Abstract
Description
Technical Field
[0001] This invention relates to the field of ash removal equipment technology, and in particular to an ash silo gasification device. Background Technology
[0002] Ash silos are facilities used in industries such as thermal power generation, metallurgy, and chemicals to store dry powdery materials such as fly ash, cement, and limestone powder. The gasification unit is a crucial component at the bottom of the ash silo; its function is to introduce dry air into the ash material through gasification plates, fluidizing the ash and facilitating smooth unloading.
[0003] Currently, the micropores of the gasification plates in traditional ash silo gasification devices are easily clogged by damp ash particles or fine particles, leading to decreased air permeability and poor fluidization. Clogging often necessitates shutdown, requiring manual entry into the ash silo for cleaning or replacement of the gasification plates. This involves harsh working conditions, high labor intensity, and disruption to production continuity. The lack of effective online monitoring methods makes it impossible to predict clogging; problems are usually only discovered when unloading becomes obstructed, by which time it is often too late. Therefore, there is an urgent need for a new type of ash silo gasification device capable of automatically detecting and clearing clogging, ensuring long-term stable operation. Summary of the Invention

[0013] Furthermore, a flow guiding device is provided at the bottom of the connecting pipe. The flow guiding device includes a flow guiding plate, a buffer, and a vibrator.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0017] 1. Based on the design of the gasification component including a chamber, a first gasification plate, a second gasification plate, and a softening air chamber, wherein the first and second gasification plates are arranged sequentially along the airflow direction, and the second gasification plate is floatingly installed in the chamber via an elastic component, compared with the prior art, the present invention, through the airflow homogenization design of the double gasification plates and the buffering effect of the softening air chamber, enables the gasified gas to uniformly penetrate the ash material in the discharge pipe, breaking the conditions for ash material adhesion and accumulation from the source, and significantly reducing the causes of blockage; at the same time, the uniform airflow avoids the interference of detection signals caused by local pressure changes, providing a stable environment for real-time blockage detection, solving the dual pain points of frequent blockage and detection misjudgment caused by uneven airflow in traditional gasification devices, achieving the synergy of anti-blockage prediction and accurate detection, and laying the foundation for subsequent real-time blockage clearing.
[0018] 2. Based on the design of the detection unit including a signal transmitter and a signal receiver respectively installed in the softening gas chamber and the connecting pipe, and the control system being electrically connected to the vaporization component, the detection unit, and the vibration mechanism, compared with the prior art, this invention constructs a synchronous monitoring system for the gas path and signal through a through-type detection channel, solving the core problems of low efficiency and strong pressure detection lag (which easily leads to blockage expansion) of traditional manual inspection, and realizing the capture and accurate identification of blockage signals without delay; in conjunction with the closed-loop linkage of the control system, the blockage clearing action can be triggered the moment a blockage is detected, and the entire process of "blockage identification - command issuance - blockage clearing start" can be completed without manual intervention, completely solving the shortcomings of the prior art of "untimely blockage detection and slow blockage clearing response", and ensuring continuous production operation.

Through a dual unblocking mechanism of "vibration transmission and pulsed airflow", after real-time detection and confirmation of blockage, the "impact-rebound" reciprocating vibration of the second atomizing plate is used to loosen the blockage accumulation structure and form a pulsed atomized airflow to enhance the flushing force, thereby achieving rapid stripping and discharge of the blockage. At the same time, the elastic component limits the vibration amplitude to avoid structural overload, solving the pain points of "incomplete unblocking + high equipment wear" in existing unblocking technologies. It forms a closed loop with the real-time detection function, truly achieving the core invention goal of "detecting blockage as soon as it occurs and unblocking as soon as it occurs", significantly improving the efficiency of post-blockage recovery and the reliability of equipment operation.

