Description

Technical Field

[0001] This utility model relates to the field of sludge dewatering technology, specifically a device for dewatering and drying river and lake sludge. Background Technology

[0002] Silt has a very high water content and a large volume. It not only occupies the effective storage capacity of rivers and lakes, affecting flood control and drainage capacity and normal water flow, but may also release pollutants when environmental conditions change, damaging water quality and ecological balance. Existing filter press equipment is the conventional core equipment for solid-liquid separation. It applies pressure to the sludge through filter plate groups, causing water to be discharged through the filter holes of the screen plates, thus forming a solid filter cake and completing the preliminary treatment of sludge reduction. This type of equipment is widely used in industrial wastewater treatment and municipal sludge disposal. Its operating logic is based on static compression and screen plate filtration as the main processes. That is, it relies on the mechanical pressure between the filter plates to force free water and some bound water in the sludge to permeate through the screen plates, thereby achieving the separation of solid and liquid phases.

[0003] However, in actual filter press operations, as water continues to be filtered out through the screen plate and sludge gradually forms on the surface of the filter plate, under the influence of the squeezing force, some fine sludge particles tend to adhere tightly to the surface of the screen plate and the edges of the filter holes. In the solid-liquid separation stage of existing filter press equipment, the sludge that easily adheres to the screen plate can easily cause the filter holes of the screen plate to be gradually blocked by the adhered sludge, increasing the water penetration resistance in the subsequent filter press process and reducing the overall dewatering efficiency.

[0004] To address these issues, this invention provides a device for dewatering and drying river and lake silt. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dewatering and drying treatment device for river and lake sludge, which solves the problem mentioned above where, during the gradual formation of sludge on the filter plate surface, some fine sludge particles tend to adhere tightly to the surface of the screen plate and the edges of the filter holes due to the squeezing force. This addresses the issue of sludge easily adhering to the screen plate during the solid-liquid separation stage of existing filter press equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dewatering and drying device for river and lake silt, comprising: The equipment includes a support frame and an electric actuator movably connected to the support frame. A pressure plate, located on the same central axis as multiple sets of screen plates on the support frame, is fixedly connected to the electric actuator. It also includes, The screen disassembly mechanism is fixed at both ends of the equipment support, and the other end of the screen disassembly mechanism is movably connected to the screen plate. The screen dismantling mechanism includes bases fixed to both ends of the equipment support, and each base is equipped with an electric pusher cylinder. A connecting rod is movably connected to the output shaft of each electric pusher cylinder via a vibration mechanism. Both ends of each connecting rod are movably connected to a rocker arm, and the other end of each rocker arm is movably connected to a spring rod. The other end of each spring rod is movably connected to a support rod, and the other end of each support rod is fixedly connected to the base via a spring. Multiple sets of rotating rods are movably connected to the spring rods, and the other end of each rotating rod is rotatably connected to a rotating plate. The other end of each rotating plate is rotatably connected to one side of the screen plate via a rotating shaft, so that when the electric pusher rod drives the pressure plate... When the sludge inside the multiple sets of screen plates is squeezed into place, the electric push rod drives the pressure plate to reset. At the same time, the electric push cylinder is activated, which causes the output shaft of the electric push cylinder to push the connecting rod to move. The movement of the connecting rod drives the rocker arm and spring rod to move, which in turn causes the multiple sets of rotating rods on the spring rod to rotate. This rotating rod drives the rotating plate to rotate, thereby separating the multiple sets of screen plates. Under the reciprocating movement of the electric push cylinder, the multiple sets of screen plates are separated and shaken, thereby removing the sludge inside the multiple sets of screen plates and the sludge attached to the screen plates. After the sludge is removed, the output shaft of the electric push cylinder resets, and the equipment is reset under the action of the spring between the support rod and the base.

[0007] Preferably, the bottom of the equipment support is provided with a sludge cart for receiving dewatered sludge, and the side of the equipment support is provided with a water outlet and a sludge inlet, and both the water outlet and the sludge inlet are provided with check valves.

[0008] Preferably, the vibration mechanism includes a support plate connected to the output shaft of the electric push cylinder, and both the upper and lower ends of the support plate are fixedly connected to pull plates by elastic elements. The other side of the pull plate is movably connected to the connecting rod, so that when the electric push cylinder is started, the connecting rod is moved by the support plate and the pull plate.

[0009] Preferably, both elastic elements are provided with telescopic rods inside, and limit buttons are rotatably connected to them. The limit buttons are fixedly connected to the elastic elements, and the bottom of the telescopic rods is provided with threaded grooves. The limit buttons are provided with threads that match the threaded grooves inside, so that the elastic force of the elastic elements can be adjusted by rotating the limit buttons.

