Description

Technical Field

[0001] This invention relates to the field of waste treatment technology, specifically to a device for clearing leachate grating plates in waste storage areas of waste-to-energy plants. Background Technology

[0002] Waste-to-energy incineration is currently one of the most practical and efficient methods for treating municipal solid waste, achieving waste reduction, resource recovery, and harmless treatment. Because municipal solid waste generally has a high moisture content, according to the design specifications for waste-to-energy incineration, waste must be stored in the waste storage area for at least 7 days before entering the incinerator. This allows for natural drainage and fermentation to reduce the moisture content and increase the calorific value of the waste, ensuring the stable and efficient operation of the waste-to-energy plant. The bottom of the waste storage area is typically equipped with leachate grating plates, whose core function is to intercept large pieces of waste plastics, debris, and other small particles, ensuring that the leachate flows smoothly into the collection channels. However, leachate itself is highly concentrated and viscous. In addition, debris in the garbage gets tangled and piled up, causing the leachate grid plate to become blocked. This makes it difficult for leachate to be discharged and causes it to accumulate at the bottom of the garbage bin, forming a phenomenon of "water-soaked garbage". This not only reduces the calorific value of the garbage and affects the stability of the incinerator's operation, but also leads to a series of problems such as low power generation, increased difficulty in flue gas treatment, and increased environmental protection costs. Therefore, a special unblocking device is urgently needed to solve this dilemma.

[0003] Currently, most waste-to-energy plants still rely on traditional manual methods to clear leachate grating blockages. Specifically, workers must enter the harsh environment of the waste storage area and manually clean the surface and pores of the grating with simple tools such as shovels and steel bars. While a few plants use simple rod-shaped unblocking structures to assist manual work, these structures lack a dedicated drive mechanism and are merely single rods. Essentially, they still rely on manual pushing and scraping of the rods, resulting in relatively outdated technology and a lack of targeted automation and mechanization.

[0004] Existing manual dredging methods and simple auxiliary structures have significant drawbacks. The most prominent problem is that sticky debris adheres to the surface of the dredging rods during the dredging process and is difficult to remove. Accumulated sticky debris not only leads to incomplete dredging of the grating mesh, with residual debris continuing to clog the channels and affect leachate flow, but it also causes the rod diameter to increase, eventually getting stuck in the grating mesh mesh and causing blockages. This severely impacts dredging efficiency and accelerates tool wear. Furthermore, manual dredging is inherently inefficient and labor-intensive, and the environment inside the waste bins is unpleasant, posing health and safety hazards, thus seriously restricting the quality and safety of dredging operations. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a dredging device for leachate grating plates in waste-to-energy plants. This device solves the problems of incomplete dredging and rod jamming caused by sticky waste adhering to the rods during the dredging of leachate grating plates in waste-to-energy plants, as well as the low efficiency and poor safety of manual dredging.

[0016] This invention provides a device for clearing leachate from a waste-to-energy plant's leachate grating. It offers the following advantages: 1. This invention utilizes a cam transmission structure driven by a second explosion-proof motor at the top of the dredging push rod. This structure drives the sleeve to slide back and forth along the outer side of the dredging push rod, and the telescopic rod to slide up and down, generating vibrations to dislodge attached garbage. Simultaneously, the first spring provides motion buffering, improving the problem of incomplete dredging and push rod jamming caused by garbage adhering to the push rod during the garbage dredging process. This enhances the cleanliness and efficiency of garbage dredging, while also improving the stability of equipment operation and reducing wear on the mechanism.

[0017] 2. This invention drives the rotating plate to rotate by starting the first explosion-proof motor in the base and driving the rotating shaft. Through the transmission of the connecting rod and the slider, the deflection plate and the support plate rotate and abut against the inner wall of the ditch. This improves the problem of low dredging accuracy and poor operational stability caused by displacement during the operation of the dredging device, and improves the fixed reliability of the dredging device and the accuracy of the dredging operation.

