[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please see Figures 1-8 This invention provides a technical solution for a floating mud-water separation device for discharging mud water: Example

[0018] The embodiment provides a floating sludge-water separation device for sludge water, and mainly solves the problems of fixed installation and limited water area range of traditional sludge-water separation equipment, and realizes flexible treatment of sludge water in different water areas such as rivers, lakes and ponds through floating design. The overall structure comprises a floating ring 1 and a sludge-water separation device 3. The floating ring 1 is made of high-density polyethylene material and has a ring structure. The buoyancy of the floating ring 1 can be adjusted according to the weight of the sludge-water separation device 3, so that the overall device can stably float on the water surface. The floating ring 1 is fixedly connected to the outer side wall of the sludge-water separation device 3 through a connecting rod 2. The connecting rod 2 is made of stainless steel, which can ensure the connection strength and resist water corrosion. The device is supported on the water surface by the floating ring 1, and does not need to be pre-installed. The height of the device can be automatically adjusted according to the water level, and the device is suitable for water areas with different depths and can be easily moved to different operation points. The connecting rope 6 can be bound on the floating ring 1 to limit the movement range of the device to prevent the device from being lost.

[0019] The sludge-water separation device 3 is a cylindrical shell structure, and the inside thereof is divided into a center area and an annular treatment area by an inner ring plate 7. The center area is divided into a plurality of independent functional areas by a partition plate 8, including a sludge-water entering area 301, a sludge-water discharging area 306, a sludge discharging area 307, a clean water area 305 and a pump installation area. The areas are connected in sequence through water flow paths to realize the whole process treatment of sludge water from entering to purifying and discharging. Figure 4 and Figure 5 As shown in the specific embodiments, the sludge-water entering area 301 is located on one side of the center area and is connected with the external water area through a water inlet pipe 4. A submersible pump 5 is installed at the bottom end of the water inlet pipe 4. When the submersible pump 5 works, the sludge water in the external water source is pressurized and pumped into the sludge-water entering area 301. In order to prevent garbage and other sundries from entering the submersible pump 5, a grid net or other interception structure is arranged at the input port of the submersible pump 5.

[0020] The annular treatment area is located on the outside of the center area and provides an annular flow path for sludge water. The annular treatment area is divided into a sedimentation area 308 and a sedimentation area 309. The sedimentation area 308 is close to the sludge-water entering area 301 and is connected with the sludge-water entering area 301. The sedimentation area 309 is close to the sludge-water discharging area 306 and is connected with the sludge-water discharging area 306, so as to form a flow path and a treatment process of flocculation sedimentation and sedimentation separation. Figure 5As shown, the precipitation unit is arranged in the precipitation area 308, including a plurality of evenly arranged spray pipes 11 and a flocculation liquid pump 13, and a flocculation liquid storage area 303 separated by a partition plate 8. The flocculation liquid pump 13 is installed in the pump installation area 302, and the input and output ends of the flocculation liquid pump 13 are connected with flocculation liquid pipes 14. The end of the input flocculation liquid pipe 14 extends into the flocculation liquid storage area 303, and the output flocculation pipe is connected with each spray pipe 11. The flocculation liquid pump 13 draws the flocculant from the storage area through the flocculation liquid pipe 14, and uniformly injects it into the sludge water in the precipitation area 308 through the spray pipe 11. After the flocculant is mixed with the sludge water, the micro-particle is coagulated into large flocs through adsorption, and the precipitation is accelerated. The precipitated water and sediment flow through the precipitation area 308 and finally flow to the sludge discharge area 306.

[0021] The spiral guide vane 12 is also installed in the precipitation area 308 through the rotating shaft. When the sludge water flows in the annular treatment area, the spiral guide vane 12 is rotated by the water flow. On the one hand, the sludge water is agitated to fully mix the flocculant with the sludge water. On the other hand, the spiral water flow is formed to guide the sludge water to flow along the annular path. A plurality of grid plates 29 are arranged in the settling area 309. When the water flow passes through the grid plate 29, the flow rate is reduced to make the sediment gravity precipitate, realizing the depth separation of water and sediment.

[0022] The water and sediment treated by the settling area 309 enter the sludge discharge area 306. The partition plate 8 between the sludge discharge area 306 and the clean water area 305 is a filter plate 9 with a pore size of 0.5-1 mm. The filter plate 9 further filters the fine particles remaining in the water, so that the clean water enters the clean water area 305. The drainage pump 17 is installed in the pump installation area 304 of the device. The input and output ends of the drainage pump 17 are connected with drainage pipes 18. The input drainage pipe 18 extends into the clean water area 305, and the output drainage pipe 18 extends outside the device. The clean water is directly discharged to the outside through the drainage pipe 18, realizing the separation and discharge of the water in the sludge water. The sludge discharge equipment 19 is installed in the sludge discharge area 307 of the device, and is connected with the sludge discharge area 306 to discharge the sediment and sludge separated from the sludge discharge area 306 outside the device.

