Description

Technical Field

[0001] The invention relates to the field of mud dehydration, and in particular to a dredging mud rapid dehydration device. Background Art

[0002] Dredging projects typically use equipment such as excavators, dredgers, and pumps to remove impurities such as silt and sand from the bottoms of rivers and lakes. These impurities may have accumulated due to erosion by river and lake currents, sediment deposition, and the growth of aquatic plants. Dredging methods include mechanical dredging, hydraulic dredging, and manual dredging. Dredging can increase water depth and improve water quality, enhance the navigability of waterways, and protect the safe operation of ports and waterways. Dredging can also improve the flood discharge capacity of rivers and lakes and protect the ecological environment of riverbanks and coastal areas.

[0003] The purpose of dredging is to maintain or restore the navigability of waterways, prevent siltation and blockage, and ensure the safe passage of ships. However, the mud produced by dredging needs to be dehydrated and dissolved to reduce the footprint of the mud dumping area and ensure the smooth progress of dredging operations. When dehydrating dredged mud, a dehydration device is required. Existing dredged mud dehydration devices are unable to pre-dehydrate the mud during use. This results in mud with a high water content being squeezed out before it reaches the dehydration standard during the dehydration process. The dehydrated mud has a high water content and is difficult to transport or recycle. Summary of the Invention

[0031] A drain pipe 133 is provided at the bottom of the water collecting trough 123, and the blocking block 115 is clamped with the top of the mud discharge port 122 inside the water filter bucket 124. Limiting rods are evenly provided on the inner center edge of the water filter bucket 124, and limiting rings are provided on the inner bottom end of the water filter bucket 124 and the outer surface of the top of the limiting rod.

[0032] Through the above technical solution, a drain pipe 133 can be set at the bottom of the water collection trough 123 to transport the discharged water to the inside of the water collection box 23 for collection. The sealing block 115 is clamped with the top of the mud discharge port 122 inside the water filter bucket 124, and the inner bottom end of the water filter bucket 124 can be sealed. Limiting rods are evenly set on the inner center edge of the water filter bucket 124, which can limit the lifting and lowering of the sealing block 115. Limiting rings are set on the inner bottom end of the water filter bucket 124 and the outer surface of the top of the limiting rod, which can limit the sliding of the first connecting rope 117, and the highest rising height of the sealing block 115 does not contact the bottom end of the rotating shaft 127.

[0033] The first connecting rope 117 is inserted into the interior of the water filter barrel 124 and the interior of the limiting ring.

[0034] Through the above technical solution, the first connecting rope 117 can be inserted through the inside of the water filter bucket 124 and the limiting ring, thereby limiting the sliding of the first connecting rope 117, and ensuring that when the first connecting rope 117 is pulled, the blocking block 115 can be pulled upward under the limitation of the limiting ring at the top of the limiting rod, and the middle part of the second connecting rope 120 slides and overlaps the outer surface of the limiting shaft 128, which can ensure that the second connecting rope 120 is smoothly pulled, and the bottom end of the water supply pipe 129 is fixedly connected to the water pump inside the water collection tank 123, which can supply water to the inside of the water supply pipe 129, and the second drive motor 125 is rotatably connected to the rotating shaft 127 through the transmission sprocket 130 and the transmission chain 131, so that the rotation of the rotating shaft 127 can be controlled to mix the mud inside the water filter bucket 124.

[0035] The winding shaft 111 is rotatably connected to the top of the water collecting tank 123 through the limiting shaft sleeve 121. The drainage pipe 133 at the bottom end of the water collecting tank 123 is connected to the top of the water collecting box 23. The annular pipe 118 is aligned with the check valve 132 through the connecting pipe 113 and is movably connected.

[0036] Through the above technical solution, the winding shaft 111 can be rotated and clamped on the top of the water collecting tank 123 through the limiting sleeve 121, thereby limiting the rotation of the winding shaft 111. The drain pipe 133 at the bottom end of the water collecting tank 123 is connected to the top of the water collecting box 23, and can collect the pre-discharged water. The annular tube 118 is aligned with the check valve 132 through the connecting pipe 113 and movably clamped, so as to facilitate the transportation of water to the inside of the annular tube 118, and then sprayed onto the inner surface of the water filter barrel 124 through the arc scraper 114 for cleaning.

[0037] The outer surface of the bottom of the annular tube 118 is evenly provided with counterweight blocks 134 , the bottom end of the mud discharge port 122 is tilted and aligned with the upper surface of the water filter conveyor belt 25 , and the arc scraper 114 is in close contact with the inner surface of the filter screen plate 126 inside the water filter barrel 124 .

