Description

Technical Field

[0001] This application belongs to the field of chemical raw material processing technology, and in particular relates to a chemical raw material mixing device. Background Technology

[0002] In chemical production processes, raw material mixing is a crucial step in ensuring reaction efficiency and product quality. Traditional chemical raw material mixing devices typically employ simple stirring structures, such as a single impeller.

[0003] Existing mixing devices often generate air bubbles on the liquid surface during the stirring process. If these bubbles are not eliminated in time, they will mix into the product, affecting its purity and quality. Secondly, a single impeller is insufficient to achieve thorough mixing of the raw materials, which may lead to incomplete reaction or uneven mixing, reducing production efficiency. In addition, the raw materials at the bottom of the mixing device tend to accumulate due to the low flow rate, forming dead corners, which not only reduces the degree of mixing but may also cause material waste. Furthermore, the poor flowability of the raw materials often leads to blockages or poor discharge, affecting continuous production.

[0004] Therefore, existing mixing devices cannot effectively solve key problems such as degassing, mixing, deposition, and feeding at the same time, resulting in unsatisfactory mixing effects. Utility Model Content

The degassing section effectively eliminates air bubbles on the surface of the raw material liquid in the vessel, thereby improving product purity and quality. The mixing section ensures that the raw materials are fully mixed, promotes the reaction, and improves reaction efficiency and mixing uniformity. Furthermore, the mixing section, in conjunction with the degassing section, reflux section, and feeding section, can better achieve the degree of mixing of the raw materials in the vessel.

[0028] Currently, existing mixing devices cannot effectively solve key issues such as degassing, mixing, sedimentation, and feeding simultaneously, resulting in unsatisfactory mixing effects.

[0029] To address the aforementioned problems, one embodiment of this application provides a chemical raw material mixing device, such as... Figures 1 to 4 As shown, the chemical raw material mixing device includes a support frame 1, a vessel body 2, a stirring shaft 3, and a rotary drive device (not shown in the figure). The vessel body 2 is vertically mounted on the support frame 1 and has a hollow cylindrical structure. The top of the vessel body 2 has a feed inlet 21, and the bottom has a discharge outlet 22. The length direction of the stirring shaft 3 is aligned with the height direction of the vessel body 2, and the axis of the stirring shaft 3 is collinear with the axis of the vessel body 2. From top to bottom, the stirring shaft 3 has a degassing section 31, a mixing section 32, a reflux section 33, and a feeding section 34. The degassing section 31 is used for... The mixing section 32 is used to mix the raw materials in the vessel 2 to make the raw materials react better. The reflux section 33 is used to stir the low-flow-rate raw materials at the bottom of the vessel 2 to improve the mixing degree of the raw materials and avoid the accumulation of raw materials. The feeding section 34 is used to give the raw materials a tendency to flow towards the discharge port 22. The rotary drive device is set at the top of the vessel 2. The drive end of the rotary drive device is connected to the stirring shaft 3. The rotary drive device is used to drive the stirring shaft 3 to rotate to stir the raw materials in the vessel 2.

[0030] The chemical raw material mixing device provided in this application, when in use, drives the stirring shaft 3 to rotate via a rotary drive device. The degassing section 31 can effectively eliminate air bubbles on the surface of the raw material liquid in the vessel 2, thereby improving product purity and quality. The mixing section 32 ensures that the raw materials are fully mixed, promotes the reaction, and improves reaction efficiency and mixing uniformity. The mixing section 32, together with the degassing section 31, the reflux section 33, and the feeding section 34, can better achieve the mixing degree of the raw materials in the vessel 2. The reflux section 33 stirs the low-flow-rate raw materials located at the bottom of the vessel 2 to prevent raw material accumulation, enhance mixing degree, and reduce dead zones. During feeding, the feeding section 34 provides the raw materials with a flow tendency towards the discharge port 22, ensuring smooth discharge, avoiding blockage, and improving mixing efficiency and quality. By dividing the stirring shaft 3 into the degassing section 31, the mixing section 32, the reflux section 33, and the feeding section 34, this application achieves overall optimization of the raw material mixing process, improving mixing efficiency and quality.

[0031] For example, the aforementioned rotary drive device can be a motor, which is a commonly used device in the prior art. Its specific structure and connection relationship can be set with reference to the prior art, and will not be elaborated on here.

[0032] In some embodiments of this application, such as Figures 1 to 4 As shown, the defoaming section 31 of the stirring shaft 3 is provided with at least one defoaming screen 311. The defoaming screen 311 includes a hollow frame 3111 and a wire mesh 3112 spread inside the frame 3111. One end of the frame 3111 is connected to the stirring shaft 3, and the other end of the frame 3111 extends away from the stirring shaft 3. The wire mesh 3112 can scrape off the bubbles on the surface of the raw material liquid under the drive of the stirring shaft 3.

[0033] The aforementioned frame 3111 is used to support the wire mesh 3112 and fix it to the stirring shaft 3 to ensure structural stability during stirring. When the wire mesh 3112 rotates with the stirring shaft 3, it can effectively cut the air bubbles on the liquid surface, promote the bursting and removal of air bubbles, thereby improving the degassing efficiency.

