[0028] When treating fiber impurities in textile wastewater, small bubbles are generated by flotation method, so that the fiber impurities are attached to the small bubbles and float to the water surface, so that the fiber impurities in the textile wastewater can be separated and recovered. In the existing technology, the small bubbles attached to the fiber impurities and the waste liquid are usually separated by scraping or salvaging. This method can easily destroy the small bubbles, so that the fiber impurities enter the waste liquid again and mix with it, so that the efficiency of treating the fiber impurities in the textile waste liquid is low. In this embodiment, by setting a collection part, the collection part has two states, one is a retracted state, and the other is an expanded state. When the waste liquid is poured into the volume box 1 After the inside, the liquid surface of the waste liquid enters the rotating box 2, and the liquid level is at the collecting part. At this time, the collecting part is in a retracted state and is located below the liquid surface of the waste liquid, so that the container flotation device at the bottom of the volume box 1 starts to work, generating small bubbles, so that the fiber impurities in the textile waste liquid adhere to the small bubbles, and the rise of the small bubbles brings the fiber impurities above the liquid surface, and then the collecting part is expanded through the changing mechanism to form a ring-shaped collecting net, and the collecting part is moved upward by the displacement mechanism, so that the floating fiber impurities are collected. This method can reduce the damage to the small bubbles, thereby improving the efficiency of separating the fiber impurities in the textile waste liquid from the textile waste liquid.

The collecting sheet 14 on one side of the collecting part rotates on the rotating rod 15, and the two rollers 16 on this collecting sheet 14 are fixedly connected to the first annular seat 17 and the second annular seat 22 respectively. The collecting sheet 14 in the middle part of the collecting part slides in the first annular seat 17 and the second annular seat 22 respectively through the rollers 16 rotatably installed on the rotating rods 15 on both sides. The collecting sheet 14 on the other side of the collecting part, on one side, also cooperates with the rotating rod 15 and the roller 16 to slide in the first annular seat 17, and a driving unit is provided on the rotating rod 15 on the other side. The driving unit can drive the collecting sheet 14 to slide in the first annular seat 17 and the second annular seat 22, so that multiple collecting sheets are unfolded to form an arc-shaped collecting net, so that the floating fiber impurities can be collected and separated from the textile waste liquid.

A gear ring 11 is provided on the outer wall of the rotating box 2, and a swing motor 8 is fixedly installed on the outer wall of the volume box 1. A main gear 9 is fixedly installed on the output end of the swing motor 8. The main gear 9 and the gear ring 11 are designed to be engaged. When the container air flotation device at the bottom of the volume box 1 works, the small bubbles generated make the fiber impurities in the textile waste liquid float to the liquid surface, and then the operation of the swing motor 8 drives the rotation of the rotating box 2. The rotating box 2 is connected by a plurality of connecting rods 20 It is fixedly connected to the internal rotating plate 25, thereby driving the rotating plate 25 to rotate synchronously. During the rotation of the rotating plate 25, the limiting groove 27 on the rotating plate 25 will be magnetically connected with the limiting block 29 to form a snap connection, thereby driving the multiple collecting sheets 14 to rotate and displace, thereby forming an annular collecting net. This process will be completed at the smooth part of the thread groove 13. When the rotating box 2 is continuously operated by the swing motor 8, the screw block 18 enters the thread groove 13, and the outer wall of the annular column 19 is provided with a vertical groove 24. The limiting block 23 fixedly installed inside the second annular seat 22 is designed to be snapped with the vertical groove 24, so that under the cooperation of the thread groove 13 and the vertical groove 24, the first annular seat 17 and the second annular seat 22 are synchronously displaced upward, so that the unfolded annular collecting net is displaced upward, so that the floating fiber impurities can be collected. When the collection is completed, the annular collecting net is displaced downward under the action of the swing motor 8, so that the multiple collecting sheets 14 can be folded and fitted, so that the floating fiber impurities can be collected and separated next time.

[0032] Among them, a more preferred embodiment is that an auger cover 21 is provided inside the volume box 1, and the bottom of the auger cover 21 is fixedly connected to the inner bottom of the volume box 1 through a plurality of first connecting rods, and the top of the auger cover 21 is fixedly connected to the bottom of the annular column 19 through a plurality of second connecting rods, and the inner rotation of the auger cover 21 is provided with a threaded groove 13, and the bottom of the volume box 1 is fixedly provided with a servo motor 12, and the output end of the servo motor 12 is fixedly connected to the auger 34, and the bottom of the auger cover 21 is fixedly connected to the bottom of the volume box 1 through a plurality of first connecting rods, and the top of the auger cover 21 is connected to the annular column 19 through a plurality of second connecting rods. The column 19 is fixedly connected, and each time the waste liquid is injected into the volume box 1, the height is within the rotating box 2, so that the waste liquid in the volume box 1 forms a circulation passage through the auger cover 21. Under the action of the auger 34, together with the servo motor 12, the waste liquid in the volume box 1 circulates, and under the action of the container flotation device set at the bottom of the volume box 1, the fiber impurities in the waste liquid can better contact with the small bubbles, thereby adhering to the small bubbles, and then floating to the liquid surface of the waste liquid, and the fiber impurities in the textile waste liquid can be separated from the textile waste liquid through the upward movement of the annular collecting net.

