Description

Technical Field

[0001] This utility model relates to the technical field of silt removal, specifically to a silt removal device for river ecological environment. Background Technology

[0002] Silt deposition in river channels raises the riverbed and reduces the cross-sectional area of ​​water flow, leading to a decrease in the river's flood storage and discharge capacity. During heavy rains, water flow is obstructed, water levels rise rapidly, and the risk of levee breaches or overflows increases. Siltation in lakes reduces reservoir capacity, weakening their ability to regulate flood peaks. Silt is rich in organic matter, and excessive accumulation can lead to eutrophication and blackening of water bodies, such as the outbreak of blue-green algae. Thick layers of silt covering riverbeds / lake bottoms destroy the habitat of aquatic plants and benthic organisms (such as snails and clams).

[0003] Currently, silt removal requires river closure, primarily for small rivers, or draining lakes. Silt is then pumped to a screw extrusion dewatering machine for dewatering. If the silt is compacted, manual flushing with water is necessary. The pump is then positioned to allow water to carry the silt to the pump. However, due to the large scale of silt removal projects, the screw extrusion dewatering machine requires continuous high-frequency operation, placing a heavy burden on it. Increasing the rotational speed of the screw in the dewatering machine also reduces the dewatering effect. Therefore, a river ecological environment silt removal device needs to be designed. Utility Model Content

[0004] In view of the above-mentioned technical problems, the purpose of this utility model is to overcome the problem that increasing the operating speed of the spiral extrusion dewatering machine during the dredging process will reduce the dewatering effect.

[0005] To achieve the above objectives, this utility model provides a river ecological environment silt cleaning device, including a screw extrusion dewatering machine and a dredging pump, and further including: a first mounting frame mounted on the screw extrusion dewatering machine, a vertical cylindrical frame mounted on the first mounting frame, a feed pipe mounted on the bottom of the cylindrical frame and connected to the feed end of the screw extrusion dewatering machine, and a geotextile dewatering bag with its open end mounted on the top of the cylindrical frame by an installation mechanism. The bottom of the geotextile dewatering bag is provided with a discharge port connected to the upper end of the feed pipe. The first mounting frame is also equipped with an auxiliary dewatering unit for continuously tapping the outer wall of the geotextile dewatering bag.

[0006] Preferably, the first mounting frame includes a horizontal first ring piece arranged coaxially with the cylindrical frame, and the auxiliary dehydration unit includes an annular slide fixedly mounted on the first ring piece, a plurality of striking arms spaced along the circumferential direction of the annular slide and rotatably mounted on the first ring piece through hinge seats, an annular rack slidably mounted on the annular slide, and a drive mechanism for driving the annular rack to rotate. Each of the striking arms is provided with an elastic mechanism connected to the first ring piece for pushing the striking arm closer to the cylindrical frame to rotate and strike the soil dewatering bag; the hinge seat is located inside the first ring piece. The striking arm is fitted with a pulley on the side of the striking arm away from the cylindrical frame via a mounting bracket. The annular rack is fitted with at least one vertical push plate that matches the pulley. The push plate is located on one side of the annular rack in the direction of rotation and is inclined close to the cylindrical frame to form an inclined section.

[0007] Preferably, the elastic mechanism includes an arc-shaped rod that is mounted on the striking arm via a mounting member and is coaxial with the rotation axis of the hinge seat, a mounting seat located outside the annular rack and fixedly mounted on the first ring piece, and a spring sleeved on the arc-shaped rod; The end of the arc-shaped rod away from the mounting component slides through the mounting base, and a limit ring is fixedly fitted to the end of the arc-shaped rod away from the mounting component. The two ends of the spring abut against the mounting component and the mounting base, respectively.

[0008] Preferably, the drive mechanism includes a motor mounted on a screw extrusion dewatering machine via a second mounting bracket and a gear fixedly mounted on the output shaft of the motor and meshing with a ring rack.

