Description
Technical Field
[0001] This invention relates to the technical field of stacker-reclaimers, and specifically to a dust removal method, apparatus, medium, equipment, and system for stacker-reclaimers. Background Technology
[0002] A stacker-reclaimer is a high-efficiency loading and unloading machine used in large dry bulk cargo yards for continuous conveying and reclaiming of materials. It mainly consists of a boom that can tilt and swing horizontally, and its front end bucket wheel, belt, hydraulic cylinder, and running mechanism.
[0003] Current stacker-reclaimers cannot achieve precise dust removal, mainly because they are manually turned on and off, and cannot be adjusted according to the actual situation on site. They consume a lot of water and electricity, and sometimes forgetting to turn them off manually often leads to pump damage.
[0004] Accordingly, there is a need in the art to provide a method for automatic and precise dust removal applied to stacker-reclaimers. Summary of the Invention
[0005] The present invention aims to solve the above-mentioned problems in the prior art, namely, that existing stacker-reclaimers cannot achieve automatic and accurate dust removal.
[0006] In a first aspect, the present invention provides a dust removal method for a stacker-reclaimer, the method comprising the following steps:
[0007] Obtain the flow rate information of the stacker-reclaimer and the particulate matter concentration information at the dust removal point on the stacker-reclaimer;
[0008] Determine whether the dust removal point needs dust removal based on the flow rate information and the particulate matter concentration information;
[0009] If dust removal is required at the dust removal point, dust removal shall be performed at the dust removal point;
[0010] During the dust removal process, the decision to stop dust removal is made based on the flow rate information and / or the particulate matter concentration information.
[0011] Preferably, determining whether the dust removal point needs dust removal based on the flow rate information and the particulate matter concentration information includes:
[0012] If the flow rate information is greater than or equal to the first flow rate threshold and the particulate matter concentration information is greater than or equal to the first concentration threshold, then dust removal is required; otherwise, dust removal is not required.
[0013] Preferably, the dust removal at the dust removal point includes:
[0014] Control the start of the air compressor system to generate aerosol for dust suppression;
[0015] Control the nozzles at the dust removal point to spray air mist to suppress dust; the nozzles are connected to the air compressor system.
[0016] Preferably, controlling the nozzles at the dust removal point to spray aerosol for dust suppression includes:
[0017] The control unit starts the aerosol pump, which is connected to the air compressor system. The aerosol pump delivers the aerosol generated by the air compressor system to the nozzle for spraying.
[0018] Preferably, the step of determining whether to stop dust removal based on the flow rate information and / or the particulate matter concentration information includes:
[0019] Dust removal is stopped when the flow rate information is less than the second flow rate threshold.
[0020] Preferably, the step of determining whether to stop dust removal based on the flow rate information and / or the particulate matter concentration information includes:
[0021] Dust removal is stopped when the flow rate information is less than the second flow rate threshold and the particulate matter concentration information is less than the second concentration threshold.
[0022] In a second aspect, the present invention provides a dust removal device for a stacker-reclaimer, comprising:
[0023] A dust removal device for a stacker-reclaimer, characterized in that it comprises:
[0024] The information acquisition unit is used to acquire the flow rate information of the stacker-reclaimer and the particulate matter concentration information at the dust removal point set on the stacker-reclaimer;
[0025] A dust removal judgment unit is used to determine whether the dust removal point needs dust removal based on the flow rate information and the particulate matter concentration information.
[0026] A dust removal unit is used to remove dust at the dust removal point if dust removal is required.
[0027] The stop unit is used to determine whether to stop dust removal during the dust removal process based on the flow rate information and / or particulate matter concentration information.
[0028] Thirdly, the present invention provides a storage medium storing a program that, when executed by a processor, implements the method described in the first aspect.
[0029] Fourthly, the present invention provides an electronic device, comprising: a memory and a processor communicatively connected to the memory, the memory storing a program, and the processor executing the program to implement the method as described in the first aspect.
[0030] Fifthly, the present invention provides a dust removal system for a stacker-reclaimer, comprising:
[0031] The information acquisition unit includes a flow sensor for collecting flow information of the stacker-reclaimer and a PM particulate matter detection sensor installed at the dust removal point on the stacker-reclaimer for collecting particulate matter concentration information.
