Description

Technical Field

[0001] This invention relates to the field of incinerator technology, and in particular to a continuous ash removal system and method for incinerators. Background Technology

[0002] During the incineration of various wastes, incinerators produce a large amount of slag, which needs to be discharged in a timely manner through a slag removal system to ensure the continuous and stable operation of the incinerator. Currently, the mainstream slag removal method for incinerators mostly adopts screw conveyors, which are widely used due to their compact structure and stable conveying efficiency. However, slag itself has the characteristics of uneven particle size, rough surface and complex composition. During the conveying process, irregular friction is easily generated between the slag and the screw conveyor blades and the inner wall of the feeding cylinder. When the local friction is too large, the slag will gradually accumulate and form a blockage, which will hinder the operation of the slag removal system.

[0003] Existing ash removal systems lack effective automatic handling mechanisms when facing blockage problems, usually requiring manual intervention after shutdown. Operators need to use special tools to disassemble and manually unclog pipes, which is not only cumbersome and time-consuming, but also seriously affects the continuous operation efficiency of the incinerator. It may also pose safety hazards due to contact with high-temperature ash or equipment parts. In addition, frequent pipe disassembly and assembly will also accelerate equipment wear and reduce the overall service life of the system. Based on this, a continuous ash removal system and ash removal method for incinerators are proposed. Summary of the Invention

[0004] To overcome the problems existing in related technologies, the present invention provides a continuous ash removal system and method for incinerators. By embedding a pressure sensor in the movable sealing plate, the system monitors the pressure changes in the feeding cylinder in real time. When the ash accumulation causes the pressure to exceed a preset threshold, the system can automatically trigger the pressure relief and blockage removal process. The controller simultaneously closes the electric control valve to stop feeding and drives the movable sealing plate to move down and open the pressure relief port, quickly releasing the ash and pressure in the blocked area and preventing the blockage from expanding. The entire process does not require machine shutdown or manual intervention.

[0005] To achieve the above objectives, the present invention provides a continuous ash removal system for an incinerator, comprising an ash removal component and a discharge pipe, one end of which is sealed to the ash removal port of the incinerator, and an electrically controlled valve is installed on the discharge pipe. The ash removal component includes a feeding cylinder and an auger feeding section, and at least one pressure relief port is provided at the bottom end of the feeding cylinder. The system also includes: At least one movable sealing plate is provided, and a liftable movable sealing plate is provided in each of the pressure relief ports. The movable sealing plate is sealed to the inner wall of the pressure relief port, and a pressure sensor is embedded in the movable sealing plate. At least one movable sealing component is hinged to the movable sealing plate. When the pressure sensor detects that the pressure inside the feed cylinder exceeds a preset threshold, the movable sealing component drives the movable sealing plate to move downward to open the corresponding pressure relief port. The follower deflector is linked to the auger feeding section and the movable sealing plate. After the movable sealing plate moves down to open the pressure relief port, the auger feeding section drives the follower deflector to deflect. Through the periodic deflection force of the follower deflector, the hinged movable sealing plate is driven to periodically tilt and discharge material.

[0006] Preferably, each of the active plugging components includes: Two mounting sleeves are symmetrically fixed to the outside of the feeding cylinder and located on both sides of the pressure relief port, and a connecting block is fixed on the mounting sleeve; A horizontal plate is connected between the two connecting blocks; A telescopic rod is installed through the horizontal plate, with the telescopic end of the rod facing upward and hinged to the lower end face of the movable sealing plate.

[0007] Preferably, the lower end face of the movable sealing plate is also hinged with a guide rod, and a guide groove is provided on the horizontal plate, through which the guide rod slides.

[0008] Preferably, the auger feeding section includes a drive motor, and the output end of the drive motor is connected to a conveying auger inside the feeding cylinder via a connecting shaft.

[0009] Preferably, the feeding end of the feeding cylinder is connected to a receiving hopper, which is located below the discharge pipe.

[0010] Preferably, the follow-up deflection component includes a linkage component and a magnetic switching component. One end of the linkage component is connected to the connecting shaft of the output end of the drive motor, and the other end is fixedly connected to the magnetic switching component. The magnetic switching component is magnetically engaged with the movable sealing plate.

