A pressure detector is provided at the bottom of the exhaust valve 11 at the inner cavity of the tank body 1. When the pressure detector detects that the pressure in the inner cavity of the tank body 1 is too high, the inner cavity of the tank body 1 can be exhausted and depressurized through the exhaust valve 11 to prevent the inner cavity of the tank body 1 from being too high and causing danger; a stirring component 2, the stirring component 2 is arranged in the inner cavity of the mounting box 10, and passes through the inner cavity of the tank body 1, and a stirring component 2 3 is provided on the stirring component 2; a crushing component 5, the top of the tank body 1 A crushing box 4 is fixedly connected to one side of the part, and a crushing component 5 is arranged in the inner cavity of the crushing box 4.

[0024] Specifically, such as Figure 5 、 Figure 8As shown, the stirring assembly 2 includes a motor 2.1, which is fixedly connected to the bottom of the inner cavity of the installation box 10. The output end of the motor 2.1 is fixedly connected to the driving bevel gear 2.2, and the top of the driving bevel gear 2.2 is meshed with the driven bevel gear 2.3. The top of the driven bevel gear 2.3 is rotatably connected to the top of the inner cavity of the installation box 10 through a bearing. The bottom of the driven bevel gear 2.3 is fixedly connected to the stirring shaft 2.8. The bottom of the driving bevel gear 2.2 is meshed with the driven bevel gear 2. 2.4, the bottom of the driven bevel gear 2.4 is rotatably connected to the bottom of the inner cavity of the installation box 10 through a bearing, the bottom of the driven bevel gear 2.4 is fixedly connected to the stirring drum 2.5, the stirring shaft 2.8 is slidably connected to the inner cavity of the stirring drum 2.5, and the stirring drum 2.5 passes through the top of the tank body 1 to the inner cavity, and a stirring component 2 3 is provided on the upper part of the inner cavity of the stirring shaft 2.8, and a cleaning component 2 8 is symmetrically fixedly connected to the side wall of the stirring drum 2.5, and a cleaning component 1 7 is penetrated and connected at the lower part of the stirring shaft 2.8.

[0025] A plurality of stirring rods 2.6 are uniformly fixedly connected to the side wall of the stirring drum 2.5, and a plurality of stirring blades 2.7 are uniformly fixedly connected to the side wall of the stirring rod 2.6. A stirring shaft 2.8 is longer than the stirring drum 2.5, and the stirring shaft 2.8 extends through the lower portion of the side wall of the stirring drum 2.5 and is uniformly fixedly connected to a plurality of stirring blades 2.9. The stirring blades 2.9 are uniformly formed with a plurality of through holes 2.10. The through holes 2.10 facilitate the outflow of the nano-silver slurry therefrom, reduce the resistance encountered by the stirring blades 2.9 during stirring, and enhance the stirring effect.

[0026] Specifically, such as Figure 4 、 Figure 5 As shown, the stirring component 2 3 includes a two-phase motor 3.1, which is fixedly connected to the upper part of the inner cavity of the stirring shaft 2.8. The two output ends of the two-phase motor 3.1 are fixedly connected to the rotating shaft 3.2. The rotating shaft 3.2 slides through the stirring shaft 2.8 to the outside. One end of the rotating shaft 3.2 is fixedly connected to a stirring rod 2 3.3. The side walls of the stirring rod 2 3.3 are evenly fixedly connected with a number of stirring blades 2 3.4. The stirring blade 2 3.4 is fixedly sleeved with a stirring blade 2 3.5. The stirring blade 2 3.5 can more effectively improve the stirring efficiency.

