Description

Technical Field

[0001] This invention relates to the field of sediment washing technology, and more particularly to a shore-based parallel sediment washing machine. Background Technology

[0002] Endogenous pollution control aims to reduce the pollution load and risk of rivers and lakes by precisely, effectively, and safely removing sediments rich in pollutants (such as nutrients, heavy metals, and organic pollutants). It is a crucial engineering measure in river and lake water environment management. Currently, the mainstream endogenous pollution control methods in China include dredging, sediment solidification, and the addition of microbial agents. Numerous engineering cases and research studies have shown that traditional water conservancy dredging has limited effect on reducing the release of endogenous pollution and faces many subsequent problems, such as large-scale engineering, high investment, difficulty in sludge disposal, and the risk of pollutant resuspension and benthic ecosystem damage. Sediment solidification and the addition of microbial agents, through biochemical methods, pose secondary pollution and biological risks. The new stage of water environment management has spurred the development of more scientific and refined endogenous pollution control technologies, such as environmentally friendly dredging and sediment washing.

[0003] Sediment elution is an in-situ remediation technology for aquatic sediments that uses mechanical, airflow, or liquid flow to generate turbulence, thereby dispersing and separating particles of different sizes. This allows for the in-situ settling and covering of inorganic sediments, while also enabling the ex-situ treatment of fine particulate pollutants. By separating and removing pollutants and suspended particles from the sediment through elution, a mud-water interface with a capping layer of large-particle sediment can be constructed, reducing the release of endogenous pollutants, significantly improving water transparency, and reducing investment and sludge post-treatment issues.

[0004] Currently, the washing unit, power unit, and sewage separation tank of multi-functional bottom sludge washing vessels on the market are all integrated into the hull. Due to the limited depth and hull space, it is difficult to operate in some shallow and narrow water spaces. In addition, factors such as wind and waves, sludge transfer, equipment transportation and assembly on site also restrict the efficiency of construction.

[0005] The existing shore-based separation sediment washing and extraction machine has unsatisfactory operating efficiency and results because the shore channel cannot be moved and the water-based single washing platform lacks power. The shore channel can only be connected in series with a single washing platform. Summary of the Invention

[0012] Preferably, the sedimentation tank is equipped with inclined plate packing inside, and a sludge settling trough is provided on the inner wall of the bottom end of the sedimentation tank, and the sludge settling trough is connected to the sludge pump through a sludge discharge pipe.

[0013] Preferably, the bottom of the washing chamber is open, and two rows of inclined jet nozzles are symmetrically arranged on the inner wall of the top. The interior of the washing chamber is provided with multiple suction ports, and the interior of each suction port is provided with a filter screen.

[0014] Preferably, the top of the washing chamber is provided with a gas inlet and a wastewater outlet, the gas inlet is connected to the jet nozzle, and the wastewater outlet is connected to the suction port.

The air outlet of the aerator is connected to the gas inlet through a gas hose, and the water inlet of the suction pump is connected to the sewage outlet through a hose. The water inlet of the suction pump is also connected to the water inlet of the sewage treatment tank through a hose.

[0016] Preferably, the container is equipped with a primary power distribution cabinet, and the diesel generator is connected to the primary power distribution cabinet via wires. The primary power distribution cabinet can also be directly connected to the mains power.

[0017] Preferably, the first electric agitator, the second electric agitator, the sludge pump, and the screw filter press inside the container are connected to the primary power distribution cabinet via cables to provide electrical power.

[0018] Preferably, the equipment box on the floating platform is equipped with a secondary power distribution cabinet, which is connected to the primary power distribution cabinet via a cable. The winch, suction pump and aerator on the floating platform are connected to the secondary power distribution cabinet via cables to provide power.

