Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to an automatic feeding and metering reaction vessel. Background Technology

[0002] With the continuous development of production technology, higher requirements are being placed on the automation level and metering accuracy of reaction vessels. Although some existing reaction vessels possess certain automation functions, they still have limitations in feed metering. For example, when using simple flow meters, they are easily affected by material characteristics and flow states, leading to large metering errors; while using weighing metering methods suffers from inconvenient installation and high maintenance costs. Therefore, it is necessary to design an automated feed metering reaction vessel with a high degree of automation, high metering accuracy, and high safety and reliability to meet the needs of various industries for high-quality product production.

A baffle plate is provided on the inner wall of the lower reactor body to fit against the inner wall. This invention allows for convenient cleaning of residues from the inner wall of the reactor.

[0004] Although the equipment described in the aforementioned literature can be cleaned, its structure is relatively simple, making it ineffective for cleaning. Furthermore, the temperature control components are not efficient enough, and the feeding process is inconvenient, resulting in a lack of flexibility and convenience in its use, and thus low practicality.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This utility model provides an automatic feeding and metering reactor. The equipment is equipped with an automatic feeding device, which facilitates the control of material feeding. In many chemical reactions, the ratio between reactants has a crucial impact on the reaction process and the quality of the products. The automatic feeding and metering component can add various raw materials according to a preset precise ratio, ensuring the reaction proceeds according to the optimal stoichiometric ratio. Traditional manual feeding methods require operators to constantly monitor and adjust the feed, which is time-consuming and prone to human error. The automatic feeding and metering component, however, can operate continuously and stably throughout the entire reaction process, eliminating the need for frequent manual intervention. Intervention significantly shortens the reaction cycle and improves production efficiency. The automated feeding and metering system ensures that the amount of raw materials added and the feeding conditions are basically consistent for each production batch, thereby guaranteeing the stability of product quality and consistency between batches. The screw rod driven by the first motor rotates to transport the raw materials upwards, and then they are transported to the reaction vessel through the conveying pipe. The metering device can measure the conveyed raw materials, which is convenient for controlling the feeding. In addition, the upper end of the feeding hopper is equipped with a cover plate that is easy to open and close. Rotating the pin will allow it to pass through the card plate and be placed into the card slot plate for quick fixation. Conversely, it can be opened easily to facilitate the workers to pour the materials.

[0020] 2. This utility model provides an automatic feeding and metering reactor. The equipment is equipped with a stirring and cleaning device, which enables automatic cleaning. During a chemical reaction, reactants, products, or byproducts may adhere to the inner wall of the reactor. If these substances are not removed in time, they may detach and mix into the reaction system, becoming impurities and affecting the purity and quality of the product. The brush plate effectively scrapes the inner wall when the stirring component rotates, removing these deposits promptly and ensuring the purity of the reaction system. Deposits on the inner wall may hinder heat transfer and mass exchange, affecting the uniformity of the reaction. The presence of the brush plate keeps the inner wall clean. This allows the reactants to fully contact the inner wall, ensuring uniform heat transfer and improving reaction uniformity, which in turn helps improve product quality. Corrosion of the inner wall often starts locally and will gradually worsen if not addressed promptly. Regular cleaning of the inner wall can prevent the development of localized corrosion, protect the metal structure of the reactor, and make it more durable. The rotating rod, driven by a second motor, rotates, causing the stirring rod, which is fixed by a connecting sleeve, to rotate as well, thereby stirring the materials inside the reactor. In addition, a cleaning brush is installed at one end of the stirring rod, which rotates along with the brush plate as it rotates, facilitating scraping and cleaning of the inner wall of the reactor.

[0021] 3. This utility model provides an automatic feeding and metering reactor. The equipment is equipped with a temperature control device, which facilitates the control of the reactor's temperature. Temperature has a significant impact on the rate of chemical reactions. For many reactions, increasing the temperature increases the kinetic energy of reactant molecules, causing them to collide more frequently and violently, thereby accelerating the reaction rate. The temperature control component can precisely control the temperature inside the reactor within the optimal range according to the needs of different reactions, allowing the reaction to proceed at a suitable rate, shortening the reaction time, and improving production efficiency. In some chemical reactions, it is necessary to strictly control the degree of reaction to ensure product quality and yield. By precisely controlling the temperature, the reaction can proceed according to a predetermined schedule. The rate and extent of the reaction are controlled to avoid over- or under-reaction, thereby improving the repeatability and stability of the reaction. Different chemical reactions have different temperature requirements. Some reactions need to be carried out at low temperatures to prevent side reactions or maintain the activity of reactants, while others need to be started or carried out rapidly at high temperatures. The temperature control component can be precisely adjusted over a wide temperature range to meet the specific temperature requirements of various reaction types. The heating element is powered by a power supply and heats up, which is then transferred to the inner cylinder through a heat conduction plate. The temperature inside the cylinder is monitored in real time by a temperature sensor to maintain a suitable temperature inside the vessel and promote reaction efficiency. In addition, a heat insulation layer is set to prevent burns from external high temperatures. Attached Figure Description

The brush plate can effectively scrape the inner wall when the stirring component rotates, removing these deposits in time and ensuring the purity of the reaction system. Deposits on the inner wall may hinder heat transfer and mass exchange. The presence of a brush plate affects the uniformity of the reaction. It keeps the inner wall clean, allowing reactants to fully contact the inner wall and ensuring uniform heat transfer, thus improving reaction uniformity and product quality. Corrosion of the inner wall often starts locally and will gradually worsen if not addressed promptly.

The temperature control unit can precisely control the temperature inside the reactor within the optimal range according to the needs of different reactions, allowing the reaction to proceed at a suitable rate, shortening the reaction time, and improving production efficiency. In some chemical reactions, it is necessary to strictly control the extent of the reaction to ensure product quality and yield. By precisely controlling the temperature, the reaction can proceed at a predetermined rate and extent, avoiding over- or under-reaction, thereby improving the repeatability and stability of the reaction. Different chemical reactions have different temperature requirements.
