Description

Technical Field

[0001] The present invention relates to the technical field of dredging devices, and in particular to a dredging device and method for lake ecological restoration. Background Art

[0002] Silt solidification is an important step in removing silt in lake ecological restoration. The treatment of silt is generally divided into the processes of solidification, dehydration, stabilization, drying and incineration. The existing sludge solidification method is to heat the sludge to evaporate the water inside it and solidify it. The existing sludge solidification device usually includes a heating barrel. The sludge is placed in the heating barrel and heated to solidify the sludge. This static heating will cause the sludge in the heating barrel to be heated unevenly, so that the solidification time is longer. Some sludge solidification devices also include a rotating rod and a stirring rod. The stirring rod is vertically fixed to the rotating rod. A heating wire is installed in the stirring rod to control the rotation of the rotating rod. The rotating rod drives the stirring rod to rotate in the heating barrel, so that the sludge is heated more evenly and the solidification time of the sludge is reduced. However, the rotation of the stirring rod can only rotate with the rotation of the rotating rod, and can only achieve stirring in the circumferential direction. The part between the two stirring rods in the vertical direction is not in direct contact with the stirring rod, and some sludge is still heated unevenly, which affects the solidification time. Summary of the invention

Figures 1 to 11 As shown, an embodiment of the present invention provides a desilting device for lake ecological restoration, comprising: a heating barrel 1, a rotating rod 2, a plurality of stirring rods 5 and a planetary gear transmission system 3, wherein the rotating rod 2 is a hollow rod located in the heating barrel 1; the plurality of stirring rods 5 are connected to the side wall of the rotating rod 2 through a bearing, and one end of the plurality of stirring rods 5 extends into the rotating rod 2; the planetary gear transmission system 3, the inner gear ring of the planetary gear transmission system 3 is rotatably connected to the top of the heating barrel 1, the rotating rod 2 is fixedly connected to the inner gear ring 34 of the planetary gear transmission system 3, and the star gear 33 of the planetary gear transmission system 3 is fixedly connected with a plurality of connecting rods 4, and the plurality of connecting rods 4 are connected to the stirring rod 5 one by one through a universal cross shaft 6, so that the stirring rod 5 rotates while the rotating rod 2 rotates. A heating wire is installed inside the stirring rod 5 to heat the stirring rod 5. The sun gear 31 of the planetary gear transmission system 3 is connected with a motor 32.

[0038] By setting a stirring rod 5 and a planetary gear 33 transmission system 3, in the planetary gear 33 transmission system 3, the planetary gear 33 is connected to the planetary carrier 30 through a bearing, the planetary gear 33 rotates while the sun gear 31 rotates, the inner ring 34 rotates under the action of the planetary gear 33, and the inner ring 34 rotates in the same direction as the sun gear 31. The rotating rod 2 is connected to the inner ring 34, and the rotating rod 2 rotates with the inner ring 34. The connecting rod 4 is connected to the planetary gear 33, so the connecting rod 4 rotates along its own axis while the inner ring 34 rotates. The stirring rod 5 is connected to the side wall of the rotating rod 2 through a bearing and is connected to the connecting rod 4 through a universal cross shaft 6, so that the stirring rod 5 can rotate along its own axis while the rotating rod 2 rotates. There is a heating wire in the stirring rod 55. When in use, the heating wire is heated, and the sludge in the heating barrel 1 is stirred along the circumferential direction of the heating barrel 1, and the vertical direction is also stirred, so that the sludge in the heating barrel 1 is heated more evenly, further reducing the sludge solidification time, and making the dredging process more efficient.

[0039] The lengths of the multiple connecting rods 4 are inconsistent, which makes the heights of the stirring rod 5 in the heating barrel 1 also inconsistent, so that the stirring rod 5 stirs the sludge in the heating barrel 1 more evenly, and the sludge in the heating barrel 1 is heated more evenly, further improving the dredging efficiency and making the dredging process more efficient.

[0040] Multiple connecting rods 4 are arranged in sequence from short to long, so that the distance between two adjacent stirring rods 5 is small, so that the sludge in the heating barrel 1 is stirred more evenly, the sludge is heated more evenly, and the speed of sludge solidification is further accelerated, making the dredging efficiency more efficient.

[0041] The distance between two adjacent stirring rods 5 is equal, avoiding the situation where the distance between the two stirring rods 5 is uneven and the area between the two stirring rods 5 is not stirred, so that the sludge is heated more evenly, further accelerating the speed of sludge solidification, and making the dredging process more efficient.

[0042] The end of the connecting rod 4 farthest away from the planetary gear 33 is 2cm-10cm away from the top of the heating barrel 1, which avoids the rotation of the stirring rod 5 being affected by the stirring rod being too close to the top of the heating barrel 1. It also avoids the stirring rod 5 being too far away from the top of the heating barrel 1, causing the sludge on the top of the heating barrel 1 to be heated unevenly, further accelerating the speed of sludge solidification and making the dredging process more efficient.

[0043] The end of the longest connecting rod 4 away from the planetary gear 33 is 2cm-3cm away from the bottom of the heating barrel 1. Because sludge may accumulate at the bottom of the heating barrel 1, this length does not affect the rotation of the stirring rod 5 and can prevent sludge from accumulating at the bottom of the heating barrel 1 as much as possible, so that the sludge at the bottom of the heating barrel 1 is heated evenly, further accelerating the speed of sludge solidification, and making the dredging process more efficient.

[0044] The stirring rod 5 connected to the longest connecting rod 4 is connected to a scraper 7 on the side close to the bottom of the heating barrel 1, and the scraper 7 abuts against the bottom of the heating barrel 1. Because in order not to affect the rotation of the stirring rod 5, there is a certain distance between the stirring rod 5 connected to the longest connecting rod 4 and the bottom of the heating box, which makes it impossible to completely avoid the accumulation of sludge at the bottom of the heating barrel 1. The setting of the scraper 7 enables the stirring rod 5 to intermittently scrape the sludge at the bottom during the rotation process, avoiding the accumulation of sludge, so that the sludge at the bottom of the heating barrel 1 is heated more evenly, further accelerating the speed of sludge solidification, and making the dredging process more efficient.

[0045] The outer periphery of the stirring rod 5 is toothed to increase the contact area with the sludge. The increased contact area with the sludge makes it easier for the heat on the stirring rod 5 to be transferred to the sludge, further accelerating the solidification speed of the sludge.

[0046] A method for using a dredging device for lake ecological restoration, using any one of the dredging devices for lake ecological restoration according to any one of the claims, comprising the following steps:

[0047] Put the sludge in a heating barrel 1;

[0048] The sun gear 31 is controlled to rotate, and the planetary gear 33 rotates while the sun gear 31 rotates, and the inner gear ring 34 rotates at the same time, and the connecting rod 4 rotates while the inner gear ring 34 rotates; the rotation of the inner gear ring 34 drives the rotating rod 2 to rotate;

[0049] Since the stirring rod 5 is connected to the connecting rod 4 through the universal cross shaft 6, the stirring rod 5 rotates while rotating with the rotating rod 2, stirring the sludge in the heating barrel 1 in the circumferential direction and in the vertical direction, so that the sludge in the heating barrel 1 is heated evenly and the solidification speed of the sludge is accelerated.

[0050] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
