Description

Technical Field

[0001] This utility model belongs to the field of environmental engineering technology, specifically relating to in-situ solidification and remediation equipment for pollutants in riverbed sediment. Background Technology

[0002] In-situ solidification and remediation of pollutants in riverbed sediment is a common water body ecological treatment technology, widely used in the control of sediment pollution in urban black and odorous water bodies, lakes and rivers. This technology mainly involves adding solidifying agents to the sediment and using a mixing device to fully mix them with the sediment in order to reduce the activity of pollutants and improve the physicochemical properties of the sediment. However, traditional remediation methods often involve excavating the sediment with excavators and then treating it on-site, which has problems such as high construction costs, high risk of secondary pollution, and serious ecological disturbance.

[0003] In existing technologies, traditional riverbed sediment pollutant treatment equipment typically uses a unidirectional stirring method to process the sludge, which makes it difficult to achieve all-round, multi-angle crushing and uniform mixing of the sediment. This can easily lead to uneven distribution of the solidifying agent, reduce treatment efficiency, and affect the overall remediation effect. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0016] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0017] Reference Figures 1-4 This embodiment of the present invention provides an in-situ solidification and remediation device for pollutants in riverbed sediment, comprising: Excavator body 100; The drive mechanism 200 includes a fixed plate 201 disposed at the output end of the excavator body 100, a first motor 202 adapted to be installed on the outer surface of the fixed plate 201, a fixed frame 203 fixedly installed on both sides of the outer surface of the first motor 202, and a mixing assembly 204 for breaking up mud and sludge. The stirring assembly 204 includes a drive block 204a fixedly connected to the output end of the first motor 202, a second motor 204b rotatably connected to the drive block 204a, and a connecting rod 204c fixedly connected to the output end of the second motor 204b.

[0018] Specifically, the stirring assembly 204 also includes a stirring wheel 204d fixedly installed on the end of the connecting rod 204c away from the second motor 204b, a movable frame 204e rotatably connected to the outer surface of the fixed frame 203, and a positioning pin 204f rotatably connected to the inner surface of the movable frame 204e.

[0019] When the first motor 202 is running, it drives the drive block 204a to rotate. During the rotation of the drive block 204a, it drives the second motor 204b to move. During the movement of the second motor 204b, the stirring wheel 204d can swing and move at multiple angles through the connecting rod 204c, thereby stirring the bottom mud in all directions and at multiple angles. The movable frame 204e and the positioning pin 204f ensure the stability of the second motor 204b during the movement, which not only ensures the reliability and accuracy of the equipment operation, but also improves the mixing effect of the solidifying agent and the bottom mud.

[0020] Furthermore, the fixed plate 201 is fixedly connected to the output end of the excavator body 100 by bolts, and the fixed frame 203 is rotatably connected to the movable frame 204e, with a bearing sleeve for rotational use provided at the connection.

[0021] The drive block 204a and the second motor 204b are rotatably connected through a bearing sleeve, so that the second motor 204b can rotate relative to the drive block 204a to achieve multi-angle adjustment of the stirring assembly 204.

[0022] Furthermore, the drive block 204a is rotatably connected to the second motor 204b, and a bearing sleeve for rotation is provided at the connection point.

[0023] Preferably, the outer edge of the stirring wheel 204d has multiple protrusions evenly distributed circumferentially to break up the bottom mud during rotation.

[0024] It should be noted that the two ends of the positioning pin 204f are rotatably connected to the movable frame 204e and the second motor 204b, respectively, and bearing sleeves are provided at the connection points for rotation.

[0025] In use, the in-situ solidification and remediation equipment for riverbed sediment pollutants is moved and positioned by the excavator body 100. The drive mechanism 200 is installed at the output end of the excavator body 100. The fixed plate 201 is firmly connected to the excavator body 100 by bolts to ensure the stability of power transmission. The first motor 202 is adapted to be installed on the outer periphery of the fixed plate 201. Fixed frames 203 are symmetrically arranged on both sides to support the overall structure of the subsequent mixing component 204. The mixing component 204 includes a drive block 204a, a second motor 204b, and a connecting rod 204c. After the first motor 202 is started, it drives the drive block 204a to rotate. The drive block 204a is rotatably connected to the second motor 204b through a bearing sleeve, so that the second motor 204b can rotate and move spatially under the drive of the drive block 204a, thereby realizing the multi-angle adjustment function of the mixing component 204. The output end of the second motor 204b is fixedly connected to the connecting rod 204c, and the end of the connecting rod 204c is equipped with a mixing wheel 2. 04d has multiple protrusions evenly distributed around its outer edge to enhance the crushing effect on the bottom mud. With the movement of the second motor 204b, the connecting rod 204c drives the stirring wheel 204d to swing and move at multiple angles in three-dimensional space, thereby carrying out all-round and three-dimensional stirring of the bottom mud and improving the mixing efficiency and reaction uniformity between the solidifying agent and the bottom mud. To ensure the stability and structural reliability of the stirring component 204 during operation, the equipment is also equipped with a movable frame 204e and a positioning pin 204f. The movable frame 204e is rotatably connected to the outside of the fixed frame 203 through a bearing sleeve, while the positioning pin 204f is rotatably connected to the inner surface of the movable frame 204e and forms a double-point connection structure with the second motor 204b. Both ends are flexibly rotated through bearing sleeves, which not only improves the adaptability of the stirring component 204 in complex terrain, but also effectively enhances the guiding and supporting role of the second motor 204b during movement, ensuring the stability and accuracy of the entire system operation.

[0026] In summary, by setting up a mixing assembly 204 consisting of a first motor 202, a drive block 204a, a second motor 204b, and a connecting rod 204c, the mixing wheel 204d can swing and move at multiple angles, enabling all-round, three-dimensional crushing and uniform mixing of the bottom sediment. This effectively improves the mixing degree and reaction efficiency between the solidifying agent and the bottom sediment, thereby enhancing the effect and quality of river bottom sediment pollution control and remediation.
