[0048] This embodiment provides a slurry transfer tank that can reduce the amount of residue adhering to the walls of the tank 10, thus reducing the difficulty of cleaning the tank 10. For example... Figure 1 and Figure 2 As shown, the slurry transfer tank includes a tank body 10, an agitator 20, and a flexible scraper 30. The tank body 10 forms an accommodating space. The agitator 20 is coaxially arranged with the tank body 10 and can rotate relative to the tank body 10. The flexible scraper 30 is connected to the agitator 20, and the outer edge of the flexible scraper 30 is adapted to the shape of the inner sidewall of the tank body 10.

[0049] When the slurry transfer tank contains slurry, the agitator 20 rotates to fully agitate the slurry. Due to the presence of the flexible scraper 30, the flexible scraper 30 rotates simultaneously with the agitator 20. Since the shape of the flexible scraper 30 is adapted to the shape of the inner wall of the tank 10, while agitating the slurry, the flexible scraper 30 scrapes off the slurry close to the inner wall of the tank 10. In other words, the flexible scraper 30 fills the gap between the agitator 20 and the inner wall of the tank 10, preventing the slurry from adhering to the inner wall of the tank 10 without scratching it, thereby reducing the difficulty of cleaning the tank 10.

[0050] Optionally, the soft scraper 30 is made of silicone, which is wear-resistant, low-cost, and easy to replace.

[0051] Optionally, a stirring drive unit 98 is provided on the top of the tank body 10, and a stirring paddle 20 is installed at the output end of the stirring drive unit 98 to drive the stirring paddle 20 to rotate.

[0052] Optionally, such as Figure 2 As shown, the stirring paddle 20 includes a main shaft 21 and at least two blades 22. The main shaft 21 is coaxially arranged with the tank 10 and can rotate relative to the tank 10, that is, the main shaft 21 is connected to the output end of the stirring drive 98. The at least two blades 22 are arranged circumferentially along the main shaft 21, and each blade 22 has a corresponding soft scraper 30 connected to its outer edge. The arrangement of at least two blades 22 can increase the contact area between the stirring paddle 20 and the slurry, making the stirring more thorough and faster. In this embodiment, two blades 22 are provided. In other embodiments, more blades 22 can be provided, which is not limited here.

[0053] Optionally, such as Figure 2 As shown, the impeller 22 includes a vertical portion 221 and an inclined portion 222 connected together. The vertical portion 221 is parallel to and spaced apart from the main shaft 21. One end of the inclined portion 222, facing away from the vertical portion 221, is connected to the main shaft 21. The inclined portion 222 is inclined downwards from the end connected to the vertical portion 221 to the other end. The flexible scraper 30 has the same shape as the impeller 22 and protrudes radially from the impeller 22 along the stirring paddle 20. It can be understood that, as Figure 1 and Figure 2 As shown, the tank 10 includes a body 12 and a top cover 11. The upper end of the body 12 is open and forms an internal accommodating space. The bottom of the body 12 is conical. The top cover 11 is fastened to the opening of the body 12. The stirring paddle 20 is rotatably connected to the top cover 11. The above arrangement makes the shape of the paddle blade 22 basically match the shape of the body 12, and the soft scraper 30 is consistent with the shape of the paddle blade 22. This allows the soft scraper 30 corresponding to the vertical part 221 to scrape off the slurry on the inner side of the peripheral wall of the body 12, and the soft scraper 30 corresponding to the inclined part 222 to scrape off the slurry on the inner side of the bottom wall of the body 12, making the scraping more comprehensive.

[0054] Optionally, the impeller blade 22 further includes a reinforcing portion 223, one end of which is connected to the vertical portion 221, and the other end is connected to the main shaft 21. This arrangement increases the connection strength between the impeller blade 22 and the main shaft 21, preventing deformation of the impeller blade 22.

[0055] Optionally, such as Figure 1 As shown, the slurry transfer tank also includes a spray device 40, which includes a spray valve 41 and a nozzle (not shown in the figure). The spray valve 41 is installed on the top of the tank body 10; the spray valve 41 is connected to the nozzle. It can be understood that after a period of use, water can be sprayed into the tank body 10 by opening the spray valve 41 and spraying it into the tank body 10 through the nozzle. At the same time, the stirring drive 98 continues to drive the stirring paddle 20 to rotate, cleaning the tank body 10. During the cleaning process, the soft scraper 30 also contacts the inner wall of the tank body 10, resulting in a better cleaning effect.

