Description

Technical Field

[0001] This invention relates to the field of sludge dewatering equipment technology, specifically a resource-based treatment device for rapid dewatering of river sludge. Background Technology

[0002] With the acceleration of urbanization and increasingly stringent environmental protection requirements, river dredging has become an important part of water environment management. River silt, as a byproduct of water environment management, is characterized by high water content, high viscosity, and complex pollutant composition (such as heavy metals, organic matter, and pathogenic microorganisms). The flocculent and honeycomb structure of silt leads to the coexistence of free water and bound water, making it difficult for traditional dewatering technologies to efficiently separate the water. For example, naturally deposited silt has almost no strength; direct discharge can cause heavy metal migration due to leachate seepage, polluting soil and water bodies. Therefore, how to efficiently dewater silt and achieve its harmless, reduced-volume, and resource-based utilization (such as brick making, building material raw materials, roadbed filling, and landscaping soil) has become a key technical challenge in the current environmental protection and solid waste treatment fields.

[0003] Currently, common methods for dewatering sludge include natural drying, mechanical pressure filtration, and centrifugal dewatering.

[0004] 1. Although natural drying is low-cost, it depends on climate conditions, the dehydration cycle can take several weeks to months, and it requires a large area. Moreover, open-air operations can easily lead to the spread of pollutants, making it inefficient and unable to meet environmental protection requirements.

[0005] 2. Mechanical filter presses (including plate and frame filter presses and belt filter presses): While plate and frame filter presses can increase the solids content of the filter cake, they require a large space, necessitating a conditioning tank and screening system, resulting in a large footprint. They also require operating pressures exceeding 3 MPa, leading to high energy consumption. Furthermore, unloading necessitates manual cleaning of residual filter cake from the filter cloth, making continuous operation difficult. Belt filter presses, while allowing continuous feeding, have stringent requirements for sludge pretreatment. A certain proportion of composite flocculant must be added, and the filter belt tension must be precisely controlled; otherwise, the filter pores are easily clogged.

[0006] 3. Centrifugal dewatering technology is ineffective at separating fine-particle sludge because the fine particles are tightly bound to water molecules, making it difficult for centrifugal force to break down their colloidal structure. Furthermore, high rotational speeds easily lead to severe equipment wear, high maintenance costs, high energy consumption, and low economic efficiency.

[0007] For the reasons stated above, this application is hereby submitted. Summary of the Invention

[0008] In view of the above-mentioned shortcomings in the existing technology, the purpose of this invention is to provide a rapid dewatering device for river silt that can improve production efficiency and increase the silt dewatering rate.

[0009] The technical solution adopted by the present invention to achieve the above objectives is: a resource-based treatment device for rapid dewatering of river silt, comprising a silt storage tank, a silt conveying mechanism, a squeezing mechanism, and a power mechanism.

The driving roller and the driven roller are rotatably connected to the two sets of side guard plates, and the conveyor filter belt is located between the two sets of side guard plates.

[0016] A support frame is fixedly connected to a set of the side guard plates, and the top surface of the support frame abuts against the inner top surface of the conveyor filter belt.

[0017] In the above technical solution, in order to ensure that the dewatered mud cake is fully detached from the conveyor filter belt, a scraper is fixedly connected to the conveyor frame at the discharge end of the conveyor filter belt, and one end of the scraper abuts against the surface of the conveyor filter belt.

[0018] To prevent sludge from leaking out, an end baffle is fixedly connected to the conveyor frame at the feed end of the conveyor filter belt, and the bottom end of the end baffle abuts against the top surface of the conveyor filter belt.

[0019] In the above technical solution, in order to clean the surface of the conveyor filter belt and ensure excellent dewatering effect on the sludge, the following structure is also provided:

[0021] A first gear is fixedly connected to one end of the drive roller shaft, and a second gear is fixedly connected to one end of the cleaning roller shaft. The first gear and the second gear are meshed together.

[0022] In the above technical solution, the lifting module adopts the following structure:

[0023] The lifting module includes a module frame, a rotating disk, a traction arm, and a lifting arm. The module frame is fixedly connected to the side guard plate. The lifting arm is slidably connected to the module frame. The rotating disk is rotatably connected to the module frame. An eccentric shaft is fixedly connected to the rotating disk.

[0024] In the above technical solution, the extrusion component adopts the following structure:

[0025] The extrusion component includes an extrusion table, an extrusion frame, and a spring. The extrusion table is fixedly connected to the bottom end of the lifting arm. The extrusion frame is provided at the bottom of the extrusion table. The extrusion frame has a frame opening. The periphery of the extrusion table abuts against the edge of the frame opening. When the extrusion frame is located between the two sets of side guard plates, the outer wall of the extrusion frame abuts against the inner wall of the side guard plate.

