Description

Technical Field

[0001] The present invention relates to the technical field of photocatalyst preparation, and specifically relates to a photocatalyst preparation device and fabric with the function of removing odor from fabrics. Background Art

[0002] Photocatalyst is a general term for a kind of photocatalytic functional semiconductor material represented by nanoscale titanium dioxide. Under the irradiation of light, valence band electrons are excited to the conduction band, forming photo-generated electron-hole pairs. The holes have strong oxidizing properties and can oxidize the water adsorbed on the surface of the photocatalyst to generate hydroxyl radicals, while the electrons have reducing properties and can reduce the oxygen in the air to superoxide anion radicals. These radicals have strong oxidizing ability and can decompose almost all organic substances into carbon dioxide and water, and can also destroy the cell walls of bacteria and the protein shells of viruses, thereby playing roles such as sterilization, disinfection, deodorization, and decomposition of organic pollutants.

[0003] The processing methods of photocatalysts are usually divided into the sol-gel method, precipitation method, hydrothermal method, sputtering method, and chemical vapor deposition method. Among them, the principle of the precipitation method is that by adding a precipitant to a metal salt solution, metal ions form precipitates such as hydroxides or carbonates, and then through processes such as filtration, washing, drying, and calcination, the photocatalyst material is obtained. After the ionic precipitate is formed, it is necessary to separate the water and the ionic precipitate. Most traditional separation devices use a sieve for filtration, but traditional separation devices also have the following defects:

[0004] First, in order not to damage the structure of the ionic precipitate, the centrifugal separation method is not used during separation, so only a flat sieve can be used to separate the ionic precipitate and water. During the separation process, since the ionic precipitate will accumulate at the lower end of the reaction kettle, it is difficult for water to quickly pass through the sieve and drain downward;

[0005] Second, after the water is drained through the sieve, it is necessary to remove the ionic precipitate that has fallen on the sieve. Most traditional methods use the method of removing the sieve to take out the ionic precipitate that has fallen on the sieve, but the disassembly and assembly of the sieve are relatively cumbersome, thus reducing the collection efficiency of the ionic precipitate;

[0006] Third, when collecting the ionic precipitate, since the sieve needs to be removed, the ionic precipitate will come into contact with the outside air, so the ionic precipitate may be contaminated by external impurities, ultimately affecting the quality of the photocatalyst. Summary of the Invention

[0007] Based on this, it is necessary to provide a photocatalyst preparation device and fabric with the function of removing odor from fabrics in view of the problems in the prior art.

[0017] The beneficial effects of the present invention compared with the prior art are as follows:

[0018] First, during the process of ion precipitation and water falling onto the annular screen, the hollow rotating tube will drive several groups of scraping mechanisms to stir the ion precipitation falling on the annular screen, thereby promoting the water between the ion precipitations to drain out through the annular screen and preventing the water from not being completely drained due to the accumulation of ion precipitation;

[0019] Second, after the water is completely drained, the lifting plug will rise to open the upper end of the discharge hopper. At the same time, as the hollow rotating tube rotates, the driving member will drive the annular belt to rotate. When the annular belt rotates, the annular belt will synchronously drive several rubber scraping plates to scrape the ion precipitation on the annular screen into the discharge hopper. Finally, the ion precipitation will be discharged through the discharge pipe. The automatic scraping of the scraping mechanism is used to discharge the ion precipitation on the annular screen, thus eliminating the trouble of disassembling and assembling the screen and further improving the collection efficiency of the ion precipitation;

[0020] Third, since the ion precipitation is scraped into the discharge hopper by the scraping mechanism, when collecting the ion precipitation, the ion precipitation will not come into contact with external impurities, ultimately improving the quality of the photocatalyst.

