Description

Technical Field

[0001] The invention relates to the technical field of aerogel preparation, in particular to an aerogel preparation device for battery thermal insulation. Background Art

[0002] Aerogel refers to a nano-scale porous solid material formed by using a sol-gel method to replace the liquid phase in the gel with gas in a certain drying method. It can be used for battery insulation to ensure the service life and quality of the battery. When producing and processing aerogel, it needs to go through sol-gel, drying and injection molding operations.

[0003] The existing Chinese patent application with publication number CN115504272A discloses a sol preparation device for carbon aerogel production, including a stirring tank, a stirring mechanism is arranged in the stirring tank, a conveyor belt is arranged below the stirring tank, a box is placed on the conveyor belt, a plurality of receiving boxes are arranged in the box, a liquid outlet pipe is arranged at the bottom of the stirring tank, a solenoid valve is arranged on the liquid outlet pipe, a distribution pipe is horizontally arranged at the bottom end of the liquid outlet pipe, the length direction of the distribution pipe is consistent with the width direction of the conveyor belt, a plurality of shunt pipes are distributed on the distribution pipe along its own length direction, and the number of the distribution pipes is consistent with the number of columns of the receiving boxes distributed along the width direction of the conveyor belt; the invention can conveniently distribute the stirred sol to a plurality of receiving boxes, and can ensure that the amount of sol in each receiving box is consistent.

[0004] However, the aerogel preparation device has the following defects when used:

[0005] 1. When the existing aerogel preparation device is producing and preparing aerogel, in order to ensure the efficiency of aerogel in the sol-gel process, it is generally necessary to stir and mix the aerogel material being prepared. However, during the preparation, the traditional solution requires stirring the aerogel material after the sol-gel is completed to improve the efficiency of cooling and drying. At this time, multiple sets of driving parts and stirring structures are required to perform sol-gel and cooling and drying of the aerogel separately, resulting in a high cost of the aerogel preparation device. However, using one set of driving parts to operate the sol-gel and cooling and drying operations makes it difficult to control the stirring time of the sol-gel and cooling and drying separately, and the quality of the aerogel is easily affected by the excessive stirring time (sol-gel);

[0006] 2. When preparing and producing aerogel, the existing device generally uses stirring to improve the activity of various materials in the aerogel in order to improve the efficiency of the aerogel in the sol-gel process. However, the traditional solution has a poor stirring effect when stirring the aerogel material, so it takes a longer time for the sol-gel operation, and the efficiency of aerogel preparation is low.

At the same time, when the aerogel is stirred in the sol-gel process, the connection with the rotating shaft can be timely disconnected after the stirring time is guaranteed, ensuring that when the cooled and dried aerogel is stirred, the sol-gel aerogel will not be stirred, thereby avoiding the problem of forming large particles of aerogel in the sol-gel process due to a long stirring time and affecting the structure and performance of the aerogel;

[0046] 2. In the aerogel preparation device used for battery insulation, when the aerogel is subjected to sol-gel, the rotation of the slave shaft can drive the stirring blades installed on the outside to rotate, so as to stir the aerogel material inside the gel box. When the slave shaft rotates, it will also drive the stirring blades installed on the outside of the sleeve to rotate (in the opposite direction of the rotation of the stirring blades on the outside of the slave shaft). At this time, multiple groups of stirring operations with opposite rotation directions can be used to enhance the activity of the aerogel material and accelerate the effect of the aerogel sol-gel. And when the slave shaft rotates, it will also drive the longitudinal blades to rotate, so as to facilitate the movement and tumbling of the aerogel at the bottom to the middle, thereby maximizing the efficiency of the aerogel sol-gel.

[0047] 3. In the aerogel preparation device used for battery insulation, when cooling and drying the aerogel, the central shaft will drive the multiple sets of mixing blades on its outer side to rotate when rotating, stirring the aerogel inside the drying box, ensuring that the aerogel at each position of the drying box can fully contact the cooling rod, thereby improving the efficiency of cooling and drying the aerogel.

[0048] 4. In the aerogel preparation device for battery insulation, after the aerogel completes the sol-gel and cooling and drying, the aerogel can be automatically transferred to the inside of the lower mold base through the discharge nozzle and stored inside the lower mold base. When the conveyor belt is in operation, it will automatically and evenly drive the lower mold base and aerogel on the top of the conveyor belt for transportation and transmission operations, making it convenient for the aerogel to be moved to the lower group of equipment for injection molding and other operations, thereby improving the efficiency of aerogel preparation.
