Description

Technical Field

[0001] This utility model relates to the field of chemical technology, and in particular to a chemical reaction vessel. Background Technology

[0002] In the field of chemical production, the reactor is the core equipment for realizing chemical reactions, and its performance directly affects product quality, production efficiency, and energy consumption. With the continuous upgrading of chemical processes, higher requirements are placed on the mixing uniformity, material handling efficiency, and adaptability of the reactor. In particular, when dealing with materials with high viscosity, easy adhesion, or complex state changes during the reaction process, traditional reactors have gradually revealed many limitations. Traditional reactor stirring systems typically employ fixed-height agitators, making it difficult to flexibly adjust their stirring range and intensity according to changes in material level and reaction stages. When the material viscosity is high, the agitator often only operates in the central region of the reactor, leading to uneven mixing of materials between the upper and lower layers and incomplete local reactions. This not only affects product purity but may also pose safety hazards due to localized overheating. Furthermore, high-viscosity materials readily adhere to the reactor's inner wall during the reaction. If not cleaned promptly, this results in material waste, and the adhered material, exposed to the high-temperature reaction environment for extended periods, may deteriorate or coke, affecting the efficiency and quality of subsequent batches and increasing the difficulty of equipment cleaning and maintenance costs. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing traditional reaction vessels, such as the difficulty in flexibly adjusting the stirring range and intensity according to changes in material liquid level and differences in reaction stages. At the same time, high-viscosity materials are prone to adhering to the inner wall of the vessel during the reaction process. If not cleaned in time, this will result in material waste, and the adhered materials may deteriorate or coke if exposed to a high-temperature reaction environment for a long time. Therefore, this invention proposes a chemical reaction vessel.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A chemical reaction vessel includes a vessel body, a drive motor fixedly installed at the bottom of the vessel body, a transmission rod fixedly connected to the output end of the drive motor, a support arm fixedly connected to the outer wall of the transmission rod, a scraper fixedly connected to the end of the support arm away from the transmission rod, a wear-resistant tip fixedly connected to the side of the scraper near the inner wall of the vessel body, a stirring assembly that moves up and down axially connected to the transmission rod, and a vessel cover threadedly connected to the top of the vessel body.

[0005] Preferably, an arc block is fixedly connected to the side wall of the support arm, and a scraper is fixedly connected to the bottom of the arc block. The arc block and the scraper are used to scrape off the material at the bottom of the inner wall of the vessel and discharge it out of the vessel.

[0006] Preferably, the stirring assembly includes a sliding sleeve that is slidably connected to the outer wall of the transmission rod, a stirring rod that is fixedly connected to the outer wall of the sliding sleeve, a locking bolt that passes through and is threaded onto the outer wall of the sliding sleeve, and a U-shaped adapter block that is fixedly connected to the end of the stirring rod away from the sliding sleeve, the adapter block being slidably connected to the outer wall of the scraper.

[0007] Preferably, an extension plate is installed at the bottom of the stirring rod, the extension plate being used to increase the stirring area.

[0008] Preferably, a discharge pipe is connected through the outer wall of the vessel, and a valve is provided on the discharge pipe.

[0009] Preferably, a support frame is provided at the bottom of the vessel body, and the vessel body is placed on the support frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In use, this utility model can be equipped with a stirring component that can move up and down along the axis of the transmission rod. The operator can flexibly adjust the height of the stirring rod according to the changes in the liquid level of the material and the differences in the reaction stage. Then, it is fixed by locking bolts to ensure that the stirring range and intensity are precisely matched with the reaction requirements, which greatly improves the targeting and effectiveness of stirring and is conducive to promoting the full reaction of materials.

[0011] 2. When this utility model is in use, the support arm and scraper can be rotated synchronously by the transmission rod. The wear-resistant tip on the scraper can continuously scrape off the high-viscosity material adhering to the inner wall of the reactor, avoiding material residue and waste. At the same time, timely cleaning of the adhering material can prevent it from deteriorating and coking in the high-temperature reaction environment, ensuring the purity and quality of the reaction product.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Reference Figures 1-3 A chemical reaction vessel includes a vessel body 1, which serves as the main container for material reaction and has a cylindrical hollow structure. A drive motor 2 is fixedly installed at the bottom of the vessel body 1, which provides power for the operation of the entire device. It should be noted that the specific model and specifications of the drive motor 2 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here. In addition, all of them can be powered by external devices and controlled to turn on and off.

