[0032] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0033] The following is for reference. Figures 1 to 4 The stirred reactor of this utility model includes:

[0034] 1. Pot body;

[0035] The stirring device includes a stirring assembly 2 and a position adjustment assembly 3. The stirring assembly 2 is adjustable in position within the vessel body 1 via the position adjustment assembly 3. The stirring assembly 2 includes a stirring rod 21 that is rotatably and vertically placed within the vessel body 1 and a stirring paddle 22 located at the lower end of the stirring rod 21. The stirring rod 21 is hollow, and a feed inlet 211 is provided at the upper part of the stirring rod 21, while a discharge outlet 212 is provided at the lower part of the stirring rod 21.

[0036] When using the above-mentioned stirred reactor, first add an appropriate amount of the first reactant into the reactor body 1, and then start the stirring assembly 2. The stirring paddle 22 stirs the first reactant. Since the stirring rod 21 is hollow and has an inlet 211 and an outlet 212, the second reactant can be introduced into the reactor body 1 through the stirring rod 21 during the stirring process. After the second reactant is sprayed out from the outlet 212, it is immediately stirred by the stirring paddle 22, so that the second reactant and the first reactant can be fully contacted. In addition, during the stirring process, the overall position of the stirring assembly 2 can be changed by the position adjustment assembly 3, so that the second reactant is evenly distributed in the reactor body 1, thereby ensuring the effective mixing of the first reactant and the second reactant. That is, in any area in the reactor body 1, the ratio of the first reactant and the second reactant is close to or reaches the preset ratio, so that the first reactant and the second reactant can react fully, and ultimately achieve the purpose of improving the quality of the reaction product. In addition, the discharge port 212 can also be set on the blade, but the design of the stirring rod 21 being hollow and having the discharge port 212 at the end can ensure that the structure of the blade is not affected by the feeding function, thus maintaining its original strength and rigidity and ensuring the stability and reliability of the stirring effect.

[0037] It should be noted that this invention is applicable to the production of various compounds, and is particularly applicable to the production of silver powder.

[0038] like Figure 1 and Figure 2 As shown in the embodiment of this utility model, the position adjustment component 3 includes a position adjustment mechanism 31 and an adjustment seat 32 that is drivenly connected to the position adjustment mechanism 31. The adjustment seat 32 forms an installation space. The stirring device also includes a feed pipe 4 and a bushing assembly 5 placed in the installation space. The bushing assembly 5 allows the upper part of the stirring rod 21 to rotatably pass through it. A storage space 56 is formed between the inner wall of the bushing assembly 5 and the stirring rod 21. The feed port 211 is connected to the storage space 56. The feed pipe 4 passes through the adjustment seat 32 and is connected to the storage space 56. The upper end of the stirring rod 21 needs to be connected to the drive motor 23 and used for feeding, so the feed port 211 is set to the side. The bushing assembly 5 is sleeved on the outside of the feed port 211 and connected to the feed pipe 4. During the rotation of the stirring rod 21, the bushing assembly 5 is in a relatively stationary state, and the feed pipe 4 is also in a relatively stationary state, which facilitates the setting of the feeding device. The position adjustment mechanism 31 can move freely within a certain space. The adjustment seat 32 is connected to the position adjustment mechanism 31. The position adjustment mechanism 31 drives the adjustment seat 32 to move, thereby driving the stirring assembly 2 connected to the adjustment seat 32. The movable and adjusting seat 32 can also fix the bushing assembly 5 to prevent the fixed bushing assembly 5 from rotating. It is understood that when the stirring rod 21 rotates to a certain angle, the feed inlet 211 and the feed pipe 4 will be misaligned. The reactants in the feed pipe 4 cannot be discharged in time, resulting in increased pressure in the feed pipe 4. There is a risk of damage to the feed pipe 4 or overflow of reactants. However, the storage space 56 can accommodate some reactants. Even if the feed inlet 211 and the feed pipe 4 are misaligned, the reactants in the feed pipe 4 can be discharged normally.

[0039] like Figure 2 As shown, specifically, there are multiple feed inlets 211, which are spaced apart circumferentially along the stirring rod 21. It can be understood that when the stirring rod 21 is rotating, the relative positions of the feed inlets 211 and the feed pipe 4 opening change in real time. By setting multiple feed inlets 211, it can be ensured that at least one feed inlet 211 is positioned opposite the feed pipe 4 opening, reducing feeding resistance. Furthermore, in conjunction with the storage space 56 surrounding the stirring rod 21, reactants can enter the stirring rod 21 through the multiple feed inlets 211 along the storage space 56, thereby further improving feeding efficiency.

