Description

Technical Field

[0001] This invention belongs to the field of reaction apparatus technology, and particularly relates to a reaction apparatus for the synthesis of 2-pentylanthraquinone. Background Technology

[0002] 2-Pentylanthraquinone is a compound that exhibits superior performance in hydrogen peroxide production due to its high stability, good compatibility with working solutions, and high catalytic efficiency. 2-Pentylanthraquinone is also a major intermediate and raw material for the production of ultrapure hydrogen peroxide, degradable resins, dyes, and photosensitive compounds.

[0003] The existing two-step method for preparing 2-pentylanthracene, with publication number CN 107602368 B, requires the raw materials to be added into a high-pressure reactor and stirred to allow the raw materials to react.

[0004] The existing stirring devices for reactors mostly consist of a stirring rod installed at the central axis of the reactor, with multiple stirring blades mounted on the stirring rod. The raw materials are stirred by the rotation of the stirring rod and stirring blades. However, the rotation of the stirring rod and stirring blades will generate centrifugal force on the raw materials, causing the heavier raw materials to be thrown near the side wall of the reactor, resulting in uneven distribution of the raw materials and uneven reaction between the reactor axis and the raw materials on the side wall of the reactor. Summary of the Invention

[0005] The purpose of this invention is to provide a reaction apparatus for the synthesis of 2-pentylanthraquinone, which aims to solve the problem of uneven reaction of raw materials between the axis of the reactor and the side wall of the reactor when the stirring rod and stirring blades are rotating.

A discharge pipe is connected to the bottom of the reaction vessel, and a first check valve is installed on the discharge pipe. The sealing cover is plugged into the open end of the reaction vessel. The first rotating disk is rotatably connected to the sealing cover and has a guide groove. The guide slider is slidably connected to the guide groove. The stirring shaft is rotatably connected to the guide slider and passes through the guide slider. A clearance groove for avoiding the stirring shaft is provided at the end of the first rotating disk near the reaction vessel. Multiple stirring blades are installed on the stirring shaft. The motion trajectory adjustment mechanism and the rotating assembly are both located on the sealing cover. The motion trajectory adjustment mechanism drives the first rotating disk to rotate and also changes the revolution radius of the stirring shaft. The rotating assembly drives the stirring shaft to rotate by changing the revolution radius of the stirring shaft.

[0007] In a further technical solution, a sealing groove is provided on the sealing cover at the guide groove, a sealing plate is slidably connected to the sealing groove, and the stirring shaft is rotatably connected to the sealing plate.

[0008] A further technical solution includes a second rotating disk, a rotating sleeve, a main shaft, and a reverse drive assembly. The second rotating disk is rotatably connected to the sealing cover, and a quadrilateral trajectory guide groove is provided on the second rotating disk. The upper end of the stirring shaft extends into the quadrilateral trajectory guide groove, and the stirring shaft slides into the quadrilateral trajectory guide groove. The rotating sleeve is fixed on the second rotating disk and passes through the sealing cover. The main shaft is fixed on the first rotating disk and passes through the rotating sleeve. The reverse drive assembly is provided on the sealing cover and is used to drive the first rotating disk and the second rotating disk to rotate in opposite directions.

[0009] A further technical solution includes a reverse drive assembly comprising a third rotating disk, an internal gear ring, a first drive shaft, a third gear, an L-shaped fixing frame, a second drive shaft, a second motor, and a transmission assembly. The first drive shaft is rotatably connected to the sealing cover. A first gear and a second gear are fixed to the first drive shaft. The third rotating disk is fixed to the upper end of the main shaft. The internal gear ring is fixed to the third rotating disk and meshes with the first gear. The third gear is fixed to the rotating sleeve and meshes with the second gear. The L-shaped fixing frame and the second motor are both fixed to the sealing cover. The second drive shaft is rotatably connected to the L-shaped fixing frame. The rotating end of the second motor is connected to the second drive shaft. The transmission assembly is disposed on the sealing cover, and the second drive shaft is connected to the third rotating disk via the transmission assembly.

[0010] In a further technical solution, the transmission assembly includes a first pulley, a belt, and a second pulley. The first pulley and the second pulley are respectively fixed on a third rotating disk and a second transmission shaft, and the first pulley and the second pulley are connected by belt drive.

[0011] In a further technical solution, the transmission assembly includes transmission gears, and transmission gears are fixed on both the third rotating disk and the second transmission shaft, with the two transmission gears meshing together.

[0012] In a further technical solution, the rotating assembly includes a rack and a fourth gear. The rack is fixed on the first rotating disk, and the fourth gear is fixed on the upper end of the stirring shaft and meshes with the rack. A gap is provided between the first rotating disk and the second rotating disk for mounting the rack and the fourth gear.

[0013] In a further technical solution, multiple stirring blades are installed on the stirring shaft, and the stirring blades are set at an angle with the horizontal plane. The stirring blades can generate an upward or downward pushing force on the raw materials by rotating.

[0014] A further technical solution is provided, wherein an addition pipe is fixed on the reaction vessel, the addition pipe is connected to the reaction vessel, a second check valve is installed on the addition pipe, an electric heating jacket is fixed on the side wall of the reaction vessel, and a temperature sensor is installed inside the reaction vessel.

At least two winding sleeves and ropes are provided.

[0016] This invention provides a reaction apparatus for the synthesis of 2-pentylanthraquinone. Raw materials are fed into a reaction vessel, and a sealing cap is placed on top. A motion trajectory adjustment mechanism drives a first rotating disk to rotate, which in turn drives a guide slider to revolve. The guide slider then drives a stirring shaft to revolve, which in turn drives stirring blades to revolve. This revolve movement of the stirring shaft and blades stirs the raw materials. Simultaneously, the motion trajectory adjustment mechanism changes the radius of the stirring shaft's revolution, thereby altering the motion trajectory of the stirring shaft and blades. This causes the stirring shaft and blades to move in the opposite direction to the center of the reaction vessel or the side wall during their revolution, allowing them to stir any part of the reaction vessel. This avoids the problem of uneven material distribution when the stirring shaft and blades only stir at the center of the reaction vessel. The rotating component drives the stirring shaft to rotate by changing its radius of revolution, which in turn drives the stirring blades to rotate, thus improving the stirring effect of the stirring shaft and blades.