[0032] Air compressor system, used to generate air mist for dust suppression;
[0033] A nozzle is disposed at the dust removal point and connected to the air compressor system;
[0034] An aerosol pump, which is connected to both the air compressor system and the nozzle, is used to drive the aerosol to be sprayed out of the designated nozzle;
[0035] The electronic device described in the fourth aspect is connected to the information acquisition unit, the air compressor system, the aerosol pump, and the nozzle.
[0036] Through the above technical solution, the present invention has the following beneficial effects:
[0037] The system determines whether dust removal is needed by detecting the particulate matter concentration at the dust removal point, and determines whether the stacker-reclaimer is currently operating by using the flow information in the stacker-reclaimer. This avoids misjudgments caused by dust generated by adjacent equipment drifting to the dust removal point. Dust removal is only performed when the particulate matter concentration at the dust removal point exceeds the standard during normal operation of the stacker-reclaimer, thus achieving precise dust removal.
[0038] During the dust removal process, the flow rate information of the stacker-reclaimer is used to determine whether the stacker-reclaimer is performing stacking and reclaiming work. If the stacker-reclaimer is not performing stacking and reclaiming work, the dust removal is automatically stopped, thus realizing the automation of dust removal, reducing the use of manual labor, and reducing environmental pollution caused by workers forgetting to turn on the dust removal system and the waste of electricity and water resources caused by workers forgetting to turn off the dust removal system.

[0041] Figure 3 This is a schematic diagram of the main structure of the stacker-reclaimer dust removal system provided in this embodiment. Detailed Implementation
[0042] The present disclosure will be further described below with reference to the embodiments shown in the accompanying drawings.
[0043] Reference Figure 1In a first aspect, the present invention provides a dust removal method for a stacker-reclaimer, the method comprising the following steps:
[0044] S1. Obtain the flow rate information of the stacker-reclaimer and the particulate matter concentration information at the dust removal points on the stacker-reclaimer;
[0045] S2. Determine whether dust removal points need to be removed based on flow rate and particulate matter concentration information;
[0046] S3. If dust removal is required at the dust removal point, spray aerosol to suppress dust at the dust removal point;
[0047] S4. During the dust removal process, determine whether to stop the dust removal based on the flow rate information and / or particulate matter concentration information.
[0048] It should be noted that the flow rate information of the stacker-reclaimer can be obtained through the array belt scale of the stacker-reclaimer or through the pressure sensor within the stacker-reclaimer. The method of obtaining the flow rate information depends on the structure of the stacker-reclaimer, and those skilled in the art can adjust the method of obtaining the flow rate information according to the specific structure of the stacker-reclaimer. The particulate matter concentration information at the dust collection points can be obtained through PM particulate matter detection sensors installed at the dust collection points. Multiple dust collection points are set up, and each dust collection point is equipped with a PM particulate matter detection sensor.
[0049] In a preferred embodiment, determining whether a dust removal point needs dust removal based on flow rate information and particulate matter concentration information includes: if the flow rate information is greater than or equal to a first flow rate threshold and the particulate matter concentration information is greater than or equal to a first concentration threshold, then dust removal is required; otherwise, dust removal is not required.
[0050] If the flow rate is not greater than the first flow rate threshold, it indicates that the stacker-reclaimer is not working properly and is not performing normal stacking and reclaiming. In this case, if the particulate matter concentration at the dust removal point exceeds the standard, it may be due to dust diffusion from other nearby equipment. When both the flow rate and particulate matter concentration reach the first flow rate threshold and the first concentration threshold, it indicates that the dust at the dust removal point is caused by the operation of the stacker-reclaimer and dust removal is required. Otherwise, dust removal is not necessary. This technical solution improves the accuracy of determining whether dust removal is needed and reduces the waste of electricity and water resources caused by misjudgments.
[0051] Reference Figure 2 In a preferred embodiment, step S3, spraying aerosol dust suppression at the dust collection point specifically includes the following steps:
[0052] S31. Control the start of the air compressor system and mist pump to generate mist for dust suppression;
[0053] S32. Control the nozzles at the dust removal point to spray aerosol to suppress dust.
