Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, and more specifically to a river sludge treatment device. Background Art

[0002] River and lake silt is typically a mixture of clay, sediment, organic matter, and various minerals. It settles to the bottom of rivers and lakes through long-term physical, chemical, and biological processes, as well as water transport. Deposited in still or slowly flowing water, river and lake silt forms unconsolidated, soft, fine-grained or ultrafine-grained soil through physical, chemical, and biochemical processes. Due to its high water content and contaminants such as heavy metals and organic matter, arbitrarily depositing it generates odors and inevitably causes secondary pollution to the surrounding environment. It is a modern, recent sediment. River silt treatment is a crucial step in urban water environment management.

[0003] For example, the utility model with publication number CN220432592U discloses a river sludge treatment device. The first step is to place a sludge delivery pipe in the river, open a sludge pump, and extract the sludge in the river through the sludge delivery pipe and transfer it to a sludge tank through the sludge delivery pipe.

[0004] Step 2: When the sludge in the sludge box reaches a certain amount, the sludge pump is turned off, the baffle is located above the hand screw, the hand screw is retracted, and the baffle moves downward under the influence of gravity, thereby driving the movable plate to rotate along the limit column, and a water outlet is opened at the bottom of the sludge box. The sludge is located above the filter screen, and the water in the sludge passes through the filter screen and flows out from the water outlet. After filtering for a period of time, the hand screw is tightened to drive the baffle to move upward, thereby restoring the movable plate to a level with the sludge box;

[0005] Step 3: Turn on the curing light strip to heat the silt in the sludge box, open the electric butterfly valve, and add the curing agent into the silt to solidify the silt in the sludge box. After the curing is completed, push the transport cart into the bracket and locate it under the silt box. Turn on the electric push rod and push the movable plate to slide along the silt box to open the bottom of the silt box. The solidified silt falls from the silt box into the transport cart due to gravity.

[0006] Regarding the above solution: The inventor believes that the above reference document completes the dehydration process by placing the sludge on a filter net so that the water in the sludge flows out through the filter net.

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts are within the scope of protection of the present invention.

[0027] Example:

[0028] A river silt treatment device includes a treatment box 1, a filter plate 2 is fixedly connected to the inside of the treatment box 1, and an extrusion mechanism is provided on one side of the filter plate 2. The filter plate 2 can be placed inside the treatment box 1, and the silt can be placed on the upper side of the filter plate 2. The moisture in the silt will fall through the holes of the filter plate 2 to achieve dehydration of the silt, and the moisture will fall to the bottom of the treatment box 1.

[0029] The squeezing mechanism includes a first hollow groove 31 opened inside the processing box 1. The processing box 1 is located inside the first hollow groove 31 and is rotatably connected to a threaded rod 32. The outer side of the threaded rod 32 is threadedly connected to a first connecting block 33 and a second connecting block 34. The first connecting block 33 and the second connecting block 34 are both slidably connected to the inside of the first hollow groove 31. A first squeezing plate 35 is fixedly connected to one side of the second connecting block 34. A second squeezing plate 36 is fixedly connected to one side of the second connecting block 34. The first squeezing plate 35 and the second squeezing plate 36 are both located on the upper side of the filter plate 2.

[0030] A threaded rod 32 can be installed inside the first hollow groove 31, and the threads on both sides of the threaded rod 32 are opposite, so that when the threaded rod 32 rotates, it can drive the first connecting block 33 and the second connecting block 34 to move in the opposite direction. The first squeezing plate 35 and the second squeezing plate 36 can move on the upper side of the filter plate 2, and can also be driven by the first connecting block 33 and the second connecting block 34 to move in the opposite direction. This allows the first squeezing plate 35 and the second squeezing plate 36 moving in the opposite direction to squeeze the silt on the upper side of the filter plate 2, which can make the silt dehydration faster and more thorough. At the same time, because the silt is squeezed from both sides, it is not easy for the silt to clog the holes of the filter plate 2 when squeezed.

[0031] See also Figure 2 A cylinder 41 is fixedly connected to one side of the processing box 1, and the top rod of the cylinder 41 passes through one side of the processing box 1.

