The present disclosure relates to a fabric decolorizing device.

The textile industry is facing the problem of excessive waste and waste disposal by consumers, and the waste of resources may cause global climate impact. For environmental sustainability and the elimination of waste, the world is responding to resource recycling to replace traditional practices such as disposal, landfill and incineration.

Generally speaking, discarded fabrics may come in various colors and need to be decolorized before they can be reused. For example, waste fabrics can be soaked in a container containing decolorizing liquid for decolorization, but the decolorization rate is slow, and the decolorizing liquid will affect the decolorization effect after absorbing the color of the fabric, making it difficult to improve the whiteness of the fabric and affecting the quality of the fabric. Efficiency in recycling waste fabrics. In addition, a large amount of used decolorizing liquid cannot be recycled and reused to form waste liquid, which not only causes the waste of decoloring liquid, but also requires centralized treatment, which takes a long time to process the waste liquid, which is not conducive to the fabric recycling industry.

According to some embodiments of the present disclosure, a fabric decolorization device includes an outer cylinder, an inner cylinder, a first filtration system and a second filtration system. The outer cylinder has a circulation outlet and a circulation inlet. The outer cylinder is configured to contain the decolorizing fluid. The inner cylinder is rotatably disposed in the outer cylinder, and is at least partially located under the liquid level of the decolorizing liquid, and is configured to accommodate the fabric. The first filtration system is connected to the circulation outlet and configured to filter out solid matter. The second filtration system is connected to the first filtration system and the circulation inlet, and is configured to adsorb the dye from the fabric decolorization to the decolorization liquid.

In some embodiments, the filter element of the first filtration system is different from the filter element of the second filtration system.

In some embodiments, the filter element of the first filter system is a mesh filter element, and the filter element of the second filter system is an activated carbon filter element or an ion exchange resin filter element.

The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein should be interpreted accordingly.

FIG. 1 is a schematic diagram of a fabric decolorization device 100 according to an embodiment of the present disclosure. As shown in the figure, the fabric decolorization device 100 includes an outer cylinder 110, an inner cylinder 120, a first filter system 130 and a second filter system 140. The outer cylinder 110 has a circulation inlet 112 and a circulation outlet 114. The outer cylinder 110 can accommodate a decolorization liquid 210. The inner cylinder 120 is rotatably disposed in the outer cylinder 110 and is at least partially located below the liquid level of the decolorization liquid 210. The inner cylinder 120 is connected to the outer cylinder 110. In this embodiment, the inner cylinder 120 has a plurality of holes 122, and the diameter of the holes 122 is in the range of 1.5 mm to 2.5 mm. The inner cylinder 120 can accommodate fabric, so the fabric in the inner cylinder 120 can be immersed in the decolorizing liquid 210. In addition, the rotation axis of the inner cylinder 120 is horizontal, so that the inner cylinder 120 is placed horizontally in the outer cylinder 110. When the inner cylinder 120 rotates in the outer cylinder 110, the decolorizing liquid 210 and the fabric in the inner cylinder 120 can be stirred, so that the fabric and the decolorizing liquid 210 are mixed and the decolorizing liquid 210 and the fabric are contacted.

In addition, the first filter system 130 is connected to the circulation outlet 114 of the outer cylinder 110 , and the second filter system 140 is connected to the first filter system 130 and the circulation inlet 112 of the outer cylinder 110 . That is to say, the first filtration system 130 is located downstream of the circulation outlet 114 and upstream of the second filtration system 140 , and the second filtration system 140 is located downstream of the first filtration system 130 and upstream of the circulation inlet 112 .

FIG. 2 shows a three-dimensional view of the filter element 132 of the first filter system 130 of FIG. 1. FIG. 3 shows a three-dimensional view of the filter element 142 of the second filter system 140 of FIG. 1. Referring to FIG. 2 and FIG. 3 simultaneously, the filter element 132 of the first filter system 130 may be a mesh structure filter element configured to filter out solids in the decolorizing solution 210. The filter element 132 of the first filter system 130 is different from the filter element 142 of the second filter system 140. The filter element 142 of the second filter system 140 may be an activated carbon filter element or an ion exchange resin filter element configured to adsorb the dye decolorized from the fabric to the decolorizing solution 210.

Referring to FIG. 1, the outer cylinder 110 has a decolorizing liquid inlet 116 and a decolorizing liquid temporary storage tank 160. First, fresh decolorizing liquid 210 (original liquid) participating in the first circulation can be provided from the decolorizing liquid inlet 116, so that the liquid level of the decolorizing liquid 210 is higher than the bottom of the inner cylinder 120. The decolorizing liquid temporary storage tank 160 is located below the outer cylinder 110, and the decolorizing liquid 210 can be stored in the decolorizing liquid temporary storage tank 160. During the operation of the fabric decolorizing device 100, the decolorizing liquid 210 can be replenished from the decolorizing liquid temporary storage tank 160. The decolorizing liquid temporary storage tank 160 can temporarily collect or process the decolorizing liquid 210 and recycle it for reuse.

