Description

Technical Field

[0001] This utility model belongs to the field of glycerin production technology, and in particular relates to a glycerin purification and concentration device. Background Technology

[0002] Glycerol, also known as glycerin, is an organic compound with the chemical formula C3H8O3. It is a simple polyol compound. It is a colorless, odorless, sweet-tasting, viscous liquid and is non-toxic. The glycerol backbone exists in lipids called glycerides. Due to its antibacterial and antiviral properties, it is widely used in FDA-approved wound and burn treatments. Conversely, it is also used as a bacterial culture medium. It serves as an effective biomarker for measuring liver disease. It is also widely used as a sweetener in the food industry and a humectant in pharmaceutical formulations. Because it has three hydroxyl groups, glycerol is miscible with water and has hygroscopic properties.

[0003] During the production of glycerol, it is necessary to go through purification, concentration, and distillation to obtain glycerol with high purity. For example, in the process of purifying synthetic glycerol, some chemical reagents, such as inorganic acids, flocculants, and alkali solutions, need to be added to adjust the pH value, remove impurities, and neutralize acidity. These reagents need to be stirred after addition to accelerate the mixing of raw materials. Existing mixing equipment can only perform stirring within a limited range and cannot promote efficient mixing of raw materials. Therefore, we propose a glycerol purification and concentration device. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a glycerol purification and concentration device.

[0005] To achieve the above objectives, this utility model proposes a glycerol purification and concentration device, comprising two support plates, a mixing cylinder fixedly connected between the two support plates, a support plate fixedly connected to both sides of the top of the mixing cylinder, a vertical plate fixedly connected to the top of the support plate, a oscillating stirring assembly rotatably connected between the two vertical plates, the oscillating stirring assembly oscillates and stirs the interior of the mixing cylinder, arc-shaped plates are provided on both sides of the oscillating stirring assembly, a second protrusion is fixedly connected to the side of the two arc-shaped plates that are close to each other, and two fixing rods are fixedly connected between the bottom of the arc-shaped plates and the mixing cylinder.

[0006] Preferably, the oscillating stirring assembly includes a rotating shaft rotatably connected to a vertical plate, a fixed frame fixedly connected between the two rotating shafts, a drive motor fixedly connected to the fixed frame, a vertical shaft fixedly connected to the output shaft of the drive motor, a disc fixedly sleeved on the outside of the vertical shaft, a first protrusion fixedly connected to the outside of the disc, and a plurality of stirring rods fixedly connected to the vertical shaft below the disc.

[0007] Preferably, a bearing is fitted at the end of the rotating shaft away from the fixed frame, and the bearing is fixedly connected to the vertical plate.

[0008] Preferably, the bottom of the mixing cylinder is provided with a discharge pipe, and the discharge pipe is provided with a valve.

[0009] Preferably, the first protrusion is a hemispherical structure and the second protrusion is a semi-cylindrical structure.

[0010] Preferably, the fixing frame has an n-shaped structure and the stirring rod has a C-shaped structure.

[0011] The glycerol purification and concentration apparatus proposed in this utility model can bring the following beneficial effects:

[0012] 1. The vertical shaft is driven to rotate by the drive motor on the swing stirring assembly. The vertical shaft then drives the stirring rod to stir the raw materials. The stirring rod has a C-shaped structure, so it can stir both horizontally and vertically.

[0013] 2. When the oscillating stirring assembly is stirring, the vertical shaft will drive the disc and the first protrusion to rotate and intermittently squeeze the second protrusion. After being squeezed by the second protrusion, the rotating shaft will deflect, which in turn will drive the vertical shaft to deflect. This changes the tilt angle of the stirring rod, thereby increasing the stirring range.

[0014] In summary, this solution has a simple structure and a novel design. During stirring, it can be oscillating, which increases the stirring range and facilitates more thorough and efficient mixing of raw materials. Attached Figure Description

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0029] like Figures 1-6 As shown, an embodiment of this utility model proposes a glycerol purification and concentration device, including two support plates 1, a mixing cylinder 2 fixedly connected between the two support plates 1, a support plate 3 fixedly connected to the top two sides of the mixing cylinder 2, a vertical plate 4 fixedly connected to the top of the support plate 3, a swing stirring assembly 5 rotatably connected between the two vertical plates 4, the swing stirring assembly 5 swings and stirs the inside of the mixing cylinder 2, arc-shaped plates 6 are provided on both sides of the swing stirring assembly 5, a second protrusion 7 is fixedly connected to the side of the two arc-shaped plates 6 that are close to each other, and two fixing rods 8 are fixedly connected between the bottom of the arc-shaped plates 6 and the mixing cylinder 2.

[0030] like Figure 5 As shown, the oscillating stirring assembly 5 includes a rotating shaft 501 rotatably connected to the vertical plate 4. A fixed frame 502 is fixedly connected between the two rotating shafts 501. A drive motor 503 is fixedly connected to the fixed frame 502. A vertical shaft 504 is fixedly connected to the output shaft of the drive motor 503. A disc 505 is fixedly sleeved on the outside of the vertical shaft 504. A first protrusion 506 is fixedly connected to the outside of the disc 505. A plurality of stirring rods 507 are fixedly connected to the vertical shaft 504 below the disc 505. The drive motor 503 drives the vertical shaft 504 to rotate, and the vertical shaft 504 drives the disc 505 and the stirring rods 507 to rotate. The stirring rods 507 stir the raw materials in the mixing cylinder 2. When the disc 505 rotates, it will cause the first protrusion 506 to intermittently squeeze the second protrusion 7. This will cause the entire fixed frame 502 and the rotating shaft 501 to deflect, and then drive the vertical shaft 504 and the stirring rods 507 to deflect.

[0031] like Figure 5 As shown, a bearing is fitted at the end of the rotating shaft 501 away from the fixed frame 502, and the bearing is fixedly connected to the vertical plate 4. The rotating shaft 501 rotates on the vertical plate 4 with the help of the bearing.

[0032] like Figure 2 As shown, the bottom of the mixing cylinder 2 is equipped with a discharge pipe, and a valve 9 is installed on the discharge pipe. The material can be discharged by opening the valve 9.

[0033] like Figure 5 and Figure 6 As shown, the first protrusion 506 is a hemispherical structure, and the second protrusion 7 is a semi-cylindrical structure.

[0034] like Figure 5 As shown, the fixed frame 502 has an n-shaped structure, and the stirring rod 507 has a C-shaped structure.

[0035] Working principle: When the raw materials are mixed in the mixing drum 2, the drive motor 503 drives the vertical shaft 504 to rotate, which in turn drives the disc 505 and the stirring rod 507 to rotate. The stirring rod 507 stirs the raw materials in the mixing drum 2, while the disc 505, when rotating, causes the first protrusion 506 to intermittently squeeze the second protrusion 7. This causes the entire fixed frame 502 and the rotating shaft 501 to deflect and swing, which in turn causes the vertical shaft 504 and the stirring rod 507 to deflect and swing. This continuous adjustment of the stirring range during stirring is beneficial to the efficient mixing of the raw materials.

Various modifications and variations can be made to this utility model by those skilled in the art.