[0013] According to the above technical solution, the river ecological environment silt removal device provided by this utility model has the following beneficial effects when in use: The dredging pump pumps the sludge into the geotextile dewatering bag, where it undergoes initial dewatering. The sludge will block the holes in the geotextile dewatering bag, so with the continuous tapping of the auxiliary dewatering unit, the sludge adhering to the inner wall of the geotextile dewatering bag can be temporarily separated, increasing the amount of water removed and improving the dewatering effect of the geotextile dewatering bag.

[0017] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0018] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0019] like Figure 1-6 As shown, a river ecological environment silt cleaning device includes a screw extrusion dewatering machine 1 and a dredging pump, and further includes: a first mounting frame 2 mounted on the screw extrusion dewatering machine 1, a vertical cylindrical frame 3 mounted on the first mounting frame 2, a feed pipe 4 mounted on the bottom of the cylindrical frame 3 and connected to the feed end of the screw extrusion dewatering machine 1, and a geotextile dewatering bag 5 whose open end is mounted on the top of the cylindrical frame 3 by an installation mechanism. The bottom of the geotextile dewatering bag 5 is provided with a discharge port connected to the upper end of the feed pipe 4. The first mounting frame 2 is also equipped with an auxiliary dewatering unit for continuously tapping the outer wall of the geotextile dewatering bag 5.

[0020] In the above technical solution, both the screw extrusion dewatering machine 1 and the dredging pump are existing mature technologies. Therefore, the dredging pump is not shown in the figure, and the structure and principle of the two will not be described in this article. The dredging pump is used to pump out the silt from the river or lake, and the screw extrusion dewatering machine 1 can dewater the silt. The dredging pump pumps the sludge into the geotextile dewatering bag 5, where it undergoes initial dewatering. Some water flows out through the geotextile dewatering bag 5, while the sludge blocks the holes. Therefore, with the continuous tapping of the auxiliary dewatering unit, the sludge adhering to the inner wall of the geotextile dewatering bag 5 can be temporarily separated, increasing the dewatering capacity and improving the dewatering effect of the geotextile dewatering bag 5. Dewatering through the geotextile dewatering bag 5 not only reduces the workload of the screw extrusion dewatering machine 1, but also helps to reduce the moisture content of the produced sludge residue. After initial dewatering, the sludge enters the screw extrusion dewatering machine 1 through the discharge port, where it undergoes further dewatering to produce sludge with low water content. In a preferred embodiment of the present invention, the first mounting frame 2 includes a horizontal first annular piece 6 coaxially arranged with the cylindrical frame 3, and the auxiliary dehydration unit includes an annular slide 7 coaxially fixedly mounted on the first annular piece 6, a plurality of striking arms 9 spaced along the circumferential direction of the annular slide 7 and rotatably mounted on the first annular piece 6 via hinge seats 8, an annular rack 10 slidably mounted on the annular slide 7 coaxially, and a driving mechanism for driving the annular rack 10 to rotate. Each of the striking arms 9 is provided with an elastic mechanism connected to the first ring piece 6 for pushing the striking arm 9 close to the cylindrical frame 3 to rotate and strike the soil-supporting dewatering bag 5. The hinge seat 8 is located inside the first ring piece 6. The striking arm 9 is equipped with a pulley 11 on the side of the striking arm 9 away from the cylindrical frame 3 via a mounting bracket. The annular rack 10 is equipped with at least one vertical push plate 12 that matches the pulley 11. The push plate 12 is located on the side of the annular rack 10 in the direction of rotation and is inclined close to the cylindrical frame 3 to form an inclined portion 13.

