Description

Technical Field

[0001] The invention belongs to the technical field related to sewage treatment, and specifically relates to a rotating rolling type photocatalytic reaction device. Background Art

[0002] A large amount of water containing pollutants is easily generated during the industrial production process. If it is directly discharged into the natural environment, it will pollute groundwater, affect the safety of drinking water sources, and affect the balance of the entire water ecosystem. Therefore, a rotating rolling photocatalytic reaction equipment is set up to treat industrial wastewater. The catalyst is activated by light irradiation to remove pollutants in the water and achieve the purpose of purifying sewage. It can degrade or transform various types of organic pollutants, inorganic ions, etc., and effectively respond to the treatment needs of industrial wastewater, domestic sewage, etc.

[0003] After searching, the Chinese patent application number 202310908828.6 discloses a skid-mounted expandable continuous photocatalytic reaction equipment and a method of use, which can be widely used in the field of photocatalytic synthesis technology, and solves the technical problems of high operational risk factor, high energy consumption, large investment, and poor batch stability in the preparation of photocatalytic materials in the prior art. It includes a shell, a control system, a metering component, a reaction device, and a heat dissipation device. The reaction device includes an ultraviolet mercury lamp combination and a quartz reaction tube combination. The quartz reaction tube combination matches the ultraviolet mercury lamp combination. The quartz reaction tube combination includes a first quartz reaction tube combination and a second quartz reaction tube combination, which are respectively arranged on both sides of the ultraviolet mercury lamp combination, and each is provided with a water inlet and a water outlet. The water outlet of the first quartz reaction tube combination is connected to the water inlet of the second quartz reaction tube combination, and the water outlet of the second quartz reaction tube combination is connected to the total reaction water outlet pipe, and the water inlet of the first quartz reaction tube combination is connected to the total reaction water inlet pipe;

[0004] The above patent still has the following shortcomings: it is inconvenient to take and place the catalyst. The catalyst used in the existing device is usually a solid catalyst or a suspended catalyst. However, due to the narrow internal pipeline of the device, it takes a long time to replace and load the solid catalyst, which will affect the continuous operation of the equipment and the overall processing efficiency. The direct use of suspended catalysts requires additional separation and purification steps, which reduces the convenience of using the device.

DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] See also Figure 1-9 The present invention provides a technical solution: a rotating rolling photocatalytic reaction device, comprising a base frame 1, and also comprising:

[0051] A protective shell is arranged on the top of the bottom frame 1;

[0052] A purification box is arranged on one side of the top of the base frame 1, and a photocatalyst rod core 19 is arranged inside the purification box;

[0053] A metering pump 22 is installed on the other side of the top of the base frame 1, and a shunt pipe 11 is installed on one side of the metering pump 22;

[0054] The separation structure 2 is arranged on one side of the metering pump 22 and is used to filter the sewage entering the metering pump 22;

[0055] A water inlet pipe 10 is arranged on one side of the separation structure 2;

[0056] The pick-and-place structure 7 is arranged at the top of the box body 12 and is used to automatically replace the photocatalyst rod core 19;

[0057] The loading and unloading structure 8 is arranged at the bottom end of the placing and taking structure 7 and is used to fix the position of the photocatalyst rod core 19 .

[0058] In this embodiment, the photocatalyst rod core 19 is installed in the use position of the purification box through the cooperation of the placement structure 7 and the loading and unloading structure 8. The purification box processes the sewage, and the metering pump 22 is used to extract and transport the sewage in the separation structure 2.

[0059] like Figures 1 to 4 As shown, the protective shell includes a shell 5 detachably mounted on the top of the base frame 1, a control panel 3 mounted on one side of the shell 5, a display 4 mounted on the top of one side of the shell 5, and a loading port 9 opened inside the other side of the shell 5, and the purification box includes a box body 12 mounted on one side of the top of the base frame 1, support frames 14 fixed at both ends of the box body 12, a drainage pipe 6 installed inside one group of the support frames 14, an ultraviolet mercury lamp 15 mounted on the top of the support frame 14, a reflective sheet 17 fixed on the inner wall of the box body 12, a glass cylinder 16 mounted on both sides of the box body 12, a spiral blade 18 fixed on the inner wall of the glass cylinder 16, a first connecting pipe 20 installed on one side of the top of the spiral blade 18 and connected to the drainage pipe 6, a second connecting pipe 21 fixed at the bottom end of one side of the glass cylinder 16 and connected to the diversion pipe 11, and a guide pipe 13 fixed at the bottom end of the glass cylinder 16.

