[0002] Polyacrylamide is a water-soluble polymer coagulant that can be used as a coagulant aid, sludge dehydrating agent, and coagulation and sedimentation agent. It is widely used in the treatment of chemical industrial wastewater and waste liquid, municipal sewage treatment, purification and sedimentation of high turbidity water, coal washing, metallurgy, steel industry, zinc, aluminum processing industry, electronics industry and other water treatment. Solid polyacrylamide needs to be dissolved into a glue-like liquid before use.
[0003] When dissolving solid polyacrylamide, a stirring device is usually used. The stirring device mainly includes a stirring box and a stirring shaft. An anchor-type or frame-type stirring paddle is arranged on the stirring shaft to reduce the possibility of the molecular chain of polyacrylamide breaking. The upper end surface of the stirring box is open, and a screen box is slidably connected to the opening of the stirring box. The screen box reciprocates along the length direction of the stirring box to evenly transport the powdered polyacrylamide into the stirring box.

DETAILED DESCRIPTION
[0031] The following is combined with Figure 1-3 This application is described in further detail.
[0032] The present application embodiment discloses a stirring device with a reciprocating screening mechanism. Figure 1 A stirring device with a reciprocating screening mechanism comprises a stirring barrel 1 and a screen 2, wherein the screen 2 is slidably connected in the stirring barrel 1 in the horizontal direction. The stirring barrel 1 is connected with a water inlet pipe 11 and a plurality of feeding pipes 12 for feeding powdered polyacrylamide, and each feeding pipe 12 is arranged opposite to the screen 2. A stirring shaft 3 is rotatably connected in the stirring barrel 1, and the stirring shaft 3 comprises a main shaft 31 and an eccentric shaft 32. The main shaft 31 is rotatably connected in the stirring barrel 1, and the eccentric shaft 32 is eccentrically arranged compared to the main shaft 31. The eccentric shaft 32 is connected to the screen 2 through a connecting component 4, and the eccentric shaft 32 is connected to the main shaft 31 through a connecting shaft 33. A stirring paddle 34 is coaxially fixed to the end of the main shaft 31 away from the screen 2.
[0033] The worker puts the powdered polyacrylamide into the mixing barrel 1 from the feeding pipe 12, and transports water into the mixing barrel 1 from the water inlet pipe 11. The main shaft 31 rotates again and drives the eccentric shaft 32 and the stirring paddle 34 to rotate. The stirring paddle 34 mixes the polyacrylamide and water in the mixing barrel 1 to stir the polyacrylamide into a glue state. At the same time, the eccentric shaft 32 controls the connecting component 4 to drive the screen 2 to move back and forth. The screen 2 screens the powdered polyacrylamide. On the one hand, the polyacrylamide is distributed more evenly in the mixing barrel 1. On the other hand, it reduces the possibility of blocky polyacrylamide entering the mixing barrel 1 and causing polyacrylamide to agglomerate, thereby improving the effect of the stirring device stirring the polyacrylamide. The screen 2 located in the mixing barrel 1 reduces the phenomenon of powdered polyacrylamide floating around, making it less likely for the polyacrylamide to be reduced, thereby improving the purity of the glue-like polyacrylamide after stirring by the stirring device.
[0034] Reference Figure 1 and Figure 2A motor 13 is fixed on the mixing barrel 1, and the output end of the motor 13 is coaxially fixed with the main shaft 31. The connecting assembly 4 includes a push rod 41, a moving plate 42 and a guide frame 43. One end of the push rod 41 is rotatably connected to the eccentric shaft 32, and the other end is rotatably connected to the moving plate 42. The guide frame 43 is fixed in the mixing barrel 1 in the horizontal direction, and the moving plate 42 is slidably connected to the guide frame 43, and the side of the moving plate 42 away from the guide frame 43 is fixed to the screen 2 through a connecting rod 44.