[0018] 3. This invention releases the lock on the unblocking push rod by pressing the pressing block inside the dustproof shell, causing the limiting block to deflect. After inserting the new push rod, the pressing block is released, and the second spring resets the limiting block to lock into the push rod groove. This improves the problems of cumbersome operation, low disassembly and assembly efficiency, and insufficient fixing reliability of unblocking push rod replacement and assembly, improves the convenience of disassembly and assembly and replacement efficiency of unblocking push rod, and enhances the connection stability after push rod installation.

[0021] The technical solutions in 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.

[0022] Please see the appendix Figure 1 -Appendix Figure 10This invention provides a dredging device for leachate grating in a waste-to-energy plant, comprising a base 1, a lower frame 2 fixedly connected to the top of the base 1, and a support component 3 fixedly connected to the top of the lower frame 2. The support component 3 is used to fix the dredging device entirely within the leachate channels of the waste storage tank. Specifically, the support component 3 is used to adapt to leachate channels of different widths, achieving precise fit and fixation with the channels by adjusting its own structure, preventing displacement of the device during dredging operations, and providing a stable installation support foundation for the upper structure of the device. A connecting plate 4 is installed on the top of the lower frame 2, which is used to connect the lower frame. The frame 2 and the upper frame 5 serve as a structural transition and load-bearing structure, transferring the supporting force of the lower frame 2 to the upper frame 5, while also providing an installation carrier for components such as the hydraulic pump station 15. A connecting seat 14 is fixedly connected to the top of the connecting plate 4, which is used to fix and install the hydraulic pump station 15, serving a connecting and load-bearing function. A lifting mechanism 18 is fixedly connected to the top of the connecting plate 4, and the upper frame 5 is internally threaded to the lifting mechanism 18. The upper frame 5 is used to install core working components such as the guide plate 11, guide rod 10, and hydraulic cylinder 13, providing a stable installation frame for the operation of the sliding and vibrating components 8 of the push rod 7, ensuring the coordinated operation of all components. The guide plate 11 is fixedly connected to the inner side of the upper frame 5. A slidable push rod 7 is slidably connected inside the guide plate 11. A vibration component 8 is installed on the top of the push rod 7. The vibration component 8 is used to vibrate and unclog the garbage on the grid plate. Specifically, it generates high-frequency vibrations that are transmitted to the push rod 7, and then to the grid plate and the clogged garbage, causing the clumps and sticky garbage to loosen and fall off. Combined with the pushing action of the push rod 7, it improves the unclogging effect and reduces the unclogging resistance. A hydraulic cylinder 13 is fixedly connected to the outside of the upper frame 5. A fixed seat 6 is fixedly connected to the output end of the hydraulic cylinder 13. A replacement component 9 is fixedly connected to the outside of the fixed seat 6. The replacement component 9 is used to replace the push rod 7 of different sizes for the grid plate. The lifting device is versatile. To ensure compatibility and avoid problems with ineffective dredging due to different grating sizes, the upper frame 5 is fixedly connected to the inner side of a guide rod 10. Simultaneously, the upper frame 5, via a lifting mechanism 18 on the connecting plate 4, utilizes the existing explosion-proof power supply box 19 to provide power, enabling the overall lifting of the upper frame 5 and all upper working structures. The lifting stroke adapts to gratings of existing heights, meeting the dredging operation requirements across the entire height range of the grating. A fixed seat 6 is slidably connected to the outer side of the guide rod 10. The guide rod 10 assists in guiding the sliding direction of the fixed seat 6, working in conjunction with the guide plate 11 to ensure smooth movement of the fixed seat 6 and the dredging push rod 7, preventing tilting, jamming, and other issues, thus ensuring smooth dredging operations. A Mecanum wheel 12 is rotatably connected to the outer side of the base 1, and a hydraulic pump station 15 is fixedly connected to the top of the connecting seat 14; an explosion-proof power supply box 19 is fixedly connected to the top of the connecting plate 4, thus providing a power source for the operation of the device; a camera 16 is fixedly connected to the top of the fixed seat 6, and a sensor 17 is fixedly connected to the top of the fixed seat 6. The sensor 17 is used to detect the thrust of the hydraulic cylinder, the extension and retraction length, and the operating status of the device, and transmits the detected signals to the operator, so that the operator can adjust the operating parameters according to the actual situation, ensuring that the dredging operation is efficient and safe, and at the same time, it can detect abnormal operation of the device in time to avoid equipment damage.

