Description

Technical Field

[0001] This utility model relates to the technical field of sintering ring cooler equipment, and in particular to a device for preventing material blockage during ring cooler feeding, which is a device for preventing accidents. Background Technology

[0002] Due to the special nature of the equipment and the limited space on site, the sintering ring cooler's hopper and discharge port are in a tight location and are affected by harsh environments, such as high dust and high temperature. If the discharge port becomes blocked, it will cause the ring cooler system to shut down, and in severe cases, it will cause the entire sintering system to shut down, directly affecting the quality of sintering products.

[0003] After an accident occurs, the handling process will be limited by the on-site environment and space, which will increase the difficulty for employees to handle the accident, increase the labor intensity of employees, and prolong the accident handling time. In addition, as a result, the personal safety of employees will also be affected during the operation, posing certain safety hazards.

[0004] Due to the high temperature and dust levels in the material trough during the production process, and the special location of the receiving trough, material level gauges cannot be installed in the conventional way for material level monitoring. When material blockage occurs, it causes certain problems for production.

[0005] Therefore, in order to prevent material blockage accidents at the annular cooling discharge port and improve equipment uptime, it is of great significance to invent an anti-blockage system device that can predict accidents in advance, thereby reducing the accident rate and the time required to handle accidents. Utility Model Content

[0006] The purpose of this invention is to provide a device for preventing material blockage at the feeding port of a sintering machine's annular cooling system. This device can predict material blockage at the feeding port in advance, effectively preventing material blockage or machine shutdown accidents, and is of great significance for improving equipment uptime.

[0007] This utility model provides a device for preventing material blockage at the feeding port of a sintering machine's annular cooler, including a controller module, a cable, a level gauge, an alarm, a display, and a feeding timer. The radar level gauge is installed directly above the material conveyor belt of the annular cooler. The signal data measured by the level gauge is transmitted to the controller module via the cable, and then processed by the internal program of the controller module and displayed on the display. If the radar level gauge does not detect a high peak value in the sintered mineral material within a preset time set by the feeding timer, it outputs an alarm to the alarm.

[0008] Furthermore, the radar level gauge is mounted on the support of the material conveyor belt via a fixed bracket.

[0009] Furthermore, the alarm is an audible and visual alarm.

[0010] Furthermore, the audible and visual alarm is installed on-site.

[0011] Furthermore, the audible and visual alarm is installed in the controller module.

[0012] Furthermore, the level gauge is a radar level gauge.

[0013] Furthermore, the preset time in the feeding timer is set differently depending on the material.

[0014] Furthermore, the preset time is 4-8 minutes.

[0015] Furthermore, the material level range for the ring cooler is 500mm-10mm.

[0016] Furthermore, if the level gauge does not detect a high level signal within a preset time, it outputs a chain shutdown signal to the controller module.

[0017] The beneficial effects of this utility model are as follows: when it is impossible to use a separate level gauge to measure the special area of ​​the annular cooler's discharge port, it can prevent the occurrence of material blockage accidents at the annular cooler's discharge port, improve the equipment's operating rate, and make advance predictions when accidents occur. This is of great significance for reducing the accident rate, reducing accident handling time, and increasing sinter production. Attached Figure Description

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1 As shown, this utility model provides a device for preventing material blockage in the feeding of an annular cooler, including a controller module 1, a cable 2, a level gauge 3, an alarm 4, a display 9, and a feeding timer 10. The radar level gauge 3 is installed directly above the material conveyor belt 5 of the annular cooler, maintaining a distance of 5 meters from the feeding port 7 (this distance can be adjusted according to the actual site conditions, mainly considering the influence of the environment on the radar level gauge). The signal data measured by the level gauge 3 is transmitted to the controller module 1 through the cable 2, and then processed by the internal program of the controller module 1 and displayed on the display 9. If the radar level gauge 3 does not detect a high peak value in the sintered mineral material 6 within the preset time set by the feeding timer 10, it outputs an alarm to the alarm 4.

[0026] The radar level gauge 1 is mounted on the support of the material conveyor belt 5 via a fixed bracket 8. The alarm 4 is an audible and visual alarm. The audible and visual alarm is installed on-site or in the controller module 1. The level gauge 3 is a radar level gauge.

[0027] The preset time in the feeding timer 10 varies depending on the material. The preset time is 4-8 minutes. The material level range of the annular cooler is 500mm-10mm.

[0028] If the level gauge 3 does not detect a high level signal within a preset time, it outputs a chain shutdown signal to the controller module 1.

[0029] The specific implementation is as follows:

[0030] The radar level gauge 3 transmits its signal to the controller module 1 in the central control unit via cable 2. The controller module 1 performs internal programs and calculations. During normal production, the material level fluctuates between 500mm and 10mm. The discharge timer 10 shows a maximum peak every 4 minutes, indicating normal production operation. When the radar level gauge 3 reaches its lower limit (e.g., 10mm) and exceeds the discharge timer 10, the discharge timer 10 can be adjusted on the display 9 screen according to the production rhythm or the volume of the annular cooling machine trolley. If the radar level gauge 3 does not detect the maximum peak value, the controller module 1's internal program will ultimately output an alarm signal to the audible and visual alarm 4. The audible and visual alarm 4 is installed on-site or in the main control unit. Personnel can use the alarm 4 to check the annular cooling machine discharge port 7 for blockages. If a blockage is found, it can be cleared immediately, preventing prolonged blockages from causing production downtime.

[0031] If the personnel do not arrive at the site in time, and the radar level gauge 3 does not detect a high level signal within the preset time of 4 minutes of the feeding timer 10, it can also directly output an interlocking shutdown signal, and then organize an inspection of the site to avoid prolonged material blockage and reduce processing time.

[0032] The working principle of this utility model is as follows: Under normal production conditions of the sintering machine, based on the regular characteristics of the material feeding of the sintering ring cooler, a radar level gauge 3 is installed at a suitable position on the material belt 5 of the ring cooler. The collected material level signal is transmitted to the controller module 1 through the cable 2 to collect the instantaneous feeding amount in real time. Based on the continuity of production and the regularity of the material feeding of the ring cooler, if the material flow signal is detected to be too low within the set time, an audible and visual alarm can be output to remind the main control operator to check whether there is any abnormality at the feeding port. If no material signal is collected for more than the set time, an interlocking shutdown signal is directly output to avoid material blockage at the feeding port.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
