Description

Technical Field

[0001] This utility model relates to the field of chemical mixing tank technology, specifically a chemical mixing tank that can fully and evenly mix substances. Background Technology

[0002] A chemical stirred tank is a reaction vessel widely used in the chemical industry. It is mainly used for various chemical reaction processes such as mixing, dissolving, emulsifying, and polymerization. It uses the rotation of a stirrer to cause materials to flow inside the tank, thereby achieving uniform mixing between materials and promoting the transfer of heat and matter. In some chemical production processes, raw material powder is added to the inside of the stirred tank, and after it reacts and dissolves fully with the mixture, it can be completely discharged.

[0003] Regarding chemical mixing vessels that achieve thorough and uniform mixing, a search revealed a public disclosure (publication) number: CN218962383U. This chemical mixing vessel, capable of multi-directional mixing, includes a vessel body, an inlet, and a hopper. The inlet is located on the upper side of the vessel body, and the hopper is fixed to the side wall of the vessel body. The outlet end of the hopper is connected to the inlet. The vessel also includes a rotating plate, a bevel gear, a bevel gear ring, a motor, and a vertical stirring rod. The vertical stirring rod can rotate along the rotating plate to achieve revolution or rotation, thereby greatly improving mixing efficiency, eliminating dead zones in the mixing process, effectively improving the mixing quality, and featuring a simple and reliable mixing structure. However, this chemical mixing vessel still has shortcomings in actual use. The feed inlet is not equipped with a crushing structure. Due to moisture during storage, the raw material powder may clump together. When the raw material powder is added into the vessel from the feed inlet and comes into contact with the mixed liquid, the clumped raw material powder cannot fully contact the mixed liquid, resulting in uneven mixing. In addition, during the mixing process, the liquid flow at the inner wall of the vessel is relatively slow, which can easily form dead zones. Air bubbles will accumulate in the inner wall area of ​​the vessel. Furthermore, liquid surface fluctuations will exacerbate the generation of air bubbles. The horizontal stirring rod is far from the inner wall of the vessel and cannot remove the generated air bubbles. As a result, the raw material powder wrapped in the air bubbles and the raw material powder adsorbed on the surface cannot be mixed evenly with the liquid. Utility Model Content

The mixing component can stir and mix the mixture and the raw material powder. Multiple bubble scraping rings rotate with the curved stirring blades to scrape away the air bubbles on the inner wall of the chemical mixing vessel body, preventing the air bubbles from wrapping and adsorbing the raw material powder, and ensuring that the raw material powder can be fully and evenly mixed with the mixture.

Detailed Implementation

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] Example

[0027] like Figures 1-7 As shown, a chemical mixing vessel for thorough and uniform mixing includes: a chemical mixing vessel body 1, a feed box 101 installed on one side of the top of the chemical mixing vessel body 1, support rods 102 installed on the four sides of the bottom of the chemical mixing vessel body 1, a crushing assembly disposed in the feed box 101, the crushing assembly including: a crushing motor 2, a rotating shaft 201 and a crushing rod 202, and a mixing assembly disposed inside the chemical mixing vessel body 1, the mixing assembly including: a motor base 3, a stirring motor 301, a stirring shaft 302, a mounting head 303, curved stirring blades 304, a through hole 305 and a bubble scraper ring 306.

[0028] The feed box 101 is provided with a feed inlet 103 at the top, and a feed pipe 104 is installed on one side of the top of the chemical mixing tank body 1. Both the feed pipe 104 and the feed inlet 103 are threaded with a sealing cover 105. A filter screen plate 106 is installed inside the feed box 101 near the bottom, and the crushing rod 202 is located on top of the filter screen plate 106.

[0029] When using the chemical mixing tank body 1, loosen and remove the sealing cap 105 at the top of the feed pipe 104 and the feed port 103, add the mixture into the chemical mixing tank body 1 through the feed pipe 104, and then add the raw material powder into the feed box 101 through the feed port 103, so that the raw material powder falls onto the filter screen plate 106. The raw material powder smaller than the mesh size of the filter screen plate 106 will fall into the chemical mixing tank body 1 and contact the mixture, while the agglomerated raw material powder larger than the mesh size of the filter screen plate 106 will be isolated and contact the crushing rod 202. During the raw material powder feeding process, the agglomerated raw material powder is filtered out to prevent the agglomerated raw material powder from falling into the chemical mixing tank body 1.

