Abstract
Description
Technical Field
[0001] This invention relates to the field of waste treatment and environmental protection equipment, and in particular to a high-viscosity waste sludge conveying device for furnace feeding. Background Technology
[0002] With the acceleration of urbanization, the amount of sludge generated from municipal solid waste and sewage treatment has increased dramatically. Waste-to-energy incineration is widely used as an effective method for waste reduction and resource recovery. Before waste and sludge (often mixed) are fed into the furnace, a suspended conveyor system is usually used to transport the material from the storage area to the incinerator's feed hopper. However, highly viscous waste sludge, due to its high water content and strong adhesion, easily forms bridging and sticking to the walls of the feed hopper, causing material blockage and preventing it from falling smoothly into the furnace.
[0003] To address the aforementioned clogging issues, existing technologies involve installing active or passive arch-breaking devices within the hopper. For example, a common solution is to install an arch-breaking screw or rotating blade driven by an independent motor within the hopper, which continuously rotates and agitates the material to break up bridging. However, these solutions require additional motors, reducers, and control systems, increasing equipment investment and energy consumption. Furthermore, in the high-temperature, high-humidity, and highly corrosive environment of waste incineration, the failure rate of motors and electrical components is high, making maintenance difficult. Another approach is to use a pneumatic or hydraulically driven hammer device to strike the hopper wall from the outside, using vibration to cause the material to fall. However, this method has limited effectiveness in breaking up highly viscous materials, and continuous hammering generates significant noise and causes fatigue damage to the hopper structure.
[0004] Therefore, how to effectively and reliably break up high-viscosity waste sludge in the hopper without requiring an additional independent power source or significantly increasing equipment complexity is a major technical problem that urgently needs to be solved in this field. Summary of the Invention
[0005] To address the aforementioned technical problems, this invention provides a high-viscosity waste sludge conveying device for furnace feeding.
[0006] This application provides a high-viscosity waste sludge conveying device for furnace operation, comprising: An intelligent overhead conveyor system includes a circular track, a conveyor chain traveling along the circular track, and overhead scraper assemblies spaced along the conveyor chain; an arch-breaking hopper located at the lower output end of the circular track, comprising a hopper shell, an active arch-breaking screw arranged transversely at the lower part of the hopper shell, and a driven bevel gear coaxially fixedly connected to the active arch-breaking screw; and at least one set of trigger-type transmission components fixedly installed in a specific section of the circular track, including an active bevel gear meshing with the driven bevel gear, a vertical transmission screw coaxially fixed with the active bevel gear, and a lifting nut slider sleeved on the vertical transmission screw; when the overhead scraper assembly moves with the conveyor chain to the position of the trigger-type transmission components, it pushes the lifting nut slider upward along the vertical transmission screw, thereby driving the active bevel gear to rotate, and driving the driven bevel gear and the active arch-breaking screw to rotate.
[0007] By adopting the above technical solution, this device utilizes the existing suspended scraper assembly in the intelligent suspended conveyor system as a power source. When they pass through a specific position, they trigger and drive the arch-breaking screw to rotate through mechanical contact. This eliminates the need for a separate motor for the arch-breaking screw, saving energy and cost. Simultaneously, the intermittent movement of the conveyor chain achieves intermittent drive of the arch-breaking screw, effectively breaking up material bridging within the hopper while avoiding excessive agitation. The specific operation process is as follows: the conveyor chain drives the suspended scraper assembly to circulate along the circular track. When it reaches the section equipped with the trigger-type transmission assembly, the suspended scraper assembly contacts the lifting nut slider and pushes it upwards along the vertical transmission screw, thereby driving the active bevel gear to rotate. The active bevel gear drives the meshing driven bevel gear and the active arch-breaking screw to rotate. The rotation of the active arch-breaking screw agitates the sludge at the bottom of the hopper, breaking up the bridging structure and promoting material descent.
