Description

Technical Field

[0001] This utility model relates to the field of textile dyeing technology, and in particular to a device for recycling dyes from waste textiles. Background Technology

[0002] The reason why clothing and other textiles are so colorful is because the raw materials used to make them are dyed using dyeing pigments. For waste fabrics, we can decolorize them to obtain relatively clean fiber materials. These fiber materials can be reprocessed into raw materials for production such as fabrics and textile threads. This method not only saves costs but also conserves resources and protects the environment to a certain extent.

[0003] After old clothes are decolorized, the dyes mix with the decolorized wastewater. To prevent the wastewater from being discharged into nature and polluting the soil and groundwater, it needs to be purified before being discharged. However, treating this wastewater requires building a wastewater treatment plant, which is very costly.

[0004] Therefore, it is necessary to provide a device for decolorizing and recycling dyes from waste textiles to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a waste textile decolorization dye recovery device that can adsorb dye particles in wastewater, which can not only reduce pollutants in wastewater, but also recover dye particles in wastewater for reuse.

The adsorption assembly includes a tray, a plurality of adsorption cylinders mounted on the tray, and activated carbon placed in the cavity of each adsorption cylinder.

[0008] Preferably, the drain pipe includes a section of riser, which is made of a transparent material.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0023] First embodiment:

[0024] like Figure 1-4 As shown, the waste textile decolorization dye recovery device provided by this utility model includes: a base plate 101, a support platform 102 on the upper end of the base plate 101, the base plate 101 and the support platform 102 forming the skeleton of the device, and the remaining components of the device are installed on the skeleton formed by the two. A reaction tank 104 is installed on the support platform 102. The reaction tank 104 is cylindrical with a cavity inner wall, a sealed lower end and an open upper end. The reaction tank 104 is a storage and adsorption container for dye wastewater. A discharge pipe 105 is provided at the lower end of the reaction tank 104, and the upper opening of the discharge pipe 105 is connected to the reaction tank 104. The internal cavity of reaction chamber 104 has a discharge pipe 105, the other end of which is installed on the inlet of pump 107. The outlet of pump 107 is connected to discharge pipe 106, which is connected back to reaction chamber 104. One side of discharge pipe 105 is connected to drain pipe 108 via a T-junction. A valve is provided at the opening of drain pipe 108. A top cover 116 is installed at the upper opening of reaction chamber 104. The top cover 116 has a through hole. An adsorption assembly 109 is provided inside reaction chamber 104. The adsorption assembly 109 is placed on a ring 118 located on the inner wall of reaction chamber 104. The structure of adsorption assembly 109 is as follows. Figure 3-4As shown, the adsorption assembly 109 includes a tray 110, on which several adsorption cylinders 111 are mounted. Activated carbon is placed inside the cavity of each adsorption cylinder 111. In use, the top cover 116 at the upper end of the reaction chamber 104 is first opened, and dye wastewater is added to the reaction chamber 104. The dye wastewater enters the reaction chamber 104 and contacts the adsorption assembly. During this process, the dye wastewater is first blocked by the tray 110. Both the upper and lower ends of the adsorption cylinders 111 have through holes. Therefore, the dye wastewater first enters the interior of the adsorption cylinder 111 through the upper through hole and contacts the activated carbon. The activated carbon adsorbs some of the dye particles in the dye wastewater and finally discharges from the lower through hole of the adsorption cylinder 111 and enters the reaction chamber 104 at the lower end of the adsorption assembly 109. The pump 107 is then started, drawing the dye wastewater from the discharge pipe 105, through the inlet pipe 106, and finally back into the reaction chamber 104. This cycle is repeated several times. The activated carbon is used to fully absorb the dye particles in the dye wastewater. It is important to note that the activated carbon here is a material for adsorbing dye particles. In addition, for different types of dyes, substances such as resins that can adsorb corresponding dye particles in the dye wastewater can also be used. The valve on the drain pipe 108 is opened to allow the dye wastewater after adsorption to be discharged from the device through the drain pipe 108. Finally, ethanol is added from the opening at the top of the reaction tank 104. The flow process of ethanol in the reaction tank 104 is the same as that of dye wastewater, which will not be described in detail here. The difference between the two is that when ethanol passes through the adsorption cylinder 111 and comes into contact with the activated carbon inside, the ethanol dissolves the dye particles adsorbed by the activated carbon, that is, the dye particles are desorbed. After circulating under the action of the pump 107, the ethanol solution containing dissolved dye particles is discharged from the drain pipe 108. Finally, the ethanol is evaporated by means of evaporation, thereby obtaining the dye particles.

[0025] By setting up pumps 107 and other related components, the dye wastewater is circulated and adsorbed by the filter component 109. Compared with the existing method of putting dye wastewater into a sewage treatment plant for treatment, the pollution of dye wastewater after adsorbing dye particles is reduced, and it can be used for other water use in the dye factory. At the same time, it reduces the cost of directly treating dye wastewater in the sewage treatment plant, and can also recover some dye particles.

[0026] Second embodiment:

[0027] like Figure 2 As shown, the drain pipe 108 includes a section of riser 114, which is made of transparent material. The color of the dye wastewater will lighten after being adsorbed by activated carbon. Similarly, the color will darken after the dye particles in the activated carbon are dissolved by ethanol.

[0028] By observing the color of the liquid in the transparent riser 114, the saturation of the adsorbed or dissolved dye particles can be determined, thereby timely determining the sufficiency of adsorption and desorption.

[0029] Third embodiment:

[0030] like Figure 1-4 As shown, the reaction chamber 104 has a feeding port 115 on its side wall. The tray 110 is located below the feeding port 115. The tray 110 is equipped with an installation cylinder 113. The adsorption cylinder 111 can be detached and placed in the installation cylinder 113. After long-term adsorption and desorption, the adsorption capacity of activated carbon for dye particles is reduced. At this time, new activated carbon should be replaced in time. When replacing, first open the cover on the feeding port 115, then take the adsorption cylinder 111 out of the installation cylinder 113, and then place the adsorption cylinder 111 containing new activated carbon into the installation cylinder 113.

[0031] The addition port 115 facilitates the replacement of the failed activated carbon in the adsorption cylinder 111 from that location.

[0032] Fourth embodiment:

[0033] like Figure 3-4 As shown, the bottom of the adsorption cylinder 111 is provided with a through hole, and the upper opening is threadedly connected to the sealing cap 112. The sealing cap 112 is also provided with several through holes. After opening the sealing cap 112, the activated carbon in the adsorption cylinder 111 is taken out, new activated carbon is put in, and the sealing cap 112 is put back on. This completes the replacement of the adsorption cylinder 111.

[0034] By setting an openable adsorption cylinder 111, the effect of multiple uses can be achieved, reducing production costs.

[0035] Fifth embodiment:

[0036] like Figure 1 As shown, the upper end of the support platform 102 is provided with a bracket 103, which has a certain height. The reaction box 104 is fixed on the bracket 103, thereby increasing the connection stability of the reaction box 104. Secondly, the lower end of the base plate 101 is provided with four casters 117 to facilitate the movement of the device.

[0037] Working principle: Dye particles in dye wastewater are adsorbed using adsorbent materials such as ethanol. Then, the dye particles are released from the adsorbent material through a desorption process. When the dye wastewater comes into contact with activated carbon, the pigment molecules are adsorbed into the pores of the activated carbon under the action of van der Waals forces on the surface of the activated carbon. Afterward, by using a suitable desorbent, the dye particles can be desorbed from the activated carbon. Finally, the desorbent and pigment are separated by evaporation or other methods to obtain the dye particles.

[0038] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