When the fabric decolorization device 100 is running, the decolorization process is carried out. The inner cylinder 120 can rotate in the outer cylinder 110 to decolor the dye of the fabric in the inner cylinder 120 into the decolorization liquid 210 . After the decolorizing liquid 210 flows out from the circulation outlet 114, it first passes through the mesh structure filter element of the first filtering system 130 to filter out impurities such as fabric lint and solid matter. Then, the decolorizing liquid 210 from which impurities are filtered passes through the activated carbon filter element or ion exchange resin filter element of the second filtration system 140, and the dye is adsorbed and decomposed by the active adsorbent, so that the decolorizing liquid 210 is decolorized and purified. Then, the decolorization liquid 210 enters the outer cylinder 110 through the circulation inlet 112, so that the decolorization liquid 210 that has passed through the first filtration system 130 and the second filtration system 140 is recovered and recycled. The fabric decolorization device 100 simultaneously completes the decolorization of the fabric and removes impurities and dyes in the decolorization liquid 210 through the above cycle process, maintaining the decolorization ability of the decolorization liquid 210 to achieve the effect of accelerating fabric decolorization, and almost no waste liquid is discharged, which is beneficial to environmental protection.

In some embodiments, the fabric decolorization device 100 further includes a sensing element 150 . The sensing element 150 is located downstream of the second filtration system 140 Upstream of the circulation inlet 112, it is configured to detect the decolorizing liquid 210 after passing through the second filtration system 140. The sensing element 150 can be used to determine whether decolorization is completed and whether the decolorization ability of the decolorization liquid 210 is saturated during the decolorization process, thereby effectively controlling the optimization of the decolorization process. For example, if the sensing element 150 detects that the decolorizing liquid 210 flowing through the first filtering system 130 and the second filtering system 140 is consistent with the incoming decolorizing liquid 210, the decolorizing end point is reached, and the fabric decolorizing device 100 can be stopped to take out the fabric. The hole 122 of the inner cylinder 120 can be used as a convection hole. Before taking out the fabric, the centrifugal rotation of the inner cylinder 120 can be used to achieve the dehydration effect of removing the liquid (such as the decolorizing liquid 210), so as to facilitate the removal of the decolored fabric.

Furthermore, the outer cylinder 110 has an opening 118 , and the inner cylinder 120 is located in the opening 118 of the outer cylinder 110 . The fabric decolorizing device 100 further includes a flip-up outer cover 170 . The flip-up outer cover 170 is pivotally connected to the edge of the opening 118 of the outer cylinder 110 and can open and close the opening 118 of the outer cylinder 110 . The opening 118 allows the user to put in and take out fabrics and observe the liquid level of the decolorizing liquid 210 . In this embodiment, the flip-up outer cover 170 is a flip-up automatic latch safety outer cover.

Figure 4 illustrates a perspective view of a fabric decolorizing device 100 according to an embodiment of the present disclosure. Figure 5 shows a perspective view of the fabric decoloring device 100 of Figure 4 from another perspective. Figures 4 and 5 can show the specific configuration of the fabric decolorization device 100 of the embodiment in Figure 1 . The fresh decolorizing liquid 210 (see Figure 1) participating in the first cycle can be provided from the decolorizing liquid inlet 116 along the direction D1. In addition, the used decolorizing liquid 210 can be provided from the decoloring liquid temporary storage tank 160 . The decolorizing liquid 210 can enter the pump P along the directions D2 and D3, and Enter the first filter system 130 and the second filter system 140 along the direction D4, and enter the outer cylinder 110 along the directions D5, D6, and D7. When the fabric decolorization device 100 is running, the decolorization process is carried out. The inner cylinder 120 can rotate in the outer cylinder 110 to decolor the dye of the fabric in the inner cylinder 120 into the decolorization liquid 210 . The decolorizing liquid 210 flows out from the circulation outlet 114 and flows to the pump P along the directions D8 and D2, and then passes through the mesh structure filter element of the first filtration system 130 and the activated carbon filter element or ion exchange resin filter element of the second filtration system 140 in sequence. The decolorizing liquid 210 is allowed to remove impurities and be decolorized and purified. Then, the decolorizing liquid 210 enters the circulation inlet 112 along the directions D5, D6, and D7, and returns to the outer cylinder 110 for recycling.

Specifically, since the outer cylinder 110 of the fabric decolorizing device 100 has a circulation outlet 114 and a circulation inlet 112, and the first filter system 130 is located downstream of the circulation outlet 114 and upstream of the second filter system 140, and the second filter system 140 is located downstream of the first filter system 130 and upstream of the circulation inlet 112, when During the decolorization process of the fabric in the inner cylinder 120, the decolorization liquid 210 (see FIG. 1 ) can flow out through the circulation outlet 114, and sequentially filter the solid matter through the first filtering system 130, and adsorb the dye from the fabric decolorization to the decolorization liquid 210 through the second filtering system 140, so that the filtered decolorization liquid 210 enters the outer cylinder 110 through the circulation inlet 112. In this way, the circulation of the decolorization liquid 210 can simultaneously complete the functions of fabric decolorization and dye removal, so that the decolorization liquid 210 can maintain its decolorization ability to achieve the effect of accelerating fabric decolorization. The fabric decolorization device 100 can improve the whiteness of the fabric and the efficiency of waste fabric recycling processing. The large amount of used decolorization liquid 210 can be recycled and reused, which can save the usage of decolorization liquid 210 and the time of waste liquid treatment, which is beneficial to the sustainable development of the fabric recycling industry.
