Detailed Implementation

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0017] Example 1: As Figures 1-4 ,include: The reactor body 100 has a bottom 110 at its bottom, which is hemispherical. The stirring assembly includes a top cover 200. The bottom outer wall of the top cover 200 is detachably fixedly connected to the top outer wall of the reactor body 100 via a flange. The middle inner wall of the top cover 200 is rotatably connected to the stirring shaft 210 via a bearing. The outer wall of the stirring shaft 210 is fixedly installed with scraper blades 230 and stirring blades 220. The cleaning components are distributed on the bottom outer wall of the top cover 200 and include an annular tube 310 and a nozzle.

[0018] The specific application scenario of this embodiment is as follows: In use, the top cover 200 is first fixed to the reactor body 100 via the flange. The top cover 200 or the subsequent feeding structure is opened to add the raw materials for the electroplated aluminum adhesive, such as resin and diluent, into the reactor body 100. The stirring assembly is started, and the stirring shaft 210 rotates under external power, synchronously driving the stirring blade 220 and the scraper blade 230 to rotate. The stirring blade 220 mixes and stirs the raw materials to ensure uniform contact of each component. The scraper blade 230 rotates along with the stirring shaft 210 against the inner wall of the reactor body 100, initially scraping off the raw materials adhering to the reactor wall to avoid sticking. The hemispherical bottom 110 facilitates the accumulation of raw materials and reduces the residue of raw materials at the bottom of the reactor. After preparation is completed, the material is discharged through the subsequent discharge structure. The cleaning assembly can be used to clean the inside of the reactor in subsequent uses.

[0019] Example 2: Figure 1 and Figure 2 Heating plates 150 are evenly fixedly installed around the inner wall of the reactor body 100. The heating plates 150 are used to heat the electroplated aluminum adhesive during stirring. Support legs 140 are fixedly installed on the bottom outer wall of the reactor body 100. A discharge cylinder 120 is fixedly connected to the center of the bottom of the reactor body 100. A valve 130 is fixedly installed on the outer wall of the discharge cylinder 120.

[0020] The specific application scenario of this embodiment is as follows: During the reaction process, the heating element 150 is activated, and the heating element 150 uniformly transfers heat to the interior of the reactor body 100, controlling the temperature inside the reactor within the process range required for the preparation of the electroplated aluminum adhesive, such as the optimal temperature for resin reaction, to ensure a full and stable reaction; the support leg 140 provides stable support for the reactor body 100, preventing the reactor from shaking during the preparation process and affecting the stirring and heating effects; after the adhesive preparation is completed, the valve 130 is opened, and the material inside the reactor gathers along the hemispherical bottom 110 under the action of gravity, and is discharged at a uniform speed through the discharge cylinder 120, realizing convenient collection of materials; closing the valve 130 can interrupt the discharge, making it easy to control the discharge amount; a temperature sensor is installed on the inner wall of the reactor body 100 to detect the internal working temperature of the reactor body 100.

[0021] Example 3: Figure 3 and Figure 4A flexible scraper 231 is fixedly installed on the outer wall of the scraper blade 230. The flexible scraper 231 is attached to the inner wall of the reactor body 100 and the reactor bottom 110. The end of the flexible scraper 231 extends beyond the center of the reactor bottom 110. The stirring blade 220 is rectangular. The angle between the stirring blade 220 and the stirring shaft 210 is 30°. The surface of the stirring blade 220 is uniformly provided with through holes 221 to reduce stirring resistance and improve mixing uniformity. A servo motor 250 is fixedly installed on the top outer wall of the top cover 200. The output end of the servo motor 250 is fixedly connected to the top outer wall of the stirring shaft 210 through a coupling. A feeding funnel 240 is fixedly installed on the top outer wall of the top cover 200. An end cap 241 is detachably inserted into the top of the feeding funnel 240.

