Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of riverbed sediment treatment, and specifically relates to a device for preparing greening soil using riverbed sediment dredged and a method for using the device. Background Art
[0002] When the river is desilted and dredged, a large amount of high-water content sediment will inevitably be produced. If it is not treated, it will not only cause environmental pollution, but also occupy a large amount of land resources. Therefore, the post-treatment of sediment is crucial in the desilting project. The dredged sediment of the river is rich in "nitrogen and phosphorus" nutrients and has a good land utilization resource nature. After dehydration, the sediment can be used for greening or soil improvement, which can realize the benign closed loop of the last kilometer of the desilting project and has significant economic and ecological benefits. At present, there is a method of preparing greening soil by dredging sediment, which can simultaneously dehydrate and ferment the sediment, reduce construction time and reduce costs.
[0003] For example, the Chinese invention patent with patent application number "CN202211565690.6" discloses a method for preparing greening soil by dehydrating and synchronously fermenting geotube bags of dredged mud from rivers and lakes. In this method, "a special conditioner for mud fermentation is directly added to the mud pipe to ensure that the fermentation material and the mud are fully mixed. A high-strength PVC air supply branch pipe is laid in the mud of the geotube bag. On the one hand, it can ventilate the mud in the later fermentation, and on the other hand, it can serve as a permeable support material at the bottom of the geotube bag." This patent realizes the simultaneous dehydration and fermentation of the mud, effectively shortening the entire process cycle from dredging mud to greening soil.
[0004] However, this patent has shortcomings. Since the air supply branch is arranged at the bottom of the outer side of the geotextile tube, when the air supply branch delivers air to the inside of the geotextile tube, it is difficult for the air to pass through the dredged sludge and reach the top of the geotextile tube. Therefore, the dredged sludge at the bottom of the geotextile tube has more contact with the air, while the dredged sludge at the top has less contact with the air, which leads to uneven aerobic fermentation speed of the dredged sludge at different positions.

DETAILED DESCRIPTION
[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0041] See also Figure 1-18 The present invention provides a technical solution: a device for preparing green soil using river dredged sludge, comprising an assembly ring 1, a first geotextile tube bag 2, a second geotextile tube bag 3, two assembly plates 5 and an air supply assembly 6. Figure 2-3 , the top and bottom surfaces of the assembly ring 1 are provided with assembly grooves 12, the first geotube bag 2 and the second geotube bag 3 are respectively fixed in the assembly grooves 12 at the top and bottom of the assembly ring 1, and the first geotube bag 2, the assembly ring 1 and the second geotube bag 3 are jointly enclosed to form a receiving chamber 4. A feed port 21 is provided on the first geotube bag 2, and the dredged sludge to be dehydrated and fermented will be filled in the receiving chamber 4 through the feed port 21, and the dredged sludge will not overflow from the connection between the assembly ring 1 and the two geotube bags. The first geotube bag 2 and the second geotube bag 3 need to be destroyed after the dredged sludge is dehydrated and fermented to form green soil, while the assembly ring 1, the two assembly plates 5 and the air supply assembly 6 can be recycled. The two assembly plates 5 are respectively arranged in the two assembly ports 11 on both sides of the assembly ring 1. The air supply assembly 6 includes a first air blowing assembly 61 and a second air blowing assembly 62 . The first air blowing assembly 61 and the second air blowing assembly 62 are respectively arranged on two assembly plates 5 , and the air outlet ends thereof extend into the accommodating cavity 4 .
[0042] In the present invention, the structures of the first geotube bag 2 and the second geotube bag 3 are mirror-symmetrical, so the assembly ring 1 is located in the middle of the first geotube bag 2 and the second geotube bag 3. Therefore, when the first blowing assembly 61 and the second blowing assembly 62 convey air into the accommodating chamber 4, the dredged sludge at the top and the bottom can fully contact with the air, ensuring that the aerobic fermentation speed of the dredged sludge at different positions is uniform.
