Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to a river sewage treatment device. Background Art

[0002] Wastewater treatment is a crucial environmental project. It typically involves multiple stages, including physical, chemical, and biological treatment. Physical treatment primarily removes solid impurities from wastewater through screening and sedimentation. Chemical treatment utilizes chemical reactions to remove harmful substances, such as by adding reagents for flocculation and precipitation. Biological treatment utilizes the metabolic activity of microorganisms to break down organic pollutants in wastewater into harmless substances. After a series of treatments, pollutants are largely removed from wastewater, significantly improving water quality. Treated water can be used for irrigation, landscape water, and other uses, achieving water recycling. Furthermore, wastewater treatment reduces environmental pollution and protects the balance of ecosystems. The construction and operation of wastewater treatment facilities require substantial financial and technological investment. However, the long-term environmental and social benefits are enormous. They create a cleaner and healthier living environment for people and provide a strong foundation for sustainable development.

[0003] If sludge is not effectively collected during sewage treatment, it will re-enter the water body, causing secondary pollution. Silt often contains large amounts of harmful substances such as heavy metals, organic matter, and pathogens. These substances can spread with the water flow, contaminating surface water and groundwater, affecting the ecological environment and human health. For example, heavy metals can accumulate in aquatic organisms and be transmitted to humans through the food chain, causing damage to the human nervous system, immune system, and other organs. Secondly, sludge accumulation can affect the normal operation of sewage treatment facilities. Silt can clog equipment such as pipes, pumps, and filters, reducing sewage treatment efficiency and increasing operating costs. Summary of the Invention

By setting up a protective shell 51, the double-headed motor 52 can be protected to prevent water from splashing onto the double-headed motor 52 and damaging the double-headed motor 52. By setting up the double-headed motor 52, after the power is connected and the switch is turned on, the output end of the double-headed motor 52 can be rotated, and then the first rotating rod 53 drives the gear 54 to rotate.

[0033] A drainage mechanism 6 is fixedly connected to the side of the outer surface of the shell 1 away from the first connecting rod 55. The drainage mechanism 6 includes a second connecting rod 63. The second connecting rod 63 is fixedly connected to the outer surface of the shell 1. The end of the second connecting rod 63 is fixedly connected to a drainage pipe 62. By setting the drainage mechanism 6, the water flow that has been screened and silt removed can be discharged, and the river sewage can be guided so that the river sewage is fully in contact with the screening cylinder 36; the upper surface of the shell 1 is provided with a decontamination mechanism 7. By setting the decontamination mechanism 7, the silt that has passed through the screening cylinder 36 can be discharged, so that the water flow and the silt can be separated, and the silt can be collected.

[0034] The screening mechanism 3 also includes a positioning frame 31, which is slidably connected to the outer surface of the positioning rod 2. The lower surface of the positioning frame 31 is fixedly connected to the collection box 32, and the upper surface of the collection box 32 is fixedly connected to the positioning plate 33. By setting the positioning rod 2, the positioning frame 31 can be limited so that the positioning frame 31 can be connected to the lower surface of the shell 1, and after too much garbage is collected later, the collection box 32 can be separated from the shell 1.

[0035] A blocking mechanism 37 is fixedly connected to the bottom of the inner wall of the shell 1. The blocking mechanism 37 includes a discharge box 371. The discharge box 371 is squeezed and adapted to the positioning plate 33. The inner wall of the discharge box 371 is symmetrically fixed with blocking springs 372. By setting the blocking mechanism 37, the garbage in the inner cavity of the shell 1 can be blocked so that the garbage will not be discharged easily. Only when too much garbage accumulates, the garbage will be automatically discharged into the inner cavity of the collection box 32.

[0036] A first support rod 373 is fixedly connected to the inner wall of the discharge box 371, and the end of the first support rod 373 is fixedly connected to a limiting rod 374. The outer surface of the limiting rod 374 is slidably connected to a sliding ring 376. The outer surface of the limiting rod 374 is sleeved with a spring 375, and the top of the spring 375 is fixedly connected to the lower surface of the sliding ring 376. By setting the limiting rod 374, the sliding ring 376 can be limited so that the sliding ring 376 can move on the outer surface of the limiting rod 374. By setting the spring 375, the sliding ring 376 can rebound and return to its original position after moving on the outer surface of the limiting rod 374.

[0037] The top of the limit rod 374 is fixedly connected with a soft pad 377, and the outer surface of the sliding ring 376 is fixedly connected with a fixed frame 378. The upper surface of the fixed frame 378 is fixedly connected with a guide plate 379. By setting the blocking spring piece 372, the guide plate 379 can be blocked.

By setting the guide plate 379, it can contact the blocking spring piece 372 to prevent garbage from leaking. When in use, the garbage in the river sewage will pass through the holes of the screening cylinder 36 due to the large gravity and flow to the upper surface of the guide plate 379. After a lot of garbage accumulates, the sliding ring 376 will move downward on the outer surface of the limit rod 374, thereby increasing the gap between the guide plate 379 and the blocking spring piece 372, so that the garbage can fall into the inner cavity of the collection box 32. Finally, the collection box 32 can be taken out to collect the garbage.

