Description

Technical Field

[0001] The utility model relates to the field of water washing devices, in particular to a high-efficiency water washing device for dimer acid. Background Art

[0002] Dimer acid is a viscous liquid from light yellow to dark brown, mainly a carboxylic acid mixture obtained by the dimerization reaction of unsaturated bonds between molecules of octadecadienoic acid (mainly oleic acid). Dimer acid has a relatively high molecular weight and good thermal stability, chemical stability and plasticity, so it has a wide range of applications in many fields. During the production process, dimer acid needs to be washed by a water washing device to remove impurities in the dimer acid through the water washing device and improve the performance of the dimer acid product.

[0003] The existing publication number: CN213761536U discloses a high-efficiency water washing device for dimer acid. Through the cooperation of a sprocket wheel, a pulley, a first bevel gear and a second bevel gear, the stirring blades and the shell rotate synchronously, thereby improving the water washing efficiency of the materials inside the shell.

[0004] When stirring dimer acid and water, the dimer acid and water are in a horizontal circulation in the water washing tank. Since the density of dimer acid is relatively low, it is easy to float on the water surface, resulting in a layering phenomenon, which is not conducive to the uniform mixing of dimer acid and water, easily reduces the contact area and reaction rate between dimer acid and water, and directly introducing dimer acid and water is also not conducive to the full contact, dispersion and mixing of dimer acid and water, and easily affects the subsequent water washing efficiency of dimer acid. Summary of the Invention

[0005] Therefore, to solve the above deficiencies, the utility model provides a high-efficiency water washing device for dimer acid to solve the above technical problems.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions: A high-efficiency water washing device for dimer acid includes a support frame, a water washing tank installed on the top of the support frame, and a motor fixedly installed on the top of the water washing tank. The bottom output shaft of the motor passes through the top end surface of the water washing tank and is connected to a first rotating shaft inside the water washing tank. A plurality of first stirring rods are installed on the side surface of the first rotating shaft. An inlet pipe is arranged on the water washing tank.

[0007] A support rod misaligned with the second rotating shaft is installed on the side surface of the fixed cover. One end of the support rod away from the fixed cover is connected to the inner side wall of the water washing tank;

[0008] A plurality of second stirring rods that are displaced from the first stirring rods are installed on the second rotating shaft, and the rotating directions of the second stirring rods and the first stirring rods are perpendicular to each other;

The connecting pipe communicates with the inside of the hot water pipes, and a feed port for introducing dimer acid is provided at one end of the connecting pipe away from the water washing tank.

Specific embodiments

[0023] In order to further explain the technical solution of the present utility model, the following will be elaborated in detail through specific embodiments.

[0024] As Figure 1 shown, the present utility model provides a high - efficiency water - washing device for dimer acid, including a support frame 1, a water - washing tank 2 locked and fixed on the top of the support frame 1, and a motor 3 locked and fixed in the middle of the top surface of the water - washing tank 2. The bottom output shaft of the motor 3 passes through the top surface of the water - washing tank 2 and is coaxially and fixedly connected to the first rotating shaft 6 inside the water - washing tank 2. A plurality of first stirring rods 7 are installed on the side surface of the first rotating shaft 6. The first stirring rods 7 can promote the horizontal circulation of dimer acid and water in the water - washing tank 2, which helps the dispersion and mixing of substances in a large range;

[0025] In this embodiment, a drain pipe 4 is fixedly penetrated and embedded in the bottom end surface of the water - washing tank 2, and a valve 5 is installed on the drain pipe 4, which is convenient for discharging the dimer acid and water in the water - washing tank 2 outward after opening the valve 5;

[0026] As Figures 1 to 5 shown, in this embodiment, a feeding pipe 13 is provided on the water - washing tank 2. A fixed cover 8 is movably installed on the first rotating shaft 6 above the first stirring rods 7. The first rotating shaft 6 can rotate horizontally inside the fixed cover 8. A second rotating shaft 9 is rotatably installed inside the fixed cover 8. The second rotating shaft 9 is connected to the first stirring rod 7 through a bevel - gear set, and the second rotating shaft 9 horizontally and movably passes through the inside of the fixed cover 8 and is rotatably connected to the inner side wall of the water - washing tank 2;