[0026] Multiple sets of bottom lugs are fixedly connected to the edge of the extrusion frame. A sliding platform is fixedly connected to each set of bottom lugs on the extrusion platform. A set of sliding posts is fixedly connected to each set of bottom lugs. The sliding posts pass through the corresponding sliding platforms. A spring is fitted on each set of sliding posts. One end of the spring is fixedly connected to the bottom lug and the other end is fixedly connected to the sliding platform. A limit plate is fixedly connected to the upper part of the sliding platform.

[0027] In the above technical solution, the power mechanism includes a power unit, a first transmission component and a second transmission component, and the power output end of the power unit is fixedly connected to a power output main shaft;

[0028] The power output shaft is connected to the drive roller via the first transmission component;

[0029] The power output shaft is poweredly connected to the rotating disk through the second transmission component;

[0030] The first transmission component includes a first ratchet component, and the second transmission component includes a second ratchet component. Under the action of the first ratchet component and the second ratchet component, when the power device drives the drive roller to rotate, the rotating disk does not rotate, and when the power device drives the rotating disk to rotate, the drive roller does not rotate.

[0031] Furthermore, the first transmission component also includes a first power output shaft, a first transmission assembly, a first worm gear, and a first worm wheel.

[0034] Furthermore, the second transmission component also includes a second power output shaft, a second transmission component, a second worm gear, and a second worm wheel. One end of the power output shaft is poweredly connected to the second power output shaft, and the second power output shaft is provided with the second ratchet component.

[0035] A rotating shaft is fixedly connected to the rotating disk, and the rotating shaft is rotatably connected to the module frame. A second worm gear is fixedly connected to the rotating shaft, and a second worm is rotatably connected to the module frame. The second worm and the second worm gear are meshed together.

[0036] The second power output shaft and the second worm are connected by the second transmission component, which is located on the power output end side of the second ratchet component.

[0037] The beneficial effects of this invention are:

[0038] 1. The sludge in the sludge storage tank falls onto the conveyor belt under gravity. When the conveyor belt is driven by the power mechanism, the sludge can be transported to the bottom of the extrusion mechanism. After the conveyor belt has traveled a predetermined distance, the power mechanism drives the lifting module to work, so that the lifting module drives the extrusion component to extrude and dewater the sludge on the conveyor belt. The dewatered water can enter the water collection frame at the bottom. After the extrusion is completed, the power mechanism can drive the lifting module to work, so that the extrusion component moves away from the conveyor belt. Then the power device drives the conveyor belt to work again, so that the extruded mud cake is discharged from the discharge end, while the unextruded sludge is transported back to the bottom of the extrusion component. By repeating the above steps, the sludge can be dewatered, and a continuous cycle of sludge transportation, extrusion, and discharge can be realized, reducing manual intervention and improving processing efficiency.

[0039] 2. The conveyor filter belt includes a conveyor belt and a filter cloth belt on the outer surface of the conveyor belt. Furthermore, a support frame is also provided on the side guard plate to abut against the conveyor belt. In this way, when the extrusion component extrudes the sludge, the sludge can be dewatered through the filter cloth belt and the perforated conveyor belt. The support frame can also form an interaction force with the extrusion component, thereby ensuring a large extrusion force on the sludge and improving the sludge dewatering effect. Through the above structure, the sludge can be fully dewatered and has enhanced bearing capacity, ensuring the service life of the conveyor filter belt.

[0040] 3. The extrusion component includes an extrusion table and an extrusion frame located at the edge of the extrusion table. When the sludge is extruded by the extrusion component, the lifting module can drive the extrusion frame to descend, so that the extrusion frame covers the sludge on the conveyor filter belt. Then, under the action of the lifting module, the extrusion table can be driven to descend, so that the extrusion table can extrude the sludge in the extrusion frame. In this way, the extrusion frame descends first to form a closed space to prevent the sludge from overflowing laterally and to ensure pressure concentration. Then the extrusion table applies pressure. This step-by-step operation avoids the lateral diffusion of sludge and improves dewatering efficiency. Attached Figure Description

Detailed Implementation

[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] Example 1

[0058] Please see Figures 1-6 A resource-based treatment device for rapid dewatering of river silt includes a silt storage tank 100, a silt conveying mechanism 200, a squeezing mechanism 300, and a power mechanism 400. The silt storage tank 100 is used to store silt, and the silt storage tank 100 cooperates with the silt conveying mechanism 200 to convey the silt in the silt storage tank 100.

