Abstract
Description
Technical Field
[0001] This utility model relates to the field of silica drying technology, specifically a novel silica spray drying device. Background Technology
[0002] The industrial production of silica mainly adopts the precipitation method. The main production process involves preparing industrial water glass from silica, then precipitating the initial silica product with strong acid, followed by filtration, spraying, drying, and pulverizing to finally obtain the finished silica product.
[0003] Currently, most existing silica drying processes involve introducing the slurry into a container and spraying mist through nozzles to react with the slurry for drying. This method limits the contact area between the slurry and the mist, which can lead to uneven contact between the flue gas and the slurry when dealing with large quantities of slurry, resulting in particle agglomeration and affecting the quality of the final product. Utility Model Content

[0005] More preferably, support legs are fixedly installed at the four corners of the lower end of the drying chamber, a collection plate is fixedly installed at the lower end of the drying chamber, and limit grooves are provided at the four corners of the upper end of the drying chamber.
[0006] More preferably, a first reserved hole is provided at the side end of the drying chamber, an air intake is slidably installed at the side end of the first reserved hole, and a second reserved hole is provided at the side end of the drying chamber.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] In this invention, silica slurry is guided into the device by a guide pipe. Then, a drive motor drives a rotating column to rotate, which in turn drives the guide plate and the outer flow plate to rotate. With the help of the first and second baffle plates, the slurry is scattered in the drying chamber and reacts with the flue gas introduced by the air inlet to form water vapor and solids. This increases the contact area between the slurry and the flue gas during use, thereby improving the reaction uniformity, reducing particle agglomeration, and improving the quality of the finished product.

[0026] In this embodiment, as Figure 1 and Figure 4 As shown, the outflow plate 35 is sleeved on the outer surface of the rotating column 3 by the limiting buckle plate 32. The upper end of the outflow plate 35 is fixedly installed with a second baffle plate 37 and a first baffle plate 36. The guide plate 33 is rotatably installed with an installation collar 34, which is sleeved on the outer surface of the rotating column 3. This structure allows the slurry to flow from the opening in the guide plate 33 to the top of the outflow plate 35. With the help of the first baffle plate 36 and the second baffle plate 37, the slurry is separated and then thrown into the drying chamber 14 by centrifugal force.
[0027] The usage and advantages of this utility model: The working process of this new type of precipitated silica spray drying device is as follows:
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when using the device, the user first places it on the water surface. The user then picks up the drying chamber 1 and installs support legs 11 at the four corners below the drying chamber 1. A collection plate 12 is installed below the drying chamber 1, and an air intake 16 is installed in the first pre-drilled hole 15 on the side of the drying chamber 1. Next, the user picks up the top plate 2 and installs upper limit posts 21 at the four corners below the top plate 2. Fixed handles 22 are installed on both sides above the top plate 2. A bracket 23 is installed above the top plate 2, and an mounting plate 24 is installed inside the bracket 23. A guide pipe 25 is installed on the side of the mounting plate 24. Finally, the assembled top plate is... Plate 2 is fitted with the limiting groove 13 opened above the drying chamber 1 along the limiting post 21 to install the top plate 2 on the top of the drying chamber 1. Then, the rotating post 3 is lifted, and the drive motor 31 is installed on the top of the rotating post 3. The upper limit plate 32 is installed below the rotating post 3. The outer flow plate 35 is fitted on the outer surface of the rotating post 3. The upper limit plate 32 is installed below the rotating post 3 to limit the outer flow plate 35. The first baffle plate 36 and the second baffle plate 37 are installed above the outer flow plate 35. Then, the guide plate 33 is lifted, and the installation collar 34 is installed inside the guide plate 33. Finally, the guide plate 33 is installed on the outer flow plate 3. Above 5, pick up the assembled rotating column 3 and install it in the opening inside the mounting plate 24. Then, install the guide plate 33, the outer flow plate 35, and other parts inside the drying chamber 1. When the user needs to use the device, the user starts the air intake 16, which continuously inputs flue gas into the drying chamber 14 inside the drying chamber 1. Then, the flue gas is connected to the pipe along the guide pipe 25, and the silica slurry is injected into the guide plate 33 along the pipe and the guide pipe 25. Then, the drive motor 31 is started, which drives the rotating column 3 to rotate, thereby driving the outer flow plate 35, the guide plate 33, and other parts to rotate. When the guide plate 33 rotates, the slurry will pass through the bottom hole of the guide plate 33 and come to the top of the outer flow plate 35. Under the centrifugal force and the obstruction of the first baffle plate 36 and the second baffle plate 37, the slurry gradually slides to the outside and then flies out between the outer flow plate 35 and the guide plate 33 and disperses in the drying chamber 14. When it disperses in the drying chamber 14, it will react with the flue gas injected into the drying chamber 14 and mix with the flue gas to form solids and water vapor. Then, an air pump is installed in the second reserved hole 17 opened on the side of the drying box 1 to extract the water vapor. The solids fall into the collection plate 12 for collection and obtain the white carbon black product.