[0023] In practical use, this invention provides a floating mud-water separation device for discharging muddy water. The device is deployed to the target water area requiring mud-water discharge. A float ring 1 provides buoyancy, allowing the device to float on the water surface. An inlet pipe 4 extends below the water surface. A submersible pump 5 is activated, drawing muddy water from the water area into a mud-water inlet zone 301. The muddy water is then pushed into a sedimentation zone 308 in a ring-shaped treatment zone. A flocculant pump 13 draws flocculant from a flocculant storage zone 303 into a spray nozzle 11. The spray nozzle 11 sprays the flocculant into the sedimentation zone 308, injecting flocculant into the muddy water in the sedimentation zone 308. During the flow of mud and water, the spiral guide vanes 12 rotate, causing the mud and water to mix with the flocculant. The mud and water flow along a circular path and complete the initial sedimentation. The settled water and sediment enter the settling zone 309, where the grid plate 29 reduces the flow velocity, allowing small particles to settle further. Then, the settled water enters the mud and water discharge zone 306 and passes through the filter plate 9 into the clean water zone 305. The separated clean water is discharged by the drainage pump 17, while the settled mud remains in the mud and water discharge zone 306. The mud discharge equipment 19 discharges the mud to a designated location on the bank via the mud discharge pump 27 and the mud discharge pipe 28. Example

[0024] Based on Example 1, such as Figures 6-8 As shown in the figure, this embodiment provides a detailed description of the structure of the sludge discharge device 19.

[0025] The sludge removal equipment 19 mainly includes a filter box 20, in which a second filter plate 10 is horizontally arranged. The filter plate 10 has a pore size of 0.1-0.3mm. The filter box 20 is divided into upper and lower layers by the filter plate 10: the upper layer is a sludge chamber for collecting sludge from the sludge discharge area 306, and the lower layer is a drainage chamber for collecting filtered water. The bottom of the drainage chamber is connected to a water outlet pipe 31, and a solenoid valve 30 is installed on the water outlet pipe 31, which can be opened at regular intervals to discharge the filtered water and prevent water accumulation in the drainage chamber from affecting the filtration efficiency of the second filter plate 10. The sludge chamber is divided into two areas, A and B, by a baffle 21 to achieve an alternating working mode: when one area is discharging sludge, the other area can continue to collect sludge. The filter box has connection boxes at both ends. The connection boxes are connected to areas A and B through outlet 23. A three-way pipe 26 is connected to the outside of the filter box. Two of the joints of the three-way pipe 26 are connected to the two outlets 23 on the connection box, and the other joint is connected to the mud and water inlet area 301 or the input end of the mud discharge pump 27. That is, one end of the three-way pipe is connected to the mud and water inlet area 301, and the other end of the three-way pipe is connected to the mud discharge pump 27. The output end of the mud discharge pump 27 is connected to the mud discharge pipe 28. The mud discharge pipe 28 extends out of the device and is connected to the mud and sewage treatment equipment on the bank through a conveying pipeline.

[0026] The valve assembly controls the opening and closing of outlets 23 in areas A and B. It mainly includes a sealing block 24 that slides within the connecting box. The sealing block 24 is located within the connecting line near the sludge pump 27, and a magnet is embedded within it. Electromagnets 25 are symmetrically fixed to the inner walls on both sides of the connecting box. When the left electromagnet 25 is energized, it attracts the sealing block 24, causing it to move to the left, blocking outlet 23 in area A and opening outlet 23 in area B. Sludge from area B is then discharged through the sludge pump 27. The opposite occurs when the right electromagnet 25 is energized. By controlling the alternating sludge discharge between the two areas through the valve assembly, when area A is discharging sludge, area B suspends sludge discharge, and the sludge accumulates in area B and cannot be discharged. When sufficient sludge accumulates, the sealing block 24 shifts position, the accumulated sludge in area B is discharged, and area A begins collecting sludge. This method ensures that the sludge pump 27 is always in a sludge-discharging state, avoiding idling, and also extends the residence time of the sludge in the filter box, further removing residual water from the sludge and improving the sludge-water separation effect.

[0027] In practical use, the floating mud-water separation device of the present invention for discharging mud and water has the following characteristics: when the sealing block 24 is attracted by the electromagnet 25 to block the outlet 23 of area B, the mud pump 27 discharges the mud from area A through the three-way pipe 26, and the mud in area B is intercepted and further separated by the filter plate 10; after area B is full of mud, the electromagnet 25 switches on and off, the sealing block 24 slides and blocks area A, and mud begins to enter and be filtered in area A. At the same time, the mud filtered in area B begins to be discharged. This cycle is repeated to make the mud discharge process continuous and without interruption. Example

[0028] Based on Example 1, such as Figure 3 As shown, a retaining strip 16 is installed at the junction of the mud and water inlet zone 301 and the annular treatment zone. A filter frame 15 is installed at the junction by the retaining strip 16. The side of the filter frame 15 facing the water inlet pipe 4 is open to facilitate the entry of mud and water. The top is sealed to prevent the mud and water from overflowing. The remaining frame walls are evenly distributed with filter holes of 5-10mm. The filter frame 15 can first intercept large particles of impurities such as branches and stones in the water to avoid clogging of subsequent equipment.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
