Description

Technical Field

[0001] This utility model relates to the field of polymerization reaction technology, specifically to a bulk polymerization reactor. Background Technology

[0002] Bulk polymerization, as a key process in the preparation of polymer materials, places extremely high demands on the mixing efficiency, material handling capacity, and equipment stability of the reaction equipment. With the development of the new materials industry, novel polymerization reaction systems are constantly emerging, requiring even higher standards for the flexibility and reliability of the stirring and scraping functions within the reactor.

[0003] Currently, existing bulk polymerization reactors have two major problems: First, the angle of the agitator is fixed and cannot be dynamically adjusted according to the material viscosity and reaction process, resulting in uneven mixing of high-viscosity materials, low reaction efficiency, and an average batch reaction time extension of 20%; Second, the scraping device on the inner wall of the tank is mostly rigidly connected. When the material adhesion is too great, the scraper is prone to deformation or even breakage due to stress, and may also scratch the tank, resulting in high maintenance costs. According to statistics, the downtime for maintenance caused by scraping device failure exceeds 50 hours per year, which seriously affects the continuity of production. In view of this, we propose a bulk polymerization reactor. Utility Model Content

[0004] The main objective of this invention is to provide a bulk polymerization reactor that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a bulk polymerization reactor, comprising a reaction vessel, a lid on the top of the reaction vessel, a rotating shaft rotatably connected to the inner wall of the lid, an adjusting assembly on the lid, and a stirring paddle on the adjusting assembly. The adjusting assembly includes:

[0006] A threaded seat is fixedly connected to the bottom of the can lid, and a threaded rod is threadedly connected to the inner wall of the threaded seat;

[0007] A rotating block is fixedly connected to the top of the threaded rod, and an arc-shaped retaining seat is rotatably connected to the top of the threaded rod.

[0008] A synchronization plate is fixedly connected to the bottom of the rotating shaft, and a synchronization disk is slidably connected to the outer wall of the synchronization plate;

[0009] A sliding plate is fixedly connected to the bottom of the synchronization disk, and a push sleeve is fixedly connected to the outer wall of the sliding plate;

[0010] A connecting block is fixedly connected to the outer wall of the stirring paddle, and a connecting rod is fixedly connected to the outer wall of the connecting block.

[0011] Preferably, the outer wall of the stirring paddle is rotatably connected to the outer wall of the synchronization plate, and multiple sets of stirring paddles are provided.

[0012] Preferably, the outer wall of the synchronization plate is fixedly connected to a guide sleeve, and the outer wall of the sliding plate is slidably connected to the inner wall of the guide sleeve.

[0013] Preferably, the push sleeve has a push groove, and the outer wall of the connecting rod is slidably connected to the inner wall of the push groove.

[0014] Preferably, the outer wall of the synchronization plate is fixedly connected to a base frame, and the outer wall of the base frame is slidably connected to a sliding outer sleeve.

[0015] Preferably, a buffer block is fixedly connected to the outer wall of the sliding jacket, and a scraper is fixedly connected to the top of the buffer block.

[0016] Preferably, the outer wall of the buffer block is fixedly connected to a connector, and the base frame is elastically connected to the connector by a spring.

[0017] This invention provides a bulk polymerization reactor. It has the following beneficial effects:

[0018] (1) The bulk polymerization reactor uses a rotating block and a threaded rod that moves up and down precisely on the threaded seat, driving the arc-shaped card seat, synchronous disk and sliding plate to move in coordination. The angle of the stirring paddle can be adjusted quickly. This design can flexibly change the angle of the stirring paddle according to different material characteristics and reaction stages. Compared with the traditional fixed-angle stirring paddle, the material mixing efficiency is improved, and the problem of insufficient or excessive reaction in some areas is effectively avoided.

[0019] (2) When the motor-driven rotating shaft of the main polymerization reactor rotates, the base frame drives the scraper to rotate synchronously and scrape off the material on the inner wall of the tank. When the material adhesion force exceeds the spring preload, the buffer block compresses the spring and slides, causing the scraper to automatically retract, thus avoiding scraper deformation or tank wear caused by hard scraping. Tests have shown that this structure extends the scraper's service life by several times, while reducing material residue, significantly improving cleaning efficiency and equipment reliability.

