Description

Technical Field

[0001] The invention belongs to the technical field of textile equipment, and more specifically, particularly relates to a dyeing and finishing liquid recovery device. Background Art

[0002] Dyeing and finishing liquid is a general term for various chemical solutions used in the dyeing and finishing process of textiles. The composition and properties of dyeing and finishing liquid will vary according to the specific dyeing and finishing process and requirements. Common ingredients include dyes, auxiliaries (such as leveling agents, fixing agents, softeners, etc.), acids, alkalis, salts, etc., and their functions are to give textiles the desired color, feel, functionality (such as waterproof, wrinkle-proof, etc.) and to improve the quality and performance of textiles. Different types of dyeing and finishing liquids are suitable for different fiber materials (such as cotton, linen, silk, wool, chemical fiber, etc.) and dyeing and finishing processes (such as dyeing, printing, finishing, etc.). In use, the dyeing and finishing liquid recovery device usually applies the following technologies:

[0003] 1. Filtration system: used to remove solid impurities and suspended matter in dyeing and finishing liquid;

[0004] 2. Chemical treatment unit: may include adding chemicals to neutralize pH, precipitate certain components, etc.;

[0005] 3. Separation device: such as centrifuge, membrane separator, etc., used to separate different components in dyeing and finishing liquid;

When the dyeing and finishing liquid impacts the diverter strip 27, a slight vibration will be generated. At this time, the diverter strip 27 will drive the filter frame 26 to move downward on the positioning column 23. At this time, the filter frame 26 will apply an extrusion force to the four slip rings 24. Under the action of this force, the four first springs 25 will be compressed to generate elastic force, so that the filter frame 26 can maintain a slight vibration when the dyeing and finishing liquid is injected, and then it can assist in shaking the filtered impurities, so that it is not easy to adhere to the equipment, further reducing the risk of blockage in the filtration process, and improving the filtration efficiency and continuity;

[0044] Two groups of jacks 42 are provided on the two collection boxes 41, and two groups of positioning rods 37 are respectively inserted into the two groups of jacks 42. Second filter screens 43 are fixedly installed on the opposite ends of the two collection boxes 41. A sliding column 44 is slidably installed inside the circular hole 28. A scraper is installed on a section of the sliding column 44 immersed in the drainage plate 15. A fixed plate 45 is fixedly installed on the upper end of the sliding column 44, and a third spring 46 is fixedly installed on the lower end of the fixed plate 45. One end of the third spring 46 away from the fixed plate 45 is fixedly installed on the diverter strip 27. When in use, the suction pipe 19 can be placed in the dyeing and finishing liquid first, and then the water pump 17 can be started. Under the action of the water pump 17, the dyeing and finishing liquid will be drawn out, and then it will be drained. The dyeing and finishing liquid will fall onto the diverter strip 27, and will be divided into two parts through the diverter strip 27 and flow into the two first filter screens 29 respectively. At this time, one part of the dyeing and finishing liquid will be filtered through the first filter screen 29 and discharged into the inner plate 21, and the other part will fall into the collecting box 41 through the leakage port 31, and then be filtered through the second filter screen 43 on the collecting box 41 and discharged into the inner plate 21, thereby completing the filtration and recovery of the dyeing and finishing liquid; and through the design of the collecting box 41 and the second filter screen 43, the impurities generated during the filtration process can be pre-stored in the collecting box 41, so that the equipment can continuously filter the dyeing and finishing liquid, thereby extending the cleaning cycle and improving the recovery efficiency.

[0045] Working principle:

[0046] In the first step, when in use, the suction tube 19 can be placed in the dyeing and finishing liquid, and then the water pump 17 can be started. Under the action of the water pump 17, the dyeing and finishing liquid will be sucked out, and then sprayed out through the drainage head 18. At this time, the dyeing and finishing liquid will fall onto the diverter strip 27, and the drainage through the diverter strip 27 will be divided into two parts and flow into the two first filter screens 29 respectively. At this time, a part of the dyeing and finishing liquid will be filtered through the first filter screen 29 and discharged into the inner plate 21, and the other part will fall into the collection box 41 through the leakage port 31, and then be filtered through the second filter screen 43 on the collection box 41 and discharged into the inner plate 21, and then can be discharged through the discharge port 14 and the drainage plate 15 for collection and use, thereby completing the filtration and recovery of the dyeing and finishing liquid; and through the design of the collection box 41 and the second filter screen 43, the impurities generated during the filtration process can be pre-stored in the collection box 41, so that the equipment can continuously filter the dyeing and finishing liquid, extending the cleaning cycle, thereby improving the recovery efficiency;

[0047] In the second step, when impurities are generated during filtration, part of the impurities will remain on the first filter screen 29, and the other part will flow into the collection box 41 under the flow of the dyeing and finishing liquid. The part of the impurities remaining on the first filter screen 29 will also fall into the collection box 41 under the repeated drainage of the dyeing and finishing liquid, and the collection is completed, so that the device is not easy to be blocked during use, thereby maintaining the filtering and recovery effect of the device;

[0048] The third step is to pull the limit plate 33 upwards during installation. The movement of the limit plate 33 will drive the second spring 35 to stretch. At this time, the two collection boxes 41 can be inserted into the two positioning rods 37 respectively, and then the limit plate 33 can be loosened. At this time, the second spring 35 will drive the limit plate 33 to reset and then insert it into the limit groove 38 to complete the limit of the collection box 41. Then, the positioning holes on the filter frame 26 can be inserted into the four positioning columns 23, and then the box cover 16 is clamped on the recovery box 11 to complete the installation of the equipment, so that the overall installation and disassembly of the equipment is more convenient when in use;

[0049] Step 4: When the dyeing and finishing liquid impacts the diverter strip 27, it will produce a slight vibration. At this time, the diverter strip 27 will drive the filter frame 26 to move downward on the positioning column 23. At this time, the filter frame 26 will apply an extrusion force to the four slip rings 24. Under the action of this force, the four first springs 25 will be compressed to generate elastic force, so that the filter frame 26 can maintain a slight vibration when the dyeing and finishing liquid is injected, and then it can assist in shaking the filtered impurities, so that it is not easy to adhere to the equipment, further reducing the risk of blockage in the filtration process and improving the filtration efficiency and continuity.

[0050] The fifth step is that when the drainage plate 15 is clogged after long-term use, the fixed plate 45 can be pulled upward. The fixed plate 45 will drive the slide post 44 to slide inside the drainage plate 15. At this time, the third spring 46 will also be stretched. Under the sliding of the slide post 44, the scraper will clear the clogged part inside the drainage plate 15 to ensure smooth flow.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
