Technical Field
[0001] This utility model belongs to the technical field of sewage treatment equipment, and in particular relates to an integrated machine for environmentally friendly dredging and dewatering of polluted bottom sediment in black and odorous water bodies. Background Technology
[0002] Black and odorous water body polluted sediment refers to the muddy material that has been deposited at the bottom of urban or natural water bodies due to long-term pollution, and is black in color and emits a foul odor. This type of sediment is usually composed of clay, silt, organic matter and various pollutants, and is one of the important endogenous sources of pollution in the black and odorous water body phenomenon.
[0003] A search revealed that Chinese patent (publication number: CN216586726U) discloses a river sludge dredging device for black and odorous water body treatment projects. The device includes a cleaning boat with a dewatering mechanism installed at the top and a filtration mechanism installed at the bottom. A drying mechanism is installed on one side of the dewatering mechanism. The dewatering mechanism is connected to a sludge pump through a sludge suction pipe. The sludge from the bottom of the black and odorous water body is pumped into the dewatering mechanism by the sludge pump. The dewatering mechanism drains excess water and dries it in the filtration mechanism, making it easier for workers to utilize the sludge and thus realizing the utilization of sludge resources.
[0004] However, during the use of this device, the sludge pump directly sucks the sludge into the dewatering tank; however, the dewatering tank is a horizontally placed cylinder, and the dewatering tank and the sludge pump are only connected by a hose, making it difficult to ensure that the sludge can be evenly distributed inside the dewatering tank by the spiral blades. This easily leads to sludge accumulation in the dewatering tank, thereby reducing the sludge treatment effect. Therefore, an integrated environmental dredging and dewatering machine for polluted bottom sediment in black and odorous water bodies is needed to solve the above problems. Utility Model Content
[0005] The purpose of this utility model embodiment is to provide an integrated machine for environmentally friendly dredging and dewatering of polluted sediment in black and odorous water bodies, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0010] The second filtration mechanism is fixedly installed on the cleaning vessel and is positioned at a predetermined distance below the filter cylinder.
[0011] The conveying mechanism includes a conveying cylinder, a rotating rod, helical blades, and a second driving component.

The second driving component is mounted outside the conveying cylinder, and its output shaft is connected to the rotating rod. The conveying cylinder is fixedly mounted on the second filtration mechanism and connected to it via a pipe. The lower end of the filtration cylinder is connected to the end of the conveying cylinder, and the conveying cylinder has a mud outlet at the end away from the end connected to the filtration cylinder.
[0012] A dewatering mechanism is fixedly installed on the cleaning vessel and connected to the sludge outlet pipe.
[0013] A further technical solution includes a placement plate inside the filter cylinder, a placement groove on the lower end face of the filter disc, the placement groove being adapted to the placement plate, a scraping ring on the filter disc being in contact with the inner wall of the filter cylinder, the upper end of the scraping ring being blade-shaped, a detachable cover plate on the upper end of the filter cylinder, and the upper end of the rotating column being connected to the lower end face of the cover plate via a rotating shaft.
[0014] In a further technical solution, the conveying mechanism also includes a filter plate, which is horizontally installed inside the conveying cylinder and positioned below the spiral blades.
[0015] In a further technical solution, the lower end of the conveying cylinder has multiple spaced mud discharge ports, each of which is connected to the pipe of the second filtration mechanism.
[0016] In a further technical solution, the upper end of the filter disc has a fixed post, and the filter disc has a rotating ball at the upper end of the fixed post. The rotating post has an insertion groove, the fixed post is inserted into the insertion groove, and the rotating ball is in contact with the inner wall of the insertion groove.
[0017] In a further technical solution, the dewatering mechanism includes a dewatering tank, a dewatering cylinder, and a third driving component. The upper end of the dewatering cylinder is connected to the mud outlet pipe, and the lower end of the dewatering cylinder is rotatably mounted on the bottom wall of the dewatering tank via a rotating shaft. The third driving component is installed outside the dewatering tank, and the output shaft of the third driving component is connected to the dewatering cylinder.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] This invention features a first filtration mechanism comprising a filter cylinder, a filter disc, a rotating column, multiple leveling rollers, and a first driving component. The filter disc is installed inside the filter cylinder. One end of each leveling roller is fixedly mounted to the lower end of the rotating column, and the rollers are circumferentially distributed around the axial direction of the rotating column. The upper end of the rotating column is rotatably mounted inside the filter cylinder, and the leveling rollers are positioned a predetermined distance above the filter disc. The first driving component is installed outside the filter cylinder, and its output shaft is connected to the rotating column. The filter cylinder is connected to a sludge pump via a flexible hose and is fixedly mounted on a cleaning vessel. Workers first move the cleaning vessel to the desired cleaning position. The activated sludge pump draws sludge into the filter cylinder and places it on the upper surface of the filter disc. Subsequently, the activated first driving component drives the rotating column to rotate, which in turn causes the multiple leveling rollers to rotate synchronously around the axial direction of the rotating column, ensuring even distribution of sludge on the upper surface of the filter disc. Thus, by incorporating the leveling rollers, sludge accumulation in one area of the filter disc is prevented, improving filtration efficiency.
