DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] The present invention provides a UV-LED photocatalytic film rotary reactor, comprising a body 1 and a cleaning device 2, wherein the cleaning device 2 comprises a shell 21, a motor 22, a rotating drum 23, a rotating shaft 24, an LED light board 25, a spiral blade 26 and a photocatalytic film 27, wherein one end of the shell 21 is fixedly connected to the motor 22, the rotating drum 23 is fixedly connected to the driving shaft of the motor 22, the rotating drum 23 is rotatably connected to the shell 21, the rotating drum 23 is fixedly connected to the inner wall of the rotating drum 23, a No. 1 through hole 241 is provided inside the rotating shaft 24, the LED light board 25 is fixedly connected to the rotating shaft 24, and the LED light board 25 is located in the No. 1 through hole 241, the outer surface of the rotating shaft 24 is fixedly connected to the spiral blade 26, the outer surface of the spiral blade 26 is fixedly connected to the photocatalytic film 27, and the materials of the rotating shaft 24 and the spiral blade 26 are wear-resistant transparent materials.

[0028] In the traditional sewage filtration reaction equipment, the filter plate is used to filter the harmful substances in the sewage. After a long period of filtration, a lot of dirt will accumulate on the outer surface of the filter plate. It is necessary to clean the dirt on the outer surface of the filter plate, which is very troublesome. After the filtration by the filter plate, there are still many residual harmful substances in the sewage. Therefore, the present invention installs a cleaning device 2 in the body 1, introduces the sewage into the shell 21 of the cleaning device 2, and starts the motor 22 to drive the drum 23 to rotate. Since the inner wall of the drum 23 is fixedly connected to the rotating shaft 24, the rotation of the drum 23 drives the rotating shaft 24 to rotate. Since the rotating shaft 24 is fixedly connected with the spiral blade 26, a screw dragon structure is formed, so that the rotating shaft 24 and the spiral blade 26 play the role of conveying sewage. An LED light board 25 is installed inside the rotating shaft 24, and the spiral blade 26 A photocatalytic film 27 is fixedly connected to the outer surface of the blade 26. When the LED light board 25 is turned on, since the material of the rotating shaft 24 and the spiral blade 26 is a wear-resistant transparent material, such as PAM board, the light emitted by the LED lamp can be irradiated onto the photocatalytic film 27 through the rotating shaft 24 and the spiral blade 26, so that the photocatalytic film 27 has higher activity, so that it reacts more fully with the harmful substances in the sewage, thereby achieving a better effect of removing the harmful substances in the sewage. At the same time, when the rotating shaft 24 drives the spiral blade 26 to rotate in an auger structure, the sewage can also fully contact and react with the photocatalytic film 27, thereby better removing the harmful substances in the sewage. A door plug is installed at one end of the rotating shaft 24 to facilitate the removal and maintenance of the LED light board 25 after it is damaged, so that the LED light board 25 is easy to repair.

[0029] As a specific embodiment of the present invention, a foot support 11 is fixedly connected to the lower surface of the body 1, a plurality of cleaning devices 2 are fixedly connected inside the body 1, a liquid inlet hole 12 and a liquid outlet hole 13 are respectively opened on the outer surface of the body 1, a connecting pipe 3 is fixedly connected inside the liquid inlet hole 12 and the liquid outlet hole 13, the connecting pipe 3 is connected to the inside of the shell 21, and the plurality of cleaning devices 2 are connected through the connecting pipe 3.

[0030] When there are too many harmful substances in the sewage, if there is only one cleaning device 2 in the body 1, the cleaning device 2 cannot effectively remove the harmful substances in a large amount of sewage, thereby achieving an ideal removal effect. Therefore, the present invention installs multiple cleaning devices 2 in the body 1, and then connects them two by two through connecting pipes 3. When the sewage enters the shell 21 of the first cleaning device 2 through the connecting pipe 3 in the liquid inlet hole 12, after being cleaned by the first cleaning device 2, the sewage enters the next cleaning device 2 through the connecting pipe 3 and then reacts and treats the harmful substances in the sewage, and so on, until the sewage flows out after being reacted and treated by the last cleaning device 2. The harmful substances in the sewage are cleaned by multiple cleaning devices 2, so that the whole has a better cleaning effect. A foot support 11 is fixedly connected to the lower surface of the body 1 to play a supporting role and facilitate the treated sewage to flow out from the liquid outlet 13.

[0031] As a specific embodiment of the present invention, an opening 14 is opened on one side of the body 1, and the opening 14 is connected to the inside of the shell 21. A sealing door 4 is fixedly connected to the inside of the opening 14, and an annular handle 41 is fixedly connected to the outside of the sealing door 4.

