Description

Technical Field

[0001] This utility model relates to the technical field of stirring devices, specifically a high-temperature stirring device for polymer materials. Background Technology

[0002] Polymer materials can be classified into natural polymers and synthetic polymers based on their source. Natural polymers are macromolecular substances found in animals, plants, and other organisms, and can be further divided into natural fibers, natural resins, natural rubber, animal glues, etc. Synthetic polymers mainly refer to the three major synthetic materials: plastics, synthetic rubber, and synthetic fibers. They also include adhesives, coatings, and various functional polymers. Some polymer materials possess high-temperature resistance, requiring very high temperatures during production and processing to achieve the necessary raw material mixing and reaction. The unique structure, ease of modification, and ease of processing of polymer materials give them superior properties unmatched and irreplaceable by other materials, leading to their widespread use in science and technology, national defense, and various sectors of the national economy.

This invention provides a high-temperature stirring device for polymer materials. By utilizing the above-mentioned structure, this invention has the following beneficial effects: the use of scrapers and other structures facilitates the scraping of polymer materials adsorbed on the inner wall of the tank during stirring, preventing adsorption on the inner wall and improving the mixing effect while also facilitating cleaning of the inner wall of the tank.

[0004] However, the contact area between the stirring blades and the polymer material in the above documents is small, and the distance between the stirring blades is large, resulting in inadequate stirring of the polymer material. Secondly, the stirring structure cannot be separated from the stirring drum; the material is simply scraped off the inner wall of the stirring drum by a scraper, making it inconvenient to clean the stirring mechanism and the stirring drum. Therefore, it is necessary to propose a high-temperature stirring device for polymer materials to solve the above-mentioned problems. Utility Model Content

[0025] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0026] Please see Figures 1 to 4A high-temperature stirring device for polymer materials includes a heating chamber 1 with a stirring drum 101 installed inside, a sealing cover 102 installed on the upper end face of the stirring drum 101, and a stirring mechanism installed inside the stirring drum 101; a second driving mechanism is provided below the heating chamber 1, and a first driving mechanism is provided on the rear end face of the second driving mechanism.

[0027] The first drive mechanism includes a fixed frame 3, an electric slide rail 301 installed on the left and right sides of the front end face of the fixed frame 3, and a first connecting frame 302 slidably connected to the outer wall of the electric slide rail 301 and fixedly connected to the sealing cover 102.

[0029] In this embodiment: the sealing cover 102 is opened, and the polymer material is placed into the stirring drum 101. The polymer material in the stirring drum 101 can be heated by the heating chamber 1. At the same time, the polymer material in the stirring drum 101 can be stirred by the stirring mechanism. Specifically, the stirring shaft 2 drives multiple stirring plates 202 to rotate and stir the polymer material in the stirring drum 101. The multiple stirring plates 202 can increase the contact area with the polymer material, thereby improving the stirring efficiency of the polymer material. The bottom plate 203 can stir the polymer material at the bottom of the stirring drum 101 to avoid uneven stirring at the bottom. As the stirring shaft 2 rotates, the scraper 201 can rotate to scrape off the material adhering to the inner wall of the stirring drum 101.

[0030] Secondly, when it is necessary to clean the mixing drum 101 and the mixing mechanism, the two electric slide rails 301 synchronously drive the first connecting frame 302 to move upward, causing the first connecting frame 302 to drive the sealing cover 102 to move upward until the mixing mechanism is moved out of the mixing drum 101, thereby facilitating the cleaning and maintenance of the mixing mechanism and the mixing drum 101.

[0031] As a technical optimization of this utility model, the second drive mechanism includes two L-shaped plates 4 disposed on the outside of the heating chamber 1, a threaded rod 401 rotatably connected to the inside of one of the L-shaped plates 4, a motor 404 installed on the outer wall of one of the L-shaped plates 4 and fixedly connected to the threaded rod 401, and a second connecting frame 403 threadedly connected to the outer wall of the threaded rod 401 and fixedly connected to the heating chamber 1.

[0032] In this embodiment: the motor 404 is started, which drives the threaded rod 401 to rotate, causing the second connecting frame 403 to move the mixing drum 101 to the right, causing the mixing drum 101 and the mixing mechanism to be misaligned, thereby facilitating the cleaning of the mixing drum 101 and the mixing mechanism.

[0033] As a technical optimization of this utility model, the second driving mechanism also includes a slide rod 402 fixedly connected inside another L-shaped plate 4, and the slide rod 402 is slidably connected to the second connecting frame 403.

[0034] In this embodiment, the second connecting frame 403 can be moved stably by the slide bar 402.

[0035] As a technical optimization of this utility model, the bottom end of the mixing drum 101 is connected to a discharge pipe located between two L-shaped plates 4.

[0036] In this embodiment, the material inside the mixing drum 101 is easily discharged through the discharge pipe.

[0037] As a technical optimization of this utility model, the bottom end of the heating cavity 1 abuts against the inner walls of the two L-shaped plates 4.

[0038] In this embodiment: the bottom end of the heating cavity 1 abuts against the inner walls of the two L-shaped plates 4, and the heating cavity 1 can be supported by the two L-shaped plates 4.

[0039] As a technical optimization of this utility model, the fixing frame 3 is fixedly connected to the L-shaped plate 4 located at the rear.

[0040] In this embodiment: the fixing frame 3 is fixedly connected to the L-shaped plate 4 located at the rear, which can support the fixing frame 3.

[0041] As a technical optimization of this utility model, a controller 5 is installed on the outer wall of one of the L-shaped plates 4, and the stirring mechanism, electric slide rail 301 and motor 404 are all electrically connected to the controller 5.

[0042] In this embodiment, the controller 5 can control the stirring mechanism, the electric slide rail 301 and the motor 404 to work normally.

[0043] Working principle: First, the sealing cover 102 is opened by the first driving mechanism, and the polymer material is put into the stirring drum 101. Then, the sealing cover 102 is placed on the stirring drum 101 by the first driving mechanism. The heating ring in the heating chamber 1 can heat the polymer material in the stirring drum 101. At the same time, the stirring mechanism can stir the polymer material in the stirring drum 101. Specifically, the stirring shaft 2 drives multiple stirring plates 202 to rotate and stir the polymer material in the stirring drum 101. The multiple stirring plates 202 can increase the contact area with the polymer material, thereby improving the stirring efficiency of the polymer material. The bottom plate 203 can stir the polymer material at the bottom of the stirring drum 101 to avoid uneven stirring at the bottom. As the stirring shaft 2 rotates, it can drive the scraper 201 to rotate and scrape off the material adhering to the inner wall of the stirring drum 101. Then, the stirred polymer material is discharged through the discharge pipe.

[0044] Secondly, when it is necessary to clean the mixing drum 101 and the mixing mechanism, the two electric slide rails 301 synchronously drive the first connecting frame 302 to move upward, causing the first connecting frame 302 to drive the sealing cover 102 to move upward until the mixing mechanism moves out of the mixing drum 101. Then, the motor 404 is started, causing the motor 404 to drive the threaded rod 401 to rotate, causing the second connecting frame 403 to drive the mixing drum 101 to move to the right, causing the mixing drum 101 and the mixing mechanism to be misaligned, thus facilitating the cleaning and maintenance of the mixing mechanism and the mixing drum 101.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