Detailed implementation manners

[0036] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0037] Reference Figures 1 to 14The photocatalyst preparation equipment for removing odor from the shown fabric includes a reaction kettle 1 arranged vertically. A feed pipe 2 is provided at the top of the reaction kettle 1, and a drain pipe 3 is provided at the bottom of the reaction kettle 1. A filtering component and a rotary scraping component are arranged inside the reaction kettle 1. The filtering component includes a discharge hopper 4, an annular screen 5, and a lifting plug 6. The discharge hopper 4 is arranged vertically inside the reaction kettle 1 and is coaxial with the reaction kettle 1. The annular screen 5 is arranged horizontally inside the reaction kettle 1, and the inner circle of the annular screen 5 is coaxially sleeved on the upper end of the discharge hopper 4. The lifting plug 6 is arranged coaxially in the upper end of the discharge hopper 4 in a columnar shape, and a circular convex block 7 is formed on the top of the lifting plug 6. A discharge pipe 8 that penetrates downward through the reaction kettle 1 is formed at the lower end of the discharge hopper 4. The rotary scraping component includes a hollow rotating pipe 9 and several groups of scraping mechanisms 10. The hollow rotating pipe 9 is arranged vertically inside the reaction kettle 1 and is located above the annular screen 5. Several groups of scraping mechanisms 10 are evenly distributed along the circumferential direction of the hollow rotating pipe 9 (as Figure 8 shown). Each group of scraping mechanisms 10 includes a strip-shaped scraping seat and an annular scraping part. The strip-shaped scraping seat is connected to the hollow rotating pipe 9. The annular scraping part includes an annular running belt 11 and several rubber scraping plates 12. The annular running belt 11 is arranged on the strip-shaped scraping seat, and several rubber scraping plates 12 are evenly distributed along the circumferential direction of the annular running belt 11 on the annular running belt 11. A driving part for driving the annular running belt 11 to rotate is provided on each strip-shaped scraping seat.

[0038] This device is used to separate the ion precipitate produced by the 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 precipitate and water after the precipitation reaction are poured into the reactor 1 through the feed pipe 2. The ion precipitate and water falling into the reactor 1 will be separated by the annular screen 5, wherein the ion precipitate will be blocked by the annular screen 5, and the water will be discharged downward through the annular screen 5. When the ion precipitate 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 precipitate 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. The upper end of the discharge hopper 4 is opened, and at the same time the driving part will drive the annular conveyor 11 to rotate. When the annular conveyor 11 rotates, the ion precipitates falling on the annular screen 5 will be pushed inward into the discharge hopper 4 by several 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 outside the annular screen 5. Then, when the ion precipitates and water fall onto the annular screen 5, the circular protrusion 7 will 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 this device, and the separated ion precipitates and water can be discharged independently, thereby improving the collection efficiency of the ion precipitates.

[0039] In order to show the specific structure of the strip scraper seat, the following features are set:

[0040] Each strip scraper seat includes a strip bottom shell 13, a strip baffle shell 14 and a strip top shell 15. The strip bottom shell 13 is horizontal, and the top of the strip bottom shell 13 is an open structure. A number of vertically upward connecting columns 16 are formed in the strip bottom shell 13. The strip baffle shell 14 is arranged above the strip bottom shell 13. The strip baffle shell 14 and the strip bottom shell 13 are spaced apart. The bottom of the strip baffle shell 14 is an open structure, and the strip baffle shell 14 covers the several connecting columns 16. The strip baffle shell 14 is fixedly connected to the strip bottom shell 13 through several connecting columns 16. The strip top shell 15 is fixed to the top of the strip baffle shell 14. The top surface of the strip top shell 15 is arc-shaped. Each strip top shell 15 is connected to the lower end of the hollow rotating tube 9. The annular conveyor 11 is arranged in the strip bottom shell 13. Several branches 17 passing through the strip bottom shell 13 and the strip baffle shell 14 are formed on the annular conveyor 11. Each rubber scraper 12 is connected to the corresponding branch 17.