[0060] In this embodiment, the device is placed in the use position, and the photocatalyst rod core 19 is installed inside the glass cylinder 16 by using the cooperation of the pick-up and placement structure 7 and the loading and unloading structure 8, and the water inlet pipe 10 is connected with the sewage pipeline, so that the sewage is introduced into the separation structure 2 through the water inlet pipe 10, and the suspended matter and solid particles in the sewage are filtered by the separation structure 2 to make the sewage clear and transparent. Then the sewage enters the inside of the metering pump 22, and the metering pump 22 sucks the sewage into the inside of the diversion pipe 11. The sewage in the diversion pipe 11 is evenly injected into the glass cylinder 16 through the second connecting pipe 21, so that the sewage contacts the photocatalyst rod core 19, and the ultraviolet mercury lamp 15 generates light to irradiate the photocatalyst rod core 19, thereby degrading or converting various types of organic pollutants in the sewage. The pollutants are purified by the sewage. Meanwhile, the reflective sheet 17 reflects the light to improve the utilization efficiency of the ultraviolet mercury lamp 15. The establishment of the spiral blades 18 prolongs the flow time of the sewage in the glass cylinder 16 and the contact time between the sewage and the photocatalyst rod core 19. Meanwhile, turbulence is easily generated when the sewage flows on the surface of the spiral blades 18 to ensure that the sewage is in full contact with the photocatalyst rod core 19. The sewage after the reaction is discharged from the glass cylinder 16 through the first connecting pipe 20 and re-enters the interior of the drain pipe 6. The drain pipe 6 discharges the treated sewage out of the device. When the reaction efficiency is low, the photocatalyst rod core 19 in the glass cylinder 16 is taken out through the pick-and-place structure 7 and the loading and unloading structure 8, so that the staff can clean and replace the surface of the photocatalyst rod core 19.

[0061] like Figure 3 , Figure 4 and Figure 8As shown, the pick-and-place structure 7 includes a guide frame 703 fixed to the top of both sides of the box body 12, a first movable groove 701 opened on one side of the guide frame 703, a second movable groove 702 opened on the other side of the guide frame 703, a guide cylinder 710 fixed to the top of the box body 12, a connecting seat 711 sliding inside the guide cylinder 710, a second movable groove 702 fixed to one side of the connecting seat 711, a positioning groove 713 opened on one side of the guide cylinder 710 and slidably connected to the positioning block 712, a connecting plate 706 fixed to the top of the connecting seat 711, a second movable rod 704 installed on one side of the top of the connecting plate 706, a first movable rod 705 installed on the other side of the top of the connecting plate 706, and A moving rod 705 and a bearing 709 on the outside of the connecting plate 706, a guide wheel 708 fixed on the outside of the bearing 709 and slidingly connected to the first moving groove 701 and the second moving groove 702, and a hydraulic push rod 707 rotatably connected to one side of the top of the base frame 1 and rotatably connected to the second moving rod 704, there are two groups of guide frames 703, the two groups of guide frames 703 are symmetrically distributed on the vertical center line of the box body 12, the front cross-section of the second moving groove 702 is an inverted "J" shape structure, when the second moving rod 704 slides in the arc-shaped groove at the top of the second moving groove 702, the first moving rod 705 is located at the top of the first moving groove 701, and the first moving rod 705 rotates inside the first moving groove 701.

[0062] In this embodiment, when taking and placing the photocatalyst rod core 19, the hydraulic push rod 707 is extended to push the second moving rod 704 upward, so that the second moving rod 704 slides inside the second moving groove 702 and drives the connecting plate 706 to move upward, and then the connecting plate 706 drives multiple groups of unloading structures 8 and the photocatalyst rod core 19 to move upward through the connecting seat 711. At the same time, the connecting plate 706 pushes the first moving rod 705 to slide inside the first moving groove 701, guides the movement of the connecting plate 706, and makes the connecting plate 706 move straight upward, and drives the loading and unloading structure 8 and the photocatalyst rod core 19 to leave the inside of the glass tube 16. When the first moving rod 705 moves to the top of the first moving groove 701, the loading and unloading structure 8 and the photocatalyst rod core 19 completely leave the inside of the glass tube 16, and at the same time, the first moving rod 705 stops moving, and the second moving rod 704 is at the top of the second moving groove 702 under the thrust of the hydraulic push rod 707. The first moving rod 705 slides in the arc-shaped groove, forcing the first moving rod 705 to rotate at the top of the first moving groove 701, thereby driving the connecting plate 706 to rotate around the first moving rod 705, placing multiple groups of photocatalyst rod cores 19 and the loading and unloading structure 8 horizontally, and allowing them to pass through the loading port 9 to leave the interior of the shell 5, so that the staff can directly clean or replace the photocatalyst rod core 19. After the processing is completed, the hydraulic push rod 707 is started to contract to insert the photocatalyst rod core 19 and the loading and unloading structure 8 into the interior of the glass tube 16. The first moving rod 705 is used to roll inside the first moving groove 701 or the second moving groove 702 through the guide wheel 708 to reduce the friction between the first moving rod 705 and the second moving rod 704, so that the device can run more smoothly. The installation of the connecting seat 711 is guided by the positioning block 712 and the positioning groove 713 to prevent displacement and misalignment, thereby ensuring the accurate installation position of the photocatalyst rod core 19 and the loading and unloading structure 8.