[0059] Specifically, the sludge conveying mechanism 200 includes a conveyor frame 201, a conveying filter belt 202, a drive roller 203, a driven roller 204, and a water collection frame 205. That is, the drive roller 203 and the driven roller 204 are rotatably connected to the conveyor frame 201, the conveying filter belt 202 is positioned between the drive roller 203 and the driven roller 204, and the water collection frame 205 is fixedly connected to the conveyor frame 201 between the drive roller 203 and the driven roller 204. The top surface of the water collection frame 205 corresponds to the top surface of the conveying filter belt 202. The power mechanism 400 is poweredly connected to the drive roller 203, enabling... The power mechanism 400 can provide power to the drive roller 203, causing the conveyor filter belt 202 to move. The sludge storage box 100 is fixedly connected to the conveyor frame 201, and the bottom of the sludge storage box 100 is provided with a sludge outlet pipe 101, which corresponds to the middle of the conveyor filter belt 202. A valve may or may not be provided on the sludge outlet pipe 101, depending on the actual situation. In this way, the sludge in the sludge storage box 100 can enter the conveyor filter belt 202 under the action of gravity. When the conveyor filter belt 202 moves, the sludge can be laid on the conveyor filter belt 202 and transported.

[0060] Furthermore, a squeezing mechanism 300 is provided on one side of the conveyor filter belt 202 on the conveyor frame 201. The squeezing mechanism 300 is used to squeeze and dewater the conveyed sludge. The squeezing mechanism 300 includes a lifting module 301 and a squeezing component 302 provided on the lifting module 301. The squeezing component 302 corresponds to the conveyor filter belt 202. The power mechanism 400 is poweredly connected to the lifting module 301, so that the lifting module 301 can be driven to work through the power mechanism 400, thereby enabling the squeezing component 302 to move up and down.

[0061] Furthermore, the conveyor belt 202 includes a conveyor belt 2021 and a filter cloth belt 2022. That is, the conveyor belt 2021 is provided with multiple sets of small holes 2023, and the conveyor belt 2021 is provided on the drive roller 203 and the driven roller 204. The filter cloth belt 2022 is fixedly connected to the outer surface of the conveyor belt 2021. In this way, the filter cloth belt 2022 and the perforated conveyor belt 2021 can realize the stable conveying of sludge and the dewatering of sludge. When the squeezing component 302 squeezes and dewaters the sludge, water can be discharged from the bottom of the conveyor belt 202 to the water collection frame 205, and the water is collected and discharged through the water collection frame 205.

[0062] In addition, the aforementioned conveyor frame 201 includes a support frame 2011 and two sets of side guard plates 2012 fixedly connected to the support frame 2011. The driving roller 203 and the driven roller 204 are rotatably connected to the two sets of side guard plates 2012. The conveyor filter belt 202 is located between the two sets of side guard plates 2012. At the same time, a bearing frame 2013 is also fixedly connected to one set of side guard plates 2012. The top surface of the bearing frame 2013 abuts against the inner top surface of the conveyor filter belt 202. In this way, the bearing frame 2013 can form an interaction force with the extrusion component 302, so as to avoid deformation of the conveyor filter belt 202 when the extrusion component 302 presses down, which would affect the dewatering effect of the sludge and easily cause damage to the conveyor filter belt 202.

[0063] Furthermore, in order to ensure that the dewatered mud cake is fully detached from the conveyor filter belt 202, a scraper 206 is fixedly connected to the conveyor frame 201 at the discharge end of the conveyor filter belt 202. One end of the scraper 206 is in contact with the surface of the conveyor filter belt 202. In this way, when the conveyor filter belt 202 moves the dewatered mud cake towards the discharge end, the scraper 206 can scrape the mud cake off the conveyor filter belt 202, preventing the mud cake from adhering.

[0064] Furthermore, an end baffle 207 is fixedly connected to the conveyor frame 201 at the feed end of the conveyor filter belt 202. The bottom end of the end baffle 207 abuts against the top surface of the conveyor filter belt 202. The end baffle 207 can block the sludge and prevent the sludge from leaking out from the feed end of the conveyor filter belt 202.

