Description

Technical Field

[0001] This utility model relates to the field of stabilizer preparation technology, and in particular to a reaction vessel for preparing an environmentally friendly stabilizer. Background Technology

[0002] Environmentally friendly stabilizers, as a type of green additive, are widely used in the processing of materials such as plastics and rubber. By replacing traditional stabilizers containing heavy metals (such as lead salts and cadmium salts), they reduce harm to the environment and human health while ensuring material stability. The preparation process of environmentally friendly stabilizers usually requires mixing and reacting various raw materials (including solid powders such as calcium stearate and zinc oxide, and liquid additives such as polyols) in a reaction vessel to ultimately form a product with stabilizing properties.

[0003] However, traditional environmentally friendly stabilizer preparation reactors have significant drawbacks in the feeding process: operators must directly add raw materials containing a large amount of powder into the reactor. Due to the light weight and high fluidity of the powder particles, they are easily stirred up by the airflow inside the reactor during the fall. Some powder will adhere to the inner wall of the reactor, the top of the reactor lid, or be suspended in the air. This not only leads to waste of raw materials and inaccurate mixing ratios, affecting the uniformity of the reaction, but also increases the difficulty of cleaning the reactor. Long-term accumulation may cause blockage of equipment pipelines and even affect the safety of the production environment. In order to solve the above problems, this utility model proposes an environmentally friendly stabilizer preparation reactor. Utility Model Content

[0004] The main objective of this invention is to provide a reaction vessel for preparing environmentally friendly stabilizers, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An environmentally friendly stabilizer preparation reactor includes a reactor and a lid. A mounting frame and a stirring motor are fixedly connected to the upper end of the lid. A stirrer is fixedly connected to the output shaft of the stirring motor. The reactor is provided with a material guiding mechanism for guiding materials. The material guiding mechanism includes multiple feeding hoppers set on the lid. Each feeding hopper is provided with a sealing cover. A material guiding pipe is sleeved on the side wall of the feeding hopper. Multiple material dropping holes are opened at the lower end of the material guiding pipe. The mounting frame is provided with a drive mechanism for driving the material guiding pipe to rise and fall.

[0006] Preferably, the driving mechanism includes a second motor fixedly connected to the top of the mounting frame, a threaded rod fixedly connected to the output end of the second motor, a lifting ring provided on the side wall of the threaded rod, a horizontal plate fixedly connected to the side wall of the guide tube, and the horizontal plate fixedly connected to the upper end of the lifting ring.

[0007] Preferably, the upper end of the sealing cover is rotatably connected to a rotating shaft, and a second scraper is installed on the side wall of the rotating shaft through a second connecting plate.

[0008] Preferably, a sprocket is fixedly connected to the side wall of the rotating shaft, and a chain is provided on multiple sprockets. A first motor is fixedly connected to the bottom of the mounting frame, and the output shaft of the first motor is fixedly connected to the upper end of the adjacent rotating shaft.

[0009] Preferably, the stirrer sidewall is fixedly connected to two first connecting plates, and a first scraper is fixedly connected to both first connecting plates.

[0010] Preferably, a fixing plate is fixedly connected to the inner wall of the kettle lid, and the lower end of the threaded rod is rotatably connected to the upper end of the fixing plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This device is equipped with a material guiding mechanism. Through the small diameter design of the material guiding pipe, the inclined distribution of the material dropping holes, and the lifting and adjusting function, the disturbance of powder and airflow is reduced from both the material feeding path and distance, reducing adhesion and waste, and greatly improving the utilization rate of raw materials. This device is equipped with a drive mechanism. The screw rod is driven to rotate by a second motor, which can drive the lifting ring and the horizontal plate to move up and down, thereby realizing the lifting and lowering of the guide tube. The dropping position can be flexibly adjusted so that the powder is closer to the liquid surface or the bottom material, reducing the falling distance and reducing the risk of powder being thrown up. This device is equipped with a chain and sprocket, and uses chain and sprocket transmission. A single first motor can drive multiple second scrapers to work synchronously, eliminating the need for repeated drive components and reducing equipment costs and energy consumption. This device is equipped with a second scraper and a first scraper. The rotating second scraper and the first scraper reduce material residue, reduce the difficulty of subsequent cleaning, and extend the service life of the equipment. Attached Figure Description

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figure 1-4 As shown, an environmentally friendly stabilizer preparation reactor includes a reactor 1 and a lid 2. The reactor 1 has a heating jacket on its side wall (shown in the figure), a drain pipe at the lower end of the reactor 1 (shown in the figure), and an inlet pipe on the lid 2 (shown in the figure). A mounting bracket 5 and a stirring motor 6 are fixedly connected to the upper end of the lid 2. A stirrer 3 is fixedly connected to the output shaft of the stirring motor 6. The reactor 1 is provided with a material guiding mechanism, which includes multiple feed hoppers 4 set on the lid 2. Each feed hopper 4 is provided with a sealing cover 10. A material guiding pipe 7 is sleeved on the side wall of the feed hopper 4, and multiple discharge holes 22 are opened at the lower end of the material guiding pipe 7.

