Description

Technical Field

[0001] The present invention relates to the technical field of coal mine mining, and specifically to a modification system for the rear chute of a coal mine scraper loader. Background Art

[0002] During the coal mine mining process, when the scraper loader in the coal mine roadway head is used to load gangue, the gangue is discharged through the rear belt conveyor. However, the height from the rear chute of the scraper loader to the belt conveyor is generally between 0.6 and 0.8 m. When loading gangue, the gangue is likely to fall again from the running belt conveyor, and when a large amount of gangue falls from the rear chute, a large amount of coal dust will be raised, which has a greater impact on various equipment and the working environment of the staff inside the coal mine. Therefore, a dust removal spray device is often installed on the rear chute of the scraper loader. However, the current dust removal spray device cannot perform efficient dust removal spraying according to the actual amount of coal dust and dust raised by the gangue.

[0003] In view of this, a dust removal system is designed to solve the problem of coal dust and dust being raised when the gangue falls at the rear chute of the scraper loader. Summary of the Invention

[0007] The control module includes: a first control mode and a second control mode;

[0008] The first control mode controls the dust reduction process of the dust reduction component based on the generation amount of the gangue. In the first control mode, the operating parameters of the dust reduction component operate according to the first parameters;

[0009] After the second control mode runs for T time based on the first control mode, it adjusts the first parameters of the dust reduction component at the rear chute according to the dust concentration in the environment where the rear chute is currently located. If the dust concentration in the environment where the rear chute is currently located is within the preset parameters, the first parameters are optimized. If the dust concentration in the environment where the rear chute is currently located exceeds the preset parameters, the first parameters are regulated until the dust concentration detected after the dust reduction component operates for T time with the adjusted first parameters is within the preset parameters;

[0010] The control module further includes: a management and control module for controlling the energy consumption of coal mining equipment; wherein, after the management and control module adjusts the energy consumption of the coal mining equipment, based on the measured dust concentration of the current environment where the rear chute is located, the first parameter of the corresponding equipment at the rear chute is further adjusted, and finally the environmental dust concentration at the rear chute is controlled.

[0016] Further, the dust reduction component includes: a water pipe, a solenoid valve, a booster valve and a nozzle.

[0017] The water pipe is arranged along the circumference of the material leakage opening on the rear chute.

[0018] The nozzles are evenly arranged at intervals on the water pipe, and the nozzles are arranged obliquely downward.

[0019] The solenoid valve and the booster valve are both installed on the water pipe, and both the solenoid valve and the booster valve are connected to an external controller. When the dust reduction component is started, the water in the water pipe first passes through the solenoid valve and then sprays out from the nozzles.

[0020] Further, the control module includes: a data acquisition unit, a data analysis unit and a storage unit respectively connected to an external controller.

[0021] The data acquisition unit is used to collect the water flow velocity, water flow rate, pressure value of the booster valve, and dust concentration in the environment where the current rear chute is located, and send the collected data to the analysis unit and the storage unit;

[0022] The data analysis unit is communicatively connected to the data storage unit. The preset parameters are set in the data analysis unit. The preset parameters are used to compare with the data sent by the data analysis unit, and send the comparison result to the external link controller. Based on the comparison result, different signals are sent. The external link controller determines whether to start the second control mode based on the received signal;

[0023] The first control mode and the second control mode are stored in the storage unit;

[0024] An early warning module is set in the analysis unit. The early warning module is connected to the external link controller. The early warning module is used to receive the signal sent by the external link controller and give an alarm;

[0025] Among them, if the dust concentration in the environment where the current rear chute is located exceeds the preset parameter, the analysis unit sends a first signal to the external link controller. When the external link controller receives the first signal, it sends an alarm signal to the early warning module. At this time, the early warning module gives an alarm prompt.

[0026] Further, the first parameter is used to set the water flow velocity and water flow rate according to manual experience.

