Description

Technical Field

[0001] The present invention belongs to the technical field of sludge treatment, and specifically relates to a method and device for solidifying thick silt in a tidal estuary section. Background Technique

[0002] In the estuary of a river, due to the ebb and flow of the tide, a large amount of sediment is carried into the estuary. The sediment precipitates in places where the flow velocity is slower at the estuary, and it is easy to form a large amount of silt in the estuary section. When a large amount of silt is generated at the estuary, it is easy to affect the ecological environment at the estuary and the carrying capacity of the river channel.

[0003] When treating silt, the usual treatment method is to use chemical solidification treatment to treat the silt. Chemical solidification treatment refers to adding specific solidifying materials to the silt and mixing the solidifying agent with the silt by stirring, causing a series of physical and chemical reactions between the solidifying agent and the water in the silt, changing the mechanical properties of the silt, thereby improving the properties of high water content and low strength of the silt, and making the silt have the properties of high strength and low permeability.

[0004] In the process of mixing the silt with the solidifying agent, since the amount of silt taken at one time is not fixed, the amount of solidifying agent to be added to the silt is also not fixed. If the dosage of the solidifying agent added is too small, the solidification effect is likely to be poor. If the dosage of the solidifying agent added is too large, there will be a waste situation.

[0005] Therefore, the present invention provides a method and device for solidifying thick silt in a tidal estuary section. Summary of the Invention

[0037] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0038] As Figure 1 shown, a method for solidifying thick silt in a tidal estuary section according to an embodiment of the present invention, the specific steps of the solidifying method are as follows:

[0039] S1: Dig a mixing pit at the construction site. After the silt is pumped into the inside of the mixing pit by a screw pump, the silt is allowed to stand for a certain period of time to precipitate the solids in the silt, and then the supernatant is discharged.

[0040] S2: Place the solidifying device at the top of the mixing pit, and then add cement with the label P.O42.5R into the inside of the mixing pit.

[0041] S3: Add the diluted solidifying agent into the solidifying device, and add the solidifying agent into the inside of the mixing pit through the solidifying device. During the adding process, the solidifying device stirs and mixes the silt and cement inside the mixing pit.

[0042] S4: After the color of the silt turns bright black, continue to stir the silt for 10 - 15 minutes, and then pour the silt inside the mixing pit into the pre-prepared foundation trench and level the silt, then the solidification of the thick silt in the tidal estuary section can be completed.

[0043] As Figure 2 shown, the specific use steps of the solidifying device described in S2 are as follows:

[0044] S11: Place the storage box body 1 at the position corresponding to the top of the mixing pit, and push the support plate 10. After the height of the storage box body 1 is adjusted, rotate the stabilizing screw 12 to fix the support plate 10.

[0045] S12: After the storage box body 1 is set up, the silt will push the push bolt 13, causing the sliding frame 2 to move upward, and then the discharge pipe 5 to slide downward.

[0046] S13: Inject an appropriate amount of solidifying agent into the inside of the storage box body 1 through the injection port 101, so that the solidifying agent flows out through the discharge pipe 5 and flows into the inside of the mixing pit.

[0047] S14: Start the driving motor, so that the driving motor drives the stirring blade 8 to rotate through the rotating rod 7, and stir and mix the silt and the solidifying agent through the stirring blade 8. After the stirring and mixing are completed, the injection of the solidifying agent can be completed.

[0048] As Figures 3 to 5As shown in the figure, a thick silt solidification device for a tidal estuary section is provided. The thick silt solidification method for a tidal estuary section described in any of the above is used to solidify the silt with this solidification device, including a storage box body 1; a feeding port 101 is opened at the top of the storage box body 1; a sliding frame 2 is slidably connected inside the storage box body 1; a plurality of anti - detachment blocks 4 are fixedly connected to the side wall of the sliding frame 2; a push rod 401 is fixedly connected to the end of the anti - detachment block 4; a first sliding seat 402 is fixedly connected to the top of the storage box body 1; the push rod 401 is slidably connected inside the first sliding seat 402; a second sliding seat 404 is fixedly connected to the top of the storage box body 1; an air duct 403 is connected between the second sliding seat 404 and the first sliding seat 402; the air duct 403 is arranged at a position close to the top of the air duct 403; a discharge pipe 5 is slidably connected inside the second sliding seat 404; the discharge pipe 5 is slidably connected inside the storage box body 1; one end of the internal cavity of the discharge pipe 5 is arranged at a position corresponding to the inner side wall of the top of the storage box body 1; a blocking plate 6 is fixedly connected inside the storage box body 1 and is arranged at the end position corresponding to the internal cavity of the discharge pipe 5; both the sliding frame 2 and the discharge pipe 5 are arranged at positions corresponding to the bottom side wall of the storage box body 1; a plurality of floating balls 3 are fixedly connected to the bottom of the storage box body 1; a stirring component is arranged inside the sliding frame 2, and this stirring component can stir the silt and the curing agent inside the mixing pit; a supporting component is arranged at the bottom of the storage box body 1, and this supporting component can support the storage box body 1; during operation, when it is necessary to stir the silt inside the mixing pit, the storage box body 1 can be arranged at a position corresponding to the top of the mixing pit through the supporting component. After the storage box body 1 is arranged on the top of the silt, the buoyancy of the silt will push the sliding frame 2 to move upward. At the same time, floating balls 3 are arranged at the bottom of the sliding frame 2, which can increase the contact area between the sliding frame 2 and the silt, so that the buoyancy of the silt on the sliding frame 2 is greater. After the sliding frame 2 moves upward, the push rod 401 will move together with the sliding frame 2, so that the gas inside the first sliding seat 402 enters the inside of the second sliding seat 404 through the air duct 403, pushing the discharge pipe 5 to slide downward. Thus, during the process of the sliding frame 2 rising, the discharge pipe 5 will descend together, and then just the right amount of curing agent can be injected into the storage box body 1 to fill the storage box body 1 with an equal amount, so that the amount of the curing agent flowing out is the same as the amount to be used, making it more convenient to control the amount of the injected curing agent.

