Description

Technical Field

[0001] The utility model relates to the technical field of aerogel preparation, in particular to a bio-based aerogel preparation device. Background Art

[0002] Bio-based aerogels are widely available, low-cost, and green and sustainable. They usually show better mechanical properties and structural diversity, avoiding the high brittleness defects of inorganic aerogels, while also solving the problems of organic aerogels' pollution and poor recyclability. The preparation of bio-based aerogels is an extremely innovative and challenging process. First, natural bio-based materials such as cellulose and chitosan are selected as raw materials. Then, these materials are formed into a gel state through a series of chemical or physical treatments. Then, the solvent in the gel is removed by using appropriate drying techniques, such as freeze drying or supercritical drying, while carefully maintaining its unique three-dimensional porous network structure. Throughout the preparation process, precise control of various parameters is crucial to ensure that the resulting bio-based aerogels have ideal properties, such as low density, high porosity, good mechanical strength, and excellent functionality. For example, bio-based aerogels are prepared from wood cellulose. After complex and sophisticated process treatment, aerogel products with broad application potential in environmental protection, biomedicine, and other fields can be obtained.

[0003] In the process of preparing aerogel, multiple raw materials such as lignocellulose need to be mixed and stirred using a magnetic stirrer. According to the "magnetic stirrer" proposed in application number CN202222165078.1, the magnetic stirrer does not require a large number of top screws, which saves the operation steps of tightening the top screws and makes it more convenient and labor-saving to fix the beaker.

[0004] However, the above-mentioned magnetic stirrer uses two curved plates to clamp the beaker. When preparing aerogels of different capacities, beakers of different sizes are required, and the curved plates cannot fix beakers of different sizes well. Therefore, in view of the above phenomenon, a bio-based aerogel preparation device is proposed to meet the needs of actual use. Utility Model Content

[0024] In this embodiment, a motor and a magnetic transmission device are provided inside the mounting base 1. When the motor is started, it drives the magnetic transmission device to generate a rotating magnetic field. The stirrer 7 is usually made of magnetic material. Under the action of the rotating magnetic field, the stirrer 7 will be driven by the magnetic force and rotate accordingly.

[0031] Arc plates 92 are integrally formed on both sides of the mounting plate 91 , and arc guide bars 93 are integrally formed on the inner wall of the arc plates 92 .

There are a plurality of first side holes 83, and the plurality of first side holes 83 are evenly arrayed on the side of the mounting pole 81.

[0034] In this embodiment, by fitting the first side hole 83 with the second side hole 841 , inserting the cylindrical sleeve 842 and fixing it with the bolt 84 , the height of the cross beam 85 can be adjusted, and then the contact position between the rotating block 95 and the beaker 100 can be adjusted, so that beakers 100 of different heights can be adapted for use.

[0035] Working principle: A motor and a magnetic transmission device are arranged inside the mounting base 1. When the motor is started, the magnetic transmission device is driven to generate a rotating magnetic field. The stirring bar 7 is usually made of a magnetic material.
