Description

Technical Field

[0001] This utility model relates to the field of buffer solution preparation technology, specifically a buffer solution preparation container. Background Technology

[0002] An immunoassay analyzer is a commonly used sample analysis device. Users need to add various consumables during use, among which the washing buffer is a very important material. The washing buffer not only provides a suitable acid-base environment and electrolytes for the immune reaction, but more importantly, it removes unbound immune reactants during the reaction, terminating the continued binding of antigen and antibody. Through the nonionic surfactants in the buffer, it specifically reacts with unbound immune reactants and nonspecific interfering substances adsorbed on the solid-phase carrier, thereby removing these impurities that interfere with the immune response and ensuring that the immune reaction can occur normally.

[0003] In the preparation of cleaning buffer, solid raw materials need to be dissolved in water to form a liquid buffer solution. However, existing methods for preparing buffer solutions typically involve directly adding the raw materials into the preparation tank. When a large amount of solid raw material is added during buffer preparation, the dissolution rate is slow, the preparation time is long, and the preparation efficiency is low.

[0004] Therefore, a buffer solution preparation vessel is proposed. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 The present invention provides a technical solution: a buffer solution preparation vessel, comprising a preparation vessel body 1, as shown in the figure. Figure 1 As shown, a stirring shaft 2 is coaxially arranged inside the preparation tank body 1. A rotating tube 3 is sleeved and rotatably arranged at the bottom of the stirring shaft 2. A first stirring rod 4 is arranged on the stirring shaft 2, and a second stirring rod 5 is arranged on the rotating tube 3. When the equipment is working, the material is located inside the preparation tank body 1. While the stirring shaft 2 drives the first stirring rod 4 to rotate, the rotating tube 3 rotates in the opposite direction to drive the second stirring rod 5 to rotate, so as to fully stir the material and accelerate the dissolution of the material.

[0019] Specifically, an internal gear 6 is rotatably mounted on the lower surface of the preparation tank body 1, and the internal gear 6 is coaxially mounted with the preparation tank body 1. The stirring shaft 2 passes through the lower side wall of the preparation tank body 1 and is coaxially connected to the internal gear 6. A rotating gear 7 is coaxially connected to the bottom of the rotating tube 3. A transmission gear 8 is rotatably mounted on the lower surface of the preparation tank body 1. The transmission gear 8 meshes with the rotating gear 7 and the internal gear 6 respectively. By driving the stirring shaft 2 to rotate, the stirring shaft 2 drives the bottom internal gear 6 to rotate. Under the action of the transmission gear 8, the rotating gear 7 is driven to rotate, which in turn drives the bottom rotating tube 3 to rotate. The rotation direction of the rotating tube 3 is opposite to that of the stirring shaft 2, so as to drive the first stirring rod 4 and the second stirring rod 5 to rotate synchronously in opposite directions, thereby achieving a good stirring effect.

[0020] Specifically, a first movable ring 9 is sleeved and movably disposed on the outer surface of the stirring shaft 2, and a second movable ring 10 is sleeved and movably disposed on the outer surface of the rotating tube 3. The first stirring rod 4 is fixedly connected to the outer circumferential surface of the first movable ring 9, and the second stirring rod 5 is fixedly connected to the outer surface of the second movable ring 10. The first movable ring 9 can move up and down on the stirring shaft 2, and the second movable ring 10 can slide up and down on the rotating tube 3 to control the height of the first stirring rod 4 and the second stirring rod 5, and flexibly adjust the stirring height.

[0021] Specifically, a connecting pipe 11 is rotatably connected between the first movable ring 9 and the second movable ring 10. A limiting groove 12 is provided on the outer circumferential surface of the rotating pipe 3, extending in the same direction along the length of the rotating pipe 3. A limiting block 13 is fixedly connected to the inner circumferential surface of the second movable ring 10 at the location corresponding to the limiting groove 12. A strip-shaped through groove 14 is provided through the side wall of the stirring shaft 2, extending in the same direction along the length of the stirring shaft 2. A movable block 15 is movably disposed inside the stirring shaft 2. A connecting block is provided on the movable block 15 at the location corresponding to the strip-shaped through groove 14, and the connecting block is fixedly connected to the first movable ring 9. A transmission rod 16 is rotatably mounted on the upper surface of the movable block 15. An electric push rod 17 is provided at the upper end of the preparation tank body 1. The transmission rod 16 is connected to the electric push rod 17. The electric push rod 17 can control the movable block 15 to move up and down through the transmission rod 16. The movable block 15 can drive the first movable ring 9 to move up and down through the connecting block. The first movable ring 9 can control the second movable ring 10 to move synchronously through the connecting pipe 11, thereby synchronously adjusting the height of the first stirring rod 4 and the second stirring rod 5. Under the action of the limiting groove 12 and the limiting block 13, the second movable ring 10 can slide along the rotating pipe 3 and rotate synchronously with the rotation of the rotating pipe 3.

[0022] Specifically, the upper end of the stirring shaft 2 is coaxially connected to a drive gear 18, and the upper end of the preparation tank body 1 is provided with a protective cover 19. A drive motor 20 is fixedly connected to the outer surface of the protective cover 19. The drive motor 20 is connected to a drive gear 21 that meshes with the drive gear 18. The drive motor 20 drives the drive gear 18 to rotate through the drive gear 21, and the drive gear 18 drives the stirring shaft 2 to rotate.

[0023] In use, the drive motor 20 drives the drive gear 18 to rotate via the drive gear 21. The drive gear 18 drives the stirring shaft 2 to rotate, and the stirring shaft 2 drives the bottom inner gear 6 to rotate. Under the action of the transmission gear 8, the rotating gear 7 is driven to rotate, which in turn drives the bottom rotating tube 3 to rotate. The rotating tube 3 rotates in the opposite direction to the stirring shaft 2, so that the first stirring rod 4 and the second stirring rod 5 rotate synchronously in opposite directions. The electric push rod 17 can control the movable block 15 to move up and down via the transmission rod 16. The movable block 15 can then drive the first movable ring 9 to move up and down via the connecting block. The first movable ring 9 can control the second movable ring 10 to move synchronously via the connecting tube 11, thereby synchronously adjusting the height of the first stirring rod 4 and the second stirring rod 5. Under the action of the limiting groove 12 and the limiting block 13, the second movable ring 10 can slide along the rotating tube 3 and rotate synchronously with the rotation of the rotating tube 3.
