Description

Technical Field

[0001] The invention belongs to the technical field of sewage sludge treatment equipment, and in particular relates to a bottom sludge treatment equipment for a water conservancy construction river channel. Background Art

[0002] The riverbed desilting equipment is a mechanical device used to remove silt and other sediments accumulated at the bottom of the river. The long-term accumulation of silt at the bottom of the river will cause the riverbed to rise, reduce the flood-carrying capacity of the river, and increase the risk of floods. In addition, pollutants in the silt will also pollute the river water and affect the water quality. Therefore, regular desilting of the riverbed can not only ensure the drainage and flood control capacity of the river, but also maintain the ecological environment of the river and improve the water quality.

[0003] At present, the main methods of dredging the bottom of the river include mechanical excavation, pump suction and drainage, flushing and cleaning. Common dredging equipment includes excavators, dredging ships, dredging pumps, etc. Directly excavating the riverbed silt through a mechanical arm or bucket is highly efficient, but it is easy to stir up a large amount of silt, causing turbidity in the river water and affecting the water quality. The silt is sucked to the shore for treatment through a dredging pump, which is flexible to operate, but it is easy to cause suction difficulties due to the cohesion or high viscosity of the silt, and the suction force is limited. Flushing the silt with water flow or high-pressure water and then pumping it out is suitable for handling loose silt, but it is inefficient when facing viscous or agglomerated silt. Although there are various types of existing riverbed dredging equipment, there are generally some disadvantages. For example, mechanical excavation will damage the ecological environment of the river and cause serious water pollution; dredging pumps are prone to clogging and are difficult to handle viscous or agglomerated silt; high-pressure water flushing is inefficient and the cleaning is not thorough, and dredging work is prone to repetition.

[0004] Common problems and deficiencies of existing technologies: (1) Water source pollution: Existing mechanical excavation or dredging equipment using suction pumps can easily stir up a large amount of silt during operation, causing turbid water and polluting river water sources, making it difficult to maintain a clean working environment. (2) Incomplete dredging: Suction pumps are often unable to effectively suck out viscous or clumped silt, resulting in serious silt residue and incomplete cleaning, which affects subsequent maintenance. (3) Low operating efficiency: The operating speed of mechanical excavation or high-pressure water washing is limited, and the dredging efficiency is low, especially when the riverbed is complex or the silt thickness is uneven, it is difficult to achieve rapid dredging. (4) Ecological damage: Strong dredging methods such as mechanical excavation cause great damage to the riverbed and riverbed biological habitats, which is not conducive to the protection and restoration of the river ecological environment. (5) Complex equipment operation: Most existing equipment requires multiple devices to work together, such as excavation, crushing, and cleaning separately, which leads to complex operation, affected operating efficiency, and high equipment maintenance costs.

[0005] Based on the above-mentioned shortcomings of existing dredging technology, especially in terms of water source pollution, incomplete cleaning, low operating efficiency and complex equipment operation, the effectiveness of river dredging is restricted. In order to improve the efficiency of dredging operations, reduce environmental pollution and simplify operations, a self-propelled closed dredging high-pressure crushing and cleaning equipment is urgently needed to adapt to the diverse river environment, improve the dredging effect and reduce damage to the ecological environment.

DETAILED DESCRIPTION

[0034] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0035] Embodiment: A device for treating bottom silt in a river channel for water conservancy construction, the device having a walking mode and a dredging mode. The walking mode is used when walking long distances on the road surface, and the dredging mode is used when dredging work is carried out at the bottom of the river channel. In the dredging mode, the device can also walk slowly on the surface of the riverbed silt layer. In the dredging mode, the device can cut the surface layer of silt into sections and crush it with high-pressure water impact, and then suck it into the shore-based silt truck box in a closed space for separation and treatment. The device can effectively reduce the problem of river water source pollution caused by silt turbidity during the dredging operation of the river bottom.

