Description

Technical Field

[0001] The utility model relates to an RO membrane treatment and recycling device for printing and dyeing wastewater, in particular to an RO membrane treatment and recycling device for printing and dyeing wastewater, belonging to the technical field of printing and dyeing wastewater treatment. Background Art

[0002] Printing and dyeing wastewater is wastewater containing a variety of pollutants generated by the textile printing and dyeing industry during the production process. It has the characteristics of large water volume, high content of organic pollutants, high alkalinity, and large changes in water quality. Therefore, RO membrane treatment and reuse equipment will be used to treat the printing and dyeing wastewater and convert it into recyclable water. The RO membrane separates the solutes and water in the wastewater through high pressure, effectively removing pollutants such as salt.

[0003] A printing and dyeing wastewater membrane recycling device disclosed in the Chinese patent application publication CN218025639U facilitates the cleaning of the filter membrane used for printing and dyeing wastewater treatment, while ensuring the stable operation of the wastewater treatment during the cleaning process, thereby ensuring the stable operation of the printing and dyeing production.

[0004] However, in the process of implementing the technical solution of the above patent, the disassembly and assembly method of the RO membrane is relatively cumbersome. When the RO membrane treatment and reuse device is used to treat printing and dyeing wastewater, the RO membrane will be blocked during long-term use, resulting in a poor separation effect of solutes and water in the wastewater. The RO membrane needs to be cleaned and replaced regularly. The existing RO membrane is fixed in two sealing frames by squeezing the RO membrane with bolts. A plurality of bolts are provided on the sealing frames. In order to ensure uniformity of fixation and avoid gaps between the two sealing frames, a plurality of bolts need to be symmetrically cross-tightened and tightened in stages. The plurality of bolts are slowly turned multiple times. This fixing method is relatively cumbersome, resulting in a slow disassembly and assembly speed of the RO membrane. Utility Model Content

Four mounting plates 6 are fixedly connected to the outer surfaces of the two sealing covers 5. The mounting plates 6 are installed on the outer surfaces of the treatment boxes 1 by bolts. When the sealing covers 5 are installed, the sealing covers 5 and the mounting frame 21 can be sealed.

[0030] Please refer to Figure 1 and Figure 2 A water inlet pipe 7 is arranged outside the treatment box 1, and two symmetrical connecting branch pipes 8 are fixedly connected to the outer surface of the water inlet pipe 7. One end of the two connecting branch pipes 8 away from the water inlet pipe 7 is fixedly connected to the outer surface of the two treatment boxes 1 respectively, and electric valves are arranged on the two connecting branch pipes 8 to control whether the connecting branch pipes 8 can flow.

[0031] Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The two processing boxes 1 are each provided with a disassembly and assembly component 2, which includes a mounting frame 21, a replaceable RO membrane 22, a sealing frame 23, a movable frame 24 and four rotating shafts 25. The replaceable RO membrane 22 is adapted to the sealing frame 23. The outer surfaces of the four rotating shafts 25 are each fixedly connected with an eccentric wheel 26, the outer surfaces of the four eccentric wheels 26 are each fixedly connected with a connecting plate 28, and the four connecting plates 28 are each hinged to the outer surface of the movable frame 24. By moving the movable frame 24, the four eccentric wheels 26 can be rotated simultaneously.

[0032] Four top plates 27 are fixedly connected to the outer surface of the sealing frame 23. The four top plates 27 are respectively adapted to the four eccentric wheels 26. The outer surfaces of the four top plates 27 are fixedly connected to springs 29. One end of the four springs 29 away from the top plates 27 is fixedly connected to the outer surface of the mounting frame 21. The springs 29 are always in a compressed state, thereby ensuring that the top plates 27 can be tightly attached to the eccentric wheels 26.

[0033] Both ends of the four rotating shafts 25 are rotatably connected to support seats 210 . The multiple support seats 210 are fixedly connected to the outer surface of the installation frame 21 . The support seats 210 play a supporting role for the rotation of the rotating shafts 25 .

[0034] Four guide rods 211 are fixedly connected to the outer surface of the installation frame 21, and four sliding tubes 212 are fixedly connected to the outer surface of the sealing frame 23. The four sliding tubes 212 are respectively slidably connected to the outer surfaces of the four guide rods 211. The guide rods 211 and the sliding tubes 212 guide the movement of the sealing frame 23 relative to the installation frame 21.

[0035] The inner wall of the mounting frame 21 is slidably connected with two internally threaded anti-slipping sliders 213, and the mounting frame 21 is provided with two sliding grooves matched with the internally threaded anti-slipping sliders 213. The sliding of the internally threaded anti-slipping sliders 213 can facilitate the fastening bolts 214 to align with the internally threaded anti-slipping sliders 213. The inner walls of the two internally threaded anti-slipping sliders 213 are threadedly connected with fastening bolts 214, and the two fastening bolts 214 both penetrate the movable frame 24 and are matched with the movable frame 24. By penetrating the fastening bolts 214 and tightening them into the internally threaded anti-slipping sliders 213, the movable frame 24 can be fixed to prevent the movable frame 24 from being moved unintentionally.

[0036] Please refer to and Figure 2 The inner walls of the two processing boxes 1 are fixedly connected with two symmetrical sealing guide rails 4, and the inner walls of the four sealing guide rails 4 are slidably connected with sealing slides 3, and the sealing slides 3 are fixedly connected to the outer surface of the installation frame 21. The setting of the sealing slides 3 and the sealing guide rails 4 can ensure the sealing of the installation frame 21 and the processing box 1.

[0037] Working principle: after opening the sealing cover 5, take the installation frame 21 out of the processing box 1, then unscrew the fastening bolts 214 from the internal thread anti-slip slider 213, and pull the fastening bolts 214 out of the movable frame 24, and then move the movable frame 24. Under the connection of the connecting plate 28, the eccentric wheel 26 rotates, and under the elastic force of the compressed spring 29, the top plate 27 is close to the eccentric wheel 26, so that the top plate 27 approaches the rotating shaft 25. At this time, the sealing frame 23 is away from the installation frame 21, so that the replaceable RO membrane 22 is taken out therefrom, and the replaceable RO membrane 22 is cleaned or replaced and placed between the installation frame 21 and the sealing frame 23. The reverse operation can fix the replaceable RO membrane 22. The device can squeeze and fix the replaceable RO membrane 22 by the sealing frame 23 by moving the movable frame 24. The fixing process is relatively fast, thereby improving the disassembly and assembly rate of the replaceable RO membrane 22.