[0043] See also Figure 5 The first air blowing assembly 61 includes a first air blowing pipe 611, and a plurality of evenly distributed first air blowing holes 6111 are provided at the top and bottom of the first air blowing pipe 611, a separation net 63 is provided in the first air blowing hole 6111, and an air inlet branch 64 is provided in the middle of the first air blowing pipe 611. The second air blowing assembly 62 includes a second air blowing pipe 621, and a plurality of evenly distributed second air blowing holes 6211 are provided at the top and bottom of the second air blowing pipe 621, a separation net 63 is also provided in the second air blowing hole 6211, and an air inlet branch 64 is also provided on the second air blowing pipe 621. The first air blowing pipe 611 and the second air blowing pipe 621 can transport air in two directions through the first air blowing holes 6111 and the second air blowing holes 6211, so that the dredged bottom mud at the top and bottom of the accommodating chamber 4 can fully contact with the air. The separation net 63 can prevent the dredged bottom mud from falling into the first air blowing hole 6111, thereby preventing the first air blowing hole 6111 from being blocked.
[0044] See also Figure 1 , Figure 5-6 and Fig.18There are several air supply components 6. The middle of the first air blowing pipe 611 and the middle of the second air blowing pipe 621 are connected to the first end of an air inlet branch pipe 64 respectively. The middle of the air inlet branch pipe 64 is rotatably connected to the assembly plate 5. The second end of the air inlet branch pipe 64 extends out of the accommodating cavity 4. A worm gear 65 is fixedly arranged on the second end of the air inlet branch pipe 64. When the worm gear 65 rotates, the first air blowing pipe 611 and the second air blowing pipe 621 can be driven to rotate through the air inlet branch pipe 64, which can not only change the direction of the blown air, but also stir the dredged sludge and promote the aerobic fermentation of the dredged sludge.
[0045] See also Figure 1 , Figure 7-9 and Fig.18 The present invention also includes two control components 7, which include a carrying box 71, a rotating drive component 72, a pull plate 73, a plurality of support legs 74 and a plurality of universal wheels 75. The side wall of the carrying box 71 facing the assembly plate 5 is provided with a plurality of observation channels 711. Figure 2 and Figure 4 The assembly plate 5 is provided with a plurality of observation windows 51, and the observation windows 51 correspond to the positions of the observation channels 711. The material of the observation windows 51 can be tempered glass, and the operator can see the observation windows 51 through the observation channels 711, and can see the dehydration and fermentation status of the dredged sludge in the accommodation chamber 4 through the observation windows 51.
[0046] See also Figure 7 and Fig.18 The rotation drive assembly 72 is arranged in the carrying box 71, and is used to drive the worm gear 65 to rotate. The middle part of the pull plate 73 is fixedly connected to the carrying box 71, and the two ends of the pull plate 73 are respectively fixedly connected to the two ends of the assembly plate 5. A plurality of support legs 74 are fixedly arranged on the bottom surface of the carrying box 71, and a universal wheel 75 is arranged at the bottom of the support legs 74. Pulling the pull plate 73 can drive the entire control assembly 7 to move, thereby driving the assembly plate 5 and the air supply assembly 6 thereon to move together.
[0047] See also Figure 1 When the control assembly 7 is moved to insert the assembly plate 5 into the assembly opening 11, the accommodating chamber 4 is not connected to the outside, and the air outlet ends of the first blowing assembly 61 and the second blowing assembly 62 extend into the accommodating chamber 4. Fig.18 When the manipulation assembly 7 is moved to make the assembly plate 5 leave the assembly opening 11 , the accommodating chamber 4 is connected with the outside through the assembly opening 11 , and the first blowing assembly 61 and the second blowing assembly 62 leave the accommodating chamber 4 .
