Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel equipment, specifically a chemical batching reaction vessel that facilitates mixing. Background Technology

[0002] Reactors are crucial core equipment in the chemical industry. Their typical workflow involves adding various chemical raw materials into a sealed reactor container and controlling process parameters such as temperature, pressure, and stirring rate to induce a predetermined chemical reaction in a specific environment. This equipment, with its precise control over the reaction process, enables effective collisions and recombination between raw material molecules, ultimately producing the target reaction product efficiently. It is widely used in numerous industrial production scenarios, including petrochemicals, pharmaceuticals, and polymer synthesis.

[0003] Existing reactors mostly rely on a single rotary stirring mode during material mixing. This unidirectional stirring mechanism leads to a series of process defects: First, the uniform fluid flow pattern easily creates eddy currents, resulting in limited material mixing dimensions and insufficient microscopic dispersion uniformity. Second, the generation of eddies exacerbates the thickening of the heat transfer boundary layer, causing a gradient distribution of the temperature field within the reactor, especially in exothermic or endothermic reactions, where local overheating or undercooling is prominent. Furthermore, traditional stirring methods easily create flow blind zones in areas such as reactor corners and near the stirring shaft, where materials remain abnormally long, leading to localized over- or incomplete reactions. Ultimately, this results in large product quality dispersion, poor batch-to-batch consistency, and difficulty meeting the yield requirements of high-end chemical products. This inefficiency in mixing and heat transfer is particularly pronounced in fields with stringent uniformity requirements, such as fine chemicals and catalyst preparation. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a chemical batching reactor that facilitates mixing, thus solving the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chemical batching reactor for convenient mixing, comprising a reactor body, a motor mounted on the top of the reactor body, an A bevel gear coaxially fixedly connected to the output end of the motor through the reactor body, an A rotating shaft coaxially fixedly connected to the A bevel gear, a B bevel gear rotatably connected to the A rotating shaft, a B sleeve shaft fixedly connected to the lower end of the B bevel gear, the B sleeve shaft being sleeved outside the A rotating shaft, an A stirring blade fixedly connected to the A rotating shaft, and a B stirring blade fixedly connected to the lower end of the B sleeve shaft;

[0006] A disc is fixedly connected to the upper end of the B-set shaft. Two gears are rotatably connected to the disc. Spiral blades are fixedly connected to the lower ends of the two gears.

[0007] As a further embodiment of this utility model: a C-bevel gear is rotatably connected inside the reactor body.

[0008] As a further embodiment of this utility model: the C bevel gear meshes with both the A bevel gear and the B bevel gear.

[0009] As a further embodiment of this utility model: the internal gear ring meshes with both gears.

[0011] As a further embodiment of this utility model: a slide rail is provided on the bottom side wall of the reactor body, and the scraper is slidably connected to the slide rail.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. Through the combined transmission of bevel gears A, B and C, the reverse rotation of shaft A and shaft B is achieved, which makes the stirring blades A and B form a convective shear force field, breaking the flow limitation of traditional unidirectional stirring and greatly improving the turbulence and micro-uniformity of material mixing.

[0014] 2.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figures 1-4 As shown, this utility model provides a technical solution:

[0022] A chemical batching reactor for easy mixing includes a reactor body 1. A motor 2 is installed on the top of the reactor body 1. The output end of the motor 2 passes through the reactor body 1 and is coaxially fixedly connected to a bevel gear A 3. A rotating shaft A 4 is coaxially fixedly connected to the bevel gear A 4. A bevel gear B 5 is rotatably connected to the rotating shaft A 4. A sleeve shaft B 6 is fixedly connected to the lower end of the bevel gear B 5. The sleeve shaft B 6 is sleeved outside the rotating shaft A 4. An agitator blade A 7 is fixedly connected to the rotating shaft A 4. An agitator blade B 8 is fixedly connected to the lower end of the sleeve shaft B 6.

