Description

Technical Field

[0001] The utility model relates to the technical field of sodium oleate production and manufacturing, and particularly relates to a stirring device for stirring sodium oleate. Background Art

[0002] As an anionic surfactant, sodium oleate contains long-chain fatty acid radicals and sodium ions in its molecular structure, which endows it with good surface activity, emulsifying ability and certain lubricity. However, in the production process of sodium oleate, its unique physical and chemical properties are more likely to cause a series of problems, especially during the stirring process.

[0003] Sodium oleate shows a high effect of reducing surface tension in an aqueous solution, which makes it easy to form a dense foam layer on the liquid surface during the stirring process. This foam layer not only hinders the effective operation of the stirring blades, but also may lead to uneven stirring, resulting in uneven temperature and concentration distribution in the reaction system, thus affecting the quality and output of the product.

[0004] Secondly, under high temperature and stirring, the intermolecular interaction forces of sodium oleate may change, resulting in a decrease in its solubility in the solution, which is prone to precipitation and the formation of tiny solid particles. These particles may aggregate with each other during the stirring process to further form larger lumps, causing difficulties in stirring and even solidification phenomena. In addition, the shear force and frictional force generated during the stirring process will also cause a certain degree of damage to the chemical bonds between sodium oleate molecules, releasing energy. If this energy cannot be dissipated in time, it may accumulate locally and trigger safety accidents such as explosions.

[0005] Therefore, in order to solve the problems of uneven stirring and easy solidification that easily occur during the stirring of sodium oleate in the prior art, a stirring device for stirring sodium oleate is now needed. Summary of the Utility Model

[0006] The utility model aims to provide a stirring device for stirring sodium oleate, which has a simple structure and is easy to install, can ensure the uniformity of stirring during the stirring process of sodium oleate, reduce the condensation phenomenon of sodium oleate, and improve the production quality of sodium oleate.

[0007] To achieve the above object, the utility model adopts the following technical scheme:

[0008] The utility model effectively improves the stirring efficiency of sodium oleate, ensures the stirring uniformity, improves the production quality of sodium oleate, and at the same time can reduce the heat generated by stirring to ensure production safety. Specifically, a stirring device for stirring sodium oleate is provided, which includes a dissolution tank for placing sodium oleate, a driving motor is provided at the upper end of the dissolution tank, and a temperature sensing device is provided inside the dissolution tank; a stirring shaft assembly is provided below the driving motor, and the stirring shaft assembly is electrically connected to the temperature sensing device; the lower end of the stirring shaft assembly is placed inside the dissolution tank; the stirring shaft assembly includes a main shaft, and the upper end of the main shaft is connected to the driving motor; a frame and a plurality of main stirring blades are provided on the main shaft, and the main stirring blades are placed inside the frame; a plurality of secondary stirring blades are respectively provided on the side rods on both sides of the frame, and the secondary stirring blades are arranged towards the main shaft; a plurality of fins are also provided on the outer sides of the side rods on both sides of the frame; the main stirring blade includes a first central axis, and a plurality of blades arranged circumferentially around the first central axis, and each blade is inclined at an R-degree angle with respect to the radial line passing through the center point of the first central axis; the secondary stirring blade is inclined at an R-degree angle with respect to the same-side side rod.

[0009] The principle and advantages of this solution are as follows:

[0010] This solution first uses the main stirring blades and the secondary stirring blades to form a multi-layer structure for stirring, and a plurality of fins are arranged on the outer side of the frame to increase the contact area during stirring, so as to improve the stirring efficiency and ensure the stirring uniformity. At the same time, the frame is used as both a connecting frame and can perform axial stirring, increasing the axial mixing effect, so that the stirring process can achieve both axial mixing and ensure the radial mixing effect, further improving the stirring uniformity. And the blades of the stirring blades are set to have a certain inclination angle, which can cut and disperse the sodium oleate during the stirring process, avoiding excessive aggregation of sodium oleate and causing coagulation phenomena. And using the fins and the bottom tail fins to stir in multiple directions in the middle and at the bottom can effectively reduce the obstruction of the foam layer to the stirring blades, improve the stirring efficiency of the stirring blades, and also increase the stirring force, avoid the coagulation of sodium oleate, and ensure the production quality of sodium oleate.

[0011] Further, the secondary stirring blades are arranged at intervals with the main stirring blades, and the blades of the secondary stirring blades and the main stirring blades on the same side are inclined in opposite directions. This increases the contact area of the stirring blades, and at the same time can form a multi-directional stirring force, reduce the resistance generated during stirring, and can also cut and disperse the sodium oleate during the stirring process, reducing the coagulation phenomenon.

