Description

Technical Field

[0001] This utility model belongs to the field of polycarboxylate superplasticizer production technology, specifically a self-cleaning inner wall polycarboxylate superplasticizer reactor device. Background Technology

[0002] The polycarboxylate superplasticizer reactor is a core piece of equipment for synthesizing high-performance concrete admixtures, and its development is closely related to the widespread application of polycarboxylate superplasticizers (PCE). With the increasing demands for workability, strength, and durability in modern construction projects, traditional naphthalene-based or aliphatic superplasticizers are gradually failing to meet the needs of high-performance concrete. Polycarboxylate superplasticizers, due to their strong designability of molecular structure, high water reduction rate, and good environmental performance, have become the mainstream choice.

[0003] Existing technologies also have the following shortcomings: The existing polycarboxylate superplasticizer reactors suffer from the following defects: the stirring mechanism has a single function and cannot simultaneously remove residual materials from the reactor wall, requiring manual cleaning after shutdown; the fixed spray system has cleaning dead zones and cannot fully cover the inner wall of the reactor; each functional unit operates independently, resulting in low automation and low production efficiency; furthermore, polycarboxylate materials are highly viscous and easily form scale on the inner wall, which, over time, affects heat transfer efficiency and may cause fluctuations in product quality. These defects collectively lead to high equipment cleaning and maintenance costs, poor production continuity, and difficulty in ensuring product consistency. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a self-cleaning inner wall polycarboxylate superplasticizer reactor device, which solves the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning inner wall polycarboxylate superplasticizer reactor device, comprising:

[0006] The reactor body has a drive motor fixedly connected to its top. The reactor body has an inlet and an outlet. A linkage shell is fixedly connected to the inner top of the reactor body. A drive shaft is rotatably connected to the bottom of the linkage shell. Two sets of rotating frames are coaxially fixedly connected to the drive shaft. Multiple inclined scraper plates are fixedly connected to the rotating frames. A stirring blade is coaxially fixedly connected to the bottom of the drive shaft.

[0007] The inclined scraper is closely attached to the inner wall of the reactor body. The top of the linkage shell is rotatably connected to the driving bevel gear. Both sides of the inner wall of the linkage shell are rotatably connected to the driven bevel gear. The driving bevel gear and the driven bevel gear mesh with each other. The output end of the drive motor passes through the reactor body and the linkage shell and is coaxially and fixedly connected to the driving bevel gear. The transmission shaft passes through the linkage shell and is coaxially and fixedly connected to the driving bevel gear. Both sides of the linkage shell are provided with reciprocating spray cleaning mechanisms.

[0008] As a further embodiment of this utility model: the reciprocating spray cleaning mechanism includes a combined support rotatably connected to the bottom of the reactor body, and a spray head is provided at the bottom of the combined support.

[0009] As a further embodiment of this utility model: both sides of the linkage housing are rotatably connected to a swing shaft, the swing shaft passing through the linkage housing and being fixedly connected coaxially with the driven bevel gear.

[0010] As a further embodiment of this utility model: the swing shaft is rotatably connected to a connecting shaft plate on the side away from the linkage housing.

[0011] As a further embodiment of this utility model: the connecting shaft plate is rotatably connected to the combined bracket on the corresponding side.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention uses a drive motor to rotate a transmission shaft, and the stirring blades on the drive shaft can efficiently stir and mix the water-reducing agent. Simultaneously, an inclined scraper rotates with the shaft, effectively removing residual material adhering to the inner wall of the reactor and preventing scaling. Furthermore, a bevel gear set inside the linkage housing synchronously drives the reciprocating spray mechanism, causing the spray head to reciprocate axially during stirring, thereby significantly expanding the cleaning coverage area, improving the cleaning effect on the inner wall of the reactor, and ensuring equipment cleanliness and production efficiency.
