DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 3 The present invention provides an embodiment of a mobile wastewater sedimentation and filtration device, comprising a housing 1, the bottom of which is fixedly connected to a hydraulic support rod 22. After the housing 1 is moved to a location where wastewater treatment is required, the hydraulic support rod 22 is driven to extend to prop up the device, thereby ensuring the stability of the device during operation. The interior of the housing 1 is fixedly connected in sequence to partitions 1 3, 2 5, and 3 7, which respectively divide the interior of the housing 1 into a pretreatment zone, a mixing zone, a sedimentation zone, and a filtration zone. After the housing 1 is divided into these zones, the wastewater is discharged after being treated in these zones, thereby completing the wastewater treatment operation. The top of partition 2 5 is provided with an angled top, and a water baffle 6 is installed on the inner wall of the housing 1 at the side of partition 2 5. Partition 2 5 is located between the mixing zone and the sedimentation zone. The mixed wastewater flows from the top of partition 2 5 to the sedimentation zone, avoiding a large impact when flowing in. The addition of the water baffle 6 and the design of the top of partition 2 5 at an angle slow down the water flow.

[0033] Reference Figure 1-Figure 3 A water inlet pipe 2 is installed near the middle of the pretreatment area of the box 1. When treating wastewater, the wastewater needs to be pumped from the water inlet pipe 2 to the inside of the box 1. A filter screen 4 is fixedly connected to the middle of the partition 3. After the wastewater entering the pretreatment area is pretreated, it flows from the filter screen 4 to the mixing area. A stirring component 12 is installed in the pretreatment area, and a stirring component 2 13 is installed in the mixing area. The stirring component 12 and the stirring component 2 13 are used for stirring and mixing operations in the pretreatment area and the mixing area respectively. Their main structures are motors and stirring rods, which belong to the existing technology and will not be described in detail here. A dosing assembly is installed inside the housing 1. The dosing assembly includes a water tank 18, which is installed at the top of the housing 1. A connecting pipe 19 is installed on the outside of the water tank 18, and the other end of the connecting pipe 19 is installed at the top of the mixing zone. The water tank 18 is filled with flocculant. During the mixing operation, the flocculant is transported from the connecting pipe 19 to the inside of the mixing zone, and after cooperating with the stirring assembly 13, the flocculant and wastewater are mixed. A solenoid valve 20 is installed in the middle of the connecting pipe 19, and the solenoid valve 20 is used to adjust the flocculant addition rate. A feeding pipe 21 is installed on the outside of the water tank 18. The feeding pipe 21 is located outside the housing 1, and the flocculant is injected into the water tank 18 from the feeding pipe 21.

[0034] Reference Figure 2-Figure 3A filter assembly is installed inside the filter area. The filter assembly includes a filter sponge layer 9, a ceramic filter material layer 10, an activated carbon layer 11, and multiple filter plates 8. The filter plates 8 are fixedly connected to the filter area inside the box 1. The filter sponge layer 9, the ceramic filter material layer 10, and the activated carbon layer 11 are arranged in sequence between two adjacent filter plates 8. The top filter plate 8 performs preliminary filtration on the wastewater after sedimentation. The wastewater filtered by the filter plate 8 then permeates the filter sponge layer 9, the ceramic filter material layer 10, and the activated carbon layer 11 in sequence, thereby completing multi-stage filtration of the wastewater and ensuring the filtration effect. A sewage outlet 16 is also opened in the middle of the box 1. A gate valve 17 is installed on the outside of the box 1. The gate valve 17 is located at the outer edge of the sewage outlet 16. After long-term use, the top filter plate 8 will accumulate a lot of impurities, which can be discharged from the sewage outlet 16. After adding the gate valve 17, the sewage outlet 16 can be blocked.

