Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically, to a wastewater treatment device that efficiently utilizes photocatalysts. Background Technology

[0002] In real life, various chemical plants, foundries, and other manufacturing sites generate wastewater containing certain harmful chemicals during their daily production processes. Because these chemicals can damage the environment, wastewater treatment is necessary before recycling or discharging it. While there are various existing wastewater treatment methods, the treatment of wastewater containing harmful chemicals requires the use of targeted catalysts. By adding wastewater and catalysts to an environment suitable for the catalyst's effectiveness—such as appropriate temperature, light intensity, and oxygen content—the catalyst can quickly take effect. Through the principle of oxidation-reduction, the corresponding chemical components in the wastewater undergo separation and degradation, facilitating more detailed purification treatment in subsequent processes.

[0003] The catalysts commonly used in existing technologies are photocatalysts. These are added to wastewater and exposed to sufficient light to generate active species within the photocatalyst. However, the wastewater treatment capacity of existing equipment generally corresponds to the highest actual wastewater discharge from the factory. Since the discharge volume is not always at its maximum, there is often unused space within the equipment during normal operation. Because sufficient light is a prerequisite for photocatalyst effectiveness, some lighting equipment remains idle when wastewater treatment is being performed in a particular area. Furthermore, existing wastewater treatment equipment using photocatalysts struggles to concentrate all available light resources to adequately illuminate the photocatalyst, thus affecting its wastewater treatment efficiency. Summary of the Invention

[0004] This invention proposes a wastewater treatment device that efficiently utilizes photocatalysts, solving the problem in the prior art where it is difficult to fully utilize excess light resources within the wastewater treatment equipment when performing wastewater treatment operations in certain areas, thus affecting the efficiency of photocatalysts in wastewater treatment.

[0005] The technical solution of the present invention is as follows: A wastewater treatment device that efficiently utilizes a photocatalyst includes a treatment tank, wherein multiple treatment tanks are arranged on both sides inside the treatment tank, and the multiple treatment tanks are grouped in pairs, and further includes:

[0006] A mobile trolley is movable and set on the top of the processing box. Each processing tank is equipped with a light-emitting component. A fixed horizontal plate is set on the top of the light-emitting component. A positioning and installation component is set between the fixed horizontal plate and the processing tank. Two meshing inserts are fixedly connected through the middle of the fixed horizontal plate.

[0007] The clamping rods are set to a quantity of four and are arranged in pairs. The clamping rods are clamped in conjunction with the inner wall of the engaging insert.

[0008] The number of lifting frames is set to two and fixedly connected to the top of the mobile trolley on both sides respectively. Each side of the lifting frame is slidably provided with a sliding seat whose longitudinal position can be adjusted sequentially. A spacing adjustment mechanism is provided between the two clamping rods and one of the sliding seats.

[0009] To facilitate the discharge of wastewater and catalyst from the treatment tank, the bottom of the treatment tank is recessed, making the bottom sides of the treatment tank funnel-shaped. The bottom of the treatment tank fits against the bottom side wall of the treatment tank, and a drain valve pipe is connected to the bottom of the treatment tank.

[0010] To enable the mobile trolley to move on top of the processing box, a sliding frame is further provided inside the processing box. Sliding chambers are provided on both sides of the sliding frame, and sliding tracks are provided on the upper and lower sides of the sliding chambers. Moving wheels are driven by a power drive device on both sides of the mobile trolley, and the moving wheels are driven within the two sliding tracks. A support slot is fixedly connected to the middle of the sliding frame, and the middle of the mobile trolley is slidably mounted on the support slot.

[0011] To provide sufficient illumination to the wastewater and photocatalyst in the treatment tank, the illumination assembly further includes a curved transparent cylinder and light sources. The curved transparent cylinder is fixedly connected to the bottom of the fixed horizontal plate, and multiple light sources are disposed inside the curved transparent cylinder.

[0012] In order to maintain engagement between the clamping rod and the engaging cylinder, a concave engaging clamp is fixedly connected to one side of the inner wall of the engaging cylinder, and a plurality of engaging blocks that contact the inner and outer walls of the concave engaging clamp are fixedly connected to the bottom of the clamping rod.

