Description

Technical Field

[0001] This utility model relates to a sewage treatment device, and more particularly to a sewage treatment device that combines photovoltaic power generation for use in the field of sewage treatment. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly entering the daily lives of ordinary people. According to the source of wastewater, wastewater treatment is generally divided into industrial wastewater treatment and domestic wastewater treatment. In wastewater treatment, the aeration system is one of the indispensable systems in wastewater treatment equipment.

[0003] Wastewater treatment, as a typical energy-intensive industry, suffers from high energy consumption in its core processes such as aeration, sludge treatment, and pumping. In recent years, with the rapid development and continuous cost reduction of photovoltaic power generation technology, combining photovoltaic clean energy with wastewater treatment systems has become an effective way to solve the industry's high energy consumption problem. Chinese Patent Publication No. CN209844887U discloses a tracking solar photovoltaic power generation device. This utility model enables the photovoltaic panel to change its orientation according to the sun's position, avoiding the photovoltaic panel not receiving sunlight due to changes in the sun's position, and improving the sufficiency of the photovoltaic panel when receiving sunlight.

[0004] Generally, aeration is achieved by aerating the inside of the sewage tank through aeration pipes in the aeration system, thereby filling the sewage with oxygen and providing oxygen for aerobic microorganisms. However, current aeration pipes are usually installed in a fixed manner. For example, Chinese Patent Publication No. CN218321017U discloses an anti-clogging sewage treatment aeration tank. In this utility model, the inner walls of the front and rear ends of the aeration tank body are fixedly installed with uniformly distributed fixed pipes, and uniformly distributed aeration heads are fixedly installed on the fixed pipes.

[0005] The existing aeration pipes are fixed and can only oxygenate a local area of ​​the sewage tank. Because the bubbles generated by the aeration nozzles tend to accumulate around the pipes, and the water body also resists the gas, the dissolved oxygen concentration in areas far from the aeration pipes is insufficient, which limits the activity of aerobic microorganisms and ultimately affects the overall sewage treatment efficiency. Utility Model Content

[0006] The technical problem to be solved by this utility model in view of the above-mentioned prior art is that the aeration pipe in the sewage tank is installed in a fixed manner, which can only oxygenate a local area in the sewage tank, resulting in insufficient dissolved oxygen concentration in the area far away from the aeration pipe.

[0007] To address the aforementioned problems, this utility model provides a wastewater treatment device integrating photovoltaic power generation, comprising a wastewater tank, two drain pipes fixedly connected to the outer surface of the wastewater tank, and a cross-shaped mounting plate fixedly connected to the upper end of the wastewater tank. A column is rotatably inserted through the center of the mounting plate, and the lower end of the column is rotatably connected to the inner bottom wall of the wastewater tank. A motor is fixedly connected to the upper end of the mounting plate, and a drive gear is fixedly connected to the output end of the motor. A photovoltaic panel, a storage box, a driven gear, and a mounting block are fixedly connected sequentially from top to bottom on the outer surface of the column. The drive gear and the driven gear mesh. A solar tracking sensor is installed on the surface of the photovoltaic panel. The mounting block is located below the mounting plate, and multiple aeration pipes are arranged outside the mounting block. An oxygenation pump is fixedly connected to the lower end of the storage box, and an air inlet pipe is fixedly connected to the end of the oxygenation pump. The end of the air inlet pipe away from the oxygenation pump extends fixedly into the column and is fixedly connected to a positioning block. Multiple ventilation holes are drilled on the surfaces of both the positioning block and the column.

[0008] In the aforementioned wastewater treatment device that combines photovoltaic power generation with wastewater treatment, the positions of multiple aeration pipes are changed during the process of changing the position of the photovoltaic panels. This allows the aeration pipes to aerate different locations in the wastewater tank, effectively increasing the dissolved oxygen concentration in areas far from the aeration pipes. Consequently, the uniformity of dissolved oxygen distribution is improved, thus enhancing the wastewater treatment effect.

