Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, and in particular to an intelligent dust removal control system and equipment for mining excavators. Background Technology

[0002] Dust pollution is a crucial environmental protection indicator for open-pit mining. Dust generated in mining includes dust from blasting; dust from ore or topsoil extraction and loading; dust generated on the road surface during mine car operation; and dust generated after unloading from mine cars. Because dust is abundant, it not only causes severe environmental pollution and poses significant health risks, but also greatly impacts the lifespan of mining equipment used in production.

[0003] To reduce dust generated during mining operations, most mines currently only use water trucks to spray water on the roads where mining trucks travel. This only suppresses dust generated by the trucks, and there are almost no reliable solutions for other pollution sources. As a result, the environmental pollution during mining operations is severe, which is unfriendly to mining workers and equipment, affects the health of mining workers, reduces the service life and reliability of mining equipment, and poses potential safety hazards.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] This invention not only detects dust generated during excavation operations, from the moment the excavator bucket contacts the soil until it completes loading, but also detects dust generated during the transfer and dumping of coal and other minerals after excavation, i.e., dust generated during the unloading of material from the bucket into mining cars or other vehicles. It enables dust detection throughout the entire excavator operation process, effectively reducing dust generated during mining or bucket unloading, thus minimizing dust generated during excavation and preventing environmental pollution.

[0033] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This document provides a detailed description of the technical solutions provided in the embodiments of this utility model.

[0034] Example 1

[0035] As attached Figure 1 As shown in the figure, this utility model embodiment provides an intelligent dust removal control system for mining excavators. The system includes: multiple detection devices 1, control devices 2, and one or more spray dust removal devices 3, wherein:

[0036] Multiple detection devices 1 are symmetrically arranged on a mining excavator. The detection accuracy of the multiple detection devices 1 is positively correlated with the dust concentration generated during mining, and the detection accuracy of the multiple detection devices 1 completely covers all concentration ranges of dust generated during mining. The control device 2 is used to divide the dust concentration generated during mining into multiple continuous concentration ranges according to the number of multiple detection devices 1, so that each concentration range corresponds to at least one detection device 1 with the same detection accuracy. At the same time, the measurement accuracy of the multiple detection devices 1 is matched one-to-one according to the size of the multiple concentration ranges. One or more spray dust removal devices 3 are connected to the control device 2 so that the control device 2 can control the opening degree of the spray dust removal switch 52 of one of the spray dust removal devices 3 or control one or more of the multiple spray dust removal devices 3 to perform simultaneous spray dust removal operations according to the dust concentration detected by the multiple detection devices 1.

[0037] This invention discloses an intelligent dust removal control system for mining excavators. By setting multiple detection devices 1, and distributing the detection accuracy of these devices 1 to a level positively correlated with the dust concentration generated during mining, and ensuring that the detection accuracy of these devices completely covers all concentration ranges of dust generated during mining, this intelligent dust removal control system can fully and completely detect the dust concentration in the excavator's working environment. By setting one or more spray dust removal devices 3, and controlling the opening degree of the spray dust removal switch 52 of one of the spray dust removal devices 3 or controlling one or more of the multiple spray dust removal devices 3 to perform simultaneous spray dust removal operations, the system can freely control the amount and size of the spray water during the dust removal process. This allows for rapid and effective dust removal while minimizing the waste of spray water resources, preventing damage to equipment due to excessive humidity or creating a muddy and slippery working environment during dust removal, and ensuring the safety of the equipment and personnel in the working space. Therefore, it can improve the service life and reliability of mining equipment and eliminate potential safety hazards.

[0038] In this embodiment of the invention, the detection accuracy of multiple detection devices 1 is set to be positively correlated with the dust concentration generated by mining, and the detection accuracy of multiple detection devices 1 completely covers all concentration ranges of dust generated by mining. That is, multiple detection devices 1 are set in this embodiment of the invention, and the detection accuracy of multiple detection devices 1 is set to be different. The detection accuracy range of multiple different detection devices 1 is matched with or covers the concentration range of dust generated by mining. The measurement accuracy of multiple detection devices 1 is matched one-to-one according to the size of the divided concentration ranges. So that in the dust removal process, it is only necessary to control the spraying method or spraying size that matches the dust concentration according to the detection accuracy of different detection devices 1, that is, when different detection devices 1 detect the corresponding dust content, to realize the dust removal operation of different spraying devices.