[0012] Further, the main stirring blade includes two relatively arranged blades, and the two blades are inclined at opposite angles.

[0013] Further, the frame is a hexagonal structure, including a support rod at the top, side rods on both sides, and a connecting rod at the bottom; the fins are respectively arranged on the side rods relatively, and are arranged at an angle in the opposite direction to the side rods respectively. This ensures the stability of the frame and extends its service life. At the same time, the support rod and the connecting rod are inclined, which can also reduce the resistance during stirring and effectively reduce energy consumption.

[0014] Further, a bottom tail fin is also provided at the lower part of the connecting rod, and the bottom tail fin is arranged on each connecting rod at a 90° angle. This increases the contact area during stirring, effectively stirs the bottom in multiple directions, avoids sedimentation and condensation, and improves the stirring uniformity.

[0015] Further, three main stirring blades are provided, namely a first stirring blade, a second stirring blade and a third stirring blade; the blade structures of the first stirring blade and the second stirring blade are the same, both being cuboid structures; the blade of the third stirring blade is a trapezoidal structure. This ensures the effective rotation of the stirring blades during stirring, avoids mutual influence during the stirring process, and improves the stirring efficiency.

[0016] Further, the width of the blade is 40 - 45 mm. This can increase the stirring contact area as much as possible, reduce the resistance received at the same time, and also avoid the phenomenon of sodium oleate staying on the blade and causing condensation.

[0017] Further, there are 6 secondary stirring blades, which are respectively arranged on the side rods on both sides relatively, and the interval between the opposite secondary stirring blades is 100 - 120 mm. This ensures that the installation position of the main shaft is not affected by the secondary stirring blades, and at the same time increases the contact area of the secondary stirring blades, improving the stirring efficiency.

[0018] Further, the lengths of the fins and the bottom tail fins are both 90 - 110 mm. While increasing the contact area, it forms an effective relative rotational force to form a multi-directional rotational stirring. At the same time, during the stirring process, it can cut and disperse sodium oleate from multiple angles, improving the uniformity.

[0019] Further, the inclination angle R of the blade is 30 - 60°. This ensures the stirring uniformity, and at the same time can be dynamically adjusted according to the stirring requirements, achieving the stirring efficiency while effectively reducing energy consumption.

[0028] Embodiment 1

[0029] This embodiment is basically as shown in the appendix Figure 1 : The stirring device for stirring sodium oleate includes a dissolution tank 1 for placing sodium oleate. A feeding port 7 for feeding raw materials is provided on one side of the upper end of the dissolution tank 1. A drive motor 6 is installed on one side of the feeding port 7. The drive motor 6 is arranged on the top of the dissolution tank to save space and make it more convenient to operate the stirring shaft assembly inside. A temperature sensing device is also installed inside the dissolution tank 1. The real-time temperature inside the dissolution tank 1 during the stirring process is monitored through the temperature sensing device, and parameters such as the stirring speed and stirring direction are dynamically adjusted accordingly to ensure the effectiveness and safety of stirring.

[0030] A stirring shaft assembly 2 is installed below the drive motor 6, and the lower end of the stirring shaft assembly 2 is placed inside the dissolution tank 1. At the same time, the stirring shaft assembly 2 is electrically connected to the temperature sensing device. The rotation speed and rotation angle of the stirring shaft assembly 2 are controlled by the temperature feedback monitored by the temperature sensing device to ensure the stirring uniformity and reduce unnecessary energy consumption. A layer of anti-corrosion layer structure is also provided on the surface of the stirring shaft assembly 2. In this embodiment, the anti-corrosion layer structure can be made of corrosion-resistant and high-temperature-resistant materials such as polypropylene (PP) and Teflon (polytetrafluoroethylene, PTFE), which significantly improves the corrosion resistance and wear resistance of the stirring shaft, and at the same time reduces the difficulty of cleaning and maintenance.

[0031] As shown in the appendix Figure 2As shown, the stirring shaft assembly 2 includes a main shaft 3. The upper end of the main shaft 3 is connected to a driving motor 6. The driving motor 6 drives the main shaft 3 to rotate, thereby performing the stirring process. A frame 4 and a plurality of main stirring blades 5 are detachably installed on the lower part of the main shaft 3, and the main stirring blades 5 are located inside the frame 4.

[0032] In this embodiment, the frame 4 has an unequal-sided hexagonal structure, including a support rod 8 at the top, side rods 9 on both sides, and a connecting rod 10 at the bottom. The support rods 8 at the top are arranged on both sides of the main shaft 3 at an angle of 120° relative to each other. The connecting rods 10 at the bottom are arranged on both sides of the main shaft 3 at an angle of 120° relative to each other and are inclined at a certain angle to the horizontal plane, specifically, they can be inclined at 45°.