[0022] The specific application scenario of this embodiment is as follows: Based on embodiments one and two, the servo motor 250 is started. The servo motor 250 drives the stirring shaft 210 to rotate precisely through the coupling. The speed can be adjusted according to the viscosity of the adhesive. When the stirring shaft 210 rotates, the flexible scraper 231 on the scraper blade 230 closely adheres to the inner wall of the reactor body 100 and the bottom 110, thoroughly scraping away the raw materials adhering to the wall. The flexible material avoids scratching the reactor wall, while ensuring that there are no dead corners in the scraping. The end of the flexible scraper 231 extends beyond... The bottom of the vessel 110 is centered to further reduce residue at the bottom; the rectangular stirring blade 220 is at a 30° angle to the stirring shaft 210, and with the through holes 221 on the surface, it can reduce the resistance of the raw material to the blade during stirring, especially for high viscosity raw materials, and allow the raw material to form convection through the through holes 221 to improve the uniformity of mixing; when adding materials, the end cover 241 is opened and the raw material is added into the vessel through the feeding funnel 240 to avoid the raw material spilling. After adding materials, the end cover 241 is closed to prevent volatile substances from overflowing or external impurities from entering the vessel.

[0023] Example 4: Figure 4 Two sets of annular pipes 310 are provided, with the two sets of annular pipes 310 distributed inside and outside each other. Spray nozzles 320 are evenly fixedly installed at the bottom of the annular pipes 310. The two sets of annular pipes 310 are fixedly installed on the bottom outer wall of the top cover 200. The two sets of top covers 200 are connected by a manifold. The outer wall of the annular pipe 310 is fixedly connected to the water inlet pipe 300. The water inlet pipe 300 is connected to an external water source through a booster pump.

[0024] The specific application scenario of this embodiment is as follows: After the adhesive preparation and material discharge are completed in the above embodiment, the external booster pump is started. The booster pump delivers clean water or special cleaning agent to the annular pipe 310 through the water inlet pipe 300. The two sets of inner and outer annular pipes 310 achieve water flow distribution through the manifold to ensure that the water pressure in the two sets of annular pipes 310 is consistent. The clean water is sprayed out through the nozzles evenly distributed at the bottom of the annular pipe 310 to form an all-round spray water flow, covering the inner wall of the reactor body 100, the bottom of the reactor 110, the stirring blades 220, the scraper blades 230 and other components, thoroughly rinsing away the residual adhesive. The wastewater after rinsing can be discharged through the discharge pipe 120 and the valve 130 is opened. After cleaning is completed, the booster pump and valve 130 are closed to prepare for the next preparation.

[0025] The working principle of this utility model is as follows: When using it, those skilled in the art open the end cap 241 of the feeding funnel 240 and add the electroplated aluminum adhesive raw materials, resin, curing agent, diluent, etc. into the reactor body 100 through the feeding funnel 240. After adding the materials, the end cap 241 is closed. Stirring and anti-sticking stage: Start the servo motor 250, which drives the stirring shaft 210 to rotate, causing the stirring blade 220 and the scraping blade 230 to move synchronously. The stirring blade 220 achieves uniform mixing of raw materials through the 30° tilt angle and the through hole 221. The flexible scraper 231 of the scraping blade 230 closely adheres to the inner wall of the reactor body 100 and the bottom of the reactor 110, scraping off the raw materials sticking to the wall in real time. Temperature control stage: According to the requirements of the adhesive preparation process, the heating element 150 on the inner wall of the reactor body 100 is activated to precisely control the temperature of the raw materials in the reactor and ensure that the reaction is full and stable; Discharge stage: After the adhesive is prepared, the valve 130 on the outer wall of the discharge cylinder 120 is opened, and the material in the vessel gathers along the hemispherical bottom 110 and is discharged and collected through the discharge cylinder 120; Cleaning stage: After the material is discharged, the booster pump is started, and the cleaning water is sprayed from the nozzle through the water inlet pipe 300 and the ring pipe 310 to rinse the internal parts of the tank in all directions. The rinsing wastewater is discharged through the discharge cylinder 120 to complete the equipment cleaning. All components involved in this utility model are connected to an external controller in a conventional manner. The above structures and principles are all general standard parts or components known to those skilled in the art.
