Description

Technical Field

[0001] This utility model relates to the field of stirring device technology, and in particular to a stirring device for an emulsion reaction vessel. Background Technology

[0002] An emulsion reaction vessel is a device used to prepare emulsions. It is widely used in industries such as paint making, coatings, pharmaceuticals, chemicals, machining, and automotive parts processing. Its main function is to combine two or more immiscible liquids into a stable emulsion through emulsifiers and mechanical action.

[0003] In an emulsion reactor, emulsifiers are added to the oil and aqueous phases and stirred until the emulsifiers are uniformly dispersed, achieving effective mixing of the oil and aqueous phases and forming a stable emulsion system. Stirred reactors typically have only one stirring shaft, which only drives the stirring rod to rotate. This results in low mixing efficiency of the solution and solute, especially in the inefficient zone near the inner wall of the reactor, leading to poor mixing in these areas and incomplete mixing of the solution. Low stirring efficiency also means that some materials cannot be fully mixed, resulting in uneven mixing of the oil phase and other components in the emulsion, severely affecting the emulsion's performance. During mixing in the reactor, the oil phase or insufficiently stirred products adhere to the reactor wall, causing uneven material distribution and further reducing stirring efficiency, thus lowering the emulsion's quality.

[0004] Therefore, the applicant provides a stirring device for an emulsion reaction vessel to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a stirring device for an emulsion reaction vessel, which solves the problems of uneven mixing of emulsions, resulting in reduced emulsion performance and low stirring efficiency in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides an emulsion reaction vessel stirring device, including a vessel body, a drive motor installed on the top of the vessel body, the output shaft of the drive motor connected to a connecting frame, a stirring component installed at the center of the connecting frame, and rotating components installed on both sides of the stirring component. The rotating components abut against the side wall of the vessel body and are used to scrape the material on the inner side wall of the vessel body and to stir the material in the area near the inner side wall.

[0007] A further improvement of the present invention is that the connecting frame includes a vertically downward mounting rod and a horizontal fixing rod, a stirring assembly is provided on the mounting rod, and a rotating assembly is connected to both ends of the fixing rod.

[0008] A further improvement of the present invention is that the stirring assembly includes a first stirring wheel, a second stirring wheel, and a third stirring wheel arranged sequentially from top to bottom on the mounting rod.

[0009] A further improvement of the present invention is that the first stirring wheel and the third stirring wheel have the same shape, the diameter of the third stirring wheel is larger than the diameter of the first stirring wheel, and the diameter of the second stirring wheel is larger than the diameter of the third stirring wheel.

[0010] A further improvement of the present invention is that the first stirring wheel includes a bushing fitted onto the mounting rod. Two sets of blades are evenly arranged on the outer circumference of the bushing. The two sets of blades are symmetrical in pairs and staggered vertically. The blades are similar to triangles. One corner of the blade is fixed to the bushing, and the opposite side of one corner of the blade is an arc.

[0011] A further improvement of the present invention is that the second stirring wheel includes a bushing, a fixing strip is provided on the bushing, and a spiral blade is provided on the fixing strip.

[0012] A further improvement of the present invention is that the rotating assembly includes a rotating shaft, the end of which is adapted to be fitted onto the end of a fixed rod, and two fixed rings are spaced apart on the rotating shaft. The two fixed rings abut against the top and bottom surfaces of the fixed rod respectively, and are used to limit the vertical movement of the rotating shaft on the fixed rod.

[0013] A further improvement of this utility model is that at least two scrapers are provided on the outer periphery of the rotating shaft, with the outer edge of the scrapers contacting the inner wall of the vessel to scrape the material on the inner wall of the vessel.

[0014] A further improvement of this utility model is that the connecting frame also includes a reinforcing rod, which is fixed on the mounting rod and spaced below the fixed rod. The rotating shaft is adapted to pass through both ends of the reinforcing rod and is used to limit the rotation of the rotating shaft.

[0015] A further improvement of this utility model is that a feed inlet is provided at the top of the vessel and a discharge outlet is provided at the bottom.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. This utility model provides an emulsion reaction vessel stirring device. The stirring device uses a drive motor to drive the stirring components to mix different components in the emulsion in the reaction vessel, forming a uniform dispersion system. The rotating components fully mix the area near the inner wall of the stirring vessel and scrape off the oil phase or insufficiently stirred product adhering to the reaction vessel wall, so that the emulsion in the reaction vessel is fully mixed, improving stirring efficiency and improving the performance and quality of the emulsion.