[0054] The air compressor system generates aerosol, which is used for dust suppression. The air compressor system is connected to nozzles via pipelines. The aerosol pump delivers the aerosol through the pipelines to the nozzles at the dust suppression points and sprays it out. Multiple dust suppression points and multiple nozzles are installed, with one nozzle near each dust suppression point. When the particulate matter concentration at a dust suppression point exceeds the standard and the stacker-reclaimer's flow rate reaches the first flow threshold, the air compressor system is activated to generate aerosol for dust suppression. The aerosol pump then pumps the aerosol through the pipelines to the nozzles at the dust suppression points, opening the nozzles and spraying the aerosol out.
[0055] It should be noted that the aerosol pump can be a multi-stage vertical pump or a horizontal pump. Those skilled in the art can use other types of aerosol pumps depending on the actual situation, as long as they can pump the aerosol from the pipeline to the nozzle.
[0056] In a preferred embodiment, step S4, determining whether to stop dust removal based on flow rate information and / or particulate matter concentration information, includes:
[0057] When the flow rate is less than the second flow rate threshold, dust removal stops. When the flow rate is less than the second flow rate threshold, it indicates that the stacker-reclaimer has stopped working or has stopped stacking and reclaiming materials. At this time, the stacker-reclaimer no longer generates dust, and dust removal is not required. Automatically stopping dust removal at this point avoids waste of electricity and water resources caused by operators forgetting to turn it off.
[0058] Alternatively, dust removal can be stopped when the particulate matter concentration is below the second concentration threshold. If the particulate matter concentration at the dust removal point is detected to be below the second concentration threshold, it indicates that there is not a large amount of dust at the dust removal point, and dust removal is not required.
[0059] Alternatively, dust removal can be stopped when both the flow rate and particulate matter concentration are below the second flow rate threshold and the concentration is below the second concentration threshold. When the flow rate is below the second flow rate threshold, it indicates that the stacker-reclaimer has stopped working or has stopped stacking / reclaiming operations; no dust is generated at this point, but dust removal continues. When the particulate matter concentration is below the second concentration threshold, it indicates that the particulate matter concentration at the dust removal point is low, and dust removal is no longer necessary; therefore, dust removal should be stopped. Continuing dust removal after the stacker-reclaimer has stopped working or has stopped stacking / reclaiming operations can effectively remove residual dust at the dust removal point, thus improving the dust removal efficiency.
[0060] In one preferred embodiment, this embodiment provides a dust removal method for a stacker-reclaimer, the method comprising the following steps:
[0061] S1. Obtain the flow rate information of the stacker-reclaimer and the particulate matter concentration information set at the dust removal points on the stacker-reclaimer;
[0062] Flow rate information of the stacker-reclaimer can be obtained through the array belt scale of the stacker-reclaimer or through the pressure sensor within the stacker-reclaimer. The method of obtaining the flow rate information depends on the structure of the stacker-reclaimer, and those skilled in the art can adjust the method of obtaining the flow rate information according to the specific structure of the stacker-reclaimer. Particulate matter concentration information at dust collection points can be obtained through PM particulate matter detection sensors installed at the dust collection points. Multiple dust collection points are set up, and each dust collection point is equipped with a PM particulate matter detection sensor.
[0063] S2. Determine whether dust removal points need to be removed based on flow rate and particulate matter concentration information;
[0064] If the flow rate information is greater than or equal to the first flow rate threshold and the particulate matter concentration information is greater than or equal to the first concentration threshold, then dust removal is required; otherwise, dust removal is not required.
[0065] If the flow rate is not greater than the first flow rate threshold, it indicates that the stacker-reclaimer is not working properly and is not performing normal stacking and reclaiming. In this case, if the particulate matter concentration at the dust removal point exceeds the standard, it may be due to dust diffusion from other nearby equipment. When both the flow rate and particulate matter concentration reach the first flow rate threshold and the first concentration threshold, it indicates that the dust at the dust removal point is caused by the operation of the stacker-reclaimer and dust removal is required. Otherwise, dust removal is not necessary. This technical solution improves the accuracy of determining whether dust removal is needed and reduces the waste of electricity and water resources caused by misjudgments.
[0066] S3. If dust removal is required at the dust removal point, spray aerosol to suppress dust at the dust removal point;
[0067] Spraying aerosol dust suppression at dust collection points specifically includes:
[0068] S31. Control the start of the air compressor system and mist pump to generate mist for dust suppression;
[0069] S32. Control the nozzles at the dust removal point to spray aerosol to suppress dust.