[0048] See also Figure 1 and Figure 16-18The present invention also includes a pressure water guide assembly 8, which includes a support plate 81, a plurality of first water guide rods 82, a pressure plate 83, a plurality of second water guide rods 84 and a plurality of straps 85. The support plate 81 is arranged below the second geotube bag 3, and the support plate 81 supports the second geotube bag 3 through a plurality of first support strips 811 at the top, and the support plate 81 does not contact the second geotube bag 3. The pressure plate 83 is arranged above the first geotube bag 2, and the pressure plate 83 applies pressure to the first geotube bag 2 through a plurality of second support strips 831 at the bottom, and the pressure plate 83 does not contact the first geotube bag 2. A plurality of straps 85 are evenly distributed at both ends of the pressure plate 83, the top of the strap 85 is fixedly connected to the pressure plate 83, and the bottom of the strap 85 is detachably connected to the support plate 81, and the strap 85 is an elastic band. When the support plate 81 and the pressure plate 83 are connected together by the strap 85, the strap 85 is in an extended state to store elastic potential energy. Therefore, the strap 85 can apply pressure to the second geotube bag 3 and the first geotube bag 2 through the support plate 81 and the pressure plate 83 to accelerate the dehydration speed of the dredged sludge in the containing chamber 4.
[0049] See also Figure 14-15 A first drainage channel 812 is formed between two adjacent first support bars 811, and a plurality of first water guide rods 82 are respectively disposed in the plurality of first drainage channels 812. Figure 16-17 A second drainage channel 832 is formed between two adjacent second support bars 831, and a plurality of second water guide rods 84 are respectively arranged in the plurality of second drainage channels 832. When dredging the bottom mud and dehydrating it, water will seep out from the surface of the first geotube bag 2 and the second geotube bag 3. Since the first support bars 811 and the second support bars 831 actually apply pressure, the seeped water will flow into the first drainage channel 812 and the second drainage channel 832. The first water guide rod 82 and the second water guide rod 84 can play a role in horizontal drainage, guiding the water in the first drainage channel 812 and the second drainage channel 832 to be quickly discharged in the horizontal direction.
[0050] See also Fig.15 The cross section of the first water guide rod 82 is a diamond shape, and the middle of the first water guide rod 82 is lower than the top of the first support bar 811, so the first water guide rod 82 will not contact the second geotube bag 3 and will not scratch the second geotube bag 3. Both ends of the first water guide rod 82 extend out of the first drainage channel 812. When water enters the first drainage channel 812, it will adhere to the first water guide rod 82 and flow along the outer surface of the first water guide rod 82 to both ends. The first water guide rod 82 with a diamond cross section can ensure that the water attached to it can converge to the bottom. When the water flows to the two ends of the first water guide rod 82, it will drip downward. At this time, the water flow has left the first drainage channel 812.
[0051] See also Fig.17The structure of the second water guide rod 84 is the same as that of the first water guide rod 82. The middle part of the second water guide rod 84 is higher than the bottom part of the second support bar 831. Therefore, the second water guide rod 84 will not contact the first geotube bag 2 and will not scratch the first geotube bag 2. When water enters the second drainage channel 832, it will adhere to the second water guide rod 84 and flow along the outer surface of the second water guide rod 84 to both ends. When the water flows to both ends of the second water guide rod 84, it will drip downwards. At this time, the water flow has left the second drainage channel 832. Two cloths and one membrane can be laid under the support plate 81 to guide the water discharged from the first drainage channel 812 and the second drainage channel 832 to the ditch to achieve the recycling of water resources.
[0052] See also Figure 1 and Figure 7-9 The control assembly 7 further includes a water baffle 76 and a water diversion assembly 77. The water baffle 76 is provided with a water guide slope 761, which is located below the end of the second water guide rod 84. When water drips downward from both ends of the first water guide rod 82, it will fall on the water guide slope 761 and slide down along the water guide slope 761, which can prevent the falling water from falling into the carrying box 71 and prevent the rotating drive assembly 72 from contacting with water. There is a gap between the carrying box 71 and the assembly plate 5, and the water diversion assembly 77 is arranged between the carrying box 71 and the assembly plate 5. Water sliding down from the water guiding slope 761 will fall between the supporting box 71 and the assembly plate 5, and a number of air intake branch pipes 64 are in this position. The water distribution assembly 77 can isolate the sliding water from the air intake branch pipes 64 to prevent the air intake branch pipes 64 from contacting the water. Therefore, water will not enter the supporting box 71 from the connection between the air intake branch pipes 64 and the supporting box 71, further preventing the rotating drive assembly 72 from contacting the water.