[0010] Preferably, a motor is fixedly connected to one side of the equipment support, and a turntable is fixedly connected to the output of the motor. A half-gear rod is movably connected to the outer circle of the turntable, and the middle end of the half-gear rod is movably connected to the equipment support. A vibrating hammer that meshes with the gear of the half-gear rod is movably connected to the equipment support, so that when the motor drives the turntable to rotate, it drives the half-gear rod to rotate around the outer circle of the turntable, thereby causing the gear on the half-gear rod to reciprocate and mesh with the upper tooth groove of the vibrating hammer, so that the vibrating hammer can reciprocate and hammer the pull plate and the support plate, thereby causing the connecting rod to reciprocate and move, and thus hammering the sludge attached to the screen plate.

[0011] This utility model provides a device for dewatering and drying river and lake silt. Compared with the prior art, it has the following advantages: (1) The dewatering and drying treatment device for river and lake sludge uses an electric pusher cylinder to drive the connecting rod to move, which in turn drives the rocker arm and spring rod to rotate the rotating plate around the rotating shaft, thereby separating multiple sets of screen plates. At the same time, the electric pusher cylinder moves back and forth to make the screen plates shake continuously, which can completely shake the dewatered sludge inside the screen plates and the sludge attached to the surface into the sludge cart. This process avoids the problem of sludge clogging the filter holes of the screen plates in traditional equipment, reduces water penetration resistance, ensures the filtration efficiency of the screen plates in each dewatering operation, and eliminates the need for manual cleaning of the screen plates, which greatly improves the continuity and overall efficiency of river and lake sludge dewatering treatment.

[0012] (2) The dewatering and drying treatment device for river and lake silt uses a motor to drive the turntable to rotate, which drives the half gear rod to swing back and forth. The vibrating hammer meshes with the half gear rod and repeatedly hammers the pull plate and support plate. The vibration force is transmitted to the screen plate through the connecting rod, which can remove fine sludge particles in the filter holes of the screen plate. At the same time, rotating the limit button can adjust the elastic force of the elastic element through the thread groove to change the vibration intensity. This design not only solves the problem that traditional equipment is difficult to clean the deep sludge attached to the screen plate, but also can adjust the vibration intensity according to the sludge moisture content and particle size, adapting to the treatment of river and lake silt under different working conditions, and ensuring that the equipment maintains a stable dewatering and drying capacity during long-term use.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] Please see Figures 1 to 5 A device for dewatering and drying river and lake silt, comprising: The equipment support 1 and the electric push rod 2 are movably connected to the equipment support 1. The electric push rod 2 is fixedly connected to a pressure plate 3 located on the same central axis as the multiple sets of screen plates 4 on the equipment support 1. It also includes, The screen disassembly mechanism 8 is fixed at both ends of the equipment support 1, and the other end of the screen disassembly mechanism 8 is movably connected to the screen plate 4. The screen dismantling mechanism 8 includes bases 81 fixed at both ends of the equipment support 1, and each base 81 is equipped with an electric pusher cylinder 82. A connecting rod 83 is movably connected to the output shaft of the electric pusher cylinder 82 via a vibrating mechanism 9. Both ends of the connecting rod 83 are movably connected to rocker arms 84, and the other end of the rocker arm 84 is movably connected to a spring rod 85. The other end of the spring rod 85 is movably connected to a support rod 86, and the other end of the support rod 86 is fixedly connected to the base 81 via a spring. Multiple sets of rotating rods 87 are movably connected to the spring rod 85, and the other end of the rotating rod 87 is rotatably connected to a rotating plate 88. The other end of the rotating plate 88 is rotatably connected to one side of the screen plate 4 via a rotating shaft 89. This allows the electric pusher cylinder 82 to reset the pressure plate 3 when the electric pusher cylinder 82 drives the pressure plate 3 to press the sludge inside the equipment support 1 of the multiple sets of screen plates 4 into place, and simultaneously the electric pusher cylinder 82... 2. Start-up causes the output shaft of the electric pusher cylinder 82 to push the connecting rod 83 to move. The movement of the connecting rod 83 drives the rocker arm 84 and the spring rod 85 to move, which in turn causes the multiple sets of rotating rods 87 on the spring rod 85 to rotate. This, in turn, drives the rotating plate 88 to rotate, thereby separating the multiple sets of screen plates 4. Under the reciprocating movement of the electric pusher cylinder 82, the multiple sets of screen plates 4 can be separated and shaken, thereby removing the sludge inside the multiple sets of screen plates 4 and the sludge attached to the screen plates 4. After the sludge is removed, the output shaft of the electric pusher cylinder 82 is reset. Under the action of the spring between the support rod 86 and the base 81, the equipment is reset. The bottom of the equipment support 1 is provided with a sludge cart 5 for receiving dewatered sludge. The side of the equipment support 1 is provided with a water outlet 6 and a sludge inlet 7, and both the water outlet 6 and the sludge inlet 7 are provided with check valves. During operation, river and lake silt is first injected into the equipment support 1 through the silt inlet 7. A check valve prevents silt backflow. The electric actuator 2 is activated, moving the pressure plate 3 towards the multiple sets of screen plates 4. The pressure plate 3 and screen plates 4 work together to apply pressure to the silt. Water in the silt seeps out through the filter holes of the screen plates 4 and is discharged through the outlet 6. The check valve prevents water backflow. Once the silt has been properly dehydrated, the electric actuator 2 resets the pressure plate 3. Simultaneously, the electric actuator cylinder 82 is activated. The output shaft of the electric actuator cylinder 82 pushes the connecting rod 83 to move. The connecting rod 83 drives the rocker arms 84 at both ends to swing, and the rocker arms 84 drive the spring rod 85 to move. Spring rod 85 drives multiple sets of rotating rods 87 to rotate. The rotating rods 87 pull rotating plate 88 to rotate around rotating shaft 89, thereby separating multiple sets of screen plates 4. Electric push cylinder 82 moves back and forth, causing screen plates 4 to continuously separate and shake, shaking off the dewatered sludge inside screen plates 4 and the sludge attached to the surface of screen plates 4. The sludge falls into the sludge cart 5 at the bottom of the equipment support 1 for collection. After the sludge is removed, the output shaft of electric push cylinder 82 resets, and the spring between support rod 86 and base 81 generates a rebound force, driving spring rod 85, rocker arm 84 and connecting rod 83 and other components to reset. Screen plates 4 return to their initial state, waiting for the next round of operation. Example