[0020] This invention features a scraping ring and a fixing post. The scraping ring fits snugly against the inner wall of the filter cylinder, with its upper end shaped like a blade. The upper end of the filter cylinder has a detachable cover plate, and the upper end of the rotating post is connected to the lower end of the cover plate via a rotating shaft. The filter disc has a rotating ball at the upper end of the fixing post, and the rotating post has an insertion groove into which the fixing post is inserted, with the rotating ball fitting snugly against the inner wall of the groove. When the filter disc is clogged with excessive sediment and requires cleaning, the worker removes the cover plate from the upper end of the filter cylinder. At this point, the rotating post, the leveling roller, and the first driving component detach from the filter disc, and the fixing post and the rotating ball detach from the insertion groove. The worker then grasps the fixing post and pulls it upwards to remove the filter disc from the filter cylinder for cleaning. During this process, the scraping ring scrapes off impurities remaining on the side wall of the filter cylinder, reducing maintenance difficulty.

[0030] like Figures 1 to 5 As shown in the figure, this utility model embodiment provides an integrated environmental dredging and dewatering machine for polluted sediment in black and odorous water bodies, comprising:
[0031] Equipment body 1, which includes a cleaning vessel 11 and a mud pump 12;
[0032] The first filtration mechanism 2 includes a filter cylinder 21, a filter disc 22, a rotating column 23, multiple leveling rollers 24, and a first driving member 25. The filter disc 22 is installed inside the filter cylinder 21. One end of each of the multiple leveling rollers 24 is fixedly installed at the lower end of the rotating column 23. The multiple leveling rollers 24 are circumferentially distributed around the axial direction of the rotating column 23. The upper end of the rotating column 23 is rotatably installed inside the filter cylinder 21. The leveling rollers 24 are positioned at a predetermined distance above the filter disc 22. The first driving member 25 is installed outside the filter cylinder 21. The output shaft of the first driving member 25 is connected to the rotating column 23. The filter cylinder 21 is connected to the sludge pump 12 through a hose. The filter cylinder 21 is fixedly installed on the cleaning vessel 11.
[0033] The second filter mechanism 3 is fixedly installed on the cleaning vessel 11 and is positioned at a predetermined distance below the filter cylinder 21.
[0034] The conveying mechanism 4 includes a conveying cylinder 41, a rotating rod 42, a spiral blade 43, and a second driving member 44. The spiral blade 43 is evenly distributed on the rotating rod 42, which is rotatably installed inside the conveying cylinder 41. The second driving member 44 is installed outside the conveying cylinder 41, and its output shaft is connected to the rotating rod 42. The conveying cylinder 41 is fixedly installed on the second filtering mechanism 3 and is connected to the second filtering mechanism 3 through a pipe. The lower end of the filtering cylinder 21 is connected to the end of the conveying cylinder 41. The conveying cylinder 41 has a mud outlet 411 at the end away from the end connected to the filtering cylinder 21.
[0035] Dewatering mechanism 5 is fixedly installed on cleaning vessel 11 and connected to sludge outlet 411 pipe.
[0036] In this embodiment, the worker first moves the cleaning boat 11 to the position to be cleaned; the sludge pump 12, after being started, pumps the sludge into the filter cylinder 21 and places it on the upper surface of the filter disc 22; then, the first driving component 25, after being started, drives the rotating column 23 to rotate, thereby driving multiple leveling rollers 24 to rotate synchronously around the rotating column 23 axially, so that the sludge on the upper surface of the filter disc 22 is evenly distributed; in this way, by setting up the leveling rollers 24, the sludge is prevented from accumulating in a certain place on the filter disc 22, thus improving the filtration efficiency;
[0037] Specifically, the filter cylinder 21 has a placement plate 211 inside, the filter disc 22 has a placement groove 221 on the lower end face, the placement groove 221 is adapted to the placement plate 211, the filter disc 22 has a scraping ring 222, the scraping ring 222 is in contact with the inner wall of the filter cylinder 21, the upper end of the scraping ring 222 is set as a blade, the upper end of the filter cylinder 21 has a detachable cover plate 212, and the upper end of the rotating column 23 is connected to the lower end face of the cover plate 212 through a rotating shaft;
[0038] In this embodiment, when there is too much mud and sand on the filter disc 22 and it needs to be cleaned, the worker removes the cover plate 212 from the upper end of the filter cylinder 21. At this time, the rotating column 23, the leveling roller 24 and the first driving component 25 are all detached from the filter disc 22, and the fixing column 223 and the rotating ball 224 are detached from the insertion groove 231. The worker pulls the filter disc 22 upward to remove the filter disc 22 from the inside of the filter cylinder 21 and clean it. During this process, the scraping ring 222 scrapes off the impurities remaining on the side wall of the filter cylinder 21. The operation is simple and reduces the difficulty of operation and maintenance.