[0065] To further optimize the cleaning of the surface of the conveyor filter belt 202 and ensure excellent subsequent dewatering of sludge, a cleaning roller 208 is rotatably connected to the feed end of the conveyor frame 201 at the feed end of the conveyor filter belt 202. The cleaning roller 208 contacts the surface of the conveyor filter belt 202, and a first gear 209 is fixedly connected to one end of the drive roller 203. A second gear 210 is fixedly connected to one end of the cleaning roller 208. The first gear 209 and the second gear 210 mesh with each other. When the drive roller 203 rotates, the cleaning roller 208 can rotate under the action of the first gear 209 and the second gear 210. This allows the cleaning roller 208 to clean the surface of the conveyor filter belt 202, preventing sludge particles from clogging the filter cloth belt 2022 and affecting the subsequent sludge dewatering effect. Furthermore, the rotation direction of the cleaning roller 208 is opposite to the movement direction of the conveyor filter belt 202, which also improves the cleaning effect of the cleaning roller 208.

[0066] Example 2

[0067] Please see again Figures 7-9 A resource-based treatment device for rapid dewatering of river silt, based on Embodiment 1, provides a lifting module 301 with the following structure:

[0068] The lifting module 301 includes a module frame 3011, a rotating disk 3012, a traction arm 3013, and a lifting arm 3014. The module frame 3011 is fixedly connected to the side guard plate 2012. The lifting arm 3014 is slidably connected to the module frame 3011. The rotating disk 3012 is rotatably connected to the module frame 3011. An eccentric shaft 3015 is fixedly connected to the rotating disk 3012. The traction arm 3013 is rotatably connected to the eccentric shaft 3015. The other end of 013 is rotatably connected to the lifting arm 3014. The bottom end of the lifting arm 3014 is fixedly connected to the extrusion component 302. The power mechanism 400 is powered to the rotating disk 3012. Thus, the power mechanism 400 can drive the rotating disk 3012 to rotate. Then, under the action of the traction arm 3013, the lifting arm 3014 can move up and down on the module frame 3011, thereby causing the extrusion component 302 at the bottom to move up and down.

[0069] To improve the uniformity of the downward pressure of the extrusion component 302, the aforementioned rotating disk 3012 and the cooperating traction arm 3013, lifting arm 3014 and other components are all in two sets.

[0070] This embodiment also provides an extrusion component 302 as follows:

[0071] In this embodiment, the extrusion component 302 includes an extrusion table 3021, an extrusion frame 3022, and a spring 3023. Specifically, the bottom end of the lifting arm 3014 is fixedly connected to the extrusion table 3021, the bottom of the extrusion table 3021 is provided with an extrusion frame 3022, the extrusion frame 3022 is provided with a frame opening, the periphery of the extrusion table 3021 abuts against the edge of the frame opening, and when the extrusion frame 3022 is located between the two sets of side guard plates 2012, the outer wall of the extrusion frame 3022 abuts against the inner wall of the side guard plate 2012.

[0072] Furthermore, multiple sets of bottom lugs 3024 are fixedly connected to the edge of the extrusion frame 3022. A sliding table 3025 is fixedly connected to each set of bottom lugs 3024 on the extrusion table 3021. A set of sliding posts 3026 is fixedly connected to each set of bottom lugs 3024. The sliding posts 3026 pass through the corresponding sliding table 3025. A spring 3023 is fitted on each set of sliding posts 3026. One end of the spring 3023 is fixedly connected to the bottom lug 3024, and the other end is fixedly connected to the sliding table 3025. A limit plate 3028 is fixedly connected to the upper part of the sliding table 3025.

[0073] When the lifting arm 3014 descends, the squeezing frame 3022 and the squeezing table 3021 descend first. At this time, the sludge conveyed by the conveyor belt 202 is covered by the squeezing frame 3022. When the lifting arm 3014 continues to descend, the squeezing frame 3022 does not descend. Under the action of the spring 3023, the squeezing table 3021 continues to descend. In this way, the squeezing table 3021 can press down the sludge in the squeezing frame 3022. Combined with the conveyor belt 202, the sludge can be dewatered. The squeezing frame 3022 descends first to form a closed space to prevent the sludge from overflowing laterally and to ensure pressure concentration. Then the squeezing table 3021 applies pressure. This step-by-step operation avoids the lateral diffusion of sludge and improves the dewatering efficiency.

[0074] Furthermore, multiple sets of guide columns 3027 are fixedly connected to the extrusion table 3021. The guide columns 3027 are slidably connected to the module frame 3011, thereby improving the stability of the extrusion table 3021 during descent.

[0075] Example 3

[0076] Please see again Figure 10 , Figure 11 A resource-based treatment device for rapid dewatering of river silt, based on embodiment 2, further describes the power mechanism 400 as including a power unit 401, a first transmission component 402 and a second transmission component 403, wherein the power output end of the power unit 401 is fixedly connected to a power output shaft 4011.

