Description

Technical Field

[0001] The invention relates to the technical field of photocatalyst preparation, and in particular to photocatalyst preparation equipment and fabrics having the function of removing odor from fabrics. Background Art

[0002] Photocatalyst is a general term for photo-semiconductor materials with photocatalytic functions, represented by nano-scale titanium dioxide. Under the irradiation of light, the valence band electrons are excited to the conduction band to form photogenerated electron-hole pairs. Holes have strong oxidizing properties and can oxidize water adsorbed on the surface of photocatalysts to generate hydroxyl free radicals, while electrons have reducing properties and can reduce oxygen in the air to superoxide anion free radicals. These free radicals have strong oxidizing ability and can decompose almost all organic matter into carbon dioxide and water. They can also destroy the cell walls of bacteria and the protein shells of viruses, thereby playing a role in sterilization, disinfection, deodorization, and decomposition of organic pollutants.

[0003] The processing methods of photocatalysts are generally divided into gel method, precipitation method, hydrothermal method, sputtering method and chemical vapor deposition method. The principle of precipitation method is to add a precipitant to a metal salt solution to make metal ions form hydroxide or carbonate precipitates, and then filter, wash, dry and roast to obtain photocatalyst materials. After the ion precipitate is generated, water and ion precipitate need to be separated. Traditional separation devices mostly use screens for filtering, but traditional separation devices also have the following defects: First, in order not to destroy the structure of the ion precipitate, centrifugal separation is not used during separation, so the ion precipitate and water can only be separated by a flat screen. During the separation process, the ion precipitate will accumulate in the lower end of the reactor, so it is difficult for the water to quickly pass through the screen and discharge downward; Secondly, after the water is discharged through the screen, the ion precipitation falling on the screen needs to be removed. The traditional method is mostly to remove the ion precipitation falling on the screen by dismantling the screen, but the disassembly and assembly of the screen is relatively cumbersome, which will reduce the collection efficiency of the ion precipitation; Thirdly, when collecting the ion precipitate, the screen needs to be removed so that the ion precipitate will be in contact with the outside air. Then, the ion precipitate may be contaminated by external impurities, which will eventually affect the quality of the photocatalyst. Summary of the invention

The shaft sleeve is arranged at the upper end of the discharge hopper 4, the lifting plug 6 is coaxially arranged in the upper end of the discharge hopper 4 in a columnar shape, and the top of the lifting plug 6 is formed with a circular protrusion 7, and the lower end of the discharge hopper 4 is formed with a discharge pipe 8 that passes downward through the reactor 1. The rotary scraper assembly includes a hollow rotating tube 9 and a plurality of scraper mechanisms 10. The hollow rotating tube 9 is vertically arranged in the reactor 1, and the hollow rotating tube 9 is located above the annular screen 5. The plurality of scraper mechanisms 10 are evenly distributed along the circumferential direction of the hollow rotating tube 9 (such as Figure 8As shown in the figure, each group of scraper mechanisms 10 includes a strip scraper seat and an annular scraper member, the strip scraper seat is connected to the hollow rotating tube 9, the annular scraper member includes an annular conveyor 11 and a plurality of rubber scrapers 12, the annular conveyor 11 is arranged on the strip scraper seat, and the plurality of rubber scrapers 12 are evenly distributed on the annular conveyor 11 along the circumferential direction of the annular conveyor 11, and each strip scraper seat is provided with a driving member for driving the annular conveyor 11 to rotate.