When an element is described as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0032] See Figures 1-8A preferred embodiment of the ash silo gasification device of the present invention includes: a silo body 1, a gasification device 2, and a control system 3; the silo body 1 has a discharge pipe 11; the gasification device 2 includes an air inlet pipe 21, a gasification component 22, a detection unit 23, a vibration mechanism 24, and a connecting pipe 25; the air inlet pipe 21, the gasification component 22, the connecting pipe 25, and the discharge pipe 11 are connected sequentially along the airflow direction; the gasification component 22 includes a silo body 221, a first gasification plate 222, and a second gasification plate 223, the first gasification plate 222 and the second gasification plate 223 are sequentially arranged in the silo body 221 along the airflow direction, forming a softening air cavity 26; the second gasification plate 223 is floatingly installed in the silo body 221, and an elastic component 27 is provided in the softening air cavity 26, the two ends of the elastic component 27 being respectively connected to the... The second vaporization plate 223 and the softening air chamber 26 limit the floating amplitude of the second vaporization plate 223; the first vaporization plate 222 has a plurality of first channels 2221, and the second vaporization plate 223 has a plurality of second channels 2231; the first channels 2221, the softening air chamber 26 and the second channels 2231 are connected in sequence; the detection unit 23 includes a signal transmitter 231 and a signal receiver 232, one of which is installed in the softening air chamber and the other is installed in the connecting pipe 25; the vibration mechanism 24 is used to impact the second vaporization plate 223 to make the second vaporization plate 223 vibrate; the control system 3 is electrically connected to the vaporization component 22, the detection unit 23 and the vibration mechanism 24.
[0033] The working principle of this invention is as follows: In use, the gasification component 22 is first activated, and the gasified gas is introduced into the silo 221 through the air inlet pipe 21. After being initially diverted through the multiple first channels 2221 of the first gasification plate 222, it forms a uniform airflow that enters the softening air chamber 26. The elastic component 27 in the softening air chamber 26 restricts the floating amplitude of the second gasification plate 223, while allowing it to move slightly with the airflow pressure, so that the airflow forms a buffer fluidization effect in the air chamber. Then, after being evenly distributed again through the multiple second channels 2231 of the second gasification plate 223, it enters the connecting pipe 25, and finally acts on the ash material in the discharge pipe 11 to reduce the accumulation viscosity, realize fluidized conveying and assist the silo 1 in discharging material, and reduce the risk of blockage from the source. During device operation, the detection unit 23 works continuously. The signal transmitter 231 installed in the softening air chamber 26 and the signal receiver 232 installed in the connecting pipe 25 form a through detection channel. The signal is continuously transmitted along the path of "softening air chamber 26 → second channel 2231 → connecting pipe 25". When ash blockage occurs in the discharge pipe 11 or the connecting pipe 25, the blockage will block or interfere with the normal transmission of the detection signal. The signal receiver 232 will feed back the abnormal signal to the control system 3 in real time. The control system 3 judges the blockage by a preset threshold. After confirming the blockage, the control system 3 immediately starts the vibration mechanism 24 to apply an impact load to the floating second aeration plate 223. Since the second aeration plate 223 and the softening air chamber 26 are connected by the elastic component 27, high-frequency vibration is generated under the impact and a "impact-rebound" reciprocating vibration is formed under the restoring force of the elastic component 27. This vibration drives the second channel 2231 to vibrate synchronously to form a pulsed aeration airflow, which enhances the flushing force on the blockage. Once the blockage is cleared, the signal in the detection channel returns to normal. The control system 3 receives the feedback signal and shuts down the vibration mechanism 24, returning the device to normal gasification and discharge mode. Through the coordinated action of the gasification component 22, detection unit 23, vibration mechanism 24, and control system 3, a closed-loop control of "gasification anti-blockage - real-time detection - vibration clearing" is achieved, ensuring continuous and stable operation of the ash silo discharge process and significantly improving discharge efficiency and the reliability of anti-blockage and clearing.
[0034] Among them, the control system 3 can be a single-chip microcomputer, microcomputer or PLC; the signal transmitter 231 and the signal receiver 232 can be an infrared signal transmitter and an infrared signal receiver or an ultrasonic signal transmitter and an ultrasonic signal receiver.
