Description

Technical Field

[0001] This utility model relates to the field of acidification reaction technology, specifically to an acidification reaction vessel for adjusting acidity. Background Technology

[0002] Acidification reaction is a key process in chemical, environmental protection and other fields. Its reaction efficiency and product quality directly depend on the mixing uniformity and mass transfer efficiency of the materials in the reactor. Existing acidification reactors for acid adjustment still have many technical bottlenecks in practical applications.

[0003] Traditional reactors often use single-tube direct injection or free dripping from the top of the reactor for feeding. Liquid materials tend to accumulate locally in the reactor, forming high-concentration areas. This feeding method limits the contact area between the acid and the material to be treated to the periphery of a single liquid column, resulting in slow mixing and easy stratification with a thin upper layer and a concentrated lower layer. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an acidification reactor that overcomes or at least partially solves the above technical problems.

[0005] This utility model is implemented as follows: This utility model provides an acidification reaction vessel for adjusting acidity, including a top shell, and a stirring mechanism is installed inside the top shell, the stirring mechanism including; A flow guide plate is fixedly installed on the inner wall of the top shell cavity. A flow guide groove is formed on the surface of the flow guide plate, and a liquid distribution hole is formed inside the flow guide groove. Multiple liquid distribution holes are provided. A spoiler, wherein the spoiler is fixedly installed on the inner wall of the inner cavity of the top shell, and multiple spoilers are provided; A stirring shaft is rotatably mounted inside the top shell, and a propeller blade is fixedly mounted on the upper half of the stirring shaft. An anchor-type stirring plate is fixedly installed at the bottom of the stirring shaft, and a baffle column is fixedly installed on the top of the anchor-type stirring plate, and multiple baffle columns are provided.

[0006] In one embodiment of this utility model, a bottom shell is fixedly installed at the bottom of the top shell, and a motor is fixedly installed at the bottom of the bottom shell. The output end of the motor is fixedly connected to the stirring shaft.

[0007] In one embodiment of this utility model, an mounting plate is fixedly installed at the bottom of the top shell, and a connecting rod is fixedly installed at the bottom of the mounting plate, wherein two connecting rods are provided.

[0008] In one embodiment of this utility model, a mounting block is rotatably mounted on the surface of the stirring shaft, and mounting rods are fixedly mounted on both sides of the mounting block, with the mounting rods being fixedly connected to the connecting rods.

[0009] In one embodiment of this utility model, a first bevel gear is rotatably mounted on both ends of the mounting rod, and a second bevel gear is fixedly mounted on the surface of the stirring shaft, wherein the first bevel gear meshes with the second bevel gear.

[0010] In one embodiment of the present invention, a sliding cylinder is fixedly installed at the bottom of the top shell, and two sliding cylinders are provided, with a sliding block slidably installed inside each of the two sliding cylinders.

[0011] In one embodiment of the present invention, an eccentric plate is rotatably mounted on the side of each of the two first bevel gears, and the end of the eccentric plate is rotatably connected to the bottom of the sliding block.

[0012] In one embodiment of this utility model, the surface of the top shell is provided with an output port, and the bottom of the bottom shell is fixedly installed with a support leg.

[0013] The acidification reaction vessel for adjusting acidity provided by this utility model has the following beneficial effects: 1. By setting up the flow guide channel, the liquid is dispersed into multiple fine streams or thin liquid films through the liquid distribution holes and falls, forming a full-area collision and mixing with the existing materials in the reactor. Compared with a single liquid column, the contact area can be increased and the mixing rate can be accelerated. In addition, the stirring forms a three-dimensional flow field. The built-in stirring of the reactor can accurately cut into the radial and axial flow formed by stirring, avoiding the liquid being trapped in the stirring vortex into dead corners, realizing the synchronous mixing of the upper, middle and lower layers of materials, and completely eliminating the stratification problem of the upper layer being thin and the lower layer being thick in traditional mixing.

