[0029] Specifically, the material is first conveyed from the inlet 2 to the slag cooler 1 through a rotary kiln. The material is cooled by the circulating water inside the slag cooler 1. Then, the outlet 4 of the bucket elevator 3 and the inlet of the gyratory screen 5 are connected through an external conveying pipe. The bucket elevator 3 is equipped with buckets to lift the cooled material to the outlet 4. The gyratory screen 5 is equipped with a filter assembly 6 to screen out products of different specifications such as powder and coarse and fine. The screened material is then conveyed to the feed hopper 8 through the outlet 4 inside the gyratory screen 5. A suspended weighing device 9 is installed below the feed hopper 8, with ton packages hanging below, to automatically weigh each package of material. This integrates cooling, screening and weighing functions into one unit, greatly improving production efficiency.

[0030] Reference Figure 1 The filter assembly 6 includes a first screen 61, the outer wall of which is disposed inside the swing screen 5.

[0031] Specifically, screen 1 (61), screen 2 (62), and screen 3 (63) have holes of different sizes inside for efficient filtration of materials.

[0032] Example 2, refer to Figure 2 , Figure 3 and Figure 4 Based on the above embodiments, this embodiment is used to solve the problem of quickly disassembling and assembling the feed hopper 8 to facilitate subsequent cleaning of the feed hopper 8, and is achieved through the following solution.

[0033] A connecting block 10 is fixedly connected to the outer wall of the feed hopper 8. A connecting block 2 11 is attached to the lower surface of the connecting block 10. The outer wall of the connecting block 2 11 is fixedly connected to the outer wall of the suspended weighing device 9. A connecting assembly 12 is provided on the outer wall of the connecting block 10. The connecting assembly 12 is located on the outer wall of the connecting block 2 11. The connecting assembly 12 includes a support frame 1201. The outer wall of the support frame 1201 is fixedly connected to the outer wall of the connecting block 10. A flip plate 1202 is rotatably connected to the outer wall of the support frame 1201. A stop block 1203 is attached to the outer wall of the flip plate 1202. A threaded rod 1204 is provided inside the stop block 1203. A connecting block 3 1205 is threadedly connected to the outer wall of the threaded rod 1204. The outer wall of the connecting block 3 1205 is fixedly connected to the outer wall of the flip plate 1202. The outer wall of the stop block 1203 is fixedly connected to the outer wall of the connecting block 2 11.

[0034] Specifically, by rotating the threaded rod 1204 to disengage it from the inside of the connecting block 1205, and then pulling the threaded rod 1204 outward to slide it out from the inside of the stop block 1203, the limitation on the flip plate 1202 is further removed. Then, the flip plate 1202 is rotated. When the flip plate 1202 flips and disengages from contact with the stop block 1203, the connecting block 10 is pulled upward. When the connecting block 10 moves upward, the fixing action of the connecting block 10 and the feed hopper 8 will drive the feed hopper 8 to move upward, thereby achieving the effect of quickly disassembling the feed hopper 8 for easy maintenance and cleaning in the future.

[0035] Example 3, refer to Figure 5 , Figure 6 and Figure 7 The connecting assembly 12 also includes a fixed column 1206, a sliding column 1207 slidably connected inside the fixed column 1206, a support column 1208 fixedly connected inside the sliding column 1207, a spring piece 1209 provided on the outer wall of the support column 1208, a limit column 1210 fixedly connected to the outer wall of the spring piece 1209, and the outer wall of the limit column 1210 slidably connected inside the fixed column 1206 and the sliding column 1207; the outer wall of the fixed column 1206 is fixedly connected to the outer wall of the feed hopper 8, and the outer wall of the sliding column 1207 is fixedly connected to the outer wall of the suspended weighing device 9; a groove is provided inside the limit column 1210;

[0036] Specifically, firstly, press the limiting post 1210 to make it slide inside the fixed post 1206 and the sliding post 1207, which further drives the spring piece 1209 to rotate on the outer wall of the support post 1208. The groove inside the limiting post 1210 is for the convenience of the operator to press the limiting post 1210. After the limiting post 1210 slides to the appropriate position, hold the fixed post 1206 and pull it upward. When the fixed post 1206 moves upward, the fixing action of the fixed post 1206 and the feed hopper 8 will drive the feed hopper 8 to move upward, thereby achieving the effect of quick disassembly of the feed hopper 8.

[0037] Working principle: The material in the rotary kiln first enters the slag cooler 1 through the feed port 2 for cooling, and then enters the swing screen 5 through the discharge port 4 inside the bucket elevator 3. The material of different specifications is screened by the screens 61, 62 and 63 installed inside the swing screen 5. The screened material falls into the suspended weighing device 9 through the feed hopper 8 for automatic weighing. The design of the observation window 7 facilitates real-time monitoring of the screening process, thereby integrating material cooling, screening and weighing, greatly improving production efficiency while reducing manual intervention.

[0038] By rotating the threaded rod 1204 in the reverse direction, the threaded rod 1204 will disengage from the inside of the connecting block 1205. Then, pull the threaded rod 1204 outward to make it slide out of the stop block 1203. Then, flip the flip plate 1202. The support frame 1201 is used to support the flip plate 1202 to flip. At this time, pull the connecting block 10 upward. When the connecting block 10 moves, it will drive the feed hopper 8 to move upward. Alternatively, the limiting post 1210 can be pressed in the center to make it slide inside the fixed post 1206 and the sliding post 1207. When the limiting post 1210 slides a certain distance, it will release the limitation on the fixed post 1206 and the sliding post 1207. At this time, pull the fixed post 1206 upward to drive the feed hopper 8 to move upward, thereby achieving the effect of quick disassembly of the feed hopper 8, which is convenient for later cleaning.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
