[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 6 This utility model provides a technical solution: a laboratory slurry mixing tank, including a base 1, a placement groove 2 with a downward opening on the upper side of the base 1, a container tank 3 on the placement groove 2, a vertical frame 4 fixedly connected to the upper side of the base 1, an L-shaped frame 5 slidably fitted on the inner wall of the vertical frame 4, a stirring motor 6 fixedly installed in the horizontal frame of the L-shaped frame 5, a flow guiding component 7 cooperating with the stirring motor 6 on the container tank 3, and two semi-circular anti-splash covers 8 at the upper opening of the container tank 3, the two anti-splash covers 8 combined together to form a disc located at the upper opening of the container tank 3.

[0024] In this embodiment, a vertical rod 9 is fixedly connected to the upper side of the base 1. The vertical rod 9 is located inside the vertical frame 4, and a longitudinal frame passing through the L-shaped frame 5 is located at its top. A sliding cylinder 10 that slides with the vertical rod 9 is fixedly connected inside the L-shaped frame 5. A screw 11 is rotatably connected to the upper side of the base 1. The screw 11 is located inside the vertical frame 4. An adjusting rod 21 that passes through the longitudinal frame of the L-shaped frame 5 and is located at its top is fixedly connected to the top of the screw 11. A threaded cylinder 12 that threadedly engages with the screw 11 is fixedly connected inside the L-shaped frame 5. The inner wall of the placement groove 2 is provided with four sliding grooves 15, which are arranged in a circumferential array around the central axis of the placement groove 2. The bottom of the container tank 3 is provided with a positioning ring groove 13, and the bottom wall of the placement groove 2 is provided with a positioning ring block 14 that cooperates with the positioning ring groove 13. The inner walls of the four sliding grooves 15 are slidably fitted with L-shaped clamping blocks 16. A spring 17 is fixedly connected between one side of the L-shaped clamping block 16 and the inner wall of the sliding groove 15. The top of the longitudinal side of the four L-shaped clamping blocks 16 is provided with a sloping side 18 facing the container tank 3.

[0025] Specifically, when the container tank 3 is placed in the placement slot 2 of the base 1, the positioning ring block 14 is embedded in the positioning ring slot 13 to complete the initial positioning. At the same time, the L-shaped clamping blocks 16 in the four sliding slots 15 are automatically clamped to the outer wall of the container tank 3 by means of the inclined side 18 under the elastic force of the spring 17, so as to achieve the stable fixation of the tank. Rotating the adjusting rod 21 drives the screw 11 to rotate, so that the threaded cylinder 12 that is threaded with the screw 11 drives the L-shaped frame 5 to slide up and down along the upright 9 and the sliding cylinder 10, thereby precisely adjusting the height of the stirring motor 6 and the stirring components to adapt to different stirring needs.

[0026] In this embodiment, the flow guiding assembly 7 includes a stirring rod 701 fixedly connected to the output shaft of the stirring motor 6. A flow guiding cylinder 702 is provided inside the container tank 3. The stirring rod 701 and the flow guiding cylinder 702 are on the same central axis as the center of the placement groove 2. The two splash guards 8 are fixedly connected to opposite sides by connecting pins 19 and connecting grooves 20, which cooperate with each other. The outer wall of the flow guiding cylinder 702 has multiple flow guiding holes 703 extending inward. The bottom of the container tank 3 is recessed with a conical groove 704. The upper end of the conical groove 704 is arc-shaped at the connection point with the lower end of the inner wall of the container tank 3. L-shaped connecting brackets 705 are fixedly connected to both sides of the outer wall of the flow guiding cylinder 702. The top of each of the longitudinal sides of the container is fixedly connected to a first T-shaped block 706. The two sides above the opening of the container trough 3 are fixedly connected to a second T-shaped block 707. The bottom of the two splash guards 8 is provided with a T-shaped groove 708. The first T-shaped block 706 and the second T-shaped block 707 are slidably engaged with the T-shaped groove 708. The stirring rod 701 is detachably mounted with a turbine propeller 709 and a propeller 710. The turbine propeller 709 and the propeller 710 are located at the top and bottom of the guide tube 702, respectively. The sleeves of the turbine propeller 709 and the propeller 710 are fixedly fitted with fixing bolts 711. The stirring rod 701 is provided with a plurality of linearly arrayed fixing grooves 712. The fixing bolts 711 are engaged with the fixing grooves 712.