[0008] Preferably, the suspended scraper assembly includes: a scraper bracket, the top of which is hinged to the conveyor chain; a V-shaped scraper plate, fixed to the lower end of the scraper bracket, for supporting and pushing sludge; and an actuating protrusion disposed on the side of the scraper bracket, the front end of which is provided with a rolling bearing; the lifting nut slider is provided with a vertical actuating plate, the upper end of which is provided with a wedge-shaped guide surface that cooperates with the rolling bearing; when the rolling bearing rolls along the wedge-shaped guide surface, the lifting nut slider is pushed upward.
[0009] By adopting the above technical solution, the triggering and mating structure is specified. The cooperation between the rolling bearing and the wedge-shaped guide surface transforms horizontal motion into vertical motion. Rolling friction greatly reduces contact resistance, making the triggering process smoother and more reliable, and reducing the risk of wear and jamming. The V-shaped scraper can more effectively support and push highly viscous sludge, preventing it from slipping during conveying. The specific operating procedure is as follows: when the scraper support moves with the conveyor chain, the rolling bearing at the front end of the actuating protrusion on its side first contacts the wedge-shaped guide surface at the upper end of the vertical scraper. As the scraper continues to move forward, the rolling bearing rolls upward along the wedge-shaped guide surface, thereby smoothly lifting the vertical scraper together with the lifting nut slider.
[0010] Preferably, it also includes a linkage enhancement mechanism, which includes: an eccentric mass block fixed on the outer circumference of the active arch-breaking screw; and multiple elastic impact plates disposed on the inner wall of the hopper shell; when the active arch-breaking screw rotates, the eccentric mass block generates periodic centrifugal force, causing the active arch-breaking screw to generate radial micro-vibration, which is transmitted to the elastic impact plates through the hopper shell, causing the elastic impact plates to generate high-frequency knocking on the sludge adhering to the inner wall of the hopper.
[0011] By adopting the above technical solution, the active arch-breaking screw vibrates its eccentric mass block while rotating to break up arches. This vibration is transmitted to the elastic impact plate, forming a continuous high-frequency impact on the inner wall of the hopper, effectively removing the sludge adhering to the inner wall. This achieves "multi-purpose use," solving the two technical problems of screw arch breaking and sludge adhesion to the hopper wall simultaneously without adding an additional power source. The specific operation process is as follows: When the active arch-breaking screw rotates, it drives the eccentric mass block to rotate around its axis, generating periodic centrifugal force, which causes the screw to produce slight radial vibration. This vibration is transmitted to the hopper shell through the screw bearing seat. The hopper shell then transmits the vibration to the elastic impact plate on the inner wall, which vibrates at high frequency and repeatedly impacts the inner wall of the hopper, causing the adhered sludge to fall off.
[0012] Preferably, the thread helix angle of the active arch-breaking screw is 15° to 25°, and the thread crest is provided with a serrated cutter; the transmission ratio between the driven bevel gear and the active bevel gear is 1:2 to 1:4, so that the active arch-breaking screw rotates 1.5 to 2.5 revolutions each time the suspension scraper assembly is triggered.
[0013] By adopting the above technical solution, the screw parameters and transmission ratio are defined. A specific helix angle, combined with a serrated cutter, can more effectively cut and tear highly viscous sludge, preventing material from entangled on the screw. The optimized transmission ratio ensures that each trigger action causes the screw to rotate a sufficient number of revolutions to produce effective arch breaking and vibration effects, while avoiding energy waste or excessive material compaction due to excessive rotation. The specific operating procedure is as follows: each time the suspended scraper assembly is triggered, the active arch-breaking screw rotates 1.5-2.5 revolutions, its serrated cutter cuts the material, and the screw thread pushes the material downwards.
[0014] Preferably, the trigger-type transmission assembly further includes a reset spring, which is sleeved on the vertical transmission screw and located between the lifting nut slider and the driving bevel gear, and is used to automatically lower and reset the lifting nut slider after the suspension scraper assembly leaves; a ball screw pair structure is provided between the vertical transmission screw and the lifting nut slider.
