Description

Technical Field

[0001] This utility model relates to the field of liquid collection and storage technology, and in particular to a perfluoropolyether liquid waste storage device. Background Technology

[0002] Polyphenylene sulfide (PPS) resin, or simply polyether, is a new type of high-performance thermoplastic resin with advantages such as high mechanical strength, high temperature resistance, chemical corrosion resistance, flame retardancy, good thermal stability, and excellent electrical properties. It is widely used as a structural polymer material. The initial form of PPS obtained during production contains a large amount of low molecular weight polymers, solvent NMP, and inorganic salts. It needs to be repeatedly washed with a large amount of washing water to remove impurities before it can meet the requirements of downstream use. Currently, the most common method of impurity removal is centrifugation, followed by washing with a large amount of hot water. This process is repeated until the PPS product meets the quality requirements. During the washing and centrifugation process, a large amount of waste liquid is generated that needs to be collected and discharged for treatment.

[0003] Large quantities of waste liquid contain solid polyphenylene sulfide (PPS) particles. If these are not recycled and directly processed, they can easily clog downstream equipment and waste products. Currently, the main solution is to install a filter screen inside the collection tank to filter the PPS particles in the waste liquid. However, after filtering the solid particles, they accumulate on the surface of the filter screen, reducing its filtration efficiency. When there are many solid particles on the filter screen, workers need to clean them before they can continue filtering the waste liquid. This makes it impossible to continuously filter the solid particles in the waste liquid. The need to clean the filter screen not only increases the labor intensity of workers but also reduces the efficiency of the filter screen in filtering the waste liquid. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a perfluoropolyether liquid waste storage device that can solve the problem that workers need to clean off solid particles before they can continue to filter the waste liquid, which makes it impossible to continuously filter solid particles in the waste liquid. The need for workers to clean the filter screen not only increases the labor intensity of workers, but also reduces the efficiency of the filter screen in filtering the waste liquid.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a perfluoropolyether liquid waste storage device, comprising a mounting base plate and a polyether liquid waste filtration device; two support frames are fixedly connected to the top of the mounting base plate, and a circular screening cylinder is fixedly connected to the upper end of the two support frames; the polyether liquid waste filtration device includes a rotating shaft, a connecting shaft, a spiral scraper, a second support frame, and a drive motor; the rotating shaft is rotatably connected inside the circular screening cylinder; the connecting shaft is linearly and equidistantly fixedly connected to the surface of the rotating shaft; the spiral scraper is fixedly connected to the surface of the connecting shaft; the surface of the spiral scraper contacts the inner wall of the circular screening cylinder; and the right end of the rotating shaft extends to the outside of the circular screening cylinder.

[0011] Preferably, a solid storage box is fixedly connected to the left end of the mounting base plate, and the solid storage box is located directly below the solid discharge cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1.

[0024] Please see Figure 1-4This utility model provides a technical solution: a perfluoropolyether liquid waste storage device, including a mounting base plate 1 and a polyether liquid waste filtration device. Two support frames 2 are fixedly connected to the top of the mounting base plate 1. A circular screening cylinder 3 is fixedly connected to the upper end of the two support frames 2. A conical feed pipe 4 is fixedly installed on the top of the circular screening cylinder 3. A solid discharge cylinder 5 is fixedly connected to the left end of the circular screening cylinder 3. The polyether liquid waste filtration device includes a rotating shaft 6, a connecting shaft 7, a spiral scraper 8, a second support frame 9, and a drive motor 10. The rotating shaft 6 is rotatably connected to the inside of the circular screening cylinder 3. The connecting shaft 7 is linearly and equidistantly fixed to the surface of the rotating shaft 6. The spiral scraper 8 is fixedly connected to the surface of the connecting shaft 7. The surface of the spiral scraper 8 contacts the inner wall of the circular screening cylinder 3. The right end of the rotating shaft 6 extends to the outside of the circular screening cylinder 3. The second support frame 9 is fixedly connected to the top of the mounting base plate 1. The drive motor 10 is fixedly installed on the upper end of the second support frame 9. The output end of the drive motor 10 is fixedly connected to the right end of the rotating shaft 6.

[0025] A trapezoidal receiving hopper 11 is fixedly connected to the inner side of the two support frames 2. A drain pipe 12 is fixedly connected to the bottom of the trapezoidal receiving hopper 11. A waste liquid storage tank 13 is fixedly connected to the top of the mounting base plate 1. The lower end of the drain pipe 12 extends into the interior of the waste liquid storage tank 13. A discharge pipe 14 is fixedly installed at the rear end of the waste liquid storage tank 13. A valve 15 is installed at the end of the discharge pipe 14 away from the waste liquid storage tank 13. A solid storage tank 16 is fixedly connected to the left end of the mounting base plate 1. The solid storage tank 16 is located directly below the solid discharge cylinder 5.

[0026] Workers pour waste liquid into a circular screening cylinder 3 through a conical feed pipe 4. The conical feed pipe 4 is designed to guide the waste liquid smoothly into the circular screening cylinder 3 and prevent spillage. The drive motor 10 is started, and the output end of the drive motor 10 rotates, driving the rotating shaft 6 to rotate inside the circular screening cylinder 3. The rotation of the rotating shaft 6 will drive the connecting shaft 7 and the spiral scraper 8 to rotate together. The surface of the spiral scraper 8 contacts the inner wall of the circular screening cylinder 3. During rotation, the spiral scraper 8 continuously scrapes the inner wall of the circular screening cylinder 3. The waste liquid flows inside the circular screening cylinder 3. The solid polyphenylene sulfide particles in it are blocked by the cylinder wall of the circular screening cylinder 3 and cannot pass through. During the rotation, the spiral scraper 8 continuously scrapes off the solid particles attached to the cylinder wall and pushes them towards the solid discharge cylinder 5 along the spiral direction of the spiral scraper 8. The liquid passes through the screen holes of the circular screening cylinder 3 and falls downward into the trapezoidal receiving hopper 11. The liquid falling into the trapezoidal receiving hopper 11 flows into the waste liquid storage tank 13 for storage through the drain pipe 12. The trapezoidal design of the receiving hopper 11 facilitates the centralized collection of liquid and its smooth flow into the drain pipe 12. The solid particles are then pushed by the spiral scraper 8 to the solid discharge cylinder 5. Under their own gravity, the solid particles fall into the solid storage tank 16 directly below for storage. Through the coordinated rotation of the rotating shaft 6, connecting shaft 7, and spiral scraper 8, the solid particles on the inner wall of the circular screening cylinder 3 are continuously scraped off and pushed towards the solid discharge cylinder 5, eventually falling into the storage tank 16. This prevents the accumulation of solid particles on the inner wall of the circular screening cylinder 3, ensuring that the circular screening cylinder 3 always maintains high screening efficiency. It can continuously filter solid particles in the waste liquid, overcoming the problem of reduced filtration efficiency caused by solid particle accumulation in traditional filters. It eliminates the need for frequent cleaning of the surface of the filter device by staff, reducing labor intensity and improving the efficiency of waste liquid filtration by the circular screening cylinder 3.