[0011] Preferably, the linkage includes a synchronous connector, one end of which is connected to the connecting shaft at the output end of the drive motor, and the other end is fixed with a connecting rod, both ends of which are equipped with bearing seats.

[0012] Preferably, the magnetic switching component includes a repulsion component, which includes a convex ring fixed to the outside of the connecting rod. Multiple convex strips are fixed in a ring array on the outer circumference of the convex ring, and a magnetic block is fixed to the end of each convex strip.

[0013] Preferably, a magnetic strip is fixed to one side of the lower end face of the movable sealing plate, the magnetic strip and the magnetic block repel each other, and a return spring is connected to the other side of the lower end face of the movable sealing plate.

[0014] The present invention also provides a method for continuous ash removal from an incinerator, employing the aforementioned continuous ash removal system for an incinerator, comprising the following steps: S1. The slag produced by the incinerator is discharged from the slag discharge port to the discharge pipe, and falls into the receiving hopper through the discharge pipe. It is then guided into the feeding cylinder by the receiving hopper. The drive motor is started to drive the conveying auger to rotate. The conveying auger transports the slag to the discharge end of the feeding cylinder to achieve continuous slag discharge. S2. The pressure in the feeding cylinder is monitored in real time by the pressure sensor on the movable sealing plate. When the pressure exceeds the preset threshold, the controller simultaneously starts the electric control valve and the telescopic rod. The electric control valve closes the discharge pipe to stop feeding, and the telescopic rod drives the movable sealing plate to move down, opening the pressure relief port to release some slag and quickly relieve the blockage and overpressure in the feeding cylinder. S3. The drive motor continuously drives the connecting shaft to rotate, and through the synchronous connector, it drives the connecting rod and the convex ring to rotate synchronously. The magnetic block on the convex ring rotates with the convex ring and periodically generates a repulsive force on the magnetic strip on the movable sealing plate. Under the action of the repulsive force, the movable sealing plate tilts periodically around the hinge point with the telescopic rod, so that the slag accumulated on the movable sealing plate slides out of the pressure relief port along the inclined surface. S4. After depressurization for a period of time, the telescopic rod moves the movable sealing plate upward, so that the movable sealing plate seals with the pressure relief port, closes the pressure relief port, and at the same time opens the electric control valve to resume feeding, and the system returns to normal continuous slag discharge state.

[0015] The technical solution provided by this invention may include the following beneficial effects: 1. In this invention, by embedding a pressure sensor in the movable sealing plate, the pressure change in the feeding cylinder is monitored in real time. When the pressure exceeds the preset threshold due to slag accumulation, the system can automatically trigger the pressure relief and blockage removal process. The controller simultaneously closes the electric control valve to stop feeding and drives the movable sealing plate to move down and open the pressure relief port, quickly releasing the slag and pressure in the blocked area and preventing the blockage from expanding. The entire process does not require machine shutdown or manual intervention, effectively solving the drawback of traditional slag removal systems that require disassembly and unblocking after blockage. This improves the continuous operating efficiency of the incinerator and slag removal system and reduces the production capacity loss caused by downtime.

[0016] 2. In this invention, through the linkage design of the follower deflection component and the auger feeding part, the existing power of the drive motor drives the magnetic switching component to rotate. Through the periodic repulsive force between the magnetic block and the magnetic strip of the movable sealing plate, combined with the elastic force of the return spring, the movable sealing plate is driven to tilt periodically around the hinge point, so that the slag accumulated on the sealing plate can slide smoothly out along the inclined surface, avoiding the problem of poor sealing caused by slag adhesion and residue. In normal slag discharge state, the movable sealing plate and the pressure relief port are tightly matched by the sealing rubber ring, which can effectively block the pressure relief port and prevent slag leakage, thus achieving a dual guarantee of slag discharge effect and system sealing performance.

[0017] 3. In this invention, the pressure relief ports are evenly distributed along the length of the feeding cylinder, which can accurately relieve pressure in different sections with abnormal pressure, avoid local pressure concentration from impacting the equipment, and at the same time, eliminate the need for frequent disassembly and assembly of pipelines, reduce equipment wear and maintenance frequency, and extend the overall service life of the slag discharge system.

