Description

Technical Field

[0001] This utility model relates to the field of bottom sediment dredging technology, and in particular to a bottom sediment dredging and dewatering treatment device. Background Technology

[0002] Sediment dredging is an engineering measure commonly used in water pollution control. Its main purpose is to reduce the endogenous pollution load by removing contaminated sediment. Sediment dredging can effectively improve water quality by removing nutrients (such as nitrogen and phosphorus), heavy metals and persistent organic pollutants from sediment, thereby reducing the risk of their re-release into the water.

[0003] After removing silt from riverbeds or lakebeds, it is necessary to separate the water from the silt. Geotextile bags are often used for water filtration. However, when geotextile bags are filled with water in the silt, they often use a static natural filtration method, which takes a long time to separate the water. Therefore, a bottom silt dredging and dewatering treatment device is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a bottom sediment dredging and dewatering treatment device to solve the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sediment dredging and dewatering treatment device includes a treatment frame, on which a bottom plate is mounted via a placement assembly. Multiple placement contact rollers are fixedly mounted on the top of the bottom plate, and geotextile tube bodies are placed on the multiple placement contact rollers. A rotating striking assembly is provided on the treatment frame, which is adapted to the bottom plate. An installation block is mounted on the top of the treatment frame via a lifting assembly, and a squeezing roller is mounted on the installation block via a reciprocating moving assembly. The squeezing roller is located above the geotextile tube body.

[0007] Preferably, the placement assembly includes multiple bottom support platforms fixedly installed at the bottom of the processing rack, a bottom plate placed on the bottom support platforms, and multiple guide columns fixedly installed at the bottom of the bottom plate, with the bottom ends of the multiple guide columns movably penetrating through the bottom of the processing rack.

[0008] Preferably, the bottom plate has multiple drainage holes at its bottom, and the side of the processing rack has multiple side holes.

[0009] Preferably, the rotating striking assembly includes a rotating motor fixedly installed on the side of the processing rack, the output end of the rotating motor is connected to a rotating shaft, and multiple striking wheels are fixedly installed on the rotating shaft, all of which are adapted to the bottom of the bottom plate.

[0010] Preferably, the striking wheel is elliptical in structure, and multiple striking wheels are arranged in a linear array.

[0011] Preferably, the lifting assembly includes a telescopic cylinder fixedly installed on the top of the processing rack, and the output end of the telescopic cylinder is fixedly connected to the top of the mounting block.

[0012] Preferably, the reciprocating moving component includes a rectangular groove formed at the bottom of the mounting block, a drive motor fixedly mounted on one side of the mounting block, a rotating lead screw connected to the output end of the drive motor, the rotating lead screw located in the rectangular groove, a lead screw slider threaded onto the rotating lead screw, a rotating frame fixedly mounted at the bottom of the lead screw slider, and a pressing roller rotatably mounted on the rotating frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The bottom sludge dredging and dewatering treatment device places the geotextile bag body on multiple contact rollers. The lifting component is set up so that during the natural gravity drainage process, the telescopic cylinder drives multiple squeezing rollers to move down, which can squeeze the geotextile bag body and quickly drain the water from the sludge inside the geotextile bag body. The back-and-forth moving component is set up so that the drive motor drives multiple squeezing rollers to move back and forth. While squeezing, they can also move back and forth, which can quickly and effectively squeeze and drain the geotextile bag body and accelerate the drainage effect of the internal sludge.

[0014] The rotating impact component, driven by a rotating motor, rotates the impact wheel, which continuously strikes the bottom plate. This impact generates vibrations that act on the geotextile bag body, dispersing the silt inside and accelerating the drainage of water. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Refer to Figures 1-4 A bottom sludge dredging and dewatering treatment device includes a treatment frame 1. A bottom plate 3 is installed on the treatment frame 1 via a placement component. Multiple placement contact rollers 19 are fixedly installed on the top of the bottom plate 3. Geotextile tube bodies 7 are placed on the multiple placement contact rollers 19. The dredged sludge is placed inside the geotextile tube body 7. After a certain amount is stored, the geotextile tube body 7 is sealed and then placed on the multiple placement contact rollers 19 on the treatment frame 1. The placement contact rollers 19 have a small contact area, allowing for rapid drainage at the bottom. A rotating striking component is provided on the treatment frame 1, which is adapted to the bottom plate 3. An installation block 9 is installed on the top of the treatment frame 1 via a lifting component. A squeezing roller 15 is installed on the installation block 9 via a reciprocating moving component. The squeezing roller 15 is located above the geotextile tube body 7.

