Abstract

The invention discloses an anti-blocking method, device and equipment for a fly ash conveying slope elephant trunk and a storage medium. According to the method, a vibrator is installed on the slope elephant trunk, and a gravity sensor is installed on each loading bucket of a bucket elevator so as to detect loading ash weight data after the loading buckets move to an ash loading position; the anti-blocking control module drives the vibrator to vibrate the pipe wall of the slope elephant trunk based on the ash loading weight data measured by the gravity sensors when a plurality of continuous ash loading weight data smaller than an ash loading weight threshold value exist. Therefore, due to the fact that the hopper of the bucket elevator is continuously loaded with ash at the output end of the slope articulated chute, when no fly ash is output at the output end of the slope articulated chute, it can be monitored that the weight of the hopper of the bucket elevator is abnormally low, and after a plurality of continuous abnormally-low weights of the hopper are monitored, it can be confirmed that the slope articulated chute is blocked by the fly ash; and therefore, the slope chute is dredged, smooth and safe operation of the system is guaranteed, and the production continuity is guaranteed.

Description

[0002] In fields such as waste incineration power generation and coal-fired power plants, the fly ash generated from incineration needs to be transported and temporarily stored through a fixed process. The conventional process is to collect the fly ash through a public scraper conveyor, then transport it to a bucket elevator via an inclined chute, and finally send it to the fly ash storage silo for temporary storage. This transportation method is the fly ash treatment mode widely used in the industry at present.

[0003] Fly ash inherently has the characteristics of fine particles, poor flowability, and susceptibility to moisture and caking. However, the flow area of ​​the inclined chute in the existing conveying system is generally small. Under conditions of high fly ash humidity or low temperature, fly ash bridging and wall adhesion are very likely to occur in the inclined chute section, resulting in poor conveying or even complete blockage. This not only requires frequent manual dredging and cleaning, which seriously affects the continuity of production, but also poses certain safety risks.

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] The proposed solution can be implemented using a terminal with data processing capabilities, which can be an anti-clogging control module of a fly ash conveying system. The fly ash anti-clogging system may further include a ramp-feeding module.

[0052] Specifically, such as Figure 1 As shown, the inclined ash conveying module includes a scraper conveyor, an inclined chute, and a bucket elevator.

[0053] The scraper conveyor is connected to the bucket elevator via an inclined chute. The inclined chute is equipped with a vibrator, which can be connected to an anti-clogging control module. Specifically, the vibrator can be installed on the outer wall of the bottom of the inclined chute. When the anti-clogging control module drives the vibrator to vibrate the wall of the inclined chute, it causes the fly ash adhering to the inner wall of the inclined chute to detach, breaking up fly ash bridging within the inclined chute. The bucket elevator can contain multiple buckets, which circulate to load fly ash from the output end of the inclined chute and pour the loaded fly ash into a fly ash storage bin. Each bucket is equipped with a gravity sensor, which can communicate with the anti-clogging control module. After the bucket moves to the loading position at the output end of the inclined chute to load fly ash, the gravity sensor can transmit the monitored fly ash weight data to the anti-clogging control module.

[0054] Next, combined Figure 2 The method for preventing blockage of the fly ash conveying inclined chute of this application may include the following steps:

[0055] Step S110: Based on the ash weight data measured by each gravity sensor, construct the ash weight time series.

[0056] It is understandable that the ash loading weight data represents the weight of fly ash collected by the hopper at the loading position. If the inclined chute is unblocked and outputs fly ash normally, the fly ash weight collected by the hopper at the loading position is a normal value, such as the fly ash weight corresponding to the hopper's rated capacity. If the inclined chute is slightly blocked but ash output is normal, the fly ash weight collected by the hopper at the loading position is also normal. If the inclined chute is severely blocked, the ash output is significantly reduced, and the fly ash weight collected by the hopper at the loading position is far below the rated value. If the inclined chute is completely blocked and no ash is output, then the hopper does not collect any ash at the loading position, and its uploaded ash loading weight data is 0. Therefore, the ash loading weight time series can dynamically reflect the fly ash blockage status of the inclined chute.