[0030] In this implementation plan: According to CN218962383U, a multi-directional mixing chemical mixing vessel is disclosed. The feed inlet does not have a crushing structure. Due to moisture during storage, the raw material powder may clump together. When the raw material powder is added into the vessel from the feed inlet and comes into contact with the mixed liquid, the clumped raw material powder cannot fully contact the mixed liquid, resulting in uneven mixing. In addition, during the mixing process, the liquid flow at the inner wall of the vessel is relatively slow, which easily forms dead zones. Bubbles will accumulate in the inner wall area of ​​the vessel. Liquid surface fluctuations will also aggravate the generation of bubbles. The horizontal stirring rod is far from the inner wall of the vessel and cannot remove the generated bubbles. As a result, the raw material powder wrapped in the bubbles and the raw material powder adsorbed on the surface cannot be mixed evenly with the liquid. Therefore, a crushing component and a mixing component are added.

[0031] Among them, a crushing motor 2 is installed on one side of the outer end of the feed box 101, and a rotating shaft 201 connected to the output end of the crushing motor 2 is provided inside the feed box 101. The other end of the rotating shaft 201 is rotatably connected to the inner wall of the feed box 101 through a sealed bearing. Multiple crushing rods 202 are installed on the rotating shaft 201.

[0032] After the raw material powder is added into the feed box 101, the filter screen 106 inside the feed box 101 can filter and separate the agglomerated raw material powder, and start the crushing motor 2. The crushing motor 2 drives the rotating shaft 201 to drive multiple crushing rods 202 to crush and disperse the agglomerated raw material powder on the filter screen 106. The crushed and dispersed raw material powder will fall from the filter screen 106 into the chemical mixing tank body 1 for pre-filtration and crushing treatment of the raw material powder, ensuring that the raw material powder can fully contact the mixture inside the chemical mixing tank body 1, so that the raw material powder and the mixture can be stirred evenly.

[0033] The chemical mixing vessel body 1 is equipped with a motor base 3 on its top, a stirring motor 301 on its top, and a stirring shaft 302 on its bottom output end. The stirring shaft 302 passes through the interior of the chemical mixing vessel body 1. The bottom of the stirring shaft 302 is rotatably connected to the bottom of the interior of the chemical mixing vessel body 1 through a sealed bearing. Three mounting heads 303 are installed on the stirring shaft 302. Four curved stirring blades 304 are installed on the outer side of each of the three mounting heads 303. Each of the four curved stirring blades 304 has a through hole 305. Multiple bubble scraping rings 306 are installed on the outer side of the four curved stirring blades 304. The multiple bubble scraping rings 306 are tightly fitted to the inner wall of the chemical mixing vessel body 1.

[0034] After the raw material powder and the mixture are added into the chemical mixing vessel body 1, the stirring motor 301 is started. The stirring motor 301 drives the stirring shaft 302 to drive the curved stirring blades 304 to rotate inside the chemical mixing vessel body 1, thereby mixing the mixture with the raw material powder. The curved stirring blades 304 have a large contact surface with the mixture and raw material powder, which can quickly mix the mixture with the raw material powder. The through hole 305 makes the mixture and raw material powder have good fluidity when in contact with the curved stirring blades 304, avoiding increasing the resistance of the curved stirring blades 304 and reducing the energy consumption of the stirring motor 301. During the mixing process, air bubbles will inevitably appear on the inner wall of the chemical mixing vessel body 1. When the curved stirring blades 304 rotate, they will drive multiple bubble scraping rings 306 to rotate together against the inner wall of the chemical mixing vessel body 1. The multiple bubble scraping rings 306 can scrape off the air bubbles on the inner wall of the chemical mixing vessel body 1, preventing the air bubbles from wrapping and adsorbing the raw material powder, and ensuring that the raw material powder can be fully and evenly mixed with the mixture.

[0035] The spacing between the multiple bubble scraping rings 306 is 0.1-0.2cm. This spacing is small, and the multiple bubble scraping rings 306 can contact the air bubbles on the inner wall of the chemical mixing vessel body 1. During the rotation, the air bubbles are broken, which can effectively remove the air bubbles on the inner wall of the chemical mixing vessel body 1, while also ensuring that the liquid inside the chemical mixing vessel body 1 has fluidity, so as to ensure that the mixture and raw material powder are fully stirred and mixed.

[0036] Among them, the stirring shaft 302 is equipped with a defoaming spiral blade 307, which is located at the top of the curved stirring blade 304. A liquid level window 4 is opened on the outer side of the chemical stirring vessel body 1 at the position opposite to the defoaming spiral blade 307. A transparent tempered glass 401 is embedded in the liquid level window 4, and a gap is left between the transparent tempered glass 401 and the defoaming spiral blade 307.