[0032] A push plate 43 can be placed inside the second hollow groove 42, so that the push plate 43 is not likely to hinder the movement of the first extrusion plate 35 and the second extrusion plate 36, and the cylinder 41 can drive the push plate 43 to move. The moving push plate 43 can push the silt on the upper side of the filter plate 2, so that the silt can move out of the upper side of the filter plate 2 and move out through the third hollow groove 44. The baffle 45 can be used to block the third hollow groove 44, so that the silt is not easy to fall out during dehydration.

[0033] See also Figure 2 A thread groove 51 is provided on one side of the treatment box 1. The internal thread of the treatment box 1 in the thread groove 51 is connected to a thread block 52. A handle 53 is fixedly connected to one side of the thread block 52. The thread groove 51 allows the moisture separated from the sludge inside the treatment box 1 to be discharged through the thread groove 51, while the thread block 52 can block the thread groove 51 and detach from the thread groove 51 by rotation. The handle 53 makes it easy for people to rotate the thread block 52.

[0034] See also Figure 2 A guide plate 6 is provided on one side of the threaded block 52, and the guide plate 6 is fixedly connected to the processing box 1. The shape of the guide plate 6 is triangular. The guide plate 6 can guide the moisture at the bottom inside the processing box 1 so that the moisture can be discharged smoothly through the threaded groove 51 and is not easily accumulated inside the processing box 1.

[0035] See also Figure 1-2 The upper side of the treatment box 1 is hinged with a cover plate 71 through a hinge. The upper side of the cover plate 71 is fixedly connected to a sludge pump 72. One side of the sludge pump 72 is fixedly connected to a first pipe 73, and one side of the first pipe 73 passes through the cover plate 71. The other side of the sludge pump 72 is fixedly connected to a second pipe 74. The cover plate 71 can block the upper side of the treatment box 1, making it difficult for foreign matter to enter the interior of the treatment box 1, while the sludge pump 72 can extract sludge through the second pipe 74 and discharge it to the upper side of the filter plate 2 through the first pipe 73, which makes the extraction of sludge more convenient.

[0036] See also Figure 2 A support plate 81 is fixedly connected to one side of the processing box 1, and a collecting box 82 is provided on the upper side of the support plate 81. The collecting box 82 can be placed on the upper side of the support plate 81, and the collecting box 82 is located on one side of the third hollow groove 44, which can receive the sludge pushed out by the pushing plate 43, so as to facilitate the collection and treatment of the sludge, and a curing agent can also be poured into the inside of the collecting box 82 to make the sludge solidify more quickly.

[0037] See also Figure 3A motor 9 is fixedly connected to one side of the processing box 1, and the output shaft of the motor 9 passes through the processing box 1. The output shaft of the motor 9 is fixedly connected to the threaded rod 32 through a coupling. The motor 9 can be used to drive the threaded rod 32 to rotate, making the rotation of the threaded rod 32 more convenient, and people do not need to manually rotate the threaded rod 32.

[0038] The working principle and use process of the present invention are as follows: when using the device, first start the sludge pump 72 to extract the sludge through the second pipe 74 and discharge it to the upper side of the filter plate 2 through the first pipe 73, then start the motor 9 to drive the threaded rod 32 to rotate. The threaded rod 32 will drive the first connecting block 33 and the second connecting block 34 to move in the opposite direction due to the opposite threads on both sides. At the same time, the first connecting block 33 and the second connecting block 34 will respectively drive the first squeezing plate 35 and the second squeezing plate 36 to move in the opposite direction, thereby squeezing the sludge on the upper side of the filter plate 2. The squeezed sludge is The internal moisture will fall and be absorbed through the holes of the filter plate 2, which can make the sludge dehydrated faster and more thoroughly. Then the cylinder 41 is started to drive the push plate 43 to move. The push plate 43 will push the dehydrated sludge out of the upper side of the filter plate 2 and fall into the interior of the collection box 82. A curing agent can be poured to solidify the sludge. Finally, the threaded block 52 is rotated to disengage the threaded groove 51 to discharge the moisture at the bottom of the treatment box 1. At this point, the problem of simply placing the sludge on the filter net and lacking external force to squeeze the sludge, resulting in slow dehydration and incomplete dehydration, can be solved.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and improved ideas of the present invention, which should be covered by the protection scope of the present invention.