[0049] As Figures 3 to 4As shown, the stirring assembly includes a rotating rod 7; a driving motor is installed inside the sliding frame 2; the output end of the driving motor is fixedly connected to the rotating rod 7; a plurality of stirring blades 8 are fixedly connected to the side wall of the rotating rod 7; the stirring blades 8 are arranged regularly in a circumferential array on the side wall of the rotating rod 7; during operation, after placing the storage box 1 on the top of the mixing pit, the driving motor can be started, so that the driving motor drives the stirring blades 8 to rotate through the rotating rod 7, so that during the addition of the curing agent, the sludge and the curing agent can be stirred, so that the curing agent can better penetrate into the sludge, so that the mixing effect of the sludge and the curing agent is better, and the treatment effect of the sludge is better.

[0050] As Figure 3 , Figure 6 and Figure 7 shown, the support assembly includes support feet 9; the support feet 9 are rotatably connected inside the storage box 1; the support feet 9 are arranged near the bottom surface of the storage box 1, and there are multiple support feet 9 at the bottom of the storage box 1; the end of the support feet 9 away from the storage box 1 is rotatably connected to a support plate 10; a contact groove 11 is opened on the side wall of the support plate 10; a stabilizing screw 12 is threadedly connected inside the support plate 10; a pushing bolt 13 is threadedly connected to the side wall of the storage box 1; a sliding block 14 is slidably connected inside the storage box 1; the pushing bolt 13 is rotatably connected inside the sliding block 14; the sliding block 14 is arranged at the rotating shaft of the corresponding support foot 9; during operation, when it is necessary to place the storage box 1 on the top of the mixing pit, first, the pushing bolt 13 can be rotated so that the pushing bolt 13 disengages from the rotating shaft of the support foot 9, so that the support foot 9 can deflect. After the angle of the support foot 9 is adjusted, the stabilizing screw 12 can be rotated and screwed into the soil to fix the support plate 10. After the support plate 10 is adjusted, the pushing bolt 13 can be rotated so that the pushing bolt 13 pushes the sliding block 14, so that the sliding block 14 and the rotating shaft of the support foot 9 are mutually pressed to fix the support foot 9, so that the support foot 9 and the support plate 10 are more stable during the process of supporting the storage box 1. At the same time, a contact groove 11 is opened on the side wall of the support plate 10, which can make the contact area between the support plate 10 and the surrounding soil larger, so that the support of the support plate 10 is more stable.

[0051] As Figure 7 shown, a plurality of anti-slip teeth 15 are fixedly connected to the side wall of the sliding block 14; a plurality of anti-slip grooves 16 are opened at the rotating shaft of the support foot 9; the anti-slip teeth 15 and the anti-slip grooves 16 are arranged in correspondence; during operation, when the sliding block 14 and the rotating shaft of the support foot 9 are mutually pressed, through the meshing of the anti-slip teeth 15 and the anti-slip grooves 16, the friction between the sliding block 14 and the rotating shaft of the support foot 9 can be made larger, so that the fixing effect of the sliding block 14 on the support foot 9 is better.

[0052] As Figure 7 shown, a plurality of ball bearings 17 are provided between the push bolt 13 and the sliding block 14; the side walls of the ball bearings 17 are in contact with the side walls of the push bolt 13 and the sliding block 14; during operation, when the push bolt 13 rotates inside the sliding block 14, the rolling of the ball bearings 17 can make the friction between the push bolt 13 and the sliding block 14 smaller, reduce the wear between the push bolt 13 and the sliding block 14, and increase the service life of the device.