[0033] As shown in the attached Figure 3 As shown, the main stirring blade 5 includes a first central shaft 11 provided on the main shaft 3, and a plurality of blades 12 arranged circumferentially around the first central shaft 11. Each blade 12 is inclined at an angle of R degrees to the radial line passing through the center point of the first central shaft 11, effectively increasing the stirring contact area. At the same time, when stirring, it forms a certain angle with the contact of sodium oleate, which can cut and disperse the agglomerated sodium oleate, avoid coagulation phenomena, reduce the resistance generated during rotation, lower energy consumption, and prevent sodium oleate from staying and accumulating on the blades, ensuring full and uniform stirring. In this embodiment, each main stirring blade 5 includes two oppositely arranged blades 12 to ensure uniform rotation force during stirring, and can expand the contact area with sodium oleate, ensuring full and uniform stirring. The inclination angle R of the two blades 12 of each main stirring blade 5 is 30 - 60°. In this embodiment, the two blades 12 are oppositely arranged and inclined in opposite directions, that is, if the first blade 12 is inclined downward to the left, the second blade 12 is inclined downward to the right, forming an angle between 60 - 120° between the two blades. In this embodiment, the inclination angle R of the blade 12 can be set to 45° to ensure an effective contact area and cutting effect, and ensure the uniformity of stirring.

[0034] As shown in the attached Figure 1 and the attached Figure 2 As shown, in this embodiment, there are three main stirring blades 5, namely the first stirring blade 13, the second stirring blade 14, and the third stirring blade 15. Among them, the blade 12 structures of the first stirring blade 13 and the second stirring blade 14 are the same, both are cuboid structures; the blade of the third stirring blade 15 is a trapezoidal structure, ensuring the effective rotation of the stirring blades during stirring, avoiding mutual influence during the stirring process, and improving the stirring efficiency. The width of each blade 12 is 40 - 45 mm. In this embodiment, it is set to 43 mm to increase the contact area as much as possible while reducing the resistance.

[0035] In this embodiment, a plurality of secondary stirring blades 16 are respectively provided on the side rods 9 on both sides of the frame 4, and the secondary stirring blades 16 are arranged towards the main shaft 3. In this embodiment, there are 6 secondary stirring blades 16, which are respectively arranged on the side rods 9 on both sides relatively, that is, 3 secondary stirring blades 16 are arranged on each side rod 9, and they are arranged at intervals with the main stirring blade 5 to form a multi-layer stirring paddle, increasing the contact area during stirring, and at the same time being able to cut, disperse and stir sodium oleate at different layers. At the same time, the blades 12 of the secondary stirring blades 16 and the main stirring blade 5 on the same side are inclined in opposite directions, that is, the secondary stirring blades 16 are also inclined at an angle of R degrees with the side rod 9 on the same side, but in the opposite direction to the adjacent blades 12. In this embodiment, the interval between the opposite secondary stirring blades 16 is 100 - 120 mm, specifically set to 110 mm, to ensure that the installation position of the main shaft 3 is not affected by the secondary stirring blades 16, and at the same time increase the contact area of the secondary stirring blades 16 and improve the stirring efficiency.

[0036] A plurality of fins 17 are also provided on the outer sides of the two side rods 9 of the frame 4. In this embodiment, there are 4 fins 17, which are respectively arranged on the side rods 9 in pairs relatively, and are arranged at angles in opposite directions with the side rods 9 respectively. That is, as shown in the attached Figure 4 figure, the angles between the fins 17 on both sides and the side rods 9 are the same, but the deflection directions are opposite. While increasing the stirring contact area, different-direction cutting effects are formed, effectively dispersing and cutting sodium oleate, ensuring the stirring uniformity, and at the same time reducing the resistance received.

[0037] At the same time, two bottom tail fins 18 are also provided at the lower part of the connecting rod 10. In this embodiment, the two bottom tail fins 18 are arranged on the connecting rods 10 on both sides at an angle of 90°, that is, as shown in the attached Figure 4 figure, the angles between the two bottom tail fins 18 and the connecting rod 10 are the same, both 45°, but the directions are opposite. The bottom tail fins 18 and the fins 17 have the same length, both 90 - 110 mm, specifically set to 100 mm, to increase the contact area, effectively overcome the resistance at the same time, and improve the axial mixing effect.

[0038] The axial mixing effect during stirring can be increased through the fins 17 in the middle and bottom and the bottom tail fins 18, and the dispersed arrangement can meet the stirring forces at multiple angles and in multiple directions, ensuring the stirring uniformity.