[0036] like Figure 1 and Figure 2As shown, the device mainly includes components such as a vehicle body 1, a crawler track 2, a booster pump group 3, a suction pump group 4 and a crushing mechanism 5. The crawler track 2 is installed on the left and right sides of the vehicle body 1. Each crawler track 2 includes a crawler track bracket and an annular crawler track, and an annular crawler track is wrapped around the left and right crawler tracks. A driving mechanism, a tensioning mechanism, a supporting wheel group, etc. are installed in the crawler track bracket. The crawler track 2 can adopt any existing crawler track structure, but the annular crawler track must at least include a chain plate 21, a rib seat 22, an axle seat 23, an expansion plate 24, a chain link 27 and a chain shaft 28. As shown in FIG. Figure 3 As shown, the inner wall of each crawler chain plate 21 is fixed with a chain link 27, and adjacent chain links 27 are hinged together through a chain shaft 28. A rib seat 22 is transversely fixed to the outer wall of each chain plate 21, and an axle seat 23 is fixed to the left and right ends of the rib seat 22. An expansion plate 24 is hinged to the axle seat 23 through a pin, and the expansion plate 24 can be turned over. When the expansion plate 24 is in a flat state, as shown in FIG. Figure 3 As shown in (1), at this time, the expansion plate 24 and the surface of the chain plate 21 are matched and attached together, and the expansion plate 24 and the chain plate 21 are fixed together by the flat wire 25. When the expansion plate 24 is in the upright state, as shown in FIG. Figure 3 As shown in (2), the expansion plate 24 and the surface of the rib seat 22 are matched and fitted together, and the expansion plate 24 and the rib seat 22 are fixed together by the vertical wire 26. When in the walking state, each expansion plate 24 needs to be laid flat and fixed, and the track contacts the ground directly through the rib seat 22. However, when dredging in the river channel, each expansion plate 24 is erected and fixed, and the track walks on the underwater silt surface to cut the silt to form multiple cutting areas 29.

[0037] like Figure 4 and Figure 5 As shown, the vehicle body 1 includes a sludge bin 11, a pipe bin 12 and a motor bin 13. Between the track brackets of the track part 2, there is a bottom fixing frame 15 connected to the left and right track brackets in the sludge bin 11; there is a middle fixing frame 14 connected to the left and right track brackets in the pipe bin 12; and there is a top fixing frame 16 in the motor bin 13. Among them, the bottom of the sludge bin 11 is open, while the pipe bin 12 and the motor bin 13 are both in a sealed and isolated state. The power used to drive the track part 2 to move can be either an external power supply or a battery sealed and installed in the motor bin 13 as a working power supply.

[0038] like Figure 4-Figure 6As shown, the booster pump group 3 and the suction pump group 4 are respectively installed in each compartment of the vehicle body 1. The booster pump group 3 includes a booster pump 31, a water supply pipe 32, a filter 33 and a booster pipe 34. The booster pump 31 is fixed in the motor compartment 13, and the water supply pipe 32 and the booster pipe 34 are fixed in the pipeline compartment 12. The mouth of the water supply pipe 32 is located in the water source. For example, the water supply pipe 32 is placed below the water surface of the river; or, a spare water tank is installed inside or on the top of the motor compartment 13, and the mouth of the water supply pipe 32 is connected to the bottom of the spare water tank; or, the mouth of the water supply pipe 32 is inserted into the sludge compartment 11, and the filter 33 is set at the mouth of the water supply pipe 32.

[0039] like Figure 4 and Figure 6 As shown, the suction pump assembly 4 includes a suction pump 41, a suction main pipe 42, an upper layer pipe 43, a through joint 44, a bottom layer pipe 45, a suction nozzle 46 and an output pipe 47. The suction pump 41 is fixed in the motor compartment 13, the suction main pipe 42 and the upper layer pipe 43 are fixed in the pipe compartment 12, the suction port of the suction pump 41 is connected to the suction main pipe 42, and the suction main pipe 42 is connected to the upper layer pipe 43. Figure 6 As shown, a bottom layer pipe 45 is fixed at the top of the sludge bin 11, the upper layer pipe 43 and the bottom layer pipe 45 are connected by a through joint 44, and a series of suction nozzles 46 are evenly distributed on the bottom layer pipe 45. An output pipe 47 is fixed in the motor bin 13, the discharge port of the suction pump 41 is connected to the lower end of the output pipe 47, and the upper end of the output pipe 47 is connected to the sludge truck box on the shore through a conveying pipeline.