[0018] 4. In this invention, the follower deflection component is directly linked by the drive motor of the auger feeding part, without the need for an additional power source, which simplifies the system structure and reduces energy consumption.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this invention. Preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawings. Although preferred embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the invention more thorough and complete, and to fully convey the scope of the invention to those skilled in the art.

[0024] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] Example 1: See Figures 1-9As shown, this invention proposes a continuous ash removal system for an incinerator, including an ash removal component 1, a discharge pipe 2, and a controller (not shown). The discharge pipe 2 serves as a transition channel for ash from the incinerator to the subsequent conveying structure. One end of the discharge pipe is tightly sealed to the ash removal port of the incinerator through a high-temperature resistant sealing component. An electrically controlled valve 3 is installed on the discharge pipe 2. The electrically controlled valve 3 is made of high-temperature resistant and wear-resistant material and can be quickly opened and closed under the command of the controller. The ash removal component 1 includes a feeding cylinder 101 and an auger feeding section. The auger feeding section includes a drive motor 102. The drive motor 102 is a variable frequency motor with sufficient torque and protection level, which can adjust the output speed according to the amount of ash produced, thereby controlling the conveying rate and adapting to the different operating conditions of the incinerator. A conveying auger 103 is mounted on the output end of the motor 102 via a connecting shaft. The conveying auger 103 is coaxially arranged inside the feeding cylinder 101. The blades of the conveying auger 103 are made of wear-resistant alloy material, which can effectively resist the erosion and wear of high-temperature slag and extend its service life. The conveying auger 103 pushes the slag in the feeding cylinder 101 from the inlet end to the outlet end by rotating, realizing continuous slag conveying. A receiving hopper 5 is connected to the upper end of the feeding cylinder 101. The receiving hopper 5 is located below the discharge pipe 2. The upper opening size of the receiving hopper 5 is larger than the lower outlet size of the discharge pipe 2. The receiving hopper 5 is used to receive the slag discharged from the discharge pipe 2 and guide it into the feeding cylinder 101. The inner wall of the receiving hopper 5 is provided with a smooth wear-resistant liner to reduce slag falling. The resistance and wear on the bucket body are reduced to allow the slag to be smoothly fed into the feeding cylinder 101. At least one pressure relief port 104 is provided at the bottom of the feeding cylinder 101, and the pressure relief ports 104 are evenly distributed along the length of the feeding cylinder 101. This allows for pressure relief in different sections to address pressure anomalies. The system also includes a movable sealing plate 4 and a movable sealing assembly 7, with at least one movable sealing plate 4 and one movable sealing assembly 7. Each pressure relief port 104 has a corresponding movable sealing plate 4, ensuring independent control and sealing of each individual pressure relief port 104. The movable sealing plate 4 is made of high-temperature resistant, high-strength steel plate, and its dimensions match the inner wall dimensions of the pressure relief port 104. A high-temperature resistant sealing ring is installed between the movable sealing plate 4 and the inner wall of the pressure relief port 104. This achieves a tight seal between the two components. Under normal slag discharge conditions, it can effectively seal the pressure relief port 104, preventing slag in the feeding cylinder 101 from leaking out of the pressure relief port 104. Furthermore, a pressure sensor 41 is embedded in the movable sealing plate 4. The pressure sensor 41 is a high-temperature resistant pressure detection element. Its detection end is connected to the inside of the feeding cylinder 101, enabling it to monitor the pressure value in the corresponding section of the feeding cylinder 101 in real time and transmit the detected pressure signal to the controller in real time, providing data support for judging pressure anomalies. The movable sealing component 7 is hinged to the movable sealing plate 4. When the pressure sensor 41 detects that the pressure in the feeding cylinder 101 exceeds the preset threshold, the movable sealing component 7 drives the movable sealing plate 4 to move down, thereby opening the corresponding pressure relief port 104 to release pressure and remove the blockage.