[0023] A disc 9 is fixedly connected to the upper end of shaft 6. Two gears 10 are rotatably connected to the disc 9. Spiral blades 11 are fixedly connected to the lower ends of the two gears 10. A scraper 12 is rotatably connected to the lower end of the spiral blades 11. An internal gear ring 13 is provided inside the reactor body 1. An inlet is provided on the reactor body 1. An inlet hopper 14 is connected to the inlet. An outlet is provided at the bottom of the reactor body 1. An outlet pipe 15 is connected to the outlet. A base 16 is fixedly connected to the bottom of the reactor body 1.

[0024] As a further embodiment of this utility model: a C-bevel gear 17 is rotatably connected inside the reactor body 1;

[0025] Specifically, solid powder and liquid raw materials are fed into the reactor body 1 according to the formula ratio through the feed hopper 14. The motor 2 is started to drive the A bevel gear 3 to rotate. Through the transmission of the C bevel gear 17, the A rotating shaft 4 and the B sleeve shaft 6 are synchronously rotated in opposite directions. Through the opposite rotation of the A stirring blade 7 and the B stirring blade 8, the material is evenly dispersed from the central area into the reactor body 1. Then, the rotation of the B bevel gear 5 drives the disk 9 to rotate. The disk 9 drives the gear 10 to roll along the inner tooth ring 13, so that the spiral blade 11 achieves a "revolution + rotation" compound motion, thereby realizing a compound flow field of radial shearing and axial circulation of the material inside the reactor body 1, thereby achieving a thorough mixing effect. The base 16 adopts a four-leg support structure, which effectively disperses the vibration and torque generated by the reactor body 1 during operation. Even under high-speed stirring conditions, it avoids stirring imbalance caused by shaking, significantly improving the safety and reliability of equipment operation.

[0026] A C-bevel gear 17 is rotatably connected inside the reactor body 1. The C-bevel gear 17 meshes with both the A-bevel gear 3 and the B-bevel gear 5. The internal gear ring 13 meshes with both gears 10. The scraper 12 is attached to the inner wall of the reactor body 1. A slide is provided on the bottom side wall of the reactor body 1, and the scraper 12 is slidably connected to the slide.

[0027] Specifically, the scraper 12 moves synchronously with the spiral blade 11 to break the boundary layer, allowing the material in the near-wall area to participate in the main circulation. After the material has completed the reaction and mixing, the discharge pipe 15 valve is opened, and the motor 2 is driven in the reverse direction. The axial thrust of the spiral blade 11 presses the material toward the discharge port. The arc-shaped design at the bottom of the scraper 12 works in conjunction with the slide to remove residual material at the bottom of the vessel and reduce the discharge residue rate.

[0028] The working principle of this utility model is as follows:

[0029] First, solid powder and liquid raw materials are fed into the reactor body 1 according to the formula ratio through the feed hopper 14;

[0030] Secondly, the motor 2 is started to drive the A bevel gear 3 to rotate. Through the transmission of the C bevel gear 17, the A rotating shaft 4 and the B sleeve shaft 6 are synchronously rotated in opposite directions. Through the opposite rotation of the A stirring blade 7 and the B stirring blade 8, the material is evenly dispersed from the central area into the reactor body 1.

[0031] Next, the rotation of the B bevel gear 5 drives the disk 9 to rotate, and the disk 9 drives the gear 10 to roll along the internal gear ring 13, so that the spiral blade 11 achieves a "revolution + rotation" compound motion, thereby realizing a compound flow field of radial shearing and axial circulation of the material inside the reactor body 1, thus achieving a thorough mixing effect. The base 16 adopts a four-leg support structure, which effectively disperses the vibration and torque generated during the operation of the reactor body 1. Even under high-speed stirring conditions, it avoids stirring imbalance caused by shaking, significantly improving the safety and reliability of equipment operation. The scraper 12 moves synchronously with the spiral blade 11, breaking the boundary layer and allowing the material in the near-wall area to participate in the main circulation.

[0032] Finally, after the materials have completed the reaction and mixing, the valve of the discharge pipe 15 is opened, and the reverse drive motor 2 is activated. The axial thrust of the spiral blade 11 presses the materials toward the discharge port. The arc-shaped design of the bottom of the scraper 12, in conjunction with the slide, removes the residual materials at the bottom of the vessel and reduces the discharge residue rate.

[0033] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