[0023] Please see the appendix Figure 2 -Appendix Figure 4 In a preferred embodiment of the present invention, the vibration assembly 8 includes a fixing plate 82, which is fixedly connected to the top of the unblocking push rod 7. The fixing plate 82 is used to fix and install the second explosion-proof motor 83, serving as a load-bearing and fixing function to ensure that the second explosion-proof motor 83 is firmly installed during vibration and to prevent loosening and falling off. The second explosion-proof motor 83 is fixedly connected to the outside of the fixing plate 82. The output end of the second explosion-proof motor 83 is fixedly connected to a second rotating shaft 84. Two cams 85 are fixedly connected to the outside of the second rotating shaft 84. A connecting plate 86 is rotatably connected to the outside of the two cams 85. The cams 85 adopt an eccentric structure design, which will generate eccentric vibration during rotation. At the same time, the two cams 85 are symmetrically arranged to ensure stable vibration direction and avoid unilateral vibration that causes the unblocking push rod 7 to tilt. The connecting plate 86 is used to convert the rotation of the cams 85 into the up-and-down reciprocating motion of the sleeve 81, transmitting the eccentric vibration of the cams 85 to the sleeve 81, and then to the unblocking push rod 7. The sleeve 81 is slidably connected to the outside of the unblocking push rod 7, and the sleeve 81 is used to wrap the top of the unblocking push rod 7. The sleeve 81 is equipped with a fixed block 87, a first spring 89, and a telescopic rod 88. The fixed block 87 is used to rotatably connect with the connecting plate 86, ensuring that the connecting plate 86 can drive the sleeve 81 to move smoothly. The fixed block 87 is fixedly connected to the inside of the sleeve 81, and the first spring 89 is installed inside the sleeve 81. The top of the unblocking push rod 7 is fixedly connected to the telescopic rod 88. One end of the first spring 89 is fixedly connected to the top of the unblocking push rod 7, and the other end of the first spring 89 is fixedly connected to the inside of the sleeve 81. 9 is used to buffer the up-and-down vibration of the sleeve 81 and assist the sleeve 81 in resetting, ensuring that the sleeve 81 can follow the rotation of the cam 85 to achieve stable up-and-down reciprocating vibration, thereby driving the unblocking push rod 7 to generate high-frequency vibration and improve the vibration unblocking effect; the other end of the connecting plate 86 is rotatably connected to the inside of the fixed block 87. The rotatable connection design between the connecting plate 86 and the fixed block 87 ensures that the cam 85 can smoothly drive the sleeve 81 to move up and down when it rotates, reducing motion resistance, avoiding jamming, and ensuring the stable operation of the vibration component 8.