[0032] After long-term use, the activity of the photocatalytic film 27 on the outer surface of the spiral blade 26 will decrease, and it needs to be replaced. The replacement of the photocatalytic film 27 requires disassembling the body 1 and the cleaning device 2, which is very troublesome. Therefore, the present invention installs a sealing door 4 on one side of the body 1. When the photocatalytic film 27 needs to be replaced, it is only necessary to manually turn the handle 41 to open the sealing door 4, take out the entire shaft 24 with the spiral blade 26, and replace the photocatalytic film 27 on the spiral blade 26, thereby achieving the effect of facilitating the replacement of the photocatalytic film 27.

[0033] As a specific embodiment of the present invention, a slot 231 is provided on the inner surface of the rotating drum 23, and a groove No. 1 242 is provided on the outer surface of the rotating shaft 24. A buckle 5 is rotatably connected in the groove No. 1 242, and the buckle 5 is stuck in the slot 231. A spring No. 1 6 is fixedly connected to the lower surface of the buckle 5, and the other end of the spring No. 1 6 is fixedly connected to the inner surface of the groove No. 1 242.

[0034] After the rotating shaft 24 is taken out from the shell 21 through the opening 14 on the body 1 and the photocatalytic film 27 on the spiral blade 26 is replaced, due to the small overall diameter and long length of the shell 21, the staff cannot put their hands into the shell 21 to install the rotating shaft 24. Therefore, the present invention provides a card slot 231 on the inner wall of the drum 23 and a No. 1 groove 242 on the outer surface of the rotating shaft 24. A buckle 5 is rotatably connected in the No. 1 groove 242, and a No. 1 spring 6 is fixedly connected to the lower surface of the buckle 5. The staff only needs to put the rotating shaft 24 into the shell 21 through the opening 14 on the body 1, and push the rotating shaft 24 to the side of the shell 21 close to the drum 23, so that the buckle 5 on the rotating shaft 24 is squeezed into the No. 1 groove 242, and the buckle 5 squeezes the No. 1 spring 6. When the rotating shaft 24 is pushed to the appropriate position, the buckle 5 is clamped in the card slot 231 on the inner wall of the drum 23 due to the elastic force of the No. 1 spring 6, thereby achieving the effect of easy installation.

[0035] As a specific embodiment of the present invention, a No. 2 through hole 243 and a slide groove 244 are provided in the rotating shaft 24, and the No. 2 through hole 243, the slide groove 244 and the No. 1 groove 242 are connected. A push rod 7 is slidably connected in the No. 2 through hole 243, and a pull rope 8 is fixedly connected to the outer surface of the push rod 7, and the other end of the pull rope 8 is fixedly connected to the front end of the buckle 5. One end of the push rod 7 is located outside the No. 2 through hole 243, and the other end of the push rod 7 is fixedly connected to a slider 9. A triangular groove 91 is provided on the outer surface of the slider 9, and one end of the slider 9 is fixedly connected to a No. 2 spring 92, and the other end of the No. 2 spring 92 is fixedly connected to the right side surface of the slide groove 244. A No. 2 groove 2441 is provided on the right side surface of the slide groove 244, and a rotating rod 10 is rotatably connected in the No. 2 groove 2441, and the other end of the rotating rod 10 is rotatably connected to the clamping rod 101, and the clamping rod 101 is located in the triangular groove 91.

[0036] When the buckle 5 is stuck in the slot 231, it is very inconvenient to remove the shaft 24 again because the buckle 5 is stuck in the slot 231. Therefore, the present invention provides a second through hole 243 and a slide slot 244 in the shaft 24, and a push rod 7 is slidably connected in the second through hole 243. When the buckle 5 is stuck in the slot 231, it is only necessary to push the shaft 24 in the direction of the drum 23 to make the push rod 7 move into the second through hole 243. The slider 9 at one end of the push rod 7 squeezes the second spring 92 to move to the right side of the slide slot 244, so that the position of the push rod 7 is offset in the direction of the slide slot 244, thereby pulling the buckle 5. At this time, the rotating rod 10 rotatably connected to the second groove 2441 drives the clamping rod 101 to move in the triangular groove 91 on the slider 9, and the push rod 7 pulls the buckle 5 downward through the pull rope 8 to pull the buckle 5 to the first groove 2441. When the buckle 5 needs to be ejected, the push rod 7 only needs to be squeezed into the No. 2 through hole 243, and the slider 9 at one end of the push rod 7 squeezes the No. 2 spring 92 to move to the right side of the slide groove 244. At this time, the rotating rod 10 rotatably connected to the No. 2 groove 2441 drives the push rod 101 to move out of the notch on the left side of the triangular groove 91 and return to the original notch on the right side. The slider 9 pushes the push rod 7 outward due to the elastic force of the No. 2 spring 92, thereby returning the push rod 7 to its original position. At this time, the pull rope 8 is in a relaxed state, and the buckle 5 returns to its original position, so as to facilitate the next installation of the rotating shaft 24.