[0027] It should be noted that after the nano-silver powder and the solid and liquid additive raw materials are placed into the tank cavity, motor 1 (2.1) is started, and the active bevel gear drives the driven bevel gear 1 (2.3) and the driven bevel gear 2 (2.4) to rotate, thereby driving the stirring drum 2.5 and the stirring shaft 2.8 to rotate in opposite directions to the horizontal. At this time, the stirring drum 2.5 drives the stirring rod 1 (2.6) and the stirring blade 1 (2.7) and the stirring shaft 2.8 drives the stirring assembly 2 (3) and the stirring blade 1 (2.9) in opposite directions, causing the nano-silver slurry in the tank body 1 to move more vigorously, facilitating comprehensive mixing. At the same time, the dense arrangement of the stirring blade 1 (2.7), the stirring assembly 2 (3), and the stirring blade 1 (2.9) allows for powerful mixing and agitation of the nano-silver slurry, resulting in more uniform mixing. At the same time, the two-phase motor 3.1 is started, driving the rotating shaft 3.2 and the stirring rod 2 3.3 to rotate, which in turn drives the stirring blade 2 3.4 and the stirring blade 2 3.5 to rotate, so that the stirring components 1 2 and 2 3 combine to stir the nanosilver slurry in the inner cavity of the tank body 1, rotating it up and down and left and right, effectively preventing the nanosilver slurry from accumulating at the bottom of the tank body 1 due to a single stirring method. The stirring blade 1 2.9 is arranged at the lower portion of the inner cavity of the tank body 1, and can stir the nanosilver slurry accumulated at the bottom of the inner cavity of the tank body 1, forming a horizontal mixing flow at the bottom of the inner cavity of the tank body 1. This flow collides with the vertical mixing flow formed by the stirring component 2 3, effectively preventing the nanosilver powder and solid and liquid additive raw materials from accumulating at the bottom of the inner cavity of the tank body 1, thereby uniformly mixing the nanosilver slurry and improving the quality of the nanosilver slurry preparation.

[0028] Example 2: Please refer to Figure 1-8 The crushing assembly 5 includes a second motor 5.1, a crushing roller 5.2, a driving gear 5.3, and a driven gear 5.4. The two crushing rollers 5.2 are rotatably connected to the side wall of the inner cavity of the crushing box 4 through bearings. The driving gear 5.3 and the driven gear 5.4 are rotatably connected to the side wall of the crushing box 4 through bearings, and the driving gear 5.3 and the driven gear 5.4 are meshed and connected. The second motor 5.1 is fixedly connected to the other side wall of the crushing box 4. The output end of the second motor 5.1 passes through the side wall of the crushing box 4 and is fixedly connected to a crushing roller 5.2. The other end of the crushing roller 5.2 is fixedly connected to the driving gear 5.3, and the driven gear 5.4 is fixedly connected to one end of the other crushing roller 5.2.

[0029] Specifically, such as Figure 7As shown, the feeding control component 9 includes a feed hopper 9.1, a pressure sensor 9.2, a solenoid valve 9.3, and a cover plate 9.4. The feed hopper 9.1 is fixedly connected to the top of the tank body 1, and the bottom of the feed hopper 9.1 passes through the tank body 1 to the inner cavity. The pressure sensor 9.2 is fixedly mounted on the feed pipe of the feed hopper 9.1, and the top of the pressure sensor 9.2 fits with the bottom of the feed hopper 9.1, so that the pressure sensor 9.2 can accurately measure the weight of the raw materials in the feed hopper 9.1. The solenoid valve 9.3 is fixedly mounted on the feed pipe of the feed hopper 9.1 and is located at the bottom of the pressure sensor 9.2. A cover plate 9.4 is fixed on the top of the feed hopper 9.1. The cover plate 9.4 can prevent external pollutants from entering the feed hopper 9.1 and contaminating the raw materials during the feeding process.

[0030] It should be noted that before preparation, nano silver powder and other solid additive raw materials are fed into the inner cavity of the crushing box 4 through the feed trough 6 in proportion, and at the same time, the second motor 5.1 is started. The second motor 5.1 drives a crushing roller 5.2 to rotate, and at the same time, the crushing roller 5.2 drives the driving gear 5.3 to rotate, and the driving gear 5.3 can drive the driven gear 5.4 to rotate, thereby driving the other crushing roller 5.2 to rotate. At this time, the two crushing rollers 5.2 rotate in opposite directions, and the crushing blades on the two crushing rollers 5.2 can crush the nano silver powder and other solid additive raw materials fed from the feed trough 6. The crushing effect is good, which facilitates the subsequent stirring and mixing of the ingredients to improve the processing quality.

[0031] While the nano silver powder and other solid additive raw materials are being crushed, the remaining liquid additive raw materials are placed in the feed hopper 9.1 respectively, and the weight of the feed hopper 9.1 is accurately measured by the pressure sensor 9.2. When the liquid additive raw materials reach the required weight, the addition is stopped and the solenoid valve 9.3 is started to allow the liquid additive raw materials to enter the inner cavity of the tank body 1, effectively ensuring the accurate addition quality of each liquid additive raw material, thereby improving the production efficiency of preparing nano silver slurry.

[0032] Example 3: Please refer to Figure 1-8 The cleaning component 7 includes a fixed shaft 7.1, a mounting plate 7.2, and a cleaning scraper 7.3. The fixed shaft 7.1 is fixedly connected to the lower part of the stirring shaft 2.8. The two ends of the fixed shaft 7.1 are fixedly connected to the mounting plates 7.2. The bottom of the mounting plate 7.2 is fixedly connected to the cleaning scraper 7.3, and the bottom of the cleaning scraper 7.3 is in contact with the lower slope of the inner cavity side wall of the tank body 1.

