Description

Technical Field

[0001] This utility model relates to the field of nano-silica technology, and in particular to a drying device for the production of nano-silica. Background Technology

[0002] Nanomaterials refer to materials with at least one dimension in the nanometer size range (1–100 nanometers) in three-dimensional space. Nanomaterials exhibit small size effects, surface effects, and macroscopic quantum tunneling effects, thus displaying many unique properties and showing broad application prospects in catalysis, light filtering, light absorption, medicine, magnetic media, and new materials. Nano-silicon dioxide (SDI) is an inorganic chemical material, commonly known as white carbon black. Due to its ultrafine nanoscale size (1–100 nm), it possesses many unique properties, such as optical properties that resist ultraviolet radiation and the ability to improve the anti-aging, strength, and chemical resistance of other materials. Its applications are very wide-ranging. Nano-silicon dioxide is an amorphous white powder, non-toxic, odorless, and pollution-free. Its microstructure is spherical, exhibiting flocculent and network-like quasi-granular structures. Its molecular and structural formula is SiO2, and it is insoluble in water. Nano-silicon dioxide requires drying during its production process.

[0003] Currently, there are various drying devices for the production of nano-silica on the market, but they generally suffer from poor drying effects. When drying nano-silica, the drying speed is faster at the end of the nano-silica closer to the heating end, while the drying speed is slower at the side farther from the heating end. Since the nano-silica is mostly in a static state after being put in, and the contact area between the silicon dioxide raw material and the heating part is small in the silicon dioxide heating and drying devices on the market.

[0004] Therefore, it is necessary to provide a drying device for the production of nano-silica to solve the above-mentioned technical problems. Utility Model Content

[0014] 1. This utility model uses the rotation of the placement plate to drive the nano-silica to be dried to rotate synchronously. Before rotation, the height of the adjustment plate can be set according to the amount of nano-silica. When rotating, the nano-silica to be dried passes through the bottom of the adjustment plate, thereby flattening the nano-silica.

[0016] 3. By setting a connecting ring and a connecting groove, this utility model improves the stability of the connection between the cover plate and the drying cylinder on the one hand, and also protects the connecting groove through the connecting ring, thereby improving the sealing of the connection between the cover plate and the drying cylinder.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] refer to Figures 1 to 5 This utility model provides a drying device for the production of nano-silica, comprising: a drying cylinder 1 with an open top, a cover plate 5 movably connected to the top of the drying cylinder 1, an electric heater 20 installed at the bottom of the cover plate 5, an adjusting slide rail 16 installed at the bottom of the drying cylinder 1 on one side of the electric heater 20, the adjusting slide rail 16 being connected to the side of an adjusting plate 17 via a slider, a placement plate 2 installed inside the drying cylinder 1, the bottom of the placement plate 2 being connected to the drive end of a rotary motor 15, the rotary motor 15 being installed inside the drying cylinder 1 below the placement plate 2, and a protective ring 3 connected to the top edge of the placement plate 2.

[0025] It should be noted that by setting a rotary motor 15, the placement plate 2 can be rotated. During use, the nano-silica to be dried can be placed into the drying cylinder 1. The rotation of the placement plate 2 causes the nano-silica to rotate synchronously. Before rotation, the height of the adjusting plate 17 can be set according to the amount of nano-silica. The nano-silica to be dried passes through the bottom of the adjusting plate 17 during rotation, thus flattening the nano-silica and effectively increasing its surface area and reducing its density. The thickness is increased to improve drying efficiency. Driven by the rotary motor 15, the flattened nano-silica is driven to pass sequentially under the electric heater 20. The electric heater 20 can dry all parts of the flattened nano-silica, improving the drying efficiency. Furthermore, the adjusting plate 17 is connected to the adjusting slide rail 16. During the drying process, the height of the adjusting plate 17 can be continuously lowered to flatten the top of the dried nano-silica, exposing the nano-silica below, and then drying the nano-silica below, effectively improving the drying efficiency.

[0026] In the embodiments of this utility model, reference is made to Figure 3 As shown, the peripheral side of the placement plate 2 is rotatably connected to the guide groove, which is circular in shape and is located on the inner surface of the drying cylinder 1.

[0027] It should be noted that by setting guide grooves, the stability of the rotation of the placement plate 2 can be effectively improved when the placement plate 2 is rotated under the drive of the rotary motor 15.

[0028] In the embodiments of this utility model, reference is made to Figure 1 As shown, the top of the cover plate 5 is connected to the bottom of the movable plate 6, the movable plate 6 is connected to the movable slide rail 7 via a slider, and the bottom of the movable slide rail 7 is connected to the support base 8.

[0029] It should be noted that by setting the movable slide rail 7, the cover plate 5 can be automatically moved up and down by the drive of the movable slide rail 7, so as to realize the full automation of the movement of the cover plate 5.

[0030] In the embodiments of this utility model, reference is made to Figure 2 As shown, the bottom of the cover plate 5 is provided with a connecting ring 9, and the top of the drying cylinder 1 is provided with a connecting groove 4 that cooperates with the connecting ring 9.

[0031] It should be noted that by setting the connecting ring 9 and the connecting groove 4, on the one hand, the stability of the connection between the cover plate 5 and the drying cylinder 1 is improved, and on the other hand, the connecting ring 9 can also protect the connecting groove 4 and improve the sealing of the connection between the cover plate 5 and the drying cylinder 1.

[0032] In the embodiments of this utility model, reference is made to Figure 5 As shown, the top of the adjusting plate 17 is connected to an L-shaped limiting plate 18, and the side of the horizontal part of the limiting plate 18 is slidably connected to a limiting groove 14, which is provided on the inner side of the drying cylinder 1.

[0033] It should be noted that by setting the limit plate 18, the stability of the adjusting plate 17 when moving up and down can be improved by the guide limit of the limit groove 14.

[0034] In the embodiments of this utility model, reference is made to Figure 5 As shown, a baffle 19 is installed on the side of the slider on one side of the adjustment plate 17, and the bottom height of the baffle 19 is the same as the bottom height of the adjustment plate 17.

[0035] It should be noted that by setting up the baffle 19, the nano-silica to be dried can be spread out a second time, preventing some nano-silica from not being spread out by the adjusting plate 17, which would affect the drying efficiency.

[0036] In the embodiments of this utility model, reference is made to Figure 2 As shown, the top of the cover plate 5 is connected to a guide block 10, the top of the guide block 10 is provided with a guide hole 11, the guide hole 11 is slidably connected to a guide shaft 12, and the bottom of the guide shaft 12 is connected to the top of the second support base 13.

[0037] It should be noted that by setting the guide block 10 to drive the guide block 10, the stability of the cover plate 5 moving up and down can be improved by limiting the guide shaft 12.

[0038] The working principle of the drying device for the production of nano-silica provided by this utility model is as follows:

[0039] Before rotation, the height of the adjusting plate 17 can be set according to the amount of nano-silica. When the nano-silica to be dried rotates, it passes through the bottom of the adjusting plate 17, thus flattening the nano-silica. This can effectively increase the area of ​​the nano-silica and reduce its thickness, improving drying efficiency. Driven by the rotary motor 15, the flattened nano-silica passes sequentially under the electric heater 20. The electric heater 20 can dry all parts of the flattened nano-silica, improving drying efficiency. Furthermore, by connecting the adjusting plate 17 to the adjusting slide rail 16, the height of the adjusting plate 17 can be continuously lowered during the drying process. This flattens the top of the dried nano-silica, exposing the nano-silica at the bottom, thus drying the nano-silica at the bottom and effectively improving drying efficiency.

[0040] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0041] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