[0027] Specifically, after the stirring motor 6 starts, the output shaft drives the stirring rod 701 to rotate. The turbine propeller 709 and the propeller 710 on the stirring rod 701 rotate accordingly. The propeller 710 is located at the bottom of the guide tube 702. When it rotates, it generates an upward thrust, pushing the slurry at the bottom of the container tank 3 upward into the guide tube 702. The turbine propeller 709 is located at the top of the guide tube 702. When it rotates, it generates a downward pressure, forcing the slurry in the guide tube 702 to flow outward through the guide hole 703 on the outer wall. After the slurry flows out of the guide tube 702, it flows downward along the inner wall of the container tank and is then drawn back in by the propeller 710. The slurry enters the guide tube 702, forming a stable circulating flow field. Two semi-circular splash guards 8 are combined into a disc shape by connecting pins 19 and connecting grooves 20, covering the opening above the container tank 3 to prevent slurry from splashing during stirring. The splash guards 8 slide with the first T-shaped block 706 of the guide tube 702 and the second T-shaped block 707 of the container tank 3 through the T-shaped groove 708 at the bottom, achieving stable installation and convenient disassembly. In addition, the turbine propeller 709 and the propeller propeller 710 are connected to the fixing groove 712 of the stirring rod 701 by fixing bolts 711, and the installation position can be adjusted or the type of propeller can be changed according to experimental requirements.

[0028] When using the device, first align the container tank 3 with the placement groove 2 of the base 1. At this time, the positioning ring block 14 on the bottom wall of the placement groove is precisely embedded in the positioning ring groove 13 at the bottom of the container tank, achieving initial positioning. At the same time, the L-shaped clamping blocks 16 in the four sliding grooves 15 on the inner wall of the placement groove, under the elastic force of the spring 17, automatically adhere to the outer wall of the container tank through the inclined edge 18 at the top of their longitudinal edge and complete the clamping, ensuring that the tank will not shake during the stirring process. Then, according to the required slurry level, rotate the adjusting rod 21 to drive the screw 11 to rotate, so that it engages with the screw thread. The threaded cylinder 12 drives the L-shaped frame 5 to slide up and down along the upright 9 and the slide cylinder 10, adjusting the stirring motor 6 and stirring assembly to a suitable height. Then, the stirring assembly is assembled, with the turbine propeller 709 and the propeller 710 fitted onto the stirring rod 701. The fixing bolts 711 on the sleeve engage with the fixing grooves 712 on the periphery of the stirring rod, fixing them to the top and bottom positions of the guide cylinder 702, respectively. The guide cylinder 702 is then slid into the T-groove 708 of the splash guard 8 via the first T-shaped block 706 of the L-shaped connecting frame 705, while the container tank... The second T-shaped block 707 at the opening is also embedded in the T-shaped groove of the splash guard. Finally, the two semi-circular splash guards are combined into a disc shape through the connecting pin 19 and the connecting groove 20 to complete the overall assembly. After starting the stirring motor 6, the stirring rod 701 drives the turbine propeller 709 and the propeller 710 to rotate synchronously. The propeller generates an upward thrust at the bottom of the guide tube, pushing the slurry in the conical groove 704 at the bottom of the container tank upward into the guide tube. The turbine propeller forms a downward pressure at the top of the guide tube, forcing the slurry to flow out through the guide hole 703 on the outer wall of the guide tube and into the tank. The slurry diffuses along the edge of the tank, then sinks to the bottom along the tank wall, forming a three-dimensional flow state of "downward pushing and upward pressure + guiding circulation". The arc transition design of the conical tank reduces dead corners where the slurry will stagnate. During the stirring process, the splash guard effectively prevents the slurry from splashing, while the multi-layer fixed structure ensures the stable operation of each component. If the stirring effect needs to be adjusted, the position of the blade can be adjusted by loosening the fixing bolts, or the height of the stirring assembly can be changed by adjusting the rod. After the stirring is completed, the splash guard and stirring assembly can be removed by reversing the operation. The container tank can be taken out for further processing by loosening the L-shaped clamp.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