[0037] As a specific embodiment of the present invention, one end of the rotating shaft 24 is fixedly connected with an arc block 245, and a contact 2451 is provided on the outer surface of the arc block 245, and the contact 2451 is connected with the circuit of the LED light board 25. The inner surface of the rotating drum 23 is fixedly connected with a No. 3 spring 232 and a No. 4 spring 233, and the No. 3 spring 232 and the No. 4 spring 233 are in contact with the contact 2451 on the outer surface of the arc block 245, and the No. 4 spring 233 is located in the No. 3 spring 232, and the No. 3 spring 232 and the No. 4 spring 233 are connected with an external power supply.

[0038] Since the rotating shaft 24 needs to be taken out, the LED light board 25 in the rotating shaft 24 cannot be directly connected to the power supply. Therefore, the present invention has an arc block 245 fixedly connected to one end of the rotating shaft 24, and a contact 2451 is provided on the outer surface of the arc block 245. The contact 2451 is connected to the circuit of the LED light board 25. A third spring 232 and a fourth spring 233 are fixedly connected to the inner surface of the rotating drum 23, and the third spring 232 and the fourth spring 233 are connected to the external power supply. When the rotating shaft 24 is pushed toward the rotating drum 23, the arc block 245 squeezes the third spring 232. And the No. 4 spring 233, so that the contact 2451 on the outer surface of the arc block 245 is connected with the connection between the No. 3 spring 232 and the No. 4 spring 233, thereby connecting the power supply, so that the LED light board 25 is powered on and illuminated. When the rotating shaft 24 needs to be removed, the No. 3 spring 232 and the No. 4 spring 233 are disengaged from the contact 2451 on the outer surface of the arc block 245, disconnecting the circuit, thereby making it easier to turn on and off the power of the LED light board 25, thereby achieving the effect of facilitating the power supply to connect the LED light board 25. A sealing ring is fixedly connected to the outer surface of the rotating shaft 24 to prevent sewage from entering the drum 23 and damaging the circuit.

[0039] Working principle: In traditional sewage filtration reaction equipment, filter plates are used to filter harmful substances in sewage. After a long period of filtration, a lot of dirt will accumulate on the outer surface of the filter plate. It is necessary to clean the dirt on the outer surface of the filter plate, which is very troublesome. After filtering by the filter plate, there are still many residual harmful substances in the sewage. Therefore, the present invention installs a cleaning device 2 in the body 1, introduces the sewage into the shell 21 of the cleaning device 2, and starts the motor 22 to drive the drum 23 to rotate. Since the inner wall of the drum 23 is fixedly connected to the rotating shaft 24, the rotation of the drum 23 drives the rotating shaft 24 to rotate. Since the rotating shaft 24 is fixedly connected with the spiral blade 26, a screw dragon structure is formed, so that the rotating shaft 24 and the spiral blade 26 play the role of conveying sewage. An LED light board 25 is installed inside the rotating shaft 24. A photocatalytic film 27 is fixedly connected to the outer surface of the spiral blade 26. When the LED light board 25 is turned on, since the material of the rotating shaft 24 and the spiral blade 26 is a wear-resistant transparent material, such as a PAM board, the light emitted by the LED lamp can be irradiated onto the photocatalytic film 27 through the rotating shaft 24 and the spiral blade 26, so that the photocatalytic film 27 has higher activity, so that it reacts more fully with the harmful substances in the sewage, thereby achieving a better effect of removing the harmful substances in the sewage. At the same time, when the rotating shaft 24 drives the spiral blade 26 to rotate in an auger structure, the sewage can also fully contact and react with the photocatalytic film 27, thereby better removing the harmful substances in the sewage. A door plug is installed at one end of the rotating shaft 24 to facilitate the removal and maintenance of the LED light board 25 after it is damaged, thereby making the LED light board 25 easy to repair.

[0040] When there are too many harmful substances in the sewage, only one cleaning device 2 in the body 1 cannot achieve the ideal removal effect of the harmful substances in the sewage. Therefore, the present invention installs multiple cleaning devices 2 in the body 1, and then connects them two by two through connecting pipes 3. When the sewage enters the shell 21 of the first cleaning device 2 through the connecting pipe 3 in the liquid inlet hole 12, after being cleaned by the first cleaning device 2, the sewage enters the next cleaning device 2 through the connecting pipe 3 and then reacts and treats the harmful substances in the sewage, and so on, until the sewage flows out after being reacted and treated by the last cleaning device 2. The harmful substances in the sewage are cleaned by multiple cleaning devices 2, so that the whole has a better cleaning effect. A foot support 11 is fixedly connected to the lower surface of the body 1 to play a supporting role and facilitate the treated sewage to flow out from the liquid outlet 13.

