Description

Technical Field

[0001] This utility model relates to the field of chemical engineering, and in particular to a multi-chamber reactor for polycarboxylate superplasticizers. Background Technology

[0002] As a high-performance cement dispersant, polycarboxylate superplasticizer significantly reduces concrete viscosity and greatly improves its fluidity and pumpability through its unique dispersion and adsorption properties, making construction more convenient and efficient. At the same time, it can effectively reduce the water-cement ratio and cement usage, enhancing concrete strength and durability while reducing costs. It is widely used in major projects such as highways, bridges, and high-rise buildings. With the rapid development of the infrastructure industry, the market demand for polycarboxylate superplasticizer has surged, and higher requirements have been placed on product quality stability and production efficiency. As a result, multi-chamber reactors for polycarboxylate superplasticizers have emerged.

[0003] In the multi-chamber reactor for polycarboxylate superplasticizer, each chamber is equipped with an independent stirring device. Through different stirring modes, the materials are quickly and uniformly mixed. At the same time, the temperature, pressure, reaction time and other conditions of each chamber can be independently controlled. Heating and cooling are carried out through jackets or coils. With the help of sensors and control systems, the materials flow orderly between the chambers to complete the mass and heat transfer process, so that the heat is evenly distributed, improving the reaction efficiency and product quality stability.

[0004] At present, multi-chamber reactors for polycarboxylate superplasticizers have indeed played a positive role in promoting the entire industry due to their advantages such as precise temperature control and efficient mixing, significantly improving product quality and stability. However, there are still obvious shortcomings in the raw material transportation process. Each time raw materials are added into the reactor, they must be transported through pipelines of matching specifications. Different raw materials require switching to corresponding pipelines, which makes the operation cumbersome and leads to frequent equipment downtime for maintenance, greatly reducing production efficiency and becoming a key bottleneck restricting capacity improvement and cost control. Therefore, multi-chamber reactors for polycarboxylate superplasticizers are proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-chamber reactor for polycarboxylate superplasticizer, which aims to improve the problems in the prior art where adding raw materials to the reactor requires the use of matching specification pipelines and frequent switching, which is cumbersome, easily leads to equipment downtime for maintenance, and significantly reduces production efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-chamber reactor for polycarboxylate superplasticizer includes a shell. Two cylinders are fixedly connected to the top of the shell. A disc is fixedly connected to the outer wall of each cylinder. A support block is fixedly connected to the top of each disc. A cylinder is fixedly connected inside the support block. A push block is fixedly connected to the other side of the cylinder. Two pull rods are rotatably connected to the top of the push block. A slider is fixedly connected to the side of each pull rod away from the push block. A connecting column is fixedly connected to one side of each slider. A clamping plate is fixedly connected to the other side of the connecting column. Two plugs are slidably connected inside the shell. Two scraping assemblies are fixedly connected to the top of the shell.

[0008] As a further description of the above technical solution:

[0009] The scraping assembly includes two support columns, the bottoms of which are fixedly connected to the top of the housing. A motor is fixedly connected inside the support columns, and a rotating column is fixedly connected to the drive end of the motor. Multiple support plates are fixedly connected to the outer wall of the rotating column. A limit post is fixedly connected to the side of the support plate away from the rotating column, and a scraper is slidably connected to the other side of the multiple limit posts.

[0010] As a further description of the above technical solution:

[0011] The bottoms of both sliders are slidably connected to the top of the disk, and the outer walls of the two connecting posts are slidably connected to the inner wall of the post.

[0012] As a further description of the above technical solution:

[0013] Springs are fitted on the outer walls of the plurality of limiting posts, and a groove is provided on one side of the scraper;

[0014] As a further description of the above technical solution:

[0015] One side of the spring is in contact with one side of the support plate, and the other side of the spring is in contact with the inner wall of the groove of the scraper.

[0016] As a further description of the above technical solution:

[0017] The bottom of the pusher is slidably connected to the top of the disc, and the top of the housing is provided with a liquid inlet;

[0018] As a further description of the above technical solution:

[0019] One side of the disk is in contact with the top of the housing, and an isolation plate is fixedly connected inside the housing;

[0020] As a further description of the above technical solution:

[0021] Multiple stirring blocks are fixedly connected to the outer wall of the rotating column, and the top of the rotating column is rotatably connected to the inner wall of the shell.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, after the cylinder is opened, the unique design and connection structure of the pull rod enable the power generated by the cylinder to be accurately transmitted to the push block. After the push block is subjected to force, it will drive the two sliders to slide along the slide rail on the top of the disc until it reaches the appropriate position. During this process, the movement of the sliders can drive the two clamping plates connected to them to move together, so that the distance between the clamping plates can be flexibly adjusted according to the actual size of the conveying pipe. Whether it is a small-diameter conveying pipe or a pipe with a large diameter, this structure can achieve firm clamping and effectively prevent the conveying pipe from shaking or shifting during use.

