Description

Technical Field

[0001] The utility model relates to the technical field of online operation detection and alarm devices for ring coolers, in particular to an online operation detection and alarm device for ring coolers driven by a latch. Background Art

[0002] The ring cooler plays a vital role in the sintering process and has a direct impact on the efficiency and quality of the entire production process. In order to improve the operating stability of the ring cooler, the drive mode of the 1# ring cooler was changed from the original friction wheel drive to the current pin drive at the beginning of 24. Because the ring cooler is large in size, complex in structure, and has a harsh working environment, strengthening the operation protection device of the ring cooler is a necessary means to ensure the safe production of sintering. However, in terms of the operation detection of the ring cooler, it is only the operation signal of the motor. If a fault occurs outside the motor end, the staff cannot discover and deal with the ring cooler fault in time, which will lead to a series of coherent effects and cause the accident to expand. The occurrence of equipment accidents is not only related to the value of the equipment itself, but also the length of downtime and production suspension has different degrees of impact on the entire sintering process and even the blast furnace smelting process; therefore, installing an effective protection device on the ring cooler is an important measure for the ultimate efficient development of sintering. In order to solve the above problems, a pin-driven online operation detection alarm device for the ring cooler is proposed. Summary of the invention

[0003] The utility model aims to solve the above problems and provides a latch-driven online operation detection and alarm device for annular coolers.

[0004] The specific scheme of the utility model is: a latch-driven online operation detection alarm device for an annular cooler, comprising: an annular cooler rotating body, a transmission gear meshingly connected to the side of the annular cooler rotating body; an induction sensor corresponding to the transmission gear is arranged above the transmission gear, a control module is arranged on one side of the induction sensor, the induction sensor is signal-connected to the control module, an audible and visual alarm is connected to one side of the control module, and the audible and visual alarm is used for voice-controlled alarm.

[0005] Furthermore, transmission gears are provided on both sides of the rotating body of the ring cooler. The left transmission gear is located on the left side, and the left sensing sensor corresponds to the left transmission gear; the right transmission gear is located on the right side, and the right sensing sensor corresponds to the right transmission gear. The left sensing sensor and the right sensing sensor are both connected to the control module signal, and the control module is provided with a left sound and light alarm corresponding to the left sensing sensor, and the control module is provided with a right sound and light alarm corresponding to the right sensing sensor.

[0006] Furthermore, an operating computer is connected to one side of the control module, and the operating computer is used to display the working status of the left transmission gear and the right transmission gear.

[0007] Furthermore, the control module is a PLC controller.

[0008] The working principle of the utility model is as follows: two induction sensors are used to continuously detect the movement state of the transmission gear meshing with the rotating body of the ring cooler. When the gear teeth of the transmission gear rotate to the bottom of the induction sensor, the induction sensor will send a signal to the PLC controller that the equipment is running; when the PLC controller detects that the input signal is lost, it will output an alarm signal to the operating computer and the sound and light alarm; if the input signal is still not detected within the set time, a shutdown signal will be output to the interlocking device, thereby realizing abnormal alarm of the equipment and avoiding the expansion of accidents; the operating computer can choose whether to put the detection device into use, and can set a free alarm time according to the operating status of the ring cooler, thereby meeting different production situations.

[0009] The utility model has the following beneficial effects:

[0010] The utility model has a simple structure and low manufacturing cost. The induction sensor does not need to contact the moving gear. When the gear teeth are close to the sensing area of ​​the induction sensor, the induction sensor can quickly send an electrical command to the PLC controller. It can sense the operation of the transmission gears on both sides of the ring cooler in real time, thereby realizing the judgment of the operating status of the ring cooler. During the test process under multiple environmental conditions, if any transmission gear end on the left or right side fails, it can accurately output an alarm, so that the operator can find and deal with the fault in time, and avoid greater accidents.