[0037] When adding the mixture into the chemical mixing vessel body 1, the liquid level of the mixture can be observed through the liquid level window 4. Ensure that the liquid level of the mixture does not exceed the liquid level window 4, that is, the defoaming spiral blade 307 is just at the liquid surface. When bubbles are generated on the liquid surface, the stirring shaft 302 drives the defoaming spiral blade 307 to rotate, which can break and eliminate the bubbles, thereby achieving the purpose of defoaming the liquid surface and effectively eliminating the bubbles. This solves the problem that the raw material powder and the mixture cannot be fully mixed evenly due to the influence of bubbles.

[0038] The chemical mixing tank body 1 has a discharge pipe 5 installed on the outer side of its bottom. A switch valve 501 is installed on the discharge pipe 5. After the mixture and raw material powder are thoroughly mixed inside the chemical mixing tank body 1, the switch valve 501 is opened and a collection container is placed at the bottom of the discharge pipe 5. The discharge pipe 5 can discharge the liquid inside the chemical mixing tank body 1 into the collection container.

[0039] The support rod 102 has a mounting base 6 installed at its outer end, and a control box 601 is installed on the top of the mounting base 6. Multiple control buttons 602 are provided on the outside of the control box 601.

[0040] When the crushing motor 2 and the stirring motor 301 are in use, they are connected to the control box 601 via wires. A power cord is installed at the bottom of the control box 601, and a power plug is installed at the other end of the power cord. The power plug is inserted into an external socket, so that the control box 601, the crushing motor 2, and the stirring motor 301 can be powered on. The starting and stopping of the crushing motor 2 and the stirring motor 301 can be controlled by the control button 602 on the outside of the control box 601. The control program involved in this utility model can be implemented by those skilled in the art based on the same or similar principles in the prior art. This part is not the innovation of this utility model.

[0041] Working principle:

[0042] When using the chemical mixing tank body 1, loosen and remove the sealing cap 105 at the top of the feed pipe 104 and feed inlet 103. Add the mixture into the chemical mixing tank body 1 through the feed pipe 104. Then, add the raw material powder into the feed box 101 through the feed inlet 103, allowing the raw material powder to fall onto the filter screen 106. Raw material powder smaller than the mesh size of the filter screen 106 will fall into the chemical mixing tank body 1 and contact the mixture, while agglomerated raw material powder larger than the mesh size of the filter screen 106 will be isolated and contact the crushing rod 202. During the feeding process, the clumps of raw material powder are filtered out to prevent them from falling into the chemical mixing tank body 1. The crushing motor 2 is started and drives the rotating shaft 201 to drive multiple crushing rods 202 to break up the clumps of raw material powder on the filter screen 106. The broken and dispersed raw material powder will fall from the filter screen 106 into the chemical mixing tank body 1 for pre-filtration and crushing treatment, ensuring that the raw material powder can fully contact the mixture inside the chemical mixing tank body 1, so that the raw material powder and the mixture can be stirred evenly.

[0043] After the raw material powder and the mixture are added into the chemical mixing vessel body 1, the stirring motor 301 is started. The stirring motor 301 drives the stirring shaft 302 to drive the curved stirring blades 304 to rotate inside the chemical mixing vessel body 1, thereby mixing the mixture with the raw material powder. The curved stirring blades 304 have a large contact surface with the mixture and raw material powder, which can quickly mix the mixture with the raw material powder. The through hole 305 makes the mixture and raw material powder have good fluidity when in contact with the curved stirring blades 304, avoiding increasing the resistance of the curved stirring blades 304 and reducing the energy consumption of the stirring motor 301. During the mixing process, air bubbles will inevitably appear on the inner wall of the chemical mixing vessel body 1. When the curved stirring blades 304 rotate, they will drive multiple bubble scraping rings 306 to rotate together against the inner wall of the chemical mixing vessel body 1. The multiple bubble scraping rings 306 can scrape off the air bubbles on the inner wall of the chemical mixing vessel body 1, preventing the air bubbles from wrapping and adsorbing the raw material powder, and ensuring that the raw material powder can be fully and evenly mixed with the mixture.

[0044] When adding the mixture into the chemical mixing vessel body 1, the liquid level of the mixture can be observed through the liquid level window 4. Ensure that the liquid level of the mixture does not exceed the liquid level window 4, that is, the defoaming spiral blade 307 is just at the liquid surface. When bubbles are generated on the liquid surface, the stirring shaft 302 drives the defoaming spiral blade 307 to rotate, which can break and eliminate the bubbles, thereby achieving the purpose of defoaming the liquid surface and effectively eliminating the bubbles. This solves the problem that the raw material powder and the mixture cannot be fully mixed evenly due to the influence of bubbles.
