[0036] When in use, the volumetric flask is filled with the solution to be dissolved and then placed on the placement rack 4. The stopper of the volumetric flask is pressed by the pressure plate 8 to prevent the stopper of the volumetric flask from leaking the solution due to poor sealing. The placement rack 4 is driven to flip through the flip structure, and the placement rack 4 drives the volumetric flask to flip to accelerate the dissolution of the solution. After the dissolution is completed, the volumetric flask is removed to take out the solution, and then the volumetric flask without the stopper is placed on the placement rack 4. The external water supply device is started, and water enters the chamber from the water pipe, and then enters the volumetric flask from the spray hole 24 to clean the volumetric flask. The volumetric flask can be flipped during the cleaning process, and then the external water supply device is stopped. After the water in the volumetric flask is poured out during the flipping process, the hot air blower 11 is started, and the hot air enters the chamber from the air pipe 12 and is sprayed into the volumetric flask from the spray hole 24 for drying. Through the integrated setting, the solution dissolution, automatic cleaning and drying of the volumetric flask are completed, the efficiency of the analytical test is improved, and it has good field promotion significance and practical value.

[0037] Wherein, a liquid receiving pan 2 is provided on the frame 1 below the mounting frame 4 for receiving waste liquid, and a waste liquid discharge pipe 3 is connected to the bottom of the liquid receiving pan 2;

[0038] Specifically, the flip structure includes:

[0039] The rotating shaft 13 rotatably mounted on the frame 1 can be rotatably mounted through a bearing and a bearing seat, the mounting frame 4 is detachably connected to the rotating shaft 13, a connecting plate 9 can be welded in the middle of the top of the mounting frame 4, and the connecting plate 9 is connected to the rotating shaft 13 through a connecting bolt 14;

[0040] A driving mechanism for driving the rotating shaft 13 to rotate;

[0041] It can be understood that the rotating shaft 13 is driven to rotate by the driving mechanism, and the rotating shaft 13 drives the placement frame 4 to flip;

[0046] In a specific implementation, a plurality of compression springs 15 are fixedly connected between the upper surface of the pressing plate 8 and the top of the mounting frame 4, and welding can be adopted to compress the stopper of the volumetric flask by the force of the compression springs 15 on the pressing plate 8;

[0047] Further, an electromagnet 16 is fixedly installed on the top of the placement rack 4, which can be embedded. An iron piece 17 that is magnetically matched with the electromagnet 16 is fixed on the pressure plate 8 and can be fixed by screws. When the electromagnet 16 is energized, an attraction is generated on the iron piece 17, so that the pressure plate 8 overcomes the force of the compression spring 15 and approaches the top of the placement rack 4, so as to avoid the pressure plate 8 blocking the bottle mouth of the volumetric bottle during cleaning and drying, which is not conducive to the discharge of waste liquid in the volumetric bottle and hot air with steam;

[0057] The volumetric flask is filled with the solution to be dissolved, and the forward and reverse motor 19 is started to drive the threaded rod 10 to rotate. The threaded rod 10 drives the positioning plate 6 to move upward through the connecting plate 9 to leave space for the volumetric flask. After the volumetric flask is placed, the forward and reverse motor 19 is started again to drive the threaded rod 10 to rotate. The threaded rod 10 drives the positioning plate 6 to move downward through the connecting plate 9 until it fits with the pear-shaped flat bottom of the volumetric flask to complete the positioning of the volumetric flask. The compression spring 15 pushes the pressing plate 8 to press the stopper of the volumetric flask, and the telescopic rod 23 is started to reciprocate.

The rotating shaft 13 drives the placed The rack 4 flips back and forth, and the rack 4 drives the volumetric flask to flip, which accelerates the dissolution of the solution. After the dissolution is completed, the volumetric flask is removed to take out the solution, and then the volumetric flask without a stopper is placed on the rack 4, and the external water supply equipment is started. Water enters the chamber from the water pipe, and then enters the volumetric flask from the spray hole 24 to clean the volumetric flask. The volumetric flask can be flipped during the cleaning process, and then the external water supply equipment is stopped. After the water in the volumetric flask is poured out during the flipping process, the hot air blower 11 is started, and the hot air enters the chamber from the air pipe 12 and is sprayed into the volumetric flask from the spray hole 24 for drying.
