Description

Technical Field

[0001] The utility model relates to the technical field of ammonium bifluoride production equipment, in particular to an ammonium bifluoride self-separation device. Background Art

[0002] Ammonium bifluoride is a white or colorless, transparent, orthorhombic crystal that is easily deliquescent and agglomerated in air but readily soluble in water. It is primarily used as a glass etchant, preservative, and solvent for the production of metallic beryllium from beryllium oxide. During its production, a separation device is required to separate the ammonium bifluoride crystals from the mother liquor.

[0003] After searching, the Chinese patent publication number CN207238271U discloses a solid-liquid separator specifically for ammonium bifluoride production, including a separation tank, a motor, a rotating shaft, an impeller, a separation net, a centrifugal layer, a liquid layer, a transverse pusher, an inclined pusher, a feeder, a high-frequency vibrator, a liquid collector, an insulation layer and a pressurizer.

[0004] This patent sets up an inclined pusher and a horizontal pusher. When the solid-liquid separation of the material is completed, the inclined pusher pushes up the left side of the separation tank through the second push plate, causing the separation tank to tilt, which is conducive to the discharge of the separated solids and liquids. The horizontal pusher pushes out the solid material remaining in the centrifugal layer through the first push plate, making the separator convenient and efficient in discharging. However, the separation operation needs to be stopped every time the solid material is discharged, which reduces production efficiency. Utility Model Content

[0030] During production, the mixture of mother liquor and crystals is fed into the combination of feed cylinder 3, centrifugal cylinder 4 and discharge cylinder 6 through feed hopper 5. Motor 9 drives driving gear 10 to rotate, and the centrifugal cylinder 4 is rotated through the transmission of driving gear 10 and driven gear 11. The centrifugal force generated by the rotation of centrifugal cylinder 4 separates the mother liquor from the crystals. The mother liquor passes through centrifugal cylinder 4 and flows out through liquid discharge pipe 13. The separated crystals move toward discharge cylinder 6 through relative rotation of centrifugal cylinder 4 and screw shaft 7, and flow out through solid discharge pipe 14.

[0031] By providing the feed cylinder 3, the centrifugal cylinder 4, the feed hopper 5 and the discharge cylinder 6, continuous separation of the mother liquor and the crystals is achieved, thereby improving production efficiency.

[0032] Example 2

The inner wall of the driven bevel gear 15 is connected to a spiral blade 16 through a connecting rod, and the spiral blade 16 is located inside the solid discharge pipe 14.

[0034] When the motor 9 rotates, the driving bevel gear 17 is driven to rotate through the transmission shaft 18, and the spiral blade 16 is driven by the transmission of the driving bevel gear 17 and the driven bevel gear 15 to rotate and transport the crystals entering the solid discharge pipe 14 outward to prevent the crystals from gathering and clogging in the solid discharge pipe 14.

[0035] By providing the spiral blades 16 , the crystals entering the solid discharge pipe 14 are transported outwards during crystal discharge, thereby preventing the crystals from accumulating and clogging in the solid discharge pipe 14 .

[0037] Working principle: During production, the mixture of mother liquor and crystals is input into the combination of feed cylinder 3, centrifugal cylinder 4 and discharge cylinder 6 through feed hopper 5, and motor 9 drives driving gear 10 to rotate. The centrifugal cylinder 4 is rotated by the transmission of driving gear 10 and driven gear 11. The centrifugal force generated by the rotation of centrifugal cylinder 4 separates the mother liquor from the crystals. The mother liquor passes through the centrifugal cylinder 4 and flows out through the liquid discharge pipe 13. The separated crystals move toward the discharge cylinder 6 through the relative rotation of centrifugal cylinder 4 and spiral shaft 7, and flow out through the solid discharge pipe 14. At the same time, the transmission shaft 18 drives the driving bevel gear 17 to rotate, and the spiral blade 16 is driven by the transmission of driving bevel gear 17 and driven bevel gear 15 to rotate to transport the crystals entering the solid discharge pipe 14 outward to avoid crystal accumulation and blockage in the solid discharge pipe 14.