[0009] As a further supplement to this application, the outer surface of the positioning block is fixedly connected to the inner wall of the column, and the positioning block corresponds to the mounting block.

[0010] As a further supplement to this application, multiple aeration pipes are arranged in a ring array around the mounting block, and the aeration pipes are fixedly connected to the mounting block.

[0011] As a further supplement to this application, the aeration pipe is inclined and multiple nozzles are installed on the surface of the aeration pipe.

[0012] As a further supplement to this application, a flexible hose is fixedly connected between the aeration pipe and the mounting block, a cylinder is fixedly connected to the inner bottom wall of the column, a push block is fixedly connected to the upper end of the cylinder, and a push rod is rotatably connected to the end of the aeration pipe near the column. The push rod moves through the column and slides in contact with the push block.

[0013] As a further supplement to this application, the longitudinal section of the pusher is an isosceles trapezoid, and the solar tracking sensor, oxygen pump and cylinder are all connected to the signal of the external controller.

[0014] In summary, in practical applications, photovoltaic panels generate electricity to power electrical components. A solar tracking sensor monitors the position of sunlight in real time. When the sunlight's position changes, a motor is activated, driving the drive gear to rotate, which in turn rotates the driven gear and the column. The column then rotates the mounting block, causing the positions of multiple aeration pipes on the mounting block to change. Oxygen enters the positioning block through the air inlet pipe, passes through multiple vents into the mounting block, and then enters the aeration pipes, where it is aerated through the nozzles. As the aeration pipes change position, the aeration location changes, thus aerating different areas in the wastewater tank. This effectively increases the dissolved oxygen concentration in areas far from the aeration pipes, improving wastewater treatment efficiency. Attached Figure Description

Detailed Implementation

[0025] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0026] First implementation method:

[0027] Figures 1-3 The illustration shows a wastewater treatment device combining photovoltaic power generation, comprising a wastewater tank 1. Two drain pipes are fixedly connected to the outer surface of the wastewater tank 1, and electric valves can be installed on the drain pipes to facilitate the inflow and outflow of wastewater. A cross-shaped mounting plate 2 is fixedly connected to the upper end of the wastewater tank 1, providing a stable support platform. A column 3 is rotatably inserted through the center of the mounting plate 2, and the lower end of the column 3 is rotatably connected to the inner bottom wall of the wastewater tank 1. A motor 4 is fixedly connected to the upper end of the mounting plate 2. Those skilled in the art can select a suitable model of motor 4 according to actual needs, such as Y2-63M1-2-0.18KW. A drive gear 5 is fixedly connected to the output end of the motor 4. A photovoltaic panel 6, a storage box 7, a driven gear 8, and a mounting block 9 are fixedly connected sequentially from top to bottom on the outer surface of the column 3. The drive gear 5 and the driven gear 8 mesh with each other.

[0028] A solar tracking sensor 10 is installed on the surface of the photovoltaic panel 6. Those skilled in the art can select a suitable model of solar tracking sensor 10 according to actual needs, such as STR-21G. The storage box 7 can integrate electrical components for photovoltaic power generation and light tracking, such as inverters, batteries, and controllers, to form an existing photovoltaic power generation system. The controller is connected to the solar tracking sensor 10, motor 4, and oxygen pump 12 via cables. When the solar tracking sensor 10 senses a change in the position of sunlight, it will transmit the monitored information to the controller, which will then control the motor 4 to start, driving the drive gear 5 to rotate, thereby causing the driven gear 8 to drive the column 3 to rotate, causing the photovoltaic panel 6 to rotate. The inverter can convert the DC power generated by the photovoltaic panel 6 into AC power and store it in the battery for nighttime use. The structures of the inverter, battery, etc. are not shown in the figure. Since the photovoltaic power generation system is existing technology and this application does not involve any improvement to its principle, it will not be described in detail here.