[0035] When the polyacrylamide is stirred, the motor 13 starts and drives the main shaft 31 to rotate, and the main shaft 31 controls the connecting shaft 33 to drive the eccentric shaft 32 to rotate. The eccentric shaft 32 then drives the push rod 41 to move, and the push rod 41 then drives the moving plate 42 to move along the guide frame 43, and the moving plate 42 then drives the connecting rod 44 and the screen 2 to move. Since the eccentric shaft 32 is eccentrically arranged compared to the main shaft 31, the push rod 41 can drive the moving plate 42 to move back and forth along the guide frame 43, that is, drive the screen 2 to move back and forth, so that the screen 2 can transport the polyacrylamide to different positions of the stirring barrel 1 more evenly, thereby improving the stirring effect of the stirring device on the polyacrylamide.
[0036] Reference Figure 2 The eccentric shaft 32 is sleeved with a ball bearing 45, and the movement of the push rod 41 away from the moving plate 42 is connected to the ball bearing 45. The ball bearing 45 facilitates the connection between the push rod 41 and the eccentric shaft 32, and reduces the friction between the push rod 41 and the eccentric shaft 32, so that the eccentric shaft 32 can drive the push rod 41 to move more stably.
[0037] Reference Figure 1 and Figure 3 The screen 2 is provided with a clearance hole 21 for the main shaft 31 to pass through, so that the main shaft 31 is not easy to interfere with the screen 2 during use, so that the main shaft 31 and the screen 2 can work more stably.
[0038] Reference Figure 3 In order to improve the stability of the screen 2 when it moves, a bracket 14 is fixed in the mixing barrel 1, and the screen 2 is slidably connected to the bracket 14. At this time, the bracket 14 can provide guidance and support for the screen 2, so that the screen 2 can move back and forth in the mixing barrel 1 more stably.
[0039] Reference Figure 1A heating jacket 5 is fixed on the outside of the mixing barrel 1, and a plurality of electric heating wires 51 are arranged in the heating jacket 5. A digital display control board 15 for controlling the electric heating wires 51 is arranged on the mixing barrel 1. During the mixing of polyacrylamide, the electric heating wires 51 are started and heat the polyacrylamide and water in the mixing barrel 1, thereby accelerating the mixing speed of the polyacrylamide. At the same time, the digital display control board 15 facilitates workers to observe the specific temperature of the electric heating wires 51 and control the electric heating wires 51, so that the temperature in the mixing barrel 1 is within the set range.
[0040] Reference Figure 1 The end of the mixing barrel 1 away from the feeding pipe 12 is connected to a feeding pipe 16, and a manual valve 161 is provided on the feeding pipe 16. After the polyacrylamide is stirred, the worker opens the manual valve 161, and the glue-like polyacrylamide on the stirring shaft 3 can be discharged from the feeding pipe 16, so that the worker can collect the stirred polyacrylamide.
[0041] The implementation principle of the stirring device with a reciprocating screening mechanism in the embodiment of the present application is as follows: when it is necessary to stir polyacrylamide, the worker puts the polyacrylamide into the stirring barrel 1 from the feeding pipe 12, at which time the motor 13 starts and drives the stirring shaft 3 to rotate, and the stirring paddle 34 can mix the polyacrylamide and water to stir the polyacrylamide into a glue state. At the same time, under the transmission action of the connecting component 4, the screen 2 moves back and forth, on the one hand, the polyacrylamide is transported to the stirring barrel 1 more evenly, and on the other hand, the powdered polyacrylamide is screened, so that the block polyacrylamide is not easy to enter the stirring barrel 1, and the polyacrylamide is not easy to clump, thereby improving the effect of the stirring device stirring the polyacrylamide. At the same time, the screen 2 located in the stirring barrel 1 makes it difficult for the powdered polyacrylamide to float around, reducing the possibility of loss of polyacrylamide, thereby improving the purity of the glue-like polyacrylamide after stirring by the stirring device.
[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