[0017] Please see Figures 1 to 5 This embodiment provides a technical solution based on Embodiment 1: The vibration mechanism 9 includes a support plate 91 connected to the output shaft of the electric push cylinder 82. Both the upper and lower ends of the support plate 91 are fixedly connected to pull plates 96 via elastic members 93. The other side of the pull plates 96 is movably connected to the connecting rod 83, so that when the electric push cylinder 82 starts, it drives the connecting rod 83 to move via the support plate 91 and pull plates 96. Each of the two elastic members 93 has a telescopic rod inside, and a limit button 94 is rotatably connected to its upper end. The limit button 94 is fixedly connected to the elastic member 93, and a threaded groove 95 is provided at the bottom of the telescopic rod. The limit button 94 has a thread matching the threaded groove 95 inside, so that the elastic member 93 can be adjusted by rotating the limit button 94. The elastic force of 3, a motor 92 is fixedly connected to one side of the equipment support 1, and a turntable 97 is fixedly connected to the output of the motor 92. A half gear rod 98 is movably connected to the outer circle of the turntable 97, and the middle end of the half gear rod 98 is movably connected to the equipment support 1. A vibrating hammer 99 that meshes with the gear of the half gear rod 98 is movably connected to the equipment support 1, so that when the motor 92 drives the turntable 97 to rotate, it drives the half gear rod 98 to rotate around the outer circle of the turntable 97, so that the gear on the half gear rod 98 reciprocates and meshes with the upper tooth groove of the vibrating hammer 99, so that the vibrating hammer 99 can reciprocate and hammer the pull plate 96 and the support plate 91, so that the connecting rod 83 can reciprocate and move, thereby hammering the sludge attached to the screen plate 4; During operation, the motor 92 is started synchronously during the operation of the screen dismantling mechanism 8. The motor 92 drives the turntable 97 to rotate, and the turntable 97 drives the half gear rod 98 to swing back and forth around its middle hinge point. The gear on the half gear rod 98 intermittently meshes with the tooth groove on the upper side of the vibrating hammer 99, causing the vibrating hammer 99 to move up and down reciprocally. The vibrating hammer 99 continuously strikes the pull plate 96 and the support plate 91. The pull plate 96 transmits the vibration force to the connecting rod 83, causing the connecting rod 83 to generate high-frequency reciprocating oscillation, which is then transmitted through the rocker arm. 84. Spring rod 85 and rotating rod 87 transmit the vibration to screen plate 4, enhancing the vibration effect of screen plate 4 and efficiently removing fine sludge particles attached to the surface of screen plate 4 and inside the filter holes. If the vibration intensity needs to be adjusted, the limit button 94 can be rotated. The limit button 94 adjusts the extension and retraction of the telescopic rod by threadedly engaging with the threaded groove 95 at the bottom of the telescopic rod, thereby changing the compression degree of the elastic element 93 and adjusting the elastic force of the elastic element 93 to adapt to the treatment needs of river and lake sludge with different water content and particle size.

[0018] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0019] Working principle: During operation, the silt to be treated is first fed into the equipment support 1 through the sludge inlet 7. The check valve of the sludge inlet 7 ensures that the silt enters smoothly and does not flow back. The electric push rod 2 is started, and the pressure plate 3 is driven by the electric push rod 2 to squeeze the silt between the screen plates 4 to achieve solid-liquid separation. The water is filtered out through the screen plates 4 and discharged from the outlet 6. After dewatering, the electric push rod 2 is reset, and the electric push cylinder 82 and the motor 92 are started synchronously. The screen disassembly mechanism 8 drives the screen plates 4 to separate and shake. The vibrating hammer 99 in the vibrating mechanism 9 hammers to generate high-frequency vibration, which thoroughly removes the sludge attached to the screen plates 4. The sludge falls to the sludge truck 5 for collection. After the operation is completed, all parts return to their initial state under the reset action of the spring and the electric push cylinder 82, completing a complete sludge dewatering and drying process.
