Description

Technical Field

[0001] This utility model relates to the field of water purification technology, and in particular to a nano-semiconductor photocatalytic water purification device. Background Technology

[0002] Photocatalytic degradation membranes utilize radiation and photocatalytic reactions to generate highly reactive free radicals. These free radicals then degrade organic pollutants into inorganic substances through addition, substitution, and electron transfer. This property of photocatalytic degradation membranes is used to purify water, reduce organic pollutants, and improve water quality. Some water purification devices can use photocatalytic degradation membranes to purify incoming water by catalytically degrading organic matter into inorganic substances, thus reducing the organic matter content and making the water cleaner and effectively improving water quality.

[0003] However, we have found that the photocatalytic degradation membrane of water purification equipment on the market needs to be replaced or cleaned after long-term operation to ensure the quality of purification. In traditional equipment, it is very inconvenient to replace or clean the photocatalytic degradation membrane, and some even require complete disassembly for replacement or cleaning.

[0028] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0029] Please see Figure 1-8 This utility model provides an embodiment of a nano-semiconductor photocatalytic water purification device, comprising a body 10, a water pipe 12, a top cover 13, a power supply 14, and a lamp source 20. The power supply 14 is fixedly installed on the upper end face of the top cover 13, and the lamp source 20 is fixedly installed on the lower end face of the top cover 13. The power supply 14 supplies power to the lamp source 20. The bottom of the body 10 is supported by four supports 11. Three sets of mounting plates 18 are provided on the front end face of the body 10. Each mounting plate 18 is detachably mounted with a photocatalytic membrane assembly 22. Each photocatalytic membrane assembly 22 is slidably inserted into the inner cavity of the body 10 and abuts against the rear side wall of the inner cavity of the body 10. Two corner plates 15 are fixedly provided on the left and right edges of the front end face of the body 10. A rotating shaft 16 is rotatably mounted between the two corner plates 15. A pressure rod 17 is fixedly mounted on the rotating shaft 16. Under normal operating conditions, the pressure rod 17 presses against the water pipe 12. The mounting plate 18 is used for limiting and fixing. The water pipe 12 is fixedly installed on the rear end face of the body 10. The water pipe 12 includes an inlet pipe and an outlet pipe. The inlet pipe is installed at the top and the outlet pipe is installed at the bottom. First, water enters the inner cavity of the body 10 through the inlet pipe. At this time, the lamp source 20 irradiates the photocatalytic membrane group 22 at the bottom. The water passes through the photocatalytic membrane group 22. The active oxygen species generated in the photocatalytic membrane group 22 can decompose organic pollutants, bacteria, viruses and other harmful substances in the water, thereby achieving the purpose of water purification. The purified water falls to the bottom and is discharged through the outlet pipe at the bottom. After long-term use, a lot of impurities will remain in the photocatalytic membrane group 22, which will affect the water purification efficiency. Therefore, the photocatalytic membrane group 22 needs to be replaced. When replacing, you only need to open the pressure rod 17 and pull out the mounting plate 18 to replace or clean the photocatalytic membrane group 22, which is very convenient.

[0030] It should be noted that, in order to ensure stability during the water purification process and to facilitate the replacement or cleaning of the photocatalytic membrane module 22, in this embodiment, a limiting groove 26 is provided on the rotating shaft 16, and an inner groove 27 is provided on the lower side of the limiting groove 26 on the rotating shaft 16. A support ring 25 is fixedly installed on the rotating shaft 16, and a limiting cylinder 28 is slidably sleeved on the rotating shaft 16. A stop block 29 is provided in the cavity of the limiting cylinder 28, and the stop block 29 is slidably connected in the limiting groove 26. A return spring is connected between the lower end face of the limiting cylinder 28 and the upper end face of the support ring 25. A limiting plate 30 and an adjusting plate 31 are fixedly installed on the limiting cylinder 28. In normal operation, the limiting plate 30 abuts against the outer end face of the machine body 10. The limiting plate 30 limits the water purification process so that the pressure rod 17 can fully press down the mounting plate 18. When it is necessary to pull out the mounting plate 18, the limiting cylinder 28 is first slid down so that the stop block 29 slides into the inner groove 27. Then, the adjusting plate 31 is rotated so that the limiting plate 30 disengages from the machine body 10, thereby opening the pressure rod 17 and pulling out the mounting plate 18.

[0031] It should be noted that, in order to facilitate the guidance of the water to be purified, so that the water can be dispersed through the photocatalytic membrane group 22 instead of being concentrated in one area, in this embodiment, a flow guide frame 21 is fixedly installed in the inner cavity of the body 10. The flow guide frame 21 is located on the upper side of the photocatalytic membrane group 22. The water inlet pipe extends into the annular inner cavity of the flow guide frame 21, so that the water to be purified is first guided through the annular inner cavity. Overflow holes 23 are distributed in the annular inner cavity. The overflow holes 23 include strip-shaped overflow holes and circular overflow holes. The water flows out from the overflow holes 23 and passes through the photocatalytic membrane group 22. The circular overflow holes have a larger drainage capacity, thereby effectively preventing the water from being concentrated in one area of ​​the photocatalytic membrane group 22 for purification.

[0032] It is worth mentioning that, in order to facilitate the replacement or cleaning of the photocatalytic membrane module 22, in this embodiment, a handle 19 is fixedly installed on the front end face of the mounting plate 18, and two pressure grooves 24 are provided on the front end face of the mounting plate 18, and the pressure rod 17 can be embedded in the corresponding pressure groove 24.

[0033] In practice, the water to be purified flows in through the inlet pipe. At this time, the lamp source 20 shines on the photocatalytic membrane group 22. The active oxygen species generated in the photocatalytic membrane group 22 can decompose organic pollutants, bacteria, viruses and other harmful substances in the water, thereby achieving the purpose of water purification. The purified water falls to the bottom and is discharged through the outlet pipe at the bottom.

[0034] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
