Description

Technical Field

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

[0002] In a broad sense, a reaction vessel is a container where physical or chemical reactions occur. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. Reaction vessels are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries as pressure vessels to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation.

[0003] Patent CN218167012U discloses a chemical reactor, which includes a reactor body and a support base installed at the bottom of the reactor body. After heating, the threaded sleeve can act as a heat conductor to transfer heat to the raw material feeding pipe. The device has an electromagnetic valve and a temperature sensor electrically connected to a controller, and the controller is electrically connected to an external power supply. Thus, the electromagnetic valve remains closed until the set temperature is reached, allowing continuous heating of the additive. Once the set temperature is reached, the electromagnetic valve opens, and the additive is added into the reactor.

[0004] However, the existing device directly adds the additive into the reactor through the raw material feeding pipe, and the process is coordinated with structures such as hot air blowers, air inlets, and ventilation ducts to heat the additive to ensure the catalytic effect. However, when the additive is added into the feeding pipe, the feeding pipe will inevitably be connected to the external environment. This not only makes it easy for dust and impurities from the external environment to enter the reactor, but also causes gases that may contain harmful substances generated in the reactor to be discharged from the feeding pipe, thereby affecting personnel health and the environment. Therefore, a chemical reactor is proposed to solve the problem that existing reactors cannot safely and quickly add catalysts. Utility Model Content

[0005] (a) Technical problems to be solved

[0015] (III) Beneficial Effects

[0016] 1. This chemical reactor places the fixed catalyst required for the reaction into a storage tank. When catalyst needs to be added, there is no need to open the feed pipe. The feed column inside the fixed shell is rotated 180 degrees by a stepper motor, and the feed trough in the storage tank is rotated to connect with the discharge port, allowing the catalyst to enter the reactor to promote the reaction. The feed trough in the storage tank continues to receive catalyst for subsequent use. This process is repeated to avoid the release of internal gas, thus solving the problem of the difficulty in safely and quickly adding catalyst in existing reactors.

[0017] 2. This chemical reactor, through the combination of a feeding column, a feeding trough, a stepper motor, and other structures, adds catalyst by rotating. The catalyst is collected by the guide slope and guide trough, and then the electric push rod in the fixed seat drives the pressing column to move downward to press the catalyst, so that it quickly enters the feeding trough, achieving the purpose of rapid feeding and facilitating the stable rotation of the feeding column to add catalyst later.

[0025] Furthermore, a slot is provided at the joint between the storage box 5 and the fixed shell 6, which communicates with the fixed shell 6. A part of the feeding column 8 is located in the inner cavity of the slot, and the inner wall of the feeding groove 9 is very smooth.

[0026] Furthermore, when the feeding column 8 is in its initial position, the discharge port 7 is connected to one of the feeding troughs 9, the other feeding trough 9 is connected to the storage box 5, the discharge port 7 passes through the cover 2 and is connected to the reactor 1, the stepper motor 10 can rotate 180 degrees once it is turned on, the output shaft of the stepper motor 10 passes through the fixed shell 6 and is fixedly connected to the feeding column 8.

[0027] Furthermore, the inner cavity of the storage box 5 is provided with a guide slope 12, and the bottom of the guide slope 12 is provided with a guide groove 13. The guide groove 13 communicates with the feeding groove 9 inside the storage box 5, and the surfaces of the guide slope 12 and the guide groove 13 are very smooth.

[0028] Furthermore, the pressing mechanism 11 includes a fixed seat 111 fixedly connected to the inner wall of the storage box 5. An electric push rod 112 is provided in the inner cavity of the fixed seat 111, and a pressing column 113 is provided at the bottom of the fixed seat 111. The electric push rod 112 is fixedly connected to the pressing column 113. A ramp 114 is provided on one side of the top of the fixed seat 111. When adding catalyst by rotating the feeding column 8, feeding trough 9, stepper motor 10 and other structures, the catalyst is gathered by the guide ramp (12) and guide trough 13. Then, the electric push rod 112 in the fixed seat 111 drives the pressing column 113 to move downward to press the catalyst, so that it quickly enters the feeding trough 9, thereby achieving the purpose of rapid feeding and facilitating the subsequent stable rotation of the feeding column 8 to add catalyst.

[0031] Working principle: When using this chemical reactor, the raw materials to be reacted are introduced into the feed pipe 3 and then closed. The stirring mechanism 14 stirs the raw materials in the reactor 1 to improve the reaction efficiency. At the same time, the cover plate 16 is opened in advance, and the fixed catalyst required for the reaction is placed in the storage tank 5. When the catalyst needs to be added, there is no need to open the feed pipe 3. The stepper motor 10 drives the feeding column 8 in the fixed shell 6 to rotate 180 degrees, and the feeding trough 9 in the storage tank 5 is rotated to communicate with the discharge port 7, so that the catalyst enters the reactor 1 to promote the reaction. The feeding trough 9 in the storage tank 5 continues to receive the catalyst for subsequent use. This process is repeated to avoid the internal gas from being released, which solves the problem of the existing reactors being unable to safely and quickly add catalyst.