[0063] like Figures 5 and 6 As shown, the loading and unloading structure 8 includes an outer cylinder 802 fixed at the bottom end of the connecting seat 711, an inner rod 801 slidably connected to the bottom end of the outer cylinder 802, a compression spring 803 fixed to the outside of the inner rod 801 and connected to the outer cylinder 802, a rubber pad 807 fixed to the bottom end of the inner rod 801, a push arm 808 rotatably connected to the outside of the inner rod 801, a push plate 804 rotatably connected to one side of the push arm 808, a guide arm 805 rotatably connected between the push plate 804 and the inner rod 801, and a sealing gasket 806 fixed to one side of the push plate 804, two groups of guide arms 805 are rotatably connected on one side of the push plate 804, and the two groups of guide arms 805 are distributed in parallel, the inner rod 801 forms a telescopic mechanism with the outer cylinder 802 through the compression spring 803, the diameter of the rubber pad 807 is larger than the inner diameter of the guide tube 13, and the photocatalyst rod core 19 is mounted on the surface of the push plate 804 by bolts.

[0064] In this embodiment, when the connection seat 711 pushes the loading and unloading structure 8 to be inserted into the interior of the glass tube 16, the rubber pad 807 first contacts the bottom of the glass tube 16. As the connection seat 711 continues to move downward, the rubber pad 807 pushes the inner rod 801 to slide toward the interior of the outer tube 802 and squeezes the compression spring 803 to contract. At the same time, the inner rod 801 pushes one side of the push arm 808 to expand and drive the push plate 804 to move. The movement of the push plate 804 is guided by two sets of parallel guide arms 805, so that the push plate 804 is always parallel to the inner wall of the glass tube 16 during the movement. The push plate 804 contacts the inner wall of the glass tube 16, and the photocatalyst rod core 19 is inserted into the glass tube 1. 6, and the sealing pad 806 is used to seal between the push plate 804 and the glass cylinder 16 to prevent leakage of liquid sewage, and complete the installation of the photocatalyst rod core 19. The connecting seat 711 is used to seal the top of the glass cylinder 16, and the rubber pad 807 is used to seal the guide tube 13 to prevent sewage leakage and overflow. When the hydraulic push rod 707 pushes the connecting seat 711 to move upward, the compressed compression spring 803 is able to push the inner rod 801 to move downward, so that the push plate 804 brought by the push arm 808 is reset and drives the photocatalyst rod core 19 to leave the interior of the glass cylinder 16, so as to facilitate the removal of the photocatalyst rod core 19. In this process, sewage accidentally leaked can be discharged through the guide tube 13.

[0065] like Figure 7 As shown, the separation structure 2 includes a support seat 209 fixed on one side of the top of the base frame 1, a filter cartridge 203 installed on the top of the support seat 209 and connected to the water inlet pipe 10, a drive motor 205 installed inside the filter cartridge 203, a transmission shaft 208 rotatably connected to the inside of the drive motor 205, a scraper 207 fixed on the outside of the transmission shaft 208, a drive motor 205 installed on one side of the filter cartridge 203, a transmission belt 204 installed on the end of the output shaft of the transmission shaft 208 and connected to the end of the input shaft of the transmission shaft 208, a sewage pipe 202 fixed inside one side of the filter cartridge 203 and connected to the filter screen 206, and a sealing plug 201 inserted inside the sewage pipe 202, the outer wall of the sealing plug 201 is provided with an external thread, and the interior of the sewage pipe 202 is provided with an internal thread that cooperates with the external thread.

[0066] In this embodiment, when sewage is introduced, the sewage enters the interior of the filter 206 through the water inlet pipe 10, and the filter 206 filters the suspended matter and particulate matter in the sewage, causing them to accumulate on the inner wall of the filter 206. The clarified sewage passes through the filter 206 and is sucked in by the metering pump 22, and the drive motor 205 is started to rotate, so that the drive motor 205 drives the transmission shaft 208 to rotate through the transmission belt 204. At the same time, the transmission shaft 208 drives the scraper 207 to move on the inner wall of the filter 206, and the attachments on the inner wall of the filter 206 are scraped off, and the spiral structure of the scraper 207 is used to push the attachments to the sewage pipe 202. The sealing plug 201 is rotated to open the sewage pipe 202, and the attachments inside the filter 206 can be discharged, completing the separation of solid components in the sewage.
