Description

Technical Field

[0001] This invention relates to the field of environmental engineering, and more specifically, to a wastewater treatment device for environmental engineering. Background Technology

[0002] Environmental engineering is a branch of environmental science that primarily studies how to protect and rationally utilize natural resources, and uses scientific methods to solve increasingly serious environmental problems, improve environmental quality, and promote environmental protection and social development. It is the science and technology that studies and engages in the prevention and control of environmental pollution and the improvement of environmental quality. Environmental engineering is related to ecology in biology, environmental hygiene and environmental medicine in medicine, as well as environmental physics and environmental chemistry. Because environmental engineering is still in its early stages and the field is still developing, its core is the treatment of environmental pollution sources. This mainly includes water pollution control, domestic water supply, air pollution control, solid waste disposal, noise pollution control, as well as radioactive pollution control, thermal pollution control, and electromagnetic radiation control. Water pollution control requires wastewater treatment equipment, which treats domestic sewage and industrial wastewater, turning it into a usable water source, preventing sewage and pollutants from directly flowing into water bodies, and playing a significant role in improving the ecological environment.

[0003] Existing wastewater treatment devices for environmental engineering mainly consist of equalization tanks, anoxic tanks, biological reaction tanks, sedimentation tanks, and disinfection tanks. Inclined tube sedimentation tanks are a type of sedimentation tank, which are composed of a tank body, inlet mechanism, outlet mechanism, sludge removal mechanism, and inclined tube packing. However, the inclined tube packing is directly laid flat in the tank body. During use, wastewater flows upward from the bottom of the inclined tube packing to achieve the purification effect. The wastewater can only pass through the inclined tube packing once, resulting in poor purification effect. Moreover, during long-term use, sludge will adhere to the inner wall of the inclined tube packing, requiring frequent shutdowns for cleaning, which is time-consuming, labor-intensive, and delays wastewater treatment work. Therefore, there is an urgent need to design a wastewater treatment device for environmental engineering. Summary of the Invention

Technical problems to be solved Existing wastewater treatment devices for environmental engineering mainly consist of equalization tanks, anoxic tanks, biological reaction tanks, sedimentation tanks, and disinfection tanks. Inclined tube sedimentation tanks, a type of sedimentation tank, are composed of a tank body, inlet mechanism, outlet mechanism, sludge removal mechanism, and inclined tube packing. However, the inclined tube packing is directly laid flat inside the tank body. During use, wastewater flows upward from the bottom of the inclined tube packing to achieve purification. The wastewater only passes through the inclined tube packing once, resulting in poor purification efficiency. Furthermore, during prolonged use, sludge adheres to the inner wall of the inclined tube packing, requiring frequent shutdowns for cleaning, which is time-consuming, labor-intensive, and disrupts wastewater treatment operations.