[0024] Please see the appendix Figure 6 -Appendix Figure 8 In a preferred embodiment of the present invention, the support assembly 3 includes a first explosion-proof motor 31, which is fixedly connected inside the base 1. A first rotating shaft 32 is fixedly connected to the output end of the first explosion-proof motor 31. A rotating plate 33 is fixedly connected to the outer side of the first rotating shaft 32. Two first connecting rods 34 are rotatably connected to the outer side of the rotating plate 33. When the rotating plate 33 rotates under the drive of the first rotating shaft 32, it causes the two first connecting rods 34 to swing synchronously, thereby pushing the slider 35 to slide along the first fixed rod 37, thus realizing the structural adjustment of the support assembly 3. Two sliders 35 are rotatably connected to the outer side of the two first connecting rods 34. The slider 35 connects the first link 34 and the second link 38, converting the oscillation of the first link 34 into the oscillation of the second link 38. Simultaneously, when the slider 35 slides along the first fixed rod 37, it drives the second link 38 to move synchronously, thereby pushing the deflection plate 39 to deflect. Two second links 38 are rotatably connected to the outer sides of the two sliders 35, and two deflection plates 39 are rotatably connected to the outer sides of the two second links 38. The deflection plates 39 connect the second links 38 and the rotating rod 310, converting the oscillation of the second links 38 into the rotation of the rotating rod 310, thereby driving the support plate 311 to deflect, thus achieving the connection between the support plate 311 and the percolation filter. The leachate channel is fixedly fitted; two rotating rods 310 are fixedly connected inside the two deflecting plates 39. The rotating rods 310 are used to transmit the deflection force of the deflecting plates 39, driving the support plate 311 to deflect synchronously. The support plate 311 is used to fit against the inner wall or edge of the leachate channel, and the device is fixedly supported in the channel by friction, ensuring that the device is stable and does not move during operation; one end of the two rotating rods 310 passes through the lower frame 2 and is fixedly connected to the two support plates 311. A support block 36 is fixedly connected to the top of the lower frame 2, and a first fixing rod 37 is fixedly connected inside the support block 36; the slider 35 is slidably connected to the first fixing rod 37. On the outside, the support plate 311 is rotatably connected to the top of the lower frame 2. The rotatable connection design between the support plate 311 and the lower frame 2 allows the support plate 311 to flexibly deflect according to the channel size, ensuring that the support plate 311 can fit tightly with the channel and improve the support and fixation effect. The support plate 311 is a telescopic adjustment rod with a multi-stage telescopic structure. The extension length of the support plate 311 can be adjusted according to the width range of the leachate channel. After adjustment, it is fixed by locking bolts. In conjunction with the deflection structure of the original linkage drive of the support component 3, it can achieve fitting and fixation of channels with different widths, improving the adaptability of the device to channels with different working conditions.

[0025] Please see the appendix Figure 9 -Appendix Figure 10In a preferred embodiment of the present invention, the replacement component 9 includes a base plate 91, which is used to fix and install a dust cover 92, a support base 94, and a bracket 93, serving as a load-bearing and fixing element, and providing a stable installation foundation for the various components of the replacement component 9. The base plate 91 is fixedly connected to the outside of the fixing base 6, and the dust cover 92 is fixedly connected to the top of the base plate 91. The support base 94 is fixedly connected to the top of the base plate 91, and two second fixing rods 95 are fixedly connected inside the support base 94. Two limiting blocks 96 are rotatably connected to the outside of the two second fixing rods 95, and a second spring 97 is fixedly connected between the two limiting blocks 96. The limiting blocks 96 are used to engage in the grooves 98 on the outside of the unblocking push rod 7 to limit and fix the unblocking push rod 7, preventing it from falling off during operation. The two limiting blocks 96 are symmetrically arranged to ensure uniform fixing force on the unblocking push rod 7. The second spring 97 provides elastic force to the limiting blocks 96, pushing the two limiting blocks 96 to always remain engaged in the grooves 98, ensuring that the unblocking push rod 7 is securely engaged. The device is securely fixed. When replacing the unclogging push rod 7, pressing the pressing block 99 compresses the second spring 97, causing the limiting block 96 to disengage from the groove 98, facilitating quick removal of the old unclogging push rod 7. A bracket 93 is fixedly connected to the top of the base plate 91. A groove 98 is provided on the outer side of the unclogging push rod 7, and pressing blocks 99 are fixedly connected to the outer sides of the two limiting blocks 96. The pressing blocks 99 are used by the operator to press, causing the limiting blocks 96 to rotate around the second fixed rod 95, compressing the second spring 97, and causing the limiting blocks 96 to disengage from the groove 98. 8. Facilitates quick and easy replacement of the unblocking push rod 7, simplifying operation and reducing replacement difficulty; the unblocking push rod 7 is slidably connected inside the bracket 93, with the bottom of the unblocking push rod 7 contacting the top of the support base 94, the pressing block 99 is slidably connected inside the dustproof shell 92, and the outer side of the limiting block 96 is slidably connected inside the groove 98. The sliding connection design between the limiting block 96 and the groove 98 ensures that the limiting block 96 can smoothly enter and exit the groove 98, ensuring that the unblocking push rod 7 is firmly fixed and easy to replace, thus improving work efficiency.