[0026] Among them, see Figures 3-8 As shown, each movable sealing assembly 7 includes a mounting sleeve 71 and a telescopic rod 73. There are two mounting sleeves 71, which are symmetrically fixed to the outside of the feeding cylinder 101 and located on both sides of the pressure relief port 104. A connecting block 76 is fixed on the mounting sleeve 71, and a horizontal plate 72 is connected between the two connecting blocks 76. The telescopic rod 73 is preferably an electric telescopic rod. The telescopic rod 73 is installed through the horizontal plate 72, with the telescopic end of the telescopic rod 73 facing upward and hinged to the lower end face of the movable sealing plate 4. The movable sealing plate 4 is driven to rise and fall by the telescopic rod 73.

[0027] As described above, under normal operating conditions, the controller keeps the electrically controlled valve 3 open. The slag produced by the incinerator falls through the slag discharge port into the discharge pipe 2, and then is discharged through the discharge pipe 2 to the receiving hopper 5 below. The slag is guided into the feeding cylinder 101 through the receiving hopper 5. At this time, the controller starts the drive motor 102, which drives the conveying auger 103 to rotate. Through the pushing action of the blades of the conveying auger 103, the slag is continuously conveyed along the length of the feeding cylinder 101 to the designated collection position, completing the normal slag discharge process. During this process, the movable sealing plate 4 is in the closed state. The pressure sensor 41 monitors the pressure value of the corresponding section in the feeding cylinder 101 in real time and feeds the data back to the controller in real time. If slag accumulates or becomes blocked in the feeding cylinder 101, the pressure in the corresponding section will rise sharply. When the pressure sensor... When the pressure value detected by sensor 41 exceeds the preset pressure threshold of the controller, pressure sensor 41 immediately sends an abnormal signal to the controller. Upon receiving the abnormal signal, the controller responds quickly by simultaneously activating telescopic rod 73 and controlling solenoid valve 3. On one hand, solenoid valve 3 quickly closes, temporarily cutting off the feed channel of discharge pipe 2 to prevent subsequent slag from continuously entering the feeding cylinder 101 and to prevent further aggravation of the blockage. On the other hand, the telescopic rod 73 of the corresponding section is activated, driving the movable sealing plate 4 to move down synchronously, separating the movable sealing plate 4 from the inner wall of pressure relief port 104, thereby opening the corresponding pressure relief port 104. At this time, excess slag in the blockage area of ​​the feeding cylinder 101 can be quickly discharged through pressure relief port 104, achieving rapid unblocking, effectively relieving the pressure in the feeding cylinder 101, and preventing the blockage area from expanding and equipment damage.

[0028] The controller has a preset pressure relief time of 1-3 minutes, which can be adjusted according to the actual working conditions and the degree of blockage. After the pressure relief is completed, the controller issues another command to control the telescopic rod 73 to extend and retract upwards, driving the movable sealing plate 4 to move upwards and reset. The sealing ring re-seales with the inner wall of the pressure relief port 104, thus sealing the pressure relief port 104. At the same time, the controller controls the electric control valve 3 to reopen, restoring the feeding of the discharge pipe 2. The drive motor 102 continues to operate normally, and the system resumes normal continuous slag discharge operation. This fault handling process is completed automatically without the need for manual cleaning, which shortens the fault handling time, improves the overall processing efficiency of the slag discharge system, and effectively reduces the labor intensity and safety risks associated with manual cleaning. In addition, through precise pressure monitoring and targeted pressure relief, the pressure relief port 104 can be quickly reset and sealed after pressure relief, minimizing slag leakage and ensuring the normal slag discharge operation of the system and the stable operation of the incinerator.

[0029] Furthermore, a guide rod 74 is hinged to the lower end face of the movable sealing plate 4, and a guide groove 75 is provided on the horizontal plate 72. The end of the guide rod 74 away from the movable sealing plate 4 slides through the guide groove 75. When the movable sealing plate 4 is raised or lowered, the guide rod 74 and the guide groove 75 cooperate to limit the raising and lowering trajectory of the movable sealing plate 4.