[0039] For example, when a first-precision detection device 1 detects a first dust concentration, spraying is performed according to a spraying device or spraying method matched with the first-precision detection device 1. When a second-precision detection device 1 detects a second dust concentration, the second precision is greater than the first precision, and the concentration boundary is continuous with the boundary of the first dust concentration. The second dust concentration is greater than the first dust concentration, and spraying is performed according to a spraying device or spraying method matched with the second-precision detection device 1. When a third-precision detection device 1 detects a third dust concentration, the third precision concentration is greater than the second dust concentration, and the concentration boundary is continuous with the boundary of the first dust concentration. When the concentration of the second dust is continuous with the boundary, spraying is carried out according to the spraying equipment or spraying method matched with the third precision detection equipment 1. For example, during the control of spraying, a signal detected by a certain precision detection equipment 1 is used to control a certain spraying equipment. When the detection equipment 1 of one type detects the corresponding concentration signal, the control equipment 2 receives the signal and controls the corresponding spraying equipment to carry out the spraying operation. When the detection equipment 1 of another type detects the corresponding concentration signal, the control equipment 2 receives the detection signal of the other detection equipment 1 and controls the spraying equipment corresponding to the other detection equipment 1 to carry out the spraying operation.

[0040] This setup ensures that, due to the continuous detection accuracy of the detection device 1, the device can fully and adequately detect different dust concentrations generated during the mining process and promptly remove dust according to the dust concentration, thus guaranteeing the dust removal effect and efficiency. Furthermore, it saves resources and ensures the safety of operating equipment and personnel during the dust removal process.

[0041] In this embodiment of the invention, dust removal is achieved by controlling different quantities or sizes of spray water flow simply by receiving different concentration signals. The structure is simple, the control method is simple and efficient, the cost is low, it is environmentally friendly, and it ensures the safety of the operating equipment and personnel.

[0042] In some optional implementations of this embodiment, the detection device 1 includes a dust concentration sensor, the control device 2 includes a PLC controller or an industrial computer, and the spray dust removal device 3 includes a water tank, a pipe connected to the water tank, a spray dust removal switch 52 connected to the pipe, a control unit connected to the spray dust removal switch 52, and a spray head connected to the spray pipe to form a spray device or spray system.

[0043] In some optional implementations of this embodiment, the power source for the sensor installed on the excavator can be the excavator itself, or an independent power module installed on the excavator, or an independent power module installed on the excavator that is charged by the excavator. In addition, for ease of disassembly and installation, and for ease of maintenance, the power module can also be set as a detachable quick-release power supply, which is powered by an external power source after being disassembled.

[0044] This configuration ensures that the sensors and other detection devices 1 have sufficient power, maintain continuous detection, and thus ensure dust removal quality and effectiveness.

[0045] By installing multiple detection devices 1 on the excavator, dust can be detected under any working condition of the excavator. For example, during the excavation process, the detection devices 1 on the excavator can detect the dust generated during excavation; during the unloading process, the dust generated during unloading can be detected; and during the transfer process, the dust generated during transfer can be detected. Therefore, the dust removal system of this embodiment can realize dust detection throughout the entire process of excavator excavation, and can ensure environmental safety throughout the entire process.

[0046] To enable more accurate detection of dust content, the detection device 1 is placed near the dust-generating parts of the excavator. For example, dust is easily generated in the bucket during excavation, so the detection device 1 is placed near the boom and arm near the bucket. During unloading, it is necessary to ensure that the detection device 1 does not affect normal production operations and is not damaged during normal operation. The specific placement location is determined according to the excavator's operating conditions and different models.

[0047] Considering extreme weather conditions in the working environment, such as wind, and the influence of wind direction and other factors, the detection equipment 1 is symmetrically set on the left and right sides of the excavator, including the left and right sides of the boom and forearm, in order to eliminate the problem of uneven and inaccurate detection, which would cause inaccurate dust spraying.

