Description

Technical Field

[0001] The utility model relates to the technical field of screening machines, in particular to a screening machine for non-metallic mineral products. Background Technique

[0002] The flat magnetic separator is used for the separation and impurity removal of non-metallic mineral ores or slag, separating the concentrate and waste stones in the raw ore, so as to improve the metal grade of the concentrate.

[0003] First, when the existing magnetic separator screens out ores, all ores will be transported to the blanking chute. Since the sizes of the produced ores are inconsistent and ores of different sizes have different functions, the screened ores need to be classified by using screening equipment, resulting in poor screening effect of the existing screening machine, long screening time, and reduced screening efficiency.

[0004] Second, when the magnetic separator screens ores, the sludge carried by the ores will be washed into the sludge chute by high-pressure water flow. However, due to the high viscosity of the sludge, the output port is often blocked during output, and then workers need to manually dredge it, which is time-consuming and laborious, resulting in poor practicability of the existing screening equipment.

When the ore descends, it will be blocked by the screening plate 9, and the screening plates 9 with different mesh sizes will screen out ores of different sizes respectively. When the ore accumulates, the lifting rod 13 is moved up and down, so that one side of the uppermost clamping plate 10 is driven to move up, driving all other clamping plates 10 to rotate on the side plate 6 with the center of the movable rod 11, thereby changing the inclination angle of the screening plate 9. Moving the lifting rod 13 up and down back and forth can shake the butted ore apart, and then continue screening. The mutual cooperation of multiple components can not only realize the classification screening of ores of different sizes, but also disperse the ore when it accumulates, not only improving the screening effect, but also improving the screening efficiency.

[0024] Specifically, a side of the movable plate 3 close to the side plate 6 is bolted with an embedding plate 5 , and an embedding groove 7 is formed on the side plate 6 , and the embedding plate 5 is movably embedded in the embedding groove 7 .

[0025] Through the above technical solution, the movable plate 3 is plugged into the side plate 6 through the interlocking plate 5, which is convenient for loading and unloading.

[0026] Specifically, the top of the clamping plate 10 at the top is bolted to a lifting rod 13 , and other clamping plates 10 are bolted to each other through a connecting rod 14 , and the top of the lifting rod 13 movably passes through the screening box 2 .

[0027] Through the above technical solution, every two splints 10 close to each other form a group, and the distance between each group of splints 10 is equal to the thickness of the screening plate 9. The positions of each group of splints 10 on the two side panels 6 correspond to each other, and the connecting rod 14 connects each group of splints 10 located on the same side panel 6 together.

[0028] Specifically, a movable rod 11 is bolted to one side of the clamping plate 10 close to the side plate 6 , and the movable rod 11 is movably engaged with one side of the side plate 6 close to the clamping plate 10 .

[0029] Through the above technical solution, moving the lifting rod 13 up and down can drive the clamping plate 10 to rotate back and forth along the center of the movable rod 11.

[0032] Specifically, an extension rod 18 is bolted to the top of the dredging net 17 , and a telescopic rod 19 is bolted to one end of the extension rod 18 away from the dredging net 17 .

[0033] Through the above technical solution, the dredging net 17 is composed of mutually perpendicular blades, and the sludge blocked in the sludge tank 16 can be cut when the dredging net 17 moves up and down.

[0034] Specifically, the bottom of the telescopic rod 19 is bolted to the servo motor 20 , the telescopic rod 19 movably passes through the screening device 1 , and the servo motor 20 is bolted inside the servo motor 20 .

[0035] Through the above technical solution, the servo motor 20 can drive the telescopic rod 19 to move up and down at a certain frequency.

[0036] During use, pull the movable plate 3 in the direction away from the screening device 1, so that the movable plate 3 drives the side plate 6 and the screening plate 9 on the side plate 6 to move out of the screening box 2. Move the movable plate 3 upward to move the fitting plate 5 out of the fitting groove 7, and then the movable plate 3 can be removed from one side of the two side plates 6. At this time, select screening plates 9 with different mesh sizes according to the screening requirements, and insert the corresponding screening plates 9 between the two groups of clamping plates 10 in the order of the mesh size from large to small from top to bottom. When the card slot 15 on the screening plate 9 corresponds to the card block 12 on the clamping plate 10, the card block 12 will be embedded in the card slot 15. At this time, the screening plate 9 will be fixed between the two side plates 6. Then reinstall the movable plate 3 on the side plate 6 and push the movable plate 3 back into the screening box 2. The conveyor belt in the screening device 1 will transport the screened ore to the blanking chute 4. When the ore descends, it will be blocked by the screening plate 9. Screening plates 9 with different mesh sizes will block ores of different sizes at the top. When the ore accumulates, move the lifting rod 13 up and down to drive the upper side of the uppermost clamping plate 10 to move upward. Since the clamping plate 10 is rotationally connected to the side plate 6 through the movable rod 11 and each group of clamping plates 10 is connected through the connecting rod 14, when the upper side of the uppermost clamping plate 10 moves upward, it will drive all other clamping plates 10 to rotate along the center of the movable rod 11 on the side plate 6, thereby changing the inclination angle of the screening plate 9. Move the lifting rod 13 up and down back and forth to shake the docked ore loose, and then continue screening. The sludge generated during the screening of the screening device 1 will be output through the sludge tank 16. When the sludge tank 16 is blocked, turn on the servo motor 20 through the external control terminal to drive the telescopic rod 19 to move up and down. The telescopic rod 19 drives the dredging net 17 to move up and down in the sludge tank 16 through the extension rod 18 to cut the sludge blocked in the sludge tank 16, thereby achieving the dredging effect.
