DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

As shown in Figure 1, a sewage wastewater collection device with automatic filter membrane replacement includes a water pipe 1, a filtering mechanism 2, a water purification mechanism 3, a stop valve 4, a collection mechanism 5 and a control panel 6. The filtering mechanism 2, the water purification mechanism 3 and the stop valve 4 are installed on the water pipe 1, and the collection mechanism 5 is installed at the end of the water pipe 1. The filtering mechanism 2 performs secondary filtration on the sewage wastewater, the water purification mechanism 3 uses clean water to clean the water pipe 1, and discharges the cleaned dirt to the outside of the device through the water pipe 1. The stop valve 4 prevents the clean water from flowing into the collection mechanism 5. The collection mechanism 5 collects the filtered sewage wastewater, and the control panel 6 is electrically connected to the filtering mechanism 2, the water purification mechanism 3, the stop valve 4 and the collection mechanism 5, and is used to control the start and stop of the filtering mechanism 2, the water purification mechanism 3, the stop valve 4 and the collection mechanism 5.

Specifically, the filter mechanism 2 includes a primary filter assembly 21 and a secondary filter assembly 22, which are installed on the water pipe 1. The primary filter assembly 21 filters large particles, and the secondary filter assembly 22 filters fine particles. The primary filter assembly 21 includes a filter screen 212, a first ejector pin 213, and an automatic filter screen changer 211. The filter screen 212 is arranged on the water pipe 1. The automatic filter screen changer 211 changes the filter screen 212 located on the water pipe 1. The automatic filter screen changer 211 is provided with a hollow filter screen frame, which is arranged on the water pipe 1. The first ejector pin 213 positions the filter screen 212 and the hollow filter screen frame, which can prevent the hollow filter screen frame from having a gap with the water pipe 1, so that leakage occurs during sampling or cleaning. When the filter screen of the first-level filter assembly 21 needs to be replaced, the automatic filter screen changer 211 drives the hollow filter screen frame to extend into the water pipe 1, and the first ejector pin 213 lifts the hollow filter screen frame to prevent waste water or clean water from leaking. The automatic filter screen changer 211 replaces the filter screen 212 located on the water pipe 1, and retracts the hollow filter screen frame after the replacement is completed. The secondary filter assembly 22 includes a filter membrane 222, a second ejector pin 223, and an automatic filter membrane changer 221. The filter membrane 222 is arranged on the water pipe 1. The automatic filter membrane changer 221 replaces the filter membrane 222 located on the water pipe 1. The automatic filter membrane changer 221 is provided with a hollow filter membrane frame, and the hollow filter membrane frame is arranged on the water pipe 1. The second ejector pin 223 positions the filter membrane 222 and the hollow filter membrane frame, which can prevent the gap between the hollow filter membrane frame and the water pipe 1, so that leakage occurs during sampling or cleaning. When the filter membrane of the secondary filter assembly 22 needs to be replaced, the automatic filter membrane changer 221 drives the hollow filter membrane frame to extend into the water pipe 1, and the second ejector pin 223 lifts the hollow filter membrane frame to prevent leakage of waste water or clean water. The automatic filter membrane changer 221 replaces the filter membrane 222 located on the water pipe 1, and retracts the hollow filter membrane frame after the replacement is completed.

Specifically, the water purification mechanism 3 includes a flushing pump 32, a flushing pipe 33 and a clean water tank 31. The clean water tank 31 is connected to the flushing pump 32 through the flushing pipe 33, and the flushing pump 32 is connected to the water pipe 1 through the flushing pipe 33. The flushing pump 32 pumps the clean water in the clean water tank 31 into the water pipe 1 for cleaning.

Specifically, the collection mechanism 5 includes a collection water pipe 55, a water collector 51, a first peristaltic pump 52, a quantitative ring 53 and a second peristaltic pump 54. The water collector 51 is installed at the end of the water pipe 1 and is connected to the first peristaltic pump 52, the quantitative ring 53 and the second peristaltic pump 54 in sequence through the collection water pipe 55. The water collector 51 extracts wastewater through the water pipe 1, and then filters it through the primary filter component 21 and the secondary filter component 22 to obtain usable wastewater. The first peristaltic pump 52 pumps the wastewater into the quantitative ring 53, and then extracts the quantitative ring 53 through the second peristaltic pump 54, thereby completing the collection of the wastewater.

When the above-mentioned sewer wastewater collection device with automatic replacement of filter membrane needs to replace the filter membrane filter screen, the control panel 6 controls the stop valve 4 to close, the automatic filter screen changer 211 drives the hollow filter screen frame to extend into the water pipe 1, and the first ejector pin 213 lifts the hollow filter screen frame to prevent leakage of wastewater or clean water, the automatic filter membrane changer 221 drives the hollow filter membrane frame to extend into the water pipe 1, and the second ejector pin 223 lifts the hollow filter membrane frame to prevent leakage of wastewater or clean water, the control panel 6 controls the flushing pump 32 to start, and pumps the clean water in the clean water tank 31 into the water pipe 1 for cleaning, the automatic filter screen changer 211 replaces the filter screen 212 located on the water pipe 1, and the automatic filter membrane changer 221 replaces the filter membrane 222 located on the water pipe 1. After the replacement is completed, the flushing pump 32 stops.

When sampling is required, the water collector 51 draws wastewater through the water pipe 1, and then filters it through the primary filter component 21 and the secondary filter component 22 to obtain usable wastewater. The first peristaltic pump 52 pumps the wastewater into the quantitative ring 53, and then the quantitative ring 53 is extracted through the second peristaltic pump 54, thereby completing the collection of the wastewater.
