Description

Technical Field

[0001] This utility model relates to the field of zirconium oxide precursor production technology, specifically a reaction vessel for synthesizing zirconium oxide precursors. Background Technology

[0002] Zirconia precursors are intermediate compounds or solutions used to prepare zirconia materials (such as ceramics, thin films, and composite materials), which ultimately form zirconia through chemical transformation (such as hydrolysis, calcination, and pyrolysis). Reactors used for synthesizing zirconia precursors are specialized chemical reaction vessels. These mainly include high-efficiency stirred reactors, automated control reactors, integrated concentration and filtration reactors, hydrothermal / high-pressure reactors, and dedicated co-precipitation reactors.

[0003] In high-efficiency stirred reactors, due to the large size of the vessel and the need for high-speed rotation of the stirring rod, a support rod is added inside the vessel at the middle of the stirring rod. The middle of the stirring rod is inserted into the middle of the support rod without affecting the rotation of the stirring rod. This support rod supports the stirring rod to prevent bending due to prolonged high-speed rotation. However, the existing method of installing the support rod requires first fixing the support rod inside the vessel, then fitting one of the stirring blades onto the stirring rod, inserting the stirring rod into the middle of the support rod, and then attaching the upper and lower stirring blades through the observation hole. Later replacement of the stirring rod or stirring blades requires disassembling all these components sequentially before removing the top cover, which is quite cumbersome. Therefore, a reactor for synthesizing zirconia precursors is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a reaction vessel for synthesizing zirconia precursors, thereby solving the problems mentioned in the background section. To solve these technical problems, this invention is achieved through the following technical solution:

[0005] This utility model relates to a reaction vessel for synthesizing zirconium oxide precursors, comprising:

[0006] A reaction vessel, comprising a tank body and a top cover, wherein the top cover is fixed to the top of the tank body by bolts;

[0007] The support assembly includes a first fixed plate, a connecting shaft, a spring column, an arc-shaped plate, a second fixed plate, a limiting hole, and a movable rod. The first fixed plate is fixed inside the tank, the connecting shaft is fixed between the two first fixed plates, one end of the spring column is rotatably connected to the connecting shaft, the middle of the outer side of the arc-shaped plate is fixed to the other end of the spring column, the second fixed plate is fixed inside the tank and located at the upper end of the first fixed plate, the limiting hole is opened in the middle of the second fixed plate, the movable rod is inserted into the limiting hole, and the lower end of the movable rod is located above the other end of the spring column away from the arc-shaped plate.

[0008] Furthermore, the support assembly also includes ball bearings, which are rotatably connected to the inner side of the arc-shaped plate.

[0009] Furthermore, the support assembly also includes a first limiting plate and a circular spring. The first limiting plate is fixed to the top of the movable rod, and the circular spring is sleeved on the upper end of the movable rod, with one end fixed to the side of the first limiting plate and the other end fixed to the side of the upper second fixing plate.

[0010] Furthermore, the reactor also includes a stirring rod and a feeding pipe. The stirring rod is rotatably connected to the middle of the lower end of the top cover, and the feeding pipe is fixed on the top cover, with its lower end inserted into the tank body.

[0011] Furthermore, there are two arc-shaped plates, symmetrically distributed inside the tank, and the ball bearings on the arc-shaped plates are movably connected to the stirring rod, and the first limiting plate is movably connected to the lower end of the top cover.

[0012] Furthermore, it also includes a connecting assembly, which includes a fixing strip, a slot, an insert block, and a second limiting plate. The fixing strip is fixed inside the tank, the slot is opened in the middle of the side of the fixing strip, the insert block is inserted into the slot, and the first fixing plate and the second fixing plate are fixed to the side of the insert block. The second limiting plate is fixed to the top of the insert block and is fixed to the top of the fixing strip by screws.

[0013] Furthermore, the connecting assembly also includes a pull ring, which is fixed to the middle of the upper end of the second limiting plate.

[0014] This utility model has the following beneficial effects:

[0015] This invention, through its supporting assembly, allows for easy access to the top cover during maintenance. The first limiting plate disengages from the top cover's pressure, causing a spring to extend and move the first limiting plate upwards. This, in turn, moves the movable rod upwards along the limiting hole in the second fixed plate. The lower end of the movable rod moves upwards, causing the spring column to rotate around the connecting shaft on the first fixed plate. The arc-shaped plate falls downwards, detaching from the stirring rod. The end of the spring column with the arc-shaped plate is pressed against the stirring rod, compressing the spring column until the arc-shaped plate is completely detached from the stirring rod. After maintenance, the top cover is placed on the tank, the first limiting plate is pressed down, and the lower end of the movable rod pushes the spring column downwards, while the other end of the spring column is lifted until the ball bearings on the arc-shaped plate adhere to the stirring rod. This design facilitates opening the top cover for later maintenance without disassembling the supporting assembly. Attached Figure Description

[0028] The support assembly includes a first fixed plate 20, a connecting shaft 21, a spring column 22, an arc-shaped plate 23, a second fixed plate 25, a limiting hole 26, and a movable rod 27. The first fixed plate 20 is fixed inside the tank body 10, the connecting shaft 21 is fixed between the two first fixed plates 20, one end of the spring column 22 is rotatably connected to the connecting shaft 21, the middle of the outer side of the arc-shaped plate 23 is fixed to the other end of the spring column 22, the second fixed plate 25 is fixed inside the tank body 10 and is located at the upper end of the first fixed plate 20, the limiting hole 26 is opened in the middle of the second fixed plate 25, and the movable rod 27 is inserted into the limiting hole 26, with the lower end of the movable rod 27 located above the other end of the spring column 22 away from the arc-shaped plate 23.

[0029] The support assembly also includes ball bearings 24, which are rotatably connected to the inside of the arc-shaped plate 23;

[0030] The support assembly also includes a first limiting plate 28 and a coil spring 29. The first limiting plate 28 is fixed to the top of the movable rod 27, and the coil spring 29 is sleeved on the upper end of the movable rod 27, with one end fixed to the side of the first limiting plate 28 and the other end fixed to the side of the upper second fixing plate 25.