[0021] In the above technical solution, a housing can be fitted on the outside of the auxiliary unit, wherein the striking arm 9 passes through the housing outward, and the striking arm 9 and the housing can be sealed by a corrugated rubber sleeve. The drive mechanism drives the ring rack 10 to rotate, and the ring rack 10 drives the push plate 12 to slide along the circumference of the cylindrical frame 3. When the inclined part 13 contacts the pulley 11, it will drive the striking arm 9 to rotate around the hinge seat 8 away from the cylindrical frame 3 through the pulley 11. When the push plate 12 passes the pulley 11, the pulley 11 instantly loses the support of the push plate 12, and the elastic mechanism will push the striking arm 9 to strike the outer wall of the geotextile dewatering bag 5, thereby causing the silt adhering to the holes of the geotextile dewatering bag 5 to be separated instantly through vibration.

[0022] In a preferred embodiment of the present invention, the elastic mechanism includes an arc-shaped rod 15 mounted on the striking arm 9 via a mounting member 14 and arranged coaxially with the rotation axis of the hinge seat 8, a mounting seat 16 located outside the annular rack 10 and fixedly mounted on the first ring piece 6, and a spring 17 sleeved on the arc-shaped rod 15. The end of the arc-shaped rod 15 away from the mounting member 14 slides through the mounting base 16, and the end of the arc-shaped rod 15 away from the mounting member 14 is fixedly fitted with a limit ring 18. The two ends of the spring 17 abut against the mounting member 14 and the mounting base 16 respectively.

[0023] In the above technical solution, when the contact pulley 11 continues to rotate after being pushed, the striking arm 9 rotates away from the cylindrical frame 3, causing the arc rod 15 to rotate, the distance between the mounting part 14 and the mounting base 16 decreases, and the spring 17 is further compressed; after the push plate 12 separates from the pulley 11, the elastic potential energy of the spring 17 will be converted into the kinetic energy of the striking arm 9, so that the striking arm 9 strikes the outer wall of the geotextile dewatering bag 5.

[0024] In a preferred embodiment of the present invention, the driving mechanism includes a motor 19 mounted on a screw extrusion dewatering machine 1 via a second mounting bracket and a gear fixedly mounted on the output shaft of the motor 19 and meshing with an annular rack 10.

[0025] In the above technical solution, the motor 19 drives the gear to rotate, thereby causing the ring rack 10 to slide on the ring slide block 7.

[0026] In a preferred embodiment of the present invention, the installation mechanism includes a first mounting ring 20 coaxially arranged with the cylindrical frame 3 and capable of pressing against the open end of the geotextile dewatering bag 5, and a plurality of first mounting bolts passing through the first mounting ring 20 and the top of the cylindrical frame 3.

[0027] In the above technical solution, when it is necessary to replace the geotextile dewatering bag 5, several first mounting bolts are loosened and removed, and the mounting ring is removed, so that the open end of the geotextile dewatering bag 5 is separated from the top of the cylindrical frame 3.

[0028] In a preferred embodiment of this utility model, the lower part of the cylindrical frame 3 is conical.

[0029] In the above technical solution, the conical lower part of the cylindrical frame 3 facilitates the entry of the silt carried by the soil dewatering process into the feed pipe 4 of the screw extrusion dewatering machine 1.

[0030] In a preferred embodiment of the present invention, a second ring piece 21 is coaxially arranged at the bottom of the cylindrical frame 3, the upper end of the feed pipe 4 is fixedly connected to the second ring piece 21, and a second mounting ring piece assembled on the second ring piece 21 by a plurality of second mounting bolts is pressed on the discharge port.

[0031] In the above technical solution, after the open end of the geotextile dewatering bag 5 is separated from the cylindrical frame 3, several second mounting bolts are loosened and removed, and the second mounting ring is taken off, so that the old geotextile dewatering bag 5 can be replaced. The operation is simple and convenient.

[0032] In a preferred embodiment of this utility model, the end of the striking arm 9 away from the hinge seat 8 is bent away from the cylindrical frame 3 to form an arc-shaped portion 22.

[0033] In the above technical solution, the arc-shaped part 22 can prevent the end of the striking arm 9 from scratching the outer wall of the geotextile dewatering bag 5.

[0034] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0035] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0036] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