[0035] Obviously, based on the design of the gasification component 22, which includes a chamber 221, a first gasification plate 222, a second gasification plate 223, and a softening air chamber 26, with the first gasification plate 222 and the second gasification plate 223 arranged sequentially along the airflow direction, and the second gasification plate 223 floatingly mounted on the chamber 221 via an elastic component 27, compared with the prior art, this invention, through the airflow homogenization design of the double gasification plates and the buffering effect of the softening air chamber 26, enables the gasified gas to uniformly penetrate the ash material in the discharge pipe 11, breaking the conditions for ash material adhesion and accumulation from the source, and significantly reducing the causes of blockage; at the same time, the uniform airflow avoids the interference of detection signals caused by local pressure changes, providing a stable environment for real-time blockage detection, solving the dual pain points of frequent blockage and misjudgment caused by uneven airflow in traditional gasification devices 2, achieving the synergy of anti-blockage prediction and accurate detection, and laying the foundation for subsequent real-time blockage clearing. Based on the design of the detection unit 23, which includes a signal transmitter 231 and a signal receiver 232 respectively installed in the softening air chamber 26 and the connecting pipe 25, and the control system 3 electrically connected to the vaporization component 22, the detection unit 23 and the vibration mechanism 24, compared with the prior art, this invention constructs a synchronous monitoring system for the air path and signal through a through-type detection channel, solving the core problems of low efficiency and strong pressure detection lag (which easily leads to blockage expansion) of traditional manual inspection, and realizing the capture and accurate identification of blockage signals without delay; in conjunction with the closed-loop linkage of the control system 3, the blockage clearing action can be triggered the moment a blockage is detected, and the entire process of "blockage identification - command issuance - blockage clearing start" can be completed without manual intervention, completely solving the shortcomings of the prior art of "untimely blockage detection and slow blockage clearing response", and ensuring continuous production operation. Based on the design of the vibration mechanism 24 cooperating with the floatingly installed second atomizing plate 223, and the elastic component 27 being connected at both ends to the second atomizing plate 223 and the softening air chamber 26 respectively, compared with the prior art, this invention addresses the shortcomings of traditional single unblocking methods (such as incomplete unblocking by compressed air cannons and easy damage to equipment by mechanical impact). Through a dual unblocking mechanism of "vibration transmission and pulsed airflow", after real-time detection and confirmation of blockage, the second atomizing plate 223 is used for "impact-rebound" reciprocating vibration, which not only loosens the blockage accumulation structure, but also forms a pulsed atomized airflow to enhance the flushing force, thereby achieving rapid stripping and discharge of the blockage. At the same time, the elastic component 27 limits the vibration amplitude to avoid structural overload, solving the pain points of "incomplete unblocking + high equipment wear" in existing unblocking technologies. It forms a closed loop with the real-time detection function, truly achieving the core invention goal of "detecting blockage as soon as it occurs, and unblocking as soon as it occurs", significantly improving the efficiency of post-blockage recovery and the reliability of equipment operation.
[0036] refer to Figure 7Preferably, in this embodiment, both the elastic component 27 and the vibration mechanism 24 are located within the softening air chamber 26; the elastic component 27 includes a compression spring 271 and an abutment frame 272, the abutment frame 272 abuts against the second vaporization plate 223, the two ends of the compression spring 271 are respectively connected to the softening air chamber 26 and the abutment frame 272, and the compression spring 271 has a tendency to drive the abutment frame 272 closer to the second vaporization plate 223. This design, with the softening air chamber 26 being a closed space housing the elastic component 27 and the vibration mechanism 24, isolates the discharge pipe 11 from erosion by ash, preventing particles from entering the gaps between components and causing blockage, significantly extending service life and reducing maintenance frequency. The abutment frame 272 ensures that the preload of the compression spring 271 is evenly transmitted to the second aeration plate 223, guaranteeing its floating stability and enhancing the amplitude of the "impact-rebound" reciprocating vibration through the preload, which, together with the vibration mechanism 24, achieves efficient blockage clearing. At the same time, the even force distribution makes the airflow homogenization effect of the second aeration plate 223 better, avoiding local fluidization dead zones. The built-in design shortens the force transmission path between the vibration mechanism 24 and the second aeration plate 223, reducing energy loss and improving vibration transmission efficiency. Furthermore, it avoids interference from external structures, does not affect the signal transmission channel of the detection unit 23, ensures the accuracy of blockage detection, and forms an efficient synergy with the control system 3.
