[0002] Chemical reagents are relative standard substances used in chemical research and component analysis. They are an important condition for scientific and technological progress and are widely used in the synthesis, separation, qualitative and quantitative analysis of substances. Chemical reagents are indispensable in the daily work of factories, schools, hospitals and research institutes. According to their state, chemical reagents can be classified into solid reagents, liquid reagents and gaseous reagents.

[0003] In the technology of mixing liquid chemical reagents, the stirring structure in traditional mixing containers is relatively simple. During the mixing process, the stirring structure can only perform horizontal stirring. Inside the mixing container, the upper and lower liquids are prone to stratification, resulting in low mixing degree and uneven mixing. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a stirring structure and a chemical reagent mixing container, which aims to improve the problem of low mixing degree between the upper and lower liquid layers and the tendency for uneven mixing.

[0005] In a first aspect, embodiments of this application provide a stirring structure, including a stirring assembly.

[0006] The stirring assembly includes a top plate, an electric cylinder, a squeezing column, a breather valve, a rotating tube, a motor, a liquid outlet tube, and a sealing plate. The electric cylinder is connected to the top plate, the squeezing column is connected to the telescopic end of the electric cylinder, the rotating tube is rotatably connected to the top plate, the rotating tube has a liquid inlet, a stirring rod is connected to the outer wall of the rotating tube, the bottom end of the squeezing column is slidably inserted into the interior of the rotating tube, the breather valve is connected to the interior of the rotating tube, the motor is connected to the top plate, the output end of the motor is drivenly connected to the rotating tube, the liquid outlet tube is connected to the bottom end of the rotating tube, a spring is installed inside the liquid outlet tube, the sealing plate is connected to the spring, and the sealing plate seals one end of the liquid outlet tube.

[0007] In one specific implementation, a liquid inlet pipe is fixedly inserted through the top plate, and a pressure valve is fixedly inserted through the top plate, with the pressure valve and the liquid inlet pipe being symmetrically arranged.

[0008] In one specific implementation, a first U-shaped bracket is provided on the upper surface of the top plate, and the electric cylinder is fixedly connected to the upper surface of the first U-shaped bracket. The telescopic end of the electric cylinder slides through the top wall of the first U-shaped bracket.

[0009] In one specific implementation, the telescopic end of the electric cylinder is disposed on the second U-shaped bracket, and the bottom end of the second U-shaped bracket is connected to the top end of the extrusion column.

[0010] In one specific implementation, the extrusion column has a through hole at its center, the rotating tube is rotatably sleeved on the outside of the extrusion column, the through hole is connected to the inside of the rotating tube, and the breather valve is fixedly connected to the inside of the top of the through hole.

[0011] In one specific implementation, a sealing gasket is fixedly embedded in the outer wall of the extrusion column. Several sealing gaskets are provided, and the several sealing gaskets are evenly arranged and all of the several sealing gaskets are in contact with the inner wall of the rotating tube.

[0012] In one specific implementation, there are several liquid inlets, which are evenly distributed in a circular pattern, and there are several stirring rods, which are evenly arranged.

[0013] In one specific implementation, the output end of the motor is provided with a bevel gear, and the top end of the rotating tube is fixedly fitted with a bevel gear ring, which meshes with the bevel gear.

[0017] The beneficial effects of this utility model are as follows: The stirring structure and chemical reagent mixing container obtained by the above design allow the upper liquid chemical reagent to enter the rotating tube and the outlet tube through the inlet. The rotating tube is then rotated by a motor, and the extrusion column is moved downwards by an electric cylinder. The extrusion column squeezes the liquid chemical reagent inside the rotating tube and the outlet tube, causing the liquid chemical reagent inside the outlet tube to push the sealing plate away from the outlet tube, thus discharging the liquid chemical reagent from the outlet tube and allowing the upper liquid chemical reagent to be discharged into the lower liquid chemical reagent. The electric cylinder then moves the extrusion column upwards to reset, and external gas enters the rotating tube through the breather valve, causing the upper liquid chemical reagent to re-enter the rotating tube. This process can repeatedly discharge the upper liquid chemical reagent into the lower liquid chemical reagent through the rotating tube and the outlet tube, resulting in better mixing and preventing stratification between the upper and lower liquid chemical reagents, thus avoiding uneven mixing.

[0038] Please see Figure 1 Secondly, this application also provides a chemical reagent mixing container, including the above-mentioned stirring structure and mixing tank 200.

[0039] Please see Figure 1 and 2The top surface of the mixing tank 200 is completely open. The bottom wall of the mixing tank 200 is provided with support legs 210. Several support legs 210 are provided and are evenly distributed in a circle. The side wall of the mixing tank 200 is connected to the discharge valve 220. The top plate 110 is fixedly connected to the top wall of the mixing tank 200. The bottom end of the liquid inlet pipe 111 is connected to the interior of the mixing tank 200. The bottom end of the pressure valve 112 is located inside the mixing tank 200. The liquid inlet pipe 111 and the pressure valve 112 are located above several stirring rods 152. The liquid inlet pipe 111 and the pressure valve 112 will not affect the rotation of the stirring rods 152. The rotating pipe 150, the liquid outlet pipe 170 and the several stirring rods 152 all rotate inside the mixing tank 200. The rotating pipe 150 is located at the center inside the mixing tank 200.

[0040] Specifically, the working principle of this stirring structure and chemical reagent mixing container is as follows: During use, the liquid chemical reagent to be mixed can be added into the mixing tank 200 through the inlet pipe 111. The liquid chemical reagent overflows through several inlets 151, and the upper layer of liquid chemical reagent enters the rotating tube 150 and the outlet pipe 170 through the inlets 151. Then, the motor 160 is turned on to rotate the rotating tube 150, which in turn rotates the outlet pipe 170 and several stirring rods 152, thus stirring the liquid chemical reagent. Then, the electric cylinder 120 is turned on, causing the extrusion column 130 to move downwards. The extrusion column 130 moves downwards inside the rotating tube 150, passing over several inlets 151. The extrusion column 130 extrudes the liquid chemical reagent inside the rotating tube 150 and the outlet pipe 170, pushing the liquid chemical reagent inside the outlet pipe 170. The sealing plate 180 moves away from the outlet pipe 170, causing the liquid chemical reagent inside the outlet pipe 170 to be discharged. This allows the upper liquid chemical reagent to be discharged into the lower liquid chemical reagent. The electric cylinder 120 drives the squeezing column 130 to move upward. The sealing plate 180 is reset under the action of the spring 171 and the internal pressure of the mixing tank 200. The pressure inside the rotating tube 150 decreases, and the breather valve 140 opens. External gas enters the rotating tube 150 through the breather valve 140 and the through hole 131. When the squeezing column 130 moves above the inlet 151, the upper liquid chemical reagent will re-enter the rotating tube 150. This process can repeatedly discharge the upper liquid chemical reagent into the lower liquid chemical reagent through the rotating tube 150 and the outlet pipe 170, resulting in better mixing and preventing stratification between the upper and lower liquid chemical reagents, thus avoiding uneven mixing.