[0026] Working Principle: When using this equipment, if the leachate grating in the waste bin is severely clogged, the unblocking device, driven by the Mecanum wheel 12 on the base 1, is first moved to a designated position through the channel via the remote control system. Then, the first explosion-proof motor 31 inside the base 1 is activated, driving the support assembly 3 inside the lower frame 2 to fix the unblocking device against the channel wall, preventing displacement during unblocking. Subsequently, the explosion-proof power box 19 increases power to drive the lifting mechanism 18, thereby moving the upper frame 5 to the height of the blockage. Then, the hydraulic pump station 15 fixed on the connecting plate 4 via the connecting seat 14 is activated, thereby driving the hydraulic cylinder 1 on the upper frame 5. The push rod on the 3 extends forward, causing the fixed seat 6 to slide forward on the guide rod 10. At the same time, the unblocking push rod 7 on the fixed seat 6 slides out through the guide plate 11. When the camera 16 and sensor 17 detect the grid plate, the unblocking push rod 7 is inserted into the hole on the leachate grid plate of the garbage bin to push away the blockage. Then, the vibration component 8 on the unblocking push rod 7 is activated, causing the attached garbage on the grid plate to vibrate and fall. At the same time, the unblocking push rod 7 is driven to reciprocate to unblock the grid plate, allowing the leachate in the garbage bin to flow out smoothly. When unblocking grid plates of different sizes, the replacement component 9 can be activated to disassemble and replace the unblocking push rod 7 of different sizes. When the unblocking device is fixed, the first explosion-proof motor 31 inside the base 1 is started to drive the first rotating shaft 32 and the rotating plate 33 to rotate, thereby causing the first connecting rod 34 on the rotating plate 33 to deflect synchronously. The slider 35 connected to the other end of the first connecting rod 34 slides on the first fixed rod 37 fixed on the support block 36, thereby causing the second connecting rod 38 rotating on the slider 35 and the deflection plate 39 to deflect. Finally, the support plate 311, which is coaxially fixed with the deflection plate 39 through the rotating rod 310, expands and contracts to a suitable length according to the width of the channel and then rotates, thereby pressing against the inner wall of the channel to prevent displacement during operation. When clearing the garbage, the second explosion-proof motor 83 on the fixed plate 82 at the top of the clearing push rod 7 is activated, which drives the second rotating shaft 84 and the cam 85 to rotate, thereby driving the connecting plate 86 and the fixed block 87 to move up and down synchronously, so that the sleeve 81 slides back and forth along the outside of the clearing push rod 7, and the telescopic rod 88 slides up and down, generating vibration and shaking off the garbage attachments. At the same time, the elastic potential energy of the first spring 89 has a buffering effect. When replacing different unclogging push rods 7, press the pressing block 99 that slides inside the dust cover 92. This causes the limiting blocks 96 on both sides to deflect outside the second fixing rod 95 on the support base 94. At this time, the second spring 97 is compressed, and the limiting block 96 deflects and slides out of the groove 98 on the outside of the unclogging push rod 7, releasing the lock. When installing a new unclogging push rod 7, press the pressing block 99 and insert the unclogging push rod 7 through the opening of the bracket 93 on the base plate 91, so that the bottom of the unclogging push rod 7 contacts the top of the support base 94. Then release the pressing block 99 so that the limiting block 96 slides into the groove 98. At the same time, the second spring 97 is in a tightened state, locking the unclogging push rod 7, completing the replacement.
