Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cooling, in particular to a cooling system for a ring cooler. Background Art
[0002] The cooling of sintered ore and pelletized ore is a crucial step in the sintering and pelletizing process. Annular coolers, as the primary cooling equipment, are widely used in sintering and pelletizing processes. Currently, the cooling of materials on the annular cooler relies primarily on the air flow from the annular cooling blower. During normal production, the ore on the annular cooler can be cooled. However, when production conditions suddenly change, the material often fails to cool to the designed temperature, causing burns on downstream conveyor belts and even fires. Current designs typically test the material temperature after unloading the annular cooler and then implement appropriate measures, such as injecting water into subsequent conveyor belts, which is equivalent to post-processing. If relevant issues can be identified and addressed before the annular cooler is unloaded, and the material temperature at the annular cooler discharge can be strictly controlled, this will have great practical significance for sintering and pelletizing production and can improve production safety and stability.
[0003] Therefore, it is necessary to improve the existing technology. Summary of the Invention

[0019] In order to better understand the present invention, the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0020] like Figure 1 A cooling system shown, specifically a cooling system for a ring cooler, includes a temperature monitoring device 3 and a water cooling device 4 that can form a water curtain;
[0021] The ring cooler includes a ring cooler body 1, which is provided with a loading port 1.5 and a discharging port 1.4; a material 2 such as sintered ore or pelletized ore is arranged inside the ring cooler body 1 and can rotate circumferentially inside the ring cooler body 1;
[0022] The temperature monitoring device 3 is arranged in the annular cooler body 1 upstream of the discharge port 1.4, and is used to monitor the temperature of the material in the annular cooler body 1 in real time;
[0023] The water cooling device 4 is disposed in the ring cooler body 1 and is located downstream of the temperature monitoring device 3 for water cooling of the sintered ore or pelletized ore.
[0024] In the present invention, when the temperature monitoring device 3 detects that the temperature of the sintered ore is higher than the set temperature, the water cooling device 4 is started to cool the material 2 so that the temperature of the material 2 is lower than the set discharge temperature.
[0025] In the present invention, a temperature monitoring device 3 is additionally provided between the water cooling device 4 and the discharge port 1.4. That is, two temperature monitoring devices 3 are provided within the annular cooler body 1: one upstream of the water cooling device 4 and one downstream of the water cooling device 4, respectively detecting the temperature of the material 2 before and after water cooling. These temperature monitoring devices 3 utilize existing equipment.
[0026] Preferably, the water cooling device 4 includes a water supply pipe 4.1 and a nozzle 4.2; the inlet of the water supply pipe 4.1 is connected to the water source, and both ends of the water supply pipe 4.1 are fixed to the ring cooler frame 1.1 of the ring cooler body 1 (specifically, the two ends of the water supply pipe 4.1 are connected to the ring cooler frame 1.1 through a cantilever rod), and the axial direction of the water supply pipe 4.1 is consistent with the radial direction of the ring cooler body 1; there are multiple nozzles 4.2, which are arranged at intervals along the axial direction of the water supply pipe 4.1.
[0027] In this embodiment, Figure 2 As shown, four groups of water cooling devices 4 are arranged at intervals along the circumferential direction in the ring cooler body 1 between the temperature monitoring device 3 and the discharge port 1.4; six nozzles 4.2 are respectively provided on the water supply pipe 4.1 of each group of water cooling devices 4.
[0028] In the present invention, a main valve is provided on the water supply main 4.1. Cooling water is sprayed out through the nozzle 4.2 to form water mist, which cools the sintered ore or pelletized ore on the ring cooler body 1.
[0029] In this embodiment, Figure 2 As shown, the annular cooler body 1 includes an annular cooler frame 1.1, a rotating body 1.2 and a driving mechanism 1.3; the rotating body 1.2 is installed on the annular cooler frame 1.1, and the driving mechanism 1.3 is arranged on the outside of the rotating body 1.2. The driving end of the driving mechanism 1.3 is connected to the input end of the rotating body 1.2, driving the rotating body 1.2 to rotate circumferentially along the annular track 1.8 provided on the annular cooler frame 1.1; the water cooling device 4 is located above the rotating body 1.2, and both ends of the water supply main 4.1 are connected to the annular cooler frames 1.1 on both sides.
[0030] In the present invention, the annular cooler is an existing mature equipment, which, in addition to the above configurations, also includes a smoke hood, a fan, a smoke exhaust device, an ash hopper 1.7, etc. The structure and function of the annular cooler are all existing technologies and will not be repeated here.
[0031] The working principle of this utility model is:
[0032] Material 2, such as sintered ore or pelletized ore, is loaded onto the rotating body 1.2 of the ring cooler body 1 from the loading port 1.5 of the ring cooler body 1. Driven by the driving mechanism 1.3, the material 2 rotates circumferentially inside the ring cooler body 1 along with the rotating body 1.2 and is cooled by the cold air supplied by the fan. The temperature monitoring device 3 inside the ring cooler body 1 detects the temperature of the material 2. When it is detected that the temperature of the material 2 is higher than the set discharge temperature, the staff starts the water cooling device 4 according to the temperature difference, opens the main valve on the water supply pipe 4.1, and cooling water enters the nozzle 4.2 through the water supply pipe 4.1 and is sprayed out from the nozzle 4.2 to form a water curtain, cooling the material 2 in the ring cooler body 1, so that the temperature of the material 2 drops below the set discharge temperature, and then the material is discharged from the discharge port 1.4 of the ring cooler body 1 to enter the subsequent process.
[0033] The present invention can also introduce a controller. The main valve on the water supply main 4.1 adopts a solenoid valve, which is connected to the controller, and the controller controls the opening and closing of the main valve; the temperature monitoring device 3 adopts an infrared detector (to detect the temperature distribution of the sintered ore or pellets, and to monitor the sintered ore temperature in real time around the clock based on the sintered ore discharge temperature data), which is connected to the controller. The temperature monitoring device 3 sends the detected temperature data to the controller, which receives the temperature data and compares it with the set discharge temperature, opens the main valve, and causes the nozzle 4.2 to spray cooling water to form a water curtain to cool the sintered ore or pellets, so that the temperature of the sintered ore or pellets drops below the set discharge temperature, and then discharges the sintered ore or pellets from the discharge port 1.4 of the ring cooler body 1.
[0034] In the present invention, if the material 2 is cooled by the water cooling device 4 and the downstream temperature monitoring device 3 detects that the temperature of the material 2 is still higher than the set discharge temperature, it can be cooled again by the water pumping measure of the belt conveyor in the subsequent process.
[0035] In this embodiment, the temperature monitoring device 3 is an infrared detector. The infrared detector detects the temperature distribution of the sintered ore or pelletized ore and monitors the sintered ore temperature in real time around the clock based on the sintered ore outlet temperature data.