[0038] Through the above technical solution, the counterweight blocks 134 can be evenly arranged on the bottom outer surface of the annular tube 118, and the annular tube 118 can be ensured to descend and reset when the second connecting rope 120 is unwound. The arc scraper 114 is in close contact with the inner surface of the filter screen 126 inside the water filter barrel 124, and can ensure that the mud stains on the surface of the filter screen 126 can be scraped off when the arc scraper 114 is raised or lowered.

[0039] The working principle of the present invention is as follows: before the dredged mud is quickly dehydrated, the dredged mud is first poured into the interior of the filter bucket 124. At the same time, the second drive motor 125 is started by manipulating the electric control box 24 to drive the rotating shaft 127 to rotate synchronously through the transmission sprocket 130 and the transmission chain 131, so that the rotating shaft 127 stirs the mud inside the filter bucket 124. The water-containing slurry entering the filter bucket 124 will be filtered by the filter screen 126, and the water in the mud will pass through the filter screen 126 and be discharged. It will flow downward along the outer wall of the filter bucket 124 to the interior of the water collection tank 123. The water entering the water collection tank 123 will enter the interior of the water collection tank 23 through the drain pipe 133 at the bottom for collection. Most of the water inside the filter bucket 124 After the water is discharged, the first drive motor 112 is started to drive the three sets of winding shafts 111 to rotate synchronously through the universal flexible shaft 119, so that the three sets of winding shafts 111 respectively reel in the second connecting ropes 120 synchronously. At the same time, the second connecting rope 120 will pull the annular tube 118 connected at the bottom to rise synchronously, and the annular tube 118 will drive the arc scraper 114 to rise and scrape the mud stains on the surface of the filter screen 126 to prevent the mud stains from clogging the filter screen 126 and affecting normal drainage. When the annular tube 118 rises to the inner upper end edge of the water filter bucket 124, the annular tube 118 will pull the four sets of first connecting ropes 117 to drive the blocking block 115 to rise, so that the blocking block 115 is separated from the top of the mud discharge port 122, and the mud inside the water filter bucket 124 will pass through The mud outlet 122 is discharged to the upper surface of the water filter conveyor belt 25 until the annular tube 118 rises to the internal top of the water filter bucket 124, and at the same time, the connecting pipe 113 on the upper surface of the annular tube 118 squeezes the check valve 132, so that the inside of the check valve 132 is opened, wherein the water pump running inside the water collection tank 123 extracts the water inside the water collection tank 123 and transports it to the inside of the annular tube 118 through the water supply pipe 129, and sprays it to the inner surface of the water filter bucket 124 through the nozzle 116 at the bottom of the annular tube 118, thereby flushing the inner surface of the water filter bucket 124 to ensure the cleanliness of the inner surface of the water filter bucket 124. After cleaning, the first drive motor 112 is started to rotate in the reverse direction to unwind the second connecting rope 120, and at the same time the blocking block 11 5 will drive the annular tube 118 to descend synchronously under the action of gravity until the blocking block 115 is engaged with the top of the first drive motor 112, thereby blocking the inner bottom end of the water filter bucket 124. As the second connecting rope 120 is unwound, the annular tube 118 will descend to its initial position. In the process of descending, the annular tube 118 will drive the arc scraper 114 to clean the filter screen 126 again. When the connecting tube 113 is separated from the check valve 132, the inside of the check valve 132 will be closed to prevent water from continuing to discharge, and then wait for the next group of mud to be transported to the inside of the water filter bucket 124 for pre-dehydration. The dehydrated mud will be further transported by the water filter conveyor belt 25. At the same time, the water in the mud will pass through the water filter conveyor belt 25 and drip into the inside of the water tank 22.The slurry is squeezed and dehydrated until it enters between the water pressure belt 21 and the water filter conveyor belt 25. The bottom of the water filter conveyor belt 25 is immersed in the water tank 22 so that the water in the water tank 22 can clean the surface of the water filter conveyor belt 25 and ensure the cleanliness of the surface of the water filter conveyor belt 25. Therefore, through the coordinated operation between the water filter component 1 and the dehydration component 2, the dehydration device can pre-dehydrate slurries with different water contents, ensuring that the dehydration device can normally dehydrate slurries with similar water contents, while also ensuring the dehydration quality of the dehydration device.

[0040] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
