[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] In the cement production process, a grate cooler is required. The grate cooler provided by the present invention is specifically used for the cement clinker cooling operation in the cement production process. In the process of using this equipment for cooling operations, it should be noted that the temperature changes in the grate cooler should be monitored in real time using temperature sensors and other equipment to ensure that it operates within a reasonable range and avoids damage to the equipment due to excessive temperature. When adjusting the shielding mechanism 3, the operating procedures should be followed to avoid mechanical failure caused by forced operation. The water quality in the water tank 401 should be checked regularly to ensure that there are no impurities and pollutants to ensure the heat exchange effect.

[0020] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a grate cooler for cement production, comprising a grate cooler body 1, a feed pipe 2 fixedly connected to one side of the top of the grate cooler body 1, a shielding mechanism 3 provided on one side of the feed pipe 2 for shielding the feed pipe 2, the shielding mechanism 3 comprising a bottom plate 301, the bottom plate 301 being connected to the grate cooler body 1, support plates 302 fixedly connected to both sides of the top of the bottom plate 301, a folding assembly provided on one side of the support plate 302, a heat exchange mechanism 4 provided on one side of the grate cooler body 1 for absorbing excess heat generated in the grate cooler body 1, an exhaust pipe 5 fixedly connected to one side of the top of the grate cooler body 1, and a discharge pipe 6 fixedly connected to one side of the grate cooler body 1.

[0021] like Figure 2 As shown, the folding assembly includes a sliding block 303, which is connected to the support plate 302. A through hole is provided on the top of the sliding block 303, in which a screw rod 305 is screwed. Fixed plates 304 are fixedly connected on both sides of the top of the support plate 302. The fixed plate 304 is rotatably connected to the screw rod 305. A servo motor 306 is installed on the top of the fixed plate 304, and the output end of the servo motor 306 is connected to the screw rod 305. One side of the sliding block 303 is rotatably connected to a support rod 307, and the middle part of one side of the support rod 307 is rotatably connected to a fixed rod 308, which is connected to the support plate 302.

[0022] It should be noted that the support rod 307 and the fixed rod 308 are arranged in an X shape, and the baffle 310 is made of soft heat-resistant material. During use, it is first connected to the grate cooler body 1 through the base plate 301 and the support plate 302, and then the servo motor 306 on the fixed plate 304 drives the screw rod 305 to rotate and drive the sliding block 303 to move up and down along the support plate 302, and drives the connecting rod 309 to move under the action of the support rod 307 and the fixed rod 308, so that the baffle 310 is opened or closed. The shielding mechanism 3 can realize automatic operation, support remote monitoring and control, reduce manual intervention, and improve the automation level of the production line.

During use, cold water is input into the cold water area in the water tank 401 through the water inlet pipe 406, and the cold water enters the heat exchange tube 403 under the action of the water pump 404. When the cold water temperature rises, the solenoid valve 405 opens and is discharged through the drain pipe 407. The heat exchange mechanism 4 can effectively absorb and recycle the excess heat generated in the grate cooler body 1, converting it into reusable energy, significantly improving the thermal energy utilization efficiency and reducing production costs.

[0025] During use, after the feeding is stopped, the base plate 301 and the support plate 302 are first connected to the grate cooler body 1, and then the servo motor 306 on the fixed plate 304 drives the screw rod 305 to rotate and drive the sliding block 303 to move up and down along the support plate 302, and drives the connecting rod 309 to move under the action of the support rod 307 and the fixed rod 308, so that the baffle 310 is opened or closed, blocking the feed pipe 2, and the water tank 401 is divided into a cold water area and a hot water area by the partition 402. During use, cold water is input into the cold water area in the water tank 401 through the water inlet pipe 406, and the cold water enters the heat exchange tube 403 under the action of the water pump 404. When the cold water temperature rises, the solenoid valve 405 opens and is discharged through the drain pipe 407. This device can effectively prevent foreign matter from entering the interior of the grate cooler body 1 from the feed pipe 2, thereby improving the overall safety.
