Description

Technical Field

[0001] This utility model relates to the field of phosphoric acid production equipment, and in particular to a filtration device for phosphoric acid purification. Background Technology

[0002] Ensuring the purity of phosphoric acid is crucial in its production and processing. As an important chemical raw material, phosphoric acid is widely used in fertilizer manufacturing, the food industry, water treatment, and electronic materials, among other fields. However, various tiny particles and suspended solids often become mixed in during the preparation of phosphoric acid. These impurities may originate from the raw materials themselves, byproducts of chemical reactions during production, or residues from production equipment. The presence of these impurities not only reduces the quality of phosphoric acid but may also affect the performance and stability of downstream products.

[0003] Traditional phosphoric acid purification methods primarily remove larger impurity particles through a single filtration process, but their effectiveness in removing fine particles and suspended solids is limited. These fine impurities are difficult to separate effectively from phosphoric acid, affecting not only its transparency but also potentially negatively impacting subsequent production processes, such as clogging pipes and reducing production efficiency.

[0028] Furthermore, the motor 6 is installed in the middle of the top of the cover plate 2, and a rotating rod 7 is fixedly installed on the rotating shaft of the motor 6. The bottom of the rotating rod 7 extends into the interior of the tank 1, and a connecting rod 9 is fixedly installed at the bottom of the rotating rod 7. Three stirring rollers 8 are fixedly installed on both sides of the outer side of the rotating rod 7.

[0029] Furthermore, a partition 10 is fixedly installed inside the tank body 1, and a connecting sleeve 11 is rotatably arranged in the middle of the partition 10. The connecting sleeve 11 is keyed to the connecting rod 9. Material conveying pipes 12 are provided on both sides of the bottom of the partition 10, and solenoid valves are provided at the connection between the material conveying pipes 12 and the partition 10.

[0030] Furthermore, the filter assembly includes a connecting plate 13, a housing 14, a mounting plate 15, a first cleaning brush 16, and a second cleaning brush 17. The housing 14 is fixedly installed on the bottom of the connecting plate 13, and the mounting plate 15 is fixedly installed on the bottom of the housing 14. The first cleaning brush 16 and the second cleaning brush 17 are fixedly installed on both sides of the bottom of the mounting plate 15. A through groove is opened inside the mounting plate 15, and the diameter of the through groove is larger than the distance between the feed pipes 12.

[0031] Furthermore, the connecting plate 13 is fixedly installed on the outside of the connecting sleeve 11, the housing 14 is movably disposed inside the partition 10, and the connection between the housing 14 and the partition 10 is sealed.

[0032] Furthermore, the filter assembly includes a first filter barrel 18 and a second filter barrel 19. The first filter barrel 18 is larger than the second filter barrel 19. The first filter barrel 18 is installed inside the tank 1 by a bracket, and the second filter barrel 19 is installed inside the first filter barrel 18 by a bracket. Both the first filter barrel 18 and the second filter barrel 19 have through holes at their bottoms. A drain pipe 23 is installed at the bottom of the first filter barrel 18, and the other end of the drain pipe 23 extends to the outside of the tank 1. A solenoid valve is installed at the connection between the drain pipe 23 and the first filter barrel 18.

[0033] Furthermore, the outer wall of cleaning brush 16 contacts the inner wall of filter barrel 18, the outer wall of cleaning brush 17 contacts the inner wall of filter barrel 19, and the distance between the feed pipes 12 is less than the inner diameter of filter barrel 19.

[0034] Furthermore, mounting blocks 1 20 are fixedly installed on both sides of the cover plate 2, and mounting blocks 21 are fixedly installed on the top of both sides of the tank body 1.

[0035] Working principle: In use, the device is connected to an external power source and controlled by a controller. Crude phosphoric acid is added through the feed pipe 5, while arsenic removal agents and other reagents are added to the inside of the tank 1. The motor 6 drives the rotating rod 7 and the stirring roller 8 to rotate, and the stirring roller 8 agitates the materials, allowing them to react.

[0036] The reacted phosphoric acid is then introduced to the bottom of the partition 10 through the feed pipe 12. It then undergoes secondary filtration through filter barrels 18 and 19, which effectively removes fine particles and suspended solids. The filtered phosphoric acid is discharged through the discharge pipe 4, thus completing the purification of the phosphoric acid.

[0037] As the rotating rod 7 rotates, it drives the connecting rod 9 to rotate, which in turn drives the connecting plate 13, the housing 14, and the mounting plate 15 to rotate. This, in turn, drives the first cleaning brush 16 and the second cleaning brush 17 to rotate, cleaning the first filter canister 18 and the second filter canister 19. The impurities generated during cleaning can be discharged through the drain pipe 23.

[0038] When cleaning the mixing roller 8 is required, push the cover plate 2 upward to separate the snap-fit ​​plate 22 from the snap-fit ​​groove, and separate the connecting rod 9 from the connecting sleeve 11, so that it can be easily disassembled. When installing, rotate the connecting rod 9 to the position where the connecting sleeve 11 fits, and then install the cover plate 2 so that the snap-fit ​​plate 22 and the snap-fit ​​groove snap together, and the connecting rod 9 is keyed to the connecting sleeve 11.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