[0022] Furthermore, the lifting assembly includes a telescopic cylinder 8 fixedly installed on the top of the processing frame 1. The output end of the telescopic cylinder 8 is fixedly connected to the top of the mounting block 9. During the natural gravity drainage process, the telescopic cylinder 8 at the top is activated, which drives the mounting block 9 to move down. After the mounting block 9 moves down, it drives multiple extrusion rollers 15 to move down. After the extrusion rollers 15 move down, they can extrude pressure on the geotextile bag body 7. After applying a certain pressure, the water in the silt inside the geotextile bag body 7 can be quickly discharged.

[0023] Furthermore, the reciprocating moving component includes a rectangular groove 10 formed at the bottom of the mounting block 9. A drive motor 11 is fixedly installed on one side of the mounting block 9. The output end of the drive motor 11 is connected to a rotating lead screw 12, which is located inside the rectangular groove 10. A lead screw slider 13 is threaded onto the rotating lead screw 12. A rotating frame 14 is fixedly installed at the bottom of the lead screw slider 13. The extrusion roller 15 is rotatably mounted on the rotating frame 14. After extrusion, the drive motor 11 is started to run. The drive motor 11 drives the rotating lead screw 12 to rotate. After the rotating lead screw 12 rotates, it drives the lead screw slider 13 to move. The lead screw slider 13 has a rectangular structure that matches the rectangular groove 10. The drive motor 11 is a forward and reverse motor. During rotation, it rotates forward at regular intervals and then reverses at regular intervals, which can synchronously drive multiple lead screw sliders 13 to move back and forth, thereby driving the extrusion roller 15 to move back and forth. It can move back and forth while extruding, which can quickly and effectively extrude and drain the geotextile bag body 7, and accelerate the drainage of internal silt.

[0024] Furthermore, the rotary impact assembly includes a rotary motor 16 fixedly installed on the side of the processing frame 1. The output end of the rotary motor 16 is connected to a rotary shaft 17, and multiple impact wheels 18 are fixedly installed on the rotary shaft 17. The multiple impact wheels 18 are adapted to the bottom of the bottom plate 3. The impact wheels 18 are elliptical in structure and arranged in a linear array. During the top extrusion process, the rotary motor 16 is started, driving the rotary shaft 17 to rotate, thereby driving the impact wheels 18 to rotate. After the impact wheels 18 rotate, they can continuously impact the bottom plate 3. After being impacted, the bottom plate 3 will move upward. The impact can generate vibration, which can act on the geotextile bag body 7, causing the silt inside to disperse and accelerating the drainage of water. During use, the striking wheel 18 can be equipped with a contact roller at its end, or a protective plate can be provided at the bottom of the bottom plate 3 to prevent damage to the bottom plate 3 caused by long-term vibration and striking. The placement assembly includes multiple bottom support platforms 6 fixedly installed at the bottom of the processing rack 1. The bottom plate 3 is placed on the bottom support platform 6. Multiple guide posts 5 are fixedly installed at the bottom of the bottom plate 3. The bottom ends of the multiple guide posts 5 all movably penetrate the bottom of the processing rack 1. The multiple guide posts 5 can limit the position of the bottom plate 3 during vibration and movement. The bottom support platform 6 can support the bottom position. Multiple drainage holes 4 are opened at the bottom of the bottom plate 3, and multiple side holes 2 are opened on the side of the processing rack 1.

[0025] In use: When removing silt from the bottom of lakes or rivers, the removed silt is placed inside the geotextile bag body 7. The geotextile bag body 7 is then placed on multiple placement contact rollers 19 on the processing frame 1. The telescopic cylinder 8 is activated, causing the mounting block 9 to move downwards, which in turn causes multiple compression rollers 15 to move downwards, squeezing the geotextile bag body 7. By applying a certain pressure, the water in the silt inside the geotextile bag body 7 can be quickly discharged. After squeezing, the drive motor 11 is activated, synchronously driving the multiple compression rollers 15 to move back and forth. While squeezing, it can also move back and forth, which can quickly and effectively squeeze and drain the geotextile bag body 7, accelerating the drainage of internal silt. During the squeezing process at the top, the rotating motor 16 is started to run, driving the rotating shaft 17 to rotate, which in turn drives the striking wheel 18 to rotate. After the striking wheel 18 rotates, it can continuously strike the bottom plate 3. After being struck, the bottom plate 3 will move upward. The vibration generated by the striking can act on the geotextile bag body 7, causing the internal silt to disperse and accelerating the drainage of water. It is convenient to use.
