Description

A novel PTA oxidation residue recovery device Technical Field

[0001] This utility model belongs to the field of PTA oxidation residue recovery technology, specifically a novel PTA oxidation residue recovery device. Background Technology

[0002] During the PTA production process, oxidation residues are inevitably generated. If the heavy metals contained in these residues are directly buried or incinerated for recycling, it will cause serious environmental pollution. Therefore, recycling equipment is needed to treat the residues.

After the PTA oxidation residue is treated with sodium carbonate solution for sedimentation, the mixture is separated into solid and liquid components, thereby improving the recovery efficiency.

[0034] Working principle: During operation, the first tooth 18, rotating shaft 19, second tooth 110, elastic connecting plate 111, and abutment 112 cooperate to ensure that the rotating column 15 can only rotate clockwise. After the operator injects the residue and solution into the inside of the recovery sedimentation tank 1 through the feed pipe 11 and solution injection pipe 12, the output motor 13 is started. The output motor 13 drives the rotating column 15 to rotate clockwise. The rotating column 15, through the mixing plate 16, mixes the solid-liquid mixture inside the recovery sedimentation tank 1, thereby improving the mixing effect of the solid-liquid mixture. After the solid-liquid mixture has settled at the bottom inside the recovery sedimentation tank 1, the output motor 13 is started. The output motor 13 rotates counterclockwise through the rotating column 15, thereby causing the connecting rod 17 to rotate. The moving connecting rod 17 can drive the cleaning baffle 113 to scrape the sediment at the bottom of the recovery sedimentation tank 1 towards the inside of the discharge valve 14. When the cleaning baffle 113 is at the top of the discharge valve 14, the discharge valve 14 is opened.

When the connecting rod 17 is not driven, the reset spring assembly 114 can drive the entire device to reset. During operation, when the cleaning baffle 113 rotates, it can drive the transmission gear ring 25 to rotate, thereby causing the second gear 24 to rotate as well. The first baffle 2 is driven to move upward by the first gear 23, rack 22 and limiting connecting plate 21; when the cleaning baffle 113 moves to the top of the discharge valve 14, the side wall of the first baffle 2 can fit against the side wall of the cleaning baffle 113, thereby sealing the internal space of the cleaning baffle 113; the overall device reduces the occurrence of liquid entering the inside of the discharge valve 14 from the other side of the cleaning baffle 113; the overall device reduces the occurrence of a large amount of liquid being discharged along with solid matter; and improves work efficiency; during operation, the bottom of the cleaning plate 32 is made of elastic material; multiple sets of spring columns 31 can drive the cleaning plate 32 to move downward through the slide groove 3, so that the bottom end of the cleaning plate 32 fits more closely with the bottom of the recovery sedimentation tank 1; and the cleaning baffle 113 rotates During operation, the cleaning plate 32 can scrape away the sediment at the bottom of the inner side of the recycling sedimentation tank 1, thereby improving the cleaning efficiency of the cleaning baffle 113. When working, the first magnetic plate 4 and the second magnetic plate 41 repel each other due to magnetic force, which makes the bottom of the cleaning plate 32 fit more closely to the bottom of the inner side of the recycling sedimentation tank 1, thereby improving the stability of the cleaning plate 32 when pushing the sediment at the bottom of the inner side of the recycling sedimentation tank 1 and reducing the occurrence of sediment adhering to the bottom of the inner side of the recycling sedimentation tank 1.
