Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to a device for quickly heating epoxidized soybean oil. Background Art

[0002] Epoxidized soybean oil is an important chemical raw material. In polyvinyl chloride products, epoxy soybean oil is often used as a plasticizer and stabilizer. It can improve the flexibility, wear resistance and weather resistance of polyvinyl chloride products, while reducing the volatility and migration of products during processing and use. In addition, epoxy soybean oil can also be used in coatings, adhesives, inks, synthetic rubber and other fields to improve the performance of these products.

[0003] In the production process of epoxidized soybean oil, the control of reaction temperature has a significant impact on product quality and production efficiency. However, the existing production equipment is prone to local overheating during the rapid heating process, resulting in uneven heating of the raw materials and unstable product quality. Therefore, an epoxidized soybean oil rapid heating device is urgently needed to solve the above problems. Utility Model Content

[0008] Preferably, a sealed inner wall is fixedly connected to the inner side of the top of the electric heating reactor, and a sealing rubber ring is provided on the outer side of the sealed inner wall.

[0009] Preferably, a second lug is symmetrically fixedly connected to the outer side of the top of the electric heating reactor, and a limited position insertion hole is provided through the second lug.

[0012] Preferably, the limiting rod is slidably inserted into the limiting hole.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The utility model uses the strong shear force and turbulence generated by the mirror-image stirring of the first turbine agitator and the second turbine agitator to effectively break up the particles or droplets in the material, increase the surface area, and thus improve the heat transfer and mass transfer rates. This design enables the raw materials to be quickly and evenly mixed in a short time. Since the rotation of the first turbine agitator and the second turbine agitator stirs the raw materials in a circulating flow, the heat transfer is accelerated.

DETAILED DESCRIPTION

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5 The utility model provides an embodiment: a rapid heating device for epoxidized soybean oil, comprising an electric heating reactor 1, a fixed bracket 2, a stirring top cover 3 and a motor 4. The inner side of the top end of the fixed bracket 2 is fixedly connected to the middle part of the outer side of the electric heating reactor 1, the stirring top cover 3 is pressed on the top end of the electric heating reactor 1, and the motor 4 is fixedly installed at the middle part of the top end of the stirring top cover 3. The driving end of the motor 4 is fixedly installed with a stirring shaft 12, and the top end of the stirring shaft 12 is rotatably connected to the middle part of the stirring top cover 3 through a rotating shaft. The driving end of the motor 4 drives the stirring shaft 12 to rotate clockwise, indirectly driving the first turbine stirring paddle 13 and the second turbine stirring paddle 14 to rotate clockwise.

[0023] A first turbine stirring paddle 13 is fixedly connected to the middle of the stirring shaft 12, and a second turbine stirring paddle 14 is fixedly connected to the bottom end of the stirring shaft 12. The turbine blades inside the first turbine stirring paddle 13 and the second turbine stirring paddle 14 are mirror-imaged. The rotation of the first turbine stirring paddle 13 pushes the raw materials at the bottom of the electric heating reactor 1 upward, and the clockwise rotation of the second turbine stirring paddle 14 pushes the raw materials above the second turbine stirring paddle 14 downward. At this time, the raw materials between the first turbine stirring paddle 13 and the second turbine stirring paddle 14 diffuse to the surroundings, thereby stirring the raw materials to circulate and accelerate heat transfer.

[0024] The outer side of the stirring top cover 3 is symmetrically fixedly connected with a first support ear 6, the bottom end of the first support ear 6 is fixedly connected with a limiting rod 7, and the outer side of the top of the electric heating reactor 1 is symmetrically fixedly connected with a second support ear 8, and a limiting hole 9 is penetrated through the second support ear 8, and the limiting rod 7 is slidably inserted into the inside of the limiting hole 9. The stirring top cover 3 and the electric heating reactor 1 are limited and fixed by inserting the limiting rod 7 into the limiting hole 9 to prevent the rotation of the motor 4 from driving the stirring top cover 3 to rotate.

[0025] A sealed inner wall 5 is fixedly connected to the inner side of the top of the electric heating reactor 1, and a sealing rubber ring is provided on the outer side of the sealing inner wall 5. When the stirring top cover 3 is covered on the top of the electric heating reactor 1, the inner side wall of the bottom end of the stirring top cover 3 is sealed between the sealing rubber ring and the sealing inner wall 5 to prevent heat dissipation and overflow of internal raw materials.

[0026] The top of the stirring cover 3 is symmetrically fixedly connected with a pull ring 10, and the stirring cover 3 is provided with a groove directly below the pull ring 10. The staff applies external force on the pull ring 10 to cover the stirring cover 3 on the top of the electric heating reactor or lift the stirring cover 3.

[0027] The bottom end of the stirring cover 3 is fixedly connected with a disruptor plate 11, which can change the flow path of the raw materials, reduce the formation of vortices and dead zones, avoid local uneven mixing or non-stirring, and thus improve the stirring effect and mixing quality.

[0028] Working principle: During use, first fix the fixing bracket 2 to the ground or other working area by bolts, and then pour the raw materials into the electric heating reactor 1 by external force, and then use external force to pull up the stirring cover 3 through the pull ring 10 and cover the top of the electric heating reactor 1, and the limiting plug rod 7 slides into the inside of the limiting plug hole 9 to limit and fix the stirring cover 3. When the electric heating reactor 1 is started for rapid heating, the motor 4 is started, and the driving end of the motor 4 drives the stirring shaft 12 to rotate clockwise. The rotation of the stirring shaft 12 drives the first turbine stirring paddle 13 and the second turbine stirring paddle 14 to rotate respectively. When the first turbine stirring paddle 13 rotates clockwise, the turbine blades inside the first turbine stirring paddle 13 push the raw materials to rotate and move upward. At this time, negative pressure is formed inside the first turbine stirring paddle 13, and the raw materials below the first turbine stirring paddle 13 move upward under the action of pressure and enter the first turbine stirring paddle 1 3, so that the rotation of the first turbine stirring paddle 13 pushes the raw materials at the bottom of the electric heating reactor 1 upward, and the clockwise rotation of the second turbine stirring paddle 14 pushes the raw materials above the second turbine stirring paddle 14 downward. During the stirring process, the strong shear force and turbulence generated by the mirror stirring of the first turbine stirring paddle 13 and the second turbine stirring paddle 14 help to break the particles or droplets in the material, increase the surface area, and thus improve the heat transfer and mass transfer rates. At this time, the raw materials between the first turbine stirring paddle 13 and the second turbine stirring paddle 14 diffuse to the surroundings, thereby stirring the raw materials to circulate and accelerate heat transfer. Since the first turbine stirring paddle 13 and the second turbine stirring paddle 14 will form a vortex when they rotate, when the vortex encounters the obstruction of the disruptor 11, it can change the flow path of the raw materials, reduce the formation of vortices and dead zones, and thus improve the stirring effect and mixing quality.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