[0037] refer to Figure 8 Preferably, in this embodiment, the abutment frame 272 is provided with a guide groove 2721, and the softening air cavity 26 is provided with a guide rail 261. The guide groove 2721 and the guide rail 261 are slidably engaged. This slidable engagement of the guide groove 2721 and the guide rail 261 strictly limits the movement direction of the abutment frame 272, ensuring that it drives the second atomizing plate 223 to float smoothly only along the airflow axis, avoiding deviation and tilting. This allows the preload of the compression spring 271 to be evenly transmitted to the entire area of the second atomizing plate 223, and the impact force of the vibration mechanism 24 to act precisely, which not only enhances the "impact-rebound" clearing effect, but also ensures the airflow homogenization performance of the second channel 2231, avoiding local fluidization dead zones. The stable guiding movement keeps the position fluctuation of the second atomizing plate 223 within a controllable range, preventing it from touching the signal transmitter 231 of the detection unit 23 due to deviation, or causing abnormal signal transmission due to changes in the internal flow field of the air cavity, ensuring the accuracy of blockage detection and providing reliable data support for the rapid response of the control system 3.
[0038] refer to Figure 7Preferably, in this embodiment, the diameter of the first channel 2221 is larger than the diameter of the second channel 2231. The larger diameter of the first channel 2221 allows for rapid diversion of the concentrated vaporized gas from the inlet pipe 21, preventing local turbulence from causing ash material disturbance and adhesion. The smaller diameter of the second channel 2231 further refines the airflow into a fine air curtain, significantly increasing the contact area with the ash material in the discharge pipe 11, forming a uniform air film to counteract particle adhesion, breaking the adhesion and accumulation conditions at the source, and reducing the causes of blockage. The design of large inlet and small outlet creates a stable pressure field within the softening air chamber 26, avoiding sudden changes in airflow pressure. This ensures the smooth floating of the second vaporization plate 223 and prevents turbulent flow from interfering with the signal transmission of the detection unit 23, ensuring error-free blockage signal identification and laying the foundation for rapid response of the control system 3. During unblocking, the small-diameter second channel 2231 can amplify the airflow pulsation caused by the vibration mechanism 24, forming a high-pressure pulse airflow. This, combined with the vibration of the second aeration plate 223, produces a dual effect of "vibration loosening + high-pressure flushing" on the blockage ash material, resulting in more thorough unblocking. At the same time, the small diameter can reduce ash backflow, protect the internal structure of the aeration component 22, and extend its service life.
[0039] refer to Figure 7Preferably, in this embodiment, the vibration mechanism 24 includes a support base 241, a horizontal linear telescopic rod 242, and a vibration generator 243. The horizontal linear telescopic rod 242 is installed at the bottom of the softening air chamber 26 and is mounted on and supported by the support base 241. The output of the horizontal linear telescopic rod 242 is connected to the vibration generator 243 to drive the vibration generator 243 to move closer to or away from the second atomizing plate 223. The control system 3 is electrically connected to the horizontal linear telescopic rod 242, the horizontal linear telescopic rod 242, and the vibration generator 243. The horizontal linear telescopic rod 242 can drive the vibration generator 243 to flexibly move closer to or away from the second atomizing plate 223. During clearing blockages, it precisely fits and transmits impact force, enhancing the "impact rebound" clearing effect. During non-clearing stages, it moves away to avoid interfering with the airflow homogenization function of the second atomizing plate 223, ensuring normal fluidization and preventing blockages, thus solving the problem that fixed vibration structures easily affect the atomization effect. The support base 241 provides stable support for the horizontal linear telescopic rod 242, preventing component displacement during vibration and ensuring that the impact force is accurately applied to the second aeration plate 223. Combined with the guide structure, it further ensures smooth movement, reduces energy loss, extends the service life of the mechanism, lowers maintenance costs, and provides support for continuous operation. The control system 3 synchronously controls all components. Upon detecting a blockage, it can quickly link the telescopic rod to advance and the vibration generator 243 to start, achieving a seamless connection between "detection and blockage clearing." After clearing the blockage, it automatically resets without manual intervention, ensuring the high efficiency of closed-loop control while avoiding mechanical interference and not affecting the signal transmission of the detection unit 23, ensuring accurate detection. The horizontal linear telescopic rod 242 can be an electric push-pull rod, a telescopic cylinder, or a hydraulic telescopic rod; the vibration generator 243 can be an eccentric rotor motor, a linear resonant actuator, or a piezoelectric ceramic vibrator 63.