[0041] When the hollow rotating tube 9 rotates, the hollow rotating tube 9 will drive the strip-shaped retaining shell 14 and the strip-shaped bottom shell 13 to rotate together through the strip-shaped top shell 15. Then, when separating the ion precipitate from the water, the strip-shaped bottom shell 13 rotating around the hollow rotating tube 9 stirs the ion precipitate falling on the annular screen 5, so as to promote the water between the ion precipitates to pass through the annular screen 5 and drain downward. After the lifting plug 6 rises, the driving member will drive the annular belt 11 to rotate. The rotated annular belt 11 will drive the rubber scraping plate 12 to rotate through a plurality of support bars 17. Finally, the ion precipitate falling on the annular screen 5 is stirred into the discharge hopper 4 by the rubber scraping plate 12. Among them, when the ion precipitate and water fall onto the strip-shaped top shell 15, the arc-shaped top surface of the strip-shaped top shell 15 is used to disperse the ion precipitate and water, so as to prevent the ion precipitate from accumulating on the strip-shaped top shell 15.

[0042] In order to show how the annular belt 11 is installed, the following features are set:

[0043] There are two symmetrically arranged rotating shafts 18 in the strip-shaped retaining shell 14. The upper end of each rotating shaft 18 is rotatably connected to the top of the strip-shaped retaining shell 14. The lower end of each rotating shaft 18 penetrates downward into the strip-shaped bottom shell 13. A runner 19 is coaxially fixed to the lower end of each rotating shaft 18. The annular belt 11 is sleeved on the two runners 19. An expansion mouth retaining cover 20 is provided at the lower end of the hollow rotating tube 9. A plurality of horizontal support rods 21 corresponding to the strip-shaped scraping seats are formed on the expansion mouth retaining cover 20. Each strip-shaped top shell 15 is fixedly connected to the corresponding horizontal support rod 21.

[0044] After the hollow rotating tube 9 rotates, the hollow rotating tube 9 will drive a plurality of horizontal support rods 21 to rotate through the expansion mouth retaining cover 20. Thus, a plurality of strip-shaped scraping seats will rotate synchronously. The driving member drives the annular belt 11 to rotate by driving the runner 19 to rotate. Thus, the rotation of the annular belt 11 drives a plurality of rubber scraping plates 12 to stir the ion precipitate falling on the annular screen 5 into the discharge hopper 4.

[0045] In order to show the specific structure of the driving member, the following features are set:

[0046] The driving member includes a rotating rod 22 and a bevel gear set. The rotating rod 22 rotates horizontally in the strip-shaped top shell 15. The bevel gear set includes a first bevel gear 23 and a second bevel gear 24. The upper end of one of the rotating shafts 18 penetrates upward into the strip-shaped top shell 15. The first bevel gear 23 is coaxially fixed to the rotating shaft 18 penetrating into the strip-shaped top shell 15. The second bevel gear 24 is coaxially fixed to the rotating rod 22. And the first bevel gear 23 meshes with the corresponding second bevel gear 24. One end of the rotating rod 22 penetrates into the expansion mouth retaining cover 20. A third bevel gear 25 is coaxially fixed to the end of the rotating rod 22 penetrating into the expansion mouth retaining cover 20. A toothed disc 26 horizontally connected to the circular convex block 7 is provided in the expansion mouth retaining cover 20. Each third bevel gear 25 can mesh with the toothed disc 26.

[0047] When the hollow rotating tube 9 rotates, the hollow rotating tube 9 will drive the flaring baffle 20 to rotate. Thus, the third bevel gear 25 connected to the rotating rod 22 will revolve around the gear disk 26. When the lifting plug 6 rises, the lifting plug 6 will drive the gear disk 26 to gradually approach the third bevel gear 25 upward. Thus, the third bevel gear 25 will mesh with the gear disk 26. Then, with the continuous rotation of the hollow rotating tube 9, the third bevel gear 25 meshing with the gear disk 26 will rotate on its own during the revolution. Thus, the rotating rod 22 will drive the second bevel gear 24 to rotate. When the second bevel gear 24 rotates, the first bevel gear 23 meshing with the second bevel gear 24 will drive the corresponding rotating shaft 18 to rotate. The rotating rotating shaft 18 will drive the corresponding runner 19 to rotate. Finally, the entire annular belt 11 will be driven to rotate by the runner 19.

