[0002] During routine operation and maintenance, municipal stormwater and sewage pipe networks accumulate large amounts of silt. This silt contains various debris, sand, gravel, and organic matter. Furthermore, the putrid odor of the organic matter affects the air environment. If not properly handled, it can cause serious water, soil, and air pollution, and even damage the ecological environment.
[0003] Existing sludge pretreatment devices are not convenient for separating impurities from sludge before pretreatment, which leads to a large number of impurities easily entering the hydraulic scrubber along with the sludge. This results in a large accumulation of impurities inside the hydraulic scrubber, affecting its operation and causing shutdowns. Utility Model Content

[0006] In a preferred embodiment, a flushing pipe is fixedly connected to the inner wall of the feed pipe, and a valve is rotatably installed on the inner wall of the flushing pipe.
[0007] By adopting the above technical solution, the flushing pipe can be connected to the water supply pipe, and then used to spray water on the inner wall of the feed pipe, thereby facilitating the cleaning of the inside of the feed pipe.
[0008] In one preferred embodiment, the inner wall of the filter screen is symmetrically provided with four insertion holes, and the cylinder is adapted to be inserted into the inner wall of the insertion holes.
[0009] By adopting the above technical solution, the cylinder can be used to position the filter screen, ensuring that it will not easily tilt when the sludge impacts the filter screen, thus ensuring the stability of the filter screen when it is installed inside the feed hopper.
[0010] In a preferred embodiment, the square piece is inserted into the inner wall of the square groove, and the side plate is disposed inside the platform support.
[0011] By adopting the above technical solution, the side plate can be used to support the filter screen, ensuring that the filter screen can be stably positioned in the same position inside the feed hopper.
[0012] In a preferred embodiment, the top of the sealing cover is provided with four slots evenly spaced, the slots and the handle are staggered, and the bottom of the handle is attached to the top of the sealing cover.
[0013] By adopting the above technical solution, the sealing cover can be positioned using a handle, ensuring that the sealing cover is stably set on the top of the platform support. After the handle and the slot are aligned, the sealing cover can be removed from the top of the feed hopper. The handle can also be used to lift the round rod away from the inner wall of the round hole.
[0014] In a preferred embodiment, the outer edge of the filter screen is fitted against the inner wall of the feed hopper, and the filter screen is made of stainless steel.
[0015] By adopting the above technical solution, the sludge discharged into the feed hopper can be filtered, effectively separating impurities and preventing impurities from accumulating inside the hydraulic scrubber, which would affect the subsequent sludge treatment efficiency.
[0016] In a preferred embodiment, the round rod is made of steel, and the outer diameter of the round rod is adapted to the inner diameter of the round hole.
[0017] By adopting the above technical solution, the stability of the round rod when it is installed on the inner wall of the round hole can be guaranteed, ensuring that it will not easily shake.
[0018] The beneficial effects of this application are:
[0019] This complete pretreatment system for sludge in drainage ditches can filter and separate impurities from the sludge by setting up a filter screen. This avoids the problem that a large amount of impurities can easily enter the hydraulic scrubber along with the sludge, which would lead to a large accumulation of impurities inside the hydraulic scrubber and affect its operation. At the same time, the handle can be pulled to move the round rod out of the round hole, so that the filter screen can be moved to the outside for cleaning and maintenance, ensuring its unobstructed flow. The handle and the slot are staggered to be used for positioning the sealing cover.
[0020] This complete pretreatment system for sludge in drainage ditches connects a flushing pipe to a water supply pipe, which is then used to spray water onto the inner wall of the feed pipe. This allows for convenient cleaning of the inside of the feed pipe, avoiding any unpleasant odors inside the feed pipe after cleaning the hydraulic scrubber and the feed hopper.