[0040] A crushing mechanism 5 is installed on one or both outer side walls 20 of the crawler support of the crawler part 2. Figure 7As shown, the crushing mechanism 5 includes a fixed seat 51, an elastic support rod 52, a rack 53, a nozzle cover 54, a high-pressure nozzle 55, a high-pressure hose 56 and a connecting seat 57. A fixed seat 51 is fixed on the outer wall 20 of the crawler bracket, and an elastic support rod 52 is connected to the lower end of the fixed seat 51. The elastic support rod 52 includes an outer sleeve and an inner sleeve rod, which are sleeved together. A spring is sleeved in the outer sleeve, and the spring supports the inner sleeve rod to move upward. Specifically, a ring platform extends inward from the lower end of the outer sleeve, and a stop platform is set at the top of the inner sleeve rod. The spring is sleeved on the inner sleeve rod and is located between the ring platform and the stop platform. Therefore, in a natural state, the outer sleeve and the inner sleeve are in a contracted state due to the downward pressure of the vehicle body. A connecting seat 57 is fixed at the bottom of the inner sleeve rod, and the connecting seat 57 is connected to the rack 53. A series of nozzle covers 54 are evenly fixed at the bottom of the rack 53, and a high-pressure nozzle 55 is installed on each nozzle cover 54. At the same time, the boost pipe 34 penetrates and is fixed to the outer wall 20 of the crawler bracket. The boost pipe 34 is fixedly connected to a longitudinal pipe 58. A series of high-pressure hoses 56 are evenly connected to the longitudinal pipe 58. The bottom of each high-pressure hose 56 is connected to the corresponding high-pressure nozzle 55. When the boost pipe 34 provides high-pressure water, it can provide an impact force to the high-pressure nozzle 55. This water pressure impact force forces the nozzle cover 54 and the rack 53 to move downward, and then all the high-pressure nozzles 55 move downward synchronously to enter the cutting area 29. In the natural state, each high-pressure nozzle 55 moves upward with the rack 53 and the nozzle cover 54 and is in a retracted state. Only in the high-pressure water spraying state, the rack 53 and the nozzle cover 54 carry the high-pressure nozzle 55 and move downward to the cutting area 29 to perform high-pressure crushing operations.

[0041] like Figure 8 As shown, a guard plate assembly is fixed to the outer wall of the chain plate 21, the rib seat 22 and the expansion plate 24. The guard plate assembly includes a side guard plate 201, a positioning column 202, a positioning groove 203, a fixing hole 204 and a water injection port 205. A positioning column 202 is fixed to the inner wall of the side guard plate 201, and positioning grooves 203 are respectively provided on the outer end faces of the chain plate 21, the rib seat 22 and the expansion plate 24, and each positioning column 202 is matched and inserted with the corresponding positioning groove 203. At the same time, a fixing hole 204 is provided between the side guard plate 201 and the chain plate 21, and the side guard plate 201 and the chain plate 21 are fixedly installed together by screws. The overlapping part between adjacent side guard plates 201 is provided with a thinned yielding area. Therefore, during the dredging process, the silt layer is cut into multiple independent partitions by using the adjacent expansion plates 24, and the outer sides of the multiple independent partitions are closed by using the side guard plates 201. When the high-pressure water impact crushes the silt in the cutting area 29, it can prevent the high-pressure water from flushing the silt out of the cutting area 29. It can be seen that the side guard plate 201 can increase the impact strength of the high-pressure water in the cutting area 29, and prevent the silt from being discharged from the cutting area 29 and polluting the river water.