[0048] In order to show how the gear disk 26 is connected to the lifting plug 6, the following features are provided:

[0049] A number of limiting pins 27 evenly distributed along the circumferential direction of the gear disk 26 are formed at the bottom of the gear disk 26. A number of vertical slots 28 corresponding to the limiting pins 27 are formed on the circular convex block 7. A number of columnar sleeves 29 corresponding to the vertical slots 28 are formed on the circular convex block 7. Each limiting pin 27 vertically passes through the columnar sleeve 29 and is inserted into the corresponding vertical slot 28. A vertical spring 30 is sleeved on each limiting pin 27. Two ends of the spring 30 respectively abut against the gear disk 26 and the columnar sleeve 29.

[0050] When the lifting plug 6 rises, the lifting plug 6 will drive the gear disk 26 to gradually approach the third bevel gear 25 upward. When the gear disk 26 abuts against the third bevel gear 25, the gear disk 26 will elastically descend through a number of springs 30. Thus, the elastic descent of the gear disk 26 is used to prevent the gear disk 26 and the third bevel gear 25 from hitting teeth due to hard collision. And with the continuous rotation of the hollow rotating tube 9, each third bevel gear 25 will roll on the gear disk 26. At this time, the elastic descent of the gear disk 26 is used to promote the meshing of the third bevel gear 25 and the gear disk 26. Finally, when the lifting plug 6 stops rising, the spring 30 is compressed to the limit. At this time, the gear disk 26 is in a fixed state. Then, the third bevel gear 25 meshing with the gear disk 26 will rotate on its own during the revolution.

[0051] In order to show how the hollow rotating tube 9 rotates, the following features are provided:

[0052] At the top of the reaction kettle 1, an installation opening 31 is coaxially formed. Inside the installation opening 31, a riser pipe 32 is fixedly arranged and vertically penetrates into the reaction kettle 1. Inside the riser pipe 32, a number of bearings 33 are embedded and evenly distributed at equal intervals in the vertical direction. The upper end of the hollow rotating pipe 9 passes through the riser pipe 32, and the hollow rotating pipe 9 is connected to a number of bearings 33. At the top of the reaction kettle 1, a motor 34 is fixedly arranged beside the hollow rotating pipe 9. The motor 34 is vertical, and a first synchronous pulley 35 is coaxially fixed on the output end of the motor 34. A second synchronous pulley 36 is coaxially sleeved on the upper end of the hollow rotating pipe 9. A synchronous belt 37 is sleeved on the first synchronous pulley 35 and the second synchronous pulley 36.

[0053] When the motor 34 is started, the motor 34 will drive the synchronous belt 37 to rotate through the first synchronous pulley 35. In this way, the synchronous belt 37 will drive the hollow rotating pipe 9 to rotate through the second synchronous pulley 36. Finally, the hollow rotating pipe 9 will drive a number of scraping mechanism 10 to rotate.

[0054] In order to show how the lifting plug 6 is lifted and lowered, the following features are set:

[0055] Inside the hollow rotating pipe 9, a first limiting sleeve 38 is coaxially fixed. Inside the discharge hopper 4, a second limiting sleeve 39 is coaxially fixed. Inside the hollow rotating pipe 9, a lifting rod 40 is coaxially arranged and passes through the first limiting sleeve 38. The upper end of the lifting rod 40 passes out of the hollow rotating pipe 9. The lower end of the lifting rod 40 is fixedly connected to the circular convex block 7. At the bottom of the lifting plug 6, a limiting insertion rod 41 is vertically formed and inserted into the second limiting sleeve 39. At the upper end of the limiting insertion rod 41, a limiting ring 42 is formed and abuts downward against the top of the second limiting sleeve 39. Above the reaction kettle 1, a vertical cylinder 43 is fixedly arranged. The upper end of the lifting rod 40 is coaxially fixedly connected to the output end of the cylinder 43.

