Description

Technical Field

[0001] This utility model belongs to the field of liquid mixing technology, and specifically relates to a laboratory water bath stirring and mixing device. Background Technology

[0002] Water baths are mainly used in laboratories for distillation, drying, concentration, and warm soaking of chemicals or biological products. They can also be used for constant temperature heating and other temperature tests. They are an essential tool for biology, genetics, virology, aquaculture, environmental protection, medicine, health, laboratories, analytical laboratories, education and scientific research.

[0003] Most existing water baths lack stirring and mixing devices, which increases manual labor. When stirring the materials in the container, the lack of clamping mechanism can easily cause the container to become unstable and shake, resulting in uneven heating due to the buoyancy of the water.

[0004] Therefore, improvements are urgently needed. Utility Model Content

[0005] To address the aforementioned deficiencies in the existing technology, this utility model provides a laboratory water bath stirring and mixing device, including a water bath, an adjusting support, a stirring mechanism, and a clamping mechanism. The water bath includes a body with a heating tank inside. The adjusting support includes a support rod, a crossbeam, and a bushing. The support rod is vertically fixed to the body, and the crossbeam is perpendicular to the support rod. Both the crossbeam and the support rod pass through the bushing. The bushing is provided with a first fixing bolt and a second fixing bolt. The first fixing bolt is used to position the vertical movement of the bushing on the support rod, and the second fixing bolt is used to position the horizontal movement of the crossbeam in the bushing.

[0006] The stirring mechanism is located above the heating tank. The stirring mechanism includes a stirring motor and a stirring rod. The stirring motor is fixed to the end of the crossbeam, the stirring rod is vertically set, the top of the stirring rod is connected to the output shaft of the stirring motor, and the bottom of the stirring rod is equipped with stirring blades.

[0007] The clamping mechanism includes two clamping components symmetrically arranged on the left and right sides of the heating tank. The two clamping components can clamp the material container symmetrically from left to right, making the clamping more secure. Each clamping component includes a clamping support column and a Z-shaped connecting rod. The clamping support column is vertically fixed to the main body. One end of the Z-shaped connecting rod horizontally passes through the clamping support column, and the other end of the Z-shaped connecting rod extends downward into the heating tank. The other end of the Z-shaped connecting rod is provided with a clamping claw. A third fixing bolt is also provided on the clamping support column, which is used to position the horizontal movement of the Z-shaped connecting rod in the clamping support column. The Z-shaped connecting rod is designed to be detachable, and the clamping claws on the Z-shaped connecting rod are available in various models. Since the material container may have various different diameter specifications, in order to further adapt to different specifications of material containers, the corresponding Z-shaped connecting rod can be replaced to adapt to them, thereby improving the applicability of this device.

[0008] Optionally, a support net, an electric heating ring, and a temperature sensor are provided at the bottom of the heating tank. A material container is placed on the support net, the electric heating ring is used to heat the heating medium in the heating tank, and the temperature sensor is used to detect the temperature of the heating medium.

[0009] Specifically, the main body is also equipped with a control panel and a power switch. The electric heating ring, stirring motor and temperature sensor are all electrically connected to the control panel, and the speed of the stirring motor and the water bath temperature can be adjusted through the control panel.

[0010] Optionally, the gripping claws are made of spring plates, the gripping claws are adapted to the shape of the material container, and the gripping claws are covered with an elastic protective sleeve.

[0011] Alternatively, the elastic protective case may be made of rubber or silicone.

[0012] Specifically, this material is soft and heat-resistant, which can prevent the grippers from damaging the material container.

[0013] Optionally, the inner side of the elastic protective cover is provided with anti-slip texture.

[0014] Specifically, it provides an anti-slip effect.

[0015] Optionally, the bottom of the main body is provided with support legs.

[0016] This invention also includes other components that enable the laboratory water bath stirring and mixing device to function properly, all of which are conventional technologies in the field. Furthermore, any devices or components not specified in this invention employ conventional technologies in the field, such as water baths, stirring motors, and temperature sensors. The water bath can utilize existing technology, such as the Huaxi Xinrui brand HH-1 constant temperature water bath.

[0017] The working principle of this utility model is as follows: a material container filled with material is placed on a support net, and the two Z-shaped connecting rods in the two clamping components are adjusted so that the two clamping claws can clamp the material container in the center. Then, the third fixing bolt is tightened to fix the Z-shaped connecting rods, thus completing the clamping and fixing of the material container. Then, a heating medium is added to the heating tank, and the position and height of the stirring mechanism are adjusted by adjusting the support components so that the stirring blades can be in a suitable position in the material container. Then, the heating medium is heated, and the material in the material container is stirred. Constant temperature heating is ensured by the detection of temperature sensors.

[0018] The beneficial effects of this utility model are that by using a stirring mechanism and an adjusting support, and by using CNC to adjust the stirring speed and water bath temperature, manual labor is saved and stirring efficiency is improved; the material container is clamped and fixed by a clamping mechanism to prevent instability of the material container caused by stirring, and also to prevent uneven heating caused by water buoyancy, thereby improving the heating effect.
