Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to an adjustable centrifugal device for separating sewage suspended solids. Background Art

[0002] Sewage treatment refers to the process of treating domestic sewage, industrial wastewater, rainwater, etc. through various physical, chemical, and biological methods to remove or reduce pollutants in the water so that it meets the discharge standards or reuse requirements. Sewage treatment mainly includes stages such as pretreatment, primary treatment, secondary treatment, and advanced treatment. Pretreatment usually involves facilities such as screens and grit chambers for removing large solids and sand grains; primary treatment mainly removes suspended solids through sedimentation tanks; secondary treatment uses biological treatment methods such as the activated sludge method and the biofilm method to degrade organic matter; advanced treatment may include steps such as filtration, adsorption, and disinfection to further purify the water quality. The goal of sewage treatment is to protect the environment, conserve water resources, and achieve the sustainable utilization of water resources.

[0003] Currently, in the field of sewage treatment, traditional centrifugal devices for separating sewage suspended solids generally use a drum with mesh holes as the core separation component. By the high-speed rotation of the drum to generate centrifugal force, the separation of suspended solids in the sewage is achieved. However, this device has significant technical bottlenecks in practical applications: on the one hand, when the sewage contains suspended solids with larger sizes, these suspended solids are extremely likely to block the mesh holes on the drum, resulting in a decrease in the working efficiency of the device, and even frequent shutdowns for cleaning, increasing the maintenance cost and operation complexity; on the other hand, due to the lack of an effective collection mechanism for the suspended solids filtered out inside the drum, it is often difficult to centrally process and dispose of them, which not only brings inconvenience to the subsequent sewage treatment process but also may cause secondary pollution to the environment. Summary of the Invention

[0022] In the present invention, through the slag discharging mechanism provided, when it is necessary to discharge the suspended matter after it falls into the collection box, the fixed slag discharging plate is pushed towards the lower slag discharging port by the elongation of the electric push rod. At the same time, due to the elastic telescopic effect of the telescopic slag discharging plate, the outer end of the telescopic slag discharging plate closely adheres to the inner wall of the collection box. The stable sliding of the telescopic slag discharging plate and the fixed slag discharging plate is realized through the rollers. Thus, the suspended matter centrally collected inside the collection box is discharged through the lower slag discharging port and the slag discharging channel, achieving the rapid and smooth discharge of the suspended matter, effectively improving the efficiency and convenience of the treatment of the suspended matter, and at the same time ensuring the cleanliness of the equipment and the simplicity of maintenance.

Through the arranged slag conveying mechanism 3, the suspended matter in the sewage filtered by the first mesh hole 103 drives the first blade 302 to rotate through the rotation of the driving rod 301. The suspended matter is conveyed downward by the first blade 302 to the inner slag discharge port 306 on the surface of the inner plugging plate 304. The smaller particulate suspended matter in the sewage filtered by the second mesh hole 105 is conveyed downward by the rotation of the second blade 303 to the outer slag discharge port 307 on the surface of the outer plugging plate 305 and simultaneously falls into the collection box 309 for centralized collection, realizing the effective conveying and centralized collection of the suspended matter, avoiding the problem that the suspended matter is difficult to collect in traditional equipment, improving the convenience and efficiency of suspended matter treatment, and at the same time reducing the environmental pollution risk.

[0039] Example 4:

[0040] The slag discharging mechanism 4 is installed inside the collection box 309 and is used to centrally discharge the impurities centrally collected in the collection box 309. The slag discharging mechanism 4 includes a fixed slag discharging plate 402, a telescopic slag discharging plate 403 and an electric push rod 401. The fixed end of the electric push rod 401 is fixedly connected to the side surface of the fixed rod 109, and the telescopic end of the electric push rod 401 is fixedly connected to one side surface of the fixed slag discharging plate 402. The telescopic slag discharging plate 403 is movably connected to both side surfaces of the fixed slag discharging plate 402 through an elastic component. Roller 404 is rotatably connected to both sides of the telescopic slag discharging plate 403 away from the fixed slag discharging plate 402. Both the fixed slag discharging plate 402 and the movable slag discharging plate are closely attached to the inner lower surface of the collection box 309. Both the fixed slag discharging plate 402 and the movable slag discharging plate are movably connected inside the collection box 309. A lower slag discharging port 405 is penetrated and opened on the inner lower surface of the collection box 309. A slag discharging channel 406 is fixedly connected to the lower surface of the lower slag discharging port 405. Through the arranged slag discharging mechanism 4, when it is necessary to discharge the suspended matter after the suspended matter falls into the collection box 309, the fixed slag discharging plate 402 is pushed towards the lower slag discharging port 405 by the elongation of the electric push rod 401. At the same time, the outer end of the telescopic slag discharging plate 403 is closely attached to the inner wall of the collection box 309 through the elastic telescopic effect of the telescopic slag discharging plate 403. The stable sliding of the telescopic slag discharging plate 403 and the fixed slag discharging plate 402 is realized through the roller 404. Thus, the suspended matter centrally collected inside the collection box 309 is discharged through the lower slag discharging port 405 and the slag discharging channel 406 by the telescopic slag discharging plate 403 and the fixed slag discharging plate 402, realizing the rapid and smooth discharge of the suspended matter, effectively improving the efficiency and convenience of the suspended matter treatment, and at the same time ensuring the cleanliness of the equipment and the simplicity of the maintenance.

[0041] During use, after the device is started, the servo motor 201 starts to operate, driving the driving gear 202 to rotate through the transmission device. Sewage enters the inner cylinder 102 of the device main body 1 through the water inlet pipe 110. The water inlet pipe 110 is fixed on the fixed rod 109 by the pipe clamping mechanism 5 to ensure the smooth inflow of sewage. The inner cylinder 102 rotates forward under the drive of the driving gear 202 through the first tooth block 203. The first mesh holes 103 with a larger inner diameter formed on its surface initially filter the larger particulate suspended matter in the sewage under the action of centrifugal force, and these suspended matters are thrown into the space between the inner cylinder 102 and the outer cylinder 104. At the same time, the driving gear 202 drives the outer cylinder 104 to rotate in the reverse direction through the second tooth block 204. The second mesh holes 105 with a smaller inner diameter formed on the surface of the outer cylinder 104 perform secondary filtration on the sewage, and the smaller particulate suspended matters are thrown out to the space between the outer cylinder 104 and the outer waterproof cylinder 101, realizing double-layer filtration and effectively avoiding the problem of mesh blockage in single-layer filtration. As the suspended matters accumulate, the space between the inner cylinder 102 and the outer cylinder 104 is gradually filled. At this time, the induction device triggers the sewage discharge mechanism, the sewage discharge valve opens, and the separated suspended matters are discharged through the sewage discharge pipe. At the same time, the slag conveying mechanism 3 starts to work. The first blade 302 and the second blade 303 rotate under the drive of the drive rod 301, respectively conveying the suspended matters filtered by the inner cylinder 102 and the outer cylinder 104 downward to the slag discharge ports on the surfaces of the inner plugging plate 304 and the outer plugging plate 305, and finally falling into the lower collection box 309 for centralized collection. When it is necessary to discharge the suspended matters in the collection box 309, the slag discharge mechanism 4 is started. The electric push rod 401 extends to push the fixed slag discharge plate 402 towards the lower slag discharge port 405. The telescopic slag discharge plate 403 closely adheres to the inner wall of the collection box 309 under the action of the elastic component, and realizes stable sliding through the rollers 404, jointly discharging the suspended matters quickly through the lower slag discharge port 405 and the slag discharge channel 406. During the whole process, the device operates continuously, and the water supply system continuously supplies sewage to the inner cylinder 102 to ensure the treatment efficiency. In addition, the device is also provided with a cleaning mechanism to regularly clean the inner cylinder 102 and the outer cylinder 104, keep the device clean, simplify the maintenance process, and improve the overall performance and reliability of the device. Through this design, the device realizes efficient and reliable separation and treatment of sewage suspended matters, improving the effect and efficiency of sewage treatment.