Each storage area stores various data of the dust reduction component corresponding to the dust concentration detected within a preset parameter range after running for T time in the first control mode. After the analysis unit performs data comparison, if the comparison result is within the preset parameter range, the analysis unit sends a second signal to the external connection controller. After receiving the second signal, the external connection controller calls the data in the corresponding storage area and optimizes the first parameter by selecting any data in the corresponding storage area as a reference.

[0032] If the comparison result exceeds the preset parameter range, the analysis unit sends a first signal to the external connection controller. After receiving the first signal, the external connection controller calls the data in the corresponding storage area and adjusts the first parameter by selecting the average value of the data in the corresponding storage area as a reference.

[0033] Further, when the comparison result is within the preset parameter range and meets the standard for ensuring dust reduction, the external connection controller can lower the operating parameters of each device of the dust reduction component, and the lowering range is based on the parameter range formed by the maximum or minimum value and the average value in each storage area.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figure 1-2 , the present invention provides a modified system for the rear chute of a coal mine scraper loader, including: an anti-spray component 3, the anti-spray component 3 is connected to the rear chute 1, located between the conveyor 2 and the rear chute 1, and is used for dust reduction treatment of the dust generated by the movement of gangue;

[0042] The anti-spray component 3 includes: a guard plate and a buffer layer;

[0043] The guard plates are arranged on both opposite sides of the bottom of the rear chute 1, the guard plates extend towards the conveyor, and there is a gap between the guard plates and the conveyor;

[0044] The buffer layers are arranged on the inner side surfaces of the guard plates, the buffer layers are elastic rubber pads, and a plurality of buffer protrusions are arranged on the surfaces of the buffer layers;

[0045] Among them, when the gangue falls, the buffer layer made of waste tires can prevent the gangue from falling from both sides of the conveyor, and at the same time can effectively buffer the falling gangue, thereby reducing the impact force of the gangue on the conveyor;

[0046] A dust reduction component 4, the dust reduction component 4 is connected to the rear chute 1 and is used for spraying water mist on the dust generated by the movement of gangue;

[0047] A control module, the control module is signal-connected to the dust reduction component 4, and the control module controls the working state of the dust reduction component 4 based on the dust concentration in the environment where the rear chute 1 is currently located;

[0048] The dust reduction component 4 includes: a water pipe, a solenoid valve, a booster valve and a nozzle;

[0049] The water pipe is arranged along the circumference of the material leakage opening on the rear chute 1;

[0050] The nozzles are evenly arranged at intervals on the water pipe, and the nozzles are arranged obliquely downward;

[0051] The solenoid valve and the booster valve are both installed on the water pipe. The solenoid valve and the booster valve are both connected to an external controller. When the dust reduction assembly 4 is started, the water in the water pipe first passes through the solenoid valve and then sprays out from the nozzles;

[0052] Among them, the dust reduction assembly is mainly used to reduce the concentration of dust at the rear chute by spraying water. The water spraying process of the dust reduction assembly is controlled by a control module. The control module controls the process of the dust reduction assembly through two control methods. The first control mode sets parameters for the dust reduction assembly according to manual experience, that is, the setting of the first parameter below; the second control mode is that after the dust reduction assembly runs for T time under the first control, if the dust reduction effect meets the requirements, the first parameter is optimized, otherwise the first parameter is adjusted.

[0053] The control module includes: the first control mode and the second control mode;

[0054] The first control mode controls the dust reduction process of the dust reduction assembly 4 based on the production volume of gangue. Under the first control mode, the operating parameters of the dust reduction assembly 4 operate according to the first parameter. The first parameter sets the water flow speed and water flow according to manual experience, and the first parameter is stored in the storage unit below;

[0055] After the second control mode runs for T time based on the first control mode, it adjusts the first parameter of the dust reduction assembly at the rear chute according to the dust concentration in the environment where the current rear chute 1 is located. If the dust concentration in the environment where the current rear chute 1 is located is within the preset parameters, the first parameter is optimized. If the dust concentration in the environment where the current rear chute 1 is located exceeds the preset parameters, the first parameter is regulated until the dust concentration detected after the dust reduction assembly 4 runs for T time with the adjusted first parameter is within the preset parameters;