[0015] By adopting the above technical solution, the return spring ensures that the lifting nut slider can quickly and reliably reset after triggering, preparing for the next trigger. The ball screw pair structure transforms the sliding friction between the lifting nut slider and the vertical transmission screw into rolling friction, greatly improving transmission efficiency. This allows the screw to be driven sensitively even when the slider is subjected to large forces, while reducing wear. The specific operation process is as follows: the suspended scraper assembly pushes the slider upward and compresses the spring, while simultaneously driving the screw to rotate; when the scraper assembly is removed, the spring force pushes the slider downward to reset. Under the action of the ball screw pair, the slider descent process is also efficient and smooth.
[0016] Preferably, the intelligent suspended conveying system further includes: multiple position sensors arranged along the circular track; a controller connected to the position sensor signals; and a frequency converter installed on the conveyor chain drive motor; the controller controls the conveying speed of the suspended scraper assembly when passing the trigger-type transmission assembly according to the material level signal in the hopper shell, thereby adjusting the intermittent rotation frequency of the active arch-breaking screw.
[0017] By adopting the above technical solution, intelligent closed-loop control is introduced. The controller can automatically adjust the running speed of the conveyor chain according to the real-time material level in the hopper, thereby changing the frequency at which the scraper assembly triggers the anti-bridging screw. When the material level is high and the risk of blockage is high, the frequency is increased to strengthen anti-bridging; when the material level is low, the frequency is decreased to avoid unnecessary energy consumption and component wear. This achieves on-demand adjustment of anti-bridging intensity, improving the automation level and energy efficiency of the device. The specific operation process is as follows: the position sensor detects the position of the suspended scraper assembly, the material level sensor detects the material height in the hopper, the controller receives these signals, and adjusts the speed of the conveyor chain drive motor through the frequency converter driver according to the preset logic. When the material level is high, the controller increases the conveyor chain speed, causing the scraper assembly to pass through the trigger zone more frequently, thereby driving the anti-bridging screw to rotate and vibrate at a higher frequency; conversely, the speed is reduced.
[0018] In summary, the present invention has at least the following beneficial effects: Because this invention uses a trigger-type transmission component, the movement of the suspension scraper assembly of the suspension conveying system itself is used as a power source to drive the active arch-breaking screw in the hopper to rotate, thus achieving the effect of no need for additional motor configuration, compact structure, energy saving and consumption reduction, and effective arch breaking by utilizing the intermittent movement of the conveyor chain.
[0019] In this invention, a linkage-enhancing mechanism is preferably adopted. An eccentric mass block is set on the active arch-breaking screw and combined with the elastic impact plate on the inner wall of the hopper. As the screw rotates, the vibration energy generated by the eccentric mass block is transmitted to the elastic impact plate, causing it to strike the inner wall of the hopper at a high frequency. This achieves the effect of automatically removing the material adhering to the inner wall while breaking the arch, realizing multiple uses of one machine, and further improving the smoothness of material conveying.
[0020] The present invention preferably employs an intelligent control system consisting of a position sensor, a controller, and a frequency converter. Because it can automatically adjust the conveyor chain speed based on the real-time material level in the hopper, and thus adjust the triggering frequency of the anti-bridging screw, it achieves the effects of on-demand adjustment of anti-bridging strength, high automation, and optimized energy efficiency.

[0025] The present invention will be further described in detail below with reference to all the accompanying drawings.
[0026] Example 1
[0027] This embodiment discloses a high-viscosity waste sludge feeding and conveying device, including an intelligent suspended conveying system 1, an arch-breaking hopper 2, and a set of trigger-type transmission components 3.
[0028] Reference Figure 1 , Figure 2 and Figure 3 The intelligent overhead conveying system 1 includes a closed circular track 11, a conveyor chain 12 traveling along the circular track 11, and multiple overhead scraper assemblies 13 spaced apart on the conveyor chain 12. The overhead scraper assemblies 13 are used to support and convey highly viscous waste sludge. An arch-breaking hopper 2 is located at the lower output end of the circular track 11 to receive the sludge unloaded from the overhead scraper assemblies 13 and guide it to the downstream incinerator feed inlet. The arch-breaking hopper 2 specifically includes a hopper shell 21 that is wider at the top and narrower at the bottom, an active arch-breaking screw 22 horizontally arranged above the lower discharge port of the hopper shell 21, and a driven bevel gear 23 coaxially fixedly connected to one end of the active arch-breaking screw 22. The function of the active arch-breaking screw 22 is to agitate, cut, and push the material, preventing it from bridging and clogging at the hopper outlet.