[0013] To adjust the positions of the two sliding seats sequentially, a sliding groove frame is longitudinally slidably connected inside the lifting frame. A screw drive mechanism is installed inside the lifting frame. The sliding groove frame is threadedly connected to the screw drive mechanism. An engaging connection assembly is provided between the sliding groove frame and the sliding seat. Iron slide bars are provided on both sides of the lifting frame. An electromagnet is provided on the sliding seat and magnetically connected to the iron slide bars, so that the sliding seat is locked on the lifting frame.

[0014] To keep the light-emitting components fixed within the processing tank, the positioning and mounting assembly further includes a positioning plate and a meshing toothed plate, multiple of which are fixedly connected to the top of the processing tank. Multiple meshing seats are fixedly connected at equal intervals to the top of the positioning plate, multiple of which are fixedly connected to the bottom of the fixed horizontal plate. The meshing toothed plate meshes with the meshing seats.

[0015] To adjust the spacing between the two clamping rods and enable them to engage with the fixed cross plate, the spacing adjustment mechanism further includes an adjusting slot frame, a sloped component, and a sloped extrusion ring, all fixedly connected to a sliding seat. The adjusting slot frame has adjusting chambers on both sides. The top of each clamping rod is slidably connected to one of these chambers. A spring damper is provided between the top of the clamping rod and the inner wall of the adjusting chamber. The sloped component is fixedly connected to the opposite sides of each of the two clamping rods. The bottom arc surface of the sloped extrusion ring contacts the outer walls of the two sloped components. A drive electric cylinder is located in the middle of the adjusting slot frame, and the output end of the drive electric cylinder is fixedly connected to the top of the adjusting slot frame.

[0016] To further add photocatalyst into the treatment tank, the mobile trolley is fixedly connected to an installation frame. The bottom of the installation frame is connected to multiple discharge hoppers. The bottom of each discharge hopper is connected to a telescopic hose for discharging the photocatalyst. The positioning plate is located between two of the telescopic hoses. A connecting frame is fixedly connected between the multiple telescopic hoses. A bent connector is fixedly connected between the connecting frame and two sliding seats located on the same side.

[0017] To further add photocatalysts into the multiple discharge hoppers, the mounting frame is provided with a catalyst feeding mechanism for adding photocatalysts into the multiple discharge hoppers.

[0018] The working principle and beneficial effects of this invention are as follows:

[0019] In this invention, when only a few treatment tanks and photocatalysts are used to treat wastewater, in order to make full use of sufficient light resources, a moving trolley is moved within a sliding frame. The trolley's position is adjusted via a spacing adjustment mechanism, moving two clamping rods to the upper side of an idle light-emitting component. The clamping rods are then moved into the engaging cylinder, and the spacing between them is adjusted. After the two clamping rods engage with the fixed horizontal plate, the light-emitting component is lifted from the treatment tank by a screw drive mechanism and moved to another treatment tank. This results in multiple light-emitting components in the treatment tank where wastewater treatment is about to begin. When using a single light-emitting component in the treatment tank, it is positioned in the center using a positioning mounting component. When multiple light-emitting components need to be moved into the treatment tank, they are equidistantly arranged within the tank. This method not only improves the reaction efficiency and effect of the photocatalyst in the treatment tank but also ensures sufficient light illumination for the photocatalyst even when the wastewater concentration results in insufficient light transmittance.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1 to 2As shown, this embodiment proposes a wastewater treatment device that efficiently utilizes photocatalysts. It includes a treatment tank 1, with multiple treatment tanks 2 arranged on both sides of the tank's interior. The treatment tanks 2 are grouped in pairs. The bottom of the treatment tank 1 is recessed, making the bottom sides of the tank 1 funnel-shaped. The bottom of the treatment tanks 2 fits against the bottom sidewall of the treatment tank 1. A drain valve pipe 9 connects to the bottom of the treatment tanks 2. By improving the shape of the treatment tank 1 and treatment tanks 2, the bottom area of ​​the treatment tanks 2 is reduced during wastewater discharge, making it easier for the treated wastewater to be discharged through the drain valve pipe 9. During wastewater discharge, the photocatalyst is also discharged along with the wastewater. Because the photocatalyst particles are small, they tend to remain at the bottom of the treatment tanks 2 after wastewater discharge. Reducing the bottom area of ​​the treatment tanks 2 makes the photocatalyst retention more concentrated, facilitating cleaning by users.