[0053] See also Figure 1 , Figure 5 , Figure 7 , Fig.10 and Fig.18 , the air supply assembly 6 also includes a rotating sealing sleeve 66 and an air pipe 67. The middle part of the air pipe 67 is fixedly connected to the water baffle 76, and the first end of the air pipe 67 is connected to the second end of the air inlet branch pipe 64 through the rotating sealing sleeve 66. When the present invention is in use, the second ends of a plurality of air pipes 67 can be connected to the same air supply main pipeline, and the air supply main pipeline conveys air to the air inlet branch pipe 64 through the air pipe 67, and then conveys air to the dredged sludge in the accommodating chamber 4 through the first blowing pipe 611 and the second blowing pipe 621. Since the rotary drive assembly 72 drives the worm gear 65 to rotate, and then drives the air inlet branch pipe 64 to rotate, the rotating sealing sleeve 66 can ensure the air tightness between the air inlet branch pipe 64 and the air pipe 67 when rotating.
[0054] See also Figure 1 , Figure 7 , Fig.11 and Fig.18 , the rotary drive assembly 72 includes a worm 721, a first gear 722, a motor 723, and a second gear 724. Since there are a plurality of air intake branch pipes 64 and worm wheels 65, the plurality of worm wheels 65 are meshed with the worm 721 for transmission. When the dredged sludge needs to be stirred, the motor 723 drives the second gear 724 to rotate, the second gear 724 drives the worm 721 to rotate, the worm 721 drives the plurality of worm wheels 65 to rotate, the worm wheel 65 drives the air intake branch pipe 64 to rotate, and then drives the first air blowing pipe 611 and the second air blowing pipe 621 to rotate. When the assembly plate 5 needs to be removed from the assembly port 11, the motor 723 drives the second gear 724 to rotate until the first air blowing pipe 611 and the second air blowing pipe 621 are coplanar, and the assembly plate 5 and the air supply assembly 6 can be pulled out through the control assembly 7.
[0055] See also Figure 1 , Figure 8 , Fig.12 and Fig.18 The water-dividing assembly 77 includes a plurality of water-dividing frames 771, a plurality of water-dividing blocks 772 and a plurality of drainage assemblies 773. When water slides down from the water-guiding slope 761, it will flow to the top of the water-dividing blocks 772 and the drainage assemblies 773. Since the width of the water-dividing frame 771 is the same as the width of the gap between the carrying box 71 and the assembly plate 5, the water will not flow onto the observation window 51, ensuring that the dehydration and fermentation of the dredged sludge can be clearly seen through the observation window 51. The plurality of water-dividing blocks 772 are respectively fixedly arranged on the top of the plurality of water-dividing frames 771, and the length of the water-dividing blocks 772 is the same as the length of the water-dividing frames 771. The cross-section of the water-dividing block 772 is an isosceles triangle, and the plurality of drainage assemblies 773 are respectively arranged above the plurality of air inlet branches 64, and the width of the drainage assemblies 773 is the same as the width between two adjacent water-dividing frames 771. The water flow can be guided to move to both sides to the drainage component 773, and the drainage component 773 can quickly discharge the accumulated water on the water diversion component 77 in the vertical direction.
