Description

Technical Field

[0001] This utility model relates to the field of textile dyeing technology, and in particular to a dyeing device that allows for the recycling of dye liquor. Background Technology

[0002] When the dyeing equipment is working, the workers place the textiles in the container of the dye vat so that the dye solution in the container can dye the textiles. However, when dyeing textiles using this method, the dye solution in the container has poor fluidity, resulting in poor dyeing effect.

[0003] In related technologies, the dyeing apparatus also includes a circulation pipe. The inlet of the circulation pipe is connected to the lower end of the receiving tank, and the outlet of the circulation pipe is connected to the upper end of the receiving tank. This allows the circulation pipe to discharge the dye liquor from the lower end of the receiving tank into the upper end, thereby enhancing the flowability of the dye liquor in the receiving tank. However, because the dye liquor in the receiving tank flows from the inlet to the outlet of the circulation pipe, the dyeing effect on the side of the textile closer to the outlet is better than that on the side closer to the inlet, resulting in poor dyeing uniformity and thus a poor dyeing effect. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a dyeing device that allows for the recycling of dye liquor, which enables better dyeing results for textiles.

[0033] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0034] The following is for reference. Figures 1 to 5 A dyeing apparatus capable of recycling dye solution according to an embodiment of the present invention will be described in detail.

[0035] refer to Figure 1 and Figure 2 A dyeing apparatus according to an embodiment of the present invention includes a dyeing unit 100 and a power assembly 200. The dyeing unit 100 includes a dyeing vat 110, and a first outlet water pipe 120, a first return water pipe 130, a second outlet water pipe 140, and a second return water pipe 150 connecting the dyeing vat 110. The connection point between the first return water pipe 130 and the dyeing vat 110 is at a higher height than the connection point between the first outlet water pipe 120 and the dyeing vat 110; the connection point between the second return water pipe 150 and the dyeing vat 110 is at a lower height than the connection point between the dyeing vat 110 and the dyeing vat 110. The connection point between the second water outlet pipe 140 and the dyeing vat 110; the power assembly 200 is connected to the first water outlet pipe 120, the first water return pipe 130, the second water outlet pipe 140 and the second water return pipe 150, and can make the dye liquor in the dyeing unit 100 circulate sequentially between the dyeing vat 110, the first water outlet pipe 120 and the first water return pipe 130, or can make the dye liquor in the dyeing unit 100 circulate sequentially between the dyeing vat 110, the second water outlet pipe 140 and the second water return pipe 150.

[0036] During the operation of the dyeing apparatus of this application, each dyeing unit 100 stores dye liquor in its dyeing vat 110. The dye liquor in the dyeing vat 110 flows out of the dyeing vat 110 through the first outlet pipe 120, and under the action of the power component 200, the dye liquor flows from the first outlet pipe 120 into the first return pipe 130, and then flows back into the dyeing vat 110 through the first return pipe 130. Since the connection point between the first return pipe 130 and the dyeing vat 110 is located above the connection point between the first outlet pipe 120 and the dyeing vat 110, it is possible to achieve... The dye liquor in dyeing vat 110 flows from top to bottom. Furthermore, the dye liquor in dyeing vat 110 can also flow out of dyeing vat 110 through the second outlet pipe 140, and under the action of the power component 200, the dye liquor flows from the second outlet pipe 140 into the second return pipe 150, and then flows back into dyeing vat 110 through the second return pipe 150. Since the connection point between the second return pipe 150 and dyeing vat 110 is located below the connection point between the second outlet pipe 140 and dyeing vat 110, the dye liquor in dyeing vat 110 can flow from bottom to top. From the above working process, it can be seen that the dyeing device of this application can realize the conversion of the flow direction of the dye liquor in dyeing vat 110, thereby making the color of textiles dyed by this dyeing device more uniform and further improving the dyeing effect.

