Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an automatic slag discharge type wastewater treatment device with wastewater sedimentation and separation function. Background Technology

[0002] This paper discusses the advancements in sedimentation technology, focusing on sedimentation as the primary method for removing suspended solids from water. It primarily introduces the characteristics and advantages of horizontal flow sedimentation tanks, honeycomb inclined tube sedimentation tanks, high-density sedimentation tanks, and interception sedimentation tanks, aiming to improve the settling efficiency of sedimentation tanks. Currently, most domestic and international water treatment processes employ sedimentation (clarification) filtration and disinfection, with sedimentation playing a particularly crucial role in removing suspended solids from raw water. Sedimentation tanks, as one of the main facilities for removing suspended solids from water, are widely used in the water industry. Looking at the development of sedimentation structures, it can be seen that before the 1960s, horizontal flow, vertical flow, and radial flow sedimentation tanks were mainly used. From the 1960s onwards, various clarification tanks became popular, and after the 1970s, inclined tube, inclined plate, and composite sedimentation tanks became the main types. Improvements in sedimentation structure design have increased the efficiency of sedimentation separation. The design and development of sedimentation tanks revolve around increasing the sedimentation area and altering the water flow pattern. The design of sedimentation tanks always aims to improve the settling efficiency. Summary of the Invention

[0070] Preferably, a floating microfiltration mechanism 40 is provided connected to the sedimentation container 11.

Multiple microfiltration flow tubes 421 are fixedly connected to the outside of the microfiltration rotating shell 42.

[0071] A filter-blocking flow shell 422 with multiple openings facing the microfiltration rotating shell 42 is fixedly provided on the outside of the microfiltration flow tube 421, and a floating microfiltration filter element 423 is fixedly provided inside the filter-blocking flow shell 422.

[0072] The microfiltration flow tube 421 has a through hole that communicates with the filter flow shell 422;

[0073] The lower end of the solid-liquid separation main pipe 12 is connected to the interior of the floating microfiltration container tank 41 via a pipe.

[0074] Multiple centrifugal drive blades 424 are fixedly mounted on the top of the microfiltration rotating shell 42.

[0075] In practical application, the wastewater after flocculation treatment is input into the sedimentation tank 11. The guide rotation support ring 243 is driven by a motor to rotate. The guide rotation support ring 243 drives multiple guide drive blades 244 to rotate together. Under the drive of the multiple guide drive blades 244, the wastewater is transported into the sedimentation separation space 200 through the guide promotion through hole 245.

[0076] The sedimentation partition support plate 201 has multiple vertically penetrating outward discharge holes near the inner wall of the sedimentation container tank 11.

[0077] Wastewater entering the sedimentation partition space 200 flows toward the edge of the sedimentation partition support plate 201 and then flows back into the sedimentation container tank 11 through the outflow hole. During the process of the wastewater flowing toward the edge of the sedimentation partition support plate 201, it flows through each sedimentation filter ring shell 21 and uses the sedimentation filter plate 22 to filter and intercept solid particles in the wastewater.

[0078] The filter plate cleaning rotating ring 252 is driven by a motor to rotate periodically around the filter plate cleaning support ring 251. The filter plate cleaning rotating ring 252 drives multiple scraper connecting columns 253 to move together with the filter plate cleaning scrapers 254. The filter plate cleaning scrapers 254 push the particulate matter attached to the surface of the sedimentation filter plate 22 to the nearest sedimentation separation conveying pipe 23. The particulate matter enters the sedimentation separation conveying pipe 23 through the sedimentation input slot 231. The particulate matter is conveyed by the spiral conveying rod 232 and discharged through the pipe.

[0079] After being continuously filtered by the sedimentation filter plate 22, the wastewater is then treated by the separation and discharge mechanism 30 before being discharged. The wastewater in the sedimentation tank 11 passes through the separation and discharge filter plate 311 and enters the separation and discharge ring 31. The second valve 313 is opened, and the wastewater in the separation and discharge ring 31 enters the solid-liquid separation main pipe 12 through the separation and discharge conveying pipe 312. The wastewater is then discharged through the solid-liquid separation main pipe 12.

[0080] The surface of the separation external discharge filter plate 311 is cleaned by the external discharge cleaning mechanism 32. The circumferential rotating support ring 332 is driven by a servo motor to rotate around the circumferential cleaning support ring rail 331. The circumferential rotating support ring 332 drives the radial support rod 333 together with the external discharge cleaning container 322 to move along the outer side of the separation external discharge container ring 311. The external discharge sweeping rod 329 rotates and uses the sweeping brush to clean off the dirt on the surface of the separation external discharge filter plate 311. The dirt that has been cleaned off enters the external discharge cleaning container 322 through the external discharge cleaning slot 323. Under the conveying action of the slag collection and conveying spiral blade 325, the dirt that has been cleaned off is discharged through the slag collection external discharge pipe 326.

[0081] The debris that falls off the cleaning system is mixed with sewage and enters the external discharge cleaning container 322. The outer wall of the water circulation pipe 324 has a porous structure and acts as a filter, blocking the debris that falls off the cleaning system on the outside of the water circulation pipe 324. The sewage then enters the water circulation pipe 324 and is discharged back into the sedimentation container 11 through the pipe, thus forming a circulating water flow in the external discharge cleaning container 322.

[0082] Wastewater discharged through the solid-liquid separation manifold 12 is transported to the floating microfiltration container tank 41. The microfiltration rotating shell 42 is driven to rotate by a motor. The microfiltration rotating shell 42 drives multiple microfiltration flow tubes 421 to rotate together. Under the action of centrifugal stirring, the wastewater in the floating microfiltration container tank 41 continuously flows back and forth from the center to the edge. The circulating wastewater enters the filter flow shell 422 and is filtered through the floating microfiltration filter element 423 to remove residual solid particle impurities in the wastewater. The wastewater in the filter flow shell 422 passes through the passage on the side wall of the microfiltration flow tube 421 and enters the inside of the microfiltration flow tube 421. Then it is discharged from the end of the microfiltration flow tube 421 away from the microfiltration rotating shell 42, completing the water circulation.

[0083] After filtering out the solid particulate impurities remaining in the wastewater, the wastewater can be discharged from the floating microfiltration container 41.

[0084] The sedimentation filter plate 22 and the separation discharge filter plate 311 are existing wastewater treatment filter plates, and the floating microfiltration filter element 423 is an existing particulate filter element.