[0029] Figures 3-6The diagram shows: Mounting block 9 is located below mounting plate 2. Multiple aeration pipes 11 are installed outside mounting block 9. An oxygenation pump 12 is fixedly connected to the lower end of storage tank 7. An air inlet pipe 13 is fixedly connected to the end of oxygenation pump 12. Column 3 is a hollow structure. The end of air inlet pipe 13 furthest from oxygenation pump 12 extends fixedly into column 3 and is fixedly connected to a positioning block 14. Multiple ventilation holes 15 are drilled on the surfaces of positioning block 14 and column 3. The ventilation holes 15 are equidistantly arranged along the column axis. The outer surface of positioning block 14 is fixedly connected to the inner wall of column 3. 4. Corresponding to the position of the mounting block 9, the mounting block 9 is also a hollow structure. Multiple aeration pipes 11 are arranged in a ring array around the mounting block 9. The aeration pipes 11 are fixedly connected to the mounting block 9. The aeration pipes 11 are set at an angle, and multiple nozzles are installed on the surface of the aeration pipes 11. When the oxygen pump 12 is turned on, oxygen can be discharged into the positioning block 14 through the air inlet pipe 13. Multiple air vents 15 facilitate the entry of oxygen into the mounting block 9, and then into the aeration pipes 11 for aeration through the nozzles. The air inlet pipe 13, the positioning block 14, the mounting block 9 and the aeration pipes 11 are connected.

[0030] When aerating wastewater, photovoltaic panels 6 generate electricity to power electrical components (such as motors 4 and oxygen pumps 12). Solar tracking sensors 10 can monitor the position of sunlight in real time. When the position of sunlight changes, motor 4 can be started to drive the drive gear 5 to rotate, causing the driven gear 8 and column 3 to rotate. Column 3 drives the mounting block 9 to rotate, thereby changing the position of multiple aeration pipes 11 on the mounting block 9. Oxygen enters the positioning block 14 through the air inlet pipe 13, passes through multiple vent holes 15 into the mounting block 9, and then enters the aeration pipes 11 to be aerated through the nozzles. As the position of the aeration pipes 11 changes, the aeration position changes, thereby aerating different positions in the wastewater tank 1, effectively increasing the dissolved oxygen concentration in areas far from the aeration pipes 11, and improving the wastewater treatment effect.

[0031] Second implementation method:

[0032] This embodiment adds a hose 16, a cylinder 17, a push block 18, and a push rod 19 to the first embodiment, while the rest remains the same as the first embodiment.

[0033] Figure 7 and Figure 8As shown: A hose 16 is fixedly connected between the aeration pipe 11 and the mounting block 9. A cylinder 17 is fixedly connected to the inner bottom wall of the column 3. Those skilled in the art can select a suitable model of cylinder 17 according to actual needs, such as SCD50x100-100-LB. A push block 18 is fixedly connected to the upper end of the cylinder 17. A push rod 19 is rotatably connected to the end of the aeration pipe 11 near the column 3. The push rod 19 moves through the column 3 and slides in contact with the push block 18. The longitudinal section of the push block 18 is an isosceles trapezoid. By moving the push block 18 up and down, the push rod 19 moves, changing the position of the aeration pipe 11. The hose 16 can adapt to the change of the angle of the aeration pipe 11. It is worth noting that the water level of the sewage inside the sewage tank 1 must be lower than the push rod 19 to prevent sewage from entering the inside of the column 3. The cylinder 17 is connected to the controller signal and is also powered by the photovoltaic panel 6.

[0034] When aeration is performed in the aeration pipe 11, the cylinder 17 can be activated to extend and retract, causing the push block 18 to move up and down. The push rod 19 can move along with the push block 18, thereby pushing the aeration pipe 11 and changing its longitudinal position. This allows the discharged oxygen to continuously aerate water at different depths. At the same time, as the aeration pipe 11 moves, the sewage at that location continuously diffuses to the outside, thereby improving the flow of sewage in the sewage tank 1 and effectively improving the aeration effect.

[0035] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
