[0002] Silica dehydration refers to the process of removing water from silica. After dehydration, silica can be used to prepare optical instrument lenses and glasses, etc. It is widely used. When dehydrating silica, a condensation device is also required.

[0003] Among them, the more common silica dehydration adopts the mechanical mixing method, adding silica and polymer materials together into the polycondensation device, and using mechanical force to mix them so that they interact at the molecular level and finally form a colloid. This dehydration method is simple and easy, so it is widely used. However, after searching and combining the actual silica dehydration polycondensation experience, the common polycondensation devices on the market currently have poor internal stirring ability, a single stirring direction and a slow mixing speed, which is not convenient for improving the polycondensation dehydration efficiency, and is not convenient for the orderly and convenient transportation of materials. Therefore, it is urgent to improve the existing silica dehydration polycondensation device and provide a polycondensation device for silica dehydration. Utility Model Content

[0025] On the basis of the above structure, the material feeding assembly 5 includes a material feeding pipe 51, a material storage box 52, a support rod 53, a first motor 54 and a material feeding auger 55. The top end of the material feeding pipe 51 passes through the processing tank 1 and is fixedly connected to the processing tank 1. The material storage box 52 is fixedly installed on the side of the bottom end of the material feeding pipe 51 away from the processing tank 1. A support rod 53 is fixed to the outer wall of the side of the bottom end of the material feeding pipe 51 close to the processing tank 1, and the right end of the support rod 53 is fixedly connected to the outer wall of the processing tank 1. The first motor 54 is fixedly installed on the bottom of the material feeding pipe 51, and the output end of the first motor 54 is fixedly connected to the material feeding auger 55.

[0026] In this embodiment, the first motor 54 is used to control the rotation of the feeding auger 55, so that the materials in the storage box 52 can be transported to the inside of the processing tank 1 in an orderly and uniform manner, which is convenient for stirring.

[0027] On the basis of the above structure, the storage box 52 and the feed pipe 51 are internally connected. The feed pipe 51 is arranged in an inclined shape. A discharge port 56 is provided on the right outer wall of one end of the feed pipe 51 located in the processing tank 1 .

[0028] In this embodiment, the discharge port 56 opened on the top right wall of the material delivery pipe 51 is utilized to facilitate the delivery of the material into the processing tank 1 .

[0029] On the basis of the above structure, the stirring assembly 9 includes a stirring rod 91, a first bracket 92, a stirring shaft 93, a second bracket 94 and a gear 95.

[0030] On the basis of the above structure, the gear 95 is connected to the conical gear 10 by meshing connection, and the diameter length of the gear 95 is only half of the diameter length of the conical gear 10 .

[0031] In this embodiment, the second motor 6 is started to control the square rod 7 to drive the sleeve 8 and the stirring assembly 9 to rotate synchronously.

[0034] When the feeding assembly 5 is used for feeding, the second motor 6 can be started to control the square rod 7 to drive the sleeve 8 and the two groups of stirring assemblies 9 to rotate synchronously, so as to achieve preliminary stirring of the raw materials. The silica and the polymer material can be fully mixed and reacted by stirring to achieve dehydration and polycondensation of the silica. At the same time, the gear 95 meshing with the conical gear 10 can be used to make the stirring assembly 9 rotate synchronously with the square rod 7, and the left and right stirring rods 91 can be synchronously and rapidly rotated to achieve multi-directional stirring of the raw materials. The stirring is stronger and the stirring effect is better, which can effectively shorten the time required for the dehydration and polycondensation reaction of silica and improve the dehydration efficiency.

[0035] During the stirring process, the left and right electric telescopic rods 11 can be used to control the conical teeth 10 to drive the sleeve 8 and the stirring assembly 9 to be raised and lowered, so that the stirring height position can be quickly adjusted, which is convenient for efficient and powerful stirring of materials at different positions;

[0036] It should be noted that if Figure 4 As shown in , the square rod 7 and the sleeve 8 are connected by a snap-fitting sliding connection, so that the sleeve 8 can not only rotate synchronously with the square rod 7, but also control the sleeve 8 to rise and fall and slide outside the square rod 7.