[0014] 2. By using propeller blades and anchor-type agitators, two different types of eddies can be generated within the vessel. The propeller blades, with axial propulsion as their core function, generate strong vertical circulation when rotating at high speed, rapidly pushing the upper layer of material downwards while simultaneously lifting the lower layer upwards, breaking the stratification phenomenon of a thin upper layer and a dense lower layer. The core advantage of the anchor-type agitators is their proximity to the boundary. When rotating, they generate radial flow along the vessel wall and bottom. On one hand, they scrape up and disperse the high-concentration material deposited at the bottom of the vessel, preventing dead zones at the bottom. On the other hand, they scrape off the material adhering to the vessel wall, preventing local overheating or deterioration of the material on the wall surface. The two form a three-dimensional cross-flow field, reducing the dead zone rate of the agitator. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0019] Reference Figures 1-4This technical solution provides an acidification reactor for adjusting acidity, including a top shell 1. A stirring mechanism 2 is installed inside the top shell 1. The stirring mechanism 2 includes a guide plate 201, which is fixedly installed on the inner wall of the top shell 1. A guide groove 202 is formed on the surface of the guide plate 201, and multiple liquid distribution holes 203 are formed inside the guide groove 202. The solution is input through the top of the top shell 1, first falling onto the top of the guide plate 201, then falling through the guide groove 202, and finally through the liquid distribution holes 203, ensuring that the entire solution falls evenly into the interior of the top shell 1. Traditional liquid feeding is often done through a single pipe. Direct or free-falling liquids can easily lead to localized accumulation within the reactor. The uniform descent of the guide channel 202 fundamentally solves this problem. The guide channel 202, through the distribution holes 203, disperses the liquid into multiple fine streams or thin liquid films, creating a comprehensive collision and mixing effect with the existing materials in the reactor. Compared to a single liquid column, this increases the contact area and accelerates the mixing rate. Furthermore, the stirring creates a three-dimensional flow field. The built-in agitator in the reactor ensures that the uniformly falling liquid precisely enters the radial and axial flows generated by the stirring, preventing the liquid from being trapped in dead zones by the stirring vortex. This achieves simultaneous mixing of the upper, middle, and lower layers of materials, completely eliminating the stratification problem of a thinner upper layer and a thicker lower layer in traditional mixing processes. A baffle plate 204 is fixedly installed on the inner wall of the top shell 1. Multiple baffle plates 204 are provided. A stirring shaft 205 is rotatably installed inside the top shell 1. A propeller blade 206 is fixedly installed on the upper half of the stirring shaft 205. Anchor-type stirring blades 207 are fixedly installed at the bottom of the stirring shaft 205. A baffle column 208 is fixedly installed on the top of the anchor-type stirring blades 207. Multiple baffle columns 208 are provided. A bottom shell 3 is fixedly installed at the bottom of the top shell 1. A motor 4 is fixedly installed at the bottom of the bottom shell 3. The output end of the motor 4 is fixedly connected to the stirring shaft 205. When adjusting the acidity, the motor 4 is started, which drives the stirring shaft 205 to rotate. The rotation drives the propeller blade 206 and the anchor agitator blade 207 to rotate. The propeller blade 206 has the core function of axial flow propulsion. When rotating at high speed, it can generate strong vertical circulation flow, which quickly pushes the upper layer of material in the vessel downward and lifts the lower layer of material upward, breaking the stratification phenomenon of thin upper layer and thick lower layer. The core advantage of the anchor agitator blade 207 is that it is close to the boundary. When rotating, it can generate radial flow along the vessel wall and bottom. On the one hand, it scrapes up and disperses the high concentration of material deposited at the bottom of the vessel to prevent dead zones at the bottom of the vessel. On the other hand, it can scrape off the material adhering to the vessel wall to avoid local overheating or deterioration of the material on the wall surface. The two form a three-dimensional cross flow field, reducing the stirring dead zone rate.

