Description

Technical Field

[0001] This invention relates to the field of crusher technology, and in particular to an intelligent control system and method for a dust crusher based on wireless communication technology. Background Technology

[0002] Crushing is the process of breaking large pieces of material into smaller pieces, and the equipment used for this operation is called a crusher. There are various types of crushers, such as cone crushers, roller crushers, and jaw crushers. Among them, the single-roll crusher, also known as a jaw roller crusher, is a type of roller crusher and is suitable for crushing medium-hard or soft materials, such as limestone, hard clay, and coal. When the material is relatively sticky and wet, its crushing effect is better than that of jaw and cone crushers, especially for crushing flaky clay materials. Compared with jaw or cone crushers, it has advantages in performance and compactness.

[0003] The outer surface of the roller and the inner curved surface of the jaw plate suspended on the spindle form the crushing chamber, with a support seat at the bottom of the jaw plate. The crushing chamber consists of a rotating roller and a jaw plate. A toothed roller bushing is mounted on the roller core with studs; the tooth tips extend forward like an eagle's beak. The bushing can be replaced when worn. The jaw plate is suspended on the spindle, and its inner surface is lined with wear-resistant plates. The jaw plate is pulled towards the roller by two tie rods and the pressure of springs pressing against the frame, maintaining a certain distance between the jaw plate and the roller. The roller shaft is supported by bearings mounted on the side walls of the frame. When the single-roll crusher is working, the material fed between the two rollers is subjected to friction between the rollers and the material, and as the roller rotates, it is gripped and drawn into the crushing chamber between the two rollers. After being crushed, it is discharged from the bottom.

[0004] Because material is crushed between the two rollers, excessive accumulation or high hardness can prevent crushing, affecting the crusher's operation and even causing it to jam. Therefore, this issue urgently needs to be addressed.

[0005] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an intelligent control system and method for a dust crusher based on wireless communication technology. The system can not only control the crusher to automatically remove the material blocking the two rollers, but also has a simple and efficient control principle, stable operation, and can extend the service life of the crusher.

[0007] To achieve the aforementioned objective, the technical solution of the present invention is as follows: an intelligent control system and method for a dust crusher based on wireless communication technology, comprising: a monitoring module, wherein the monitoring module is used to detect the motor current value of the dust crusher in real time;

[0008] A wireless communication module, which is electrically connected to the monitoring module, is used to convert the motor current value detected by the monitoring module into a wireless signal and transmit it out.

[0009] The blowing device is used to blow away large pieces of material between the two rollers of the dust crusher.

[0010] The intelligent control module is electrically connected to both the wireless communication module and the purging device. It receives the motor current value detected by the monitoring module and controls the purging device to purge the dust crusher with excessive material accumulation.

[0011] Preferably, it also includes a visual recognition unit; the visual recognition unit is electrically connected to both the intelligent control module and the wireless communication module, and is installed on the dust crusher, used to photograph whether the material between the two rollers of the dust crusher has been cleaned, and transmit the photographed image to the intelligent control module through the wireless communication module.

[0012] Preferably, the monitoring module is electrically connected to the motor of the dust crusher and monitors the current information of the motor in real time.

[0013] Preferably, the intelligent control module includes: a data receiving and processing unit, which is electrically connected to the monitoring module and is used to receive the current data of Ma Bao in real time and compare the received current data with pre-stored standard data;

[0014] The motor control unit is connected to the data receiving and processing unit, and controls the motor operation of the dust crusher motor according to the data processing results of the data receiving and processing unit.

[0015] Preferably, the purging device includes a valve group control unit, which is used to adjust the airflow at the outlet of the purging device.

[0016] Preferably, the purging device includes a material removal unit, which is equipped with a robotic arm for auxiliary material removal. The robotic arm is used to remove large pieces of material that cannot be blown out by the purging air.

[0017] Preferably, the wireless communication module adopts DP communication technology.

[0018] Preferably, the monitoring module is a current and voltage measuring instrument.

[0019] Preferably, the purging device uses nitrogen purging.