[0029] Reference Figure 1 , Figure 2 and Figure 3The trigger-type transmission assembly 3 is fixedly installed in a specific section of the annular track 11, located directly above or near the arch-breaking hopper 2, allowing the suspended scraper assembly 13 passing through this section to interact with the trigger-type transmission assembly 3. The trigger-type transmission assembly 3 includes a driving bevel gear 31, a vertical transmission screw 32, and a lifting nut slider 33. The driving bevel gear 31 meshes with the driven bevel gear 23 on the arch-breaking hopper 2. The lower end of the vertical transmission screw 32 is coaxially and fixedly connected to the driving bevel gear 31, while its upper end is mounted on a bracket of the annular track 11 via a bearing seat, allowing it to rotate freely. The lifting nut slider 33 is sleeved on the vertical transmission screw 32, with its internal thread engaging with the external thread of the vertical transmission screw 32.
[0030] The implementation principle of this embodiment is as follows: The conveyor chain 12 runs cyclically along the circular track 11 under the drive of the drive motor, and the suspended scraper assembly 13 carries the sludge from upstream to above the arch-breaking hopper 2. When the suspended scraper assembly 13 continues to move forward and reaches the position where the trigger-type transmission assembly 3 is installed, its lower end or side will contact the lifting nut slider 33 and generate relative movement. Since the movement direction of the suspended scraper assembly 13 is horizontal, while the lifting nut slider 33 is limited by the guide structure and can only move up and down, the horizontal movement of the suspended scraper assembly 13 will push the lifting nut slider 33 to slide upward along the vertical transmission screw 32. The rise of the lifting nut slider 33 will drive the vertical transmission screw 32 to rotate, and the vertical transmission screw 32 will drive the coaxial active bevel gear 31 to rotate. The active bevel gear 31 will then drive the driven bevel gear 23 to rotate, and finally drive the active arch-breaking screw 22 to rotate. The rotation of the active arch-breaking screw 22 agitates the highly viscous sludge accumulated in the hopper, destroys the bridging structure, and allows it to fall smoothly. After the suspended scraper assembly 13 passes the trigger position, the lifting nut slider 33 can descend and reset along the vertical transmission screw 32 under its own weight or the action of the reset device, waiting for the next trigger.
[0031] Reference Figure 1 , Figure 2 and Figure 3The suspended scraper assembly 13 includes a scraper bracket 131, a V-shaped scraper 132, and a lever 133. The top of the scraper bracket 131 is hinged to the conveyor chain 12, allowing it to remain vertically downward during operation. The V-shaped scraper 132 is fixed to the lower end of the scraper bracket 131, with its V-shaped opening facing upward, to more stably support highly viscous sludge and prevent it from dripping or slipping during transport. The lever 133 is located on the side of the scraper bracket 131, with a rolling bearing 134 mounted at its front end. Correspondingly, a vertical lever 331 is fixedly mounted on the lifting nut slider 33. The upper surface of the vertical lever 331 is machined into a wedge-shaped guide surface 332, with the lower end of the wedge-shaped guide surface 332 facing the direction of the suspended scraper assembly 13. The rolling bearing 134 cooperates with the wedge-shaped guide surface 332.
[0032] The implementation principle of this embodiment is as follows: When the suspended scraper assembly 13 moves to the triggering area along with the conveyor chain 12, the rolling bearing 134 on its side first contacts the wedge-shaped guide surface 332 at the upper end of the vertical guide plate 331. As the scraper assembly continues to move horizontally forward, the rolling bearing 134 rolls upward along the wedge-shaped guide surface 332, converting the horizontal motion into the vertical upward motion of the vertical guide plate 331, thereby smoothly and effortlessly pushing the lifting nut slider 33 upward. Rolling friction replaces sliding friction, significantly reducing triggering resistance and making the action smoother and more reliable. The design of the V-shaped scraper 132 also enhances the load-bearing capacity for highly viscous materials during the conveying process.