[0070] The air compressor system generates aerosol, which is used for dust suppression. The air compressor system is connected to nozzles via pipelines. The aerosol pump delivers the aerosol through the pipelines to the nozzles at the dust suppression points and sprays it out. Multiple dust suppression points and multiple nozzles are installed, with one nozzle near each dust suppression point. When the particulate matter concentration at a dust suppression point exceeds the standard and the stacker-reclaimer's flow rate reaches the first flow threshold, the air compressor system is activated to generate aerosol for dust suppression. The aerosol pump then pumps the aerosol through the pipelines to the nozzles at the dust suppression points, opening the nozzles and spraying the aerosol out.
[0071] It should be noted that the aerosol pump can be a multi-stage vertical pump or a horizontal pump. Those skilled in the art can use other types of aerosol pumps depending on the actual situation, as long as they can pump the aerosol from the pipeline to the nozzle.
[0072] Step S4. During the dust removal process, determine whether to stop the dust removal based on the flow rate information and / or particulate matter concentration information.
[0073] When the flow rate is less than the second flow rate threshold, dust removal stops. When the flow rate is less than the second flow rate threshold, it indicates that the stacker-reclaimer has stopped working or has stopped stacking and reclaiming materials. At this time, the stacker-reclaimer no longer generates dust, and dust removal is not required. Automatically stopping dust removal at this point avoids waste of electricity and water resources caused by operators forgetting to turn it off.
[0074] Alternatively, dust removal can be stopped when the particulate matter concentration is below the second concentration threshold. If the particulate matter concentration at the dust removal point is detected to be below the second concentration threshold, it indicates that there is not a large amount of dust at the dust removal point, and dust removal is not required.
[0075] Alternatively, dust removal can be stopped when both the flow rate and particulate matter concentration are below the second flow rate threshold and the concentration is below the second concentration threshold. When the flow rate is below the second flow rate threshold, it indicates that the stacker-reclaimer has stopped working or has stopped stacking / reclaiming operations; no dust is generated at this point, but dust removal continues. When the particulate matter concentration is below the second concentration threshold, it indicates that the particulate matter concentration at the dust removal point is low, and dust removal is no longer necessary; therefore, dust removal should be stopped. Continuing dust removal after the stacker-reclaimer has stopped working or has stopped stacking / reclaiming operations can effectively remove residual dust at the dust removal point, thus improving the dust removal efficiency.
[0076] Secondly, this embodiment provides a dust removal device for a stacker-reclaimer, comprising:
[0077] The information acquisition unit is used to acquire the flow rate information of the stacker-reclaimer and the particulate matter concentration information set at the dust removal points on the stacker-reclaimer;
[0078] The dust removal judgment unit is used to determine whether dust removal points need to be removed based on flow rate information and particulate matter concentration information.
[0079] The dust removal unit is used to spray aerosol to suppress dust at the dust removal points if dust removal is required.
[0080] The stop unit is used to determine whether to stop dust removal during the dust removal process based on flow rate information and / or particulate matter concentration information.
[0081] Thirdly, this embodiment provides a storage medium storing a program that, when executed by a processor, implements the method described in the first or second aspect.
[0082] Fourthly, this embodiment provides an electronic device, including: a memory and a processor communicatively connected to the memory, the memory storing a program, and the processor executing the program to implement the method described in the first or second aspect.
[0083] Fifthly, refer to Figure 3 This embodiment provides a dust removal system for a stacker-reclaimer, the system comprising:

[0088] For example, in the fourth aspect, electronic devices are connected to information acquisition units, air compressor systems, aerosol pumps, and nozzles.
[0089] It should be noted that the flow sensor can be an array-type belt scale installed in the stacker-reclaimer, and the information acquisition unit obtains the real-time flow information of the stacker-reclaimer through the array-type belt scale; alternatively, the flow sensor can be a pressure sensor installed below the conveyor belt of the stacker-reclaimer, and the real-time flow information of the stacker-reclaimer is obtained through the pressure data fed back by the pressure sensor. This embodiment does not limit the specific form of the flow sensor, and those skilled in the art can use other types of sensors or hardware to obtain the flow information of the stacker-reclaimer.