[0027] A support rod 14 misaligned with the second rotating shaft 9 is installed on the side surface of the fixed cover 8, and one end of the support rod 14 away from the fixed cover 8 is locked and fixed to the inner side wall of the water - washing tank 2;

[0028] A plurality of second stirring rods 10 offset from the first stirring rods 7 are installed on the second rotating shaft 9. The rotating directions of the second stirring rods 10 and the first stirring rods 7 are perpendicular to each other, facilitating the generation of more up-and-down convection when the second stirring rods 10 rotate, and contributing to more sufficient contact between dimer acid and water;

[0029] The feed pipe 13 includes a connecting pipe 131 penetrating and embedded in the outer top of the water washing tank 2. The connecting pipe 131 is used to introduce dimer acid and water, a plurality of hot water pipes 133 arranged in an annular equidistant distribution on the connecting pipe 131, and a spiral convex piece 134 fixedly installed inside the connecting pipe 131. The connecting pipe 131 communicates with the inside of the hot water pipes 133, and an inlet 132 for introducing dimer acid is provided at one end of the connecting pipe 131 away from the water washing tank 2. The spiral convex piece 134 is located between the hot water pipes 133 and the water washing tank 2;

[0030] In this embodiment, the bevel gear set includes a driving bevel gear 11 fixedly sleeved on the first rotating shaft 6 and a driven bevel gear 12 sleeved on the second rotating shaft 9. The bottom end surface of the driven bevel gear 12 meshes with the bottom end surface of the driving bevel gear 11 to realize the synchronous rotation of the driven bevel gear 12 driven by the driving bevel gear 11, and both the driven bevel gear 12 and the driving bevel gear 11 are arranged inside the fixed cover 8;

[0031] Among them, a set of driven bevel gear 12, second rotating shaft 9 and second stirring rod 10 are respectively arranged at the left and right ends of the bottom of the driving bevel gear 11. Both driven bevel gears 12 mesh with the bottom end surface of the driving bevel gear 11, facilitating the rotation of the two groups of second stirring rods 10 to make the dimer acid and water contact more quickly and fully;

[0032] Among them, there is a distance between the second stirring rod 10 and the inner wall of the water washing tank 2 to reduce the collision between the second stirring rod 10 and the inner wall of the water washing tank 2;

[0033] In this embodiment, the free end of the hot water pipe 133 faces away from the water washing tank 2, and the free end of the hot water pipe 133 extends obliquely outward, facilitating the rapid contact between the hot water and the dimer acid when the hot water enters the inside of the connecting pipe 131 through the water inlet pipe 133;

[0034] Specifically, during use, the hot water pipe 133 is connected to an external hot water introduction device, and the inlet 132 is connected to an external dimer acid introduction device. When the external dimer acid and water are respectively introduced into the inside of the connecting pipe 131 through the feed pipe 13 and the hot water pipe 133, they are spirally mixed under the action of the spiral convex piece 134, so as to promote the full contact and mixing of the dimer acid and water;

[0035] The mixed dimer acid and water enter the water washing tank 2 through the connecting pipe 131. By starting the motor 3 to drive the rotation of the first rotating shaft 6, the first rotating shaft 6 drives the rotation of the first stirring rod 7 and the driving bevel gear 11. When the first stirring rod 7 rotates, it can promote the horizontal circulation of the dimer acid and water in the tank, which helps to disperse and mix substances in a large range;

[0036] When the driving bevel gear 11 rotates, it drives the rotation of the driven bevel gear 12, and the driven bevel gear 12 drives the rotation of the second rotating shaft 9 and the second stirring rod 10. The second stirring rod 10 rotates vertically, and the vertical rotation generates more up and down convection, which helps the internal exchange of the dimer acid and water and reduces the layering phenomenon. The combined use of the dimer acid and water can achieve uniform mixing in three-dimensional space, increase the contact area and reaction rate between the dimer acid and water, thereby improving the water washing efficiency of the dimer acid and making the water washing process of the dimer acid more efficient;

[0037] After the water washing of the dimer acid is completed, the motor 3 is turned off to allow the dimer acid and water to stand and layer in the water washing tank 2. After standing, the hot water and dimer acid after standing and layering are discharged through the drain pipe 4 by opening the valve 5 respectively.

[0038] The above are only the preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