[0019] Preferably, the filter cake collecting mechanism includes a filter cake collecting box, and a collecting hopper is fixed above the filter cake collecting box by a support frame. The top of the collecting hopper is aligned with the discharge port of the screw filter press. A crushing mechanism is provided inside the collecting hopper, and a cylindrical quantitative feeding container is provided below the collecting hopper. A measuring inner cylinder is rotatably installed inside the cylindrical quantitative feeding container. The top and bottom of the measuring inner cylinder are both provided with semi-circular concave ends, and the bottom of the cylindrical quantitative feeding container is provided with a semi-circular convex end. The semi-circular concave ends and the semi-circular convex end can form a complete cylindrical cavity. A pressing push plate is provided at one end of the cylindrical cavity, and a sealing and cutting baffle is rotatably installed at the other end of the cylindrical cavity.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] (1) This invention separates the water-based washing platform from the onshore mud-water separation unit. Multiple water-based washing platforms can be set up to work simultaneously, changing the original series process front end to a parallel mode. The onshore processing unit is integrated into a flatbed truck or trailer, which significantly improves the efficiency and flexibility of the equipment for washing bottom mud. This process structure can also achieve different processing capacities by configuring equipment of different specifications. It is applicable to ponds, urban rivers and lakes, and large lakes.

[0022] (2) The present invention integrates the sludge dewatering equipment into the mud-water separation unit. After the sludge is brought ashore, it can be dewatered and reduced in volume to form mud cakes, realizing the fully enclosed treatment of the sludge brought ashore. The sludge dewatering tailwater is returned to the mud-water separation tank to achieve circulation purification and meet the standards for entering the lake, thus achieving the characteristic of no secondary pollution during the construction process.

[0023] (3) The present invention further refines the design of the filter cake collection mechanism. By integrating crushing, quantitative extrusion, and automatic cutting into a single structure, the filter cake is standardized. The mechanism crushes large pieces of filter cake by the opposite rotation of two crushing rollers, avoiding clumping and blockage. It uses the measuring inner cylinder to accurately feed the filter cake quantitatively, and the extrusion pusher presses the filter cake into shape. Then, through the linkage of the sealing and cutting baffle and the transmission structure, the filter cake is automatically cut into segments to form block filter cakes of uniform specifications. At the same time, the linkage design of motor, lead screw and cylinder is adopted to realize the full automation of filter cake preparation without manual intervention. This not only ensures the consistency of filter cake quality, but also greatly reduces the intensity of manual operation. The standard-sized filter cakes are easier to stack and store, effectively saving storage space, and are not easy to scatter during transportation, improving the convenience of subsequent disposal.

Detailed Implementation

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example 1

[0048] Reference Figure 1-7 A shore-based parallel sediment washing and dewatering machine, the core of which includes multiple sets of water-based washing and dewatering platforms and a shore-based mud-water separation unit, realizes the core architecture of multi-platform parallel washing and dewatering and centralized shore-based processing.

[0049] The floating platform uses a fiberglass floating platform 2 as its carrier. The platform has a hollow area, and a winch 202 is fixed above the hollow area by a bracket 201. The washing chamber 3 is installed inside the hollow area. The steel cable of the winch 202 is fixed to the top of the washing chamber 3. The washing chamber 3 can be raised and lowered by raising and lowering the steel cable, so as to achieve precise control of the washing depth of the bottom sediment. The floating platform 2 is equipped with a propeller, which can move freely on the water surface. It is equipped with a high-precision GPS positioning device and a platform PLC controller to ensure accurate positioning and automated control of the working area.

[0050] The shore-based sludge-water separation unit is integrated into a standard container 1. Container 1 is equipped with hydraulic outriggers 101, which can quickly level uneven ground. The entire unit can be mounted on a flatbed truck or trailer for mobile transport. The unit includes a sewage treatment tank 4, a screw filter press 5, a filter cake collection mechanism 6, and a diesel generator 7. The sewage treatment tank 4 is made of thickened fiberglass or carbon steel. Its inlet 408 is connected to each floating platform 2 through a pipe. The sludge discharge port at the bottom is connected to a sludge pump 409. The sludge outlet of the sludge pump 409 is connected to the screw filter press 5 through a telescopic hose.