[0018] 2. This utility model provides a stirring device for an emulsion reaction vessel. The stirring shaft in the stirring assembly of this device drives a first stirring wheel, a second stirring wheel, and a third stirring wheel arranged sequentially from top to bottom to rotate, mixing different components in the emulsion in the reaction vessel to form a uniform dispersion system. The first stirring wheel is located in the lower elliptical position of the stirring vessel and is the smallest diameter stirring wheel, which fully stirs the lower part of the stirring vessel, reduces dead corners at the bottom during stirring, and improves the mixing effect. The second stirring wheel is located in the middle and lower part of the stirring vessel. The second stirring wheel has a spiral blade, and its spiral structure can adapt to emulsions of various viscosities and fluidities. The second stirring wheel is the largest diameter stirring wheel, which can provide strong mixing ability, forming eddies and turbulence, thereby achieving a better stirring effect. The third stirring wheel is located at the top and stirs the upper emulsion. The three stirring wheels work together to fully stir the upper, middle, and lower parts of the stirring vessel, which can more evenly distribute the stirring force and ensure that the materials are fully mixed in the container, thereby improving the stirring effect.

[0019] 3. This utility model provides an emulsion reaction vessel stirring device. In this stirring device, the scraper in the rotating component contacts the side wall of the vessel. The scraper scrapes and adheres to the oil phase or insufficiently stirred product on the side wall of the vessel, so as to make the material evenly distributed and the emulsion fully mixed, thereby improving the stirring efficiency. The drive motor drives the fixed rod in the connecting frame to rotate. The fixed rod drives the rotating shaft fitted at the end of the fixed rod to rotate inside the reaction vessel. Under the pushing force of the scraper on the side wall of the vessel and the flow of the emulsion, the rotating shaft rotates inside the fixed rod, stirring the emulsion near the side wall of the stirring vessel, so as to make the emulsion material fully mixed, and improve the performance of the emulsion and the stirring efficiency.

[0020] 4. The present invention provides a stirring device for an emulsion reaction vessel. In this stirring device, the fixing ring in the rotating assembly is used to limit the vertical movement of the rotating shaft on the fixing rod, so that the rotating shaft rotates stably within the fixing rod. The reinforcing rod limits the vertical movement of the rotating shaft, thereby improving the stability of the rotating assembly when it rotates within the fixing rod and increasing the stirring efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The present invention will be further explained below with reference to specific embodiments.

[0032] like Figure 1-5 As shown in the figure, this embodiment provides an emulsion reaction vessel stirring device, including a vessel body 1. A feed inlet 6 is provided at the top of the vessel body 1 to ensure that materials enter the interior of the reaction vessel; a discharge outlet 7 is provided at the bottom for collecting and discharging the emulsion after uniform mixing. A drive motor 2 is provided at the top of the vessel body 1, and the output shaft of the drive motor 2 is connected to a connecting frame 3. A stirring component 4 is installed at the center of the connecting frame 3. Rotating components 5 are respectively provided on both sides of the stirring component 4. The rotating components 5 abut against the side wall of the vessel body 1, used to scrape the material on the inner side wall of the vessel body 1 and to stir the material near the inner side wall. The drive motor drives the stirring component to mix the different components in the emulsion in the reaction vessel, forming a uniform dispersion system. The rotating components thoroughly mix the area near the inner side wall of the vessel and scrape off the oil phase or insufficiently stirred product adhering to the reaction vessel wall, ensuring that the emulsion in the reaction vessel is fully mixed, improving stirring efficiency, and improving the performance and quality of the emulsion.

[0033] like Figures 2-4 As shown, in this embodiment, the connecting frame 3 includes a vertically downward mounting rod 31 and a horizontal fixing rod 32. A stirring assembly 4 is provided on the mounting rod 31, and a rotating assembly 5 is connected to both ends of the fixing rod 32. The stirring assembly 4 includes a first stirring wheel 41, a second stirring wheel 42, and a third stirring wheel 43 arranged sequentially from top to bottom on the mounting rod 31. The first stirring wheel 41 and the third stirring wheel 43 have the same shape, the diameter of the third stirring wheel 43 is larger than the diameter of the first stirring wheel 41, and the diameter of the second stirring wheel 42 is larger than the diameter of the third stirring wheel 43. The stirring assembly of this stirring device uses a stirring shaft to drive a first stirring wheel, a second stirring wheel, and a third stirring wheel arranged sequentially from top to bottom to rotate. This mixes the different components in the emulsion within the reaction vessel, forming a uniform dispersion system. The first stirring wheel, located in an elliptical position at the bottom of the vessel, is the smallest in diameter and thoroughly stirs the lower part of the vessel, reducing dead zones and improving mixing efficiency. The second stirring wheel, located in the lower middle part of the vessel, has helical blades. Its helical structure can adapt to emulsions of various viscosities and fluidities. As the largest in diameter, the second stirring wheel provides strong mixing power, creating eddies and turbulence for even better stirring results. The third stirring wheel, located at the top, stirs the upper emulsion. The combined action of these three stirring wheels thoroughly stirs the upper, middle, and lower parts of the vessel, distributing the stirring force more evenly and ensuring thorough mixing of the materials within the container, thereby improving the stirring effect.

