The tank cover 2 is threadedly fixedly installed on the top of the tank body 1. Two groups of membrane separation devices are provided, and are respectively located on both sides of the tank body 1. A quick-release filter assembly is provided inside the tank cover 2. A circulation assembly is provided between the tank body 1, the tank cover 2 and the two membrane separation devices 3.

[0029] Example 1: The quick-release filter assembly includes a double-layer filter screen 4 and a fixing member 6. The fixing member 6 is fixed to the top of the inner wall of the tank cover 2. The fixing member 6 is composed of a connecting tube 601 and multiple connecting plates 602. The double-layer filter screen 4 is installed on the outside of the connecting tube 601.

[0030] In this embodiment, insertion rods 5 are provided on both sides of the inner wall of the feed port in the middle of the tank cover 2. The double-layer filter screen 4 is composed of two semicircular double-layer screens, and two symmetrically distributed first holes 401 are opened near the feed port in the middle of the tank cover 2. The insertion rods 5 are plugged into the first holes 401.

[0031] It should be noted that, by plugging the rod 5 into the first hole 401 , the double-layer filter 4 can be quickly fixed to prevent it from shifting or falling off during the filtering process, and it is also easy to remove for cleaning or replacement when needed.

[0032] In this embodiment, a first through hole is opened in the middle of the double-layer filter screen 4 , and two symmetrically distributed blocking blocks 402 are provided on the inner wall of the first through hole.

[0033] It should be noted that the design of the first through hole allows the stirring rod 7 to pass through so that the motor 8 can drive it to rotate. At the same time, the block 402 cooperates with the slot 603 in the fixing member 6, further enhancing the stability of the double-layer filter 4 and preventing it from shaking or falling off during the stirring process.

[0034] In this embodiment, one end of multiple connecting plates 602 is welded to the bottom of the connecting tube 601, and the top of the connecting plate 602 is fixed to the top of the inner wall of the tank cover 2 by bolts. Slots 603 are opened on both sides of the outside of the connecting tube 601, and the clamping block 402 is clamped with the slot 603.

[0035] In this embodiment, a motor 8 is provided on the top of the tank cover 2, and a protective shell 9 is installed on the outside of the motor 8. A plurality of circumferentially distributed support columns 10 are bolted between the protective shell 9 and the top of the tank cover 2. A stirring rod 7 is fixed to the output end of the motor 8, and a second through hole is opened in the middle of the connecting tube 601, through which the stirring rod 7 passes.

[0036] It should be noted that the design of the motor 8 and its protective shell 9 provides a power source for mixing the mother liquor and the pH regulator.

[0037] Example 2: The circulation component includes a first valve 11, a first pipe 12, a second pipe 13 and a hose 14.

One end of the second pipe 13 is fixed to the end of the hose 14, and the other end is fixedly connected to the side of the membrane separation device 3.

[0038] In this embodiment, the membrane separation device 3 is respectively provided with a raw liquid port and a concentrated liquid port at the lower and upper parts of the side facing the tank body 1, and a filtrate port is provided in the middle part of the other side. The first pipe 12 is installed between the first valve 11 and the raw liquid port, and the second pipe 13 is L-shaped, and one end thereof is fixedly connected to the concentrated liquid port.

[0039] In this embodiment, the second pipe 13 is also fixed to the side bolts of the tank cover 2. Two sets of support members 15 are provided on the top of the tank cover 2. One end of the support member 15 is fixed to the top bolts of the tank cover 2, and the other end is provided with an opening and clamped to the hose 14.

[0041] It should be noted that the design of the second valve 16 and the liquid outlet pipe allows the treated mother liquid or waste liquid to be discharged from the device when necessary.

[0042] Working principle:

[0043] After the condensate synthesis mother liquor and pH adjuster are poured into the feed port in the middle of the tank lid 2, they are filtered through the double-layer filter screen 4. The motor 8 then drives the stirring rod 7 to rotate, accelerating the mixing of the mother liquor and the pH adjuster. The mixed liquid is then transported to the membrane separation device 3 through the first valve 11 for further separation and purification. The solution is then re-transported to the feed port of the tank lid 2 through the second pipe 13 and the hose 14. Multiple cycles increase the purity of the mother liquor. During this period, a small amount of sample can be taken from the hose for testing to facilitate the addition of an appropriate amount of pH adjuster. When the device is finished, it is cleaned by first removing the bolts securing the second pipe 13 to the tank lid 2, then rotating the tank lid 2 to separate it from the tank body 1, and then removing the bolts between the connecting plate 602 and the top of the inner wall of the tank lid 2, between the output end of the motor 8 and the stirring rod 7, and between the support column 10 and the top of the tank lid 2. The tank lid 2, the fixing member 6, and the stirring rod 7 can then be removed. The double-layer filter screen 4 can then be removed and cleaned one by one.

[0044] Beneficial effects:

[0045] The condensate synthesis mother liquor recycling device, through the clever combination of the double-layer filter screen 4 and the fixing part 6 in the quick-release filter assembly built into the tank cover 2, is convenient for quick replacement and cleaning, ensuring the filtering effect and operating efficiency. The application of the membrane separation device 3 realizes the precise separation of the various components in the mother liquor, improves the purity of the mother liquor, and the design of the circulation component enables the mother liquor to gradually reach the ideal purity in multiple cycles, reducing resource waste. In addition, the stirring rod 7 driven by the motor 8 accelerates the mixing of the mother liquor and the pH regulator, further improving the processing efficiency.