[0034] like Figures 1 to 2 and Figure 5 As shown, it also includes a mobile trolley 3, which is movably mounted on top of the processing box 1. A sliding frame 10 is installed inside the processing box 1. Sliding chambers are provided on both sides of the sliding frame 10, and sliding tracks 11 are provided on the upper and lower sides of each sliding chamber. Moving wheels 13 are driven by a power drive device 12 on both sides of the mobile trolley 3. The moving wheels 13 are driven within the two sliding tracks 11. A support frame 14 is fixedly connected to the middle of the sliding frame 10, and the middle of the mobile trolley 3 is slidably mounted on the support frame 14. Moving wheels 13 are driven by a power drive device 12 on both sides of the mobile trolley 3. The transmission is equipped with multiple moving wheels 13. The power drive device 12 is a common power device in the prior art that uses electricity as the driving energy. It is a prior art device known to those skilled in the art. The power drive device 12 can drive the moving wheels 13 on both sides, so that the moving trolley 3 can move laterally on the sliding frame 10 and move along the moving path of the two sliding tracks 11. The moving trolley 3 has slots for the fixed horizontal plate 4 and the lighting component 100 to enter, and also has through slots for the multiple telescopic hoses 32 to descend.

[0035] like Figures 1 to 3As shown, each treatment tank 2 is equipped with a lighting component 100. A fixed horizontal plate 4 is provided on the top of the lighting component 100. The lighting component 100 includes a curved transparent cylinder 15 and a light source 16. The curved transparent cylinder 15 is fixedly connected to the bottom of the fixed horizontal plate 4. Multiple light sources 16 are provided inside the curved transparent cylinder 15. The curvature and shape of the curved transparent cylinder 15 correspond to the shape of the inner side wall of the treatment tank 2, ensuring that the light source 16 fully illuminates the area inside the treatment tank 2 when it emits light. The light source 16 is a common technical device for illuminating photocatalysts in the prior art. It is a prior art device known to those skilled in the art. The use of the light source 16 in the prior art also includes immersing it inside the sewage. However, in this invention, the movement of the lighting component 100 is only lifting and lateral movement, and there is no impact on the wiring of the lighting component 100.

Multiple meshing seats 23 are fixedly connected at equal intervals to the top of the positioning plates 22. The number of meshing toothed plates 24 is set to multiple and fixedly connected to the bottom of the fixed horizontal plate 4. The meshing toothed plate 24 meshes with the meshing seat 23. When it is necessary to keep the fixed horizontal plate 4 and the illumination component 100 stable in the processing tank 2, when the fixed horizontal plate 4 and the illumination component 100 are moved, the multiple meshing toothed plates 24 on the fixed horizontal plate 4 mesh with one of the meshing seats 23 on the multiple positioning plates 22, so that the fixed horizontal plate 4 is fixed between the multiple positioning plates 22.

[0037] like Figures 1 to 7 As shown, two meshing cylinders 5 are fixedly connected through the middle of the fixed horizontal plate 4. The number of clamping rods 6 is set to four and arranged in pairs. The clamping rods 6 are clamped in cooperation with the inner wall of the meshing cylinders 5. A concave meshing clamp 17 is fixedly connected to one side of the inner wall of the meshing cylinder 5. Multiple meshing blocks 18 that contact the inner and outer walls of the concave meshing clamp 17 are fixedly connected to the bottom of the clamping rods 6. In order to move the fixed horizontal plate 4 and the lighting component 100, the bottom of the two clamping rods 6 is moved into the corresponding meshing cylinders 5 by the sliding seat 8. By adjusting the distance between the two clamping rods 6, the multiple meshing blocks 18 at the bottom of the clamping rods 6 contact the inner and outer walls of the concave meshing clamp 17, so that the fixed horizontal plate 4 and the two clamping rods 6 are kept in meshing connection.