[0042] When the crushing mechanism 5 is improved, a linkage mechanism 6 can be added. Figure 10-12 As shown, the linkage mechanism 6 includes a fixed support 61, an electromagnet 62, a head end pressure touch switch 63, a terminal end pressure touch switch 64, a sliding pin 65, a slide groove 66, a fixed plate 67, a movable plate 68 and a thrust spring 69. The fixed support 61 is fixed on the rack 53, and the electromagnet 62 is fixed on the inner side of the fixed support 61. The connecting seat 57 is a U-shaped structure, and sliding pins 65 are fixed on the two side walls of the U-shaped structure. At the same time, a slide groove 66 is provided on the rack 53, and the sliding pin 65 is inserted into the slide groove 66, so that the rack 53 can translate left and right. Fig.11 and Fig.12 In the embodiment, fixed plates 67 are fixed to the crawler brackets at both ends of the rack 53, and movable plates 68 are fixed to both ends of the rack 53. Fig.12 A thrust spring 69 is installed between the movable plate 68 and the fixed plate 67. Under the pushing action of the thrust spring 69, the rack 53 is naturally in a state of moving backwards. However, when the fixed support 61 attracts the side guard plate 201, the entire rack 53 can move with the side guard plate 201, and the thrust spring 69 is compressed. Fig.12 In the embodiment, a head end pressure touch switch 63 and a terminal pressure touch switch 64 are installed in the middle of the two fixed plates 67 at the front and rear ends respectively. The head end pressure touch switch 63 and the terminal pressure touch switch 64 are respectively connected to the signal input of the controller. When the controller receives the signal of the terminal pressure touch switch 64, the electromagnet 62 is controlled to generate magnetic attraction, so that the electromagnet 62 is attracted to the side guard plate 201. At this time, each high-pressure nozzle 55 is docked with each water injection port 205. And the rack 53 carries multiple high-pressure nozzles 55 and moves forward with the track. When the controller receives the signal of the head end pressure touch switch 63, the electromagnet 62 is controlled to disconnect the attraction of the side guard plate 201. At this time, the rack 53 carries all the high-pressure nozzles 55 to move backward under the elastic force of the thrust spring 69. After moving backward until the terminal pressure touch switch 64 has a trigger signal, each high-pressure nozzle 55 corresponds to each water injection port 205 of the latter group and moves back and forth in sequence.

[0043] like Figure 1 and Figure 5 As shown, flap assemblies 7 are respectively provided at the bottom of the front and rear side walls of the sludge bin 11. Fig. 9As shown, a flap assembly 7 includes a pin 70, a flap 71, a track plate 72, a track groove 73, a slider 74, a latch 75, an upper hinge seat 76, a lower hinge seat 77, a connecting rod 78 and a pressure rod 79. The flap 71 is hinged at the bottom of the front and rear side walls of the sludge bin 11 through the pin 70, and a pair of parallel track plates 72 are fixed on the front and rear side walls of the sludge bin 11, each track plate 72 is provided with a track groove 73, and a rack is provided on the outer side of each track groove 73. A slider 74 is set in each pair of track plates 72, and a pair of protruding latches 75 are respectively provided at the left and right ends of the slider 74. Each pair of latches 75 is supported in the track groove 73 and located in the groove of the corresponding rack. An inner spring is set in the inner cavity of the slider 74, and the inner spring is supported on the front and rear side walls of the sludge bin 11. Under the action of the inner spring, each latch 75 can be supported in the corresponding rack groove. A pressure rod 79 is fixed on the upper part of the slider 74 to facilitate the pressing operation. An upper hinge seat 76 is arranged on the lower side of the slider 74, and a lower hinge seat 77 is arranged on the back of the flap 71. A connecting rod 78 is hinged between the upper hinge seat 76 and the lower hinge seat 77. During operation, the pressure rod 79 is manually pressed to make each latch 75 disengage from the corresponding groove, and then the slider 74 is moved upward or downward, thereby driving the flap 71 to flip upward or downward. After releasing the hand, the inner spring supports the slider 74 to move outward, and the latches 75 at both ends of the slider 74 are clamped in the grooves of the rack, locking the slider 74 and the track plate 72 together to ensure that the flap 71 is at a fixed inclination angle. The flap 71 can move upward in a non-working state and is in an avoidance state. During the dredging construction process, the flap 71 is controlled to tilt downward, and the flap 71 is located below the liquid surface and above the silt layer, which can effectively prevent the turbid silt in the silt bin 11 from overflowing and polluting the river water source.