[0056] The cylinder 43 is used to drive the lifting rod 40 to lift and lower, and drive the lifting plug 6 to lift and lower through the lifting rod 40. The first limiting sleeve 38 and the second limiting sleeve 39 are used to limit the lifting rod 40, so as to ensure the stability of the lifting rod 40 during lifting and lowering. When the lifting plug 6 descends, the limiting ring 42 arranged on the limiting insertion rod 41 will downwardly rest on the top of the second limiting sleeve 39, so as to limit the downward travel of the lifting plug 6.

[0057] In order to show how the discharge pipe 8 and the annular screen 5 are installed, the following features are set:

[0058] Inside the lower end of the reaction kettle 1, a vertical installation sleeve 44 is fixedly arranged. The lower end of the discharge pipe 8 passes through the installation sleeve 44 and is fixedly connected to the installation sleeve 44. On the inner wall of the reaction kettle 1, a ring-shaped retaining ring 45 is formed. The outer ring of the annular screen 5 downwardly rests on the ring-shaped retaining ring 45.

[0059] When installing the annular screen 5, first fix the inner ring of the annular screen 5 on the outer wall of the upper end of the discharge hopper 4, and then insert the discharge pipe 8 connected to the discharge hopper 4 downward into the installation sleeve 44. During this process, the outer ring of the annular screen 5 will be placed downward on the retaining ring 45, so as to limit the downward travel of the annular screen 5 through the retaining ring 45. After the annular screen 5 stops descending, then fix the discharge pipe 8 and the installation sleeve 44 together.

[0060] Odor-removing fabric, the fabric contains photocatalyst, and removes odors through the reaction of the photocatalyst with natural light, enabling the fabric to have the function of removing odors. And the photocatalyst also contains hydrophobic and oleophobic molecules, so the fabric containing photocatalyst also has waterproof and oil-proof functions.

[0061] Working principle:

[0062] This device is used to separate the ionic precipitate produced by the precipitation process. The specific process is as follows: the lifting plug 6 descends to block the upper end of the discharge hopper 4, and then pour the ionic precipitate and water after the precipitation reaction into the reaction kettle 1 through the feed pipe 2. The ionic precipitate and water falling into the reaction kettle 1 will be separated by the annular screen 5. Among them, the ionic precipitate will be intercepted by the annular screen 5, and the water will pass through the annular screen 5 and drain downward. When the ionic precipitate and water are separated, the hollow rotating tube 9 will drive several groups of scraping mechanisms 10 to rotate. During this process, the strip-shaped scraping seats in each group of scraping mechanisms 10 will stir the ionic precipitate on the annular screen 5, so as to promote the water between the ionic precipitates to drain downward through the annular screen 5. The water passing through the annular screen 5 will fall to the lower end of the reaction kettle 1 and finally drain out from the drain pipe 3. After all the water is drained, the lifting plug 6 rises to open the upper end of the discharge hopper 4. At the same time, the driving part will rotate the annular belt 11. After the annular belt 11 rotates, the ionic precipitate falling on the annular screen 5 will be inwardly dialed into the discharge hopper 4 by several rubber scrapers 12 on the annular belt 11. Finally, all the ionic precipitate on the annular screen 5 will enter the discharge hopper 4 and drain out of the reaction kettle 1 along the discharge pipe 8. Among them, when the lifting plug 6 descends into the discharge hopper 4, the circular convex block 7 provided on the top of the lifting plug 6 will protrude outside the annular screen 5. Then when the ionic precipitate and water fall onto the annular screen 5, the circular convex block 7 is used to disperse the ionic precipitate and water, promoting the ionic precipitate and water to fall onto the annular screen 5 on the circumferential side of the circular convex ring. To sum up, through this device, the ionic precipitate and water are separated, and the separated ionic precipitate and water can be discharged independently, improving the collection efficiency of the ionic precipitate.