[0020] Preferably, the control method of the control system is as follows:

[0021] S1, the monitoring module reads the current data of the motor of the dust crusher and transmits the current data to the data receiving and processing unit of the intelligent control module;

[0022] S2, the data receiving and processing unit compares the received current data with the pre-stored standard data; if the current data exceeds the preset value, the control unit sends a control command to the motor of the dust crusher through the motor control unit.

[0023] The dust crusher is controlled to close the feeding valve, and then the running motor of the dust crusher is stopped. The running motor of the dust crusher is started to reverse, and the blowing device is turned on to blow large pieces of material and materials with high hardness out between the two rollers of the dust crusher.

[0024] S3, the motor of the dust crusher stops reversing every ten minutes and starts rotating forward. If the current of the motor is still above the set value, repeat the control process of S2, and the blowing device increases the air force at the outlet of the blowing device through the valve group control unit. Repeat the control process of S2 at least three times. If the monitoring module reads that the current of the motor returns to normal during the repetition of step S2, the intelligent control module shuts down the blowing device and controls the Ma Bao control unit to control the dust crusher to open the feeding valve and restart the crushing operation.

[0025] S4. If the control process of S2 is repeated three times and the monitoring module reads that the current of the motor running the dust crusher still exceeds the set value, the intelligent control module controls the visual recognition unit to take a picture of whether the material between the two rollers of the dust crusher has been blown clean, and transmits the captured image to the intelligent control module through the wireless communication module; the intelligent control module transmits the image to the background computer or display screen and issues an alarm that requires human assistance.

[0026] S5, the back-end operator observes the video. If the material between the two rollers of the dust crusher is large and stuck between the two rollers and cannot be blown out, the back-end operator starts the material removal unit and remotely operates the robotic arm to remove the material stuck between the two rollers of the dust crusher.

[0027] S6. If the operator observes the video and there is no material between the two rollers of the dust crusher, indicating that the material has been blown away, then the operator determines that the motor of the dust crusher is faulty and immediately stops the machine for inspection and repair.

[0028] The beneficial effects of this invention are reflected in:

[0029] (1) The control system of this invention promptly detects large pieces of material blocking the inside of the dust crusher through the monitoring module, and controls the operating motor of the dust crusher to reverse through the intelligent control module. At the same time, the purging device is activated, and nitrogen is automatically opened for purging using the valve group control unit to remove the large pieces of material. This is not only simple and efficient, but also reduces the number of times the dust crusher needs to be disassembled, reduces the maintenance time of the dust crusher, and improves the troubleshooting efficiency of the dust crusher.

[0030] (2) By setting up a material removal unit, the present invention enables back-end operators to remotely remove large pieces of material that cannot be blown out by the blowing air, thereby improving the flexibility of the control system.

[0031] (3) By setting up a visual recognition unit, the present invention enables operators to observe the internal condition of the dust crusher in a timely manner from the background, facilitating the verification of the system's troubleshooting results. It also allows operators to remotely assist in cleaning materials and troubleshooting. Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] This invention provides an intelligent control system and method for a dust crusher based on wireless communication technology, comprising:

[0035] The monitoring module is electrically connected to the motor of the dust crusher and monitors the motor's current information in real time, thereby enabling real-time detection of the motor current value of the dust crusher. In practical applications, the monitoring module is configured as a current and voltage measuring instrument.

[0036] Since the two rollers of the dust crusher are driven by a motor, when material blockage occurs between the rollers, the resistance of the motor increases, causing a change and subsequent increase in the internal current. By monitoring the current value of the dust crusher's motor, back-end personnel can determine the motor's operating status based on the fluctuations in the current value, thereby understanding the internal workings of the dust crusher—a simple and efficient method.

[0037] The wireless communication module is electrically connected to the monitoring module and uses DP communication technology to convert the motor current value detected by the monitoring module into a wireless signal for transmission.

[0038] This setup allows the values ​​detected by the monitoring module to be transmitted in real time, replacing the process of manual observation and information transmission, freeing up manpower, and making the process more efficient and timely.

[0039] The purging device is used to purge large pieces of material between the two rollers of the dust crusher.

[0040] The purging device mainly consists of a valve group control unit and a material removal unit.

[0041] The valve group control unit is used to adjust the airflow at the outlet of the purging device, which uses nitrogen for purging.

