[0002] Wetlands, as ecological wastewater treatment systems, are widely used in the treatment of urban sewage, industrial wastewater, and rural non-point source pollution due to their low energy consumption and sustainability. During the operation of constructed wetlands, suspended solids, organic matter, and microbial metabolic products in the wastewater gradually accumulate to form sludge. If this sludge is not cleaned and transported in a timely manner, it will lead to blockage of the wetland filler, reduced hydraulic conductivity, and even secondary pollution, seriously affecting treatment efficiency and ecological functions.

[0003] Wetland sludge has a complex composition, often containing impurities such as fibers and gravel. Existing conveying equipment is prone to clogging, which requires manual intervention and affects work efficiency. Furthermore, it is inconvenient to add chemicals during the conveying of wetland sludge.

[0004] To address these issues, a sludge conveying device for wetlands is proposed. Utility Model Content

[0022] Reference Figure 1-2 This utility model provides a sludge conveying device for wetlands, comprising:

[0023] The filter assembly includes a filter box 1 with an open top. A movable plate 2 is slidably mounted on the top of the filter box 1. A hose 3 is fixedly connected to the movable plate 2. The hose 3 passes through the movable plate 2 and is connected to a sludge pump 4. Two filter screens 14 are detachably connected inside the filter box 1. Two first discharge ports 5 are opened on the bottom surface of the filter box 1. Two dosing mechanisms are connected to the filter box 1.

[0024] The conveying assembly includes a housing 6, on which a first motor 7 is mounted. A rotating shaft 8 is rotatably connected inside the housing 6. The output shaft of the first motor 7 is fixedly connected to the rotating shaft 8. A spiral blade 9 is fixedly connected to the rotating shaft 8. The housing 6 has a first inlet and a second outlet. Both first outlets 5 are connected to the first inlet. The housing 6 and the filter box 1 are both fixedly connected to a base plate 10. Several rollers 11 are installed on the base plate 10.

[0025] In this device, the filter box 1 is used to filter sludge. The sludge pump 4 pumps the sludge into the filter box 1. The filter screen 14 filters the sludge. The discharge end of the hose 3 is fixed on the moving plate 2. When there is a lot of debris on one filter screen 14, the moving plate 2 is dragged to move the moving plate 2 above another filter screen 14, which can clean the filter screen 14 with more debris. The filtered sludge is discharged through the first discharge port 5. The dosing mechanism facilitates the addition of chemicals to the sludge to suppress odor or disinfect pathogens. The filtered sludge enters the outer shell 6. The first motor 7 drives the rotating shaft 8 and the spiral blade 9 to rotate, which can transport the sludge over long distances. The base plate 10 and the rollers 11 facilitate the movement of this device.

[0026] In a further optimized design, a partition 12 is fixedly connected inside the filter box 1, which divides the filter box 1 into two chambers 13. Two filter screens 14 are respectively installed in the two chambers 13, and two first discharge ports 5 are respectively located in the two chambers 13.

[0027] The partition 12 divides the filter box 1 into two chambers 13, which facilitates the placement of the filter screen 14 and also makes it easy to clean the debris on the filter screen.

[0028] The scheme is further optimized. Several fixing blocks 15 are fixedly connected to the inner side wall of the filter box 1 and the partition 12. The fixing blocks 15 are provided with mounting holes. The filter screen 14 is fixedly connected with a plug rod 16, which is inserted into the mounting hole. The filter screen 14 is fixedly connected with a first handle 17.

[0029] The fixing block 15 is used to install the filter screen 14, and the first handle 17 makes it easy to remove the filter screen 14 for maintenance and replacement.

[0030] The scheme is further optimized by fixing two sliding grooves 18 on the inner side wall of the filter box 1. The two sliding grooves 18 are arranged opposite each other. The movable plate 2 is slidably arranged in the sliding grooves 18. A second handle 26 is fixedly connected to the movable plate 2.

[0031] The movable plate 2 slides within the two slide grooves 18. When it is necessary to clean or replace the filter screen 14, the movable plate 2 can be dragged by the first handle 17 to move the movable plate 2 to free up the filter screen 14 that needs to be cleaned or replaced, and then the next operation can be carried out on the filter screen 14.

[0032] The scheme is further optimized so that a first connecting pipe 19 is connected to the first discharge port 5, and a second connecting pipe 20 is connected to the first inlet port. The first connecting pipe 19 and the second connecting pipe 20 are connected.

[0034] The scheme is further optimized. The dosing mechanism includes a medicine tank 21, which is connected to the filter box 1 through a third connecting pipe 22. A valve 23 is installed on the third connecting pipe 22.

[0035] The top of the medicine tank 21 is open, so the medicine can be poured into the medicine tank 21 and then the valve 23 can be opened to allow the medicine to enter the filter box 1. The size of the valve 23 can be adjusted.

[0036] In a further optimized design, the filter box 1 is fixedly connected to the base plate 10 by several first support columns 24, the outer shell 6 is fixedly connected to the base plate 10 by several second support columns 25, a connecting ring 27 is fixedly connected to the base plate 10, and the first motor 7 is fixedly connected to the outer shell 6 by a first connecting plate 26.

[0037] The connecting ring 27 facilitates dragging this device.

[0038] The device is used by pumping sludge with a sludge pump 4. The sludge enters the filter box 1 through a hose 3. When there is a lot of debris on a filter screen 14, the moving plate 2 can be dragged by the first handle 17 to move the moving plate 2 to free up the filter screen 14 that needs to be cleaned or replaced. Then, the next step is to pour the medicine into the medicine tank 21 and open the valve 23 to let the medicine enter the filter box 1. The filtered sludge enters the first connecting pipe 19 through the first discharge port 5, and then enters the second connecting pipe 20 from the first connecting pipe 19, and finally enters the outer shell 6. The first motor 7 drives the rotating shaft 8 and the spiral blades 9 to rotate, which can transport the sludge over long distances.