[0051] Work process: The operator manipulates the floating platform 2 to the target water area, and uses the winch 202 to lower the washing and desliming chamber 3 to the bottom sediment layer of the riverbed. After the bottom sediment is disturbed, it is pumped to form a mud-water mixture, which is then transported through pipelines to the shore-based sewage treatment tank 4. Coagulant is added to the sewage treatment tank 4 to achieve horizontal sedimentation. The settled sludge is transported by the sludge pump 409 to the screw filter press 5 for dewatering. The filter press tailwater is returned to the sewage treatment tank 4 for secondary flocculation to ensure that it meets the discharge standards. The mud cake formed after dewatering is stored in the filter cake collection mechanism 6 and transported off-site periodically. The clean water treated in the sewage treatment tank 4 is returned to the surrounding water bodies through pipelines to realize the recycling of water resources.

[0052] Example 2

[0053] Reference Figure 1-7 Based on Example 1, this embodiment further subdivides the wastewater treatment tank 4 of the sludge-water separation unit to improve sludge-water separation efficiency and treatment stability. The core improvements are as follows:

[0054] The wastewater treatment tank 4 adopts a segmented design, with a chemical dosing tank 401, an intermediate mixing tank 405, a sedimentation tank 406, and a clear water tank 407 arranged sequentially along the water flow direction, forming a closed-loop treatment chain from chemical dosing, mixing, sedimentation to clear water recycling.

[0055] The dosing tank 401 is equipped with a coagulant mixing tank 403 at the top and a first electric agitator 402 is installed in the tank body; the intermediate mixing tank 405 is equipped with a second electric agitator 404. The two tanks are connected by overflow to guide the mud and water. The intermediate mixing tank 405 is connected to the sedimentation tank 406 and the sedimentation tank 406 is connected to the clear water tank 407 by overflow to ensure a smooth water flow transition. The clear water in the clear water tank 407 is directly returned to the water body by a water pump.

[0056] Key optimization: The sedimentation tank 406 is lined with honeycomb inclined plate packing 4062, which increases the effective sedimentation area, improves the removal efficiency of suspended solids, and shortens the sedimentation time.

[0057] The inner wall of the pool is equipped with a sludge settling tank 4061. The settled sludge is collected by the sludge discharge pipe to the sludge pump 409 and finally transported to the screw filter press 5 for treatment, so as to avoid the sludge from accumulating at the bottom of the pool and causing a decrease in treatment efficiency.

[0058] Example 3

[0059] Reference Figure 1-7 Based on Example 2, this embodiment further refines the elution operation structure of the water-based elution platform and improves the power supply scheme for the entire system, enhancing operational efficiency and adaptability to complex environments. The core improvements are as follows:

[0060] 1. Optimized washing and desliming chamber structure: The bottom of the washing and desliming chamber 3 is open, and two rows of inclined jet nozzles 304 are symmetrically arranged on the inner wall of the top, with the inclination angle adapted to the range of bottom mud disturbance; multiple suction ports 303 are opened inside the chamber, and the suction ports 303 have built-in filters 3031 to prevent large particles of debris from clogging the pipes.

[0061] The washing and desorption chamber 3 is equipped with a gas inlet 302 and a sewage outlet 301 at its top, which are connected to the jet nozzle 304 and the suction port 303 respectively. The floating platform 2 is equipped with an equipment box 10 at its top, which contains a suction pump and an aerator. The aerator outlet is connected to the gas inlet 302 through a gas hose, and the suction pump inlet is connected to the sewage outlet 301 through a hose and extends to the inlet 408 of the sewage treatment tank 4.

[0062] An online turbidity meter is installed at the inlet of the suction pump to monitor the turbidity of the mud and water in real time, providing data support for adjusting the dosage of chemicals.