[0038] The second embodiment, as Figure 7-Figure 8 As shown, the feeding mechanism 5 also includes a connecting box 57, which is fixedly connected to one end of the screening drum 36 close to the feeding pipe 56, and the connecting box 57 is sleeved on the end of the feeding pipe 56.

By providing the gear ring 511, when the gear 54 rotates, the gear ring 511 can be driven to rotate, thereby causing the connecting box 57 and the screening drum 36 to rotate.

[0039] A fixed block 58 is fixedly connected to the inner wall of the connection box 57. There are several fixed blocks 58, and the fixed blocks 58 are evenly distributed. A stirring plate 59 is fixedly connected to the side of the fixed block 58 away from the inner wall of the connection box 57. By arranging the fixed block 58 and the stirring plate 59, the stirring plate 59 can be rotated when the connection box 57 rotates, thereby stirring the water flow in the inner cavity of the shell 1, which can speed up the water flow processing.

[0040] The outer surface of the connecting box 57 is fixedly connected to the second support rod 512, and the end of the second support rod 512 is fixedly connected to the first rolling bearing 513. The inner ring of the first rolling bearing 513 is fixedly connected to the outer surface of the feed pipe 56. By setting the first rolling bearing 513, the feed pipe 56 and the connecting box 57 can be connected together while the rotation of the connecting box 57 will not affect the feed pipe 56. When in use, the operator connects the feed pipe 56 to the output end of the water pump, and then connects the double-headed motor 52 to the power supply and turns on the switch, so that the first rotating rod 53 drives the gear 54 to rotate, and then the gear ring 511 rotates, and drives the connecting box 57 and the stirring plate 59 to rotate, so that the sewage in the inner cavity of the screening cylinder 36 can be stirred, and the water flow through the holes of the screening cylinder 36 is accelerated.

The outer surface of the guide cone 65 is fixedly connected to a guide bar 66. There are several guide bars 66, and the guide bars 66 are evenly distributed. By providing the second rolling bearing 61, when the screening drum 36 rotates, the drain pipe 62 will not rotate and will be stably connected to the end of the screening drum 36. By providing the guide cone 65 and the guide bar 66, the water flow entering the inner cavity of the screening drum 36 can be guided so that the water flow directly flows to the inner wall of the screening drum 36.

[0042] The decontamination mechanism 7 includes a connecting pipe 71, which passes through the upper surface of the outer shell 1. The bottom end of the connecting pipe 71 is fixedly connected to a scraping frame 72, which is located directly above the screening drum 36. The top of the connecting pipe 71 passes through a transfer box 73, and the outer side of the transfer box 73 passes through a transfer box 74. The outer surface of the transfer box 74 passes through a sewage pipe 75. By providing the scraping frame 72, the sludge that passes through and adheres to the outer surface of the screening drum 36 can be scraped off, thereby keeping the outer surface of the screening drum 36 clean and tidy, and being able to collect the sludge.

By setting the second rotating rod 76, the second rotating rod 76 can drive the rotating sleeve 78 to rotate when the double-headed motor 52 is working. By setting the limiting post 79, the rotating sleeve 78 can be limited, so that the second rotating rod 76 can produce stable rotation. By setting the fan plate 77, when the second rotating rod 76 rotates, the fan plate 77 can rotate and generate suction in the inner cavity of the transfer box 73, thereby allowing the sludge to be sucked into the inner cavity of the transfer box 73.

[0044] Working principle: When in use, the operator connects the feed pipe 56 to the output end of the water pump, then connects the double-headed motor 52 to the power supply and turns on the switch, so that the first rotating rod 53 drives the gear 54 to rotate, and then the gear ring 511 rotates, and drives the connecting box 57 and the stirring plate 59 to rotate, and finally the sewage in the inner cavity of the screening cylinder 36 can be stirred, and the water flow is accelerated to pass through the holes of the screening cylinder 36; the garbage in the river sewage will pass through the holes of the screening cylinder 36 due to the greater gravity and flow to the upper surface of the guide plate 379. After a lot of garbage accumulates, the sliding ring 376 will When the outer surface of the limit rod 374 moves downward, the gap between the guide plate 379 and the blocking spring 372 becomes larger, so that the garbage can fall into the inner cavity of the collection box 32. Finally, the collection box 32 is taken out to collect the garbage. When the double-headed motor 52 rotates, the second rotating rod 76 drives the fan plate 77 to rotate, thereby generating suction in the inner cavity of the transfer box 73. When the screening drum 36 rotates, the scraping frame 72 scrapes off the silt attached to the outer surface of the screening drum 36 and under the action of the suction of the transfer box 73, the silt enters the inner cavity of the transfer box 73 and is discharged from the sewage pipe 75.