[0040] refer to Figure 1 and Figure 7Preferably, in this embodiment, the connecting pipe 25 is connected to a receiving box 4, and the receiving box 4 is provided with a receiving space 41. The receiving space 41 extends upward from the connecting pipe 25 and communicates with the connecting pipe 25. A high-pressure spraying device 5 is provided in the receiving space 41. The receiving space 41 extends upward and communicates with the connecting pipe 25, so that the high-pressure spraying device 5 can be accurately aimed at the high-blockage area where the connecting pipe 25 and the discharge pipe 11 meet. The vibration of the second gasification plate 223 forms a dual unblocking effect of "vibration loosening + high-pressure flushing", which effectively breaks up stubborn accumulations and solves the blockage problem that is difficult to cure by a single unblocking method. The upwardly extending receiving structure does not occupy the main channel of the connecting pipe 25, avoids obstructing the gasification and homogenization flow, and ensures the fluidization effect during normal discharge. At the same time, the receiving box 4 forms a closed protective space to prevent ash from corroding the spraying device, extend the service life of the components, and reduce the frequency of maintenance. The high-pressure spraying device 5 is linked with the control system 3. It can be started synchronously after a blockage is detected. With the help of the positioning function of the accommodating space 41, it can accurately exert force and quickly clear the blockage. Moreover, the structural design does not interfere with the signal transmission of the detection unit 23, ensuring a seamless connection between "detection and blockage clearing", further improving the continuity and reliability of material discharge.
[0041] refer to Figure 7 Preferably, in this embodiment, the high-pressure spraying device 5 includes a lifting rod 51 and a high-pressure nozzle 52. The lifting rod 51 is installed on the top of the accommodating space 41, and the output part of the lifting rod 51 is connected to and supports the high-pressure nozzle 52. The high-pressure nozzle 52 is externally connected to a high-pressure air source and is used to spray and clean the second atomization plate 223. The high-pressure nozzle 52 specifically cleans the second atomization plate 223 and the second channel 2231, using high-pressure airflow to forcefully remove accumulated dust, avoiding airflow homogenization failure caused by channel blockage, and maintaining fluidization anti-blockage capability from the source; at the same time, the cleaned plate surface is free of dust interference, ensuring stable signal transmission of the detection unit 23 and avoiding detection misjudgment caused by dust obstruction. The lifting rod 51 can adjust the nozzle height to solve the problem of blind spots in cleaning fixed nozzles; the high-pressure air source provides strong impact force to quickly remove stubborn adhered dust, eliminating the need for manual disassembly and maintenance, and significantly reducing operation and maintenance costs. The cleaned second aeration plate 223 can transmit the impact force of the vibration mechanism 24 more efficiently, forming a "cleaning-vibration-flushing" synergistic closed loop with the pulse airflow; the structural design does not occupy the main air path, does not affect normal fluidized material discharge, and is installed in the accommodating space 41 to avoid ash corrosion, extend the service life of components, and ensure stable operation of the entire "anti-blocking-detection-unblocking" process.