[0038] like Figures 1 to 2 and Figures 5 to 8As shown, there are two lifting frames 7, which are fixedly connected to the top of the mobile trolley 3 on both sides. Each side of the lifting frame 7 is slidably provided with a sliding seat 8 that can be adjusted longitudinally. A sliding groove frame 19 is slidably connected in the longitudinal direction inside the lifting frame 7. A screw transmission mechanism is provided inside the lifting frame 7. The screw transmission mechanism includes a transmission screw 34, which is rotatably connected inside the lifting frame 7. A first drive motor 35 is provided at the top of the lifting frame 7. The output end of the first drive motor 35 is fixedly connected to the transmission screw 34. When it is necessary to drive the sliding groove frame 19 to move longitudinally, the first drive motor 35 is started to drive the transmission screw 34 to rotate, so that the sliding groove frame 19 moves longitudinally inside the lifting frame 7.

[0039] The sliding slot frame 19 is threadedly connected to the lead screw transmission mechanism. A meshing connection assembly is provided between the sliding slot frame 19 and the sliding seat 8. The meshing connection assembly includes a T-shaped slide bar 36. The T-shaped slide bar 36 is fixedly connected to the inner top wall of the sliding slot frame 19. A meshing insert rod 37 is slidably connected to the T-shaped slide bar 36. A meshing slot 38 is provided on the sliding seat 8. An internal toothed groove 39 is provided at the bottom of the meshing insert rod 37. A transmission gear 40 meshes with the internal toothed groove 39. A second drive motor 41 is provided inside the sliding slot frame 19, and the transmission gear 40 is located within the second drive motor 41. At the output end, when the sliding slot frame 19 moves longitudinally so that the position of the engaging rod 37 corresponds to that of the engaging slot 38, the second drive motor 41 is started to drive the transmission gear 40 to rotate. Through the meshing relationship between the transmission gear 40 and the internal tooth groove 39, the engaging rod 37 is driven to slide on the T-shaped slide bar 36, so that the engaging rod 37 enters the engaging slot 38, and the sliding slot frame 19 is engaged with the sliding seat 8 on one side. During the subsequent longitudinal movement of the flower bed slot frame, the sliding seat 8 and the components connected to it are driven to move longitudinally together.

[0040] Iron slide bars 20 are provided on both sides of the lifting frame 7. An electromagnet 21 is provided on the sliding seat 8 and is magnetically connected to the iron slide bars 20, so that the sliding seat 8 is locked on the lifting frame 7. When the sliding slot frame 19 is engaged with one of the sliding seats 8, the other sliding seat 8 is kept stationary on the lifting frame 7 through the magnetic connection between the electromagnet 21 and the iron slide bars 20.

[0041] like Figures 1 to 2 and Figures 5 to 8As shown, a spacing adjustment mechanism 300 is provided between the two clamping rods 6 and one of the sliding seats 8. The spacing adjustment mechanism 300 includes a spacing adjustment slot frame 25, a slope member 27, and a slope extrusion ring 28, which are fixedly connected to the sliding seat 8. A spacing adjustment chamber is provided on both sides of the spacing adjustment slot frame 25. The top of the clamping rod 6 is slidably connected to the spacing adjustment chamber. A spring damper 26 is provided between the top of the clamping rod 6 and the inner wall of the spacing adjustment chamber. A slope member 27 is fixedly connected to the opposite sides of the two clamping rods 6. The bottom arc surface of the slope extrusion ring 28 is connected to the two... The outer wall of the sloped part 27 contacts the center of the adjustable spacing slot 25, where a drive electric cylinder 29 is provided. The output end of the drive electric cylinder 29 is fixedly connected to the top of the adjustable spacing slot 25. After the bottom of the clamping rod 6 is moved into the meshing cylinder 5, the drive electric cylinder 29 is activated to drive the slope extrusion ring 28 to descend. The slope extrusion ring 28 contacts the inclined side wall of the sloped part 27, extruding the tops of the two clamping rods 6 to move laterally in the adjustable spacing chamber, adjusting the distance between the two clamping rods 6, so that the meshing block 18 and the concave meshing clamp 17 remain engaged.

