Description

Technical Field

[0001] This invention relates to the field of waste incineration power generation technology, specifically to an ash conveying mechanism for an anti-clogging boiler flue in waste incineration power generation system. Background Technology

[0002] In the field of waste-to-energy incineration, the stable operation of the boiler flue ash conveying system is crucial, directly affecting the efficiency and continuity of the entire power generation system. Existing ash conveying technologies generally combine mechanical conveying with gravity flow. A common structure involves placing an ash hopper at the bottom of the boiler flue, where fly ash falls naturally under gravity, then undergoes initial guidance by fixed guide plates or inclined baffles below, and finally enters mechanical conveying equipment such as screw conveyors or scraper conveyors for centralized discharge. To prevent blockages, some systems supplement this with simple bin vibrators or intermittent high-pressure air blowing devices, attempting to maintain smooth ash flow through external disturbance. The control of the entire process largely relies on empirical timed start-stop modes or simple level switch signals, lacking real-time sensing and fine-tuning of the internal state of the ash conveying channel.

[0003] However, the aforementioned existing technologies have revealed many shortcomings in actual operation. The core problem lies in the passive and inefficient nature of the ash conveying process. The fixed flow guide structure cannot adapt to the complex and variable ash properties and ash volume fluctuations under incineration conditions, easily forming ash bridges or adhering deposits on the surface of the guide plate and in the corners of the chamber, gradually developing into stubborn blockages. Mechanical vibration and air blowing measures often have limited range of action and dispersed energy, proving ineffective in clearing already hardened ash blocks and potentially exacerbating localized wear. Simultaneously, due to the lack of precise monitoring of pressure changes and the actual state of ash flow within the chamber, operators struggle to detect potential blockage risks in a timely manner, often only responding passively when the problem becomes severe enough to affect system output, leading to frequent unplanned shutdowns for maintenance. This passive approach not only increases maintenance workload and costs but also significantly impacts the stability and economy of power generation. Therefore, we propose an anti-blockage ash conveying mechanism for waste incineration power generation boiler flues. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide an ash conveying mechanism for a waste incineration power generation boiler flue that prevents blockage. Through the dynamic angle adjustment of the rotatable baffle plate and the active unblocking mechanism that combines high-pressure air blowing and mechanical vibration, it can effectively avoid blockage and unstable ash flow, and can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an ash conveying mechanism for an anti-clogging boiler flue of a waste incineration power generation system, comprising an ash conveying box and a flow guiding component; Ash conveying box: A second pressure sensor is installed inside. Two corresponding connecting components are installed on the upper and lower sides of the ash conveying box. A discharge component is installed below the lower connecting component. Vibration components are installed on the left and right sides of the ash conveying box. The vibration components are connected to the two connecting components. An air injection component is installed on the front side of the ash conveying box. A moving component and an adjusting component are installed on the rear side of the ash conveying box. The moving component and the adjusting component are connected. The second pressure sensor is bidirectionally electrically connected to an external PLC controller. The flow guiding assembly includes rotating drums, air jet pipes, one-way valves, and baffles. Four staggered rotating drums are located at the left and right ends of the ash conveying box. Evenly distributed rotating holes are provided on both the front and rear sides of the ash conveying box. Each end of a rotating drum is rotatably connected to the interior of its corresponding two rotating holes. Baffles are fixed to the circumference of each rotating drum, and evenly distributed air jet holes are provided on the circumference of each rotating drum. Air jet pipes are fixed inside the air jet holes, and one-way valves are installed on the circumference of the air jet pipes. Air inlet assemblies are installed at the front ends of the four rotating drums, and the air injection assembly is connected to the air inlet assembly. By setting up the flow guiding assembly, the tilt angle of the baffles can be adjusted according to requirements during use, thereby controlling the dust flow rate.

[0006] Furthermore, the air intake assembly includes a rotating pipe, a fixed frame, a connecting pipe, and a fixed pipe. The rotating pipe is rotatably connected to the front end of the rotating drum, and four corresponding fixed frames are fixed to the front side of the ash conveying box. A connecting hole is opened in the middle of the fixed frame, and the rotating pipe is rotatably connected to the inside of the corresponding connecting hole. The four rotating pipes on the left and right are connected by two connecting pipes, and the two connecting pipes are connected by a fixed pipe. By setting the air intake assembly, the compressed air generated by the air pump is injected into the inside of the four jet pipes, and then sprayed onto the baffle plate through the evenly distributed jet pipes. In this way, the dust on the baffle plate can be blown away, preventing the dust from accumulating on the baffle plate.