[0056] Optionally, the nozzle is rotatably connected to the top inside the tank 10. This configuration allows for a more even and comprehensive water spray when the nozzle sprays water into the tank 10. The drive component that rotates the nozzle is not shown in the figure; this is prior art and will not be described further.

[0057] It should be noted that, as Figure 3 As shown, a discharge valve 92 is provided at the bottom of the main body 12. By opening the discharge valve 92, the slurry or wastewater after washing can be discharged from the discharge valve 92.

[0058] In addition, a circulating water channel and an interface (not shown) are provided inside the side wall of the body 12. Circulating water can enter the channel from the interface. The temperature of the body 12 can be adjusted by adjusting the temperature of the circulating water, thereby maintaining the stability of the slurry.

[0059] Meanwhile, the upper cover 11 is equipped with a feed valve 91, through which the slurry can enter the tank 10.

[0060] Optionally, such as Figure 1 As shown, the slurry transfer tank also includes a support frame 50 and casters 60. The tank body 10 is placed on the support frame 50, and casters 60 are respectively provided at the four corners of the support frame 50. By providing casters 60, the slurry transfer tank can be easily moved to a different position, facilitating the transfer of slurry.

[0061] Optionally, such as Figure 1 and Figure 3As shown, at least three support members 122 are circumferentially spaced and protruding from the tank body 10. Each support member 122 and the support frame 50 is equipped with a weight sensor 70, which is communicatively connected to the feed valve 91. It can be understood that the weight sensor 70 can be set with a weight value to control the opening and closing state of the feed valve 91, ensuring that the weight of the slurry inside the tank body 10 meets the requirements, and allowing for real-time monitoring of the slurry weight in the tank body 10 to guarantee the accuracy of the supplied weight.

[0062] Optionally, see Figure 2 and Figure 3 A sealing element 112 is provided between the top cover 11 and the body 12 to ensure the airtightness of the tank 10.

[0063] Optionally, such as Figure 3 and Figure 4 As shown, the edge of the upper cover 11 and the edge of the body 12 are locked together by a latch 80, ensuring that the upper cover 11 and the body 12 are locked together. Further, as... Figure 4 As shown, the lower edge of the upper cover 11 has a first flange 111 protruding radially outward, and the top edge of the body 12 has a second flange 121 protruding radially outward. The handle 80 includes a connected rod 82 and a screwing part 81. The rod 82 is rotatably connected to the body 12, and the screwing part 81 is threadedly connected to the rod 82. The bottom of the screwing part 81 can abut against the upper side of the first flange 111, so that the first flange 111 and the second flange 121 are tightly abutted. With the use of the sealing element 112, the connection between the upper cover 11 and the body 12 is reliable and the seal is in place.

[0064] Optionally, such as Figure 1 As shown, a vacuum valve 93 is provided on the top of the tank 10, that is, on the cover 11. The vacuum valve 93 is configured to evacuate the tank 10. Through the above configuration, the inside of the tank 10 can be evacuated to remove air from the tank and prevent the slurry from oxidizing.

[0065] Optionally, a nitrogen valve 94 is provided on the top of the tank 10, i.e., the cover 11. The nitrogen valve 94 is configured to allow nitrogen to enter the tank 10 to form an inert gas environment inside the tank 10 and protect the quality of the slurry.

[0066] Optionally, a pressure detector (not shown) is provided on the top of the tank 10, i.e., the cover 11. The nitrogen valve 94 and the vacuum valve 93 can be controlled by the pressure detector to achieve the required pressure.

[0067] Optionally, a safety valve 99 is provided on the top of the tank 10, i.e., the cover 11. The safety valve 99 is connected to a pressure detector and monitors the pressure inside the tank 10 to ensure that the pressure is within a safe range. If the pressure exceeds the specified value, the safety valve 99 will automatically open or close to protect the safety of the system and equipment.

[0068] Optionally, a spotlight 96 is provided on the top of the tank 10, i.e., the cover 11, and an observation window 95 is provided on the top of the tank 10. During the cleaning process, the spotlight 96 is used for illumination, and the cleaning status inside the tank 10 is viewed through the observation window.

[0069] Optionally, a liquid level switch 97 (also known as an RF admittance level switch) is provided on the top of the tank 10. The liquid level switch 97 is configured to alarm when the liquid level inside the tank 10 exceeds a preset value, and to trigger a safety alarm when the slurry level reaches a certain position to prevent too much or too little slurry.

[0070] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
