Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and specifically to a photovoltaic wastewater treatment device. Background Technology

[0002] Photovoltaic wastewater contains a large amount of heavy metal pollutants. Direct discharge of untreated wastewater will pollute water bodies, affect water quality safety, and thus pose a threat to the ecological environment and human health. The use of wastewater treatment devices can reduce harmful substances in wastewater and protect water resources and the ecological environment.

[0003] In the wastewater treatment process, adding coagulants or flocculants to the wastewater can promote the coagulation of fine particles or colloidal particles into larger particles and accelerate sedimentation. The sediment will fall to the bottom of the wastewater treatment tank. In the existing technology, during the discharge of sediment impurities from the bottom of the wastewater treatment tank, a large amount of untreated wastewater may be discharged at the same time as the sediment impurities. This requires the wastewater to be recycled and treated again, which will prolong the entire wastewater treatment process and reduce the treatment efficiency accordingly, affecting the overall operating efficiency and treatment capacity of the wastewater treatment facility.

[0004] Therefore, it is necessary to invent a photovoltaic wastewater treatment device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a photovoltaic wastewater treatment device that, through the combined use of primary and secondary sealing, ensures the complete sealing of the settling funnel, preventing waste liquid leakage. By guiding the flow of waste liquid through a one-way valve, the content of waste liquid at the bottom of the settling funnel is reduced. During the discharge of wastewater sedimentation, the device aims to reduce excess wastewater discharge and improve the efficiency and quality of waste liquid treatment.

The secondary adjustment device also includes a locking block installed on the top of a rectangular pressing plate, and the elastic ejector block can engage with the locking block.

[0011] When the primary sealing plate is separated from the settling funnel and the adjusting rack is located at the top of the rotating gear, the elastic ejector block and the locking block are in a locked state.

[0012] When the sealing plate and the settling funnel are in contact, and the adjusting rack and the rotating gear are engaged, the rotating gear rotates counterclockwise, and the elastic ejector block separates from the locking block.

[0013] As a preferred embodiment of a photovoltaic wastewater treatment device, the secondary adjustment device further includes a guide column and a reset spring. The secondary pressing device also includes a U-shaped adjustment plate slidably disposed on the top of the primary sealing plate. The inner side of the rectangular pressing plate is provided with a transverse through groove for the U-shaped adjustment plate to slide laterally. The guide column is fixedly installed on the top of the rectangular pressing plate, and the top of the guide column extends through and to the top of the bottom connecting plate. The locking block is fixedly disposed on the top of the guide column. The reset spring is sleeved on the outer side of the guide column and is located at the bottom end of the locking block and the top end of the bottom connecting plate. The adjusting rack is fixedly installed on the top of the rectangular pressing plate and is disposed on one side of the rotating gear. The bottom end of the adjusting rack is slidably connected to the bottom connecting plate.

[0014] As a preferred embodiment of a photovoltaic wastewater treatment device, the stirring device further includes a feeding pipe, a driven gear ring, and a second rotating motor. The feeding pipe is equipped with multiple liquid distribution pipes for stirring. The feeding pipe is rotatably installed inside the wastewater treatment tank, with one end extending to the outside of the wastewater treatment tank. The driven gear ring is sleeved on both sides of the feeding pipe located on the inner wall of the wastewater treatment tank. The driven gear ring meshes with the second rotating gear. The gear shaft of the second rotating gear extends to the outside of the wastewater treatment tank and is connected to the output end of the second rotating motor.

[0015] As a preferred embodiment of a photovoltaic wastewater treatment device, the position adjustment device further includes a horizontal slider, a rotating gear, and a rotating motor. The horizontal slider slides laterally along a guide rod, and the top end of the horizontal slider is fixedly connected to the telescopic end of the electric telescopic rod. The horizontal guide device also includes a bottom rack located at the bottom end of the guide rod. The rotating gear is located at the bottom end of the horizontal slider, and the rotating gear meshes with the bottom rack. The rotating motor is fixedly installed on the outside of the horizontal slider, and the output end of the rotating motor is fixedly connected to the rotating gear.

[0016] As a preferred embodiment of a photovoltaic wastewater treatment device, the secondary pressing device further includes multiple guide pressing rods. The top end of each guide pressing rod is fixedly connected to a U-shaped adjustment plate, and the bottom end of each guide pressing rod is fixedly connected to a secondary sealing plate. The multiple guide pressing rods are slidably connected to a primary sealing plate.

[0017] As a preferred embodiment of a photovoltaic wastewater treatment device, the side wall of the wastewater treatment tank is provided with an inlet for inputting wastewater and an outlet for outputting wastewater after sedimentation.