[0020] Reference Figures 1-4Based on the same concept as Embodiment 1 above, this embodiment also proposes that an mounting plate 5 is fixedly installed at the bottom of the top shell 1, and a connecting rod 6 is fixedly installed at the bottom of the mounting plate 5. Two connecting rods 6 are provided. An mounting block 7 is rotatably installed on the surface of the stirring shaft 205. Mounting rods 8 are fixedly installed on both sides of the mounting block 7. The mounting rods 8 are fixedly connected to the connecting rods 6. A first bevel gear 9 is rotatably installed at both ends of the mounting rod 8. A second bevel gear 10 is fixedly installed on the surface of the stirring shaft 205. The first bevel gear 9 and the second bevel gear 10 mesh. A sliding cylinder 11 is fixedly installed at the bottom of the top shell 1. Two sliding cylinders 11 are provided. A sliding mechanism is slidably installed inside each of the two sliding cylinders 11. The moving block 12 and the two first bevel gears 9 are each rotatably mounted with an eccentric plate 13 on their sides. The ends of the eccentric plates 13 are rotatably connected to the bottom of the sliding block 12. The surface of the top shell 1 is provided with an output port 14, and the bottom shell 3 is fixedly mounted with a support leg 15. When the stirring shaft 205 rotates, the rotating stirring shaft 205 can drive the second bevel gear 10 to rotate. The rotation of the second bevel gear 10 can drive the two first bevel gears 9 to rotate. The rotation of the first bevel gears 9 can drive the eccentric plate 13 to rotate eccentrically, which in turn can drive the sliding block 12 to move downward inside the sliding cylinder 11, thereby hammering the bottom of the vessel and agitating the sediment at the bottom of the vessel.

[0021] Specifically, the working process or principle of this acidification reactor is as follows: The solution is input through the top of the top shell 1, and first falls onto the top of the guide plate 201. The solution then falls through the guide channel 202, and during the fall, it also falls through the distribution hole 203, allowing the entire solution to fall evenly into the interior of the top shell 1. Traditional liquid feeding is often done by single-pipe direct injection or free dripping, which easily leads to local accumulation of liquid in the reactor. The even falling of the guide channel 202 can fundamentally solve this problem. The guide channel 202 distributes the liquid through the distribution hole 203. The liquid is dispersed into multiple fine streams or thin liquid films, falling and forming a full-area collision and mixing with the existing materials in the reactor. Compared with a single liquid column, the contact area can be increased, the mixing rate can be accelerated, and a three-dimensional flow field can be formed with stirring. The built-in stirring of the reactor can accurately cut into the radial and axial flow formed by stirring, avoiding the liquid being trapped in dead corners by the stirring vortex, realizing the synchronous mixing of the upper, middle and lower layers of materials, and completely eliminating the stratification problem of the upper layer being thin and the lower layer being thick in traditional mixing. When adjusting the acidity, the motor 4 is started, which can drive the stirring shaft 205 to... The rotation of the stirring shaft 205 drives the propeller blades 206 and anchor-type stirring blades 207 to rotate. The propeller blades 206 have axial flow propulsion as their core function. When rotating at high speed, they can generate strong vertical circulation flow, quickly pushing the upper layer of material in the vessel downwards while simultaneously lifting the lower layer of material upwards, breaking up the stratification phenomenon of a thin upper layer and a concentrated lower layer. The core advantage of the anchor-type stirring blades 207 is their proximity to the boundary. When rotating, they can generate radial flow along the vessel wall and bottom. On the one hand, they scrape up and disperse the high-concentration material deposited at the bottom of the vessel, preventing dead zones at the bottom of the vessel. On the other hand, they can scrape off the attached material. The material adhering to the vessel wall is prevented from overheating or deteriorating locally on the wall surface. The two form a three-dimensional cross flow field, reducing the dead zone rate of stirring. When the stirring shaft 205 rotates, the rotating stirring shaft 205 can drive the second bevel gear 10 to rotate. The rotation of the second bevel gear 10 can drive the two first bevel gears 9 to rotate. The rotation of the first bevel gears 9 can drive the eccentric plate 13 to rotate eccentrically, which in turn can drive the sliding block 12 to move downward inside the sliding cylinder 11, thereby hammering the bottom of the vessel and agitating the sediment at the bottom of the vessel.
