Description

Technical Field

[0001] This utility model belongs to the field of homogenizing reaction vessel technology, and particularly relates to tall oleic acid homogenizing reaction vessel. Background Technology

[0002] In the field of bio-based chemical product manufacturing, tall oleic acid is an important industrial raw material, and the homogenization effect of its treatment directly affects the efficiency of subsequent esterification reactions and the performance of end products. The radial single-layer reverse stirring structure currently used in the industry is essentially derived from the design concept of general-purpose reactors in the last century. However, it has gradually revealed its structural incompatibility when dealing with high-viscosity, heat-sensitive oleic acid systems.

[0003] From a fluid dynamics perspective, the core problem with traditional structures lies in the three-dimensional discontinuity of the flow field they create. Practical monitoring shows that when processing tall oleic acid with a viscosity exceeding 800 cP, a significant velocity gradient discontinuity occurs in the axial direction of the tank, with a flow velocity decrease of up to 62% at a distance of 0.7R (where R is the tank radius) from the stirring shaft, directly leading to stratification of the reactants.

[0004] Existing technologies attempt to improve mixing by adding impellers, but such improvements often fall into a vicious cycle of "increased structural complexity - increased maintenance costs." Production data from a large oil company shows that while the use of a dual-impeller reactor improved mixing uniformity by 15%, the equipment failure rate increased by 40% year-on-year, severely restricting production flexibility. Utility Model Content

[0005] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0006] The tall oleic acid homogenizing reactor includes:

[0007] Tank body;

[0008] The stirring mechanism includes a rotating shaft with spiral blades installed at the bottom end of the shaft. A centrifuge cylinder with its opening facing downwards is fixedly connected to the middle of the rotating shaft. Centrifuge holes larger than the particle size of the material are opened on the outer ring wall of the centrifuge cylinder, and radial blades are arranged around the periphery of the centrifuge cylinder.

[0009] During homogenization, the material at the bottom of the tank is conveyed upward to the inner cavity of the centrifuge tube through the spiral blades. After being centrifuged by the centrifuge tube, the material is thrown outward from the centrifuge hole. The material thrown outward is radially stirred by the radial blades and then flows back to the bottom of the tank, thereby forming a two-way mixing in both the radial and axial directions.

[0010] As a preferred embodiment of the above technical solution, the bottom of the tank is provided with support legs, and the top of the tank is equipped with a tank cover.

[0011] As a preferred embodiment of the above technical solution, the stirring mechanism further includes a motor, with the top end of the rotating shaft fixed to the output shaft of the motor;

[0012] A motor mounting bracket is fixedly connected to the top center of the can lid, and the motor is mounted on the top of the motor mounting bracket.

[0013] As a preferred embodiment of the above technical solution, a first mounting sleeve is detachably installed on the bottom periphery of the rotating shaft, and the spiral blade is fixedly installed on the periphery of the first mounting sleeve.

[0014] As a preferred embodiment of the above technical solution, a second mounting sleeve is detachably installed in the middle of the rotating shaft, and the centrifuge cylinder and radial blades are fixedly installed on the periphery of the second mounting sleeve.

[0015] As a preferred embodiment of the above technical solution, the cross-section of the radial blade is "C" shaped, and the centrifuge cylinder is located within the "C" shaped notch of the radial blade.

[0016] The beneficial effects of this utility model are as follows:

[0017] The tall oleic acid homogenizing reactor provided by this invention achieves bidirectional mixing of materials in both radial and axial directions through a carefully designed stirring mechanism. Compared with traditional structures, this reactor not only significantly improves mixing uniformity but also effectively avoids material stratification. This innovative design ensures the efficient execution of subsequent esterification reactions, thereby improving the performance and quality of the final product.

[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0023] Example

[0024] like Figures 1-3 As shown, the tall oleic acid homogenizing reaction vessel of this invention mainly includes a vessel body 10, which serves as the main part of the reaction and is designed with sufficient volume to accommodate reactants such as tall oleic acid. The shape and size of the vessel body are optimized according to production needs to ensure effective flow and mixing of materials within the vessel. Support legs 11 are provided at the bottom of the vessel body 10, which not only provide stable support but also ensure the balance and stability of the reaction vessel during operation. A lid 12 is installed at the top of the vessel body 10. The lid is designed for sealing, effectively preventing splashing of materials during stirring and the entry of external impurities.

[0025] The stirring mechanism is the core component of this invention. It includes a motor 31, a rotating shaft 32, a first mounting sleeve 33, spiral blades 34, a second mounting sleeve 37, a centrifuge cylinder 35, and radial blades 36. The motor 31 is mounted on a motor mounting bracket 20 on the top of the tank cover 12, providing power to the entire stirring mechanism. The rotating shaft 32, as the power transmission component, has its top end tightly connected to the output shaft of the motor.

[0026] A first mounting sleeve 33 is detachably installed on the outer periphery of the bottom end of the rotating shaft 32, and the spiral blade 34 is fixedly installed on the outer periphery of the first mounting sleeve 33. The spiral blade is designed with material conveying efficiency in mind, and it can effectively convey the material at the bottom of the tank 10 upward to the inner cavity of the centrifuge cylinder 35.

[0027] A second mounting sleeve 37 is also detachably installed in the middle of the rotating shaft 32, and the centrifuge cylinder 35 and radial blades 36 are fixedly installed on the outer periphery of the second mounting sleeve 37. The centrifuge cylinder 35 has a unique design with its opening facing downwards and centrifugal holes 351 larger than the particle size of the material on its outer ring wall. When the material is conveyed into the inner cavity of the centrifuge cylinder, it will be subjected to centrifugal force and thrown outwards from the centrifugal holes 351.

[0028] The radial blades 36 are designed to facilitate radial mixing of the material. Their cross-section is C-shaped, and the centrifuge cylinder 35 is located within the C-shaped recess of the radial blades. Thus, when the material is ejected from the centrifuge cylinder, it is agitated by the radial blades and flows back to the bottom of the tank 10, resulting in both radial and axial mixing.

[0029] In practical applications, when motor 31 starts, it drives shaft 32 to rotate. Spiral blades 34 begin to convey material from the bottom of tank 10 upwards. After entering the inner cavity of centrifuge cylinder 35, the material is subjected to centrifugal force and thrown outwards through centrifugal orifice 351. The thrown material is then evenly dispersed and returned to the bottom of the tank by the radial stirring action of radial blades 36. This process is repeated continuously, forming a two-way mixing process in both radial and axial directions, thereby achieving effective homogenization of high-viscosity, heat-sensitive oleic acid systems.

[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