[0030] Example 2: See Figures 1-6 as well as Figure 10 As shown, this embodiment is an extension based on embodiment one. The continuous ash discharge system of the incinerator also includes a follower deflector 6. The follower deflector 6 is linked with the screw conveyor feeding part and the movable sealing plate 4 respectively. By using the existing driving force of the screw conveyor feeding part, the movable sealing plate 4 can be driven to complete the periodic discharge action without the need for an additional power source. After the movable sealing plate 4 moves down to open the pressure relief port 104, the screw conveyor feeding part drives the follower deflector 6 to deflect. Through the periodic deflection force of the follower deflector 6, the hinged movable sealing plate 4 is driven to periodically tilt and discharge material.

[0031] Among them, see Figures 4-6 As shown, the follower deflection component 6 includes a linkage component 61 and a magnetic switching component 62. One end of the linkage component 61 is connected to the connecting shaft of the output end of the drive motor 102, and the other end is fixedly connected to the magnetic switching component 62. The magnetic switching component 62 is magnetically engaged with the movable sealing plate 4.

[0032] The linkage 61 includes a synchronous connector 611, which consists of two synchronous pulleys and a synchronous belt. One synchronous pulley is connected to the connecting shaft at the output end of the drive motor 102. A connecting rod 612 is fixed on the other synchronous pulley. The connecting rod 612 is made of high-strength alloy material and has sufficient torsional strength and rigidity. Bearing seats 613 are installed at both ends of the connecting rod 612. The bearing seats 613 are used to provide rotational support for the connecting rod 612.

[0033] See Figure 10 As shown, the magnetic switching component 62 includes a repulsion component 621. The repulsion component 621 includes a protruding ring 6211 fixed to the outside of the connecting rod 612. Multiple protruding strips 6212 are fixed in a ring array on the outer circumference of the protruding ring 6211. A magnetic block 6213 is fixed to the end of the protruding strip 6212. The magnetic block 6213 is made of high-strength permanent magnet material, which has a stable magnetic field strength and long-lasting magnetism and is not prone to magnetic attenuation. A magnetic strip 622 is fixed to one side of the lower end face of the movable sealing plate 4. The magnetic strip 622 and the magnetic block 621 The opposite sides of 3 are magnetic poles of the same name, realizing the magnetic repulsion between them. A reset spring is connected to the other side of the lower end face of the movable sealing plate 4. The reset spring is used to reset the movable sealing plate 4 after it is deflected. The bottom end of the reset spring can be connected to the outer wall of the horizontal plate 72 or the guide rod 74 through the connecting bracket. The reset spring is a high-strength compression spring with good elastic recovery performance. Its elastic force matches the repulsive force of the magnetic block 6213 on the magnetic strip 622, ensuring that the movable sealing plate 4 can quickly reset after the repulsive force disappears.

[0034] As described above, after the movable sealing plate 4 lowers to open the pressure relief port 104, slag will directly accumulate on the surface of the movable sealing plate 4. If the slag accumulates for a long time and is not cleaned in time, it may cause problems with sealing the pressure relief port 104 when it is subsequently sealed due to slag clumping and adhesion. The drive motor 102 starts and drives the connecting shaft to rotate synchronously. The rotation of the connecting shaft drives the synchronous connecting member 611 to rotate, thereby realizing the directional rotation of the repulsion member 621. During the rotation of the repulsion member 621, the magnetic block 6213 on it will change position with the rotation of the repulsion member 621. When the magnetic block 6213 rotates to the magnetic strip 622 near the movable sealing plate 4, the repulsive force between the two directly acts on the movable sealing plate 4, pushing the movable sealing plate 4 to deflect at a certain angle, realizing the tilting action of the movable sealing plate 4. The coal slag accumulated on the movable sealing plate 4 will automatically slide down the tilted plate surface under the action of gravity, completing the non-contact automatic cleaning of the coal slag. This not only avoids the hard adhesion of coal slag to the sealing plate, but also allows the movable sealing plate 4 to return to the unloaded state, which is convenient for subsequent reset to seal the pressure relief port 104, reducing the probability of coal slag getting stuck on the inner wall of the pressure relief port 104 or the contact point of the movable sealing plate 4.