[0034] like Figure 3As shown, the first stirring wheel 41 includes a bushing 33 fitted onto the mounting rod 31. The bushing 33 fixes the first stirring wheel 41 onto the mounting rod 31. Two sets of blades 412 are evenly arranged on the outer circumference of the bushing 33. The two sets of blades 412 are symmetrically arranged in pairs and staggered vertically. The blades 412 are similar to triangles, with one corner of each blade fixed to the bushing 33 and the opposite side of the corner being an arc. The staggered blades can generate an asymmetric flow field structure, effectively eliminating the mixing isolation zone and inducing overall chaotic flow of the fluid, thereby improving mixing efficiency. The triangular blades generate shear force through rotation, which can effectively disperse immiscible liquids into tiny droplets, thereby promoting the emulsification process and improving emulsification efficiency.

[0035] like Figure 4 As shown, the second stirring wheel 42 includes a bushing 33, which fixes the second stirring wheel 42 to the mounting rod 31. A fixing strip 421 is provided on the bushing 33, and a spiral blade 422 is provided on the fixing strip 421. The spiral blade, with its spiral structure, can adapt to emulsions of various viscosities and fluidities. The second stirring wheel is the largest diameter stirring wheel, which can provide strong mixing capacity, forming eddies and turbulence, thereby achieving better mixing effect.

[0036] like Figure 5 As shown, the rotating assembly 5 includes a rotating shaft 51, the end of which is fitted to the end of a fixed rod 32. Two fixing rings 52 are spaced apart on the rotating shaft 51, and the two fixing rings 52 abut against the top and bottom surfaces of the fixed rod 32 respectively, for limiting the vertical movement of the rotating shaft 51 when it rotates on the fixed rod 32, so that the rotating shaft 51 rotates stably within the fixed rod 32. At least two scrapers 53 are provided on the outer periphery of the rotating shaft 51, and the outer edges of the scrapers 53 contact the inner wall of the vessel body 1 for scraping the material on the inner wall of the vessel body 1. The scraper in the rotating assembly contacts the side wall of the reactor body, scraping away the oil phase or insufficiently stirred products adhering to the side wall, thus ensuring uniform material distribution and thorough mixing of the emulsion, improving stirring efficiency. The drive motor drives the fixed rod in the connecting frame to rotate, and the fixed rod drives the rotating shaft fitted at the end of the fixed rod to rotate inside the reactor with the output end of the drive motor as the axis. Under the pushing force of the scraper against the inner side wall of the reactor body and the flow of the emulsion, the rotating shaft rotates within the fixed rod, stirring the emulsion near the inner side wall of the reactor body, ensuring thorough mixing of the emulsion materials, uniform stirring, and improving the performance of the emulsion and stirring efficiency.

[0037] In this embodiment, the connecting frame 3 further includes a reinforcing rod 34, which is fixed to the mounting rod 31 and spaced below the fixed rod 32. The rotating shaft 51 is adapted to pass through both ends of the reinforcing rod 34 and is used to limit the rotation of the rotating shaft 51. The reinforcing rod 34 limits the rotation of the rotating shaft 51 in the vertical direction when it rotates within the fixed rod 32, thereby improving the stability of the rotating assembly 5 when it rotates within the fixed rod 32 and increasing the stirring efficiency.

[0038] The emulsion reaction vessel stirring device provided in this embodiment works as follows: the drive motor 2 drives the connecting frame 3 to rotate, and the rotation of the connecting frame 3 drives the first stirring wheel 41, the second stirring wheel 42 and the third stirring wheel 43 in the stirring assembly 4 to rotate simultaneously, so as to fully stir the emulsion in the reaction vessel and improve the stirring efficiency. At the same time, the rotating assembly 5 rotates in the vessel body 1 with the output end of the drive motor 2 as the axis under the drive of the connecting part 3. The scraper 53 is pushed by the inner side wall of the vessel body 1 and the flow of the emulsion, so that the rotating shaft rotates within the fixed rod 32 and the reinforcing rod 34, so that the scraper 53 scrapes against the inner side wall of the reaction vessel body 1, and stirs the emulsion in the area near the inner side wall of the stirring vessel, so that the emulsion material is fully mixed, the stirring is uniform, and the performance of the emulsion and the stirring efficiency are improved.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