[0057] Step S120: When there are multiple consecutive ash weight data in the ash weight time sequence that are all less than the ash weight threshold, drive the vibrator to vibrate the wall of the inclined chute.

[0058] The ash loading weight threshold represents the minimum weight of fly ash that can be loaded into the hopper when the inclined chute is severely blocked. Therefore, if the ash loading weight data is less than the ash loading weight threshold, it indicates that the fly ash blockage in the inclined chute is at least severe.

[0059] Understandably, a ash weight reading less than the ash weight threshold indicates at least severe ash blockage in the inclined chute. However, considering the randomness of the ash loading process (e.g., when the inclined chute is normally unblocked, occasional mechanical deviations in the hopper or the shape distribution of fly ash at the chute's output end may prevent the hopper from reaching the acceptable level), it's necessary to analyze the ash weight data from both the preceding and following hoppers. If the current ash weight reading is less than the threshold, and the ash weight readings from the hoppers before and after it are also less than the threshold, it indicates that the inclined chute has not had sufficient fly ash output for an extended period. This confirms the presence of fly ash blockage within the inclined chute, allowing the vibrator to be activated to vibrate the chute's wall.

[0060] The anti-clogging method for the fly ash conveying inclined chute provided in this embodiment involves installing a vibrator on the inclined chute and a gravity sensor on each bucket of the bucket elevator to detect the ash weight data after moving to the ash loading position. The vibrator and each gravity sensor are communicatively connected to the anti-clogging control module. Based on the ash weight data measured by each gravity sensor, the anti-clogging control module constructs an ash weight time sequence. When multiple consecutive ash weight data points in the ash weight time sequence are all less than the ash weight threshold, the vibrator is driven to vibrate the wall of the inclined chute. Therefore, since the bucket elevator continuously loads ash at the output end of the inclined chute, when there is no fly ash output at the inclined chute output end, an abnormally low bucket weight can be monitored. After monitoring multiple consecutive abnormally low bucket weights, fly ash blockage in the inclined chute can be confirmed, which then feeds back to the vibrator to strike the wall of the inclined chute to clear the blockage, ensuring smooth and safe system operation and maintaining production continuity.

[0061] In some embodiments of this application, the inclined ash conveying module mentioned in the foregoing embodiments is further described. For details, please refer to... Figure 1 A scraper conveyor includes a front scraper conveyor and a rear scraper conveyor.

[0062] The inclined chute has two sections, including a first inclined chute and a second inclined chute. Correspondingly, the rapper includes a first rapper and a second rapper.

[0063] Specifically, the front-stage scraper conveyor and the rear-stage scraper conveyor are connected via a first inclined chute. The rear-stage scraper conveyor is connected to the bucket elevator via a second inclined chute. The first inclined chute is equipped with a first vibrator, and the second inclined chute is equipped with a second vibrator.

[0064] It is understandable that, as in the aforementioned embodiment, when there are multiple consecutive ash weight data in the ash weight time sequence that are all less than the ash weight threshold, the wall of the inclined chute needs to be vibrated. That is, the first vibrator knocks on the wall of the first inclined chute, and the second vibrator knocks on the wall of the second inclined chute.

[0065] Based on this, to more accurately determine whether fly ash blockage occurs in the first inclined chute, the second inclined chute, or both inclined chute sections, and to specifically target the chute sections requiring clearing with vibration while minimizing damage to those sections that do not require vibration, this embodiment can analyze whether fly ash blockage has occurred in the inclined chute based on the motor current when the scraper conveyor is carrying fly ash. The specific process may include:

[0066] S1. Real-time acquisition of the first motor current of the upstream scraper conveyor carrying fly ash, and the second motor current of the downstream scraper conveyor carrying fly ash.

[0067] It is understandable that when the scraper conveyor is unloaded, its work is minimal, and the motor current is at its minimum under a constant operating voltage. When the scraper conveyor is loaded, its work is greater than when unloaded, and fluctuates with the amount of fly ash in the load. Therefore, under a constant operating voltage, the motor current is greater than when unloaded and also fluctuates with the amount of fly ash in the load. Thus, the magnitude of the scraper conveyor motor current can be used to indicate the amount of fly ash carried by the scraper conveyor during operation.