[0035] Secondly, the follow-up deflection component 6 can achieve autonomous linkage through the power of the drive motor 102, without the need for an additional control unit, which simplifies the system structure, reduces equipment manufacturing costs and maintenance difficulty. At the same time, through the combination structure of magnetic drive and spring reset, the periodic tilting discharge of the movable sealing plate 4 is realized, which ensures the efficiency and stability of the pressure relief and slag discharge process and avoids slag accumulation and equipment blockage.

[0036] This invention also proposes a continuous ash removal method for an incinerator, employing the aforementioned continuous ash removal system for an incinerator, comprising the following steps: S1. The slag produced by the incinerator is discharged from the slag discharge port to the discharge pipe 2, and falls into the receiving hopper 5 through the discharge pipe 2. It is then guided into the feeding cylinder 101 by the receiving hopper 5. The drive motor 102 is started to drive the conveying auger 103 to rotate. The conveying auger 103 conveys the slag to the discharge end of the feeding cylinder 101 to achieve continuous slag discharge. S2. The pressure inside the feeding cylinder 101 is monitored in real time by the pressure sensor 41 on the movable sealing plate 4. When the pressure exceeds the preset threshold, the controller simultaneously starts the electric control valve 3 and the telescopic rod 73. The electric control valve 3 closes the discharge pipe 2 to stop feeding. The telescopic rod 73 drives the movable sealing plate 4 to move down, opening the pressure relief port 104 to release some slag and quickly relieve the blockage and overpressure state inside the feeding cylinder 101. S3. The drive motor 102 continuously drives the connecting shaft to rotate, and drives the connecting rod 612 and the convex ring 6211 to rotate synchronously through the synchronous connector 611. The magnetic block 6213 on the convex ring 6211 rotates with the convex ring 6211, and periodically generates a repulsive force on the magnetic strip 622 on the movable sealing plate 4. Under the action of the repulsive force and the elastic force of the return spring, the movable sealing plate 4 tilts periodically around the hinge point with the telescopic rod 73, so that the slag accumulated on the movable sealing plate 4 slides out of the pressure relief port 104 along the inclined surface. S4. After depressurization for a period of time, the telescopic rod 73 moves the movable sealing plate 4 upward, so that the movable sealing plate 4 and the pressure relief port 104 are sealed and closed, and at the same time the electric control valve 3 is opened to resume feeding, and the system returns to the normal continuous slag discharge state.

10. A method for continuous ash removal from an incinerator, employing the continuous ash removal system for an incinerator as described in any one of claims 1-9, characterized in that, Includes the following steps: S1. The slag produced by the incinerator is discharged from the slag discharge port to the discharge pipe (2), and falls into the receiving hopper (5) through the discharge pipe (2). It is then guided into the feeding cylinder (101) by the receiving hopper (5). The drive motor (102) is started to drive the conveying auger (103) to rotate. The slag is conveyed to the discharge end of the feeding cylinder (101) through the conveying auger (103) to achieve continuous slag discharge. S2. The pressure in the feeding cylinder (101) is monitored in real time by the pressure sensor (41) on the movable sealing plate (4). When the pressure exceeds the preset threshold, the controller simultaneously starts the electric control valve (3) and the telescopic rod (73). The electric control valve (3) closes the discharge pipe (2) to stop feeding. The telescopic rod (73) drives the movable sealing plate (4) to move down and open the pressure relief port (104) to release some slag and quickly relieve the blockage and overpressure state in the feeding cylinder (101). S3. The drive motor (102) continuously drives the connecting shaft to rotate, and drives the connecting rod (612) and the convex ring (6211) to rotate synchronously through the synchronous connector (611). The magnetic block (6213) on the convex ring (6211) rotates with the convex ring (6211) and periodically generates a repulsive force on the magnetic strip (622) on the movable sealing plate (4). Under the action of the repulsive force and the return spring, the movable sealing plate (4) tilts periodically around the hinge point with the telescopic rod (73), so that the slag accumulated on the movable sealing plate (4) slides out of the pressure relief port (104) along the inclined surface. S4. After depressurization for a period of time, the telescopic rod (73) moves the movable sealing plate (4) upward, so that the movable sealing plate (4) seals with the depressurization port (104), closes the depressurization port (104), and at the same time opens the electric control valve (3) to resume feeding, and the system returns to normal continuous slag discharge state.