[0056] The control module further includes: a management and control module for controlling the energy consumption of coal mining equipment; among them, after the management and control module adjusts the energy consumption of coal mining equipment, the first control mode and the second control mode further regulate the first parameter of the corresponding equipment at the rear chute based on the measured dust concentration in the environment where the rear chute is currently located, and finally achieve the control of the environmental dust concentration at the rear chute;

[0057] The control module generates corresponding energy consumption nodes according to the architecture of coal mining equipment, and configures a control node for several mutually related energy consumption nodes according to the association relationship between the several energy consumption nodes; a control system is constructed based on the association relationship between the control node and the energy consumption nodes, and the control system stores the operation condition proportion data of each control node and supports the configuration of energy consumption parameters for associated energy consumption nodes.

[0058] The control system is used to control the operation conditions of various coal mining equipment, and the control module adjusts the operation condition of the rear chute based on the operation conditions of various equipment.

[0059] The control module includes: an energy consumption configuration module and a scheduling module.

[0060] The energy consumption configuration module configures corresponding unit amounts of energy consumption according to the total energy consumption of each energy consumption node in the control system during a preset time period, and distributes the energy consumption according to the energy consumption proportion relationship of each control node in the control system and the energy consumption configuration relationship of the corresponding energy consumption node.

[0061] The energy consumption configuration module is connected to the identifiers assigned to each energy consumption node and the identifiers of each control node, configures corresponding unit amounts of energy consumption according to the total energy consumption of each energy consumption node during a preset time period based on the identifiers, and distributes the energy consumption according to the energy consumption proportion relationship of each control node and the energy consumption configuration relationship of the corresponding energy consumption node based on the identifiers.

[0062] The scheduling module adjusts the energy consumption proportion relationship of each control node and the energy consumption configuration relationship of the corresponding energy consumption node in real time as the energy consumption of the energy consumption nodes changes dynamically. The control node controls the energy consumption distributed by the energy consumption configuration module according to the energy consumption configuration relationship of each energy consumption node.

[0063] The first control mode and the second control mode adjust the operation condition of the rear chute based on the control module. The control module adjusts the operation conditions of the entire coal mining equipment, controls the energy consumption of the coal mining equipment in the coal mine based on the operation conditions of various equipment, adjusts the operation of the equipment based on the control of the energy consumption, and thus adjusts the dust concentration.

[0064] Among them, the energy consumption node is generated based on the architecture of coal mining equipment and represents a single or a group of coal mining equipment units with energy consumption characteristics. Each energy consumption node corresponds to actual coal mining equipment, such as coal shearers, conveyors, ventilators, etc. These equipment consume energy such as electric energy during operation. Each energy consumption node is equipped with a unique identifier to facilitate system identification and management. The system can calculate the total energy consumption of each energy consumption node within a preset time period, which serves as the basic data for energy consumption allocation and management.

[0065] The control node is a logical node that uniformly manages and controls several interrelated energy consumption nodes. These associations can be based on the functional relevance, physical connectivity, or operation timing between devices. For example, a coal shearer and its supporting conveyor are closely related in function and jointly complete the tasks of coal mining and transportation. The energy consumption nodes corresponding to them can be associated and configured with a control node for unified management. The control node also has its own identifier for system identification and operation.

[0066] The determination method of the control node is that the control node is determined according to the association relationship between several energy consumption nodes. In the coal mining scenario, the analysis of the association relationship between energy consumption nodes can start from the following aspects: Functional association: For example, a coal shearer and a scraper conveyor. The coal shearer is responsible for cutting coal, and the scraper conveyor is responsible for transporting the coal. They cooperate with each other functionally, and the corresponding energy consumption nodes can be associated under a control node. Physical association: Devices connected to the same power supply line may affect each other during operation, and the energy consumption nodes corresponding to these devices can be configured with a control node. Timing association: During the mining process, some devices need to operate in a specific time sequence. For example, the ventilator is started first and then the coal shearer. The energy consumption nodes corresponding to these devices with timing association can also be associated to a control node.

