DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example: like Figure 1-16 As shown, this embodiment proposes a centrifugal separation device for removing sulfate from brine, including a horizontal centrifuge 10, wherein the horizontal centrifuge 10 is provided with a frame 12, a drum separation assembly 11 is provided on the frame 12, a cover plate 13 is also provided on the frame 12, and a liquid discharge port 15 and a material discharge port 14 are provided on the frame 12; The frame 12 is provided with a frame discharge cavity 121, and the discharge port 14 is connected to the frame discharge cavity 121. The cover plate 13 is provided with a cover plate discharge cavity 132. The frame discharge cavity 121 and the cover plate discharge cavity 132 are matched in position. A driving gear 42 is provided in the cover plate discharge cavity 132. A scraper assembly 20 is also provided on the cover plate discharge cavity 132. The driving gear 42 cooperates with the scraper assembly 20, so that the scraper assembly 20 reciprocates in a circular motion to introduce the solid phase material into the discharge port 14.

[0020] In this case, the horizontal centrifuge 10 and the drum separation assembly 11 are prior art and will not be described in detail here; In this embodiment, when removing sulfate radicals from brine, the brine is frozen so that sodium sulfate is precipitated in large quantities in the form of hydrates, and then connected to a horizontal centrifuge 10 through a pipeline. After separation in the horizontal centrifuge 10, due to the different densities of solid particles and liquid, the centrifugal force causes the solid particles to be pushed to the drum wall of the drum separation assembly 11, while the liquid remains in the central area, thereby achieving separation of solid and liquid, separating the crystallized sodium sulfate from the brine, and removing the sulfate radical in the form of crystals; During the separation process, as the drum separation assembly 11 is continuously rotating, the crystallized sodium sulfate, i.e., the solid phase material, will be dispersed in the frame discharge cavity 121 and the cover plate discharge cavity 132. At this time, the driving gear 42 rotates, driving the scraper assembly 20 to perform a reciprocating circular motion, which can drive the solid phase material to move toward the discharge port 14. The scraper assembly 20 with the reciprocating circular motion can realize the continuous discharge of the solid phase material, thereby ensuring the continuity and high efficiency of the centrifugal separation process. Moreover, the movement of the scraper assembly 20 prevents the accumulation of the solid phase material on the drum wall, thus avoiding affecting the normal discharge process and ensuring the cleanliness of the interior of the horizontal centrifuge 10. At the same time, the reciprocating motion of the scraper assembly 20 helps to evenly push the solid material to the discharge port 14, thereby stabilizing the flow rate of the discharged material and facilitating subsequent processing or collection.

[0021] Specifically, a frame limiting shell 30 is provided on the frame discharging cavity 121, and a cover plate limiting shell 40 is provided on the cover plate discharging cavity 132.

[0023] In this embodiment, a stable circular cavity can be formed by the frame limiting shell 30 and the cover plate limiting shell 40. When the solid phase material is thrown out by the drum separation component 11, the solid phase material can be blocked so that the solid phase material is placed in a circular space, so that when the scraper component 20 reciprocates in a circular motion in the later stage, it is convenient to guide the solid phase material to move to the discharge port 14.

The two groups of guide rods 45 are arranged on both sides of the driving gear 42 .

[0027] In this embodiment, when the solid phase material is scraped, the driving gear 42 rotates back and forth, and through the cooperation between the driving gear 42 and the driving internal rack 26, the arc plate 21 reciprocates around the axis of the arc plate 21, thereby driving the first scraper plate 22 and the second scraper plate 23 to move, and the solid phase material is scraped, ensuring the stable discharge of the solid phase material.

[0028] Specifically, the arc length of the second scraper plate 23 is greater than the arc length of the shell discharge port 32; The second scraper plate 23 is provided with a sealing rubber frame 24 . The sealing rubber frame 24 is fixedly connected to the second scraper plate 23 . The sealing rubber frame 24 is arranged toward the arc surface 41 of the cover plate.
