Description

Technical Field

[0001] This utility model relates to the technical field of sludge treatment equipment, specifically to a sludge treatment device for water conservancy construction. Background Technology

[0002] Serious river siltation problems lead to waterlogging, water pollution, and other environmental issues. Traditional dredging methods are costly and have significant environmental impacts, necessitating in-situ solidification solutions for efficient silt treatment. In-situ solidification primarily utilizes biopolymers and inorganic materials to react with organic matter and heavy metal ions in the silt, forming a solidified material that is permanently fixed to the riverbed. Before treatment, the silt undergoes physical property testing, including particle size distribution, solid content, organic matter content, and heavy metal content, to understand its characteristics. Based on the test results, a suitable solidifying agent is selected. The selected solidifying agent is then thoroughly mixed with the silt, using mechanical stirring or injection methods to ensure complete contact and reaction between the solidifying agent and silt, forming a stable solidified material. The existing silt solidification equipment's stirring head 2 is shown in the attached image. Figure 1 As shown, the mixing head 2 is fixed to the mechanical arm of the hydraulic excavator 1 via the extension arm 3 and the connecting seat 4. The hydraulic excavator 1 supplies hydraulic power to the mixing head 2 to mix the sludge. A hardener delivery pipe is installed on the extension arm 3 to deliver the hardener to the mixing head 2. While mixing the sludge, the hardener and sludge are mixed evenly, achieving in-situ hardening of the sludge. Because the mixing head 2 is fixedly connected to the extension arm 3, and the extension arm 3 is also fixedly connected to the connecting seat 4, the hydraulic excavator 1 can only mix the area corresponding to the mixing head 2 after adjusting the position of the mechanical arm. This results in a small operating range and low flexibility. Utility Model Content

Detailed Implementation

[0033] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0034] like Figure 1 As shown, the sludge treatment device for water conservancy construction includes a mixing head 2, an extension arm 3, and a connecting seat 4. The mixing head 2 is fixed to one end of the extension arm 3, and the other end of the extension arm 3 is connected to the mechanical arm of the hydraulic excavator 1 through the connecting seat 4.

[0035] To overcome the problem of the excessively small stirring range of the stirring head 2 in the prior art, the inventors improved the structure of the connecting seat 4. Specifically, as follows: Figure 2 and Figure 3 As shown, the connecting seat 4 includes a first connecting member 41, a second connecting member 42, and a third connecting member 43; wherein, the first connecting member 41 is used to connect with the mechanical arm of the hydraulic excavator 1, and the third connecting member 43 is fixedly connected to the extension arm 3.

[0036] For example, such as Figure 4 As shown, the first connecting member 41 includes a first connecting plate 412. Two connecting ears 411 are provided on the upper side of the first connecting plate 412. The shape of the two connecting ears 411 and the position and size of the connecting holes thereon are adapted to the mechanical arm of the hydraulic excavator 1. A first bearing seat 413 is also provided on the upper side. A second bearing seat 414 is provided on the lower side of the first connecting plate 412. The bearing holes of the first bearing seat 413 and the second bearing seat 414 are connected.

[0037] For example, such as Figure 5 As shown, the second connecting member 42 includes an internal gear ring 421, with a first connecting flange 422 and a second connecting flange 423 fixedly connected to both ends of the internal gear ring 421 respectively; both the first connecting flange 422 and the second connecting flange 423 extend radially outward from the internal gear ring 421; the second connecting member 42 is fixedly connected to the first connecting plate 412 through the first connecting flange 422, and the connection method can be welding, snap-fit, preferably bolt and nut connection, which is detachable and convenient for maintenance.

[0038] For example, such as Figure 6 As shown, the third connector 43 includes a second connecting plate 431, and a rotating shaft 432 is provided on the upper side of the second connecting plate 431 for rotatable connection with the first connector 41. Specifically, as... Figure 7 As shown, the rotating shaft 432 passes through the first connecting plate 412 from bottom to top and is rotatably disposed within the bearing holes of the first bearing seat 413 and the second bearing seat 414. A limiting plate 49 is fixedly connected to the upper end of the rotating shaft 432. A thrust bearing 46 is provided inside the first bearing seat 413, located between the limiting plate 49 and the first bearing seat 413. The limiting plate 49 restricts the lower limit of the rotating shaft 432, preventing it from sliding downwards and detaching from the first connecting member 41. A ball bearing 47 is provided inside the second bearing seat 414, enabling a rotatable connection between the rotating shaft 432 and the second bearing seat 414.

[0039] A rotary drive element 44 is fixedly mounted on the second connecting plate 432. A drive gear 48 is fixed on the output shaft of the rotary drive element 44. The drive gear 48 meshes with and transmits power to the internal gear ring 421. The rotary drive element 44 is preferably a hydraulic motor, which can be directly driven by the power of the hydraulic excavator 1, simplifying the overall structure of the device.

[0040] Furthermore, the rotation drive element 44 is located on the side of the second connecting plate 432 opposite to the first connecting plate 412. The second connecting plate 432 is provided with several through holes 433, and the output shaft of the rotation drive element 44 passes through the through holes 433 and extends into the interior of the internal gear ring 421. The rotation drive element 44 is located on the outside of the internal gear ring 421, which makes the overall structure of the connecting seat 4 compact, and the internal gear ring 421 has a small axial dimension and is lightweight.

[0041] In use, the hydraulic excavator 1 provides power to the rotating drive element 44, which in turn drives the drive gear 48 to rotate. Since the internal gear ring 421 is fixed on the first connecting plate 412, the second connecting plate 432 and the rotating shaft 432 rotate, thereby causing the extension arm 3 and the mixing head 2 to rotate at a certain angle; Figure 8 As shown, in the prior art, the stirring head 2 can only stir and solidify the sludge in area A. When the stirring head 2 rotates at a certain angle, its stirring area expands to area B, and the stirring area increases significantly. As the rotation angle of the stirring head 2 gradually increases, it can cover the entire circumferential range. The rotation angle α of the stirring head 2 is preferably 75-125°, which is not a large rotation range but can cover the entire circumferential area.

[0042] To ensure stable rotation of the second connecting plate 432, preferably, two rotation driving elements 44 are provided on the second connecting plate 432, and the two rotation driving elements 44 are evenly distributed in the circumferential direction of the rotating shaft 432, resulting in good force stability. Correspondingly, two through holes 433 are provided on the second connecting plate 432.

[0043] Furthermore, a guide hole 434 is machined on the second connecting plate 432. The guide hole 434 is arc-shaped and coaxial with the rotating shaft 432; the central angle corresponding to the guide hole 434 is 75-125°. A limiting shaft 45 is slidably provided in the guide hole 434. The lower end of the limiting shaft 45 extends to the lower side of the second connecting plate 432 and is provided with a limiting boss. The outer diameter of the limiting boss is larger than the width of the guide hole 434, thereby forming support and limiting on the lower side of the second connecting plate 432. The upper end of the limiting shaft 45 is fixedly connected to the second connecting flange 423, for example, by a threaded connection. Preferably, there are two guide holes 434, which are evenly distributed in the circumferential direction of the rotating shaft 432.

[0044] The extension arm 3 is fixedly connected to the lower side of the second connecting plate 432. Preferably, the lower side of the second connecting plate 432 is provided with a positioning groove to facilitate the positioning of the extension arm 3.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