[0067] The operation condition occupancy ratio relationship refers to the time ratio or work intensity ratio occupied by each control node under different operation conditions. In coal mining, the operation conditions can include normal mining, equipment maintenance, standby, etc. For example, within a month, the equipment under a certain control node has a normal mining condition occupancy ratio of 70%, an equipment maintenance condition occupancy ratio of 10%, and a standby condition occupancy ratio of 20%. By analyzing the operation condition occupancy ratio relationship, the working mode and equipment utilization rate of the control node can be understood, and it can also provide a basis for energy consumption allocation and equipment management.

[0068] The energy consumption configuration module is a part of the control module and is mainly responsible for the distribution and configuration of energy consumption. It configures the corresponding unit amount of energy consumption for each energy consumption node in the control system according to the total energy consumption of each energy consumption node in the preset time period. At the same time, it distributes the energy consumption according to the energy consumption ratio relationship of each control node in the control system and the energy consumption configuration relationship of the corresponding energy consumption node. For example, it will reasonably distribute the total energy consumption to each control node according to the energy consumption ratio of each control node, and then the control node will distribute the energy consumption to the specific energy consumption node according to the energy consumption configuration relationship of the energy consumption node.

[0069] The scheduling module is also a component of the control module. Its main function is to adjust the energy consumption ratio relationship of each control node and the energy consumption configuration relationship of the corresponding energy consumption node in real time as the energy consumption of the energy consumption node changes dynamically. When the energy consumption of a certain energy consumption node suddenly increases or decreases, the scheduling module will analyze the impact of this change on the entire system, and then adjust the energy consumption ratio of the control node and the energy consumption configuration of the energy consumption node accordingly to ensure the energy utilization efficiency of the system and the normal operation of the equipment.

[0070] Cooperation between the energy consumption configuration module and the scheduling module: The energy consumption configuration module completes the initial energy consumption distribution and distribution work based on preset rules and data, providing a basic energy consumption framework for the operation of the system. The scheduling module monitors the dynamic changes in the energy consumption of the energy consumption node in real time. When it finds that the energy consumption situation does not match the initial configuration, it will adjust the energy consumption ratio relationship of the control node and the energy consumption configuration relationship of the energy consumption node. The energy consumption configuration module redistributes and configures the energy consumption according to the adjusted relationship of the scheduling module. In this way, the two cooperate with each other to form a dynamic closed-loop control system, enabling the energy consumption of coal mining equipment to be optimized and managed in real time according to the actual operating conditions.

[0071] After the energy consumption of the coal mining equipment is adjusted based on the first control mode by the control module, on this basis, the first parameters are set for the dust reduction components at the rear chute and the equipment affecting the dust concentration in the environment at the rear chute, and then the second control mode is carried out after running for T cycles.

[0072] Among them, the control system is a system for managing and coordinating the operating conditions of various coal mining equipment. It is closely related to the control module, and the control module generates energy consumption nodes according to the architecture of the coal mining equipment. These energy consumption nodes represent different energy consumption parts in the equipment.

[0073] For example, in the coal mining scenario, equipment such as roadheader loaders and conveyors have their own energy consumption parts, and these parts can be regarded as energy consumption nodes. The control module will configure a control node for several interrelated energy consumption nodes according to the association relationship between these energy consumption nodes.

[0074] Constituent elements of the control system:

[0075] Storage of operating condition proportion data: The control system stores the operating condition proportion data of each control node. The operating condition proportion data can be understood as relevant data such as the time proportion or energy consumption proportion of each control node in different working states (such as full-speed operation, half-speed operation, etc.) of the equipment. This helps to understand the energy consumption distribution of the equipment in different working states.