[0019] The device is used to separate ion precipitates produced by a precipitation process. The specific process is as follows: the lifting plug 6 descends to seal the upper end of the discharge hopper 4, and then the ion precipitates and water after the precipitation reaction are poured into the reactor 1 through the feed pipe 2. The ion precipitates and water falling into the reactor 1 will be separated by the annular screen 5, wherein the ion precipitates will be blocked by the annular screen 5, and the water will be discharged downward through the annular screen 5. When the ion precipitates and water are separated, the hollow rotating tube 9 will drive several groups of scraping mechanisms 10 to rotate. During this process, the strip scraping seat in each group of scraping mechanisms 10 will move the ion precipitates on the annular screen 5, so as to promote the water between the ion precipitates to be discharged downward through the annular screen 5. The water passing through the annular screen 5 will fall to the lower end of the reactor 1 and finally be discharged from the drain pipe 3. When all the water is discharged, the lifting plug 6 rises to The upper end of the discharge hopper 4 is opened, and at the same time the driving member drives the annular conveyor 11 to rotate. When the annular conveyor 11 rotates, the ion precipitates falling on the annular screen 5 are pushed inward into the discharge hopper 4 by a number of rubber scrapers 12 on the annular conveyor 11. Finally, the ion precipitates on the annular screen 5 will all enter the discharge hopper 4 and be discharged to the outside of the reactor 1 along the discharge pipe 8. Among them, when the lifting plug 6 descends into the discharge hopper 4, the circular protrusion 7 on the top of the lifting plug 6 will protrude out of the annular screen 5. Then, when the ion precipitates and water fall onto the annular screen 5, the circular protrusion 7 is used to disperse the ion precipitates and water, and promote the ion precipitates and water to fall onto the annular screen 5 around the circular protrusion 7. In summary, the ion precipitates and water are separated by the present device, and the separated ion precipitates and water can be discharged independently, thereby improving the collection efficiency of the ion precipitates.

Then, when the ion precipitate and water are separated, the ion precipitate falling on the annular screen 5 is moved by the strip bottom shell 13 rotating around the hollow rotating tube 9, so as to promote the water between the ion precipitates to pass through the annular screen 5 and discharge downward. When the lifting plug 6 rises, the driving member will drive the annular conveyor 11 to rotate. The rotated annular conveyor 11 will drive the rubber scraper 12 to rotate through a plurality of support bars 17, and finally the ion precipitate falling on the annular screen 5 will be moved into the discharge hopper 4 through the rubber scraper 12. Among them, when the ion precipitate and water fall toward the strip top shell 15, the ion precipitate and water are dispersed through the arc-shaped top surface of the strip top shell 15, so as to prevent the ion precipitate from accumulating on the strip top shell 15.

[0024] In order to show the specific structure of the drive, the following features are set: The driving member includes a rotating rod 22 and a bevel gear group. The rotating rod 22 rotates horizontally in the strip top shell 15. The bevel gear group includes a No. 1 bevel gear 23 and a No. 2 bevel gear 24. The upper end of one of the rotating shafts 18 penetrates upward into the strip top shell 15.

Then, as the hollow rotating tube 9 continues to rotate, the No. 3 bevel gear 25 meshing with the toothed disc 26 will rotate during the revolution, so that the rotating rod 22 will drive the No. 2 bevel gear 24 to rotate. When the No. 2 bevel gear 24 rotates, the No. 1 bevel gear 23 meshing with the No. 2 bevel gear 24 will drive the corresponding rotating shaft 18 to rotate, and the rotating rotating shaft 18 will drive the corresponding rotating wheel 19 to rotate.

When the toothed disc 26 conflicts with the No. 3 bevel gear 25, the toothed disc 26 will be elastically lowered by a plurality of springs 30, so as to prevent the toothed disc 26 and the No. 3 bevel gear 25 from colliding due to hard collision through the elastic decrease of the toothed disc 26, and as the hollow rotating tube 9 continues to rotate, each No. 3 bevel gear 25 will roll on the toothed disc 26. At this time, the elastic decrease of the toothed disc 26 will cause the No. 3 bevel gear 25 to engage with the toothed disc 26. Finally, when the lifting plug 6 stops rising, the spring 30 is compressed to the limit. At this time, the toothed disc 26 is in a fixed state, and the No. 3 bevel gear 25 meshing with the toothed disc 26 will rotate during the revolution.
