Problems solved by technology

When using a flask for chemical experiments, due to the small diameter of the flask, the stirring device used is a small crescent-shaped anchor paddle, which can only stir a small area in the flask. For solutions with poor fluidity and high viscosity The stirring effect is very poor, which has a great influence on the experimental results and the accuracy of the obtained experimental data is low

Embodiment 1

[0020] Such as figure 1 , figure 2 , image 3 The shown flask uses an anchor frame type stirring paddle, which is provided with a transmission shaft 3, an upper paddle hub 4 and a lower paddle hub 9 are arranged on the transmission shaft 3, and the left and right sides of the upper paddle hub 4 are respectively hinged with rectangular strip-shaped upper left Paddle 17 and upper right paddle 7, lower paddle hub 9 left and right sides are respectively hinged with the left lower paddle 14 and the right lower paddle 11 of rectangular elongated shape, the left end of left upper paddle 17 and left lower paddle 14 is respectively connected with The upper end and the lower end of the left rocker arm 16 are hinged, and the right end of the upper right paddle 7 and the lower right paddle 11 are hinged with the upper end and the lower end of the right rocker 8 respectively; The hinges of the left and right sides of the lower paddle hub 9 and the hinges of the left lower blade 14 and t...

Embodiment 2

[0025] Such as Figure 4 , Figure 5 , Figure 6 The shown flask uses an anchor frame type stirring paddle, and the difference with embodiment 1 is that the upper paddle hub 4 is fixedly connected with the transmission shaft 3; The lower end of shaft 3 can be inserted into the drive shaft slot. The drive shaft and the lower propeller hub are made of soft magnetic materials. The upper part of the drive shaft is provided with a magnet mounting part for placing magnets. The magnet mounting part is provided with a magnet that can be installed and removed 18. The magnet installation part can be a suction notch provided on the upper part of the transmission shaft. The magnet 18 can be embedded in the suction notch to attract and magnetize the transmission shaft. The magnet installation part can also be an annular shape on the upper part of the transmission shaft. The provided snap-in notch can also be without any notch, and the magnet 18 is arc-shaped and directly attracts the slo...

Embodiment 3

[0028] Such as Figure 7 , Figure 8 , Figure 9 The shown flask uses an anchor frame type stirring paddle. The difference from Example 1 is that the upper paddle hub 4 and the transmission shaft 3 are axially fixed, and the circumferential direction can be rotatably connected within a limited angle. The upper paddle hub 4 and the transmission shaft 3 circle It can be rotated and connected within an angle of 5-90°, preferably within an angle of 10-30°; the lower propeller hub 26 is in the shape of a connecting sleeve, and the lower end of the drive shaft can be inserted into the lower propeller hub, and the front side of the lower propeller hub 26 The wall is provided with an open L-shaped connection control notch 25, and the front side of the lower end of the transmission shaft 3 is provided with a cylindrical control protrusion 24 that cooperates with the L-shaped connection control notch 25. The control protrusion 24 is located at the lower end of the transmission shaft. ...

Abstract

The invention discloses an anchor frame type stirring paddle for a flask. The invention relates to a flask stirring device for chemical experiments. The stirring paddle is provided with a transmissionshaft, wherein an upper propeller hub and a lower propeller hub are arranged on the transmission shaft, a left upper blade and a right upper blade are hinged to the left side and the right side of the upper propeller hub respectively, a left lower blade and a right lower blade are hinged to the left side and the right side of the lower propeller hub respectively, left rocker arms are hinged to the left ends of the left upper blade and the left lower blade, and right rocker arms are hinged to the right ends of the right upper blade and the right lower blade; positioning surfaces, which are matched with each other and are used for limiting downward inclination angles of the left lower paddle and the right lower paddle, are arranged at the hinged parts of the left lower paddle and the rightlower paddle with the left side and the right side of the lower propeller hub and / or the hinged parts of the left lower paddle and the right lower paddle with the left rocker arm and the right rockerarm; one of the upper propeller hub and the lower propeller hub is axially and fixedly connected with the transmission shaft, and the other one is controllably and fixedly connected with the transmission shaft or moves up and down relatively. The stirring paddle is simple in structure, convenient to use, large in stirring range, good in stirring effect and high in experimental data accuracy.

Description

technical field [0001] The invention relates to a flask stirring device for chemical experiments, in detail, it is an anchor frame type stirring paddle for a flask with simple structure, convenient use, large stirring range, good stirring effect and high accuracy of experimental data. Background technique [0002] We know that in the chemical industry production process and laboratory experiments, the stirring device can make the reaction raw materials mix evenly, which plays an important role in the full reaction between the raw materials. [0003] The flask is a glass vessel with a neck used in the laboratory, and it is a container used when the amount of reagents is large and liquid substances participate in the reaction in chemical experiments. When using a flask for chemical experiments, due to the small diameter of the flask, the stirring device used is a small crescent-shaped anchor paddle, which can only stir a small area in the flask. For solutions with poor fluidit...