[0076] Energy consumption parameter configuration function: The control system is also used to configure energy consumption parameters for associated energy consumption nodes. This means that it can adjust the working parameters of each energy consumption node, such as the power and operating speed of the equipment, so as to control the energy consumption of the equipment. For example, for a conveyor, its operating speed can be adjusted through the control system, thereby changing its energy consumption situation.

[0077] The role of the control system is to control the operating conditions of various equipment in coal mining. And it is mentioned in the text that the control module will adjust the operating conditions of the rear chute based on the operating conditions of each equipment. This shows that the control system is a key part that coordinates the operation of global equipment. It can comprehensively adjust the operating parameters of each equipment according to various factors such as the energy consumption situation of the equipment and the dust concentration at the rear chute, so as to achieve the purpose of both controlling the dust concentration and reasonably controlling the energy consumption.

[0078] The control module includes: a data acquisition unit, a data analysis unit, and a storage unit that are respectively connected to an external controller;

[0079] The data acquisition unit is used to collect the water flow velocity, water flow rate, pressure value of the pressure increasing valve, and the dust concentration in the environment where the current rear chute 1 is located, and send the collected data to the analysis unit and the storage unit;

[0080] The data analysis unit is communicatively connected to the data storage unit. The preset parameters are set in the data analysis unit. The preset parameters are used to compare with the data sent by the data analysis unit, and send the comparison result to the external controller. Based on the comparison result, different signals are sent, and the external controller determines whether to start the second control mode based on the received signal.

[0081] A comparison area is set in the analysis unit, and the preset parameters are stored in the comparison area. The preset parameters are the range of dust concentration required for the coal mining operation environment.

[0082] An early warning module is set in the analysis unit. The early warning module is connected to the external controller. The early warning module is used to receive the signal sent by the external controller and give an alarm;

[0083] Wherein, if the dust concentration in the environment where the current rear chute 1 is located exceeds the preset parameter, the analysis unit sends a first signal to the external connection controller. When the external connection controller receives the first signal, it sends an alarm signal to the warning module, and at this time, the warning module gives an alarm prompt.

[0084] A plurality of storage areas are provided in the storage unit. Each storage area stores the respective data of the dust reduction component 4 corresponding to the dust concentration detected within the preset parameter range after running for T time in the first control mode. After the analysis unit performs data comparison, if the comparison result is within the preset parameter range, the analysis unit sends a second signal to the external connection controller. After receiving the second signal, the external connection controller calls the data in the corresponding storage area and optimizes the first parameter by selecting any one of the data in the corresponding storage area as a reference.

[0085] If the comparison result exceeds the preset parameter range, the analysis unit sends a first signal to the external connection controller. After receiving the first signal, the external connection controller calls the data in the corresponding storage area and adjusts the first parameter by selecting the average value of the data in the corresponding storage area as a reference.

[0086] In some embodiments, when the comparison result is within the preset parameter range and meets the standard for ensuring dust reduction, the external connection controller can lower the operating parameters of each device of the dust reduction component 4, and the lowering range is based on the parameter range formed by the maximum or minimum value and the average value in each storage area.

[0087] Among them, the water flow velocity and water flow rate are set in advance through manual experience, that is, it operates according to the first control mode. After running for T time (T time can be set as needed) in the first control mode, the dust concentration of the current environment is obtained through the data acquisition unit. If the obtained dust concentration is within the preset parameter range (the preset parameter can be set with reference to the dust concentration in the corresponding coal mine mining environment or can be set according to manual requirements), then it can continue in the first control mode, or the external connection control calls the data in the storage area to optimize the first parameter, or the first parameter can be appropriately reduced, and the reduction range can be referred to the range formed by the maximum value and the average value. If the obtained dust concentration exceeds the preset parameter range, the second control mode is started to adjust the first parameter so that the dust concentration obtained by the data acquisition unit is restored to within the transport parameter range.

[0088] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