[0048] In some optional implementations of this embodiment, the number of spray dust removal devices 3 is set to one, the number of dust sensors is set to two, and the detection accuracy of the two sensors is set to two consecutive intervals, such as a low concentration interval and a high concentration interval. When the sensor detects a low concentration interval, the controller controls the switch of the spray device to open, and controls the spray volume to half of the full spray volume, that is, controls the opening degree of the spray switch of the spray device to half. When the sensor detects that the dust is of a high concentration, the spray switch of the spray device is controlled to be fully open.

[0049] This allows for precise matching of the spray volume to the dust concentration during dust removal operations, preventing slippery and muddy working environments caused by excessive spray volume, which could hinder the passage of equipment and personnel and pose potential risks. It also reduces waste of spray water within the equipment, conserving resources. Furthermore, it avoids the risk of rust and damage to excavators and other equipment caused by prolonged exposure to spray water due to excessive spray volume, further ensuring the safety of excavators and other operating equipment.

[0050] In some optional implementations of this embodiment, the number of spray dust removal devices 3 is set to two, and the number of dust sensors is set to two, so that the two sensors correspond to the two spray dust removal devices 3. For example, the detection accuracy of the two detection devices 1 is set to be continuous but different, such as a low-concentration sensor and a high-concentration sensor. When the low-concentration sensor detects dust, one spray device is controlled to perform a small amount of light spraying, so that the amount of water sprayed by the spray dust removal device 3 is adapted to the dust concentration detected by the low-concentration sensor. When the high-concentration sensor detects that the dust concentration is high, the high-concentration sensor transmits the detected control signal to the controller. The controller controls the other spray dust removal device 3 to the maximum spray volume, so that its spray volume is adapted to the detected high-concentration dust, thereby enabling rapid dust removal.

[0051] During the dust removal process, the two sensors mentioned above continue to operate. When the detected dust concentration is lower than the high concentration, the spray dust removal device 3 corresponding to the high concentration stops working. When the dust concentration in the environment is lower than the concentration detected by the low concentration sensor, the spray device controlled by the low concentration sensor stops working. Thus, through the continuous detection of the sensors and other detection devices 1, feedback adjustment of dust removal can be achieved, which can ensure dust removal efficiency while reducing the waste of spray water resources.

[0052] In some optional implementations of this embodiment, the number of spray dust removal devices 3 is set to three, and the number of dust sensors is set to three, so that each of the three sensors corresponds to one spray dust removal device 3. At the same time, the accuracy of the three sensors is set to continuous and different accuracy levels, so that feedback adjustment can be performed during the dust removal process to ensure dust removal efficiency.

[0053] In another optional implementation of this embodiment, in order to reduce dust removal costs and the space occupied by dust removal equipment, the number of dust removal equipment can be set to two, and the number of sensors can be set to three or three groups. The detection accuracy of the three or three groups of sensors is continuous. For example, the three or three groups of sensors can be set as low concentration, medium concentration and high concentration sensors, corresponding to low accuracy, medium accuracy and high accuracy. The two dust removal equipment correspond to low accuracy and medium accuracy dust removal modes. For example, when the low accuracy sensor detects a low concentration, it transmits the detected control signal to the controller. The controller controls the low accuracy dust removal equipment to perform spraying operation. When the medium accuracy detection device 1 detects a medium concentration of dust, it controls the medium accuracy dust removal equipment to operate. When the high accuracy sensor detects a high concentration of dust, it controls the low concentration and medium concentration dust removal equipment to operate simultaneously. When the dust concentration is close to the medium concentration, the controller receives the control signal of the corresponding sensor and turns off the switch of the corresponding dust removal equipment until the dust concentration is reduced to below the low concentration. Thus, the dust removal operation is achieved through feedback adjustment, ensuring dust removal efficiency and reducing the waste of spray water.