[0068] S2. If the current of the first motor is greater than the upper limit of the normal load current range and the current of the second motor is less than the lower limit of the normal load current range, then the first vibrator is driven to vibrate the first inclined chute.

[0069] Specifically, the normal load current range can be a current range consisting of a fixed upper current limit and a fixed lower current limit, or it can be a normal current range determined based on the load current during the running period after the scraper conveyor has been running for a period of time and has stabilized.

[0070] It is understandable that since the current of the scraper conveyor motor can be used to indicate the amount of fly ash carried by the scraper conveyor during operation, if the current of the first motor is greater than the upper limit of the normal load current range, it can indicate that the upstream scraper conveyor is carrying an excessive amount of fly ash. If the current of the second motor is less than the lower limit of the normal load current range, it can indicate that the downstream scraper conveyor is carrying only a small amount of fly ash. This can indicate that the fly ash of the upstream scraper conveyor is blocked in the first inclined chute. The first inclined chute outputs a small amount or no fly ash to the downstream scraper conveyor, so the first vibrator can be driven to vibrate the first inclined chute.

[0071] S3. If the current of the second motor is greater than the upper limit of the normal load current range, and there are multiple consecutive ash weight data in the ash weight time sequence that are all less than the ash weight threshold, then drive the second vibrator to vibrate the second inclined chute.

[0072] It is understandable that if the current of the second motor is greater than the upper limit of the normal load current range, it indicates that the downstream scraper conveyor is carrying an excessive amount of fly ash, and the bucket cannot transport fly ash of the required weight. This indicates that the fly ash of the downstream scraper conveyor is blocked in the second inclined chute, causing the second inclined chute to output a small amount or no fly ash to the output end. In this case, the second vibrator can be driven to vibrate the second inclined chute.

[0073] In order to further improve the effectiveness of unblocking the inclined chute, in some embodiments of this application, a fan can be installed inside the inclined chute mentioned in the foregoing embodiments. Based on this, the fan can be driven to work while the vibrator is vibrating the wall of the inclined chute.

[0074] Understandably, installing a fan inside the inclined chute and operating it synchronously with the vibrator creates a dual anti-clogging mechanism of vibration and airflow. The vibrator uses external force to shake off fly ash adhering to the pipe wall, while the airflow generated by the fan simultaneously blows away the fly ash deposited inside the inclined chute, promptly removing any fine, damp fly ash that hasn't completely detached after vibration, preventing it from re-adhering to the wall or bridging. This enhances the conveying force for fly ash with poor flowability, further reducing the risk of clogging, decreasing the frequency of manual unclogging, and more efficiently ensuring the continuity of fly ash conveying. Combined with the original widened chute structure, this improves the system's anti-clogging reliability.

[0075] To improve the controllability of unblocking the inclined chute, some embodiments of this application may include command control for the vibration of the inclined chute, so that the anti-blocking scheme for the fly ash conveying inclined chute may further include:

[0076] In response to the control command of the vibrator, drive the vibrator to perform actions.

[0077] Specifically, the vibrator's vibration action can be integrated into the vibrator control switch of the anti-blocking control module. This allows monitoring personnel to press the vibrator control switch when it is necessary to vibrate the inclined chute. The anti-blocking control module responds to the vibrator's control command and drives the vibrator to perform the action, thereby achieving the effect of vibrating the inclined chute.

[0078] In some embodiments of this application, the above-mentioned inclined chute is further described. Specifically, the width of the inclined chute can be greater than the width of the basic inclined chute.

[0079] Understandably, increasing the width of the original inclined chute increases the flow area of ​​the inclined chute, reduces the frictional resistance and wall effect of fly ash flow, and fundamentally reduces the physical basis for fly ash bridging and adhesion in the inclined section. This modification optimizes the conveying path from the perspective of fluid mechanics and realizes the smooth gravity flow of fly ash.

[0080] Specifically, the original DN300 inner diameter chute can be replaced with a DN400 inner diameter chute, increasing the flow area by approximately 78%.

[0081] In addition, the outer shell of the inclined chute can be made of wear-resistant steel, specifically 16Mn wear-resistant steel plate, to extend its service life. A mounting base is welded to the middle of the chute shell for mounting a rapper.