[0039] In this embodiment, a frame structure is used as the connecting frame to ensure stability and enable axial stirring, enhancing the axial mixing effect. This allows the stirring process to achieve both axial and radial mixing effects. The main stirring blades and the secondary stirring blades are arranged at intervals to form a multi-layer structure for stirring, increasing the contact area during stirring to improve the stirring efficiency and ensure the uniformity of stirring. The blades of the stirring blades are set to have a certain inclination. During the stirring process, sodium oleate can be cut and dispersed to prevent excessive aggregation of sodium oleate and cause coagulation. Different structures and different directions of the fins 17 and the bottom tail fins 18 are used to perform axial stirring on the middle and bottom parts, which can not only increase the contact area and improve the mixing effect, but also effectively reduce the obstruction of the foam layer to the stirring blades, reduce the resistance on the stirring shaft, improve the stirring efficiency of the stirring blades, reduce energy consumption, increase the stirring force, prevent sodium oleate from coagulating, and ensure the production quality of sodium oleate.

[0040] Embodiment 2

[0041] In this embodiment, different from Embodiment 1, as shown in the appendix Figure 5 As shown, a plurality of grooves 19 are further provided on the surface of each blade 12. Each groove 19 is arranged along the length direction of the blade 12, making the surface of each blade 12 irregular, so as to increase the contact area of the blade 12 and at the same time increase the heat dissipation area, effectively reducing the temperature during stirring and improving production safety. At the same time, the depth of the provided groove 19 is relatively shallow, which can also ensure that sodium oleate can quickly slide off the uneven blade 12 without staying on the blade and causing accumulation, effectively avoiding the coagulation phenomenon and ensuring the uniformity of stirring.

[0042] Embodiment 3

[0043] In this embodiment, a rotating mechanism for adjusting the inclination angle R of the blade 12 is installed inside the first central shaft 11. The inclination angle R of each blade 12 can be set according to the stirring requirements through the rotating mechanism. In this embodiment, the setting range of the inclination angle R is 30° - 60°. This can not only enable the blade 12 to have a certain cutting and dispersing effect on sodium oleate to prevent sodium oleate from coagulating, but also increase the contact area between the blade and sodium oleate as much as possible to improve the stirring uniformity. Moreover, during the stirring process, it can also prevent excessive sodium oleate from staying on the blade, ensuring the sufficiency of stirring and mixing.

[0044] In this embodiment, the rotating mechanism can be set as shown in the appendix Figure 6As shown in the figure, it includes a main gear 20 disposed within the first central axis 11, and a plurality of driven gears 21 meshed with the main gear 20. In this embodiment, there are two driven gears 21. Of course, the specific quantity can also be adjusted according to actual requirements. For example, 3 blades 12 correspond to 3 driven gears 21, or 4 blades 12 correspond to 4 driven gears 21, etc. There is no limitation on the quantity here. The upper end of the main gear 20 is electrically connected to the main shaft 3. Each driven gear 21 is axially connected to each blade 12 respectively, and the angles of the blades 12 are uniformly set synchronously to ensure consistency and stability. By rotating the main gear 20, the rotation angles of the respective blades 12 can be precisely adjusted, thereby controlling the tilt angles of the blades 12.

[0045] In this embodiment, according to the real-time temperature in the dissolution tank 1 monitored by the temperature sensing device, the rotation speed of the stirring shaft assembly 2 can be dynamically adjusted, thereby controlling its stirring efficiency. At the same time, according to the monitored temperature, the tilt angles of the blades 12 can be further adjusted. For example, when the rotation speed is relatively low, the tilt angle of the blades 12 can be increased, that is, the blades 12 are more inclined towards the vertical direction, so as to expand the contact area of the blades 12. This can not only reduce the rotation energy consumption and the generation of heat, but also ensure sufficient stirring, effectively reduce the resistance during the stirring process, and is also applicable to a large amount of rapid mixing in the initial stage of stirring. When the rotation speed is too fast, the tilt angle of the blades 12 can be reduced, that is, the blades 12 are more inclined towards the horizontal direction. In the case of rapid rotation, the resistance brought by the agitation of the blades can be effectively reduced. At the same time, the tilt angle formed by the blades 12 can cut and disperse sodium oleate to ensure the uniformity during the stirring process, and is also applicable to the middle and late stages of stirring. When ensuring that sodium oleate does not coagulate, fine stirring is carried out, and the resistance during fine stirring is smaller and it is also more suitable for a faster rotation speed.

[0046] The above are only the embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics that are well-known in the art are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