[0054] In some optional implementations of this embodiment, different spray heads can be set on different spraying devices, so that different spray heads spray water with different flow rates and sizes, such as shower heads. In this embodiment of the invention, one or more spray modes such as shower heads can be set on each spraying device. For example, if three spray modes with different flow rates and sizes are set on one spray head, then three detection devices 1 such as sensors are set. The detection accuracy of the three sensors corresponds one-to-one with the three spray modes with different flow rates and sizes on one spraying device. For example, the detection accuracy of the three sensors is set to low accuracy, medium accuracy, and high accuracy, corresponding to the first spray mode, the second spray mode, and the third spray mode of one spraying device, and the spray volume of the third spray mode is... The spray volume of the first spray mode is greater than that of the second spray mode, and the spray volume of the second spray mode is greater than that of the first spray mode. Here, low precision corresponds to low concentration, medium precision corresponds to medium concentration, and high precision corresponds to high concentration. When the low-precision sensor detects low-concentration dust, the first spray mode of one detection device 1 is controlled. When the medium-precision detection device 1 detects medium-concentration dust, the second spray mode of one detection device 1 is controlled. When the high-precision detection device 1 detects high-concentration dust, the third spray mode of one detection device 1 is controlled. Furthermore, during the dust removal process, when the dust concentration decreases from high to medium to low, the corresponding spray mode is also turned off, achieving closed-loop control with feedback adjustment, further improving the dust removal effect and reducing the waste of spray water.

[0055] Furthermore, in this embodiment of the invention, each of the above-mentioned spraying devices can be set to different spraying modes, so that different spraying modes correspond to different flow rates of spray water for dust removal.

[0056] For example, three spraying devices are set up, each with three spraying modes. To further ensure the efficiency and quality of dust removal and reduce the waste of spraying water, nine sensors are set up to detect the dust concentration during the excavator's operation. The detection accuracy of the nine sensors completely covers the entire range of dust concentration generated by the excavator during the dust removal process. At the same time, the detection accuracy of the nine sensors is set to a continuous range to avoid problems such as poor dust removal effect and untimely dust removal due to oversights in sensor detection accuracy. Simultaneously, the spraying modes of the three spraying devices are set to nine continuous spraying modes with different spray volumes. The spraying modes are then sequentially assigned to the detection accuracy of the nine sensors, from low to high. When the sensors detect dust at different concentrations, the detected control signals are transmitted to the controller. The controller then controls the corresponding dust removal device to perform dust removal operations. During the dust removal process, when the dust concentration is reduced, the previous dust removal mode is adjusted based on the sensor detection, reducing the waste of spray water, ensuring dust removal efficiency and keeping the working surface dry, and ensuring the safety of the equipment and personnel.

[0057] In some optional implementations of this invention, multiple dust removal devices of different levels are set up to achieve a more thorough dust removal effect. Multiple mixed dust removal modes are set up to improve dust removal efficiency and speed up the process. Feedback adjustment is used to adjust the dust concentration to conserve dust removal resources and reduce waste. Multiple control methods are employed to prevent damage to equipment due to excessive humidity or muddy and slippery conditions caused by dust removal, ensuring the safety of equipment and personnel in the workspace. Furthermore, multiple detection devices are set up for continuous monitoring of the entire excavator operation process. Therefore, the intelligent dust removal control system for mining excavators provided by this invention has a good dust removal effect, can detect dust concentration and perform corresponding dust removal at all stages of excavator operation, and can reduce the waste of spray water resources. By ensuring a dry working environment, the safety of equipment and personnel is further guaranteed.

[0058] Example 2

[0059] As attached Figure 2 As shown, in addition to the device of one of the above embodiments, this embodiment of the invention also includes a display device 4, which is used to display the spray water pressure of the dust removal equipment and the water volume stored in the water tank.

[0060] For example, display device 4 includes a display screen.

[0061] This setup allows for the monitoring of the spray water volume, preventing interruptions in the spray dust removal operation due to insufficient or interrupted spray water, which could lead to poor dust removal efficiency and environmental pollution, thus ensuring the continuity of dust removal operations.

[0062] Example 3

[0063] As attached Figure 3 As shown, in addition to the device of one of the above embodiments, this embodiment of the invention also includes a control handle 5. The control handle 5 is located in the cab and is connected to the control device 2. The control handle 5 is provided with a master control switch 51 and one or more spray dust removal switches 52, so that the control device 2 can cut off the control of one or more spray dust removal devices 3 through the master control switch 51, and one or more spray dust removal switches 52 can manually control one or more spray dust removal devices 3.

