Technical Field
[0001] The utility model relates to the technical field of reactors, in particular to a polyacrylamide reactor capable of preventing sticking. Background Art
[0002] Polyacrylamide is a linear organic high molecular polymer and also a high molecular water treatment flocculant product. During the production process, polyacrylamide needs to be polymerized in a corresponding reactor. Polymerization is the core step in polyacrylamide production. The prepared raw materials are added to the polymerization reactor. By controlling the temperature and pressure, the raw materials undergo polymerization under the action of the initiator to generate polyacrylamide colloid. The polymerization reaction takes a certain amount of time and requires constant stirring to ensure a uniform reaction.
[0003] During the reaction process, solid matter is prone to sticking to the inner wall surface of the reactor where the reaction solution and the air inside the reactor meet. These solids can dry and adhere to the inner wall surface at high temperatures, making it difficult to clean later. Therefore, we propose a polyacrylamide reactor that prevents sticking.

When the reaction is in progress, a corrosion-resistant pump can be used to draw the solution into the ring cover, and the solution leaks out from the leakage holes and flows downward along the inner wall of the reactor body to avoid solid materials sticking to the inner wall. After the reaction is completed, heated water can be used to flush the inner wall to achieve a better anti-sticking effect, thereby solving the problems raised in the background technology.

After the reaction is completed, hot water can be used to flush it again, which has a better anti-sticking effect.
[0007] Optionally, an electric heating plate is fixed inside the ring tube, and the electric heating plate is closely attached to the inner wall surface of the ring tube.

[0024] See also Figure 1-3 The present invention provides a technical solution: a polyacrylamide reactor for preventing sticking, comprising a reactor body 1 and a stirring rod 2, the stirring rod 2 being rotatably installed in the middle position of the interior of the reactor, a motor 21 being installed on the upper surface of the reactor body 1 at the top of the stirring rod 2, the motor 21 being transmission-connected to the stirring rod 2, a feed pipe 11 being vertically connected to the upper part of both sides of the reactor body 1, the feed pipe 11 being connected to the interior of the reactor body 1, a jacket being further provided on the lower outer side of the reactor body 1, when processing polyacrylamide, the raw material is passed into the interior of the reactor body 1 through the feed pipe 11, high-temperature steam is passed into the interior of the jacket through the side pipe, and then the jacket can be used to heat the raw material inside the reactor body 1, and the motor 21 can be started to drive the stirring rod 2 to rotate to react the raw materials, a discharge pipe communicating with the interior of the reactor body 1 is connected to the bottom of the reactor body 1, which is sealed by a sealing valve installed during the reaction, and the sealing valve can be opened to discharge the material after the reaction is completed.
[0025] In order to make the solid material stick to the inner wall surface of the kettle body 1 at the interface between the solution and the air inside the kettle body 1 during the reaction, a ring cover 4 is fixed around the upper part of the interior of the kettle body 1. The upper height of the ring cover 4 is greater than the bottom height of the feed pipe 11. The bottom surface of the ring cover 4 is evenly provided with a plurality of leakage holes 41 close to the inner wall surface of the kettle body 1. At the same time, a corrosion-resistant pump 5 is also provided. Its inlet is connected to the lower part of the interior of the kettle body 1 through an extraction pipe 51, and the outlet of the corrosion-resistant pump 5 is connected to the ring cover through a reflux pipe 52. 4, during the reaction, the heated solution is drawn into the annular cover 4, then leaks out from the leak hole 41, flows downward along the inner wall of the kettle 1, and has a flushing effect on the inner wall, which can achieve the purpose of preventing the material from sticking. A filter screen 511 is fixed inside the extraction pipe 51. The filter screen 511 is placed at the end of the extraction pipe 51 and is flush with the inner wall of the kettle 1, which can prevent solids in the solution from being drawn in, thereby preventing the extraction pipe 51, the corrosion-resistant pump 5 or the reflux pipe 52 from being blocked.
[0026] A ring tube 3 is also fixed around the inside of the kettle body 1 above the ring cover 4. The bottom of the ring tube 3 is evenly connected with multiple water outlet pipes 31 connected to the inside. The water outlet pipe 31 is placed above the ring cover 4, and the side of the ring tube 3 is connected with a water inlet pipe 32 that runs through the outside of the kettle body 1. A valve 321 is installed on the water inlet pipe 32 to control the opening and closing of the water inlet pipe 32 so that the water inlet pipe 32 is connected to the clean water supply pipe. When the reaction is completed, the valve 321 can be opened to allow clean water to enter the ring tube 3, be discharged from the water outlet pipe 31 and fall into the ring cover 4, and then also leak out from the leak hole 41, flow downward along the inner wall of the kettle body 1, have a flushing effect on the inner wall, and can wash away residual sticky materials.
[0027] In order to improve the flushing effect of clean water, an electric heating plate 33 is fixed inside the ring tube 3. The electric heating plate 33 is close to the inner wall surface of the ring tube 3, and the clean water can be heated. When flushing the inner wall of the kettle body 1, the warm water can reduce the viscosity of the material, making it easier to be flushed down.
[0028] When in use, the feed pipe 11 is connected to the feed pipe with a sealing valve, and the bottom discharge pipe is connected to the discharge pipe with a sealing valve, and the jacket is connected to the steam supply pipe and the discharge pipe. The raw material solution can be passed from the feed pipe 11 into the interior of the kettle body 1, heated by the high-temperature steam in the jacket, and stirred by the motor 21 driving the stirring rod 2 to rotate. In order to prevent the inner wall surface of the kettle body 1 at the junction of the solution and the air inside the kettle body 1 from adhering to solid materials and being dried and stuck during the reaction process, the corrosion-resistant pump 5 can be started during the reaction to extract the solution inside the kettle body 1, and then pass it into the interior of the ring cover 4 through the reflux pipe 52, and leak out from the leakage holes 41 evenly distributed at the bottom of the ring cover 4, and flow downward along the inner wall of the kettle body 1. Solids adhering to the inner wall surface of the kettle body 1 at the interface between the solution and the air inside the kettle body 1 can be washed down to avoid the accumulation of solid materials at the interface. After the reaction inside the kettle body 1 is completed and the materials are discharged through the discharge pipe, the valve 321 can be opened again to allow clean water to be injected into the ring pipe 3 through the water inlet pipe 32. At the same time, the electric heating plate 33 is started to heat the clean water. After that, the clean water flows into the ring cover 4 from the water outlet pipe 31, and similarly leaks out from the leakage holes 41 evenly distributed at the bottom of the ring cover 4 to wash the inner wall of the kettle body 1. Since the clean water is heated to a warm state, it is conducive to washing down the sticky materials and finally discharged from the bottom discharge port, thereby achieving the purpose of preventing the inner wall of the reactor from sticking. After the flushing is completed, the electric heating plate 33 is stopped and the valve 321 is closed.