[0016] The mounting frame 5 is equipped with a drive mechanism for driving the guide tube 7 to rise and fall. The drive mechanism includes a second motor 18 fixedly connected to the top of the mounting frame 5. A threaded rod 19 is fixedly connected to the output end of the second motor 18. A lifting ring 20 is provided on the side wall of the threaded rod 19. The lifting ring 20 is threadedly connected to the threaded rod 19. A horizontal plate 17 is fixedly connected to the side wall of the guide tube 7. The horizontal plate 17 is fixedly connected to the upper end of the lifting ring 20.

[0017] In this utility model, a rotating shaft 14 is rotatably connected to the upper end of the sealing cover 10. A second scraper 15 is installed on the side wall of the rotating shaft 14 through a second connecting plate 16. The second scraper 15 is attached to the inner wall of the feed hopper 4. Its rotation can scrape off the powder adhering to the inner wall of the feed hopper 4, avoiding powder residue and waste, and at the same time accelerating the flow speed of the powder to the feed pipe 7, improving the feeding efficiency.

[0018] In this invention, a sprocket 13 is fixedly connected to the side wall of the rotating shaft 14. A chain 12 is provided on multiple sprockets 13. The meshing details of the chain 12 and the sprocket 13 are not shown in the figure, but in reality, the two mesh. A first motor 11 is fixedly connected to the bottom of the mounting bracket 5. The output shaft of the first motor 11 is fixedly connected to the upper end of the adjacent rotating shaft 14. The chain 12 is driven by a single first motor 11, which drives multiple sprockets 13 and rotating shafts 14 to rotate synchronously. There is no need to configure a separate drive assembly for each rotating shaft 14, which simplifies the structure, reduces production costs, and ensures the consistency of the actions of multiple second scrapers 15.

[0019] In this invention, two first connecting plates 8 are fixedly connected to the side wall of the stirrer 3, and a first scraper 9 is fixedly connected to both first connecting plates 8. The first scraper 9 is attached to the inner wall of the reactor 1, and can scrape off the material adhering to the reactor wall when the stirrer 3 rotates, ensuring that the raw materials fully participate in the reaction, improving the uniformity of the product, and reducing the difficulty of subsequent cleaning.

[0020] In this invention, a fixing plate 21 is fixedly connected to the inner wall of the lid 2, and the lower end of the threaded rod 19 is rotatably connected to the upper end of the fixing plate 21, which can prevent the lower end of the threaded rod 19 from being suspended.

[0021] During use, the operator adds the main stabilizer, auxiliary stabilizer, and carrier into the equipment according to the formula. The powder can be fed into the reactor 1 through multiple feed hoppers 4, and the liquid can be fed through the liquid inlet pipe. When feeding, the powder enters the sleeved guide pipe 7 from the feed hopper 4. The small diameter design of the guide pipe 7 slows down the falling speed of the powder. At the same time, the multiple dropping holes 22 at its lower end are inclined to guide the powder to fall obliquely, avoiding the airflow impact when falling vertically in a concentrated manner, and significantly reducing the powder from being thrown up. If there is powder adhering to the inner wall of the feed hopper 4, the first motor 11 drives the chain 12 and sprocket 13 to rotate, which drives the rotating shaft 14 and the second scraper 15 to rotate, which can scrape the residual powder into the guide pipe 7, ensuring that the raw materials are fully utilized. Alternatively, depending on the liquid level or bottom material height in the reactor, the second motor 18 starts and drives the threaded rod 19 to rotate, causing the lifting ring 20 to drive the guide pipe 7 to rise and fall along the side wall of the feed hopper 4 via the horizontal plate 17. When the lower end of the guide pipe 7 approaches the liquid level or bottom material, the falling distance of the powder is shortened, further reducing contact disturbance with the air and almost eliminating any lifting phenomenon. If it is necessary to adjust the feeding position, the threaded rod 19 is driven in the reverse direction (the output shaft of the second motor 18 is reversed) to lift the guide pipe 7, making the operation flexible. At the same time, the stirring motor 6 drives the stirrer 3 to rotate, which, together with the first scraper 9, scrapes off the material on the reactor wall, so that the added powder is quickly mixed with other raw materials, ensuring uniform reaction.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