[0064] This configuration enables the dust removal system of the present invention to be controlled manually and automatically, thereby increasing the practicality of the control system of the present invention.

[0065] Example 4

[0066] As attached Figure 4 As shown, in this embodiment of the invention, in addition to the device of one of the above embodiments, an alarm unit 6 is also provided on the display device 4. The alarm unit 6 is connected to one or more spray dust removal devices 3 and the display device 4. The alarm unit 6 is used to trigger an alarm when the water volume in one or more spray dust removal devices 3 reaches the minimum limit.

[0067] In some alternative implementations, the alarm unit 6 includes one or more of the following: a buzzer, an audible and visual alarm, or a highlighting or flashing display on the display device 4.

[0068] This setup allows the alarm unit 6 to replenish the spray water in the spray dust removal equipment 3 in a timely manner, further ensuring the spray dust removal effect and preventing interruption that could pollute the environment.

[0069] In some optional implementations of this embodiment, the opening degree of the spray device switch can be controlled by a hydraulic valve and its corresponding control element, or by a servo motor controlling the spray switch size. For example, the rotating part of the servo motor can be fixedly connected to the spray switch, so that the spray switch rotates synchronously as the servo motor rotates. This allows the control device 2 to control the servo motor to rotate by a certain angle while simultaneously causing the spray switch to rotate by a corresponding angle, thus adjusting the spray volume of the spray device.

[0070] Example 5

[0071] As attached Figure 5 As shown, the embodiments of the present invention are provided with all the features of the above embodiments one to four, and have all the effects of the above embodiments one to four.

[0072] Example 6

[0073] like Figures 6-7 As shown, the system provided in this embodiment of the invention has two modes: manual mode and autonomous mode. The manual mode is controlled by a handle, while the autonomous mode is controlled by a controller and monitoring equipment through feedback adjustment.

[0074] For example, in manual mode, controls such as the main control system switch, manual spray switch, and mode switching switch are provided on the operating handle in the driver's cab. In some alternative implementations, the main control system switch and mode switching control buttons are concentrated on the center console; the manual spray switch is located on the operating handle, such as... Figure 6 As shown, the manual spray switch is positioned at a height h from the commonly used hand position to avoid accidental activation when not needed.

[0075] In some optional implementations of this embodiment, when the dust level is low or dust removal is not required, the autonomous mode switch can be turned off, and the spraying system will stop working. To activate the manual control mode, the manual mode of the central controller must be turned on, and then the spray switches can be manually switched on and off, allowing for on-demand system spraying.

[0076] In some optional implementations of this embodiment, a control panel can also be set, such as... Figure 7 As shown, the control panel is set up with a mode switching function. For example, the integrated knob is used to adjust the manual mode and the automatic mode for easy operation; the water pressure adjustment knob can adjust the water pressure within a certain range according to the usage scenario, thereby controlling the amount of water discharged from the nozzle; the screen display can show the currently used mode; the currently selected water pressure can also be displayed in real time, and the system water volume can be displayed, with water volume warning prompts.

This results in good dust removal performance when the device is used for dust removal, enabling the detection and corresponding dust removal of dust concentration throughout all operating stages of the excavator. It also reduces the waste of spray water resources and further ensures the safety of the equipment and personnel by maintaining a dry working environment.

[0079] In this embodiment of the invention, dust removal modes are specifically set for different operating methods. To achieve more thorough dust removal, multiple dust removal devices of different levels are set up. To improve dust removal efficiency and speed up the process, multiple mixed dust removal modes are set up. To conserve dust removal resources and reduce waste during the dust removal process, a feedback adjustment method is used to adjust the dust concentration accordingly. To prevent equipment damage due to excessive humidity or muddy and slippery working environment caused by dust removal, and to ensure the safety of operating equipment and personnel in the working space, multiple control methods are adopted. At the same time, to enable comprehensive detection and monitoring of the entire excavator operation process, multiple detection devices 1 are set up for continuous detection. Therefore, the intelligent dust removal control system for mining excavators provided by this embodiment of the invention has good dust removal effect, can detect dust concentration and perform corresponding dust removal in all stages of excavator operation, and can also reduce the waste of spray water resources. By ensuring a dry working environment, the safety of operating equipment and personnel is further guaranteed.