[0007] Furthermore, the air injection assembly includes an air pump and an air outlet hose. An air pump is installed on the front side of the ash conveying box, and an air outlet hose is fixed inside the air outlet of the air pump. The upper end of the air outlet hose is connected to a fixed pipe. The input end of the air pump is electrically connected to the output end of an external PLC controller. Compressed gas is injected into the interior of the fixed pipe by setting the air injection assembly.

[0008] Furthermore, the adjustment assembly includes an angle sensor, a fixed bucket, a gear ring, a rack, and a protective shell. Four angle sensors are mounted on the rear side of the ash conveying box, and the rear ends of the four rotating buckets are respectively fixed inside the four angle sensors. A fixed bucket is fixed to the rear end of each rotating bucket, and a gear ring is fixed to the circumference of the fixed bucket. Two racks are arranged between the four gear rings, and the racks mesh with their adjacent two gear rings. A protective shell is fixed to the rear side of the ash conveying box, and the gear rings and racks are located inside the protective shell. The angle sensors are bidirectionally electrically connected to an external PLC controller, and the rotation angle of the rotating buckets is continuously detected by the angle sensors.

[0009] Furthermore, the moving component includes a fixed frame, fixed strips, a first pressure sensor, a mounting bracket, a motor, a threaded rod, and a limiting rod. The fixed frame is located inside the protective shell, with two racks fixed to the left and right sides of the fixed frame respectively. Two corresponding fixed strips are fixed to the rear side of the ash conveying box. The first pressure sensor is mounted on the side of each fixed strip. The upper fixed strip is located inside the fixed frame. A threaded hole is opened on the lower side of the fixed frame, and a threaded rod is threadedly connected inside the threaded hole. The threaded rod is rotatably connected between the two fixed strips. A limiting hole is opened on the lower side of the fixed frame, and a limiting rod is slidably connected inside the limiting hole. The limiting rod is fixed between the two fixed strips. A mounting bracket is fixed to the upper side of the upper fixed strip, and a motor is installed inside the mounting bracket. The output shaft of the motor is fixed to the upper end of the threaded rod. The input end of the motor is electrically connected to the output end of an external PLC controller. The first pressure sensor is bidirectionally electrically connected to the external PLC controller. The moving component drives all the rotating drums to rotate.

[0010] Furthermore, the connecting assembly includes a chute, a rubber frame, a connecting frame, and a support plate. The ash conveying box has chutes on both the upper and lower sides. A rubber frame is slidably connected inside the chute. A connecting frame is fixed to the side of the rubber frame. A support plate is fixed to the side of the connecting frame. The ash conveying box is supported by the two connecting assemblies.

[0011] Furthermore, the vibration assembly includes a vibration motor, a fixing plate, and springs. Vibration motors are installed on both the left and right sides of the ash conveying box, and fixing plates are fixed on both the left and right sides of the ash conveying box. Springs are evenly distributed on the upper and lower sides of the fixing plates. All the springs are fixed on the sides of their corresponding support plates. The input end of the vibration motor is electrically connected to the output end of an external PLC controller. By setting the vibration assembly, the ash conveying box is driven to vibrate, thus preventing dust from sticking to the inner wall of the ash conveying box.

[0012] Furthermore, the discharge assembly includes a conical discharge box, a discharge pipe, and a solenoid valve. An opening is provided on the lower side of the support plate, and the conical discharge box is fixed inside the opening. A discharge pipe is fixed on the lower side of the conical discharge box, and a solenoid valve is installed on the surface of the discharge pipe. The input end of the solenoid valve is electrically connected to the output end of an external PLC controller. Ash is discharged by setting up the discharge assembly.

[0013] Furthermore, an ash injection port is provided on the upper side of the upper support plate, and a feed pipe is fixed inside the ash injection port. A connecting flange ring is fixed at the upper end of the circumferential surface of the feed pipe, and the dust inside the boiler flue enters the ash conveying box through the feed pipe.

[0014] Furthermore, the ash conveying box is provided with a fixing shell on both the left and right sides. The two fixing shells are fixed to the surface of the ash conveying box by evenly distributed bolts, and the fixing shells are used to protect the vibrating motor.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This ash conveying mechanism for the anti-clogging flue of a waste incineration power generation boiler has the following advantages: 1. Multiple rotatable baffles are incorporated, their tilt angles no longer fixed but flexibly adjustable based on actual ash volume characteristics and conveying requirements. When the ash volume is large or the ash is viscous, the baffle angle can be appropriately increased to allow the ash flow to pass through quickly; when it is necessary to slow the flow rate to facilitate subsequent processing or prevent dust generation, the tilt angle can be decreased to increase the residence time of the ash flow within the chamber. This dynamic adjustment capability fundamentally changes the passive mode of traditional fixed baffles, ensuring that the ash conveying process remains under control and significantly reducing the risk of blockage caused by improper flow rate.

