Technical Field
[0001] This invention relates to the field of silt solidification technology, specifically a process for solidifying river silt. Background Technology
[0002] River dredging technologies mainly include the following: 1. Drainage dredging: This method involves constructing temporary cofferdams in the river construction section to drain the river water and then dry-dredging or hydraulic dredging; 2. Underwater dredging: This generally refers to equipping dredging equipment on a boat, using the dredging vessel as a construction platform to operate the dredging equipment on the water surface to excavate silt, and then transporting it to the shore storage area through a pipeline system.
[0003] The river silt solidification process described in patent number CN110482915A is subject to site limitations during use, cannot be applied to various environments, and cannot be quickly assembled and processed in various locations. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a river silt solidification process that solves the aforementioned problems.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a river silt solidification process comprising the following steps:
[0006] Step 1: Construct a cofferdam in the river channel and use a pump to drain the river water inside the cofferdam to the outside of the cofferdam.
[0007] Step 2: Depth measurement of the silt in the river section to be solidified is performed to obtain the silt depth of the river section, and silt samples are taken from the river section to obtain silt samples. The silt samples are tested and analyzed to obtain the composition and water content of the silt in the river section.
[0008] Step 3: Based on the composition of the sludge obtained in Step 2, select the type of solidifying agent;
[0009] Step 4: Extract the silt from the cofferdam and filter it using a filtration device. Then, assemble the solidification mechanism of the solidification equipment. Calculate the area based on the site area and assemble the horizontal and vertical plates to form a silt solidification tank. Then, assemble the connecting rods and attach the feeding auger above the silt solidification tank. Finally, put the solidifying agent into the solidifying agent storage box and extract the silt using the feeding auger.
[0010] Step 5: The sludge is conveyed by a feeding auger. During conveying, the curing agent in the curing agent storage tank is sprayed out from the discharge port and sprayed onto the surface of the sludge for mixing. Then the sludge accumulates in the sludge curing tank. Then, the external power mechanism drives the rotating disc to rotate, which drives the transmission rope to rotate, which drives the transmission block to move left and right, and drives the scraper to sweep the accumulated sludge flat and spread it out. During the movement, the support frame moves on the horizontal plate for auxiliary positioning, and the guide wheel rotates on the horizontal plate for guidance.
[0011] Step Six: After the sludge solidifies, solidified soil is produced. At this time, the horizontal plate on one side of the sludge solidification tank is removed, and then the solidified soil is dug out and transported to the designated location. After cleaning, the horizontal plate is reassembled.
[0012] As a further aspect of the present invention: when assembling the curing mechanism of the curing equipment in step four, the horizontal and vertical plates are assembled according to the site area to form a sludge curing tank. Then the connecting rods are assembled, the feeding auger is assembled above the sludge curing tank, and the curing agent is placed in the curing agent storage box.
[0013] As a further aspect of the present invention: during the mixing of the curing agent in step five, the curing agent in the curing agent storage box is sprayed out from the discharge port and sprayed onto the surface of the sludge for mixing.
[0014] As a further aspect of the present invention: in step five, when spreading the silt, an external power mechanism drives the rotating disk to rotate, which in turn drives the transmission rope to rotate, which in turn drives the transmission block to move left and right, and drives the scraper to sweep the accumulated silt flat and spread it.
[0015] As a further aspect of the present invention: during the auxiliary positioning in step five, the support frame moves on the horizontal plate, and the guide wheel rotates on the horizontal plate for guidance.
[0016] As a further aspect of the present invention: in step six, when cleaning the solidified soil, one side of the horizontal plate of the silt solidification tank is removed, and then the solidified soil is dug out and transported to the designated location. After cleaning, the horizontal plate is reassembled.

The outlet of the feeding auger is located directly above the solidification mechanism. The sludge is transported to a fixed mechanism for accumulation through the bottom of the feeding auger. A solidifying agent storage tank is fixedly connected to the top of the feeding auger. The solidifying agent storage tank has a discharge port located above the outlet of the feeding auger. When the sludge is output from the feeding auger, the solidifying agent in the storage tank is sprayed out from the discharge port, spraying onto the surface of the sludge for better mixing and ensuring that most of the sludge comes into contact with the solidifying agent. The solidification mechanism includes interlocking horizontal and vertical plates. Both the horizontal and vertical plates are composed of multiple sections of sheet metal connected by interlocking blocks. They can be freely assembled according to usage requirements to adjust different widths and lengths to suit various environments. The operation is simple and convenient. It can shield the sides of the sludge for accumulation. The lengths of the sheet metal components of the horizontal and vertical plates are not fixed, and various sizes can be used together. The top of the horizontal plate is fixedly connected to... A support plate has a rotating disk rotatably connected to its inner cavity. A transmission rope is driven to the surface of the rotating disk, and a transmission block is fixedly connected to the surface of the transmission rope. A connecting rod is threadedly connected to the side of the transmission block. The connecting rod is assembled from multiple threaded rods, and a scraper rod and a support rod are respectively fitted onto the surface of the connecting rod. A support frame is fixedly connected to the bottom of the support rod, and the bottom of the support frame is slidably connected to the top of the horizontal plate. A guide wheel is rotatably provided in the inner cavity of the horizontal plate, abutting against the surface of the horizontal plate. In use, the rotating disk is driven to rotate by an external power mechanism, which drives the transmission rope to rotate and drives the transmission block to move left and right. This can drive the scraper rod to sweep and flatten the accumulated sludge. The support rod supports the connecting rod. During movement, the support frame moves on the horizontal plate for auxiliary positioning. The threaded rod segments of the connecting rod are the same size as the multiple plate segments of the vertical plate, and the length of the connecting rod can be easily adjusted according to the usage requirements. It is easy to assemble, simple to operate, and can quickly load and flatten materials.
