Description

Technical Field

[0001] The present invention relates to the technical field of slag treatment, and particularly to an automatic alarm device and system for a crusher used in slag treatment. Background Technique

[0002] Slag separation is an important link in the metallurgical industry. Its main purpose is to effectively separate and recycle the slag generated during the smelting process to improve resource utilization rate and reduce environmental pollution. The preliminary treatment equipment for slag separation is a crusher. The main function of the crusher is to preliminarily crush large pieces of slag into smaller particles. This process can not only improve the efficiency of subsequent separation but also provide more uniform materials for subsequent treatment.

[0003] When the crusher is running, problems such as abnormal vibration of the machine body, abnormal heating of bearings, and too large particle size of the discharged materials may occur. These problems may be caused by various reasons such as excessive metal foreign objects in the materials, wear of the hammers, and imbalance of the rotor. However, the existing monitoring of crusher operation is not comprehensive enough. Maintenance personnel monitor the operation of the crusher through the monitoring screen and electrical box information, which is relatively one-sided and cannot fully cover the causes of various possible failures. An alarm may not be triggered when the operation is abnormal. For this reason, we propose an automatic alarm device and system for a crusher used in slag treatment. Summary of the Invention

[0025] Support 6: It is arranged in the middle of the crusher 1. An infrared thermal imager 7 is fixedly connected to the upper end of the support 6. Both the crusher 1 and the motor 2 are located below the infrared thermal imager 7. During this period, the infrared thermal imager 7 feeds back the infrared thermal image of the crusher 1 to the controller 10. The controller 10 focuses on monitoring the temperature at the positions of the motor bearings, motor windings, inside the crushing chamber, and main shaft bearings, and controls the motor 2 according to the temperature monitoring mechanism. When the temperature at a certain position exceeds the safety threshold, the motor 2 and the belt conveyor 51 stop running, and the sound and light alarm 12 gives an alarm.

[0026] Among them: It also includes a controller 10. The controller 10 is arranged on the left side of the crusher 1. A communicator 11 is arranged at the front end of the controller 10.

The key positions of the temperature information received by the controller 10 are: motor bearings, motor windings, inside the crushing chamber, and the main shaft bearings are divided into a predetermined value and a safety threshold. When the temperature information continuously exceeds 30% of the predetermined value for three minutes, the controller 10 controls the motor 2 to decelerate. The key positions of the temperature information received by the controller 10 are: motor bearings, motor windings, inside the crushing chamber, and the main shaft bearings continuously exceed the safety threshold for three minutes, the controller 10 triggers shutdown protection. It includes a foreign object discharge mechanism. After the metal detector 52 detects a metal foreign object, the controller 10 controls the belt conveyor 51 to discharge it in reverse. After waiting to clean the metal foreign object, it resumes the original working state. The controller 10 uploads the alarm information to the cloud platform through the communicator 11. The cloud platform conducts historical comparison and recording, and at the same time sends an information reminder to the maintenance personnel.

[0029] An automatic alarm device and system for a slag treatment crusher, including an automatic alarm device for a slag treatment crusher.

[0030] The working principle of the automatic alarm device and system for a slag treatment crusher provided by the present invention is as follows: The slag is sent into the interior of the crushing chamber of the crusher 1 through the belt conveyor 51. The metal detector 52 monitors the slag. The metal detector 52 is located inside the avoidance opening, so that only the conveyor belt of the belt conveyor 51 passes through the interior of the metal detector 52. The metal detector 52 sets a trigger value. When a metal foreign object larger than the set value passes through the metal detector 52, it is triggered, and the foreign object discharge mechanism is activated. The controller 10 controls the belt conveyor 51 to discharge in the reverse direction. After the worker clears the metal foreign object, it resumes the original working state. The crusher 1 crushes the slag. During this period, the infrared thermal imager 7 feeds back the infrared thermal image of the crusher 1 to the controller 10. The temperature information received by the controller 10 (the key positions are: motor bearings, motor windings, inside the crushing chamber, and main shaft bearings) is divided into a preset value and a safety threshold. When the temperature information continuously exceeds 30% of the preset value for three minutes, the controller 10 controls the motor 2 to reduce its speed. When the key positions of the temperature information received by the controller 10, namely the motor bearings, motor windings, inside the crushing chamber, and main shaft bearings, continuously exceed the safety threshold for three minutes, the motor 2 and the belt conveyor 51 stop running, and the audible and visual alarm 12 emits an alarm. At the same time, the controller 10 uploads the alarm information to the cloud platform through the communicator 11. The cloud platform conducts historical comparison and recording, and at the same time sends an information reminder to the maintenance personnel. The acoustic emission sensor 13 collects the acoustic signature characteristics during the slag crushing process and compares them with the acoustic signature database. The acoustic signature database records the acoustic signature characteristics of the normal operation of the crushing roller, the acoustic signature characteristics of the fracture of the parts constituting the crushing roller, the acoustic signature characteristics of the cavity collision, and the acoustic signature characteristics of the bearing failure. After the controller 10 discovers abnormal acoustic signature characteristics, it also issues an alarm in the same way. A monitor of the Rogowski coil 9 is fixedly sleeved outside the cable of the motor 2. The Rogowski coil 9 monitors the current change of the motor 2, and the vibration sensor 8 monitors the vibration of the motor 2 to realize the monitoring of the operating state of the motor 2.
