Description

Technical Field

[0001] This utility model relates to the field of sludge cleaning technology, specifically to a sludge cleaning device for sedimentation tanks. Background Technology

[0002] Photovoltaic power generation projects are an important form of clean energy production utilizing solar energy, typically constructed in areas with abundant resources and relatively open land. Because photovoltaic panels require large-scale deployment, project sites are often located in mountainous, hilly, or barren slope areas. These areas have significant topographical variations and fragile ecosystems, and the construction and operation processes can have a substantial impact on local soil and water conservation. Therefore, in the construction and operation of photovoltaic power generation projects, in addition to ensuring the stability of power production, ecological protection and environmental governance must also be considered. To reduce soil erosion, drainage ditches and sedimentation basins are usually constructed as part of the project to intercept and settle silt carried by rainwater. The sedimentation basins in photovoltaic power generation projects are generally small in capacity and scattered. Under heavy or prolonged rainfall, sedimentation basins are prone to rapid siltation, leading to a decrease in their sand interception capacity. If not cleaned in a timely manner, the sand interception function of the sedimentation basins will decline, failing to effectively mitigate soil erosion.

[0003] A current grit removal device for sedimentation tanks includes a support column, a grit pump, and a photovoltaic panel. The support column is installed in the sedimentation tank, and the grit pump is installed at the bottom of the support column to perform grit removal operations periodically. The photovoltaic panel is installed at the top of the support column and is electrically connected to the grit pump to provide power to the pump. Although this grit removal device can remove sludge from the sedimentation tank, the removed sludge is in a slurry form with a high water content, and the sludge is too heavy, making it inconvenient to transport. Utility Model Content

[0004] In view of this, the present invention provides a sludge cleaning device for sedimentation tanks to solve the problem of excessive weight of sludge discharged by sand pumps and inconvenient sludge transportation.

[0005] In a first aspect, this utility model provides a sludge cleaning device for sedimentation tanks, comprising: A dredging assembly, the input end of which is inserted into the sedimentation tank; A mud-water separation assembly, comprising: a separation device and a return pipe, wherein the inlet of the separation device is connected to the output end of the dredging assembly, one end of the return pipe is connected to the separation device, and the other end extends into the sedimentation tank; A transport trolley is positioned below the discharge port of the separation device; A power supply component, which is electrically connected to the dredging component and the mud-water separation component.

[0006] Beneficial effects The dredging unit pumps sludge and water together into a sludge-water separation unit for solid-liquid separation. The separated clean water flows back to the sedimentation tank via a return pipe, significantly reducing the water content of the discharged sludge and placing it in a solid or semi-solid state, thus reducing its weight and improving transportation convenience. Simultaneously, the separated water can be effectively recycled and reused, preventing water waste. A transport trolley collects the separated sludge, enabling automated collection and handling, reducing manual intervention and improving cleaning efficiency.

[0007] In one alternative embodiment, the separation device is a plate and frame filter press.

[0008] Beneficial effects Plate and frame filter presses can fully squeeze out water from sludge under high pressure, significantly reducing the water content of the sludge and transforming it from a fluid slurry into a cake-like solid, facilitating subsequent transportation and stockpiling, and improving sludge treatment efficiency. The separated clear water is returned to the grit chamber through a return pipe, with the return end positioned towards the water surface area. This effectively reduces disturbance to the sediment at the bottom of the chamber, preventing secondary suspension or affecting subsequent settling.

[0009] In one optional implementation, the transport vehicle is equipped with a wireless communication module, which is adapted to control the transport vehicle to transport silt to a designated location along a preset path.

[0010] Beneficial effects The transport vehicle can automatically travel between the separation unit and the storage location according to a preset route, realizing unmanned management of sludge transfer. Through a wireless communication module, the transport vehicle can receive dispatch instructions and report its operating status in real time, thereby avoiding mutual interference and improving transportation efficiency when multiple vehicles are working together.

[0011] In one alternative embodiment, the sedimentation tank sludge cleaning device further includes an intelligent charging chamber, which is connected to the power supply component, and the transport trolley can be connected to the intelligent charging chamber for charging.

[0012] Beneficial effects The intelligent charging compartment can replenish the power of the transport vehicle. When the vehicle's power is low, it can move to the intelligent charging compartment to replenish its power, thereby improving the continuity and autonomy of the dredging operation. The intelligent charging compartment is powered by a power supply unit. The transport vehicle can automatically drive into the charging compartment to replenish its power during work breaks, avoiding mid-operation shutdowns due to insufficient power, improving the stability and operational efficiency of dredging, while reducing the frequency and cost of manual maintenance.