[0016] 2. The system optimizes the ash flow path through the mechanical guiding effect of the baffles and innovatively introduces an active unblocking mechanism combining high-pressure air blowing and mechanical vibration. When the second pressure sensor detects abnormal pressure inside the box or determines that there is a tendency for ash accumulation, the system can automatically start the air pump to precisely blow compressed air onto the surface of the baffles through the jet pipes arranged on the rotating drum, effectively peeling off the adhered ash clumps. At the same time, the vibration motor drives the entire ash conveying box to generate high-frequency micro-amplitude vibration, making it difficult for ash to adhere to the box walls and components and allowing it to slide down smoothly. This cleaning method, which combines pneumatics and vibration, is direct and energy-concentrated, and can efficiently break down initial ash bridges and accumulations, preventing them from developing into serious blockages. 3. The entire mechanism is centrally controlled by an external PLC controller, which continuously receives signals from pressure and angle sensors to monitor the working pressure inside the chamber and the actual angle of the baffles in real time. Based on this data, the controller can make intelligent decisions, automatically adjusting the baffle angle, starting and stopping the air pump and vibration motor, and controlling the opening and closing of the discharge valve, forming a complete closed-loop control. This completely changes the past reliance on manual periodic inspections and experience-based operation, not only reducing the burden on operators but also ensuring the long-term stable and continuous operation of the boiler flue ash conveying system.

Four staggered rotating drums 21 are arranged at the left and right ends inside the ash conveying box 1. Evenly distributed rotating holes are opened on both the front and rear sides of the ash conveying box 1.

The four rotating pipes 61 on the left and right are connected by two connecting pipes 63 respectively. The two connecting pipes 63 are connected by a fixed pipe 64. By setting the air intake component 6, the compressed air generated by the air pump 91 is injected into the inside of the four jet pipes 22. Then, it is sprayed onto the baffle plate 24 through the evenly distributed jet pipes 22. In this way, the dust on the baffle plate 24 can be blown away, preventing the dust from accumulating on the baffle plate 24. By setting the flow guide component 2, the tilt angle of the baffle plate 24 can be adjusted according to the needs during use, thereby controlling the flow rate of the dust.

[0021] Among them: the upper side of the support plate 54 is provided with an ash injection port, and the inside of the ash injection port is fixed with a feed pipe 10. The upper end of the circumferential surface of the feed pipe 10 is fixed with a connecting flange ring 11. The dust inside the boiler flue enters the ash conveying box 1 through the feed pipe 10.

[0023] The working principle of the ash conveying mechanism for a waste incineration power generation anti-clogging boiler flue provided by the present invention is as follows: After the dust enters the ash conveying box 1 through the feed pipe 10, it is first processed by the flow guiding component 2. The baffle 24 on the rotating drum 21 monitors the rotation angle in real time through the angle sensor 31 of the adjustment component 3. The motor 45 of the moving component 4 drives the threaded rod 46 to rotate, causing the fixed frame 41 to drive the rack 34 to move, thereby engaging the gear ring 33 to precisely adjust the angle of the rotating drum 21, so as to control the flow rate and distribution of dust and prevent local accumulation. At the same time, the air pump 91 of the air injection component 9 injects compressed air into the fixed pipe 64 of the air intake component 6 through the air outlet hose 92, and distributes it to the jet pipe 22 inside the rotating drum 21 through the connecting pipe 63 and the rotating pipe 61. It is then sprayed out evenly through the one-way valve 23. Airflow effectively sweeps the surface of the baffle plate 24, preventing dust adhesion. The vibration motor 71 of the vibration assembly 7 transmits vibration to the ash conveying box 1 through the fixed plate 72 and spring 73, causing the box to shake slightly but continuously, further preventing dust from accumulating on the inner wall. The conical discharge box 81 of the discharge assembly 8 collects the processed dust, and the opening and closing of the discharge pipe 82 is controlled by the solenoid valve 83 for orderly discharge. Throughout the process, the second pressure sensor 14 continuously monitors the pressure changes inside the ash conveying box 1, and the first pressure sensor 43 detects the position feedback of the moving assembly 4. All data are intelligently analyzed by the external PLC controller, which automatically adjusts the angle of the baffle plate 24, the vibration frequency, and the timing of air blowing to achieve adaptive and efficient anti-clogging operation, ensuring smooth ash flow and stable system operation.

[0024] It is worth noting that the external PLC controller disclosed in the above embodiments is specifically a Siemens S7-200. The angle sensor 31, the first pressure sensor 43, the second pressure sensor 14, the motor 45, the vibration motor 71, the solenoid valve 83, and the air pump 91 can be freely configured according to the actual application scenario. The external PLC controller controls the operation of the motor 45, the vibration motor 71, the solenoid valve 83, and the air pump 91 using methods commonly used in the prior art.