[0042] refer to Figure 7Preferably, in this embodiment, a flow guiding device 6 is provided at the bottom of the connecting pipe 25. The flow guiding device 6 includes a flow guiding plate 61, a buffer 62, and a vibrator 63. The flow guiding plate 61 has a bearing end 611 and a discharge end 612. The bearing end 611 supports the bottom of the second vaporization plate, and the discharge end 612 is connected to the discharge pipe 11. The flow guiding plate 61 extends along the gas flow direction, and the horizontal height of the bearing end 611 is higher than the horizontal height of the discharge end 612. The two ends of the buffer 62 are respectively connected to the bottom wall of the flow guiding plate 61 and the connecting pipe 25. The vibrator 63 is installed at the bottom of the flow guiding plate 61, and the control system 3 is electrically connected to the vibrator 63. The inclined design of the guide plate 61 (high at the bearing end 611 and low at the discharge end 612) assists the ash material to flow towards the discharge pipe 11 with the help of gravity, reducing ash accumulation at the bottom of the connecting pipe 25. Simultaneously, it receives the airflow and ash material from the second aeration plate 223, guiding the flow field to transition smoothly along a preset direction, avoiding eddy current formation, ensuring uniform aeration, and reducing the risk of blockage from the source. The vibrator 63 is linked with the control system 3, activating synchronously upon detecting a blockage. It transmits high-frequency vibration through the guide plate 61, directly loosening the accumulated ash material at the bottom. Combined with the aeration airflow and the vibration of the second aeration plate 223, it forms a triple clearing force, effectively breaking down stubborn blockages and overcoming the limitations of single clearing methods. The buffer 62 absorbs the vibration impact, preventing damage to the connecting pipe 25 structure from the vibration of the guide plate 61, while also improving the uniformity of vibration transmission. Stable structural movement does not interfere with the signal transmission channel of the detection unit 23, ensuring error-free blockage signal identification, providing reliable support for closed-loop control, and extending the equipment's service life.
[0043] refer to Figure 1Preferably, in this embodiment, the gasification device 2 is provided in multiple units. The ash silo gasification device further includes an air chamber 7 and an air compressor 8. The air chamber 7 is divided into multiple unit air chambers 71, and each unit air chamber 71 is connected to the air inlet pipe 21 of one of the gasification devices 2 through a flange 802. Each unit air chamber 71 is connected to the air compressor 8 through an air supply pipe 801, and each air supply pipe 801 is equipped with a flow control valve 803. The control system 3 is electrically connected to the air compressor 8 and the flow control valve 803. Multiple gasification devices 2, in conjunction with the unit air chambers 71, achieve full coverage of the discharge pipe 11, avoiding fluidization dead zones in single gasification. The flow control valve 803 is linked with the control system 3 and can accurately adjust the air supply volume of the corresponding area according to the detection signal, increase the airflow intensity for easily blocked areas, reduce the risk of local accumulation from the source, and ensure fluidization uniformity. The unit gas chamber 71 is independently supplied with gas, so the failure of a single gasification device 2 or gas chamber does not affect the operation of the overall system, avoiding downtime losses. During unblocking, the corresponding area gasification device 2 can be activated simultaneously or selectively, forming a multi-dimensional unblocking force in conjunction with vibration and spraying, significantly improving the efficiency of clearing stubborn blockages. The flow rate of each gas supply pipe 801 can be adjusted as needed to avoid energy waste caused by ineffective gas supply. The flange connection method 802 simplifies the installation and maintenance process, and with the automated control system 3, it reduces manual intervention and lowers operation and maintenance costs. The combination of unified gas source and zoned control balances gas supply stability and adjustment flexibility, extending the overall service life of the equipment. The buffer 62 can be a buffer spring or a hydraulic damper.
[0044] refer to Figure 2 and Figure 6 Preferably, in this embodiment, the air inlet pipe 21 is equipped with a one-way valve 9. This configuration prevents ash or backflow gas from the discharge pipe 11 from entering the air inlet pipe 21, avoiding airway blockage and wear on components such as the air compressor 8, ensuring a stable supply of gasified gas; it also prevents airflow backflow from causing airway pressure fluctuations, avoiding interference with the signal transmission of the detection unit 23, ensuring accurate blockage identification, and providing reliable support for closed-loop control; when multiple gasification devices 2 operate in parallel, it avoids airflow crosstalk between unit air chambers 71, and, in conjunction with the flow control valve 803, achieves precise zoned air supply, ensuring efficient and coordinated anti-blockage and unblocking, and extending the overall service life of the equipment.