[0013] In one optional embodiment, the sludge removal assembly includes: a sludge pump, a sludge suction pipe, and a sludge discharge pipe. The input end of the sludge pump is connected to one end of the sludge suction pipe, the other end of the sludge suction pipe is inserted into the sedimentation tank, the output end of the sludge pump is connected to one end of the sludge discharge pipe, and the other end of the sludge discharge pipe is connected to the feed inlet.

[0014] In one optional embodiment, the sludge pump is equipped with a controller, the grit chamber is equipped with a sensor, and the controller is electrically connected to the sensor.

[0015] Beneficial effects The sensor can control the start and stop of the sludge pump based on the sludge concentration or turbidity signal in the sedimentation tank, preventing frequent manual operation and improving cleaning efficiency and automation. When the sludge concentration reaches the set threshold, the sludge pump automatically starts to pump out the sludge; when the tank water returns to a clearer state, the sludge pump automatically stops, which not only prevents energy waste caused by excessive pumping, but also avoids reduced separation efficiency due to low concentration operation.

[0016] In one alternative implementation, the sensor is a photosensor.

[0017] Beneficial effects Photosensitive sensors can use changes in the light transmittance of water to reflect sludge concentration or turbidity. When the sludge content in the sedimentation tank increases, causing the water's light transmittance to decrease, the photosensitive sensor's detection signal weakens accordingly. The controller can then automatically start the sludge pump for cleaning based on a threshold. When the water gradually clarifies, the photosensitive sensor signal recovers, and the controller automatically shuts off the sludge pump.

[0018] In one alternative embodiment, the power supply component includes: an energy storage device and a photovoltaic power generation device, wherein the output terminal of the energy storage device is electrically connected to the separation device and the dredging component, and the photovoltaic power generation device is connected to the input terminal of the energy storage device.

[0019] Beneficial effects The power supply component provides a stable power source for the separation and dredging components. Through the energy storage device, it can continuously supply power to the separation and dredging components in the case of insufficient light or at night, ensuring the continuous operation of the separation and dredging components and avoiding operation interruption due to grid instability.

[0020] In one optional embodiment, the photovoltaic power generation device includes: a photovoltaic panel and support columns, four support columns are disposed at the four corners of the photovoltaic panel, the top of the support columns are connected to the bottom surface of the photovoltaic panel, the bottom of the four support columns are connected to the ground, and the photovoltaic panel is located above the energy storage device.

[0021] In one alternative embodiment, the photovoltaic panel is tilted above the energy storage device.

[0022] Beneficial effects The tilted arrangement of photovoltaic panels increases the surface area exposed to sunlight, thereby improving photovoltaic power generation efficiency. At the same time, the tilted installation facilitates natural rainwater washing of the panel surface, reducing dust and also provides some protection for the energy storage device from sun and rain.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other implementations obtained by those skilled in the art based on the embodiments of this utility model without creative effort are also included.

[0027] The following is combined with Figures 1 to 2 The following describes embodiments of the present invention.

[0028] According to an embodiment of the present invention, a sludge cleaning device for a sedimentation tank is provided, comprising: a sludge dredging component, a mud-water separation component 2, a transport trolley 3, and a power supply component. The input end of the sludge dredging component is inserted into the sedimentation tank 6. The mud-water separation component 2 comprises: a separation device 21 and a return pipe. The inlet of the separation device 21 is connected to the output end of the sludge dredging component. One end of the return pipe is connected to the separation device 21, and the other end extends into the sedimentation tank 6. The transport trolley 3 is disposed below the outlet of the separation device 21. The power supply component is electrically connected to the sludge dredging component and the mud-water separation component 2.

[0029] The input end of the sludge removal component is inserted into the bottom of the sedimentation tank 6 to extract the sludge deposited at the bottom. The output end of the sludge removal component is connected to the inlet of the mud-water separation component 2. The mud-water separation component 2 can perform solid-liquid separation on the sludge extracted by the sludge removal component, and it is equipped with a separation device 21 inside. The sludge enters the separation device 21 through the inlet. The separation device 21 can effectively separate the water and sludge in the sludge, reducing the weight of the sludge. The separated clean water flows back to the sedimentation tank 6 through the return pipe, realizing the recycling of water resources. A drainage ditch 61 is opened at the top of the sedimentation tank 6. When the water level in the sedimentation tank 6 is higher than the drainage ditch 61, it can flow into the river through the drainage ditch 61 to prevent water accumulation in the sedimentation tank 6 and sludge overflowing from the sedimentation tank 6.