[0063] During operation, the jet nozzle 304 sprays high-pressure air to disturb the bottom sediment and form a mud-water mixture, which is then quickly sucked out through the suction port 303. Multiple floating platforms can operate simultaneously in parallel, greatly improving the efficiency of bottom sediment treatment.

[0064] 2. Dual-mode power supply system: A primary power distribution cabinet is installed inside container 1, and the diesel generator 7 is connected to the primary power distribution cabinet by wires. At the same time, the primary power distribution cabinet is reserved with a mains power access interface to realize a dual power supply mode with mains power priority and diesel generator backup.

[0065] The first electric agitator 402, the second electric agitator 404, the sludge pump 409, and the screw filter press 5 inside the container are all connected to the primary power distribution cabinet via cables.

[0066] The equipment box 10 of the floating platform 2 is equipped with a secondary power distribution cabinet, which is connected to the primary power distribution cabinet via cables. Waterborne equipment such as the winch 202, suction pump, and aerator are all powered by the secondary power distribution cabinet. This design ensures continuous and stable operation of the equipment in remote waters without mains power coverage or in the event of a sudden power outage, adapting to various operational needs.

[0067] Example 3

[0068] Based on embodiment 2, this embodiment further refines the filter cake collection mechanism 6. The filter cake collection mechanism 6 includes a filter cake collection box 601. A collection hopper 801 is fixed above the filter cake collection box 601 by a support frame 8. The top of the collection hopper 801 is aligned with the discharge port of the screw filter press 5. A crushing mechanism is provided inside the collection hopper 801, and a cylindrical quantitative feeding container 804 is provided below the collection hopper 801. A measuring inner cylinder 8041 is rotatably installed inside the cylindrical quantitative feeding container 804. The top and bottom of the measuring inner cylinder 8041 are both provided with semi-circular concave 8042, and the bottom of the cylindrical quantitative feeding container 804 is provided with a semi-circular convex 8044. The semi-circular concave 8042 and the semi-circular convex 8044 can form a complete cylindrical cavity. One end of the cylindrical cavity is provided with a pressing push plate 9, and the other end of the cylindrical cavity is provided with a rotatably installed sealing and cutting baffle 901.

[0069] The crushing mechanism includes two parallel crushing rollers 802, crushing blades 8021 arranged interlaced on the outside of the two crushing rollers 802, and gears 8022 fixed on each of the two crushing rollers 802. The two gears 8022 mesh with each other. One of the crushing rollers 802 is driven to rotate by a first rotary motor 803. When the first rotary motor 803 is turned on, the two crushing rollers 802 can be driven to rotate synchronously in opposite directions through the meshing transmission between the two gears 8022, thereby crushing the filter residue that falls into the collection hopper 801 and dropping it to the bottom of the collection hopper 801.

[0070] The bottom end of the collecting hopper 801 is connected to the cylindrical quantitative feeding container 804. When the semi-circular concave 8042 of the measuring inner cylinder 8041 is aligned with the bottom feeding port of the collecting hopper 801, the crushed filter residue falls into the semi-circular concave 8042. The measuring inner cylinder 8041 is driven to rotate by the second rotary motor 8043. After rotating approximately 80 degrees, the other semi-circular concave 8042 can be aligned with the bottom feeding port of the collecting hopper 801, and the crushed filter residue will be transferred to the semi-circular convex 8044. 2 and the semi-circular outward protrusion 8044 can form a complete cylindrical cavity. One end of the cylindrical cavity is sealed by the sealing and cutting baffle 901, and then the filter residue is squeezed by the extrusion push plate 9, so that the filter residue is combined into blocks. Then, with the sealing and cutting baffle 901 rotating and misaligned with the discharge end opening, the squeezed filter residue can be pushed out. By rotating the sealing and cutting baffle 901 again, the long section of filter residue can be cut into blocks to form a standard-shaped filter cake, which can save more storage space and is more convenient for storage and subsequent transfer and transportation.

