Technical Field
[0001] The utility model relates to the technical field of reaction kettles, in particular to a polyacrylamide polymerization reaction kettle. Background Technique
[0002] Polyacrylamide is a linear organic polymer and also a polymer water treatment flocculant product. In the production process of polyacrylamide, a corresponding reaction kettle is required for its polymerization reaction. Polymerization is the core step in the production of polyacrylamide. The prepared raw materials are added into the polymerization kettle, and by controlling the temperature and pressure, the raw materials undergo a polymerization reaction under the action of an initiator to generate polyacrylamide colloid. The polymerization reaction requires a certain amount of time and continuous stirring to ensure uniform reaction.
[0003] The traditional reaction kettle is heated by injecting high-temperature steam into the jacket arranged on the outside. However, in this way, the heat is transferred from the outside to the inside, and it is easy to have the situation of uneven heating, which is not conducive to the polymerization reaction. Therefore, we propose a polyacrylamide polymerization reaction kettle. Content of the Utility Model

A plurality of through holes penetrating up and down are evenly arranged on the surface of the heat conduction frame.
[0006] By adopting the above technical scheme, after the raw materials enter the interior of the kettle body, high-temperature steam is introduced into the interior of the jacket to achieve the purpose of heating the kettle body on the outside of the kettle body. At the same time, the heat conduction frame is driven to reciprocate up and down, and high-temperature steam is also introduced into it, which can stir the raw materials and uniformly heat the raw materials on the inside.
[0007] Optionally, the heat conduction frame is in an arc shape bent downward, and both sides of the heat conduction frame are horizontally arranged.

[0025] Please refer to Figures 1-3 , the present utility model provides a technical solution: a polyacrylamide polymerization reactor, including a kettle body 1 and a jacket 2. The jacket 2 is fixed on the outer ring below the kettle body 1, and steam pipes 21 communicating with its interior are connected to both upper sides of the jacket 2. During use, the two steam pipes 21 are respectively connected to the high-temperature steam supply pipeline and the exhaust pipeline of the boiler, and high-temperature steam can be introduced into the interior of the jacket 2, thereby heating the raw materials inside the kettle body 1 from the outside of the kettle body 1, and finally the high-temperature steam is discharged from the other side. In addition, a condensing pipe 22 is connected to the bottom side of the jacket 2, and the condensing pipe 22 communicates with the interior of the jacket 2. The condensing pipe 22 can be connected to the drainage pipeline and a valve is provided, and the valve can be regularly opened to discharge the condensed water generated by the high-temperature steam from the condensing pipe 22 to the outside. A ring plate 11 is fixedly surrounded on the outer ring of the kettle body 1, and the ring plate 11 is located above the jacket 2. During use, feet or other support structures can be provided to support below the outer ring of the ring plate 11 to realize the support of the structure of the kettle body 1.
[0026] Feed inlets 12 are vertically connected to both upper sides of the kettle body 1, and the feed inlets 12 communicate with the interior of the kettle body 1. The feed inlets 12 can be connected to the supply pipelines of different raw materials. During use, raw materials enter the interior of the kettle body 1 through the feed inlets 12. In addition, a discharge outlet 13 is connected to the middle position at the bottom of the kettle body 1, and the discharge outlet 13 penetrates to the outside of the jacket 2 and communicates with the interior of the kettle body 1. The discharge outlet 13 is connected to a discharge pipe and a valve is installed thereon. The valve can be opened after the polymerization reaction is completed to discharge the reacted materials to the outside.
[0027] On both sides above the kettle body 1, electric push rods 3 are vertically installed. The extending ends of the electric push rods 3 penetrate downward into the interior of the kettle body 1. At the ends of the two electric push rods 3 on both sides, a heat conduction frame 4 is fixed. On the surface of the heat conduction frame 4, a plurality of through holes 41 penetrating up and down are evenly opened. During the polymerization reaction, the electric push rod 3 can drive the heat conduction frame 4 to reciprocate up and down, and the raw materials can be evenly stirred through the through holes 41. In addition, the heat conduction frame 4 is a hollow structure, and on both sides of the jacket 2, a conduit 23 penetrating into the interior of the kettle body 1 is connected. A high-temperature hose 231 is connected and communicated between the two conduits 23 on both sides and the heat conduction frame 4. When the heat conduction frame 4 is driven to move up and down, the high-temperature hose 231 can deform to keep the interior of the heat conduction frame 4 in a communicating state with the interior of the jacket 2 through the conduit 23, so that high-temperature steam can be introduced into the hollow heat conduction frame 4, and the heat conduction frame 4 can be heated to uniformly heat the raw materials from the inside.
[0028] The heat conduction frame 4 is in an arc shape bent downward, and both sides of the heat conduction frame 4 are horizontally arranged. Therefore, when the heat conduction frame 4 is driven to lower its height, the downwardly bent heat conduction frame 4 can closely adhere to the inner bottom of the kettle body 1, ensuring sufficient stirring and heating of the raw materials.
[0029] During use, connect the feed inlet 12 to different feed pipes, connect the two steam pipes 21 to a high-temperature boiler and a reflux pipe respectively, connect the bottom condensate pipe 22 to a condensate water recovery pipe, and connect the bottom discharge port 13 to a discharge pipe with a valve. During the polymerization reaction, each raw material is injected into the interior of the kettle body 1 through different feed inlets 12. After the high-temperature steam enters the interior of the jacket 2, it heats the raw materials inside the kettle body 1 on the outside of the kettle body 1. At the same time, high-temperature steam enters the heat conduction frame 4 through the conduit 23 and the high-temperature hose 231. The heat conduction frame 4 is driven to reciprocate up and down by the electric push rod 3, so that the raw materials can be stirred through the through holes 41. At the same time, the high-temperature steam entering the heat conduction frame 4 can use the heat conduction frame 4 to heat the raw materials, achieving the purpose of stirring and uniformly heating the raw materials. The condensate water generated by the steam can be discharged through the condensate pipe 22. After the reaction is completed, open the valve on the discharge pipe connected to the discharge port 13 to discharge the materials.
