Abstract
Description
Technical Field

[0002] Stirring reactor is a common industrial equipment, used for mixing, dissolving, chemical reaction and other processes. This equipment usually consists of containers, stirring devices, heating / cooling systems, control systems and other parts. It is widely used in chemical, pharmaceutical, food and other industries to produce various chemical products, medicines, foods, etc. In industrial production, stirring reactor can improve reaction efficiency, ensure uniform reaction, control reaction temperature, and thus ensure product quality. At the same time, through the automatic control system, operators can easily monitor and adjust the reaction process, improve production efficiency and safety.
[0003] For example, the patent with publication number CN216260717U specifically discloses a wall-scraping stirring reactor, in which a mounting groove is opened on the side wall of the shell of a stirring plate, and a scraper is set by using a spring group and a movable block. The scraper adheres to the inner wall of the reactor under the push of the spring group and the movable block. While the stirring plate stirs the material, the scraper scrapes the inner wall of the reactor.
[0004] In the above patent, the device sets a coaxial scraper and a stirring plate so that the scraper scrapes the inner wall of the reactor while the material is stirred. However, when the viscosity of the material is high, the resistance encountered by the scraper during rotation also increases. However, since the scraper and the stirring plate are coaxially set, the stirring speed of the stirring plate located in the inner layer will also be affected, which may lead to reduced stirring efficiency. Moreover, since the stirring speed of the inner stirring plate is affected, the material may be unevenly stirred, affecting the uniformity of the reaction and the quality of the product. Therefore, it is necessary to provide a stirring reactor with high stirring efficiency to solve the above problems.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0021] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.
[0022] like Figure 1-Figure 2 As shown, the present application provides a stirring reactor, comprising a processing platform 1, which is arranged in a production workshop of a chemical plant, and a reactor 2 is fixedly installed on one side of the processing platform 1, and the reactor 2 is used to stir and blend chemical materials, and an opening 21 is arranged on the reactor 2, and a feeding device 11 is arranged on the processing platform 1, and one end of the feeding device 11 is connected to the opening 21, and is used to transport materials into the reactor 2;
[0023] A sampling device 5 is provided on the outside of the reactor 2. The sampling device 5 includes three groups of sampling valves 51. The three groups of sampling valves 51 are provided at different heights on the outer wall of the reactor 2 to sample and check the materials at different heights in the reactor 2, which is helpful to monitor the material status at different positions during the reaction process. Scale marks 52 are provided between the three groups of sampling valves 51 to help operators accurately record the sampling positions at different heights, so as to more conveniently monitor and compare the sampling data at different time points.
[0024] like Figure 1-Figure 3As shown, a stirring assembly 3 is provided in the reactor 2, and the stirring assembly 3 is used to stir the materials in the reactor 2 so that the materials inside are blended. The stirring assembly 3 includes a crossbeam 31 fixed on the reactor 2, and a first motor 32 is fixedly installed on the top of the crossbeam 31. The output end of the first motor 32 passes through the crossbeam 31 and is installed with a stirring shaft 321. A plurality of stirring blades 33 are fixedly installed on the stirring shaft 321. The stirring blades 33 are suitable for rotating under the drive of the first motor 32, so as to stir the materials inside the reactor 2.
[0025] A second motor 4 is installed on the top of the first motor 32, and a connecting shaft 41 is installed on the output end of the second motor 4. The interior of the connecting shaft 41 is set to be hollow, so that the connecting shaft 41 is suitable for sleeve connection on the outside of the stirring shaft 321, and there is a certain gap between the two, so that when the stirring shaft 321 and the connecting shaft 41 rotate, the two will not affect each other;
[0026] Two sets of outer frames 42 are provided at the bottom of the connecting shaft 41, and two sets of arc-shaped scrapers 43 are fixedly installed between the two sets of outer frames 42. A scraper 431 is provided on one side of the scraper 43 close to the inner wall of the reactor 2. The scraper 431 is used to continuously scrape the residual material on the inner wall of the reactor 2, and the scraper 431 is made of a flexible material so that it will not damage the inner wall of the reactor 2 when scraping the material.
[0027] The interior of the outer frame 42 is hollow, and a water inlet hole 421 is provided at the bottom where the outer frame 42 is connected to the connecting shaft 41. The water inlet hole 421 is suitable for being rotatably connected to a water pipe in an external water pump, and is used to introduce clean water or detergent into the interior of the outer frame 42. At the same time, a plurality of groups of nozzles 44 are provided on one side of the outer frame 42 close to the inner wall of the reactor 2. The nozzles 44 are used to spray clean water onto the inner wall of the reactor 2, thereby improving the scraping efficiency of the scraper 43.
[0028] When the reactor 2 is working, the first motor 32 drives the stirring shaft 321 to rotate, and then the stirring blades 33 are rotated synchronously, so that the material inside the reactor 2 is stirred. When the viscosity of the material is too high, the scraper 43 is driven by the second motor 4 to rotate, so that the material adhering to the inner wall of the reactor 2 is continuously scraped off, ensuring that the material in the reactor 2 can be fully stirred and mixed, thereby improving production efficiency and product quality.
[0029] In summary, the device avoids mutual interference by setting up a stirring shaft 321 and a connecting shaft 41 that rotate independently of each other. At the same time, the flexible material design of the scraper 431 ensures that the scraper 43 does not damage the inner wall of the reactor 2 when scraping residual materials. At the same time, by setting up the nozzle 44, the cleaning work of the device is simplified, which helps to improve production efficiency and keep the production environment clean and hygienic.