[0037] In a specific embodiment of this utility model, the connection point between the first outlet pipe 120 and the dyeing vat 110 is located at the bottom of the dyeing vat 110, the connection point between the first return pipe 130 and the dyeing vat 110 is located at the top of the wall of the dyeing vat 110, the connection point between the second outlet pipe 140 and the dyeing vat 110 is located at the middle of the wall of the dyeing vat 110, and the connection point between the second return pipe 150 and the dyeing vat 110 is located at the bottom of the dyeing vat 110. It is understood that by setting the connection point between the second outlet pipe 140 and the dyeing vat 110 at the middle of the wall of the dyeing vat 110, and ensuring that the connection point is always below the surface of the dye solution in the dyeing vat, the dye solution in the dyeing vat 110 can flow smoothly out of the dyeing vat 110 along the second outlet pipe 140.

[0038] In some embodiments of this utility model, an annular transfer chamber is provided inside the dyeing vat 110, and multiple water spray holes 110a are circumferentially spaced on the inner side of the dyeing vat 110. All water spray holes 110a are connected to the transfer chamber, and the first return water pipe 130 is connected to the transfer chamber. For example, as... Figure 3 and Figure 4 As shown, an annular transfer chamber is located at the top of the dyeing vat 110 wall, and multiple water spray holes 110a are spaced circumferentially on the inner side of the dyeing vat 110 wall. Each water spray hole 110a is connected to the transfer chamber, and the first return water pipe 130 is connected to the transfer chamber. It can be understood that, under the action of the power component 200, the dye liquor can enter the transfer chamber from the first return water pipe 130 and be sprayed into the dyeing vat 110 through the multiple water spray holes 110a connected to the transfer chamber. By spraying the dye liquor circumferentially into the dyeing vat 110, the flow of the dye liquor in the dyeing vat 110 is made more uniform.

[0039] In some embodiments, the first return water pipeline 130 includes a return water pipe 131 and a plurality of return water bypass pipes 132. One end of each return water bypass pipe 132 is connected to the outlet end of the return water pipe 131, and the other end of each return water bypass pipe 132 is connected to the transfer chamber. The plurality of connection points between the return water pipe 131 and the transfer chamber are distributed circumferentially along the dye vat 110. For example, as... Figure 5As shown, the first return water pipeline 130 includes a return water pipe 131 and two return water bypass pipes 132. The two return water bypass pipes 132 are symmetrically distributed on both sides of the return water pipe 131, and the connection points of the two return water bypass pipes 132 and the dyeing vat 110 are located on opposite sides of the dyeing vat 110. One end of each of the two return water bypass pipes 132 is connected to the outlet end of the return water pipe 131, and the other end of each of the two return water bypass pipes 132 is connected to the transfer chamber. It can be understood that when the dye liquor flows from the return water pipe 131 into the two return water bypass pipes 132 and from the two return water bypass pipes 132 into the transfer chamber, the two streams of dye liquor flow in the transfer chamber at similar flow rates and are sprayed out from the spray holes 110a connected to the transfer chamber. At this time, the flow rate of the dye liquor sprayed from each spray hole 110a is relatively uniform, thereby making the flow rate of the dye liquor in the dyeing vat 110 more consistent, resulting in a more uniform color during textile dyeing and improving the dyeing effect.

[0040] In some embodiments of this utility model, the second water outlet pipe 140 includes a water outlet pipe 141 and a plurality of water outlet bypass pipes 142. One end of each water outlet bypass pipe 142 is connected to the water inlet end of the water outlet pipe 141, and the other end of each water outlet bypass pipe 142 is connected to the dyeing vat 110. The plurality of connection points between the water outlet pipe 141 and the dyeing vat 110 are distributed at intervals along the circumference of the dyeing vat 110. For example, as... Figure 3 As shown, the first water outlet pipe 120 includes a water outlet pipe 141 and two water outlet bypass pipes 142. The two water outlet bypass pipes 142 are symmetrically distributed on both sides of the water outlet pipe 141. The connection points between the two water outlet bypass pipes 142 and the dyeing vat 110 are located on opposite sides of the dyeing vat 110. One end of the two water outlet bypass pipes 142 is connected to the dyeing vat 110, and the other end of the two water outlet bypass pipes 142 is connected to the water inlet end of the water outlet pipe 141. It can be understood that the dye liquor in the dyeing vat 110 can flow into the water outlet pipe 141 from the two water outlet bypass pipes 142, and then flow into the second return water pipe 131 through the water outlet pipe 141, making the flow of the dye liquor in the dyeing vat more uniform in the circumferential direction of the dyeing vat.