[0018] As a preferred embodiment of a photovoltaic wastewater treatment device, the inner side of the settling funnel is inverted trapezoidal, and a bracket for supporting the wastewater treatment tank is fixedly installed on the outer side of the settling funnel.

[0019] As a preferred embodiment of a photovoltaic wastewater treatment device, the feeding pipe is connected to a dosing system for adding reactive materials inside the wastewater treatment tank.

[0020] The beneficial effects of this invention are as follows: By rotating the first motor, the horizontal slider slides along the guide rod, allowing the primary sealing plate to remain at the top of the preset settling funnel. The connecting frame slides downwards via the electric telescopic rod, enabling the primary sealing plate to accurately perform the initial seal on the settling funnel within the preset compartment. After the initial seal is completed, rotating the second gear on both sides drives the adjusting rack to slide longitudinally, causing the rectangular pressing plate to drive the U-shaped adjusting plate to slide longitudinally. This allows for a secondary seal after the initial seal is completed, achieved by the secondary sealing plate sliding downwards. During the downward sliding of the secondary sealing plate… Waste liquid in the upper part of the settling funnel flows into the top of the secondary sealing plate through a one-way valve, reducing the waste liquid content at the bottom of the settling funnel cavity. This reduces the amount of excess wastewater discharged when the discharge valve is opened to release the sediment. The combination of primary and secondary sealing ensures complete sealing of the settling funnel, preventing waste liquid leakage. The design of the secondary sealing plate not only enhances the sealing effect but also guides the flow of waste liquid through the one-way valve, reducing the amount of waste liquid at the bottom of the settling funnel. This reduces the amount of excess wastewater discharged when releasing the sediment, improving the efficiency and quality of waste liquid treatment. Attached Figure Description

[0046] refer to Figures 1 to 12This invention provides a photovoltaic wastewater treatment device, including a wastewater treatment tank 1. The bottom of the wastewater treatment tank 1 is provided with multiple settling funnels 6, each divided into individual compartments. The bottom ends of each settling funnel 6 are connected to a discharge valve 7 via pipes. The top of the wastewater treatment tank 1 is provided with a transverse guide device 2, which includes a guide rod 201 arranged transversely. A position adjustment device 4 is slidably arranged on the outer side of the guide rod 201. The position adjustment device 4 includes an electric telescopic rod 402 for adjusting the longitudinal height. A primary pressing device 3 is fixedly connected to the bottom end of the electric telescopic rod 402. The primary pressing device 3 includes a connecting frame 301. A primary sealing plate 9 for sealing a single settling funnel 6 is fixedly connected to the bottom end of the connecting frame 301. A secondary pressing device 11, which slides longitudinally, is provided at the top end of the primary sealing plate 9. The secondary pressing device 11 includes a component for extending to… The sedimentation funnel 6 has a secondary sealing plate 1103 inside. The primary pressing device 3 also includes a synchronous guide block 302. A synchronous adjustment device 8 is slidably arranged inside the synchronous guide block 302. The synchronous guide block 302 is used to drive the synchronous adjustment device 8 to slide longitudinally. The synchronous adjustment device 8 includes a bottom connecting plate 804 located at its bottom end. A secondary adjustment device 10 that can slide longitudinally is arranged at the bottom end of the bottom connecting plate 804. The secondary adjustment device 10 includes a rectangular pressing plate 1006 and an adjusting rack 1004. The rectangular pressing plate 1006 is used to drive the secondary pressing device 11 to slide longitudinally. The wastewater treatment tank 1 is equipped with a stirring device 5 inside. The stirring device 5 includes a rotating gear 504. The rotating gear 504 can mesh with the adjusting rack 1004. Multiple one-way valves 12 are arranged at the bottom ends of both the primary sealing plate 9 and the secondary sealing plate 1103.

[0047] When the primary sealing plate 9 is separated from the settling funnel 6, the adjusting rack 1004 moves away from the rotating gear 504.

[0048] When the primary sealing plate 9 and the settling funnel 6 are in contact, the adjusting rack 1004 meshes with the rotating gear 504.

[0049] When the primary sealing plate 9 is separated from the settling funnel 6, the elastic ejector block 802 engages with the locking block 1002. Without external force, the secondary adjustment device 10 and the synchronous adjustment device 8 can slide synchronously with the primary pressing device 3. The rotating gear 504 cannot contact the adjusting rack 1004, so that the primary pressing device 3 will not interfere with the settling funnel 6 when adjusting its position. When the primary sealing plate 9 is in contact with the settling funnel 6, the rotating gear 504 engages with the adjusting rack 1004. When the rotating gear 504 rotates counterclockwise, the adjusting rack 1004 slides downward, and the elastic ejector block 802 separates from the locking block 1002 under external force. The secondary sealing plate 1103 extends into the settling funnel 6, discharging excess wastewater and improving treatment efficiency.

