Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges for magnesium sulfate production, in particular to a centrifuge for magnesium sulfate production. Background Art

[0002] The centrifuge used in magnesium sulfate production usually consists of a cylindrical centrifugal chamber with a rotating centrifugal rotor inside. The centrifugal chamber and the centrifugal rotor are usually made of materials with good corrosion resistance, such as stainless steel. The centrifuge generates centrifugal force by rotating the centrifugal rotor at high speed, and uses the centrifugal force to separate solid particles from liquid. In magnesium sulfate production, the centrifuge is usually used to separate the crystal particles in the magnesium sulfate solution from the solution.

[0003] At present, the commonly used centrifugal methods in magnesium sulfate production include centrifugal filtration. Centrifugal filtration can quickly and efficiently separate solid particles from liquids and improve product purity. Centrifugal filtration can select appropriate filter media according to needs and is suitable for separating solid particles of different particle sizes. Centrifugal filtration operation is relatively simple and easy to control and maintain.

[0004] However, simply using centrifugal filtration will result in low separation efficiency because it only uses centrifugal force to separate the particles. Low separation efficiency will extend the separation process time and require more processing steps or repeated operations. This will increase the production cycle and reduce production efficiency. At the same time, due to low separation efficiency, more solvents or reprocessing steps may be required to improve product purity, increasing resource waste. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a centrifuge for magnesium sulfate production, aiming to improve the existing centrifugal filtration method. Separating it only by centrifugal force will lead to the problem of low separation efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a centrifuge for producing magnesium sulfate, comprising a centrifugal bucket, a top cover fixedly connected to the top of the centrifugal bucket, a motor 1 fixedly connected to one side of the top of the top cover, a gear fixedly connected to the output end of the motor 1, a rotating ring rotatably connected to the centrifugal bucket and the inside of the top cover, a rotating column fixedly connected to the top of the rotating ring, an outer wall of the rotating column rotatably connected to the centrifugal bucket and one side of the inside of the top cover, a rack fixedly connected to the outer wall of the rotating column on one side, the gear meshes with the rack, a grid fixedly connected between the rotating rings on both sides, a discharge pipe fixedly connected to one side of the outer wall of the rotating column on the other side, a valve fixedly connected to one end of the discharge pipe, a motor 2 fixedly connected to the inside of the rotating column on one side, a stirring rod fixedly connected to the output end of the motor 2, and a connecting component is provided on the outer wall of the centrifugal bucket.

[0007] Furthermore, the connecting assembly includes flange 1 and flange 2, wherein the interior of flange 1 is fixedly connected to the outer wall of the top cover, and the interior of flange 2 is fixedly connected to the outer wall of the centrifugal barrel.

[0008] Furthermore, a ring-shaped array of fixed columns is fixedly connected to one side of the outer wall of the rotating ring, and the outer wall of the fixed column is slidably connected to the inside of the grid.

[0009] Furthermore, a wedge-shaped slide bar 1 is slidably connected inside the rotating ring, and an outer wall of the wedge-shaped slide bar 1 is slidably connected inside the fixed column.

[0010] Furthermore, a wedge-shaped sliding rod 2 is slidably connected inside the rotating ring, and a limiting groove is provided on one side inside the wedge-shaped sliding rod 1.

[0011] Furthermore, one side of the wedge-shaped sliding rod is rotatably connected with a threaded column, and the outer wall of the threaded column is threadedly connected to the inside of the rotating ring.

[0012] Furthermore, a limiting groove is provided inside the wedge-shaped sliding rod, and rotating clamps are rotatably connected to both sides of the fixing column.

[0013] Furthermore, a spring is arranged inside the fixed column, one end of the spring is fixedly connected to one end of the wedge-shaped sliding rod, and the other end of the spring is fixedly connected to the inner wall of the fixed column.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Specifically, magnesium sulfate solution is injected into the center of the rotating column 5 on the top of the top cover 2, and the solution will flow into the grid 11. Next, the gear 4 is driven to rotate by the motor 13, and the gear 4 engages with the rack 6 on the rotating column 5 to rotate the rotating column 5. In this way, the rotating ring 10 fixed at the bottom of the rotating column 5 will drive the grid 11 to rotate. Through the rotation of the grid 11, the solid particles in the magnesium sulfate solution will be affected by the centrifugal force and precipitate to the outside of the grid 11, while the clean solution remains in the inside of the grid 11. At the same time, the stirring rod 14 can be driven by the motor 2 13 to rotate and stir inside the grid 11. This stirring operation can accelerate the precipitation rate of the solid particles in the solution and ensure that they are evenly distributed in the grid 11. Through the combined action of this centrifugal treatment and stirring, the solid particles in the magnesium sulfate solution can be more effectively separated and precipitated, thereby improving the separation efficiency and product purity.

[0029] Specifically, when the grid 11 needs to be fixed on the rotating ring 10, the fixing column 19 can be used and inserted into the interior of the grid 11. Then, by rotating the threaded column 15, the wedge-shaped slide bar 21 is pushed to slide toward the inner side of the rotating ring 10. When the wedge-shaped slide bar 21 slides, it will push out the wedge-shaped slide bar 16. The limiting groove 18 inside the wedge-shaped slide bar 16 will abut against one side of the rotating clamp 17 and push it, so that the rotating clamp 17 rotates and presses against the inner wall of the grid 11, ensuring the stability and accuracy of the grid 11 during the centrifugation process.

[0030] Working principle: During centrifugation, magnesium sulfate can be injected from the center of the rotating column 5 on the top of the top cover 2, and the magnesium sulfate will flow into the grid 11, and then the gear 4 can be driven to rotate by the motor 13, and the gear 4 can drive the rotating column 5 to rotate through the rack 6 on the rotating column 5, and the rotating ring 10 fixed at the bottom of the rotating column 5 will drive the grid 11 to rotate, so that the magnesium sulfate is centrifuged by the grid 11. At the same time, the stirring rod 14 can be driven by the motor 2 13 to rotate inside the grid 11, so that the sulfur inside the grid 11 can be stirred. When the grid 11 is fixed on the rotating ring 10, the fixing column 19 on the rotating ring 10 can be inserted into the grid 11, and then the wedge-shaped slide bar 21 is pushed to slide inwardly of the rotating ring 10 by rotating the threaded column 15, and the wedge-shaped slide bar 21 will push out the wedge-shaped slide bar 16, and the limiting groove 18 inside the wedge-shaped slide bar 16 will abut against one side of the rotating clamp 17 and push it, so that the rotating clamp 17 is rotated and pressed against the inner wall of the grid 11, and the grid 11 can be fixed on the rotating ring 10.
