Description

Technical Field

[0001] This utility model relates to the field of sodium fluorosilicate processing, specifically to a feeding device for sodium fluorosilicate crystallization. Background Technology

[0002] Sodium fluorosilicate crystals are colorless or white hexagonal crystals formed under specific conditions. This substance is usually an odorless and tasteless crystalline powder with hygroscopic properties. Its crystal morphology is stable. Industrially, sodium fluorosilicate crystals are mainly obtained by recycling byproducts from the production of superphosphate or fluoride salts in aluminum plants. Its high melting point and high-temperature stability make it a basic raw material for preparing high-performance furnace and kiln refractory materials, which can significantly improve the wear resistance and service life of ceramic furnaces, mortar, and other materials. In addition, sodium fluorosilicate crystals are also widely used in metal smelting, mineral processing, water treatment, and the production of fluorochemical products. In the glass industry, it is used as a brightener and flux to enhance the whiteness, gloss, and corrosion resistance of products. In the agricultural field, it can be used as an insecticide and wood preservative, demonstrating its cross-industry versatility.

[0003] In the production of sodium fluorosilicate crystallization, a feeding device is required. A certain concentration of fluorosilicic acid solution and sodium salt solution need to be added to the crystallization tank in a stoichiometric ratio. However, the traditional feeding method for the crystallization tank is not convenient for intermittent feeding, which affects the purity of sodium fluorosilicate crystallization and has certain drawbacks. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a feeding device for sodium fluorosilicate crystallization.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A feeding device for sodium fluorosilicate crystallization includes a storage tank, an installation frame is provided at one end of the outer side of the storage tank, a stirring motor is installed at the top of the storage tank, a feeding pipe is installed at one end of the top of the storage tank, a discharge port is opened at one end of the bottom of the storage tank, a feeding assembly is provided at the bottom of the storage tank, a stirring assembly is installed at the top of the inner side of the storage tank, the feeding pipe is used to inject raw materials into the tank, and the stirred material is fed through the discharge port.

[0006] Furthermore, the feeding assembly includes a turntable rotatably connected and installed at the bottom of the storage tank. A through hole is provided at one end of the bottom of the turntable, and a discharge pipe is installed at the bottom of the turntable and on the through hole. The top of the turntable is tightly fitted with the bottom of the storage tank, and the through hole can coincide with the discharge port when the turntable rotates. When the two coincide, the raw material in the storage tank flows into the discharge pipe through the through hole to achieve intermittent feeding.

[0007] Furthermore, a drive motor is installed at the bottom of the storage tank away from the turntable, and a drive gear is installed on the output shaft of the drive motor. A rotating shaft is installed at the bottom of the storage tank near the turntable, and a driven gear is installed at one end of the bottom of the rotating shaft. The driven gear meshes with the drive gear, and the rotating shaft drives the turntable in the feeding assembly to rotate, thereby realizing the automated control of the feeding process.

[0008] Furthermore, a fixing plate is installed on the outer ring surface of the rotating shaft, and guide columns are symmetrically installed at both ends of the top of the fixing plate. Extrusion grooves are opened at the four outer edges of the turntable. When the fixing plate rotates, the guide columns can be connected to the inside of the extrusion grooves. A rotating frame is installed on the outer ring surface of the rotating shaft above the fixing plate. When the rotating frame rotates, its outer ends are in contact with the outside of the turntable. When the fixing plate and the rotating frame rotate, their outer ends are not in contact with the drive motor. When the rotating shaft rotates, the guide columns on the fixing plate periodically connect to the extrusion grooves of the turntable. The mechanical extrusion pushes the turntable to rotate intermittently. The contact between the rotating frame and the outside of the turntable helps to stabilize the rotation trajectory of the turntable and prevent deviation.

[0009] Furthermore, the stirring assembly includes a stirring rod installed on the top of the inner side of the storage tank. The output shaft of the stirring motor passes through the interior of the storage tank and is connected to the top of the stirring rod. Several stirring blades are installed on the outer ring surface of the stirring rod. The rotating stirring blades fully mix the raw materials in the storage tank, preventing the materials from stratifying or clumping due to standing.

[0010] Furthermore, support rods are symmetrically installed on both sides of the top end of the outer ring surface of the stirring rod. A scraper is installed on the end of the support rod away from the stirring rod. The outer side of the scraper is in close contact with the inner wall of the storage tank. When the stirring rod rotates, the support rod drives the scraper to slide along the inner wall of the storage tank, scraping off the residual material adhering to the tank wall in real time, preventing the accumulation of material from affecting the feeding accuracy or causing uneven local concentration.

[0011] The beneficial effects of this utility model are as follows: When the rotating shaft on the feeding assembly rotates, the guide column on the fixed plate periodically connects to the extrusion groove of the turntable. Through mechanical extrusion, the turntable is driven to rotate intermittently. The rotating frame is in close contact with the outside of the turntable, which can help stabilize the rotation trajectory of the turntable and avoid deviation. The turntable controls the relative position of the through hole and the discharge port by rotating. When the two coincide, the raw material in the storage tank flows into the discharge pipe through the through hole to achieve intermittent feeding. The stirring motor drives the stirring rod to rotate and drive the stirring blade to fully mix the raw material in the storage tank, preventing the material from stratifying or clumping due to standing. When the stirring rod rotates, the support rod drives the scraper to slide along the inner side wall of the storage tank, scraping off the residual material attached to the tank wall in real time, preventing the material accumulation from affecting the feeding accuracy or causing uneven local concentration. It is convenient to operate and has better practicality. Attached Figure Description

[0018] The storage tank 1 is fixed above the crystallization tank by the mounting bracket 2. The feeding pipe 4 is used to inject raw materials into the tank. The stirring motor 3 drives the stirring component 6 to mix the materials in the tank to prevent sedimentation or agglomeration. The feeding component 5 controls the opening and closing of the discharge port 101 to achieve intermittent feeding, ensuring that the raw materials enter the crystallization tank evenly.

The top of the turntable 7 is tightly fitted with the bottom of the storage tank 1, and the through hole 701 can coincide with the discharge port 101 when the turntable 7 rotates.

[0020] The turntable 7 controls the relative position of the through hole 701 and the discharge port 101 by rotating. When the two coincide, the raw material in the storage tank 1 flows into the discharge pipe 8 through the through hole 701 to achieve intermittent feeding. The turntable 7 is tightly attached to the bottom of the storage tank 1 to prevent material leakage and ensure feeding accuracy.

[0021] A drive motor 9 is installed at the bottom of the storage tank 1 away from the turntable 7. A drive gear 10 is installed on the output shaft of the drive motor 9. A rotating shaft 11 is installed at the bottom of the storage tank 1 near the turntable 7. A driven gear 12 is installed at the bottom end of the rotating shaft 11.

A rotating frame 15 is installed on the outer ring surface of the rotating shaft 11 and above the fixing plate 13. When the rotating frame 15 rotates, its outer ends are in contact with the outside of the turntable 7.

[0026] The stirring motor 3 drives the stirring rod 16 to rotate, which in turn drives the stirring blades 17 to fully mix the raw materials in the storage tank 1, preventing the materials from stratifying or clumping due to standing. The distribution of the stirring blades 17 can expand the stirring range and improve the mixing efficiency, ensuring the uniformity of the raw materials and providing stable conditions for the subsequent crystallization reaction.