[0030] The discharge port of the separator 21 is located below the separator 21, and the transport trolley 3 is located below the discharge port of the separator 21. After the separator 21 separates the sludge and water, the mud cake or relatively dry sludge can fall directly into the transport trolley 3 through the discharge port, facilitating subsequent transfer and processing. The power supply component can provide stable power support for the dredging component and the mud-water separation component 2, ensuring the stable operation of the dredging operation.

[0031] The sludge removal component can directly extract sludge from the sedimentation tank 6, avoiding manual labor and reducing labor risks. The mud-water separation component 2 effectively separates the extracted sludge into solid and liquid components, significantly reducing the water content of the discharged sludge, making it easier for the transport trolley 3 to collect and transfer, reducing transportation burden, lowering transportation costs, and improving cleaning efficiency. At the same time, the separated clean water can be returned to the sedimentation tank 6, avoiding water waste.

[0032] In one embodiment, the sludge removal assembly includes a sludge pump 11, a sludge suction pipe 12, and a sludge discharge pipe 13. The input end of the sludge pump 11 is connected to one end of the sludge suction pipe 12, and the other end of the sludge suction pipe 12 is inserted into the grit chamber 6. The output end of the sludge pump 11 is connected to one end of the sludge discharge pipe 13, and the other end of the sludge discharge pipe 13 is connected to the feed inlet.

[0033] Specifically, the other end of the sludge suction pipe 12 is inserted into the bottom area of ​​the grit chamber 6, allowing direct extraction of the sludge deposited at the bottom of the chamber. The sludge discharge pipe 13 transports the sludge pumped by the sludge pump 11 to the separation device 21 for sludge-water separation treatment. The sludge suction pipe 12 is selected with an appropriate length according to the depth of the grit chamber 6 to ensure that it can reach the bottom of the chamber and ensure that the sludge can be fully extracted. Both the sludge suction pipe 12 and the sludge discharge pipe 13 are made of wear-resistant materials and can withstand the fluid erosion of sludge particles.

[0034] In one embodiment, a controller is installed inside the sludge pump 11, and a sensor 14 is installed in the grit chamber 6. The controller is electrically connected to the sensor 14.

[0035] Specifically, the controller can control the start and stop of the sludge pump 11. A sensor 14 is installed in the grit chamber 6, which is electrically connected to the controller to monitor the sludge concentration in the grit chamber 6 in real time. When the sensor 14 detects that the sludge in the grit chamber 6 has reached a preset threshold, it transmits the detection signal to the controller, which automatically drives the sludge pump 11 to start and pump the sludge to the separation device 21 for processing. When the sludge content decreases to the normal range, the controller controls the sludge pump 11 to stop working, realizing intelligent control of the sludge removal process of the grit chamber 6.

[0036] In one embodiment, sensor 14 is a photosensor.

[0037] Specifically, a photosensitive sensor is installed on the inner wall of the grit chamber 6. It outputs an electrical signal based on changes in the light transmittance or turbidity of the grit chamber 6. When the concentration of sludge in the water increases, causing a decrease in light transmittance, the sensor's detection value decreases accordingly; as the water gradually clarifies, the sensor's detection value gradually recovers. The output signal of the photosensitive sensor is transmitted in real time to the controller inside the sludge pump 11. The controller automatically adjusts the start and stop status of the sludge pump 11 according to a set threshold.

[0038] For example, when the detected value is below the preset lower limit, the controller determines that the sludge concentration in the grit chamber 6 is too high and automatically starts the sludge pump 11 to extract the sludge; when the detected value returns to the set upper limit, the controller automatically shuts off the sludge pump 11 to avoid over-extraction. In this way, the photosensitive sensor can achieve dynamic monitoring and automated adjustment of the turbidity of the grit chamber 6, ensuring the timeliness and energy efficiency of the dredging process, while reducing the need for manual intervention.

[0039] In one embodiment, the separation device 21 is a plate and frame filter press.

[0040] Specifically, the plate and frame filter press consists of multiple parallel filter plates and frames arranged alternately, with filter cloth covering the surface of the filter plates to form filtration chambers. The sludge extracted by the sludge removal component enters the feed inlet of the plate and frame filter press through the sludge discharge pipe 13. Under mechanical compression, the filter plates and frames are pressed together, and the sludge is evenly distributed into each filtration chamber. As the pressure gradually increases, water passes through the filter cloth and is discharged as filtrate, which returns to the grit chamber 6 through the outlet and return pipe. The filter cake gradually settles and compacts on the inside of the filter cloth, eventually forming a sludge cake with low moisture content.

[0041] After the filtration cycle is completed, the plate and frame filter press is released, the filter plates separate sequentially, and the sludge cake falls from the discharge port into the transport trolley 3 below under gravity, realizing automatic unloading and transfer of sludge. Through this implementation method, the separation efficiency is high, the sludge cake has a low moisture content, which is convenient for subsequent stacking or resource utilization. At the same time, the returned liquid can re-enter the grit chamber 6 to form a water recycling process, reducing the need for external water replenishment.