[0028] Working principle: First, wastewater enters the primary sedimentation tank 103 through the inlet bend 114. Then, the wastewater inside the primary sedimentation tank 103 flows upward and passes through the first inclined tube packing 24. Next, the wastewater overflows from the top of the first inclined tube packing 24 and flows to the left on the top surface of the first inclined mounting base 21. Afterward, the wastewater enters the first water conveying groove 32, then passes through the first water conveying short pipe 33 and enters the first independent water chamber 35. Next, the wastewater passes through the first water conveying through hole 36 and enters the first optimization tank 104. Then, the wastewater inside the first optimization tank 104 flows upward and passes through the second inclined tube packing 24 above it. Then, the wastewater overflows from the top of the second inclined tube packing 24 and flows to the left on the top surface of the second inclined mounting base 21. Next, the wastewater enters the second water conveying groove 32. The wastewater flows through the second water supply short pipe 33 into the second independent water chamber 35, then through the second water supply through hole 36 into the second optimization tank 104. Inside the second optimization tank 104, the wastewater flows upward and through the third inclined tube packing 24 above it. The wastewater then overflows from the top of the third inclined tube packing 24 and flows to the left on the top surface of the third inclined mounting base 21. Next, the wastewater enters the third water supply groove 32, then through the third water supply short pipe 33 into the third independent water chamber 35. The wastewater then flows through the third water supply through hole 36 into the third optimization tank 104. Inside the third optimization tank 104, the wastewater flows upward and through the fourth inclined tube packing 24 above it. The wastewater then overflows from the top of the fourth inclined tube packing 24 and flows to the left on the top surface of the fourth inclined mounting base 21. The wastewater flows to the left on the top surface of the fifth inclined mounting base 21, then enters the fourth water conveying groove 32, then passes through the fourth water conveying short pipe 33 into the fourth independent water chamber 35, and then passes through the fourth water conveying through hole 36 into the fourth optimization tank 104. The wastewater inside the fourth optimization tank 104 then flows upward and passes through the fifth inclined tube packing 24 above it. After being treated by the five inclined tube packings 24, the wastewater becomes purified water. The purified water then overflows from the top of the fifth inclined tube packing 24 and flows to the left on the top surface of the fifth inclined mounting base 21. The purified water then enters the fifth water conveying groove 32, then passes through the fifth water conveying short pipe 33 into the fifth independent water chamber 35, and then passes through the fifth water conveying through hole 36 into the clean water tank 105. The purified water then flows from... The purified water discharge pipe 109 discharges to the next treatment stage. After the wastewater treatment device for this environmental engineering project has been running for a period of time, the intelligent distribution cabinet 112 starts the cleaning program. At this time, the alignment sensor 43 aligns with the first positioning sensor 42, causing the intelligent distribution cabinet 112 to control the extension of the electric telescopic rod 62. Then, the electric telescopic rod 62 moves diagonally downward with the plugging coordination block 63. Next, the plugging coordination block 63 moves diagonally downward with the plugging rod 65. Then, the plugging rod 65, along with the flushing structure 8, extends into the right half of the pipe hole of the first inclined tube packing 24. The left half of the pipe hole is used to purify wastewater. At this time, the extension amount of the electric telescopic rod 62 is the same as the first preset value inside the intelligent distribution cabinet 112. Then, the intelligent distribution cabinet 112 controls the booster pump 71 to start.Next, driven by the booster pump 71, the purified water enters the plugging coordination block 63 through the booster pipe 72, pressure water pipe 73, pressure hose 77, and hydraulic water pipe 66. Then, the purified water enters the feed cone shell 83 through the plugging rod 65 and the spray hole 85. Finally, the purified water is sprayed out from the spray ring 84 to flush the inner wall of the pipe hole on the inclined tube packing 24. Next, the intelligent distribution cabinet 112 controls the electric telescopic rod 62 to continue extending. Then, the flushing structure 8 moves obliquely downwards in the pipe hole on the inclined tube packing 24, pushing out the accumulated mud in the pipe hole, achieving the purpose of plugging. Then, the electric telescopic rod 62 extends to its longest state. At this time, the flushing structure 8 leaks out from the bottom end of the pipe hole on the inclined tube packing 24, and the extension of the electric telescopic rod 62 reaches the inner wall of the intelligent distribution cabinet 112. The second preset value of the first inclined tube packing 24 is reached, completing the plugging operation on the right half of the tube hole. Then, the intelligent distribution cabinet 112 controls the electric telescopic rod 62 to shorten, and simultaneously controls the booster pump 71 to stop running, causing the flushing structure 8 to stop spraying water. After that, the electric telescopic rod 62, through the plugging coordination block 63 and the plugging rod 65, pulls the flushing structure 8 out of the tube hole on the inclined tube packing 24. Then, the plugging coordination block 63 contacts the progressive slider 52. At this time, the electric telescopic rod 62 is shortened to its shortest state, and the extension of the electric telescopic rod 62 reaches the third preset value inside the intelligent distribution cabinet 112. Then, the intelligent distribution cabinet 112 controls the progressive motor 55 to run. Then, the progressive motor 55 drives the progressive screw 53 to rotate, and then the progressive slider 52 moves through its contact with the progressive screw 53. The threaded engagement between the progressive slider 52 and the plugging structure 6 moves downwards and to the left a certain distance. When the progressive slider 52 finishes moving, the flushing structure 8 aligns with the left half of the tube hole on the first inclined tube packing 24. This process is repeated to complete the plugging operation on the left half of the tube hole on the first inclined tube packing 24. This completes the plugging operation on all tube holes on the first inclined tube packing 24. Afterwards, the intelligent distribution cabinet 112 controls the electric telescopic rod 62 to shorten to its shortest state. Then, the intelligent distribution cabinet 112 controls the progressive motor 55 to run. The progressive motor 55 then rotates the progressive screw 53. Subsequently, the progressive slider 52, under the action of the threaded engagement between itself and the progressive screw 53, moves the plugging structure 6 downwards and to the left. Simultaneously, the progressive slider 52 moves the alignment sensor 43 downwards and to the left. Then, the alignment sensor 43 is aligned with the second positioning sensor 42. Next, the intelligent distribution cabinet 112 controls the progressive motor 55 to stop. At this point, the flushing structure 8 is aligned with the right half of the pipe hole on the second inclined tube packing 24. Then, the intelligent distribution cabinet 112 controls the electric telescopic rod 62 to extend, beginning the unblocking operation on the second inclined tube packing 24. This process is repeated until the unblocking operation on the fifth inclined tube packing 24 is completed. At this point, the alignment sensor 43 is aligned with the fifth positioning sensor 42, and the electric telescopic rod 62 is in its shortest state. Next, the intelligent distribution cabinet 112 controls the progressive motor 55 to run in reverse until the alignment sensor 43 is aligned with the first positioning sensor 42. Then, the intelligent distribution cabinet 112 controls the progressive motor 55 to stop, completing the reset of the unblocking structure 6.That's all.
