Description

Technical Field

[0001] This utility model relates to the field of polyacrylamide technology, specifically to a purification device for polyacrylamide. Background Technology

[0002] Polyacrylamide is currently a linear polymer with a wide range of applications and many valuable properties. It is a hard, glassy solid at room temperature. Product forms include liquid, latex, white powder, translucent beads, and flakes. It has good thermal stability and can dissolve in water in any proportion to form a uniform and transparent liquid. After long-term storage, the viscosity of the solution may decrease due to the slow degradation of the polymer, especially under poor storage and transportation conditions.

[0003] Currently, the stability of polyacrylamide is difficult to control during production due to various factors such as formulation, raw materials, and production process. The impurity content may be high. These impurities may originate from quality problems of raw materials and additives, or they may be generated during the production process. Therefore, purifying impurities in polyacrylamide is a challenging task that requires strict production control and purification processes. Utility Model Content

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a purification device for polyacrylamide, comprising:

[0022] Purify the outer frame 1;

[0023] The purification structure is located within the purification outer frame 1;

[0024] The purification structure includes a partition plate 2, a crystallization frame 3, a filter frame 4, multiple conveying pipes 5, a conveying frame 6, and a sliding frame 7. The outer walls of the partition plate 2 and the crystallization frame 3 are fixedly embedded in the purification outer frame 1. The ends of the filter frame 4 and the conveying frame 6 that are far apart from each other are fixedly embedded in the purification outer frame 1, while the ends of the filter frame 4 and the conveying frame 6 that are close to each other are fixed together. The inner wall of the partition plate 2 is fixedly sleeved on the filter frame 4, and the inner wall of the crystallization frame 3 is fixedly sleeved on the filter frame 4 and the conveying frame 6. One end of each of the multiple conveying pipes 5 is connected to the crystallization frame 3 at equal intervals along the circumferential surface, and the other end of each of the multiple conveying pipes 5 is connected to the conveying frame 6. The outer wall of the sliding frame 7 is slidably embedded in the conveying frame 6 and the purification outer frame 1.

[0025] In this implementation scheme: the purification outer frame 1 can protect the internal structure, and the partition plate 2 can separate the interior of the purification outer frame 1, so that the polyacrylamide aqueous solution can be concentrated into the filter frame 4, filtered by the filter frame 4 and then enter the crystallization frame 3. The temperature and other conditions in the crystallization frame 3 are controlled to crystallize the polyacrylamide aqueous solution, which then enters the conveying frame 6 through multiple conveying pipes 5. The sliding frame 7 moves downward and enters the sliding frame 7.

[0026] Specifically, the upper surface of the outer wall of the filter frame 4 is provided with multiple feed holes at equal intervals along the circumference, and the lower surface of the outer wall of the filter frame 4 is provided with filter mesh holes.

[0027] In this embodiment, the polyacrylamide aqueous solution can enter the filter frame 4 through multiple feed holes and be filtered by the filter mesh.

[0028] Specifically, the top of the outer wall of the purification frame 1 is connected to multiple feed pipes 8, and a control motor 9 is installed at the top center of the purification frame 1. The output end of the control motor 9 is fixed with a rotating rod 10, and the outer wall of the rotating rod 10 is rotatably embedded in the filter frame 4 and the conveying frame 6.

[0029] In this embodiment: polyacrylamide aqueous solution can be introduced into the spacer plate 2 and the purification frame 1 through multiple feed pipes 8, and the output end of the control motor 9 drives the rotating rod 10 to rotate when it is powered on.

[0030] Specifically, a main threaded frame 11 is fixedly sleeved on the upper surface of the outer wall of the rotating rod 10, and a secondary threaded frame 12 is fixedly sleeved on the lower surface of the outer wall of the rotating rod 10.

[0031] In this embodiment: the main threaded frame 11 rotates with the rotating rod 10, which can make the polyacrylamide aqueous solution in the filter frame 4 fully stirred, thereby improving the filtration process. The auxiliary threaded frame 12 rotates with the rotating rod 10, which can break up the crystals entering the sliding frame 7 and prevent them from forming lumps.

[0032] Specifically, multiple hydraulic rods 13 are installed at equal intervals along the circumferential surface of the bottom outer wall of the sliding frame 7, and the output ends of the multiple hydraulic rods 13 are fixed on the purification outer frame 1.

[0033] In this embodiment, multiple hydraulic rods 13 are used to push the output end of the hydraulic rod onto the purification outer frame 1, thereby controlling the sliding frame 7 to move up and down.

[0034] Specifically, the upper surface of the outer wall of the sliding frame 7 is provided with multiple connecting holes at equal intervals along the circumference, and the bottom of the inner wall of the sliding frame 7 is fixedly embedded with an output tube 14.

[0035] In this embodiment, the multiple connecting holes on the sliding frame 7 can be slid to align the multiple conveying pipes 5 connecting areas, allowing the crystallization solution to enter the sliding frame 7 and flow out through the output pipe 14.

[0036] In use, the purification outer frame 1 protects the internal structure, and the partition plate 2 separates the interior of the purification outer frame 1, allowing the polyacrylamide aqueous solution to concentrate and enter the filter frame 4. After being filtered by the filter frame 4, it enters the crystallization frame 3. The temperature and other conditions within the crystallization frame 3 are controlled to crystallize the polyacrylamide aqueous solution, which then enters the conveying frame 6 through multiple conveying pipes 5. The sliding frame 7 moves downward and enters the sliding frame 6. Multiple feed holes allow the polyacrylamide aqueous solution to enter the filter frame 4, where it is filtered by the filter mesh. Multiple feed pipes 8 allow the polyacrylamide aqueous solution to enter between the partition plate 2 and the purification outer frame 1. When the control motor 9 is powered on, its output end drives the rotating rod 10 to rotate. The main threaded frame 11 rotates with the rotating rod 10, which can fully stir the polyacrylamide aqueous solution in the filter frame 4, thereby improving the filtration process. The auxiliary threaded frame 12 rotates with the rotating rod 10, which can break up the crystals entering the sliding frame 7, preventing them from forming lumps. Multiple hydraulic rods 13 use hydraulic pressure to push the output end onto the purification outer frame 1, thereby controlling the up and down movement of the sliding frame 7. Multiple connecting holes on the sliding frame 7 can slide to align with the connecting areas of multiple delivery pipes 5, allowing the crystallization solution to enter the sliding frame 7 and flow out through the output pipe 14. This can filter insoluble matter and residual impurities in the polyacrylamide aqueous solution and stabilize the crystallization of the polyacrylamide aqueous solution, thereby obtaining high-purity polyacrylamide.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