Detailed Implementation
[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0027] Reference Figure 1-4 A complete pretreatment system for sludge from drainage ditches includes a platform support 1. A hydraulic scrubber 2 is fixedly installed on the top of the platform support 1. A grading roller 3 is connected to the outside of the hydraulic scrubber 2. A discharge pipe 4 is fixedly connected to the side of the grading roller 3 away from the hydraulic scrubber 2. A feed pipe 5 is fixedly connected to the side of the hydraulic scrubber 2 away from the grading roller 3. A feed hopper 6 is fixedly connected to the top of the feed pipe 5. A sealing cover 9 is installed on the top of the feed hopper 6. A round hole 11 and a square groove 12 are opened on the top of the feed hopper 6. A round rod 13 is inserted into the inner wall of the round hole 11. A side plate 15 is fixedly connected to the outside of the round rod 13 through a square plate 14. A cylinder 16 is fixedly installed on the top of the side plate 15. A filter screen 17 is fixedly installed on the inner side of the feed hopper 6. A handle 19 is threadedly connected to the top of the round hole 11.
[0028] See Figure 2A flushing pipe 7 is fixedly connected to the inner wall of the feed pipe 5. A valve 8 is rotatably installed on the inner wall of the flushing pipe 7, so that the flushing pipe 7 can be connected to the water supply pipe for spraying water on the inner wall of the feed pipe 5, thereby facilitating the cleaning of the inside of the feed pipe 5.
[0029] See Figure 4 The inner wall of the filter screen 17 is symmetrically provided with four insertion holes 18. The cylinder 16 is adapted to be inserted into the inner wall of the insertion hole 18, so that the cylinder 16 can be used to position the filter screen 17, ensuring that the filter screen 17 will not easily tilt when the sludge impacts the filter screen 17, and ensuring the stability of the filter screen 17 when it is set inside the feed hopper 6.
[0030] See Figure 4 The square plate 14 is inserted into the inner wall of the square groove 12, and the side plate 15 is set inside the platform support 1, so that the side plate 15 can be used to support the filter screen 17, ensuring that the filter screen 17 can be stably placed in the same position inside the feed hopper 6.
[0031] See Figure 2 and Figure 4 The top of the sealing cover 9 is evenly provided with four slots 10. The slots 10 and the handles 19 are staggered. The bottom of the handles 19 fits against the top of the sealing cover 9, so that the sealing cover 9 can be positioned by the handles 19, ensuring that the sealing cover 9 is stably set on the top of the platform support 1. After the handles 19 and the slots 10 are aligned, the sealing cover 9 can be removed from the top of the feed hopper 6. The handles 19 can also be used to lift the round rod 13 away from the inner wall of the round hole 11.
[0032] See Figure 2 - Figure 4 The outer edge of the filter screen 17 fits against the inner wall of the feed hopper 6. The filter screen 17 is made of stainless steel, which allows the sludge discharged into the feed hopper 6 to be filtered, effectively separating impurities and preventing impurities from accumulating inside the hydraulic scrubber 2, thus affecting the subsequent sludge treatment efficiency.
[0033] See Figure 4 The round rod 13 is made of steel. The outer diameter of the round rod 13 is matched with the inner diameter of the round hole 11, which ensures the stability of the round rod 13 when it is installed on the inner wall of the round hole 11 and prevents it from easily shaking.
[0034] Working principle: When using this device, the handle 19 and the slot 10 are first offset to stably position the slot 10 on the top of the feed hopper 6, sealing the opening at the top of the feed hopper 6. At the same time, the handle 19 can be rotated to align with the slot 10 to release the positioning of the sealing cover 9, thereby removing the slot 10 from the top of the feed hopper 6. Then, sludge can be added into the feed hopper 6 and filtered by the filter screen 17. The filtered sludge enters the hydraulic scrubbing machine 2 through the feed pipe 5 for rinsing. Simultaneously, the handle 19 can be pulled to move the round rod 13 out of the round hole 11, thereby moving the filter screen 17 to the outside for cleaning and maintenance to ensure its unobstructed flow.