[0041] refer to Figure 1 and Figure 5 In some embodiments of this utility model, the power assembly 200 includes a water pump 210. The inlet end of the water pump 210 is connected to the first outlet pipe 120 and the second outlet pipe 140, and the outlet end of the water pump 210 is connected to the first return pipe 130 and the second return pipe 150. A first valve body 121 is provided on the first outlet pipe 120 to control the opening or closing of the first outlet pipe 120. A second valve body 133 is provided on the first return pipe 130 to control the opening or closing of the first return pipe 130. A third valve body 143 is provided on the second outlet pipe 140 to control the opening or closing of the second outlet pipe 140. A fourth valve body 151 is provided on the second return pipe 150 to control the opening or closing of the second return pipe 150.

[0042] Understandably, when the first valve body 121 and the second valve body 133 are in the open state, and the third valve body 143 and the fourth valve body 151 are in the closed state, the dye liquor in the dyeing vat 110 flows into the first outlet pipe 120. Under the action of the water pump 210, the dye liquor is transported to the first return pipe 130, and then the dye liquor is discharged from the first return pipe 130 and re-enters the dyeing vat 110. When the first valve body 121 and the second valve body 133 are in the closed state, and the third valve body 143 and the fourth valve body 151 are in the open state, the dye liquor in the dyeing vat 110 flows into the second outlet pipe 140. Under the action of the water pump 210, the dye liquor is transported to the second return pipe 150, and then discharged from the second return pipe 150 and re-enters the dyeing vat 110.

[0043] In a specific embodiment of this utility model, the second valve body 133 is disposed on the return water pipe 131 and is used to control the opening or closing of the return water pipe 131; the third valve body 143 is disposed on the outlet water pipe 141 and is used to control the opening or closing of the outlet water pipe 141.

[0044] refer to Figure 1 , Figure 2 and Figure 5 In one embodiment, the dyeing apparatus includes multiple dyeing units 100, and the power assembly 200 further includes a first main pipeline 220 and a second main pipeline 230. The first main pipeline 220 is connected to the inlet end of the water pump 210, and the second main pipeline 230 is connected to the outlet end of the water pump 210. In the same dyeing unit 100, the outlet ends of the first outlet pipeline 120 and the second outlet pipeline 140 are both connected to the first main pipeline 220, and the inlet ends of the first return pipeline 130 and the second return pipeline 150 are both connected to the second main pipeline 230.

[0045] It should be understood that after the dyeing solution in the dyeing device circulates in a single dyeing unit 100 to dye the textiles placed in the single dyeing unit 100, it can also transfer the dyeing solution in the dyeing unit 100 to another dyeing unit 100 to dye the textiles placed in the other dyeing unit 100.

[0046] Understandably, when the dye liquor needs to circulate within a single dyeing unit 100, the first valve 121 and the second valve 133 in that dyeing unit 100 are opened, the third valve 143 and the fourth valve 151 in that dyeing unit 100 are closed, and all valves in other dyeing units 100 are closed. At this time, in that dyeing unit 100, the dye liquor in the dye tank 110 can flow out from the first outlet pipe 120 and enter the first main pipe 220. Then, the water pump 210 transports the dye liquor to the second main pipe 230, and then it enters the dye tank 110 from the outlet of the first return pipe 130, thereby realizing the circulation of the dye liquor in the dyeing unit 100. The dye liquor in dyeing vat 110 flows from top to bottom. By opening the third valve body 143 and the fourth valve body 151 in this dyeing unit 100, closing the first valve body 121 and the second valve body 133 in this dyeing unit 100, and closing each valve body in other dyeing units 100, the dye liquor in dyeing vat 110 flows out from the second outlet pipe 140 and enters the first main pipe 220. Then, the dye liquor is transported to the second main pipe 230 by the water pump 210, and finally enters the dyeing vat 110 again through the second return pipe 150, thereby realizing the flow of dye liquor in dyeing vat 110 of dyeing unit 100 from bottom to top.

