Description
Technical Field
[0001] This utility model relates to the field of chemical reaction technology, specifically to a gas-liquid mixing reactor. Background Technology
[0002] In a broad sense, a reaction vessel is a container that carries out physical or chemical reactions. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. Reactors 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] Existing gas-liquid mixing reactors have some shortcomings. On the one hand, the mixing effect of gas and liquid is not good. Usually, gas is directly introduced into liquid, resulting in uneven gas distribution and difficulty in fully contacting liquid, leading to low reaction efficiency. On the other hand, for some gas-liquid mixing reactions that require the addition of catalyst particles, the dispersion effect of catalyst particles in liquid is poor, and they cannot mix with liquid quickly and uniformly, affecting the reaction and product quality. Utility Model Content
[0004] To address these issues, this invention provides a gas-liquid mixing reactor to solve two problems: firstly, the mixing effect of gas and liquid is poor, as gas is usually directly introduced into the liquid, resulting in uneven gas distribution and difficulty in fully contacting the liquid, leading to low reaction efficiency; secondly, for some gas-liquid mixing reactions that require the addition of catalyst particles, the dispersion effect of the catalyst particles in the liquid is poor, and they cannot mix with the liquid quickly and evenly, affecting the reaction process and product quality.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas-liquid mixing reactor, comprising a reactor body, wherein a mixing mechanism is provided inside the reactor body;
[0006] The mixing mechanism includes a rotating rod located inside the reactor body. Multiple stirring blades are fixedly connected to the outside of the rotating rod. The rotating rod passes through the reactor body and is connected to it via a bearing. The rotating rod is also connected to the bottom of the reactor body via a bearing. A groove is formed on one side of the rotating rod, and a square shell is located inside the groove. Two round tubes are fixedly installed at the bottom of the square shell, and a push rod is fixedly connected to the top of the square shell. A rotary joint is connected to one side of the push rod. A gas pump is fixedly installed on the top of the reactor body, and a connecting hose is fixedly connected to the output end of the gas pump. One end of the connecting hose is fixedly connected to the rotary joint. An electric push rod is fixedly installed on one side of the reactor body, and a connecting plate is fixedly connected to the output end of the electric push rod. One end of the push rod is connected to the connecting plate via a bearing.
[0007] Preferably, a fixed frame is fixedly provided on the top of the reactor body, a motor is fixedly provided on the top of the fixed frame, a drive shaft is fixedly connected to the output end of the motor, one end of the drive shaft is connected to the top of the reactor body through a bearing, a first gear is fixedly sleeved on the outside of the drive shaft, and a second gear is fixedly sleeved on the outside of the rotating rod, the second gear meshing with the first gear.
[0008] Preferably, the reactor body is provided with a material dispersing assembly, which includes an upper cover plate, the upper cover plate is fixedly disposed at the top of the inner cavity of the reactor body, the bottom of the upper cover plate is provided with a rotating disk, the rotating disk is fixedly disposed outside the rotating rod, and a material conveying pipe is fixedly connected to the top of the upper cover plate, the material conveying pipe extending out of the reactor body.
[0009] Preferably, a feed pipe is fixedly provided on the top of the reactor body.
[0010] Preferably, a feed pipe is fixedly provided at the bottom of the reactor body.
[0011] Preferably, the bottom of the reactor body is provided with multiple support columns.

[0014] The present invention has the following advantages:
[0015] 1. By setting up a mixing mechanism, the depth of the round tube inserted into the liquid can be adjusted by an electric push rod according to the liquid level. The gas is delivered to the push rod through a connecting hose and a rotary joint by a gas pump, and then discharged through the round tube at the bottom of the square shell and comes into contact with the liquid. At the same time, the motor drives the rotating rod to rotate, which in turn drives the square shell and the round tube to rotate. Combined with the stirring of the stirring blades, the gas can be more evenly distributed in the liquid, which greatly improves the mixing effect of gas and liquid and speeds up the reaction.
[0016] 2. The reactor body is equipped with a material dispersing assembly. Catalyst particles are conveyed through a conveying pipe. The rotating rod drives the rotating disk to rotate. The rotation of the rotating disk generates centrifugal force to diffuse the catalyst particles. The catalyst particles contact the upper cover plate and fall down, thus scattering into the liquid. This allows the catalyst particles to mix with the liquid quickly and evenly, improving reaction efficiency and product quality. Attached Figure Description