[0041] After long-term use, the activity of the photocatalytic film 27 on the outer surface of the spiral blade 26 will decrease, and it needs to be replaced. The replacement of the photocatalytic film 27 requires disassembling the body 1 and the cleaning device 2, which is very troublesome. Therefore, the present invention installs a sealing door 4 on one side of the body 1. When the photocatalytic film 27 needs to be replaced, it is only necessary to manually turn the handle 41 to open the sealing door 4, take out the entire shaft 24 with the spiral blade 26, and replace the photocatalytic film 27 on the spiral blade 26, thereby achieving the effect of facilitating the replacement of the photocatalytic film 27.

[0042] After the rotating shaft 24 is taken out from the shell 21 through the opening 14 on the body 1 and the photocatalyst on the spiral blade 26 is replaced, due to the small overall diameter and long length of the shell 21, the staff cannot put their hands into the shell 21 to install the rotating shaft 24. Therefore, the present invention provides a card slot 231 on the inner wall of the drum 23 and a No. 1 groove 242 on the outer surface of the rotating shaft 24. A buckle 5 is rotatably connected in the No. 1 groove 242, and a No. 1 spring 6 is fixedly connected to the lower surface of the buckle 5. The staff only needs to put the rotating shaft 24 into the shell 21 through the opening 14 on the body 1, and push the rotating shaft 24 to the side of the shell 21 close to the drum 23, so that the buckle 5 on the rotating shaft 24 is squeezed into the No. 1 groove 242, and the buckle 5 squeezes the No. 1 spring 6. When the rotating shaft 24 is pushed to the appropriate position, the buckle 5 is clamped in the card slot 231 on the inner wall of the drum 23 due to the elastic force of the No. 1 spring 6, thereby achieving the effect of easy installation.

[0043] When the buckle 5 is stuck in the slot 231, it is very inconvenient to remove the shaft 24 again because the buckle 5 is stuck in the slot 231. Therefore, the present invention provides a second through hole 243 and a slide slot 244 in the shaft 24, and a push rod 7 is slidably connected in the second through hole 243. When the buckle 5 is stuck in the slot 231, it is only necessary to push the shaft 24 in the direction of the drum 23 to make the push rod 7 move into the second through hole 243. The slider 9 at one end of the push rod 7 squeezes the second spring 92 to move to the right side of the slide slot 244, so that the position of the push rod 7 is offset in the direction of the slide slot 244, thereby pulling the buckle 5. At this time, the rotating rod 10 rotatably connected to the second groove 2441 drives the clamping rod 101 to move in the triangular groove 91 on the slider 9, and the push rod 7 pulls the buckle 5 downward through the pull rope 8 to pull the buckle 5 to the first groove 2441. When the buckle 5 needs to be ejected, the push rod 7 only needs to be squeezed into the No. 2 through hole 243, and the slider 9 at one end of the push rod 7 squeezes the No. 2 spring 92 to move to the right side of the slide groove 244. At this time, the rotating rod 10 rotatably connected to the No. 2 groove 2441 drives the push rod 101 to move out of the notch on the left side of the triangular groove 91 and return to the original notch on the right side. The slider 9 pushes the push rod 7 outward due to the elastic force of the No. 2 spring 92, thereby returning the push rod 7 to its original position. At this time, the pull rope 8 is in a relaxed state, and the buckle 5 returns to its original position, so as to facilitate the next installation of the rotating shaft 24.

[0044] Since the rotating shaft 24 needs to be taken out, the LED light board 25 in the rotating shaft 24 cannot be directly connected to the power supply. Therefore, the present invention has an arc block 245 fixedly connected to one end of the rotating shaft 24, and a contact 2451 is provided on the outer surface of the arc block 245. The contact 2451 is connected to the circuit of the LED light board 25. A third spring 232 and a fourth spring 233 are fixedly connected to the inner surface of the rotating drum 23, and the third spring 232 and the fourth spring 233 are connected to the external power supply. When the rotating shaft 24 is pushed toward the rotating drum 23, the arc block 245 squeezes the third spring 232. And the No. 4 spring 233, so that the contact 2451 on the outer surface of the arc block 245 is in contact with the No. 3 spring 232 and the No. 4 spring 233, thereby connecting the power supply and making the LED light board 25 powered on and light up. When the rotating shaft 24 needs to be removed, the No. 3 spring 232 and the No. 4 spring 233 are disengaged from the contact 2451 on the outer surface of the arc block 245, disconnecting the circuit, thereby making it easier to turn on and off the power of the LED light board 25, thereby achieving the effect of facilitating the power supply to connect the LED light board 25.