[0047] It is understandable that when the dye solution needs to be transferred between two staining units 100, for example, as referenced... Figure 1The three dyeing units 100 are named sequentially as the first dyeing unit, the second dyeing unit, and the third dyeing unit according to their arrangement direction, with one dyeing unit 100 designated as the first dyeing unit and the other as the second dyeing unit. When the dye solution in the dyeing tank 110 of the first dyeing unit needs to be transferred to the dyeing tank 110 of the second dyeing unit, by opening the first valve body 121 in the first dyeing unit and the second valve body 133 in the second dyeing unit, and closing the remaining valve bodies, the dye solution in the dyeing tank 110 of the first dyeing unit can enter the first main pipeline 220 through the first water outlet pipe 120 of the first dyeing unit, and then be transported to the second main pipeline by the water pump 210. 230, then flows into the dyeing vat 110 of the second dyeing unit through the first return water pipe 130 in the second dyeing unit; when the dye liquor in the dyeing vat 110 of the second dyeing unit needs to be transferred to the dyeing vat 110 of the first dyeing unit, by opening the first valve body 121 and the second valve body 133 in the second dyeing unit and closing the other valve bodies, the dye liquor in the dyeing vat 110 of the second dyeing unit can enter the first main pipe 220 through the first outlet water pipe 120 of the second dyeing unit, and then be transported to the second main pipe 230 by the water pump 210, and then flow into the dyeing vat 110 of the first dyeing unit through the first return water pipe 130 in the first dyeing unit. In summary, the dyeing device of this utility model can realize the circulation of dye liquor in the dyeing vats 110 of any two dyeing units 100, thereby realizing the recycling of dye liquor.

[0048] refer to Figure 1 and Figure 2 In some embodiments of this utility model, a heating structure 300 for heating the dye solution is also included. The heating structure 300 is disposed on the second main pipeline 230, and the water inlet of the heating structure 300 is connected to the water outlet of the water pump 210. The first return water pipeline 130 and the second return water pipeline 150 in each dyeing unit 100 are both connected to the water outlet of the heating structure 300.

[0049] It is understandable that in a single dyeing unit 100, when the first valve body 121 and the second valve body 133 are in the open state, and the third valve body 143 and the fourth valve body 151 are in the closed state, the dye liquor in the dyeing tank 110 can flow sequentially into the first outlet pipe 120 and the first main pipe 220, and be transported to the second main pipe 230 by the water pump 210. After being heated by the heating structure 300 set on the second main pipe 230, the dye liquor flows into the first return pipe 130 and finally re-enters the dyeing tank 110. When the first valve body 121 and the second valve body 133 are in the closed state, and the third valve body 143 and the fourth valve body 151 are in the open state, the dye liquor in the dyeing tank 110 enters the second outlet pipe 140, is then output by the water pump 210 and passes through the second main pipe 230, is then heated by the heating structure 300 and flows into the second return pipe 150, and finally re-enters the dyeing tank 110. By setting a heating structure 300 on the second main pipeline 230, the temperature of the dye liquor is maintained at a certain value to ensure the dyeing quality of the textiles.

[0050] refer to Figure 1 In some embodiments, a temperature detection structure 111 is provided on the dyeing vat 110, which is used to detect the temperature of the dyeing solution in the dyeing vat 110.

[0051] refer to Figure 1 In one embodiment, the dyeing apparatus further includes a water supply line 400, which is connected to a second water outlet line 140 and is capable of supplying liquid to the dyeing vat 110.

[0052] For example, the water supply pipeline 400 includes a water supply pipe and a fifth valve body. The water supply pipe is connected to the second water outlet pipeline 140. The inlet end of the water supply pipe is connected to the water source. The fifth valve body is installed on the inlet end of the water supply pipe and is used to control the opening or closing of the water supply pipe.

[0053] refer to Figure 1 In one embodiment, the dyeing apparatus further includes a drain pipe 500, which is connected to the first water outlet pipe 120 and is used to discharge the dyeing liquid in the dyeing vat 110.

[0054] For example, the sewage pipe 500 includes a sewage pipe and a sixth valve body. The sewage pipe is connected to the first water outlet pipe 120, and the water outlet end of the sewage pipe is connected to the sewage tank. The sixth valve body is installed on the sewage pipe and is used to control the opening or closing of the sewage pipe.

[0055] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