[0040] like Figure 2As shown in this embodiment of the invention, the bushing assembly 5 includes a sleeve 51, a bearing 52, and a shaft seal 53. A storage space 56 is formed between the inner wall of the sleeve 51 and the stirring rod 21. Bearings 52 and shaft seals 53 are provided at both ends of the storage space 56. The side of the two bearings 52 facing each other is defined as the inner end face, and the side of the two bearings 52 facing away from each other is defined as the outer end face. The shaft seal 53 is located on the inner end face of the corresponding bearing 52 and is used to seal the storage space 56. By providing a composite structure of bearings 52 and shaft seals 53 at both ends of the storage space 56, and by designing the shaft seal 53 to be located on the inner end face of the bearing 52, a stepped sealing barrier is formed. The external bearing 52 bears the main mechanical load, while the internal shaft seal 53 achieves a contact-type dynamic seal, effectively preventing the permeation of reactants into the bearing 52.

[0041] like Figure 2 As shown in this embodiment of the invention, the bushing assembly 5 further includes a sealing end cap 54 disposed at the end of the sleeve 51. A sealing ring 55 is sandwiched between the sealing end cap 54 and the bearing 52. The side of the sealing end cap 54 facing away from the sleeve 51 is used to connect the adjusting seat 32. The sealing ring 55 added between the sealing end cap 54 and the bearing 52 forms a third sealing line, creating a three-level sealing system of "shaft seal-bearing-sealing ring". The sealing end cap 54 applies radial clamping force through pre-tightening bolts, causing the sealing ring 55 to undergo elastic deformation, forming uniform contact pressure on the end face, thereby improving the reliability of the seal.

[0042] In this embodiment of the invention, the vessel body 1 is open, and the stirring assembly 2 further includes a drive motor 23 mounted on an adjustment seat 32. The upper end of the stirring rod 21 extends out of the adjustment seat 32 and is connected to the drive motor 23. Because the vessel body 1 is open, the movement of the stirring rod 21 does not interfere with the cover. The position adjustment mechanism 31 can freely drive the adjustment seat 32 to move the drive motor 23 and the stirring rod 21.

[0043] Of course, this utility model is not limited to this. The vessel body 1 can also be equipped with a cover plate, and a slot for the stirring rod 21 to move is opened on the cover plate.

[0044] In this embodiment of the invention, the position adjustment assembly 3 further includes a mounting column 33, which is disposed on the side of the vessel body 1. The position adjustment mechanism 31 includes a horizontal drive assembly and a lifting drive component 312. The lifting drive component 312 is disposed on the mounting column 33 and drives and connects to the horizontal drive assembly. The horizontal drive assembly drives and connects to the adjustment seat 32. The horizontal drive assembly is used to adjust the horizontal position of the stirring assembly 2, and the lifting drive component 312 is used to adjust the height position of the stirring assembly 2. The mounting column 33 provides support, and the horizontal drive assembly and the lifting drive component 312 adjust the position of the stirring assembly 2 along a fixed direction.

[0045] Of course, this utility model is not limited to this. A multi-axis robotic arm can be set to replace the above-mentioned mounting column 33 and drive component. The position of the stirring component 2 can also be freely adjusted by the multi-axis robotic arm.

[0046] In this embodiment of the invention, the stirring device further includes an auxiliary support assembly disposed on the mounting column 33. The auxiliary support assembly is disposed on the mounting column 33 and is used to support the horizontal drive assembly and / or the lifting drive component 312, so as to reduce the radial load borne by the drive component and protect the drive component.

[0047] Specifically, the aforementioned driving components are all telescopic driving components, such as cylinders, hydraulic cylinders, electric push rods, etc. The auxiliary support assembly can be set as a telescopic housing on the outside of the driving component. The telescopic housing can extend and retract synchronously with the telescopic driving component to share the radial load. Alternatively, the auxiliary support assembly can also be set as a telescopic rod assembly, which is arranged in parallel and spaced apart from the horizontal driving assembly. The telescopic end of the telescopic rod assembly is connected to the adjusting seat 32.

[0048] Furthermore, the horizontal drive assembly is preferably a telescopic cylinder (which can be a pneumatic cylinder or a hydraulic cylinder), and a bellows cover 35 is fitted on the outside of the telescopic rod of the telescopic cylinder. The bellows cover 35 is used to protect the telescopic rod in the telescopic cylinder from dust.

