Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1:

[0024] Please refer to Figures 1-5 , a rapid mixing device for chemical experiment reagents, including a mixing tank 1. Connection holes 11 are opened on both sides of the top of the mixing tank 1. A top cover 4 is installed on the top of the mixing tank 1. A stirring component 3 is arranged in the middle of the top of the top cover 4. An installation groove 41 is opened on the top cover 4, and the installation groove 41 is adapted to the top of the mixing tank 1. Connection components 6 are arranged on both sides of the top cover 4. The connection component 6 includes a connection groove 61. A moving plate 64 is slidably installed in the connection groove 61. One side of the moving plate 64 is fixedly provided with a connecting rod 65, and the connecting rod 65 corresponds to the connection hole 11. Both ends of the other side of the moving plate 64 are connected to the inner wall of the connection groove 61 through springs 63. A pull rod 62 is fixedly installed in the middle of the other side of the moving plate 64. The pull rod 62 penetrates the side wall of the connection groove 61 and is slidably connected to the connection groove 61;

[0025] The outside of the mixing tank 1 is fixedly connected with a support frame 2;

[0026] The stirring component 3 includes a motor 31. The output end of the motor 31 is connected with a rotating shaft 32. Stirring rods 34 are fixedly arranged in an array on the rotating shaft 32;

[0027] A connecting rod 35 is fixedly installed in the middle of the rotating shaft 32. First scrapers 351 are fixed at both ends of the connecting rod 35. The first scrapers 351 are inclined and fit with the inner wall of the mixing tank 1; A second scraper 33 is fixedly installed at the bottom end of the rotating shaft 32, and the second scraper 33 fits with the bottom of the inner wall of the mixing tank 1;

[0028] Specifically, the operator adds the reagents to be mixed into the interior of the mixing tank 1, and uses the stirring assembly 3 to fully mix and stir the reagents. During stirring, the motor 31 drives the rotating shaft 32 to rotate. During the rotation of the rotating shaft 32, the stirring rod 34 fixedly connected to the rotating shaft 32 can stir the reagents, prompting the reagents to be quickly mixed. The mixed reagents are discharged through the discharge port at the bottom of the mixing tank 1. The first scraper 351 connected to the rotating shaft 32 through the connecting rod 35 can rotate along the inner wall of the mixing tank 1 under the rotation of the rotating shaft 32. The rotation of the first scraper 351 can continuously scrape the residual reagents on the inner wall and clean the inner wall. The inclined first scraper 351 can guide the reagents, prompting the reagents to quickly fall to the bottom of the mixing tank 1. The second scraper 33 fixedly installed at the bottom of the rotating shaft 32 can clean the reagents at the bottom of the mixing tank 1, enabling the reagents to be quickly discharged from the discharge port;

[0029] During normal use, the top cover 4 is sleeved on the bottom of the mixing tank 1 through the installation groove 41, and the connecting rod 65 in the connecting assembly 6 is adapted to the connecting hole 11, so that the top cover 4 is fixedly installed on the top of the mixing tank 1. During the mixing of the reagents, some reagents will adhere to the rotating shaft 32 and the stirring rod 34. The operator pulls the pull rod 62, causing the pull rod 62 to drive the moving plate 64 to move inside the connecting groove 61, thereby being able to squeeze the spring 63, and at the same time driving the connecting rod 65 to move out of the connecting hole 11, facilitating the disconnection of the connection between the top cover 4 and the mixing tank 1, and then facilitating the operator to remove the top cover 4 together with the stirring assembly 3 for cleaning, avoiding the influence of the residual adhered reagents on the subsequent reagent mixing.

[0030] Embodiment 2:

[0031] To prevent the internal pressure of the mixing tank 1 from becoming too high due to the gas generated by some reagents during mixing, please refer to Figures 1-5 , on the basis of Embodiment 1, an air release pipe 5 is opened at the top of the top cover 4. A dust-proof net 51 is installed at the top of the air release pipe 5, and a frustum-shaped ventilation groove 53 is provided at the bottom of the air release pipe 5;

[0032] On both sides inside the air release pipe 5, there are moving grooves 52. A runner 56 is slidably connected in the moving grooves 52. The runner 56 is rotatably arranged at one end of the connecting arm 55. The connecting arm 55 is fixedly connected to the sphere 54. The sphere 54 is arranged above the ventilation groove 53.

[0033] The air release pipe 5 is used to connect the interior of the mixing tank 1 and the outside. After the operator adds the reagents to the interior of the mixing tank 1, the operator closes the inlet to prevent external dust, impurities, moisture, etc. from entering the tank during the reagent mixing, contaminating the reagents and affecting the experimental results;

[0034] The sphere 54 provided in the exhaust pipe 5 is made of plastic and has a relatively light mass. Under normal conditions, the sphere 54 is affected by gravity and lands on the top of the ventilation slot 53, closing the top of the ventilation slot 53. When the reagent generates gas during mixing, the gas pressure inside the mixing tank 1 increases. When the pressure inside the tank reaches a certain value, the gas pressure will push the sphere 54 upward to open, realizing automatic air release and pressure relief. When the pressure drops to the safe range, the sphere 54 closes under the action of gravity to prevent external air from carrying impurities into the mixing tank 1. During the upward movement of the sphere 54, the sphere 54 drives the rotating wheel 56 to move in the movement slot 52 through the connecting arm 55, and uses the rotation of the rotating wheel 56 in the movement slot 52 to move, reducing the friction with the movement slot 52 and avoiding the difficulty of the sphere 54 moving upward due to large friction. The movement slot 52 can guide the movement of the rotating wheel 56, and thus guide the movement of the sphere 54, avoiding the deviation of the sphere 54 when the gas pressure pushes the sphere 54 to rise, resulting in the sphere 54 not being able to accurately land on the top of the ventilation slot 53 when falling. The dust-proof net 51 provided at the bottom of the exhaust pipe 5 can protect the inside of the exhaust pipe 5, further preventing dust and impurities from entering the inside of the exhaust pipe 5.

[0035] Working principle: When the device is in use, the operator adds the reagent into the mixing tank 1 and uses the stirring assembly 3 to stir it. During the stirring process, if a large amount of gas is generated by the reagent, the gas pressure pushes the sphere 54 upward, and then the gas can pass through the ventilation slot 53 and be discharged from the exhaust pipe 5;

[0036] After the stirring is completed, the operator controls the mixed reagent to be discharged from the discharge port. During this process, the rotating shaft 32 rotates to drive the connecting rod 35 to control the first scraper 351 to rotate along the inner wall of the mixing tank 1, so that the reagent residue attached to the inner wall can be removed, and the reagent can flow downward along the first scraper 351 to the bottom of the mixing tank 1 and be cleaned by the second scraper 33 connected to the bottom of the rotating shaft 32, so that the reagent residue can be discharged from the discharge port. When cleaning the reagent residue on the stirring assembly 3, the operator pulls the pull rod 62 to drive the moving plate 64 to move along the connecting slot 61, so that the connecting rod 65 on the moving plate 64 can be removed from the connecting hole 11, facilitating the operator to remove the top cover 4 from the top of the mixing tank 1, and then facilitating the cleaning of the stirring assembly 3 to avoid the influence of reagent residue on the subsequent mixing effect of the reagent.