[0029] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-7This utility model proposes a bulk polymerization reactor, including a reaction tank 1. A tank cover 2 is provided on the top of the reaction tank 1. A rotating shaft 3 is rotatably connected to the inner wall of the tank cover 2. A lifting frame is provided on the top of the tank cover 2, and a motor is fixedly installed on the top of the lifting frame. The output end of the motor is connected to the rotating shaft 3. This is prior art and will not be described in detail. An adjustment component 4 is provided on the tank cover 2, and a stirring paddle 5 is provided on the adjustment component 4. The adjustment component 4 includes a threaded seat 41. The bottom of the tank cover 2 is fixedly connected to the threaded seat 41, and a threaded rod 42 is threadedly connected to the inner wall of the threaded seat 41. A rotating block 43 is fixedly connected to the top of the threaded rod 42, and an arc-shaped retainer 44 is rotatably connected to the top of the threaded rod 42. Rotating the rotating block 43 drives the threaded rod 42 to move spirally on the threaded seat 41. An arc-shaped groove is provided on the arc-shaped retainer 44. A synchronization disc 4... The outer wall of the 6 is slidably connected to the inner wall of the arc-shaped groove, and the curvature of the arc-shaped groove is precisely matched with the curvature of the outer wall of the synchronous disk 46. The outer wall of the synchronous disk 46 is slidably connected to the inner wall of the arc-shaped groove. Since the synchronous disk 46 cannot move left or right, it cooperates with the arc-shaped groove to prevent the arc-shaped card seat 44 from rotating, thereby guiding the movement of the arc-shaped card seat 44. Therefore, when the height of the threaded rod 42 changes, it drives the height of the arc-shaped card seat 44 to change synchronously, ensuring that the arc-shaped card seat 44 will not rotate. At the same time, when the height of the arc-shaped card seat 44 changes, it drives the synchronous disk 46 to slide on the synchronous plate 45, thereby driving the sliding long plate 47 to move synchronously. The bottom of the rotating shaft 3 is fixedly connected to the synchronous plate 45, and the outer wall of the synchronous plate 45 is slidably connected to the synchronous disk 46.

[0032] In this utility model, a sliding plate 47 is fixedly connected to the bottom of the synchronous disc 46, and a push sleeve 48 is fixedly connected to the outer wall of the sliding plate 47. The movement of the sliding plate 47 drives the push sleeve 48 to move. A connecting block 49 is fixedly connected to the outer wall of the stirring paddle 5, and a connecting rod 410 is fixedly connected to the outer wall of the connecting block 49. The outer wall of the stirring paddle 5 is rotatably connected to the outer wall of the synchronous plate 45. Multiple sets of stirring paddles 5 are provided, with two sets of stirring paddles 5 at the same height, distributed on both sides of the synchronous plate 45. A guide sleeve 6 is fixedly connected to the outer wall of the synchronous plate 45, and the outer wall of the sliding plate 47 is slidably connected to the inner wall of the guide sleeve 6. Multiple sets of guide sleeves 6 are provided, and the movement of the synchronous plate 45 is guided by the guide sleeves 6.

[0033] Furthermore, a pushing groove is provided on the pushing sleeve 48, and the outer wall of the connecting rod 410 is slidably connected to the inner wall of the pushing groove. The moving of the pushing groove causes the connecting rod 410 to move. Through the cooperation of the stirring paddle 5 and the connecting block 49, the connecting rod 410 moves in an arc. When the connecting rod 410 moves, the angle of the stirring paddle 5 on the synchronous plate 45 is changed through the connecting block 49, thus completing the angle adjustment of the stirring paddle 5.

[0034] Furthermore, a base frame 7 is fixedly connected to the outer wall of the synchronization plate 45, and a sliding sleeve 8 is slidably connected to the outer wall of the base frame 7. One end of the base frame 7 is C-shaped, and the C-shaped end is fixedly connected to the synchronization plate 45 by screws. The other end of the base frame 7 is round, and the outer wall of the round end is slidably connected to the sliding sleeve 8. A buffer block 9 is fixedly connected to the outer wall of the sliding sleeve 8, and a scraper 10 is fixedly connected to the top of the buffer block 9. The scraper 10 contacts the inner wall of the reaction vessel 1, which facilitates scraping the inner wall of the vessel and reduces the situation where the material sticks to the inner wall of the vessel. A connector 11 is fixedly connected to the outer wall of the buffer block 9, and the base frame 7 and the connector 11 are elastically connected by a spring. When the material sticks strongly to the vessel, the elastic connection between the connector 11 and the spring allows the buffer block 9 to slide, driving the scraper 10 away from the inner wall of the vessel, thereby avoiding damage to the scraper 10.

[0035] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install, and debug the circuit according to the needs of use to ensure that all electrical appliances can work normally. All components are general standard parts or parts known to those skilled in the art. Their structure and principles can be learned by these technicians through technical manuals or conventional experimental methods, and no specific restrictions are made here. In use, rotating the rotating block 43 drives the threaded rod 42 to move helically on the threaded seat 41. When the height of the threaded rod 42 changes, the height of the arc-shaped retainer 44 changes synchronously. When the height of the arc-shaped retainer 44 changes, the synchronous disc 46 slides on the synchronous plate 45. The synchronous disc 46 sliding on the synchronous plate 45 drives the sliding long plate 47 to move synchronously, causing the push sleeve 48 to move, thereby facilitating the change of the position of the connecting rod 410, changing the angle of the stirring paddle 5 on the synchronous plate 45, and completing the angle adjustment of the stirring paddle 5.

[0036] When the motor starts and drives the rotating shaft 3 to rotate, the rotating shaft 3 drives the synchronous plate 45 to rotate, causing the stirring paddle 5 on it to stir. At the same time, it drives the base frame 7 to rotate synchronously. Together with the buffer block 9 and the scraper 10, the material is scraped off the inner wall of the tank, reducing the material from sticking to the inner wall of the tank. When the material sticks strongly to the tank, the elastic connection between the connector 11 and the spring allows the buffer block 9 to slide, moving the scraper 10 away from the inner wall of the tank, thus avoiding damage to the scraper 10.

[0037] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
