Description

Technical Field

[0001] This utility model relates to the field of fullerene production technology, specifically to a high-yield fullerene preparation device based on a multi-stage reaction. Background Technology

[0002] Fullerenes are the third allotrope of elemental carbon discovered. Any substance composed solely of carbon and existing in a spherical, elliptical, or tubular structure can be called a fullerene; fullerenes refer to a class of substances. Fullerenes have a structure similar to graphite, but while graphite contains only six-membered rings, fullerenes may contain five-membered rings. Relatively well-established methods for preparing fullerenes include the arc flash method, thermal evaporation method, combustion method, and chemical vapor deposition method.

[0003] Chinese Patent No. CN 217264864 U discloses a fullerene synthesis and preparation apparatus, comprising a main body including a mixing chamber and a combustion chamber. A valve is installed at the center of one side of the delivery pipe, an electric heating rod is installed around the mixing rod, a buffer chamber is installed below the vacuum chamber, a filter plate is installed inside the buffer chamber, a spray chamber is installed around the combustion chamber, a water storage chamber is installed below the spray chamber, and a flame nozzle is installed above the combustion chamber. In this fullerene synthesis and preparation apparatus, the vacuum chamber is first activated to draw air from the main body of the apparatus, reducing impurities such as air. The reaction gas enters the mixing chamber through the inlet pipe, is mixed, passes through the buffer chamber, is filtered, and then enters the combustion chamber. After high-temperature combustion with flame, fullerene is finally obtained. This improves the mixing effect and reaction efficiency, ensures the normal progress of the reaction process, and achieves the effects of circulating cooling and water resource reuse.

[0004] However, in the above technical solution, the gas is mixed by rotating the rotating shaft to drive the mixing rod to rotate. However, the mixing effect of the gas is limited by the rotation of the mixing rod alone, and the mixing rod needs a high rotation speed to improve its mixing effect. The increase in rotation speed will lead to a shorter gas residence time and reduce the contact time between gases. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a high-yield fullerene preparation device based on a multi-stage reaction.

[0006] The technical solution of this utility model is as follows: A high-yield fullerene preparation device based on a multi-stage reaction includes a mixing equipment body, which has a mixing chamber and a combustion chamber inside.

When the mixing component is in use, the Venturi tube, the dynamic mixer, and the static mixer form a three-stage mixing structure to guide and mix the airflow. ， The Venturi tube and the static mixer guide gas mixing through their own structure, while the dynamic mixer rotates the mixed gas through its rotating end.

[0007] Preferably, the mixing component also includes a vacuum pump connected to the main body of the mixing equipment. The air inlet end of the vacuum pump is connected to an air inlet pipe, and one end of the air inlet pipe is connected to the mixing chamber.

[0009] Preferably, the transmission component consists of a driving synchronous pulley, a driven synchronous pulley, and a synchronous toothed belt. The driving synchronous pulley and the driven synchronous pulley are respectively connected to the extension shaft and the support shaft, and the synchronous toothed belt meshes with the driving synchronous pulley and the driven synchronous pulley.

[0010] Preferably, the static mixing component consists of a sleeve, a connecting frame, and a helical blade. The sleeve is centered on the mixing chamber, the connecting frame is connected to the outside of the sleeve and the mixing chamber, and the helical blade is connected inside the sleeve.

[0011] Preferably, the spiral blades are connected to multiple inclined guide vanes.

[0012] Preferably, a water-cooling jacket is fitted on the outside of the combustion chamber.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0014] In this invention, the fuel and gas are initially mixed by accelerating the airflow through a Venturi tube. The dynamic mixing component downstream of the Venturi tube generates turbulence by rotating the mixing blades. The spiral blades further mix the gas and prolong the time the gas stays in the mixing chamber, eliminating local eddies and enhancing the mixing effect. The gas mixing effect is further improved by the three sets of mixing structures from front to back. Attached Figure Description