[0071] To drive the extrusion pusher 9 and the sealing and cutting baffle 901 to move and compress and cut the filter residue, a first fixed frame 902 and a second fixed frame 903 are fixed at the bottom of the cylindrical quantitative feeding container 804. A lead screw 906 is rotatably installed between the first fixed frame 902 and the second fixed frame 903. A U-shaped connecting rod 904 is fixed on the extrusion pusher 9. The lower horizontal section of the U-shaped connecting rod 904 passes through the first fixed frame 902 through the guide hole and is fixed with a horizontal moving part 905. The lead screw 906 passes through the horizontal moving part 905 through the threaded hole, and the horizontal moving part 905 is driven to rotate by a third rotary motor 9061. When the third rotary motor 9061 is turned on, it can drive the lead screw 906 to rotate and drive the horizontal moving part 905 to move horizontally, thereby driving the extrusion pusher 9 to move horizontally and compress the filter residue through the U-shaped connecting rod 904.

[0072] A transmission cylinder 9011 is rotatably mounted between the first fixed frame 902 and the second fixed frame 903. The transmission cylinder 9011 has continuously formed horizontal sliding grooves 9012 and helical sliding grooves 9013 on its outer surface. A sliding limit rod 9051 is fixed to the top of the horizontal moving part 905, extending into the horizontal sliding groove 9012. A polygonal sleeve 9014 is fixed to one end of the transmission cylinder 9011. A polygonal pin 9015 is fixed to the sealing and cutting baffle 901, extending into the polygonal sleeve 9014. A return spring 9016 is connected between the polygonal pin 9015 and the inner wall of the polygonal sleeve 9014. A locking cylinder 9017 is installed on the second fixing frame 903. The output of the locking cylinder 9017 is fixed with a locking pin. When the locking cylinder 9017 extends, it can be inserted into the polygonal sleeve 9014 and into the corresponding positioning hole on the polygonal pin 9015, preventing the polygonal pin 9015 from sliding horizontally relative to the polygonal sleeve 9014. At this time, the sealing and cutting baffle 901 is in close contact with the side wall of the quantitative feeding container 804 and is in a sealing state.

[0073] First, the horizontal moving part 905 moves towards the second fixed frame 903, driving the drive extrusion push plate 9 to move and compress the filter residue. The sliding limit bar 9051 slides within the horizontal sliding groove 9012, the transmission cylinder 9011 remains stationary, and the two degrees of freedom of rotation and horizontal movement of the sealing and cutting baffle 901 are restricted, maintaining the sealing state. When the sliding limit bar 9051 moves close to the position of the spiral groove 9013 (a laser sensor can be installed at this position), the controller controls the locking cylinder 9017 to automatically shorten and release the lock, allowing the sealing and cutting baffle 901 to move horizontally relative to the transmission cylinder 9011. At this time, the sliding limit bar 9051 continues to move, pushing the sealing and cutting baffle 901 to move horizontally, causing the compressed filter residue to be pushed out. When the material moves to the position of the spiral slide 9013, it will drive the transmission cylinder 9011 to rotate. At this time, it will drive the sealing and cutting baffle 901 to rotate. The sealing and cutting baffle 901 first rotates to a position that is offset from the discharge port. Then, the return spring 9016 pulls the sealing and cutting baffle 901 to reset. Then, the sealing and cutting baffle 901 continues to rotate, which can cut the filter residue. During the cutting process, the sealing and cutting baffle 901 will continue to be pushed horizontally by the material. When the cutting is completed, it will continue to reset and cut off a piece. In this way, the cutting can be continuously performed. After the cutting is completed, the extrusion push plate 9 is controlled to move back to reset, and the locking cylinder 9017 extends again to lock the horizontal movement freedom of the sealing and cutting baffle 901, switching to the sealing state, thus preparing for the next compression and cutting, thereby achieving the purpose of automatic segmented cutting.