[0053] As Figure 4 shown, a wire holder 18 is fixedly connected to the top of the sliding frame 2; the wire holder 18 is slidably connected inside the storage box 1; the wire holder 18 is arranged at the position corresponding to the top side wall of the storage box 1; during operation, when a drive motor is installed inside the sliding frame 2, the power cord of the drive motor can be led out through the wire holder 18, thereby effectively avoiding the situation that liquid enters the inside of the drive motor and affects the operation of the drive motor.

[0054] As Figure 4 shown, a positioning rod 19 is fixedly connected inside the storage box 1; the positioning rod 19 is arranged at the position corresponding to the anti - detachment block 4; the anti - detachment block 4 is slidably connected to the outer side wall of the positioning rod 19; during operation, when the sliding frame 2 slides up and down, through the restriction of the positioning rod 19 on the anti - detachment block 4, the sliding frame 2 can be less skewed during sliding, so that the sliding of the sliding frame 2 is more stable.

[0055] As Figure 5 shown, a sealing gasket 20 is fixedly connected inside the storage box 1; the sealing gasket 20 is arranged at the position corresponding to the discharge pipe 5; during operation, by arranging the sealing gasket 20 at the position corresponding to the discharge pipe 5, the sealing performance between the storage box 1 and the discharge pipe 5 can be better, thereby effectively avoiding the situation that liquid leaks out through the gap between the discharge pipe 5 and the storage box 1.

[0056] During operation, when the sludge inside the mixing pit needs to be stirred, the storage box 1 can be set at a position corresponding to the top of the mixing pit through the supporting assembly. After the storage box 1 is set on the top of the sludge, the buoyancy of the sludge will push the sliding frame 2 to move upward. At the same time, a float 3 is set at the bottom of the sliding frame 2 to increase the contact area between the sliding frame 2 and the sludge, so that the buoyancy of the sludge on the sliding frame 2 can be greater. After the sliding frame 2 moves upward, the push rod 401 will move with the sliding frame 2, so that the gas inside the first sliding seat 402 enters the second sliding seat 404 through the air guide pipe 403, pushing the discharge pipe 5 to slide downward, so that the discharge pipe 5 will descend together during the rising process of the sliding frame 2, and then the same amount of curing agent can be injected into the storage box 1 to fill the storage box 1, so that the amount of curing agent flowing out is the same as the amount required, which makes it more convenient to control the amount of curing agent injected.

[0057] After the storage box 1 is placed on the top of the mixing pit, the drive motor can be started so that the drive motor drives the stirring blade 8 to rotate through the rotating rod 7, so that the sludge and the curing agent can be stirred during the process of adding the curing agent, so that the curing agent can be better integrated into the interior of the sludge, thereby achieving a better fusion effect of the sludge and the curing agent, and achieving a better treatment effect on the sludge.

[0058] When it is necessary to set the storage box 1 on the top of the mixing pit, the pushing bolt 13 can be rotated first, so that the pushing bolt 13 is disengaged from the rotating shaft of the supporting foot 9, so that the supporting foot 9 can be deflected. When the angle of the supporting foot 9 is adjusted, the stabilizing screw 12 can be rotated, and the stabilizing screw 12 can be screwed into the soil to fix the supporting plate 10. When the adjustment of the supporting plate 10 is completed, the pushing bolt 13 can be rotated so that the pushing bolt 13 pushes the sliding block 14, so that the sliding block 14 and the rotating shaft of the supporting foot 9 are squeezed against each other to fix the supporting foot 9, so that the supporting foot 9 and the supporting plate 10 are more stable in the process of supporting the storage box 1. At the same time, a contact groove 11 is opened on the side wall of the supporting plate 10, so that the contact area between the supporting plate 10 and the surrounding soil can be larger, thereby making the support of the supporting plate 10 more stable.

[0059] When the sliding block 14 and the rotating shaft of the supporting foot 9 are pressed against each other, the anti-skid teeth 15 and the anti-skid grooves 16 engage with each other, so that the friction between the sliding block 14 and the rotating shaft of the supporting foot 9 is greater, so that the sliding block 14 has a better fixing effect on the supporting foot 9.

[0060] When the push bolt 13 rotates inside the sliding block 14, the rolling of the ball 17 can reduce the friction between the push bolt 13 and the sliding block 14, thereby reducing the wear between the push bolt 13 and the sliding block 14 and increasing the service life of the device.

[0061] After installing the driving motor inside the carriage 2, the power cord of the driving motor can be led out through the wire holder 18, thus effectively avoiding the situation where liquid enters the inside of the driving motor and affects the operation of the driving motor.

[0062] When the carriage 2 slides up and down, through the restriction of the anti - detachment block 4 by the positioning rod 19, the carriage 2 can be less skewed during the sliding process, so that the sliding of the carriage 2 is more stable.

[0063] By setting a gasket 20 at the position corresponding to the discharge pipe 5, the sealing performance between the storage box 1 and the discharge pipe 5 can be better, thus effectively avoiding the situation where liquid leaks out through the gap between the discharge pipe 5 and the storage box 1.
