Technical Field

[0001] The utility model relates to the technical field of polymerization reactors, in particular to a polymerization reactor for producing polycarboxylic acid water reducer. Background Art

[0002] Polycarboxylate water reducer is a high-performance water reducer and a cement dispersant used in cement concrete. It is widely used in projects such as roads, bridges, dams, tunnels, and high-rise buildings.

[0003] The existing equipment for preparing polycarboxylate water reducer usually uses a simple stirring rod to stir the raw materials during processing, which not only has low processing efficiency, but also the raw materials may adhere to the inner wall of the shell of the equipment for preparing polycarboxylate water reducer, which will reduce the mixing efficiency of the raw materials, increase the production cost of preparing polycarboxylate water reducer, and also reduce the processing quality of preparing polycarboxylate water reducer. To this end, we propose a polymerization reactor for producing polycarboxylate water reducer. Utility Model Content

[0004] In view of the fact that the existing equipment for preparing polycarboxylic acid water reducer has a reduced reaction, increased the production cost of preparing polycarboxylic acid water reducer, and also reduced the processing quality of preparing polycarboxylic acid water reducer, the utility model provides a polymerization reactor for producing polycarboxylic acid water reducer, which has the advantages of improving mixing efficiency and improving processing quality, and solves the problems raised in the above background technology.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A polymerization reactor for producing polycarboxylate water-reducing agent comprises a reactor body, a plurality of legs are connected to the bottom of the reactor body along the circumferential direction, a discharge pipe is connected to the bottom surface of the reactor body, and a plurality of feed pipes are connected to the upper end of the side wall of the reactor body;

[0007] A connecting shaft is rotatably connected in the kettle body, the upper end of the connecting shaft is telescoped to the top of the kettle body and fixedly connected to a driving motor, a connecting seat is coaxially fixedly connected to the connecting shaft located in the kettle body, and a cross bar is symmetrically connected to the connecting seat;

[0008] A sleeve is rotatably connected to the cross bar, a plurality of connecting plates are circumferentially connected to the outer wall of the sleeve, a plurality of first stirring rods perpendicular to the position of the sleeve are fixedly connected to the side walls of the connecting plates, and a plurality of second stirring rods perpendicular to the position of the sleeve are fixedly connected to the connecting shaft at the lower end of the sleeve.

[0009] Optionally, the ends of the cross bars are fixedly connected with rectangular scrapers extending downward, and the outer walls of the rectangular scrapers are gap-matched with the inner walls of the kettle body.

[0010] Optionally, a curved scraper is fixedly connected to the bottom of the rectangular scraper, and the curved scraper is gap-matched with the inner wall of the lower end of the kettle body.

[0012] Optionally, a control box is fixedly connected to the outer wall of the kettle body, a controller is arranged in the control box, and the solenoid valve and the drive motor are connected to the controller.

[0013] Compared with the prior art, the utility model drives the connecting shaft to rotate through a driving motor, and the second stirring rod stirs and mixes the raw materials. Under the push of the liquid, the connecting plate and the first stirring rod are driven to rotate along the sleeve, and the rotation directions of the first stirring rod and the second stirring rod are different, which effectively improves the mixing efficiency.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1 to Figure 2 The utility model provides a technical solution: a polymerization reactor for producing polycarboxylate water reducer, comprising a reactor body 14, a plurality of legs 7 are connected to the bottom of the reactor body 14 along the circumferential direction, a discharge pipe 11 is connected to the bottom surface of the reactor body 14, and a plurality of feed pipes 1 are connected to the upper end of the side wall of the reactor body 14, such as Figure 1 As shown, in actual use, in order to facilitate the discharge of the mixed raw materials, a solenoid valve 15 is fixedly connected to the discharge pipe 11 and the feed pipe 1. Through the control of the solenoid valve 15, the automatic discharge of the mixed material can be achieved, thereby improving the practicability of the device.

[0019] like Figure 2 As shown, a connecting shaft 3 is rotatably connected inside the kettle body 14, and the upper end of the connecting shaft 3 is telescoped to the top of the kettle body 14 and fixedly connected to a driving motor 4. A connecting seat 10 is coaxially fixedly connected to the connecting shaft 3 located in the kettle body 14, and a cross bar 9 is symmetrically connected to the connecting seat 10. A sleeve 5 is rotatably connected to the cross bar 9, and a plurality of connecting plates 12 are circumferentially connected to the outer wall of the sleeve 5. A plurality of first stirring rods 2 that are perpendicular to the position of the sleeve 5 are fixedly connected to the side wall of the connecting plate 12. When performing a stirring operation, the driving motor 4 drives the connecting shaft 3 to rotate, and the flow of the internal liquid can push the connecting plate 12, thereby driving the connecting plate 12 to rotate along the sleeve 5. The rotating connecting plate 12 can drive the first stirring rod 2 thereon to rotate synchronously, thereby achieving sufficient mixing of the internal liquid, and further ensuring sufficient mixing of the raw materials.

[0020] like Figure 2 As shown, in order to further improve the stirring and mixing efficiency, a plurality of second stirring rods 6 perpendicular to the connection shaft 3 at the lower end of the sleeve 5 are fixedly connected. When the connection shaft 3 rotates, the second stirring rods 6 can be driven to mix the raw materials at the lower end of the kettle body 14, thereby effectively improving the mixing efficiency.

[0021] like Figure 2 As shown, a downwardly extending rectangular scraper 13 is fixedly connected to the end of the cross bar 9, and the outer wall of the rectangular scraper 13 is gapped with the inner wall of the kettle body 14. The bottom of the rectangular scraper 13 is fixedly connected with an arc scraper 8, and the arc scraper 8 is gapped with the inner wall of the lower end of the kettle body 14. When the connecting shaft 3 is driven by the driving motor 4 to rotate, it can synchronously drive the rectangular scraper 13 and the arc scraper 8 to rotate and scrape the inner wall of the kettle body 14 to avoid precipitation at the bottom of the kettle body 14, thereby effectively ensuring the full mixing of the raw materials.

[0022] In summary, the polymerization reactor for producing polycarboxylate water-reducing agent, when used, Figure 1 As shown, a control box 16 is fixedly connected to the outer wall of the kettle body 14 or the support leg 7, and a controller is arranged in the control box 16. The solenoid valve 15 and the drive motor 4 are connected to the controller, and the raw materials are discharged into the kettle body 14 through the feed pipe 1. The drive motor 4 drives the connecting shaft 3 to rotate, and the second stirring rod 6 stirs and mixes the raw materials at the bottom, and under the push of the liquid, the connecting plate 12 and the first stirring rod 2 can be driven to rotate along the sleeve 5. Since the rotation directions of the first stirring rod 2 and the second stirring rod 6 are different, the mixing efficiency can be further improved. While stirring, Figure 2 As shown, the rectangular scraper 13 and the arc scraper 8 can scrape the inner wall of the kettle body 14 to avoid the accumulation of sediment and effectively achieve sufficient mixing.