[0034] In some embodiments of this application, such as Figures 1 to 4 As shown, a scraper 3113 is provided at one end of the frame 3111 away from the stirring shaft 3. The length direction of the scraper 3113 is consistent with the height direction of the vessel body 2. The working surface of the scraper 3113 is in contact with the inner wall of the vessel body 2. The scraper 3113 is set at an angle to the tangent of the generatrix of the vessel body 2 through which the scraper 3113 passes.

[0035] When the scraper 3113 rotates with the stirring shaft 3, it can scrape along the inner wall of the vessel body 2, effectively preventing raw materials from adhering to the inner wall and forming scale. At the same time, the scraper 3113 is set at an angle to the tangent of the generatrix of the vessel body 2 through which the scraper 3113 passes, so that the scraper 3113 generates shearing force during movement, further destroying the bubble structure, enhancing the degassing effect, and promoting the peeling and dispersion of the attached substances.

[0036] In some embodiments of this application, such as Figures 1 to 4 As shown, the mixing section 32 of the stirring shaft 3 is provided with at least one stirring impeller 321. The stirring impeller 321 includes a fixing ring 3211 and blades 3212 arranged circumferentially along the fixing ring 3211. The fixing ring 3211 is coaxially arranged with the stirring shaft 3.

[0037] During rotation, the blade 3212 propels the raw material to flow radially and axially, enhancing shearing and convection between materials and improving mixing uniformity. The fixing ring 3211 ensures stable installation of the blade 3212 and guarantees smooth operation. It should be noted that the blade 3212 can be designed with an inclination angle similar to that in existing technologies to optimize the flow field distribution, avoid local turbulence or dead zones, and further improve mixing efficiency.

[0038] In some embodiments of this application, such as Figures 1 to 4 As shown, multiple impellers 321 are provided, spaced apart along the length of the stirring shaft 3.

[0039] The stirring impellers 321 are arranged at intervals along the length of the stirring shaft 3. Multiple stirring impellers 321 can stir the raw materials at different heights in the vessel body 2 in layers, forming a multi-stage shear flow field, effectively breaking the material stratification phenomenon and enhancing the longitudinal and transverse mixing effect.

[0040] In some embodiments, the staggered distribution of blades between adjacent stirring impellers 321 can further enhance the disturbance effect on materials, avoid repetitive fluid flow paths, and improve shear efficiency and mixing uniformity. By adjusting the staggered angle, the flow field distribution can be optimized, allowing materials to fully cross-mix between different levels and reducing mixing blind zones. At the same time, the staggered arrangement helps to disperse eddy current concentration phenomena, reduce the risk of local viscosity accumulation, and improve overall mixing stability.

[0041] In some embodiments of this application, such as Figures 1 to 4 As shown, at least one turbulence impeller 331 is provided on the reflux section 33 of the stirring shaft 3. One end of the turbulence impeller 331 is connected to the stirring shaft 3, and the other end of the turbulence impeller 331 extends away from the stirring shaft 3.

[0042] One end of the aforementioned turbulence impeller 331 is connected to the stirring shaft 3, and the other end of the turbulence impeller 331 extends away from the stirring shaft 3. During rotation, it guides the material to form a local vortex, which can effectively enhance the material circulation and prevent the raw material from accumulating and depositing.

[0043] In some embodiments of this application, such as Figures 1 to 4 As shown, the blade surface of the spoiler 331 has spoiler holes 3311.

[0044] The aforementioned turbulence holes 3311 can further enhance the shearing effect and turbulence intensity in the raw material when the turbulence propeller 331 rotates, further promoting the uniformity of mixing and avoiding material deposition and accumulation. At the same time, the turbulence holes 3311 can reduce the motion resistance of the turbulence propeller 331, reduce energy consumption, and avoid material back-mixing caused by local pressure concentration.

[0045] In some embodiments of this application, such as Figures 1 to 4 As shown, a turbulence fan blade 3312 is provided inside the turbulence hole 3311.

[0046] The aforementioned turbulence fan blade 3312 is fixed inside the turbulence hole 3311 and rotates synchronously with the turbulence propeller 331 to further cut the fluid to enhance the local turbulence intensity, improve the dispersion effect of the material when passing through the turbulence hole 3311, and avoid the accumulation of raw materials.

[0047] In some embodiments of this application, such as Figures 1 to 4 As shown, the feature is that there are multiple turbulence propellers 331, and the multiple turbulence propellers 331 are arranged at intervals along the circumference of the stirring shaft 3.

[0048] There are multiple turbulence impellers 331, which are spaced apart circumferentially along the stirring shaft 3. The multiple turbulence impellers 331 evenly distributed circumferentially can enhance the radial disturbance range, effectively expand the vortex coverage area, improve the overall circulation efficiency, and further suppress the formation of flow dead zones.

[0049] In some embodiments of this application, such as Figures 1 to 4 As shown, the discharge port 22 is located at the center of the bottom end of the vessel body 2, and the feeding section 34 of the stirring shaft 3 is equipped with a propeller 341.

[0050] The aforementioned propeller 341 is used to start after the chemical raw materials are mixed, pushing the uniformly mixed material along the stirring shaft 3 to the discharge port 22 to achieve efficient discharge. At the same time, the central discharge method combined with bottom flow guidance makes the raw materials discharged more thoroughly, reduces the risk of cross-contamination between batches, and improves production efficiency and product consistency.

[0051] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principles described in this application, and these improvements and modifications should also be considered within the scope of protection of this application.