[0042] When there is a lot of material between the two rollers of the dust crusher, increasing the air force at the outlet of the blowing device can speed up the material cleaning process and improve the system's maintenance efficiency for the dust crusher.

[0043] The material removal unit is equipped with an auxiliary robotic arm for retrieving large pieces of material that cannot be blown out by the blowing air. This setup allows operators to control the robotic arm remotely to remove such materials, avoiding the tedious work of disassembling the dust crusher on-site and improving the efficiency of troubleshooting.

[0044] The intelligent control module is electrically connected to both the wireless communication module and the purging device. It receives the motor current value detected by the monitoring module and controls the purging device to purge the dust from the crusher when there is too much accumulated material.

[0045] The intelligent control module includes a data receiving and processing unit and a horse-breathing control unit.

[0046] The data receiving and processing unit is electrically connected to the monitoring module to receive the current data of the motor in real time and compare the received current data with the pre-stored standard data.

[0047] The motor control unit is connected to the data receiving and processing unit, and controls the motor operation of the dust crusher motor based on the data processing results of the data receiving and processing unit.

[0048] This setup allows for real-time monitoring of the dust crusher's operation and timely material removal for any abnormalities. This not only frees up manpower but also enables prompt handling of crusher malfunctions, preventing damage, reducing maintenance costs, and achieving maintenance without downtime, thereby improving production efficiency.

[0049] It also includes a visual recognition unit; the visual recognition unit is electrically connected to both the intelligent control module and the wireless communication module, and is installed on the dust crusher. It is used to photograph whether the material between the two rollers of the dust crusher has been cleaned, and transmits the captured images to the intelligent control module via the wireless communication module. Generally, the visual recognition unit uses a small, high-definition camera with wireless transmission capabilities.

[0050] This setup allows operators to monitor the material clearance between the two rollers without disassembling the dust crusher, enabling them to verify the system's cleaning performance and ensuring real-time validation of its effectiveness, thus improving system stability. Furthermore, it facilitates operator observation of the crusher's interior, allowing for timely detection of situations where there is no material between the rollers but the motor continues to operate abnormally, improving troubleshooting efficiency and reducing costs.

[0051] Example 2

[0052] The control method of the control system is as follows:

[0053] S1, the monitoring module reads the current data of the motor of the dust crusher and transmits the current data to the data receiving and processing unit of the intelligent control module.

[0054] S2, the data receiving and processing unit compares the received current data with the pre-stored standard data; if the current data exceeds the preset value, the control unit sends a control command to the motor of the dust crusher through the motor control unit.

[0055] The dust crusher is controlled to close the feeding valve, which immediately stops the operation of the dust crusher's motor. The motor is then started in reverse, and the blowing device is activated to blow large pieces of material and materials with high hardness out between the two rollers of the dust crusher.

[0056] S3: The motor of the dust crusher stops reversing every ten minutes and starts rotating forward. If the current of the motor is still above the set value, repeat the control process of S2. The blowing device increases the air force at the outlet of the blowing device through the valve group control unit. Repeat the control process of S2 at least three times. If the monitoring module reads that the current of the motor returns to normal during the repetition of step S2, the intelligent control module shuts down the blowing device and controls the Ma Bao control unit to control the dust crusher to open the feeding valve and restart the crushing operation.

[0057] S4. If the control process of S2 is repeated three times and the monitoring module reads that the current of the motor running the dust crusher still exceeds the set value, the intelligent control module controls the visual recognition unit to take a picture of whether the material between the two rollers of the dust crusher has been blown clean, and transmits the captured image to the intelligent control module through the wireless communication module; the intelligent control module transmits the image to the background computer or display screen and issues an alarm that requires human assistance.

[0058] S5, the back-end operator observes the video. If the material between the two rollers of the dust crusher is large and stuck between the two rollers and cannot be blown out, the back-end operator starts the material removal unit and remotely operates the robotic arm to remove the material stuck between the two rollers of the dust crusher.

[0059] S6. If the operator observes the video and there is no material between the two rollers of the dust crusher, indicating that the material has been blown away, then the operator determines that the motor of the dust crusher is faulty and immediately stops the machine for inspection and repair.