[0077] The power output shaft 4011 is poweredly connected to the drive roller 203 through the first transmission component 402. That is, the first transmission component includes a first ratchet component 4021, a first power output shaft 4022, a first transmission assembly 4023, a first worm 4024, and a first worm wheel 4025. One end of the power output shaft 4011 is poweredly connected to the first power output shaft 4022, and the first power output shaft 4022 is provided with the first ratchet component 4021. In addition, the first worm wheel 4025 is fixedly connected to one end of the roller shaft of the drive roller 203, and the first worm 4024 is rotatably connected to the side guard plate 2012. The first worm 4024 and the first worm wheel 4025 are meshed and connected. The first power output shaft 4022 and the first worm 4024 are poweredly connected through the first transmission assembly 4023, and the first transmission assembly is located on the power output end side of the first ratchet component 4021.

[0078] Furthermore, the power output main shaft 4011 is poweredly connected to the rotating disk 3012 via the second transmission component 403. The second transmission component 4033 includes a second ratchet component 4031, a second power output shaft 4032, a second transmission component 4033, a second worm gear 4034, and a second worm wheel 4035. That is, one end of the power output main shaft 4011 is poweredly connected to the second power output shaft 4032, and the second power output shaft 4032 is provided with the second ratchet component 4031. In addition, a rotating shaft is fixedly connected to the rotating disk 3012, and the rotating shaft is rotatably connected to the module frame 3011. A second worm gear 4035 is fixedly connected to the shaft, and a second worm 4034 is rotatably connected to the module frame 3011. The second worm 4034 and the second worm gear 4035 are meshed together. When a structure of two sets of rotating disks 3012 is adopted, two sets of second worm gears 4034 and second worm gears 4035 can be set as above. The two sets of second worm gears 4034 are fixedly connected. Furthermore, the second power output shaft 4032 and the second worm gear 4034 are connected by a second transmission component 4033. The second transmission component 4033 is located on the power output end side of the second ratchet component 4031.

[0079] The first ratchet component 4021 and the second ratchet component 4031 mentioned above are both prior art, so they will not be described in detail here. The first transmission component 4023 and the second transmission component can be a combination of pulley and belt or a combination of sprocket and chain, or any structure with transmission effect can be used.

[0080] Under the action of the first ratchet component 4021 and the second ratchet component 4031, when the power device 401 drives the drive roller 203 to rotate, the rotating disk 3012 does not rotate, and when the power device 401 drives the rotating disk 3012 to rotate, the drive roller 203 does not rotate. Specifically, when the power device 401 needs to drive the drive roller 203 to rotate, the power device 401 can drive the power output shaft 4011 to rotate in the forward direction. At this time, the power is transmitted to the first power input shaft. Under the action of the first ratchet component 4021 (the pawl can push the ratchet disk to rotate), the power is transmitted to the first transmission component 4023. The first transmission component 4023 transmits the power to the first worm gear 4024. The first worm gear 4024 drives the first worm wheel 4025 to rotate, which finally causes the drive roller 203 to rotate and the filter belt 202 to work. At the same time, the cleaning roller 208 can also rotate to achieve the cleaning work of the filter belt 202.

[0081] At this time, the power can also be transmitted to the second power input shaft. Under the action of the second ratchet component 4031 (the pawl cannot push the ratchet disk to rotate), the power cannot be transmitted to the second transmission component 4033, which means that the power cannot reach the rotating disk 3012. At this time, the lifting module 301 does not work and therefore does not perform the squeezing and dehydration work.

[0082] When the power unit 401 needs to drive the rotating disk 3012 to rotate, the power unit 401 can drive the power output shaft 4011 to rotate in the opposite direction. At this time, the power is transmitted to the second power input shaft. Under the action of the second ratchet component 4031 (the pawl can push the ratchet disk to rotate), the power is transmitted to the second transmission component. The second transmission component then transmits the power to the second worm 4034. The second worm 4034 drives the second worm wheel 4035 to rotate, which finally causes the rotating disk 3012 to rotate. When the rotating disk 3012 rotates completely, the extrusion component 302 can realize one lifting and lowering reciprocating action to realize the extrusion and dewatering of sludge.

[0083] At this time, the power can still be transmitted to the first power input shaft. Under the action of the first ratchet component 4021 (the pawl cannot push the ratchet disc to rotate), the power cannot be transmitted to the first transmission component 4023, which means that the power cannot reach the drive roller 203. At this time, the conveyor belt 202 does not move, and therefore does not convey the sludge.

[0084] With the aforementioned power mechanism 400, the required drive source can be greatly reduced while meeting the normal operating requirements of the equipment, thereby resulting in a low overall failure rate and easy maintenance and repair.

[0085] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0086] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