[0016] A transmission rod 3 is fixedly connected to the output end of the drive motor 2. The transmission rod 3 is vertically installed inside the vessel body 1 and can rotate around its own axis under the drive of the drive motor 2. A support arm 4 is fixedly connected to the outer wall of the transmission rod 3. The support arm 4 is horizontally installed and rotates synchronously with the transmission rod 3. A scraper 5 is fixedly connected to the end of the support arm 4 away from the transmission rod 3. The scraper 5 is installed along the height direction of the inner wall of the vessel body 1. A wear-resistant tip 6 is fixedly connected to the side of the scraper 5 closest to the inner wall of the vessel body 1. The wear-resistant tip 6 contacts the inner wall of the vessel body 1. When the scraper 5 rotates with the support arm 4, it can scrape off the material adhering to the inner wall of the vessel body 1. The wear-resistant tip 6 can improve the scraping effect and extend the service life of the scraper 5. A stirring assembly 7, which moves axially up and down, is slidably connected to the transmission rod 3. The stirring assembly 7 includes a sliding sleeve 11 slidably connected to the outer wall of the transmission rod 3. The sliding sleeve 11 can slide freely along the axial direction of the transmission rod 3, thereby adjusting the overall height of the stirring assembly 7. A stirring rod 13 is fixedly connected to the outer wall of the sliding sleeve 11. The stirring rod 13 is horizontally positioned and rotates together with the transmission rod 3 and the sliding sleeve 11 to stir the material inside the vessel 1. A locking bolt 12 is threaded through and connected to the outer wall of the sliding sleeve 11. After the stirring assembly 7 is adjusted to a suitable height, the locking bolt 12 is tightened to fix the sliding sleeve 11 relative to the transmission rod 3, thereby fixing the position of the stirring assembly 7. An adapter block 14 is fixedly connected to the end of the stirring rod 13 away from the sliding sleeve 11. The adapter block 14 is slidably connected to the outer wall of the scraper 5. The adapter block 14 provides support for the stirring rod 13, improving its stability, and allows it to slide smoothly along the scraper 5 when the stirring assembly 7 moves up and down, ensuring smooth adjustment. An extension plate 15 is installed at the bottom of the stirring rod 13. The extension plate 15 extends downward, which can increase the contact area between the stirring component 7 and the material, thereby improving the stirring efficiency. A discharge pipe 16 is connected through the outer wall of the vessel body 1. The discharge pipe 16 is used to discharge the material after the reaction is completed from the vessel body 1. A valve is installed on the discharge pipe 16, and the opening and closing of the discharge pipe 16 can be controlled by the valve. A circular arc block 9 is fixedly connected to the side wall of the support arm 4. The circular arc block 9 is adapted to the shape of the inner wall of the bottom of the vessel body 1. A scraper 10 is fixedly connected to the bottom of the circular arc block 9. The scraper 10 contacts the inner wall of the bottom of the vessel body 1. When the support arm 4 rotates, the circular arc block 9 and the scraper 10 rotate together, scraping off the material at the bottom of the inner wall of the vessel body 1 and pushing it toward the discharge pipe 16. This facilitates the complete discharge of the material from the vessel body 1 through the discharge pipe 16, reducing the residue of the material at the bottom of the vessel body 1. A support frame 17 is provided at the bottom of the vessel body 1. The vessel body 1 is placed on the support frame 17, which supports the vessel body 1 and improves the stability and safety of the vessel body 1. The top of the vessel body 1 is threadedly connected to a vessel cover 8, which is used to close the top opening of the vessel body 1. The threaded connection makes it easy to install and remove the vessel cover 8, and facilitates the addition of materials to the vessel body 1 or the maintenance of the interior of the vessel body 1.

[0017] Working principle: First, unscrew the lid 8 and add the required reaction materials into the vessel body 1. Then, close the lid 8 to ensure a seal. Start the drive motor 2, which drives the transmission rod 3 and support arm 4 to rotate. This causes the wear-resistant tip 6 on the scraper 5 to continuously scrape off the material adhering to the inner wall of the vessel body 1. Simultaneously, the stirring assembly 7 mixes and stirs the materials through the stirring rod 13 and the extension plate 15. The height of the sliding sleeve 11 can be adjusted by loosening the locking bolt 12. The adapter block 14 slides along the scraper 5 to maintain stability. After adjustment, the locking bolt 12 is fixed in position to adapt to the stirring requirements of different materials.

[0018] After the reaction is complete, open the valve of the discharge pipe 16. The scraper 10 at the bottom of the support arm 4 rotates and pushes the material at the bottom of the vessel 1 towards the discharge pipe 16, reducing residue. After the material is discharged, close the valve and stop the drive motor 2. When cleaning or maintenance is required, open the vessel lid 8 again. The wear-resistant tip 6 and the scraper 10 work together to efficiently remove scale from the inner wall and bottom. The support frame 17 ensures operational stability. The entire process integrates material stirring, reaction, discharge, and cleaning, resulting in a compact structure and convenient operation.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