[0056] See also Figure 8 and Figure 12-13The drainage assembly 773 includes a water flow guide plate 7731 and a plurality of plug pins 7732. The water flow guide plate 7731 is an inverted U-shaped structure. A plurality of drainage grooves 77311 are provided on the outer side walls on both sides of the water flow guide plate 7731. The end of the water dividing block 772 is directly opposite to the top opening of the drainage groove 77311, so the water flow left along the top inclined surface of the water dividing block 772 can directly enter the drainage groove 77311. The plurality of plug pins 7732 are respectively arranged in the plurality of drainage grooves 77311. Both ends of the plug pins 7732 are pointed ends and both extend out of the drainage groove 77311. The water entering the drainage groove 77311 can flow downward along the outer surface of the plug pin 7732. When the water flows to the bottom end of the plug pin 7732, it will drip downward. At this time, the water flow has left the drainage groove. Since the drainage groove is arranged on the outer surface of the water flow guide plate 7731 and the air intake branch pipe 64 is located on the inner side of the water flow guide plate 7731, the air intake branch pipe 64 will not contact the water flow during the drainage process of the drainage component 773.
[0057] See also Fig.13 , the opening area at the top of the drain groove 77311 is larger than the opening area at the bottom. When the drain groove 77311 is filled with water, the speed at which water flows out from the bottom of the drain groove 77311 can be increased. A water-collecting slope 77312 is provided on the outer wall of the water flow guide plate 7731 and below the drain groove 77311. The water-collecting slope 77312 is an inner concave surface. Part of the water in the drain groove 77311 drips through the bottom end of the pin 7732, and the other part of the water first flows onto the water-collecting slope 77312, and then drips from the bottom edge of the water-collecting slope 77312. Therefore, after the accumulated water on the water-dividing component 77 enters the drain groove 77311, it can be quickly discharged in the vertical direction in two ways.
[0058] In summary, the method of use of the present invention is as follows:
[0059] Step 1: Install the first geotube bag 2 and the second geotube bag 3 to the top and bottom of the assembly ring 1 respectively, and place the support plate 81 below the second geotube bag 3. Push the pull plate 73 to drive the carrying box 71 to move, and install the two assembly plates 5 in the two assembly ports 11 respectively, so that the first blowing assembly 61 and the second blowing assembly 62 extend into the accommodating cavity 4.
[0060] Step 2: Mix the dredged sludge with the porous biopolymer solution and the conditioning agent, and fill them into the containing cavity 4 through the first geotube bag 2.
[0061] Step three, place the pressure plate 83 above the second geotube bag 3, and connect the bottom of the strap 85 to the support plate 81. Under the pressure inside the two geotube bags, the pressure of the pressure plate 83 and gravity, the moisture in the dredged mud is discharged through the pores on the surface of the geotube bag. At the same time, under the action of the native microorganisms in the dredged mud, the soil enters a micro-fermentation state.
[0062] Step 4: 3-5 days after the geotube bag is filled, the dredged sludge officially enters the fermentation stage under the action of the composite bacterial agent inside the conditioner.
[0063] Step 5. During the fermentation process, the rotary drive assembly 72 regularly drives the first blowing assembly 61 and the second blowing assembly 62 to rotate. The first blowing assembly 61 and the second blowing assembly 62 regularly deliver air to the accommodating chamber 4 to promote aerobic fermentation of the dredged sludge. The moisture content of the sludge further decreases during the fermentation process.
[0064] Step 6: After the dredged mud is fermented into greening soil, the first blowing assembly 61 and the second blowing assembly 62 are driven to rotate by the rotating driving assembly 72, so that the first blowing assembly 61 and the second blowing assembly 62 are moved to the same plane, and then the pull plate 73 is dragged to drive the carrying box 71 to move. Pull out the two assembly plates 5 from the two assembly ports 11 respectively (see Fig.18 , the first geotube bag 2 and the support plate 81 are hidden in the figure, so that the first blowing assembly 61 and the second blowing assembly 62 leave the accommodating chamber 4, and the accommodating chamber 4 is connected to the outside through the assembly port 11.
[0065] Step 7: Apply downward pressure to the pressure plate 83, and collect the greening planting soil after it flows out from the assembly opening 11.
[0066] Step 8: first remove the pressure plate 83 and the support plate 81 , then remove the first geotube bag 2 and the second geotube bag 3 from the assembly ring 1 , and clean the assembly ring 1 , the first blowing assembly 61 and the second blowing assembly 62 .