[0024] 2. In this utility model, after the motor inside the support column is turned on, the power is transmitted to the rotating column through the transmission structure. Thanks to the stable connection between the support plate and the rotating column, the scraper moves synchronously in a circular motion. During operation, the linkage structure formed by the limiting column and the spring plays a key role. When the rotation speed changes and different centrifugal forces are generated, the spring can extend and deform, pushing the scraper to adjust its position along the direction of the limiting column. When the centrifugal force increases, the spring stretches and the scraper expands outward. When the centrifugal force decreases, the spring resets and the scraper retracts inward, thereby realizing that the scraper adaptively adjusts its circular motion trajectory according to the force conditions.

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.

[0032] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a multi-chamber reactor for polycarboxylate superplasticizer, comprising a shell 1, which plays an important supporting and protective role. Two cylinders 2 are fixedly connected to the top of the shell 1, and a disc 3 is fixedly connected to the outer wall of the cylinders 2, making the entire device more stable. A support block 4 is fixedly connected to the top of the disc 3, which plays an important supporting role. A cylinder 5 is fixedly connected inside the support block 4, and a push block 6 is fixedly connected to the other side of the cylinder 5, so that the force of the cylinder 5 can be transmitted. Two pull rods 7 are rotatably connected to the top of the push block 6, and sliders 8 are fixedly connected to the side of the two pull rods 7 away from the push block 6, so that the force of the cylinder 5 can be transmitted. A connecting column 9 is fixedly connected to one side of the slider 8, and a clamping plate 10 is fixedly connected to the other side of the connecting column 9. The adjacent sides of the two clamping plates 10 can firmly clamp the column of the conveying pipe. Two plugs 20 are slidably connected inside the shell 1, and the outer wall of the plugs 20 slides firmly inside the shell 1. Two scraping assemblies are fixedly connected to the top of the shell 1.

[0033] Reference Figure 3 and Figure 4 The scraping assembly includes two support columns 11, which play an important supporting role. The bottom of the two support columns 11 is fixedly connected to the top of the housing 1, making the entire device more stable. A motor 12 is fixedly connected inside the support column 11. A rotating column 13 is fixedly connected to the drive end of the motor 12, so that the driving force of the motor 12 can be transmitted. Multiple support plates 15 are fixedly connected to the outer wall of the rotating column 13. The support plates 15 play an important connecting role. A limit column 16 is fixedly connected to the side of the support plate 15 away from the rotating column 13. Scrapers 18 are slidably connected to the other side of the multiple limit columns 16 respectively. One scraper 18 is slidably connected to every two limit columns 16. One rotating column 13 drives three scrapers 18 to rotate.

[0034] Reference Figures 2 to 3The bottoms of the two sliders 8 are slidably connected to the top of the disc 3, making the entire device more stable. The outer walls of the two connecting posts 9 are slidably connected to the inner wall of the cylinder 2, allowing the sliders 8 to adjust the clamping plate 10 via the connecting posts 9. Springs 17 are fitted onto the outer walls of multiple limiting posts 16. A groove is provided on one side of the scraper 18. One side of the spring 17 contacts one side of the support plate 15, and the other side of the spring 17 contacts the inner wall of the groove in the scraper 18. This allows the distance between the scraper 18 and the support plate 15 to be adjusted by the magnitude of the centrifugal force generated by the rotation of the rotating post 13. The positioning makes the scraping operation more complete. The bottom of the pusher 6 is slidably connected to the top of the disc 3. The top of the shell 1 is provided with a liquid inlet 19, which allows the water-reducing agent to enter the device. One side of the disc 3 is in contact with the top of the shell 1, making the whole device more stable. The shell 1 is fixedly connected with an isolation plate 21, which creates two reaction chambers inside the shell 1, allowing different raw materials to react simultaneously. The outer wall of the rotating column 13 is fixedly connected with multiple stirring blocks 14, which makes the mixing inside the shell 1 more thorough. The top of the rotating column 13 is rotatably connected to the inner wall of the shell 1.

[0035] Working principle: When external feed pipes of different specifications are inserted into the cylinder 2, due to the presence of the pull rod 7, when the cylinder 5 is opened, the push block 6 can drive the two sliders 8 to adjust to the appropriate position on the top of the disc 3, so that the distance between the two clamping plates 10 can be adjusted according to the size of the feed pipe, thereby firmly clamping the feed pipes of different specifications, so that the raw materials can smoothly and stably enter the shell 1. The water-reducing agent is injected into the shell 1 through the liquid inlet 19. Then, the motor 12 located inside the support column 11 is turned on, so that the rotating column 13 drives multiple stirring blocks 14 to work, so that the internal mixing is fully and evenly. Due to the presence of the support plate 15, the scraper 18 moves synchronously in a circular motion with the rotating column 13. Due to the presence of the limiting column 16 and the spring 17, the scraper 18 can be adjusted to different positions to move in a circular motion according to different centrifugal forces. After the reaction in the reactor has been going on for a certain time, the plug 20 located inside the shell 1 is pulled out, so that the internal fluid flows out.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