[0035] Reference Figure 4 , multiple sewage pipes 15 for discharging sewage are installed on the outside of the box body 1. After treatment, the impurities located in the pretreatment area, mixing area and sedimentation area can be discharged from the sewage pipes 15. A drain pipe 14 is installed near the bottom of the filtration area of the box body 1, and the treated wastewater is discharged from the box body 1 through the drain pipe 14. A sewage collecting box 23 is fixedly connected to the outside of the box body 1, and the output ends of the multiple sewage pipes 15 are all located inside the sewage collecting box 23. A gate valve 24 is installed at the outlet end of the sewage collecting box 23. The waste residue discharged from the sewage pipe 15 can first flow into the sewage collecting box 23, and after being concentrated by the sewage collecting box 23, it can be discharged from the outlet section of the sewage collecting box 23 to increase the waste residue treatment speed. At the same time, the gate valve 24 is used to seal the outlet end of the sewage collecting box 23;

[0036] Reference Figure 3 and Figure 5 A connecting rod 25 is fixedly connected to the outside of the stirring assembly 12. The other end of the connecting rod 25 is fixedly connected to a spring rod 26. The other end of the spring rod 26 is fixedly connected to a scraper 27. A chute 28 is provided on the inside of the scraper 27. The scraper 27 is slidably connected to the outside of the connecting rod 25 through the chute 28. The partition 3 and the filter 4 are both arc-shaped, and the side of the filter 4 near the pretreatment area contacts the outer surface of the scraper 27. When the stirring assembly 12 is in operation, it drives the connecting rod 25 to rotate, and then the spring rod 26 pushes the scraper 27 outward, so that the scraper 27 contacts the filter 4. As the scraper 27 moves, it cleans the surface of the filter 4. The addition of the spring rod 26 and chute 28 allows the position of the scraper 27 to be adjusted according to the position of the filter 4, ensuring that the scraper 27 and the filter 4 can be fully mixed.

[0037] Working principle: When it is necessary to treat wastewater at a temporary construction site, the device is first moved to a specific position by a tractor, and the hydraulic support rod 22 is driven to support the device to ensure the stability of the device during operation. The wastewater is then connected to the water inlet pipe 2, thereby pumping the wastewater into the box 1. The wastewater first enters the pretreatment area, where it undergoes coagulation treatment. The treated wastewater flows through the filter 4 to the mixing area. At this time, larger impurities are blocked by the filter 4. The coagulation speed of the wastewater can be accelerated by the stirring component 12, and during the coagulation process, the stirring component 12 also drives the connecting rod 25 to rotate, and the spring rod 26 is used to push the scraper 27 outward, driving the scraper 27 to contact the inside of the filter 4, and scraping off the larger impurities accumulated on the inside of the filter 4, so as to improve the filtering effect of the filter 4 and extend the service life of the filter 4. The wastewater filtered by the filter 4 enters the mixing area. At this time, the flocculant inside the water tank 18 is discharged from the connecting pipe 19. It flows into the mixing zone, and the dosing speed is adjusted by the solenoid valve 20, and then the stirring component 2 13 is driven to work to fully mix the flocculant and the wastewater. After continuous addition of wastewater and flocculant, the wastewater water level eventually exceeds the partition 2 5. At this time, the wastewater will flow from the partition 2 5 to the sedimentation zone. After sedimentation, larger impurities accumulate at the bottom of the sedimentation zone, and then the wastewater level in the sedimentation zone continues to rise. After exceeding the height of the partition 3 7, it enters the filtration zone, and then the wastewater penetrates into the filter plate 8, the filter sponge layer 9, the ceramic filter material layer 10 and the activated carbon layer 11 in turn. After being filtered and processed by the filter plate 8, the filter sponge layer 9, the ceramic filter material layer 10 and the activated carbon layer 11, it flows into the bottom of the sedimentation zone, completing the treatment of the wastewater. The treated wastewater is discharged from the drain pipe 14.

[0038] After the treatment is completed, the sludge impurities inside the pretreatment area, mixing area, and sedimentation area can be discharged through the sewage pipe 15, and then after being collected by the sewage collecting box 23, they are discharged from the outlet end of the sewage collecting box 23. The waste residue at the top of the filtration area can be discharged from the sewage outlet 16. In this way, the device is emptied for transportation and the next treatment operation.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