[0044] When the above equipment is in use, before entering the river channel, the equipment is in walking mode, the track extension plate 24 is laid flat, and the equipment quickly moves to the construction section. After arriving at the designated river section, the operator switches the equipment to dredging mode, at which time the track extension plate 24 is erected to prepare for the cleaning operation. First, place the nozzle of the equipment water supply pipe 32 below the water surface of the river channel, or connect the water supply nozzle to the spare water tank to ensure that the booster pump group 3 can continuously provide a high-pressure water source. Ensure that the suction pipe of the equipment is connected to the sludge truck box on the shore through a conveying pipeline to prepare for subsequent sludge extraction operations.

[0045] When performing dredging operations, after the equipment switches to the dredging mode, the extension plate 24 of the crawler is erected and enters the riverbed, and begins to move slowly along the bottom of the river. The extension plate 24 of the crawler can cut the surface of the silt and divide the silt into multiple cutting areas 29, ensuring that the silt can be effectively divided for subsequent processing. The crawler cutting method avoids silt agglomeration, ensures that the silt can be fully divided, and improves the dredging efficiency.

[0046] High-pressure water impact crushing: After the cutting area 29 is formed, the booster pump group 3 starts working, and the booster pump 31 provides high-pressure water flow, and the sludge in the cutting area 29 is crushed by high-pressure impact through the high-pressure nozzle 55. The crushing mechanism 5 automatically moves downward, accurately directing the crushing water flow to the cutting area 29, so that the sludge is effectively crushed. During the crushing process, the linkage mechanism 6 ensures that the high-pressure nozzle 55 moves synchronously with the side guard plate 201 to prevent the high-pressure water flow from impacting the expansion plate 24 or damaging the equipment, and at the same time ensures that the high-pressure nozzle 55 can continue to efficiently crush the sludge in the cutting area 29. The crushing operation of the high-pressure nozzle 55 ensures the thorough crushing of the sludge, and through the linkage mechanism, reduces the disturbance and pollution to the surrounding waters.

[0047] The suction pump 41 of the equipment starts working, and the crushed sludge is sucked into the bottom discharge pipe 45 through the suction nozzle 46. Subsequently, the sludge is transported to the sludge truck box on the shore through the suction main pipe 42 and the output pipe 47 for separation and treatment. The suction operation is carried out in a closed environment inside the equipment. The side guard plate 201 ensures that the high-pressure water flow and sludge will not leak into the river water body, avoiding secondary pollution during the operation. The fully enclosed suction process effectively reduces water source pollution and achieves efficient sludge extraction.

[0048] As the equipment moves forward, the high-pressure nozzle 55 in the crushing mechanism 5 moves with the crawler, continuously performing high-pressure water impact crushing and suction operations on the new cutting area 29, and the equipment can continue to move on its own above the riverbed silt layer to perform long-term, continuous dredging operations. The front and rear flap assemblies 7 of the silt bin 11 flip down during the dredging process and are located below the liquid surface to prevent the cleaned silt from leaking out, further reducing river pollution. The equipment can dredge while moving, with high operating efficiency, and at the same time use the flap assembly 7 to prevent turbid silt from overflowing, ensuring the river cleaning effect.

[0049] When the dredging work is completed, the equipment stops the booster pump 31 and the suction pump 41 to remove the residual silt inside. The flap assembly 7 returns to the upturned state to ensure that the equipment can be smoothly withdrawn from the river. The equipment switches to the walking mode again, the crawler extension plate 24 returns to the flat state, and the equipment smoothly returns to the shore from the riverbed. The equipment smoothly withdraws from the river channel and ends the operation, achieving efficient dredging and rapid evacuation.

[0050] The above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modification, equivalent substitution, improvement, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