[0049] In this embodiment of the invention, a track extending along the height direction is provided on the mounting column 33, and the stirring device further includes a sliding seat 313 movably disposed along the track. A lifting drive component 312 drives and connects to the sliding seat 313, and a horizontal drive component is disposed on the sliding seat 313. The track and sliding seat 313 can improve the stability of the stirring component 2 during lifting. Similarly, a horizontally extending support plate can also be provided on the mounting column 33, and a track and slider can be provided on the support plate to improve the stability of the horizontal movement of the stirring component 2.

[0050] In this embodiment of the invention, the horizontal drive assembly includes a first horizontal drive member 311 and a second horizontal drive member. A lifting drive member 312 is driven and connected to the first horizontal drive member 311, the first horizontal drive member 311 is driven and connected to the second horizontal drive member, and the second horizontal drive member is driven and connected to the adjusting seat 32. The first horizontal drive member 311 is used to adjust the horizontal position of the stirring assembly 2 along a first horizontal direction, and the second horizontal drive member is used to adjust the horizontal position of the stirring assembly 2 along a second horizontal direction. Thus, through the first horizontal drive member 311, the second horizontal drive member, and the lifting drive member 312, the stirring paddle 22 can move freely within the vessel body 1, achieving a high degree of freedom and enabling better uniform distribution of materials within the vessel body 1.

[0051] Specifically, the second horizontal drive member can be set between the first horizontal drive member 311 and the adjusting seat 32, with the first horizontal drive member 311 driving and connecting the second horizontal drive member, which in turn drives and connects to the adjusting seat 32; alternatively, the mounting column 33 can be movably set, and the second horizontal drive member drives and connects to the mounting column 33.

[0052] It should be noted that the first horizontal direction and the second horizontal direction can be perpendicular or at other intersecting angles. Preferably, the first horizontal direction and the second horizontal direction are perpendicular to construct a spatial rectangular coordinate system. In the constructed spatial coordinate system, the first horizontal drive component 311 is used to drive the stirring paddle 22 to move along the first horizontal direction (X-axis direction), the second horizontal drive component is used to drive the stirring paddle 22 to move along the second horizontal direction (Y-axis direction), and the lifting drive component 312 is used to drive the stirring paddle 22 to move along the axial direction (Z-axis direction) of the stirring rod 21. Through the coordinated action of the three drive components, a three-degree-of-freedom motion system can be constructed. The stirred reactor also has an external control host, which is communicatively connected to the three drive components. By inputting the coordinate points corresponding to the motion system into the control host, the movement distance of each drive component can be controlled accordingly, thereby moving the stirring paddle 22 to any position within the reactor body 1.

[0053] Furthermore, the three drive components can be telescopic cylinders or a combination of servo motors and ball screws.

[0054] like Figure 3 As shown in this embodiment of the present invention, the discharge port 212 is located on the upper side of the stirring paddle 22. After the reactants flow out of the discharge port 212, they can be fully stirred by the stirring paddle 22, thus preventing the reactants from sinking directly to the bottom of the vessel.

[0055] like Figure 3 As shown in this embodiment of the invention, the stirring device further includes a nozzle 6, which is detachably disposed at the outlet 212. The nozzle 6 disperses the reactants into droplets, thereby further improving the uniformity after stirring. The nozzle 6 is detachable, allowing for disassembly, cleaning, or replacement if clogged. Specifically, the nozzle 6 can be threadedly connected to the stirring rod 21; preferably, the nozzle 6 is an atomizing nozzle to atomize the reactants, further improving the uniformity after stirring.

[0056] In this embodiment of the invention, the blade length of the stirring paddle 22 is set to be less than or equal to 1 / 3 of the inner diameter of the vessel body 1. This smaller blade length compared to conventional dimensions avoids a decrease in transmission efficiency caused by the hollow design of the stirring rod 21, ensuring the stirring rate and preventing the stirring rod 21 from shaking during stirring, thereby improving the mixing effect and ensuring the quality of the produced product. Furthermore, in conjunction with the position adjustment mechanism 31, the stirring paddle can be moved within the vessel body 1, compensating for insufficient mixing caused by the reduced blade length and ensuring the normal progress of the reaction. Specifically, the blade length of the stirring paddle 22 is preferably 1 / 5 of the inner diameter of the vessel body 1.