[0050] The synchronous adjustment device 8 further includes a longitudinal sliding plate 801, an elastic ejector block 802, a telescopic spring 803, and a transverse connecting rod 805. Multiple longitudinal guide blocks 102 are fixedly installed on the inner wall of the wastewater treatment tank 1. The longitudinal sliding plate 801 is located inside the longitudinal guide block 102 and forms a sliding connection with it. The top end of the longitudinal sliding plate 801 is fixedly connected to the transverse connecting rod 805, and the bottom end of the longitudinal sliding plate 801 is fixedly connected to the bottom connecting plate 804. The transverse connecting rod 805 forms a sliding connection with the synchronous guide block 302. The elastic ejector block 802 is located inside the longitudinal sliding plate 801, and the end of the elastic ejector block 802 is fixedly connected to one end of the telescopic spring 803. The secondary adjustment device 10 further includes a locking block 1002 installed on the top of the rectangular pressing plate 1006. The elastic ejector block 802 can engage with the locking block 1002.

[0051] When the primary sealing plate 9 is separated from the settling funnel 6, and the adjusting rack 1004 is located at the top of the rotating gear 504, the elastic ejector block 802 and the locking block 1002 are in a locked state.

[0052] When the primary sealing plate 9 and the settling funnel 6 are in contact, and the adjusting rack 1004 is engaged with the rotating gear 504, the rotating gear 504 rotates counterclockwise, and the elastic ejector block 802 separates from the locking block 1002.

[0053] After the wastewater sedimentation and discharge are completed, the clockwise rotation of the second gear 504, under the action of the return spring 1003, causes the adjusting rack 1004 to mesh with the second gear 504, causing the secondary adjustment device 10 to slide upward. The locking block 1002 slides upward and engages with the elastic ejector block 802. At this time, the bottom connecting plate 804 is in contact with the rectangular pressing plate 1006, and the secondary sealing plate 1103 is in contact with the primary sealing plate 9. The primary sealing plate 9 is lifted away from the settling funnel 6 by the electric telescopic rod 402. The combination of the return spring 1003 and the adjusting rack 1004 makes it easier to achieve secondary ejection and reset after ejection, making the secondary ejection and reset process simpler and more efficient. This reduces the complexity of manual operation and improves the automation level of the equipment.

[0054] The secondary adjustment device 10 further includes a guide post 1001 and a reset spring 1003. The secondary pressing device 11 further includes a U-shaped adjustment plate 1101 slidably disposed on the top of the primary sealing plate 9. The inner side of the rectangular pressing plate 1006 is provided with a transverse through groove 1005 for the U-shaped adjustment plate 1101 to slide laterally. The guide post 1001 is fixedly installed on the top of the rectangular pressing plate 1006. The top of the guide post 1001 extends through and to the top of the bottom connecting plate 804. The locking block 1002 is fixedly disposed on the top of the guide post 1001. The reset spring 1003 is sleeved on the outer side of the guide post 1001 and is located at the bottom end of the locking block 1002 and the top end of the bottom connecting plate 804. The adjusting rack 1004 is fixedly installed on the top of the rectangular pressing plate 1006 and disposed on one side of the rotating gear 504. The bottom end of the adjusting rack 1004 is slidably connected to the bottom connecting plate 804. The design of the U-shaped adjustment plate 1101 and the rectangular pressing plate 1006 ensures that while the position adjustment device 4 slides laterally, the U-shaped adjustment plate 1101 can slide synchronously along the transverse through groove 1005. The transverse through groove 1005 can drive the U-shaped adjustment plate 1101 to slide back and forth longitudinally, which facilitates the reset of the secondary sealing plate 1103.

[0055] The stirring device 5 also includes a feeding pipe 501, a driven gear ring 502, and a second rotating motor 503. The feeding pipe 501 is provided with multiple liquid distribution pipes for stirring. The feeding pipe 501 is rotatably installed inside the wastewater treatment tank 1. One end of the feeding pipe 501 extends to the outside of the wastewater treatment tank 1. The driven gear ring 502 is sleeved on both sides of the feeding pipe 501 located on the inner wall of the wastewater treatment tank 1. The driven gear ring 502 is meshed with the second rotating gear 504. The gear shaft of the second rotating gear 504 extends to the outside of the wastewater treatment tank 1 and is connected to the output end of the second rotating motor 503. When the primary sealing plate 9 is separated from the settling funnel 6, the rotation of the second rotating gear 504 can drive the feeding pipe 501 to rotate, thereby stirring the waste liquid inside the wastewater treatment tank 1 without interfering with the internal structure of the wastewater treatment tank 1. At the same time, the rotation of the feeding pipe 501 can drive the second rotating gear 504 on both sides to rotate synchronously, so that the secondary adjustment device 10 can slide synchronously, improving the transmission effect.