[0033] Reference Figure 1 , Figure 2 and Figure 3 The trigger-type transmission assembly 3 also includes a return spring 34. This return spring 34 is sleeved on the vertical transmission screw 32 and located between the lifting nut slider 33 and the driving bevel gear 31. Simultaneously, the cooperation between the vertical transmission screw 32 and the lifting nut slider 33 adopts a ball screw pair structure, that is, circulating balls are provided between the screw and the nut, converting sliding friction into rolling friction.
[0034] When the suspended scraper assembly 13 pushes the lifting nut slider 33 upward, the return spring 34 is compressed. After the suspended scraper assembly 13 moves away, the spring force of the return spring 34 pushes the lifting nut slider 33 downward quickly and reliably, ensuring that the transmission assembly can quickly return to the ready-to-trigger state, preparing for the next trigger. The ball screw pair structure greatly reduces the frictional resistance between the lifting nut slider 33 and the vertical transmission screw 32, allowing the slider to sensitively drive the screw rotation even under small thrust. Furthermore, the slider descends more smoothly under the action of the return spring, improving the efficiency and response speed of the entire transmission chain and reducing wear.
[0035] Reference Figure 1 , Figure 2 and Figure 3 The linkage enhancement mechanism 4 includes an eccentric mass block 41 and elastic impact plates 42. The eccentric mass block 41 is fixed on the outer circumference of the active arch-breaking screw 22, that is, its center of mass is not on the rotation axis of the screw. Multiple elastic impact plates 42 are installed on the inner wall of the hopper shell 21 through spring hinges or elastic sheets, with their free ends facing the center of the hopper.
[0036] Reference Figure 1 , Figure 2 and Figure 3 The intelligent overhead conveyor system 1 also includes multiple position sensors 14 and a controller 15. Position sensors 14 (such as proximity switches) are arranged along the circular track 11, with at least one installed at the inlet of the trigger-type drive assembly 3 to detect the position of the overhead scraper assembly 13. The controller 15 (such as a PLC) is signal-connected to the position sensors 14. A frequency converter 16 is mounted on the drive motor of the conveyor chain 12 and signal-connected to the controller 15. A level sensor (such as a rotary paddle or ultrasonic type) is also provided inside the hopper housing 21 to detect the height of the material inside; this level sensor is also signal-connected to the controller 15.
[0037] Reference Figure 1 , Figure 2 and Figure 3 When the active arch-breaking screw 22 rotates, it drives the eccentric mass block 41 to rotate synchronously, generating periodic centrifugal force, which forces the screw itself to produce radial micro-vibration. This vibration is transmitted to the hopper housing 21 through the bearing seat supporting the screw, and the hopper housing 21 then transmits the vibration to the elastic impact plate 42 on its inner wall. The elastic impact plate 42 then generates high-frequency vibration, continuously striking the inner wall of the hopper, causing the sludge adhering to the wall surface to be shaken off, effectively preventing the accumulation of material on the inner wall of the hopper.
[0038] Meanwhile, the intelligent control system operates as follows: Controller 15 monitors the sludge height inside the hopper shell 21 in real time via a level sensor. When the sludge level is high, indicating an increased risk of blockage, controller 15 increases the speed of the drive motor of the conveyor chain 12 via the frequency converter 16, thereby increasing the operating speed of the suspended scraper assembly 13. This causes the scraper assembly 13 to pass through the trigger-type transmission assembly 3 more frequently, thereby increasing the intermittent rotation frequency of the active arch-breaking screw 22 and enhancing the arch-breaking and wall-cleaning effects. Conversely, when the sludge level is low, controller 15 reduces the speed of the conveyor chain 12 and decreases the triggering frequency to save energy and reduce unnecessary mechanical wear. Position sensor 14 is used to accurately confirm the position of the scraper assembly, ensuring that control commands are executed at the correct time.
[0039] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