[0039] Specifically, the conveying mechanism 4 also includes a filter plate 45, which is horizontally installed inside the conveying cylinder 41 and positioned below the spiral blade 43.
[0040] In this embodiment, excess water in the sludge in the conveying cylinder 41 is drained through the filter plate 45 under the action of gravity and flows to the second filtration mechanism 3 for further filtration through multiple sludge discharge ports 412. The sludge is squeezed out through the sludge discharge port 411 by the rotating spiral blades 43.
[0041] Specifically, the lower end of the conveying cylinder 41 has a plurality of spaced mud discharge ports 412, each of which is connected to the pipe of the second filter mechanism 3.
[0042] Specifically, the upper end of the filter disc 22 has a fixed post 223, and the filter disc 22 has a rotating ball 224 at the upper end of the fixed post 223. The rotating post 23 has an insertion groove 231, the fixed post 223 is inserted into the insertion groove 231, and the rotating ball 224 is in contact with the inner wall of the insertion groove 231.
[0043] In this embodiment, as the rotating column 23 drives the multiple leveling rollers 24 to rotate, the rotating ball 224 rotates in the insertion groove 231; by setting the rotating ball 224, the friction between the rotating column 23 and the fixed column 223 is reduced, thereby extending the service life of the equipment;
[0044] Specifically, the dewatering mechanism 5 includes a dewatering box 51, a dewatering cylinder 52, and a third driving member 53. The upper end of the dewatering cylinder 52 is connected to the mud outlet 411 pipe, and the lower end of the dewatering cylinder 52 is rotatably mounted on the bottom wall of the dewatering box 51 via a rotating shaft. The third driving member 53 is mounted outside the dewatering box 51, and the output shaft of the third driving member 53 is connected to the dewatering cylinder 52.
[0045] In this embodiment, after startup, the third drive unit 53 drives the dewatering cylinder 52 and the sludge in the dewatering cylinder 52 to rotate at high speed. Under the action of centrifugal force, the water in the sludge is thrown to the dewatering tank 51 and finally flows out through the drain of the dewatering tank 51. In this way, the dewatered sludge can be reused, thereby realizing the recycling of sludge resources.
[0046] The working principle of this utility model is as follows:
[0047] In use, the worker first moves the cleaning boat 11 to the position to be cleaned; the sludge pump 12, after being started, pumps the sludge into the filter cylinder 21 and places it on the upper surface of the filter disc 22; then, the first drive unit 25, after being started, drives the rotating column 23 to rotate, which in turn drives multiple leveling rollers 24 to rotate synchronously around the rotating column 23 axially, so that the sludge on the upper surface of the filter disc 22 is evenly distributed; in this way, by setting up the leveling rollers 24, sludge is prevented from accumulating in one place on the filter disc 22, thus improving the filtration efficiency;
[0048] Furthermore, when there is too much mud and sand on the filter disc 22 and it needs to be cleaned, the worker removes the cover plate 212 from the upper end of the filter cylinder 21. At this time, the rotating column 23, the leveling roller 24 and the first driving component 25 are all detached from the filter disc 22, and the fixed column 223 and the rotating ball 224 are detached from the insertion groove 231. The worker holds the fixed column 223 and pulls it upward to remove the filter disc 22 from the inside of the filter cylinder 21 and clean it. During this process, the scraping ring 222 scrapes off the impurities remaining on the side wall of the filter cylinder 21. The operation is simple and reduces the difficulty of operation and maintenance.
[0049] During the process of the rotating column 23 driving multiple leveling rollers 24 to rotate, the rotating ball 224 rotates in the insertion groove 231; by setting the rotating ball 224, the friction between the rotating column 23 and the fixed column 223 is reduced, thereby extending the service life of the equipment;
[0050] Then, the filtered sludge falls into the conveying cylinder 41 through the pipe under the action of gravity; the second driving component 44 after startup drives the rotating rod 42 and the spiral blades 43 evenly distributed on the rotating rod 42 to rotate, so as to convey the sludge towards the sludge outlet 411.
[0051] During this process, excess water in the sludge in the conveying cylinder 41 is drained through the filter plate 45 under the action of gravity and flows to the second filtration mechanism 3 for further filtration through multiple sludge discharge ports 412. The sludge is squeezed out by the rotating spiral blades 43 through the sludge discharge port 411 and enters the dewatering cylinder 52 through the pipe.
[0052] After startup, the third drive unit 53 drives the dewatering cylinder 52 and the sludge in the dewatering cylinder 52 to rotate at high speed. Under the action of centrifugal force, the water in the sludge is thrown to the dewatering tank 51 and finally flows out through the drain of the dewatering tank 51. In this way, the dewatered sludge can be reused, thereby realizing the recycling of sludge resources.
[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