[0033] The cleaning component 8 includes a mounting frame 8.1 and a cleaning scraper 8.2. The mounting frame 8.1 is symmetrically fixedly connected to the two side walls of the mixing drum 2.5. One side of the mounting frame 8.1 is fixedly connected to the cleaning scraper 8.2. One side of the cleaning scraper 8.2 is in contact with the inner side wall of the tank body 1.

[0034] It should be noted that while the nano-silver slurry is being stirred and prepared, the stirring shaft 2.8 drives the cleaning scraper 7.3 to scrape and clean the oblique side wall of the bottom of the inner cavity of the tank body 1, and the stirring drum 2.5 drives the cleaning scraper 8.2 to scrape and clean the side wall of the inner cavity of the tank body 1, which can effectively prevent the nano-silver powder or other additive raw materials from adhering to the inner cavity of the tank body 1 and affecting the quality of the nano-silver slurry preparation. Example

[0035] A method for using a nano silver slurry preparation device comprises the following steps: S1. Nano silver powder and other solid additive raw materials are fed into the inner cavity of the crushing box 4 in proportion through the feed trough 6. The motor 2 5.1 is started. The nano silver powder and solid additive raw materials are crushed by two crushing rollers 5.2 and then fed into the inner cavity of the tank 1 to improve the processing quality. S2. The remaining liquid additive raw materials are then put into the feed hopper 9.1, weighed by the pressure sensor 9.2, and then put into the inner cavity of the tank body 1; S3, after the nano silver powder and the solid and liquid additive raw materials are put into the inner cavity of the tank body 1, the stirring assembly 1 2 and the stirring assembly 2 3 are started, and the stirring drum 2.5 drives the stirring rod 1 2.6, the stirring blade 1 2.7 and the stirring shaft 2.8 to drive the stirring assembly 2 3 and the stirring blade 1 2.9 to rotate in opposite directions, so that the mixed liquid in the tank body 1 moves more violently, which is convenient for fully mixing the nano silver slurry; the stirring blade 2 3.4 and the stirring blade 2 3.5 in the stirring assembly 2 3 rotate, so that the stirring assembly 1 2 and the stirring assembly 2 3 are combined to stir the tank body 1. The nanosilver slurry in the inner cavity of the tank body 1 rotates up and down and left and right, effectively avoiding the situation where the nanosilver slurry accumulates at the bottom of the tank body 1 due to the excessively simple stirring method; because the stirring blade 1 2.9 is arranged at the lower part of the inner cavity of the tank body 1, the nanosilver slurry accumulated at the bottom of the inner cavity of the tank body 1 can be stirred, forming a horizontal mixing flow at the bottom of the inner cavity of the tank body 1, and colliding with the vertical mixing flow formed by the stirring component 2 3, so that the nanosilver slurry is stirred more evenly in the inner cavity of the tank body 1, thereby mixing the nanosilver slurry evenly and improving the quality of the nanosilver slurry preparation; S4. While the nano-silver slurry is being stirred, the cleaning scrapers 1 7.3 and 2 8.2 of the cleaning assembly 1 7 and the cleaning scraper 2 8 are scraping and cleaning the side walls and the oblique side walls of the bottom of the tank body 1 to prevent the nano-silver powder or other additives from adhering to the inner cavity of the tank body 1 and affecting the quality of the nano-silver slurry preparation; S5. Finally, the mixed nano-silver paste is divided and filled through the discharge pipe 12 and the valve 13.

[0036] In summary, it can be seen that the nanosilver slurry preparation equipment and method of use, before preparation, the nanosilver powder and other solid additive raw materials are crushed by the crushing component 5, and the remaining liquid additives are weighed and quantitatively added by the feeding control component 9. When the preparation starts, the nanosilver powder and other additives are mixed by the stirring component 1 2 and the stirring component 2 3, and the nanosilver slurry is mixed evenly through multi-directional stirring. While stirring, the cleaning component 1 7 and the cleaning component 2 8 clean and scrape the side wall of the inner cavity of the tank body 1 to prevent the nanosilver powder or other additive raw materials from adhering to the inner cavity of the tank body and affecting the quality of the nanosilver slurry preparation. The raw materials are stirred evenly during the preparation of the nanosilver slurry, which improves the preparation efficiency of the nanosilver slurry and the quality of the nanosilver slurry.