[0042] In one embodiment, the transport vehicle 3 is equipped with a wireless communication module, which is suitable for controlling the transport vehicle 3 to transport silt to a designated location along a preset path.

[0043] Specifically, the wireless communication module can interact with the external control system. After the separation device 21 presses the sludge into a sludge cake, the sludge cake is discharged from the discharge port and falls into the transport trolley 3. The transport trolley 3 receives control signals and transports the collected sludge to the designated storage location or treatment area along a preset path.

[0044] The wireless communication module uses a dedicated Wi-Fi wireless communication protocol to ensure a stable communication connection between the transport vehicle 3 and the external control system. Through wireless communication, operators can remotely control the start and stop of the transport vehicle 3 and adjust its route, enabling real-time monitoring of the transportation process and improving transportation efficiency and automation.

[0045] In one embodiment, the sedimentation tank sludge cleaning device further includes a smart charging chamber 5, which is connected to a power supply component, and the transport trolley 3 can be connected to the smart charging chamber 5 for charging.

[0046] Specifically, the intelligent charging compartment 5 is electrically connected to the power supply components, enabling it to replenish the power supply to the transport vehicle 3. After the transport vehicle 3 completes its sludge transport task, it can drive into the intelligent charging compartment 5 under control commands, and the interface between the vehicle body and the charging compartment will connect to achieve power transfer.

[0047] In one embodiment, the power supply component includes: an energy storage device 41 and a photovoltaic power generation device 42. The output terminal of the energy storage device 41 is electrically connected to the separation device 21 and the dredging component, and the photovoltaic power generation device 42 is connected to the input terminal of the energy storage device 41.

[0048] Specifically, the energy storage device 41 provides stable power support for the separation device 21 and the dredging assembly, while the photovoltaic power generation device 42 converts solar energy into electrical energy and stores it in the energy storage device 41. The energy storage device 41 uses a battery pack, the energy capacity of which is configured according to the usage requirements of the dredging assembly and the mud-water separation assembly 2, ensuring that it can still provide sufficient power support for the dredging assembly and the mud-water separation assembly 2 during continuous rainy weather.

[0049] In one embodiment, the photovoltaic power generation device 42 includes: a photovoltaic panel 421 and support columns 422. Four support columns 422 are disposed at the four corners of the photovoltaic panel 421. The top of the support columns 422 is connected to the bottom surface of the photovoltaic panel 421, and the bottom of the four support columns 422 is connected to the ground. The photovoltaic panel 421 is located above the energy storage device 41.

[0050] Specifically, four support columns 422 are respectively installed at the four corners of the photovoltaic panel 421. The top of the support columns 422 is firmly connected to the bottom surface of the photovoltaic panel 421, and the bottom is fixed to the ground, forming a stable support structure. The photovoltaic panel 421 can absorb solar energy and convert it into electrical energy, which is then transmitted to the energy storage device 41 for storage. The energy storage device 41, the dredging component, the mud-water separation component 2, and the intelligent charging compartment 5 are located below the photovoltaic panel 421, which can reduce the overheating problem caused by direct sunlight and extend its service life.

[0051] In one embodiment, the photovoltaic panel 421 is tilted above the energy storage device 41.

[0052] Specifically, the four support columns 422 include two long support columns 422 and two short support columns 422, which make the photovoltaic panels 421 tilted at a certain angle so as to better face the sun and increase the light-receiving area.

[0053] The tilted photovoltaic panel 421 can also utilize rainwater to naturally wash its surface, reducing dust accumulation and maintaining the cleanliness of the photovoltaic panel 421. At the same time, it can also provide shade and rain protection for the energy storage device 41, preventing the energy storage device 41 from being affected by high temperature or rainwater erosion.

[0054] Working process: When the sludge in the grit chamber 6 continues to accumulate and gradually reaches the preset concentration, the sensor 14 transmits the detection result to the controller. After receiving the signal, the controller drives the sludge pump 11 to start. The sludge pump 11 pumps out the sludge at the bottom of the grit chamber 6 and transports it to the mud-water separation component 2 through the sludge discharge pipe 13.

[0055] The sludge-water separation component 2 performs solid-liquid separation on the incoming sludge. The clean water flows back to the sedimentation tank 6 through the return pipe, while the separated solid or semi-solid sludge falls from the discharge port of the separation device 21 into the transport trolley 3. After the transport trolley 3 is filled with sludge, it can travel along a preset path under the command of the control system to transport the sludge to a designated storage point or treatment site.