[0042] like Figures 1 to 2 , Figure 5 and Figure 9 As shown, a mounting frame 30 is fixedly connected to the mobile trolley 3. Multiple discharge hoppers 31 are connected to the bottom of the mounting frame 30. Telescopic hoses 32 for discharging photocatalyst are connected to the bottom of the discharge hoppers 31. A positioning plate 22 is located between two telescopic hoses 32. A connecting frame 33 is fixedly connected between the multiple telescopic hoses 32. A bent connector is fixedly connected between the connecting frame 33 and two sliding seats 8 located on the same side. When it is necessary to add photocatalyst to the treatment tank 2, the photocatalyst is first discharged into the multiple discharge hoppers 31 and then discharged through the telescopic hoses 32. In order to reduce the discharge height of the photocatalyst and ensure the uniformity of the photocatalyst, the sliding tank frame 19 is used to drive the sliding seat 8 to descend, so that the sliding seat 8 drives the bent connector and the connecting frame 33 to descend together, and finally the bottom of the telescopic hose 32 extends into the treatment tank 2.

[0043] The mounting frame 30 is equipped with a catalyst feeding mechanism for adding photocatalysts into multiple discharge hoppers 31. The catalyst feeding mechanism includes a suction device 42, which is mounted on the mounting frame 30. The mounting frame 30 is also equipped with a screw conveyor 43. The suction device 42 is connected to the screw conveyor 43. Multiple discharge valve pipes 44 are connected to the screw conveyor 43. The discharge ends of the discharge valve pipes 44 and the screw conveyor 43 correspond to the multiple discharge hoppers 31. Both the suction device 42 and the screw conveyor 43 are common prior art devices used for conveying small particulate materials, and are also common conveying devices for photocatalysts. They are prior art devices known to those skilled in the art. In actual use, the suction device 42 and the screw conveyor 43 respectively convey photocatalysts into the multiple discharge hoppers 31.

[0044] The working principle of this highly efficient wastewater treatment device utilizing photocatalysts:

[0045] After determining the number of processing tanks 2 to be used, the moving trolley 3 is moved to move the support rod to the top of the idle lighting component 100. The first drive motor 35 is started to drive the transmission screw 34 to rotate, causing the sliding slot frame 19 to move longitudinally within the lifting frame 7. The sliding slot frame 19 is moved to the position of the sliding seat 8 on the side corresponding to the support rod, so that the engaging rod 37 slidably connected on the sliding slot frame 19 corresponds to the engaging slot 38. After the engaging rod 37 is moved into the engaging slot 38, the sliding slot frame 19 and the sliding seat 8 are engaged. Then, the sliding slot frame 19 and the sliding seat 8 are moved longitudinally to move the clamping rod 6 into the engaging cylinder 5. The drive electric cylinder 2 is then started. 9 drives the slope extrusion ring 28 down, and the slope extrusion ring 28 contacts the inclined side wall of the slope part 27, extruding the top of the two clamping rods 6 to move laterally in the adjustment chamber, adjusting the distance between the two clamping rods 6, so that the meshing block 18 and the concave meshing clamp 17 are engaged, and then drives the sliding seat 8 to move upward, moving the fixed horizontal plate 4 and the lighting component 100 out of the processing tank 2. Then, the moving trolley 3 is used to move the fixed horizontal plate 4 and the lighting component 100 to the required processing box 1, and the fixed horizontal plate 4 is moved between the multiple positioning plates 22 in the processing tank 2 to position the lighting component 100 in the processing tank 2.

[0046] Then, the photocatalyst is conveyed into multiple discharge hoppers 31 through the suction device 42 and the screw conveyor 43 respectively. The height of another sliding seat 8 is adjusted so that the bottom of the telescopic hose 32 extends into the treatment tank 2. During the slow movement of the moving trolley 3, the photocatalyst is evenly added into the treatment tank 2. Then, during the process of adding the photocatalyst, the wastewater to be treated is also added into the treatment tank 2 so that the photocatalyst and wastewater are mixed and the photocatalyst is suspended in the wastewater. Finally, the light component 100 is used in conjunction with the photocatalyst to treat the wastewater.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