[0033] Among the more preferred embodiments, an assembly plate 32 is rotatably installed on the top of the annular column 19, and a plurality of semi-arc sweeping plates 4 and arc rods 6 are installed in an array on the circumferential outer wall of the assembly plate 32. The semi-arc sweeping plates 4 and the arc rods 6 are designed to be alternately distributed, and a pressure roller 5 is rotatably installed on the end of the arc rod 6. A collecting plate 33 is provided on the top of the rotating box 2, and a plurality of L-shaped rods 7 are installed in an array at the bottom of the collecting plate 33. The ends of the L-shaped rods 7 are fixedly connected to the outer wall of the volume box 1, and a collecting cover 3 is provided on the top of the collecting plate 33, and a collecting cover 3 is formed between the collecting cover 3 and the collecting plate 33. Space, when the annular collecting net collects and separates the fiber impurities floating on the textile waste liquid, under the action of the servo motor 12, the assembly plate 32 is driven to rotate, thereby driving the semi-arc sweeping plate 4 and the arc rod 6 fixedly installed on the circumferential outer wall of the assembly plate 32 to rotate, and under the rotation of the semi-arc sweeping plate 4, the fiber impurities collected on the arc collecting net enter the collecting space, and the pressing roller 5 rotating at the end of the arc rod 6 squeezes the collected fiber impurities, so that the moisture in the fiber impurities can be squeezed out, so that the fiber impurities can be better collected.

[0034] Among them, the more preferred embodiment is that the rotating connection between the rotating box 2 and the collecting cover 3 is filled with a sealing ring, and the top slide groove of the rotating box 2 and the bottom of the collecting cover 3 are installed with an annular slide bar, and the cross-sections of the slide groove and the annular slide bar are both dovetail-shaped. Through the dovetail-shaped design of the cross-section of the slide groove and the annular slide bar, and the cooperation with the sealing ring, when the rotating box 2 rotates on the volume box 1, the internal textile waste liquid will not seep to the outside, thereby improving the cleanliness of the equipment and preventing the seepage of the textile waste liquid from causing pollution.

[0035] Among them, the more preferred embodiment is that the collecting plate 33 and the collecting cover 3 are designed with threaded clamping, and the outer wall of the collecting plate 33 is provided with a flexible heating sheet. Through the design of the flexible heating bubble sheet, after the fiber impurities enter the collecting space, the moisture inside them is squeezed out by the pressure roller 5, and then dried by the flexible heating sheet, thereby improving the collection efficiency of fiber impurities in the textile waste liquid.

[0036] Among the more preferred embodiments, a semi-arc groove is provided at the bottom of the second annular seat 22, and the top of the limiting block 29 is designed as a dome. By designing the top of the limiting block 29 as a dome, when the screw block 18 enters the thread groove 13 from the smooth portion, the continuous rotation of the rotating plate 25 will cause the limiting groove 27 and the limiting block 29 to get stuck, so that the limiting block 29 slides into the column 28 under the action of the return spring 30. The dome design of the limiting block 29 can reduce the friction of the jam, so that the first annular seat 17 and the second annular seat 22 can move upward more smoothly.

[0037] Among them, a more preferred embodiment is that a controller is fixedly installed on the outer wall of the volume box 1, and the container flotation device and the swing motor 8 are electrically connected to the controller. The container flotation device starts working for a preset time under the control of the controller, and transmits an electrical signal to the swing motor 8 after stopping, and injects a certain amount of waste liquid into the volume box 1 through the external controller, so that the working time of the container flotation device can be controlled by the controller. After the time is reached, it stops working and drives the swing motor 8 to work, so that the collection part is expanded to form an annular collection net, and at the same time it is displaced upward to collect the floating fiber impurities.

[0038] Working principle: When the household textile printing and dyeing wastewater treatment and recycling device is used, the waste liquid is injected into the volume box 1, the container air flotation device works to generate small bubbles, and the servo motor 12 rotates the auger 34, so that the waste liquid inside the volume box 1 circulates, so that the fiber impurities in the waste liquid adhere to the small bubbles and float to the liquid surface. At this time, the controller stops the container air flotation device and starts the swing motor 8 to drive the rotating box 2 to rotate, and then the limiting groove 27 on the rotating plate 25 is displaced and magnetically connected with the limiting block 29 to form a snap connection, thereby driving the multiple collecting sheets 14 on the collecting part to unfold to form a ring-shaped collecting net. The threaded groove 13 and the screw block 18 cooperate with each other, and the vertical groove 24 opened on the annular column 19 cooperates with the limit block 23, so that the annular collecting net moves upward, so as to collect the floating fiber impurities. Under the action of the servo motor 12, a plurality of semi-arc sweeping plates 4 and pressure rollers 5 fixedly installed on the circumferential outer wall of the assembly plate 32 are driven, so that the fiber impurities on the arc collecting net enter the collecting space, and are squeezed at the same time, so that the residual moisture inside the fiber impurities is squeezed out, and the fiber impurities are dried by arranging a flexible heating plate on the collecting plate 33. Finally, the collecting cover 3 can be removed to further collect and process the fiber impurities in the collecting space.

[0039] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.