[0056] The position adjustment device 4 further includes a horizontal slider 401, a rotating gear 403, and a rotating motor 404. The horizontal slider 401 slides laterally along the guide rod 201, and its top end is fixedly connected to the telescopic end of the electric telescopic rod 402. The horizontal guide device 2 also includes a bottom rack 202 located at the bottom end of the guide rod 201. The rotating gear 403 is located at the bottom end of the horizontal slider 401, and it meshes with the bottom rack 202. The rotating motor 404 is fixedly installed on the outside of the horizontal slider 401, and its output end is fixedly connected to the rotating gear 403. The electric telescopic rod 402 can drive the connecting frame 301 to slide longitudinally by extending and retracting. The rotating motor 404 can drive the rotating gear 403 to rotate, thereby driving the horizontal slider 401 and the connecting frame 301 to slide along the length of the bottom rack 202. This improves the flexibility of the device, and since the transmission devices are all located above the wastewater treatment tank 1, they will not be corroded by wastewater, extending the service life of the equipment.

[0057] The secondary pressing device 11 also includes multiple guide pressing rods 1102. The top end of each guide pressing rod 1102 is fixedly connected to the U-shaped adjusting plate 1101, and the bottom end of each guide pressing rod 1102 is fixedly connected to the secondary sealing plate 1103. The multiple guide pressing rods 1102 are slidably connected to the primary sealing plate 9. The guide pressing rods 1102 prevent the secondary sealing plate 1103 from shifting or tilting during movement, providing additional support and guidance. A sealing ring is provided on the outer side of the secondary sealing plate 1103 to enhance the sealing effect.

[0058] The wastewater treatment tank 1 has an inlet 103 for inputting wastewater and an outlet 101 for outputting settled wastewater on its side wall. The inner side of the settling funnel 6 is inverted trapezoidal, and a support bracket for supporting the wastewater treatment tank 1 is fixedly installed on the outer side of the settling funnel 6. The feeding pipe 501 is connected to the dosing system for adding reactive materials inside the wastewater treatment tank 1. By connecting the feeding pipe 501 to the dosing system, reactive materials can be added while the internal waste liquid is being stirred, allowing the reactive materials to be evenly dispersed inside the wastewater treatment tank 1, improving the reaction effect, increasing treatment efficiency, and reducing treatment time and energy consumption.

[0059] This invention utilizes a rotating motor 404 to drive a horizontal slider 401 to slide along a guide rod 201, allowing the primary sealing plate 9 to remain at the top of a preset settling funnel 6. The electric telescopic rod 402 controls the connecting frame 301 to slide downwards, enabling the primary sealing plate 9 to accurately perform an initial seal on the settling funnel 6 within the preset compartment. After the initial seal is completed, rotating gears 504 on both sides drive the adjusting rack 1004 to slide longitudinally, causing the rectangular pressing plate 1006 to drive the U-shaped adjusting plate 1101 to slide longitudinally. This allows for a secondary seal after the initial seal is completed, achieved by the secondary sealing plate 1103 sliding downwards. During the downward sliding process, the waste liquid in the upper part of the internal cavity of the settling funnel 6 flows into the top of the secondary sealing plate 1103 through the one-way valve 12, reducing the waste liquid content at the bottom of the settling funnel 6 cavity. This reduces the amount of excess wastewater discharged when the discharge valve 7 is opened to discharge the wastewater sediment. The combined use of primary and secondary seals ensures the complete sealing of the settling funnel 6, preventing waste liquid leakage. The design of the secondary sealing plate 1103 not only enhances the sealing effect but also guides the flow of waste liquid through the one-way valve 12, reducing the amount of waste liquid at the bottom of the settling funnel 6. This reduces the amount of excess wastewater discharged when discharging the wastewater sediment, improving the efficiency and quality of waste liquid treatment.

[0060] It should be stated that the above-described specific embodiments are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to the present invention. However, such variations, as long as they do not depart from the spirit of the present invention, should be within the scope of protection of the present invention. Furthermore, some terminology used in this specification and claims is not limiting, but merely for ease of description.
