dust-facing layer, the first dust-facing layer is fixedly connected to the dense layer, the hemp fiber layer is fixedly connected to the dense layer, and the hemp fiber layer is also fixedly connected to the second dust-facing layer, and the second dust-facing layer is fixedly connected to the second nylon layer. By weaving every two strands of the second longitudinal nylon threads and the second transverse nylon threads, the overall strength of the second nylon layer is enhanced. The overall service life is improved through the first nylon layer and the second nylon layer. While the overall strength is improved through the hemp fiber layer, the overall flexibility is also improved. The overall filtration performance is enhanced through the first dust-facing layer and the second dust-facing layer. At the same time, the dense layer ensures sufficient filtration.

[0004] The following problems exist in the implementation of the above solution: Each layer of this device is tightly connected without leaving enough gaps, and there are more layers set, resulting in a relatively thick overall structure. Therefore, the air permeability of this filter media is poor, the resistance is large, the fluidity during water resource filtration is reduced, and thus the filtration efficiency is reduced. For this reason, we provide a filter media with good air permeability to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a filter media with good air permeability, and solve the problem that in the prior art, each layer of this device is tightly connected without leaving enough gaps, and there are more layers set, resulting in a relatively thick overall structure. Therefore, the air permeability of this filter media is poor, the resistance is large, the fluidity during water resource filtration is reduced, and thus the filtration efficiency is reduced.

[0006] The utility model provides the following technical solution: A filter media with good air permeability, including a nylon layer and a hemp fiber layer. A first bamboo charcoal fiber layer is fixedly connected to the bottom end of the nylon layer, and the first bamboo charcoal fiber layer is fixedly connected to the hemp fiber layer. A second bamboo charcoal fiber layer is fixedly connected to the bottom end of the hemp fiber layer, and a filter cotton is fixedly connected to the bottom end of the second bamboo charcoal fiber layer.

[0007] As an optimization of the above technical solution, the thicknesses of the first bamboo charcoal fiber layer, the hemp fiber layer, and the second bamboo charcoal fiber layer are the same, and each accounts for one-fourth of the overall thickness.

[0008] As an optimization of the above technical solution, the first bamboo charcoal fiber layer is composed of first bamboo charcoal fiber strips and second bamboo charcoal fiber strips, and the first bamboo charcoal fiber strips and the second bamboo charcoal fiber strips are arranged alternately vertically and horizontally.

[0009] As an optimization of the above technical solution, the second bamboo charcoal fiber layer is composed of third bamboo charcoal fiber strips and fourth bamboo charcoal fiber strips, and the third bamboo charcoal fiber strips and the fourth bamboo charcoal fiber strips are arranged alternately vertically and horizontally.

[0010] As an optimization of the above technical solution, the gaps between the first bamboo charcoal fiber strips and the second bamboo charcoal fiber strips do not correspond to the gaps between the third bamboo charcoal fiber strips and the fourth bamboo charcoal fiber strips.

[0011] As an optimization of the above technical solution, the thicknesses of the filter cotton and the nylon layer are the same, and each accounts for one-eighth of the overall thickness.

[0012] As an optimization of the above technical solution, a number of ventilation holes are provided on the surface of the filter cotton.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] By providing the first bamboo charcoal fiber layer and the second bamboo charcoal fiber layer, the present utility model enables good air permeability while performing filtration. Since the gaps of the first bamboo charcoal fiber layer do not correspond to those of the second bamboo charcoal fiber layer, the first bamboo charcoal fiber layer and the second bamboo charcoal fiber layer can complement each other as upper and lower layers during filtration, reducing the situation where part of the water resource flows out directly from the gaps without passing through the first bamboo charcoal fiber layer or the second bamboo charcoal fiber layer, thereby reducing the filtration effect. Moreover, by reducing the overall number of layers and the overall thickness, air can pass through better, reducing resistance and enabling better water resource flow for filtration, greatly increasing the air permeability of the device.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] As Figure 2 shown, the present invention provides a technical solution: a filter medium with good air permeability, including a nylon layer 1 and a hemp fiber layer 3. The bottom end of the nylon layer 1 is fixedly connected to a first bamboo charcoal fiber layer 2, and the first bamboo charcoal fiber layer 2 is fixedly connected to the hemp fiber layer 3. The bottom end of the hemp fiber layer 3 is fixedly connected to a second bamboo charcoal fiber layer 4, and the bottom end of the second bamboo charcoal fiber layer 4 is fixedly connected to a filter cotton 5. This structure has a good air permeability effect by setting breathable materials. As Figure 2 shown, the filter cotton 5 and the nylon layer 1 have the same thickness, and both account for one-eighth of the overall thickness. The first bamboo charcoal fiber layer 2, the hemp fiber layer 3, and the second bamboo charcoal fiber layer 4 have the same thickness, and each accounts for one-fourth of the overall thickness. This structure uses a reasonable distribution to reduce the overall thickness of the device, making it easier for air to penetrate the device, greatly increasing the practicality of the device.

[0022] As an implementation method in this embodiment, as Figure 3 shown, the first bamboo charcoal fiber layer 2 is composed of a first bamboo charcoal fiber strip 21 and a second bamboo charcoal fiber strip 22, and the first bamboo charcoal fiber strip 21 and the second bamboo charcoal fiber strip 22 are arranged alternately vertically and horizontally. The second bamboo charcoal fiber layer 4 is composed of a third bamboo charcoal fiber strip 41 and a fourth bamboo charcoal fiber strip 42, and the third bamboo charcoal fiber strip 41 and the fourth bamboo charcoal fiber strip 42 are arranged alternately vertically and horizontally. This structure allows there to be a certain gap in the device, reducing the resistance to air flow and increasing air permeability.

[0023] As an implementation method in this embodiment, as Figure 3 shown, the gaps between the first bamboo charcoal fiber strip 21 and the second bamboo charcoal fiber strip 22 do not correspond to the gaps between the third bamboo charcoal fiber strip 41 and the fourth bamboo charcoal fiber strip 42. This structure enables the first bamboo charcoal fiber layer 2 and the second bamboo charcoal fiber layer 4 to complement each other as upper and lower layers. During filtration, it can reduce the situation where some water resources flow out directly from the gaps without passing through the first bamboo charcoal fiber layer 2 or the second bamboo charcoal fiber layer 4, greatly increasing the filtration effect of the device.

[0024] As an implementation manner in this embodiment, as Figure 4 shown, a plurality of ventilation holes 51 are formed on the surface of the filter cotton 5, and this structure enables the air permeability of the device to be further increased, so that the device can filter better.

[0025] Working principle: When using this device for filtration, water resources enter the device from above. First, they are filtered through the nylon layer 1, and then enter the first bamboo charcoal fiber layer 2. The water resources passing through the first bamboo charcoal fiber strip 21 and the second bamboo charcoal fiber strip 22 usually pass through the hemp fiber layer 3 for filtration, and then enter the gaps of the second bamboo charcoal fiber layer 4. The water resources entering the gaps of the first bamboo charcoal fiber layer 2 will pass through the hemp fiber layer 3 for filtration, and then enter the third bamboo charcoal fiber strip 41 and the fourth bamboo charcoal fiber strip 42 for filtration. Finally, after passing through the filter cotton 5, the filtration is completed. At the same time, during the filtration process, due to the gaps distributed in the first bamboo charcoal fiber layer 2 and the second bamboo charcoal fiber layer 4 of the device, air can enter better, and the resistance is reduced, allowing air to flow better. Finally, through the ventilation holes 51, air can be discharged better, thus increasing the air permeability of the device, driving the flow of water resources, and greatly increasing the filtration efficiency of the device.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
